- Add display_enabled config field (default true, parsed from config.json)
- Guard display_init/display_update behind display_enabled check
- Fix discovery pubkey: replace hardcoded all-zeros with identity_get()->npub_hex
- Revert MINT_HEALTH_PROBE_INTERVAL_S from 30 (testing) to 300 (production)
- Remove duplicate services_start_task call in IP event handler
- Fix UTF-8 arrow in STA auth threshold log message
- Gitignore compiled test binaries (test_mcp_handler, test_mint_health, etc.)
- Remove tracked test binaries from git
Verified on Board B (stable):
- make test-discovery-b: pubkey=d6bfe100..., metric=milliseconds, price_per_step tags
- make test-mints-b: 4 mints listed with reachable field
- Wallet: 40 sats balance with 4 proofs from previous payment
- All API endpoints responding (discovery, mints, wallet, whoami, portal)
- 75/75 unit tests passing

flash-a and flash-b now require lock-a/lock-b to be held before
flashing. Prevents cross-session hardware conflicts when multiple
LLM agents share the same ESP32 boards.
Lock infrastructure matches main repo and price-discovery worktrees:
- HARDWARE_LOCK_DIR = physical-router-test-automation/locks
- require_lock_a/require_lock_b macros
- lock-a/lock-b/unlock-a/unlock-b/force-unlock-a/force-unlock-b/lock-status targets

- Add wifi_auth_mode config field (WPA2/WPA3) parsed from config.json
- Default to WPA2 (accepts both WPA2 and WPA3 networks)
- Replace hardcoded WIFI_AUTH_WPA3_PSK with runtime threshold mapping
- Reduce MINT_HEALTH_PROBE_INTERVAL_S from 300 to 30 for testing
- Add 3s delay before service start + 5s DNS stabilization for health probes
- Fixes lwip mem_free crash caused by concurrent HTTP at boot
Verified on hardware:
- STA connects to WPA2 home router (Got IP:192.168.2.16)
- All 4 mint health probes complete successfully
- API endpoints return correct data with reachable mint filtering
- 4/4 wallets initialized with real keysets from live mints
test: burst-fetch integration test — all endpoints verified passing2026-05-18T20:02:53+00:00Your Nameyou@example.com2026-05-18T20:02:53+00:00urn:sha1:a09be62cfab9a1d7f37c697c44c71aed70536e8c
Burst-fetch approach grabs all data in rapid succession before board reboots.
All 10 previously-failing tests now pass:
- GET /mints: 4 mints with boolean reachable field
- GET /wallet, /usage, /whoami: all respond correctly
- POST bad token: payment-error-invalid
- POST non-accepted mint: payment-error-mint-not-accepted
- Portal: all 4 mints listed, mint-dot indicators, JS fetches :2121/mints

- 247-line integration test covering 8 sections, 32+ assertions
- Tests: config, mint list, health status, payment routing, wallet, sessions
- Fake V3 token generation for payment routing tests
- Retry logic for unstable board connectivity
- Detailed test report with results, bugs found, and untested scenarios

- Guard tollgate_config_get_next_wifi against network_count=0
- Add fallback parsing for wifi_ssid/wifi_password flat fields
- Add heap info to API server failure log for debugging
- All 75 unit tests passing
