中文：复用 Zed 账号凭据接入托管模型并保留真实 UAT 与条款风险边界
Scrub upstream error bodies on the account lookup and LLM token exchange, and route fetch and body-read rejections on those calls and on the /completions fetch through scrubZedRejection. A rejection that carries neither value is rethrown by identity, so a clean abort stays the same object; one that carries either is replaced with the same name (a DOMException stays a DOMException) and numeric status, without cause.

…t presets provider-routes.ts sits at the 2000-line file-size threshold with no cap, so the Zed probe moves to zed-provider-probe.ts behind a one-line dynamic import and the file ends at 1999 lines. The registry now holds 101 presets (83 key-based, 14 OAuth), so the anchored count sentence in all eight provider guides, all eight quickstarts and the structure ops record follows.

Merge Risk: 🔵 Low · up to The opt-in provider has no established merge-blocking defect in the supplied evidence. Correct the roster documentation; real-account end-to-end behavior remains unverified. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The integration is opt-in and uses account-specific credentials, with bounded discovery and cancellation controls. Its completion transport can use a configurable destination, however, and the restrictions on that destination were not fully established. Callback identity validation also depends on an upstream contract that was not available for review. No actual credential disclosure or unprivileged exploit was demonstrated. Retained concerns

Review comments at @gui/src/pages/providers-shared.ts:
- Line 58: Update the Zed label handling in oauthLabel so the provider name
remains unchanged while the experimental qualifier is resolved through a locale
key using the existing translator; add that key to the GUI locale files.
Review comments at @src/adapters/zed.ts:
- Around line 110-127: In the Zed event-stream TransformStream, stop processing
chunks and flushing buffered data once `finished` is true, so no frames reach
`processLine` after a terminal frame. Cap the newline-free `buffer` length and,
when it exceeds the limit, emit a native error payload, mark the stream
finished, and clear the buffer.
Review comments at @src/codex/catalog/provider-models.ts:
- Around line 367-372: Add deadline and cancellation to all Zed roster calls: in
src/codex/catalog/provider-models.ts lines 367-372, pass an 8-second timeout
signal to resolveZedModels; in src/server/management/zed-provider-probe.ts lines
23-28, add an 8-second timeout signal to the forceRefresh options; and in
src/adapters/zed.ts lines 181-188, combine incoming.abortSignal with an 8-second
timeout using AbortSignal.any and pass the combined signal through.
Review comments at @src/oauth/zed.ts:
- Around line 91-100: Update the manual-input branch in the Zed login flow to
stop requesting or processing input once login has settled, and cancel any
pending ctrl.onManualCodeInput operation when callback wins; a settlement guard
alone is insufficient while the prompt remains pending. Preserve the existing
Promise.race outcome behavior.
Review comments at @src/server/responses/request-transport.ts:
- Around line 725-727: Carry the Zed credential user ID separately on
OAuthAccessSnapshot, populate it from credential.accountId, and use it for
_zedAuthContext.userId in request-transport.ts:302-306 and 725-727 and for the
resolveZedModels call in provider-models.ts:347-352. Keep
OAuthAccessSnapshot.accountId unchanged for store lookup, account selection, and
cache ownership.
Review comments at @tests/adapters/adapter-tool-conformance.test.ts:
- Line 431: Remove “zed” from TOOL_LESS_ADAPTERS and add registry-wide tool
conformance coverage that stubs Zed’s catalog fetch, unwraps provider_request,
and delegates to the inner provider driver. Verify tool names survive Zed’s
post-processing, including freeform restoration, namespaced collisions, and
hostile-input restoration.
Review comments at @tests/providers/zed-hosted-provider.test.ts:
- Line 81: Remove the stray unary plus before the credential-bearing rejections
`describe` call so the test suite registers the block normally. Keep the
existing `describe` callback and its contents unchanged.

The access snapshot now carries providerUserId, Zed's own user_id from the login callback. Transport, catalog discovery and the connection probe used the store slot id, a hash, so Zed rejected every real account. The completion stream fails closed: a malformed or non-object frame, an oversized unterminated frame, a partial trailing frame, or an EOF with neither the stream-ended status the request asks for nor a native terminal becomes a provider-native error. Nothing is forwarded after a terminal. Zed catalog calls now carry an 8 s deadline (and the request abort in the adapter), the manual-paste login branch stops once the race settles, and the GUI account label keeps only the brand. Review findings on #6362.
Mid-stream failure statuses and formatErrorBody passed upstream text only through the generic redactor; they now also remove this request's Zed token and user id. Corrects the stream comment: frames after a native terminal event still pass because Chat-with-usage sends a usage chunk after finish_reason. Follow-up to the independent security review of 77a58ee.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
State both uses of the live model roster.
Line 1179 says the roster is used for picker metadata “only,” then says the live provider field supplies the backend family. In src/adapters/zed.ts (Lines 224–377), buildRequest resolves the catalog and passes it to providerFromCatalog, so the roster also informs backend-family selection. Remove “only” and describe both roles.
Proposed wording
-The live `/models` roster is used for account-specific picker metadata only: arbitrary model ids remain
-forwardable, with the backend family inferred from the live provider field or model name.
+The live `/models` roster supplies account-specific picker metadata and can also provide the
+backend-family hint for a listed model. Arbitrary model ids remain forwardable, with the backend
+family inferred from the live provider field or model name.As per path instructions, “Check that user-facing docs stay in sync with actual CLI/API behavior.”

Summary
Adds Zed Hosted AI (experimental) as an opt-in OAuth provider, carried from #5912 by @andrew05060414. A user who signs in with
ocx login zedcan route Codex or Claude Code requests to the models included in their Zed plan. Without a Zed login, nothing changes: the provider stays inactive and is not added to any default.This is an unofficial, use-at-your-own-risk (UAYOR) bridge. It is not endorsed by Zed, it spends the signed-in account's hosted-model entitlement outside the Zed editor, and Zed may limit or suspend the account. The maintainers chose to ship it on that basis. The dashboard routes Zed through the elevated ToS-risk gate: login stays disabled until the user ticks the risk acknowledgement. The provider guide, the provider configuration reference and the adapter reference say the same.
What the provider does:
src/oauth/zed.ts) and keeps a durable account identity.src/providers/zed.ts)./completionsenvelope, and translates the streamed events back (src/adapters/zed.ts).Maintainer changes on top of the original carry:
/completionsfetch, go throughscrubZedRejection. A rejection that carries neither value is rethrown as the same object, so a clean abort keeps its identity. One that carries either is replaced, keeping its name (anAbortErrorstays aDOMExceptionAbortError) and any numericstatus, and the original is not kept ascause.src/server/management/zed-provider-probe.tsbehind a one-line dynamic import, becauseprovider-routes.tshas no size cap and sits at the 2000-line threshold. It ends at 1999 lines.structure/ops/docs-and-release.md.Supersedes #5912.
