feat: ContextVM (MCP over Nostr) server with full integration
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)

111### WiFi Debugging Findings (Board A — 94:a9:90:2e:37:7c)
112- **Symptom:** `WIFI_REASON_AUTH_EXPIRED` (0x200) on all upstream APs
113- **APs tested:** EnterSSID-2.4GHz (ch11, WPA2), c03rad0r (not in range), laptop hotspot (ch6, WPA2)
114- **Modes tested:** APSTA (ch1/6/11), STA-only (no AP at all)
115- **MAC tested:** Custom (derived from nsec) and factory MAC
116- **Result:** Auth fails in ALL configurations, even STA-only 1m from laptop hotspot
117- **Root cause hypothesis 1:** Missing WiFi country code — ESP-IDF defaults to CN regulatory domain, boards are in DE. Different TX power limits and channel parameters may cause APs to ignore ESP32 auth frames.
118- **Root cause hypothesis 2:** Hardware antenna issue on Board A — needs testing on other boards to confirm
119- **Spectrum:** Dense environment (ch1: 2 APs, ch6: 4 APs, ch11: 4 APs) but laptop connects fine at 100%
120- **Next step:** Add `esp_wifi_set_country_code("DE")` and test Board A, then Board B/C if needed
121
122### Per-Board Hardware Locks
123- [x] Lock files in `physical-router-test-automation/locks/` (board-a.lock, board-b.lock, board-c.lock)
124- [x] `lock-a/b/c`, `unlock-a/b/c`, `force-unlock-a/b/c` targets
125- [x] All hardware-touching targets require corresponding board lock
126- [x] Read-only targets (build, cvm-pubkey, lock-status) work without lock
127- [x] Board port mapping updated: A=ACM0, B=ACM1, C=ACM3

476### Phase 7: ContextVM Server (MCP over Nostr) — COMPLETE 476### Phase 7: ContextVM Server (MCP over Nostr) — REWRITE IN PROGRESS
477 477
478**Goal:** Remote configuration of ESP32 TollGate via ContextVM — services communicate over Nostr using public keys as addresses. Exposes configuration as MCP tools accessible by both humans and AI agents. 478**Goal:** Full ContextVM protocol implementation — ESP32 acts as an MCP server discoverable on the Nostr network via CEP-6 public announcements, communicating via kind 25910 ephemeral events.
479 479
480**New files:** `main/cvm_server.c`, `main/cvm_server.h`, `main/nip44.c`, `main/nip44.h`, `main/mcp_handler.c`, `main/mcp_handler.h` 480**Protocol:** ContextVM transports MCP JSON-RPC 2.0 messages over Nostr. Server is identified by its npub (derived from nsec). Clients discover the server via kind 11316 announcements, then communicate via kind 25910 ephemeral events.
481 481
482#### Architecture 482#### Architecture
483 483
484ContextVM uses MCP (JSON-RPC 2.0) over NIP-44 encrypted Nostr DMs: 484```
4851. ESP32 subscribes to Nostr relays for DMs addressed to its npub 485Client (nak/ContextVM SDK)
4862. Incoming DMs are NIP-44 decrypted, parsed as MCP JSON-RPC requests 486 → publishes kind 25910 to relay ({"method":"tools/call","params":{"name":"get_config"}})
4873. Dispatched to registered tool handlers 487 → ESP32 cvm_server reads from persistent WebSocket subscription
4884. Responses sent back via NIP-44 encrypted DM 488 → parses MCP JSON-RPC from event content
489 → dispatches to mcp_handler.c
490 → publishes kind 25910 response back to relay
491 → client receives response via subscription
492```
493
494#### ContextVM Event Kinds Used
495
496| Kind | Purpose | CEP |
497|------|---------|-----|
498| 25910 | MCP request/response transport (ephemeral) | Draft spec |
499| 11316 | Server announcement (replaceable) | CEP-6 |
500| 11317 | Tools list announcement (replaceable) | CEP-6 |
501| 10002 | Relay list (replaceable) | CEP-17 (NIP-65) |
502
503#### MCP Protocol Flow
489 504
490#### MCP Tools Exposed 5051. ESP32 publishes kind 11316 (server announcement) + kind 11317 (tools list) + kind 10002 (relay list) on startup
5062. ESP32 opens persistent WebSocket to relays, subscribes to `{"kinds":[25910],"#p":["<npub>"]}`
5073. Client sends kind 25910 `initialize` request
5084. ESP32 responds with kind 25910 `initialize` result (capabilities, serverInfo)
5095. Client sends `notifications/initialized`
5106. Client calls `tools/list` or `tools/call`
5117. ESP32 dispatches to `mcp_handler.c`, returns result
512
513#### Encryption
514
515Phase 7a ships with **plaintext** kind 25910 events. Encryption (CEP-4: NIP-44 gift wrap) is deferred to Phase 7b. The `support_encryption` tag is NOT included in announcements until Phase 7b.

595- [ ] Clean up debug logging (Sending WS response, WS send result → DEBUG level)
596- [ ] Document Board A hardware WiFi issue in AGENTS.md
597
598### Integration Testing (needs Board B + relay.primal.net)
599- [ ] tools/list response via kind 25910
600- [ ] tools/call set_price via kind 25910
601- [ ] tools/call get_sessions via kind 25910
602- [ ] tools/call get_usage via kind 25910
603- [ ] Non-owner auth rejection via live relay
604- [ ] Verify board npub on contextvm.org/servers

592**Rationale:** The mint's `cashu_check_proof_states()` already catches double-spends over HTTP. `nucula_wallet_receive()` → `swap()` registers proofs as spent and replaces them. After a successful receive, the old token is useless. Local tracking adds no security, wastes 6.5KB RAM, and is lost on reboot anyway. 676**Rationale:** The mint's `cashu_check_proof_states()` already catches double-spends over HTTP. `nucula_wallet_receive()` → `swap()` registers proofs as spent and replaces them.

678### Phase 8: TFT Display (JC3248W535 / AXS15231B) — IN PROGRESS
679
680**Goal:** Add TFT display support to the JC3248W535 board for QR code rendering + status text. Display cycles between a Wi-Fi QR code (so customers can connect) and a portal URL QR code (for direct portal access).
681
682**Hardware:** JC3248W535 board — ESP32-S3, AXS15231B 320x480 QSPI TFT, capacitive touch
683**Pin mapping:** CS=45, CLK=47, D0=21, D1=48, D2=40, D3=39, BL=1, Touch SDA=4, Touch SCL=8
684
685#### Components Created
686
687| Component | Path | Purpose |
688|-----------|------|---------|
689| `components/qrcode/` | `qrcoded.c/h` + CMakeLists.txt | QR code generation (ported from NSD, MIT license) |
690| `components/axs15231b/` | `axs15231b.c/h` + CMakeLists.txt | AXS15231B QSPI display driver |
691| `main/display.c/h` | Display abstraction | FreeRTOS display task, state machine, QR cycling |
692| `main/font.c/h` | 8x8 bitmap font | ASCII 32-127 for status text rendering |
693
694#### Display States
695
696| State | Screen | QR Content |
697|-------|--------|------------|
698| `DISPLAY_BOOT` | "TollGate starting..." | None |
699| `DISPLAY_READY` | QR code + SSID label | Cycles: Wi-Fi QR ↔ Portal URL QR every 5s |
700| `DISPLAY_PAYMENT_RECEIVED` | Green "Paid! Access granted" | None (2s, then READY) |
701| `DISPLAY_ERROR` | Red "No upstream" | None |
702
703#### Wi-Fi QR Code Format
704
705Uses the standardized ZXing `WIFI:` URI scheme — natively recognized by Android and iOS camera apps:
706
707```
708WIFI:S:<escaped_ssid>;T:nopass;;
709```
710
711**Special character escaping**: `;`, `:`, `\`, `,`, `"` are backslash-escaped in the SSID field per spec.
712
713**Example:**
714```
715SSID: TollGate-C0E9CA → WIFI:S:TollGate-C0E9CA;T:nopass;;
716SSID: My;WiFi:Test → WIFI:S:My\;WiFi\:Test;T:nopass;;
717```
718
719When scanned, the phone **automatically connects** to the TollGate AP — then the captive portal takes over for payment.
720
721#### QR Cycling
722
723The display alternates between two QR modes every 5 seconds:
7241. **Wi-Fi QR** — `WIFI:S:...;T:nopass;;` — auto-connects phone to AP
7252. **Portal URL QR** — `http://10.x.x.1/` — direct link to captive portal
726
727Label text below QR changes to indicate current mode: "Scan to connect" vs "Portal URL".
728
729#### Display Driver Architecture
730
731- **Interface**: Single-line SPI (MOSI on D0/GPIO21) — simpler than QSPI, reliable for V1
732- **Framebuffer**: 307,200 bytes (480x320x2 RGB565) in PSRAM via `heap_caps_malloc`
733- **Flush**: 10 chunks of 32KB via `spi_device_polling_transmit`
734- **Rotation**: Landscape (MADCTL=0x60, MX|MV)
735- **Backlight**: GPIO1 active-high
736
