Class ModelScoringActionGenerator

The canonical scoring param set, mirroring the parent Score Record Set action: ModelID (pre-seeded for this model), Scope, WriteBack, plus the five output params. Kept DRY via a small spec list.

Load + delete all MJ: Action Params rows for the given action.

Find-or-create the MJ: Action Categories row that groups all per-model scoring actions. Idempotent (find by Name first). Returns its ID, or null if the category couldn't be created (logged).

Load an Action by exact Name (idempotency lookup), or null.

Load the canonical parent Score Record Set Action — the top-level row (ParentID null) whose DriverClass is the scoring driver. Returns null (caller logs + bails) when it's missing.

The model's human label — its pipeline name, or the model id when unset.

The model's version, defaulting to 1 when unset.

Delete the action's existing params and recreate the canonical scoring param set (matching the parent's contract). The ModelID input is pre-set to this model's id via DefaultValue so omitting it scores with this model.

Human-readable description naming the model label + version.

Deterministic Action Name: Score with <label> v<version>. The model has no Name column; its human label is the producing pipeline's name (the denormalized Pipeline view field), falling back to the model id.

Find-or-create the per-model scoring Action by its deterministic Name and apply its fields. The child reuses the parent's DriverClass (composition) and links via ParentID. Returns the saved row, or null on save failure (logged).
