On an iPad a tap's synthetic mouseenter opened the Tooltip; WebKit then took the
tap as a hover and swallowed its click, so every rail button needed two taps,
and with no mouseleave from a finger the caption stayed up. Tooltip now opens
for a mouse and a key's focus only (owner: no captions on touch).
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 feed card cost ~10 Tab stops, so the tenth card sat ~135 Tabs from the top of the page, and the
only keyboard focus ring (a 60% accent outline on the thumbnail) all but vanished on the dark glass.
First slice of the E11 keyboard layer (S4a); Home, Plex and the tables follow in S4b/S4c.
- `lib/listNav`: one window listener over every registered list, walked in document order. `j`/`k`
step item to item (on into the next list — owner decision D4), the arrows move around a grid, Enter
clicks the item's own `data-nav-open` element, so it opens exactly like a click. An item root is
never a Tab stop: it gets `tabindex=-1` only while the keyboard is on it, and keeps it until the next
item takes it, so the player's focus restore lands back on the card. The first `j` takes the first
card you can see, not the top of the list.
- `VirtualGrid` takes part with `keyboardNav` (column count + scrolling an unmounted row in);
`VirtualFeed` turns it on, so the feed, the library and the channel page all have it.
- Keymap: two-step sequences (`g h`) whose pending step belongs to the scope that started it; the
page-level scopes (`page`, `search`, `list`) are quiet while a layer that owns the keyboard is open,
enforced in `dispatch`. A test pins the owner's rule that none of them needs a modifier on the
Hungarian layout.
- `g h/f/c/p/x/n/m/d/s/,` jump to a module this account can reach; `s` focuses the header search box
and selects the old query; Escape in it hands the keyboard back to the page (Plex's typeahead spends
its first Escape on its panel).
- Hover popovers are passive layers: an open tooltip still takes Escape first but no longer silences
the page keys.
- Focus ring (owner decision D2 = B): solid 2px accent around the whole item; the app-wide button/
link/row ring goes from 60% to solid too. The item keeps a transparent resting outline because the
video card transitions `all` — without it every `j` flashed a 3px white ring (measured in Chrome).
- Help sheet: the new keys, in a fixed order after the surface's own; a `g` chord only for a reachable
module; opened over a player or dialog it leaves out the page-level keys and the context-menu key,
which nothing can reach there (the latter pre-existing since E10).
- CLAUDE.md: a canonical-patterns row for list/grid keys (`useListNav` + `navItemAttrs` +
`data-nav-open`, not a private arrow-key handler).
