User description

Continues the audit-driven governance cleanup that PRs #506, #507, #509, #510, #512, #522, #525 started. This batch addresses the remaining empty catches and weak peer-dependency fallbacks in plugins, embeddings, oauth, monitoring, and combo paths.

Empty catches fixed (6 sites):

  • src/lib/plugins/loader.ts:200, 301 (plugin load/cleanup)
  • src/lib/plugins/manager.ts:151, 270 (plugin staging cleanup)
  • src/lib/embeddings/service.ts:50, 73 (embedding combo lookup)
  • src/lib/credentialHealth/scheduler.ts:122 (credential health sweep)
  • src/lib/usage/usageStats.ts:301 (usage stats)
  • src/lib/oauth/providers/kimi-coding.ts:44 (OAuth provider init)

Weak peer-dep fallbacks fixed (7 files, 10 call points):

  • src/lib/a2a/skills/providerDiscovery.ts:388 (MCP module load)
  • open-sse/rpc/dispatchEdges.ts:189, 199, 209 (FFI/UDS transport - HIGH RISK, used log.error)
  • src/lib/monitoring/providerHealthAutopilot.ts:262 (quota monitor)
  • open-sse/services/combo.ts:2222 (fetchCodexQuota)
  • open-sse/services/combo/quotaStrategies.ts:431 (getRuntimeProviderProfile)
  • open-sse/handlers/chatCore/codexFailover.ts:19 (provider connection)
  • open-sse/handlers/chatCore/comboContextCache.ts:57 (proxy config)

All conversions preserve existing fallback behavior (return null/false/etc.). Only logging is added - no semantic change.

TSC: 1 pre-existing error in src/lib/db/apiKeys.ts:1056 (PR #505 territory, unchanged).
Targeted tests: 74/74 node:test passing + 29/29 vitest passing.

NOTE: base ref changed from agent/migration-version-collision-fix (deleted in origin after merge of PR #513) to refactor/console-pino-migration-src-20260807 (the previous subagent's branch in the same governance stack, branched from the same bc05496 parent).


CodeAnt-AI Description

Add diagnostic logging while preserving fallback behavior across provider, plugin, embedding, OAuth, and RPC operations

What Changed

  • Failures that previously disappeared silently now produce actionable warning, error, or debug logs.
  • Provider, proxy, quota, MCP, and RPC module failures continue using their existing fallbacks, such as native mode, skipped optional sources, empty results, or undefined responses.
  • Plugin cleanup, OAuth device-file permissions, credential health checks, usage statistics, and embedding setup still continue when non-critical operations fail, while recording the reason.
  • Embedding and combo behavior remains unchanged, including dimension validation and fallback decisions.

Impact

✅ Clearer operational failure diagnostics
✅ Preserved provider and plugin fallback behavior
✅ Easier troubleshooting of optional dependency failures

…5 modules (#506)

Builds on PR #505 (quota keystore type-drift fix). The audit of that PR
revealed 5 additional silent fail-open catch patterns across `src/` and
`open-sse/` that hide the same class of bug: a TypeScript compile error
or missing module is silently swallowed at runtime, falling back to a
default with no operator-visible signal.

This commit replaces those silent catches with explicit `log.error` calls
that surface the actual error to monitoring. Fallback behavior is
preserved (each fallback is intentional, but it must be LOUD).

Changes:

1. `src/lib/quota/storeFactory.ts:67-77` — `readDbSettings` now logs the
   actual error when `getSettings()` fails or `@/lib/db/settings` import
   fails. Same root cause as the previously-fixed Keyv/Redis catches.

2. `src/lib/quota/storeFactory.ts:138-147` — Redis driver catch upgraded
   from `log.warn` to `log.error`. Includes the configured Redis URL
   with the password segment redacted (`:***@`).

3. `src/lib/resilience/anomalyHook.ts` — `getProviderManagerRegistry`
   now logs the actual error when `@/engine/providers` fails to load.
   Empty Map fallback retained (resilience must continue running), but
   the failure is now visible in monitoring.

4. `open-sse/services/tierResolver.ts` — `setTierConfig` now logs the
   actual error when `../../src/lib/db/tierConfig` fails to load.
   `DEFAULT_TIER_CONFIG` fallback retained (pricing must continue), but
   the failure is now visible.

5. `open-sse/config/credentialLoader.ts` — `resolveCredentialsPath` now
   uses `log.error` (pino) instead of `console.warn`. Includes both the
   original error and the fallback path. Security-sensitive path; must
   keep working, but the failure must be loud.

6. `.gitignore` — exclude `.agileplus/` and `agileplus-*.db*` (local
   AgilePlus DB state, regenerated from `.md` specs via `agileplus
   specify`). The DB contains transient per-machine state and shouldn't
   be in version control.

Verification:
- TSC: 0 NEW errors (8 pre-existing quota keystore errors remain, those
  are what PR #505 fixes; this PR is independent of PR #505)
- Vitest quota suite: 18/18 pass (6 keyv + 4 contract + 8 e2e)
- Node:test factory: 6/6 pass
- Resilience tests: 61 pass / 1 pre-existing flake
  (resilience-provider-cooldown-api-3556.test.ts: "rejects providerCooldown
  max below min" — verified pre-existing by reverting only anomalyHook.ts
  and reproducing the same failure)

Out of scope (filed as separate bugs):
- `src/lib/resilience/anomalyHook.ts:13` imports `isFeatureFlagEnabled`
  from `@/lib/featureFlags`, but the module lives at
  `src/lib/db/featureFlags.ts`. The file is currently unloadable from
  tests; this PR doesn't touch the import because that's a separate bug.
- The Resilience subagent identified but did not fix the
  `tsconfig.typecheck-core.json` doesn't include `src/lib/resilience/`
  files — separate follow-up.

…extras test (#507)

Continuation of the governance-debt cleanup started in PRs #505 and #506.
Six independent fixes, each addressing a class of silent-failure pattern
that the audits surfaced.

Changes:

1. **`src/lib/resilience/anomalyHook.ts:12`** — Broken import path.
   `isFeatureFlagEnabled` was imported from `@/lib/featureFlags`, but
   the module lives at `@/shared/utils/featureFlags`. This bug was
   masked because `tsconfig.typecheck-core.json` does not include
   `src/lib/resilience/` and no test loads the module successfully.
   After the fix, the module loads and exports the expected surface.

2. **`src/server-init.ts:128`** — Same broken import path. The
   surrounding try/catch at lines 130-139 silently swallowed the
   import failure. Fix: correct the path AND upgrade the catch log
   from `warn` to `error` (matches PR #506 pattern).

3. **`src/lib/versionManager/processManager.ts:155`** — `getProcessInfo`
   catch returned `{pid, alive: true}` after `ps`/readFile failures,
   which lies when the process is actually gone. Fix: catch now
   logs the error and returns `{pid, alive: false}` (honest about
   not being able to read process state).

4. **`src/server/ws/liveServer.ts:479`** — `loadAuthModule().catch(() => {})`
   silently swallowed initial auth module load failures, allowing the
   WS server to come up without auth configured. Fix: catch now logs
   `log.error`; fallback behavior preserved per the existing comment
   ("handler retries the import lazily").

5. **`src/lib/machineToken.ts:1-10`** — Crypto-relevant: empty catch
   around `require("node-machine-id")` silently fell back to
   `() => ""`, which collapses HMAC inputs to a constant. Fix: catch
   now logs `log.error` with security-context message, gated by a
   `fallbackLogged` flag so the log fires only once per process
   (avoiding log spam from any downstream reload).

6. **`tests/unit/quota/keyvQuotaStoreExtras.test.ts`** (new) — Closes
   spec §8.2 reachability test gap. 5 sanity tests for the
   `recordPlanUsage` / `upsertProviderPlan` / `listProviderPlans` /
   `setPools` / `getPool` surface on KeyvQuotaStore. Note: this
   branch is based on `origin/agent/migration-version-collision-fix`
   (pre-PR-#505), so the methods live directly on KeyvQuotaStore.
   When PR #505 lands, update the test to import from
   `keyvQuotaStoreExtras.ts` instead.

Verification:
- TSC error count: 8 unchanged (all pre-existing quota keystore
  errors that PR #505 fixes; this PR is independent of #505)
- Vitest extras test: 5/5 pass
- Node:test combined (processManager + machineToken + WS): 47/47 pass
- All success-path behavior preserved; only catch/fallback paths now log

Out of scope (separate PRs):
- Promote Keyv to "embedded default" driver (spec §10)
- Pre-existing e2e failure at `tests/e2e/quota-store.e2e.ts:117`
  (poolUsageWithDimensions shape mismatch — fixed in PR #505)

…onical base) (#509)

This branch has been surgically rebased onto origin/agent/migration-version-collision-fix
to remove accidental contamination from PR #507's branch base.

In all three cases, the empty-string return collapses HMAC/HMAC-SHA256
inputs into a constant-key value, so security-relevant operations on the
fallback path produce identical tokens regardless of input.

Fixes:
1. src/lib/machineToken.ts:44 - getMachineTokenSync catch:
   log.error + return ""
2. src/lib/machineToken.ts:62 - getLegacyCliTokenSync catch:
   log.error + return ""
3. src/lib/db/encryption.ts:87-95 - getLegacyDynamicKey catch:
   added pino logger (createLogger("db:encryption")) + log.error
   instead of returning null silently
4. (incidental) src/lib/machineToken.ts module-load catch: also
   gains log.error so the new runtime catches have a 'log' constant
   to reference. This subsumes PR #507's machineToken.ts hunk.

NOTE: PR #507 will need its machineToken.ts hunk resolved when it merges
(this branch already provides the 'log' logger constant it tries to add).

Verification:
- TSC: 8 unchanged (pre-existing quota keystore errors, PR #505 territory)
- Targeted machineToken + encryption unit tests pass
- All success-path behaviors preserved

Completes the audit-driven governance work that PR #509 started. Eight
independent fixes:

Security fixes (audit findings F5, F6, F9, F10):

1. src/lib/cloudSync.ts:47-56 — HMAC verification fail-open when
   CLOUD_SYNC_SECRET is unset. Now returns false (fail-closed) when a
   sigHeader is present but cannot be verified, instead of accepting
   any response. Legacy unverified mode (no sigHeader) is preserved.

2. src/lib/oauth/providers/antigravity.ts:101 — fetch() of userInfo
   during OAuth was swallowed silently, causing downstream code to use
   default projectId/tierId. Now logs warn with structured context.

3. open-sse/services/autoRefreshDaemon.ts:77,80 — periodic credential
   refresh errors were silently swallowed, allowing expired tokens to
   persist undetected. Now logs error per cycle.

4. src/lib/vscode/serviceTierVariants.ts:184 — request body parse
   failures during tier-rewrite were silently no-op'd. Now logs warn.

Refactor:

5. src/lib/db/encryption.ts — migrated ~7 console.* calls to pino
   logger (encryptionLog). Following the PR #509 pattern of
   createLogger("db:encryption"). The catch fallback behavior is
   preserved exactly; only logging changes.

Out of scope:
- encryption.ts:144-148 plaintext fallback (separate spec at
  plans/encryption-failclosed-spec.md, deferred for design discussion)
- src/lib/db/*.ts console.* migration for other files (separate PR)

Co-authored-by: KooshaPari <koosha@example.com>
22 silent fail-open sites in the version manager + SQLite adapter layer
were just swallows. Per the audit:

- src/lib/versionManager/binaryManager.ts (6 catches): symlink/rollback/
  remove errors were silent; filesystem permission bugs were invisible
- src/lib/db/adapters/sqljsAdapter.ts (6 catches): save/close errors
  were silent; DB corruption during shutdown was undetectable
- src/lib/db/adapters/betterSqliteAdapter.ts (1 catch): same pattern
- src/lib/db/adapters/nodeSqliteAdapter.ts (2 catches): same pattern
- src/lib/db/adapters/nodeSqliteShared.ts (7 catches): same pattern

All 22 catches now log structured error context. Behavior unchanged -
only logging added. Per AGENTS.md, no encryption keys or raw secrets
are logged.

TSC: 8 unchanged
Tests: existing pass (any new behavior is logging-only)

Two deferred-implementation specs are now tracked in version control so
the work product is preserved and discoverable.

1. plans/encryption-failclosed-spec.md (883 lines) — Hardening
   encryption.ts:144-148 (the silent plaintext fallback). Compares 3
   design options with detailed tradeoffs. Recommended: C+A
   (startup canary + runtime throw). Registered as AgilePlus
   feature 'encryption-failclosed'.

2. plans/keyv-as-embedded-default-spec.md (698 lines) — Promote Keyv
   from optional driver to embedded default for fresh installs.
   Includes backwards-compat plan, config migration, and rollout
   sequence. Registered as AgilePlus feature 'keyv-as-embedded-default'.

These specs intentionally do NOT include code changes — they are
design-only and gate on answering the open questions before
implementation. See spec section 9 for each spec's open questions.

Follows the PR #506/#507/#509/#510 pattern of replacing console.*
with createLogger("db:<subsystem>") to provide structured logging
across the SQLite persistence layer.

Files modified (~155 callsites across 17 files):
- src/lib/db/adapters/driverFactory.ts
- src/lib/db/adapters/sqljsAdapter.ts
- src/lib/db/apiKeys.ts
- src/lib/db/backup.ts
- src/lib/db/cleanup.ts (~30 sites)
- src/lib/db/core.ts (~30 sites)
- src/lib/db/migrationRunner.ts (~22 sites, removed test-suppressing local console wrapper)
- src/lib/db/models.ts
- src/lib/db/optimizationSettings.ts
- src/lib/db/providers.ts
- src/lib/db/quotaPools.ts
- src/lib/db/quotaSnapshots.ts
- src/lib/db/schemaColumns.ts (~35 sites)
- src/lib/db/sessionAccountAffinity.ts
- src/lib/db/settings.ts
- src/lib/db/settings/cacheMetrics.ts
- src/lib/db/stateReset.ts

Per AGENTS.md guidance, never log SQLite encryption keys or raw secrets;
all logger calls redact sensitive material.

Behavior preservation:
- All success-path behavior unchanged
- Only the logging mechanism changes
- Targeted tests pass

One console.error preserved in core.ts:migrateFromJson because
tests/unit/db-core-migration.test.ts overrides console.error to detect
the failure; both console.error and log.error are emitted so the test
passes and pino is the canonical sink.

…ollowup)

Continues the audit-driven governance cleanup that PRs #506, #507, #509,
#510, #512, #522, #525 started. This batch addresses the remaining empty
catches and weak peer-dependency fallbacks in plugins, embeddings,
oauth, monitoring, and combo paths.

Empty catches fixed (~6 sites):
- src/lib/plugins/loader.ts:200, 301 (plugin load/cleanup)
- src/lib/plugins/manager.ts:151, 270 (plugin staging cleanup)
- src/lib/embeddings/service.ts:50, 73 (embedding combo lookup)
- src/lib/credentialHealth/scheduler.ts:122 (credential health sweep)
- src/lib/usage/usageStats.ts:301 (usage stats)
- src/lib/oauth/providers/kimi-coding.ts:44 (OAuth provider init)

Weak peer-dep fallbacks fixed (~10 sites):
- src/lib/a2a/skills/providerDiscovery.ts:388 (MCP module load)
- open-sse/rpc/dispatchEdges.ts:189, 199, 209 (FFI/UDS transport —
  HIGH RISK, used log.error not warn)
- src/lib/monitoring/providerHealthAutopilot.ts:262 (quota monitor)
- open-sse/services/combo.ts:2222 (fetchCodexQuota)
- open-sse/services/combo/quotaStrategies.ts:431 (getRuntimeProviderProfile)
- open-sse/handlers/chatCore/codexFailover.ts:19 (provider connection)
- open-sse/handlers/chatCore/comboContextCache.ts:57 (proxy config)

All conversions preserve existing behavior (return null/false/etc.).
Only logging is added — no semantic change. Test results unchanged
from baseline.

TSC: 8 unchanged (pre-existing quota keystore errors, PR #505 territory).

Suggestion: A transient database failure is converted into the native/disabled configuration and cached for the full 10-second TTL. resolveExecutorWithProxy uses this cached value to bypass the configured proxy or fallback executor, so subsequent requests remain incorrectly routed even after the database becomes available. Do not cache an error fallback, or use a separate short-lived failure cache with retry behavior. [cache]

Severity Level: Major ⚠️
- ⚠️ Chat requests bypass configured upstream proxy routing.
- ⚠️ CLIProxyAPI fallback is unavailable during the cache window.
- ⚠️ Proxy configuration recovers only after TTL expiration.
