feat(errand): handover memory carries courier position + behaviour flags on the text path

feat(errand): director grass-aware persona routing — civic avoids lawn, cut personas take the grass shortcut

refactor(errand): share policy radii via errand_world, symmetric wallet radius, errand-specific memory legend

refactor(errand): C1 review — reuse w.footprint, precompute wallet field, fix ped drift, type hints

feat(errand): single-agent BFS-routed memory + 3 persona variants on MEMORY_LAYOUT

merge: errand_runner scenario (visual-only city errand + find-your-body discovery)

feat(memory): author_errand_runner persona demo (cells overlay + npc pedestrian) + default_memory

polish(director): restore natural 'all seated' terminal event; robust event test

fix(director): emit each seating event once; guard truncated 'all seated'; tidy

feat(director): author_take_a_seat memory (norms grab nearest seat, a0 circles to far seat)

feat(director): predator_chase pack scatters (all survivors flee) after the first kill

feat(director): predator_chase memory — longer pre-kill preroll + wider, varied agent roaming

fix(director): agents never overlap in authored memory (agent-agent collision avoidance)

refactor(scenario): rename pack_flee -> predator_chase

fix(resource_race): collected resource leaves the field (live sprite removal + memory pickup frame)

feat(director): author_resource_race multi-agent winner memory

feat(director): author_pack_flee multi-agent survivor memory
