Calcenon → Route 4 stationary trainer exclusion review

Source-only independent review of calcenon_agate_queue.py's --allow-source-avoided-trainers, 2026-10-03. No game input, fresh capture, active native/save, or recording access was used. The running queue was not modified.

The exception is suitable for the installed climb prefix 412 → 710 → 711 → 713 → 714 → 715. It is restricted to the five climb maps and accepts only stationary player-touch events with an exact Trainer(n) name and a valid source facing. Moving, autorun, unnamed, and other automatic battles in the scanned trigger set still stop the queue. It inserts the NPC tile and all n source sightline tiles into the planner's hard avoid set before eventq plans any walking.

nav.route merges these tiles into blocked. Ordinary movement rejects them; native ledges reject both their intermediate tile and their landing; scripted/forced jumps reject their landing. layer_route.plan uses the same route graphs for both layer states, and its cache key includes the planner state, including the exclusions. layer_walk therefore retains the hard exclusions.

Installed stationary trainers on the remainder of this prefix:

Installed source arrivals and climb staging positions are outside these sightlines. Map 713's forced jumps occupy x24–43, away from its trainer at x54. A static scan of the prefix's event pages found no controller moving or turning these trainers and no parallel-process battle. Map 412's conditional unnamed wild encounter remains rejected by this exception when its page is active.

Two generic boundaries should remain explicit: the guard scans trigger 1/2/3, not parallel trigger 4, and a scripted jump's intermediate transit tiles are not checked individually. Neither creates a concrete overlap in the installed prefix reviewed here. Reusing this exception for different maps or changed event pages needs a new source review. No helper fix was needed for the current route.
