## VIES VAT Number Validator (Bulk) — Changelog

### 0.1.0 — 2026-09-06

- Real implementation landed: `src/vies_client.py` (curl-cffi + explicit
  `verify=certifi.where()` per REQ-10, retry/backoff on 429/5xx and
  body-level `MS_MAX_CONCURRENT_REQ`-style `userError` codes, never
  raises), `src/parser.py` (glued/spaced/structured input normalisation,
  `"---"` → `null` for DE/ES, check-status sentinel row), `src/main.py`
  (bounded-concurrency fan-out via `asyncio.Semaphore` + `gather`,
  per-entry fault isolation, PPE charging on every landed row).
- Live-confirmed VIES field names (`isValid`, `name`, `address`,
  `requestDate`, `userError`) against `ms/DE/vat/811907980`,
  `ms/IE/vat/6388047V`, `ms/NL/vat/810462215B01`, `ms/ES/vat/A28017895`,
  and `check-status` (2026-09-06).
- 56 unit/integration tests (models, parser, vies\_client retry/backoff,
  main fault isolation, PPE charge regression) + 1 opt-in live smoke
  test against the `input_schema.json` prefill. `ruff`/`pyright` clean.
- Added `promo.json` (GTM manifest) and wove the target keyword set
  into README copy.

### 0.0.1 — 2026-09-06

- Scaffold only — no real VIES validation yet.
- Scaffolded: `.actor/` (actor.json, input/output/dataset schemas,
  pay-per-event, Dockerfile), `src/main.py` (boots, reads input,
  validates it via `ActorInput`, charges `actor-start`, pushes one
  `skipped=true` placeholder row, and exits cleanly — no real HTTP
  call to VIES), `src/models.py` (`ActorInput`, `VatEntry`, `ResultRow`
  per ADR-0004), a smoke test, README skeleton.
