What

Sources that are (or contain) a uniform enumeration of like entries — machine inventories, error-code catalogs, customer rosters, product/price lists — used to come out as a representative subset with the tail compressed into one footnote (live example: the kelvarra showcase's organizations/instrument-works.md presses 5 "Sundries" products into a single [^s9]). The rules actively demanded that compression: the granularity floor prefers fewer dense pages, "essence, not structure" discards enumerable data, and meeting-minutes.md routes perennial reference tables to "ordinary facts" with no aggregate destination.

This PR adds the Registry page kind: one page per collection under the new wiki/registries/ folder, one bullet per entry with the entry's source-verbatim key in bold and its own citation at the finest available locator — and promotion: an entry that accumulates several independent cited facts (the unchanged granularity floor) moves to its own page of its own kind, its registry row becoming key + link + one-line gloss.

How

Almost all of it is rules text (the runtime program):

• New citadel/rules/genres/registry.md — applies-when test ("entries share one attribute shape, and a reader would ask is X on the list?"), completeness-over-compression (WRONG→RIGHT built on the Sundries defect), row shape + key identity + search-before-append, spreadsheet sheet-marker rule, promotion, per-row reconcile/Change-Log behavior, range-split (never topic-split) guidance, and an explicit negative list (Open Points, chat/event streams, code symbols, bibliographies, abbreviations).
• schema.md — Registry row in the type table, decision-procedure step 7 (before Concept, after Object — so a single rich machine still matches Object first, which is the promotion semantics), and a compact ## Registries format contract.
• core.md — two carve-outs: the floor limits pages, not rows; data rows are not code structure.
• meeting-minutes.md — perennial reference tables now route to the registry brief; tasks/reconcile.md keeps registry row lists as genre treatment; rules README.md indexed.

Two small code touches:

• okf.py — "registry": "registries" in folder_for_type (same commit as the rules text: the misc-fallback plus curate's resort detector would otherwise relocate every registry page each run).
• curate.py — the page_length_hard guidance is now type-aware: an oversized registry is told to split by entry range/subclass into sibling registries, never along topics (the detector itself is unchanged).

Everything else (per-folder index, viewer, type:registry search, MCP resources, curate resort) is data-driven and picks the new type up automatically.

New graded corpus: werkhof — and its committed showcase run

Per the project's "every capability is graded" pattern: corpora/werkhof/ (fictional maintenance firm, Werkhof Anlagenservice Brandt) — a 28-machine register (>200 lines ⇒ per-row lines A-B locators required), a 20-code fault catalogue (near-miss E-142 vs E-412, deprecated E-155→E-310), a 15-customer CSV (the data-not-code boundary), and a service report driving promotion, a dated HX-201 status supersession, attributed opinions, and a done-able open-items list (Open Points, never registry rows). Hidden answer key at .claude/skills/verify-corpus/werkhof/ground-truth.md; SKILL.md/CLAUDE.md/CI corpus floors updated.

The committed showcase wiki was generated by a real sonnet Mode A run under the new rules and graded against the full answer key — PASS on every guarantee (run block in docs/verify-corpus-backlog.md): three type: Registry pages carrying 28/28 machines, 20/20 fault codes, 15/15 customers, one citation per row with offline-verifying locators (lint locator issues: 0), promotion to objects//organizations/ with rows reduced to key + link + gloss, the status supersession as a dated trace, open items as ## Open Points, and mid-list keys (KP-011, E-420, K-009) retrievable top-1 through citadel search. check and lint both exit 0. The kelvarra Sundries defect is recorded and resolved as VCB-005 in the ledger.

Known limitation (documented in CHANGELOG)

A list source over CITADEL_MAX_SOURCE_CHARS (~300k chars) chunks through segment files whose line numbers rebase, so per-row lines A-B locators of such oversized lists are not offline-verifiable yet. v1 registries (tens to a few hundred entries) sit far below the threshold; the future fix is the _line_windows true-offset approach already used for audio/PDF.

Tests

• tests/test_okf.py — Registry routing (+ the misc-fallback pins stay).
• tests/test_curate.py — Registry in registries/ is not resort-flagged (while the same type mis-filed is), and the length guidance splits by range for registries, by topic for everything else.
• Full suite 1282 passed; ruff clean; all 10 showcase lints green locally; copilot-instructions regenerated (drift guard green).
