2026-05-19feat(mining): integrate mining subsystem into existing modulesYour Name
- CMakeLists.txt: add 6 mining sources + tcp_transport dependency - config.h/c: mining_payout_mode_t enum, mining config fields, JSON parsing - tollgate_main.c: mining init in start_services(), stratum_client_tick in main loop - tollgate_api.c: GET /mining/job, POST /mining/share, GET /mining/stats endpoints - session.h/c: payment_method_t enum (CASHU/MINING/BYTES) - firewall.h/c: sandbox allowlist for mining port + mint URLs - tollgate_client.h/c: TG_CLIENT_MINING state, mining discovery tag parsing - captive_portal.c: tabbed UI with Cashu/Mine tabs, live hashrate polling
2026-05-19feat: local Nostr relay with relay selection, sync, and integration testsYour Name
Local Nostr relay (NIP-01) on port 4869 with LittleFS 4MB storage. All events published locally first, then synced to public relays via REQ-diff. Relay selection via NIP-11 HTTP probing with NIP-77 scoring and auto-failover. Components: - wisp_relay: 16-file local relay (ws_server, storage_engine, sub_manager, broadcaster, relay_validator, router, handlers, rate_limiter, nip11, deletion, flash_monitor, relay_types) - esp_littlefs: LittleFS VFS integration (git submodule) - negentropy: for future NIP-77 binary sync (git submodule) New source files: - local_relay.c/h: thin wrapper for relay init/start/publish - relay_selector.c/h: NIP-11 probe + scoring + auto-failover - sync_manager.c/h: REQ-diff sync (primary 30min, fallback 6h) Bug fixes: - config.c: use-after-free (cJSON_Delete before seed_relays/sync parsing) - local_relay: moved init to app_main for boot-time start (not gated on STA IP) Flash layout: 4MB LittleFS partition at 0x500000 for relay_store Test results (Board B, live hardware): - Smoke: ping + HTTP 4869 + NIP-11: PASS - NIP-11 info document: 10/11 PASS - WS pub/sub (connect, REQ/EOSE, EVENT/OK, CLOSE, concurrent): 6/6 PASS - Unit tests (relay_validator + relay_selector): 13/13 PASS Hardware test make targets in physical-router-test-automation/: - make relay-build, relay-flash-b, relay-test-smoke/nip11/pubsub/sync/full
2026-05-19feat: ContextVM (MCP over Nostr) server with full integrationYour Name
Complete CVM implementation: persistent WebSocket relay listener, kind 25910 event subscription, MCP protocol handlers, CEP-6 announcements, 10 MCP tools, per-board hardware locks, WiFi EU regulatory fix. Architecture: - cvm_server.c: WS relay listener, kind 25910 subscription, MCP dispatch - mcp_handler.c/h: 10 MCP tools (get_config, set_config, get_balance, wallet_send, get_sessions, get_usage, set_payout, set_metric, set_price, wallet_melt) - Responses published via existing WS connection (not new TLS) - Auth check: only owner npub accepted - CEP-6: kinds 11316 (server), 11317 (tools), 10002 (relay list) - WS ping/pong keepalive every 30s, 60s TLS read timeout Critical fixes: - WiFi country code DE (ESP-IDF defaults to CN, breaks EU APs) - Subscription #p filter must be array not string - Use-after-free: tags_str freed before nostr_event_to_json - MCP responses via existing WS (ESP32 can't open multiple TLS) - EVENT msg buffer underflow, WS frame masking, TLS write loop Per-board hardware locks: - Lock files in physical-router-test-automation/locks/ - lock-a/b/c, unlock-a/b/c targets in 3 Makefiles - All hardware-touching targets require board lock Verified on Board B via relay.primal.net: - 282 unit tests passing (61 CVM + 60 MCP + 161 existing) - MCP initialize roundtrip: PASS - tools/list: PASS - tools/call get_config: PASS - tools/call get_balance: PASS - tools/call set_price: PASS (write operation) - CEP-6 announcements (11316, 11317, 10002): all accepted by relay - WiFi STA connection (EnterSSID-2.4GHz): PASS with country code DE - Board A WiFi confirmed hardware issue (not firmware)

2026-05-16Unique SSID/IP per board + captive detection fix + mint list in portalYour Name
- 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)
2026-05-16Phase 2 WIP: token decode works, TLS checkstate succeeds (crashes after ↵Your Name
response) - cashu.c: dynamic json_buf sizing (was 2048 stack, now heap based on token length) - cashu.c: strip trailing newline/CR from token input (cashu CLI appends 'Balance: 0 sat') - cashu.c: esp_crt_bundle_attach for HTTPS to mint API - cashu.c: esp_http_client_open/write/fetch_headers/read pattern for HTTPS POST - cashu.c: remove debug b64url_decode logging - tollgate_api.c: loop httpd_req_recv for full body (was single call, missed TCP segments) - tollgate_api.c: stack_size=32768 for TLS in httpd handler - config.c: fix default mint URL from nofee.testnut to testnut.cashu.space - CMakeLists.txt: add esp-tls dependency for cert bundle - CHECKLIST.md: updated with infrastructure status and TDD plan Known issue: device reboots after checkstate returns 966 bytes with status=200. Crash likely in post-response processing (JSON parse or session create).
