The registry validator now checks runtime catalog references and finale ownership with sanitized issue output, while save-schema persisted ID arrays are exported for parity tests without importing runtime catalogs into the parser. *** ## Deliverables ### Files Created | File | Purpose | Lines | | -------------------------------------------------------------- | ------------------------------------------------------------ | ----- | | `src/extensions/ai-rogue/__tests__/save-schema-parity.test.ts` | Runtime catalog to save-schema persisted ID parity coverage. | 86 | ### Files Modified | File | Changes | | -------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | | `src/extensions/ai-rogue/save-schema.ts` | Exported parser-owned persisted and compatibility ID arrays for protocols, terminals, enemies, and sector themes while preserving schema version 1. | | `src/extensions/ai-rogue/runtime/content/types.ts` | Added validation issue codes for objective, boss, and finale ownership failures. | | `src/extensions/ai-rogue/runtime/content/validate.ts` | Added explicit validation for level references, objectives, music, ambience, pickups, boss references, and finale ownership with sanitized issue metadata. | | `src/extensions/ai-rogue/runtime/content/__tests__/levels.test.ts` | Added malformed-reference coverage for every session-named reference class and authoring-path assertions through level specs. | | `src/extensions/ai-rogue/runtime/__tests__/runtime-boundary.test.ts` | Added import-boundary coverage for shared registry validation and save-schema parser paths. | | `.spec_system/state.json` | Marked Session 03 validated and completed in workflow state. | | `.spec_system/PRD/phase_39/PRD_phase_39.md` | Marked Session 03 complete and advanced phase progress. | | `package.json` | Incremented patch version from 0.5.91 to 0.5.92. | *** ## Technical Decisions 1. **Parser-owned persisted ID arrays**: Save-schema ID literals stay in `save-schema.ts`, and tests compare them to runtime catalogs. This keeps browser-local parsers independent from runtime content modules. 2. **Explicit compatibility arrays**: Save-only retired IDs are allowed only through named compatibility arrays, so accidental runtime/save drift fails tests. 3. **Sanitized validation issues**: Registry validation reports stable codes, paths, depths, and level IDs without echoing unsafe source values. *** ## Test Results | Metric | Value | | ------------- | ------------ | | Focused tests | 39 passed | | Full tests | 4638 passed | | Typecheck | PASS | | Lint | PASS | | Coverage | Not reported | *** ## Lessons Learned 1. Save-schema parity belongs in tests instead of runtime parser imports. 2. Registry validation needs explicit ownership checks for finale semantics, not just catalog membership checks. 3. Import-boundary tests are the right guardrail for keeping parser and content validation free of product-surface modules. *** ## Future Considerations Items for future sessions: 1. Use these gates while adding the existing-media fourth floor in Session 04. 2. Add non-empty compatibility arrays only when a runtime ID is deliberately retired but must remain loadable. 3. Keep any future boss or finale expansion data-driven before adding new renderer or combat branches. *** ## Session Statistics * **Tasks**: 16 completed * **Files Created**: 1 * **Files Modified**: 8 * **Tests Added**: 1 * **Blockers**: 0 resolved --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase39-session03-registry-validation-and-save-parity/implementation_summary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
