| 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 the survey in status/model-inventory-2026-07-02.md, 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).
