The zoom feature shipped without a task record while its index rows carried the
"TASK 51" label — which belongs to the webcam background effects (Remove + Blur).
For an honest catalogue and handoff:
- TASKS/task-52-zoom-box.md: feature provenance (creator-requested), the three
2026-10-08 corrections (loupe -> anchored capture over the full composite drawn
last -> never show the dim shading), shapes, implementation map, tests, DONE.
- TASKS.md: row 52 added (shipped); row 51 reworded — unblocked now that the
zoom build shipped.
- TASK 51 -> TASK 52 in Models/index.md, ViewModels/index.md, and the two code
comments that pointed at the zoom as "TASK 51".
- HANDOFF.md: pre-push readiness notes (5 commits ahead, push-safe).
Right-click now creates a transient ZoomSceneElement at z-index 1 whose pixels are a
genuine 2x magnified sample of the backdrop (live capture under art), composited into
stream/recording like any layer while the output crop stays the tier. All shapes are
centered on the click and clamped to frame; healed on load/scene-create, never persisted,
hidden from the layers list + element template (IsZoomLayer). BuildCompositorOptions is
now internal = always tier crop (test seam). ZoomFrameBuilder is a pure static sampler
(box/2 window centered on the box center, single-slot cache) proven by a banded-backdrop
test; LayerReorderPersistenceTests drag resolves rows by item since the collapsed zoom
row shifts container indices. Also books TASK 51 (webcam background Remove + Blur) and
syncs memory docs (HANDOFF, MyMistakes, indexes). Full suite: 405 passed, 0 warnings.
A webcam dragged between sources reverted to the bottom of the stack on
every relaunch: Source and WebcamSceneConfig each carried independent
per-type SortOrder counters, and Load appended all Sources before all
configs. Save now stamps both tables' SortOrder from the element's index
within scene.Elements; Load merges the two tables' rows by that shared z
(sources-first tie-break preserves legacy rows). Cross-type reorder now
survives a fresh LayoutStore reload.
Task 37 queued: defaults vs current layout split (creator directive) —
capture out-of-scope work in TASKS.md rather than folding it in.
Reorder: OnSceneElementsReordered now calls SaveLayoutNow() (was debounced
ScheduleSave) so a drag-drop persists instantly — one write stores the new
layer list (Source.SortOrder) and each layer's preview geometry (X/Y/W/H) in
the same rows. Reference: WPF ListBox drag-reorder requires an explicit persist
at drop; a debounce window lets a crash lose the drop.
Recording save dialog (RenameRecordingDialog.xaml): height 276→304 so the
Cancel/Save button row is no longer obscured; Save button named
SaveRecordingButton so the sizing test can assert it sits inside the client area.
Tests: deterministic seam test now asserts the dragged layer's geometry (preview
layout) is persisted with the new order; sizing test asserts 304 + textbox and
button-row bottoms within client area. 308/308 green.
Creator reported the layer reorder still "doesn't save" after the 08:18
fix (c117885). The existing Good Dog test short-circuited EndListDrag — it
called OnSceneElementsReordered() directly, so the actual
List_PreviewMouseLeftButtonDown/Move/Up handlers were never exercised
(synthetic RaiseEvent can't: e.GetPosition reads the physical cursor).
New RealMouseDrag_OnTheLayerList_PersistsTheReorder drives SetCursorPos +
mouse_event (Win32 input injection, the same technique UI-automation
tooling uses) so the REAL handlers run: click ImgC's row, drag it onto
ImgA's row on screen, release, then pump until the debounced save writes
the DB. Green: DB ends at [Background, ImgC, ImgA, ImgB] — the seam is
proven end-to-end. If the creator still sees a revert, the run binary was
stale (Debug exe 08:42 postdates the fix commit 08:18) or another deploy.
Reference: Win32 SendInput/mouse_event input injection for WPF e2e
(mouse_event docs / UI-automation tooling pattern).
List_PreviewMouseMove reorders StagedScene.Elements via RemoveAt/Insert,
bypassing SceneGraph's mutation surface, but never scheduled a save — the
new z-order was lost on restart. The drop now sets _dragReordered and
EndListDrag funnels it through MainViewModel.OnSceneElementsReordered()
(InvalidateBake + ScheduleSave, same background-save path as every other
mutation). Integration test (RealApp + temp DB) reproduces the exact
code-behind mutation and asserts the debounced save lands the new Source
SortOrder. Derivation reference: standard WPF ItemsControl drag-reorder
pattern (OBS layering semantics: bottom-most layer = index 0).
