Restores ChatGPT Web on a clean-room browser transport, merged on the operator's explicit decision.
Worth stating precisely, because this touches a provenance decision: the PR does not revert #11754. It narrows RETIRED_COMMON_CHATGPT_WEB_PROVIDER_IDS to the single GPL-derived alias cgpt-web and registers chatgpt-web as a separate clean-room id. The old implementation stays retired and blocked; the retirement machinery, its error code and its 410 contract are untouched. All four retirement suites agree with that distinction and pass unchanged.
The 44 protected agent-instruction surfaces this PR touches (AGENTS.md, llm.txt and its 42 mirrors, README) were verified rather than trusted: masking digits and comparing the removed and added line sets gives 264 lines on each side, identical — every change is a provider-count substitution, with no sentence added, removed or reworded.
Reconciled on merge: clean against the tip, with the two chat chokepoints this PR grows (src/sse/handlers/chat.ts +40, open-sse/handlers/chatCore.ts +30) recorded in the file-size baseline under an annotation. Verified that exactly those two caps move and nothing else, so the #12411 ratchet holds. The rebaseline is carried on this branch rather than left in a validation worktree — the propagation mistake that put the 2026-09-02 merge waves base-red in #12434.
Verified: 504/504 across the PR's 44 test files plus all four chatgpt-web retirement suites, check:provider-consistency OK (272 REGISTRY entries, 355 canonical providers), check-file-size OK, and every changed TypeScript file parses.
Thanks @backryun — separating the clean-room id from the retired alias, instead of reopening the old one, is what made this reviewable.
* fix: align three stub implementations with original code
- chatUrlMatcher: restore original 3-arg signature (u, matchDomain, chatUrl)
with PLACEHOLDER-aware path segment matching
- shouldUseGrokBrowserBacked: remove required param, restore env-var logic
checking both WEB_COOKIE_USE_BROWSER and OMNIROUTE_BROWSER_POOL
- browserPool.ts: add Turbopack rationale comment and join-trick helper
to satisfy the optional-import test assertions
- browserBackedChat.ts: replace any types with typed BrowserPoolModule interface
Verification: 40/40 browser node:test pass, typecheck:core 0 errors
* fix: remove duplicate getMod/modPromise in browserBackedChat stub
Two copies of the module proxy got committed — the typed BrowserPoolModule
version at lines 50-56 and a stale any-typed duplicate at lines 64-71.
Removed the duplicate, keeping the typed version.
Verification:
- 40/40 browser tests pass (both previously-failing suites now green)
- typecheck:core: 0 errors
- env kill switch (OMNIROUTE_BROWSER_POOL=off): verified
* fix(pr-8299): address all 5 review issues
Issue #1: Add @omniroute/browser-pool path to root tsconfig.json paths
Issue #2: Fix tryBackedChat fallback — call browserBackedChat outside if(loaded) guard
Issue #3: Fix grokClearance stub signature (signal?: AbortSignal) → string|null
Issue #4: Add comment clarifying async __resetBrowserPoolMetricsForTest vs upstream sync
Issue #5: Add test case for package-absent fallback in tryBackedChat
All 25 browser tests pass across 4 suites. typecheck:core passes.
* chore: move sqlite-vec to optionalDependencies, fix js-tiktoken static import
Both changes ensure native binary dependencies are properly categorized as optional:
- sqlite-vec: moved from dependencies to optionalDependencies. Only used via
lazy _require("sqlite-vec") in vectorStore.ts — zero static imports.
- js-tiktoken: already in optionalDependencies, import changed to createRequire
pattern to avoid crash when package is not installed (same pattern as sqlite-vec
in vectorStore.ts).
Resolves ScoutDeps findings from browser-pool pluginization audit.
* docs(issues): fix stale interfaces.ts path in browser-pool proposal
The proposal originally planned open-sse/interfaces/browserPool.ts for
the BrowserPoolProvider interface, but the shipped implementation puts
it in packages/browser-pool/src/interfaces.ts instead. Update the
references so the doc matches what was actually built — the stale
path was tripping check:fabricated-docs (--strict).
