Grillo — Chat Observer Beat

Part of the G.R.I.L.L.O. background subsystem.

Purpose

Passively watches recent conversations. It samples chat snippets, optionally stores passive memories from them, and — within strict anti-spam guards — can propose proactive outreach so Synth can gently re-engage a quiet conversation instead of only ever replying.

Beat

Trigger: periodic (its own interval, GRILLO_OBSERVER_INTERVAL).
Output: proposed chat snippets for processing and/or passive memories.

How it works

On each run the plugin looks at conversations active within GRILLO_OBSERVER_ACTIVITY_WINDOW_DAYS. Proactive messaging is heavily guarded: if the synth was the last to speak in a conversation, outreach to it is blocked for GRILLO_OBSERVER_SELF_COOLDOWN_DAYS (or, when that is 0, for GRILLO_OBSERVER_SELF_COOLDOWN_MINUTES), and quiet hours are respected via GRILLO_OUTREACH_QUIET_MINUTES. The last run is tracked in GRILLO_OBSERVER_LAST_RUN_TS. Discovery is automatic via the plugin registry.

Configuration

Key	Purpose
`GRILLO_OBSERVER_ENABLED`	Enable/disable the observer.
`GRILLO_OBSERVER_INTERVAL`	Seconds between observer runs.
`GRILLO_OBSERVER_STORE_MEMORIES`	Whether to store passive memories from snippets.
`GRILLO_OBSERVER_ACTIVITY_WINDOW_DAYS`	How recent a conversation must be to consider.
`GRILLO_OBSERVER_SELF_WINDOW`	Window used when evaluating the synth’s own recent messages.
`GRILLO_OBSERVER_SELF_COOLDOWN_DAYS`	Anti-spam: days to forbid outreach after the synth spoke last (0 = use minutes).
`GRILLO_OBSERVER_SELF_COOLDOWN_MINUTES`	Fine-grained anti-spam cooldown when the days cooldown is 0.
`GRILLO_OUTREACH_QUIET_MINUTES`	Quiet period during which proactive outreach is suppressed.
