feat(igp24): publish batch notes and runnable release audits
The published README promised participant notes, but the completed export
had not been uploaded. Add the unchanged raw batch notes and their record links
under data/notes/, with a schema and sanitized source report. The export contains
133,316 batches, 77,271 non-empty notes, and exactly 50,428,828 polynomial links.
Notes are not classified or rewritten, and non-empty text is not counted as
verified external provenance. Public submission IDs are unavailable for 8,226
batches; their batch IDs and record links remain complete.
Publish the September batch-association audit in a standalone Cargo project and
a new Python integrity/structural audit with tests. The original August audit
script was not located: the new tool is explicitly distinguished from it, and
the historical report is unchanged. Update README links, obsolete review-branch
examples, and the repository-wide SHA256SUMS manifest.
Validation: all 51 shard checksums and row counts recomputed; exact multiset
comparison covers all 50,428,828 IDs with zero missing, extra, or duplicate IDs.
The Python run validates 51,000 sampled shard records, all 163,910 minimal records,
and all 1,926 missing-pair entries. Nine Python tests and three Rust tests pass.
Full Python structural/minimum-selection mode is provided and fixture-tested,
but has not been run over all 50 million records. No Magma/PARI recomputation is
claimed. The raw gzip hash is 83311e31cc62f5d701631e1cb5cc07f32df763a58b715383702a7b6d2247fa5d.
Existing polynomial files, scoring inputs, license, historical reports and
leaderboard are unchanged. This PR does not modify main or move v1.0.0.
