🟠 High usage/UsageService.ts:252
A malformed Codex entry causes readSummary to throw and return no usage from any configured directory. Schema.decodeSync(CodexSettings) at this point is not caught, so invalid or legacy providerInstances entries escape the Effect error boundary; decode with an Effect/catch and skip or report the invalid instance instead.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — The production change broadens usage scanning and metering to all configured Codex homes, changing runtime processing and reported limits for multi-account setups. An unresolved high-severity case also indicates malformed instance configuration can abort the overall usage read. Not approved because:

When a Codex instance leaves config.homePath empty but supplies CODEX_HOME through its supported environment list, CodexSessionRuntime runs the provider against that environment path, while this call resolves the default ~/.codex path instead. Multiple environment-only accounts consequently collapse to the same default directory and their real transcripts remain excluded, so usage still underreports; resolve the scan path with the same environment precedence used by the Codex driver.

ProviderInstanceConfig.config is deliberately Schema.Unknown, and the provider registry treats a driver-specific decode failure as an unavailable instance rather than invalidating all server settings. Therefore a persisted entry such as { driver: "codex", config: { homePath: 123 } } can reach this branch, where decodeSync throws a defect outside the declared UsageReadError channel and causes the entire usage RPC—including Claude and valid Codex sources—to fail. Decode effectfully and either skip the unavailable instance or map the failure to scanFailed.
Useful? React with 👍 / 👎.

This regression test reconstructs the enumeration and deduplication logic locally instead of invoking UsageService, so it remains green if resolveTranscriptDirs stops iterating providerInstances—the exact regression it claims to prevent—or if the production decoder and settings wiring behave differently. Cover the service through focused layers or extract and directly test the production helper.

Map invalid instance settings to UsageReadError.
If providerInstances can contain an invalid Codex configuration, replace Schema.decodeSync with effectful decoding and map its failure to UsageReadError. Schema.decodeSync throws when parsing fails, and this loop has no local conversion to the scanFailed error path. This can stop the usage scan outside its declared error contract. (effect.website)
Confirm that ServerSettings validates every Codex instance.config as CodexSettings before UsageService reads it. If it does not, preserve the existing settings-failure behavior here.

UsageService.resolveTranscriptDirs only scanned the legacy single-instance Codex config and ignored additional instances configured via providerInstances. Multi-account setups had their session directories excluded from usage scans, causing incorrect limit reporting. Updated to enumerate all Codex instances from both configs, decode each instance settings, resolve home layouts, and collect unique session directories with deduplication.
Fixes #11515
