Lands the one-shot migration pipeline from the legacy NocoDB Interests
base into the new client/interest schema. Dry-run mode is fully
operational: pulls the live snapshot, runs the dedup library, and
writes a CSV + Markdown report under .migration/<timestamp>/. The
--apply phase is stubbed for a follow-up PR per the design's P3
implementation sequence.
Schema additions
================
- `client_merge_candidates` — pairs flagged by the background scoring
job for the /admin/duplicates review queue. Status enum: pending /
dismissed / merged. Unique-(portId, clientAId, clientBId) so the
same pair can't surface twice. Empty until P2 lands the cron.
- `migration_source_links` — idempotency ledger. Maps source-system
rows (NocoDB Interest #624 → new client UUID) so re-running --apply
against the same dry-run report skips already-imported entities.
Both tables ship with the migration `0020_unusual_azazel.sql` —
already applied to the local dev DB during this commit's preparation.
Library
=======
src/lib/dedup/nocodb-source.ts
Read-only adapter for the legacy NocoDB v2 API. xc-token auth,
auto-paginates until isLastPage, captures the table IDs from the
2026-05-03 audit. `fetchSnapshot()` pulls every relevant table in
parallel into one in-memory object the transform layer consumes.
src/lib/dedup/migration-transform.ts
Pure function: NocoDB snapshot in, MigrationPlan out. Per row:
- normalizes name / email / phone / country via the dedup library
- parses the legacy DD-MM-YYYY / DD/MM/YYYY / ISO date formats
- maps the 8-stage `Sales Process Level` enum to the new 9-stage
pipelineStage
- filters yacht-name placeholders ('TBC', 'Na', etc.)
- merges Internal Notes + Extra Comments + Berth Size Desired into
a single notes blob
Then runs `findClientMatches` pairwise (with blocking) and
union-finds clusters of rows whose score crosses the auto-link
threshold (90). Lower-scoring pairs (50–89) become 'needs review'.
Each cluster's "lead" row is picked by completeness score with
recency tie-break.
src/lib/dedup/migration-report.ts
Writes three artifacts to .migration/<timestamp>/:
- report.csv — one row per planned op, RFC-4180 escaped
- summary.md — human-skimmable overview
- plan.json — full structured plan for the --apply phase
CSV cells with comma / quote / newline are quoted; internal quotes
are doubled. No external CSV dep.
src/lib/dedup/phone-parse.ts
Script-safe wrapper around libphonenumber-js's `core` entry that
loads `metadata.min.json` directly. The default `index.cjs.js`
bundled by libphonenumber hits a metadata-shape interop bug under
Node 25 + tsx (`{ default }` wrapping); core+JSON sidesteps it.
The dedup `normalizePhone` and `find-matches` both use this wrapper
now so the same code path runs in vitest, Next.js, and the migration
CLI without surprises.
src/lib/dedup/normalize.ts
Tightened country resolution: added Caribbean short-form aliases
('antigua' → AG, 'st kitts' → KN, etc.) and a city map covering the
US locations seen in the NocoDB dump (Boston, Tampa, Fort
Lauderdale, Port Jefferson, Nantucket). Also relaxed phone parsing
to drop the `isValid()` strict check — the libphonenumber min build
rejects many real NANP-territory numbers, and dedup only needs a
canonical E.164 to compare.
CLI
===
scripts/migrate-from-nocodb.ts
pnpm tsx scripts/migrate-from-nocodb.ts --dry-run
→ Pulls the live NocoDB base (NOCODB_URL + NOCODB_TOKEN env vars),
runs the transform, writes report. No DB writes.
pnpm tsx scripts/migrate-from-nocodb.ts --apply --report .migration/<dir>/
→ Stubbed; exits with `not yet implemented` and a pointer to the
design doc. Apply phase ships in a follow-up.
Tests
=====
tests/unit/dedup/migration-transform.test.ts (7 cases)
Fixture-based regression. A frozen 12-row NocoDB snapshot covers
every duplicate pattern in the design (§1.2). The test asserts:
- 12 input rows → 7 unique clients (cluster math is right)
- Patterns A / B / C / E auto-link
- Pattern F (Etiennette Clamouze) does NOT auto-link
- Every interest preserved as its own row even when clients merge
- 8-stage → 9-stage enum mapping is correct per spec
- Multi-yacht merge (Constanzo CALYPSO + Costanzo GEMINI under one
client) — the design's signature win
- Output is deterministic (run twice, identical)
Validation against real data
============================
Ran `pnpm tsx scripts/migrate-from-nocodb.ts --dry-run` against the
live NocoDB. Result on 252 Interests rows:
- 237 clients (15 merged into 13 clusters)
- 252 interests (one per source row)
- 406 contacts, 52 addresses
- 13 auto-linked clusters (every confirmed cluster from §1.2 audit)
- 3 pairs flagged for review (Camazou, Zasso, one new)
- 1 phone placeholder flagged
Total dedup test count: 57 (50 from P1 + 7 fixture tests).
Lint: clean. Tsc: clean for new files.
