The visualizer's PCM cache decoded the entire episode into RAM (22050 Hz
mono s16 ~160 MB/hr of audio) and held it until stop() — a 3-hour episode
pinned ~500 MB and long-form content hit 2.5 GB. The 4x decode also pulled
the whole remote file even when only minutes were listened to.
- audio-pcm-cache: sliding window around the playback position — the
decode head caps at maxAheadSec (600s) ahead of the cursor, segments
older than keepBehindSec (300s) are pruned, and the tail refills as
playback advances. Steady state ~40 MB regardless of episode length;
a backward seek past the window restarts a segment there (the existing
seek-hole mechanism, no new failure mode).
- feed: cap the full-parse episode cache at 1000 episodes/feed so
archive-heavy subscriptions can't pin their entire history in RAM;
the visible list stays bounded by the user's cache preference and
fetch-more keeps working within the ceiling.
- tests: pin the new head-cap and prune contracts (8/8 in
audio-pcm-cache.test.ts; full suite 193 pass).
Also includes the in-flight cleanup/refactor pass (cover-art resolve
helper, page and comment tightening, ESLint config removal).
Add the shared parent | current | preview row primitive that implements
yazi's mgr.ratio = [1, 3, 3] contract via Yoga flexGrow, so every list
tab renders an identical, layout-stable shell regardless of terminal
size.
- New YaziPaneRow component: three bordered columns grow at 1/7 : 3/7
: 3/7 with flexBasis=0 (content can never stretch its slot). The
current column carries the accent focus ring when `focused` is
truthy; parent and preview stay muted. The blank parent keeps its
1/7 slot with a muted placeholder rather than collapsing.
- PANE_RATIO.current 4 -> 3 to match yazi's [1, 3, 3].
- Add render-based tests covering the 1:3:3 ratios (incl. null
parent/preview) and the focused/unfocused accent ring behavior.
- Configure the bun test preload for the solid JSX transform.
