Plan: phase5/evidence-schemas

Objective

Create Pydantic schemas for the evidence API: create, update, response, and list response.

Schemas

EvidenceCreate

• assessment_practice_id: str (required)
• title: str (required, 1-256 chars)
• description: str | None (optional)
• file_name: str | None (optional, for metadata)
• file_size: int | None (optional, bytes)
• mime_type: str | None (optional)

EvidenceUpdate

• title: str | None
• description: str | None
• file_name: str | None
• file_size: int | None
• mime_type: str | None

EvidenceReview

• review_status: Literal["accepted", "rejected"]

EvidenceResponse

• All model fields + created_at/updated_at
• from_attributes = True

EvidenceListResponse

• items: list[EvidenceResponse]
• total: int

ReviewStatus type

• Literal["pending", "accepted", "rejected"]

Files

• NEW: cmmc/schemas/evidence.py
• NEW: tests/test_evidence_schemas.py

Pattern

Follow existing schema conventions from cmmc/schemas/assessment.py: - Field() with validation constraints - model_config = {"from_attributes": True} on response models - Separate Create/Update/Response classes
