## Core tables

| `input_snapshot` | jsonb       | `{ "paramLabel": value }` map — frozen parameter values substituted into `[[param]]` tokens at execution time. `NOT NULL DEFAULT '{}'`. |
| `assigned_at`    | timestamptz | —                                                                                                                                       |

**`input_snapshot` semantics:** when a lens version declares required `[[param]]` placeholders, the wizard (Step 7) or CLI collects values and stores them here. At execution start the system calls `renderLensWithSnapshot(templateBody, input_snapshot, versionParams)` to produce the final prompt. If any required parameter is absent, execution is blocked with a descriptive error.

### `battles.rubrics` and `battles.rubric_criteria`

Optional evaluation frameworks.

**`rubrics`** — metadata: `id`, `creator_lenser_id`, `title`, `description`, `is_public`, `version`.

**`rubric_criteria`** — individual criteria within a rubric: `id`, `rubric_id`, `ordinal`, `title`, `description`, `weight` (default 1.0).
