The system-message developer block was rebuilt every turn with two unstable inputs: minute-precision current_datetime in the middle of the composed prefix, and _pending_nudge entries appended-then-cleared at the bottom. Both invalidated prompt-cache reuse on Anthropic / OpenAI for the entire prefix, every turn. current_datetime now rounds to the top of the hour. Nudges no longer ride on the system message at all — they drain through two channels: - tool_error and repeat ride the existing tool-result <system-reminder> envelope via a new MetacognitiveAdvisory ToolAdvisory subtype, drained in _collect_advisories alongside GuardAdvisory and UserInterjection. - correction, denial, resume, start, completion splice as <system-reminder> blocks at the trailing edge of the next user message via a new _splice_pending_user_advisories helper. User content passes through escape_wrapper_tags before concatenation so a user typing literal <system-reminder> tags cannot fabricate an envelope; the same escape now runs on advisory.render() output inside wrap_tool_result for defense-in-depth across all advisory types. Cancel handlers (GenerationCancelled / KeyboardInterrupt / bare Exception) now clear _pending_tool_advisories alongside the existing _flush_queued_messages so a queued nudge from an aborted batch cannot leak into the next generation. Visibility ping ([metacognition: nudge injected — ...]) preserved at both new attach points via a single _emit_nudge_ping helper. Also adds a "Session kind" line (interactive | coordinator) to the composed Session Context so the model can see which manager hosts its session. Tests: 4847 passing (+7 new in TestMetacognitiveBuffers and test_tool_advisory). ruff + mypy clean.
