Revive heartbeat state and cool empty-room loops

@@ -176,6 +176,7 @@ Within the Postgres path, the implementation is split on purpose now too:
 1. The Windows scheduled task `Void Mood Drift` starts `scripts/run-void-mood-drift.ps1` every 5 minutes.
 2. That wrapper calls `node scripts/simulate-void-mood.mjs`, which reads canonical moderation state from `.voidbot/private/moderation-agent-state.msgpack`, then refreshes the editable JSON working projection after each pass.
 3. The script first runs `scripts/void-memory-organ.mjs` over the shared self-state: episodic/semantic/musing/dream memories plus recent repo/archive/runtime seeds get compact semantic vectors, the strongest cross-memory similarities become `moderation_runtime.memory_resonance`, and the best cluster candidates are promoted into `moderation_runtime.incubation`.
+   The collector now intentionally downweights repetitive empty-room bookkeeping, so strings like `no new messages / no smoke / no post` stop masquerading as the deepest thought in the machine just because the room stayed quiet for a while.
 4. It then nudges each canonical-state `current_activation` toward a Perlin-shaped target centered on the vector mean, with excursion size and drift rate governed by plasticity and category-specific tempo.
 5. The same script also maintains `moderation_runtime.sleep_cycle`: every four hours it opens a one-hour nap window, marks the shared self-state as napping or awake, and adds a small sleep-bias push toward exhaustion, figurative language, self-disclosure, and reduced technical density while the nap is active. During those nap windows it can also create or reinforce distilled dream residue from the strongest incubating thought.
 6. It also reads `.voidbot/status/void-last-speech.json` so recent actual speech damps `needToSpeak` instead of letting the herald impulse climb forever like a busted pressure gauge.
