Phase 8 Implementation Status

> Historical implementation snapshot, dated 2026-10-02 (notice added 2026-11-02). This document is historical implementation evidence. It is not a canonical architecture owner, is outside the governed documentation structure and authority map (see PRR-048 in the readiness register), and is not the current implementation status. Its "COMPLETE" and "Ready for staging validation" statements describe 2 October 2026 only and are not current evidence that any feature is operational, validated or deployed. "Principal" in this document is superseded terminology for User (the platform identity); persisted identifiers such as principal_id remain unchanged until a separately authorised migration (legacy identifiers). Current implementation evidence is in implementation status; unresolved readiness items are in the readiness register.

Date: 2026-10-02 Status: ✅ COMPLETE - Ready for staging validation

Phase 8: Dashboard UI Enhancements

Scope: User presentation preferences (reorder, resize) with database persistence and page-load restoration.

Deliverables:

Architecture Compliance

Universal Object Model Maintained

Governance Boundaries Respected

Database Authority Maintained

Backward Compatibility

Implementation Details

1. API Endpoints (3 total)

Endpoint: POST /presentations/preference/order

Endpoint: POST /presentations/preference/span

Endpoint: POST /presentations/preference/height (NEW)

2. Type Schema Extension

Type: UserPresentationPreferenceTypeRevision Change: Added optional field to constituent_preferences[] items schema

{
  "constituent_preferences": {
    "type": "array",
    "items": {
      "type": "object",
      "properties": {
        "type_id": { "type": "string" },
        "preferred_order": { "type": "integer", "minimum": 0 },
        "preferred_span": { "type": "integer", "enum": [2, 3, 4, 6] },
        "preferred_height": { "type": "integer", "minimum": 12 }
      },
      "required": ["type_id"],
      "additionalProperties": false
    }
  }
}

Backward Compatibility:

3. Frontend Implementation

File: resources/js/dashboard-drag-drop.js (source) / target/js/dashboard-drag-drop.js (deployed)

Features: 1. Drag-and-drop with live position guides

2. Resize handle (bottom-right corner)

3. Persistence

4. Backend Implementation

File: app/Runtime/Presentation/TargetHtmlBoundary.php

Changes:

Merge Logic: 1. Load existing USER_PRESENTATION_PREFERENCE_TYPE object (if exists) 2. Parse existing constituent_preferences array 3. Update only the field being changed 4. Preserve all other fields 5. Create new version of object with updated value 6. Return success response

5. Preference Loading

File: app/Runtime/Presentation/PresentationPreferenceService.php

Method: enhanceConstituentsWithPreferences()

Default Fallbacks:

6. Layout Calculation

File: app/Runtime/Presentation/PersistedCapabilityProjector.php

Method: applyLayout() (updated)

Bug Fix:

7. Template Rendering

File: resources/views/target/capability.php

Changes: 

<!-- Before -->
style="grid-column: span <?= (int) ($constituent['effective_span'] ?? 2) ?>; min-height: 12rem; position: relative;"

<!-- After -->
style="grid-column: span <?= (int) ($constituent['effective_span'] ?? 2) ?>; min-height: <?= (int) ($constituent['effective_height'] ?? 12) ?>rem; position: relative;"

Data Attributes: 

data-preferred-span="<?= (int) ($constituent['preferred_span'] ?? 2) ?>"
data-preferred-height="<?= (int) ($constituent['preferred_height'] ?? 12) ?>"

Testing & Validation

Code Validation (Automated)

Manual Validation Required

Database Validation (Staging Only)

-- Check preferences stored for a user/business/capability
SELECT id, value FROM objects 
WHERE type_id = '8c4f6b8c-3d2e-4f10-8a11-223344556692'
AND business_id = '[business_id]'
LIMIT 1;

-- Should show JSON with constituent_preferences array
-- containing preferred_order, preferred_span, preferred_height

Deployment Readiness

Prerequisites Met

Deployment Steps

1. Deploy code to staging 2. Run manual validation suite (Phase-8-Validation-Checklist.md) 3. Verify database state queries return valid preferences 4. Verify browser console: no errors, expected logs present 5. Test end-to-end: drag → persist → reload → verify 6. Approve for production deployment

Known Limitations

Git Commits

| Commit | Message | Files Changed | |--------|---------|----------------| | 00e1d3d | Phase 8: Implement resize handle with ghost preview and bidirectional sizing | 4 | | 682dd4c | Phase 8: Implement height restoration on page load | 3 | | 23ac1c7 | Phase 8: Implement space-making drag-and-drop with live position guides | 3 | | c30e1e8 | Phase 8: Add completion summary and validation checklist | 2 |

Total: 4 commits, 8 files modified, ~550 lines of code

Architectural Decisions

Why Database Objects (Not Application State)

Why Optional `preferred_height` Field

Why Three Separate Endpoints (Not One)

Why Store Preferences Per-Constituent Per-Capability

Next Steps

Immediate (Required for production): 1. ✅ Commit to main (DONE) 2. ⏳ Manual validation (see Checklist) 3. ⏳ Staging deployment 4. ⏳ Production deployment

Future (Out of scope for Phase 8):
