A two-act session across the AICV and sunshine-fm repos — schema work, taxonomy audit, five guide-builder tasks, and architecture documentation. Context compacted mid-session; both halves shipped clean.
Started with SCHEMA v1.1 — added target_type to the connection spec with a documented null allowance for taxonomy-reference connections where zone and subcategory aren't yet ledger entries. Minimal, correct, doesn't encode anything that isn't real. Committed as dd1e71f.
The taxonomy audit followed — a read-only pass on TAXONOMY.md that found the valley-wide bucket holding five semantic subclasses and 28 of 29 nodes on forbidden variant values. That finding became AUDIT-2026-04-20-taxonomy.md, committed as a durable artifact at 1691cdf. The full arc of that work is documented in the companion entry from earlier today.
Also before compaction: deleted ListBadge.astro, extracted src/lib/display-maps.ts with three pages now importing from it, added listNumber to the Zod schema, and deduped the sameAs array in JSON-LD. Four tasks, all mechanical, all clean.
After compaction, Task 5 — the SiteChrome mobile nav. Hamburger button visible below 768px, full-screen canvas overlay, Barlow Condensed lowercase stacked links, X button plus Escape to close, focus trap, and ARIA attributes throughout. Build clean, zero warnings.
Added civic-institution as a new category: Zod enum entry, Organization mapping in Schema.org JSON-LD, display label and gradient in display-maps.ts. One consistent change across all the right places.
Appended "Why this architecture is simple (and stays simple)" to guide-builder/README.md. Appended the relationship between the guide-builder and the SunshineFM Guide to aicv-playbook/CLAUDE.md. Replaced the minimal CLAUDE.md stub with full operating context. Added an emphatic warning comment above the .catch() block in index.html — the newsroom cards are active content, not a fallback, and that distinction needs to survive future sessions.
Created _TEMPLATE.md and _CATEGORY_FIELDS.md in src/content/guide/ as authoring references for whoever writes content next — complete frontmatter template and per-category categorySpecific conventions in one place.
