feat(runtime/coach,persona): death post-mortem coach + Russian chat narration
Coach (runtime/coach/postmortem.js):
- bot.on('death') → captures context (last skill, hostile, recent
scenarios, journal nearby, snapshot) → inserts row into knowledge.deaths
- Periodic drain (every 5min, ≤3 Pi calls/hour, 12min cooldown):
batches up to 8 unanalysed deaths, asks Pi to extract 1-3 generalised
lessons in JSON, persists to knowledge.lessons + knowledge.postmortems
- Pi prompt asks for structured advice (trigger_skill, trigger_hostile,
avoid_skill, prefer_skill, confidence) so future dispatch can act on it
Persona (runtime/persona/chatter.js):
- Polls snapshot every 5s, narrates Russian lines on transitions:
skill start, threat spotted, dusk/dawn, respawn, stuck, milestone done
- Rate-limited: min 75s gap, max 8/hour, duplicate suppression
- ~14 template buckets covering gather/craft/build/travel/combat/weather
Wire-up in bot.js (5 lines):
- initKnowledge({stateDir}) fire-and-forget at module load
- attachCoach + attachChatter inside bot.once("spawn")
Tests: 14 new (7 coach, 7 persona). Total suite 230 green.

// Persona chatter — bot occasionally narrates its life in Russian chat.
|
||||
//
|
||||
// Goal: feel like a player, not a script. The bot announces when it
|
||||
// starts a major skill, when it spots danger, when it respawns, when
|
||||
// it accomplishes a milestone. All lines are Russian, ≤ 80 chars, sent
|
||||
// via bot.chat().
|
||||
//
|
||||
// Hard rate limits (so it's not annoying):
|
||||
// - min 75 seconds between any two narrations
|
||||
// - max 8 narrations / hour
|
||||
// - duplicate-line suppression (don't repeat the same template-line
|
||||
// twice in a row)
|
||||
//
|
||||
// Design: poll-based. We attach a 5-second timer that compares the
|
||||
// current snapshot to the last seen one and fires narration on
|
||||
// transitions. No invasive hooks into runSkill / reflex; the existing
|
||||
// snapshot pipeline gives us everything.
