## Changelog

### Memory default (15 Oct 2026)

- 15 Oct 2026 (build after this entry): default run memory is now 1024 MB via `defaultMemoryMbytes` (the old defaultRunOptions 512 MB was ignored so runs used 4096 MB; peak 32-47 MB). Measured on the example input: same output, see the public-15 remediation log. You can still choose more memory per run. No change to inputs, outputs or pricing.

### 1.0.0 (2026-10-11)

First release.

- **New companies** mode using the official Advanced Company Search (`/advanced-search/companies`): incorporation date range or "last N days", SIC 2007 codes plus plain-English **SIC keyword lookup**, status, type, subtype, location, name include/exclude. Postcode area/district and locality filters are applied before profile fetches. Size proxy and lead/risk-signal filters. Date ranges are split automatically when a query exceeds the API's 10,000-result paging cap.
- **Lookup** mode: company numbers (normalised and zero-padded) and names (official search with exact-match ranking).
- **Monitor** mode: per-company snapshots in a named key-value store. Detects changes in status, name, address, SIC codes, overdue flags, filings (plain-English descriptions), charges, insolvency and officers (opt-in). State only advances after a check has been delivered and billed.
- **SIC lookup** mode (free, no key).
- Normalised output: parsed registered office (postcode area/district), age, SIC descriptions, accounts and confirmation-statement dates and overdue flags, last accounts type and size proxy, charges and insolvency flags, previous names, register page link, lead and risk signals.
- Officers and PSC are **off by default**. When on, they're minimised to published identity fields (no addresses or occupations, never contact details).
- Shared token-bucket rate limiter that can't exceed the per-key limit in any 5-minute window. Global pause on 429 (Retry-After / X-Ratelimit-Reset aware), adaptive slow-down from X-Ratelimit-Remain, jittered retries for 5xx and network errors.
- Pay-per-event: `company`, `monitor-check`. Respects max cost per run, never charges error rows, and charges nothing in sample mode.
- Resumable after migration (delivered records are not repeated or re-charged).
- Sample mode with fictional fixture data when no API key is given.
