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.
Restores CLAUDE.md's canonical transaction rule ("the handler commits; helpers
flush; only quota owns its session") on the config path: sysconfig.set_value /
sysconfig.reset and state.set_sync_paused now flush instead of committing, so a
change lands in ONE transaction with the audit row the route records for it —
previously the helper's internal commit split them, and a crash between left the
mutation persisted with no audit trail.
All callers already commit (the config PATCH/DELETE + audit, the sync pause/resume
+ audit, the scheduler maintenance PATCH); the setup wizard, which relied on the
internal commit, gets an explicit db.commit() after its loop. apply_interval is
deliberately left committing — it performs a live APScheduler reschedule that must
follow the DB persist, so it owns its own unit of work (a legitimate exception,
like the download service transitions). New test locks the flush-not-commit
contract (a rollback before the caller commits discards the change). 368 pass.
