main vs migration · day 15

Apr 2026

Main's near-miss was at an established site being tended; alt2-migration's was at the forward edge of its range during an active push. Main recovered food from the same spot that nearly dropped it. Alt2-migration took a real health cost but the fall paid something back: the colony ground is now in view.

main

YY returned to the east channel to tend it; bark shelf gave underfoot; caught a fork; foraged from that position; food up slightly, health minor dip, attention high; east path now has a gap where the shelf was.

migration

YY pushed northeast along the stream toward the rise; bank gave at the curve; scrambled back; cold water, real health cost; from the recovery position the colony ground is visible past the rise for the first time — closer than any deliberate approach had reached.

key differences

—risk profile: main tending established territory, alt2-migration advancing at its physical limit
—health cost: main minor dip (0.77→0.74), alt2-migration significant drop (0.54→0.48)
—what the hazard gave back: main kept its channel, alt2-migration gained a sightline to the colony
—food: main up slightly, alt2-migration unchanged
—attention: both up, but for different reasons — main from survival reflex, alt2-migration from new directional information
—forward momentum: main consolidating, alt2-migration now has visual confirmation of the goal
