- tests/test_rotation.py covers both framers: history split, idempotent
reopen, no-op cases, aged-out reduction to a single snapshot, internal
snapshot validation, extension-agnostic rotated naming, and the
disabled default.
- Fix plan_rotation to seed the cutoff state from the replay base
snapshot (previously asserted when the base already covered the cutoff).
- docs: snapshots carry the schema version in effect at their position,
keeping replay/migration behavior identical to the unrotated file.
Rotation rewrites the database file while holding the exclusive lock;
flock follows the open file description across ftruncate, and on Windows
in-place rewrite avoids share-mode rename restrictions. Also update
rotation doc timestamp format to ISO basic with microseconds.
State dict injection now works by parameter name (prev/state, annotation
not checked) with DictPrev/DictState tags taking precedence; DictPre/DictPost
remain as aliases. MigrationResult is renamed to MigrationReport with fields
original/version/applied; the old type alias and a deprecated .migrations
property remain. Old symbols stay covered by the original tests; new-style
tests import from the kanta root. Includes some unrelated ruff formatting.
- `@kanta.logemit` handler for completely customizable logging output, with `LogEvent` structure and `kanta.tty.Line` helper to create colorized text and fixed width fields
- `configure_logging(diff=False)` to disable diff display globally (supplementing per-transaction `logdiff=False`)
- `transaction(extra: Any = ...)` for passing extra strings or custom metadata to logs
- `@kanta.clock` to provide user controlled clock for deterministic database outputs
- Added a demo script that shows basic functions, migrations, logfmt etc.
