- Pin both stages to alpine:3.23 (was floating 'alpine').
- Multi-stage: separate runtime image without rust+cargo+sdk, just python3.
- venv for Python deps (PEP 668 on modern Alpine blocks system pip).
- start.sh: -c <fieldMappings.yaml> (was .json — upstream renamed),
drop -t which now means --template (Jinja2) not tmpdir.
- test_smoke.sh: fetch Yamato sample-evtx on demand, scan, verify JSON
+ log produced, count Sigma rule hits.
- fetch-test-data.sh + .gitignore for test-data/.
Validated end-to-end on amd64 Linux: 5/5 PASS, 39 hits, Zircolite v3.6.3
with 2160 rules.
