Explanation
The changed spill-path rules, comparator pricing, fetch-latency merge, proxy input handling, gate updates, README generation and checks, engine performance changes, and prose-elision tests support the PR's stated benchmark, engine, and documentation objectives. The private whole-session table and
#357campaigns remain explicitly outside this change. No unrelated change is demonstrated by the available evidence.

Explanation
[
#436] The current ratchet enforcescodebase-exploration/cost-proxy,latency,retention, andturns. It does not enforcecodebase-exploration/speed. The ratchet also records the oldcodebase-exploration/speedresult as retracted. Therefore the required transform-time comparison is not complete, even though the modeled-session latency comparison and retention floor are enforced. The tie-at-p0 block-engine cost is explicitly marked NOT CLAIMED, while the proxy cost is enforced. The PR provides no evidence that the missing speed criterion now passes.Resolution
Record a valid current two-pass transform-speed comparison for
codebase-explorationwith the required p90-versus-p10 rule. Promotecodebase-exploration/speedonly after it passes and remains tied to the published capture fingerprint. If it fails, improve the implementation and add or update automated coverage until the criterion passes.

Inline comments:
Review comments at @bench/compression/chunk-merge.mjs:
- Around line 93-95: Update mergePerFetch to return an unmeasured result when
any chunk is unmeasured and has markersProbed greater than zero, preserving its
available detail. Continue skipping chunks with no markers and retain the
existing pass-merging behavior when all probed chunks have successful timings.
Review comments at @bench/compression/head-to-head.mjs:
- Around line 3161-3165: Update the final record block’s proxyCheaper condition
to require COST_PRICED as well as proxyEverywhere, so proxyCheaperAt is not
called when costs are unpriced. Keep the existing null result for unavailable
proxy row counts.
Review comments at @bench/compression/must-win.check.mjs:
- Around line 203-210: Update the `cost` criterion exemption for `cfg.costFloor
=== 'tie-at-p0'` so it does not mark `codebase-exploration/cost` as unclaimed;
keep that block-engine cost result enforced independently of `cost-proxy` unless
the acceptance criterion is explicitly changed.
Review comments at @bench/compression/readme-headroom.check.mjs:
- Around line 141-145: Update the header validation in the loop over headers to
require the complete ordered list from COLUMNS.map((c) => c.header), rejecting
missing or extra headers while preserving the existing table checks.
Review comments at @src/compress/spill-path.ts:
- Around line 42-43: Update spillBase so TOKEN_OPTIMIZER_SPILL_ROOT is resolved
to an absolute path or rejected when relative, ensuring the returned spill base
is always absolute while preserving the home-directory fallback.
Review comments at @src/proxy/server.ts:
- Line 1782: Update deadSpillRoots cleanup so rmSync only removes directories
verified as proxy-owned; alternatively, place proxy spill roots in an
application-owned namespace beneath TOKEN_OPTIMIZER_SPILL_ROOT and restrict
pruning to that namespace. Do not delete directories based only on a PID-shaped
name.

…l and their timed fetches Four comparator defects, each flattering one side: - every arm handed the engine an invented `.token-optimizer/spill/b1-block` (8 tokens) where the proxy's sink wrote <tmpdir>/token-optimizer-spill/<24hex>/<16hex>-block (~40); the engine's trial run priced the same fiction. The proxy now spills to <home>/.tok/<pid>/<15 digits>, one directory per proxy (suffixed when a process runs several), pruned by asking the OS whether the owner is alive; the engine and every bench price the same shape via src/compress/spill-path.ts. - their `<<ccr:...>>` marker was priced and the `headroom_retrieve` tool their proxy injects to redeem it (ccr_inject_tool defaults True) was not. Recorded from their package by headroom/ccr-tool.py and charged as handed tokens wherever their output carries a marker; the cached-prefix rewrite it causes is not charged, which errs in their favour. - their per-fetch latency was measured by resolve-theirs.py per chunk, then dropped by chunk-merge and read from the wrong file by head-to-head, so every latency criterion where they force a round trip read UNMEASURED. - the four raw-data rows had no proxy figure; they now reach the proxy as the text of one user turn, the shape a client really sends, and the corpus totals report the proxy arm. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ctionary value once relevance-probe's comparable speed criterion (#442) failed by 0.2 ms: our default arm's p90 8.8 ms against their p10 8.6 ms. Profiled with --cpu-prof on the recorded payload (single-threaded, 300 calls after 50 warm-up), the two largest self-time lines were in json-fragments: - records(): a regex replace with a callback ran over every compact record to rewrite escaped newlines, and returns every quoted string unchanged -- so text with no `\n` escape anywhere is its own answer. Now skipped when there is none. - dictsOf(): every cell was serialised and tokenised, repeats included. Each distinct value is now priced once and weighted by its count; the integer sums and the first-occurrence order are the same. Median of 300 calls over 7 launches each: 7.03 -> 5.96 ms (p90 7.7 -> 6.6). Output byte-identical against the previous build on all 18 payloads, with and without a sink (36 of 36). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…check in ci Prose elision recognised a source listing only by a bare leading number, so `L755| // comment`, `0300# // comment` and every `git grep -n` hit -- whose line starts with the path -- read as prose, and a listing came back with comment lines missing from its middle: the #469 failure through a different door, hit repeatedly in a live session while reading head-to-head.mjs. The gutter rule now takes a letter-prefixed or hash-terminated number and a path:line: / path-line- prefix; a path is told apart from a hyphenated word by its `/` or `.`. Three of the four new cases fail without the fix. No change on any of the 18 HeadRoom payloads, with or without a sink. readme-headroom.check ran only from scripts/verify-blockers.mjs, so the table drifted through three re-records while CI stayed green; it now runs beside the other README checks (#505). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…it cell by cell - readme-headroom.render.mjs writes the HEADROOM-TABLE block from the record, and readme-headroom.columns.mjs is the column-to-field map both it and the check read. The check accepted a figure found anywhere in its row, so a cell under the wrong column passed (agent-loop's preset figures sat under `ours`); it now requires every cell to equal its column, and every recorded workload to have a row (#505). - the corpus totals carry the proxy arm's session cost at p0 and p1 and the number of rows on which it is cheaper than their best arm, so prose that counts them quotes the record. - README: the HeadRoom section is retitled and states where each side wins (decision of 2026-10-17); the table is filled from the record in the next commit. - token counts for every target after the spill-path and tool-pricing changes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ion from the record Records: all four from one clean commit, both arms of one paired 18-workload capture, with their fetch timings carried through the merge and their retrieval tool priced. must-win: 59 enforced, 0 open, 0 regressed; --promote retracted 0. - on the four tie-at-p0 rows the cost criterion is the proxy's (decided 2026-10-17, following #435's "match the mechanism"): the block engine runs with no sink and by design cannot make the move their p=0 hand-off makes. Its cost there is reported under NOT CLAIMED, and an out-of-scope criterion is now neither open work nor promoted into the ratchet. - README: the HeadRoom table is rendered from the record (18 rows, a proxy column); the corpus sentences quote the record's totals: the proxy removes 91.5% of the tokens against their 61.4%, and costs less than their best arm on 18 of 18 rows at p=0 and 17 of 18 at p=1. The proof table's codebase-exploration row moved 53.7% -> 54.7% with the real spill path. - readme-prose: scoped to the renamed section; four declarations whose sentences are gone removed; 95.7% reclassified as another harness's figure, which it always was. The roster names bench-proof as readme-headroom's runner. - break-even: grep-output's crossing moved 85% -> 84% in both records, toward us, because their cost now includes their tool. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…8-row rewrite - known-answer scorer: a non-conversation payload now reaches the body arm as one user turn, so the mirror stub unwraps that turn the way it unwraps the envelope, and the check asserts the body arm is present on every fixture rather than absent on the non-conversations. A run that writes no record now reports the scorer's error instead of an ENOENT on the read after it. - readme-prose test: floors moved to the rewritten README's own counts (27 figures, 167 lines, 15 declarations, 10 retracted), with the reason in the test; the control's forged 97.3% is asserted absent first, because the 99.4% it used is now a real table cell. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…-subject reword The reword that fixed three commit subjects changed every SHA on the branch, so the records named a commit (f6fe362) no longer in its history. All four are re-taken from b1231a8 on a clean tree; must-win 59 enforced, 0 open, --promote retracted 0; the README provenance line follows. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…oot, stricter merge and header checks Review fixes on #506: - the proxy writes an ownership marker into its spill directory before the first spill, and prunes a dead proxy's directory only when that marker is there: TOKEN_OPTIMIZER_SPILL_ROOT may point at a shared directory whose numbered entries are not ours. A proxy-level test fails without the check. - a relative TOKEN_OPTIMIZER_SPILL_ROOT is resolved to an absolute path, since the marker's path is opened with the agent's own Read. - mergePerFetch reports unmeasured when any chunk probed markers and timed none, instead of lending that chunk's workloads the other chunks' timings. - readme-headroom.check requires the whole header in order: a column dropped from every row left no cell to disagree. - proxyCheaper is null when costs are unpriced, as proxyCorpusAt already was. No record changes: every capture chunk with markers timed them, and the recorded run is priced. must-win 59 enforced, 0 open. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

What this does
The HeadRoom comparator had four defects. Each one flattered one side. Fixing them, plus two engine changes, takes the must-win gate from 47 enforced with 16 open to 59 enforced, 0 open, 0 regressed (
--promoteretracted 0). All four records come fromb1231a8con a clean tree, both arms of one paired 18-workload capture.Comparator fixes
.token-optimizer/spill/b1-block(8 tokens), but the proxy's sink wrote<tmpdir>/token-optimizer-spill/<24hex>/<16hex>-block. That's 39 tokens of marker on Linux and 51 on Windows, against 17 for their<<ccr:...>>. The engine's own trial run priced the same fiction.<home>/.tok/<pid>/<15 digits>: one directory per proxy (suffixed when a process runs several), deleted at shutdown, and pruned by asking the OS whether the owner is alive.src/compress/spill-path.ts.headroom_retrieveto redeem a marker;ccr_inject_tooldefaults toTrueinheadroom/proxy/models.py.headroom/ccr-tool.pyrecords the definition from their own package.

costis judged on the proxy, following feat: define the must-win metrics and the gate that enforces them #435's "match the mechanism". The block engine runs with no sink, so by design it cannot make the move their p0 hand-off makes. Its cost on those rows is still reported, under NOT CLAIMED. An out-of-scope criterion is now neither open work nor promoted into the ratchet.README (#505)
