Two bugs the live self-improvement run exposed:
1) Auto-patch was spawned with detached:false, so when supervisor
restarted bot.js (file change after Pi's commit landed on the
auto branch), the auto-patch child was killed mid-way — Pi's
commit lived in the auto branch but never got cherry-picked.
Recovered manually this round via reflog + cherry-pick. Now
detached:true + child.unref() + a per-run log at
state/_auto-patch-last.log so the operator can read Pi's full
output later.
2) Pi's recovery-tunnel-out.test.js was created but not in npm test
script; tests would have stayed unrun forever. Added.
Also commits the Pi-authored skill (eb29591 cherry-picked):
- runtime/skills/recovery-tunnel-out.js (+ test)
- improvements to runtime/actions.js + runtime/skills/explore-far.js
- wired into runtime/skills/index.js
npm test 137/137.

Closes a structural gap: the bot now actually REMEMBERS what it
discovered and what it tried. Two stores live under state/<host>/ and
are wired in automatically.
runtime/world-journal.js
- Append-only JSONL of discovered points (chopped, placed, base,
shelter, farm, dead_end). Indexed by 16-block spatial grid; O(neighbors)
nearest() lookups; 6 h age prune; 10k line ceiling with trim.
- leanestQuadrant({x,z}) reports the quadrant the bot has the FEWEST
markers in — used by explore.far to circle rather than retread.
- summary() exposed for the stuck-incident proposal body.
runtime/scenario-memory.js
- Sliding window of (skillId, situationHash, code, ok, detail) tuples.
- situationHash() is a coarse fingerprint (16x8x16 cell + day/night +
food/hp bucket + inv key set + closest hostile). So "same kind of
place + same kind of state" matches.
- shouldSkip({skillId, situation}) → true after ≥3 failures within 30
min UNLESS a more-recent success in the same situation un-locks it.
- recentTailFor() exposed for the stuck-incident body.
Wiring (runtime/bot.js):
- dispatchAction captures situationHash BEFORE the action runs and
records (skillId, situation, code, ok) after — failures are attributed
to the dispatch-time state, not the partial-effect state.
- worldDelta fields (choppedAt, minedAt, placedAt, baseAt, shelterAt,
plantedAt, harvestedAt, tilledAt) auto-flow into the journal.
- no_target + silent_dig_failure also write dead_end markers.
Scheduler / skills now consume memory:
- reflex.js curriculum reflex calls memory.shouldSkip — if the same
(skill, situation) failed 3+ times recently, auto-converts to a
wander hint so the bot leaves and tries elsewhere.
- explore.far calls journal.leanestQuadrant when multiple cardinal
directions are walkable and prefers the less-explored one.
- gather.logs walks to the nearest known "chopped" bucket within 96
blocks before falling through to findBlock — chunks with confirmed
trees are more likely to yield another.
stuck-incident body now includes journal byKind + last 12 scenario
entries so Pi can write a structural fix, not just a guard clause.
Architecturally: this is the foundation for "bot rewrites itself".
The proposals Pi now receives carry real signal about what was tried
and what's around, instead of a single snapshot in isolation.
10 new tests (world-journal × 5, scenario-memory × 5). npm test 134/134.

When probe-cardinal shows all 4 directions blocked (the bot is in a
1×1 pit, surrounded by leaves, or in a corridor corner), don't just
hold forward+jump — actually dig the block above the bot's head,
jump into the new gap, repeat up to 3 times. Both wander and
explore.far now call escapePit() in this branch.
Observed live: bot fell into a pit at (623,71,106) after first
explore.far and looped wedged-jump→still-wedged→wedged-jump for 60s
before this fix. With escape-pit, the bot now actually breaks out.

Ground-truth finding (diag.physics):
forward N:0.03 E:3.38 S:0 W:3.26 → forward WORKS in unobstructed dirs
jump ΔY=1.25 → jump WORKS (vanilla height)
dig untested (no soft block within 6 of spawn)
So the bot CAN move and jump — the previous "stands still" symptom was
our wander/explore code picking blocked random angles and trusting a
pathfinder that times out on this server's terrain. Each retry just
picked another random direction, often the same blocked one.
- runtime/actions.js wander: probe 4 cardinal yaws for 800ms each,
measure actual Δ, commit to the best one for the remaining budget.
Falls back to "wedged-jump" (forward+jump 2.5s) only when ALL four
cardinals are <0.5 blocks.
- runtime/skills/explore-far.js: same probe-then-go shape, scaled to a
~48-block long walk in the best direction. Replaces the static
NE/SE/SW/NW quadrant rotation that ignored what was actually
walkable.
- runtime/movement-profiles.js: canDig back to true on gather/travel/
flee. The earlier "everything false" defensive default was based on
a wrong hypothesis (silent dig failure) — diag.physics + server-side
inspection (no anti-cheat plugin, spawn-protection=0) showed dig is
fine.
- runtime/compat.test.js: assertions follow profile defaults.
- runtime/skills/diagnose-physics.js: forward probe now tries 4
cardinals and returns trials + bestDir + bestDist so it can be used
to debug "wedged" reports later.
Verified live: bot now actually walks 47 blocks north after
probe.cardinal showed N:2.4 free. First end-to-end real movement on
play.xmatic.team since this session started.
npm test 124/124.

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.
npm test 124/124.
