The primary Orchestration open action now opens the shared bottom-rail focused surface with the existing Command Center workbench, including Campaigns, File/Git, Attention, Executors, Federation, and Metrics. The retained details portal is now a secondary state summary, and tests prove same-instance expansion, state preservation, focus restoration, and no duplicate hydration. *** ## Deliverables ### Files Created | File | Purpose | Lines | | ------------------------------------------------------------------------------------------------------- | ------------------------------------ | ----- | | `.spec_system/specs/phase21-session03-orchestration-command-center-expansion/spec.md` | Session implementation specification | \~238 | | `.spec_system/specs/phase21-session03-orchestration-command-center-expansion/tasks.md` | Completed task checklist | \~78 | | `.spec_system/specs/phase21-session03-orchestration-command-center-expansion/implementation-notes.md` | Task evidence and implementation log | \~650 | | `.spec_system/specs/phase21-session03-orchestration-command-center-expansion/code-review.md` | Review and repair report | \~70 | | `.spec_system/specs/phase21-session03-orchestration-command-center-expansion/security-compliance.md` | Security and GDPR review | \~76 | | `.spec_system/specs/phase21-session03-orchestration-command-center-expansion/validation.md` | Validation report | \~198 | | `.spec_system/specs/phase21-session03-orchestration-command-center-expansion/IMPLEMENTATION_SUMMARY.md` | Session closeout summary | \~70 | ### Files Modified | File | Changes | | -------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | | `apps/web/src/components/BottomRailExpansionHost.tsx` | Restores focus for surfaces opened through shared store state and clears stale opener references. | | `apps/web/src/components/orchestration/OrchestrationCurrentState.tsx` | Updates state-summary wording for the retained secondary inspector. | | `apps/web/src/components/orchestration/OrchestrationHeader.tsx` | Splits primary Command Center open action from secondary state-summary action and updates ARIA/copy. | | `apps/web/src/components/orchestration/OrchestrationShell.tsx` | Routes the primary Orchestration action to `expandedBottomRailSurfaceId = "orchestration"` while preserving local shell state. | | `apps/web/tests/OrchestrationPanel.test.tsx` | Adds expanded Command Center, tab reachability, state preservation, focus restoration, and no duplicate hydration coverage. | | `.spec_system/state.json` | Marks the session complete and clears `current_session`. | | `.spec_system/PRD/phase_21/PRD_phase_21.md` | Marks Session 03 complete and updates Phase 21 progress to 3/7. | | `.spec_system/PRD/phase_21/session_03_orchestration_command_center_expansion.md` | Marks prerequisites and success criteria complete. | | `.spec_system/PRD/PRD.md` | Marks Phase 21 in progress in the master phase summary. | | `apps/web/package.json` | Bumps package version from 0.1.50 to 0.1.51. | | `package-lock.json` | Syncs the apps/web package version to 0.1.51. | *** ## Technical Decisions 1. **Same-instance expansion**: Used the existing `BottomRailExpansionHost` path so focused Orchestration promotes the mounted panel instead of rendering a second Orchestration tree. 2. **Primary and secondary actions**: Made `Open Command Center` the primary route and retained the previous details portal as `State summary`. 3. **Store-open focus repair**: Updated the shared host so surfaces opened by writing shared store state still restore focus to the opener on close. *** ## Test Results | Metric | Value | | ------------- | ---------------------------------- | | Focused Tests | 51 passed / 0 failed | | Full Suite | 3143 passed / 1 skipped / 0 failed | | Coverage | Not reported | *** ## Lessons Learned 1. Shared store-driven surface opens still need the host focus contract, not only host-owned button opens. 2. The product route and the state-summary inspector should remain separate so the primary Orchestration path answers where Campaigns is operated. *** ## Future Considerations Items for future sessions: 1. Session 04 should handle shortcut routing and nested overlay/Escape precedence. 2. Session 05 should apply the same focused-surface contract to Quest Board and War Room. *** ## Session Statistics * **Tasks**: 22 completed * **Files Created**: 7 * **Files Modified**: 11 * **Tests Added**: 5 behavior groups * **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://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase21-session03-orchestration-command-center-expansion/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.
