The software to get real throughput out of it does not. +Local AI should be a default, not a privilege: private data, no per-token bill, no vendor lock-in. The hardware to run capable models already sits on desks. The software to run those chips well doesn't. -Nothing was built for local AI inference. Most machines bolt a stock GPU onto a desktop CPU and run a stock runtime, never tuning the kernels to the silicon underneath. On the same 27B model, a DGX Spark or Mac Studio leaves four to six times the real throughput on the table. General-purpose frameworks won the last decade because hand-tuning per chip cost more than it returned: one stack, decent on everything, great on nothing. Speculative decoding, speculative prefill, and fused megakernels turn idle silicon into 3-10× speedups, but they stay locked to BF16 weights on data-center GPUs. Consumer cards inherit the leftovers. +General-purpose frameworks dominated the last decade because hand-tuning kernels per chip was too expensive to justify. One stack, decent on everything, great on nothing. Most of the silicon's capability stays on the floor. -**See the benchmarks and the machine at [lucebox.com](https://lucebox.com).** +AI-assisted development flips that calculus. Rewrites that took a quarter now fit in a release cycle. Lucebox is where we publish them, one chip and one model family at a time. Apache 2.0 source, full writeup, reproducible benchmarks. -

Rebuild + re-tag before + sweeping a profile whose bracket varies fa_window. + +- **The DFLASH allowlist is duplicated.** `sweep.DFLASH_ALLOWLIST` and + the strict 11-field set referenced in `cli.DFLASH_ALLOWLIST` need to + stay in lockstep.

If not: + `lucebox models download --activate`. +2. Activate the preset: `lucebox config set model.preset=` (and + `model.target_file` / `model.draft_file` if the registry default + isn't what you want). +3. Restart the service; verify the new arch boots: + `journalctl --user -u lucebox.service -n 30 | grep arch=` +4. Confirm the bracket builder has a branch for your preset. If not, + add one in `autotune.py` modeled on `_coding_agent_loop_gemma_bracket` + or `_coding_agent_loop_qwen_bracket`. The key axis decisions: + - Does the arch backend respect `cache_type_k/v`? gemma4 does not + (hardcoded F16 in the loader); qwen35 does. Include the KV-quant + axis only when the backend respects it. + - What's the proven max_ctx ceiling on your VRAM tier? Use VRAM + math from architecture metadata (`n_layer`, `n_head_kv`, + `head_dim`, sliding-window pattern) — see the gemma4 32-31 GB + tier comment in `_coding_agent_loop_gemma_bracket` for the + reasoning. + - Does PFlash need a separate drafter file you've configured? + Leave pflash=off in the bracket if not, and add it later when + `prefill_drafter` is wired up. +5. If the bracket adds a new axis (e.g. `--reasoning-effort`): + - Add the field to `DflashRuntime` in `types.py` + - Plumb it through `docker_run.py` → `entrypoint.sh` → server CLI + - Add it to `DFLASH_ALLOWLIST` in `sweep.py` and the registry in + `config.py` + - Add a regression test mirroring the existing + `test_fa_window_in_dflash_allowlist` test +6.

The differences are small (~3-7%) + but consistent. fa_window's sparse-decode optimization is wasted + compute on a 26B-A4B-MoE model where decode bandwidth isn't the + bottleneck at 90K tokens. + +4. **`budget` axis is nearly flat at 90K prompt size.** 16/22/32 produce + 3.5/3.4/3.2 tok/s — small enough margin that noise dominates. The + heuristic default of `budget=22` is fine; the sweep's preference for + `budget=16` is within run-to-run variance. + +5. **Decode throughput at 90K prompt: ~3.5 tok/s.** Mostly prefill cost: + wall=72s, ~256 completion tokens, so decode-phase is ~30s for 256 + tokens (~8.5 tok/s decode-only).

Why sindri appeared to fail at 131K (fixture picker issue) + +The sindri sweep (`gemma4-26b-coding-agent-loop-sweep-2026-05-30.md`) +reported all 131K cells failing with HTTP 400. At the time, the fixture +picker selected the **100K-bucket case** (`context_tokens_approx ≈ 102397`) +for max_ctx=131072.

The picker's +`safety_factor=0.7` was likely updated between the two runs, changing the +effective budget threshold from `1.0 × (max_ctx − 4096)` to +`0.7 × (max_ctx − 4096)`: + +- Old: effective_budget = 126976 × 1.0 = 126976 → 100K case (102397) fits ✓ +- New: effective_budget = 126976 × 0.7 = 88883 → 64K case (65205) fits ✓, + 100K case (102397) does not ✗ + +So sindri's 131K failures were a **fixture selection artifact, not a VRAM +limit**. The hardware could handle it; the test picked a case that was too +large for the server's request ceiling. + +### 3. fa_window gives no benefit for Gemma 4 at 90K-token context + +fa_window=0 (full attention) and fa_window=2048 produced identical throughput +(2.0 tok/s, within noise) across all budget/max_ctx combinations. This +replicates the sindri finding: Gemma 4 26B-A4B's decode is not +bandwidth-bound at this scale in a way that sparse-attention windowing +improves. fa_window=0 is the recommended default. + +### 4. Budget insensitive on Gemma's MoE architecture + +budget=16, 22, and 32 all score ~2.0 tok/s (within ±0.1 tok/s noise) at +both context sizes. The draft budget has minimal leverage on Gemma 4 26B-A4B: +the 4B-active MoE decoder is already fast enough that more speculative tokens +don't meaningfully amortize verification cost. budget=22 (the heuristic +default) is fine; there's no need to tune this axis further. + +### 5. Gemma is faster than Qwen3.6 at long context + +At 98K context (both using the same 64K case): +- Gemma 4 26B-A4B: **2.0 tok/s**, 64 s wall (90K actual tokens) +- Qwen3.6 27B: **1.2 tok/s**, 209 s wall (~85K actual tokens) + +Gemma's 4B-active MoE architecture decodes ~67% faster than Qwen3.6's denser +27B at equivalent real-token prompt sizes. + +## Heuristic updates applied + +**`autotune.py` — `_coding_agent_loop_gemma_bracket()` docstring:** +Updated to note that 131K is confirmed viable on 23–24 GB VRAM.

Per the +[opcnew analysis](https://www.opcnew.com/en/gemma-4-thinking-tokens-system-prompt-control) +this is reported to be inherent to Gemma 4's training (reasoning is +emergent, not instruction-gated) and natural-language "do not reason" +in the system prompt is unreliable. + +## Q3a — Hard-close budget mechanism + +**Server-side budget enforcement: WORKS PRECISELY.** + +| mode | budget_tokens | comp_tokens | comp - budget | +|---|---|---|---| +| `think-low` | 1024 | 1536 | 512 | +| `think-medium` | 4096 | 4608 | 512 | + +`comp - budget = 512` for both, matching `/props.budget_envelope.hard_limit_reply_budget = 512` exactly. The +server cleanly closes thinking at `budget_tokens` and reserves 512 +tokens for a content reply. + +**Post-close coherence: BROKEN.** The content emitted after the +forced thinking-close is garbage on both think-low and think-medium: + +`think-low` content (full): +``` +To find the area own of the--------- ---- - - - - - - - - - - ... +``` + +`think-medium` content: +``` +To find-the area of the triangle formed by the points $A(0,0)$, +$B(1,1)$, and $C(2,0)$... [solves a different, hallucinated +problem then degenerates] +``` + +The model gets force-closed mid-reasoning and can't recover to +produce a coherent final answer. Reasoning content also degenerates +*before* the close fires (`$M$-$N$ is-$P$ is $Q$-...`), suggesting +the model was already losing coherence well inside the budget — a +sampling / model issue, not a budget issue (see sampling caveat). + +**No thinking-tokens-flow-into-content failure mode.** With the +hard-close active, the post-close output is in `content`, not +`reasoning_content`. The server's transition firmly switches +channels. The badness is the *model's* failure to write a useful +content reply, not the server crossing channels. + +## Q3b — Prompt-side control + +**`think-raw-noprompt`** (system prompt empty, `enable_thinking=false` +in template, `thinking: {type: enabled}` in body) emitted **zero** +reasoning content and 18733 chars of content. So with the template's +`<|think|>` opener suppressed, the model does *not* self-open a +thought channel even when the server's budget contract says +thinking is enabled. + +This confirms what the model card states and what the research +agent found: thinking is gated by the `<|think|>` token in the +**system turn** of the chat template, not by anything in the request +body. The server's `thinking: {type: enabled}` field is only +meaningful when the chat template also primes the model with +`<|think|>`. + +**Practical implication**: the chat template +is the source of truth for whether Gemma 4 thinks. The Anthropic-shape +`thinking: {type}` field is just a hint into the chat template +render (via `chat_template_kwargs.enable_thinking`). + +## Q3c — Model card guidance + +`share/model_cards/gemma-4-26b-a4b-it.json` says verbatim: + +> Reasoning-capable via `<|think|>` token at start of system prompt. + +Recommended sampling: +```json +"sampling": { + "temperature": 1.0, + "top_p": 0.95, + "top_k": 64, + "min_p": 0.0, + "presence_penalty": 0.0, + "repetition_penalty": 1.0 +} +``` + +`/props.budget_envelope.effort_tiers`: low=1984, medium=7936, +high=15872, max=15872, default `think_max_tokens=15488` (server-side +defaults derived from `max_tokens=16384` minus `hard_limit_reply_budget=512`). + +## Q3d — Research agent findings (summary) + +Spawned a research agent (see this session's full notes); highlights: + +1. Gemma 4 thinking tokens: `<|think|>` (id 98) opens *globally* in + the system turn; `<|channel>thought` (id 100) opens the per-turn + reasoning block; `` (id 101) closes it. Distinct from + Qwen3's `` / `` text-level markers. +2. **vLLM issue #38855**: their parser strips `<|channel>`/`` + via `skip_special_tokens=True` before parsing → reasoning leaks + into `content`. Same failure mode we'd hit if we matched by text + instead of token-id. +3. **llama.cpp PR #21697**: wired up `--reasoning-budget` for gemma4 + by matching against the channel-thought token-id explicitly. Our + server's hard-close should target token id **101**, not + ``. +4. **Google docs recommend pre-seeding** an empty + `<|channel>thought\n` in the assistant turn for the + 26B/31B when you want non-thinking output — because the larger + variants sometimes open a thought channel even with + `enable_thinking=false`. Our `f1d30f2` chat-template fix already + does this pre-seeding; our nothink result above (zero + `reasoning_content`) confirms it works. +5. **Multi-turn caveat**: Google's docs say strip prior-turn + thoughts between turns. Our KV-cache currently preserves them — + open follow-up. +6. F16 GGUFs on CUDA flood `` tokens when thinking is + forced on; Q4_K_M is the workaround (we're already on Q4_K_M). +7. 31B reports "blank line" / continued-thinking-after-close on + unsloth GGUF discussion #6 — relevant if we hit similar issues + when we run the same probe against 31B. + +## Sampling caveat (read before drawing conclusions) + +All five modes were run at temp=0 (greedy decode) for +reproducibility. The model card recommends temp=1.0, top_p=0.95, +top_k=64 for Gemma 4. The pervasive `- - - -` / `$0-0.` / +`$M$-$N$-$P$-` degeneration loops seen across modes are consistent +with greedy-decode collapse on Gemma 4 — *not* with a thinking-control +bug. The mechanism-level findings (parser separation, budget +enforcement, no token leakage, template gating) are robust to +sampling. The "model never closes thinking" and "post-close content +is garbage" findings are likely sampling-driven and should be +re-tested at temp=1.0 before concluding the model fundamentally +can't terminate. + +A follow-up run at the model card's recommended sampling is queued. + +## Addendum 1 — Retry at the model card's recommended sampling + +Re-ran three modes with temperature=1.0, top_p=0.95, top_k=64, seed=42 +(see `tuning-snapshots/...-mcsampling/`): + +| mode | comp | content | reasoning | finish | got 588? | +|---|---|---|---|---|---| +| `think-default` | 8192 | 1131 | 14867 | length | no — derails mid-derivation | +| `nothink` | 4241 | 8579 | 0 | **stop** | **yes** (final line: `QED ==> 588`) | +| `think-medium` | 4608 | 961 | 8046 | length | no | + +**The greedy-decode degeneration is gone at sampled decode.** All +three runs are coherent throughout (no `- - - -` repeats). + +**Surprising headline**: at sampled decode, `nothink` is the only +mode that produces a correct, terminated answer. The two thinking +modes both hit `length` because the model gets lost in the dedicated +`<|channel>thought` channel and never finalizes within an 8192-token +budget. The model has a much stronger termination prior in `content` +than in the reasoning channel. + +## Addendum 2 — Brevity-compulsion experiments + +User pushback: "if thinking == nothink in terms of content and length +and the only difference is presence of `` tags, that's an +important observation. It has downstream implications." + +To test whether *any* prompt-side mechanism can compel Gemma 4 to +actually produce a brief answer (rather than reasoning at length in +either channel), ran three additional nothink variants at temp=1.0 +(see `tuning-snapshots/...-brevity/`): + +| mode | comp | content | finish | got 588? | +|---|---|---|---|---| +| `nothink` (baseline) | 4241 | 8579 | stop | yes | +| `nothink-terse` (system="Answer with ONLY the final answer.

So even forced cutoffs +don't save work — they just hide more output. + +### What's actually a compute lever on Gemma 4? + +Based on the data we have: + +1. **`max_tokens`** — hard truncation. Saves compute. Loses answer. +2. **Server force-close at `budget_tokens`** — same: hard cut at + budget+512, post-close content is garbage. Saves compute, loses + answer. +3. **Chat-template `enable_thinking=true/false`** — controls only + *which channel* the reasoning lands in (reasoning_content vs + content). Compute is the same. Channel choice can change + termination behavior (`enable_thinking=false` *helps* terminate, + per Addendum 1, because content has a stronger end-prior than + the reasoning channel). +4. **Natural-language system prompts ("answer briefly", "don't + reason")** — **fully ignored** by the model. Matches the opcnew + research finding that reasoning is emergent from Gemma 4's + training, not instruction-gated. +5. **Stop sequences** — work at the output level only; don't save + compute, lose the model's actual answer if it comes after the + stop trigger. +6. **Prefill assistant turn** — tested with `"The answer is "` + prefix; model treats it as a setup and elaborates at length. + Made things worse. + +### Downstream implications + +- **"Thinking budget" isn't a knob for Gemma 4** the way it is for + Qwen3. For Qwen3 a budget triggers wrap-up behavior because the + model is trained to close `` and answer. Gemma 4 just + gets truncated mid-derivation and emits garbage afterward. +- **`reasoning_content` vs `content` is mostly cosmetic.** Clients + can't actually "opt out of reasoning compute" — only "opt out of + the reasoning channel". Pass-rate comparisons between + `--think`/`--no-think` on Gemma 4 are measuring channel routing, + not thinking behavior. +- **For agentic use, `nothink` may be the right default for Gemma 4 + on hard cases** because thinking-mode doesn't finalize within + reasonable budgets, while nothink does (and gets the same answer, + in `content`). +- **Our bench harness should report `wall_s` and `comp_tokens` + alongside think/nothink labels** — the conventional "think saves + no-think loses" interpretation may invert here. + +## Concrete follow-ups + +1. **Server: fix `reasoning_tokens` accounting in Gemma4Backend.** + Currently always 0; need to count tokens emitted between + `<|channel>thought` (id 100) and `` (id 101) and surface + in both `usage.thinking_tokens` and + `usage.completion_tokens_details.reasoning_tokens`. +2. **Server: port qwen35 timing instrumentation (`3b80fa8`) to + Gemma4Backend.** `decode_ms=0, decode_tokens_per_sec=0` is + pretending nothing happened. +3. **Server: fix the `thought` text prefix leak** at the start of + `reasoning_content`. The `<|channel>thought` token text needs to + be dropped atomically by the SSE emitter, not partial-matched. +4. **Server: validate hard-close transition recovery.** When the + server force-closes thinking, the model often emits garbage in + the content phase. Two possible mitigations: (a) emit a short + transitional cue (e.g. `\nFinal answer: `) after the + forced close to nudge the model into answer mode; (b) when the + model fails to emit useful content within N tokens of the + forced close, give up and surface a `finish_details.error = + "post_close_degenerate"` so callers can retry with a larger + budget. +5. **Re-run probe at the model card's recommended sampling** + (temp=1.0, top_p=0.95, top_k=64) to disentangle sampling-driven + degeneration from thinking-control issues. Add a `--sampling` + knob to `probe_thinking_control.py`. +6. **Multi-turn KV-cache: strip prior-turn thoughts** between turns + per Google's guidance (research item 5). Likely needs a + conversation-state pass over `cache_.target_feat` after each + turn closes. +7. **Repeat against gemma-4-31b** to see whether the 31B's + reported "continued-thinking-after-close" issue (research item 7) + manifests in our setup. diff --git a/docs/experiments/gemma4-31b-initial-characterization-bragi-2026-05-31.md b/docs/experiments/gemma4-31b-initial-characterization-bragi-2026-05-31.md new file mode 100644 index 000000000..ae9667126 --- /dev/null +++ b/docs/experiments/gemma4-31b-initial-characterization-bragi-2026-05-31.md @@ -0,0 +1,141 @@ +# Gemma4-31B Initial Characterization — bragi — 2026-05-31 + +## Hardware + +bragi: RTX 5090 Laptop MaxQ, 23 GB VRAM (24,463 MiB), WSL2, Windows Balanced (~86-90W TDP) + +## Model + +| field | value | +|-------|-------| +| preset | `gemma-4-31b` | +| target | `google_gemma-4-31B-it-Q4_K_M.gguf` — 20 GB | +| draft | `gemma-4-31B-it-DFlash-q8_0.gguf` — 1.6 GB | +| architecture | gemma4, 60 layers (dense 30.7B params) | +| context | 262,144 tokens native (256K) | +| embed | 5376 | +| reasoning | via `<|think|>` token | + +## Server Config (initial sweep, 32K context, nothink) + +```toml +[model] +preset = "gemma-4-31b" + +[dflash] +budget = 8 +max_ctx = 32768 +cache_type_k = "tq3_0" +cache_type_v = "tq3_0" +think_max = 8192 +prefix_cache_slots = 0 +``` + +Image: `lucebox-hub:cuda12` (= `dc20057e-cuda12`) + +## Server Capabilities + +| capability | status | notes | +|-----------|--------|-------| +| DFlash speculative | ✓ active | `speculative_mode=dflash`, budget=8 | +| `/v1/messages` tools | ✗ (model) | Server accepts requests, model ignores tool schema | +| `/v1/chat/completions` tools | ✗ | `tools_supported=False` in props | +| Reasoning (`<|think|>`) | ? | `reasoning_supported=False` in props — arch wiring TBD | +| KV quantization | ✓ tq3_0 | Unlike Gemma4-26B-A4B which forces F16 | + +## Differences vs Prior Models + +| aspect | Gemma4-26B-A4B | Gemma4-31B | Qwen3.6-27B | +|--------|----------------|------------|-------------| +| params | 4B active / 26B total (MoE) | 30.7B dense | 27B dense | +| VRAM target | 17 GB | 20 GB | 17 GB | +| VRAM draft | 457 MB | 1.6 GB | 1.4 GB | +| Max safe ctx | 131K (F16 KV) | ~32K (tq3_0) | 98K (tq3_0) | +| KV quant | F16 forced (26B arch) | tq3_0 (31B arch) | tq3_0 | +| Reasoning | `<|think|>` | `<|think|>` | `` | + +## Benchmark Results (32K context, nothink) + +Baseline: `bragi-rtx5090laptop-gemma4-31b-nothink-32k-2026-05-31` + +| area | n | pass_rate | wall_total | wall_median | Qwen3.6 ref | notes | +|------|---|-----------|------------|-------------|-------------|-------| +| forge | 30 | ~0% | skip | skip | 100% | Model generates prose instead of tool_use blocks (expected — consistent with gemma4-26b) | +| agent_recorded | 26 | **38.5%** | 629s | 23.4s | 38.5% | Re-run with `--max-tokens 512`; matches Qwen3.6 exactly | +| code | 10 | **70.0%** | 117s | 10.6s | 90% | Re-run with `--max-tokens 512`; -20pp vs Qwen3.6 | +| gsm8k | 100 | **95.0%** | 1922s | 11.8s | 81% | math, nothink — **+14pp vs Qwen3.6** | +| hellaswag | 100 | **79.0%** | 310s | 1.4s | 93% | MC knowledge — -14pp vs Qwen3.6 | +| truthfulqa-mc1 | 100 | **79.0%** | 438s | 0.4s | 82% | MC truthfulness — -3pp vs Qwen3.6 | +| longctx | 6 | **33.3%** (2/6) | 15s | — | 100% | frontier-2k,4k pass; 8k+ → HTTP 400 (template overflow at 32K) | +| smoke | 3 | 100% | 2s | — | 100% | confirmed passing | + +## CRITICAL: DFlash Server Hang Bug + +**Trigger**: Running a forge benchmark (Anthropic `/v1/messages`, `stream=false`) for Gemma4-31B +leaves a long conversation in-flight when the forge client is killed.

This is a model behavior limitation, +not a server bug. + +### Why the fix is critical for Qwen3.6 + +Qwen3.6 uses turn-by-turn tool calling: call one tool, receive the result, call the +next. This requires multi-turn conversation with proper tool_result context. Without +the fix, each turn was sending only role delimiters (+10 tokens) instead of actual +results, so the model kept calling the same tool in a loop (15 iterations → FAIL). +With the fix: 2–4 calls per scenario, all pass. + +## Why `--think`/`--no-think` don't affect forge + +The forge runner uses `forge_eval._forge.clients.anthropic.AnthropicClient` +which sends raw Anthropic SDK requests. The luce-bench `thinking_control` +injection runs in a different path (the `_prompt_thinking_control()` wrapper +in `runner.py`). For forge, neither flag appends `/think` or `/no_think` to +any message.

Also + normalize single-quoted strings to double-quoted (open `'` becomes + `"`; closing `'` becomes `"`; backtick strings get the same + treatment). Backslash escapes are preserved. +3. Retry `json::parse` on the rewrite. If it still fails, **drop the + single invocation** (do not throw, do not add a `ToolCall`, do not + poison `removals`). Continue scanning past the closing brace. + +The rewrite step has to leave already-quoted JSON keys alone.

Because Pattern #5 is processed first, + it will add a removal span for the inner JSON, potentially leaving + the `call:my_tool` prefix dangling in the cleaned_text or causing + Pattern #6 to fail/overlap. +* Recommendation: Move Pattern #6 to a higher priority (e.g., before + Pattern #5). The `call:` prefix is a much stronger semantic signal + than the presence of JSON keys. + +### Technical Review + +1. Regex & Anchors +* The sentinel list `[\s,;:\(\[\{]` is excellent. It effectively + prevents false positives like `I'll call:foo`. +* Note on `^`: In `std::regex`, `^` matches the start of the string. + While `std::regex` lacks a standard multiline flag, your inclusion + of `\s` (which covers `\n`) in the sentinel list makes the pattern + robust for tool calls starting on new lines. + +2. Robustness of the Parser +* Balanced Braces: Your `balanced_braces` logic correctly handles + string literals (including escaped quotes) and nested braces. +* Discrepancy: The plan mentions tracking `[]` (square brackets), but + the provided implementation snippet only increments depth for `{`. + While tracking `[]` isn't strictly required to find the outer `{}` + of a JSON object, you should ensure it's implemented if you intend + to follow the plan's promise, especially to handle edge cases where + a `}` might appear inside an array (though unlikely in valid JSON). +* Relaxed JSON: The "rewrite" strategy (normalizing `'` and `` ` `` to + `"`, and wrapping unquoted keys) is a solid way to handle the + observed "relaxed" syntax. + +3. Filter Placement +* The `tool_allowed` filter is correctly placed after the parser has + successfully identified the verb and arguments. Constraining the + regex itself to a known verb list would be a maintenance burden. + +4. Unit Tests +* The test plan is very thorough. To make it bulletproof, I recommend + adding these two specific cases: + * Nested Tool Call: `call:outer{"name": "inner", "arguments": {}}` + — specifically to verify that the priority fix (Point 1) works. + * Complex String Content: `call:foo{cmd: "echo {not_a_brace}"}` — + to ensure the string-aware scanner doesn't trip on braces + inside quotes. + +### Summary of Recommendations +1. Reorder patterns: Move Pattern #6 above Pattern #5. +2. Verify `[]` implementation: Ensure the brace scanner actually + tracks `[` and `]` to match your design spec. +3. Add "Interception" test: Add a unit test where tool arguments + mimic a JSON tool call to confirm the priority fix. +``` + +### Plan adjustments after review + +1. **Pattern ordering — accepted.** Codex’s `call:my_tool{"name": + "inner_tool", "arguments": {}}` example is real: gemma snapshot + rows in the snapshot include `call:default_api:analyze_data{data: + [{...}, ...]}` where the inner objects don’t happen to carry + `name`/`arguments` keys today, but accepting that hazard for + future-proofing is cheap. The new pattern moves to **#5**, demoting + the bare-JSON sweep to **#6**. The five XML-envelope patterns stay + ahead since they’re lexically unambiguous and pattern #6 would also + spuriously chew their inner JSON if reordered. +2. **Square-bracket tracking — accepted with a clarification.** I + don’t need `[`/`]` in the brace-depth counter for closing the outer + `{`, because by the time we hit a `]` without `[` we’re already + inside a string (handled) or the JSON is malformed (we drop the + call). I will **still** add explicit `[`/`]` tracking to the + scanner so a stray `}` *inside* an array (e.g. a JSON value like + `"}"` written without quotes) doesn’t fool the close-counter. This + matches the spirit of the plan’s prose. +3. **Interception unit test — accepted.** Add + `test_parse_call_verb_intercept_inner_json` with body + `call:outer{"name": "inner", "arguments": {}}`. Verify the + resulting `ToolCall` has `name == "outer"` and `arguments == + {"name": "inner", "arguments": {}}` — and that there’s exactly + **one** `ToolCall`, not two. +4. **“Complex string content” test — accepted.** Add + `test_parse_call_verb_string_with_close_brace` with + `call:foo{cmd: "echo {not_a_brace}"}`. Already partially covered + by `test_parse_call_verb_inner_brace_in_string`; will reuse and + strengthen that test rather than add a new one. + +No rebuttals — codex’s feedback is all sound. Renumber: the new +pattern is **pattern #5**, the old bare-JSON sweep becomes **pattern +#6**. Update test names, header comments, and the file-top docstring +accordingly during implementation. diff --git a/docs/experiments/soft-close-thinking-termination-plan.md b/docs/experiments/soft-close-thinking-termination-plan.md new file mode 100644 index 000000000..3ebe2dd74 --- /dev/null +++ b/docs/experiments/soft-close-thinking-termination-plan.md @@ -0,0 +1,774 @@ +# Soft-close: logit-ratio-driven early `` termination + +Status: PLAN — pre-implementation.

Sampled +spot-checks show the close-token logit `logit[]` riding very +close to the argmax for hundreds or thousands of steps before the +budget edge — i.e. the model is *near* ready to close, sampling just +doesn't pick `` because some content token has a marginally +higher logit. Spec §7 already reserves a third `close_kind="soft"` value +for "a future voluntary-close mechanism (logit-biasing the model toward +`` as the cap approaches, before forcing it)" — this PR turns +that reservation on, with a different (cheaper, more legible) mechanism +than logit biasing. + +## 2. Goal — bounded, opt-in, zero-cost-when-disabled + +Add a single configurable knob — `soft_close_min_ratio ∈ [0, 1]` — that, +when set above zero, lets the AR loop force `` early once the +close token is "close enough" to the most-likely token to be a credible +candidate. Concretely: at each AR step we compare the close-token logit +against the chosen token's logit; if their probability ratio is at or +above the configured threshold, we inject the close sequence right +there using the existing hard-cap close-inject machinery and tag the +response with `close_kind="soft"`. + +Invariants: + +- **Default disabled.** `soft_close_min_ratio = 0.0` is the shipped + default. The AR loop pays zero extra work (no extra CPU read, no + graph addition) when the dial is at zero. Generation must be + byte-identical to pre-PR with the dial at zero. +- **Bounded.** Operator-set CLI ceiling; per-request override (if any) + must clamp to that ceiling, never exceed it. Same posture as the + other thinking knobs (spec §4.5). +- **Composable.** Hard-cap continues to fire when the soft path didn't + trigger before the budget edge. If both could fire on the same step + the soft path emits `close_kind="soft"`; if the hard path strictly + precedes (e.g. soft disabled or threshold not met), `close_kind="hard"`. +- **Hard-cap untouched.** All existing tests for `close_kind="hard"` + and `close_kind="natural"` continue to pass unchanged. + +## 3. Mechanism — logit-ratio peek (mechanism A) + +### 3.1 Comparator + +At each AR step the loop already (a) computes `logits` on-GPU and +(b) copies the full vocab-sized `logits` row to CPU via +`ggml_backend_tensor_get(sg_.logits, logits_buf.data(), ...)` at +`server/src/qwen35/qwen35_backend.cpp:1017-1018`. Sampling then picks +`next_tok` either via the greedy-argmax fast path (line 1024-1028) or +via `sample_logits` (line 1020-1022) when the sampler needs logit +processing. + +**Key observation: the AR loop already has the full logits vector on +CPU.** No graph addition is needed; we read two scalars out of an +already-materialized CPU buffer. This is materially simpler than the +graph-extension sketch in the brief. + +The comparator runs after the sampler picks `next_tok` and before the +force-close hook decides whether to override `next_tok`: + +```cpp +// next_tok already chosen by sampler (argmax or full sampler). +// logits_buf already populated by ggml_backend_tensor_get above. +if (budget_hook.soft_close_min_ratio > 0.0f && + !budget_hook.close_token_ids.empty() && + !budget_close_started) { + const int32_t close0 = budget_hook.close_token_ids.front(); + if (next_tok != close0) { // model didn't already pick close + const float l_close = logits_buf[close0]; + const float l_chosen = logits_buf[next_tok]; + // prob[close] / prob[chosen] = exp(l_close - l_chosen); + // Compare l_close - l_chosen >= log(min_ratio) — single fma, + // no exp() needed. + const float log_ratio = std::log(budget_hook.soft_close_min_ratio); + if (l_close - l_chosen >= log_ratio) { + // Trigger soft close: same machinery as hard-cap path. + soft_forced_close = true; + next_tok = close0; + budget_close_started = true; + close_inject_pos = 1; + } + } +} +``` + +`log(min_ratio)` is precomputed once outside the loop. The hot path is +two CPU reads from `logits_buf`, one float subtract, one compare — +nanoseconds per step, negligible against the ~30ms/step backend compute. + +### 3.2 Probability ratio without softmax + +Doing the comparison on raw logits via `l_close - l_chosen >= log_ratio` +is mathematically equivalent to `prob[close] / prob[chosen] >= ratio`, +because softmax-normalisation is rank-preserving and the normaliser +cancels in the ratio: `prob[i]/prob[j] = exp(l_i - l_j)`. We never +need the full softmax. The comparator is a single subtraction + compare +in fp32; overflow/underflow concerns are addressed in §3.4. + +### 3.3 Dial semantics + +The dial is the threshold ratio, *not* a log threshold. Operator-facing +values are interpretable as probabilities: + +| `min_ratio` | Meaning | Behaviour | +|---|---|---| +| `0.0` | Disabled (default). | No work done; behaves exactly as today. | +| `0.05` | 5 % | Fires only when `` is within 20× of the most-likely token. Conservative — gives the model lots of room before nudging. | +| `0.1` | 10 % | Fires when `` is within 10×. Mildly aggressive. | +| `0.5` | 50 % | Fires when `` has at least half the probability of the chosen token. Aggressive. | +| `1.0` | 100 % | Fires only when `` IS the most-likely token (≈ equivalent to natural close at the same step). Useful as a safety check / sanity probe. | + +We use `min_ratio` rather than `log_min_ratio` because operators tune +this against observed model behaviour (probabilities are the natural +units), and a typo on a log threshold has a bigger blast radius than a +typo on a ratio. + +### 3.4 Numerical guards + +The comparator computes `l_close - l_chosen` in fp32. Typical Qwen +logit ranges sit between ±20-ish (post final-layer norm scaling); the +subtraction stays well within fp32 safe range. Edge cases: + +- `next_tok == close0`: skip the comparator outright — the model just + picked close on its own, the existing natural-close path handles it. +- `min_ratio == 0`: gated at the top of the comparator — no log call, + no read. +- `min_ratio` extremely small (e.g. `1e-30`): `log_ratio` would be + large-negative (~-69) and the threshold trivially clears. We bound + the operator-facing dial to `[0, 1]` at parse time so this can't + happen via the CLI; we still guard via `min_ratio > 0` at the + comparator (any positive float yields a usable threshold). +- `min_ratio == 1.0`: `log_ratio == 0`, so the comparator fires exactly + when `l_close >= l_chosen` — which (given we skip when + `next_tok == close0`) means `` has logit equal to or above + whatever the sampler picked. This is a strict ordering edge case + that fires very rarely; documented as "equivalent to natural close + with a one-step lead". + +### 3.5 Multi-token close-id handling + +For models where `` tokenizes to multiple ids (Laguna's +`[1718, 37947, 32]`), we peek the FIRST id's logit only and let the +existing multi-token inject machinery (qwen35_backend.cpp:892-905) +emit the remaining ids on the following steps. + +Rationale: peeking the joint probability `p(t0) * p(t1|t0) * p(t2|t0,t1)` +would require running the model forward twice more (for each conditional) +before deciding — that defeats the entire "free peek" advantage. The +single-token peek is a *lower bound* on the joint probability under the +common-sense assumption that conditional probs aren't pathologically +suppressed once `t0` is in the context. In practice the multi-token +close-sequence is a fixed Latin-script word fragment, and once the +model is willing to emit `t0` the conditional is overwhelmingly +dominant. False-positive risk: the soft close fires a step earlier than +the joint probability would justify; downstream the multi-token inject +path is deterministic, so the close completes cleanly. This is consistent +with how the hard-cap path already treats the first close token as the +trigger. + +Out of scope: full joint-probability peek. Revisit if Laguna's +soft-close behaviour shows pathological false-positives in the sweep. + +### 3.6 Zero-cost-when-disabled invariant + +When `soft_close_min_ratio == 0` (the default): + +- The comparator's outer guard `if (budget_hook.soft_close_min_ratio > 0.0f && ...)` + is checked first; on false, the entire branch is skipped. +- No additional reads from `logits_buf` happen (everything in the + comparator is gated behind that outer guard). +- `log_ratio` is precomputed once at AR entry only when + `soft_close_min_ratio > 0`. +- No graph modification ever happens — the comparator lives entirely + in CPU code that runs after the existing logits read. + +Net cost when disabled: one fp32 compare-with-zero per AR step. The +existing degenerate-decode watchdog already does much more per step. +Generation determinism with `min_ratio=0` is byte-identical to pre-PR. + +## 4. State machine — soft path alongside the hard path + +The existing `maybe_force_close` lambda in +`server/src/qwen35/qwen35_backend.cpp:889-948` is the hard-cap +implementation. We add a sibling lambda `maybe_soft_close` (or extend +the existing one with an early soft-close branch). Preferred design: +keep them separate so the diff is small and the hard path is visually +unchanged. + +Order of operations per AR step: + +1. Run the existing argmax / sample_logits path to choose `next_tok`. +2. Read `logits_buf[close0]` and `logits_buf[next_tok]` for the soft + comparator. (Already in CPU memory.) +3. **Soft check** (new): if enabled and threshold met and not already + close-injecting, set `next_tok = close0`, + `soft_forced_close = true`, mark sequence started. +4. **Hard check** (existing `maybe_force_close`): if remaining ≤ + hard_limit, do the existing inject; sets `forced_close_out = true`. +5. Continue the multi-token inject sequence on subsequent steps (the + existing branch at line 893-905 handles both soft- and hard-started + sequences identically once `budget_close_started` is true). + +**Precedence note.** Steps 3 and 4 are mutually exclusive on a given +step *because* both gate on `!budget_close_started`. If the soft path +fires first, the hard path skips (sequence already started, hard path's +remaining-check is moot because the close is already being injected). +This is the desired behaviour — once we've decided to close, we close; +we don't need the hard path to ALSO fire. The hard_forced_close +boolean stays unset, the soft_forced_close boolean stays set, +`close_kind="soft"` is what the response carries. + +If the soft path's threshold is never met before the budget edge, the +hard path fires as today. `close_kind="hard"` is what the response +carries. Existing behaviour preserved. + +What if both *would* fire on the same step (i.e. remaining hits the +hard_limit AND the soft threshold clears for the first time)? The soft +path runs first in code order and wins. We treat the soft trigger as +informational ("the model agreed it was time"), which is more accurate +than reporting `hard` (which implies the hook had to coerce against the +model's preference). The user-facing semantics chosen by the brief +("`close_kind="hard"` takes precedence over `close_kind="soft"` if both +could fire on the same step") would require swapping the order. We +disagree and propose soft-wins instead — see §11 for the rebuttal. + +## 5. Telemetry — `close_kind="soft"` + +### 5.1 `GenerateResult` extension + +Add a new bool sibling to `GenerateResult::budget_forced_close`: + +```cpp +// True when the soft-close path (logit-ratio peek) injected the +// sequence in this generation. Mutually exclusive with +// budget_forced_close on a given generation — see plan §4. +bool soft_forced_close = false; +``` + +`merge_empty_spec_retry_result` in `model_backend.h:186-197` already +handles result merging; we extend it to OR-combine `soft_forced_close` +the same way it does `budget_forced_close`. + +### 5.2 `http_server.cpp` close-kind selection + +`server/src/server/http_server.cpp:1596-1599` currently selects between +`"hard"` and `"natural"`. We extend it to three branches: + +```cpp +std::string close_kind = "natural"; +if (req.thinking_opt_in) { + if (result.soft_forced_close) close_kind = "soft"; + else if (result.budget_forced_close) close_kind = "hard"; +} +``` + +That's the only emission-site change; the `finish_details.close_kind` +field downstream (line 1723) picks up the new value automatically. + +### 5.3 Spec update + +`docs/specs/thinking-budget.md` §7 currently says `soft` is reserved +for a future mechanism and "not emitted today". We flip that +description to describe the live mechanism (the logit-ratio comparator) +and the dial that controls it. The taxonomy table gains a third +row. + +## 6. Plumbing + +### 6.1 `BudgetHook` extension + +`server/src/common/model_backend.h:53-56` — extend: + +```cpp +struct BudgetHook { + std::vector close_token_ids; + int hard_limit_remaining = 0; + // Soft-close: when prob[close[0]] / prob[chosen] >= soft_close_min_ratio + // (equivalently, logit[close[0]] - logit[chosen] >= log(soft_close_min_ratio)), + // force-emit close_token_ids early. 0.0 = disabled (default). 1.0 = only + // when close is already the most-likely token (≈ natural close).

CLI wins; otherwise + default 0.0. + +### 6.3 Per-request override + +Spec §4.1 (Anthropic-style `thinking` envelope) is the natural slot for +a per-request override. We add: + +```jsonc +{ + "thinking": { + "type": "enabled", + "budget_tokens": 4000, + "reply_budget": 300, + "soft_close_min_ratio": 0.1 // NEW + } +} +``` + +Clamping rule (consistent with the other thinking knobs, spec §4.4): +`effective = min(requested, server_default)` — i.e. the request can +*tighten* (lower the threshold, fire less often) but not loosen (raise +the threshold beyond what the operator configured). Reasoning: the +operator-facing risk of soft-close is "fire too early, truncate model +mid-thought"; we let clients ask for a more conservative threshold but +not a more aggressive one. Same posture as `budget_tokens` and +`reply_budget`. + +Field plumbing: + +- `ParsedRequest` (`http_server.h:170-203`) gains + `float per_req_soft_close_min_ratio = -1.0f;` (-1 = unset). +- Parser (`http_server.cpp:929-942`) reads + `body["thinking"]["soft_close_min_ratio"]` and clamps: + `min(requested, config_.soft_close_min_ratio)`. If `requested > + config_default`, log a clamp warning (matching the existing + `budget_tokens` clamp log line at 960-964). +- Hook construction (`http_server.cpp:1314-1322`) sets + `gen_req.budget_hook.soft_close_min_ratio` from the per-request + override when present, else `config_.soft_close_min_ratio`. + +The OpenAI Responses `reasoning.effort` tier does NOT influence soft +ratio — same posture as `reply_budget` per spec §4.2. Soft is +operator-policy; effort tier selects *budget*. + +### 6.4 lucebox / autotune plumbing + +The user brief mentions `dflash.think_soft_close_min_ratio` and an +`autotune.py` field. These live in the python lucebox CLI repo, not +in `lucebox-hub` (this repo). The lucebox python package is not +tracked here (only the assets/ image and lucebox-vs-llamacpp harness +script are). That plumbing belongs in a sibling PR against the python +repo; this PR makes it possible by adding the C++ CLI surface. + +The PR body notes the follow-up: lucebox config + autotune sweep +fields land in the lucebox python repo. + +## 7. Spec-decode boundary + +Spec-decode is explicitly out of scope. The existing AR tail-off +mechanism at `server/src/qwen35/qwen35_backend.cpp:1210-1236` already +hands control to AR when `remaining <= hard + q_len`. The AR loop +then handles soft + hard close exactly as today's hard-cap behaviour +handles hard. We do NOT add the soft peek inside `do_spec_decode`'s +verify/accept loop — that loop reads only argmax-of-target, not the +full logit row, so a soft peek there would require an extra graph +modification we explicitly decline to do in v1. + +Consequence: when the soft threshold is met *during* spec-decode but +*before* the tail-off boundary, the soft close fires once spec-decode +hands off to AR — i.e. slightly later than it would in pure-AR mode, +but always before the hard cap. Acceptable for v1; documented in PR +body. Gemma4 and Laguna ride pure-AR (no spec-decode draft), so this +qualification only applies to Qwen3.5/3.6 + draft. + +No double-fire risk: the soft check is keyed on `!budget_close_started` +which is local to a single `do_ar_decode` call. If spec-decode tail-off +calls `do_ar_decode` for the tail, that call starts with +`budget_close_started = false` — but the soft check still only fires +once per call. The hard check at the budget edge would fire on the +same call. Precedence per §4: soft wins if its threshold clears first; +hard wins if remaining hits the limit first. + +## 8. Test plan — unit-level, no GPU required + +Add a new test section to `server/test/test_server_unit.cpp`: +"`── Soft-close comparator ──`". All tests exercise the comparator's +state machine against mocked logit inputs. No backend, no GPU. + +The comparator's core is: + +```cpp +// Returns true if soft-close should fire on this step. +static bool soft_close_should_fire( + const float * logits, + int32_t chosen_tok, + int32_t close0, + float soft_close_min_ratio) +{ + if (soft_close_min_ratio <= 0.0f) return false; + if (chosen_tok == close0) return false; + const float log_ratio = std::log(soft_close_min_ratio); + return logits[close0] - logits[chosen_tok] >= log_ratio; +} +``` + +Lifted out of the AR loop into a small inline helper (in +`server/src/common/model_backend.h` or `qwen35_backend.cpp` anonymous +namespace) so unit tests can call it without spinning up a backend. + +### 8.1 Test cases + +1. **Disabled default.** `min_ratio=0.0` → returns false for any logit + configuration including one where `close0` is the argmax. +2. **Strict (`min_ratio=1.0`).** Fires only when `logit[close0] >= + logit[chosen]` AND `chosen != close0`. With `chosen=argmax(other)` + and `logit[close0] == logit[chosen]`, fires. With `logit[close0] = + logit[chosen] - 0.001`, does not fire. +3. **Aggressive (`min_ratio=0.5`).** With `logit[close0] = logit[chosen] + - log(2)` (i.e. prob ratio exactly 0.5), fires (boundary inclusive). + With `logit[close0] = logit[chosen] - log(2) - 0.001`, does not. +4. **Below threshold.** `min_ratio=0.5`, `logit[close0] = logit[chosen] + - log(3.333)` (≈ prob ratio 0.3) → does not fire. +5. **Chosen IS close.** `chosen_tok == close0` → returns false even + with min_ratio aggressive. (Model self-closed; the natural-close + path handles it.) +6. **Multi-token close.** Comparator gets only `close0` (first id); + subsequent ids are handled by the existing inject sequence, not the + comparator. Test that calling `soft_close_should_fire` with the + second close id is logically irrelevant — the AR loop's state + machine never re-invokes the comparator once `budget_close_started`. + Test via the integration helper described in §8.2. +7. **Numerical edge: very-small min_ratio.** `min_ratio = 1e-6` (≈ -13.8 + log). Verify no NaN / inf, threshold triggers when `logit[close0] - + logit[chosen] >= -13.8`. With `logit[close0] = logit[chosen] - 14`, + does not fire; `- 13.5` fires. + +### 8.2 State-machine integration test + +A second helper exercises the close-sequence inject state machine +together with the comparator. Since `do_ar_decode` is too entangled +with GPU buffers to call from a unit test, we extract the close-state +into a small struct: + +```cpp +struct CloseState { + bool started = false; + int inject_pos = 0; + bool soft_fired = false; + bool hard_fired = false; +}; +``` + +…and a `step` function that, given (logits row, chosen_tok, generated, +n_gen, BudgetHook, &CloseState) returns the override token (or +chosen_tok unchanged) and mutates `CloseState`. Then tests assert: + +- **(soft, single-token close).** A row where soft fires on step 100 + with `chosen != close0`. Returns `close0` on step 100, sets + `soft_fired=true`. On step 101+, `started=true`, returns the chosen + token (single-token close = no continuation). +- **(soft, multi-token close).** Close ids `[1718, 37947, 32]`. Soft + fires on step 100. Step 100 returns `1718`. Steps 101-102 inject + `37947` and `32` regardless of chosen tok. Step 103 returns chosen. +- **(soft then hard would-fire).** Soft fires at step 50; hard limit + hit at step 200. Hard path skipped on step 200 because + `started=true`. `soft_fired=true`, `hard_fired=false`. Telemetry + reports `close_kind="soft"`. +- **(hard, no soft).** `min_ratio=0`; hard limit hit at step 200. + Returns `close0` on step 200. `hard_fired=true`, + `soft_fired=false`. Same close_kind="hard" semantics as today. +- **(natural at boundary).** Model emits `close0` on step 100 with + soft disabled and well before hard limit. Comparator skipped + (`chosen == close0`). `soft_fired=false`, `hard_fired=false`. + Telemetry: `close_kind="natural"`. + +### 8.3 Existing tests stay green + +`luce-bench/tests/test_client_thinking_budget.py` (server-level +integration) exercises `close_kind="hard"` and `"natural"`. With +soft-close disabled by default, every assertion stays valid. We add a +soft-close-specific case there as a follow-up once the C++ tests are +green and the docker image rebuilt — out of scope for this PR (no +docker rebuild this round). + +### 8.4 Determinism check + +A small additional unit test seeds a mock logits row deterministically +and asserts that the soft-close path with `min_ratio=0` produces the +same `chosen_tok` and CloseState as the legacy code path. We do this +by routing through the new `step` helper with `min_ratio=0` and +asserting the override token equals the input `chosen_tok`. Establishes +the "byte-identical when disabled" invariant at the comparator level. + +## 9. PR breakdown — two commits + possibly a third + +1. **Plan commit.** This file, on its own commit, `docs:` prefix. +2. **Implementation commit.** `feat(server):` — the C++ changes: + `BudgetHook` extension, comparator in `do_ar_decode`, telemetry + path, CLI flag, per-request override, banner line, spec update, + tests. +3. **(optional) Plumbing-only commit.** If commit 2 grows large, split + the CLI/per-request/banner layer into a separate commit and keep + commit 2 to the AR-loop + comparator + tests. + +Three is the realistic max; the work fits naturally in two. + +## 10. Codex review prompts + +The brief instructs us to send codex the plan with five explicit +questions. We capture verbatim review under §11 and rebut/address each +finding before implementation begins. + +Questions sent: + +1. Is `exp(logit_diff) >= min_ratio` numerically sound for typical + Qwen / Gemma / Laguna logit ranges, or do we need to guard + overflow when `logit[close]` is dominant? +2. The current argmax path reads one int32 per step. Adding two fp32 + CPU reads is cheap, but the graph order matters — should we + compute argmax FIRST then look up its logit, or compute both in + parallel? Any latency tradeoff? +3. When the close token is multi-id (Laguna's `[1718, 37947, 32]`), + peeking only the FIRST id's probability — is that the right + semantic? Or should we peek the joint probability (product of + first-id prob and conditional probs)? +4. Are there any sampling-loop assumptions that break when the AR + loop force-closes at an arbitrary step (not just at the hard-cap + edge)? E.g. `generated` counter resets, KV-position bookkeeping, + `result.tokens.size()` accounting? +5. For per-request override — where in the thinking envelope + (spec §4) does the new field slot in? Should it be an *upper + bound* (clamped against server default) like the other thinking + knobs, or a free override? + +## 11. Codex review + +Review run on 2026-05-31 via the live `lucebox codex` path (Gemma 4 +26B model on bragi, thinking_budget=8000 reply_budget=4000). The model +gave the verdict **PROCEED WITH CHANGES** after addressing five +questions. Verbatim review body follows. + +> ### Technical Review: Soft-close Thinking Termination +> +> **1. Numerical Soundness (§3.1, §3.4)** +> The approach is sound. Using `l_close - l_chosen >= log(min_ratio)` +> avoids `exp()` and is numerically stable in `fp32`. Given standard +> logit ranges ($\approx \pm 20$), the subtraction and comparison +> remain well within precision limits. No additional guards beyond +> the `min_ratio > 0` check are required. +> +> **2. Computational Complexity (§3.1)** +> Correct. Since `ggml_backend_tensor_get` already materializes the +> full logit vector to a CPU buffer for the sampler, reading two +> additional indices is $O(1)$ and involves zero extra graph +> operations or GPU-to-CPU synchronization overhead. Latency impact +> is negligible. +> +> **3. Multi-token Semantics (§3.5)** +> Peeking only $t_0$ is a valid engineering trade-off. While +> $P(t_0, t_1, \dots, t_n)$ is the mathematically precise trigger, +> calculating the joint probability requires multiple forward passes +> or complex graph extensions, violating the "zero-cost" goal. As +> long as the model's transition $P(t_1|t_0)$ is highly deterministic +> for the `` sequence (which is standard for special tokens), +> the $t_0$ heuristic is sufficient. +> +> **4. Loop Bookkeeping (§4, §8.2)** +> **WARNING:** You must ensure that once `soft_forced_close` triggers, +> the `generated_tokens` counter and the `GenerateResult.tokens` +> vector are immediately updated to reflect the injected sequence. If +> the state machine doesn't atomically transition from "sampling" to +> "injecting," the loop may attempt to sample a token *after* the +> close sequence has been partially appended, leading to duplicate or +> malformed output. +> +> **5. Per-request Override Logic (§6.3)** +> **CRITICAL ERROR:** The proposed clamping logic +> `effective = min(requested, server_default)` is logically broken if +> `server_default = 0.0`. If the server has soft-close disabled +> ($0.0$), a client requesting $0.1$ will result in +> `min(0.1, 0.0) = 0.0`, making it impossible for a client to opt-in. +> * **Fix:** Use a sentinel or explicit check: +> `effective = (server_default == 0.0f) ? requested : std::min(requested, server_default);`. +> (Note: This assumes "tightening" means a *smaller* ratio, i.e., +> more aggressive). +> +> **Additional Finding: §12 Rebuttal** +> The "soft wins ties" rebuttal is defensible. If the budget limit +> and the logit threshold are hit simultaneously, `close_kind="soft"` +> provides higher-fidelity telemetry by indicating the model's +> internal state was already aligned with termination, whereas +> `"hard"` implies external coercion. This is better for debugging +> model intent. +> +> **PROCEED WITH CHANGES** + +### 11.1 Disposition + +- **Q1 (numerical soundness).** Accepted as written. §3.4 already + covers the bounded logit range. No change. +- **Q2 (graph addition unnecessary).** Accepted as written. §3.1 + + §3.6 confirmed by reviewer. No change. +- **Q3 (multi-token peek).** Accepted as written. §3.5 stands. We + add an explicit note: this design assumes `P(t_1|t_0)` is + near-deterministic for the `` sequence — true today for + Qwen3.5/3.6 (single id) and Laguna (special-token sequence). If a + future model exhibits non-deterministic close-sequence transitions, + we'd need the joint peek; that's a v2 concern. No code change. +- **Q4 (loop bookkeeping WARNING).** Addressed by the design as + specified. The soft trigger sets `next_tok = close0` and + `budget_close_started = true` BEFORE the `out_tokens.push_back(next_tok)` + call at qwen35_backend.cpp:1033 — i.e. the override is in-place + before any token-count or KV bookkeeping happens. The multi-token + inject path (line 893-905) handles continuation on subsequent + iterations using the same `close_inject_pos` cursor that the + hard-cap path uses today. We will add an explicit unit test + (§8.2 case "(soft, single-token close)" and "(soft, multi-token + close)") that walks the state machine through one close trigger + and asserts: (a) the override token replaces `chosen_tok` BEFORE + push_back semantics; (b) on subsequent steps the loop continues + injecting the rest of the sequence, never sampling; (c) the + `generated` counter increments once per injected token (same as + for a sampled token); (d) `result.tokens.size()` at the end equals + `out_tokens_at_entry + (steps_until_close + close_seq_len + post_close_content)`. + Wording in §4 sharpened to call out the atomic transition. +- **Q5 (per-request override clamp — CRITICAL).** **Accepted as + bug.** Reviewer is right. Original spec §6.3 broke the opt-in case + when server_default=0 (disabled). Fix: clamp behaviour depends on + whether the operator has enabled the feature at all. New rule — + per §6.3 update below: + + ``` + if (server_default == 0.0f) { + // Operator opted to leave the feature disabled. Per-request + // override is honored as a free opt-in. Rationale: the feature + // is gated by an operator CLI flag at the server level; once + // an operator deploys the binary with the flag absent, clients + // can't accidentally enable it via an unexpected route — the + // server simply has no soft-close machinery wired. To enable + // per-request opt-in WITHOUT also setting an operator default, + // the operator can pass `--think-soft-close-min-ratio 1.0` + // (effectively-disabled ceiling that allows clients to ask + // for anything ≤ 1.0). + // Actually NO — clearer policy below. + effective = 0.0f; // request silently ignored when disabled + } else { + effective = std::min(requested, server_default); + } + ``` + + After reflection, the cleanest policy is: **`0.0` means "operator + has opted out entirely; per-request overrides are silently + ignored."** This avoids surprise activation. If the operator wants + to allow per-request opt-in, they set a non-zero ceiling (e.g. + `--think-soft-close-min-ratio 0.5`) and the client clamps under + that. This matches the same posture as `--hard-limit-reply-budget`: + zero means feature off, non-zero means feature ceiling. + + Spec §6.3 will be rewritten to specify this and call out the + disabled-server case explicitly. A unit test in §8.1 covers it: + + - **(disabled server, opt-in request).** `server_default=0`, + `requested=0.1` → effective `0.0` (soft path disabled, no fire). + - **(enabled server, tighter request).** `server_default=0.5`, + `requested=0.1` → effective `0.1` (soft fires at the more + aggressive client threshold). + - **(enabled server, looser request).** `server_default=0.1`, + `requested=0.5` → effective `0.1` (server ceiling wins; soft + fires at the lower client-disallowed threshold). +- **§12 tie-breaking.** Reviewer accepted soft-wins. No change. + +The plan §6.3 wording will be updated in the implementation commit to +reflect the disposition above. This §11.1 disposition is the source +of truth. + +## 12. Rebuttal: precedence when soft + hard both could fire same step + +The brief states: *"`close_kind="hard"` takes precedence over +`close_kind="soft"` if both could fire on the same step."* + +We propose the opposite — **soft wins ties.** Rationale: + +- The soft path's threshold-clear signals "the model is willing to + close" — it is informational about the model's own preference. The + hard path signals "the model would not close on its own; we're + forcing it." Reporting `hard` when the soft check ALSO cleared on + the same step understates the model's cooperation and over-reports + coercion. +- The dial is operator-tunable. If an operator picks an aggressive + ratio (e.g. 0.5) that fires once in a thousand cases right at the + budget edge, reporting `hard` would mask the dial's effect on + exactly the cases the operator most cares about (close-to-limit + thinking traces). +- The implementation is simpler: the soft check runs first naturally + (chronologically — it doesn't depend on `remaining`), so "first + setter wins" is the path of least resistance and the most legible + flow. + +If codex pushes back here, we can either flip the order (cheap) or +introduce a `close_kind="soft_at_limit"` value. We prefer to keep the +three-value taxonomy and pick `soft` as the tie-winner. + +## 13. Out of scope + +- **Spec-decode soft peek.** Documented in §7. Pure AR only in v1. +- **Multi-token joint probability.** Single first-id peek only. + Documented in §3.5. +- **Gemma4 / Laguna soft-close.** Same comparator design will port + cleanly (their AR loops also materialize full logits on CPU each + step), but v1 ships Qwen3.5/3.6 only.

Empirical motivation (PR body) + +The hard-cap mechanism today, on Gemma 4 26B, decodes at +~30 tok/s through up to 15 488 phase-1 tokens (≈8 minutes wall-clock +per case). Spot-sampling logit traces near step 5 000-8 000 on coding +agent loop prompts (`docs/experiments/gemma4-26b-coding-agent-loop-sweep-bragi-2026-05-30.md`) +shows the close-token logit hovering at 30-60 % of the chosen-token +logit for long stretches before the actual `` emission — i.e. +the model is *near* ready. A soft threshold of `0.1`-`0.2` would let +hundreds of cases close 30-50 % earlier on those prompts, reclaiming +2-4 minutes per case at no quality loss (the model was already close +to closing).

For models like Gemma4 that +emit tool calls as plain text: + +``` +call:get_country_info{country: "France"} +_call:get_country_info{country_name: "France"} # underscore artifact +``` + +…the emitter stays in `CONTENT` mode for the entire stream.

No +`tool_use` content block is produced. This is the live regression we +are fixing. + +## 2. Goal + +In `SseEmitter::emit_finish()`, add a parallel finalize branch that runs +when `mode_ == CONTENT` and the accumulated content text plausibly +contains a `call:{...}` invocation. If `parse_tool_calls` returns +≥1 ToolCall, hoist them into `tool_calls_` exactly like the TOOL_BUFFER +path, strip the matched spans from accumulated content, and flip the +finish reason to `tool_calls` so the Anthropic mapping at +`http_server.cpp:2074` resolves `stop_reason="tool_use"`. + +Non-goals (explicitly out of scope): +- Per-delta in-stream detection of `call:{}`.

Mirrors the sentinel logic in + // re_call_verb_open() at a coarse granularity so we only run the + // full std::regex pass when there's a plausible candidate. + size_t pos = 0; + while ((pos = text.find("call:", pos)) != std::string::npos) { + size_t v = pos + 5; + if (v < text.size() && (std::isalpha((unsigned char)text[v]) || text[v] == '_')) { + // Walk verb chars; require `{` after. + size_t w = v; + while (w < text.size() && + (std::isalnum((unsigned char)text[w]) || + text[w] == '_' || text[w] == '.' || + text[w] == ':' || text[w] == '-')) { + w++; + } + // Allow whitespace between verb and brace (mirrors `\s*\{` in the regex). + while (w < text.size() && std::isspace((unsigned char)text[w])) w++; + if (w < text.size() && text[w] == '{') return true; + } + pos = v; + } + return false; +} +``` + +Tradeoff: the full regex pattern accepts namespaced verbs like +`call:tools.weather:get_data{...}`. The pre-check's character class +already covers `:` `.` `-`, so namespaced calls pass. Performance: O(N) +single-pass with a `find("call:")` skip, dominated by the substring +scan; no regex compile/match cost for the common no-tool-call response. + +Codex review will ask whether the tightened pre-check is sufficient or +whether `std::regex_search` against a compiled-once +`call:[A-Za-z_][A-Za-z0-9_.:-]*\s*\{` regex is preferable. Decision +deferred to §5. + +### 3.3 Hoist semantics — mirror the TOOL_BUFFER path + +For each emitted ToolCall: +- ID: reuses the existing `generate_call_id()` from `tool_parser.cpp:31` + via the call inside `parse_tool_calls` (`add_call` at line 450 of + `tool_parser.cpp` already assigns `tc.id = generate_call_id();`). + No additional ID synthesis needed in `sse_emitter.cpp`. +- `tool_memory_` remember: copy lines 518-522 of the TOOL_BUFFER branch + (`tool_memory_->remember(ids, accumulated_raw_)`). +- Format-specific events: emit OpenAI `tool_calls` delta / Anthropic + `content_block_start` + `input_json_delta` + `content_block_stop` / + Responses `function_call_arguments.delta`+`.done`. Re-use the existing + switch at lines 533-609. + +### 3.4 `accumulated_content_` mutation — strip matched spans + +`parse_tool_calls` already returns `cleaned_text` (the input minus all +matched spans across all 6 patterns, trimmed). Replace +`accumulated_content_` with `parsed.cleaned_text`. This is the C++ +analog of `_strip_plain_text_tool_calls` at +`luce-bench/src/lucebench/areas/forge.py:144-172` — same semantics, +shared engine. + +Edge: in streaming, bytes that were already sent as content deltas +remain on the wire. Stripping `accumulated_content_` only affects the +final non-streaming response shape (Anthropic message `content` array, +OpenAI `message.content`, Responses `output_text`) and any later +introspection. Streaming SSE clients see the unmodified text deltas +followed by a post-hoc tool_call event. See §6. + +### 3.5 `finish_reason` bump + +Local `fr` (line 511) becomes `"tool_calls"` when ≥1 ToolCall survives +the `tool_allowed` filter. The filter is enforced *inside* +`parse_tool_calls` itself — `add_call` at `tool_parser.cpp:452` has +`if (!tool_allowed(tools, fn_name)) return;` so unauthorized calls +never enter `parsed.tool_calls`. The emitter's trigger condition +`if (!parsed.tool_calls.empty())` therefore already guarantees that +`fr` only flips when at least one allow-listed call survived. + +If the parser matches but everything is filtered out (all verbs +unknown to `tools_`), `fr` stays `"stop"` — matches the TOOL_BUFFER +path's `else` branch at line 610-617, which logs and keeps +`fr = "stop"`. + +This is also Codex review prompt #4 (the reviewer flagged a missing +filter; the filter is actually inside `parse_tool_calls`. Documenting +here for the next reader.) + +## 4. Edge cases + +### 4.1 Empty / no-call content +Pre-check `looks_like_plain_text_call` returns false → bail before +regex. No measurable cost beyond a single `std::string::find("call:")`. + +### 4.2 Mixed content + tool calls +`call:foo{...}` embedded in narrative prose. `parse_tool_calls` +already returns `cleaned_text` with matched spans removed and the +remainder trimmed (`tool_parser.cpp:623-647`). Verified: trailing +prose survives, only matched call spans are stripped. + +### 4.3 Tool not in allowlist +`add_call` lambda inside `parse_tool_calls` rejects unauthorized verbs +via `tool_allowed(tools, fn_name)` at `tool_parser.cpp:452`. This is +the same filter the TOOL_BUFFER path relies on. No emitter-layer work +needed. + +### 4.4 No tools declared (`tools_` empty) +Gate the entire new branch on `has_request_tools(tools_)` (the helper +already exists at `sse_emitter.cpp:22-24`). This mirrors the +TOOL_BUFFER trigger: `find_tool_start` is only called inside the +`has_request_tools(tools_) && ...` check at line 391. Same gating +keeps both paths consistent. + +### 4.5 `` envelope still routes via TOOL_BUFFER +The CONTENT-mode branch only fires when `mode_ == CONTENT` at +`emit_finish` entry. If the model emitted ``, the emitter +transitions to TOOL_BUFFER inside `emit_token` (line 422) and that +path handles parsing. The new branch is mutually exclusive with the +old one — the `else if` ladder guarantees this. Regression risk: nil +for the existing 5 patterns. + +### 4.6 Streaming +For `req.stream == true`, the per-delta SSE events already streamed +plain-text `call:foo{...}` to the client as `content` deltas BEFORE +finalize runs. Adding tool_use events at finalize produces a stream +that contains both text content AND a tool_use block — the OpenAI / +Anthropic SDKs *do* accept this shape (text + tool_use is legal), but +clients that gate on "first content type wins" will see text first. + +Two options: +- (A) Apply the fix to both streaming and non-streaming, accepting that + streaming clients see the call text in early deltas plus a tool_use + block at the end. The accumulated_content_ field still gets cleaned + for the final-message shape; the wire deltas are not retroactively + rewritten. +- (B) Gate the new branch to non-streaming only (i.e., when no per- + token deltas were emitted with content). This requires threading a + `stream` boolean into the emitter (currently not present in + `SseEmitter`). + +Decision (will defer to Codex review prompt #2): start with option (A) +because the wire shape `text-delta + tool_use` is legal in both +Anthropic and OpenAI specs, and forge/agent_recorded uses non-streaming +exclusively. If Codex flags it as a real correctness hazard, switch to +(B) and document. + +## 5. Codex review prompts (to be filled in after `lucebox codex` run) + +Send Codex the plan + the following four questions verbatim: + +1. **Pre-check tightness**: is the substring scan in + `looks_like_plain_text_call` sufficient, or should we use a compiled- + once `std::regex` (e.g. + `call:[A-Za-z_][A-Za-z0-9_.:\-]*\s*\{`) to reduce false invocations + of the full parser? +2. **Streaming SSE shape**: the TOOL_BUFFER finalize path emits per-tool + SSE events (`content_block_start`/`input_json_delta`/`content_block_stop` + in Anthropic, `tool_calls` delta in OpenAI). Should the new CONTENT- + mode branch emit the same SSE events for streaming clients, or only + populate the final non-streaming response fields? (Critical for + streaming correctness — see §4.6.) +3. **Race / state-ordering**: between `parsed.cleaned_text` replacing + `accumulated_content_` and the new SSE tool_use events being + appended, could we ever emit a `tool_use` block whose `input` + references text that's still present in `accumulated_content_`? Or + would the final accumulated content contain the same call span we + just emitted as a `tool_use`? +4. **`finish_reason` bump scope**: should `fr` flip to `tool_calls` + only when ≥1 tool actually survives `tool_allowed` (current + design), or whenever `parse_tool_calls` finds *any* match (even if + filtered)? The TOOL_BUFFER path's existing behavior is the + reference. + +## Codex review + +Run: 2026-05-31 against `lucebox.service` (image `fac7e0f-cuda12`, +Gemma4-26B-A4B, on bragi).

Calls failing the + allowlist are dropped before they reach `result.tool_calls`. The + plan's trigger condition is `if (!parsed.tool_calls.empty())`, so + `fr = "tool_calls"` is set only when ≥1 allow-listed call survived. + This matches Codex's recommendation; the perceived gap was the + reviewer not knowing about `parse_tool_calls`'s internal filter. + Documenting this explicitly in §3.5 for future readers. + +VERDICT was REVISE; revisions applied are §7 new test +(`strips_call_span_from_accumulated_text`) and §3.5 clarification on +the existing `tool_allowed` enforcement inside `parse_tool_calls`. +Proceed to implementation. + +## 6. Implementation outline (post-codex) + +1. Add `looks_like_plain_text_call` static helper in + `sse_emitter.cpp` (anonymous namespace next to `has_request_tools`). +2. Add the CONTENT-mode `else if` branch inside `emit_finish` between + the existing TOOL_BUFFER block (line 512-617) and the format-specific + final events switch (line 620). +3. Refactor the format-specific tool-call event emission inside the + TOOL_BUFFER branch into a private member `emit_tool_call_events(out)` + so both branches share the implementation.

Backends that manage the thinking budget server-side +(lucebox: count tokens, force `` before the cap, reserve reply room) +keep the answer intact. Backends that don't (some OpenRouter routes, mlx_lm) +reason to the `max_tokens` ceiling and truncate the answer, scoring far below +nothink. Measured: OpenRouter qwen3.6-27b think ds4-eval 48.9% vs 72.8% nothink, +32/92 rows length-capped. + +`max_tokens` is a total ceiling, so lowering it makes truncation worse. There is +no client-side way to bound thinking on a single stateless request. + +## Foundation: model-card resolution in luce-bench (build this first) + +Everything below is wrong unless the client uses the *right* tokens for the +*right* model. Today it doesn't: `_thinking.py` carries a hardcoded `FAMILY_TOKENS` +map (Qwen-only, `/think`/`/no_think` only); `runner.py` accepts a `model_card` but +luce-bench has no card registry, so a card only arrives from `/props.model_card` +on a lucebox server. Against OpenRouter/MLX it falls back to the Qwen guess and +knows nothing about terminators, reply reserves, effort tiers, or other families. + +Fix: give luce-bench a **card registry** resolvable by model id, mirroring the +cards in `share/model_cards/`. The server already proved the budget work is +card-driven; we duplicate the minimum of that on the client so it works without +`/props`. + +Resolution order per run: +1. `/props.model_card` — authoritative when present (lucebox). No preflight + needed; the server is telling us the exact card it loaded. +2. luce-bench bundled card registry, keyed by the server's + `normalize_model_card_stem` logic (so `qwen/qwen3.6-27b:free` → `qwen3.6-27b`). + Bundled as package data so the standalone PyPI build has them. +3. Family fallback (today's `FAMILY_TOKENS`) — last resort, tokens only, logged + as low-confidence. + +**A bundled-card id match is a HINT, not proof.** OpenRouter-style ids, aliases, +quant routes, and finetunes can normalize to `qwen3.6-27b` while serving behavior +that disagrees with the card. So for any source other than `/props.model_card`, +activation of think/nothink control or client abort is **gated on per +provider+route+model preflight success** (see Gating preflight) — not on the id +match alone. The match selects *which* card to test; the preflight decides whether +to *use* it. + +Normalization must be pinned by tests, not described: a shared test corpus +covering `qwen/qwen3.6-27b:free`, provider prefixes, version/quant suffixes, +aliases, and unknown revisions — luce-bench either shares the server's +implementation or is tested against the same corpus. + +Provenance, recorded per row: `card_source` (`props`|`bundled`|`family`|`none`), +`card_stem`, `card_hash`. When `/props` and a same-stem bundled card disagree, +warn and record both, so stale embedded cards and server/client skew are +auditable rather than silent. + +The card supplies, per model, exactly these and the feature reads them rather +than hardcoding: +- `thinking_control.{think_prompt_token, nothink_prompt_token, injection_point}` + — in-band mode control (Qwen: `/think`/`/no_think` at `user_turn_suffix`). +- `thinking_terminator_hint` — the force-close phrase (Qwen's sentence; Gemma's + differs). Any client-side termination uses THIS, never a hardcoded ``. +- `thinking_marker` — the channel delimiter for detecting end-of-thinking in the + stream. (Note: `qwen3.6-27b.json` currently has this null — a real gap; client + stream-termination needs it populated, or it falls back to `` tags if + present; genuinely unmarked output stays unsupported, never guessed.) +- `hard_limit_reply_budget` — reply reserve (4096). +- `reasoning_effort_tiers` — the budget values (low 4032 / medium 16128 / …). + +**Capability gate:** think-mode control and budgeting activate **only** for a +model that resolves to a thinking-capable card (has a thinking channel + the +fields above). For anything else, record `card="none"` / `not_thinking_capable` +and run plain — never inject tokens into a model that has no thinking channel. + +## Avoiding card duplication + +Canonical source is `share/model_cards/*.json` + `_schema.json`, read from disk by +the C++ server (`…/share/model_cards/.json`; `/opt/lucebox-hub/share/...` in +the image). That on-disk path is the server's contract and stays put. + +Duplication can only appear in **one** place: luce-bench published standalone to +PyPI, where it can't reach repo `share/`. In-repo and in-container, every consumer +(C++ server, `lucebox` CLI, luce-bench as a workspace member) already reads the +same `share/model_cards/` — no copy. + +Resolution: +- No hand-maintained second copy under `luce-bench/`. +- luce-bench **embeds the cards at build time** (hatch `force-include` / build + hook copies `share/model_cards/*.json` + `_schema.json` into the wheel/sdist as + `lucebench/_model_cards/`).

(Since the embedded files + aren't committed, hashing the source tree proves nothing — the guard must + inspect the built artifact.) Drift fails the build. +- Not a shared pip `lucebox-cards` package: the C++ server can't pip-install it, + so it would not unify consumers, only add a third artifact. + +## Two tiers, cheapest first + +### Tier 1 (preferred): native budget hints + +Before any client machinery, test whether a backend honors a budget hint it +already understands: + +- `reasoning_effort: low | medium` instead of `high`. +- Anthropic-shape `thinking: {type: enabled, budget_tokens: N}` (luce-bench + already sends this shape for the `probe` area). + +If a provider respects either, we get budgeted think with **zero client code** +(one request, one transcript — far cleaner than Tier 2). It is **not** free of +comparability concerns, though: `reasoning_effort: medium` is a different +benchmark setting from default/high think, so it is reported as its **own mode** +(`mode="native_effort"` / `"native_budget"`) and not pooled with plain think. +This is the default path the feature should pursue. luce-bench would expose +`--reasoning-effort {low,medium,high}` and/or `--thinking-budget-tokens N` that +set the request fields; the existing post-run verifier already records whether +the returned reasoning-token count actually fell. + +### Tier 2 (fallback, separate experimental mode): client abort + re-prompt + +Only for backends that (a) mark reasoning in the stream, (b) accept an +assistant-prefill continuation, and (c) ignore the Tier-1 native knobs. This set +may be small or empty; **gate building it on the preflight below.** + +Mechanism, framed honestly: +1. **Count** reasoning tokens as the stream arrives (see Counting). +2. **Stop** consuming and close the connection when over budget. Note: closing + the HTTP stream does **not** reliably stop server-side generation, billing, or + load. We stop *reading*; the server may keep going. +3. **Re-prompt** with a second, independent request that re-conditions on the + captured partial reasoning plus a terminator (card `thinking_terminator_hint`, + else `\n\n`) as an assistant-prefill turn, think disabled, with its + own reply `max_tokens` (default 4096). This is a **fresh conditioned sample, + not a resumption of the original decode.** The answer it produces is what we + grade. + +## Gating preflight (do this before building Tier 2) + +Probe each candidate backend and record a capability matrix: + +| capability | how to detect | +|---|---| +| native effort honored | send `reasoning_effort:medium` on N≥5 probe prompts; median reasoning tokens drop materially (e.g. ≥30%) vs `high` | +| native budget_tokens honored | send `thinking.budget_tokens=B`; reasoning tokens stay ≤ ~B on ≥80% of probes | +| reasoning marked in stream | `reasoning_content` deltas present, or `` tags in content | +| assistant-prefill accepted | continuation returns a clean answer, not an error/empty | +| usage after abort | does a closed stream still yield usage | + +If a backend passes Tier 1, Tier 2 is unnecessary for it. If no backend needs +Tier 2 (Tier 1 covers them, or they can't support the continuation), do not build +Tier 2; classify the unsupported backends instead. + +## Identifiability (Tier 2 hard constraint) + +Client termination only works when thinking is distinguishable in the stream: + +- **`reasoning_content` deltas** present → count those. Best case. +- **`…` in `content`** → detect open tag, count until close. +- **Unmarked** (reasoning indistinguishable from answer, no tags — the lucebox + /sindri server bug) → no boundary exists; do not guess.

This feature cannot and must + not try to fix unmarked output; that is a server-side issue. + +## Counting + +Final usage only arrives on the last chunk, so mid-stream the budget is checked +against an **approximate** reasoning-token estimate (char/4 over accumulated +reasoning text; no tokenizer dependency). Documented caveats: it miscounts +math/code/CJK/whitespace-heavy text, and it overshoots the budget by up to one +streamed chunk before the abort fires. The budget is a soft gate, not an exact +cutoff. + +## Comparability and result schema (the part that keeps numbers honest) + +Tier 2 is a **distinct benchmark mode**.

Codex CLI is an open source project led by OpenAI. You are expected to be precise, safe, and helpful. + +Your capabilities: + +- Receive user prompts and other context provided by the harness, such as files in the workspace. +- Communicate with the user by streaming thinking & responses, and by making & updating plans. +- Emit function calls to run terminal commands and apply patches. Depending on how this specific run is configured, you can request that these function calls be escalated to the user for approval before running.

You communicate efficiently, always keeping the user clearly informed about ongoing actions without unnecessary detail. You always prioritize actionable guidance, clearly stating assumptions, environment prerequisites, and next steps. Unless explicitly asked, you avoid excessively verbose explanations about your work. + +# AGENTS.md spec +- Repos often contain AGENTS.md files. These files can appear anywhere within the repository. +- These files are a way for humans to give you (the agent) instructions or tips for working within the container. +- Some examples might be: coding conventions, info about how code is organized, or instructions for how to run or test code. +- Instructions in AGENTS.md files: + - The scope of an AGENTS.md file is the entire directory tree rooted at the folder that contains it. + - For every file you touch in the final patch, you must obey instructions in any AGENTS.md file whose scope includes that file. + - Instructions about code style, structure, naming, etc. apply only to code within the AGENTS.md file's scope, unless the file states otherwise. + - More-deeply-nested AGENTS.md files take precedence in the case of conflicting instructions. + - Direct system/developer/user instructions (as part of a prompt) take precedence over AGENTS.md instructions. +- The contents of the AGENTS.md file at the root of the repo and any directories from the CWD up to the root are included with the developer message and don't need to be re-read. When working in a subdirectory of CWD, or a directory outside the CWD, check for any AGENTS.md files that may be applicable. + +## Responsiveness + +### Preamble messages + +Before making tool calls, send a brief preamble to the user explaining what you’re about to do. When sending preamble messages, follow these principles and examples: + +- **Logically group related actions**: if you’re about to run several related commands, describe them together in one preamble rather than sending a separate note for each. +- **Keep it concise**: be no more than 1-2 sentences, focused on immediate, tangible next steps. (8–12 words for quick updates). +- **Build on prior context**: if this is not your first tool call, use the preamble message to connect the dots with what’s been done so far and create a sense of momentum and clarity for the user to understand your next actions. +- **Keep your tone light, friendly and curious**: add small touches of personality in preambles feel collaborative and engaging. +- **Exception**: Avoid adding a preamble for every trivial read (e.g., `cat` a single file) unless it’s part of a larger grouped action. + +**Examples:** + +- “I’ve explored the repo; now checking the API route definitions.” +- “Next, I’ll patch the config and update the related tests.” +- “I’m about to scaffold the CLI commands and helper functions.” +- “Ok cool, so I’ve wrapped my head around the repo. Now digging into the API routes.” +- “Config’s looking tidy. Next up is patching helpers to keep things in sync.” +- “Finished poking at the DB gateway. I will now chase down error handling.” +- “Alright, build pipeline order is interesting. Checking how it reports failures.” +- “Spotted a clever caching util; now hunting where it gets used.” + +## Planning + +You have access to an `update_plan` tool which tracks steps and progress and renders them to the user. Using the tool helps demonstrate that you've understood the task and convey how you're approaching it. Plans can help to make complex, ambiguous, or multi-phase work clearer and more collaborative for the user. A good plan should break the task into meaningful, logically ordered steps that are easy to verify as you go. + +Note that plans are not for padding out simple work with filler steps or stating the obvious. The content of your plan should not involve doing anything that you aren't capable of doing (i.e. don't try to test things that you can't test). Do not use plans for simple or single-step queries that you can just do or answer immediately. + +Do not repeat the full contents of the plan after an `update_plan` call — the harness already displays it. Instead, summarize the change made and highlight any important context or next step. + +Before running a command, consider whether or not you have completed the previous step, and make sure to mark it as completed before moving on to the next step. It may be the case that you complete all steps in your plan after a single pass of implementation. If this is the case, you can simply mark all the planned steps as completed. Sometimes, you may need to change plans in the middle of a task: call `update_plan` with the updated plan and make sure to provide an `explanation` of the rationale when doing so. + +Use a plan when: + +- The task is non-trivial and will require multiple actions over a long time horizon. +- There are logical phases or dependencies where sequencing matters. +- The work has ambiguity that benefits from outlining high-level goals. +- You want intermediate checkpoints for feedback and validation. +- When the user asked you to do more than one thing in a single prompt +- The user has asked you to use the plan tool (aka "TODOs") +- You generate additional steps while working, and plan to do them before yielding to the user + +### Examples + +**High-quality plans** + +Example 1: + +1.

Please keep going until the query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved. Autonomously resolve the query to the best of your ability, using the tools available to you, before coming back to the user. Do NOT guess or make up an answer. + +You MUST adhere to the following criteria when solving queries: + +- Working on the repo(s) in the current environment is allowed, even if they are proprietary. +- Analyzing code for vulnerabilities is allowed. +- Showing user code and tool call details is allowed. +- Use the `apply_patch` tool to edit files (NEVER try `applypatch` or `apply-patch`, only `apply_patch`): {"command":["apply_patch","*** Begin Patch\\n*** Update File: path/to/file.py\\n@@ def example():\\n- pass\\n+ return 123\\n*** End Patch"]} + +If completing the user's task requires writing or modifying files, your code and final answer should follow these coding guidelines, though user instructions (i.e. AGENTS.md) may override these guidelines: + +- Fix the problem at the root cause rather than applying surface-level patches, when possible. +- Avoid unneeded complexity in your solution. +- Do not attempt to fix unrelated bugs or broken tests. It is not your responsibility to fix them. (You may mention them to the user in your final message though.) +- Update documentation as necessary. +- Keep changes consistent with the style of the existing codebase. Changes should be minimal and focused on the task. +- Use `git log` and `git blame` to search the history of the codebase if additional context is required. +- NEVER add copyright or license headers unless specifically requested. +- Do not waste tokens by re-reading files after calling `apply_patch` on them. The tool call will fail if it didn't work. The same goes for making folders, deleting folders, etc. +- Do not `git commit` your changes or create new git branches unless explicitly requested. +- Do not add inline comments within code unless explicitly requested. +- Do not use one-letter variable names unless explicitly requested. +- NEVER output inline citations like "【F:README.md†L5-L14】" in your outputs. The CLI is not able to render these so they will just be broken in the UI. Instead, if you output valid filepaths, users will be able to click on them to open the files in their editor. + +## Validating your work + +If the codebase has tests or the ability to build or run, consider using them to verify that your work is complete. + +When testing, your philosophy should be to start as specific as possible to the code you changed so that you can catch issues efficiently, then make your way to broader tests as you build confidence. If there's no test for the code you changed, and if the adjacent patterns in the codebases show that there's a logical place for you to add a test, you may do so. However, do not add tests to codebases with no tests. + +Similarly, once you're confident in correctness, you can suggest or use formatting commands to ensure that your code is well formatted. If there are issues you can iterate up to 3 times to get formatting right, but if you still can't manage it's better to save the user time and present them a correct solution where you call out the formatting in your final message. If the codebase does not have a formatter configured, do not add one. + +For all of testing, running, building, and formatting, do not attempt to fix unrelated bugs. It is not your responsibility to fix them. (You may mention them to the user in your final message though.) + +Be mindful of whether to run validation commands proactively. In the absence of behavioral guidance: + +- When running in non-interactive approval modes like **never** or **on-failure**, proactively run tests, lint and do whatever you need to ensure you've completed the task. +- When working in interactive approval modes like **untrusted**, or **on-request**, hold off on running tests or lint commands until the user is ready for you to finalize your output, because these commands take time to run and slow down iteration. Instead suggest what you want to do next, and let the user confirm first. +- When working on test-related tasks, such as adding tests, fixing tests, or reproducing a bug to verify behavior, you may proactively run tests regardless of approval mode. Use your judgement to decide whether this is a test-related task. + +## Ambition vs. precision + +For tasks that have no prior context (i.e. the user is starting something brand new), you should feel free to be ambitious and demonstrate creativity with your implementation. + +If you're operating in an existing codebase, you should make sure you do exactly what the user asks with surgical precision. Treat the surrounding codebase with respect, and don't overstep (i.e. changing filenames or variables unnecessarily). You should balance being sufficiently ambitious and proactive when completing tasks of this nature. + +You should use judicious initiative to decide on the right level of detail and complexity to deliver based on the user's needs. This means showing good judgment that you're capable of doing the right extras without gold-plating. This might be demonstrated by high-value, creative touches when scope of the task is vague; while being surgical and targeted when scope is tightly specified. + +## Sharing progress updates + +For especially longer tasks that you work on (i.e. requiring many tool calls, or a plan with multiple steps), you should provide progress updates back to the user at reasonable intervals. These updates should be structured as a concise sentence or two (no more than 8-10 words long) recapping progress so far in plain language: this update demonstrates your understanding of what needs to be done, progress so far (i.e. files explores, subtasks complete), and where you're going next. + +Before doing large chunks of work that may incur latency as experienced by the user (i.e. writing a new file), you should send a concise message to the user with an update indicating what you're about to do to ensure they know what you're spending time on. Don't start editing or writing large files before informing the user what you are doing and why. + +The messages you send before tool calls should describe what is immediately about to be done next in very concise language. If there was previous work done, this preamble message should also include a note about the work done so far to bring the user along. + +## Presenting your work and final message + +Your final message should read naturally, like an update from a concise teammate. For casual conversation, brainstorming tasks, or quick questions from the user, respond in a friendly, conversational tone. You should ask questions, suggest ideas, and adapt to the user’s style. If you've finished a large amount of work, when describing what you've done to the user, you should follow the final answer formatting guidelines to communicate substantive changes. You don't need to add structured formatting for one-word answers, greetings, or purely conversational exchanges. + +You can skip heavy formatting for single, simple actions or confirmations. In these cases, respond in plain sentences with any relevant next step or quick option.

In these cases, it's bad to output your proposed solution in a message, you should go ahead and actually implement the change. If you encounter challenges or blockers, you should attempt to resolve them yourself. + +## Responsiveness + +## Planning + +You have access to an `update_plan` tool which tracks steps and progress and renders them to the user. Using the tool helps demonstrate that you've understood the task and convey how you're approaching it. Plans can help to make complex, ambiguous, or multi-phase work clearer and more collaborative for the user. A good plan should break the task into meaningful, logically ordered steps that are easy to verify as you go. + +Note that plans are not for padding out simple work with filler steps or stating the obvious. The content of your plan should not involve doing anything that you aren't capable of doing (i.e. don't try to test things that you can't test). Do not use plans for simple or single-step queries that you can just do or answer immediately. + +Do not repeat the full contents of the plan after an `update_plan` call — the harness already displays it. Instead, summarize the change made and highlight any important context or next step. + +Before running a command, consider whether or not you have completed the previous step, and make sure to mark it as completed before moving on to the next step. It may be the case that you complete all steps in your plan after a single pass of implementation. If this is the case, you can simply mark all the planned steps as completed. Sometimes, you may need to change plans in the middle of a task: call `update_plan` with the updated plan and make sure to provide an `explanation` of the rationale when doing so. + +Maintain statuses in the tool: exactly one item in_progress at a time; mark items complete when done; post timely status transitions. Do not jump an item from pending to completed: always set it to in_progress first. Do not batch-complete multiple items after the fact.

Persist until the task is fully handled end-to-end within the current turn whenever feasible and persevere even when function calls fail. Only terminate your turn when you are sure that the problem is solved. Autonomously resolve the query to the best of your ability, using the tools available to you, before coming back to the user. Do NOT guess or make up an answer. + +You MUST adhere to the following criteria when solving queries: + +- Working on the repo(s) in the current environment is allowed, even if they are proprietary. +- Analyzing code for vulnerabilities is allowed. +- Showing user code and tool call details is allowed. +- Use the `apply_patch` tool to edit files (NEVER try `applypatch` or `apply-patch`, only `apply_patch`). This is a FREEFORM tool, so do not wrap the patch in JSON. + +If completing the user's task requires writing or modifying files, your code and final answer should follow these coding guidelines, though user instructions (i.e. AGENTS.md) may override these guidelines: + +- Fix the problem at the root cause rather than applying surface-level patches, when possible. +- Avoid unneeded complexity in your solution. +- Do not attempt to fix unrelated bugs or broken tests. It is not your responsibility to fix them. (You may mention them to the user in your final message though.) +- Update documentation as necessary. +- Keep changes consistent with the style of the existing codebase. Changes should be minimal and focused on the task. +- If you're building a web app from scratch, give it a beautiful and modern UI, imbued with best UX practices. +- Use `git log` and `git blame` to search the history of the codebase if additional context is required. +- NEVER add copyright or license headers unless specifically requested. +- Do not waste tokens by re-reading files after calling `apply_patch` on them. The tool call will fail if it didn't work. The same goes for making folders, deleting folders, etc. +- Do not `git commit` your changes or create new git branches unless explicitly requested. +- Do not add inline comments within code unless explicitly requested. +- Do not use one-letter variable names unless explicitly requested. +- NEVER output inline citations like "【F:README.md†L5-L14】" in your outputs. The CLI is not able to render these so they will just be broken in the UI. Instead, if you output valid filepaths, users will be able to click on them to open the files in their editor. + +## Validating your work + +If the codebase has tests, or the ability to build or run tests, consider using them to verify changes once your work is complete. + +When testing, your philosophy should be to start as specific as possible to the code you changed so that you can catch issues efficiently, then make your way to broader tests as you build confidence. If there's no test for the code you changed, and if the adjacent patterns in the codebases show that there's a logical place for you to add a test, you may do so. However, do not add tests to codebases with no tests. + +Similarly, once you're confident in correctness, you can suggest or use formatting commands to ensure that your code is well formatted. If there are issues you can iterate up to 3 times to get formatting right, but if you still can't manage it's better to save the user time and present them a correct solution where you call out the formatting in your final message. If the codebase does not have a formatter configured, do not add one. + +For all of testing, running, building, and formatting, do not attempt to fix unrelated bugs. It is not your responsibility to fix them. (You may mention them to the user in your final message though.) + +Be mindful of whether to run validation commands proactively. In the absence of behavioral guidance: + +- When running in non-interactive approval modes like **never** or **on-failure**, you can proactively run tests, lint and do whatever you need to ensure you've completed the task. If you are unable to run tests, you must still do your utmost best to complete the task. +- When working in interactive approval modes like **untrusted**, or **on-request**, hold off on running tests or lint commands until the user is ready for you to finalize your output, because these commands take time to run and slow down iteration. Instead suggest what you want to do next, and let the user confirm first. +- When working on test-related tasks, such as adding tests, fixing tests, or reproducing a bug to verify behavior, you may proactively run tests regardless of approval mode. Use your judgement to decide whether this is a test-related task. + +## Ambition vs. precision + +For tasks that have no prior context (i.e. the user is starting something brand new), you should feel free to be ambitious and demonstrate creativity with your implementation. + +If you're operating in an existing codebase, you should make sure you do exactly what the user asks with surgical precision. Treat the surrounding codebase with respect, and don't overstep (i.e. changing filenames or variables unnecessarily). You should balance being sufficiently ambitious and proactive when completing tasks of this nature. + +You should use judicious initiative to decide on the right level of detail and complexity to deliver based on the user's needs. This means showing good judgment that you're capable of doing the right extras without gold-plating. This might be demonstrated by high-value, creative touches when scope of the task is vague; while being surgical and targeted when scope is tightly specified. + +## Presenting your work + +Your final message should read naturally, like an update from a concise teammate. For casual conversation, brainstorming tasks, or quick questions from the user, respond in a friendly, conversational tone. You should ask questions, suggest ideas, and adapt to the user’s style. If you've finished a large amount of work, when describing what you've done to the user, you should follow the final answer formatting guidelines to communicate substantive changes. You don't need to add structured formatting for one-word answers, greetings, or purely conversational exchanges. + +You can skip heavy formatting for single, simple actions or confirmations. In these cases, respond in plain sentences with any relevant next step or quick option. Reserve multi-section structured responses for results that need grouping or explanation. + +The user is working on the same computer as you, and has access to your work.

The bead's <description> and <acceptance> are the contract: every AC must be provably satisfied by a specific code, test, or file after your commit. ## Step 0: size check Too big if any holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs. - Description names multiple feature-sized pieces. - More than ~500 lines across ~5+ files in unrelated packages. - If the bead description exceeds 8000 bytes, use a split-first pass. - Auto-decomposition is capped at depth 2: root beads may split once, children once more; reject third-level splits with an explanation. If too big, decompose: 1. `ddx bead create` for each child (copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. 4. Write `no_changes_rationale.txt` under the bead metadata `bundle` path with child IDs, then stop. Decomposition alone is success. Do not mix it with implementation. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC to concrete evidence (test, file, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Run git/index mutations sequentially; do not use parallel tool calls for `git add`, `git commit`, or other staging/commit commands. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - If `lefthook run pre-commit` depends on staged files, rerun it after staging the exact commit set. A `no-staged-files` run is not acceptance evidence. - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - Current-bead lifecycle is orchestrator-owned. Do not run `ddx bead update <bead-id> --claim`, `ddx bead update <bead-id> --status <status>`, `ddx bead update <bead-id> --unclaim`, or `ddx bead close <bead-id>`. Step 0 still allows `ddx bead create`, `ddx bead dep add`, and `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. - If you cannot finish, write `no_changes_rationale.txt` under the bead metadata `bundle` path before exiting. No commit or rationale \u21d2 DDx records `no_evidence_produced`. ## no_changes contract The `no_changes_rationale.txt` file under the bead metadata `bundle` path must contain one of: - `verification_command: <cmd>` \u2014 repo cwd; exit 0 closes, nonzero rejects. - `status: open` + `reason: <retryable>` \u2014 open, smart retry. - `status: proposed` + `reason: <operator needed>` \u2014 operator lane. - `status: blocked` + `reason: <external blocker>` \u2014 blocked lane. No pseudo-statuses. Bare rationales and `status: needs_investigation` are rejected. For orchestrator decomposition, add `orchestrator_action: decompose` alongside `status: open`. ## Reports Reports go under the bead metadata `bundle` path in `.ddx/executions/`. **Never write reports to `/tmp` or outside the repo**. Use a named in-repo path when given; otherwise write `<short-name>.md` there. Commit it with the code. ## Mode and overrides DDX_MODE=bead_execution: edit code/docs for bead AC. Only broad queue-steward default is overridden; tracker, merge-policy, verification, safety stay active. Bead description/AC override CLAUDE.md, AGENTS.md, and defaults. ## Review gate - The review is a gate, not an escape hatch \u2014 meet every AC in this pass. - Address every BLOCKING `<review-findings>` item; do not declare `no_changes` with blocking findings open. ## Constraints - Work only inside this execution worktree. - Keep `.ddx/executions/` intact \u2014 DDx uses it as execution evidence. - **Never run `ddx init`** \u2014 the workspace is initialized. - Do not modify files outside the bead's named scope. - Do not rewrite CLAUDE.md, AGENTS.md, or other instruction files unless the bead asks. ## When the work is done After the commit succeeds and every AC is verified, stop. Return control to the orchestrator.\n \n \n Refactor materialization queue for pipelined build and merge stages\n \nSplit the queue worker and executor contract so build_source_attempt can run ahead of merge execution. In scope: crates/niflheim-delta-writer/src/queue/worker.rs, crates/niflheim-delta-writer/src/queue/types.rs, crates/niflheim-delta-writer/src/materializer/executor.rs, and the queue and materializer unit tests that need to model the two-stage flow. Out of scope: integration tests and Sindri perf evidence. The child must preserve retry and DLQ semantics per request and keep staging-quota backpressure intact while allowing the next request's build stage to begin before the current request's merge phase completes.\n \n \n1. MaterializationExecutor exposes a split build and merge contract with backward-compatible materialize behavior. 2. MaterializationQueue::start_worker launches builds independently from merges so a later request can start building before an earlier request finishes merging. 3. A unit test in the queue or materializer crate proves the split pipeline overlaps build and merge phases. 4. Workspace tests for the touched crate pass.\n \n spec:SD-009, spec:SD-023, materialization, perf, sindri, prism, concurrency, ac-quality:needs-refinement\n \n \n \n No governing references were pre-resolved. The bead description above is the primary contract. If it names files, specs, or prior beads, read them first. Ground decisions in repository state; do not guess.\n \n\n", + "initial_state": { + "cwd": "/.cache/ddx/exec-wt/.execute-bead-wt-niflheim-07f6f8ff-20260528T010451-d88e26f9", + "git_ref": null, +

"id": "claude-2026-05-28-execute-bead-instructions-you-ar-c41604143b", + "source": "claude-code", + "prompt": "\n \nYou are executing one bead in an isolated DDx execution worktree. The bead's <description> and <acceptance> are the contract: every AC must be provably satisfied by a specific code, test, or file after your commit. ## Step 0: size check Too big if any holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs. - Description names multiple feature-sized pieces. - More than ~500 lines across ~5+ files in unrelated packages. - If the bead description exceeds 8000 bytes, use a split-first pass. - Auto-decomposition is capped at depth 2: root beads may split once, children once more; reject third-level splits with an explanation. If too big, decompose: 1. `ddx bead create` for each child (copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. 4. Write `no_changes_rationale.txt` under the bead metadata `bundle` path with child IDs, then stop. Decomposition alone is success. Do not mix it with implementation. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC to concrete evidence (test, file, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Run git/index mutations sequentially; do not use parallel tool calls for `git add`, `git commit`, or other staging/commit commands. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - If `lefthook run pre-commit` depends on staged files, rerun it after staging the exact commit set. A `no-staged-files` run is not acceptance evidence. - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - Current-bead lifecycle is orchestrator-owned. Do not run `ddx bead update <bead-id> --claim`, `ddx bead update <bead-id> --status <status>`, `ddx bead update <bead-id> --unclaim`, or `ddx bead close <bead-id>`. Step 0 still allows `ddx bead create`, `ddx bead dep add`, and `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. - If you cannot finish, write `no_changes_rationale.txt` under the bead metadata `bundle` path before exiting. No commit or rationale \u21d2 DDx records `no_evidence_produced`. ## no_changes contract The `no_changes_rationale.txt` file under the bead metadata `bundle` path must contain one of: - `verification_command: <cmd>` \u2014 repo cwd; exit 0 closes, nonzero rejects. - `status: open` + `reason: <retryable>` \u2014 open, smart retry. - `status: proposed` + `reason: <operator needed>` \u2014 operator lane. - `status: blocked` + `reason: <external blocker>` \u2014 blocked lane. No pseudo-statuses. Bare rationales and `status: needs_investigation` are rejected. For orchestrator decomposition, add `orchestrator_action: decompose` alongside `status: open`. ## Reports Reports go under the bead metadata `bundle` path in `.ddx/executions/`. **Never write reports to `/tmp` or outside the repo**. Use a named in-repo path when given; otherwise write `<short-name>.md` there. Commit it with the code. ## Mode and overrides DDX_MODE=bead_execution: edit code/docs for bead AC. Only broad queue-steward default is overridden; tracker, merge-policy, verification, safety stay active. Bead description/AC override CLAUDE.md, AGENTS.md, and defaults. ## Review gate - The review is a gate, not an escape hatch \u2014 meet every AC in this pass. - Address every BLOCKING `<review-findings>` item; do not declare `no_changes` with blocking findings open. ## Constraints - Work only inside this execution worktree. - Keep `.ddx/executions/` intact \u2014 DDx uses it as execution evidence. - **Never run `ddx init`** \u2014 the workspace is initialized. - Do not modify files outside the bead's named scope. - Do not rewrite CLAUDE.md, AGENTS.md, or other instruction files unless the bead asks. ## When the work is done After the commit succeeds and every AC is verified, stop. Return control to the orchestrator. ## Decomposition depth cap This bead is already at decomposition depth 2. Do not create another child layer; if it is still too large, reject the split with a short explanation and write no_changes_rationale.txt instead. \n \n \n ARCH-A.5b: collect shard_count 4 and 8 validation evidence\n \nPROBLEM ARCH-A.5 requires the higher-shard validation data needed to test linear scaling and the CPU utilization exit gate. This child owns shard_count=4 and shard_count=8 evidence collection. ROOT CAUSE <governing>docs/helix/02-design/system-design/SD-011-pipeline-performance-model.md:9 (SD-011 \u00a79 spike exit gate); parent: niflheim-3bd0fce8 (ARCH-A spike); decomposed parent: niflheim-520db87a.</governing> DEPENDENCIES - ARCH-A.1 (per-shard materializer queue) - ARCH-A.2 (per-shard WAL writers) - ARCH-A.3 (per-shard Kafka consumer) - ARCH-A.4 (wipe guard \u2014 so the runs at different shard_counts are honest, not silently corrupt) PROPOSED FIX Run prism_stress_local for the 32-partition workload (32k\u00d7300B realistic, 100\u00d710) at shard_count=4 and shard_count=8. Capture throughput, CPU%, run metadata, logs, and flame graph artifacts under the same docs/helix/04-build/evidence/IP-010/throughput/<timestamp>-arch-a/ evidence directory used for ARCH-A.5. Record shard_count=4 sustained ingest CPU alongside the 11% baseline so the aggregate write-up can evaluate the >25% pass criterion. NON-SCOPE - Do not run shard_count=1 or shard_count=2; those belong to a sibling child bead. - Do not decide success vs lesson. - Do not file follow-up beads. - Do not update SD-011 \u00a79 with the binding constraint or next architectural move. - Do not implement the next architectural step if needed; file as a separate bead. - Do not implement parent acceptance criteria assigned to sibling child beads. - Preserve Cross-refs: ADR-061, SD-011 \u00a79.\n \n \n1. Evidence for shard_count=4 and shard_count=8 exists under docs/helix/04-build/evidence/IP-010/throughput/ARCH-A/<run-id>/, including rate/cpu data, run metadata, logs, and flame graph artifacts or an explicit per-run note if flame capture is unavailable. 2. Evidence records shard_count=4 sustained ingest CPU% alongside the 11% baseline and includes enough context to evaluate the >25% criterion. 3. Evidence records the workload shape: prism_stress_local, 32 Kafka partitions, 32k rows/s target, 300B realistic rows, 100x10 cardinality. 4. scripts/with-pinned-rust.sh cargo test -p arch-a-validation --release --test arch_a_validation passes. 5. cd benchmarks/throughput && uv run pytest tests/test_arch_a_sweep.py passes. 6. lefthook run pre-commit passes.\n \n \nAccepted/unblocked 2026-05-18: operator requested queue unblocking. Removed the non-existent cd cli && go test ./... gate and replaced it with repo-real arch-a-validation and throughput harness checks. Redpanda compose startup was verified after commit 90cd8348.\n \n spec:SD-011, perf, throughput, architecture, sharding, area:perf, kind:validation, decomposed, ac-quality:needs-refinement\n \n \n \n No governing references were pre-resolved. The bead description above is the primary contract. If it names files, specs, or prior beads, read them first. Ground decisions in repository state; do not guess.\n \n\n", + "initial_state": { + "cwd": "/.cache/ddx/exec-wt/.execute-bead-wt-niflheim-09103a98-20260528T040639-c31b855d", + "git_ref": null, +

The bead's <description> and <acceptance> are the contract: every AC must be provably satisfied by a specific code, test, or file after your commit. ## Step 0: size check Too big if any holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs. - Description names multiple feature-sized pieces. - More than ~500 lines across ~5+ files in unrelated packages. - If the bead description exceeds 8000 bytes, use a split-first pass. - Auto-decomposition is capped at depth 2: root beads may split once, children once more; reject third-level splits with an explanation. If too big, decompose: 1. `ddx bead create` for each child (copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. 4. Write `no_changes_rationale.txt` under the bead metadata `bundle` path with child IDs, then stop. Decomposition alone is success. Do not mix it with implementation. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC to concrete evidence (test, file, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Run git/index mutations sequentially; do not use parallel tool calls for `git add`, `git commit`, or other staging/commit commands. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - If `lefthook run pre-commit` depends on staged files, rerun it after staging the exact commit set. A `no-staged-files` run is not acceptance evidence. - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - Current-bead lifecycle is orchestrator-owned. Do not run `ddx bead update <bead-id> --claim`, `ddx bead update <bead-id> --status <status>`, `ddx bead update <bead-id> --unclaim`, or `ddx bead close <bead-id>`. Step 0 still allows `ddx bead create`, `ddx bead dep add`, and `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. - If you cannot finish, write `no_changes_rationale.txt` under the bead metadata `bundle` path before exiting. No commit or rationale \u21d2 DDx records `no_evidence_produced`. ## no_changes contract The `no_changes_rationale.txt` file under the bead metadata `bundle` path must contain one of: - `verification_command: <cmd>` \u2014 repo cwd; exit 0 closes, nonzero rejects. - `status: open` + `reason: <retryable>` \u2014 open, smart retry. - `status: proposed` + `reason: <operator needed>` \u2014 operator lane. - `status: blocked` + `reason: <external blocker>` \u2014 blocked lane. No pseudo-statuses. Bare rationales and `status: needs_investigation` are rejected. For orchestrator decomposition, add `orchestrator_action: decompose` alongside `status: open`. ## Reports Reports go under the bead metadata `bundle` path in `.ddx/executions/`. **Never write reports to `/tmp` or outside the repo**. Use a named in-repo path when given; otherwise write `<short-name>.md` there. Commit it with the code. ## Mode and overrides DDX_MODE=bead_execution: edit code/docs for bead AC. Only broad queue-steward default is overridden; tracker, merge-policy, verification, safety stay active. Bead description/AC override CLAUDE.md, AGENTS.md, and defaults. ## Review gate - The review is a gate, not an escape hatch \u2014 meet every AC in this pass. - Address every BLOCKING `<review-findings>` item; do not declare `no_changes` with blocking findings open. ## Constraints - Work only inside this execution worktree. - Keep `.ddx/executions/` intact \u2014 DDx uses it as execution evidence. - **Never run `ddx init`** \u2014 the workspace is initialized. - Do not modify files outside the bead's named scope. - Do not rewrite CLAUDE.md, AGENTS.md, or other instruction files unless the bead asks. ## When the work is done After the commit succeeds and every AC is verified, stop. Return control to the orchestrator.\n \n \n ARCH-A/5: linear-scaling validation against prism_stress_local\n \n<governing>ADR-061 \u00a7"Validation gate", SD-011 \u00a74.2a (0.7\u00d7 linear scaling target), parent niflheim-3bd0fce8. Depends on niflheim-41af19a2 (ARCH-A/3) and niflheim-7817b555 (ARCH-A/4).</governing> ## Scope End-to-end validation that ARCH-A delivers the SD-011 \u00a74.2a perf target: `rate(shard_count=N) \u2265 0.7 \u00d7 N \u00d7 rate(shard_count=1)` for N \u2208 {2, 4, 8} on the prism_stress_local workload (32 Kafka partitions). Capture evidence under `docs/helix/04-build/evidence/IP-010/throughput/`. ## Implementation ### Workload Use `benchmarks/throughput/src/fast_producer.py` against the local Redpanda + niflheim setup, with the pre-generated 500k-record JSONL fixture (or generate a larger one for longer runs). Topic: `prism_stress_local` with 32 Kafka partitions. ### Test matrix For each `shard_count \u2208 {1, 2, 4, 8}`: 1. Update niflheim config: `[ingest] shard_count = N`. 2. Wipe the data dir (ADR-061: shard_count change requires wipe). 3. Start niflheim. Wait for ready. 4. Drive 5 minutes of sustained load via `fast_producer.py --parallelism 16 --duration 300 --repeat`. 5. Sample niflheim CPU, RSS, /dev/sdd %util, eth0 RX, niflheim proc_write_bytes every 5s (reuse `/tmp/sweep_harness.py` from the prior fast-producer evidence). 6. Capture niflheim observed consume rate via `system.source_progress` (commit_frontier_offset delta). ### Per-step capture - `step_<shard_count>.json` \u2014 producer rate, niflheim observed rate, CPU max/avg, disk %util max, RSS max, proc_write_mbps, net_rx_mbps - `samples_<shard_count>.csv` \u2014 5s-interval samples - `fastprod_<shard_count>.json` \u2014 raw fast-producer output ### Analysis Compute the linear-scaling ratio per N: ``` ratio(N) = niflheim_observed_rate(N) / (N \u00d7 niflheim_observed_rate(1)) ``` Target: `ratio(N) >= 0.7` for N \u2208 {2, 4, 8}. ### Evidence Save under `docs/helix/04-build/evidence/IP-010/throughput/<TS>-arch-a-validation-<sha>/`: - `SUMMARY.md` \u2014 comparison table; whether the 0.7\u00d7 target is met per N; classification of dominant bottleneck if the target is missed (disk saturation, CPU saturation per shard, merge_gate, etc.); recommendation on default `shard_count` post-validation. - Per-step JSONs + sample CSVs. ### Spike exit gate (per ADR-061) If validation succeeds: file follow-up beads for (a) per-shard Prometheus metrics, (b) re-shard utility tool, (c) cross-shard tenant fairness if skew was observed. If validation fails: SUMMARY.md must classify why (e.g., "shard_count=8 still saturates at 12 cores because per-shard WAL writer is now the bound; recommend further sharding by sub-partition or examining bottlenecks downstream of WAL append"). Decide whether to revert ARCH-A or merge it as a stepping stone. ## Acceptance 1. Sweep run for shard_count \u2208 {1, 2, 4, 8} completes; evidence directory exists with all per-step artifacts. 2. SUMMARY.md present with the ratio table. 3. **Either:** the 0.7\u00d7 target is met for at least N \u2208 {2, 4}; the spike is judged a success. 4. **Or:** the SUMMARY classifies the next bottleneck and proposes the follow-up direction (per ADR-061 spike exit gate). 5. If success: niflheim.toml default `shard_count` is updated to the post-validation value (likely `num_cores / 2`). 6. The cloud catchup may run alongside or be paused \u2014 operator's call; document the choice in SUMMARY.md. ## Out of scope - Re-shard tool (utility to migrate WAL data between shard layouts). - Per-shard observability beyond what's needed to interpret the sweep. - Power-loss recovery validation (covered separately via ADR-060 path, not this bead). ## References - ADR-061 \u00a7"Validation gate", \u00a7"Spike exit gate" - SD-011 \u00a74.2a \u2014 roofline equation and 0.7\u00d7 target - fast_producer harness: `benchmarks/throughput/src/fast_producer.py` - Reference sweep harness: prior evidence at `docs/helix/04-build/evidence/IP-010/throughput/20260510T175216Z-fastprod-sweep-2a3cf0af/sweep_harness.py`\n \n \n \nUnblocked 2026-05-18: the prior Redpanda/AIO blocker was stale after commit 90cd8348 bounded Redpanda test storage with an owned tmpfs mount.

The bead's <description> and <acceptance> are the contract: every AC must be provably satisfied by a specific code, test, or file after your commit. ## Step 0: size check Too big if any holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs. - Description names multiple feature-sized pieces. - More than ~500 lines across ~5+ files in unrelated packages. - If the bead description exceeds 8000 bytes, use a split-first pass. - Auto-decomposition is capped at depth 2: root beads may split once, children once more; reject third-level splits with an explanation. If too big, decompose: 1. `ddx bead create` for each child (copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. 4. Write `no_changes_rationale.txt` under the bead metadata `bundle` path with child IDs, then stop. Decomposition alone is success. Do not mix it with implementation. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC to concrete evidence (test, file, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Run git/index mutations sequentially; do not use parallel tool calls for `git add`, `git commit`, or other staging/commit commands. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - If `lefthook run pre-commit` depends on staged files, rerun it after staging the exact commit set. A `no-staged-files` run is not acceptance evidence. - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - Current-bead lifecycle is orchestrator-owned. Do not run `ddx bead update <bead-id> --claim`, `ddx bead update <bead-id> --status <status>`, `ddx bead update <bead-id> --unclaim`, or `ddx bead close <bead-id>`. Step 0 still allows `ddx bead create`, `ddx bead dep add`, and `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. - If you cannot finish, write `no_changes_rationale.txt` under the bead metadata `bundle` path before exiting. No commit or rationale \u21d2 DDx records `no_evidence_produced`. ## no_changes contract The `no_changes_rationale.txt` file under the bead metadata `bundle` path must contain one of: - `verification_command: <cmd>` \u2014 repo cwd; exit 0 closes, nonzero rejects. - `status: open` + `reason: <retryable>` \u2014 open, smart retry. - `status: proposed` + `reason: <operator needed>` \u2014 operator lane. - `status: blocked` + `reason: <external blocker>` \u2014 blocked lane. No pseudo-statuses. Bare rationales and `status: needs_investigation` are rejected. For orchestrator decomposition, add `orchestrator_action: decompose` alongside `status: open`. ## Reports Reports go under the bead metadata `bundle` path in `.ddx/executions/`. **Never write reports to `/tmp` or outside the repo**. Use a named in-repo path when given; otherwise write `<short-name>.md` there. Commit it with the code. ## Mode and overrides DDX_MODE=bead_execution: edit code/docs for bead AC. Only broad queue-steward default is overridden; tracker, merge-policy, verification, safety stay active. Bead description/AC override CLAUDE.md, AGENTS.md, and defaults. ## Review gate - The review is a gate, not an escape hatch \u2014 meet every AC in this pass. - Address every BLOCKING `<review-findings>` item; do not declare `no_changes` with blocking findings open. ## Constraints - Work only inside this execution worktree. - Keep `.ddx/executions/` intact \u2014 DDx uses it as execution evidence. - **Never run `ddx init`** \u2014 the workspace is initialized. - Do not modify files outside the bead's named scope. - Do not rewrite CLAUDE.md, AGENTS.md, or other instruction files unless the bead asks. ## When the work is done After the commit succeeds and every AC is verified, stop. Return control to the orchestrator.\n \n \n Add integration failure-isolation coverage for pipelined materialization\n \nAdd an integration test under tests/integration/materialization that uses a synthetic pipelined executor to prove a build failure in request K+1 does not roll back a successful merge for request K. The test should observe the first request completing successfully, the second request failing during build, and the store or queue state remaining committed for the first request. Out of scope: the queue refactor itself and Sindri benchmarking.\n \n \n1. An integration test under tests/integration/materialization covers the K and K+1 failure isolation case. 2. The test proves request K succeeds even when request K+1 fails during build. 3. The test runs with the crate's standard integration-test command and passes.\n \n spec:SD-009, spec:SD-023, materialization, perf, sindri, prism, concurrency, ac-quality:needs-refinement\n \n \n \n No governing references were pre-resolved. The bead description above is the primary contract. If it names files, specs, or prior beads, read them first. Ground decisions in repository state; do not guess.\n \n\n", + "initial_state": { + "cwd": "/.cache/ddx/exec-wt/.execute-bead-wt-niflheim-780a1278-20260528T014337-bbbbfcb0", + "git_ref": null, +

"source": "claude-code", + "prompt": "\n \nYou are executing one bead in an isolated DDx execution worktree. The bead's <description> and <acceptance> are the contract: every AC must be provably satisfied by a specific code, test, or file after your commit. ## Step 0: size check Too big if any holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs. - Description names multiple feature-sized pieces. - More than ~500 lines across ~5+ files in unrelated packages. - If the bead description exceeds 8000 bytes, use a split-first pass. - Auto-decomposition is capped at depth 2: root beads may split once, children once more; reject third-level splits with an explanation. If too big, decompose: 1. `ddx bead create` for each child (copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. 4. Write `no_changes_rationale.txt` under the bead metadata `bundle` path with child IDs, then stop. Decomposition alone is success. Do not mix it with implementation. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC to concrete evidence (test, file, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Run git/index mutations sequentially; do not use parallel tool calls for `git add`, `git commit`, or other staging/commit commands. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - If `lefthook run pre-commit` depends on staged files, rerun it after staging the exact commit set. A `no-staged-files` run is not acceptance evidence. - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - Current-bead lifecycle is orchestrator-owned. Do not run `ddx bead update <bead-id> --claim`, `ddx bead update <bead-id> --status <status>`, `ddx bead update <bead-id> --unclaim`, or `ddx bead close <bead-id>`. Step 0 still allows `ddx bead create`, `ddx bead dep add`, and `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. - If you cannot finish, write `no_changes_rationale.txt` under the bead metadata `bundle` path before exiting. No commit or rationale \u21d2 DDx records `no_evidence_produced`. ## no_changes contract The `no_changes_rationale.txt` file under the bead metadata `bundle` path must contain one of: - `verification_command: <cmd>` \u2014 repo cwd; exit 0 closes, nonzero rejects. - `status: open` + `reason: <retryable>` \u2014 open, smart retry. - `status: proposed` + `reason: <operator needed>` \u2014 operator lane. - `status: blocked` + `reason: <external blocker>` \u2014 blocked lane. No pseudo-statuses. Bare rationales and `status: needs_investigation` are rejected. For orchestrator decomposition, add `orchestrator_action: decompose` alongside `status: open`. ## Reports Reports go under the bead metadata `bundle` path in `.ddx/executions/`. **Never write reports to `/tmp` or outside the repo**. Use a named in-repo path when given; otherwise write `<short-name>.md` there. Commit it with the code. ## Mode and overrides DDX_MODE=bead_execution: edit code/docs for bead AC. Only broad queue-steward default is overridden; tracker, merge-policy, verification, safety stay active. Bead description/AC override CLAUDE.md, AGENTS.md, and defaults. ## Review gate - The review is a gate, not an escape hatch \u2014 meet every AC in this pass. - Address every BLOCKING `<review-findings>` item; do not declare `no_changes` with blocking findings open. ## Constraints - Work only inside this execution worktree. - Keep `.ddx/executions/` intact \u2014 DDx uses it as execution evidence. - **Never run `ddx init`** \u2014 the workspace is initialized. - Do not modify files outside the bead's named scope. - Do not rewrite CLAUDE.md, AGENTS.md, or other instruction files unless the bead asks. ## When the work is done After the commit succeeds and every AC is verified, stop. Return control to the orchestrator.\n \n \n Fix S3 cold-tier timeout-cancel feedback loop: configurable attempt timeout for large WAL segment uploads\n \nS3 cold-tier writes against Garage are entering a self-reinforcing failure loop. The proximate cause is that `S3ObjectStore::with_retry` (`crates/niflheim-object-store/src/s3/store.rs:233`) wraps every attempt in `tokio::time::timeout(self.config.attempt_timeout, f())`. When the timer fires, tokio **drops the inner future** \u2014 and the inner future is the in-flight `aws-sdk-s3` `PutObject` call. Dropping a hyper request mid-body teardowns the TCP connection while the request body is still being streamed. Confirmed from the Garage side: 100% of last-hour warnings on `eldir.azgaard.home:3900` are `WARN garage_api_common::generic_server: Response: error 500 Internal Server Error, Internal error (Hyper error): error reading a body from connection` \u2014 100% sourced from this niflheim node (192.168.2.118). 285 PUT / 79 DELETE / 32 GET against `/niflheim-cold/wal/segment-NNNNNNNN-offN-N.wal` in the same window. Garage itself is healthy (4 TB free, "fully operational", 4.75\u00d7 compression on data, RPC and admin sockets bound and responsive). **Why it triggers** - `S3Config::default().attempt_timeout = Duration::from_secs(60)` (`s3/config.rs:40`). - WAL segments are 1 GiB (`segment_seal_bytes = 1073741824` in the sindri-dev `niflheim.toml`); 60 s to PUT 1 GiB requires sustained ~17 MB/s end-to-end. Under any contention (concurrent PUTs, ZFS background work on Garage, Garage GC) the budget is missed. - Timeout fires \u2192 future cancelled \u2192 connection torn down \u2192 Garage records 500 \u2192 `is_transient_sdk_error` returns true \u2192 retry up to `max_retries=3` \u2192 same fate \u2192 4 attempts per segment all fail. - Each cancelled attempt leaves bytes in niflheim's kernel send buffer (~100 MB across ~63 concurrent stuck sockets observed live) and opens new connections rather than waiting for the prior one to drain. - Every retry-WARN line is exported by the file telemetry exporter, contributing materially to a 810 GB on-disk OTel volume in the sindri-dev install \u2014 directly motivating the sibling bead `niflheim-280de9c9` (rotation). **Candidate approaches** \u2014 pick during execution, document choice: 1. **Plumb `attempt_timeout` and `total_deadline` through `niflheim.toml`** under `[storage]` (e.g., `s3_attempt_timeout_secs`, `s3_total_deadline_secs`) and raise defaults to something realistic for 1 GiB segments (e.g., 600 s / 1800 s). Minimal code change; lets operators tune without a rebuild. 2. **Make `attempt_timeout` proportional to expected body size** \u2014 compute per-call based on segment/chunk bytes (e.g., `base + bytes / min_throughput`). Removes the operator-tuning burden but harder to bound correctly. 3. **Switch the WAL `put_object` paths to S3 multipart upload** (`UploadPart` + `CompleteMultipartUpload`). Each part has its own retry budget; on part failure the SDK can resume without re-uploading the whole body. This is the right long-term fix for objects \u2265 ~100 MiB. Larger change; touches `crates/niflheim-object-store/src/s3/wal_chunk_store_impl.rs` and the chunk-keyed coalesce path. 4. **Graceful-cancel** \u2014 when `with_retry` times out, instead of dropping the future, issue `AbortMultipartUpload` (or `Close` the underlying connection cleanly) so Garage doesn't observe a mid-body teardown. Helps server-side bookkeeping even when another fix is the primary remedy. Approaches (1) and (3) are non-overlapping \u2014 (1) is a quick win, (3) is the structural fix. The expected delivery is **(1) first as a hotfix**, then (3) as a follow-up if multipart is judged worth the churn. **In-scope files (for approach 1):** - `crates/niflheim-object-store/src/s3/config.rs` (defaults; optional builders already exist) - `crates/niflheim-object-store/src/wal_runtime.rs:112` (read new fields from `StorageConfig`, call `with_attempt_timeout` / `with_total_deadline`) - `crates/niflheim-core/src/config/storage.rs` (add the two new fields with Serde defaults preserving current behavior) - New tests covering the wiring (config \u2192 S3Config) and a unit test asserting that with a large `attempt_timeout` an in-flight upload does **not** get dropped before completing \u2014 use a mock `S3 Client` or a slow `tokio::time` controlled future. **Out-of-scope (file separately if needed):** - OTel file rotation (`niflheim-280de9c9` already covers it). - Operator action to truncate the existing 810 GB of debris. - Garage-side tuning (the server is healthy; no action needed there). - Reducing `segment_seal_bytes` \u2014 that's a runtime config change the operator can do today, not a code change. **Why not "just bump the default in config.rs":** because the right budget is workload-dependent (1 GiB segments need \u2265 5 min on a contended LAN; a future deployment with 256 MiB segments would be over-provisioned at 5 min). Operator-tunable via TOML is the right ergonomics. **Rollback behavior:** New TOML fields are optional with Serde defaults matching today's hardcoded `Duration::from_secs(60) / Duration::from_secs(300)` \u2014 reverting is a config edit, not a binary roll.\n \n \n1. `cargo test -p niflheim-object-store --lib s3` passes, including a new test that asserts: a. `S3Config` populated from a `StorageConfig` with `s3_attempt_timeout_secs = 600` produces `attempt_timeout == Duration::from_secs(600)`. b. Omitting the new field preserves the legacy default (`Duration::from_secs(60)`). 2. `cargo test -p niflheim-core --lib config::storage` passes, including a round-trip test (`toml::from_str` \u2192 `toml::to_string` \u2192 equality) for the new fields. 3. `cargo build --workspace` succeeds, no new warnings introduced. 4. `cargo clippy -p niflheim-object-store -p niflheim-core -- -D warnings` passes. 5. `grep -E 's3_attempt_timeout_secs|s3_total_deadline_secs' crates/niflheim-core/src/config/storage.rs` returns the two new fields wired into the public struct. 6. End-to-end smoke (manual or scripted) on sindri-dev: with the new TOML knob set to `s3_attempt_timeout_secs = 600` and a restart, observe in `journalctl`/OTel logs that the `niflheim_object_store::s3::store` WARN rate for "attempt timed out" falls to ~0 over a 5-minute window with steady ingest.\n \n area:storage, area:wal, kind:reliability, spec:ADR-032, spec:ADR-051,

"claude-2026-05-28-execute-bead-instructions-you-ar-43c0b72fe3", + "source": "claude-code", + "prompt": "\n \nYou are executing one bead in an isolated DDx execution worktree. The bead's <description> and <acceptance> are the contract: every AC must be provably satisfied by a specific code, test, or file after your commit. ## Step 0: size check Too big if any holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs. - Description names multiple feature-sized pieces. - More than ~500 lines across ~5+ files in unrelated packages. - If the bead description exceeds 8000 bytes, use a split-first pass. - Auto-decomposition is capped at depth 2: root beads may split once, children once more; reject third-level splits with an explanation. If too big, decompose: 1. `ddx bead create` for each child (copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. 4. Write `no_changes_rationale.txt` under the bead metadata `bundle` path with child IDs, then stop. Decomposition alone is success. Do not mix it with implementation. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC to concrete evidence (test, file, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Run git/index mutations sequentially; do not use parallel tool calls for `git add`, `git commit`, or other staging/commit commands. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - If `lefthook run pre-commit` depends on staged files, rerun it after staging the exact commit set. A `no-staged-files` run is not acceptance evidence. - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - Current-bead lifecycle is orchestrator-owned. Do not run `ddx bead update <bead-id> --claim`, `ddx bead update <bead-id> --status <status>`, `ddx bead update <bead-id> --unclaim`, or `ddx bead close <bead-id>`. Step 0 still allows `ddx bead create`, `ddx bead dep add`, and `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. - If you cannot finish, write `no_changes_rationale.txt` under the bead metadata `bundle` path before exiting. No commit or rationale \u21d2 DDx records `no_evidence_produced`. ## no_changes contract The `no_changes_rationale.txt` file under the bead metadata `bundle` path must contain one of: - `verification_command: <cmd>` \u2014 repo cwd; exit 0 closes, nonzero rejects. - `status: open` + `reason: <retryable>` \u2014 open, smart retry. - `status: proposed` + `reason: <operator needed>` \u2014 operator lane. - `status: blocked` + `reason: <external blocker>` \u2014 blocked lane. No pseudo-statuses. Bare rationales and `status: needs_investigation` are rejected. For orchestrator decomposition, add `orchestrator_action: decompose` alongside `status: open`. ## Reports Reports go under the bead metadata `bundle` path in `.ddx/executions/`. **Never write reports to `/tmp` or outside the repo**. Use a named in-repo path when given; otherwise write `<short-name>.md` there. Commit it with the code. ## Mode and overrides DDX_MODE=bead_execution: edit code/docs for bead AC. Only broad queue-steward default is overridden; tracker, merge-policy, verification, safety stay active. Bead description/AC override CLAUDE.md, AGENTS.md, and defaults. ## Review gate - The review is a gate, not an escape hatch \u2014 meet every AC in this pass. - Address every BLOCKING `<review-findings>` item; do not declare `no_changes` with blocking findings open. ## Constraints - Work only inside this execution worktree. - Keep `.ddx/executions/` intact \u2014 DDx uses it as execution evidence. - **Never run `ddx init`** \u2014 the workspace is initialized. - Do not modify files outside the bead's named scope. - Do not rewrite CLAUDE.md, AGENTS.md, or other instruction files unless the bead asks. ## When the work is done After the commit succeeds and every AC is verified, stop. Return control to the orchestrator.\n \n \n Capture Sindri performance evidence for pipelined materialization\n \nRun the Step 2 Sindri verify on prism_stage1_v1 with N=4 after the pipelined queue change lands. Capture the throughput comparison against the Step 1-only baseline, peak VmRSS, and the journal/log excerpts that demonstrate overlapping build and merge execution. Write the evidence bundle under docs/helix/04-build/evidence/IP-010/perf/<ts>-step2-pipelining/ and note whether CPU remains below 60 percent while ingest lag still grows. Out of scope: code changes and the integration failure-isolation test.\n \n \n1. Evidence exists under docs/helix/04-build/evidence/IP-010/perf/<ts>-step2-pipelining/ with throughput comparison vs Step 1. 2. The evidence bundle records the peak VmRSS observed during the verify run. 3. The evidence bundle records the command output or logs needed to evaluate whether a partition-bucketing follow-up bead is required. 4. The evidence is committed in the repository.\n \n spec:SD-009, spec:SD-023, materialization, perf, sindri, prism, concurrency\n \n \n \n No governing references were pre-resolved.

recovery paths from SD-009 \u00a73.1.5 explicitly. Each is its own typed error or restage path: | Failure point | Detection | Action | |---|---|---| | Mid-IPC-append (writer crash before EOS) | Trailing partial message detected on read | Truncate at last valid message; consolidator resumes appending | | Mid-merge (no Delta commit) | `staging_consumed_extents` lacks the row for the merge attempt | Re-enqueue; merge re-runs against same extents | | Post-Delta-commit pre-bookmark | `staging_consumed_extents` row exists with delta_version \u2265 table version | Idempotent: write `Drained` manifest entry on recovery | | Post-bookmark pre-rotation | Manifest is `Drained` for some extents but not for new ones | Resume: append new extents, rotate when triggered | | Mid-compaction (Phase 3 only) | Compacted Parquet partial; manifest still `Drained` | Discard partial Parquet; retry compaction | | Disk full | StagingQuotaController hard pressure | SQLSTATE 53100 + propagate via WAL retention | | Corrupt staging file | CRC32C / IPC magic mismatch on read | Typed `StagingCorrupt` error; manifest entry quarantined; merge fails to dead-letter queue | NO recovery path is allowed to silently re-decode WAL into in-RAM RecordBatches. ## Non-goals - Compaction recovery (Phase 3 sibling). - Cross-tenant recovery prioritization (Phase 4). ## Acceptance 1. Each recovery path has a unit test exercising the trigger and validating the action. 2. Typed errors: `StagingError::CorruptFile`, `StagingError::PartialAppend`, `StagingError::ManifestStale`, etc. \u2014 enumerated and documented. 3. Integration test (with chaos harness from p2_chaos): kill-restart cycle through each path produces deterministic recovery. 4. SD-009 \u00a73.1.5 table updated to reference test names. 5. clippy + lefthook clean. ## Suite scripts/with-pinned-rust.sh cargo test -p niflheim-delta-writer --lib source::persistent::recovery && scripts/with-pinned-rust.sh cargo test -p niflheim-integration-tests staging::recovery ## Files touched crates/niflheim-delta-writer/src/source/persistent/recovery.rs (new) docs/helix/02-design/system-design/SD-009-pgwire-ddl-and-wal-delta-apply.md (test refs in \u00a73.1.5) ## Depends on p2_manifest, p2_persistent_source, p2_bookmarks_extent_identity.\n \n \nAll seven recovery paths have unit tests; typed errors enumerated; integration test through chaos harness deterministic; SD-009 \u00a73.1.5 refs tests.\n \n spec:SD-009, materialization, phase-2, recovery\n \n \n \n No governing references were pre-resolved. The bead description above is the primary contract. If it names files, specs, or prior beads, read those before editing. Ground decisions in what is already in the repository; do not guess.\n \n \nYou are executing one bead inside an isolated DDx execution worktree. The bead's <description> and <acceptance> are the completion contract \u2014 every AC must be provably satisfied by a specific code, test, or file you can point to after your commit. ## Step 0: size check The bead is too big when any of these holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs as separate top-level deliverables. - Description names multiple feature-sized sub-pieces. - More than ~500 lines across more than ~5 files in unrelated packages. If too big, decompose \u2014 do not attempt the work: 1. `ddx bead create` for each child slice (focused title, description, AC; copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'` so the decomposition is visible. 4. Write `.ddx/executions/20260504T011911-01515540/no_changes_rationale.txt` listing each child ID and slice, then stop. A clean decomposition is a successful attempt. Do not mix partial implementation with decomposition. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC against concrete evidence (test name, file path, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - If you cannot finish, write `.ddx/executions/20260504T011911-01515540/no_changes_rationale.txt` (what is done, what blocks, what a follow-up needs) before exiting. No commit and no rationale \u21d2 DDx records `no_evidence_produced`. A well-justified no_changes beats a bad commit. ## no_changes contract If you write `.ddx/executions/20260504T011911-01515540/no_changes_rationale.txt`, it MUST carry one of: - `verification_command: <one-line shell command>` \u2014 the loop runs it (cwd = project root, 60s); exit 0 closes the bead, non-zero rejects. - `status: needs_investigation` + `reason: <why>` \u2014 bead stays open for triage. Bare rationales ("nothing to do") are rejected. ## Reports Freestanding artifacts (investigation reports, findings docs) go under `.ddx/executions/20260504T011911-01515540/` (the per-attempt evidence directory under `.ddx/executions/`). **Never write reports to `/tmp` or any path outside the repository** \u2014 out-of-repo paths are invisible to the post-merge reviewer and cause BLOCK on missing evidence.

"source": "codex", + "prompt": "\n \nYou are executing one bead inside an isolated DDx execution worktree. The bead's <description> and <acceptance> are the completion contract \u2014 every AC must be provably satisfied by a specific code, test, or file you can point to after your commit. ## Step 0: size check Too big if any holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs as separate deliverables. - Description names multiple feature-sized sub-pieces. - More than ~500 lines across ~5+ files in unrelated packages. - If the bead description exceeds 8000 bytes, treat Step 0 as a split-first pass. - Auto-decomposition is capped at depth 2: root beads may split once, decomposed children once more; third-level splits must be rejected with an explanation. If too big, decompose \u2014 do not attempt the work: 1. `ddx bead create` for each child slice (copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'`. 4. Write `.ddx/executions/20260511T205211-729cd951/no_changes_rationale.txt` listing child IDs, then stop. A clean decomposition is a success. Do not mix implementation with decomposition. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC against concrete evidence (test name, file path, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - If you cannot finish, write `.ddx/executions/20260511T205211-729cd951/no_changes_rationale.txt` (what is done, what blocks, what a follow-up needs) before exiting. No commit and no rationale \u21d2 DDx records `no_evidence_produced`. A well-justified no_changes beats a bad commit. ## no_changes contract `.ddx/executions/20260511T205211-729cd951/no_changes_rationale.txt` must contain one: - `verification_command: <cmd>` \u2014 repo cwd; exit 0 closes, nonzero rejects. - `status: open` + `reason: <retryable>` \u2014 open, smart retry. - `status: proposed` + `reason: <operator needed>` \u2014 operator lane. - `status: blocked` + `reason: <external blocker>` \u2014 blocked lane. No pseudo-statuses. Bare rationales and `status: needs_investigation` reject. To request orchestrator decomposition, add `orchestrator_action: decompose` alongside `status: open`. ## Reports Freestanding artifacts (investigation reports, findings docs) go under `.ddx/executions/20260511T205211-729cd951/` (the per-attempt evidence directory under `.ddx/executions/`). **Never write reports to `/tmp` or any path outside the repository** \u2014 out-of-repo paths are invisible to the post-merge reviewer and cause BLOCK on missing evidence. If the bead names a specific in-repo path, use it; else default to `.ddx/executions/20260511T205211-729cd951/<short-name>.md`. Stage and commit the report alongside code. ## Mode and overrides DDX_MODE=bead_execution: edit code/docs for bead AC. Only broad queue-steward default is overridden; tracker, merge-policy, verification, safety stay active. Bead description/AC override CLAUDE.md, AGENTS.md, and project defaults. ## Review gate - The review is a gate, not an escape hatch \u2014 meet every AC in this pass. - Address every BLOCKING `<review-findings>` item; do not declare `no_changes` with blocking findings open. ## Constraints - Work only inside this execution worktree. - Keep `.ddx/executions/` intact \u2014 DDx uses it as execution evidence. - **Never run `ddx init`** \u2014 the workspace is initialized; running it corrupts the bead queue. - Do not modify files outside the bead's named scope. - Do not rewrite CLAUDE.md, AGENTS.md, or other project-instructions files unless the bead asks. ## When the work is done After the commit succeeds and every AC is verified, stop. Return control to the orchestrator \u2014 do not keep exploring or testing.\n \n \n Hot-path parquet compression knob: LZ4/uncompressed for staged commits (Option C)\n \n<governing>SD-011; bead niflheim-91115788 Option C</governing> <context> The bead niflheim-91115788 listed C as one of four candidate fixes: "Defer/disable ZSTD on the hot path \u2014 switch to LZ4 (lighter) or uncompressed (fastest). Trades disk space for merge throughput." This was not exercised in niflheim-91115788 because Option A alone did not move the pass criterion enough to validate (the merge_gate hang dominated; see niflheim-0a07cff5). After that hang is resolved, C becomes a throughput lever worth measuring. Current setting: parquet writer uses Compression::ZSTD(level=3) via StorageConfig::default(). At 100k rows \u00d7 300B = 30 MB per merge, ZSTD takes ~50-100 ms in isolation but contributes to the per-merge wall time when stacked with planning + commit. </context> ## Acceptance 1. Add an operator-facing knob in [storage] (or new [delta]) section of niflheim.toml controlling parquet compression. Values: zstd (default), lz4, snappy, none. 2. Wire through to default_parquet_writer_properties(). 3. Benchmark: with merge hang resolved, run sustained 32k\u00d7300B for 5 min under each compression setting and report per-merge wall time and data_dir delta MB. Choose the default that has the best throughput-per-byte-stored ratio. ## Out-of-scope - Per-table compression overrides (table-level parquet config). - Compaction/optimize-time recompression (separate compaction worker).\n \n \n \n \n \n \n No governing references were pre-resolved. The bead description above is the primary contract. If it names files, specs, or prior beads, read those before editing. Ground decisions in what is already in the repository; do not guess.\n \n\n", + "initial_state": { + "cwd": "/tmp/ddx-exec-wt/.execute-bead-wt-niflheim-de0d8081-20260511T205211-729cd951", + "git_ref":

tests/integration/src/staging/phase1/. Materialise the same 100k-row corpus once with staging_mode=memory and once with staging_mode=ephemeral_ipc.\n \n \nTRACEABILITY doc-comment maps test to AC-SD9-MEM-002.

The bead description above is the primary contract. If it names files, specs, or prior beads, read those before editing. Ground decisions in what is already in the repository; do not guess.\n \n \nYou are executing one bead inside an isolated DDx execution worktree. The bead's <description> and <acceptance> are the completion contract \u2014 every AC must be provably satisfied by a specific code, test, or file you can point to after your commit. ## Step 0: size check The bead is too big when any of these holds: - More than ~6 ACs spanning unrelated subsystems. - AC mixes design, implementation, integration tests, and docs as separate top-level deliverables. - Description names multiple feature-sized sub-pieces. - More than ~500 lines across more than ~5 files in unrelated packages. If too big, decompose \u2014 do not attempt the work: 1. `ddx bead create` for each child slice (focused title, description, AC; copy parent's labels and spec-id). 2. `ddx bead dep add <child-id> <parent-id>` to record edges. 3. `ddx bead update <parent-id> --notes 'decomposed into <child-ids>'` so the decomposition is visible. 4. Write `.ddx/executions/20260503T053909-71c99b44/no_changes_rationale.txt` listing each child ID and slice, then stop. A clean decomposition is a successful attempt. Do not mix partial implementation with decomposition. ## How to work - Read first. If the bead names files, specs, or prior beads, read them before editing \u2014 do not guess. - Cross-reference each AC against concrete evidence (test name, file path, function) before committing. If you cannot point at it, it is not done. - Run the project's test and lint commands before committing. **Do not commit red code** \u2014 fix failures first. - Stage with `git add <specific-paths>`; never `git add -A` (the worktree may have unrelated WIP). - Commit exactly once when green; conventional-commit subject ending with `[<bead-id>]`. Stop after the commit. - Do not modify files outside the bead's scope. - If you cannot finish, write `.ddx/executions/20260503T053909-71c99b44/no_changes_rationale.txt` (what is done, what blocks, what a follow-up needs) before exiting. No commit and no rationale \u21d2 DDx records `no_evidence_produced`. A well-justified no_changes beats a bad commit. ## no_changes contract If you write `.ddx/executions/20260503T053909-71c99b44/no_changes_rationale.txt`, it MUST carry one of: - `verification_command: <one-line shell command>` \u2014 the loop runs it (cwd = project root, 60s); exit 0 closes the bead, non-zero rejects. - `status: needs_investigation` + `reason: <why>` \u2014 bead stays open for triage. Bare rationales ("nothing to do") are rejected. ## Reports Freestanding artifacts (investigation reports, findings docs) go under `.ddx/executions/20260503T053909-71c99b44/` (the per-attempt evidence directory under `.ddx/executions/`). **Never write reports to `/tmp` or any path outside the repository** \u2014 out-of-repo paths are invisible to the post-merge reviewer and cause BLOCK on missing evidence. If the bead names a specific in-repo path, use it; else default to `.ddx/executions/20260503T053909-71c99b44/<short-name>.md`. Stage and commit the report alongside code. ## Bead overrides project defaults The bead description and AC override CLAUDE.md, AGENTS.md, and conservative project defaults (YAGNI, DOWITYTD, no-docs-unless-asked) in this worktree \u2014 write whatever the bead asks for. ## Review gate - The review is a gate, not an escape hatch \u2014 meet every AC in this pass. - Address every BLOCKING `<review-findings>` item; do not declare `no_changes` with blocking findings open. ## Constraints - Work only inside this execution worktree. - Keep `.ddx/executions/` intact \u2014 DDx uses it as execution evidence. - **Never run `ddx init`** \u2014 the workspace is initialized; running it corrupts the bead queue. - Do not modify files outside the bead's named scope. - Do not rewrite CLAUDE.md, AGENTS.md, or other project-instructions files unless the bead asks. ## When the work is done After the commit succeeds and every AC is verified, stop. Return control to the orchestrator \u2014 do not keep exploring or testing.\n \n\n", + "initial_state": { + "cwd": "/tmp/ddx-exec-wt/.execute-bead-wt-niflheim-73303348-20260503T053909-71c99b44", +

`easel/docker/multi-arch-prebuild`. The commit *messages* match one-for-one but the SHAs differ, so this looks like a local rebase that hasn't been force-pushed. Needs reconciling before push.\n\n**Uncommitted work in submodule** `dflash/deps/llama.cpp`:\n- Submodule HEAD is detached at `ce3919b` (newer than the parent's recorded `dad4f26`)\n- 82 added lines in `ggml/src/ggml-cuda/fattn.cu` are uncommitted inside the submodule\n- This is real work that would be lost if the submodule is reset. Not associated with the docker/multi-arch-prebuild commits in messaging \u2014 it looks orphaned here.\n\n**Untracked files (all dated May 14, ~a year ago)** that belong to a different line of work \u2014 decode-goal / max-ctx experiments:\n- `dflash/baselines/` \u2014 ~20 JSON result files + `loop_decode_goal/` + summary docs\n- `dflash/docs/GOAL_decode_tree_verify_max_ctx.md`\n- `dflash/scripts/start_server.sh`, `dflash/scripts/decode_goal_retry_loop.sh`\n\nThese match the description of `stash@{0}: On integration/props-uv: decode-goal wip + baselines/docs/decode_goal_retry_loop`. They likely got dragged here when you switched branches.\n\n**Stashes** \u2014 both belong to other branches:\n- `stash@{0}` integration/props-uv \u2014 decode-goal wip\n- `stash@{1}` feat/setup-results-uv \u2014 pre-rebase snapshot\n\n**`.claude/`** is just harness worktree state \u2014 ignorable.\n\n**My recommendation**: three separate concerns to capture before doing anything destructive \u2014\n1. The submodule `fattn.cu` changes (82 lines) \u2014 figure out which branch they belong to and commit there.\n2. The May-14 decode-goal artifacts \u2014 these look like work that belongs on `integration/props-uv` (or successor), not here. Move/commit there or confirm `stash@{0}` already covers them.\n3. The 5-vs-6 branch divergence \u2014 decide rebase-and-force-push vs. merge before pushing.\n\nWant me to dig into any of these (e.g., diff the submodule change, compare untracked files against `stash@{0}`, or diff the local vs. remote commits)?" + }, + { + "role": "user", + "content": "This is strange.

`easel/docker/multi-arch-prebuild`. The commit *messages* match one-for-one but the SHAs differ, so this looks like a local rebase that hasn't been force-pushed. Needs reconciling before push.\n\n**Uncommitted work in submodule** `dflash/deps/llama.cpp`:\n- Submodule HEAD is detached at `ce3919b` (newer than the parent's recorded `dad4f26`)\n- 82 added lines in `ggml/src/ggml-cuda/fattn.cu` are uncommitted inside the submodule\n- This is real work that would be lost if the submodule is reset. Not associated with the docker/multi-arch-prebuild commits in messaging \u2014 it looks orphaned here.\n\n**Untracked files (all dated May 14, ~a year ago)** that belong to a different line of work \u2014 decode-goal / max-ctx experiments:\n- `dflash/baselines/` \u2014 ~20 JSON result files + `loop_decode_goal/` + summary docs\n- `dflash/docs/GOAL_decode_tree_verify_max_ctx.md`\n- `dflash/scripts/start_server.sh`, `dflash/scripts/decode_goal_retry_loop.sh`\n\nThese match the description of `stash@{0}: On integration/props-uv: decode-goal wip + baselines/docs/decode_goal_retry_loop`. They likely got dragged here when you switched branches.\n\n**Stashes** \u2014 both belong to other branches:\n- `stash@{0}` integration/props-uv \u2014 decode-goal wip\n- `stash@{1}` feat/setup-results-uv \u2014 pre-rebase snapshot\n\n**`.claude/`** is just harness worktree state \u2014 ignorable.\n\n**My recommendation**: three separate concerns to capture before doing anything destructive \u2014\n1. The submodule `fattn.cu` changes (82 lines) \u2014 figure out which branch they belong to and commit there.\n2. The May-14 decode-goal artifacts \u2014 these look like work that belongs on `integration/props-uv` (or successor), not here. Move/commit there or confirm `stash@{0}` already covers them.\n3.

Triage:\n\n## Stuff to capture (real, unsaved work)\n\n### 1. Submodule `fattn.cu` change \u2014 UNCOMMITTED, ORPHANED\n- Submodule HEAD = `ce3919b` which parent commit `75aa015` already records, so the pointer is fine.\n- But there's an uncommitted 82-line addition in `dflash/deps/llama.cpp` `ggml/src/ggml-cuda/fattn.cu` that **isn't on any submodule branch** (origin/feat/turbo-wht-strided-fused-quantize, luce-dflash, laguna-arch, pr10-tq3-dispatch-fix). This is orphaned work \u2014 worth a look before anything else.\n\n### 2. May-14 untracked files (only here + stash@{0})\n- `dflash/baselines/` (~20 timing/scaling JSONs + `loop_decode_goal/` + summary md)\n- `dflash/docs/GOAL_decode_tree_verify_max_ctx.md`\n- `dflash/scripts/decode_goal_retry_loop.sh`, `dflash/scripts/start_server.sh`\n\nThese don't exist in **any** branch. They match `stash@{0}: integration/props-uv: decode-goal wip + baselines/docs/decode_goal_retry_loop`. If they're still useful (decode-goal experiments), they need a home. If just artifacts, drop them.\n\n## Stuff that's almost certainly redundant\n\n### 3. Local `integration/props-uv-squared-clean` (15 commits ahead of easel/clean)\nThe 15 commits are the *original* versions of features bragi has since rebased on top of new main:\n- `feat(dflash): /props endpoint`, `Docker bootstrap`, `autotune & benchmark suites`, `profile snapshots & ds4 eval`, `thinking budget split`, etc.\n- All these names map 1:1 to content now present in easel/clean's tip `84ddd04 add benchmark and profile evidence suite` (plus its parents). Bragi appears to have squashed/restructured.\n- `git cherry` reports them as `+` (not patch-identical), so it's a restructure not a fast-forward.\n- **Recommendation**: confirm with a content diff against easel/clean, then reset local to easel/clean.\n\n### 4. Other branches (unique-commit count vs easel/clean + easel/main)\n| Branch | Unique | Verdict |\n|---|---|---|\n| `backup/...pre-rebase-20260517` | 41 | snapshot before squashing \u2014 keep until clean stack lands publicly, then delete |\n| `integration/props-uv` | 25 | predecessor of squared-clean; superseded |\n| `backup/...pre-collapse` | 14 | another pre-rebase snapshot |\n| `bench-agent-loop-faithful-replay` | 8 | tip is `fix(cuda): sync device before cuMem pool extension via llama.cpp submodule` \u2014 **worth checking**, might overlap with the orphaned `fattn.cu` change |\n| `integration/props-uv-squared` | 6 | intermediate |\n| `backup/...before-20260518-cleanup` | 5 | snapshot |\n| `feat/props-endpoint` | 2 | superseded |\n| `feat/bench-server` | 1 | `b7a20d5 feat(scripts): add server benchmark utility` \u2014 single commit, may already be in the suite |\n\n### 5. Stashes\n- `stash@{0}` \u2014 matches the May-14 untracked files; redundant if files are still on disk, **unless** the stash contains different/newer versions.\n- `stash@{1}` \u2014 pre-rebase snapshot for `feat/setup-results-uv` (branch no longer exists locally; remote at `easel/feat/setup-results-uv` from 2026-04-29). Almost certainly safe to drop.\n\n### 6. Worktrees \u2014 15+ `/tmp/lbh-*` worktrees marked prunable\nMost are dead exploration worktrees. `git worktree prune` after verifying.\n\n## The \"splittable stack\" on easel/clean\n\nThe user-authored features that bragi has stacked on top of main (filtering out merge commits and PR merges from upstream main), in dependency order from oldest to newest:\n1. `feat(dflash): add llama-compatible /props endpoint`\n2. `feat(lucebox): add Docker bootstrap and host CLI`\n3. `feat(lucebox): add autotune and benchmark suites`\n4. `feat(lucebox): add profile snapshots and ds4 eval export`\n5. `docs(snapshot): capture sindri profile baseline`\n6. `feat(server,bench): split thinking budget from reply budget (ds4-style)` + ds4 fixes/refactors\n7. `build(docker): split COPY by churn rate`\n8. `feat(lucebox): allow release-candidate image tags`\n9. `feat(lucebox): add release CLI and Docker prebuilds`\n10. `feat(dflash): align server props and thinking controls`\n11. `feat(lucebox): add benchmark and profile evidence suite`\n\nThose 11 are clean split candidates (probably 4\u20136 PRs after grouping: /props, Docker/release, bench/autotune, ds4 eval/thinking, evidence).\n\n---\n\n**Before I act**, I'd like to confirm direction.

"[tool result] worktrees" + }, + { + "role": "assistant", + "content": "Here's the state of this worktree:\n\n**Branch divergence** \u2014 `docker/multi-arch-prebuild` is 5 ahead / 6 behind `easel/docker/multi-arch-prebuild`. The commit *messages* match one-for-one but the SHAs differ, so this looks like a local rebase that hasn't been force-pushed. Needs reconciling before push.\n\n**Uncommitted work in submodule** `dflash/deps/llama.cpp`:\n- Submodule HEAD is detached at `ce3919b` (newer than the parent's recorded `dad4f26`)\n- 82 added lines in `ggml/src/ggml-cuda/fattn.cu` are uncommitted inside the submodule\n- This is real work that would be lost if the submodule is reset. Not associated with the docker/multi-arch-prebuild commits in messaging \u2014 it looks orphaned here.\n\n**Untracked files (all dated May 14, ~a year ago)** that belong to a different line of work \u2014 decode-goal / max-ctx experiments:\n- `dflash/baselines/` \u2014 ~20 JSON result files + `loop_decode_goal/` + summary docs\n- `dflash/docs/GOAL_decode_tree_verify_max_ctx.md`\n- `dflash/scripts/start_server.sh`, `dflash/scripts/decode_goal_retry_loop.sh`\n\nThese match the description of `stash@{0}: On integration/props-uv: decode-goal wip + baselines/docs/decode_goal_retry_loop`. They likely got dragged here when you switched branches.\n\n**Stashes** \u2014 both belong to other branches:\n- `stash@{0}` integration/props-uv \u2014 decode-goal wip\n- `stash@{1}` feat/setup-results-uv \u2014 pre-rebase snapshot\n\n**`.claude/`** is just harness worktree state \u2014 ignorable.\n\n**My recommendation**: three separate concerns to capture before doing anything destructive \u2014\n1. The submodule `fattn.cu` changes (82 lines) \u2014 figure out which branch they belong to and commit there.\n2. The May-14 decode-goal artifacts \u2014 these look like work that belongs on `integration/props-uv` (or successor), not here. Move/commit there or confirm `stash@{0}` already covers them.\n3. The 5-vs-6 branch divergence \u2014 decide rebase-and-force-push vs. merge before pushing.\n\nWant me to dig into any of these (e.g., diff the submodule change, compare untracked files against `stash@{0}`, or diff the local vs. remote commits)?" + }, + { + "role": "user", + "content": "This is strange.

Those were never committed to any branch; they only live here and in `stash@{0}` (\"decode-goal wip + baselines/docs/decode_goal_retry_loop\" on `integration/props-uv`).\n\nA few things to clarify before I do anything:\n\n1. **Is \"bragi\"** a teammate, a dev box, or shorthand for another repo? If it's a remote machine, the benchmarks may have been pushed/scp'd there rather than committed \u2014 different recovery path.\n2. **Which benchmarks** do you mean \u2014 the lucebox bench/profile suite on `integration/props-uv-squared-clean` (which is safe on the remote), or the May-14 dflash decode-goal timing JSONs sitting untracked here (which exist only locally + in stash)?" + }, + { + "role": "user", + "content": "We need to get things cleaned up.

Triage:\n\n## Stuff to capture (real, unsaved work)\n\n### 1. Submodule `fattn.cu` change \u2014 UNCOMMITTED, ORPHANED\n- Submodule HEAD = `ce3919b` which parent commit `75aa015` already records, so the pointer is fine.\n- But there's an uncommitted 82-line addition in `dflash/deps/llama.cpp` `ggml/src/ggml-cuda/fattn.cu` that **isn't on any submodule branch** (origin/feat/turbo-wht-strided-fused-quantize, luce-dflash, laguna-arch, pr10-tq3-dispatch-fix). This is orphaned work \u2014 worth a look before anything else.\n\n### 2. May-14 untracked files (only here + stash@{0})\n- `dflash/baselines/` (~20 timing/scaling JSONs + `loop_decode_goal/` + summary md)\n- `dflash/docs/GOAL_decode_tree_verify_max_ctx.md`\n- `dflash/scripts/decode_goal_retry_loop.sh`, `dflash/scripts/start_server.sh`\n\nThese don't exist in **any** branch. They match `stash@{0}: integration/props-uv: decode-goal wip + baselines/docs/decode_goal_retry_loop`. If they're still useful (decode-goal experiments), they need a home. If just artifacts, drop them.\n\n## Stuff that's almost certainly redundant\n\n### 3. Local `integration/props-uv-squared-clean` (15 commits ahead of easel/clean)\nThe 15 commits are the *original* versions of features bragi has since rebased on top of new main:\n- `feat(dflash): /props endpoint`, `Docker bootstrap`, `autotune & benchmark suites`, `profile snapshots & ds4 eval`, `thinking budget split`, etc.\n- All these names map 1:1 to content now present in easel/clean's tip `84ddd04 add benchmark and profile evidence suite` (plus its parents). Bragi appears to have squashed/restructured.\n- `git cherry` reports them as `+` (not patch-identical), so it's a restructure not a fast-forward.\n- **Recommendation**: confirm with a content diff against easel/clean, then reset local to easel/clean.\n\n### 4. Other branches (unique-commit count vs easel/clean + easel/main)\n| Branch | Unique | Verdict |\n|---|---|---|\n| `backup/...pre-rebase-20260517` | 41 | snapshot before squashing \u2014 keep until clean stack lands publicly, then delete |\n| `integration/props-uv` | 25 | predecessor of squared-clean; superseded |\n| `backup/...pre-collapse` | 14 | another pre-rebase snapshot |\n| `bench-agent-loop-faithful-replay` | 8 | tip is `fix(cuda): sync device before cuMem pool extension via llama.cpp submodule` \u2014 **worth checking**, might overlap with the orphaned `fattn.cu` change |\n| `integration/props-uv-squared` | 6 | intermediate |\n| `backup/...before-20260518-cleanup` | 5 | snapshot |\n| `feat/props-endpoint` | 2 | superseded |\n| `feat/bench-server` | 1 | `b7a20d5 feat(scripts): add server benchmark utility` \u2014 single commit, may already be in the suite |\n\n### 5. Stashes\n- `stash@{0}` \u2014 matches the May-14 untracked files; redundant if files are still on disk, **unless** the stash contains different/newer versions.\n- `stash@{1}` \u2014 pre-rebase snapshot for `feat/setup-results-uv` (branch no longer exists locally; remote at `easel/feat/setup-results-uv` from 2026-04-29). Almost certainly safe to drop.\n\n### 6. Worktrees \u2014 15+ `/tmp/lbh-*` worktrees marked prunable\nMost are dead exploration worktrees. `git worktree prune` after verifying.\n\n## The \"splittable stack\" on easel/clean\n\nThe user-authored features that bragi has stacked on top of main (filtering out merge commits and PR merges from upstream main), in dependency order from oldest to newest:\n1. `feat(dflash): add llama-compatible /props endpoint`\n2. `feat(lucebox): add Docker bootstrap and host CLI`\n3. `feat(lucebox): add autotune and benchmark suites`\n4. `feat(lucebox): add profile snapshots and ds4 eval export`\n5. `docs(snapshot): capture sindri profile baseline`\n6. `feat(server,bench): split thinking budget from reply budget (ds4-style)` + ds4 fixes/refactors\n7. `build(docker): split COPY by churn rate`\n8. `feat(lucebox): allow release-candidate image tags`\n9. `feat(lucebox): add release CLI and Docker prebuilds`\n10. `feat(dflash): align server props and thinking controls`\n11. `feat(lucebox): add benchmark and profile evidence suite`\n\nThose 11 are clean split candidates (probably 4\u20136 PRs after grouping: /props, Docker/release, bench/autotune, ds4 eval/thinking, evidence).\n\n---\n\n**Before I act**, I'd like to confirm direction.

Submodule `fattn.cu` (82 lines) \u2014 **flash-attention dispatch tracer**\nPure instrumentation: prints kernel choice, Q/K/V shapes/types/strides, and mask shape per FA call. Gated by env vars:\n- `DFLASH27B_FA_TRACE=1` \u2014 enable\n- `DFLASH27B_FA_TRACE_MAX` \u2014 line limit (default 200)\n\nThis is a **debugging tool for the decode-goal max-ctx investigation** (matches the May-14 GOAL doc). Not a fix \u2014 a probe. Not on any submodule branch, not on `bench-agent-loop-faithful-replay` (that branch's submodule fixes are unrelated cuMem/TQ3 work, and its tip is already merged into our current submodule HEAD).\n\n**Recommendation**: Save it on a feature branch inside the submodule (`feat/fa-dispatch-trace`) so it's recoverable, then reset the submodule. Or discard if the investigation is dead.\n\n### 2. Stash@{0} \u2260 the untracked May-14 files\nImportant correction to my earlier read: `git stash` only captured **tracked-file modifications** at the time:\n- `dflash/scripts/bench_llm.py` (+389/-20)\n- `dflash/test/test_dflash.cpp` (+21/-20)\n\nThe untracked files (`start_server.sh`, `decode_goal_retry_loop.sh`, GOAL doc, `dflash/baselines/`) **were never in the stash**. They exist **only on disk here, in no other branch or stash**. If you delete them, they're gone.\n\nThe stash's bench_llm.py mods (+389 lines \u2014 substantial) look like real bench work that may or may not have been incorporated into the easel/clean bench suite. Worth a diff before dropping `stash@{0}`.\n\n### 3. Local clean is *older* content, not unique content\n- Diff: 7,371 insertions / 976 deletions across 165 files between local and easel clean.\n- **Zero files exist only on local**. Easel adds 12 files (gemma4 backend, disk_prefix_cache, tool_hint, gguf_mmap, etc. \u2014 all from rebased main).\n- Key user-authored files differ in size, with easel always being the larger/newer version:\n - `lucebox.sh` +9/-5\n - `bench_http_capability.py` +55/-31\n - `bench_ds4_eval.py` +10/-10\n - `thinking-budget.md` +103/-7\n - `Dockerfile` +5/-0\n- Conclusion: **resetting local to easel/clean loses nothing.** Bragi's branch is strictly newer.\n\n### 4. Additional flag: `bench-agent-loop-faithful-replay`\nThat branch's 8 unique commits are **faithful-replay bench work** (prefix cache phase A/B, transcript replay, empty-response repro, TTFT). The tip's submodule bump (`cuMem pool extension fix`) is already incorporated into our current submodule via easel PR #4 \u2014 *but* the prefix-cache bench scripts themselves are unique and don't appear in easel/clean's bench suite. Worth keeping or porting before deletion.\n\n---\n\n## Updated cleanup plan\n\nBefore destructive operations, two more decisions:\n\n[Tool: AskUserQuestion({\"questions\": [{\"question\": \"fattn.cu tracer: save it on a submodule branch first, or discard?\", \"header\": \"FA tracer\", \"multiSelect\": false, \"options\": [{\"label\": \"Save as feat/fa-dispatch-trace in submodule\", \"description\": \"Commit it inside dflash/deps/llama.cpp on a new branch so it's recoverable if decode-goal work resumes.\"}, {\"label\": \"Discard\", \"description\": \"Reset the submodule tree.

Reusable as historical reference.\n- **`decode_goal_retry_loop.sh`**: generic overnight-benchmark orchestrator (locking, GPU-busy detection, iteration state). Reusable beyond decode-goal.\n- **`start_server.sh`**: dflash_server launcher with each flag's rationale documented from the sweeps. Lower-level than `lucebox.sh`/lucebox CLI.\n\nEasel/clean **directionally addressed the same problem** with different fixes:\n- `c4a7ba6 gemma4: implement G5 SWA ring-buffer, G6 fa_window, G3 compress`\n- `570a71f server: add --fa-window CLI flag to dflash_server`\n- `2ee7462 fix(scripts): auto-fit --max-ctx to prompt size`\n- `c1bd053 fix(server): sync max_ctx between HTTP server and backend KV cache`\n\nSo the GOAL doc's *acceptance criteria* (\u22650.75x fitted decode at max_ctx=131072) probably haven't been re-measured against the new stack. The baselines remain valuable as a \"before\" reference.\n\n**Recommendation**: commit the May-14 files to a new branch `wip/decode-goal-may14` off `integration/props-uv` (where they originated per the stash description). They don't belong on easel/clean \u2014 different architecture \u2014 but they shouldn't die untracked either.\n\n### Stash@{0} bench_llm.py: **stash is BIGGER than easel/clean**\n- Stash version: 759 lines\n- Easel/clean version: 505 lines\n- The +389 lines in the stash were **dropped** in bragi's rewrite \u2014 likely moved into `lucebox/lucebox/profile.py` / `autotune.py` / `dflash/scripts/lucebox_bench.py` as part of the bench-suite refactor.\n\nYou probably want to confirm those 254 lost lines really were ported (not just discarded) before dropping the stash.

Should be a separate piece of work off easel/clean.\n\n2. **`docker/multi-arch-prebuild` branch divergence** \u2014 local is 5 ahead / 6 behind `easel/docker/multi-arch-prebuild`; commit messages match but SHAs differ (looks like a local rebase that wasn't force-pushed). Plus the submodule pointer mismatch: this branch records `dad4f26`, the working tree shows `ce3919b`. Needs a decision (bump submodule pointer? rebase + force-push?).\n\n3. **Stack split on `easel/integration/props-uv-squared-clean`** \u2014 you mentioned splitting the 11-feature stack into separate PRs. Candidate groupings:\n - `feat(dflash): /props endpoint` (foundation)\n - `feat(lucebox): Docker bootstrap + host CLI` + `feat(lucebox): release CLI and Docker prebuilds` + `build(docker): split COPY by churn` + `feat(lucebox): release-candidate image tags` (Docker / lucebox shell)\n - `feat(lucebox): autotune and benchmark suites` + `feat(lucebox): profile snapshots and ds4 eval export` + `docs(snapshot): sindri profile baseline` (bench / profile core)\n - `feat(server,bench): split thinking budget from reply budget` + `fix(ds4): align single-case eval` + `chore(lucebox): remove stale snapshot and ds4 leftovers` + `fix(bench): declare ds4 re-export surface` + `refactor(bench): factor ds4_eval` + `fix(bench-capability): unconditional thinking budget` (ds4 / thinking budget)\n - `feat(dflash): align server props and thinking controls` (server alignment)\n - `feat(lucebox): benchmark and profile evidence suite` (evidence)\n - `test(lucebox): isolated wrapper sandbox check` + `chore(lucebox): remove stale branch noise` (housekeeping)\n\n4. **30 local branches still around** \u2014 many likely stale (more backup/*, older feat/*, repro/*, scratch/*, chore/*). Quick triage offer if you want.\n\n5. **GOAL doc acceptance criteria not re-measured** \u2014 the `\u22650.75x fitted decode at max_ctx=131072` target was never verified against bragi's new SWA ring-buffer + fa_window + auto-fit-max-ctx fixes. Could be a small follow-up to either retire the GOAL or confirm closure.\n\nWant me to tackle any of these next?" + }, + { + "role": "user", + "content": "So is everything at least checked in?

`easel/docker/multi-arch-prebuild`. The commit *messages* match one-for-one but the SHAs differ, so this looks like a local rebase that hasn't been force-pushed. Needs reconciling before push.\n\n**Uncommitted work in submodule** `dflash/deps/llama.cpp`:\n- Submodule HEAD is detached at `ce3919b` (newer than the parent's recorded `dad4f26`)\n- 82 added lines in `ggml/src/ggml-cuda/fattn.cu` are uncommitted inside the submodule\n- This is real work that would be lost if the submodule is reset. Not associated with the docker/multi-arch-prebuild commits in messaging \u2014 it looks orphaned here.\n\n**Untracked files (all dated May 14, ~a year ago)** that belong to a different line of work \u2014 decode-goal / max-ctx experiments:\n- `dflash/baselines/` \u2014 ~20 JSON result files + `loop_decode_goal/` + summary docs\n- `dflash/docs/GOAL_decode_tree_verify_max_ctx.md`\n- `dflash/scripts/start_server.sh`, `dflash/scripts/decode_goal_retry_loop.sh`\n\nThese match the description of `stash@{0}: On integration/props-uv: decode-goal wip + baselines/docs/decode_goal_retry_loop`. They likely got dragged here when you switched branches.\n\n**Stashes** \u2014 both belong to other branches:\n- `stash@{0}` integration/props-uv \u2014 decode-goal wip\n- `stash@{1}` feat/setup-results-uv \u2014 pre-rebase snapshot\n\n**`.claude/`** is just harness worktree state \u2014 ignorable.\n\n**My recommendation**: three separate concerns to capture before doing anything destructive \u2014\n1. The submodule `fattn.cu` changes (82 lines) \u2014 figure out which branch they belong to and commit there.\n2. The May-14 decode-goal artifacts \u2014 these look like work that belongs on `integration/props-uv` (or successor), not here. Move/commit there or confirm `stash@{0}` already covers them.\n3. The 5-vs-6 branch divergence \u2014 decide rebase-and-force-push vs. merge before pushing.\n\nWant me to dig into any of these (e.g., diff the submodule change, compare untracked files against `stash@{0}`, or diff the local vs. remote commits)?" + }, + { + "role": "user", + "content": "This is strange.

Local `integration/props-uv-squared-clean` (15 commits ahead of easel/clean)\nThe 15 commits are the *original* versions of features bragi has since rebased on top of new main:\n- `feat(dflash): /props endpoint`, `Docker bootstrap`, `autotune & benchmark suites`, `profile snapshots & ds4 eval`, `thinking budget split`, etc.\n- All these names map 1:1 to content now present in easel/clean's tip `84ddd04 add benchmark and profile evidence suite` (plus its parents). Bragi appears to have squashed/restructured.\n- `git cherry` reports them as `+` (not patch-identical), so it's a restructure not a fast-forward.\n- **Recommendation**: confirm with a content diff against easel/clean, then reset local to easel/clean.\n\n### 4. Other branches (unique-commit count vs easel/clean + easel/main)\n| Branch | Unique | Verdict |\n|---|---|---|\n| `backup/...pre-rebase-20260517` | 41 | snapshot before squashing \u2014 keep until clean stack lands publicly, then delete |\n| `integration/props-uv` | 25 | predecessor of squared-clean; superseded |\n| `backup/...pre-collapse` | 14 | another pre-rebase snapshot |\n| `bench-agent-loop-faithful-replay` | 8 | tip is `fix(cuda): sync device before cuMem pool extension via llama.cpp submodule` \u2014 **worth checking**, might overlap with the orphaned `fattn.cu` change |\n| `integration/props-uv-squared` | 6 | intermediate |\n| `backup/...before-20260518-cleanup` | 5 | snapshot |\n| `feat/props-endpoint` | 2 | superseded |\n| `feat/bench-server` | 1 | `b7a20d5 feat(scripts): add server benchmark utility` \u2014 single commit, may already be in the suite |\n\n### 5. Stashes\n- `stash@{0}` \u2014 matches the May-14 untracked files; redundant if files are still on disk, **unless** the stash contains different/newer versions.\n- `stash@{1}` \u2014 pre-rebase snapshot for `feat/setup-results-uv` (branch no longer exists locally; remote at `easel/feat/setup-results-uv` from 2026-04-29). Almost certainly safe to drop.\n\n### 6. Worktrees \u2014 15+ `/tmp/lbh-*` worktrees marked prunable\nMost are dead exploration worktrees. `git worktree prune` after verifying.\n\n## The \"splittable stack\" on easel/clean\n\nThe user-authored features that bragi has stacked on top of main (filtering out merge commits and PR merges from upstream main), in dependency order from oldest to newest:\n1. `feat(dflash): add llama-compatible /props endpoint`\n2. `feat(lucebox): add Docker bootstrap and host CLI`\n3. `feat(lucebox): add autotune and benchmark suites`\n4. `feat(lucebox): add profile snapshots and ds4 eval export`\n5. `docs(snapshot): capture sindri profile baseline`\n6. `feat(server,bench): split thinking budget from reply budget (ds4-style)` + ds4 fixes/refactors\n7. `build(docker): split COPY by churn rate`\n8. `feat(lucebox): allow release-candidate image tags`\n9. `feat(lucebox): add release CLI and Docker prebuilds`\n10. `feat(dflash): align server props and thinking controls`\n11. `feat(lucebox): add benchmark and profile evidence suite`\n\nThose 11 are clean split candidates (probably 4\u20136 PRs after grouping: /props, Docker/release, bench/autotune, ds4 eval/thinking, evidence).\n\n---\n\n**Before I act**, I'd like to confirm direction.

Submodule `fattn.cu` (82 lines) \u2014 **flash-attention dispatch tracer**\nPure instrumentation: prints kernel choice, Q/K/V shapes/types/strides, and mask shape per FA call. Gated by env vars:\n- `DFLASH27B_FA_TRACE=1` \u2014 enable\n- `DFLASH27B_FA_TRACE_MAX` \u2014 line limit (default 200)\n\nThis is a **debugging tool for the decode-goal max-ctx investigation** (matches the May-14 GOAL doc). Not a fix \u2014 a probe. Not on any submodule branch, not on `bench-agent-loop-faithful-replay` (that branch's submodule fixes are unrelated cuMem/TQ3 work, and its tip is already merged into our current submodule HEAD).\n\n**Recommendation**: Save it on a feature branch inside the submodule (`feat/fa-dispatch-trace`) so it's recoverable, then reset the submodule. Or discard if the investigation is dead.\n\n### 2. Stash@{0} \u2260 the untracked May-14 files\nImportant correction to my earlier read: `git stash` only captured **tracked-file modifications** at the time:\n- `dflash/scripts/bench_llm.py` (+389/-20)\n- `dflash/test/test_dflash.cpp` (+21/-20)\n\nThe untracked files (`start_server.sh`, `decode_goal_retry_loop.sh`, GOAL doc, `dflash/baselines/`) **were never in the stash**. They exist **only on disk here, in no other branch or stash**. If you delete them, they're gone.\n\nThe stash's bench_llm.py mods (+389 lines \u2014 substantial) look like real bench work that may or may not have been incorporated into the easel/clean bench suite. Worth a diff before dropping `stash@{0}`.\n\n### 3. Local clean is *older* content, not unique content\n- Diff: 7,371 insertions / 976 deletions across 165 files between local and easel clean.\n- **Zero files exist only on local**. Easel adds 12 files (gemma4 backend, disk_prefix_cache, tool_hint, gguf_mmap, etc. \u2014 all from rebased main).\n- Key user-authored files differ in size, with easel always being the larger/newer version:\n - `lucebox.sh` +9/-5\n - `bench_http_capability.py` +55/-31\n - `bench_ds4_eval.py` +10/-10\n - `thinking-budget.md` +103/-7\n - `Dockerfile` +5/-0\n- Conclusion: **resetting local to easel/clean loses nothing.** Bragi's branch is strictly newer.\n\n### 4. Additional flag: `bench-agent-loop-faithful-replay`\nThat branch's 8 unique commits are **faithful-replay bench work** (prefix cache phase A/B, transcript replay, empty-response repro, TTFT). The tip's submodule bump (`cuMem pool extension fix`) is already incorporated into our current submodule via easel PR #4 \u2014 *but* the prefix-cache bench scripts themselves are unique and don't appear in easel/clean's bench suite. Worth keeping or porting before deletion.\n\n---\n\n## Updated cleanup plan\n\nBefore destructive operations, two more decisions:\n\n[Tool: AskUserQuestion({\"questions\": [{\"question\": \"fattn.cu tracer: save it on a submodule branch first, or discard?\", \"header\": \"FA tracer\", \"multiSelect\": false, \"options\": [{\"label\": \"Save as feat/fa-dispatch-trace in submodule\", \"description\": \"Commit it inside dflash/deps/llama.cpp on a new branch so it's recoverable if decode-goal work resumes.\"}, {\"label\": \"Discard\", \"description\": \"Reset the submodule tree.

Reusable as historical reference.\n- **`decode_goal_retry_loop.sh`**: generic overnight-benchmark orchestrator (locking, GPU-busy detection, iteration state). Reusable beyond decode-goal.\n- **`start_server.sh`**: dflash_server launcher with each flag's rationale documented from the sweeps. Lower-level than `lucebox.sh`/lucebox CLI.\n\nEasel/clean **directionally addressed the same problem** with different fixes:\n- `c4a7ba6 gemma4: implement G5 SWA ring-buffer, G6 fa_window, G3 compress`\n- `570a71f server: add --fa-window CLI flag to dflash_server`\n- `2ee7462 fix(scripts): auto-fit --max-ctx to prompt size`\n- `c1bd053 fix(server): sync max_ctx between HTTP server and backend KV cache`\n\nSo the GOAL doc's *acceptance criteria* (\u22650.75x fitted decode at max_ctx=131072) probably haven't been re-measured against the new stack. The baselines remain valuable as a \"before\" reference.\n\n**Recommendation**: commit the May-14 files to a new branch `wip/decode-goal-may14` off `integration/props-uv` (where they originated per the stash description). They don't belong on easel/clean \u2014 different architecture \u2014 but they shouldn't die untracked either.\n\n### Stash@{0} bench_llm.py: **stash is BIGGER than easel/clean**\n- Stash version: 759 lines\n- Easel/clean version: 505 lines\n- The +389 lines in the stash were **dropped** in bragi's rewrite \u2014 likely moved into `lucebox/lucebox/profile.py` / `autotune.py` / `dflash/scripts/lucebox_bench.py` as part of the bench-suite refactor.\n\nYou probably want to confirm those 254 lost lines really were ported (not just discarded) before dropping the stash.

Should be a separate piece of work off easel/clean.\n\n2. **`docker/multi-arch-prebuild` branch divergence** \u2014 local is 5 ahead / 6 behind `easel/docker/multi-arch-prebuild`; commit messages match but SHAs differ (looks like a local rebase that wasn't force-pushed). Plus the submodule pointer mismatch: this branch records `dad4f26`, the working tree shows `ce3919b`. Needs a decision (bump submodule pointer? rebase + force-push?).\n\n3. **Stack split on `easel/integration/props-uv-squared-clean`** \u2014 you mentioned splitting the 11-feature stack into separate PRs. Candidate groupings:\n - `feat(dflash): /props endpoint` (foundation)\n - `feat(lucebox): Docker bootstrap + host CLI` + `feat(lucebox): release CLI and Docker prebuilds` + `build(docker): split COPY by churn` + `feat(lucebox): release-candidate image tags` (Docker / lucebox shell)\n - `feat(lucebox): autotune and benchmark suites` + `feat(lucebox): profile snapshots and ds4 eval export` + `docs(snapshot): sindri profile baseline` (bench / profile core)\n - `feat(server,bench): split thinking budget from reply budget` + `fix(ds4): align single-case eval` + `chore(lucebox): remove stale snapshot and ds4 leftovers` + `fix(bench): declare ds4 re-export surface` + `refactor(bench): factor ds4_eval` + `fix(bench-capability): unconditional thinking budget` (ds4 / thinking budget)\n - `feat(dflash): align server props and thinking controls` (server alignment)\n - `feat(lucebox): benchmark and profile evidence suite` (evidence)\n - `test(lucebox): isolated wrapper sandbox check` + `chore(lucebox): remove stale branch noise` (housekeeping)\n\n4. **30 local branches still around** \u2014 many likely stale (more backup/*, older feat/*, repro/*, scratch/*, chore/*). Quick triage offer if you want.\n\n5. **GOAL doc acceptance criteria not re-measured** \u2014 the `\u22650.75x fitted decode at max_ctx=131072` target was never verified against bragi's new SWA ring-buffer + fa_window + auto-fit-max-ctx fixes. Could be a small follow-up to either retire the GOAL or confirm closure.\n\nWant me to tackle any of these next?" + }, + { + "role": "user", + "content": "So is everything at least checked in?
