cmux Shared Behavior

Use one shared action/model path when behavior is exposed through multiple entrypoints.

Shared entrypoints

When a behavior is exposed through multiple surfaces, implement one shared action/model path and verify every entrypoint that should invoke it.

Common entrypoints include:

keyboard shortcut
command palette
context menu
CLI/socket command
settings UI
debug menu

Do not patch one surface while leaving the others with duplicated logic.

Optimistic updates

For optimistic UI or CLI updates:

keep one mutation path
record pending state with a request id or previous snapshot
reconcile from the authoritative result
handle failure with an explicit rollback or error state

Do not 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.
