Two fixes:
1. db_layer.update_task_status: map invalid failure_stage values (e.g.
'process' from Edge) to 'callback' before DB write, preventing
MariaDB ENUM DataError (1265 "Data truncated")
2. dispatcher._poll_once: wrap each task dispatch in try/except so one
task's failure doesn't skip remaining tasks in the batch
Root cause: Edge returns failure_stage='process' but DB ENUM only allows
download/extract/vlm_visual/vlm_fusion/callback. The DataError crashed
_poll_once(), causing all subsequent PENDING tasks to be skipped.
Rationale: Oracle cannot reach NAS (Tailscale userspace mode on NAS, no TUN),
the old pull+webhook design requires Edge to download video from NAS and
callback to NAS - both blocked. New design is one-way NAS -> Oracle:
- FAM-Edge: new POST /api/edge/video/push endpoint accepts multipart video
upload, reuses existing OpenCV scene-change keyframe selection, analyzes
synchronously and returns the result payload directly in the HTTP response
(no webhook callback). Old /api/edge/video/analyze kept for compatibility.
- FAM-Edge: VideoPreprocessor.save_upload() saves the uploaded file
- FAM-Edge: AIOrchestrator.process_push_task() runs the full pipeline
(health check -> extract -> select -> compress -> VLM -> fusion) and
returns callback-style payload dict
- FAM-Core: Dispatcher rewritten to push mode - reads local video file,
uploads with task metadata (camera_name, event_start_time from file mtime,
known_members_context), applies the result to DB via shared
event_receiver.apply_success_event()
- FAM-Core: event_receiver success logic extracted into reusable
apply_success_event() (used by both webhook route and dispatcher)
- config: edge_url -> /api/edge/video/push, push_timeout 1800s, gunicorn
Edge timeout raised to 1800s for long synchronous analysis
- name_member(): replace MySQL-only JSON_REPLACE/JSON_CONTAINS with wildcard
JSON paths (unsupported in MariaDB 10.11) with Python-side JSON parsing
- FAM-Core venv rebuilt with Python 3.10.20 on NAS
- All API endpoints tested: health, status, member list, unnamed, naming
- POST /api/member/name: 人物A successfully named to 张三
- PROGRESS.md updated with full test results and task completion
