Three closures of remaining PRD follow-ups, one merge:
1. Reflex scheduler now drives behaviour from the curriculum.
- reflex.js: replaced ad-hoc techTreeReflex + autonomousReflex with
curriculumReflex that dispatches the skill suggested by
snapshot.curriculum.plan via runSkill. Per-skill backoff for
missing_tool / missing_material / no_target / no_food_source /
unsupported_version. recover() hint with `{hint:"wander"}` swaps
the next tick to wander for 60 s.
- Chain is now: defend > eat > sleep > curriculum > idle.
- reflex.test.js: 11 new tests covering busy/disconnected,
defend/eat preemption, dispatch by id, unknown-skill fallback,
per-skill + wander-hint backoffs, onComplete updating backoff.
2. Pi escalation for ADDRESSED_BANTER with hard rate limit.
- bot.js: when generateReply returns {escalate:true}, spawn askPi
with bot state + last 5 lines from that speaker (redacted via
chatMemory). Reply capped at 200 chars, sent as one chat line.
- Rate cap: 6 calls/hour, 90 s min gap. Suppressed escalations
log once and silently drop.
3. Phase 4 substrate.
- runtime/locations.js: atomic JSON store
(state/<host>/locations.json) with setLocation / getLocation /
nearestLocation / removeLocation; 6 tests.
- runtime/base-site.js: scoreCurrentPosition(bot) + pure scoreSite
bundle (wood / stone / water / flatness / no-players /
no-foreign-builds, owned-blocks excluded from claim penalty);
6 tests.
- runtime/skills/choose-base.js: village.choose-base skill — scores
the current spot, writes locations.base if score ≥ 8, otherwise
returns code:"too_weak" with a wander recover hint.
- curriculum.js: new final milestone village.base-site fires
village.choose-base until a base location exists.
- bot.js: stamps snapshot.locations from listLocations() each tick
so the curriculum can read it without coupling to disk.
docs/runtime.md updated with three new sections.
npm test now 116/116.

Two safety rails on the unattended self-improvement loop:
1. scripts/edit-scope.js + .test.js: pure helpers that parse
`editScope: [...]` out of a proposal frontmatter (the field Phase 6
started writing) and validate a list of changed files against it.
13 tests covering null/missing/malformed frontmatter, directory
prefix matching, exact-file matching, default-scope fallback.
2. scripts/auto-patch.js:
- reads editScope from the proposal (falls back to ["runtime/"])
- injects the allowed paths into the Pi prompt so Pi knows the
boundaries up front
- validates the diff against scope + auto-allows any
runtime/**/*.test.js files Pi added
- runs `npm test` on the patched branch BEFORE cherry-picking;
refuses to land a patch that breaks the suite
Closes the "Smoke checks run before applying patch" item from
plans/autonomous-survival-bot-prd.md §7 Phase 6. npm test now 92/92.

Phase 7 of plans/autonomous-survival-bot-prd.md. Five small modules
that close the recurring "shared state" and "version-pinned list"
failure modes the PRD flags in §7 and §5.4.
New:
- runtime/movement-profiles.js: named profiles (GATHER, TRAVEL, FLEE,
BUILD, RETURN_TO_BASE) as pure descriptors via PROFILE_DEFAULTS,
plus applyProfile(profile, bot) that hands a fresh Movements to
pathfinder. Avoids the "flee left canDig=false on the shared
Movements, next chop got stuck in canopy" regression.
- runtime/owned-blocks.js: JSONL ledger of blocks this bot placed/
removed (state/<host>/owned-blocks.jsonl); isOwned({x,y,z}) for
O(1) lookups; ensureDir() makes the parent dir lazily.
- runtime/claim-avoidance.js: classifyArea({blocks, isOwned}) returns
player_build / natural_or_owned / insufficient_data based on
man-made block density vs ownership ratio; shouldAvoid(area) helper.
Designed for gather/place skills to call before touching contested
area.
- runtime/skills/compat.test.js: runs runtime/skills/groups.js against
real minecraft-data registries for 1.18.2, 1.20.4, 1.21.5; spot-
checks that pale_oak_log only appears on 1.21+ etc.
- runtime/compat.test.js: 10 tests covering movement descriptors,
isManMadeBlockName, classifyArea, owned-blocks markPlaced/dedup/
isOwned/markRemoved.
npm test now 79/79.

Phase 6 of plans/autonomous-survival-bot-prd.md. Expand the
self-improvement loop so the bot can spot and report no-progress
stagnation, not just exception-class failures.
New:
- runtime/stuck-incident.js: detector fires a structured proposal when
the same noProgressReason persists past 5 min (cooldown 30 min).
Body includes runtimeState, milestone, suggested skill, slim
snapshot, last action result, per-skill success/failure metrics
and a forbidden-paths list. Pure module — caller (bot.js) writes
the proposal.
- runtime/skill-metrics.js: in-memory per-skill ok/fail counters
surfaced on snapshot.skillMetrics for the TUI and the incident
body.
- runtime/stuck-incident.test.js: 6 tests covering null reason,
threshold gating, cooldown, reason change resetting the timer,
body composition and metrics snapshot.
Wiring:
- runtime/state-store.js: writeProposal accepts {editScope: string[]}
and persists it in the frontmatter; readProposalEditScope() reads
it back so future auto-patch.js can refuse cherry-picks that touch
other areas.
- runtime/bot.js: tick() invokes the stuck detector each tick,
records skill ok/fail via skillMetrics, stamps snapshot.skillMetrics
and writes the stuck proposal via writeProposal({editScope}).
dispatchAction now records into skillMetrics for both the
resolved-result and the exception path.
npm test now 46/46.

Phase 5 of plans/autonomous-survival-bot-prd.md. Make the bot feel
present in chat without ever becoming a command executor.
New: runtime/social/
- intent.js: classifyIntent({text, botName}) returns one of GREETING /
STATUS_QUESTION / ADDRESSED_BANTER / COMMAND_LIKE / UNSAFE_REQUEST /
AMBIENT. Unicode-aware word boundaries so cyrillic + latin both work
("Привет всем" → GREETING, "build me a tower" → AMBIENT unless
addressed).
- reply.js: generateReply({intent, speaker, snapshot, diaryTail}) →
short templated response, or {send: null, escalate: true} for the
caller to decide whether to spend Pi tokens.
- memory.js: createChatMemory() — per-speaker LRU buffer of recent
lines; redacts password / api_key / JWT-shaped tokens at append
time, so the buffer can be safely fed back into any future prompt.
- social.test.js: 12 tests (intent edges, memory eviction, redaction,
reply routing). npm test now 40/40.
state-store.js additions:
- readDiaryTail(n) — reads the last N lines of today's diary; used by
status replies.
- writeEscalation({from, request, whyUnsure, wouldHave}) /
listEscalations() — JSONL log under state/<host>/escalations.jsonl
for UNSAFE_REQUEST classifications and future operator review.
bot.js: handleChat() now routes through social/intent + social/reply
(replacing the Phase-0 inline regexes), records every line into
chatMemory, and writes an escalation when classifyIntent returns
UNSAFE_REQUEST. Command-like notice + dialog-only behaviour from
Phase 0 are preserved.

Phase 3 of plans/autonomous-survival-bot-prd.md. Gives the bot a
deterministic path from empty inventory through stone-tier tools and
basic storage, without an LLM call per tick.
New:
- runtime/curriculum.js: ordered milestone chooser
(wood.16 → wood.planks-and-sticks → wood.tools → stone.32 →
stone.tools → food.basic → storage.chest → shelter.torch). Each
milestone exposes isDone(inventory, snapshot) and suggest() returning
a { skillId } plan the scheduler can dispatch via runSkill. isDone
uses "stage reached" escapes so progress is monotonic — crafting
planks doesn't bounce the chooser back to "gather 16 logs".
- runtime/skills/gather-stone.js: gather.stone with pickaxe-required
precondition, blacklist on failed paths, registry-aware matching
(stone / cobblestone / deepslate / cobbled_deepslate / andesite /
diorite / granite).
- runtime/skills/craft.js: factory + concrete skills for craft.planks,
craft.sticks, craft.wooden-axe/-pickaxe/-sword, craft.stone-axe/
-pickaxe/-sword, craft.furnace, craft.chest, craft.torch (torch
requires coal or charcoal preflight).
Tests:
- runtime/curriculum.test.js: 14 tests covering chooser ordering,
per-milestone skill suggestion, inventoryFull threshold, monotonic
advancement across stage transitions.
- npm test now runs the full suite: 28/28 passing.
Wiring:
- runtime/bot.js: lastSnapshot.curriculum carries the next milestone
+ suggested skill on every tick; lastSnapshot.currentMilestone
prefers the curriculum title over the planner.md line.
- tui/tui.tsx: milestone line shows the curriculum's suggested skill
and an [inventory full] flag when isInventoryFull fires.
Reflex.js still calls actions.js directly; wiring the scheduler to
runSkill(plan.skillId, …) lands in Phase 4.

Phase 2 of plans/autonomous-survival-bot-prd.md. Establishes the
composable skill contract from PRD §5.2 and ports three reference
skills so future phases can layer survival behaviour on top instead of
adding more ad-hoc branches to reflex.js.
New: runtime/skills/
- index.js: skill registry + runSkill(id, ctx, args) wrapper. Enforces
preconditions, hard timeout, normalises {ok, code, detail, worldDelta}
on every result, runs validate() and calls recover() on failure.
Stable failure codes live in RUNNER_CODES (unknown_skill,
precondition_failed, timeout, threw, validation_failed, done).
- groups.js: registry-derived item/block sets — logs/planks/sticks/beds
derived by suffix; foods intersects a curated allowlist with the live
bot.registry; axes/pickaxes/swords scoped to whatever the connected
server's item table actually ships. Empty set instead of throwing on
missing registry, so skills can emit code:"unsupported_version".
- chop-logs.js: gather.logs reference skill (wraps chopNearestTree).
- eat.js: survive.eat (wraps eatBestFood, preconditions check carrying
edible food from the registry-derived set).
- wander.js: explore.wander (wraps wander).
- contract.test.js + groups.test.js: 14 tests covering precondition
gating, timeout firing recover(), execute exceptions, validate
flipping ok→false, dynamic group filtering across mock registries.
package.json: `npm test` runs the new contract + groups suites.
docs/runtime.md: documents the skill contract, runner, dynamic groups
and the reference skills.
Reflex.js still calls actions.js directly — wiring the scheduler to
runSkill() lands in later phases when the survival curriculum kicks in.

User report 2026-05-25: launched 'npm run bot' fresh, MC server kicked
every login with "Игрок с данным никнеймом уже играет на сервере" and
the bot fell into a perpetual reconnect-then-kicked loop. Root cause:
a smoke-test supervisor from an earlier shell was still running in the
background, holding the pepa_bot session open. Two supervisors racing
on the same nickname is undefined behaviour from the server's side and
results in this exact failure mode.
Changes:
runtime/supervisor.js — acquires state/<host>/supervisor.pid before
spawning the child. If another supervisor is alive (kill -0 check), the
new one exits with a clear message telling the operator how to recover.
On SIGINT/SIGTERM/exit the lock is released; stale pidfiles are detected
when the recorded PID is no longer alive.
scripts/stop.sh — emergency cleanup helper:
- kills any supervisor or bot.js processes matching this repo
- removes pidfile + bot.sock
- reminds the operator to wait ~30s for the MC server to drop the old
session before re-launching
package.json — new `npm run stop` script.
Smoke-tested:
- first 'node runtime/supervisor.js' acquires lock, writes pid
- second call refuses with diagnostic message
- first SIGTERM ⇒ pidfile removed automatically

Closes the self-improvement loop end-to-end:
reflex fails 3× → proposal file → operator approves in TUI →
`npm run propose:apply <file>` spawns Pi on a feature branch →
Pi commits the patch → supervisor watches runtime/*.js and
restarts the child on change.
runtime/state-store.js — atomic current-task.json writes, daily diary
append, proposals/ + proposals/approved/ helpers.
runtime/bot.js:
- ctx.dispatch writes current-task.json on start and updates it on
completion / failure / throw.
- failure tracker: 3 consecutive same-label failures → writeProposal()
with the snapshot, labels, and a suggested-next-step section.
30-min cooldown prevents proposal spam.
- on startup, surfaces resume info (previous task + pending proposal
count); on death, clears current-task.json + writes diary line.
- new IPC commands: PROPOSAL_LATEST returns the newest pending
proposal body; PROPOSAL_APPROVE moves it to proposals/approved/.
tui/tui.tsx — status bar shows `[proposals N, press y]` badge when
bot.pendingProposals > 0. Hotkey 'y' opens the proposal panel; 'y'
approves, 'n'/Esc closes.
scripts/propose-apply.js — given an approved proposal filename, creates
a `feat/proposal-<slug>` branch and spawns `pi -p` with the proposal
+ repo-conventions prompt. Refuses on dirty tree. No auto-push, no
auto-merge — operator reviews the diff and decides.
runtime/supervisor.js — forks bot.js as a child, watches runtime/*.js,
restarts on file change or on child exit code 42. Rate-limited at 5
restarts/minute. SIGINT/SIGTERM forward cleanly. `npm run bot` now
goes through the supervisor; `npm run bot:bare` skips it.
Smoke-tested: supervisor spawned, bot connected to MC, spawned at
expected coords, diary line written, state cleanup on SIGTERM correct.

* fix(mindcraft-skills): hard timeout on every skill call
mc_avoid_enemies (and 7 other tools) wrapped only in safeCall without a
withTimeout. When mindcraft's underlying pathfinder/pvp goal couldn't be
satisfied, the call never resolved — the Pi tick loop blocked forever.
Observed live: mc_avoid_enemies pending >10 minutes after one mc_observe.
safeCall now takes timeoutMs (default 30s) and wraps withTimeout itself,
so every tool gets a hard ceiling. Per-tool overrides:
- goToPosition / goToNearestBlock: 120s / 90s (unchanged from before)
- defendSelf / avoidEnemies: 45s
- stay: secs*1000 + 10s
- craft / consume / pickup / place: 30s
- equip: 15s
collectBlock still uses its bespoke per-iter 75s loop.

* feat(runtime): script-driven reflex daemon + Ink TUI dashboard
Pure-Pi runtime had three failure modes in practice:
- slow: 20-60s per decision because LLM was in the hot path
- expensive: every tick (defend, eat, idle) paid for a reasoning pass
- invisible: required tmux capture-pane to know what the bot was doing
New runtime/ layer is a long-running Node daemon that owns the MC
connection, ticks a priority-ordered reflex chain (defend > eat > sleep
> idle) with NO LLM in the hot path, and exposes status + commands over
a Unix-socket IPC. tui/ is an Ink dashboard that attaches over IPC and
can detach freely — multiple TUI clients can connect at once.
Pi/Codex are still available, but as on-demand escalation: TUI hotkey
'a' spawns `pi -p "<prompt>"` as a subprocess and streams stdout into
the dashboard. The self-improvement loop (proposals → operator approval
→ Pi-driven patch → hot reload) is documented in docs/runtime.md but
not yet wired.
Reflex bodies are stubs today — they log decisions but don't drive
Mineflayer actions yet. The priority chain, IPC contract, and TUI are
fully working; subsequent commits will fill in defend/eat/sleep bodies
and wire automatic escalation.
Run with `npm run bot` + `npm run tui`. Pi-only fallback stays at
`npm run agent`.

The bot was acting blind: it knew its own coordinates but nothing about
what was around it. mc_goto's over-strict safety guards refused every
real path. mc_dig was too low-level to drive a coherent farming loop.
The result: 4+ hours of "trying" with zero physical achievement.
This commit reframes the bridge around a perceive→decide→act loop using
proven primitives from Mindcraft (github.com/kolbytn/mindcraft, MIT —
LICENSE-MINDCRAFT vendored beside the library files).
Changes:
- extensions/lib/ (new, vendored from Mindcraft with attribution)
- world.js (431 LoC) — 21 perception functions: getNearbyBlockTypes,
getNearbyEntities, getInventoryCounts, getNearestBlock, getPosition,
getBiomeName, etc.
- skills.js (2093 LoC) — 30+ action primitives: collectBlock, placeBlock,
goToPosition, goToNearestBlock, craftRecipe, equip, consume,
defendSelf, avoidEnemies, pickupNearbyItems, stay, etc.
- mcdata.js (~600 LoC) — Mindcraft's mc-data adapter. Imports patched
to local paths; mineflayer-auto-eat removed (our installed 5.x has
a divergent API; skills.consume() falls back to bot.consume()).
Added attachPluginsAndInit(bot) export so mineflayer-bridge.ts can
wire plugins onto its externally-created bot.
- settings.js — minimal stub with farmer-bot defaults.
- extensions/mindcraft-skills.ts (new, 406 LoC) — Pi extension registering
15 high-level tools on top of the vendored library:
- Perception: mc_observe, mc_inventory, mc_nearby_blocks, mc_nearby_entities
- Action: mc_collect_block, mc_place_block, mc_go_to, mc_go_to_block,
mc_craft, mc_equip, mc_consume, mc_defend_self, mc_avoid_enemies,
mc_stay, mc_pickup_nearby
ES modules from extensions/lib/ are loaded via dynamic import() at
extension init so the cross-extension require()-race resolves cleanly.
- extensions/mineflayer-bridge.ts
- Expose the live Mineflayer bot on globalThis.__pepaPiBot so the
mindcraft-skills extension can use it (set on connect, cleared on
error/end/manual disconnect).
- Call attachPluginsAndInit(nextBot) right after createBot to load
pathfinder, pvp, collectblock, armorManager and prime
minecraft-data once login completes.
- package.json — new runtime deps: minecraft-data, vec3,
mineflayer-pvp, prismarine-item.
- AGENTS.md — new "Perception → decision → action" section before
"Your tools right now" with full tool catalog and a deprecation
note for the broken mc_goto / mc_build_pyramid_5x5 / low-level
mc_dig from the old bridge.
Smoke test (medium thinking): bot called mc_observe and received a
real JSON snapshot — nearbyBlocks listed coal_ore, oak_log, water,
sand; nearbyEntityTypes listed creeper, zombie, pillager, skeleton.
The bot can finally see what it could not see this morning.
