feat: workspace file editor, VS Code API-key fix, and English-only docs

[elkaix]

Related Issue

No filed issue. Three problems drove this branch:

1. Every turn on a Codex-signed-in model failed with Service temporarily unavailable — 400 status code (no body).
2. The workspace file editor (added on this branch) never opened, and its reload/save paths were broken.
3. VS Code walled API-key-only users behind a sign-in screen they could not satisfy.

Problem

Codex turns always failed. The gateway answers {"detail":"Unsupported parameter: max_output_tokens"}. The OpenAI SDK discards that body because it is not an {"error":{...}} envelope, so the message degrades to the literal 400 status code (no body) and nothing in our code ever sees the reason. The completion-budget resolver always produces a value, so the parameter was on every request. The same catalog also advertises an ultra reasoning level that /responses rejects outright.

The file editor could not open. Monaco validates every theme color against /^#?([0-9A-Fa-f]{6})([0-9A-Fa-f]{2})?$/ and throwsIllegal value for token color. Several design tokens (--color-text-muted, --p-selection) are declared as rgba(), so setTheme rejected on boot in both light and dark. Behind that: loadBuffer disposed the model it then reused (a reload re-enters with the same URI), a reused model never received the re-read text, a save superseded by a reload latched the saving flag true and disabled Save for the session, and save resolved the session at call time so switching sessions wrote the buffer into the wrong workspace.

VS Code sign-in. The init router reported not-logged-in whenever the login check was false even with models configured — and that check is true only for a Pythinker account or a provider OAuth token. A plain API key gives neither, and Skip was component state, so the wall returned on every reload.

Gates could not have caught the editor bugs.apps/pythinker-code/dist-web is generated from apps/pythinker-web and read by no typecheck, lint, or test; the check that guarded it only asserted the bundle existed, and nothing invoked it.

What changed

Provider

• Drop max_output_tokens for the Codex gateway, applied once after the request kwargs are assembled so both a configured value and a per-turn budget are covered.
• Stop writing the unusable ultra reasoning level into the config.

Web UI

• Normalize design tokens to hex before Monaco sees them; a test asserts every palette token in style.css matches Monaco's own regex.
• Create the editor model once per URI, write pending content into a reused model, attach the change listener after the value is applied so a reload does not land dirty.
• Clear the saving flag unconditionally; write back to the session the buffer was opened from.
• Stop a settled thinking step animating in the activity header for the rest of the run.

Gateway / desktop / VS Code

• Route-scoped bodyLimit on the fs action route (a 10 MiB write is ~13.4 MiB base64-encoded, past Fastify's 1 MiB default), so FS_TOO_LARGE is reachable instead of a transport rejection.
• Redact the Host bearer token from captured output — it reached both stderr and the pre-readiness failure Error.
• A configured model now decides ready on its own; apply only the newest provider refresh, and invalidate a superseded selection rollback.
• Opt-in seeded config profile for the dev extension host.

Build gate

• copy-web-assets records a fingerprint of every web build input; check-web-assets recomputes it and fails on a stale bundle. Wired into pre-push, the CLI build, and prepack. pnpm run build:web rebuilds and restages in one step.

Docs

• Point the doc skills at paths that exist, drop a bilingual parity check left over from the removed second locale, and remove the Chinese docs tree.

Checklist

• pnpm test — 20309 passed, 0 failed (1220 files)
• pnpm run typecheck — 0 errors (plus both apps/vscode configs)
• pnpm run lint — 0 errors
• node scripts/upstream-sync/check-managed.mjs, pnpm run sherif, nix build .#pythinker-code
• Every fix mutation-tested: reverting it turns its test red
• Changesets added

173-207: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Keep state.saving owned by its save request.

A save for file A can remain in flight after openFileEditor clears state.saving. A save for file B can then start. When file A finishes, Line 207 clears the flag for file B. The user can start a duplicate write, and the later write can report a conflict after the first write succeeded.

Track the save owner separately. Clear state.saving only when the completing save still owns it. Clear that owner in reset and openFileEditor.

Proposed fix

 let requestSeq = 0;
+let savingSeq: number | null = null;
const seq = ++requestSeq;
+ savingSeq = seq;
state.saving = true;
} finally {
- state.saving = false;+ if (savingSeq === seq) {+ state.saving = false;+ savingSeq = null;+ }

Pass force and baseEtag directly.

Use a direct boolean parameter for this single-parameter internal method. Pass baseEtag: undefined when the write must bypass optimistic concurrency. Do not change the request object shape with a conditional spread.

Proposed fix

-export async function saveFileEditor(options?: { force?: boolean }): Promise<void> {+export async function saveFileEditor(force = false): Promise<void> {
// ...
const result = await getPythinkerWebApi().writeFile(sid, {
path,

- ...(options?.force === true || etag === null ? {} : { baseEtag: etag }),+ baseEtag: force || etag === null ? undefined : etag,
});

As per coding guidelines: “For optional object properties, pass undefined directly instead of using conditional spread.” Also: “Single-param internal methods stay single-param — no options-object wrapping.”

In `@packages/agent-gateway/src/routes/fs.ts`:
- Line 275: Update fsActionResponseSchema to include an error-envelope variant
covering ErrorCode.FS_PERMISSION_DENIED and all other filesystem error codes, so
the public OpenAPI response documents the same errors defined by the route’s
defineRoute.errors alongside the existing success variants.

Nitpick comments:
In `@apps/desktop/src/host-supervisor.ts`:
- Around line 61-68: Update the JSDoc for the push() and finalize() methods in
the readiness interface to describe their HostReady result, including the origin
field and optional token field, instead of referring only to a loopback origin.
Keep the documented return behavior aligned with the existing HostReady type and
runtime contract.
