Six findings from reviewing the accumulated blitz/spawn-v2 diff:
- loadRecents restored the seeded cwd but never emitted it, so the leaf's
draft kept cwd:"" and the next render reseeded the form blank.
- stripDrafts did not recurse, so every half-filled draft in a split tab
was written to localStorage; the old test passed only because hydrate
discards draft on the way back in.
- showRawCwd and selectPreset grabbed focus from async init paths, so a
draft pane stole the caret seconds after mounting.
- .mv-draft inherited no layout once the form left .modal-body.
- onSuccess mounted the new session onto a leaf that may have been closed
while the POST was in flight, stranding it in no pane.
The browser app had no tests and no way to run any: package.json shipped
dev/build/preview/typecheck, and CI installed Node and pnpm but never ran
anything with them. Its densest logic was module-private, so even with a
runner none of it was reachable.
Extracts four pure modules out of DOM-heavy ones — tree.ts (directory
grouping), keys.ts (terminal escape encoding), paths.ts (completion
arithmetic), html.ts (one escaper, replacing four copies). Extraction
rather than `export` because attach.ts imports xterm's CSS at module
level, which a node test cannot load.
CatalogStore takes an injectable socket factory, scheduler and refetch, so
the reducer and the backoff schedule run without a server. snapshot() now
returns a copy: it returned the live object while events mutated it in
place, so listeners could not diff and every event rebuilt the whole tree.
36 tests across 6 files, and a `web` CI job running typecheck, test and
build. vitest is pinned to 2.x — 4.x requires vite >= 6 and this is vite 5.
