Empty-library run · learned-library run

• 

  Attack refused to swing below 30% health: 277 refusals in one run, 0 swings

  the character fights back when cornered (run 4)

• 

  The copper shortsword was treated as a 14-tile ranged weapon, so the character stabbed air: 0 kills in runs 1 to 5

  first kills; survival suite 3/6 to 11/12

• 

  Scenarios started at spawn, which the Mac run had turned into a house and a mine shaft

  every attempt fights on the same ground

• 

  The escape started at 30% health with a zombie already on top: 6 and 7 deaths in 4 minutes

  low-health scenarios pass (zombie_half_hp 6/6 across S2 and S3)

• 

  The greedy walker cannot take a route that starts by moving away from the target

  nav suite 8/12 to 12/12; tunnel course 0/3 to 3/3

• 

  The first detour course was unsolvable by any walker (stairs faced the wrong way)

  the A/B measures the walker, not the course

• 

  Two benchmark processes drove one game and cancelled each other's skills: a 0/8 run

  a second driver exits with a clear message

• 

  The check wanted the item named Wood; the model held 31 BorealWood and, when told it lacked Wood, crafted a BorealWoodWorkBench on its own

  the model's correct adaptation now counts as a pass

• 

  A task started on a floating island at height 66, above a 29-tile drop

  tasks start on real ground

• 

  The model saved a skill with hard-coded coordinates; reused elsewhere, it walked to trees that were gone

  saved skills carry over to new places

• 

  Scenarios used the Mac character (120 max life, extra gear), which flatters the numbers

  results don't depend on what earlier runs left in the save

• 

  The floating-island fix (an air-gap test) skipped real ground over caves and started tasks underground, invalidating a whole A/B pass

  the A/B restarted on verified ground

• 

  One furnace attempt ran 6918 s of wall clock inside a 180 s skill budget: timeouts count game ticks, and the sim was running far below 60 ticks/s

  a slow game can no longer hide a stuck skill

• 

  Mine_nearest tried ~100 trees one by one behind the same Ebonstone wall it could not dig

  the same spot fails in 2-4 s with 'Ebonstone needs 65% pickaxe power' instead of hours

• 

  The containers spent their CPU drawing frames nobody sees: ~21 ticks/s with the agent's own code at 0.4 s of CPU per 78 s skill

  60 ticks/s headless, ~500 at speed 8; the same 7-tree task takes the same 1639 ticks and ends on the same tile at 1x and 4x, in 3.5 s instead of 78 s

• 

  One of three game instances crashed and its worker failed 27 jobs in a second as unreachable, which published a 3/30 suite

  a crash costs time, not a wrong number on the page

• 

  In a snow start the model asked for a WorkBench three times; craft only said 'Wood 0/10' while it held 35 BorealWood

  workbench passes; on a fresh world per task the fresh pass got 5/8 and the learned pass 6/7, wood to door all on the first attempt

• 

  A reused library skill aborted a furnace program for being 3 stone short of the check from the task it was learned on (the furnace needs 20, it had 27)

  reused skills chain: hammer reused three saved skills in one program

• 

  Fast-forward made fights harder: with the world running between calls, every second the agent spends deciding costs 4 seconds of game, and the flier scenario fell from 3/3 at 1x to 1/3 at 4x

  headless 1x survival suite 16/18, the best so far (15/18 rendered)

• 

  Task patches 120 tiles apart while tree search reaches 180 each way, and the model cut 30 trees a call: the fifth task found no tree in reach

  chair_table, which failed in every earlier run, passed first try in both passes

• 

  On a steep hillside no flat 3-tile floor was in reach, so the work bench could not be placed anywhere the character walked

  both failing hillside spots now craft the door

• 

  A tunnel stopped at grass with a tree on it ('did not break: something on top'); Terraria won't break a block under a tree

  the same tunnel digs through (15 tiles)

• 

  At 35 health with zombies 3 tiles away on both sides, dig_in (about 6 s of digging) died every time; the scenario sat at 1/3

  first live run (Mac showcase): flee escaped, 25 tiles, nothing within 18; then the zombies caught up during the 6 s dig_in and it died. Next: run further before digging

• 

  Flee stopped at 18 tiles clear; a zombie walks ~5 tiles/s and dig_in takes ~7 s, so they reached the hole mid-dig (0/3, same as the Mac showcase). Once a bunker healed to its target, the work step mined out with zombies still on the roof

  two_zombies_low_night 0/3 -> 3/3, then 2/3 on the next build (5/6); whole suite 14/18 -> 15/18 -> 16/18

• 

  Craft reported ingredients for one batch ('CopperOre 0/3') after making 1 of 3 bars, so nothing said 9 ore were needed

  the hint shows up in the night3 log, and gpt-oss still mined 2. It keeps reading the ore count as a bar count: wording alone doesn't fix copper_bars

• 

  The model gave up: three attempts of 'cannot_smelt_bars: wait 0', which the bench scored like any other failed program

  no give-up programs in the night3 or night4 passes

• 

  No Furnace could go down at the bottom of a 2-wide shaft. Three bugs stacked: levelling started 2 columns out (the column beside you is the wall), it first walked toward flat ground up the shaft and levelled mid-jump 25 rows up, and every pickup hop made the next mine check reach in mid-air

  station suite 9/12 -> 12/12 (shaft 0/3 -> 3/3); nav 4/4 and survival 16/18 on the same build
