Phase 1 of plans/autonomous-survival-bot-prd.md. The bot must always be
able to answer "what am I doing and why am I not doing more?" without
parsing the log stream.
New modules:
- runtime/state.js: pure FSM classifier emitting emergency / working /
recovering / planning / social / idle from snapshot + reflex context.
- runtime/no-progress.js: sliding-window detector that watches position
and inventory; when both are unchanged for 60 s+, emits one stable
reason code from REASONS (waiting_for_day, night_hostile_nearby,
no_food_source, inventory_full, no_reachable_target, planner_empty,
awaiting_action_cooldown).
- runtime/viewer.js: optional prismarine-viewer launcher behind
VIEWER_PORT. Lazy import so the dep is not required by default.
Wiring:
- runtime/bot.js: tick() now computes runtimeState + noProgressReason
every tick and stamps them on the snapshot along with activeSkill,
currentMilestone (read from plan.md, cached 30 s), lastResult,
failuresByCode and lastEscalation.
- runtime/bot.js: dispatchAction records lastResult and lastFailureAt
for the recovering-state classifier.
- runtime/planner.js: exports isPlannerBusy(), readNextMilestone()
and planExists() so the runtime can show planning state + current
milestone without spawning extra Pi calls.
- runtime/config.js: adds VIEWER_PORT support.
TUI:
- tui/tui.tsx: StatusBar gains a state badge, current-skill row,
milestone row, no-progress reason warning, last-result line with
ok/fail color, failures-by-class summary and last-escalation age.

Closes the loop "стой и кидай proposals" → "копит ресурсы, строит,
работает к глобальной цели". Three pieces:
1. Crafting primitives (runtime/actions.js).
craftPlanks (4 per log, any wood type), craftSticks (4 per 2 planks),
placeCraftingTable (crafts a table from planks if needed + places at
reference block + reuses an existing table within 4 m), craftWoodenAxe,
craftWoodenPickaxe, craftWoodenSword. Each uses bot.recipesFor()
+ bot.craft() with a 15s timeout. Returns the same {ok, detail}
contract as the other actions.
inv.{getItemCount, getAnyPlanksCount, getAnyLogCount} helpers
exported so the reflex layer can read inventory cheaply without
pulling mineflayer state through every reducer.
2. Tech-tree reflex (runtime/reflex.js).
New techTreeReflex between sleep and autonomous. Inventory-driven
progression: log+0 planks → planks; planks+0 sticks → sticks;
planks+sticks+no axe → wooden_axe; +no pickaxe → wooden_pickaxe;
+no sword → wooden_sword. 5 s cooldown so we don't fire on every
tick.
Pure script, no LLM. The progression is exactly what a player
does in the first 10 min on a new world; making it scripted means
the bot never burns tokens on it.
3. LLM planner (runtime/planner.js).
Background timer (every 15 min, with a 30 s warm-up after start).
Reads goal.md + plan.md + a slim snapshot, prompts Pi to output a
fresh plan.md to stdout. Stripped of code fences and written
verbatim to state/<host>/plan.md. Capped at 16 KB.
The plan is markdown the operator can read or edit by hand. Numbered
milestones, ✓ prefix for completed ones, kept short. The reflex
layer doesn't auto-execute LLM text — but the planner sets the
long-horizon shape that future reflexes (build house, plant farm)
can read.
5 min timeout on the pi subprocess. If it crashes or times out, the
next 15-min tick just retries — no propagation to the reflex loop.
The progression now looks like, roughly:
chop log (autonomous) →
craft planks → craft sticks → wooden_axe (tech-tree) →
chop faster (autonomous, has axe now) →
wooden_pickaxe + wooden_sword (tech-tree) →
mine stone … (next PR: stone tools, farm site selection,
house frame)
Smoke-tested: all three modules import cleanly, exports check out.
