# Evidence Task 5C report
|
|
|
|
## Delivered
|
|
|
|
- Added `vector.retain_published_generations` (default `3`, validation minimum `1`).
|
|
- Retention runs only after publication. It keeps ACTIVE, the newest configured generations,
|
|
and generations referenced by running or resumable failed job checkpoints.
|
|
- Cleanup deletes the exact Evidence generation from the vector store before removing its
|
|
immutable filesystem directory. Vector failures retain filesystem metadata for retry and
|
|
produce credential-free partial reports.
|
|
- Added idempotent `tht preprocess evidence gc [--dry-run] --json` reconciliation with pristine
|
|
JSON output.
|
|
- Materialized document reads now open generation/documents components with directory file
|
|
descriptors and `O_NOFOLLOW`, require a regular file owned by the process with one link, and
|
|
hash the bytes read from the same descriptor against the canonical manifest.
|
|
- HTTP generation deletion is pinned to `delete_vector_generation` with exact
|
|
table/kind/generation arguments. Legacy 404 responses fail closed with an actionable,
|
|
sanitized migration message.
|
|
|
|
## Evidence
|
|
|
|
- Focused retention, safe-read, CLI, and HTTP contract tests: `51 passed` (Docker-backed direct
|
|
parametrizations excluded from that focused invocation).
|
|
- Real Docker pgvector adapter suites: `33 passed`.
|
|
- Full harness suite, including Docker-backed tests: `668 passed, 5 deselected`.
|
|
- Changed-file Ruff: clean.
|
|
- `git diff --check`: clean.
|
|
|
|
The five deselected tests are the repository's opt-in `l2` tests requiring external services;
|
|
they are not local pgvector tests. Test output retains pre-existing Pydantic serialization and
|
|
legacy-config deprecation warnings.
