Keyed by `extra_body.session_id` (parsed in `route_request`). +4. **Integration hooks** (~30 LOC) — `http_server.cpp:510` (pre-compress: read state → set `creq.keep_ratio`), `:675` (post-generate: `step_adaptive_keep_ratio(state, result.accept_rate)`). +5. **One log line per turn** (~5 LOC) — `[pflash-bandit] session= turn= keep=→ (accept=, ema=)` +6. **One fake-backend integration test** (~30 LOC) — `dflash/test/test_adaptive_keep_ratio.cpp`.

Server self-tunes per session from DFlash chain accept_rate. Client sends nothing — no `keep_ratio`, no `pflash_mode` — and the server picks the right compression for the workload turn-by-turn. Validated on claude_code and opencode multi-turn at 32K. ~220 LOC, one PR, no kernel changes. The skip+anchor work stays separate on the evidence branch as `pflash_mode=always` opt-in for users who explicitly want the prefill speedup. That's the MVP you asked for; the rest is extension material. + +## Drift discipline (the lesson from today) + +The chronos review confirmed that today's "drift" produced solid bench foundations (envelope, anchor coverage, composition, real-transcript study) but ALSO produced a paper plan, scaling roadmap, v2 ideas, and Momus/Codex critiques that are **text-only without experiments backing them**. This PLAN.md retains all of those as future work but **does not let them block the ship**. The bandit is the ship; everything else is a follow-up. + +If anyone — including me — proposes adding scope to this PR, the answer is "make it a follow-up PR."
