fix(search): bind Devin OAuth to routed provider

[luvs01]

Summary

• A routed provider that reuses the Devin OAuth definition still validated the tenant URL and credential against the literal provider name, so the routed account silently spent the wrong credential; search.ts also hardcoded "devin" instead of the route's provider.
• accessSnapshot/resolveAccessSnapshotForAccount/getValidAccessTokenSnapshot now take an oauthProvider parameter so the routed provider keeps its own credential and tenant base, and the executor/search paths pass the actual provider name.

Verification

• bun test tests/server/api-key-scope-alpha-search.test.ts and related suites green on the fork branch at head.
• Checked against open fix(oauth): keep Meta Muse login continuations current #5911/fix(oauth): expose live device hints and hide callback paste #5915: the only shared file is src/oauth/index.ts and the hunks sit ~1100 lines apart in disjoint functions, so this merges cleanly alongside either outcome.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed.
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Summary by CodeRabbit

• Bug Fixes
  • Devin alpha search now uses the selected provider’s credentials and API host, including when using a custom Devin OAuth provider.
  • OAuth token refreshes retain the selected provider definition, keeping initial and refreshed access consistent.

📝 Walkthrough

Walkthrough

OAuth token resolution now separates the routed provider from the OAuth provider definition used for validation. Devin alpha-search credential lookup uses the routed provider name. New tests cover custom Devin providers and tenant-specific API base URLs.

Changes

Devin OAuth routing

Layer / File(s)	Summary
OAuth definition selection src/oauth/index.ts	getValidAccessTokenSnapshot accepts an optional oauthProvider definition ID. Token resolution uses that definition for provider lookup and API-origin validation, including after refresh, while the routed provider still selects the active account.
Devin alpha-search credential routing src/server/search.ts, src/web-search/devin-executor.ts, structure/runtime.md, tests/server/api-key-scope-alpha-search.test.ts	The Devin search handler passes the routed provider name instead of a hard-coded provider name. The web-search executor explicitly selects the Devin OAuth definition. Documentation reflects the routed-provider credential lookup. Tests check custom credentials and tenant-specific API base URLs.

Priority: ⬇️ Low

Change: Bug fix

Merge Risk: ⚪ Minimal · up to 49e60

The routed credential behavior has no established production defect. Strengthening the test assertion can be handled as a follow-up.

Review details

Systems and components

• observed — src (service) was modified; 3 changed files map to changed impact.
• observed — structure (service) was modified; 1 changed file maps to changed impact.
• observed — tests (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in src/oauth/index.ts: accessSnapshot now accepts an OAuth definition ID, defaulting to the routed provider ID.
• observed — Modified behavior in src/oauth/index.ts: Account API-origin validation now uses the OAuth definition ID rather than the routed provider ID, so custom provider slots using the Copilot or Devin definition receive that definition’s validation.
• observed — Modified behavior in src/oauth/index.ts: resolveAccessSnapshotForAccount now accepts an OAuth definition ID, looks up the provider definition by that ID, and reports it as unsupported if no definition exists.
• observed — Modified behavior in src/oauth/index.ts: The resolver passes the OAuth definition ID into snapshot construction, applying the matching account-origin validation.

이 PR은 웹 검색이 Devin 로그인 키를 엉뚱한 칸에서 꺼내 쓰던 일을 고칩니다.

team-devin처럼 이름을 따로 만든 제공자가 Devin 방식을 써도, 검색은 항상 이름이 정확히 devin인 칸의 키를 보냈습니다. 그 칸에 적어 둔 서버 주소도 이름이 devin일 때만 검사해서, 유럽 주소는 사라지고 미국 기본 주소로 키가 나갔습니다.

고친 뒤 검색은 요청이 가리킨 그 칸의 키를 씁니다. 서버 주소를 검사하고 만료된 키를 새로 받는 규칙만 원래 Devin 규칙을 그대로 씁니다. 허용되지 않은 주소는 버리고 기본 주소로 갑니다. 예전 이름 devin-cli는 계속 devin 칸을 봅니다. 테스트는 두 가지를 확인합니다. 다른 칸의 키가 요청에 안 섞이는지, 허용된 유럽 주소로 요청이 가는지입니다. 기준 브랜치는 dev이고, 이 변경과 겹쳐 닫아야 할 다른 열린 PR은 없습니다.

src/web-search/devin-executor.ts resolveDevinWebSearchSnapshot - 키는 요청이 고른 칸에서 읽고, 로그인 규칙 이름은 항상 devin으로 고정합니다. Devin 로그인 규칙이 그 이름 하나뿐이라 이 고정은 맞습니다.

src/server/responses/request-transport.ts getValidAccessTokenSnapshot - 대화 요청은 칸 이름을 로그인 규칙 이름으로도 씁니다. team-devin은 로그인 규칙 목록에 없어서 대화는 거절됩니다. 이번 수정은 검색에만 있습니다.

tests/server/api-key-scope-alpha-search.test.ts - 넣은 키는 만료 시각이 아주 멉니다. 키가 거의 만료돼서 새로 받을 때, 새 키가 team-devin 칸에 저장되는지는 테스트가 보지 않습니다.

메인테이너의 판단이 필요한 지점

• 검색만 고치고 머지할지, 대화도 같은 방식으로 고칠지.
• 키가 만료되기 직전인 경우를 테스트에 넣을지.

너의 추천
검색은 이대로 dev에 머지하면 됩니다. 다른 칸의 키가 검색으로 나가던 길은 막혔고, 서버 주소는 원래 허용 목록을 그대로 탑니다. 대화까지 같은 PR에 넣으면 범위가 커지니, 검색 머지 뒤에 따로 보는 편이 좋습니다.

Approved exact head 49e6030. Routed search now admits, selects, and spends the same provider slot while applying Devin-specific OAuth validation without transferring credential ownership. Destination allowlisting, generation checks, fail-closed account usability, and redirect rejection remain intact. Exact-head CI run 36288275015 passed the executed Linux shards, gates, and integrations; Windows/macOS full shards and the privacy job were skipped, so this approval does not claim those ran. Nonblocking follow-up: add an explicit custom-slot missing or re-auth-required no-fallback regression.

Landed on dev in #6061 (merge 06d7914e6a) as one squashed commit that keeps your authorship. Thank you. Closing because this repository merges into dev, so GitHub does not close carried PRs automatically.
