## What Kills two false-positive classes in the SDK shadow GSAP value-fidelity diff (`sdkShadowGsapFidelity.ts`). 1. **Float precision** — `numericEqual` compared exactly, so SDK-computed `3.0999999999999996` vs server `3.1` flagged as drift. Now a relative epsilon (`abs(a-b) <= 1e-6 * max(1,|a|,|b|)`); real `2` vs `1` still flags. 2. **Selector-form divergence** — `[data-hf-id="X"]` (SDK writer) vs `.class`/`#id` (server writer) for the same element produced phantom `present`/`absent` pairs. `makeSelectorResolver` now keys tweens by resolved element (incl. nodes with no `data-hf-id`), unifying the forms. ## Why Surfaced by production SDK-shadow parity telemetry — `gsap_fidelity` was the noisiest real-traffic op; both are diff-harness artifacts, not SDK drift. ## Tests Epsilon (clean + real-drift) + selector-unification for `#id`/`.class`/`[data-hf-id]`. 🤖 Generated with [Claude Code](https://claude.com/claude-code)
