Four independent reviewers audited the result. Their findings define wp1's +diff: + +### 1.

EU and FedStart tenants return a different host +(`eu.windsurf.com/_route/api_server`, `windsurf.fedstart.com/_route/api_server`), so +those accounts log in and then send every call to the wrong server. GitHub Copilot +already threads `credential.apiBaseUrl` through; Devin must do the same, falling back +to the default host only when RegisterUser returned nothing. + +### 2. Portal/register override (major, real runtime failure) + +Login always signs in against `DEFAULT_REGION`. `src/oauth/devin/types.ts` documents +a `--portal-url` override that nothing wires, so a non-US tenant never reaches its +matching RegisterUser host. Honor the override and persist it next to the api-server +URL on the credential. + +### 3. Model-id normalization (minor, degraded path) + +`src/adapters/devin.ts` has no dotted-to-hyphen map. With the live catalog missing we +append `-medium` to the raw id, turning `swe-1.6` into `swe-1.6-medium`, which +Cognition answers with an opaque `permission_denied`.

Verdicts below are mine +after reading the cited code. + +## Accepted — blocker + +**Raw upstream bodies in auth error messages.** `register-user.ts:96,113` and +`cloud-direct/auth.ts:99,126` copy the response body into `Error.message`. That +message reaches CLI output, the adapter's `emit({ type: "error" })`, and +`/api/logs`. A Connect error that echoes `firebase_id_token`, or a 200 whose +`user_jwt` fails the shape regex, publishes a live credential; `redactSecretString` +does not match a bare `eyJ…` JWT. Confirmed by reading both files. Fix: status plus +allowlisted Connect code plus trace id, never the body. + +## Accepted — major + +1. **Tenant api-server routing.** `credential.apiBaseUrl` is written at login but + no call site reads it, and `store.ts:461` only persists Copilot origins, so an + EU/FedStart host is dropped on the next load anyway. Thread it through + `mintUserJwt`, the catalog fetch, and `streamChatEvents`, and teach the store to + persist a validated Devin origin. +2. **Redirect following on credential POSTs.** Both credential POSTs use the default + `redirect: "follow"`, so a 307/308 forwards the Firebase token or the protobuf + `api_key` to an attacker-chosen `Location`. Set `redirect: "error"` and validate + the host the same way `validateCopilotApiBaseUrl` does. +3. **Credential shape.** `refresh: ""` makes `detectOAuthWarning` report + `stale_credentials` for every Devin account from the moment of login, and + `refreshDevinToken` extends the expiry without contacting Cognition, so a revoked + key keeps looking valid. Use the durable-key house pattern: `refresh` carries the + key, expiry is effectively unbounded, and refresh throws so a 401 marks + `needsReauth`. +4. **Paste parsing.** `loginDevin` posts the entire pasted string as + `firebase_id_token`. The on-screen value is a token, but a user who pastes the + callback URL instead sends a URL. Parse a fragment/query token out of a URL paste + and reject a paste that contains no token. +5. **`clearCachedUserJwt` is never called.** The cached `user_jwt` (its payload + contains `api_key`) survives logout in process memory. Wire it into the Devin + logout path. + +## Accepted — minor + +6. `result.name` overwrites the JWT `email` with a display name, so reauth identity + comparison collides. Keep the email; the name is not an identity. +7. `registerUser` does not receive `ctrl.signal`, so cancelling login does not abort + the exchange. +8.

Client version strings `3.9.19`, + `2.0.0` and `1.48.2` in Metadata fields 2 and 7 all fail identically, so the + version pin is not the cause — the comment in `metadata.ts` claiming a version + mismatch produces exactly this error is no longer a sufficient explanation. + The version default was still moved to the shipped `3.9.19` with an + `OPENCODEX_DEVIN_CLIENT_VERSION` override, because `2.0.0` predates the rebrand + and nothing argues for keeping it. + + This is the open item.

Our carried files reference + `opencode auth login`, `syncedViaOpencodeAuth` and an + `opencode-windsurf-auth` CLI in `src/oauth/devin/types.ts`, so #4078 very + likely derives from it. Its license and the derivation are being checked; if + it is derived, attribution is required before this merges. + +`quangdang46/openproxy` talks to a different product (gRPC-web +`LanguageServerService`), so it is a secondary reference only. + +## wp2 outcome: the cloud chat path stays unverified + +Every request-shape hypothesis was tried against the live account and none of +them changed the trailer. In probe order: client version `3.9.19`, `2.0.0`, +`1.48.2`; the Connect request frame sent uncompressed with +`Connect-Content-Encoding` dropped; `Metadata` #31 filled with 732 hex +characters; `GetChatMessageRequest` #2, #15 and #20 added and #22 dropped on the +first turn; `ChatMessagePrompt` #1 `message_id` added; `Authorization: Basic` +in both base64 and raw doubled-key forms; and both hosts. Same +`invalid_argument: an internal error occurred` every time, with a fresh trace id. + +The model gate is provably fine. `swe-2-high` and `claude-sonnet-5-medium` are +refused locally as disabled, and a bogus uid is refused as unlisted, so the +failure is specific to `swe-1-6-slow` — the one model a free account has, and a +"slow" lane at that. + +**Entitlement now outranks request shape as the explanation.** The site +advertises "Slow Devin Cloud access with limited quotas" for free accounts, and a +slow lane plausibly is not served by this RPC at all. #4078's author reported a +live PONG on 2026-09-09 with the *original* field set, which is the deciding +fact: shipping unverified wire changes would risk regressing an account that +works today in exchange for no measured gain here. The whole experimental delta +was reverted; only the wp1 hardening and the MIT notice remain. + +Confirming this needs a paid account or a captured working request.

The failure was never about the +plan. + +Isolating it took one decisive move. The most actively maintained reference +(`dwgx/WindsurfAPI`) is zero-dependency ESM, so its request builder can simply be +imported. Building a turn with the reference builder and sending it through our +own transport returned **HTTP 200** and a real Connect stream — which proved the +transport, the headers and the credential were all fine, and put the fault in our +request encoder. Diffing the two encoded messages field by field left exactly one +difference: `CompletionConfiguration` (#8). + + reference #1=1 #2=8192 #3=128000 #5=double #7=40 #8=double + ours #1=1 #2=64000 #3=32 #5=double #6=double #7=50 #8=double #11=double + +**#2 is the output cap and #3 is the context window; we had them swapped.** A +caller asking for 32 output tokens wrote 32 into the context-window field, and +Cognition answered with an opaque `invalid_argument: an internal error occurred`. +That is why every account failed identically and why no amount of probing the +transport helped. The reference's own comments record the same mis-tagging and +the same re-calibration. + +A second, independent trap sat behind it: **a temperature of exactly 0 is +refused** with the same opaque error.
