+# Action schema
+
+This is the portable execution contract for version `1.0`.
+
+## Root object
+
+| Field | Type | Requirement |
+|---|---|---|
+| `schema_version` | string | Must be `"1.0"` |
+| `source` | string | Media filename or stable source identifier |
+| `actions` | array | One or more executable actions |
+
+The root contains only these fields. Notes, questions, and summaries belong
+outside the JSON block when a human-facing response is allowed.
+
+## Cut action
+
+```json
+{
+  "kind": "cut",
+  "start": 0.0,
+  "end": 2.5,
+  "reason": "Abertura sem conteúdo editorial."
+}
+```
+
+- `kind` is exactly `"cut"`.
+- `start` and `end` are finite seconds in the original source media.
+- `start` is inclusive and `end` is exclusive.
+- `start` must be smaller than `end`.
+- The interval must be within the known source duration.
+- Two cut intervals may not overlap; adjacent intervals should be merged.
+- `reason` is required and must identify the editorial basis without claiming
+  facts absent from the timeline.
+
+The executor removes every cut interval. The editor therefore derives cut
+intervals from the selected material rather than listing selected intervals as
+cuts.
