Three reports from the creator, plus two bugs the real clip exposed.
1. A video layer was INVISIBLE in the preview. The pane's per-layer Image is Collapsed by
default and switched on by a whitelist of DataTriggers; MediaSource matched none, so the clip
decoded into a bitmap that nothing displayed. Same defect the alert box hit on 2026-09-26 and
the scoreboard after it — now recorded at the top of docs/ai/ui-surface.md with a test that
asserts the bound Image is Visible (`MediaPreviewDisplayTests`).
2. Play is no longer tied to Loop: the button is always enabled (creator ruling — Loop must not
toggle Play). Loop still restarts a finished clip, which is the behaviour that was broken.
3. Geometry is now the LAST section of the properties list for every draggable element, with
opacity at the top; the web source's duplicate geometry block is gone (it now uses the shared
one, which had been sitting above the media panel).
4. The physical mouse-drag test is deleted. It injected real cursor movement, hijacked whatever
machine ran it, and failed whenever the desktop was busy. The arithmetic it covered now lives
in `Helpers/DragReorderMath.cs` — pure, and covered by `DragReorderMathTests` (threshold,
up/down moves, no-op and out-of-range). The two persistence tests were already synthetic.
5. Real-clip check (creator's `test_greenscreen_moving_subject.mp4`, 1920×1080): the detector
REJECTED it — a fully saturated green sits at value 1.0 and the detector's 0.98 brightness
ceiling threw it away. White highlights are excluded by the saturation floor, which is the
property that actually separates them, so the ceiling is gone. With it fixed, the clip is
detected as green (high confidence), and keyed through our own pipe 97.8% of pixels go
transparent. Measured: keying with the canonical #00B140 keys 0.0% of this clip — which is why
the key colour comes from the measured screen.
Tests: 567 passed, 0 failed, clean build 0 warnings. The gate's scope check flags
`Assets/Videos/test_greenscreen_moving_subject.mp4` — the creator's working copy, deliberately not
committed; the fixture lives under ytLive.Tests/Fixtures.
Reported 2026-11-05: "when I click Loop, the video doesn't play in the preview pane". Two
causes, both real:
- `VideoClipPipe.StartAsync` bailed out once it had run once (`_run != null`), so a clip that
reached EOF could never be started again — it held its last frame forever.
- Loop is only consulted at end-of-file by a LIVE decoder, so flipping it on a finished clip
did nothing at all.
Now: the pipe reports running state and is restartable after a natural end; the manager marks a
session finished (keeping its last frame) and exposes `IsRunning`/`RestartAsync`; the layer shows
`IsMediaRunning`/`IsMediaFinished`; flipping Loop on a finished clip restarts it.
UI: `▶ Play` sits to the right of the **Video File** label and is enabled only while Loop is off
(creator ruling: with Loop on the clip already runs continuously, so there is nothing to start).
The panel says "Clip finished — holding the last frame." so a frozen picture explains itself.
Also: verify.sh no longer runs physical-input tests by default. That test moves the real cursor
(SetCursorPos + mouse_event); running it mid-gate hijacks the machine someone is using, which is
exactly how it felt. Opt in with PHYSICAL_TESTS=1 when the desktop is idle; the header documents
the scoped-run command for working hours.
Test: `MediaPlaybackRestartTests` (pipe restart, finished state, Play again, Loop-on-finished).
8 scoped tests green. FULL SUITE NOT RUN — the machine was in use; run scripts/verify.sh in a
quiet window before the next milestone.
TASKS.md 467 → 66 lines: one line per live item, detail stays in TASKS/
task-*.md. The old catalogue (63 rows of paragraph status prose plus the
historical narration) is preserved verbatim as TASKS/archive.md — a
2026-10-29 snapshot, not the live queue. The "out of product" list and every
retired decision moved to docs/ai/decisions.md with cause of death.
HANDOFF.md 440 → 40 lines, and it is now OVERWRITTEN, not appended: branch,
what's in flight, next action, live landmines, pending creator checks. History
belongs to git log; the previous handoff is reachable at ee3c592:HANDOFF.md.
docs/ai/decisions.md (new) collects what no longer governs: the paid tier and
its pricing, Polar, Store IAP, the Store route and why it died, the deleted
Velopack updater, signing economics, the retired monetization ideas, and the
permanent out-of-product list.
Facts that lived in the old ai.md "Current limitations" section were re-homed
rather than dropped with the router rewrite: OAuth/DPAPI/session behaviour →
docs/ai/youtube-api.md; paths, persistence and the Google project number →
docs/ai/environment.md.
verify.sh caps now cover all four always-read files (AGENTS 210, ai 100,
HANDOFF 40, TASKS 120).
Docs-only unit: scope-check run, no build.
ai.md 228 → 64 lines. It now carries only: what the product is, the build
commands, the architecture table, a "where the truth lives" table, and a
pointer to HANDOFF. No narrative, no status, no duplicated invariants.
AGENTS.md (195 lines) is now the single always-read file:
- the 20 invariants that break output, wipe user data, or ship a legal/trust
breach — one line each, pointing at the doc that explains it (they replace
110 lines of invariant stubs that duplicated docs/ai/*.md verbatim)
- Response style + No-Fluff Mode moved in from ai.md (rules belong in the rules file)
- onboarding is now: HANDOFF → ai.md router → the ONE docs/ai file → dir index;
TASKS.md is read when the question is "what's next", not to write code
- memory rides with the change but is no longer a unit of its own; HANDOFF is
≤40 lines and overwritten, never appended
Anti-rebloat gate: scripts/verify.sh gains step 1/4, a doc-budget check
(AGENTS ≤210, ai ≤100; HANDOFF/TASKS caps land with the queue trim). A commit
that pads a capped file instead of moving detail fails the gate.
schema.md and docs/index.md corrected for the new roles and reading order.
