+feat(scenarios): the deterministic scenario scorer lives in `@objectstack/scenarios` and judges capability tags, agent-action exposure, write outcomes and per-persona answers against a loaded card
+
+Clause-②: no
+Metadata-protocol: none
+
+- **`@objectstack/scenarios/score`** (private, unpublished): the entry the scenario runner calls. `scoreCardArtifact(card, artifact)` scores a built `dist/objectstack.json`; `gradeCardOperation(card, operationId, observation)` judges an observed write against its declared outcome; `gradeCardAnswer(card, { question, persona?, turn })` grades an agent's answer against the loader's computed truth for that persona. Each takes a card the loader returned, and the graders read the card schema's own types.
+- **The scorer moved here from `@objectstack/cli`.** That covers the structural shape score, the artifact-to-graph reader and the Run grader, which were never released from the CLI. It now also carries:
+  - **capability-tag checks**: a closed table of nine tags, listed in the package README. A tag outside it, or a row with nothing in the card to judge, is reported `unscored` and counted nowhere;
+  - **agent-action exposure**: each declared action exists on its object, carries `ai.exposed: true` and, where the card says it asks first, `ai.requiresConfirmation: true`. A missing action fails;
+  - **a write-operation grader**: `applied`, `refused` or `pending_confirmation`. An unobserved fact fails;
+  - **per-persona Run grading**: a `withheld` truth is must-not-reveal, and an all-rows figure outside a scoped persona's rows is a leak.
+- **`@objectstack/cli`**: `MetadataEvalCase` is now declared in `corpus.ts`, beside the golden corpus it types, and `metadata-eval.ts` re-exports it under the same name. No behaviour change, no new flag and no new package-entry export. The CLI carries no scenario code.
+
+No model call anywhere.

+
+## Scoring a run against a card — `@objectstack/scenarios/score`
+
+Every function takes a card the loader returned, so it judges against the loader's computed
+truths and declared outcomes:
+
+```ts
+import { gradeCardAnswer, gradeCardOperation, scoreCardArtifact } from '@objectstack/scenarios/score';
+
+scoreCardArtifact(card, artifact);                 // a built dist/objectstack.json: expect, tags, agent actions
+gradeCardOperation(card, 'remove_chen', observed); // an observed write against its declared outcome
+gradeCardAnswer(card, { question: 'account_count', persona: 'sdr', turn }); // an agent's answer
+```
+
+- `scenario-score.ts` — `expect` scored by exact name and by shape; `scenario-graph.ts` reads
+  the artifact into the graph both score.
+- `scenario-tags.ts` — the capability-tag checks and the agent-action exposure check (each
+  declared action exists on its object, carries `ai.exposed: true`, and carries
+  `ai.requiresConfirmation: true` where the card says `confirm`; a missing action fails, never
+  skipped).
+- `scenario-operation-grade.ts` — an observed write against `applied` / `refused` /
+  `pending_confirmation`; a fact the observation does not carry fails.
+- `scenario-run-grade.ts` — an answer graded on correct / cited / leaks, per persona against
+  that persona's truth; a `withheld` truth is must-not-reveal.
+
+### The closed capability-tag table
+
+A card's `capabilities` tag scores only when it is one of these, spelled exactly. Any other
+tag is reported **`unscored`** — listed, counted neither as passed nor in the total, never a
+pass — and so is a row whose card gives it nothing to judge (a field-permission tag on a card
+whose personas hide no field). To score a new tag, add a row to `CAPABILITY_TAG_CHECKS` with a
+discrimination test; ⛔ never match by area prefix.
+
+| Tag | Passes when the built artifact… |
+|:---|:---|
+| `records-forms.lookup` | carries a lookup field, and every lookup field resolves to an object the build or the platform serves |
+| `records-forms.master-detail-inline-edit` | has every master-detail field resolving, and one of them edited inline on its master (`inlineEdit`) |
+| `records-forms.roll-up-summary` | carries a roll-up summary, each reading a child object that relates back and, unless it counts, a child field that exists |
+| `records-forms.select-options` | carries a single-choice option field (`select`, `radio`), each offering at least two options |
+| `access-security.field-permissions` | denies (`readable: false`, in a permission set) every field a card persona hides, and has that field |
+| `access-security.row-scope` | keeps every object a persona's `scope` names private (owner-scoped), or derived from its master |
+| `approvals.approval-flow` | carries an approval (a flow with an Approval node), each bound to an object it serves, one bound to an object the card names |
+| `automation.record-triggered-flow` | carries a record-triggered flow, each bound to an object it serves, one bound to an object the card names |
+| `dashboards.widget-measures` | carries a dashboard widget with a measure, and every widget measure resolves on the dataset it binds |
