Independent S2b evidence archive audit

Reviewed .local/analysis-source-s2b-evidence-20260913 without executing its archive helper, gate/admission helpers, compiler, tests, GUI or Gitea. No archive, root source, HEAD or index edit was made. This report records file/JSON/log inspection and read-only Git object comparison; it does not claim publication or public source8 acceptance.

No actionable archive finding. The archive accurately preserves a private lowering checkpoint with a failed full library gate. The corrected source is a2a28f8d23a46ba1696b6a8410d4d3b5c1808f49; original failed source is 472fe7a4339a23a3339b2b91e8d53d76442f60c4; comparison baseline is b2c970b4673e062e47eadd12906d2316c4b1a7b3.

Bytes and provenance

• Manifest: 12,001 bytes, SHA256 d5b2668207438e319c2ab98395e2483c016088c5446b6bc99d797a066384a62f.
• All 40 raw archived files match manifest lengths/hashes and their still-available original local bytes. Both generated files (audit.json, README) match their manifest bindings. These 42 payload files total 1,254,441 bytes; including the manifest, the exact archive tree contains 43 files. There are no unlisted files or missing payloads.
• audit.json: 73,824 bytes, SHA256 34d10fafb8046943d7d0a1bd0ffee9de334bdff37019b033d1b2bbbf057d78c4. Independently recomputed runtime outcome maps match it. All 32 full-failure section hashes/starting lines and complete diagnostic excerpts match the original raw logs.
• The bound archive helper is preserved as evidence; it was not rerun. Original local paths identify provenance, while actual archived files live under evidence/.local/. Binaries/toolchains are explicitly omitted. Recorded historical executable identities are preserved, not claimed to have been reread from mutable target paths.

All five receipts have matching source/head, nonempty ordered start/end and unchanged inputs. Every corrected input manifest is the same 531-row manifest, SHA256 08b6dabbffbd06f7abea717f9aa34cd910c41c4a8c650247006a0f6858561c84; its membership, sizes and hashes were independently compared with the exact committed input scope and raw Git blobs. Original472 likewise has 531 exact inputs; baseline b2 has 524. No source count was inferred from a report.

All four corrected test runs record one identical executable: 36,685,824 bytes, SHA256 ce9d77ed1e68a21e06836264bf50ba9dddbfa69507e1a0bc2c05a7b55db325a9. Strict records no test artifact. Actual commands match list/focused/full oa-core --lib and strict oa-core --all-targets; this is not a full all-targets runtime or doc-test claim.

Exactly three corrected admissions exist: listing, typed and raw tokens. Their input/result/log/helper/baseline hashes and executable identities match the archived originals. Their admitted names equal the actual selected raw outcomes. No corrected full-pass admission exists, and the README does not imply one.

The corrected and original472 listings each contain the same 142 names. Independently subtracting b2's 129 names gives exactly the 13 test functions authored in language/analysis_source/lower/tests.rs; all 129 prior names remain. The 13 new names match audit.new_members exactly and each is ok in both corrected typed and full logs. Entire ordered runtime membership and summaries were checked, including no unexpected ignored outcomes.

Preserved failures and cause scope

The original472 focused log retains its actual 33 passed / 1 failed / 0 ignored, exit101. The failing all_thirteen_expression_variants_lower_to_real_typed_values_and_admit reports analysis_type for AsKind at lower/tests.rs:45:54. The archived correction review identifies an invalid named-input positive oracle. The 472-to-a2 Git diff is only that test file, 19 additions/5 deletions; it does not change production lowering or numeric semantics. The corrected run is separate evidence, not relabeling of the original failure. The original test artifact remains distinct: 36,686,336 bytes, SHA256 732018626fceff6c6a75ea51e114a32ca96a11999cf6f135c077df49278853b7.

Actual b2 full is 113 passed / 16 failed, exit101, with artifact 35,920,896 bytes, SHA256 67249b37f30b596eb3deb95a217bd77eb06905bdf7b6c27b74fec16f9f0362e5. Independently compared all 16 a2 and b2 panic blocks: failed names, panic source locations and complete diagnostic lines are identical apart from surrounding thread IDs. Each rejects source version at line1/column9/span8..9. A matching-name assertion alone was not used to establish this result.

The archived failure-cause review is appropriately bounded. Source readback independently confirms model.rs:9 has schema8; language.rs:506 writes that version while language.rs:1335-1337 accepts only3-7. Direct nesting round trips fail at language_nesting_tests.rs:63,124. For bundle cases, source_project.rs:297-298 invokes upgrade, source_project/source_migration.rs:83 writes the current version, and line115 reparses it through the unchanged public parser. The transaction fixture begins as valid source5 and fails at source_files.rs:1560 before its later save/recovery operation. All seven files named by the cause review, including the checked-in source3 entry, are byte-identical between b2 and a2. The 16 failures therefore do not validate later nesting/save/recovery behavior and cannot be waived into a full pass.

The cause review explicitly predates tokens/strict and does not claim their completion; their actual later receipts are separately present. Historical b2 production-language 7/9 is mentioned only as a separate S2a limitation, not a corrected a2 run. Public source8 writing/migration, native workflows and release acceptance remain outside this archive's successful scope.

Readback and limitations

All manifest payloads and originals were checked again after review; manifest bytes remained unchanged. No new source test or artifact execution occurred. The archive is internally consistent evidence for the stated private milestone, with full-library failure still explicit. Source bodies/toolchains/executables are not packaged here; later publication must retain access to the identified source commits and must not promote this archive into public8, native or full-suite acceptance.
