## Changelog

### 2026-09-29

- Reliability: Valid GitHub, GitLab and Mastodon checks survive unrelated upstream failures; optional error audit rows distinguish unavailable checks from confirmed absence without profile charges.
- Safety: Verify exact public identity and reject unsafe Mastodon DNS targets and redirects; uncertain GitHub HTML absences no longer count as not found.

### 0.1.0

- Added public username account discovery across GitHub, GitLab, and selected Mastodon instances.
- Added normalized profile URLs, visible identity metadata, account states, and optional not-found audit records.
- Added bounded retries, a public GitHub profile fallback for anonymous API rate pressure, and fail-closed handling for blocked lookups.
- Limited each run to 100 combined platform checks and clarified that the start event covers bounded no-match lookup work.
