feat(oauth): import the Muse Code CLI credential behind a ToS warning - #3337
Conversation
wp4 plan plus the research it rests on. Five audit rounds; the reviewer failed it four times.
Adds `meta-muse`, an OAuth provider that reuses the API key the Muse Code CLI already holds, for operators who signed that CLI in and would rather not provision a second key. This ships because the repository owner authorized it for his own account. An earlier phase closed the same idea as a NOOP, and that reasoning stands: proving a credential works is not the same as being allowed to use it, so an agent must not spend a user's ToS risk on its own initiative. A user spending his own deliberately is a different act, and the repository already models it - anthropic and google-antigravity sit in the same HIGH_RISK map. Two measurements shaped the design. The credential file at ~/.config/muse/auth.json holds no secret; it is a pointer to a macOS Keychain item. That item carries both an access_token and an api_key, and only the api_key authenticates: the OAuth access token returns 401 invalid_api_key on /v1/models while the sibling key returns 200. So this is a static-key credential with nothing to refresh, the shape command-code already uses. Import-only, and macOS-only. `muse login` has no non-interactive mode, so a spawned child could outlive cancellation, and polling for the pointer file is satisfied instantly by the one already on disk - which would reimport the OLD account on a force-login. When no credential is present the provider says what to run instead of running it. The warning reaches both surfaces, which took two fixes: - The GUI map alone was not enough. Reauthentication called loginOAuth directly, so a user who had already logged in could refresh a high-risk credential without ever seeing the modal. onReauth now routes through the warning-aware path, carrying accountId so acknowledgement continues the same operation rather than a plain login against the active account. - login-cli.ts never reads the registry note, so `ocx login meta-muse` had no warning at all. loginMetaMuse emits it through ctrl.onProgress before it touches the pointer or the Keychain. The disclosures say what is actually known. Meta scopes this credential to its own CLI and how these calls settle is not observable from the API, so the note says treat every call as billable rather than asserting pay-as-you-go as fact. It also states that the key is copied into OpenCodex's auth store, because it is - runLogin persists it like every other OAuth credential. Also: two price overlays (overlays resolve by exact provider id, so a provider whose warning is 'treat every call as billable' would otherwise report no cost), a privacy-scan detector for the measured LLM|<digits>|<tail> key shape exercised through a new exported scanText seam, and a GUI test that asserts login, add-account and reauth each reach login zero times before acknowledgement and once after. supportsPerAccountQuota stays false, with a test. That predicate gates fetchAccountQuota, whose fallback sends any non-Kiro/non-Antigravity bearer to Anthropic's usage endpoint - flipping it without a dedicated branch would ship a Meta key to Anthropic. Quota is deferred to wp5: Meta does report subscription windows, but only as an SSE event on streaming turns, which needs a passive cache rather than a probe.

tests/lab-fabric-task.test.ts failed intermittently on the macOS CI lane and in local full-suite runs, with four or five failures in the same describe block. It read as a flake. It is not one. The tests shorten the fabric producer's isolation budget from the product's 30s/5s to 2000ms/750ms so a hung producer fails in about a second instead of stalling the suite. That budget starts counting when the parent spawns a Bun CHILD process. Spawning one while the rest of the suite saturates the CPU can take longer than 750ms by itself, so the child is killed for inactivity before it runs a line - and the assertion then sees whatever the harness makes of a killed producer: inactivity_timeout where it expected sandbox_violation, or blocked where it expected pass. That is deterministic under contention, not random. Eight parallel runs of the file reproduced five failures each, at a near-identical ~760ms, while a single run passes 49/49. It only looked flaky because it needs a busy machine, which is also why the same four tests passed on one CI run and failed on another. The fix mirrors the watchdogMs helper that already exists for the adjacent problem. watchdogMs bounds how long a TEST may run; isolationBudgetMs scales a PRODUCT budget a test deliberately shortened, with a floor that only applies under load (CI, or a full-suite lane) and leaves a lone local run untouched. The total budget is now a multiple of the inactivity budget rather than a fixed 2000ms. fabricActivityPatchExecutor sleeps 40% of the inactivity budget three times to prove activity resets the deadline, so it needs ~1.2x inactivity to finish; pinning the total while inactivity scaled up starved exactly the test that exercises the scaling. scripts/test.ts marks its spawned lanes with OCX_TEST_FULL_SUITE=1, since a lane running many files in parallel is the same contention as CI.
tests/provider-workspace-auth.test.ts pinned the exact call `loginOAuth(provider, true, accountId)` in the onReauth handler. That assertion was correct when it was written: its point is that re-authentication actually reaches login rather than dead-ending. It now conflicts with the fix in the previous commit. Reauth was calling loginOAuth directly, which meant a user who had already logged in could refresh a high-risk credential without ever seeing the Terms-of-Service warning - the map gated the first login and nothing after it. The assertion is updated rather than the code reverted, because the seam it guards is unchanged: requestLoginOAuth forwards the same (provider, addAccount, accountId) triple, and the continuation now carries accountId so acknowledging the warning resumes the same operation instead of a plain login against the active account. Both halves are asserted. Independently, CI confirms the CL-07 isolation-budget fix worked: all 49 tests in that file passed on the macOS lane, including the four that had been failing, with the activity test taking 6.07s under the scaled budget where the old 750ms budget killed its producer mid-spawn.
Both findings from CodeRabbit, and both were right. The privacy scanner printed finding.value to stderr on failure. For a home path or an email that is the context a reviewer needs. For a bearer token or an API key it means the scan that exists to keep a secret out of a readable artifact copies it into CI logs, which are more widely readable than the diff it was blocking. Credential-shaped kinds now report location and kind only. defaultReadKeychain waited on `security find-generic-password` with no deadline. That call can raise an interactive Keychain approval prompt, and on a headless or locked machine nobody answers it - so the login would hang before the 10s validation timeout was even created. It now races a 5s deadline combined with the caller's abort signal, and kills the child in a finally block so a prompt still on screen cannot outlive the race. Two tests: a blocked read fails with a bounded message rather than hanging, and the caller's signal actually reaches the reader.
