A ashkan@beigi.net c6423b1bad Harden: concurrency safety (db lock timeout, cache lock, retry, portal) ... - get_connection sets PRAGMA busy_timeout so concurrent writers under a threaded server wait instead of hitting "database is locked". - Provision retries credential generation on IMSI/ICCID collision (up to 5x) instead of surfacing a duplicate as a 500. - Guard the module-level profile cache with a threading.Lock. - Captive portal disables the activate button while a request is in flight to avoid double provisioning. Tests: +2 (collision retry + give-up); 84 pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>			2026-07-01 06:16:25 +00:00
