Surface the discarded macOS Keychain grant and add a keyring escape hatch (Fixes #3020)

[acoliver]

TLDR

macOS Keychain items written by LLxprt carry an ACL whose change_acl owner entry has an empty trusted-application list. When the runtime's code identity changes, the user is prompted for their login password on every credential read, clicking Always Allow appears to work, and nothing is persisted — with no error surfaced to the user or to SecureStore. That silence is the defect this PR closes.

Two things land:

1. The recurring prompt is no longer silent. A new dependency-leaf module in packages/storage observes successful OS-keyring reads. When the same credential is authorized interactively a second time — in a read that began after the earlier authorization had already completed — the process enters a terminal state and writes exactly one actionable notice to stderr. Credential access is never blocked; the read that triggers the notice still returns its value.
2. There is a supported way out. LLXPRT_DISABLE_OS_KEYRING=1 makes createDefaultKeyringAdapter() return null before the native module is even imported, routing SecureStore credentials to the existing encrypted-file fallback. Existing Keychain items are left in place — nothing is deleted and nothing is migrated.

What reviewers should look at most closely:

• The detector is a heuristic, and the code says so. Wall-clock duration of a successful read is the only in-process signal that distinguishes "authorized without interaction" from "a human was asked to authorize this". It is not proof, and neither the module docblock nor the user-facing message claims otherwise.
• The root cause is deliberately under-claimed. See "Dive Deeper" — the source chain is fully established, the securityd mechanism is not, and the plan and docs say which is which.
• The escape hatch has real limitations, all four documented in docs/troubleshooting.md rather than papered over.

Dive Deeper

Root cause: what the source establishes

The write path was traced end to end, reading each layer rather than inferring:

Layer	Version	Call
default-keyring-adapter.ts	—	new AsyncEntry(service, account).setPassword(value)
@napi-rs/keyring	1.3.0	binding over keyring-core
apple-native-keyring-store (keychain)	1.0.1	Cred::set_secret
security-framework (os::macos::passwords)	3.7.0	SecKeychain::set_generic_password -> add_generic_password
macOS Security.framework	OS	SecKeychainAddGenericPassword

SecKeychainAddGenericPassword takes no SecAccess parameter, so the item's ACL is whatever macOS synthesizes by default. That default carries the required owner entry authorizing change_acl with an empty trusted-application list, which per Apple's SecACLCreateWithSimpleContents documentation means no application is trusted to amend the ACL without user confirmation — as distinct from a null list, which means any application may.

The load-bearing, fully-proven finding is the last one: no layer of that chain exposes any way to supply a different SecAccess. security-framework hardcodes SecKeychainAddGenericPassword in add_generic_password and offers no kSecAttrAccess pass-through; apple-native-keyring-store's only configuration key is which keychain domain to use; @napi-rs/keyring's surface is getPassword / setPassword / deleteCredential with no access-control API at all. The ACL therefore cannot be constructed or repaired from TypeScript, which closes out investigation items 2 and 3 in the issue: we cannot choose the SecAccess, and we cannot choose whether securityd stores an identity requirement or a cdhash.

What is deliberately NOT claimed: that the empty change_acl list is the proven mechanism by which the grant is discarded. Apple documents that empty owner list as requiring user confirmation, not as making the change impossible. Establishing the actual securityd behaviour would require native ACL inspection of an item immediately before and after a grant, which this change does not do. project-plans/issue3020/PLAN.md section 1, the module docblock, and docs/troubleshooting.md all state this explicitly rather than papering over it.

The detector

packages/storage/src/secure-store/keychain-grant-persistence.ts is a dependency leaf modelled on the existing runtime-replaced-errors.ts / runtime-identity.ts conventions: process-wide terminal state, a once-per-process stderr notice with the same EPIPE-safe write, and an injectable platform seam so the darwin-only behaviour is exercisable on every CI platform.

default-keyring-adapter.ts times the native read with performance.now() (monotonic — Date.now() can manufacture or erase a gap across an NTP step or sleep/wake) and records an observation only when the read returned a value. Absence and failure are not granted authorizations, and a rejection propagates untouched because the await throws before the record call.

An event is counted only when all of these hold:

• the platform is darwin;
• the duration is strictly greater than INTERACTIVE_AUTH_THRESHOLD_MS (1500);
• it is the second interactive read of the same credential, correlated by an opaque service\0account map key;
• that second read began at or after the first one completed — overlapping/concurrent first reads prove nothing, because neither could have benefited from the other's grant.

The correlation map is bounded at 256 entries and cleared when full; clearing at worst loses a first observation, which biases toward not warning — the safe direction. It is also cleared once the terminal state is reached, since it is no longer needed.

Requiring the same credential twice, non-overlapping, is what rules out the obvious false positives: two different credentials each prompting once, the isKeychainAvailable() probe (which uses a random account and so can never accumulate), and concurrent in-flight reads at startup. What it does not rule out is a pathologically slow but non-interactive keychain. The blast radius of a false positive is bounded to one stderr line and a boolean: nothing throws, nothing is stored differently, and the credential is still returned.

The escape hatch, and its limits

LLXPRT_DISABLE_OS_KEYRING=1 is checked in createDefaultKeyringAdapter() before the dynamic import. Every keyring consumer — SecureStore, machine-secret, and MCP KeychainTokenStorage — obtains its adapter from that one factory, so a single check covers all of them. Only the exact string 1 opts out, matching the existing LLXPRT_TEST_DISABLE_OS_KEYRING convention (which is kept separate and untouched: it exists for suite isolation).

Four limitations were verified in source and are documented rather than hidden:

• MCP server OAuth is not covered. MCPOAuthTokenStorage defaults to KeychainTokenStorage, which throws Keychain is not available when the factory returns null. This is the same pre-existing limitation that already applies on hosts with no keyring at all (headless Linux, containers). Fixing MCP's storage selection is out of scope here.
• fallbackPolicy: 'deny' still fails, by design — the opt-out must not silently defeat a deny policy. There is a test for this.
• The machine secret can change. When it lives only in the Keychain, disabling the keyring makes machine-secret resolution fall through to the file path and generate a different secret, so existing v:2 fallback files fail to decrypt with a loud CORRUPT error. Hence the guidance to set the variable persistently rather than toggling it per-invocation.
• Re-enabling reads the Keychain first, so a credential re-authenticated while opted out is silently shadowed by the older Keychain value. This one is silent, which is the other reason to treat the variable as persistent.

This is explicitly the interim escape hatch. The full settings-driven opt-out with reconciliation remains #2928's design problem; this PR does not attempt it.

Deliberately out of scope

Constructing a custom SecAccess; vendoring, patching or replacing @napi-rs/keyring / apple-native-keyring-store / security-framework; the rest of #2928 (native OSStatus fidelity, setter fallthrough, session-level degrade, settings-file opt-out); migrating existing Keychain credentials into the fallback store; and any change to the #3021 launcher warning, verifyKeyringWrite (#2927), or verifyKeyringDelete (#3011).

Review history

Reviewed by DeepThinker and by Open Code Review. Every finding was triaged. Fixed: the over-claimed root cause (rewritten in all three places), the uncorrelated process-global counter (now keyed by credential and non-overlapping), the non-monotonic clock, opt-out cases that had been added to a Vitest suite that is not in the Bun manifest (moved to a registered bun:test file, the Vitest file restored byte-identical to HEAD), the four false promises in the docs, and a test that claimed to cover the empty-string env value but actually deleted the variable. Rejected with reasons: removing the detector outright (no other in-process observable exists), a macOS-native ACL integration fixture (not runnable in CI), and narrowing the stderr catch (it intentionally mirrors emitRuntimeReplacedWarning — losing a notice is acceptable, breaking the credential read that triggered it is not). Deferred to #2928: a reconciling opt-out design.

Reviewer Test Plan

Automated — 18 behavioral cases, Bun + bun:test, both files registered in scripts/bun-test-manifest-data-storage.ts:

cd packages/storage
bun test --preload test-setup-storage-isolation.ts \
  ./test-bun/keychain-grant-persistence.bun.ts \
  ./test-bun/keyring-opt-out.bun.ts

Cases 1-9 drive the leaf module directly (single slow read is a non-event; two sequential slow reads warn once; further reads never re-warn; exactly-at-threshold never counts; fast reads never count; non-darwin never observes; different credentials never combine; overlapping reads never count). Cases 10-14 drive the real createDefaultKeyringAdapter() against a fake @napi-rs/keyring whose read duration and return value are independently controllable, plus the SecureStore surface. Cases 15-18 cover the opt-out, including the deny-policy boundary.

The adapter cases advance a controllable performance.now offset rather than sleeping, so the suite is deterministic and fast; the real function is restored in afterEach.

Manual, on macOS — recovery path:

export LLXPRT_DISABLE_OS_KEYRING=1
llxprt   # re-authenticate once
ls ~/Library/Application\ Support/llxprt-code/secure-store/   # .enc files appear
security find-generic-password -s llxprt-code-oauth           # Keychain item still present

Confirm the credential round-trips, the .enc ciphertext does not contain the plaintext, and no Keychain item was deleted. Then confirm only 1 opts out: LLXPRT_DISABLE_OS_KEYRING=0 (and '', and unset) must still use the Keychain.

Manual — the diagnostic itself requires a machine that actually reproduces the prompt storm (an ad-hoc-signed Bun on PATH, per #3021). On such a machine, two prompted reads of the same credential should produce exactly one stderr notice naming both remedies, and credential access should keep working.

Testing Matrix

	🍏	🪟	🐧
npm run	✅	❓	❓
npx	❓	❓	❓
Docker	❓	❓	❓
Podman	❓	-	-
Seatbelt	❓	-	-

Verified locally on macOS: npm run test (storage 36/36 isolated Bun files, 0 failures), npm run lint, npm run lint:eslint-guard, npm run typecheck, npm run format, npm run build, and the stepfun-37 smoke test — all exit 0.

The detector is darwin-gated in production but its behaviour is fully exercised on Linux and Windows CI through the injectable platform seam, so the new suites are not macOS-only.

Two unrelated local failures were investigated rather than waved away. packages/test-utils/src/interactive-run.test.ts fails identically (10 pass / 1 fail) on a clean origin/main checkout — pre-existing. The remaining failures were timeouts whose failing set differed completely between two runs of the same commit and which pass in isolation; none of them import anything this PR touches, and the storage workspace was green in every run.

This plan documents what the source establishes, stops short of\n+asserting the unproven securityd discard mechanism, and breaks the silence.\n+\n+## 1. Root cause, confirmed in source\n+\n+The issue asked for the empty change_acl application list to be confirmed\n+against source rather than inferred from behaviour. It has been. The write path\n+is fully traced below; every link was read, not assumed.\n+\n+### 1.1 The call chain\n+\n+| Layer | Version | Code |\n+| --- | --- | --- |\n+| packages/storage/src/secure-store/default-keyring-adapter.ts | — | new kr.AsyncEntry(service, account).setPassword(value) |\n+| @napi-rs/keyring | 1.3.0 | binding over keyring-core |\n+| apple-native-keyring-store (keychain module) | 1.0.1 | Cred::set_secret |\n+| security-framework (os::macos::passwords) | 3.7.0 | SecKeychain::set_generic_password → add_generic_password |\n+| macOS Security.framework | OS | SecKeychainAddGenericPassword |\n+\n+apple_native_keyring_store::keychain::Cred::set_secret:\n+\n+ fn set_secret(&self, secret: &[u8]) -> Result<()> {\n+ self.get_keychain()?\n+ .set_generic_password(&self.service, &self.account, secret)\n+ .map_err(decode_error)?;\n+ Ok(())\n+ }\n+\n+security_framework::os::macos::passwords, SecKeychain::set_generic_password\n+and add_generic_password:\n+\n+ pub fn set_generic_password(&self, service: &str, account: &str, password: &[u8]) -> Result<()> {\n+ match self.find_generic_password(service, account) {\n+ Ok((_, mut item)) => item.set_password(password),\n+ _ => self.add_generic_password(service, account, password),\n+ }\n+ }\n+\n+ pub fn add_generic_password(&self, service: &str, account: &str, password: &[u8]) -> Result<()> {\n+ unsafe {\n+ cvt(SecKeychainAddGenericPassword(\n+ self.as_CFTypeRef() as mut _,\n+ service.len() as u32, service.as_ptr().cast(),\n+ account.len() as u32, account.as_ptr().cast(),\n+ password.len() as u32, password.as_ptr().cast(),\n+ ptr::null_mut(),\n+ ))?;\n+ }\n+ Ok(())\n+ }\n+\n+### 1.2 The finding\n+\n+SecKeychainAddGenericPassword has no SecAccess parameter. Apple's own\n+documentation for it states: "This function sets the initial access rights for\n+the new keychain item so that the application creating the item is given trusted\n+access." The SecAccess is synthesised by macOS, and the synthesised access is\n+the standard default: one ACL entry authorising the data operations\n+(decrypt, derive, export_clear, export_wrapped, mac, sign) with the\n+creating application in its trusted-application list, plus the single required\n+owner entry authorising change_acl with an empty trusted-application\n+list.\n+\n+An empty list is not the same as a null list. Apple's\n+SecACLCreateWithSimpleContents documentation is explicit: "Set this parameter\n+to nil to indicate that any app can use this item. Pass an empty array to\n+indicate that there are no trusted apps." The applications (0) form observed\n+in the issue's security dump-keychain -a output is therefore the "no trusted\n+apps" form: no application is trusted to amend the ACL without user\n+confirmation (as distinct from a null list, which means any application may).\n+\n+Conclusion for acceptance criterion 1. The empty change_acl\n+trusted-application list is not a hardening decision made by LLxprt,\n+@napi-rs/keyring, keyring-core, apple-native-keyring-store, or\n+security-framework. It is the macOS default SecAccess for every item created\n+through SecKeychainAddGenericPassword, and every LLxprt credential item is\n+created through exactly that call. The load-bearing, fully-proven finding is\n+that no layer of the dependency chain exposes any way to supply a different\n+SecAccess, so LLxprt cannot construct or repair the ACL of these items from\n+TypeScript (see 1.3).\n+\n+### 1.3 Why we cannot fix it at the ACL layer\n+\n+The issue's investigation item 2 asked whether items should be created with an\n+explicit SecAccess that keeps change_acl amendable. The answer, from the\n+same source reading, is that there is no API path from TypeScript to do so:\n+\n+- security-framework's macOS module hardcodes SecKeychainAddGenericPassword\n+ in add_generic_password. It exposes no variant taking a SecAccess, and no\n+ kSecAttrAccess pass-through.\n+- apple-native-keyring-store calls set_generic_password with no access\n+ argument and offers no configuration key for one; its only configuration key\n+ is keychain (which of the four keychain domains to use).\n+- @napi-rs/keyring's AsyncEntry surface is getPassword / setPassword /\n+ deleteCredential. It has no access-control surface at all.\n+\n+Constructing a custom SecAccess would require a native change in\n+security-framework (or replacing the binding outright). That is a dependency\n+decision of the same class already deferred in #3011, and it is out of scope\n+here. Investigation item 3 (identity requirement versus cdhash pinning) is\n+likewise unreachable: the trusted-application entries are appended by\n+securityd, not by us, and we cannot choose the requirement form it stores.\n+\n+### 1.4 What is established and what is not\n+\n+The source chain establishes the structural fact above (1.1–1.3): every item is\n+created with the macOS-default ACL, and that ACL cannot be repaired from\n+TypeScript. It does not establish the exact securityd mechanism by which\n+an observed "Always Allow" grant fails to persist. Apple's SecAccessCreate\n+documentation says the owner ACL's empty application list means the user is\n+prompted for permission when the access instance is changed — not that the\n+change is impossible — and Apple's Access Control Lists documentation says\n+"Always Allow" adds the app to the restricted entry's trusted list. Asserting\n+that the empty list is the proven cause of the discarded grant would\n+over-read those documents. Confirming the mechanism would require a native ACL\n+inspection of the item immediately before and after a grant; this work does not\n+perform that inspection and does not assert the mechanism.\n+\n+### 1.5 What is therefore left, and it is the real defect\n+\n+The issue's own failure sequence names step 5 as the defect: "The grant is\n+silently discarded. Nothing is written, and no error surfaces to the user or to\n+SecureStore." This plan does not claim to stop the discard. It can stop the\n+silence, and it can give the user a way out. That is what this plan delivers.\n+\n+## 2. Accepted behavior\n+\n+AB1 — The source-confirmed root cause is documented.\n+Section 1 of this plan is the authoritative record. docs/troubleshooting.md\n+carries the user-facing summary.\n+\n+AB2 — Repeated interactive Keychain authorization is no longer silent.\n+A new dependency-leaf module observes every OS-keyring credential read that the\n+default adapter performs. A read that succeeds but takes longer than the\n+interactive-authorization threshold is recorded as an authorization event for\n+that credential. A second such event for the same credential that\n+began after the first completed is a symptom consistent with a grant that\n+did not persist. This is a heuristic with a known false-positive envelope (a\n+pathologically slow but non-interactive keychain), not proof of the discard\n+mechanism, which this work does not establish (see 1.4).\n+\n+Rationale for this signal, and why there is no better one: the binding erases\n+OSStatus (#3011), securityd handles the ACL append internally and returns\n+the secret regardless, and the ACL is not readable from the binding. The\n+monotonic-clock duration of a successful read is the only in-process\n+observable that distinguishes "authorised without interaction" from "a human was\n+made to authorise this". What narrows the envelope: darwin-only, strictly\n+greater than the threshold, correlation by the same credential,\n+non-overlapping reads only (the second must begin at or after the first\n+completed), and two events rather than one. The consequence is bounded — one\n+stderr notice and a predicate; credential access is never blocked and no data is\n+changed.\n+\n+AB3 — Exactly one actionable diagnostic is emitted, and it never breaks\n+credential access.\n+On the transition to the broken state, one warning block is written to stderr\n+and never repeated for the lifetime of the process. It describes the\n+observation and its consequence (the same credential is being re-authorized\n+after it was already authorized this session, so the grant is not persisting),\n+names the remedies, and references issue 3020. It does not assert a proven\n+cause. Nothing throws; get() still returns the credential it just read.\n+\n+AB4 — A supported recovery path that does not require deleting keychain\n+items.\n+Setting LLXPRT_DISABLE_OS_KEYRING=1 makes createDefaultKeyringAdapter()\n+return null in production. Every credential consumer — SecureStore,\n+machine-secret, and MCP KeychainTokenStorage — obtains its adapter from that\n+one factory, so the single check covers all of them, and all credential traffic\n+routes to the existing encrypted-file fallback. Existing Keychain items are left\n+untouched: nothing is deleted and nothing is migrated.\n+\n+AB5 — The recovery procedure is documented.\n+docs/troubleshooting.md gains the procedure in the existing macOS Keychain\n+section, adjacent to the #3021 ad-hoc-Bun guidance, and states plainly that this\n+is the interim escape hatch pending the full keyring opt-out tracked in #2928.\n+\n+AB6 — Behavioral test evidence exists for every accepted behavior above.\n+\n+### Explicitly out of scope\n+\n+- Constructing a custom SecAccess, or vendoring/patching/replacing\n+ @napi-rs/keyring, apple-native-keyring-store, or security-framework.\n+- The full #2928 work: native OSStatus fidelity, the setter-fallthrough fix,\n+ the session-level "keyring is unusable this session" state transition, and a\n+ settings-file (non-environment) opt-out. LLXPRT_DISABLE_OS_KEYRING here is\n+ the narrow recovery lever #3020 requires, not #2928's design.\n+- Migrating existing Keychain credentials into the fallback store.\n+- Any change to the #3021 launcher warning.\n+- Any change to deletePassword / verifyKeyringDelete (#3011) or to\n+ verifyKeyringWrite (#2927).\n+\n+## 3. Inputs and boundary cases\n+\n+| Input | Accepted result |\n+| --- | --- |\n+| Platform is darwin; one successful keyring read exceeds the threshold | No warning. A single authorization is normal. |\n+| Platform is darwin; a second slow successful read of the same credential that began after the first completed | Broken state becomes true; exactly one warning block on stderr. |\n+| Platform is darwin; two slow successful reads of different credentials | No warning. Different credentials never correlate. |\n+| Platform is darwin; two slow successful reads of the same credential that overlap (the second began before the first completed) | No warning. Concurrent first reads prove nothing. |\n+| Platform is darwin; a third and further slow successful reads | State stays true; no further warning. |\n+| Read duration exactly equals the threshold | Not an authorization event (strictly greater than). |\n+| Slow read that returns null | Not an authorization event. Absence is not a granted authorization. |\n+| Slow read that throws | Not an authorization event, and the rejection propagates unchanged. |\n+| Only fast reads, any number | Never warns. |\n+| Platform is not darwin | Never observes and never warns, whatever the durations. |\n+| LLXPRT_DISABLE_OS_KEYRING=1 | createDefaultKeyringAdapter() resolves null; SecureStore round-trips through the encrypted file; no keychain item is deleted. |\n+| LLXPRT_DISABLE_OS_KEYRING unset, empty, 0, or true | Adapter is created normally. Only the exact string 1 opts out, matching the existing LLXPRT_TEST_DISABLE_OS_KEYRING convention. |\n+| LLXPRT_DISABLE_OS_KEYRING=1 with fallbackPolicy: 'deny' | Existing deny semantics are unchanged: set() raises UNAVAILABLE. The opt-out does not silently defeat a deny policy. |\n+| Runtime already replaced (#2926) | Unchanged. RUNTIME_REPLACED still fires first, before any observation. |\n+\n+## 4. Design\n+\n+### 4.1 New leaf module: packages/storage/src/secure-store/keychain-grant-persistence.ts\n+\n+A dependency leaf, mirroring the established runtime-replaced-errors.ts and\n+runtime-identity.ts conventions (process-wide state, one-time stderr warning,\n+injectable seam so the behavior is testable on every CI platform).\n+\n+ export const INTERACTIVE_AUTH_THRESHOLD_MS = 1500;\n+ export const GRANT_NOT_PERSISTING_MESSAGE: string;\n+ export const GRANT_NOT_PERSISTING_REMEDIATION: string;\n+\n+ export interface KeyringReadObservation {\n+ /* Opaque correlation key for the credential. Map key only; never logged. /\n+ readonly credentialKey: string;\n+ /* Monotonic ms (performance.now) when the native read started. /\n+ readonly startedAt: number;\n+ /* Monotonic ms (performance.now) when the native read completed. /\n+ readonly endedAt: number;\n+ }\n+\n+ /* Records a successful keyring read, correlated by credential. */\n+ export function recordAuthorizedKeyringRead(observation: KeyringReadObservation): void;\n+\n+ export function isKeychainGrantPersistenceBroken(): boolean;\n+\n+ // Test seams\n+ export function resetKeychainGrantPersistenceForTesting(): void;\n+ export function setKeychainGrantPersistencePlatformForTesting(\n+ platform: NodeJS.Platform | null,\n+ ): void;\n+\n+Behavior:\n+\n+- Observations are ignored entirely unless the effective platform is darwin.\n+- Once broken, the state is terminal and no further work is done.\n+- An observation counts only when endedAt - startedAt > INTERACTIVE_AUTH_THRESHOLD_MS.\n+- Observations are correlated by credentialKey in a module-private\n+ Map<string, number> holding the endedAt of each credential's last\n+ interactive read. A credential's first interactive read is normal and is\n+ merely recorded. A second interactive read of the same credential counts\n+ as the discarded-grant event only if it began at or after the first\n+ completed (startedAt >= previousEndedAt); overlapping/concurrent reads prove\n+ nothing and leave the stored value unchanged.\n+- On the counted event the state flips to broken once, the map is cleared,\n+ and the warning is emitted once, to process.stderr.write, wrapped in the\n+ same defensive try/catch runtime-replaced-errors.ts uses for EPIPE.\n+ Losing the notice must never break the credential read.\n+- The map is bounded by MAX_TRACKED_CREDENTIALS = 256. Before inserting a\n+ brand-new key, if the map is full it is cleared first: the tracker only holds\n+ credentials that had exactly one interactive read, entries are only useful for\n+ short-range correlation, and clearing at worst loses a first observation\n+ (biasing toward NOT warning — the safe direction).\n+\n+Threshold and the cap are module constants, not configuration. No new setting.\n+\n+### 4.2 default-keyring-adapter.ts\n+\n+getPassword times the native call with a monotonic clock and reports it:\n+\n+ getPassword: async (service, account) => {\n+ const entry = new kr.AsyncEntry(service, account);\n+ const startedAt = performance.now();\n+ const value = await entry.getPassword();\n+ if (value !== null) {\n+ recordAuthorizedKeyringRead({\n+ credentialKey: ${service}\\u0000${account},\n+ startedAt,\n+ endedAt: performance.now(),\n+ });\n+ }\n+ return value;\n+ },\n+\n+performance.now() is monotonic (unlike Date.now(), which NTP steps and\n+sleep/wake can move). A rejection propagates without being recorded, because\n+the await throws before the record call is reached. This is the only\n+production timing site, so the observation covers SecureStore,\n+machine-secret, and MCP alike. The correlation key is an opaque Map key\n+only — never logged or interpolated into any message.\n+\n+The production opt-out sits beside the existing test marker:\n+\n+ const DISABLE_OS_KEYRING_ENV = 'LLXPRT_DISABLE_OS_KEYRING';\n+ // returns null before the dynamic import, exactly like the test marker\n+\n+### 4.3 secure-store.ts\n+\n+Minimal: one public accessor so the condition genuinely surfaces at the\n+SecureStore boundary named in the acceptance criteria.\n+\n+ isKeychainGrantPersistenceBroken(): boolean {\n+ return isKeychainGrantPersistenceBroken();\n+ }\n+\n+No control-flow change. No new error code. No throw. secure-store.ts is close\n+to the 800-line max-lines ceiling, so nothing else is added there and the\n+threshold is not to be raised.\n+\n+### 4.4 Package exports\n+\n+packages/storage/src/index.ts re-exports\n+isKeychainGrantPersistenceBroken and the two message constants. Nothing else\n+new becomes public.\n+\n+## 5. Test-first evidence\n+\n+All new and changed tests use Bun and bun:test only. No Vitest, no new .js\n+files. New Bun test files must be registered in\n+scripts/bun-test-manifest-data-storage.ts or CI will not run them.\n+\n+New file: packages/storage/test-bun/keychain-grant-persistence.bun.ts\n+\n+RED-first, behavioral, no mock-interaction assertions (no call counters, no spy\n+argument inspection). Assert observable outcomes: the predicate's value and the\n+stderr text. The deterministic clock uses performance.now to match production.\n+\n+1. One slow successful read → predicate false, stderr silent.\n+2. Two slow successful reads of the same credential that are sequential\n+ → predicate true; stderr carries exactly one warning block describing the\n+ observation, naming both remedies, and referencing #3020.\n+3. A third and fourth slow read → predicate still true, stderr unchanged from\n+ case 2 (once per process).\n+4. Duration exactly at the threshold, twice → predicate false.\n+5. Fast reads only, many → predicate false.\n+6. Non-darwin effective platform, many slow reads → predicate false, stderr\n+ silent.\n+7. Two slow successful reads of different credential keys → predicate false\n+ (different credentials never correlate).\n+8. Two slow successful reads of the same credential key that overlap (the\n+ second's startedAt is before the first's endedAt) → predicate false.\n+9. A third credential reaching its first interactive read after the state is\n+ already broken → predicate stays true, stderr unchanged.\n+10. Adapter-level, against the fake @napi-rs/keyring module: two slow\n+ sequential successful reads of the SAME service+account through\n+ createDefaultKeyringAdapter() → predicate true and the value is still\n+ returned to the caller on both reads.\n+11. Adapter-level: two slow reads of DIFFERENT accounts on the same service →\n+ predicate false.\n+12. Adapter-level: a slow getPassword resolving null, twice → predicate false.\n+13. Adapter-level: a slow getPassword that rejects, twice → the rejection\n+ propagates unchanged and the predicate stays false.\n+14. SecureStore surface: with the same fake adapter, after the second slow\n+ get() the store's accessor reports broken and get() still returned the\n+ stored value both times.\n+\n+New file: packages/storage/test-bun/keyring-opt-out.bun.ts (the\n+LLXPRT_DISABLE_OS_KEYRING opt-out cases — see FIX 4; moved out of the Vitest\n+suite):\n+\n+15. LLXPRT_DISABLE_OS_KEYRING=1 → createDefaultKeyringAdapter() resolves\n+ null.\n+16. LLXPRT_DISABLE_OS_KEYRING=1 → SecureStore set/get round-trips through\n+ the encrypted fallback file, and the ciphertext on disk does not contain the\n+ plaintext.\n+17. LLXPRT_DISABLE_OS_KEYRING set to 0, empty, and true → an adapter is\n+ still produced (only exactly 1 opts out).\n+18. LLXPRT_DISABLE_OS_KEYRING=1 with fallbackPolicy: 'deny' → set()\n+ rejects with a SecureStoreError whose code is UNAVAILABLE.\n+\n+Regression guard: the existing LLXPRT_TEST_DISABLE_OS_KEYRING,\n+runtime-replaced, write-verification, and delete-verification suites must stay\n+green and unmodified.\n+\n+Every new test must be run and observed to FAIL before the implementation lands,\n+and the RED observation recorded.\n+\n+## 6. Documentation\n+\n+docs/troubleshooting.md, inside the existing\n+"macOS: Repeated Keychain Password Prompts" section:\n+\n+- The source-confirmed root cause from section 1, condensed: the item's ACL is\n+ the macOS default from SecKeychainAddGenericPassword, its change_acl entry\n+ trusts no application, and no layer of the binding chain can supply a\n+ different one.\n+- The new runtime diagnostic: what the warning means when it appears.\n+- The recovery procedure: export LLXPRT_DISABLE_OS_KEYRING=1, what it does\n+ (encrypted-file fallback in the OS data directory), what it costs\n+ (re-authenticate once; keys already in the Keychain are not migrated), and\n+ that existing Keychain items are left in place rather than deleted.\n+- A note that this is the interim escape hatch and that #2928 tracks the full\n+ opt-out.\n+\n+## 7.

A binary that is ad-hoc signed or has no team ID can never satisfy that requirement. Per [#3020](https://github.com/vybestack/llxprt-code/issues/3020), `change_acl` on these items has an empty application list, so clicking **Always Allow** is silently discarded — the prompt recurs on every credential read. Replacing the binary with Oven's signed build is the only durable fix.\n+**Why \"Always Allow\" does not work:** the Keychain ACL stored on each item is identity-based, so it matches any Oven-signed Bun anywhere on disk. A binary that is ad-hoc signed or has no team ID can never satisfy that requirement. The structural fact, confirmed in source: every LLxprt credential item is created through macOS `SecKeychainAddGenericPassword`, which takes no access-control parameter, so the item's ACL is the macOS default `SecAccess`. That default carries the required **owner** entry authorizing `change_acl` with an **empty** trusted-application list. Per Apple's documentation an empty list means no application is trusted to amend the ACL **without user confirmation** (unlike a null list, which means any application may). No layer of the dependency chain (`@napi-rs/keyring` 1.3.0 → `keyring-core` → `apple-native-keyring-store` 1.0.1 → `security-framework` 3.7.0) exposes any way to supply a different `SecAccess`, so LLxprt cannot construct or repair the ACL of these items from TypeScript. The exact `securityd` mechanism by which the observed \"Always Allow\" grant fails to persist is not established by this work — confirming it would require a native ACL inspection of the item immediately before and after a grant — but the symptom (the prompt recurs on every credential read) is consistent with it. Installing an Oven-signed Bun with a stable team identity clears the symptom in practice.\n \n **Why it is a warning, not a hard failure:** a Bun that is ad-hoc signed or has no team identity runs LLxprt Code correctly in every respect except Keychain access, and some users keep no credentials in the Keychain at all. Failing closed would break those working setups. Skipping it and falling through to the bundled Bun would silently re-enable the npm-unlink failure mode that #2962 exists to prevent, so the launcher warns and continues to use the selected Bun.\n \n@@ -167,6 +167,32 @@ codesign -dv --requirements - \"$(command -v bun)\" 2>&1\n \n This check is macOS-only; Linux and Windows never key credential access on code identity.\n \n+##### Runtime diagnostic: \"the grant is not being persisted\"\n+\n+If the launcher warning was not present at startup (for example, you started LLxprt Code from an Oven-signed Bun but the grant is still not sticking), LLxprt Code watches for the symptom itself: when the **same** credential has to be authorized interactively a second time in a session — after an earlier authorization for it had already completed — it prints a one-time notice to stderr explaining that the grant is not being persisted and that the prompt will keep recurring. This is a heuristic based on how long a successful credential read blocked, so a pathologically slow keychain can also trigger it. Credential access is **not** interrupted by this notice — the value is still read and returned, so your session keeps working. The notice fires at most once per process.\n+\n+##### Recovery: disable the OS keyring\n+\n+If you cannot install an Oven-signed Bun right now, you can route LLxprt's own SecureStore credentials through the encrypted file fallback and leave the Keychain alone:\n+\n+bash\n+export LLXPRT_DISABLE_OS_KEYRING=1\n+```\n+\n+Add this to your shell profile so it persists; do not toggle it per-invocation (see the caveats below). Only the exact value 1 opts out. With it set:\n+\n+- SecureStore credentials (named API keys and similar) are stored in the encrypted file store under your OS data directory (`~/Library/Application Support/llxprt-code/secure-store/` on macOS), using the same AES-256-GCM envelope as the automatic fallback.\n+- Existing Keychain items are left in place — nothing is deleted and nothing is migrated. You will re-authenticate once so the credential is written to the file store.\n+\n+Limitations of this escape hatch (read before relying on it):\n+\n+- MCP server OAuth tokens are not covered. MCP server OAuth uses `KeychainTokenStorage`, which requires the OS keyring and throws when it is unavailable. While this variable is set, MCP server OAuth is unavailable. This is the same pre-existing limitation that already applies on hosts with no keyring at all (headless Linux, containers); it is not specific to this variable.\n+- Stores with `fallbackPolicy: 'deny'` still fail. A store constructed with a deny policy raises `UNAVAILABLE` rather than writing a file. The opt-out deliberately does not defeat a deny policy.\n+- The machine secret can change, and v:2 fallback files are tied to it. When the machine secret lives only in the OS keyring, disabling the keyring makes machine-secret resolution fall through to the file path and generate a different secret. Existing v:2 fallback files then fail to decrypt with a `CORRUPT` error, and files written while opted out likewise fail to decrypt after the variable is removed. This is a loud, visible failure (not silent), which is why the variable should be set persistently rather than toggled per-invocation.\n+- Re-enabling reads the Keychain first. After the variable is removed, `SecureStore.get()` consults the keyring before the fallback file, so a credential you re-authenticated while opted out is silently shadowed by the older Keychain value, and a delete performed while opted out leaves the Keychain item in place. This silent behavior is the other reason to treat the variable as persistent.\n+\n+This is the interim escape hatch for #3020. The full, settings-driven keyring opt-out is tracked in #2928.\n+\n ### Common Authentication Errors\n \n `Failed to login. Message: Request contains an invalid argument`\n"}}
