pepa-pi-bot/runtime/goal/storyline.js

// Storyline — canonical Minecraft survival quest the bot lives inside.
//
// Why this exists (rationale, 2026-05-27 evening):
//
// After v0.3.0 went live the bot got stuck in a loop:
//   acquire-food (fail: no nearby food) → explore.far → pillar-up (fail) → repeat
//
// Manifesto + LLM advisor both correctly say "you need food" but
// neither expresses *what concretely to do next*: scout 64 blocks N
// for cows; chop oak nearby; place a crafting table. The bot has no
// narrative arc, just a priority ranking of unsatisfied needs.
//
// Storyline fixes this by laying down the classic vanilla Minecraft
// survival path as an ordered list of *concrete* steps. Each step
// owns:
//   - id, title, narration_ru (chat-friendly Russian one-liner)
//   - completed(snapshot) → bool — detects if this step's goal has
//     been achieved purely from snapshot
//   - suggestSkill(snapshot) → { skillId, args? } | null — the
//     concrete next dispatch for the step's pursuit
//   - emergencyPause(snapshot) → bool — true if a higher-priority
//     condition (low HP near hostile, lava under foot, etc.) means we
//     should drop story progression for a tick
//
// The runtime/goal/state.js picker walks the list and returns the
// first non-completed step, with its suggestSkill. That feeds into:
//   - reflex.js dispatch picking (storyline overrides curriculum, but
//     manifesto L0 alive emergencies still win)
//   - persona/chatter.js — narrates step start in MC chat
//   - coach/fast-advisor.js — user prompt includes current step so
//     the LLM advice is anchored in the actual narrative
//   - postmortem / reflect — the LLM can flag missing skills using
//     the current step as concrete context
//
// Storyline order mirrors manifesto levels but is more *operational*:
// where manifesto says "L2 tools_wood satisfied if you have a wood
// pickaxe", storyline says "step first_tools: place crafting table,
// craft wooden pickaxe + axe + sword, with these specific subgoals."
