#391 Technical disclosures: OpenChronology's mechanisms in implementable detail

[Anonymous]

Originally created by: athanclark

Refs [#388]

Adds docs/disclosures/: a dated, public technical description of OpenChronology's mechanisms, detailed enough to implement, as a defensive publication. It is engineering documentation with one short, neutral statement of purpose and no legal claims.

Disclosures

Document	First public
rational-time.md: exact rationals, ordering across JS/PostgreSQL/SQLite, oc_qkey	88aea8c 2026-10-05, v0.1.0
viewport-rasterization.md: power-of-two grid camera rounding, reciprocal wheel factors	88aea8c 2026-10-05, v0.1.0
persistent-interval-index.md: AVL moment/duration/arc trees as rows, bounded walks, O(k log n) saves	88aea8c / 61c0f77 2026-10-08, v0.1.0
history-and-forks.md: versions as rows, read-through forks, versioned index rows, differences, merges	d7a9a23 2026-10-13, v0.1.0
summaries-and-clustering.md: anchored-span grouping, 256 longest bands, layout	88aea8c 2026-10-05, v0.1.0 (bands v0.9.4)
viewport-cache.md: multi-resolution window cache, prefetch, eviction, IndexedDB	6530edf 2026-10-07, v0.1.0

log-ingestion.md: syslog/journald/log files at exact times, batching, retention	055e5d6 2026-10-10, v0.1.0
time-mapping.md: exact affine time mapping, delete-range, comparisons	7347c96 2026-10-15, v0.1.0
desktop-file-format.md: .och disk baselines, token-matched saves, staged patches	6530edf 2026-10-07, v0.1.0

Each document covers the field and problem, the mechanism, data structures, algorithms with pseudocode, complexity, variations, implementation links pinned to 007091c, benchmarks (cited from docs/benchmarks.md, docs/architecture.md and tests; the rasterization bit-size table was measured by running the code), and first public disclosure. Where code and docs disagree, the documents follow the code and say so.

The index's Keeping the record section says releases and tags are never deleted or force-moved, and lists follow-up steps for the maintainer (none taken here): Software Heritage Save Code Now, optional Zenodo DOIs per release, optional submission to Technical Disclosure Commons. Immutable releases are currently off for this repository and no ruleset protects tags; both are repository settings.

Linked from README.md and docs/README.md. npm test passes; Prettier is clean on the changed Markdown.
