Module watch 

The tear-sanctioned watcher backend, with the polling-backend exclusion asserted at startup (F-7b constraint 4, condition 3).

notify ships a PollWatcher fallback, and silently resolving to it on any platform would smuggle the banned shape through a sanctioned door. RecommendedWatcher resolves at compile time; this module asserts the resolved backend is a NATIVE event one (FSEvents on macOS, inotify on Linux) and refuses typed before any watch is established otherwise. Kqueue is refused too: the ruling names FSEvents/inotify, and widening it is a tear question, not a worker choice.

Structs

NonNativeBackend

Typed startup refusal for a non-native watch backend.

WatchedSet

The watched set of one generated project (F-7b R2): the component manifest and the component sources, nothing else.

Enums

Classification

What one watcher event means to the dev loop.

Functions

assert_native_backend

Asserts the compile-time-resolved watcher backend is a native event backend, returning it for the startup report. Called before any watch is established; the typed refusal aborts frame dev loudly.
