+50ms drain interval + monitor return after 8 consecutive empty post-EOF drains (~400ms grace); post-EOF registrations fail fast with retryable CONNECTION_CLOSED; fixed a busy-spin in the old select's eof branch. ADR-070 updated. No public API change.

+FWD-17: non-JSON SSE payloads surface as {data, event} wrapper (event: captured, WHATWG last-wins, leak fixed). FWD-18: structural placeholder values are INVALID_INPUT (no JSON splicing into paths). FWD-19: % in values always encoded, template text preserves pre-encoded % (ADR-066 trust boundary). ADR-066 records all three; SseEvent gained an event field (crate-internal).
