- 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 support2026-05-16T23:20:07+00:00Your Nameyou@example.com2026-05-16T23:20:07+00:00urn:sha1:edd125d0e3fe5fe7c0edf30c429723f3b0120c68
- 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+00:00Your Nameyou@example.com2026-05-16T20:01:49+00:00urn:sha1:347d29658959c7e4b368a15134c183f4ce7a25bc
- 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)
