The work makes the high-risk seams visible before product fixes: lethal turn-start status command handling, dynamic runtime summary exposure, transient Pixi feedback sprite retention, oversized direct claims, and durable saved-run conversion. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ---------------------------------------------------------------------------------------------- | --------------------------------------------------- | ----- | | `.spec_system/specs/phase34-session01-characterization-test-harness/spec.md` | Session scope and acceptance criteria. | 315 | | `.spec_system/specs/phase34-session01-characterization-test-harness/tasks.md` | Completed 20-task checklist. | 76 | | `.spec_system/specs/phase34-session01-characterization-test-harness/implementation-notes.md` | Command evidence, finding map, and handoff caveats. | 691 | | `.spec_system/specs/phase34-session01-characterization-test-harness/code-review.md` | Resolved review report for all uncommitted changes. | 94 | | `.spec_system/specs/phase34-session01-characterization-test-harness/security-compliance.md` | Security and GDPR applicability review. | 80 | | `.spec_system/specs/phase34-session01-characterization-test-harness/validation.md` | PASS validation report. | 217 | | `src/extensions/ai-rogue/runtime/__tests__/renderer-lifecycle.test.ts` | Mocked feedback sprite retention characterization. | 88 | | `.spec_system/specs/phase34-session01-characterization-test-harness/IMPLEMENTATION_SUMMARY.md` | Session closeout summary. | \~80 | ### Files Modified | File | Changes | | ------------------------------------------------------------------- | ------------------------------------------------------------------------------------------- | | `src/extensions/ai-rogue/runtime/__tests__/status-expanded.test.ts` | Added lethal turn-start command-family matrix coverage. | | `src/extensions/ai-rogue/runtime/__tests__/render-model.test.ts` | Added runtime summary delta characterization. | | `src/extensions/ai-rogue/__tests__/runtime-canvas.test.tsx` | Added mounted summary exposure and durable saved-run load bridge characterization. | | `src/extensions/ai-rogue/__tests__/persistence.test.ts` | Added oversized direct claim wallet and ledger characterization. | | `src/extensions/ai-rogue/__tests__/save-schema.test.ts` | Added durable runtime snapshot validation and unsafe persisted text rejection coverage. | | `src/extensions/ai-rogue/runtime/renderer.ts` | Extracted inactive-sprite hiding into a narrow internal test seam without behavior changes. | | `.spec_system/state.json` | Marked Session 01 complete, cleared current session, and marked Phase 34 in progress. | | `.spec_system/PRD/phase_34/PRD_phase_34.md` | Updated progress to 1/8 and recorded Session 01 completion. | | `.spec_system/PRD/PRD.md` | Marked Phase 34 in progress. | | `README.md` | Synced visible version to `0.5.33`. | | `docs/CHANGELOG.md` | Added the Phase 34 Session 01 release note. | | `package.json` | Bumped version from `0.5.32` to `0.5.33`. | *** ## Technical Decisions 1. **Characterize before fixing**: Tests intentionally document current audited behavior so later remediation sessions can change behavior against a stable baseline. 2. **Keep the renderer seam narrow**: The production renderer change only extracts existing inactive-sprite hiding into a direct test helper; it does not alter mounted runtime behavior. 3. **Preserve browser-local posture**: No dependencies, remote services, hosted storage, collectors, public-demo bridge calls, or product route/view changes were added. *** ## Test Results | Metric | Value | | ------------------ | --------------------------------------------------------------------------- | | Full Vitest | 4304 / 4304 passed | | Focused AI Rogue | 273 / 273 passed | | Changed-file tests | 49 / 49 passed | | Coverage | Not collected by validation | | Quality gates | Lint, format, typecheck, script typecheck, whitespace, ASCII, and LF passed | *** ## Lessons Learned 1. Characterization tests can keep CI useful while still making known audited defects explicit for later sessions. 2. The mounted runtime bridge and render-model summary boundaries need separate coverage because source summary generation can work while DOM exposure is still absent. *** ## Future Considerations Items for future sessions: 1. Session 02 should update the mounted summary assertions when accessible dynamic runtime summary behavior is fixed. 2. Session 03 should update the lethal command-family matrix when turn-start status handling is centralized. 3. Sessions 04 and 06 should update the renderer retention, direct claim, and durable saved-run assertions when those remediation fixes land. *** ## Session Statistics * **Tasks**: 20 completed * **Files Created**: 8 * **Files Modified**: 12 updateprd and session deliverables plus pre-existing reviewed working-tree changes * **Tests Added**: 8 net new AI Rogue tests * **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/phase34-session01-characterization-test-harness/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.
