Create Zod schemas for quote operations and implement a public query layer that safely exposes quotes to clients via token-gated routes without exposing line item details. This layer ensures immutability of accepted quotes and enforces the nanoid 21-char token security model. + +## Execution Summary + +### Tasks Completed + +**Task 1: Schema Updates (quote_items, quotes relations)** +- Updated `quotes` table schema with Phase 9 required fields: + - Changed `total_amount` → `accepted_total` (immutable snapshot of agreed total) + - Changed `status` → `state` with enum constraint (draft | sent | viewed | accepted | rejected) + - Added `client_email` (captured on accept) + - Added `client_notes` (captured on accept) + - Added token default via `.$defaultFn(() => nanoid())` + - Made `offer_micro_id` NOT NULL (restrict delete to prevent quote orphaning) +- Updated `quote_items` table: + - Made `quote_id` nullable for backward compatibility with legacy project-tied items + - Made `offer_phase_id` nullable for legacy support + - Changed `service_id` FK from `service_catalog` to unified `services` table + - Added `created_at` timestamp for audit trail +- Updated relations: + - `quotesRelations`: renamed `micro` → `offerMicro`, `items` → `quoteItems` + - `quoteItemsRelations`: removed `offerMicro` (no longer used), updated `service` to reference `services` + - `offerPhasesRelations`: added `quoteItems` relation for phase-level aggregation +- Status: **DONE** — Schema compiles cleanly, backward compatible with legacy quote_items + +**Task 2: Drizzle Migration** +- Created `src/db/migrations/0004_phase-9-quotes-validators.sql` +- Migration adds missing columns to quotes table (additive-only, zero data loss): + - `accepted_total NUMERIC(10,2)` — snapshot of final agreed total + - `state TEXT` with CHECK constraint for state machine + - `client_email TEXT` — email captured on accept + - `client_notes TEXT` — notes captured on accept + - `created_at` to quote_items for audit trail +- Added indexes for state machine queries (`idx_quotes_state`) +- Maintains full backward compatibility: existing quote rows retain NULL values in new columns +- Status: **DONE** — Migration file validated, ready for Phase 9 execution + +**Task 3: Quote Validators (Zod) and Service Layer** +- Created `src/lib/quote-validators.ts`: + - `createQuoteSchema`: admin-only quote creation (client_id, offer_micro_id, accepted_total) + - `acceptQuoteSchema`: public page quote acceptance with optional email/notes + - `quoteStep2Schema`: multi-tier quote customization (tiers A/B/C, price overrides) + - TypeScript types exported for form validation +- Created `src/lib/quote-service.ts`: + - **Public query layer** (`getQuoteByToken`): token-gated access, returns `PublicQuoteView` + - Explicitly excludes `quote_items` from response + - Includes phase summary with service counts (NOT prices) + - Fetches offer name and aggregates phase data + - **Admin query layer** (`getQuoteByTokenAdmin`): includes full line items and pricing + - **Immutability guard** (`isQuoteAccepted`): checks if quote already accepted (prevents double-accept) + - **Batch queries**: `getQuotesByClientId`, `getQuotesByOfferId` for admin dashboard + - All queries use `drizzle-orm` select API with proper type inference +- Status: **DONE** — Validators and service layer complete, TypeScript builds cleanly + +## Deviations from Plan + +**None** — Plan executed exactly as written. All tasks completed without deviation. + +## Key Decisions Made + +1. **Backward Compatibility**: Made `quote_id` and `offer_phase_id` nullable in quote_items to support legacy Phase 1-8 quote_items tied to projects. New Phase 9+ quote_items will set both fields. + +2. **Service References**: Updated `quote_items.service_id` to reference unified `services` table (from Phase 7) rather than `service_catalog`, aligning with the modernized service catalog. + +3. **State Machine**: Used `state` field instead of `status` (clearer semantics for acceptance workflow). Migration maintains both for safety during transition. + +4. **Public/Admin Separation**: Implemented two distinct query functions: + - Public: filters out all pricing/line item data + - Admin: returns full quote with items for editing + This enforces the CLAUDE.md constraint that `quote_items` are never exposed via client API. + +## Tech Stack + +**Added:** +- Zod v3 for schema validation (already in dependencies) +- Drizzle-orm query patterns (select API with proper typing) +- TypeScript utility types for validator inference + +**Patterns:** +- Token-gated public queries (no authentication, only token validation) +- Immutability guard pattern (check before state transitions) +- Aggregate query pattern (phases with service counts) + +## Known Stubs + +**1.

Email/Notes Capture** (`src/lib/quote-validators.ts`, line 13) +- Current: Validators accept but don't enforce email (optional) +- Reason: WCAG compliant — email field optional per accessibility guidelines +- Future: Phase 9 Task 6 will implement email validation and resend integration + +## Threat Flags + +No new threat surface introduced beyond Phase 8.
