## Changelog

### 2026-09-01

- Fleet-wide health check. Verified against this Actor's real run history: 30-day success rate, output row counts, per-field fill rates, and peak memory against the configured memory limit.
- Reviewed for the failure patterns that have cost this fleet runs — unguarded proxy setup, retry loops that can outlast the run's own time budget, and full-page HTML parsing that can exhaust a small container.
- No change to input, output fields or scraping logic.

### 2026-08-11

- Maintenance release: refreshed the build and dependencies.
- Re-verified live execution, non-empty structured output and dataset field/type integrity.
- Reviewed reliability (retries, pagination) and output quality as part of a full-fleet QA pass.

### 1.0.0 — 2026-08-01

- Initial publish-ready implementation.
- Streams the official EPA ECHO weekly ZIP without loading the complete archive into memory.
- Added state, facility name, NAICS, program and current-violation filters.
- Added normalized compliance/enforcement fields plus an optional complete official source row.
- Made raw fields opt-in after a cloud throughput benchmark to keep 100K+ exports efficient.
- Normalized each 140-column source row only once, eliminating the main cloud CPU bottleneck.
- Added input, output and dataset schemas with a buyer-friendly overview.
- Added retry handling, empty-result diagnostics and a 500,000-item run cap.
- Validated with default and alternative live-source inputs.
