static_file_storage — deep multi-agent audit

Full output of a 95-agent audit of sigp/lighthouse#9644 ("Add static_file_storage crate") at commit 8b2bf89c2.

Method: 8 parallel finder agents (crash-safety, concurrency, platform, logic, API/docs, consumer-fit, an empirical probe agent that built and ran 9 adversarial tests against the real code, and CI parity). 30 raw findings deduplicated to 29; every finding independently judged by 3 adversarial verifiers (reachability / accepted-tradeoff overlap / severity calibration). Vote totals: 82 confirmed / 5 refuted / 0 accepted-tradeoff out of 87. Findings matching the six tradeoffs the author had already accepted (reader-blocking mutex, Err-though-durable write_config edge, no per-record checksum, persisted data_len, runtime-only max_value_bytes, no compression) were excluded by instruction.

Executive verdict

The core design is sound: every power-loss window in the data-fsync -> offset-fsync -> con

Run from the root of a Lighthouse checkout on the FCR branch:
