- Reject dash/colon MAC-format device names (e.g. 45-48-39-7F-73-C7)
from open mode — were slipping past is_generic_name()
- Add exponential backoff (1s, 2s) on Matrix 429/5xx, max 3 attempts —
startup burst was rate-limiting and dropping alerts
- Commit active scanner flag (scanning_mode=active) that was in working
tree but not in prior commit c0b91e9 despite the commit message
- Add 3 tests: MAC format filter, 429 retry success, 429 give-up
Fixes DevTrack #518
