# Phase 2 Plan 03: Admin Client Workspace (Tabs) Summary
**One-liner:** Full-featured admin client workspace with Radix Tabs covering phases/tasks, payments, documents, and comments — all mutations via inline Server Actions with server-side validation.
## What Was Built
The `/admin/clients/[id]` route delivers a complete project management workspace for the admin. Four tabs cover every concern of a client's lifecycle:
- **Fasi & Task** — Add phases and nested tasks, update phase/task status with select dropdowns
- **Pagamenti** — Edit `accepted_total` (auto-splits to 50% per payment row), update payment status (sets `paid_at` on saldato)
- **Documenti** — Add document links (label + external URL) and delete them
- **Commenti** — Read all client/admin comments chronologically; post admin replies against any task or deliverable
All mutations are Server Actions in `src/app/admin/clients/[id]/actions.ts`. The page calls `getClientFullDetail()` which assembles client + phases + tasks + deliverables + payments + documents + notes + comments in a single waterfall query sequence.
## Tasks Completed
| Task | Name | Commit | Key Files |
|------|------|--------|-----------|
| 1 | Install tabs, add getClientFullDetail, create Server Actions | 7733566 | package.json, admin-queries.ts, [id]/actions.ts, ui/tabs.tsx |
| 2 | Build detail page and all four tab components | 59a46d3 | [id]/page.tsx, PhasesTab, PaymentsTab, DocumentsTab, CommentsTab |
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 1 - Bug] Next.js 16 params must be awaited**
- **Found during:** Task 2
- **Issue:** In Next.js 16 (project uses 16.2.6), dynamic route `params` is a `Promise<{ id: string }>` not a plain object. The plan's template used `params.id` directly which would fail at runtime.
- **Fix:** Changed page signature to `params: Promise<{ id: string }>` and added `const { id } = await params;` before use.
- **Files modified:** src/app/admin/clients/[id]/page.tsx
**2. [Rule 2 - Missing critical functionality] Explicit TypeScript types on Server Action closure params**
- **Found during:** Task 2
- **Issue:** Inline closures `async (fd) => { "use server"; ... }` lacked explicit `FormData` type annotation, which could cause TypeScript inference issues.
- **Fix:** Added explicit `: FormData` type annotation on all closure parameters.
- **Files modified:** PhasesTab.tsx, PaymentsTab.tsx, DocumentsTab.tsx, CommentsTab.tsx
## Architecture Constraints Respected
- `clients.token` — Read-only in this plan. Never used as primary key.
- `quote_items` — Not queried anywhere in this plan. `accepted_total` is the only price value exposed.
- `deliverables.approved_at` — Enforced by omission: `addDeliverable` inserts `status: "pending"` with no `approved_at` field.
- Two independent auth paths — Admin workspace is under `/admin/*`, protected by middleware session from Phase 2 Plan 01.
## Security Notes (Threat Register Mitigations Applied)
- **T-02-10:** `updateTaskStatus` and `updatePaymentStatus` both validate status against an allowlist before any `db.update()` call.
- **T-02-11:** `deleteDocument` is only reachable through admin-protected routes; no client can reach it without a valid Auth.js session.
- **T-02-13:** `postAdminComment` parses the composite `"type:id"` entity value and validates `entity_type` is exactly `"task"` or `"deliverable"` before insert.
- **T-02-14:** Inline closures capture `clientId`, `phaseId`, `taskId` from the Server Component's own scope, preventing cross-client data pollution.
## Known Stubs
None — all data is live from the database via `getClientFullDetail()`.
## Threat Flags
None — no new network endpoints, auth paths, or schema changes introduced beyond what the plan's threat model covers.
