with conn: context manager in Python sqlite3 doesn't respect busy_timeout
for the implicit BEGIN; under concurrent subprocess writes the transaction
would fail immediately. Replace with explicit BEGIN IMMEDIATE + retry loop
(6 attempts, 0.5s back-off) to handle WAL write contention.
credential_sniffer and credential_db both wrote to the same credentials.db
with different schemas; credential_db's executescript failed when creating
the crack_status index on an existing table that lacked that column.
Fix: split credential_db's schema init into table DDL + migration + indexes
so missing columns are added before index creation runs. Migration also
handles any future schema drift.
state.py: add 30s timeout + busy_timeout PRAGMA to write connection so
concurrent subprocess writes stop failing with 'database is locked'.
capture_bus.py: reconnect on ENETDOWN instead of aborting the capture
loop — mac_manager temporarily brings the interface down during MAC
rotation which was silently killing all packet capture.
- Add secure_wipe_file() to utils/crypto.py for file overwrites + deletion
- Add secure_wipe parameter to StateManager.stop() method
- Wipes all SQLite WAL files (.db, .db-wal, .db-shm) with 3 passes
- Normal exit now calls state.stop(secure_wipe=True) to clear state database
- Falls back to regular delete if secure wipe fails
- Prevents state.db from persisting on disk after shutdown
