- Add `toISOFromTokens` to extract ISO dates from noisy values (e.g. ".ua" `0-UANIC 20111004161638`, `OK-UNTIL 20261004161638`)
- Parse compact `YYYYMMDDHHMMSS` (.ua) and `YYYYMMDD` (.br, including ticket suffix like `20260319 #31066859`) date formats
- Parse ordinal/prose dates used by .gg/.je (`28th December 2018 at 05:54:43.861`)
- Teach `parseKeyValueLines` to collect indented continuation lines for header-style blocks (.gg/.je) without mistaking URLs or times as key separators
- Extract .gg/.je expiry from `Relevant dates:` sentences and split inline registrar URL (`epag (http://www.epag.de)`)
- Map .ua `status: OK-UNTIL <timestamp>` to `expirationDate` when no explicit expiry field is present
- Treat RDAP `pending release` / `release process: waiting` statuses as `isRegistered: false` (previously always `true`)
- Mark WHOIS `.br` `release process: waiting` as available
- A server that accepts the connection and closes it without sending data now rejects with `errorCode: "no_data"` and `stage: "read"` instead of resolving with an empty string
- OS-level `ETIMEDOUT` errors are mapped to the same `timeout` / `stage` shape as the library's own timer, with `stage` derived from whether the socket had connected yet
- `ECONNRESET` after data arrives is no longer marked `partial: true`; it was a complete reply and the reset just signalled the end of the stream
- `stage` on `LookupAttempt` is now documented as covering all WHOIS failures (not only timeout failures)
- Resolve `LookupResult` with an `attempts` array describing every network operation (phase, server, duration, error) so failures recovered by fallback remain visible
- Add `deadlineMs` option for a hard cap on total lookup time, distinct from per-operation `timeoutMs` (lowered default from 15 s to 10 s)
- Add `errorCode` (machine-readable `LookupErrorCode`), `errorPhase`, and `errorServer` to `LookupResult`; `timeout` covers both per-op and deadline timeouts, `aborted` means the caller's signal fired
- WHOIS timeouts now distinguish `connect` vs `read` stage and resolve with partial text (marked `partial: true`) when data arrived before the socket stalled
- Drop Node 18 support; minimum engine is now 20
- Introduced `collectWhoisReferralChain` to gather WHOIS responses while avoiding contradictory data from registrars.
- Updated `lookupDomain` to utilize the new chain collection method, ensuring TLD responses are prioritized.
- Added `mergeWhoisRecords` function to consolidate WHOIS data from multiple sources.
- Enhanced tests for referral handling and merging behavior, ensuring accurate data retention across scenarios.
