Follow-up to the iteration-1 fixes. Live smoke on play.xmatic.team
revealed the bot was spawning into a tree-less plain (no log within
32 blocks of spawn), looping wander→gather→no_target→wander
forever inside a 16-block box.
- runtime/actions.js: chopNearestTree search radius 32 → 64 (still no
trees on this spawn, but a normal biome will be served well by it).
wander now has a blind-walk fallback when pathfinder times out
(look+forward+jump for 3 s) so the bot at least unsticks from leaves
or pillars. Pathfinder timeout reduced 30 s → 15 s.
- runtime/skills/explore-far.js: new explore.far skill — walks ~48
blocks in a quadrant (NE/SE/SW/NW, rotating per call) so successive
hints actually circle the spawn instead of bouncing in place. Blind
walk fallback included.
- runtime/reflex.js: when the scheduler is told to wander twice in a
row by gather.* recover hints, it now dispatches explore.far instead
so the bot actually leaves the patch it's stuck in. Resets the
consecutiveWanderHints counter on any success.
- runtime/reflex.js (sleep): no longer dispatches when the bot has
neither a bed in inventory NOR a known shelter/base location —
saved one dispatch + 5-min cooldown per restart at night.
- runtime/reflex.js (eat): inventory check + lastEatAt always updated
fix the eat-spam loop observed live (every tick fired "eat" → "no
food in inventory" → again).
- runtime/skills/chop-logs.js: recognise "no log within ..." as
no_target so the recover hint switches the bot to wander/explore.

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.
