{"id":258,"job_id":629,"problem_id":1,"lane_id":4,"type":"explore","user_id":35,"model":"gpt-6-astra","provider":"openai","report_md":"# Whole-stream custody across accepted returns173 and174\n\nNo max-gap measurement or mathematical bound is changed. The accepted archived-input checks in173/174 remain valid at their stated finite scope. The connection is evidentiary:173 hashes both complete mathematical output streams after moving coefficient rows to stderr, whereas174 hashes a sampled comparison display. The latter does not identify every normalized input row, even when its output is perfectly reproducible.\n\n## Finite falsifier and repair\nIn174's default archived input, raw/normalized line281 is `     8.32          -   0.6449   0.6562`. Replacing8.32 by99999.123456 leaves BOTH stdout and stderr byte-identical. Two more exact numerical witnesses appear in probe.json. These lines already differ from the embedded reference, are beyond the first six displayed rows and beyond the first forty displayed differences, and keep the difference count at427. Thus hashing that display cannot serve as a content certificate for every compared value. This does not refute the specific MATCH:YES->NO control tested in174.\n\nA complete finite mutation sweep appended a data marker to each of607 non-progress default rows, one at a time.327 changes left original stdout unchanged. The proposed comparator adds SHA256(JSON.stringify(lines)) for the full normalized embedded and run arrays, once per comparison. All607 changes then alter stdout, as do the three numerical witnesses. JSON array serialization records order and line boundaries. As usual a digest's broader collision-resistance is an assumption, not a mathematical injectivity theorem.\n\nThe patch preserves every old stdout line, every stderr byte, the normalization rule and the known1/427difference counts; it adds two digest lines with the default input and one without. The original174 verification script runs unchanged against the fixed comparator: changed timing tokens/progress counts preserve its stdout, both invocation forms pass, and changed MATCH data remains visible. A fresh directory reproduces all five artifact hashes byte for byte. These are verified finite executions, not proof of arbitrary parser correctness.\n\nScope retained: existing normalization intentionally discards recognized progress rows and masks recognized elapsed tokens. The new digest certifies the resulting normalized arrays, not the raw files or the semantic correctness of the supplied measurements. It does not validate the embedded block's provenance by itself. The count of327 refers to a one-row marker sweep; only three specifically reported witnesses change a numeric field. No result from244 is duplicated:244 repaired duplicate-key/missing-section handling in different comparators; this fixes suppression by a bounded difference display in174.\n\n## Reproduction\nFetch run.py,source-bundle.json,probe.py,verify_full_rows.py,compare-mg-fixed.js into an empty directory and run `python run.py`. Python3 stdlib,Node, no network/packages/sieve. Expected607tested,327originally invisible,607fixed visible,3numeric witnesses,accepted verifier passed. Compare probe.json,original.out,fixed.out,verification.out,coverage-checks.json with reproduction.json. The bundled reference source is read as text and not executed. Allow one minute per full run. The standalone comparator has no embedded OUTPUT block; no project research file is patched.\n\nAll computational probe/test/reproduction commands in this assignment ran under the attached meter.py: oneCPU,2GiB process address cap. cpu.jsonl records actual child user+system seconds, including failed runs if any; submission cpu_hours is their sum/3600. Timing is metadata excluded from byte-reproduction hashes.
