- fc_writer.h/fc_writer.c: new framecache slot writer module
- Registers slot via POST /slots to framecache HTTP API on signal lock
- Opens shm file returned by API (O_RDWR + mmap MAP_SHARED)
- fc_writer_write(): atomic write_cursor advance + sem_post per frame
- fc_writer_close(): DELETE /slots/:id + munmap + sem_close
- HTTP calls via raw POSIX sockets (no libcurl dependency)
- Parses host:port from FC_URL env var or --fc-url arg
- main.c changes:
- PortState gains slot_id, fc_url, fc_writer fields
- --fc-url CLI arg + FC_URL env var (default http://localhost:7435)
- On signal lock: fc_writer_open() before thread launch;
falls back to FIFO if framecache unreachable (fc_writer == NULL)
- video_thread: shm path primary (fc_writer != NULL),
FIFO path fallback (fc_writer == NULL or LEGACY_FIFO=1)
- Format JSON now includes slot_id field for node-agent consumption
- Cleanup: fc_writer_close() before VHD_CloseBoardHandle
- CMakeLists.txt:
- Add fc_writer.c to build
- Link rt (shm_open, sem_open)
- LEGACY_FIFO option (OFF by default) for nodes without framecache
Audio thread unchanged — audio stays in FIFO (shm audio is roadmap).
- services/framecache/: new standalone container
- slot.h/slot.c: shm ring buffer (120 frames, FC_MAGIC header, atomic
write_cursor, POSIX semaphore per slot)
- registry.h/registry.c: in-memory slot registry + /dev/shm/framecache/
registry.json persistence
- framecache.c: HTTP API server (libmicrohttpd, port 7435)
POST /slots, GET /slots, GET /slots/:id, DELETE /slots/:id, GET /health
- fc_client.h/fc_client.c: consumer library — fc_consumer_open/read/close
with per-consumer cursor, timeout via sem_timedwait, automatic skip+count
when consumer falls behind writer by > ring_depth frames
- fc_test_consumer.c: dev utility to attach to any slot and print fps/stats
- CMakeLists.txt: framecache server + fc_client static lib + test consumer
- Dockerfile: builder + slim runtime stages
- docker-compose.worker.yml: add framecache service (profile: capture,
ipc: host, shm_size from FC_SHM_SIZE_GB env var, healthcheck)
- .env.example: document FC_SHM_SIZE_GB with per-node guidance
fs.writeFile/fs.readFile/fs.stat are callback-based and don't return
Promises in the UXP sandbox. await on them resolves immediately, causing
race conditions where files aren't written before import.
Added _writeFile/_readFile/_stat wrappers that use fs.promises when
available and fall back to manual Promise wrapping otherwise.
Also bumped version to 2.2.3 to match web-ui data.jsx.
- Revert accent from Flame Blue #1025A1 to electric amber #E8821C
- Restore all rgba accent values to orange spectrum
- Revert avatar to bg-3 background + accent text (was blue bg + white)
- Revert primary button text to dark #0a0c10 (was white on blue)
- Restore centered hero with logo pulse + 'Let's Create' kicker
- Restore single-grid tile layout (all tiles in one launcher-grid)
- Restore settings as separate centered row below main grid
- Restore centered footer + large wordmark with amber glow

Relying on the SDK default for VHD_CORE_SP_BUFFER_PACKING caused the board
to deliver raw slot buffers whose byte size did not match the width*height*2
contract declared to ffmpeg (pix_fmt=uyvy422). ffmpeg consumed frames at the
wrong stride, causing every frame to shift progressively, rolling and
shearing the picture ("bounces and bends").
Fix: explicitly set VHD_BUFPACK_VIDEO_YUV422_8 on the video stream before
StartStream so the board always delivers tightly-packed 8-bit UYVY.
Safety net: video thread now asserts sz==width*height*2 and skips+warns on
any mismatch so a future packing divergence is immediately visible in logs
rather than silently corrupting video.

The live-thumbnail and manual /start,/stop sidecar->mam-api calls hit the CSRF
guard (403 missing X-Requested-With). Match the working pattern in index.js:
send Authorization: Bearer $MAM_API_TOKEN (= CAPTURE_TOKEN, injected by
recorders.js), which is CSRF-exempt. Falls back to the UI header only when no
token is set (dev). Fixes [livethumb] failed ... 403 — posters now persist.

A native deltacast-bridge build leaves services/capture/deltacast-bridge/build/
with a CMakeCache.txt pinned to the host path. When copied into the Docker
build context it conflicts with the in-image cmake step and fails the capture
image build. Exclude build artifacts from the context.
