battles.contender_lens_assignments
Records which Connected Lens version is assigned to each contender slot, and stores the parameter values used at execution time.
| Column | Type | Description |
|---|---|---|
id | uuid | Primary key |
contender_id | uuid | FK → battles.contenders |
lens_id | uuid | FK → lenses.lenses |
version_id | uuid | FK → lenses.versions (null = use latest published) |
input_snapshot | jsonb | { "paramLabel": value } map — frozen parameter values substituted into [[param]] tokens at execution time. NOT NULL DEFAULT '{}'. |
assigned_at | timestamptz | — |
assigned_by | uuid | FK → lensers.profiles |
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).
