The code cited its plan instead of saying why: `E28 review J4`, `(R6 S3b)`, `S1 justified…`,
`deep-review round 5`. That plan lives in the private ops repo, so for every reader of this one the
citation was noise, and a sentence whose subject was the plan step ("round 2 showed…") hid its
lesson behind an id. Each one is gone and the "why" kept: a bare citation is deleted, a sentence
carrying a lesson is reworded around it ("a later attempt showed…").
Measured (`scripts/audit_metrics.py`, product code): 652 lines in 270 files carried an epic code by
the definition the next commit holds (507 / 241 by the old, two-digit-only one) -> 0. Across all
code, tests, scripts and configs: ~1100 epic-code lines plus ~320 sprint/round ids.
Behaviour unchanged, checked mechanically: every changed .py file has the same AST once docstrings
are blanked; css/sh/toml/yml/json files are identical once comments are stripped; the only
non-comment changes in TS/JS are test titles, one description string in a contract table, and five
ESLint messages, whose text is all the gates snapshot diff holds. Not touched: Markdown (docs and
the changelog keep their history), Alembic migrations, TV episode notation (`S2 · E5`), DESIGN.md
ids (`C1`, `B4`, `S3h`), tracker ids (`SEC-16`, `DX-17`).
One stale claim fixed on the way: test_hls_reaper's docstring said the player checkpoints "every
10 s whether or not it is playing", which plex/stream.py calls wrong; it now says what the code does.
The suite was pure-logic only (R2 S2b deferred the DB lane). Add an opt-in `db`
fixture (tests/conftest.py) that hands a test a real session against an ephemeral
Postgres; schema is built with `alembic upgrade head` (the real prod schema needs
the unaccent extension + unaccent_simple TS config that create_all can't provide,
and this also proves the migration chain applies). Each test starts from a TRUNCATEd
clean DB so tests that COMMIT — the whole point, for R6 S2's transaction work —
don't leak.
backend/docker-compose.test.yml wires an ephemeral tmpfs pg + the test image. When
no Postgres is reachable (a plain `docker run`), the DB tests SKIP and the pure-logic
lane is unchanged: 172 passed, 2 skipped. With the DB: 174 passed.
test_db_lane.py smoke-proves commit round-trip + TRUNCATE isolation. The gate wiring
(siftlode.sh) lands in the ops repo.
