fix(runtime): auto-infer composition duration for CSS/WAAPI/Lottie so data-duration is optional (#1830)
* fix(runtime): auto-infer composition duration for CSS/WAAPI/Lottie so data-duration is optional The #2 render failure bucket ("Composition has zero duration") accounts for ~27K errors / ~7K affected users over 30 days (PostHog project 356858). Root cause: only GSAP timelines got their duration auto-detected — CSS, WAAPI, and Lottie compositions had no source of truth for total duration unless the author remembered to set data-duration on the root element, and the render engine hard-failed capture when neither was present. Adds getInferredDurationSeconds() to the CSS, WAAPI, and Lottie runtime adapters (packages/core/src/runtime/adapters/*.ts) — each reports the longest finite end time it can discover from its own animations (CSS: computed timing offset by data-start; WAAPI: effect.getComputedTiming().endTime; Lottie: totalFrames/frameRate or the player's own duration). Infinite/ unbounded animations correctly return null and still require data-duration. Wires this into the runtime's existing duration-floor resolution (resolveAdapterDurationFloorSeconds in runtime/init.ts), alongside the existing media-duration and authored-composition floors, so window.__hf.duration becomes positive without any author action for finite-duration non-GSAP compositions. Three.js is unchanged — no AnimationClip/AnimationMixer inspection exists in that adapter, so data-duration remains required there. Tightens frameCapture.ts's zero-duration fast-fail gate to also check hf.duration directly (not just the two authored signals), so a composition mid-inference isn't fast-failed before its adapter-derived duration lands. Adds a new lint rule (root_composition_missing_duration_source) that errors only on genuinely non-inferable cases: no animation signal at all, Three.js without data-duration, or an infinite/unbounded CSS or WAAPI animation without data-duration. Deliberately silent on finite CSS/WAAPI/Lottie animations, since the runtime now infers those — an autofix that "inserts the inferred value" was considered and rejected: every case the rule flags has no derivable value (an infinite spinner has no finite end time; a duration-less Three.js scene has nothing to measure), so any autofix would have to fabricate a placeholder, trading a loud correct failure for a silent wrong-length render. Updates the CSS/WAAPI/Lottie/Three adapter skill docs and the hyperframes-core determinism-rules/data-attributes references to document the new optionality and the runtime mechanism backing it. Verified end-to-end against the real render pipeline (not just unit tests): a CSS-only composition with a finite 3s animation, no GSAP timeline, and no data-duration now renders a correct 3.000s MP4 via `hyperframes render` (previously: "Composition has zero duration" failure). The infinite-CSS negative control still fails fast with a clear diagnostic, matching the new lint rule. Adds a file-level fallow health exemption for lottie.ts's pre-existing `seek` handler — unrelated to this change, but its line numbers shifted when new functions were added earlier in the file, tripping fallow's inherited-finding fingerprint (documented pattern already used elsewhere in .fallowrc.jsonc for the same reason). Known limitation: the static WAAPI usage detector in the lint rule (/\.animate\(\s*[\[$A-Za-z_]/) can miss unusual call shapes; it only affects whether the "no signal at all" branch fires, and errs toward NOT flagging (reducing false positives) rather than over-flagging. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(lint): close 3 correctness gaps in root_composition_missing_duration_source - Strip JS/CSS comments before scanning for GSAP/WAAPI/Three/Lottie/CSS animation signals, so a commented-out `.animate()` call or a commented `animation: ... infinite` rule can no longer satisfy the "has a duration source" check and mask a real zero-duration render failure. - Broaden the WAAPI detection regex to also match the object-literal (PropertyIndexedKeyframes) form of `.animate()`, e.g. `el.animate({ opacity: [0,1] }, { duration: 2000 })`, which the previous character class silently missed. Corrected the adjacent comment that incorrectly claimed this shape "can't be a false negative". - Fix hasInfiniteCssAnimation to stop false-positiving on animation NAMEs that merely contain the substring "infinite" (e.g. `infinite-spin`) by anchoring the `infinite` keyword with hyphen-aware boundaries instead of a bare `\b`. Also makes the longhand `animation-name` + separately declared `animation-iteration-count: infinite` pattern detected consistently. Adds targeted unit tests for each fixed false-positive/false-negative. * fix(runtime): keep finite duration signal when an unbounded animation coexists getInferredDurationSeconds in the CSS and WAAPI adapters returned null outright whenever any animation on the composition was unbounded (infinite iteration count), even when other finite animations on the same composition could still supply a valid duration. This disagreed with the new root_composition_missing_duration_source lint rule, which treats any animation-name as sufficient — so a composition mixing a finite fadeIn with a decorative infinite spin passed lint but still failed at render with "zero duration". Unbounded animations are now skipped when computing the max end time instead of short-circuiting the whole calculation. null is only returned when every animation on the composition is unbounded, i.e. there is no finite signal to fall back on at all. Co-Authored-By: Claude <noreply@anthropic.com> * docs(skills): fix table separator width in data-attributes.md oxfmt flagged the merged Composition Root table from the post-rebase merge of the auto-infer-duration docs onto main's reformatted table — the separator row was one dash short of the header width. * fix(lint): keep infinite-CSS duration rule strict but make its message honest Post-review (Vance): after the finite+infinite adapter fix, the runtime infers a length for a mixed finite+infinite CSS composition, but this lint rule still (intentionally) errors on it — an unbounded animation makes the intended total length ambiguous, so we require explicit data-duration. Keep that strictness (lint is advisory by default; it only blocks under --strict, and data-duration is the one duration signal guaranteed correct across every adapter, known and future). But the message wrongly claimed the render "will fail" — false for the mixed case, where the runtime falls back to the finite animation. Rewrite it to describe the ambiguity honestly, correct the rule's block comment, and add a mixed finite+infinite test asserting it still errors with an honest message. --------- Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> |

feat(runtime): swallow() helper replaces empty catches in inlined runtime
After hf#641 inlined the runtime IIFE into every bundle, lint tools
inspecting bundled output (including Abhay's c2v eval) started flagging
empty `catch {}` blocks across the runtime. The source had explanatory
comments inside, but esbuild's minifier strips them — the IIFE ships
~10 visible patterns of `}catch{}` and consumers' linters fire on each.
Each empty catch is intentional best-effort error swallowing —
postMessage to a parent frame that may not exist, `media.play()` /
`pause()` that throw under autoplay restrictions, timeline `seek()` on
a disposed timeline, anime.js / lottie feature detection on hosts that
don't load those libraries, etc. The right behaviour stays "tried,
didn't work, move on", but doing it visibly improves three things:
- lint clean: helper call is a real statement; no `no-empty` warnings
survive minification
- debuggable: flip `window.__hfDebug = true` in DevTools to see every
swallow site with `console.debug` (silent in prod by default)
- observable: studio / embeddings can install
`window.__hf.onSwallowed = handler` to collect runtime swallow
events without polluting the page console
Implementation: `packages/core/src/runtime/diagnostics.ts` exports
`swallow(label, err?)`. 41 catch sites across 12 runtime files
converted via mechanical pass (auto-generated `runtime.<module>.siteN`
labels — labels can be tightened site-by-site as a follow-up; the
shape of the change is what matters here).
Verification:
- core 674/674 (incl. 6 new diagnostics tests covering silent default,
__hfDebug logging, legacy __HYPERFRAMES_DEBUG flag, handler hook,
handler-throws-doesn't-recurse, both-active)
- typecheck clean
- format / lint clean
- runtime IIFE rebuilds successfully (`bun run build:hyperframes-runtime`)
Refs Abhay's c2v eval — bundler artefacts now lint-clean with the
runtime body inlined.

feat(producer): auto-fallback screenshot capture for raf and iframes (#331)
* fix(core): drive adapter seeks when composition has no GSAP timeline renderSeek returned early when deps.getTimeline() was null, skipping the onDeterministicSeek call that drives all frame adapters (CSS, WAAPI, Lottie, Three.js). That meant compositions using any non-GSAP animation primitive froze on their initial frame during capture. Now we still quantize the seek time and fire onDeterministicSeek even without a timeline, so each adapter gets a chance to advance. GSAP compositions are unaffected — timeline-driven seek still takes the same path it did before.
