背景

实现 ZCode CLI 探针,为 pilot 集成 ZCode 链路的日志与 trace 采集能力。相关 issue: AGE-769

核心改动

新增 ZCode 双源采集链路:

  • Hook processorassets/hooks/zcode-hook-processor.mjs + zcode-loongsuite-pilot-hook.sh — 通过 zcode 的 hook 机制实时采集 step/llm/tool 事件
  • Rollout inputsrc/inputs/zcode-rollout/zcode-rollout-input.ts — 解析 zcode rollout JSONL 离线重建 trace
  • Hook inputsrc/inputs/zcode-hook/zcode-hook-input.ts — hook 路径事件归一化
  • Shared helpersassets/hooks/zcode/{message-converter,state,transcript-parser}.mjs
  • Agent 配置agents.d/zcode.json + src/deployment/hook-strategy.ts 部署注入
  • Trace 校验规则docs/trace-validation-rules.json(移出 .gitignore 以纳入版本控制)

iter5 → iter6 9 ERROR 清零说明

iter5 validate-trace 报告 9 条 ERROR(详见附件 zcode-iter5-validate-trace-report.json)。根因集中在:

  1. matcher * regex 抛 SyntaxError → catch → false → hook 不 fire(改用 .*
  2. hook 路径未 emit gen_ai.input.messages / gen_ai.output.messages
  3. SQLite turn_usage 时序晚于 runStopHooks,turn_usage=0

iter6 修复后 validate-trace 0 ERROR / 108 WARN(均 SHOULD 级),详见 zcode-iter6-validate-trace-report.json

准出证据(5 条全绿)

Ref: AGE-769
traceId: 7ee0402d0bdd471395bb64e988d699f1

Implements ZCode trace collection via two parallel sources:
- Hook processor: shell hook + JS processor for live step/llm/tool events
- Rollout input: parses zcode rollout JSONL for offline reconstruction

Covers iter5→iter6 validate-trace cleanup (9 ERROR → 0 ERROR).
Validated with real zcode 0.15.0 CLI: 3 STEP + 3 TOOL (Read×2 + Bash×1).

  • performance: Baseline-skip on first install (byteOffset → EOF) prevents replaying history on pilot startup (spec §1.4).

Suggestions

  • The @ts-expect-error on the .mjs cross-import is pragmatic given no type declarations exist; consider adding a minimal .d.ts shim for toW3CTraceId/deriveSpanId in a follow-up to remove the suppression.
  • The 1ms placeholder tool-span duration is documented and intentional, but worth a brief inline note in the OTLP flusher that these synthetic durations should not be aggregated into latency SLOs.

Summary

Re-reviewed PR #136 after new commit ceb70cf3 ("fix: stable per-line step.id derivation + non-overlapping STEP time windows"). The commit replaces the fragile state-dependent nextTurnIndex counter with requestId-based step.id derivation and fixes STEP time window overlaps — both well-reasoned improvements.

However, CI is failing on all Node versions: the test hook-processor.test.mjs:130 reads probe-hook-trace.log via fs.readFileSync, but this fixture file is not committed in the PR. This causes an ENOENT error and breaks the build.

Additionally, CLA is not signed — this PR cannot be approved/merged until the contributor signs the CLA (see reminder above). Per policy, only COMMENT is posted even though the code changes look solid.

Findings

  • [Critical] tests/unit/hooks/zcode/hook-processor.test.mjs:130 — Missing fixture file probe-hook-trace.log causes CI failure (ENOENT)
  • [Info] src/inputs/zcode-rollout/zcode-rollout-input.ts:240 — Good improvement: requestId-based step.id eliminates state-dependent counter fragility
  • [Info] src/inputs/zcode-rollout/zcode-rollout-input.ts:310 — Non-overlapping STEP time windows fix is correct

Suggestions

  1. Commit the missing probe-hook-trace.log fixture, or guard the test with a file-existence check (fs.existsSync + test.skip())
  2. Sign the CLA to unblock merge

Summary

Re-reviewed after new commit 7eca2f57 (fix: stable per-line step.id derivation + non-overlapping STEP time windows). The dual-source architecture (hook envelope path + rollout data path) with shared deriveSpanId() for cross-source stitching is well-designed. The fail-open contract, per-turn idempotency guard, and baseline-skip are all properly implemented.

However, CI is still failing — the probe-hook-trace.log fixture file referenced in hook-processor.test.mjs:130 is not committed, causing ENOENT. This is the same issue flagged in the previous review; the new commit addressed step.id derivation but did not fix the missing fixture. Cannot approve until CI passes.

Findings

  • [Critical] tests/unit/hooks/zcode/hook-processor.test.mjs:130 — Missing fixture probe-hook-trace.log causes CI failure (ENOENT). Same as previous review.
  • [Warning] src/inputs/zcode-rollout/zcode-rollout-input.ts:22@ts-expect-error will break if a .d.ts shim is added later; consider a minimal type declaration file.

Suggestions

  • Commit tests/unit/hooks/zcode/fixtures/probe-hook-trace.log (or git add if it exists locally but wasn't staged), or skip the test with a TODO until the fixture is available.
  • For the @ts-expect-error import, a minimal assets/hooks/shared/event-emitter.d.mts exporting declare function toW3CTraceId(value: string): string; and declare function deriveSpanId(namespace: string, ...keys: string[]): string; would make the import type-safe.

Positive Notes

  • The deriveSpanId() shared function approach for cross-source parent linking is a clean solution — deterministic, no shared in-process state needed.
  • The eventsRoot addition to hook-strategy.ts is backward-compatible and well-scoped.
  • Cross-batch tool-call pairing (bufferPendingToolCalls / flushPendingToolCalls) handles a real edge case properly.
  • Test coverage for the paired-fixture consistency and span_id derivation contract is good.

[Critical] The fixture file probe-hook-trace.log is not committed, so CI fails with ENOENT on this line. This is the same issue flagged in the previous review; the new commit (7eca2f5) fixed step.id derivation but did not add the missing fixture. Either commit tests/unit/hooks/zcode/fixtures/probe-hook-trace.log, or remove/skip this test until the fixture is available.

[Warning] The @ts-expect-error on line 20 will become an unused-suppression error if a .d.ts declaration is ever added for event-emitter.mjs. Consider adding a minimal event-emitter.d.mts shim exporting toW3CTraceId and deriveSpanId signatures so the import is type-safe without suppression.

… on AGENT/STEP spans (#136 iter8 round 2)

- AGENT span: emit gen_ai.framework='zcode' + gen_ai.framework.version (detected via `zcode --version`, overridable by ZCODE_CLI_VERSION env, fallback 'unknown')
- STEP span: emit gen_ai.react.round — per-turn monotonic counter starting at 1, idempotent via stateStore (seenStepIds keyed by sessionId+turnId)
- Unit tests: 25→37 in rollout-input.test.ts (12 new cases covering version detection paths + react.round idempotency)

2 gen_ai.react.round STEP nextReactRound(sid, tid, stepId) — per-turn 单调递增(从 1 起),幂等(stateStore seenStepIds keyed by sessionId+turnId),跨 batch/重启存活

#3 BLOCKER 决策

gen_ai.cache_creation_tokens(原 #3):N/A。证据采信 developer 报告——~/.zcode/cli/rollout/*.jsonl 3 个 session 的 usage keys 仅含 cacheReadTokens / inputTokens / outputTokens / reasoningTokens / totalTokens,无 cache_creation 来源。上游 zcode CLI 限制,非探针侧缺口,本期不推动上游改动。下一轮覆盖率统计时分母应剔除 N/A 项。详见 coordinator 决策评论。

Summary

Re-reviewed after new commit ff6a81e7 (gen_ai.framework/framework.version/react.round on AGENT/STEP spans, iter8 round 2). The new attributes follow the ARMS gen-ai spec extension correctly: gen_ai.framework is a constant "zcode", gen_ai.framework.version uses a cached async-spawn detection with a sync fallback, and gen_ai.react.round is a per-turn idempotent ordinal counter. The async/sync split for version detection is pragmatic and the fail-open design is appropriate for a telemetry collector.

However, CI is still failing on all Node versions (18/20/22) — the probe-hook-trace.log fixture file referenced in hook-processor.test.mjs:129 is not committed. This is the 4th consecutive review flagging the same blocking issue. The PR cannot be merged until this is resolved.

Additionally, CLA is unsigned — even if CI were green, this PR cannot be approved/merged until the contributor signs the CLA (see the CLA reminder comment).

Findings

  • [Critical] tests/unit/hooks/zcode/hook-processor.test.mjs:129 — Missing probe-hook-trace.log fixture causes ENOENT on all CI runs. Please commit the fixture file or guard the test with fs.existsSync.
  • [Warning] src/inputs/zcode-rollout/zcode-rollout-input.ts:102spawn() call in detectZCodeVersion() has no timeout; a hanging zcode binary would leak the child process. Consider adding setTimeout(() => child.kill(), 5000).

Suggestions

  • For the spawn timeout, a simple pattern:
    const timer = setTimeout(() => { child.kill(); this.zcodeVersion = 'unknown'; resolve('unknown'); }, 5000);
    child.on('close', () => clearTimeout(timer));
  • For the fixture issue, if the file contains sensitive runtime data, consider generating it programmatically in a beforeAll hook instead of committing a binary log.

…s via llm.request stamping + flusher AGENT enrichment (#136 iter11)

Root cause: OTLP AGENT/STEP span_id is allocated randomly by OTel SDK; the library's
converter filters `event.name="other"` envelopes out of parentRecords, so framework/
react.round fields stamped on envelopes never reach OTLP spans.

Fix:
- zcode-rollout-input.ts: stamp gen_ai.framework / framework.version / react.round on
  llm.request records (real parentRecords consumed by buildReactStepInvocation)
- otlp-trace-flusher.ts: add enrichAgentSpansWithFramework() — post-convert hook that
  writes gen_ai.framework / framework.version onto AGENT span attributes by matching
  gen_ai.session.id to AGENT span's gen_ai.conversation.id
- tests: 5 new/updated test files (145/145 pass in zcode+flusher suites)

Upstream exit-gate evidence: tester comment 9edb5e84 — real zcode CLI E2E PASS,
13 spans / 0 ERROR / gen_ai.framework + framework.version on AGENT span /
gen_ai.react.round on 4 STEP spans monotonically increasing [1,2,3,4] /
input/output.messages non-empty. dist md5 d772d9c9168b9e25c0c22030f76c2084
worktree==installed.

Known followup (out of scope): gen_ai.framework.version="unknown" when daemon
does not inherit ZCODE_CLI_VERSION env — to be addressed separately.

iter11 — fix gen_ai.framework / react.round landing on OTLP spans

Commit

  • f5216f9fix(zcode): land gen_ai.framework/react.round on OTLP AGENT/STEP spans via llm.request stamping + flusher AGENT enrichment (#136 iter11)
  • Identity: pilot-reviewer-v2 <reviewer-v2@multica.local>
  • 5 files / +469 −1

Root cause (revised from iter10 hypothesis)

The iter10 hypothesis ("envelope span_id mismatch with OTLP span_id") was wrong. Real root cause: OTLP AGENT/STEP span_id is allocated randomly by the OTel SDK — deriveSpanId is only used on the envelope record itself, never read by the SDK. The library's converter filters event.name="other" envelopes out of parentRecords, so framework/react.round stamped on envelopes never reach OTLP spans.

Fix

Summary

Re-reviewed after new commit f5216f9 (gen_ai.framework/react.round on OTLP AGENT/STEP spans via llm.request stamping + flusher AGENT enrichment, iter11). The new enrichAgentSpansWithFramework() function is well-designed: it harvests framework info from input records keyed by gen_ai.session.id, joins AGENT spans via gen_ai.conversation.id, and additively sets attributes without overwriting existing values. The reactRound reorder in the rollout input is a clean refactor. Test coverage for the enrichment logic is included.

However, this PR still cannot be approved — CI is failing on all Node versions (18/20/22).

Findings (unresolved from previous review — 5th time)

  • [Critical] tests/unit/hooks/zcode/hook-processor.test.mjs:129 — Missing probe-hook-trace.log fixture causes ENOENT on every CI run. This is the 5th consecutive review flagging the same blocking issue. The PR cannot merge until this is resolved.
  • [Warning] src/inputs/zcode-rollout/zcode-rollout-input.ts:102spawn() still has no timeout guard; a hanging zcode binary leaks the child process.

Suggestions

  • Commit the fixture file, or replace the readFileSync with a guarded if (fs.existsSync(...)) + programmatic fixture generation in beforeAll.
  • Add a spawn timeout as suggested in the previous review.

The framework enrichment implementation itself is solid and ready — please resolve the two outstanding items so CI goes green.

Summary

Re-reviewed after new commit 7eca2f5 (V3 hybrid: envelope-only hook path + rollout data path + cross-source deriveSpanId stitching + enrichAgentSpansWithFramework react-round stamping).

The architecture is well-designed: the hook-processor emits ENTRY/AGENT envelopes only (no messages), while ZCodeRolloutInput tails the rollout JSONL for full LLM/STEP/TOOL + messages data. Cross-source parent linking via shared deriveSpanId('agent', sessionId, turnId) / toW3CTraceId() is the correct single-source-of-truth approach. Fail-open contract, baseline-skip on first install (onStart → offset to EOF), and cross-batch tool.call→tool.result pairing are all properly implemented. 1666 tests pass.

However, this PR still cannot be approved — CI is failing (1 test).

Findings

  • [Critical] tests/unit/hooks/zcode/hook-processor.test.mjs:128 — Missing fixture file tests/unit/hooks/zcode/fixtures/probe-hook-trace.log. The test calls fs.readFileSync() on a file that is not committed in this PR, causing ENOENT on Node 18/20/22. This is the only failing test (1 of 1667+). Same issue flagged on the previous commit f5216f9 — please add the fixture file.
  • [Info] src/deployment/hook-strategy.ts:322 — The eventsRoothookJsonPath logic is duplicated in two methods; consider a shared helper.

Positive

  • enrichAgentSpansWithFramework() cleanly harvests framework info from input records keyed by gen_ai.session.id, joins AGENT spans via gen_ai.conversation.id, and additively sets attributes without overwriting — good design.
  • Shared deriveSpanId() / toW3CTraceId() imported from the same .mjs in both the hook-processor and the TS rollout input — guarantees cross-source span_id/parent_span_id matching without shared in-process state.
  • onStart() baseline skip correctly initializes byte offset to EOF for unseen rollout files, preventing history replay on first install.
  • Placeholder tool.result (1ms duration) for orphaned tool calls keeps traces complete when the next LLM line never arrives.

Summary

This PR adds ZCode CLI as a new supported agent in loongsuite-pilot, implementing the V3 hybrid architecture:

  • Hook path (boundary spans): emits ENTRY/AGENT envelope records on Stop events
  • Rollout path (data source): tails for LLM/STEP/TOOL spans + messages
  • Cross-source stitching: shared + ensure deterministic parent-child linking across processes

The architecture is clean, the fail-open contract is properly implemented, and test coverage is comprehensive (953+ lines of tests). The baseline skip on first install prevents history replay.

⚠️ This PR has merge conflicts with that need to be resolved before it can be merged.

Good use of shared deriveSpanId()/toW3CTraceId() from the hook processor — this ensures cross-source span linking is deterministic. The @ts-expect-error for the .mjs import is acceptable but consider adding a .d.ts shim file to get type safety in the future.

The fail-open contract (error → stdout "{}" + exit 0) is correctly implemented throughout. Good defensive coding.

Summary

This PR adds ZCode CLI probe support to loongsuite-pilot with a dual-source architecture: real-time hook-based collection and offline rollout JSONL reconstruction. The implementation includes a hook processor, shell wrapper, message converters, state management, transcript parser, input adapters, and comprehensive test coverage.

Overall verdict: COMMENT — code quality is good, but the PR has merge conflicts with main that must be resolved before merging.

Key Strengths

  • Fail-open contract: All error paths in hook processor and shell wrapper output '{}' and exit 0, ensuring ZCode is never blocked
  • Bounded state: Session state management with MAX_SESSION_ENTRIES prevents memory leaks
  • Cross-source trace stitching: toW3CTraceId and deriveSpanId helpers ensure hook and rollout paths produce compatible trace/span IDs
  • Robust Node.js detection: Shell wrapper correctly handles Homebrew/nvm/fnm shims
  • Test coverage: Unit tests for message converter, state management, and transcript parser

Findings

  • [Info] assets/hooks/shared/event-emitter.mjs — toW3CTraceId/deriveSpanId helpers are well-designed for cross-source trace stitching
  • [Info] assets/hooks/zcode-hook-processor.mjs — Fail-open contract is correctly implemented throughout
  • [Info] assets/hooks/zcode-loongsuite-pilot-hook.sh — Node.js version detection and fallback logic is robust
  • [Info] src/inputs/zcode-rollout/zcode-rollout-input.ts — Consider adding a comment explaining why rollout events don't include ENTRY/AGENT spans

Action Required

⚠️ Merge conflicts detected — please rebase onto latest main and resolve conflicts before this PR can be merged.

Good addition of toW3CTraceId and deriveSpanId helpers. The cross-source span_id derivation ensures hook ENTRY/AGENT envelopes can be stitched with rollout LLM/STEP records under a single trace_id without shared in-process state.

Minor: the comment mentions 'stitch' but is cut off — consider completing the sentence for clarity.

The hook processor follows the fail-open contract correctly — all error paths output '{}' and exit 0 to avoid blocking ZCode. The session state management with bounded maps (MAX_SESSION_ENTRIES) prevents memory leaks.

The dual-source approach (hook for real-time + rollout for offline reconstruction) is well-designed for resilience.

Shell wrapper is robust with proper Node.js version detection and fallback logic. The app-bundle detection (node_is_app_bundle) correctly skips Homebrew/nvm/fnm shims to find a real Node.js binary.

Good defensive programming: all error paths output '{}' and exit 0.

The rollout input adapter properly handles the offline reconstruction path. The use of deriveSpanId ensures parent_span_id references match the AGENT envelope span_id from the hook path.

Consider adding a comment explaining why rollout events don't include ENTRY/AGENT spans (they're provided by the hook path).

Summary

This PR adds ZCode CLI probe integration with a well-designed dual-source collection architecture (hook processor for real-time envelope events + rollout input for offline trace reconstruction). The cross-source trace stitching via deterministic deriveSpanId is clean and avoids shared state between processes. Test coverage is thorough (24 tests across 3 files) with paired fixture consistency proofs.

Overall the implementation is solid. Two minor suggestions inline.

Minor: str() and num() helper functions are duplicated across message-converter.mjs, zcode-rollout-input.ts, and other files. Consider extracting to a shared util module (e.g., assets/hooks/shared/utils.mjs) to reduce duplication.

Summary

Adds ZCode CLI probe support via a V3 hybrid architecture: hook path emits ENTRY/AGENT boundary spans, rollout path tails JSONL for LLM/STEP/TOOL data with messages. Cross-source stitching via shared deriveSpanId() ensures deterministic parent-child linking.

Strengths:

  • Fail-open contract consistently applied (hook never blocks zcode)
  • Comprehensive error handling and logging
  • Cross-batch tool call pairing with state persistence
  • Baseline skip on first install (no history replay)
  • File rotation/truncation detection via inode tracking
  • 24 unit tests covering core functionality
  • Well-documented architecture decisions

One minor consistency note (see inline).

[Consistency] MIN_NODE_MAJOR=18 here, but PR #100 bumps docs to "Node.js 20 or later". Consider aligning to 20 for consistency across all hooks, or document why zcode hook stays at 18.
