- 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.

Full working closed-loop eSIM provisioning stack (spec in claude.md / plan/):
Flask API, SQLite subscriber store, credential/profile generator, Open5GS
and free5gc core adapters, captive portal, operational scripts, systemd
units, network configs, and a 44-test suite.
Profile generation currently returns a mock JSON profile; real SGP.22
generation via pySim is the planned Phase-2 upgrade.
Fixes two bugs found while getting the suite green:
- generate_imsi hardcoded a 10-digit MSIN, producing 16-digit IMSIs for a
3-digit MNC; MSIN length is now 15 - len(mcc) - len(mnc).
- check_rate_limit compared timestamps as strings across mismatched formats
(SQLite CURRENT_TIMESTAMP vs Python isoformat); both sides now normalized
via SQLite datetime() so the window check is chronologically correct.
Add .gitignore for venv, caches, runtime config.yaml, and databases.
