Two resolver-shadow noise classes from production telemetry: - Cross-file guard (0.7.41: 479 false element_not_found from ONE session): the dom-edit tripwire ran for edits targeting a different file than the session models. The cutover gates already decline these (wrongCompositionFile); the tripwire now skips the same way — no event, no attempt, since the op structurally cannot cut over. - Stale-session disambiguation (0.7.48: 53 animation_not_found across keyframe ops): the GSAP panel derives animationIds from the CURRENT on-disk script every render, while the session's parsed id space dates from the last reload. Position edits shift every selector-method-position id, so panel ops landing before the reload target ids the session has never seen. Parser id-space parity was verified across legacy/acorn read/write paths (9 script shapes) — the ids agree; the session is just behind. On a miss with a reader wired, recordAnimationResolverParity now re-parses the on-disk file: a hit there = stale session (suppress); a miss there = genuine divergence, tagged diskChecked so the dashboard can trust the class. Attempt-counter machinery moved to sdkResolverAttempts.ts (600-LOC studio file gate); re-exported from sdkResolverShadow for API compat. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
