Shared entrypoints

When a behavior is exposed through multiple surfaces (keyboard shortcut, command palette, context menu, CLI/socket command, settings UI, debug menu), implement one shared action/model path and verify every entrypoint that should invoke it. Do not patch one surface and leave the others with duplicated logic.

Optimistic updates

Keep one mutation path. Record pending state with a request id or a previous snapshot, reconcile from the authoritative result, and handle failure with an explicit rollback or error state. Never let each entrypoint maintain its own optimistic copy.

Missed-bug coverage

When a user says tests missed a bug, add or adjust behavior-level coverage around the exact repro path before claiming the fix is complete.
