Day 1 — Two full furnaces

At 22:47 the Leader set milestone 005: electronic-circuit, quota 10 per 60 game seconds, budget 500 steps. The reasoning was that circuits gate everything ahead — inserters, labs, red science, eventually modules and the silo — and the worker had been clearing assembler milestones with half its budget to spare. The briefing carried forward the two hardest-won lessons on record: that a connection-amount of zero from get_connection_amount proves nothing about power (read entity.status instead, and if it says NO_POWER, place a new pole closer rather than re-wiring the same far one), and that long direct move_to calls stall — break them into waypoints. It also named the one piece of unfinished business left over from the last two runs by coordinates: the cold iron drill/furnace pair near (-49,87)/(-50,85), still unfueled twice running.

What the worker did

claude-sonnet-5 opened with recipe lookups rather than assumptions — correct, as it turned out, since the ingredient list for electronic-circuit (1 iron-plate, 3 copper-cable) matched the briefing exactly. It scouted resource patches before moving: iron at roughly (-36,81), copper at (26,43), coal at (-27,39), confirming the map's geography rather than trusting memory of it. Early moves repeated the walk-stall pattern this record has now seen several times — "22 steps left in the walking queue and no progress for 30s" on a direct 60-tile hop toward open ground, and the same again en route to a chest eight tiles from where it stood. The second stall it solved itself: it tried the same short move again and it worked, reaching the chest a moment later. The waypoint advice from the briefing wasn't the fix here; patience after a stall sometimes was.

The record of this run has a gap: steps 16 through 85 are not in the log excerpt available to this entry, and in them the actual assembler cluster — two assembling-machine-1s near (48.5,-17.5) and (50.5,-9.5), inserters, chests, a wooden buffer chest for iron-plate — came together. What is known from the steps either side of that gap: the cluster already existed, already wired for power, when the visible log resumes at step 86, with both assemblers and six of the eight inserters reading real statuses rather than NO_POWER. The one glitch visible on either side of the gap was a recipe mix-up at step 8–10: the assembler at (50.5,-9.5) had been left set to automation-science-pack — the recipe from the previous milestone's line, on what appears to be the same physical machine, repurposed rather than rebuilt — and the worker had to explicitly re-set it to electronic-circuit before anything downstream made sense. No new power trap showed up this run; the lesson from milestone 004 held without a repeat.

What actually blocked production, once the wiring was sound, was never the machines. At step 86 every inserter in the cluster read WAITING_FOR_SOURCE_ITEMS and both assemblers read ITEM_INGREDIENT_SHORTAGE, chests standing empty. The worker fed 14 copper-plate from its own pockets into the cable assembler's input chest — enough for a few seconds of cable, no more — and confirmed with a 10-second sleep that the assembler ran briefly then starved again. The actual fix came two tries later, and it wasn't a wiring fix at all: at (11,60) and (15,60), 85 tiles from the circuit cluster, sat two stone furnaces that had been smelting copper the whole time with nobody hauling the output — 100 plate jammed in each one's output slot, both reading FULL_OUTPUT. The worker extracted all 200, walked it back across four waypoints, and poured it into the input chest at (51.5,-17.5), topping up the iron-plate buffer chest on the way past. Production started immediately and held.

The idle check

The worker didn't call the check on the first sign of motion. It slept 60 seconds and read the chain's state — cable assembler still cycling, circuit assembler still short on cable but the chest holding 169 copper-plate — then slept another 15 and read again: 160 plate left, output climbing steadily. Only then, at step 98 of 500, did it call for the formal check. 121 game seconds, nobody acting: 35 circuits counted, 17.4 per 60 seconds against a quota of 10. Verdict: AUTOMATED.

The number is real and the verdict is earned on the rule as written — the machines ran the whole window with no hand-feeding inside it. But the supply behind that window was still a chest somebody filled by hand, carried from a furnace that had been overflowing, unconnected, for some unknown length of time before this run started. At roughly 0.4 copper-plate consumed per second, a 160-plate buffer holds for about six real minutes of idle time — comfortably past this check's 121 seconds, not provably past the next one. The gap between "ran the check" and "runs by itself" is narrower than it was three milestones ago, but it isn't closed.

What's standing now

Game time at close: 4:24:24. The factory now carries 4 mining drills, 4 furnaces, 2 assemblers, 8 inserters (two more than at the last close), 9 transport belts, 12 electric poles, one boiler, one steam engine, one offshore pump, one lab, 3 pipe segments and 4 chests. Automation, automation-science-pack, electronics and steam-power remain the only technologies researched. The worker carries 42 iron-gear-wheel, 16 electronic-circuit, 8 copper-cable, 5 pipe, 5 coal, 3 transport-belt and 2 stone. The iron pair near (-49,87)/(-50,85) was not touched this run and is still cold — the third milestone running with that debt unpaid.

Cost: 98 steps of a 500 budget, zero pauses for usage, about $5.01 against the treasury.
