Data-bound sandbox core

SPEC-093 core — the build-time data channel from the registry into a sandbox. The registry's third render target (HTML via collection, SVG via aggregate, arbitrary client-side here). Independent of the SPEC-092 track: flat/tree shapes work over the page/pageTree data that exists today.

    plan: v0.21.0 work breakdown — SPEC-092 + SPEC-093 (WORK-383..390)

Decisions (locked)

  • Binding: a data attribute carrying a SPEC-070 field-match query (+ optional data-fields projection, data-shape). Resolved at build by a step sibling to collection-resolve.
  • Injection: an inline <script type="application/json"> is the canonical transport (handles large payloads; data-attributes don't), exposed to the iframe as a frozen global window.RF_DATA, alongside the existing design-token/theme globals. Reuses the proven token-injection rail in behaviors/.../sandbox.ts.
  • Shapes (this item): flat (entity array) and tree (nest by parentUrl). graph is WORK-390.
  • Fallback is mandatory and authored for v0.21.0 (auto-fallback deferred): a data-bound sandbox with no authored collection/aggregate fallback warns.
  • Bounded payload: a configurable cap (records/bytes) — exceed → warn + truncate.

Acceptance Criteria

  • A sandbox accepts data (+ data-fields, data-shape=flat|tree); the query resolves at build to a projected, serialisable result injected as window.RF_DATA + the JSON <script>.
  • Works across both the html adapter and the sveltekit renderer (the injected data survives serialization — follow the design-token rail).
  • Payload over the cap warns and truncates; a data-bound sandbox without an authored fallback warns.
  • Tests for resolve, projection, both shapes, the cap, and the fallback warning.
