`packages/hale2026harmonic/`	Two sections of a converted chemistry paper, read once with errors and fixed by twelve corrections: a digit, a lost superscript, a missed boundary, a false boundary, a split paragraph, a running head, two labels, a garbled row replaced, a dropped row inserted, and a header span. It has a multi-level-header table, a display equation inside a sentence, a footnote, a figure with figure text and a real image asset, references, legacy aliases, geometry on fingerprinted pages, receipts (one partly invalidated by a correction, one spot-checked clean, one revoked, one suspended), a roster, a reported dataset and derived MathML.
`packages/hale2026harmonic.checks-only/`	The same document exported to another machine of the team: text withheld, values under the team key in `keys/`.
`packages/okafor2025open/`	An open-access paper with a JATS witness and a PDF witness, corroborated.
`packages/smithlab2027charges/`	A short Typst draft that cites sentences of `hale2026harmonic` by address.
`packages/tiny2026example/`	A small document; the base of the correction vectors and the invalid packages.
`records/`	A valid record of every other format: anchors (span, leaf, cell, paragraph and keyed), rights, a policy, backends, profiles, a layer with its annotations and receipt, submissions, grades, a project, a digitization with its confirmation and dataset, a view, a QA report, a snapshot and a draft's sentence IDs.
`invalid/<case>/`	A package that breaks one rule, and `expect.json` naming it.
`keys/`	The Ed25519 test keys that signed the fixtures, and the checks-only export's team secret. Public; never use them for anything else.
`src/`	The hand-written sources of the three M1 documents (src/README.md).

Everything except src/ is generated by python3 tools/build.py; do not edit it by hand.
