- A malformed file image URL breaks transcript rendering
`decodeURI` throws on e.g. `file:///tmp/100%.png` (`web/src/markdown.ts:347`), and `renderAll` appends events before mounting the composer (`web/src/task.ts:608–609`), so the rest of the transcript and the composer don't render. Catch the decode error and render the plain fallback link.
- 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.
