The repo's first multi-opponent gun measurement. Adds tools/ab/gauntlet_run.sh (per-opponent A/B over the legacy roster, subject = frozen ModularBot), tools/ab/gauntlet_analyze.py (paired per-opponent deltas, cross-opponent sign test, style split, MDE) and the arm/opponent fixtures. Result: BitBrain does NOT generalize beyond DrussGT. 32 opponents x 2 arms x 3 runs x 5 rounds = 192 battles / 960 rounds, 0 failed, 0 retries: damage/run 214.5 (pattern) vs 210.9 (bb), sign-flip p=0.53; round wins 237/480 vs 239/480, p=0.91. Sign test: bb better on 13/32 opponents (damage). The DrussGT-only penalty does not carry. The owner's 'killer vs regular movers' sub-claim is not supported: regular bucket +1.3 dmg/run vs dodgers -0.2 (MW p=0.85), and the measured movement predictability does not correlate with the delta.

# gauntlet_run.sh — run a PER-ADVERSARY A/B gauntlet of N arms against MANY
|
||
# legacy opponents (the generalization test for the gun claims that have, until
|
||
# now, always been measured against the single opponent DrussGT).
|
||
#
|
||
# tools/ab/gauntlet_run.sh \
|
||
# --arms tools/ab/arms_gauntlet.txt \
|
||
# --opponents tools/ab/opponents_gauntlet.txt \
|
||
# --runs 3 --rounds 3 --conc 5 --outdir /tmp/ab/j117_gauntlet
|
||
#
|
||
# Difference from ab_run.sh: ab_run.sh hard-wires exactly ONE adversary
|
||
# (DrussGT, via run_bridge_battle's legacy default subject). Here the SUBJECT
|
||
# is the frozen ModularBot itself (so the capture's `subject event counts` are
|
||
# ModularBot's own fire/hit/taken counts and `firstPlaces` is ModularBot's
|
||
# name-based round wins) and the ADVERSARY iterates over a list of legacy
|
||
# champ bot dirs from tools/robocode_shim/robots.json.
|
||
#
|
||
# For every (opponent, arm, run) it launches a real Tank Royale battle through
|
||
# tools/robocode_shim/run_bridge_battle.sh, each in its own process group with
|
||
# ephemeral ports and an isolated classic data dir.
|
||
#
|
||
# Arm file format (same as ab_run.sh):
|
||
# name | ENV_VAR=value ENV_VAR2=value2 | optional label
|
||
#
|
||
# Opponent file format (one per line):
|
||
# /tmp/tr_bots/<Name> | style-label # or a bare Name (=> /tmp/tr_bots/)
|
||
# Blank lines and #-comments ignored.
|
||
#
|
||
# Output layout (what gauntlet_analyze.py reads):
|
||
# <outdir>/session.json
|
||
# <outdir>/<opponent>/<arm>/run<N>.jsonl tick capture
|
||
# <outdir>/<opponent>/<arm>/run<N>.jsonl.rounds.json round boundaries

# <outdir>/<opponent>/<arm>/run<N>.jsonl.results.json cumulative scores

# <outdir>/<opponent>/<arm>/run<N>.bot.stdout.log ModularBot env
|
||
#
|

# Cleanup: every job runs in its own process group (setsid); on EXIT/INT/TERM

# this script SIGTERMs/SIGKILLs those groups and pkills anything referencing
|
||
# this session's outdir, so a Ctrl-C leaves no orphan battles.
