Input Method Keeper v0.3 makes pane-local input-source memory quieter, faster, and self-maintaining without adding a daemon or rule engine.
Highlights:
- Guarded current-session pane reconciliation with read-only health reporting and explicit doctor cleanup.
- Lower focus-path overhead through socket-first Herdr calls, input-source query reuse, and unchanged metadata suppression.
- Bounded, concurrency-safe focus and debug logs with dashboard health summaries.
- Quiet defaults for new installs: focus notifications now default off, while existing configs remain unchanged.
- Fail-open handling for malformed pane snapshots, corrupt state, backend failures, and maintenance contention.
Validation:
- 94 unit and smoke-contract tests passed.
- Isolated Herdr 0.7.4 smoke passed for complex fake, fake backend, and real ABC/WeType input-source actions.
- Reference sample: already-current p95 254 ms; selected p95 283 ms.
