Corpus items invisible on person cards; coverage unassessable

The symptom (screenshot-confirmed, 2026-07-24)

On the Lumina card → People → Jamie Merisotis: “Corpus items 3” — a count, a 🔍, a ➕, and no list. The operator can add a fourth item without ever seeing the three that exist. Links render in full; corpus doesn’t.

Why this happened (a Phase 4 contract decision, now disproven)

organization.affiliations deliberately returns personal_corpus_count only — the Augment-from-DB spec’s Phase 4 scoped entry-listing out (“entries ride affiliation.detail in a later pass if the operator wants it”). The operator wants it. First real session with the surface proved count-only wrong: assuring corpus coverage is a core purpose of the workbench, and you can’t assure what you can’t see.

Two layers to the fix (jotted)

1. Per-card visibility (the direct fix). Either extend organization.affiliations to return personal_corpus[] entries (payload is small; 8MB NATS ceiling is nowhere near), or lazy-fetch per-person on expand via the existing affiliation.detail (already returns person.personal_corpus — zero new verbs). Render with the same list shape as links: kind badge · host/title · date. Same question applies to content_items hydration — org corpus rows render bare URLs today; titles live in the ledger unused.
2. Coverage assessment (the real job). A view that answers “which relevant orgs/people have NO corpus items (or none newer than X)?” — a sortable roster of entities with link/stream/corpus counts, thin rows, red-zero highlighting. Could be a lens over the canonical layer, a workbench mode, or a didi verb (/coverage). This is what “hard to assess” actually asks for; the per-card fix alone doesn’t answer it.

Open questions

• Eager (extend affiliations reply) vs lazy (affiliation.detail on expand) — lazy ships with zero service changes; eager is one query.
• Do corpus rows want titles from content_items (a join) or is URL+kind enough for v1?
• Where does the coverage roster live — and does it fold into the usability-iteration sweep alongside [[No-Component-Library-UI-Improvised-Not-Component-Based]]?
