Two points.
First, the allowlist is partly redundant.
strings.HasSuffix(host, ".kimi.com")already coversauth.kimi.comandapi.kimi.com, so only the barekimi.comcase needs a separate test. The suffix tests are correct as written; the leading dot prevents anotkimi.commatch.Second, the domain set looks inconsistent.

162-172: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winOne non-canonical override silently strips the headers from the canonical requests too.
providerExtraHeadersreturnsnilif any single supplied endpoint is non-canonical. Consider an operator who overrides onlyZERO_OAUTH_KIMI_CODE_TOKEN_URLto a proxy and leaves the device endpoint atauth.kimi.com. The device-authorization request then goes to the canonical Kimi host without theX-Msh-*headers. Per the comment at Lines 183-190, Kimi answers 401. The user sees an authorization failure with no indication that an override caused it.The fail-closed choice is right; do not send identity headers to an unapproved host. The problem is that the decision is all-or-nothing and invisible.
Two options, in order of preference:
- Decide per endpoint. Attach the headers to a request only when that request's own host is canonical. This keeps login working when only the token URL is proxied.
- If you keep the all-or-nothing rule, surface it. Emit a warning at login time that names the offending environment variable and states that vendor-identity headers are disabled.

lint-compatible test seam such as an unexported deviceIDPathOverride used by the
device-ID loading path. Update tests to drive isolation through that seam while
preserving production behavior and synchronization.
- Around line 194-216: Update createOrAdoptDeviceID’s successful os.Rename path

this helper in internal/oauth/providers_test.go at lines 90-101 and

There was a problem hiding this comment.
Thanks for the very thorough work here — the OAuth plumbing itself is in good shape and I checked the parts that usually go wrong on this path:
- Redirects are refused on all four credential-bearing POSTs (
RequestDeviceCode,pollDeviceOnce,PostToken, andRefreshviaPostToken), so the newExtraHeaderscan't ride a 307 to another origin. - I drove a throwaway
httptestTLS server through all four and confirmed theX-Msh-*values actually reach the wire — that part works. providerExtraHeadersfails closed when an endpoint is overridden off a canonical Kimi host, and resolving a retargetedkimi-codeprofile through the realconfig.Resolveentry point does drop the identity headers while keeping user-supplied ones.- The
kimialias still resolves tomoonshot,gofmt/go vetare clean, and./internal/{kimiidentity,oauth,providercatalog,config,tui}all pass (the onlyinternal/clifailure is the pre-existing symlink-privilege one).
That said, I'd like changes before this merges. The problems are all in the device-identity lifecycle, not the protocol work.
1. First-run onboarding mints the Kimi device id for every user. internal/tui/onboarding.go:117 — setupOAuthProviderOptions filters the provider list by calling providercatalog.Get(option.ID) on every option, and Get now runs RuntimeHeaders → kimiidentity.DeviceID(). That function is reached from setupMethodOptions (onboarding.go:541), which is called from the render path setupMethodLines (onboarding.go:1665) as well as advanceSetup (onboarding.go:827). So the "How do you want to connect?" screen creates <UserConfigDir>/zero/kimi-device-id on first paint, before anyone has picked a provider.
I proved it with a temp config root: after All() and OAuthProviders() the file does not exist, and after one setupOAuthProviderOptions call it does. That's the exact invariant cloneDescriptor's own comment claims to protect ("merely enumerating providers never mints ~/.config/zero/kimi-device-id for users who never touch Kimi"). The filter only needs descriptor.OAuth, which the listing descriptors already carry — use OAuthProviders()/All() here, or add a headers-free lookup. Please add a test that walks the method + provider screens and asserts the file was never created; right now nothing would catch this coming back.
2. The wizard bakes the hostname and device UUID into config.json, and the resolver ignores them anyway. internal/tui/provider_wizard.go:2145 copies the runtime headers into profile.CustomHeaders, and applyProviderWizard persists that profile through config.UpsertProvider. I upserted a wizard-built profile into a temp config and read it back:
"customHeaders": {
"X-Msh-Device-Id": "b5fd6ed8-50fb-4eec-8195-87571e6c8f60",
"X-Msh-Device-Model": "windows amd64",
"X-Msh-Device-Name": "Vasanth",
...
}
X-Msh-Device-Name is os.Hostname(). Two problems with persisting it. First, it's dead weight: applyCatalogDescriptor at internal/config/resolver.go:1074 deliberately skips stored x-msh-* values so the freshly minted ones win, so nothing ever reads the persisted copy. Second, it puts a machine hostname and a stable device UUID into a file people paste into bug reports, and the strip in resolver.go:1112 only fires while catalogId is present — resolving a profile with those headers, catalogId removed and baseURL: https://proxy.example.test/v1 forwards X-Msh-Device-Id and X-Msh-Device-Name to that host untouched. Note zero auth kimi (EnsureCatalogProvider) does not persist them, so the CLI and TUI already disagree. Simplest fix: keep the wizard's in-memory profile for the discovery call, but don't write RuntimeHeaders-derived headers to disk — the resolver re-attaches them at resolve time.
3. Both new guards in applyCatalogDescriptor are unproven. I removed the x-msh- prefix delete (resolver.go:1112-1116) and the stored-header override guard (resolver.go:1074-1076) and ran go test ./internal/config/ -count=1 — fully green. TestApplyCatalogDescriptorStripsKimiIdentityFromRetargetedProfile (resolver_test.go:1577) passes only because Require("kimi-code") returns a CustomHeaders map containing every X-Msh-* key, so the pre-existing EqualFold catalog-key loop already deletes both of the profile's headers. The only new code that test exercises is the widened else if condition. Please add: a case where the descriptor has RuntimeHeaders but empty CustomHeaders (the case the prefix branch exists for), and a case where a stale persisted X-Msh-Device-Id must lose to the freshly minted one on the canonical endpoint. Both should go red if the corresponding line is deleted.
4. Two existing tests were deleted rather than updated.
internal/providercatalog/catalog_test.go—TestListByTransportPreservesCatalogOrderis gone (it was at line 364 onmain), along with itsexport_test.gohelper. That test pinned per-transport catalog ordering and theTransportOpenAICompatible/TransportAnthropicCompatiblealias normalisation. Addingkimi-codeinto the openai-compatible run breaks itswantIDslist, so the fix was one line: add"kimi-code"after"chatgpt". Deleting the only ordering guard to make a new descriptor fit isn't a trade I want to make. (SwappingValidTransport/ValidAPIFormatfor inline maps inTestCatalogDescriptorsExposeRequiredDefaultsis fine — that keeps the per-descriptor invariant.)internal/oauth/providers_test.go—TestEnvKeywas replaced in place byTestResolveConfigKimiCodeStripsExtraHeadersOnEndpointOverride.envKeyis still production code and is exactly what mapskimi-code→ZERO_OAUTH_KIMI_CODE_*; put the old test back alongside the new one.
One thing that needs a decision, not a code change. internal/providercatalog/catalog.go:158 says the bearer is accepted directly "so no client spoofing is involved", while internal/kimiidentity/kimiidentity.go:30-37 says X-Msh-Platform must be kimi_code_cli because the coding/v1 endpoint runs a client whitelist. Those can't both be true, and the second one is the operative claim — we'd be presenting Zero as Moonshot's own CLI to get past an allowlist. That's an owner call and I'd like it made explicitly before this lands, same as we've done for other provider presets. Related: your own comments say the header names and values are reverse-engineered from kimi-cli and "should be confirmed against a real login before this ships" (and X-Msh-Version currently ships the literal string "unknown"). Has anyone run a real Kimi Code login end to end against this branch? If not, that's the last gate.
Smaller things, none blocking:
internal/oauth/presets.go:162-172: overriding one endpoint (say onlyZERO_OAUTH_KIMI_CODE_TOKEN_URL) drops the identity headers from all requests, including the ones still going toauth.kimi.com, which by your own comment means a 401 the user can't diagnose. Either decide per endpoint, or surface which env var disabled them.internal/oauth/presets.go:174-180: the allowlist takes.moonshot.cnbut not baremoonshot.cnand not.moonshot.ai, while the existingmoonshotdescriptor usesapi.moonshot.ai. Add a line saying that's deliberate or tighten the list.- No test asserts
ExtraHeadersreach the wire. I verified by hand that they do, but given the entire feature hinges on it, anhttptestserver recordingr.HeaderacrossRequestDeviceCode/pollDeviceOnce/PostToken/Refreshis worth having. internal/kimiidentity/kimiidentity.go:168: the 2s lock-staleness threshold is never refreshed while the holder works, so a stalled holder can have its lock broken mid-publish and the two racers can walk away with different ids than what's on disk. Narrow, and it needs an already-corrupt file to reach — but consider touching the lock mtime while working.docs/oauth-subscriptions.mddocuments theX-Msh-*requirement but not that one of those headers is the user's machine hostname. Worth saying out loud since it goes to a third party on every completion.
Happy to re-review as soon as 1-4 are addressed.
Everything in one pass as usual, nothing held back for a second round. The two deleted tests are the ones I'd push back on hardest — a guard removed to make a new descriptor fit is the kind of thing that's invisible in six months, and both look like one-line updates rather than deletions.

Approving. Re-checked on d41e06fd and all four are properly closed — I verified rather than read.
Onboarding no longer mints the device id. Filtering via OAuthProviders() listing clones instead of Get()/RuntimeHeaders is the right fix — it removes the call rather than guarding it, so there's no path left that reaches DeviceID() from a render.
The wizard no longer persists identity headers. stripRuntimeIdentityHeaders is genuinely pinned: I disabled it and TestStripRuntimeIdentityHeadersDropsXMshOnly goes red with the persist copy still carrying X-Msh-Device-Id, X-Msh-Device-Name and X-Msh-Platform — while correctly keeping X-User-Agent. That last part matters; a strip that took everything would have passed a weaker test.
Both deleted tests are back. TestListByTransportPreservesCatalogOrder returns with kimi-code added to its expected list, which was the one-line fix, and TestEnvKey sits alongside the new endpoint-override test rather than replacing it. Thanks for restoring them rather than arguing the point — the catalog-ordering guard is exactly the kind of thing nobody misses until it's needed.
internal/oauth, internal/providercatalog and internal/config all green here. The single internal/tui failure is TestAltScreenTranscriptScrollKeepsFooterFixed, which fails on origin/main for me too and passes in CI — a symlink/terminal quirk on my box, unrelated to this.

- Around line 606-612: Inspect newAuthManager to verify the AllowPresets value
used by auth login, then update the conflicting provider descriptions to match
that shipped behavior. In internal/cli/auth.go lines 606-612, correct the stale
Kimi or xAI help text; in docs/oauth-subscriptions.md lines 84-109, align both
the xAI opt-in and Kimi opt-out statements with the same result.
In `@internal/kimiidentity/kimiidentity.go`:
- Around line 164-175: The stale-lock recovery in the lock acquisition flow must
not reclaim locks solely based on the two-second mtime threshold. Update the
logic around os.ReadFile, os.Stat, and os.Rename to use a renewable lease or
another ownership protocol that proves the holder is dead before reclamation,
failing closed when ownership or permission cannot be verified; preserve atomic
lock replacement only after that proof.
- Around line 116-138: Update the device-ID publication flow around
readValidDeviceIDWithRetry and repairAbandonedDeviceID to write the complete ID
to a temporary file, check WriteString, Sync, and Close errors, then atomically
replace the destination while holding the repair lock. Apply the same atomic
publication and failure propagation to the initial creation path, returning an
error or otherwise signaling failure instead of an ID that was not persisted;
preserve post-publication rereading for race convergence.
- Around line 186-193: Update the deferred cleanup in the lock-acquisition flow
around lock.WriteString, lock.Sync, and lock.Close so failures from lock.Close
or removing lockPath are propagated to the caller or otherwise prevent a
successful device ID result. Only remove lockPath when its contents still match
ownerToken, preserving pre-existing or concurrently replaced locks, and ensure
cleanup failure causes the repair operation to fail closed.
- Around line 87-111: Update loadOrCreateDeviceIDAt and the helpers it invokes,
including readValidDeviceID and createOrAdoptDeviceID, to perform all device-ID,
lock, temporary-file, and rename operations relative to an opened
configuration-root handle using traversal-resistant, no-follow operations and
platform reparse-point protections. Remove direct path-based os.ReadFile,
os.MkdirAll, os.OpenFile, os.WriteFile, and os.Rename usage for these
operations; do not rely on pre-open EvalSymlinks, and preserve the existing
race-safe create-or-adopt behavior.
In `@internal/oauth/manager.go`:
- Around line 201-205: Update the token persistence flow around ProviderKey and
m.store.Save to serialize context cancellation with the commit, using an attempt
generation or shared lock so cancellation and token persistence are mutually
exclusive. Ensure a device-login attempt that is canceled before commit cannot
overwrite stored authentication state.
In `@internal/oauth/oauth.go`:
- Around line 117-126: Add request-level httptest regression coverage for
applyExtraHeaders across device authorization, device polling, code exchange,
and refresh flows. Assert Kimi ExtraHeaders are received by each HTTP handler,
and verify a provider without ExtraHeaders sends none; keep the existing
configuration-resolution tests intact.
In `@internal/oauth/presets.go`:
- Around line 174-180: Restrict isCanonicalKimiHost to an explicit allowlist of
approved OAuth endpoint hosts instead of accepting arbitrary *.kimi.com or
*.moonshot.cn subdomains. Preserve URL parsing and case normalization, then add
tests covering every approved host and representative unapproved subdomains to

16-33: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winThe test does not exercise the
WAIT_OBJECT_0branch it claims to cover.This was raised in a previous review and is still present.
cmd.Wait()releases the process handle thatcmd.Processholds. The_ = cmd.Processstatement at Line 29 is a no-op; it retains nothing. AfterWaitreturns, the PID can be freed, soprocessAlive(pid)returnsfalsethrough theERROR_INVALID_PARAMETERpath inOpenProcess, not throughWaitForSingleObjectreturningWAIT_OBJECT_0. The test therefore passes without proving that exit code 259 is handled correctly, and it can flake if the operating system recycles the PID onto a live process before the probe.Open a
SYNCHRONIZEhandle beforecmd.Wait(), keep it open across the assertion, and callcmd.Wait()after the assertion. The retained handle keeps the PID reserved and forces the wait path.💚 Proposed fix: retain a SYNCHRONIZE handle across the probe
pid := cmd.Process.Pid - err := cmd.Wait() + // Hold an independent handle so the PID cannot be freed or recycled while + // we probe; this forces the WaitForSingleObject path in processAlive. + handle, err := windows.OpenProcess(windows.SYNCHRONIZE, false, uint32(pid)) + if err != nil { + t.Fatalf("OpenProcess: %v", err) + } + defer windows.CloseHandle(handle) + + err = cmd.Wait() var ee *exec.ExitError if !errors.As(err, &ee) || ee.ExitCode() != 259 { t.Fatalf("Wait: %v (want ExitError with code 259)", err) } - // Keep a live reference so the process object is still openable by PID - // while we probe (Go retains a handle until Process is released). - _ = cmd.Process if processAlive(pid) { t.Fatalf("processAlive(%d) = true after exit code 259; want false (dead)", pid) }Add the import:

157-196: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winThe adopt-the-winner test depends on a fixed timing margin.
The simulated winner sleeps 30ms before writing.
readValidDeviceIDWithRetrygives up after 200ms. That leaves 170ms of slack.

deferinside the retry loop stacks cleanups across iterations.Lines 184 and 202 register deferred cleanups inside the
forloop. Each loop iteration that reaches the holder branch adds more. In practice the holder branch always returns, so only one set runs today. That safety depends on every return statement staying in place.Move the cleanup into a helper function that owns the lock lifetime, or convert the holder branch into a separate function. This removes the dependency on the return placement.

In `@docs/oauth-subscriptions.md`:
- Line 40: Update the documented “Sign in with OAuth” chooser text to match the
shipped providerWizardMethodOptions subtitle, including “one-click” and the
correct provider lists; preserve the transcript’s existing formatting.
- Around line 54-71: Resolve the OAuth preset documentation contradiction by
making the ChatGPT and Hugging Face bullets consistent with the current preset
behavior described near the onboarding and login instructions. Update the stale
“opt-in preset” and ZERO_OAUTH_ALLOW_PRESETS wording in those provider sections,
or narrow the broader claim if those providers still require opt-in on the
stated paths; ensure all descriptions match shipped behavior.
In `@internal/cli/provider_setup_test.go`:
- Around line 73-104: Both Kimi CLI tests use the real device-ID storage
location. In internal/cli/provider_setup_test.go lines 73-104 and 106-125, add
an isolateKimiDeviceIDStorage(t) helper that redirects XDG_CONFIG_HOME, APPDATA,
and HOME to t.TempDir(), then call it as the first statement of
TestProvidersAddKimiCodeDoesNotPersistRuntimeHeaders and
TestSetupKimiCodeDoesNotPersistRuntimeHeaders.
In `@internal/kimiidentity/kimiidentity_test.go`:
- Around line 285-287: Update the test around the divergence-repair scenario to
assert token convergence and persistence rather than requiring the lock file to
be absent, since cleanup is best effort after reclaim. Move the lock-absence
assertion to the single-holder test near the existing deterministic outcome,
preserving the current cleanup check there.
In `@internal/kimiidentity/kimiidentity.go`:
- Around line 247-252: The deadline fallback in DeviceID must not return an
unpersisted locally generated id: update the timeout paths around
readValidDeviceIDWithRetry so the fallback ID is successfully persisted before
returning, or otherwise ensure the returned and persisted identities cannot
diverge. Apply the same fix to the analogous fallback branches referenced near
the other timeout checks, preserving existing retry behavior.
- Around line 163-172: Update the lock acquisition in
internal/kimiidentity/kimiidentity.go:163-172 around root.OpenFile and
lock.WriteString to stage the owner token in a private temporary file, then
claim lockName atomically with a no-replace link so any visible lock is
immediately parseable; preserve the existing cleanup and convergence behavior.
In internal/kimiidentity/kimiidentity_test.go:238-288, keep the convergence
assertion unchanged and run the test under -race.
In `@internal/lockutil/reclaim.go`:
- Around line 153-160: Update restoreRootedLock in internal/lockutil/reclaim.go
at lines 153-160 to restore the sidelined file without reading its contents:
claim the available lockName using an O_EXCL probe, then rename the sidelined
file back. In internal/lockutil/reclaim_test.go at lines 144-196, add a
link-operation seam and tests covering link failure with both readable and
unreadable lock contents.
In `@internal/oauth/manager.go`:
- Around line 43-47: The device-token transaction in CompleteDeviceLogin must be
serialized across Manager instances and processes, not by the per-Manager
deviceCommitMu. Coordinate by credential-store path and hold the store-scoped
lock across snapshot, Save, cancellation check, and rollback; abort before Save
when snapshot reading fails, propagate rollback errors, and do not report
success when cleanup or unlock fails. Add a regression test using two managers
sharing one store.

P1 — Do not publish a device ID while a live lock holder owns the lease.
Remove the unlocked deadline publication. After the deadline, return a valid existing ID only. Otherwise, keep waiting for the live holder or return an error through an error-capable API. Add a regression test that holds a live lease for longer than The runtime-header helper, test environment isolation, rooted restore fallback, and store-scoped token commit changes look consistent with their stated intent. The new two-manager OAuth test is sequential, so it does not validate contention, but the ✅ Action performedFull review finished. |

TestLoadOrCreateDeviceIDWaitsForSlowLiveRepairLockHolder and
publishOrAdoptDeviceID by keeping the live owner token present beyond the
5-second maxWait deadline, then assert the caller’s fallback does not overwrite

- Around line 198-229: Update both fallback tests,
TestReclaimStaleLockRootedFallbackWhenLinkFails and the neighboring fallback
test, to register root.Close through t.Cleanup and report any close error with
t.Errorf. After validating the restored lock contents, inspect the temporary
directory and fail unless only the restored lock remains, ensuring no .stale.*
sidelined file is leaked.
In `@internal/lockutil/reclaim.go`:
- Around line 161-169: The hard-link fallback in the reclaim flow currently
exposes an empty lock between the O_EXCL probe and Rename, allowing
lockHolderAlive to classify a live lock as abandoned. Update the fallback around
ReclaimStaleLockRooted to ensure lockName is never observable as empty—prefer
populating the probe from reclaimed before replacement, while preserving the
existing probe-and-rename fallback when reading fails; retain atomic replacement
and race protection.
In `@internal/oauth/manager_test.go`:
- Around line 339-341: Update the test setup around the seed Token and
m.store.Save call to check and fail on the returned error immediately, so setup
failures are reported directly before assertions about the restored token run.
- Around line 370-406: Update TestCompleteDeviceLoginTwoManagersSharingStore to
create two independent Store values with the same FilePath, then run both
managers’ CompleteDeviceLogin calls concurrently using distinct token responses.
After both commits complete, load through the second store, assert the surviving
token matches either committed token, and verify the token file parses
successfully; keep the test suitable for execution under the race detector.
In `@internal/oauth/presets.go`:
- Around line 203-204: Update publishOrAdoptDeviceID to avoid writing or
renaming a candidate ID after the deadline when lockHolderAlive is true; only
the confirmed lock owner may publish, otherwise fail closed and preserve the
live holder’s ID. Add a regression test covering a live holder that exceeds the

ID.

I found issues that need to be addressed before this is ready.
Overall guidance
This needs a reset to a current, small, testable change rather than another
round of targeted fixes on this branch. The current PR has accumulated dozens
of follow-up commits on an obsolete base, and its base-to-head diff now mixes
the intended Kimi integration with rollbacks of unrelated features and prior
security fixes. That makes individual review fixes misleading: a local change
can make one test pass while the submitted branch still deletes a contract that
was added later on main.
Please start by rebasing the work onto current main (or reconstructing it as
a fresh branch from current main) and verify that the resulting diff contains
only the deliberate Kimi feature and its focused tests/docs. Treat that as a
new integration, not as a mechanical conflict-resolution exercise: preserve
the current implementations for token storage, updater staging/recovery,
planning permissions, messaging, and every unrelated subsystem. Split any
unrelated cleanup out of the Kimi PR.
Then design the Kimi integration around explicit ownership boundaries before
adding more retry logic:
- Device identity persistence must have a defined result for each state:
existing valid ID, another active publisher, a proven-dead publisher,
unreadable/unwritable storage, cancellation, and process interruption. A
retry loop is only correct for a bounded, observable contention state; it
must not turn local I/O errors or ambiguous liveness into an indefinite
foreground hang. - Resolve the final OAuth endpoints before deriving identity headers or making
a request. Environment overrides should produce either one coherent endpoint
configuration or a clear validation error—never a hybrid of override-derived
header policy and preset-derived network destinations. - Treat OAuth tokens as credentials when applying project configuration. A
project file must not gain authority to route any inherited credential,
whether it originates in an environment variable, a config field, a keyring,
or the OAuth store. - The Kimi device identity and
X-Msh-*headers are reverse-engineered vendor
behavior. Keep their generation lazy, avoid persisting host/device data where
it is not required, document exactly which information is sent, and validate
the complete device-code, refresh, and completion sequence against a real
approved integration account before relying on it.
For the replacement PR, favor a concise behavior matrix and deterministic
tests over timing-based retry tests. Cover concurrent first use and repair,
failed writes, stale locks/PID reuse, cancellation at every OAuth transition,
canonical and overridden endpoints, config persistence, project-config
overrides, and token/header routing. Run those focused tests together with the
current required platform/security checks after the rebase. This will let
review focus on the provider contract itself instead of rediscovering branch
drift or one more race in each author round.
Findings

[P0] Rebase this branch before merging
This branch forks from097c2652, while the PR targets currentmainatdc15e822; the resulting base-to-head diff removes 38,296 lines in 342 files. The removals include the peer-message service, terminal-pet support, the CLI's--plan/--permission-mode planread-only execution mode, and the hardened update staging/recovery implementation. They are deletions rather than renames, and none are in the Kimi OAuth scope described by the PR. For example,main's security update #751 added descriptor-bound, unpredictable executable staging precisely to prevent post-verification substitution, but this branch brings back fixed-path staging.Please rebase the Kimi commits onto current
mainand resolve conflicts by preserving the target branch's behavior and tests. Do not selectively restore individual files from this review: the root cause is that the entire feature stack was developed against an obsolete snapshot, so the resulting rebased diff must be reviewed again as a narrow Kimi-only change. -
[P1] Make Kimi identity acquisition fail instead of spinning forever
internal/kimiidentity/kimiidentity.go:207
A persistent write failure after the config directory has opened (for example a read-onlyzero/directory, full disk, or quota exhaustion) makespublishDeviceIDAsHolderreturn false before a lock exists.publishOrAdoptDeviceIDthen callsReadFileon the nonexistent lock, gets no successful reclaim, sleeps for 10 ms, and repeats forever. Separately, repair locks encode<pid>.<timestamp>butlockHolderAlivediscards the timestamp and checks onlyprocessAlive(pid): once a crashed holder's PID is reused, an unrelated process keeps the lock unreclaimable and reaches the same unbounded loop.DeviceIDholds the package mutex and is invoked while constructing Kimi OAuth/runtime headers, so this freezeszero auth kimi, onboarding, refresh, and Kimi requests before they can return a usable error. Define a finite acquisition protocol: distinguish contention from local I/O failures, use a process-local fallback or return a clear persistence error when durable storage cannot be written, and make a repair lease identify the original process (or expire under a conservative, testable policy) rather than PID liveness alone. Add deterministic tests for an unwritable-but-readable directory and a stale lock whose PID is live but does not belong to the original holder. -
[P1] Apply the Kimi issuer override to the endpoints actually used
internal/oauth/providers.go:72
The documentation advertisesZERO_OAUTH_KIMI_CODE_ISSUER_URLas an OAuth-host override, butResolveConfigoverlays it onto the preset without clearing the preset device/token endpoints.Manager.resolveEndpointstherefore returns immediately because all endpoints are already nonempty, and the device authorization and token requests still go tohttps://auth.kimi.com. At the same timeproviderExtraHeadersexamines the raw non-canonical issuer override, returns noX-Msh-*headers, and makes those unchanged Kimi requests fail because their required identity headers were removed.Resolve endpoint selection first, then calculate provider headers from the concrete URLs each request will use. An issuer override should either clear the preset endpoints and use discovery, or be rejected when combined with pinned preset endpoints; it must not silently produce a hybrid configuration. Cover the documented issuer-only configuration and verify both the requested URLs and header set, including canonical and non-canonical override hosts.
-
[P1] Do not send a stored Kimi bearer to a project-selected endpoint
internal/config/resolver.go:368
The project-provider merge guard protects inherited API-key/header credentials but ignores OAuth credentials stored separately. A user can runzero auth kimi, creating a token underprovider:kimi-code, then open a project whose config merges a keyless profile of that name withbaseURL: "https://attacker.example/...". The merged profile still hasCatalogID: "kimi-code";OAuthLoginCandidatesselects that stored token andoauthLoginForProfileattaches it as a Bearer credential to the project-selected URL. StrippingX-Msh-*headers on retargeting does not protect the more sensitive OAuth token.Keep endpoint authority and credential authority coupled. Before a project layer may change a profile endpoint, determine whether the merged profile can resolve any stored OAuth login as well as inherited API-key/header material; reject the override unless it remains an explicitly allowed catalog endpoint. Add a regression test that seeds a Kimi login, applies a project
baseURLoverride, and proves the configuration is rejected before a provider can be built. -
[P2] Link the required approved parent issue
This PR is from aCONTRIBUTORand has no linked issue or approved case in its current metadata.AGENTS.mdrequires community pull requests to have a parent issue carrying theissue-approvedlabel; the contributor association is not one of the policy's maintainer exemptions. Please link the approved issue before this is merged so maintainers can confirm the requested provider integration, third-party client identity, and reverse-engineered vendor headers have been approved at the intended scope.
The previous branch forked from an obsolete snapshot and its base-to-head diff deleted unrelated mainline work. Replay only the Kimi feature so token storage, updater staging, planning, and messaging stay intact.
…g endpoints. Identity acquisition now has a bounded result for contention, dead or expired leases, unwritable storage, and cancellation instead of looping forever. Endpoint overrides resolve to one coherent destination before X-Msh headers are derived, and a project file cannot retarget a stored Kimi bearer.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
The OAuth lookup can still block config resolution with no timeout.
lookupStoredOAuthLogin builds a store from oauth.NewStore and calls store.Load for each candidate name. With ZERO_OAUTH_STORAGE=keyring, NewStore selects keyringBlob, which reaches the OS keychain through an external process and serializes through a cross-process lockfile. Load therefore performs a blocking external call on the Resolve path, and no deadline bounds it. A slow, locked, or prompting keychain stalls zero startup for any project whose .zero/config.json sets a provider baseURL or apiKeyEnv.
The Env threading and the fail-closed error handling are correct now. Add a bound to the call so a wedged keychain degrades to the fail-closed path instead of hanging.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
The non-Link fallback still exposes an empty lock file.
root.OpenFile with O_CREATE|O_EXCL creates lockName before WriteString publishes the owner token. A concurrent caller that reads lockName inside that window sees empty contents. lockHolderAlive at Line 330 classifies empty contents as dead, so reclaimDeadRepairLock can remove a lock this process holds, and the two callers can then publish different UUIDs.
The primary root.Link path is atomic and closes this window, so the exposure is limited to filesystems without hard links. The same tmp-then-link staging can be reused here: retry Link once, and treat a persistent link failure as publishPersistFailed instead of creating a visible empty lock.

Do not mint a device ID when no endpoint is configured.
providerExtraHeaders returns kimiExtraHeaders() when every endpoint is empty. ResolveConfig calls this function before it rejects incomplete Kimi configuration. kimiidentity.Headers() then creates and persists X-Msh-Device-Id.
Require at least one non-empty canonical endpoint before calling kimiExtraHeaders. Add a regression test that incomplete Kimi configuration returns an error without creating the device-ID file.
As per coding guidelines, “Every behavior or security-boundary change requires a regression test, including failure paths.”

I found issues that need to be addressed before this is ready.
Findings
-
[P1] Do not expose an empty lock on the no-hard-link path
internal/kimiidentity/kimiidentity.go:177
The hard-link path is safe because it first writes and syncstmpLockName, then makes that complete inode visible aslockName. The fallback reverses that property:OpenFile(...O_EXCL)exposes a zero-bytelockNamebeforeWriteStringandSyncrun. A second first-use process can read that file during the gap;lockHolderAlivetreats its empty/unparseable contents as dead,ReclaimStaleLockRootedmoves/removes it, and the second process becomes a publisher while the first still owns an open descriptor for the old inode. Both can then publish different IDs, with the later rename determining persistence while each process caches/uses its own value. The root cause is using visibility of the lock name as acquisition before its ownership proof is durable. Preserve the complete-record-before-publication invariant in the fallback too (or make incomplete records fail closed), and add a deterministic no-hard-link contention test that pauses immediately after exclusive create. -
[P1] Do not reclaim a confirmed-live publisher merely because its lease age elapsed
internal/kimiidentity/kimiidentity.go:325
lockHolderAlivereturns false once the timestamp is older thandeviceIDLeaseTTL, before consulting whether the PID is still alive. If a legitimate holder is descheduled or blocked inwriteDeviceIDFile/beforeRenameHookfor more than ten seconds, the next caller reclaims its lock and publishes ID B. The original holder is never fenced: when it resumes, it still executesRename(tmpName, name)and overwrites B with ID A. The callers therefore use divergentX-Msh-Device-Idvalues and the durable identity flips underneath them. The root cause is treating a one-shot timestamp as proof that an otherwise-confirmed live owner has lost its right to commit, without a renewal mechanism or a commit-time ownership check. Use a renewable/fenced lease or an OS lock held through publication; at minimum, never reclaim solely on age while the owner is confirmed alive, and test a pause longer than the TTL at the pre-rename seam. -
[P2] Avoid repeating bounded keyring calls while resolving project config
internal/config/resolver.go:462
This new project-merge guard callsStore.Loadonce for every value fromOAuthLoginCandidates. WithZERO_OAUTH_STORAGE=keyring, each load synchronously launchessecurity/secret-tool; the command has a 10-second timeout, but a renamed keyless profile commonly has both its profile name and catalog ID as candidates. A locked or unavailable keyring therefore makes startup wait 10–20 seconds for each affected project profile before the intended fail-closed path is reached. The root cause is putting repeated interactive/external credential I/O inside a pure-looking per-profile merge predicate, with no merge-wide deadline or memoization. Resolve each distinct OAuth key at most once under a small shared budget (or avoid keyring reads during project merge), cache both misses and errors, and continue to treat timeout/error as credential material present so the endpoint-retargeting guard remains fail closed. -
[P2] Do not mint a Kimi identity for an invalid configuration
internal/oauth/presets.go:170
providerExtraHeadersaccepts an all-empty endpoint slice because its loop only rejects non-empty noncanonical values.ResolveConfigcallsattachProviderHeadersbefore it checks the required client ID/endpoints, so a probe such asResolveConfig("kimi-code", nil)reacheskimiExtraHeaders→DeviceID, creates~/.config/zero/kimi-device-id, and only then returns the configuration error. No Kimi request can occur. The root cause is performing the identity-producing side effect while constructing an unvalidated config, rather than at a validated request boundary. Require at least one resolved canonical destination and attach headers only after configuration validation succeeds; add a regression asserting that failed resolution leaves the redirected config directory untouched. -
[P2] Route the Kimi Ctrl+O path through the visible device-code flow
internal/tui/provider_wizard.go:1025
Kimi can be selected through the ordinary browse/API-key credential step. Ctrl+O there unconditionally callsbeginOAuthAttempt(false)andproviderWizardOAuthCmdFor; despite thefalseflag, Kimi'sFlowDevicepreset makesManager.LoginrunloginDevice. That method writes the verification URL and user code toManager.Out, which defaults toio.DiscardinrunProviderTokenLogin, while the wizard renders a browser-login spinner. The user never receives a code and the login eventually times out. The root cause is having a second OAuth entry point that bypasses theOAuthDeviceOnlyrouting already added to the provider-list Enter/mouse paths. Route this path throughstartProviderDeviceLoginfor device-only descriptors, render a device-code-specific instruction, and test Ctrl+O from the credential step on a desktop-shaped environment. -
[P3] Describe Kimi's device-only login accurately in the provider picker
internal/tui/provider_wizard.go:1863
OAuthDeviceOnlyis a stricter subset ofOAuthDeviceFlow, but the broad test runs first, so Kimi is rendered as “browser or device code” even though it has no browser authorization endpoint. This is the same classification-order error that made device-only routing easy to miss elsewhere. CheckOAuthDeviceOnlybeforeOAuthDeviceFlow, display “device code”, and keep the picker, footer, credential hint, and docs derived from one flow-description helper so future UI paths cannot disagree.
Before the next review
These are not six unrelated edge cases. They point to three missing boundaries in the feature, so please address the underlying design rather than applying six narrow patches:
-
Define one device-ID publication protocol. The ID file and lock file form a small cross-process transaction: acquire a durable owner record, publish exactly one completed ID, let every contender either adopt that ID or receive an explicit failure, and release only the owner’s lock. Every acquisition implementation—including filesystems without hard links—must provide the same atomicity. A timestamp is not a fencing token: a stalled but live holder must not lose commit authority merely because time elapsed. Decide whether the implementation can provide a renewable lease, a platform lock, or an error path when it cannot safely make progress; then make the final rename conditional on the holder still owning that authority. Do not rely on process-local fallback values to paper over a violated publication protocol.
Please build deterministic tests around the existing seams rather than timing-sensitive sleeps: force the no-hard-link fallback, pause after exclusive creation before the owner record is durable, pause a live holder beyond the lease interval before rename, and run at least two independent processes/roots through first use. Each case should assert both returned IDs and the final file contents converge, and should fail if a non-owner can rename or delete the lock.
-
Make side effects occur only at the appropriate lifecycle boundary. Resolving a provider configuration should validate and describe configuration; it should not create device identity state or perform repeated interactive keyring work merely because a caller is checking whether an endpoint override is allowed. Separate pure resolution/validation from the later operation that actually needs credentials or Kimi headers. Where credential presence is required for a security guard, give the lookup a small explicit shared budget, memoize it for the whole resolution, and fail closed on every unavailable/error/timeout path. Tests should cover invalid config, absent keyring, locked/slow keyring, multiple profiles, and prove the security guard remains closed without making startup scale with the number of profiles or aliases.
-
Use the provider flow capability as the single source of truth for all UI entry points. Kimi’s device-only capability is currently handled in the OAuth picker but bypassed from the credential shortcut, then described differently by the badge and hint. Centralize the decision into a helper that returns both the required flow and the user-facing description. Route keyboard, mouse, onboarding, browse/API-key credential steps, CLI aliases, and headless defaults through it. The test matrix should exercise every entry point for browser-only, browser-or-device, and device-only providers, including a desktop environment for the Kimi cases so headless auto-selection cannot mask a wrong branch.
After that design pass, please rebase onto current main, run the focused race tests plus the relevant TUI/config package tests, and include the exact commands/results in the PR description. That will make the next review about verifying one coherent protocol and flow model rather than uncovering another path around a local fix.
