- operations.md describes two incompatible event-stream designs
`docs/operations.md:320–324` says selecting tasks opens dedicated SSE streams, which is stale against `web/src/state.ts:309–340`, `:401–414`, and says only `agent.delta` is transient though `admin.health` is too. Rewrite the Events section to match the current two-stream feed design, and qualify the transaction/event guarantee at `docs/operations.md:7` for internal bookkeeping writes.
