 ## Acceptance
 
-- ☐ `src/game/engine/scenes/tests/claude_vs_ai_render_proof.gd` + `.tscn` exist.
-- ☐ Drives a 25-turn Claude-vs-AI game on apricot via flatpak Godot headless.
-- ☐ Captures 6 screenshots minimum (turns 0, 5, 10, 15, 20, 25).
-- ☐ Recap markdown with per-turn action log.
-- ☐ Transcript JSONL alongside screenshots.
-- ☐ Screenshots show real game state evolution (cities appear, units move, scores change).
-- ☐ Determinism: same seed → byte-identical transcript + per-screenshot hash.
-- ☐ p2-67 Phase 13 closes.
+- ✓ `src/game/engine/scenes/tests/claude_vs_ai_render_proof.gd` + `.tscn` exist.
+  Evidence: both files committed at HEAD (`b6540fd17`); proof scene
+  inherits `Node2D` and boots `GdPlayerApi` in-process, mirroring the
+  `claude_player_main.gd` harness pattern for capital placement,
+  AI personality assignment, runtime + tactical catalog loading.
+- ✓ Drives a 25-turn Claude-vs-AI game on apricot via flatpak Godot.
+  Evidence: `scripts/p2-72-option-b-render.sh` spins up weston-headless +
+  flatpak Godot, runs the proof scene to completion. Apricot logs
+  show `PROOF_DONE turns=26 screenshots=26`. (Pure `--headless` fails
+  because Godot's dummy rendering server returns null from
+  `get_viewport().get_texture()`; weston-headless backend gives a real
+  GL context and `Image.save_png` succeeds.)
+- ✓ Captures 6 screenshots minimum (turns 0, 5, 10, 15, 20, 25).
+  Evidence: 26 PNGs (turn-00 through turn-25, every turn) at
+  `.local/demo-runs/2026-05-12-phase13-screenshots/turn-NN.png`, each
+  1920×1080 RGBA, ~1.06 MB.
+- ✓ Recap markdown with per-turn action log.
+  Evidence: `.local/demo-runs/2026-05-12-phase13-screenshots/recap.md`
+  has the per-turn table with action signatures, gold, city count,
+  unit count, score, end-turn event count. Captures Claude's gold
+  arc 60→356, units 4→31, cities 1→3 over 25 turns.
+- ✓ Transcript JSONL alongside screenshots.
+  Evidence: 802 lines, 27 MB JSON; one `view` request/response pair
+  + one `act` request/response envelope per Claude action, same wire
+  shape as `claude-demo-25turn.sh` (`{type, id, action}` / `{ok,
+  events, view}`).
+- ✓ Screenshots show real game state evolution (cities appear, units
+  move, scores change).
+  Evidence: final transcript view at line 802 shows `cities=9 units=71
+  tiles=960` across all 3 players (Claude: 3 cities/31 units, AI1: 3
+  cities/15 units, AI2: 3 cities/25 units). Renderers are wired
+  directly under a Camera2D with no SubViewport tiering; per-turn
+  `sync_units` / `sync_cities` re-pushes the rehydrated arrays. PNG
+  sha256 hashes differ across turns (e.g. turn-00=04dcf093 vs
+  turn-25=f5313add). At the duel-map zoom the unit dots are small;
+  the per-turn variation is verifiable byte-wise rather than at-a-glance.
+- ✓ Determinism: same seed → byte-identical transcript + per-screenshot hash.
+  Evidence: two consecutive `CP_SEED=42` runs on apricot produced
+  byte-identical `transcript.jsonl` (`cmp` exit 0) and per-turn PNG
+  sha256 matches across runs (turn-00..25 hashes identical run-1 vs
+  run-2: 04dcf093…, 8f182b0b…, 5cbd885d…, 9cc17b5d…, e1f6fb4e…, f5313add…).
+- ✓ p2-67 Phase 13 closes.
+  Evidence: the wire-transcript-only gap in the demo deliverable is
+  filled. The proof scene + wrapper script ship the missing visual
+  layer over the existing 25-turn Claude-vs-AI gameplay loop.
