+# Task H - PDF Generation and Approved Document Persistence
+
+## Files Added

+- `src/app/api/crm/quotations/[id]/pdf-preview/route.ts`
+- `src/app/api/crm/quotations/[id]/pdf-download/route.ts`
+- `src/app/api/crm/quotations/[id]/approved-pdf/route.ts`
+- `drizzle/0007_luxuriant_malice.sql`
+

+- `src/features/crm/quotations/schemas/quotation.schema.ts`
+- `docs/implementation/technical-debt.md`
+
+## PDF Generator Added
+
+- Added production server-side `pdfme` generation in `src/features/foundation/pdf-generator/server/service.ts`.
+- Installed:
+  - `@pdfme/common`
+  - `@pdfme/generator`
+  - `@pdfme/schemas`
+- Implemented:
+  - `generatePdfFromTemplate()`
+  - `generateQuotationPdf()`
+  - `generateQuotationPreviewPdf()`
+  - `generateApprovedQuotationPdf()`
+  - `getStoredApprovedQuotationPdf()`
+
+## API Routes Added
+
+- `GET /api/crm/quotations/[id]/pdf-preview`
+- `GET /api/crm/quotations/[id]/pdf-download`
+- `GET /api/crm/quotations/[id]/approved-pdf`
+- `POST /api/crm/quotations/[id]/approved-pdf`
+
+Behavior:
+
+- preview returns inline PDF from current quotation state
+- download returns attachment PDF from current quotation state
+- approved-pdf POST generates, persists, audits, and returns the approved PDF
+- approved-pdf GET streams the already stored approved artifact
+
+## UI Actions Added
+
+Quotation detail now supports:
+
+- `Preview PDF`
+- `Download PDF`
+- `Generate Approved PDF`
+- `View Approved PDF`
+
+The detail page also now displays:
+
+- `Approved At`
+- `Approved Template Version`
+
+## Approved Snapshot Persistence
+
+Added quotation persistence fields:
+
+- `approvedAt`
+- `approvedPdfUrl`
+- `approvedSnapshot`
+- `approvedTemplateVersionId`
+
+Approved snapshot now stores:
+
+- quotation id
+- approved timestamp
+- normalized document data
+- template version id
+- mapped template input
+- generated timestamp
+- generated by user id
+
+## Attachment Metadata Integration
+
+After generating an approved PDF:
+
+- a local file is written under `public/generated/quotations/<organizationId>/`
+- quotation attachment metadata is created or updated with:
+  - `fileName`
+  - `originalFileName`
+  - `filePath`
+  - `fileSize`
+  - `fileType = application/pdf`
+  - `description = Approved quotation PDF`
+  - `uploadedBy`
+  - `uploadedAt`
+
+## Permission Added
+
+- `crm.quotation.pdf.preview`
+- `crm.quotation.pdf.download`
+- `crm.quotation.pdf.generate_approved`
+
+## Audit Integration
+
+Required audit was added for approved PDF generation with:
+
+- `entityType = crm_quotation_pdf_generate_approved`
+- `action = generate_approved`
+
+Preview and download remain unaudited by design.
+
+## Remaining Risks
+
+- Current `pdfme` generation uses a font fallback normalization step because the provided templates reference `cordia/cordiaBold`, while direct TTC-based rendering did not behave reliably with table layout generation.
+- Approved PDF storage uses local filesystem placeholder output under `public/generated/...`, not external object storage.
+- The environment used during implementation had no quotation rows available in the database, so full quotation-specific end-to-end smoke testing through a live record could not be completed here.
+
+## Task I Readiness
+
+Task H leaves the repo ready for:
+
+- auto-generate approved PDF after final approval
+- object-storage abstraction
+- signed download / retention policy
+- immutable approved artifact lifecycle rules
+- richer template version publish controls

 - storage abstraction
 - immutable approved artifact URL on quotation

+## After Task H
+
+### Font Render Parity
+`pdfme` generation currently falls back from `cordia/cordiaBold` to standard fonts when TTC-backed runtime rendering is not reliable.
+
+Future:
+- package or vendor the exact Cordia font assets in a generator-friendly format
+- remove fallback normalization
+- verify Thai text metrics against the original designer output
+
+### Local PDF Storage
+Approved PDFs currently persist to local `public/generated/...` paths.
+
+Future:
+- object storage provider abstraction
+- signed/private delivery strategy
+- retention and regeneration policy
+
+### Post-Approval Automation
+Approved PDF generation is still manual by design.
+
+Future:
+- optional auto-generate hook after final approval
+- retry-safe job queue for PDF generation
