Cut the null-test verify action and pre-FX-dry mechanism (Daniel's
call); keep provenance + re-capture-from-source. Sample.provenance
already exists/round-trips (M1), so M10 populates and consumes it. Add
docs/product/provenance.md with dual-canvas forks P1-P4 and the leaned
bank-only path; rewrite PLAN.md M10 as a proposal pending fork picks.
Replace the ...-with-tail variant actions with a pure tail_control module +
a docked-panel footer toggle (Off/Auto/Manual) read by CAPTURE_ITEM/TRACK.
Default None (byte-identical); Manual fixed 2s, in-memory session lifetime.
Tail mechanism unchanged; retired the variant ids.
Update the CLAUDE.md FX-scope invariant to item+track only; note master
removal in COMPLETED.md; drop master references from the tail spec and PLAN
Milestone T; realtime now taps the selected track.
Item-level mode separation via REAPER fixed lanes; new content auto-tags to
the active mode; inactive lanes hidden and silenced; a managed-vs-manual lane
index keeps toggles off user comp lanes; capture placement mode-aware.
Precision invariants unaffected; REAPER 7 floor.
5a: named-banks tab strip is LICE-drawn (matching M5 grid + Design View
segmented switch), with overflow/scroll in scope from B4 start.
5b: move ships as both a bindable "move to bank" menu and drag-between-regions;
copy stays the deliberate secondary act. Drag mis-drop mitigated by drop-target
highlighting and recoverable by design (index-only, reversible).
Phase B now fully settled (all five forks resolved), ready to scope into
implementation waves; only the active-bank indicator placement polish remains.
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.
Add the multi-bank pillar as Phase B (lettered, parallel to M-line and
Phase D): CONTEXT.md §Multi-bank spec, PLAN.md Phase B block (B1 bank_book
pure / B2 persist / B3 actions / B4 panel split), and docs/product/multi-bank.md
framing. Additive only — BankIndex, the M0–M11 roadmap, and Phase D untouched.
