## [0.1.0] - Unreleased

### Added

- Initial public release, extracted from Mobiletic's production Swiss-nLPD chatbot.
- `Anonymizer` — pre-filter → LLM → regex fallback, bidirectional validation, deterministic coreference,
  and de-collision across question and retrieved chunks (`anonymize`, `anonymizeChunks`, `deanonymize`).
- `makeStreamDeanonymizer` — streaming-safe de-anonymization that never leaks a split placeholder.
- `openAICompatibleProvider` — pluggable LLM detection over any OpenAI-compatible Chat Completions API.
- `presets.swiss` and `presets.generic` regex pattern sets; fully configurable custom patterns.
- Regex-only mode (no LLM provider required).
- `PatternDef.validate` — optional second-stage predicate to cut false positives; `presets.generic` uses
  it for a Luhn check on credit-card candidates, and de-overlaps its phone/date/IP patterns.
- `openAICompatibleProvider` retries transient failures (network/timeout/429/5xx) via `retries` and
  `retryDelayMs` options; non-transient 4xx and malformed responses are not retried.
- Hardened the `nameHint` heuristic: `g`/`y` flags are stripped internally so `.test()` is stateless.
