Migration dry-run sample. Imported from Linear to validate Gitea issue formatting, labels, and comments before the full migration.

Imported from Linear: CUB-230
Linear URL: https://linear.app/cubecraft-creations/issue/CUB-230/esp32-offline-status-buffering-and-replay-on-reconnect

Description

When venue Wi-Fi drops, ESP32 buffers status locally (SPIFFS) and replays on reconnect. Define: max buffer, FIFO eviction, MQTT replay protocol, hub-side dedup via (camera_id, recorded_at) uniqueness.

Imported Linear comment from CubeCraft Creations at 2026-05-23T12:29:49.397Z on CUB-230:

Hub dedup work split to new sub-issue CUB-239 (created as CUB-239 instead of CUB-240 — corrected from earlier comment).

Evidence summary for firmware (ESP32) portion:

  • Branch: agent/pip/CUB-230-offline-buffer-replay
  • Commit: 1efd48e
  • PR: #10

Moving to In Review — firmware portion is complete with evidence. Hub dedup tracked in CUB-239.

Pip Dispatch Result — Partial

Firmware (ESP32) — COMPLETE:

  • SPIFFS buffer: /status_buffer.json with JSON array of {recorded_at, status} entries
  • FIFO eviction: removes oldest entry when max_buffer_entries exceeded (default 100)
  • MQTT replay: replays buffered entries on reconnect, clears buffer after replay
  • Configurable via esp32-config.json: max_buffer_entries, buffer_file

Evidence:

  • Branch: agent/pip/CUB-230-offline-buffer-replay
  • Commit: 1efd48e
  • PR: #10
  • Firmware file: firmware/src/esp32-mqtt-bridge.cpp

⚠️ Issues:

  1. .pio/build/ artifacts committed — need to remove build outputs from the branch
  2. Hub-side dedup NOT implemented — the (camera_id, recorded_at) uniqueness check in the Go backend was not done; tracking as CUB-240

Next: Hub dedup work split to new sub-issue CUB-240, will dispatch to Dex.
