- PatternDef.validate + Luhn-gated credit-card detection; de-overlap the generic phone/date/IP patterns; presets.swiss unchanged (production behavior) - strip g/y flags from nameHint so .test() is stateless (latent footgun) - openAICompatibleProvider: bounded retry on transient failures (network / timeout / 429 / 5xx), configurable via retries + retryDelayMs - eslint + prettier + vitest coverage (97%); CI runs lint/format/coverage - docs: README badges + new-option docs, SECURITY.md, issue/PR templates 26 tests passing; build emits ESM+CJS+types.
