<id>urn:sha1:19e175b1c1dea54efb61e8040ffdfa973fbac5d5</id>
<content type='text'>
- Removed standalone TLS worker task (couldn't allocate 16KB internal stack)
- Added wallet receive queue to mint_health task (already has 16KB stack + working TLS)
- health_task processes wallet tokens between probe intervals (1s poll)
- tls_worker_set_queue() registers queue from mint_health_start()
- Fallback to synchronous receive if queue not available
- Added freertos/queue.h and tollgate_api.h stubs for unit tests
- Added BaseType_t/UBaseType_t/TickType_t/pdFALSE to FreeRTOS stub
- Full payment round-trip confirmed: 2 payments → 41 sat balance

<title>feat(wallet): lazy keyset loading with exponential backoff + jitter</title>

<id>urn:sha1:243e4808246555f86d464d1c476681a902e644ff</id>
<content type='text'>
- Remove eager load_keysets() from init_wallet(), load on first use
- Add ensure_keysets() with binary exponential backoff + random jitter
- Guard all wallet operations (receive, send, melt, swap_all) with ensure_keysets()
- Skip checkstate on TLS failure, let wallet swap verify proofs instead
- Pin HTTP server to core 0 (fixes TLS cert verification in checkstate)
- Rewrite nucula http.c to use manual open/write/read (same as working health probe)
- Disable hardware MPI (CONFIG_MBEDTLS_HARDWARE_MPI=n)
- Add http.h stub for unit tests

Known issue: progressive TLS failure after 2-3 connections (PK verify 0x4290),
wallet receive swap fails. Needs deeper mbedTLS/PSRAM investigation.

<id>urn:sha1:716daafce3eaa5ebfd246c1ef9915a2972b4c6fd</id>
<content type='text'>
Root cause: mbedtls SSL buffers (16KB) couldn't allocate from fragmented
internal RAM (largest block 8KB). Fix by lowering SPIRAM_MALLOC_ALWAYSINTERNAL
from 16KB to 4KB, allowing SSL buffers to go to PSRAM.

Additional fixes:
- DNS server binds to AP IP only (prevents self-hijacking)
- start_services() moved from esp_timer (2KB stack) to dedicated FreeRTOS
  task (16KB stack) — was causing stack overflow with dynamic buffers
- Mint health probe now logs errors and exposes last_err in API
- Debug endpoint shows internal/PSRAM heap breakdown and DNS resolve test
- Enabled CONFIG_MBEDTLS_DYNAMIC_BUFFER for better memory management
- Board C config: mint_url → testnut-nutshell.mints.orangesync.tech

<id>urn:sha1:09c9a6425587e8f71a8089815aaae11e51bdfef9</id>
<content type='text'>
Root cause: xTaskCreate from within IP event handler never scheduled the
services_start_task on ESP32-S3. Replaced with esp_timer one-shot callback.

Also moved captive_portal_start() into start_ap_services() so the portal
starts immediately when the AP comes up, not waiting for STA GOT IP.

Added /debug endpoint for runtime diagnostics.
Added captive_portal diagnostic getters.

<content type='text'>
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
