+/**
+ * Pin for WHAT the published pointer row for `ai/solution-blueprint.zod.ts`
+ * names — plan-first authoring, not a list of the symbols it happens to export.
+ *
+ * `build-skill-references.ts` describes each source by the module's own doc
+ * block (`lib/file-description.ts` selects it: top-level, in the header zone,
+ * documenting no symbol), and falls through to `Exports: …` when no block
+ * qualifies. This file HAD its header — ADR-0033 §4, the `apply_blueprint`
+ * expansion — but a single blank line was all that separated it from
+ * `const SNAKE_CASE`, so TSDoc's own attachment rule made it that regex
+ * constant's documentation and the selector disqualified it. The published
+ * index therefore stated a true fact ABOUT the file and nothing about its
+ * SUBJECT, on the very row whose job is to route an agent to the source for
+ * exact field shapes.
+ *
+ * Same root cause as #14441 pointing the other way: there the wrong block was
+ * published, here the right one was suppressed and a machine-generated list
+ * took its place. Both are the header-zone selector deciding against a header
+ * a human wrote — and in this direction the selector was RIGHT under its own
+ * rule, so the repair is in the source, not in the selector.
+ *
+ * No generator can see this class. `check:skill-refs` and `check:docs` compare
+ * the artifact against the generator, and the generator reproduced the
+ * selector faithfully — a generator-only check PASSES on the defect. So pin
+ * the fact the artifact must state, not the pipeline that states it.
+ *
+ * Two legs that fail DIFFERENTLY, which is why both exist. The SOURCE leg reds
+ * the moment the separator between the header and `SNAKE_CASE` is removed —
+ * no regeneration needed. The CORPUS leg stays green through that (it reads
+ * checked-in bytes, which only move when someone regenerates) and reds on the
+ * state this card found: an index regenerated from a file whose header no
+ * longer qualifies. MEASURED both ways in the fix's reverse verification.
