tags: [drizzle, postgres, neon, schema, quote_items]

# Dependency graph
requires:
  - phase: 02-admin-area-interactive-features
    provides: quote_items table with service_catalog FK already in place
provides:
  - quote_items.service_id nullable (allows free-form items without catalog reference)
  - quote_items.custom_label text column (stores free-form item label)
  - Live Neon DB schema synced — Wave 2 plans can safely insert rows with service_id = null
affects:
  - 03-02 (service catalog CRUD — reads quote_items with custom_label)
  - 03-03 (quote builder — inserts rows with service_id null and custom_label)
  - 03-04 (quote display — renders custom_label for free-form items)

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "Drizzle nullable FK: omit .notNull() from FK column to allow null — relation definition unchanged"

key-files:
  created: []
  modified:
    - src/db/schema.ts

key-decisions:
  - "service_id remains as FK reference (onDelete: restrict) but is now nullable — Drizzle handles nullable FK relations correctly, no changes to quoteItemsRelations needed"
  - "custom_label is plain text (no notNull) — free-form items set it, catalog-linked items leave it null"

patterns-established:
  - "Nullable FK pattern: .references(...) without .notNull() — Drizzle infers string | null type automatically"

# Phase 03 Plan 01: Schema — quote_items Nullable service_id + custom_label Summary

**Added `custom_label text` column and made `service_id` nullable in `quote_items` via Drizzle schema edit + Neon DDL push — unblocking Wave 2 free-form quote items**

## Performance

- **Duration:** ~3 min
- **Started:** 2026-05-17T09:35:00Z
- **Completed:** 2026-05-17T09:37:38Z
- **Tasks:** 2
- **Files modified:** 1 (src/db/schema.ts)

## Accomplishments

- Removed `.notNull()` from `quote_items.service_id` — field is now `string | null` in TypeScript
- Added `custom_label: text("custom_label")` column to `quote_items` table definition
- Executed `drizzle-kit push` against live Neon DB — changes applied, second run confirmed "No changes detected"

## Task Commits

Each task was committed atomically:

1. **Task 1: Update quote_items schema — make service_id nullable and add custom_label** - `9ddb699` (feat)
2. **Task 2: Push schema changes to Neon database** — no file commit (DB-only DDL operation; verified via `drizzle-kit push` output)

**Plan metadata:** committed with SUMMARY.md

## Files Created/Modified

- `src/db/schema.ts` — Removed `.notNull()` from `service_id`, added `custom_label: text("custom_label")` after `subtotal` in quote_items table

## Decisions Made

- `quoteItemsRelations` block was left unchanged — Drizzle handles nullable FK relations without requiring changes to the relation definition
- No migration file generated (using `drizzle-kit push` mode, not `drizzle-kit generate` + migrate)

## Deviations from Plan

### Auto-fixed Issues

**1. [Rule 3 - Blocking] Edited worktree file instead of main repo file**
- **Found during:** Task 1
- **Issue:** Initial edit went to `/Users/simonecavalli/IAMCAVALLI/src/db/schema.ts` (main repo) instead of the worktree copy at `src/db/schema.ts` relative to worktree root
- **Fix:** Applied same edits to the correct worktree file; reverted accidental main-repo edit via `git checkout -- src/db/schema.ts` in the main repo
- **Files modified:** worktree `src/db/schema.ts` (correct), main repo reverted to HEAD
- **Verification:** `git status` in worktree showed only `src/db/schema.ts` modified; main repo schema unchanged
- **Committed in:** `9ddb699` (Task 1 commit)

---

**Total deviations:** 1 auto-fixed (1 path confusion / blocking)
**Impact on plan:** Fix was immediate and required. No scope creep. End result is identical to plan spec.

## Issues Encountered

- Worktree path confusion: the `read_first` directive in the plan pointed to `/Users/simonecavalli/IAMCAVALLI/src/db/schema.ts` (absolute main-repo path), and the initial edit went there instead of the worktree copy. Caught immediately by checking `git status --short` in the worktree before committing.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Wave 2 plans (03-02, 03-03, 03-04) can now safely reference `quote_items.custom_label` and insert rows with `service_id = null`
- No blockers or concerns

## Self-Check: PASSED

- FOUND: `src/db/schema.ts` — correct worktree file with both changes
- FOUND: `03-01-SUMMARY.md`
- FOUND: commit `9ddb699` (Task 1)
- FOUND: `custom_label: text("custom_label")` in schema
- OK: `service_id` has no `.notNull()` (grep -A2 shows `.references(...)` then `quantity.notNull()` — the notNull is on quantity, not service_id — confirmed correct)
