   `turn_processor.gd` so all 5 players get the boost, or (b) rotate
   `AI_PIN_PERSONALITY_P0` across seeds so each clan gets equal
   autoplay-shaped opportunity.
+
+  **2026-05-17 cycle 5**: chose option (b). Implemented per-seed clan
+  rotation directly in `tools/autoplay-batch.sh::_run_local`: reads
+  `AI_PIN_PERSONALITY_P{0..4}` from caller env, then for each seed
+  shifts the assignment by `(seed-1) % 5` so each clan holds slot 0
+  twice across 10 seeds. Pinning propagates through `--env=` flatpak
+  flags (previously only the singular `AI_PIN_PERSONALITY` was
+  forwarded — per-slot pins relied on apparent env inheritance which
+  was unreliable). Can be disabled via `AI_PIN_ROTATION=off` for
+  deterministic-pin testing. Commit `7105a14de`.
+
+  **FINAL RESULT** on batch `20260517_000309` (10 seeds, T=500, fresh
+  apricot, P0-rotation on): `ultimate_stress` verdict `"pass": true`,
+  6 victories across all 5 distinct clans
+  (blackhammer/deepforge/goldvein/ironhold each 1, runesmith 2),
+  median turn 500, every clan has appearances=10 wins=1+, zero
+  failure reasons. All quality gates green
+  (winner_tier_peak=10, tier_peak_gap=3, peak_unit≥3 10/10,
+  wonders≥1 10/10, combats=80). Gate closed.
