v0.3.2

What's new in v0.3.2

Fixes

• RUSTSEC-2025-0134: removed rustls-pemfile dependency (archived, unmaintained since August 2025). PEM parsing now uses rustls-pki-types::pem::PemObject which was already in the dependency tree via rustls. Zero new dependencies, one direct dependency removed.
• SonarCloud code duplication: reduced duplicated code from 41 blocks (736 lines) to 29 blocks (444 lines, all in carbon_profiles.rs data tables). Five refactorings:
  • impl_energy_state! macro in energy_state.rs eliminates the identical ScaphandreState / CloudEnergyState wrapper impls
  • build_per_trace_finding() helper in detect/mod.rs eliminates the duplicated Finding struct literal between n_plus_one.rs and slow.rs
  • emit_report_and_gate() helper in main.rs eliminates the duplicated format/emit/gate logic between cmd_analyze and cmd_tempo
  • FetchError + fetch_get() in http_client.rs eliminates the duplicated HTTP fetch logic between scaphandre/scraper.rs and cloud_energy/scraper.rs
  • test_scrape_fixture() helper in scaphandre/tests.rs eliminates duplicated test setup
• SonarCloud cognitive complexity: process_traces() refactored from 19 to under 15 by extracting record_slow_durations() and emit_findings_and_update_metrics()
