A Wall Takes the Gun: Two Direct Hits Open a Gap, in the Game and on the Card

Check-in report CI-103. Paul Richeson, treadcore.org; Claude Code (Claude Opus 5.5) as the pair. 6 November 2026, night. Companion records: LAB-REPORT-BRAIN.md section 154; journal 0131.

Abstract

Walls fell to the mortar in the game and to the gun on the card. Now both: a direct shot aimed at a wall takes 45 of a tile's 90 and its neighbour's, so two hits open a gap a tank can drive, and crucible's walls open the same way. Game 9.

I. Intent

Paul: "continue unifiying the motor and the types of direct fire to take down a wall. Treadcore's rules should match crucible. Crucible is made for Cude GPU equivalanet to train and compare with existing gladdiators and ai brinz."

Asked which way to unify the two games' walls, Paul chose: "Treadcore takes direct fire".

II. Decision log

DecisionCause
Only a shot aimed at the wall is takenshots at tanks behind walls keep their refusal; the brain's fire unchanged
The tile and its neighbour along the walltwo hits must open a way a tank can drive
Damage kept per tile, forgotten when it changesa rebuilt wall starts whole
Concrete not hurt by the gunit takes the mortar to crack it
Crucible's gap 3 tilesits tank is 2 wide where this one is 1.5
GAME_VERSION 9a rule change: game 8's census must not count

III. Method

cargo test --workspace; crucible's four builds compiled and the CUDA gauntlet read again under the rule.

IV. Results

See LAB-REPORT-BRAIN.md section 154 for the tests; the card's gauntlet under the rule is recorded in orrery's report Round the Corner.

V. Discussion

Crucible's shells stop on any wall they meet; treadcore's gun is refused unless aimed at one. Crucible's tank fires along its hull with no aim point, so the card cannot ask what a shot was aimed at.

VI. What is not built

The mortar in crucible (its nets have no output for it).

VII. Paul's decisions

Treadcore takes direct fire; crucible's walls all breakable.
