# Design Panel QA Matrix
Campaign artifact for `docs/plans/2026-07-02-001-fix-studio-design-panel-inputs-plan.md`.
Environment: published CLI `hyperframes@0.7.26`, embedded mode (`npx hyperframes preview`
in a scaffolded `warm-grain` project outside the repo), Chrome via agent-browser.
## Step 0: demo-failure reproduction (baseline, pre-fix)
Reproduced. The demo symptom ("font size does nothing") is real, deterministic, and its
root cause is the **selection layer**, not the persist pipeline.
### S0.1 Master view: click on visible text selects the invisible top overlay
- Action: click the "Hyperframes" H1 (from `compositions/intro.html`, embedded in `index.html`).
- Selected instead: `.grain-texture` (`hf-0qtj`, label "Grain Texture"), the full-canvas grain
overlay on `data-track-index="100"`, even though its parent `#grain-overlay-comp` has
`pointer-events: none`.
- Panel then shows generic values (Size 16px) and a Text section with an empty Content field
for a div that contains no text.
- Committing Size 72px:
- signal a (disk): `index.html` changed, `<div style="font-size: 72px" ... class="grain-texture">`
- signal b (HTTP): `POST /file-mutations/patch-element/index.html` 200, `matched:true, changed:true`
- signal c (console/telemetry): nothing
- Visible effect: none (the styled element is an invisible overlay). This alone explains the
demo: every click lands on the overlay, every edit applies to it.
- Bucket: **selection/hit-testing** (new bucket; persist pipeline healthy in this leg).
### S0.2 Sub-composition view: hover finds the element, click cannot select it
- Setup: open `intro` in the sidebar (Master > intro breadcrumb), scrub to t=2s where the
title card is visible.
- Hover over the H1: teal highlight appears (hit-testing sees the element).
- Click (real mouse down/up at the text): no selection API call, no panel, no console error.
Reproduced with element-ref clicks and coordinate clicks.
- Bucket: **selection click-to-commit in sub-composition view**.
### S0.3 Stale selection target carried across composition switch
- After selecting `.grain-texture` in Master and switching the canvas to `compositions/intro.html`,
a subsequent click re-emitted the old target: `probe-element/compositions%2Fintro.html` with
`{hfId: hf-0qtj, selector: .grain-texture}` (an element that does not exist in intro.html),
followed by a selection PUT labeled "Grain Texture" with `sourceFile: compositions/intro.html`,
then `selection: null`.
- If a patch had been committed in that state it would have written to the wrong file or
silently no-oped (`matched:false`).
- Bucket: **selection state lifecycle across composition switches**.
### S0.4 Double-click on canvas element clears selection
- Double-click on the H1 in Master view: `PUT /selection {selection: null}`. No drill-down into
the sub-composition, no text editing mode. Users double-click text instinctively.
- Bucket: **selection UX** (candidate: intentional-but-hostile; confirm with maintainers).
### Working in this leg
- Persist pipeline end-to-end (patch-element → linkedom mutation → disk write → 200 with
`matched/changed`): healthy for the (wrong) selected element.
- Hover highlighting in both views.
- Panel rendering, section expansion, input commit on Enter.
### Instrumentation notes for the full matrix
- Fetch shim on `window.fetch` in the top document captures patch/probe/selection traffic
(studio app runs in the top document; composition renders in a shadow-DOM iframe).
- Element-ref clicks work for selection in Master view; sub-composition view needs
coordinate clicks (`mouse move/down/up`) and still fails to select (S0.2).
- Seek-slider `fill` does not move the playhead; use Play/pause or timeline clicks to scrub.
- GSAP warning noise in console: `GSAP target #a-roll not found` (from the warm-grain
captions comp; unrelated).
## Selection-layer fixes: embedded-mode re-verification (post-fix)
Environment: locally built CLI (commit with selection fixes), embedded mode, fixture copied
to a scratch dir outside the repo.
- Click on empty canvas over the invisible full-canvas overlay: selection resolves to
**null** (previously: selected the overlay). S0.1 fixed for real pointer input.
- Click on visible fixture text (`#qa-headline`): selects the H1 itself; panel shows real
values (Size 48px, weight 700, content "Static Headline") instead of overlay defaults.
- Font size commit 96px: `patch-element` 200 `matched:true, changed:true`; disk gains
`<h1 style="font-size: 96px" ...>`; preview renders 96px. The demo scenario works.
- Note for future automation: `agent-browser click @ref` on an element whose DOM box is
off-viewport can land on the sidebar "Select off-canvas element" helper buttons and
select programmatically, bypassing hit-testing. Use coordinate clicks on visible pixels
for selection tests.
## Full matrix (post selection + U3 fixes, embedded mode, locally built CLI)
Instrument: scripted agent-browser runner (`matrix-runner.mjs`, session scratchpad) + interactive
follow-ups. Signals per cell: patch/gsap-mutation HTTP response, disk content, computed style,
reload survival.
### Selection (click on canvas, Inspector enabled)
| Archetype | Result |
| ----------------------- | ------------------------------------------------------------------------------------------------- |
| Static text (h1) | selects the element itself |
| Multi-span child (span) | selects the span itself |
| GSAP-tweened box | selects the element |
| Keyframed box | selects the element |
| Image | selects the element (canEditStyles true) |
| Shape div | selects the element |
| Video | selects the element (visible only inside its clip window; hidden outside, correctly unselectable) |
| Runtime caption word | falls back to the parent host (runtime nodes cannot persist; by design) |
| Sub-composition child | selects the child with sourceFile pointing at the sub-composition file |
### Inputs (all persist to disk with matched:true/changed:true and survive reload)
- Text on h1: size, content, weight, line-height, letter-spacing, align, case, style. Span-self
size also works.
- Layout on shape: W, H, rotation persist as `tl.set(...)` in the GSAP script (designed manual-edit
path); z-index persists inline.
- 3D: rotationX persists via the `gsap-mutations` endpoint (ok:true, changed:true).
- GSAP-tweened element: Layout X persists as `gsap.set("#qa-tween-box", { x: 40 })` appended to the
script. Works; note: a load-time `gsap.set` on an element that also has an x tween is semantically
debatable (starting value shifts) — flag for maintainers, not a broken input.
- Timing: start persists as `data-start="0.20"` (normalized to 2 decimals).
- Video section (titled "Video", not "Media"): volume slider persists `data-volume="0.8"`;
object-fit select persists `object-fit: cover`.
- Transparency: opacity range persists `opacity: 0.8`; blend select persists
`mix-blend-mode: multiply`.
- Radius text input persists `border-radius: 24px`; Effects blur range persists `blur(4px)`;
Clip overflow select persists `overflow: hidden`.
- Sub-composition child: Text size persists to `compositions/qa-sub.html` (`font-size: 48px`).
### Confirmed bugs
- **U4 child text-field escaping** (persist-level, confirmed by the headless harness test
"documents U4 bug: child text-field style persists as escaped markup"): editing a child field of
a multi-field element serializes markup into a `text-content` op that the server escapes.
### Notes and paper cuts (not input bugs)
- Inspector defaults OFF on a fresh embedded-mode load; canvas clicks silently do nothing until it
is toggled on. Zero feedback for the user in that state.
- Fill color picker: opens with a hex input reflecting the current color; persist path verified
green by the headless harness (fill style op); scripted popup commit was flaky (focus-sensitive
popup), verified manually instead.
- Color grading section absent for img/video: expected (flag `VITE_STUDIO_ENABLE_COLOR_GRADING`
defaults off).
- Automation notes: media/timing cells must run with the playhead inside the clip window (a
data-start edit hides the element at t=0, which is correct but confuses naive re-runs); commit
fires on Enter/blur only when the draft differs from the last value.
