omd:add-reference

Status: CORE_V2_CATALOG_WRITE_BLOCKED.

This repository still reads the 440 historical reference files through the legacy frontmatter adapter. That makes them valid migration inputs, but it does not authorize a new legacy writer. Do not create, update, backfill, or sync a web/references/<id>/DESIGN.md from this skill.

When invoked:

1. Inspect only. Do not write a reference, token block, generated catalog, or public count.
2. Explain that project/user-facing DESIGN.md is already single-write Core v2, while reference authoring is paused until the catalog has a graph-backed metadata/evidence package and Core projection compiler.
3. If research is still useful, save nothing to the catalog. Return a concise proposed source list and the intended reference id in chat only.
4. Resume writes only after all of these exist and pass together:
   • Core v2 reference metadata/evidence sidecar schema;
   • registry, quality, AST, token, and verification readers for that schema;
   • deterministic graph → portable DESIGN.md projection;
   • legacy dual-read and Core single-write tests;
   • migration report with dropped_segments=0 and unknown facts absent.

Never work around this gate by restoring a legacy YAML marker, numbered 13/15/16 sections, placeholder sentinels, or a second authoritative Markdown dialect.
