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.
- A key landing on a side panel's tab steps into the card it peeks open, not onto the hidden tab.
- The Channels cards keep their status / pager row at the list's end while the band is folded.
- A menu row's note shows on an enabled row too: the download state under 'Download…', not a title.
- A removal chip hands the focus to its neighbour before it goes, for every caller (the feed's and
Plex's active filters); the hidden-filter cue's own copy is gone.
- Back to a spot within a page's end spacer lands at the page's end, not its top.
- A running push / revert is tracked per list: another list's push is no longer refused unseen.
The card's own pin and the drawer's still said 'Unpin panel' / 'Pin panel open' after the edge tab
learned the title (F6). Naming them too made two buttons share a name, because the invisible tab
under an open card was still in the accessibility tree: it is now aria-hidden as well as out of
the Tab order. The generic sidebar.pin / unpin keys are gone.
- F5: a chip's × pressed from the keyboard hands the focus to the next chip (else the previous one,
else what follows) before it unmounts — in DismissibleChip, so all five chip rows get it
(`focusNeighbour` in lib/useFocusKeeper).
- F4: a drag grip names what it lifts (`common.order.dragNamed`: panel groups, personal views);
the two generic "Drag to reorder" keys are gone.
- F6: the side panel's edge tab is out of the Tab order while the card covers it, names its panel,
and a keyboard pin moves the focus into the card.
- F7: Back to top is no Tab stop while hidden, and a keyboard press leaves the focus on the page.
C2 as decided: on a coarse pointer, or a window below 768, the panel's
tab (shown at every width, 44 wide on touch) opens the panel as a
start-edge drawer over the content, with a scrim. It is ui/Modal's new
drawer-start placement, so Esc, Back, the scrim, the focus trap and the
scroll lock are the dialog's own. A tap never peeks; pinning is a button
in the drawer's header, offered only at 1024 and up; a pin saved on a
desktop is left alone below that. A mouse on a wide window keeps
hover-to-peek and click-to-pin.
DESIGN: C2 as built, rows answer to their own width, phone-only layout
deferred to its own epic (principle 2).
