A survey of the twenty notebooks on disk found general facts that no tracked page stated; the maintainer struck the weak rows and the rest are written into their owning pages in each page's own words. The design-system page gains the hidden-navigation figures that replaced a dangling survey pointer, the reason the anatomy is parts and lint, the record-table grouping and single-tint rules, and when a surface earns row editing. The first-contact process gains a code-verification phase, the transcript lane for models without vision, the three kinds of honesty-audit drift and the click-path guardrail. The operator conventions gain guards-before-writes, error state over empty state, copy that states the real effect, toasts that report counts and the PostForm rule. The Stripe, FedWiki, identifiers, IA, testing, model and environment pages each gain their facts, the integration guide stops telling authors to hand-write a page title, issues.md logs the placeholder security contact, milestones.md records the Codeberg terms clause and CONTRIBUTING.md notes that the module path is the forge URL. One claimed fact was checked against the code and not written: the mass-mutation preview does not run the commit loop in a rolled-back transaction.

| Domain Model Cards |
|
One card per domain model: purpose, invariants, dimensions, drift traps, and open questions, each claim cited to the migration, file, or decision that enforces it. |
Domain Model Cards
Each card in this directory describes one domain model as it is actually built, so a maintainer can modify that model without re-deriving its rules from migrations, specs, and decision documents. The cards are the descriptive home for the as-built models; the normative record — the designed schema, the decision log, the numbered design documents, and the glossary — lives in the synced design/ directory (Decision 141, design/documents/doc-43-schema-topology-and-documentation-division.md). Migrations are the ground truth for as-built claims.
The catalog was motivated by a 2026-07 inventory of the console's domain models, which traced the majority of a 56-finding UX audit to model-attributable causes: rules that lived only in prose, invariants enforced nowhere, and dimensions that were easy to conflate because no single page named them side by side.
The cards
- Product / catalog — how capabilities are packaged, priced, and sold; the dissolved kind taxonomy and the shape views that replaced it.
- Payments and Billing — billing accounts, subscriptions, invoices and payments projected from Stripe, scheduled changes as intent, and the reconciler.
- Plan Ladders and Transitions — ranked tiers, who occupies which rung, the append-only audit, and the conferral functions as sole writers.
- Entitlements — resource keys, sets and rules, grants as decrees, provisions as delivery, and the materializer.
- Resource Pools — the per-organization container: workspace assignments, the two resolution directions, and pool-grain usage.
- Providers and Integrations — the registry, boot-time manifests, resource-key ownership, and the shared substrate.
- Domains Registry — claims as subtree ownership, placements as the only thing that serves, and the anti-abuse ledger.
- Identity, Organizations, and Workspaces — users vs persons, the containment ladder, org types as policy, and first-login provisioning.
A new domain model is not considered documented until its card exists and is listed here.
Card anatomy
Every card has four sections in this order:
- Purpose — what the model owns and why it exists, in plain present tense.
- Where this lives — a map of the model's pieces: each table, view, function, and code file, with one line saying what it is. Locations live here, not scattered through the body.
- Invariants — the rules the model guarantees, one per numbered entry so reviews can cite "invariant 3". Each entry carries an enforcement tag matching the actual mechanism: [db] means the database schema rejects violations outright; [db-code] means the database functions are written to uphold the rule, so reviews must protect it when they change; [app] means only application code upholds the rule, so new code paths must uphold it too.
- Dimensions — the orthogonal axes a maintainer must hold simultaneously, each defined where it is named.
Cards describe the model as it is today, for a reader who knows nothing yet. That means: no history, no decision numbers, no change narrative in the body — a card introduces every table, column, view, and concept before or where it first uses it. Drift between design and code, open questions, and other bookkeeping live in status/issues.md under "Model documentation", not in the cards.
Style contract
Card prose follows these rules, and edits are reviewed against them:
- Write for someone with zero context: never assume the reader knows a term, a table, or an internal codename you haven't introduced.
- Name the agent: state what acted and what it acted on.
- Give each verb its own object; do not let one object serve two verbs.
- Connect clauses with explicit causal or temporal words (because, so, when, after) — never with a bare comma.
- Replace every metaphor or compressed phrase with the literal claim it stands for.
- Give every count or statistic its denominator.
A change that alters an invariant, dimension, or map entry recorded on a card must update that card in the same change (see openspec/specs/model-catalog/spec.md once this change archives).
