Pre-Implementation Verification Report (Task S3-001)
1. Repository Status
Current Branch: main (verified).
Working Tree: Clean (verified via git status). No modified or uncommitted files are present in the source directories.
Pending Conflicts: None.
Upstream Synchronization: Clean. Local branch is fully aligned with origin/main (verified via git diff --name-only origin/main).
2. Dependency Verification
Sprint 0, Sprint 1, and Sprint 2 Completion: Confirmed. All tasks from previous sprints are fully implemented, merged, and active.
Implementation Memories: Verified. The docs/ai/memory/ directory contains all completed task logs up to 36_AUTH003.md (the final task of Sprint 2). There are no pending or draft implementation memories.
3. Frozen Kernel Verification
Status: Clean (all files are 100% untouched and byte-identical to the baseline).
The following directories/files were audited and confirmed unchanged:
app/core/* (including app/core/Session.php, app/core/Request.php, app/core/Csrf.php, etc.)
app/core/Router.php
app/core/BaseController.php
app/core/MiddlewarePipeline.php
4. Database Verification
Database Connection: Active (MariaDB server started locally on port 3306).
Database Target: inveetaire (exists).
Prerequisites Status: FAILED (Tables Missing).
Audit Results: The database is currently empty and contains 0 tables. The required schema tables from PDD v1.0 do not exist:
workspaces (Missing ❌)
users (Missing ❌)
invitations (Missing ❌)
invitation_sections (Missing ❌)
retention_policies (Missing ❌)
message_templates (Missing ❌)
printer_configurations (Missing ❌)
audit_logs (Missing ❌)
5. Existing Workspace Components
Status: Verified clean. The codebase contains no pre-existing workspace components:
WorkspaceMiddleware (Does not exist ❌)
Workspace module folder under app/modules/ (Does not exist ❌)
WorkspaceService (Does not exist ❌)
WorkspaceController (Does not exist ❌)
WorkspaceModel (Does not exist ❌)
6. Implementation Order Verification
Sequence Alignment: Confirmed. The execution order defined in 

SPRINT3_PLANNING.md
 and 

SPRINT3_EXECUTION_GUIDE.md
 is perfectly aligned with the target roadmap:
Security Hardening (CSP + Rate Limiting + Token Cleanup pre-checklist)
WorkspaceMiddleware (Tenant isolation guard)
WS-001 (Workspace Provisioning)
WS-002 (Setup Checklist widgets)
WS-003 (Phase Transitions lifecycle)
7. Documentation Conflicts
Status: None. All governance, architecture, and planning documents are in 100% alignment.
Recommendation
NOT READY

Blocking Issue:

The database inveetaire is completely empty. The prerequisite database tables (workspaces, users, invitations, invitation_sections, retention_policies, message_templates, printer_configurations, and audit_logs) do not exist.
Per the strict guidelines of S3-001, implementation cannot begin, and migrations cannot be created autonomously by the AI agent.
I have halted execution at this checkpoint. Please provide instructions on how to seed/migrate the schema before we proceed.
