Summary

  • A pidless auth-profiles.lock (left by a kill/crash mid-write) was reclaimed only after the full 30s stale-age, so acquire_lock blocked ~30s on reopen.
  • app_state_snapshot — what the FE gates "Initializing OpenHuman" on (PublicRouteisBootstrapping) — ran its two backend enrichments sequentially, adding ~15s when the backend was unreachable.
  • Net: a kill+reopen (esp. on a flaky network) stranded the user on the loading screen for ~30–42s, effectively "stuck."
  • Keychain errors logged only the lossy Display ("No matching entry found in secure storage"), hiding the variant/OSStatus — undiagnosable without Console.app.

Problem

"Initializing OpenHuman" hung after killing and reopening the app (reported on a macOS staging build). From a user log, the first app_state_snapshot took 42,826 ms because three things serialized while degraded: the auth-profile file lock (~30s on a stale pidless lock — [credentials] lock … has no parseable pid line; leaving in place), build_runtime_snapshot (10s timeout), and fetch_current_user (5s timeout), with the backend intermittently unreachable. The FE clears isBootstrapping only when that first snapshot returns, so the loading screen stayed up the whole time.

Solution

  • credentials/profiles.rs — fast pidless-lock reclaim. A lock with no parseable pid= line can only be a crash/kill artifact (a healthy holder writes its pid microseconds after create_new), so reclaim it after a short MALFORMED_LOCK_GRACE_MS (2s) instead of the full STALE_LOCK_AGE_MS (30s). Valid-pid paths unchanged (dead → immediate, live+leaked → 30s). 30s → ~2s.
  • app_state/ops.rs — concurrent enrichments. Run the current-user refresh and runtime snapshot under tokio::join! (both immutable-borrow &config, both already fall back to local data). Unreachable-backend worst case ~15s → ~10s. Net boot worst case ~42s → ~12s; sub-second when reachable.
  • keyring/* + credentials/profiles.rs — diagnostics. New KeyringError::diagnostic() (Debug — variant + boxed source chain, which carries the macOS OSStatus for PlatformFailure; no secret values) appended at every keychain error/swallow site; is_available=false and use_keychain=false now log at warn/info so the silent fallback flip is visible. Logging only.

Submission Checklist

  • Tests added or updated — clear_lock_if_stale_reclaims_pidless_lock_past_short_grace (new) + the existing fresh-lock leave-alone test still holds; app_state snapshot tests cover the concurrent path.
  • Diff coverage ≥ 80% — ran focused cargo test (credentials::profiles 35, app_state 25, keyring 46) + cargo fmt --check locally; full cargo-llvm-cov/diff-cover not run locally — relying on CI to enforce.
  • Coverage matrix updated — N/A: latency/robustness + logging change on an existing path; no feature row added/removed/renamed.
  • Affected feature IDs listed — N/A: no matrix feature touched.
  • No new external network dependencies — none (the two existing backend calls now run concurrently; no new endpoints).
  • Manual smoke checklist — N/A: no new manual step; faster/bounded boot on the existing path.
  • Linked issue closed via Closes #NNNN/A: self-identified from a user-reported staging hang; no tracking issue.

Impact

  • Platform: desktop (all) — lock + snapshot paths are shared core. The keychain-error detail is most useful on macOS (carries OSStatus).
  • Performance: "Initializing OpenHuman" after kill/reopen drops from ~30–42s to ~2s (working network) / ~12s worst case (unreachable backend), then renders degraded — no longer "stuck forever."
  • Security/compat: none. No secret values logged (only the namespaced key, already in Display). No schema/migration change.

Related

  • Closes: N/A (no tracking issue)
  • Follow-up PR(s)/TODOs: separate "random logout" classifier fix (a transient local no backend session token should not clear the session); the staging-api DNS flakiness on the affected machine is environmental.

📝 Walkthrough

Walkthrough

This PR improves error observability and reliability across keyring operations and auth profile persistence, and parallelizes snapshot construction to reduce latency. The changes add a keyring error diagnostic method, enrich error logging with debug details, improve lock stale recovery for incomplete lock files, and enable concurrent auth-user and runtime-snapshot building with independent timeouts.

Changes

Error Diagnostics and Snapshot Concurrency

Layer / File(s) Summary
Keyring error diagnostic method
src/openhuman/keyring/error.rs
Introduces KeyringError::diagnostic(&self) -> String that formats the error as its Debug representation for richer logging.
Keyring operation logging improvements
src/openhuman/keyring/ops.rs, src/openhuman/keyring/encrypted_store.rs
Updates get, set, delete operations and is_available() probe to include e.diagnostic() in warning/error logs. Elevates is_available() failure from debug to warn level. Legacy key migration logging also enriched with diagnostic detail.
Auth profile keychain storage and fallback logging
src/openhuman/credentials/profiles.rs
Improves keychain persistence observability: AuthProfilesStore::new logs when falling back to encrypted JSON, keychain_store_secrets wraps set failures with diagnostic detail, and keychain_load_secrets/keychain_delete_secrets include diagnostic output in error logs.
Lock stale recovery for pidless (malformed) locks
src/openhuman/credentials/profiles.rs, src/openhuman/credentials/profiles_tests.rs
Adds MALFORMED_LOCK_GRACE_MS constant and refactors clear_lock_if_stale() to distinguish malformed pidless locks from normal stale locks, enabling faster recovery (short grace) for incomplete lock files left by mid-write crashes. Includes regression test covering the new grace window.
Concurrent snapshot building
src/openhuman/app_state/ops.rs
Parallelizes snapshot() by running auth current-user refresh and runtime snapshot construction concurrently via tokio::join! with independent timeouts and fallback behaviors. Updates timing diagnostics to report auth_ms, enrich_ms, local_state_ms, and total_ms.

Poem

🐰 A lock once lost in the chaos of time,
Now finds its grace through a clever design,
While snapshots join hands and race side by side,
With logs shining bright as the keyring's good guide!

…g ~30s

A kill/crash between `create_new` and the `pid=` write leaves a malformed
(pidless) `auth-profiles.lock`. The old stale-check only reclaimed such a lock
once it crossed STALE_LOCK_AGE_MS (30s), so on reopen `acquire_lock` — taken by
`app_state_snapshot` via `load_app_session_profile` — blocked ~30–35s. The FE
gates "Initializing OpenHuman" (PublicRoute → isBootstrapping) on that first
snapshot, so the user is stuck on the loading screen for the whole window after
a kill+reopen (observed: app_state_snapshot 42826ms; lock "has no parseable pid
line; leaving in place").

A pidless lock can only be a crash artifact — a healthy holder writes its pid
microseconds after create_new — so reclaim it after a short MALFORMED_LOCK_GRACE_MS
(2s) instead of the full 30s. The grace stays non-zero so we never reclaim a live
writer mid-create_new/pid= window. Valid-pid (dead → immediate; live+leaked → 30s)
paths are unchanged.

Test: clear_lock_if_stale_reclaims_pidless_lock_past_short_grace (pidless lock
aged past the grace but well under STALE_LOCK_AGE_MS is now reclaimed); the
fresh-lock (<grace) leave-alone test still holds.

…esn't stall

`app_state_snapshot` is what the FE blocks on while showing "Initializing
OpenHuman" (PublicRoute → isBootstrapping clears on the first snapshot). It ran
the two backend-touching enrichments — current-user refresh (AUTH_FETCH_TIMEOUT
5s) and the runtime snapshot (RUNTIME_SNAPSHOT_TIMEOUT 10s) — sequentially, so a
machine that can't reach the backend waited ~15s before falling back to the
already-available local data (stored_user / degraded runtime).

Run them concurrently with tokio::join! (both have local fallbacks, both only
touch &config immutably). Worst-case bootstrap latency drops from ~15s to ~10s
on an unreachable backend; with the auth-profile lock reclaim fix it goes from
the observed ~42s to ~12s, and is sub-second when the backend is reachable. The
FE clears isBootstrapping on this first snapshot, so "Initializing" no longer
hangs after a kill+reopen.

We were blind diagnosing the macOS keychain failure: the OS backend wraps
`keyring::Error` and we logged only its Display, which collapses to
"No matching entry found in secure storage" (keyring's `NoEntry`) — hiding the
variant and any `OSStatus`, so a locked keychain, a denied prompt, and a missing
entitlement all look identical without Console.app.

Add `KeyringError::diagnostic()` (Debug of the error — variant + boxed source
chain, which for `PlatformFailure` carries the security-framework OSStatus; safe
to log, no secret values) and append it at the keychain error/swallow sites:
get/set/delete (ops.rs), the `is_available` probe failure (now `warn`, since it
silently flips `use_keychain`), `keychain_{store,load,delete}_secrets`
(profiles.rs), and the master-key migration + load (encrypted_store.rs). Also
log at info when `use_keychain` is false — the state change behind the
"no backend session token" confusion.

No behavior change; logging only.
