How this rule is fixed

Not in the deterministic fixer pilot registry (stub or not yet wired). Use the After example below as the target state and remediate manually or extend pilot-registry.json.

Detection module: docs/design/ux-audit/deterministic-design-rules.md#det-spatial-hash_root. Scroll down for Before / After examples and Evidence and remediation steps.

Purpose

Kitchen Sink spatial primitives on spatial-effects.html are governed by three-letter hashes. This rule ensures each spatial hash present on a crawled page has complete marker pairing.

Passing signals

  • [data-ks-hash="Flp"] (and siblings) appear with matching hash="Flp" on the same root.
  • data-ks-type and data-ks-name present when emitted via ks_hash_attrs.

Failing signals

  • Spatial hash in DOM without paired attribute.
  • Incomplete marker rows in ksVisualHashReport.

Deterministic checks

Run tools/spatial-effects-verifier/run-all-oracles.mjs after build-showcase.py for behavior parity; this rule covers marker pairing only.
