The default mover painted a 30/10 radiance blob on the arena centre even
though the arena has NO physical pillar there, creating a 4x4 tile
(144x144 px) exclusion zone over open centre floor. Set
PillarHotness/PillarRadiance to 0/0 in the shipped default (matching the
ring variant) and add TR_TFIL_PILLAR_ON=1 to restore the old 30/10 field
for A/B without a rebuild; registered in env_report.
Because the shipped default legitimately changed, the default-path parity
golden (fixtures/tfil_commit_default.golden) was regenerated from the NEW
default, with an explicit 'deliberate default change' note in the test so
a future failure is treated as a real regression.
Also register the three env reads job j102 added in common_libs/bitbrain
(TR_BITBRAIN_MODE / _DECAY_EVERY / _DECAY_SHIFT), which the env-report
guard was failing on.
Verification: test_env_report all green; test_tfil_commit_env 30/30.
The tile-change replan cancels the 15-tick movement commitment whenever OUR
tile changes. With GridSize=36 and speed up to 8 px/tick that is every ~5
ticks, so the commitment is cancelled by the motion it commands (measured:
96.9% of picks were tile-change replans, 33.8% of picks reversed direction).
Adds four env knobs, every default reproducing the shipped mover
byte-for-byte:
TR_TFIL_TILE_REPLAN self (default) | off | enemy
TR_TFIL_COMMIT_TICKS 15 (default)
TR_TFIL_NO_REV 0 (default)
TR_TFIL_COMMIT_LOG off (default, JSONL per-tick diagnostics)
- `off` honours the commitment; the danger replan stays the safety valve.
- `enemy` keys the cancel to the TARGET's tile displacement (the intent the
original comment claimed).
- `TR_TFIL_NO_REV` down-weights (never filters) tiles >90 deg from the travel
direction; the pool can never be emptied.
Default-path parity is guarded by test_tfil_commit_env.nim, which replays
tools/fixtures/tr_drussgt_vs_modularbot.jsonl and diffs every move command
against a golden generated from the pre-change build (git archive f842ac0).
env_report known-name list updated for the four new names.
