arch-06) +- Marketplace infrastructure (deferred to marketplace-01/02) +- Breaking changes to existing module interfaces (backward compatible formalization) + +## Decisions + +### Decision 1: Protocol over Abstract Base Class + +**Choice:** Use `typing.Protocol` for `ModuleIOContract` instead of ABC + +**Rationale:** +- Structural subtyping: Modules don't need explicit inheritance +- Duck typing: Existing modules work without modification (opt-in formalization) +- Static type checking: basedpyright verifies compliance without runtime overhead +- Flexibility: Modules can implement subset of operations (e.g., sync-only modules) + +**Alternatives considered:** +- ABC with abstract methods: Requires explicit inheritance, breaks existing modules +- No protocol: Informal contracts are error-prone and block marketplace verification + +### Decision 2: Four Core Operations + +**Choice:** Define 4 required operations: `import_to_bundle`, `export_from_bundle`, `sync_with_bundle`, `validate_bundle` + +**Rationale:** +- **import_to_bundle**: External format → ProjectBundle (e.g., ADO work items → features) +- **export_from_bundle**: ProjectBundle → External format (e.g., features → ADO work items) +- **sync_with_bundle**: Bidirectional sync with conflict resolution +- **validate_bundle**: Module-specific validation rules (e.g., backlog module validates feature IDs exist in ADO) + +**Alternatives considered:** +- Single `transform()` method: Too generic, loses operation semantics +- Separate read/write protocols: Overcomplicates simple unidirectional modules + +### Decision 3: AST-Based Static Analysis for Core Isolation + +**Choice:** Parse core directory ASTs and fail if any `import specfact_cli.modules.*` found + +**Rationale:** +- Compile-time enforcement: Catches violations before PR merge +- Zero runtime overhead: AST parsing in tests only +- Clear error messages: Pinpoint file and line number of violation +- CI-enforceable: Blocks PRs that add core→module coupling + +**Alternatives considered:** +- Runtime inspection: Overhead, detects after deployment +- Import hooks: Complex, fragile, runtime cost +- Manual code review:

Module Migration + +**Choice:** Update 5 existing modules incrementally, mark protocol as optional initially + +**Rationale:** +- Non-breaking: Existing modules work without immediate changes +- Incremental: Update backlog first (simplest), then sync, plan, generate, enforce +- Validation: Module registration can check protocol compliance and warn if missing + +**Alternatives considered:** +- Big-bang migration: Risky, blocks PRs across modules +- Never enforce: Defeats purpose, marketplace modules wouldn't be verifiable + +### Decision 5: ProjectBundle Schema Versioning + +**Choice:** Add `schema_version` field to ProjectBundle, document in reference docs + +**Rationale:** +- Forward compatibility: Future schema changes don't break old modules +- Marketplace safety: 3rd-party modules declare compatible schema versions +- Migration path: Old modules continue working, new modules use versioned features + +**Schema:** +```python +class ProjectBundle(BaseModel): + schema_version: str = "1.0" # NEW + manifest: BundleManifest + bundle_name: str + idea: str + # ... existing fields +``` + +**Alternatives considered:** +- No versioning: Schema changes break modules silently +- Separate
