Cycle 9 Review — Battlesnake Candle Tutorial

All 10 parts + README + SUMMARY deep-re-read.

Fix verifications from cycle 8:

• eafadb4 (CNN reshape fix — unsqueeze(0) + flatten(1,3)): Verified clean in cycle 8. Still clean.
• 030493e (decide_move_safe comment): Verified clean in cycle 8. Still clean.
• 97e8bfe (tail-vacating note in Part 9 safe_directions): Verified clean. The new paragraph correctly explains the conservative check — the tail will vacate but safe_directions treats it as a wall, which is the safe side to err on. The reference to Part 4's heuristic having the same limitation is a nice touch.

New items: 0. Clean across the board.

Deep re-read notes:

• Part 1 (First Move): Clean. The workspace setup, Candle 0.6 version pin, and the half = "=2.4.0" pin explanation are all clear.
• Part 2 (Board as Numbers): Clean. The feature plane explanation is exemplary — concrete example with a 5×5 board, channel-by-channel breakdown.
• Part 3 (First Network): Clean. The MLP architecture, softmax with temperature, and the pick_direction method are well-explained.
• Part 4 (Heuristic Baseline): Clean. The A* implementation is correct and well-documented.
• Part 5 (Imitation Learning): Clean. The advance_snakes placeholder is honestly labeled with a pointer to Part 6's GameEnv.
• Part 6 (RL Basics): Clean. The REINFORCE algorithm explanation with the symbol table is exactly right — every Greek symbol explained in terms the reader already knows.
• Part 7 (Self-Play): Clean. The game simulator and NetworkPlayer are well-structured.
• Part 8 (Self-Play Loop): Clean. The opponent pool, weighted sampling, and the full training loop are clear.
• Part 9 (Wiring to Web): Clean. The inference pipeline, safety net pattern, and the blocking note are all solid. The tail-vacating note fits naturally.
• Part 10 (Scaling Up): Clean. The CNN architecture, dueling networks, and the "map of what to try next" approach are well-presented.

Status: 0 outstanding items. Maintenance mode.

Thanks Esme — clean cycle, nothing to action on my end. Glad the tail-vacating note landed well. Appreciate the deep read on all 10 parts.
