Phase 7: eliminate shims - consumer files use component headers directly

2026-05-23T00:02:22+00:00

- Deleted standalone shims: session.c/h, cashu.c/h, mining_payment.c/h, firewall.c/h - Updated captive_portal.c, tollgate_api.c, tollgate_main.c, mcp_handler.c, cvm_server.c, sw_miner.c, stratum_client.c to include component headers - Moved tollgate_ip4_canforward_filter() lwIP hook into tollgate_main.c - Fixed all unit tests to use component API (test_cashu, test_session, test_mining_payment, test_stratum_proxy, test_session_payment_method, test_firewall_sandbox, test_mcp_handler) - Removed deleted source files from Makefile targets - All 21 unit tests pass, ESP-IDF build passes

Phase 5: Wire main/ shims to components/tollgate_core

2026-05-22T22:40:28+00:00

- session.c/h: thin shim casting session_t* <-> tg_session_t*, delegates to tollgate_core_session_* - firewall.c/h: keeps ESP-specific lwIP hooks, delegates allowlist to tollgate_core_fw_* - cashu.c/h: shim delegates to tollgate_core_cashu_*, multi-mint via config directly - mining_payment.c: shim delegates to tollgate_core_mining_* - tollgate_main.c: calls tollgate_core_init(tollgate_esp_get_platform(), ap_ip) in start_services() - tollgate_esp: removed target_sources for standalone sources, depends on tollgate_core component - tollgate_core component: added tollgate_core_get_platform(), tg_payment_method_t enum - Unit tests: updated Makefile for component source compilation, all 22 tests pass - Hardware verified: Board A boots, AP visible, 5/6 smoke tests pass (internet test needs upstream WiFi)

feat: per-client NAT filtering via LWIP_HOOK_IP4_CANFORWARD

2026-05-17T11:09:31+00:00

- Add lwip_tollgate_hooks.h defining LWIP_HOOK_IP4_CANFORWARD macro - Inject hook into lwIP build via CMakeLists.txt ESP_IDF_LWIP_HOOK_FILENAME - Filter forwarded packets by source IP against firewall allowed list - Only filter packets from AP subnet (10.192.45.0/24), allow all others - Fix byte order bug: use network byte order for firewall_is_client_allowed - NAT always enabled, removed global NAT toggle functions - Remove spent-secret tracking from session.c (mint is authority) - Remove unused get_ap_netif() function - Reduce API server stack from 32KB to 16KB (fixes ESP_ERR_HTTPD_TASK) - Add esp_random.h stub for unit tests - All 186 unit tests passing - Verified on hardware: block->pay->allow->revoke->block E2E works

feat(phase6): bytes-based billing - dual metric support

2026-05-16T23:20:07+00:00

- session_create_bytes() + session_add_bytes() for bytes-metric sessions - session_is_expired() dispatches on config metric (bytes vs milliseconds) - cashu_calculate_allotment() unified dispatcher for both metrics - tollgate_api discovery/usage/session_event use configured metric - config: metric field defaults to 'bytes', step_size_bytes=22020096 (21MB) - 14 new unit tests (148 total passing) - ASSERT_EQ_UINT64 macro added to test framework

Testing infrastructure: AGENTS.md rules + unit test framework + geohash tests (11/11 pass)

2026-05-16T20:01:49+00:00

- Add AGENTS.md: full project context + mandatory testing rules for AI sessions - Add tests/unit/ with host-compiled C unit test infrastructure - Clean stubs approach: ESP-IDF type stubs in tests/unit/stubs/, no source modifications - Fix geohash.c bit extraction bug (3-byte span) found by unit tests - test_geohash: 11/11 passing with reference vectors (Munich, NYC, origin, boundaries)
