…oling) - 116 open-source classic Robocode bots imported to CodeClash-ai/RoboCode human/robocode/* branches (source of truth, not committed here) from ~30 repos: shipped sample bots + mgalushka Super* variants; the full RoboWiki/PEZ collection (micro/mini/nano/femto + Marshmallow/GF1/Swiffer); flat multi-file bots (Mb2, BerendBotje, MaximBot, TheCarver, BobTheBuilder, StarterBot, npcomplete); flattened subpackage bots (ur4no, kokomo); single-file DrussGT/HawkOnFire (strong top rungs); and ~35 more from a broad GitHub sweep. All copy-in (0 reimplementations) -- verbatim, only repackaged to the arena package + main class renamed to MyTank (helpers flattened where needed). yngwie/chomsky skipped (unresolvable external deps). - Each of the 116 verified to COMPILE and play a real battle in the arena image (stage 2, 116/116). - Provenance: every port file carries a source-URL/author/license header; scripts/ladder/SOURCES.md is the committed manifest (slug -> GitHub URL). See stamp_sources.py. - Fix arena description: it mislabeled itself Tank Royale but the engine is classic Robocode. - make_robocode.yaml: round-robin (100 rounds, ~2h local at -w6) for Elo; README note. - scripts/ladder/: build tooling (copy-in porting guide, structural validator, compile+battle smoke, push script, provenance stamper, reference bot); ports/ regenerated, not committed.
`ladder make` set the per-player name to the raw branch_init (e.g. `human/robocode/walls`), which the RoboCode arena turns into an on-disk dir, a Java package via `sed s/custom/<name>/`, and a robot-selector token. Slashes broke the sed (terminating the s/// command) and produced invalid robot names, so battles loaded 0 robots and get_results crashed on max() of an empty score dict. Sanitizing to `robocode_<bot>` still failed: RoboCode reserves the `robocode` package namespace for its engine, so its robot classloader refuses any robot whose package starts with it (ClassNotFoundException at battle time). Add `_player_slug()` (shared by make + run) that strips the `human/` prefix and a leading path segment equal to the game name, yielding a bare `<bot>` package (e.g. `human/robocode/walls` -> `walls`). Non-RoboCode branches (`human/<author>/<bot>`, `human/<bot>`) are unaffected -- their leading segment never matches the game name, so slugs are identical to before. Bump make_robocode.yaml sims_per_round 100 -> 300 for lower Elo variance (~41s/pair solo, ~25s/pair throughput under -w 6; still far under the 5-min/pair budget) and refresh the cost comment with measured numbers.

The round-robin only needs per-battle scores to fit Elo; recording every sim wrote ~8.7MB of compressed replay XML per pair (~59GB over 6670 pairs, risking disk exhaustion mid-run) and pinned a gzip core on each log copy. Scores come from results_*.txt, which is unaffected. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
