a2nr 8e89fde3c1 fix: docked editor panel height + quiz image parser + assets dir config 
- fix(layout): editor-area docked mode sekarang height:70vh (sebelumnya
  max-height:85vh tanpa height, menyebabkan tab Arduino/velxio menciut
  ke 150px karena iframe tidak punya intrinsic height)
- fix(layout): tambah overflow:hidden pada velxio/flowchart/quiz panel
  untuk mencegah nested scrollable flex collapse
- feat(quiz): parser image dari 'image:' directive dan markdown ![alt](path)
  di question flashcard; konversi bare filename ke /assets/ path
- feat(assets): ASSETS_DIR derived dari CONTENT_DIR untuk support
  custom content directory (bukan hardcoded 'assets')
- fix(quiz): QuizTab container gunakan flex:1+min-height:0 (bukan height:100%)
- chore: hapus placeholder examples/assets/put_your_image.here

a2nr 156480b26f Merge dev → master: USB deployer get_sync fix (buffered pump) 
Consolidates all dev work including the orphaned-read race fix:
- Single read-pump feeds a FIFO ByteStreamBuffer; readExact/drain/
  serial monitor consume from buffer (no orphaned reader.read()).
- DTR timing 50ms+100ms, port reuse, pre-sync drain.
- Vitest + ByteStreamBuffer unit tests (7 pass).
- APP_VERSION 18 for SW cache-bust.

Verified on CH340 (1a86:7523): INSYNC 0x14 + STK_OK 0x10
received cleanly, deploy succeeds.

a2nr 98adc0b860 fix(usb-deployer): review fixes — reset pumpRunning on exit, clear buffer on readExact timeout 
WARN-1: pumpRunning now reset to false when the pump loop exits via
{done} or error, so future startPump() isn't a silent no-op.
WARN-3: readExact clears rxBuffer on timeout to avoid stale bytes
leaking into the next non-retried STK500 command.

a2nr 6f2f9c589a chore(frontend): bump APP_VERSION to 18 for SW cache-bust 
Service worker evicts old caches on activate, so users always
get the new usb-deployer bundle with the read-pump fix instead
of a stale cached one.

a2nr 056b1a47b6 refactor(usb-deployer): serial monitor + flashBuffer + lifecycle use pump 
- startSerialMonitor/setBaudRate stop+restart pump, subscribe rxBuffer.onData
- flashBuffer stops pump, reuses/reopens port, starts pump, drains before sync
- stopReaderWriter now just releases locks; cleanup stops pump first
- remove dead keepReading field

a2nr f7c088013a fix(usb-deployer): read from rxBuffer, kill orphaned-read race in get_sync 
readExact and drainStray now consume the FIFO buffer fed by the pump
instead of calling reader.read() directly. No orphaned reader.read()
promise can swallow optiboot INSYNC/OK replies anymore. This is the
core fix for "get_sync failed after N attempts".
 2026-07-19 19:06:44 +07:00
a2nr 121d592ce0 feat(usb-deployer): add read pump + start pump after pair 
Single pump loop becomes the only reader.read() caller, feeding
rxBuffer. Serial monitor + readExact/drain will consume from the
buffer (next tasks). Build passes.
 2026-07-19 19:05:54 +07:00
a2nr bf4b1a4932 feat(frontend): add vitest + ByteStreamBuffer FIFO for orphan-read fix 
Test runner setup (vitest) plus deadline-based FIFO buffer that
becomes the single sink for serial bytes. readExact keeps
partial bytes buffered on timeout — the exact case that dropped
optiboot INSYNC/OK replies under the orphaned-reader race.
7 unit tests pass.

a2nr 2a09ee77ab feat(embed): add raw HTML embed fence with bleach sanitization 
- Add embed markdown fence: user pastes raw embed HTML code
  (from Canva/YouTube/Google Docs Share→Embed) into lesson markdown
  and slide content. Backend sanitizes via bleach (whitelist
  tags/attrs/styles) + checks iframe src against domain blacklist
  (SSRF prevention). Frontend renders iframe directly — no lazy
  action needed.
- Backend: _process_embed_embeds + _sanitize_embed_html in
  lesson_service.py, applied to lesson_content, exercise,
  lesson_info, and slide loop. Graceful fallback if tinycss2
  missing (CSS unsanitized but tags/attrs still stripped).
- Tests: 9 pytest cases (Canva/YouTube HTML, script stripping,
  onclick stripping, blocked domain, non-https iframe, empty,
  unchanged, dangerous style).
- Frontend: remove renderEmbedEmbeds.ts + wire-up + .generic-embed
  CSS (URL-only approach from earlier iteration, superseded).
  Keep .embed-error CSS for error messages.
- Example: update test_slides.md with raw HTML Canva embed (slide)
  + YouTube embed (body).
- Deps: bleach>=6.0.0, tinycss2>=1.2.0 in requirements.txt.
- Docs: consolidate 4 plan files into docs/06-embed-content.md.

a2nr d6bb2073ac feat: add markdown link support for lesson prerequisites

- Supports both plain text and markdown link formats

a2nr cf3131bed3 chore: update velxio submodule — DeployProgress UI + SerialMonitor BLE toggle 2026-07-18 06:56:20 +07:00
a2nr a0fb1d80cd feat(velxio-deployer): unique device name + WiFi AP setup mode 
- Add device_name module: NVS-persisted custom name with MAC-suffix
  fallback (Velxio-XXXX) so every device is uniquely identifiable
  out-of-the-box in BLE pairing dialog
- Add wifi_ap module: first-boot SoftAP (Velxio-Setup-XXXX / velxio123)
  with embedded HTTP config portal at 192.168.4.1 for renaming
- main.c: enter AP setup mode when no custom name is set
- ble_service.c: use dynamic device name from device_name_get(),
  with adv-packet length guard
- led_button.c: BOOT button long-press (5s) factory reset (erase NVS)
- sdkconfig.defaults: enable WiFi stack + set NimBLE default name

Frontend deviceName display already committed in 01f68d3.
