M6-T03: add pricing profile framework + strategy registry
- app/integrations/pricing: profiles.py (pydantic ManualProfile/TibberProfile, load_profile/list_profiles/validate_values), manual.yaml + tibber.yaml (structure-only, no price values), strategies.py (register/get_strategy, manual dual-tariff + tibber strategies, all Decimal). - tibber strategy matches nearest tibber_price with starts_at <= t0. - tests for profiles + strategies (hand-checked dual-tariff & tibber math).

This package provides:
|

|

- ``profiles``: Pydantic models describing the structure of pricing profiles
|

(``ManualProfile`` / ``TibberProfile``), YAML loaders, and contract-values
|

validation (``load_profile`` / ``list_profiles`` / ``validate_values``).
|
||||
- ``strategies``: A lightweight registry of price-calculation strategies
|

(``register_strategy`` / ``get_strategy``), with built-in implementations for
|
||||
the ``manual`` (fixed dual-tariff) and ``tibber`` (dynamic API) kinds.

"""Pricing profile loader, validator, and contract-values checker.
|
||||
|
||||
A *pricing profile* is a YAML file that describes the **structure** of an energy
|
||||
contract — which fields exist, their units, and which have defaults. Actual
|
||||
pricing values (the numbers the user fills in via the UI) are stored in the DB
|
||||
as ``EnergyContractVersion.values`` (a JSON blob) and must conform to the
|
||||
corresponding profile's structure.
|
||||
|
||||
Profiles live in ``app/integrations/pricing/profiles/<kind>.yaml`` and are
|
||||
located at runtime relative to *this file* (not CWD), matching the pattern
|
||||
established by the Modbus profile loader.
|
||||
|
||||
Design notes
|
||||
------------
|
||||
- **Purely data + functions** — no abstract base classes or inheritance.
|
||||
- Two Pydantic models — ``ManualProfile`` and ``TibberProfile`` — capture the
|
||||
different structures of the two supported kinds. A thin union dispatcher in
|
||||
``load_profile`` picks the right one.
|
||||
- ``validate_values(kind, values)`` fills in fields that carry a ``default`` and
|
||||
raises ``ProfileValidationError`` for missing required fields or wrong types.
|
||||
- All errors are subclasses of built-ins so callers need not import this module
|
||||
just to catch them.

"""Price-calculation strategy registry and built-in implementations.
|
||||
|
||||
A *strategy* is a plain function registered under a ``kind`` string. Given
|
||||
per-register kWh deltas, the period start time, the active contract-version
|
||||
values, and a DB session, it returns a result dict with:
|
||||
|
||||
{
|
||||
"import_cost": Decimal, # total cost of electricity drawn from grid
|
||||
"export_revenue": Decimal, # total revenue from electricity fed to grid
|
||||
"net_cost": Decimal, # import_cost − export_revenue
|
||||
"pricing": dict, # snapshot of the price inputs used (for auditing)
|
||||
}
|
||||
|
||||
**Import and export are kept separate throughout** — net_cost is only derived
|
||||
at the end. This supports the Dutch no-netting rule (saldering afgebouwd).
|
||||
|
||||
**All monetary arithmetic uses Decimal** converted via ``Decimal(str(x))`` to

avoid float binary rounding errors.

Design notes
|

------------
|
||||
- **Purely data + functions**: no ABC, no class hierarchy. A ``dict``-based
|
||||
registry is the simplest structure that supports the two current kinds and
|
||||
leaves the door open for future additions (e.g. ``octopus``, ``frank``).
|
||||
- ``deltas`` is a plain dataclass ``PeriodDeltas`` — typed, but no ORM.
|
||||
- Tibber strategy queries ``TibberPrice`` directly from the session; it does not
|
||||
call the Tibber API (that is T05's job).
