 - ✅ F-006 addressed: inbound HTTP request bodies now enforce a configurable max-size limit (`server.max_request_body_bytes`) with `413 Payload Too Large` responses.
 - ✅ F-007 addressed: `ToolExecutor` timeout timer handles are now cleared in `finally`, preventing orphan timers on fast/failed tool calls.
 - ✅ F-016 partially addressed: gateway + webhook body readers were consolidated into shared utility `src/utils/httpBody.ts` with size-limit enforcement.
+- ✅ F-005 addressed: ESLint JS globals now include `FileReader`, removing UI false-positive lint failures for attachment handling code.
+- ✅ F-010 addressed: `session.compact` audit events now emit actual message counts for `messages_before/messages_after` (tokens remain in token fields).
+- ✅ F-012 addressed: synthetic repeated-tool nudge no longer emits invalid `tool_result.tool_use_id`; nudge is injected as plain user text guidance.
