<id>urn:sha1:e366ceb336550a72c76efea4c98a2a08cca27bce</id>

New modules:
- mining_payment.c/h: hashprice calc (nbits-&gt;difficulty-&gt;sat/GH/s/day),
  share validation, client stats, allotment conversion (ms + bytes)
- stratum_client.c/h: SV1 upstream pool connection (subscribe/authorize/submit)
- stratum_proxy.c/h: Local SV1 TCP server for downstream miners, job broadcast
- sw_miner.c/h: Software SHA256d miner (ESP32 CPU fallback)
- asic_miner.c/h: ASIC detection stub (BM1366/BM1368 SPI)

Config:
- config.h/c: mining_payout_mode_t enum (auto/pool/upstream/proxy_only),
  stratum pool settings, mining port, hashprice override, sandbox mint access
- Defaults fill nostr_seed_relays (8/8) and nostr_relays (4/4) with fast relays

Integration into existing modules:
- session.h/c: payment_method_t enum (CASHU/MINING/BYTES)
- firewall.h/c: firewall_set_mining_port(), firewall_set_sandbox_mint_access()
- tollgate_api.c: GET /mining/job, POST /mining/share, GET /mining/stats
- tollgate_client.h/c: TG_CLIENT_MINING state, mining discovery tag parsing
- tollgate_main.c: mining init in start_services(), stratum_client_tick() in loop
- captive_portal.c: tabbed Cashu/Mine UI with live hashrate polling

Unit tests (69 new assertions across 4 suites):
- test_mining_payment (23 tests): nbits-&gt;difficulty, hashprice, client stats, allotment
- test_stratum_proxy (21 tests): job set/get, stats, type validation
- test_session_payment_method (12 tests): PAYMENT_METHOD enum, bytes/cashu methods
- test_tollgate_client_mining (20 tests): mining tag parsing, discovery struct
- test_firewall_sandbox (16 tests): client grant/revoke, max clients, setters

Enhanced test stubs:
- BaseType_t/pdPASS in freertos/task.h
- lwip: sockets.h, etharp.h, prot/ip.h, prot/ip4.h, prot/tcp.h, netif.h
- dns_server.h, esp_wifi_ap_get_sta_list.h

Build fixes:
- cvm_server.c: replace esp_timer_get_time() with xTaskGetTickCount(),
  fix process_relay_message() 3-arg call to 2-arg, add WS keepalive ping
- stratum_proxy.c: widen task_name buffer 16-&gt;20
- sw_miner.c: add missing #include esp_random.h
- nucula_src: save_proofs() moved to public in wallet.hpp

Nostr relay updates:
- nostr_seed_relays: +relay.anzenkodo.workers.dev, +nostr.koning-degraaf.nl,
  +knostr.neutrine.com, +nostr.einundzwanzig.space (8/8 slots)
- nostr_relays: +relay.anzenkodo.workers.dev, +nostr.koning-degraaf.nl (4/4 slots)

Squash merge of feature/multi-mint-support (21 commits):

Multi-mint wallet:
- Accept payments from 4 mints: minibits, coinos, 21mint, lnvoltz
- Periodic health probing (300s interval, 3 recovery threshold)
- Multi-wallet init with nucula_wallet_init_multi()
- /mints and /wallet API endpoints

WPA auto-detect:
- wifi_auth_mode config field (default WPA2, supports WPA3)
- Runtime mapping to wifi_auth_mode_t in STA config

Display gating:
- display_enabled config field (default true)
- Guards display_init/display_update per-board

Bug fixes:
- 3s delay before service start prevents lwip mem_free assertion
- Real npub in discovery (identity_get()-&gt;npub_hex)
- Health probe interval 300s (production value)
- Duplicate services_start_task call removed
- UTF-8 arrow replaced with ASCII in log message

Tests: 61+14 unit tests passing, firmware builds clean

<id>urn:sha1:236b61d619f60d941119d891dc1c6a49b504a880</id>
<content type='text'>
- Add esp_netif_set_dns_info() on AP interface so DHCP advertises
  AP as DNS server to clients (fixes captive portal on GrapheneOS)
- Embed price and mint URL directly in portal HTML via server-side
  template substitution (no JavaScript fetch to :2121 needed)
- Move supported mints section below the token input field
- Add Playwright tests: no unresolved placeholders, embedded mint/price,
  DOM order verification (14/14 passing)

<id>urn:sha1:38aa9ec3801f5895e09866fe92cb8e44fb987cee</id>
<content type='text'>
- Derive unique SSID (TollGate-{MAC4}{MAC5}) and AP IP (10.{b5}.{subnet}.1)
  from factory MAC — boards no longer conflict
- Board A: TollGate-377C @ 10.55.85.1, Board B: TollGate-5050 @ 10.80.10.1
- Captive portal detection URIs return 200 with portal HTML (matching
  esp32-mesh working approach) instead of 302 redirect
- Dynamic AP IP in portal HTML via __AP_IP__ template substitution
- Supported mints section in portal page (shows mint URL, tap to copy)
- Fixed mint URL to testnut.cashu.space (was stale in SPIFFS)
- DoT reject server on port 853 for DNS-over-TLS fallback
- DNS hijack: NXDOMAIN for all non-A queries, no forwarding for unauthed
- Playwright tests updated for 200 response on detection URIs
- Phase 2 test suite: 20/21 pass (test 22 expiry ping route issue)
- Tests 25-27 deferred to Phase 3 (Board B as second client)

<id>urn:sha1:50b5975ac8793d6d820c35b5999f8a909f64e71b</id>
<content type='text'>
- Add DoT reject server on port 853 (TCP RST forces DNS-over-TLS fallback)
- DNS hijack returns NXDOMAIN for all non-A query types (no forwarding for unauthed)
- Shorter TTL on hijack responses (10s) for faster captive detection
- Explicit 302 redirect handlers for /generate_204, /hotspot-detect.html, etc.
- HTTP and DNS request logging for debugging captive detection
- Per-MAC tracking in firewall (find_by_mac, get_mac_for_ip with ARP fallback)
- Session MAC tracking (session_find_by_mac)
- Phase 2 test 18: add route through TollGate before ping test
- All 17 Phase 2 tests pass (15-21 + whoami + portal form)

<title>Phase 2 WIP: Cashu payment endpoints, session tracking, updated checklist</title>

<id>urn:sha1:1263d86314fc0760d9be8eea415ccecbc047a5eb</id>
<content type='text'>
- Add cashu.c/h: Cashu token decode (cashuA/base64url), proof state check via mint API, allotment calculator
- Add session.c/h: time-based session management with allotment/expiry, spent secret tracking
- Add tollgate_api.c/h: HTTP server on :2121 with GET / (kind=10021 discovery), POST / (payment processing), /usage, /whoami
- Update captive portal HTML: replace Grant Free Access with Cashu token paste form + Pay &amp; Connect button
- Update tollgate_main.c: wire in session manager, TollGate API, 1s session tick loop
- Add tests/phase2.mjs: Phase 2 test suite (discovery, invalid token, wrong mint, valid payment)
- Update CHECKLIST.md: reflect Phase 1 complete, Phase 2 in progress with known bugs

Known issues (not yet flashed):
- Stack overflow crash in httpd POST handler (need stack_size=16384 + heap allocations)
- cashu_decode_token uses 2KB stack buffer (needs heap alloc)
- Mint URL should be testnut.cashu.space (nofee.testnut has API compat issues)

<id>urn:sha1:a7d0a672d59bf8985a6fc0e61b49015fabd96513</id>
<content type='text'>
- Fix WiFi init order: netif creation before esp_wifi_init, set mode before set_config
- Replace broken netif input filter with NAPT on/off per authentication state
- NAPT disabled by default, enabled when client granted, disabled on revoke
- Fix test helpers: use -I wlp59s0 for ping, handle nslookup exit code 1
- All 20 API tests pass, all 6 smoke tests pass
