Module watch 

Filesystem-watcher subsystem for --watch DIR mode.

Boots a debounced recursive watcher on the configured directory and invokes a caller-supplied callback when files change. Downstream binaries register callbacks to drive whatever rebuild they need — kglite-mcp-server, for example, wires this to code_tree::build() against the watched directory and atomic-swaps the active graph.

mcp-methods’s binary on its own does not own a rebuild target; it logs change events at INFO level and forwards them to any registered callback. When no callback is set the watcher still runs, so the change events show up in stderr.

Structs

Active watcher handle. Drop to stop watching.

Constants

DEFAULT_DEBOUNCE

Default debounce window — short enough to feel responsive, long enough to coalesce noisy editor saves and IDE temp-file dance.

Functions

Spawn a recursive debounced watcher on dir.

Type Aliases

ChangeHandler

Callback invoked on a debounced file-change event.
