chore: checkpoint app work before firmware sync

Prefer reyna-cli (registry-addressed by device ID) over raw IPs/curl for the
Tactility LAN fleet. Document board ID->IP map (kidosos_* boards, esp32_screen,
little32), discover/devices/sysinfo/apps/install/run/report commands, and the
USB serial monitor for capturing ELF missing-symbol logs.

+- `device_get_by_name`, `device_get_first_by_type` (out-param API) → **Not exported** on flashed 0.8.0-dev (verified via serial on .129: `E ELF: Can't find symbol device_get_by_name`). The firmware exports the **legacy** `device_find_by_name` / `device_find_first_by_type` instead. Gotcha: newer SDK/CDN headers declare only `device_get_*` (so `device_find_*` fails to compile), but the flashed firmware only exports `device_find_*` (so `device_get_*` fails at load). Fix: call the exported legacy `device_find_*` and declare them locally in the app source since the SDK header dropped them:
+  ```c
+  extern struct Device* device_find_by_name(const char* name);
+  extern struct Device* device_find_first_by_type(const struct DeviceType* type);
+  ```
+  Verify the ACTUAL load on-device via serial (`/dev/cu.usbmodem*`, 115200) — `verify_symbols.py` compares against local firmware source and can report 0 missing even when the flashed firmware's export table differs.

+
+### Tactility SDK location (IMPORTANT)
+
+- When you run `tactility.py ... build` **without** `--local-sdk`, it auto-downloads the SDK to the per-app cache:
+  `Apps/<Name>/.tactility/<version>-<platform>/TactilitySDK` (e.g. `Apps/BookPlayer/.tactility/0.8.0-dev-esp32s3/TactilitySDK`).
+- **The freshly CDN-downloaded 0.8.0-dev SDK for esp32s3 is broken for this setup** — it fails at CMake with
+  `Failed to resolve component 'app-module' required by component 'TactilitySDK': unknown name` and also renames the
+  device API (`device_find_*` → `device_get_by_name/device_get_first_by_type` out-param style). It is a *different,
+  newer* SDK than the working one.
+- **The known-good SDK is the locally-cached copy** already present in the other apps'
+  `.tactility/0.8.0-dev-esp32s3/TactilitySDK` (the one that carries a `Drivers/` folder). It builds clean.
+- Workaround when a fresh download fails: copy the working cached SDK over the broken one:
+  ```bash
+  SRC=Apps/PipecatVoice/.tactility/0.8.0-dev-esp32s3   # known-good copy
+  DST=Apps/MyApp/.tactility/0.8.0-dev-esp32s3
+  rm -rf "$DST/TactilitySDK"; cp -R "$SRC/TactilitySDK" "$DST/"
+  ```
+  Then rebuild. (Resolving the root cause on the newer SDK is still TODO — consider pinning/downloading the cached zip
+  so this isn't needed per-app.)

+### Device discovery & management via reyna-cli
+
+`reyna-cli` (at `/Users/adolforeyna/.local/bin/reyna-cli`) wraps the Tactility LAN web API with a device registry
+(`~/.hermes/local_devices.yaml`). Prefer it over raw IPs/curl for fleet discovery and management. Boards are
+addressed by their stable registry **ID** (not IP — DHCP IPs change); `devices list` maps IDs→IPs.

-# DiscoveryMountain – Crash After Install – Root Cause & Fix
-
-**Board:** CYD ES3C28P (es3c28p) `192.168.68.132`  
-**Firmware:** 0.8.0-dev / IDF 5.5.2  
-**App ID:** `one.tactility.discoverymountain`  
-**Branch:** `personal/discovery-mountain-player` → merged into `main`  
-**Date:** 2026-07-21
-
----
-
-## Symptoms
-
-- After `tactility.py install 192.168.68.132`, device reboots or shows blue dialog `Application failed to start: missing symbol`
-- Serial logs: `E ELF: Can't find symbol ...`, then `Guru Meditation` (LoadProhibited, StoreProhibited, IllegalInstruction, Cache error)
-- Even when it did start, fetch fell back to 6 dummy episodes (`S01E01`…) with empty `audio_url`, so download always failed
-- When forced to download 4.3 MB MP3 from `http://192.168.68.110:8098/.../esp32_24k.mp3`, device hard-faulted during `play_task`
-
----
-
-## 1. Missing Symbol Loader Failures
-
-### Detected via `xtensa-esp32s3-elf-nm -D …elf | grep " U "`
-
-```
-U lv_font_montserrat_14
-U lv_roller_create
-U lv_roller_set_options
-U lv_roller_get_selected
-U lv_roller_set_selected
-U qsort
-U cJSON_* (via json component)
-```
-
-**Why:**
-- Firmware exports defined in `firmware/Modules/lvgl-module/source/symbols.c` – roller not exported
-- `lv_font_montserrat_14` is a data symbol, not exported (AGENTS.md known missing)
-- `qsort` not in `g_esp_libc_elfsyms` nor `main_symbols`
-- `cJSON` not exported – apps must vendor `cJSON.c` (see `BookPlayer`, `McpScreen`)
-
-**Fix:**
-- `manifest.properties` V1 INI → V2 flat:
-  ```
-  manifest.version=0.2
-  target.sdk=0.8.0-dev
-  target.platforms=esp32s3
-  app.id=one.tactility.discoverymountain
-  app.version.name=0.1.0
-  app.version.code=1
-  ```
-- `main/CMakeLists.txt`:
-  ```cmake
-  set(CJSON_SOURCE "$ENV{IDF_PATH}/components/json/cJSON/cJSON.c")
-  idf_component_register(SRCS ${SOURCE_FILES} ${CJSON_SOURCE}
-                         INCLUDE_DIRS Source "$ENV{IDF_PATH}/components/json/cJSON"
-                         REQUIRES TactilitySDK esp_http_client lwip)
-  ```
-- Replace roller with `lv_dropdown` (exported, see `symbols.c:272-291`)
-- Replace `qsort` with bubble sort
-- Replace `lv_font_montserrat_14` with `lvgl_get_text_font(FONT_SIZE_DEFAULT)` from `tactility/lvgl_fonts.h`
-
-After fix: `nm -D` shows no missing roller/qsort/font, verify script passes.
-
----
-
-## 2. Fatal `memset` Bug
-
-```c
-memset(&G,0,0); // size 0!
-```
-Static `G` is zero-initialized first boot, but second `onShow` leaves dangling `lv_obj_t*`, `play_handle`, etc.
-
-**Fix:** `memset(&G,0,sizeof(G))`
-
----
-
-## 3. Blocking LVGL Thread → Watchdog Reboot
-
-Original `onShow`:
-```c
-load_state(); fetch_data(); build_ui();
-```
-`fetch_data()` did 2× `esp_http_client_perform` with 8s timeout + `cJSON_Parse` of 91KB JSON on LVGL thread → 16s block → TWDT.
-
-**Fix:**
-- Build UI immediately with "Fetching..."
-- `xTaskCreate(fetch_task_fn,"dm_fetch",16384, ...)`
-- `fetch_task_fn` does `fetch_data()` in background, then `tt_lvgl_lock` to update labels
-- Same for download: `dl_task` 12288 stack
-
----
-
-## 4. `esp_http_client` vs Raw Sockets
-
-- `esp_http_client` failed on device for PB `http://192.168.68.110:8095` (returned chunked `1634\r\n{...}`), while `curl --http1.0` returned plain JSON.
-
-Raw socket version via `lwip_socket`, `ipaddr_addr`, `my_htons` (like `RobotArm`) is more reliable and allows PSRAM buffers.
-
-PocketBase:
-- `HTTP/1.1` → `Transfer-Encoding: chunked` → `1634\r\n{...}\r\n0\r\n\r\n`
-- `HTTP/1.0` → `Content-Length` absent, body until close → 5684 bytes seasons, 91293 bytes episodes
-
-**Fix:** Implement `http_get_raw` with:
-- PSRAM `heap_caps_malloc(65536, MALLOC_CAP_SPIRAM|8BIT)` growing to 600KB
-- Manual realloc via malloc+memcpy+free (avoid `heap_caps_realloc` not exported)
-- `strstr(buf,"\r\n\r\n")` to find header end
-- Detect `chunked`, decode hex chunk sizes via `strtol(hex, NULL, 16)`
-- Return de-chunked body
-
-Result: `DM: seasons items count 37`, `episodes items 232` (was fallback 37/6)
-
----
-
-## 5. Download Buffer & PSRAM
-
-- `dl_ep` used `esp_http_client` + `FILE*` with 2KB stack buf, but also `rename` with static `sd_path()` race
-- 4.3MB MP3 download needs streaming, not full RAM
-- `malloc(600000)` in internal heap (120KB free) → OOM → cache error
-
-**Fix:**
-- `make_sd_path(out,len,slug)` caller-provided buffer
-- `ensure_dir()` does NOT `mkdir("/sdcard")`
-- `dl_ep_raw` uses PSRAM `hdr 8192` + `recv_buf 4096`, streams directly to `FILE*`
-- Progress via `lv_label_set_text` under `tt_lvgl_lock`
-- LRU keeps 8 files, skips current playing
-
-Result: `DL done total 4329701 expected 4329701` – file correctly saved to `/sdcard/dm/`
-
----
-
-## 6. Audio: I2S Direct vs audio-stream + PSRAM
-
-Original used `i2s_controller_*` directly:
-```c
-device_lock(i2s_dev); i2s_controller_set_config(...); i2s_controller_write(...);
-```
-Conflicts with Audio service, no resampling, `vTaskDelete` while holding lock → deadlock, `samples*2` overflow for mono.
-
-**Fix (from BookPlayer):**
-- `find_audio_device()` via `device_find_by_name("audio-stream")`
-- `audio_stream_open_output(dev, cfg, &handle)`
-- `audio_stream_write(handle, pcm+off, ...)`
-- `close_stream()` via `audio_stream_close`
-- `wait_play_exit()` uses `tt_lvgl_unlock(); vTaskDelay(10); tt_lvgl_lock()` pattern
-- Buffers: `inbuf 16384` + `pcm 1152*2*2` from PSRAM
-- Volume scaling with proper clipping
-- Stack 12288 for play/dl/fetch (was 6144/8192 → overflow on cJSON 91KB)
-- Rate-limit `ui_timer` 500ms, only update bar if `pct != last_pct`
-
-**Playback crash – stack overflow:**
-```
-***ERROR*** A stack overflow in task dm_play has been detected.
-...
-Guru Meditation: BREAK instr at vTaskGenericNotifyGiveFromISR
-...
-PC : 0x40385c6e : vPortYieldFromInt
-```
-Root: `mp3dec_t` (~2KB) + large locals on 8192 stack + `malloc` for buffers + `fread` + `memmove` caused overflow.
-
-**Fix:**
-- Increase `dm_play` stack 8192 → 16384
-- Allocate `mp3dec_t* dec` from PSRAM via `heap_caps_malloc(..., SPIRAM|8BIT)` instead of stack
-- Allocate `inbuf` / `pcm` via `malloc` (internal) first, fallback PSRAM
-- Add ID3v2 skip:
-  ```c
-  uint8_t id3hdr[10];
-  if(fread(id3hdr,1,10,file)==10 && memcmp(id3hdr,"ID3",3)==0){
-    int sz = (id3hdr[6]&0x7F)<<21 | ...;
-    fseek(file, sz+10, SEEK_SET);
-  }
-  ```
-- Add logs `open_stream sr=%d ch=%d`, `open_stream ok`, `decoding frame buffered=%d`
-
-Result after fix:
-```
-DM: play task start /sdcard/dm/463_...mp3 size 4329701
-DM: open_stream sr=16000 ch=1
-esp32_i2s: Configuring I2S pins...
-Adev_Codec: Open codec device OK
-DM: open_stream ok
-```
-Stays alive 50s+ (previously crashed <1s).
-
-### 7. UI Progress Not Showing (user report: "It is playing now, the UI does not show the progress, maybe due to the autoplay.")
-
-Root:
-```c
-G.pos_sec += samples / info.hz; // integer division 1152/16000 = 0!
-```
-`pos_sec` never increments, so `pct = pos_sec*100/total_sec` stays 0, bar never moves. Also `last_pct` not reset on new episode.
-
-**Fix:**
-- Track `total_decoded_samples += samples; G.pos_sec = total_decoded_samples / hz;`
-- Reset `last_pct=-1` in `select_ep` and `start_idx_internal`
-- Keep `ui_timer` 500ms but always update time label, only bar when pct changes
-- Remove auto-play for final stable (user presses Play manually) – auto-play from `fetch_task` caused race with LVGL lock and hid progress issue
-
-After fix, progress bar moves and time label updates `0:01 / 4:30` etc.
-No immediate crash, stays alive 50s+ (previously crashed <1s).
-
-Remaining TODO: test actual audio output via speaker, try 44.1k file if 16k resampling still issues, add `taskYIELD()` and volume ramp to avoid pop.

-## Final State (2026-07-21 post-fix)
-
-- **Stable install:** No `missing symbol`, no `memset` garbage, no watchdog. Boots to launcher, shows UI, stays alive.
-- **Fetch:** `37 seasons / 232 episodes` via raw LWIP sockets + PSRAM 200KB buffer, `HTTP/1.0` to avoid chunked. Previously fallback 6 dummy.
-- **Download:** `DL done total 4329701 expected 4329701` via simple streaming `lwip_recv` → `FILE*` with PSRAM hdr/recv buffers, LRU keeps 8 files. Previously OOM and crash.
-- **Playback:** Fixed stack overflow in `dm_play` (8192 → 16384) + `mp3dec_t` heap allocated + ID3 skip. Now:
-  ```
-  DM: play task start ... size 4329701
-  DM: open_stream sr=16000 ch=1
-  DM: open_stream ok
-  ```
-  No immediate crash, stays alive 50s+. Audio output via `audio_stream` (ES8311) should work, but needs manual play test (auto-play removed for stability).
-- **UI:** Roller → dropdown, font → `lvgl_get_text_font`, no `HideStatusBar` per user request.
-- **Build:** Verified `nm -D` clean, `tactility.py build esp32s3 --local-sdk` ok.
-

-## TODO
-
-- [ ] Fix playback: skip ID3v2 before decode, try internal RAM for `mp3dec_t`, test with 44.1k mp3 from other episode (not `esp32_24k`)
-- [ ] Use `device_get_by_name` / `device_put` instead of deprecated `find`
-- [ ] Use `tt_app_get_user_data_path` for state file, not hardcoded `/sdcard/apps/...`

-# Discovery Mountain – Download & Playback Crash Report
-
-**Date:** 2026-07-25  
-**Device:** 192.168.68.133 (es3c35p, /dev/cu.usbmodem1101)  
-**App ID:** `one.tactility.discoverymountain` (DM) + `one.tactility.sddownloader` (SDDL) + `one.tactility.mp3player` (MP3)  
-**Firmware:** 0.8.0-dev / IDF 5.5.2 / Tactility SDK 0.8.0-dev
-
----
-
-## Summary – What is failing: DM or Downloader?
-
-**Both, same root cause: low internal heap (3–7 KB) + unsafe task handling.**
-
-- **DM fetch:** 1st launch OK (37/232), 2nd launch crashes with StoreProhibited.
-- **Downloader (SDDL):** S01E01 dummy (empty URL) causes gui stack overflow, S01E04 34 MB file causes gui overflow + phy_wakeup crash.

-
-- Download stalls at 21 KB / 36 MB, 12×15 s timeouts = 3 min blocked in `lwip_recv`
-- `onHide` did `vTaskDelay(100)` then `vTaskDelete(dl_handle)` while still blocked in recv → fd/socket/PSRAM leak → next WebServer request crashes.
-- Also `sdmmc_read_sectors: not enough mem 0x101` seen in many logs – DMA pool 32 KB exhausted.
-
-**Fix applied:**
-- Timeout 15 s → 5 s, max 12 → 5 (25 s max stall)
-- `onHide` graceful wait 2 s fetch / 3 s DL, only force delete after, no leak
-- `recv_buf`/`hdr` 8192 → 4096 PSRAM, `fflush` every 8 chunks, `vTaskDelay(10)` to let SDMMC recover
-- `sin_len = sizeof(sa)`, proper `my_htons` masking

-## 2. S01E01 – Empty URL + GUI Stack Overflow
-
-**Log:** `cu.usbmodem1101_20-33-06_s008.log`
-
-```
-[20:33:14] DM: connect fail 192.168.68.110:8095 → seasons fallback, episodes fallback → done 37/6
-[20:33:17] DM: Starting external SdDownloader for S01E01 -> /sdcard/dm/S01E01.mp3
-[20:33:17] SDDL: Should autostart has_url=1 has_path=1 url= path=/sdcard/dm/S01E01.mp3
-[20:33:17] xTaskCreate download_task
-***ERROR*** A stack overflow in task gui has been detected.
-Backtrace: 0x40385b29:0x3fcdb9d0 ...
-```
-
-- When PB fetch fails (connect fail), DM falls back to 6 dummy episodes `S01E01`…`S01E06` with **empty `audio_url`**.
-- User presses S01E01 → DM launches SdDownloader with empty URL → `download_one_file` checks `strlen(url)<8` → `Invalid URL` → calls `update_ui_status` + `set_result_and_close(false)` which did `vTaskDelay(1500)` + `tt_app_stop()` **from download_task** → deadlock: onHide waits for download_task, download_task waits in delay, gui task overflows.
-- Also `S01E01.mp3` path exists? No, so it tries download.
-
-**Fix:**
-- `try_external_downloader` now checks `strlen(audio_url)<8` → shows "No URL – fetch failed?" and returns false, no launch
-- `btn_dl_season_cb` filters `strlen>=8`
-- `SdDownloader` `set_result_and_close` no longer calls `tt_app_stop()` from download_task (just sets result, leaves app to be closed via Cancel button) → no deadlock
-- `SdDownloader` download_task stack 16384 → 8192 to save heap
-
-**User note:** "That episode should be on sd card already" – real S01E01 is `463_Discovering_Discovery_Mountain_S01E01.mp3` (4.3 MB), not dummy `S01E01.mp3`. Real file exists, dummy does not.

-## 3. S01E04 – 34 MB File, GUI Stack Overflow on DL Start
-
-**Log:** `cu.usbmodem1101_20-26-11_s006.log`
-
-```
-[20:28:43] DM: Starting external SdDownloader for 460_The_Lookout...S01E04 -> /sdcard/dm/460_...mp3
-[20:28:43] SDDL: Should autostart url=http://.../460_...mp3 path=/sdcard/dm/460_...mp3
-[20:28:43] xTaskCreate download_task res=1 handle=0x3fcc3f08
-
-***ERROR*** A stack overflow in task gui
-```
-
-- S01E04 is 34 MB (`file_size 34460594`). Download task created, but gui task overflows immediately, before any DL log.
-- Root: `lru_check` had `FE files[200]` → 200*304=60 KB on stack of download_task (12 KB stack) → overflow. Also `sort_eps` had `EpInfo t` 500 bytes on stack inside double loop.
-- `ensure_parent_dir` had 512+512 stack, `req[512]`, etc.
-
-**Fix:**
-- `lru_check`: `files` allocated from PSRAM via `heap_caps_malloc(200*sizeof(FE))`
-- `sort_eps`: temp `EpInfo t` allocated from PSRAM
-- `ensure_parent_dir`: rewritten without `strtok_r` (not exported) and without large stack, using manual parsing and `strncat`
-- Download task stack 16K → 8K, fetch task stays 12K, heap check before socket.

-```
-
-- 1st fetch after boot OK, 2nd fetch (app reopened) crashes 11 ms after first page GET, before header_end.
-- Backtrace shows crash in **LVGL timer task**, not fetch task: `lv_timer.c:107` → `ui_timer`
-- `ui_timer` (200 ms) was doing heavy work: `save_current_ep_pos()` + `save_state()` (cJSON create, print, fopen, fwrite) every 5 sec when playing. Called from GUI task with limited stack → StoreProhibited when trying to write to flash 0x82... (string literal in flash?).
-- Also `G` global is 240 KB (400*492) BSS in DRAM, plus `saved_pos` 40 KB = 280 KB, leaving free heap 50 KB → after first fetch cJSON 10 KB nodes, heap fragments to 3-7 KB → `MemoryChecker: Internal memory low: 3607/7279/7435`
-
-**Fix:**
-- `ui_timer`: early return if `G.fetching`, remove periodic `save_state()` (saving is done explicitly in `select_ep`, `go_next`, `onHide`, `onResult`)
-- `AppCtx.MAX_EPS` 400→250, `title` 128→64, `audio_url` 256→128, `MP3_BUF` 16384→4096 → size 240 KB → ~100 KB
-- `fetch_task` stack 16384→12288, `onShow` heap log, `xTaskCreate` result log
-- Pagination 100/page → 50/page (now 25/page) with 300-400 ms delay between pages to let heap recover, `fields=season_num` and `fields=title,slug,season_num,episode_num,audio_url` to cut JSON 91 KB → 42 KB → 9 KB/page

-## 5. DL Season Button – IntegerDivideByZero in Bundle
-
-**Log:** `cu.usbmodem1101_16-57-59_s014.log`
-
-```
-[17:34:06] episodes page 1 got 50 items
-[17:34:06] Guru IntegerDivideByZero PC 0x42014cf3
-Backtrace: 0x42014cf0(hashtable_policy.h:534) 0x42014dac(unordered_map.h:988) 0x42014345(tt_bundle.cpp:46 putInt32) 0x4237a4d3(app)
-```
-
-- Pressing **DL Season** during fetch → `G.ep_cnt` only 50 (partial), `G.fetching` true, but button didn't check fetching → `btn_dl_season_cb` called `tt_bundle_alloc` + 20× `putString` (url+path) while internal heap low from cJSON → `unordered_map` bucket_count=0 → `% bucket_count` → divide by zero.
-
-**Fix:**
-- `btn_seasons_cb` and `btn_dl_season_cb` now check `if(G.fetching) return;`
-- `btn_dl_season_cb`: `missing_idx[50]` → `[10]` to avoid LVGL stack overflow, heap check `>15 KB` before alloc, and per-put heap check `>8 KB` else abort with "Low memory, try 1 by 1"
-- Also filters `strlen(audio_url)>=8`
-
----
-
-## 6. Play Button – Now Opens Mp3Player, Returns Timestamp
-
-**Previous:** DM had internal `play_task` using `audio_stream` directly. User reported "pres play nothing happened" because audio-stream device not found when launched from DM (DM still held it).
-
-**Fix in `player.c`:**
-```c
-stop_playback_sync(); wait_play_exit(); close_overlay();
-BundleHandle b = tt_bundle_alloc();
-putString("file", fpath); putInt32("pos_sec", saved);
-tt_app_start_with_bundle("one.tactility.mp3player", b);
-```
-- `onResult` in DM now handles Mp3Player return:
-  - `optInt32("pos_sec"/"timestamp")` → `set_saved_pos_for_slug`
-  - Updates UI `S01 E02 * • 0:07`, `Resume – tap Play`
-  - No autoplay after DL or after Mp3Player (per request)
-
-**Mp3Player (`one.tactility.mp3player`) fixes:**
-- Retry finding audio device 5×200 ms (was failing when launched from DM)
-- Tracks `pos_sec = total_decoded_samples / hz`, `total_sec` estimate
-- `onHide` returns bundle `pos_sec`, `timestamp`, `file`, `finished`, `success`
-- `onHide` now closes audio stream **before** alloc result to free heap, frees buffers before bundle, only puts 2 ints to avoid OOM, no SD file write in low heap
-
-**Tested on 133:**
-```
-[20:03:30] DM: Launching Mp3Player for /sdcard/dm/463_...mp3 pos 4
-[20:03:31] Mp3Player: Found audio-stream device 0x3fca480c
-[20:03:31] Starting MP3 playback size 4329701 resume=4
-[20:03:31] Audio stream opened 16000 Hz, 1 ch
-[20:03:56] onHide start pos_sec=15
-[20:03:59] Set result bundle pos_sec=15
-[20:03:59] onHide returning pos_sec=15 total_sec=269
-[20:03:59] DM: onResult result=1 pending_idx=0 cur_idx=0 → saved pos 15

-## 7. SdDownloader – Now Batch + Headless (per your latest spec)
-
-**Manifest:** `one.tactility.sddownloader`, 30 KB, 0 missing symbols
-
-**UI:** Only bar, `% (3/10)`, detail `x / y KB`, URL/path labels read-only, status, Cancel. No input fields.
-
-**Args via bundle (no manual input):**
-- Single: `url`, `path`, `override` bool (default false → fail if exists)
-- Batch (full season): `count` int, `url_0`/`path_0` … `url_n`/`path_n`, `override` bool
-- Example from DM `btn_dl_season_cb`:
-```c
-bundle.putInt32("count", 7);
-putString("url_0", "http://.../S02E01.mp3"); putString("path_0", "/sdcard/dm/...");
-...
-tt_app_start_with_bundle("one.tactility.sddownloader", b);
-```
-
-**Returns bool:**
-```c
-bundle.putBool("success", true/false);
-putInt32("success_count"), "fail_count", "total_count", "bytes", "path", "error"
-setResult(OK/ERROR, bundle)
-```
-DM `onResult` shows `DL: X ok, Y fail` and refreshes `seen` flags.
-
-**Robustness:**
-- 8 KB stack (was 16 KB), 4 KB PSRAM buf, 15 s timeout, 5 retries
-- `ensure_parent_dir` mkdir -p without `strtok` (not exported)
-- `stat` check for exists → fail if not override
-- No `tt_app_stop()` from download task (caused deadlock + gui stack overflow for S01E01 empty URL)
-
----
-
-## Current Builds on 133
-
-- `DiscoveryMountain.app` 80 KB (was 70 KB) – entry 0x4237543c, 118 undef, 0 missing – 37/232 fetch, seasons dropdown works, no autoplay, DL Season 10 max, external Mp3Player/SdDownloader, no fullscreen covering (root now child of parent, overlays closed before launch)
-- `SdDownloader.app` 30 KB – 74 undef, 0 missing – batch 10, file-exists check
-- `Mp3Player.app` 40 KB – 0 missing after adding `esp_http_client` to REQUIRES – returns timestamp
-
----
-
-## Still Open / Next
-
-- Second fetch after app restart still StoreProhibited at 0x4238a8c0 (PC in app) during first page GET – likely `cJSON_Parse` + `has_slug` stat + low heap after first fetch. Mitigation: reduce `MAX_EPS` further or move `G` to PSRAM with `EXT_RAM_ATTR` (tried, caused other crash), or free `G.eps` between fetches.
-- S01E01 dummy fallback (empty URL) now shows "No URL – fetch failed?" instead of crash, but ideally should never appear if fetch succeeds. Ensure PB at `192.168.68.110:8095` is reachable (seen `connect fail` when WiFi bcn_timeout).
-- Mp3Player close takes 2.5 s (force delete after 50 tries) – should be optimized to not need force delete.
-
----
-
-## Reproduction Steps for S01E04 Crash (you reported)
-
-1. Clean fetch fails → fallback 37/6 dummy episodes `S01E01`…`S01E06` with empty URL
-2. Press S01E01 → DM tries external DL with empty URL → SDDL `url=` empty → `Invalid URL` → `set_result_and_close` did `tt_app_stop()` from download task → deadlock → gui stack overflow
-
-Fixed by: empty URL check in `try_external_downloader` + `btn_dl_season_cb` + removing `tt_app_stop()` from download task.
-
-For real S01E04 (34 MB, `460_...`), previous crash was gui stack overflow right after `xTaskCreate` – fixed by reducing download_task stack 16K→8K and moving `files[200]` 60KB array from stack to PSRAM in `lru_check`.
-
----
-
-## Files Changed
-
-- `Apps/DiscoveryMountain/main/Source/app_context.c` – added `pending_dl_idx`, `root`
-- `app_context.h` – reduced `MAX_EPS` 400→250, `MP3_BUF` 16K→4K, `title` 128→64, `audio_url` 256→128, added `root`, `pending_dl_idx`, batch fields in SDDL
-- `network.c` – 50/page pagination (was 400), fields filter, 8K internal buf, detailed logs for connect
-- `storage.c` – `sort_eps` temp from PSRAM, `lru_check` files from PSRAM (was 60KB stack)
-- `download.c` – stubbed to only overlays (internal DL removed)
-- `player.c` – simplified to only external launchers, no internal `play_task`, added `download_season()`
-- `ui.c` – `build_ui(parent)` uses parent, not `scr_act()`, root stored, 2 buttons 48% (Seasons + DL Season), `ui_timer` early return if fetching, `btn_dl_season_cb` with heap checks
-- `main.c` – onShow heap log, xTaskCreate 12288, onResult handles both Mp3Player timestamp and SdDownloader batch, onHide does NOT clear `pending_dl_idx`, deletes root
-- `SdDownloader/main/Source/main.c` – new app, batch support, file-exists + override logic, returns bool
-- `Mp3Player/main/Source/main.c` – returns `pos_sec`/`timestamp`, retry audio device, auto-finds test file if no bundle
-
----
-
-## How to Test Full Season Download
-
-1. Open DM → wait `fetch done 37/232`
-2. Tap `Seasons` → S01 → tap `DL Season`
-3. Should show `Starting DL 6 eps S01` → launches SDDL → bar shows `3/6: 45%` etc.
-4. On finish, DM shows `DL: 6 ok, 0 fail` and refreshes `*` markers
-5. Tap episode with `*` → Play → launches Mp3Player → plays from saved pos → close → DM shows `Resume • 0:12`

+# Live Captions
+
+ESP32-S3 external app that streams 16 kHz signed-16-bit mono microphone PCM to the Mac mini Hermes voice gateway and renders its live draft/final captions. It stores **only final captions** on the device SD card in `/sdcard/captions/YYYY-MM-DD.txt`.
+
+## Configuration
+
+Before packaging, place `config.json` in the app's user-data directory (not source control):
+
+```json
+{
+  "server_url": "ws://192.168.68.102:8642/api/esp32/voice/ws",
+  "device_id": "your-registered-device-id",
+  "api_key": "device-profile-key"
+}
+```
+
+The app never retries automatically: connection failure remains `FAILED` until the user selects **Start** again. **Stop** sends the gateway `stop` event, waits for the final caption, appends it to that day’s text file, then returns to idle.

-# LuaGame - Lua Interpreter Game Engine
-
-External ELF app that runs Lua games on Tactility OS (ES3C35P 320x480 tested on 192.168.68.107).
-
-## How it works
-- Embeds Lua 5.4.7 source (no external dependency, avoids missing symbol issues)
-- Lua init + game loop run in dedicated 16K stack FreeRTOS task to avoid GUI task (4096 bytes) stack overflow
-- Game framebuffer: 240x240 RGB565 in PSRAM, rendered via LVGL canvas (`lv_canvas_set_buffer` + `lv_obj_invalidate` with `tt_lvgl_lock`)
-- Direct framebuffer text using 8x8 bitmap font (`font8x8.h`) – 17+ FPS vs 15 FPS with LVGL labels
-- **Sys API** (original Tactility breakout.lua):
-  - `sys.log(msg)`
-  - `sys.clear(hexColor)`
-  - `sys.print(x,y,text,hexColor)` – direct FB via `draw_text8`
-  - `sys.rect(x,y,w,h,hexColor,filled)` – border or filled
-  - `sys.circle(x,y,r,hexColor,filled)` – midpoint + filled scan
-  - `sys.line(x0,y0,x1,y1,hexColor)`
-  - `sys.touch() -> pressed, tx, ty` (touch mapped to 240 game space)
-  - `sys.tone(note, duration, waveform, volume)` → SfxEngine `playNote`
-  - `sys.sfx(name)` → SfxEngine `play(SfxId)` mapping: confirm, coin, hurt, gameover, levelup, brickhit, etc.
-- **Pico API** compatibility (from `/Users/adolforeyna/Projects/pico-bare-metal/Adolfo/basic1/games/lua_examples`):
-  - `game.width()`, `height()`, `set_frame_updates(bool)`, `exit()`, `game.vars` persistent table
-  - `renderer.clear(white)`, `pixel(x,y,on)`, `line(x0,y0,x1,y1,on,width)`, `rect(x,y,w,h,on,filled)`, `circle(x,y,r,on,filled)`, `triangle(x0,y0,x1,y1,x2,y2,on,filled)`, `text(x,y,txt,on)`, `text_scaled(x,y,txt,on,scale)` (scale 1-4)
-  - `INPUT` constants: `NONE=0, TOUCH_DOWN=1, TOUCH_MOVE=2, TOUCH_UP=3, BUTTON_0=4, BUTTON_1=5, FRAME_TICK=6, GESTURE=7`
-  - Event system: generates `TOUCH_DOWN/MOVE/UP` from touch state + `FRAME_TICK` every frame, calls `update(event)` returning bool redraw
-  - Detection: if source contains `renderer.` → Pico mode, else sys mode
-- Embedded games:
-  - `embedded_breakout_lua_src` – fast breakout (ball 4.5 vs 2, paddle 0.25 spin) – default
-  - `pico_games.h` auto-generated with 17 games: 2048, air_hockey, asteroids, ball, breakout, counter, flappy_bird, lunar_lander, memory_match, pacman, pong, simon_says, snake, solitaire, tetris, tic_tac_toe – tested Pong runs at 17.5 FPS
-- File loading: PSRAM buffer + `luaL_loadbuffer` to avoid `luaL_loadfile` stack issues, supports SD paths `/sdcard/lua/*.lua`
-
-## Symbol fixes
-Previous missing: `clearerr`, `clock`, `getenv`, `gmtime`, `setlocale`, `setvbuf`, `tmpfile`, `tmpnam`, `ungetc`, `lv_canvas_get_draw_buf`, `lv_draw_buf_invalidate_cache`, `lv_image_cache_drop`.
-Fixed by local stubs + avoiding unexported APIs, only `lv_canvas_create`, `lv_canvas_set_buffer`, `lv_obj_invalidate`, `tt_lvgl_lock/unlock`.
-
-## Performance
-- Ball speed: 2 → 4.5 (2.25x faster), configurable in embedded string
-- FPS: 15 → 17.5 FPS after direct FB text + dedicated game loop task
-- Memory: internal low ~2-3KB (PSRAM used for FB and Lua heap), stable, no crash 20s+
-
-## Build / Install
-```bash
-cd /Users/adolforeyna/Projects/Tactility/apps
-unset PYTHONPATH; unset PYTHONHOME
-export IDF_PYTHON_ENV_PATH=/Users/adolforeyna/.espressif/python_env/idf5.3_py3.9_env
-source /Users/adolforeyna/esp/esp-idf/export.sh
-export TACTILITY_SDK_PATH=/Users/adolforeyna/Projects/Tactility/firmware/release/TactilitySDK
-export ESP_IDF_VERSION=5.5
-python tactility.py Apps/LuaGame build esp32s3 --local-sdk
-curl -X PUT http://192.168.68.107/api/apps/install -F "file=@Apps/LuaGame/build/LuaGame.app"
-curl -X POST "http://192.168.68.107/api/apps/run?id=one.tactility.luagame"
-```
-
-## Porting Pico Games
-Yes – all 17 examples from `pico-bare-metal/Adolfo/basic1/games/lua_examples` use:
-- `game.vars` state machine
-- `renderer.*` monochrome API (boolean on/off → mapped to white/black RGB565)
-- `INPUT.TOUCH_*` + `FRAME_TICK`
-
-Our engine now implements compatibility shim in C (see `l_renderer_*`, `l_game_*`, INPUT table). Pong tested:
-```
-[LuaGame] using Pico test game: Pong (7538 bytes)
-Pong initialized
-FPS 17.5
-```
-Other games (snake, tetris, 2048, etc.) should work same – they are ~50-880 lines, no file I/O, pure math/table. To add selector UI, list `pico_games[]` via LVGL list and load selected `src`.
-
-## TODO
-- Game selector UI (menu_wrapper + game_wrapper, hide/show)
-- Copy pico examples to SD via USB MSC or bundle selector
-- Audio mapping for Pico games (currently sys.sfx only, could map to renderer events)
-- Scale canvas to full 320x480 or dynamic `game.width/height`
-- Fix internal memory low warnings (reduce SfxEngine voices or Lua heap)

-  Notes:
-
-  (*) Opcode OP_LFALSESKIP is used to convert a condition to a boolean
-  value, in a code equivalent to (not cond ? false : true).  (It
-  produces false and skips the next instruction producing true.)
-
-  (*) Opcodes OP_MMBIN and variants follow each arithmetic and
-  bitwise opcode. If the operation succeeds, it skips this next
-  opcode. Otherwise, this opcode calls the corresponding metamethod.
-
-  (*) Opcode OP_TESTSET is used in short-circuit expressions that need
-  both to jump and to produce a value, such as (a = b or c).
-
-  (*) In OP_CALL, if (B == 0) then B = top - A. If (C == 0), then
-  'top' is set to last_result+1, so next open instruction (OP_CALL,
-  OP_RETURN*, OP_SETLIST) may use 'top'.
-
-  (*) In OP_VARARG, if (C == 0) then use actual number of varargs and
-  set top (like in OP_CALL with C == 0).
-
-  (*) In OP_RETURN, if (B == 0) then return up to 'top'.
-
-  (*) In OP_LOADKX and OP_NEWTABLE, the next instruction is always
-  OP_EXTRAARG.
-
-  (*) In OP_SETLIST, if (B == 0) then real B = 'top'; if k, then
-  real C = EXTRAARG _ C (the bits of EXTRAARG concatenated with the
-  bits of C).
-
-  (*) In OP_NEWTABLE, B is log2 of the hash size (which is always a
-  power of 2) plus 1, or zero for size zero. If not k, the array size
-  is C. Otherwise, the array size is EXTRAARG _ C.
-
-  (*) For comparisons, k specifies what condition the test should accept
-  (true or false).
-
-  (*) In OP_MMBINI/OP_MMBINK, k means the arguments were flipped
-   (the constant is the first operand).
-
-  (*) All 'skips' (pc++) assume that next instruction is a jump.
-
-  (*) In instructions OP_RETURN/OP_TAILCALL, 'k' specifies that the
-  function builds upvalues, which may need to be closed. C > 0 means
-  the function is vararg, so that its 'func' must be corrected before
-  returning; in this case, (C - 1) is its number of fixed parameters.
-
-  (*) In comparisons with an immediate operand, C signals whether the
-  original operand was a float. (It must be corrected in case of
-  metamethods.)

-** Some notes about garbage-collected objects: All objects in Lua must
-** be kept somehow accessible until being freed, so all objects always
-** belong to one (and only one) of these lists, using field 'next' of
-** the 'CommonHeader' for the link:
-**
-** 'allgc': all objects not marked for finalization;
-** 'finobj': all objects marked for finalization;
-** 'tobefnz': all objects ready to be finalized;
-** 'fixedgc': all objects that are not to be collected (currently
-** only small strings, such as reserved words).
-**
-** For the generational collector, some of these lists have marks for
-** generations. Each mark points to the first element in the list for
-** that particular generation; that generation goes until the next mark.
-**
-** 'allgc' -> 'survival': new objects;
-** 'survival' -> 'old': objects that survived one collection;
-** 'old1' -> 'reallyold': objects that became old in last collection;
-** 'reallyold' -> NULL: objects old for more than one cycle.
-**
-** 'finobj' -> 'finobjsur': new objects marked for finalization;
-** 'finobjsur' -> 'finobjold1': survived   """";
-** 'finobjold1' -> 'finobjrold': just old  """";
-** 'finobjrold' -> NULL: really old       """".
-**
-** All lists can contain elements older than their main ages, due
-** to 'luaC_checkfinalizer' and 'udata2finalize', which move
-** objects between the normal lists and the "marked for finalization"
-** lists. Moreover, barriers can age young objects in young lists as
-** OLD0, which then become OLD1. However, a list never contains
-** elements younger than their main ages.
-**
-** The generational collector also uses a pointer 'firstold1', which
-** points to the first OLD1 object in the list. It is used to optimize
-** 'markold'. (Potentially OLD1 objects can be anywhere between 'allgc'
-** and 'reallyold', but often the list has no OLD1 objects or they are
-** after 'old1'.) Note the difference between it and 'old1':
-** 'firstold1': no OLD1 objects before this point; there can be all
-**   ages after it.
-** 'old1': no objects younger than OLD1 after this point.
-*/
-
-/*
-** Moreover, there is another set of lists that control gray objects.
-** These lists are linked by fields 'gclist'. (All objects that
-** can become gray have such a field. The field is not the same
-** in all objects, but it always has this name.)  Any gray object
-** must belong to one of these lists, and all objects in these lists
-** must be gray (with two exceptions explained below):
-**
-** 'gray': regular gray objects, still waiting to be visited.
-** 'grayagain': objects that must be revisited at the atomic phase.
-**   That includes
-**   - black objects got in a write barrier;
-**   - all kinds of weak tables during propagation phase;
-**   - all threads.
-** 'weak': tables with weak values to be cleared;
-** 'ephemeron': ephemeron tables with white->white entries;
-** 'allweak': tables with weak keys and/or weak values to be cleared.
-**
-** The exceptions to that "gray rule" are:
-** - TOUCHED2 objects in generational mode stay in a gray list (because
-** they must be visited again at the end of the cycle), but they are
-** marked black because assignments to them must activate barriers (to
-** move them back to TOUCHED1).
-** - Open upvales are kept gray to avoid barriers, but they stay out
-** of gray lists. (They don't even have a 'gclist' field.)

-** such that t[i] is present and t[i+1] is absent, or 0 if t[1] is absent
-** and 'maxinteger' if t[maxinteger] is present.)
-** (In the next explanation, we use Lua indices, that is, with base 1.
-** The code itself uses base 0 when indexing the array part of the table.)
-** The code starts with 'limit = t->alimit', a position in the array
-** part that may be a boundary.
-**
-** (1) If 't[limit]' is empty, there must be a boundary before it.
-** As a common case (e.g., after 't[#t]=nil'), check whether 'limit-1'
-** is present. If so, it is a boundary. Otherwise, do a binary search
-** between 0 and limit to find a boundary. In both cases, try to
-** use this boundary as the new 'alimit', as a hint for the next call.
-**
-** (2) If 't[limit]' is not empty and the array has more elements
-** after 'limit', try to find a boundary there. Again, try first
-** the special case (which should be quite frequent) where 'limit+1'
-** is empty, so that 'limit' is a boundary. Otherwise, check the
-** last element of the array part. If it is empty, there must be a
-** boundary between the old limit (present) and the last element
-** (absent), which is found with a binary search. (This boundary always
-** can be a new limit.)
-**
-** (3) The last case is when there are no elements in the array part
-** (limit == 0) or its last element (the new limit) is present.
-** In this case, must check the hash part. If there is no hash part
-** or 'limit+1' is absent, 'limit' is a boundary.  Otherwise, call
-** 'hash_search' to find a boundary in the hash part of the table.
-** (In those cases, the boundary is not inside the array part, and
-** therefore cannot be used as a new limit.)
