c45aac551d feat(dedup): wire --apply path for NocoDB migration
Some checks failed
Build & Push Docker Images / lint (push) Successful in 1m12s
Build & Push Docker Images / build-and-push (push) Failing after 3m41s
Completes the migration script's apply phase, which was stubbed at
the P3 ship to defer until after the runtime surfaces (P2) and the
comms safety net were in place. Both prerequisites just landed on
main, so this unblocks the actual data import.

src/lib/dedup/migration-apply.ts (new):
  Idempotent apply driver. Walks the MigrationPlan, inserting clients,
  contacts, addresses, yacht stubs, and interests, threading every
  insert through the migration_source_links ledger so re-runs against
  the same data are safe. Per-entity transactions (not one giant
  transaction) so partial-failure resumption is just "run again."

  Per-entity behavior:
    - clients: idempotent on (source_system, source_id, target_type=client)
      across the entire dedup cluster — if any source row already maps
      to a client, reuse that record.
    - contacts: bulk insert, primary email + primary phone independent.
    - addresses: bulk insert, port_id required (schema enforces it),
      first address marked primary when multiple.
    - yachts: minimal stub when the legacy interest had a yachtName,
      currentOwnerType=client + currentOwnerId=migrated client. Linked
      via migration_source_links target_type=yacht.
    - interests: looks up berthId via mooring number, yachtId via the
      stub above. Carries Documenso ID forward when present.

  surnameToken from PlannedClient is dropped on insert (it's a dedup
  blocking-index artifact; runtime dedup re-derives from fullName).

scripts/migrate-from-nocodb.ts:
  - Removes the "not yet implemented" guard for --apply.
  - Adds EMAIL_REDIRECT_TO precondition gate: --apply errors out unless
    the env var is set, OR --unsafe-skip-redirect-check is also passed
    (production cutover only). Refers to docs/operations/outbound-comms-safety.md.
  - Re-fetches NocoDB at apply time (rather than reading a saved report
    dir) so the data is always fresh. Re-running is safe via the
    idempotency ledger.
  - Resolves target port via --port-slug (or first port if omitted).
  - Generates a UUID applyId tagged on every link, which pairs with a
    future --rollback flag.
  - Apply summary prints inserted/skipped counts per entity type plus
    the first 20 warnings.

Verification: 0 tsc errors, 926/926 vitest passing, lint clean.
The actual end-to-end run requires NOCODB_URL + NOCODB_TOKEN in .env
which aren't configured in this checkout; that's the operator's next
step.

18e5c124b0 feat(dedup): NocoDB migration script + tables (P3 dry-run)
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.
