A bank-panel capture dropped onto a track with pre-existing content was
auto-tagged into the active mode, forcing a multi-mode lane split whose
toggle silenced the pre-existing items. New items now adopt the single
mode of their track's prior content; deliberate splits stay on the
explicit item-move path.
An item inserted onto an already-split folder in Design mode sat on the
correct lane but stayed invisible until a manual toggle: mintManagedLanes
returned on the idempotent no-op path before its UpdateArrange call. Force
the redraw there so the item appears immediately.
Add three MIDI-bindable item actions mirroring the track tag family, routed
through the shared hookcommand: retag selected items' membership then re-drive
mint/apply so each lands on its mode's managed lane (manual-lane items exempt),
all in one undo block. Extract shared item_read seam, simplify applyMintPlan's
lane-count pass, and guard reconcile against unregistered-mode lanes.
Drive C_LANESCOLLAPSED=2 and hide lane buttons only on tracks the tool itself splits
(gated on the pre-write I_FREEMODE read, so user comp-lane display prefs are never
stomped). Lazy-mint managed lanes only for modes with own content, never an empty
reserved lane; confinement holds via C_LANEPLAYS on the lone lane.
planLaneMinting now takes the model + folder tree and splits a track visible in
2+ modes that carries own media (own-item span OR folder derived-visibility),
fixing an item dropped on a cross-mode folder leaking into every mode. Show-both
tracks are never force-split.
Pure planLaneMinting decides which tracks hold >1 mode's content and which managed
lane each item lands on; view.cpp applies it (I_FREEMODE/I_NUMFIXEDLANES/P_LANENAME/
I_FIXEDLANE) under one undo block, driven off the auto-tag detection tick. Manual lanes
and their items are never touched. Load-time reconcile rebuilds ownership from durable
lane names before reapplying active-mode visibility.
Drives fixed-lane C_LANEPLAYS for managed lanes only (name-keyed, ordinal-renumber
safe) in the view shell; diffs live track/item GUIDs on the panel timer to auto-tag
new content to the active mode, first-poll-guarded. Pure guid_diff + lane_keys
modules unit-tested; folds in Wave-1 polish.
Extends the REAPER-free view_mode_model for per-item mode membership via fixed
lanes: lane->mode C_LANEPLAYS mapping, managed-vs-manual lane-ownership index,
managed-only item-lane ops in the toggle planner, "which lanes may this toggle
touch" query, auto-tag decision (manual-lane items exempt), and JSON round-trip
of the lane index. D1 behavior and tests unchanged.
Add ViewModeModel::reconcile(liveGuids) to prune snapshots of deleted
tracks; wire it into applyMode before planning. Keep membership so
undo-delete (same GUID) preserves the Design tag.
visibleTracks pass 1 now evaluates every node (parent or leaf) by its own
membership, so an untagged folder carrying its own FX/media shows in Arrange
(its default) as well as any mode derived from its children. Adds case-matrix
tests; updates the nested-Arrange assertion to the corrected rule.
Only capture a track's pre-park snapshot when none exists, so a re-park while
already parked no longer overwrites it with hidden-state zeros (leaves vanished
after toggling twice). Undo label now names the actual target mode.
planToggle now enumerates all leaves in the FolderTree instead of only tagged
membership entries, so untagged (Arrange-member) tracks park in Design and
restore in Arrange. applyMode calls TrackList_AdjustWindows + UpdateArrange so
changes render immediately. Correct the stale "tagged-only" invariant comments.
Register toggle/activate/tag/untag/show-both actions driving the D2
shell and D3 model; reapply saved active mode on project load via a
persist load-signal seam. Shared guidString helper; pure nextModeId
unit-tested.
