- make_twin.sh: generates self-contained SacTwin dir in the sample-bots archive (own json/sh identity, own weights dir seeded from a frozen sac_best.zip copy, own round_counter) so RunTraining.java resolves it like any sample bot; re-running resets the twin to the frozen baseline. - src/SAC_LSTM_Bot.nim: SACLSTM_BOT_JSON env overrides the baked-in bot json (loadBotInfo gives json total precedence, #49) so the same binary boots under the twin's name. - sac_train.sh: chunk loop is a while, not for-over-seq — a crash on the FINAL chunk previously fell through ((chunk--);continue on an exhausted seq list) and exited 0 with budget incomplete; observed live vs SacTwin. Readiness dry-run (#54): weighted pool Corners:1,SacTwin:3 picked the twin in 3/4 chunks; all battles counter-checked; deterministic eval parsed; main sac_best.zip/counter untouched by twin (twin counter advanced independently); crash-restart proven end-to-end incl. final-chunk retry.

# make_twin.sh — #54 mirror-twin sparring partner generator.
|
|
#
|
|
# Builds a self-contained `SacTwin` bot dir inside the sample-bots archive so
|
|
# RunTraining.java resolves it like any sample bot ($SAMPLE_BOTS_DIR/<name>).
|
|
# The twin is the SAME binary as SAC_LSTM_Bot but with:
|
|
# - distinct identity (SacTwin.json; SACLSTM_BOT_JSON overrides the baked-in
|
|
# src json — loadBotInfo gives json total precedence over env, #49 lesson)
|
|
# - its OWN weights dir, seeded from a FROZEN copy of weights/sac_best.zip
|
|
# (no checkpoint write races with the main bot)
|
|
# - its OWN round_counter.txt (main liveness guard untouched)
|
|
#
|
|
# Re-running resets the twin to the frozen baseline (reproducible opponent).
|
|
#
|
|
# Usage: ./make_twin.sh [target-archive-dir]
