Fold Daniel's decisions into CONTEXT.md, PLAN.md, and the product notes:
- Fork 1 (persistence): pool folds into the `banks` blob; legacy
`bank_index` key retired after a one-way lossless migration.
- Fork 2 (delete): delete drops member index entries; add an `evacuate`
verb (B1 pure op + B3 action) returning members to the pool. Design the
orphaned-until-prune window and confirm-on-non-empty-delete guardrail.
- Fork 3 (move): move is the default gesture, copy the deliberate secondary.
- Fork 4 (active bank): active-bank and shown-tab stay distinct; the
active-bank indicator must be visually unmistakable.
Fork 5 (tab rendering + move affordance) remains open with an options
analysis and pending recommendations. Additive; M0-M11 and Phase D untouched.
