<id>urn:sha1:3aa372ccc3e11c837458b00088ffb6cbe99ff6ca</id>
<content type='text'>
- 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()-&gt;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

<id>urn:sha1:2ad2ed45f3ca82b1244a8b9e3e5efa89502413a9</id>
<content type='text'>
- 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

- config.c: parse accepted_mints JSON array, fallback to mint_url for backward compat
- cashu.c: cashu_is_mint_accepted() iterates accepted_mints[] instead of single mint_url

<id>urn:sha1:36fa7451a3be1c49932e944859364fe4e9f9fcc4</id>
<content type='text'>
- Fix buffer size for ["EVENT",...] wrapper: was 8+event_len+1,
  needed 10+event_len+2 (9 char prefix + ] + null). snprintf was
  truncating the closing bracket, causing relay JSON parse errors.
- Add write loop in ws_send_text for large payloads that don't fit
  in a single esp_tls_conn_write call.
- Change STA auth threshold from WPA2_PSK to WPA3_PSK for
  compatibility with WPA3 access points.
- Announcements now successfully stored on relay.primal.net!
