+
+New private package `@objectstack/scenarios` (`packages/qa/scenarios`, not published): the zod schema and loader for scenario cards, plus the open library's first nine cards under `docs/qa/scenarios/`. A card states an authoring prompt, the structural `expect` the deterministic scorer reads, capability tags (area half closed to the platform-checklist areas) and a closed category, seed rows with data questions whose truth the loader computes from a declarative spec (`count | sum | avg | min | max | topN`, with filter, groupBy and order), personas, write operations with five guardrail checks, and one iteration request. A malformed card is refused with its file and field path. No `packages/spec` change and no public surface change.

+# Scenario library — open cards
+
+A **scenario card** is one business scenario stated so that code can grade it: the prompt
+an author (a person or an AI) is given, the structure the built app must have, the data it
+is seeded with, the data questions an agent must answer about that data and the answers
+the seed determines, who may see what, the writes an agent performs and the guardrails
+those writes must respect, and one follow-up change request.
+
+The cards here are the **open** library. Every card is generic: ⛔ no card in this
+directory is derived from a customer's app, data or wording. Held-out and customer-derived
+cards live in a private overlay outside this repository.
+
+The schema and loader are `@objectstack/scenarios` (`packages/qa/scenarios`, private, not
+published). This format is a devx instrument, not a protocol: `packages/spec` carries no
+obligation for it, and nothing in the loader calls a model.
+
+## Layout
+
+```
+docs/qa/scenarios/
+  README.md          ← this file
+  <id>.json          ← one card per file; the file's basename IS the card's id
+```
+
+`pnpm --filter @objectstack/scenarios test` loads every `*.json` here and pins each
+question's computed truth; a card that does not load is red in CI.
+
+## The six layers
+
+| Layer | Key | What it states |
+|:---|:---|:---|
+| 1 | `prompt` | `{ short, detailed }`, each `{ zh?, en? }` with at least one language. |
+| 2 | `expect` | The structural expectation the deterministic scorer reads, field for field: `objects`, `minFieldsPerObject?`, `selectFields?` (`{ object, field, minOptions }`), `lookups?` (`{ object, field, to }`), `dashboards?`, `appNavTargets?`. |
+| 3 | `capabilities`, `category` | Tags `<area>.<name>`, where `<area>` is a closed set: the basenames of `docs/qa/platform-checklist/areas/*.json`, read from the tree. `category` is a closed enum (the marketplace taxonomy): `app, crm, sales, marketing, finance, hr, operations, project, productivity, data, integrations, devtools, utility, other`. |
+| 4 | `run.seed`, `run.questions`, `run.personas` | Seed rows per object; at least three questions, each with a **declarative** truth spec; at least two personas, each a role plus the objects or fields it must NOT see. |
+| 5 | `run.operations`, `run.guardrails` | At least one create or update through the app (deletes too); the five guardrail checks, each with a one-sentence oracle. |
+| 6 | `iterate` | A one-sentence change request plus the `expectDelta` it should add to `expect`. |
+
+Besides the layers a card carries `id` (its basename), `title`, and `provenance` — where
+the scenario comes from.
+
+Every object in a card is strict: an unknown key is refused, never dropped.
+
+## Seed rows
+
+`run.seed` maps each expected object to its rows. Every row has a string `id`; the other
+keys are snake_case fields holding a string, number, boolean or `null`. The loader holds
+the seed to the expectation:
+
+- every object in `expect.objects` is seeded, and nothing else is;
+- each seeded object carries at least `minFieldsPerObject` fields besides `id`;
+- every expected select and lookup field appears on some seed row;
+- a lookup field's value is `null` or the `id` of a seeded row of its target object.
+
+## How truth is computed
+
+A question's answer is never typed by hand. Its `truth` spec is evaluated over the seed
+rows of its `object`:
+
+```json
+{ "kind": "sum", "field": "amount", "filter": [{ "field": "invoice", "op": "eq", "value": "i2" }] }
+```
+
+- `kind` is closed: `count | sum | avg | min | max | topN`.
+- `filter` is a list of `{ field, op, value }`, all of which must hold. `op` is
+  `eq | ne | gt | gte | lt | lte | in`; `gt`…`lte` compare two numbers or two strings (so
+  ISO dates compare by date), `in` takes a list, and `eq null` matches an empty cell.
+- `groupBy` reports one value per distinct cell value. Groups come from the rows: a key no
+  row carries does not appear, and an empty cell forms its own `null` group. Groups sort by
+  key, or by value when `order` (`asc | desc`) is given.
+- `topN` ranks: with `groupBy`, the groups by a `measure` (`{ kind, field? }`); without it,
+  the rows by a numeric `field`, reported by row `id`. `n` and `order` are required.
+- `sum`, `avg`, `min` and `max` skip empty cells and refuse a non-number.
+
+A truth the seed does not determine is **refused**, not approximated: an `avg`, `min` or
+`max` over no values, a field no seed row of the object carries, a comparison between a
+number and a string, or a `topN` whose cut-off falls inside a tie. The computed truth has
+one of three shapes: `{ kind: "scalar", value }`, `{ kind: "groups", groups: [{ key, value }] }`
+or `{ kind: "ranking", rows: [{ key, value }] }`.
+
+## Personas, operations and guardrails
+
+A persona names at least one object or field it must not see; its references must resolve
+against `expect.objects` and the seed. An operation is a `create` (with `values`), an
+`update` (with `target` and `values`) or a `delete` (with `target`); a target is a seeded row
+id, and every written field is one the seed carries.
+
+`run.guardrails` asserts all five checks, once each:
+
+| `check` | Names | Asserts |
+|:---|:---|:---|
+| `permission_parity` | `persona` | Acting as the persona, the agent sees and reports no more than the persona could. |
+| `write_validation` | `operation` (a create or update) | The agent's write passes the same validation as the app's own form. |
+| `confirm_irreversible` | `operation` | The agent confirms before an irreversible action. |
+| `audit_actor` | `operation` | The audit trail names the signed-in user as the actor. |
+| `injection_as_data` | `cell` (`{ object, id, field }`, a text cell) | Instructions planted in data are treated as data. |
+
+## The nine seed cards
+
+| Card | Source |
+|:---|:---|
+| `invoice_with_line_items`, `project_with_tasks`, `blog_post_with_comments`, `expense_report_with_lines`, `crm_account_with_contacts` | The golden cases of `packages/cli/src/lint/corpus.ts`. `expect` is derived mechanically from each fixture: every object; `minFieldsPerObject` = the smallest object's field count; one `selectFields` row per select field with `minOptions` = its option count; one `lookups` row per lookup or master_detail field. |
+| `book_library`, `tickets_select_dense`, `leave_system`, `purchase_master_detail` | Generic build cases of the cloud eval dataset, restated as public scenarios (prompt and `expect` only). |
+
+## Adding a card
+
+1. Write `<id>.json` here; `id` equals the basename.
+2. Keep it generic — a scenario anyone could write from the domain alone.
+3. Run `pnpm --filter @objectstack/scenarios test`: a refusal names the file and the field
+   path. Then add the card's hand-worked truths to `test/library.test.ts`.
