Mapping Anchors

Mandatory Reference Rule

• No downstream mapping spec may claim a keep, adapt, remove, or replace decision without citing at least one entry_id from the active baselined catalog.
• The active catalog for Spec 226 is astrodeck-226-baseline until a later refresh supersedes it.
• If a downstream spec references a section or component, it should also cite the owning page or surface context when that context changes the decision.

Recommended Reference Block

Use a concrete inventory block in downstream mapping specs such as specs/214-website-visual-foundation/, specs/215-website-core-pages/, or specs/217-homepage-structure/:

### Inventory References

- catalog_id: astrodeck-226-baseline
- selected_entries:
  - page.product
  - section.feature-grid
  - component.feature-item
- suitability_basis:
  - page.product: A / high
  - section.feature-grid: A / high
  - component.feature-item: A / high
- decision: adapt
- rationale: Keep the product-explainer structure but adjust copy hierarchy and visual density for the approved rebuild route.

Exception Path For Non-Candidate Decisions

• If a downstream surface has no direct candidate, write no direct candidate explicitly in the mapping spec and cite the closest rejected entry_id values plus the reason they were rejected.
• If an inventory entry is intentionally excluded, cite the entry_id, current suitability_class, and the concrete reason for exclusion instead of silently omitting it.
• If a downstream spec decides a current A or B entry should still be removed, that spec must document the higher-priority constraint that overrides the inventory suitability.

Refresh Rule Before The Next Mapping Cycle

• Refresh the inventory whenever the source primitive set changes under apps/website/src/pages, apps/website/src/components, or apps/website/src/layouts.
• Re-run the T002 discovery command from repo root and compare the resulting file list with inventory/catalog.md.
• If the primitive set changes, update the row-level inventory files, reconcile summary.md, and set catalog.md back to draft until review completes again.
