Phase 02 Plan 04: Client Interactions — Approvals + Comments Summary

One-liner: Client-facing approval and comment API routes with token validation, ownership verification, approved_at immutability enforcement, and inline ApproveButton/CommentForm/CommentList wired into the Phase 1 dashboard via PhaseTimeline.

What Was Built

API Routes

POST /api/client/approve (src/app/api/client/approve/route.ts):

• Reads { token, deliverableId } from request body
• Validates token → finds clientId via clients table
• Verifies deliverable ownership: deliverables → tasks → phases.client_id = clientId (innerJoin chain prevents cross-client approval — T-02-16)
• Checks approved_at !== null — if already set, returns 200 no-op (T-02-17 immutability)
• Sets status = 'approved' and approved_at = new Date() atomically
• Returns 404 on invalid token or missing deliverable; 500 on unexpected error

POST /api/client/comment (src/app/api/client/comment/route.ts):

• Reads { token, entity_type, entity_id, body } from request body
• Zod schema validates: entity_type enum, body min 1 / max 2000 chars (T-02-20 DoS mitigation)
• Validates token → finds clientId
• For tasks: verifies task belongs to a phase owned by clientId
• For deliverables: verifies deliverable belongs to a task in a phase owned by clientId (T-02-18)
• Inserts comment with author: 'client'
• Returns 201 on success; 400 on validation failure; 404 on invalid token/entity

Client Components

ApproveButton (src/components/client/ApproveButton.tsx):

• 'use client' directive
• If approvedAt !== null: renders immutable green badge "Approvato il [localeDateString it-IT]"
• Otherwise: renders "Approva" button; on click POSTs to /api/client/approve, calls router.refresh() on success
• Loading state disables button; error message shown below on failure

CommentForm (src/components/client/CommentForm.tsx):

• 'use client' directive
• Textarea + submit button; disabled when body is empty or loading
• POSTs to /api/client/comment with { token, entity_type, entity_id, body }
• On success: clears textarea, calls router.refresh() to reload comments from server

CommentList (src/components/client/CommentList.tsx):

• Pure presentational Server Component (no 'use client')
• Renders nothing when empty
• Admin comments: right-aligned, dark bubble, labelled "iamcavalli"
• Client comments: left-aligned, gray bubble, labelled "Tu"

Dashboard Wiring

page.tsx — extended to:

• Collect all task IDs and deliverable IDs from the ClientView
• Run single db.select().from(comments).where(inArray(comments.entity_id, allEntityIds)) query
• Pass token and allComments to <ClientDashboard>
• Changed revalidate from 60 (ISR) to 0 (always fresh)

client-dashboard.tsx — updated ClientDashboardProps to include token: string and comments: Comment[]; passes both to <PhaseTimeline>

phase-timeline.tsx — extended PhaseTimelineProps with token and comments; added commentsFor() helper; renders within each task: ApproveButton on each deliverable, CommentList + CommentForm below each deliverable and below each task

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Missing @radix-ui/react-tabs dependency caused build failure

• Found during: Task 1 build verification
• Issue: tabs.tsx component (from Plan 02-03) imported @radix-ui/react-tabs which was listed in package.json but not installed in the worktree's node_modules
• Fix: Ran npm install in the main repo directory to install all declared dependencies
• Files modified: None (package install only)
• Commit: Resolved before Task 1 commit; no separate commit needed

2. [Rule 3 - Blocking] Missing .env.local in worktree caused build page-data collection error

• Found during: Task 1 build verification (second attempt)
• Issue: DATABASE_URL env var is required error during page data collection; .env.local exists in main repo but not copied to worktree
• Fix: Copied .env.local from main repo to worktree root (file is gitignored)
• Files modified: .env.local (worktree only, not committed)
• Commit: Not committed (gitignored)

3. [Rule 2 - Missing prop type] ClientDashboard and PhaseTimeline needed prop signature updates

• Found during: Task 2 — IDE diagnostic after updating page.tsx
• Issue: ClientDashboard and PhaseTimeline had no token or comments props in their interfaces — TypeScript error TS2322
• Fix: Updated ClientDashboardProps and PhaseTimelineProps to include token: string and comments: Comment[]; updated function signatures and render logic accordingly
• Files modified: src/components/client-dashboard.tsx, src/components/phase-timeline.tsx
• Commit: dc512ec (included in Task 2 commit)

Known Stubs

None — all components are fully wired to live API routes and server-fetched data.

Threat Surface Scan

All threat mitigations from the plan's <threat_model> are implemented:

Threat ID	Status	Implementation
T-02-15	Mitigated	Token validated via DB lookup before any mutation in both routes
T-02-16	Mitigated	innerJoin chain (deliverable → task → phase → client_id) prevents cross-client approval
T-02-17	Mitigated	approved_at !== null check before UPDATE; no-op 200 if already approved
T-02-18	Mitigated	Entity ownership verified via phase → client_id chain before comment insert
T-02-19	Accepted	Comments scoped to entity_ids from validated client's view; server-side filtered
T-02-20	Mitigated	Zod schema enforces max(2000) on comment body; returns 400 if exceeded

No new threat surface introduced beyond what is documented in the plan.
