Adds the spike write-up and re-opens finding 2 of
playback-backend-unification.md, which concluded that video cannot unify
on a native engine because the webview owns the surface.
That finding's general form has since been falsified on Android, where
native video composites behind a transparent WebView and ships on by
default. The evidence behind it was also entirely about foreign-window
embedding -- mpv's render API, drawing into a GL context we own inside
Tauri's own GTK tree, was never tested. The spike tests that one claim
and comes back green on Linux for both X11 and Wayland, bar the Tauri
default_vbox() half of G1.
Findings 3-6 are deliberately left standing. Finding 3 in particular --
mpv has no adaptive bitrate -- is an independent disqualifier that a
green compositing result does not clear, and the spike says so rather
than reading as a green light.
The next-free-id line moves to UR-079 / IR-033 / DR-219: this branch
allocated UR-077 and UR-078 for the updater and diagnostics work, and
DR-215 through DR-218 with them, after that line was last written.
Authored in a parallel session working in the same checkout; committed
here so it travels with the rest of the branch.
A spec was a promise; sixteen of them had become descriptions of code that
already shipped, sitting beside four that describe work still outstanding, with
nothing in the file telling the two apart. Half the statuses were also wrong —
audio-equalizer read "Accepted" with the EQ live on both platforms, the native
video spec said the flag stays off after the default was flipped on.
The shipped designs move into docs/architecture, which is the maintained
description of the build, and the spec files go. Git history keeps the
originals; what a future change still needs is carried across:
- 01-rust-backend: favourites rewritten (the old section named a file that no
longer exists and called shipped buttons "planned"), domain vocabulary owned
by Rust (SearchScope, exclusions, the bitrate ladder), background workers
- 02-svelte-frontend: app shell and chrome, library mosaic, series/episode
navigation, downloaded browse, safe-area insets, native-video store, logging
- 03-data-flow: locally-indexed search
- 05-platform-backends: audio settings on ExoPlayer, the equalizer's band
vocabulary, native video compositing, the background-audio handoff
- 06-downloads-and-offline: one storage model, offline catalog visibility
- 09-security: path confinement and input binding
docs/specs/README.md now says what the directory is for and where each shipped
design went. Deferred work the specs recorded is kept beside the code it
concerns rather than lost: season-bounded autoplay, the two dead search
commands, why indexing is a full crawl.
requirements.md had fourteen stale statuses — Android audio parity still read
"Linux only", DR-150 still said the native-video default was off, DR-190 was
Proposed after DR-196 implemented it, and five tooling requirements were
Proposed after landing. Three unbuilt specs suggested requirement ids that have
since been allocated to other work; each now carries a warning.
