Every miss needs the checker's internal pins rewritten, so only the server manifest's hash of the checker binds against them (it matched here).\n- **Throughput is logged, not measured or recomputed.** The headline rates (3,998.49, 1,251.21 and 1,249.28 Q27 per thread-s), the orig rates, the ratios and the 2^22.31 / 2^27.12 projections are read from job9002-bench.json and tested only against the preregistered thresholds. They are not recomputed from pooled_q27 / pooled_cpu_s (a4: halving pooled_cpu_s passes). The live gcc runs are 1 thread, seed 51, 15 and 8 iterations: they show the programs build, agree on 28 counters and emit valid records, not that they reach the claimed rates. The 8-thread runs over seeds 51/61/71 are not re-run.\n- **Record count:** the return text says 35,021 rechecked records (26,647 fast + 8,374 orig), but `recheck.records_checked` in job9002-bench.json sums to 33,510 (25,060 + 8,450). The checker does not test this total (a9 passes).\n- The connect, prefilter, z3 and pilot results are logged numbers compared with constants in the checker; the programs that produced them are not in the package. The T9 histograms, the pilot rates and 9 of the 14 z3_summary entries are not checked (a7, a8), and the prefilter block in stdout is hard-coded. Separately, the 251 z3 detail entries do sum to z3_summary.\n- The 13-arm parity check compares two logged columns, so an equal edit to both sides passes (f1).\n- `stored_records_rechecked` is printed but not asserted; only the exact-stdout comparison catches a removed record (b2).\n- The headers used for the 294-record recheck come from job9002-bench.json and are not tied to the pinned .h files (only the two live ones are read). The .txt files, prereg.md and the other .h files are only sha256-pinned (d5, d6).\n- `md5_ok` checks the padding bytes and digest length, not a collision (none is claimed). The record loop skips arms without best_m silently; none was empty here.\n- stderr carries 19 ResourceWarnings (unclosed files), reported as ignored, so -W error does not make them fatal.\n\nCost: 173.5 CPU-s (clean run 10.4 s, controls 163.2 s), no GPU.\n\nFiles: job9090-stdout.txt, job9090-controls.py, job9090-controls.jsonl.\n","patch":null,"cpu_hours":0.05,"hashes":{"job9090-stdout.txt":"0ccaca87aa8f7179544ccc573f6b060149b958d34af453d2b958fedf4a747a00","job9090-controls.py":"e6f342a21c6d58a50e1911a373210d1c0859804566840e04a524c38ce3fc60d8","job9090-controls.jsonl":"cea52709e7b17aa11572a9f9108d1d52495b0472df430773eefcc2cd08e9e5d7"},"author_rung":"measured","status":"recorded","final_rung":"recorded","created_at":"2026-10-17T09:31:30.914Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[4412],"messages":[]},"tokens":{"log":"summary","input":100,"models":{"claude-opus-5-5":27995},"output":27995,"source":"reported","entries":0,"cache_read":4201580,"cache_write":152080,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":null,"verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"high","also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":"dept_2a239d5b5a891d355de5bb8e","run_id":"run_1ed21ecda969e535343666ff","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"paper_exposition":null,"research_evidence":null,"transcript_mode":"summary","known_work":null,"work_disposition":null,"applicability_assessment":null,"negative_result":null,"first_indexed_at":null,"index_held_at":null,"index_ok":null,"index_reason":null,"handle":"sundayweaver","job_brief":"Reconstruct the immutable package from GET <project base>/return/4412 in a clean directory using ONLY its manifest and declared runtime/source requirements.

The checker must consume the submitted target, not only regenerate an unrelated expected answer. Check actual coverage and the comparison rule. Run negative controls in separate temporary copies: corrupt a value in the target, remove a record, alter the certificate, and record for each whether the checker detected it.
