* feat(core): data-vfx-chain defs and chain parsing (mirrors data-fx-chain)
Mirrors audioFx.ts's shape for the per-pixel VFX chain: a versioned
JSON chain attribute (data-vfx-chain), a def registry with typed
params (number/enum/bool/ref), and parse/serialize/normalize helpers.
HF_VFX holds one def, fractal-noise, with a placeholder frag; the
kernel and its consumers (packages/core/src/runtime/vfx.ts) land in
Task 1.2/1.3 of the vfx-chain-runtime plan, so vfx.ts is added to
.fallowrc.jsonc's entry list for now.

* test(vfx): chain order is nesting order; preceding CSS effects are captured
...and following ones apply outside. The plan's one-line message for Task 2.4
is 105 characters; commitlint caps the header at 100, so the tail moved here.

* feat(telemetry): vfx node count, capture class and types on render_complete
Threads vfxNodeCount, vfxCapture and vfxTypes from a static scan of the
compiled composition's data-vfx-chain hosts (mirrors the existing
compositionElementCount/colorGradingCount scan) through
RenderPerfSummary.drawElement into the render_complete event, next to
de_capture_mode. Exports chainCapture/parseVfxChain/HfVfxCapture from
@hyperframes/core's index for the producer to consume. The PostHog
dashboard tile is not created here — left for the coordinator.

* docs(vfx): data-vfx-chain guide — element shape, capture table, Studio flag, known constraints
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
* fix(vfx): register chain hosts that arrive with a sub-composition mount
`initVfx(document.body, fps)` ran once, synchronously, three lines after
`void loadExternalCompositions(...)` — so every `data-vfx-chain` host that
enters the DOM only when a `data-composition-src` mount resolves was never
registered. An unregistered host paints nothing and reports nothing: no
`[HyperFrames] composition script error`, the `.hf-vfx-out` canvas keeps its
300x150 default, and `paintVfx` never even arms the page-composite flag.
Measured on a real multi-file export served raw: `#main-l5-text`'s output
canvas stayed 300x150 and `window.__timelines` never gained the sub-comp.
Re-scan in the loader's `.finally`, before `maybePublishRenderReady()`, so
registration precedes readiness. `initVfx` now releases the outgoing
registry's programs, capture textures and ping-pong targets first — the
output canvas hands back the same WebGL2 context on a re-scan, so the
previous pass's GL objects would otherwise leak.
Two browser cases in `vfxDeterminism.test.ts`, both against the real runtime
bundle: a host whose `.hf-vfx-in` IS the mount (already worked — the mount
replaces the wrapper's children, not the wrapper, so the registered source
node survives), and a host that arrives INSIDE a mounted sub-composition
(failed with `armed: false` and no error; passes now).

* fix(vfx): runtime tsconfig typecheck passes
Under noUncheckedIndexedAccess, resolveCaptureSource's null return
widened VfxEntry.src past its VfxCaptureSource | undefined type; the
function is internal-only, so its return type moves to
VfxCaptureSource | undefined instead. Indexing PingPong.framebuffers
by a non-literal index produced | undefined against
WebGLFramebuffer | null, coalesced to null. No behavior change.

* fix(vfx): structural DOM predicates instead of realm-bound instanceof
vfx.ts checked `instanceof HTMLCanvasElement`/`HTMLElement` directly, which
returns false for inner-realm nodes when the Studio previews across an
iframe realm. domRealm.ts had no canvas predicate yet, so this adds
isCanvasElement mirroring the existing isImageElement pattern, then swaps
all three vfx.ts checks to the structural predicates the lint guard requires.

* fix(vfx): paint self-capture hosts under hyperframes snapshot, not only the engine path
`paintVfx(t, { engineMode: true })` armed the page-composite protocol and
returned, betting that every capturing chain runs under `frameCapture.ts`.
`hyperframes snapshot` (and check/compare/validate/layout, and Studio's
thumbnail capture) seek through the same `renderSeek`, never read
`__hf_page_composite_pending` and never call `__hf_page_composite_resolve` —
so a `self` chain painted nothing there, in silence, because its content
lives in a `layoutsubtree` canvas the browser never paints directly.
Engine mode now arms the preview-side capture as well and paints on whichever
completes first. A seek token stops a superseded async capture from repainting
a newer frame, and a registry-identity check stops it painting an entry
`initVfx` already released. `resolveVfxCapture` stays non-idempotent on
purpose: the engine resolves only after its own before-capture hooks have
mutated the DOM, so its capture is still the authoritative one.

* fix(vfx): an exporter-emitted .hf-vfx-out gets the box the spec fixes for it
findOrCreateOut adopted a canvas the exporter had already emitted without
applying the layout cssText, so it kept the default position:static;
display:inline and wrapped to the line AFTER the layer-wide .hf-vfx-src
canvas — painting a second, misplaced copy of the layer one full layer
height below the host. Measured on retro-wave #main-l6-text: .hf-vfx-src
rect top 315.1 h 93.0, .hf-vfx-out rect top 409.2, both style=null,
position static (ae-mcp findings Task 3.5b). Hosts with no emitted
out-canvas were never affected, which is why only this one host moved.

* refactor(telemetry): vfx_node_count counts hosts, not chain nodes — rename to vfx_host_count
The field increments once per `data-vfx-chain` attribute occurrence, never
per node inside a chain's JSON, so the name promised something the scan does
not measure. Renames the internal `vfxNodeCount` and the wire property
`vfx_node_count` to `vfxHostCount`/`vfx_host_count` across the orchestrator
scan, the perf summary, the CLI render path and the telemetry event. No
dashboard consumes the field yet, so the wire rename costs nothing now and
would cost a migration later.

* fix(vfx): join the preview capture to the seek-completion barrier, not race it
`paintVfx` fired `capturePreviewThenPaint` and forgot it, so nothing the CLI
awaits waited for a `self` chain's paint. Every snapshot-family command
(`snapshot`, `check`, `compare`, `validate`, `layout`) seeks through
`seekCompositionTimeline`, which drains `window.__hfWaitForSeekCompletion`
and then allows one settle race before screenshotting — and only the
`"hf-seek"` event's `waitUntil()` could put anything in that barrier. The
screenshot therefore landed on however many hosts happened to have finished,
which varied with host count and machine speed.
Extracts the "track, untrack on settle, retain the first rejection" block
`dispatch()` built inline into an exported `registerSeekCompletion`, and has
`paintVfx` register the preview capture through it. Also awaits the per-host
paints with `Promise.all` instead of sequentially: N hosts cost about two
animation frames now, not 2N.
Measured on the pre-fix bundle with two `self` hosts, both output canvases
read `[0,0,0,0]` at the moment the barrier returned; they painted only
because the settle race that follows happened to be long enough. Both tests
added here fail on that bundle.

* fix(vfx): report WebGL context loss loudly instead of silently no-op painting
One WebGL2 context per `data-vfx-chain` host, against a browser cap that is
commonly 16 and shared with `colorGrading.ts`'s per-element contexts. A lost
context makes every later call on it do nothing, per spec — so the chain kept
"painting" a blank canvas with no error, which is exactly what the module's
loud-failure contract exists to prevent.
Adds the `webglcontextlost` listener pair's first half, following
`colorGrading.ts`'s precedent: `preventDefault()`, mark the entry, report
once through `reportVfxError`. The entry is then skipped by `paintVfx`,
`capturePreviewThenPaint` and `resolveVfxCapture` — silently, since the one
loud report already happened and repeating it per frame is spam.
Restore is left unhandled on purpose, with the reasoning in the doc comment:
`initVfx`'s existing re-scan already rebuilds every GL object, and a second
narrower rebuild path for `webglcontextrestored` would duplicate it. The
shared-context redesign the review floated is likewise out of scope here.

* perf(vfx): cache uniform locations at pass-build time instead of querying every paint
`setPassUniforms` asked the driver for `u_size`, `u_t`, `u_fps` and every
param's location on every paint of every pass, and `bindPass` did the same
for `u_src` on every bind. `buildPasses` already constructs each `VfxPass`
once at init, right after the program links, and a linked program's
locations never change — so they are resolved there now and read from
`pass.locations` in the hot path.
Same values, same `null`-means-optimised-out semantics (`gl.uniform*(null,
…)` is a defined no-op, which is what the per-frame query produced too), so
the existing vfx.test.ts and the browser determinism suite cover it
unchanged — both still green, the latter against a rebuilt runtime bundle.

* fix(vfx): bound the paint wait per host so a stalled compositor can't hang the seek barrier
`paintVfx` registers `capturePreviewThenPaint` into the shared seek-completion
barrier (48aaa2bbb), and that promise settled only via `awaitCanvasPaint` — a
race between the canvas `paint` event and a double-rAF chain. Under BeginFrame
control (Linux headless-shell, `drawelement` capture) neither can fire before
the barrier is drained: `frameCapture.ts` awaits the barrier in
`prepareFrameForCapture` (~2692), while the frame's
`HeadlessExperimental.beginFrame` is issued later, in the per-frame capture
stage (~3797). Fire-and-forget that was harmless; registered it can stall every
`__hfWaitForSeekCompletion` caller, the engine's render path included.
rAF-under-BeginFrame: CONFIRMED gated, from this repo's own engine notes —
`frameCapture.ts` ~2445 ("waitForFunction uses rAF polling internally, which
won't fire in beginFrame mode") and ~4755 ("headless only fires rAF when a
frame is produced, and nothing produces one until a screenshot asks"). Not
reproduced locally: every environment here is macOS with a free-running
compositor (`beginFrameTimeTicks === 0`). `setTimeout` is not compositor-gated
there — `drawElementService.ts` ~341 describes its 250 ms paint fallback as
burning on every BeginFrame frame, which requires the timer to fire — so a
timer ceiling is a sound escape.
`awaitCanvasPaint` now resolves `"painted" | "timeout"` with a 2000 ms ceiling
(the repo's own `BEGINFRAME_PROBE_TIMEOUT_MS`; ~20x a real two-frame paint,
far short of the ~180 s CDP `protocolTimeout` a hang would burn). The race is
per host, so one stalled compositor no longer delays hosts that would have
painted; a timed-out host is skipped (no capture, no guessed pixels) and
reported loudly. The report is not suppressed in engine mode: `frameCapture.ts`
~2708 skips `__hf_page_composite_resolve` in `drawelement`/`beginframe` modes,
so there is no authoritative second attempt to defer to there.

* chore(ci): re-pin test-classification.mjs hash after registering vfxDeterminism.test.ts
An earlier commit added vfxDeterminism.test.ts to INTEGRATION_TEST_FILES;
check-test-reachability.mjs pins a sha256 of that file to force a conscious
review whenever it changes. Reviewed: runner[1]'s glob already covers the
file structurally, the classification move (unit -> integration) is correct
for a Chrome-launching test, and the pinned hash is now current.

* chore(core): regenerate position-edits-render-inline.ts for Linux esbuild output
check:position-edits-render (bun run build:position-edits-render && git diff
--exit-code) failed on both Linux CI runners (Test (runtime), Tests on
windows-latest: studio-core) but passed on macOS: esbuild's minifier named
two identically-scoped WeakMap/function bindings differently on Linux than
on the mac that last committed this artifact, and the divergence appeared
only on this branch (main's own current tip passes CI cleanly), so it is
tied to a change on this branch rather than a random flake, even though it
is not attributable to any specific line of that change.
Confirmed stable across two independent Linux CI runs (byte-identical diff
both times) and reconstructed directly from that diff rather than guessed:
the committed content, byte length (3817), and 3/3 existing artifact tests
all match. A future contributor rebuilding on macOS will see this same
diff again in the other direction until the build script's cross-platform
determinism is fixed at the esbuild-invocation level, which is out of this
PR's scope.
