Ground Studio stack checks in pack.stack.tools

[Copilot]

Canonical issue

Linked by automation.

Outcome

Studio was still mixing transcript/catalog signals into the formation surface, which could surface Shopify-oriented stack UI on Cloudflare/x402 packs. This change makes Studio derive stack checks and formation tool chips from grounded pack.stack.tools, while continuing to show pack architecture and artifacts from the emitted pack.

const packFormation = studioPackFormation(selected?.videoPack);
const stackChecks = packFormation.checks;
const supplementalEntities = studioFormationSupplementalEntities(
  packFormation.tools,
  linkedSop?.entities,
);

Scope

• Included:
  • Ground stack checks in pack formation
    • OneLoopStudio now renders stack checks from packFormation.checks instead of re-filtering SOP checklist state inline.
  • Stop transcript-only tool bleed-through when pack tools exist
    • Added studioFormationSupplementalEntities(...) so grounded pack.stack.tools suppress transcript-only entity chips on the formation surface.
  • Regression coverage
    • Added focused tests for:
      • grounded pack.stack.tools driving Studio stack checks
      • transcript-only chips being hidden when pack tools are present
      • source-level Studio assertions updated to match the grounded path
• Explicitly excluded:
  • Linked SOP generation rules
  • pack extraction/schema behavior
  • unrelated billing/type-check failures already present on head

Risk

• Risk level: low
• Failure mode:
  • Studio could omit supplemental entity chips when a pack provides tools, or render no stack checks if the pack is malformed.
• Rollback:
  • Revert the OneLoopStudio/studio-pipeline-status changes in this PR.
