+# Schema v1
+
+Acceptance files are markdown with YAML frontmatter.
+
+## Required frontmatter
+- `schema_version: "v1"`
+- `command`
+- `cols`
+- `rows`
+- `default_timeout_ms`
+- `generated_at`
+- `generator`
+
+Optional:
+- `cwd`
+
+## Scenario format
+Scenario header:
+- `## Scenario: <name>`
+
+Optional OpenSpec-style expectation narrative (human-readable):
+- `### Expectation` (or `### Expectations`)
+- `- **WHEN** ...`
+- `- **THEN** ...`
+- `- **AND** ...` (optional)
+- `- **SHOULD** ...`
+
+Supported steps:
+- `- expect: "<text>"`
+- `- press: "<key>"`
+- `- type: "<text>"`
+- `- wait_stable: true`
+
+OpenSpec narrative lines are ignored by the verifier parser; executable behavior is driven by the supported step lines.
+Any other non-empty line format is invalid.
