* fix(native-chat): stop the spinner on a not-yet-flushed transcript
A brand-new agent session can take minutes to write its first JSONL line,
and one that is never prompted never writes it at all. The host emitted no
stream frame until the file resolved, so every native-chat client sat on a
bare spinner with the composer enabled but the transcript blank -- forever,
in the never-prompted case.
The resolve poll now reports the transcript as pending after a short grace,
and both host handlers emit a `pending: true` snapshot. It is deliberately
not a plain empty snapshot: an empty window sold as a settled read would
capture over retained history and unblock consumers that require a
trustworthy transcript (the launch-draft adoption would re-offer a prompt
the agent may already have taken).
Clients render it as the "start a chat" empty state while keeping the read
unsettled -- `awaiting-transcript` on mobile, an `awaiting` read phase on
desktop, which also stops the seed loop expiring into an error card for a
session that is simply new. New optional field only, so older clients
ignore it and still stop spinning.
* fix(native-chat): negotiate pending transcript frames
`src/preload/api-types.ts` was 3,752 raw lines (3,533 counted, 11.8x the
300-line budget) behind an `eslint-disable max-lines`. Almost all of it was a
single `PreloadApi` object type whose ~83 namespace properties were declared
inline, so any IPC surface change meant editing one 2,600-line type.
Give each namespace a named type in its own module under `src/preload/api/`
(`pty-api.ts`, `filesystem-api.ts`, `github-pull-request-api.ts`, ...) and
recompose `PreloadApi` from those names. `api-types.ts` keeps the `declare
global` Window augmentation and re-exports every moved name, so all 52 import
sites are untouched.
Two shapes needed care to stay type-identical rather than merely compatible:
- Three keys (`gh`, `git`, `ui`) are composed from two modules each. A plain
intersection is NOT identical to the original flat object literal, so those
use a `Merged<T>` mapped type; a negative control confirmed that dropping it
fails the parity assertion.
- Keys whose module groups several namespaces use indexed access
(`fs: FilesystemApi['fs']`) to preserve exact identity and source order.
`config/tsconfig.web.json` and `tsconfig.tc.web.json` enumerate files by path,
so they need `src/preload/api/**/*` alongside the existing `api-types.ts` seed
or the web projects fail TS6307.
Verified by exact type identity, not assignability: 41 assertions of the form
`Equals<Now.X, Before.X>` against a frozen pre-split snapshot, covering every
exported name, plus a per-key pass over all 83 `PreloadApi` keys. All three
projects typecheck clean with those assertions active.
Verification note: these tsconfigs are `composite: true`, and `tsc --noEmit`
will reuse a stale `.tsbuildinfo` and report clean for a state that genuinely
fails. Every result above was produced after deleting the buildinfo, including
a negative control confirming the gate still fails on deliberate drift.
Drops the `max-lines` bypass and its baseline entry (ratchet 346 -> 345).
