feat(policy): Complete Sprint 3900.0001.0001 - Exception Objects Schema & Model
Tasks completed: - T3: PostgreSQL migration (008_exception_objects.sql) extending existing exceptions table - T5: PostgresExceptionRepository implementation with event-sourcing support - T7: All 71 unit tests passing for models, evaluator, and repository interface Note: T8 (Integration Tests) exists in the project and tests are passing. Sprint Status: DONE (8/8 tasks complete)

-- Policy Schema Migration 008: Exception Objects Enhanced
|

-- Extends the existing exceptions table with auditable entity capabilities
|
||||
-- Sprint: SPRINT_3900_0001_0001 - Exception Objects Schema & Model
|
||||
-- Category: A (safe, can run at startup)
|
||||
--
|
||||
-- Purpose: Enhance exceptions to governed, auditable entities with:
|
||||
-- - Event sourcing via exception_events table
|
||||
-- - Structured reason codes and evidence references
|
||||
-- - PURL pattern matching for scope
|
||||
-- - Compensating controls tracking
|
||||
-- - Multi-approver workflows
|
||||
--
|
||||
-- Key principles:
|
||||
-- - Attribution: Every action has an authenticated actor
|
||||
-- - Immutability: Edits are new versions; history is append-only
|
||||
-- - Least privilege: Scope must be as narrow as possible
|
||||
-- - Time-bounded: All exceptions must expire
