Slice 1 of the #1157 build. The FE creates a Scenario and passes only its id to the pipeline; the Modelling stage reads it back here. - domain/modelling/scenario.py: thin `Scenario(id, goal, goal_value, budget, is_default)` — the slice the stage uses today (goal/budget for the Optimiser later; is_default drives plan.is_default). No phases (ADR-0005); legacy file-path/aggregate columns not modelled. - infrastructure/postgres/scenario_table.py: `ScenarioRow` SQLModel mirror of the live `scenario` table (ADR-0017), declaring only the read columns; goal mapped as its string value. - ScenarioPostgresRepository.get_many(scenario_ids) -> list[Scenario]: bulk read, input-order-preserving, raises on a missing id. The method shape lives on the concrete repo for now; it is promoted to an @abstractmethod on the port when the real orchestrator is wired and the bare-stub instantiations retire (keeps the stubbed Modelling wiring composing meanwhile). 2 tests, pyright strict clean.

"""Scenario — the named retrofit brief the Modelling stage scores against.

|
Built by a user in the scenario-builder UI and persisted before any modelling
|
|
fires; the pipeline is handed only its id and reads it back via a
|
|
`ScenarioRepository`. This is the thin slice the Modelling stage uses today:
|
|
the goal + budget that the Optimiser will consume (#1160) and `is_default`
|
|
(which drives `plan.is_default`). The legacy file-path / portfolio-aggregate
|
|
columns are not modelled. Carries no phases — multi-phase is deferred
|
|
(ADR-0005). See CONTEXT.md.
