feat(meta-muse): accept a pasted Muse Code key on Windows and Linux - #3437
Conversation
📝 WalkthroughWalkthroughMeta Muse now accepts pasted API keys on Windows and Linux. Imported and pasted keys share validation. Refresh preserves credential origin. Registry, documentation, planning records, and tests describe and verify the new flow. ChangesMeta Muse cross-platform parity
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Cancelling manual Meta Muse key entry can leave login stuck. The user-facing and planning guidance also needs correction so unsupported input surfaces and Linux manual entry are described accurately before merge. Sequence Diagram(s)sequenceDiagram

When a Windows user follows this instruction and runs ocx login meta-muse inside WSL2, Bun reports process.platform === "linux"; the immediately following non-Darwin branch then rejects the import before reading any credential. Therefore “import there” is impossible in this implementation and sends users into a dead end. Either implement and verify Linux/WSL credential import or direct Windows users only to the supported meta-model key path.

This changes user-visible platform guidance in both the login error and registry note, but docs-site/src/content/docs/guides/providers.md:461-465 still publishes the old blanket explanation that non-macOS import is unavailable because the CLI key is in the macOS Keychain. Windows readers therefore continue receiving precisely the explanation this commit identifies as false. Update that section, and any applicable localized copies, to distinguish Windows from unverified Linux storage.

loginMetaMuse refused every non-darwin host with one message blaming the macOS Keychain. On Windows that reason is false: Meta ships no native Windows Muse Code CLI at all, so there is no credential store to look in, and a user who believed the message would go hunting for the wrong thing. Windows now names WSL2, which is Meta's own documented route. Linux names the real blocker, that its credential storage has not been measured, so an unverified shape is refused rather than guessed. Both point at the supported META_MODEL_API_KEY path. No reader is added. The pointer interface declares only mechanism, storage and user_email, so a Linux branch would have to invent the fields it reads. devlog 050 records the four facts a real Linux pointer would have to supply before that code can exist. The consent warning still fires before every refusal, including the new ones, since it is the CLI's only warning surface.
…o refuses Implementation review caught a contradiction in the message this branch just added: it told Windows users to install the CLI under WSL2 and import there, but WSL2 reports platform linux, which lands on the Linux refusal two lines below. The advice walked the user into a dead end. WSL2 is still named, because it is where the CLI can actually run. What changed is the promise: import stays unavailable on that path until the Linux credential storage is measured. The registry note and the plan doc say the same thing now. A regression test pins it, since this is a wording trap that would be easy to reintroduce.
Refusing these platforms was reporting a limitation of our importer as a limitation of the platform. Meta ships no Windows CLI and its Linux credential storage has never been measured, so there is nothing to read from disk -- but the same API key is visible in Meta's own developer console, so the user is not actually out of options. Off darwin the login now resolves with instructions and a paste field, the same shape kiro.ts uses when no local token exists. A host with no paste surface still refuses, and the message names where to get the key. The pasted key is not a weaker credential. Import and paste now share one validator: the same LLM| grammar check and the same live call against the Model API. A key that skipped either would differ from an imported one only by 401ing mid-session. It carries source manual and no email, since there is no pointer to read one from. The consent warning still fires first on every path.
…d docs Implementation review found five real problems in the paste path. The instructions told Linux users Meta ships no CLI for their platform. It does; only its credential storage is unmeasured. The two platforms are unavailable for different reasons and now say which. refreshMetaMuseToken hardcoded source local-cli, and merged() in index.ts only preserves a source that is not local-cli, so a pasted key would be relabeled as imported on its first refresh. It now takes the stored credential and keeps manual. Extracting the shared validator had quietly reworded two macOS errors. A refactor that rewrites a user-facing string is a behavior change in disguise, so the Keychain wording is restored verbatim. The no-failure-path-echoes-the-credential test only ever ran the macOS import path, so its name overclaimed as soon as a second route existed. It now covers imported and pasted origins against both a 401 and a dead socket, and asserts the canary is absent from onAuth as well. The providers guide, the registry note and its decision record all still described the provider as import-only and macOS-only.
The non-disclosure test threw its own 'should have failed' sentinel inside the try block and caught it in the same catch. A case that unexpectedly SUCCEEDED therefore produced an error whose message has no canary in it, and the test passed. It was asserting the sentinel, not the product. The failure is now tracked in its own flag and asserted before the non-disclosure checks. Driven red to prove it: pointing the pasted/rejected case at a 200 response fails the test. Two wording fixes alongside it. The branch with no paste surface told the user to paste when prompted, which is precisely what that branch cannot do; it now names where a prompt exists. And validation reported a pasted key as imported.
The dashboard paste field is the surface a Windows or Linux user reaches for meta-muse, and everything it accepts passes through parseCallbackInput and the shared submitManualLoginCode gate first. A Muse key has no code= and no #, so it depends on the raw branch to arrive intact. That is currently true and nothing states it. A future tightening of the gate -- requiring a state parameter, or splitting on # unconditionally -- would truncate the key into an invalid credential and the failure would surface as a 401 from Meta rather than as a parsing bug.

Settle manual login when the controller aborts.
OAuthController.onManualCodeInput has no abort contract. The management callback handles aborts, but the CLI callback in src/oauth/login-cli.ts:81-89 does not observe a signal. At src/oauth/meta-muse.ts:150, manualKeyCredential() can therefore keep loginMetaMuse pending when manual input remains pending. Race manual input with ctrl.signal when present, remove the abort listener after settlement, and add a regression test.

Summary
Meta Muse Code login refused every non-macOS host. That was reporting a limitation of our importer as a limitation of the platform: Meta ships no native Windows CLI and its Linux credential storage has never been measured, so there is nothing on disk to read - but the same API key is visible in Meta's own developer console, so the user is not actually out of options.
kiro.ts:405already uses when no local token exists: resolve the flow first so the dashboard renders its input, then block ononManualCodeInput.LLM|grammar check and the identical live call against the Model API. A key that skipped either would be a weaker credential wearing the same provider id, and the difference would surface only as a 401 mid-session.source: "manual"and no email, since there is no pointer to read one from.access === refreshas before, because this is a static key.macOS behavior is unchanged: the Keychain import path is untouched apart from calling the extracted validator.
Stacked on #3436. Retarget to
devonce the parent lands.Verification
bun test tests/meta-muse-oauth.test.ts- 33 pass, 0 fail, 76 assertions.dev.meta.ai; Linux offers the same; a pasted key still faces the grammar check and a 401 still fails; a host with no paste surface refuses actionably; an empty paste refuses rather than storing a blank credential; the consent warning precedes every unsupported-platform path.bun x tsc --noEmit- clean.Checklist
Security note: this adds a credential entry path. The pasted value is validated against the Model API before it is stored, never logged, and never echoed on any failure path - the existing "no failure path echoes the credential" test covers the new branches. The ToS consent warning is unchanged and still precedes every read.
CI status (updated after rebase). The stack was rebased onto current
dev: it branched whendevwas at 2.42.0, that version then shipped, andrelease version linecorrectly refused a tree claiming an already-published version. That failure was ours and is fixed.Two failures remain and are inherited, not introduced. Both were reproduced on clean
origin/devin a scratch worktree rather than assumed:tests/loopback-listener-integration.test.ts:366(image routes on the loopback listener, arrived with fix(server): allow image routes on loopback listener #3430) - 30 pass / 1 fail on cleandev, identical here.tests/star-deferral.test.ts:102- 6 pass / 1 fail on cleandev, identical here.Neither is in this stack's blast radius. Full triage:
devlog/_plan/260904_cross_platform_parity/041_ci_triage.md. This means the honest claim is no new failures, not "all checks pass" - the stack cannot go fully green untildevdoes.Summary by CodeRabbit
