Package events implements the R2 dashboard's SSE broker (plan task t04-sse-broker): an in-process fan-out from event sources to per-client bounded buffers.

Package handlers implements the R2 observability dashboard's REST API (plan task t03-handlers-rest) per the pinned contract in .agents/workflow/plans/r2-observability-dashboard/design/API.md.

r3mount.go mounts the R2 observability dashboard INSIDE the R3 background-worker service (task t13-r3-mount-integration): it composes the dashboard's store → broker → handlers collaborators, stitches the REST/SSE handler mount onto R3's HTTP/SSE edge via RegisterMount (spec D5 — the browser-facing arm of the r3 §2A surface→transport map, NEVER the UDS control plane), and bridges R3's EventBus into the broker so R3's in-process publish is the dashboard's PRIMARY event source.

Package store is the R2 observability dashboard's read-through data layer.

Package watch is the t06 iter-log filesystem watcher → SSE-broker bridge (plan task t06-recompute-on-miss-and-fswatch): the v1 standalone push path that exists BEFORE R3's publish primitive lands.
