# Agent Notes
## Media importer lineage
AutoNAS derives its unattended camera import behavior from:
```text
/Users/bogdan/Documents/Workspaces/Bogdan/Media Importer/media-importer.sh
```
Before changing `scripts/autonas-media-importer.sh`, read the upstream note:
```text
/Users/bogdan/Documents/Workspaces/Bogdan/Media Importer/AGENTS.md
```
The Raspberry Pi importer/wrapper direction from the old Media Importer repo is a dead end and must not be used as a reference design unless that direction is explicitly reopened.
## Unattended safety rules
AutoNAS runs from udev/systemd and is therefore unattended by default. Changes must preserve the upstream data-loss protections:
- no overwrite of existing destination files;
- destination conflicts resolved before copy/move;
- planned destination paths reserved during one run;
- move mode implemented as copy, verify, then delete source;
- source deletion only after destination verification succeeds;
- destination temp files cleaned on copy/verify failures;
- `VERIFY_MODE=size` default with `strict` available;
- GoPro timestamp changes require regression testing against real MP4/THM/LRV cases.
If any of these protections are missing, do not recommend AutoNAS unattended import.
## Required validation
For importer changes, compare behavior with upstream `media-importer.sh` and, when possible, run upstream tests:
```bash
cd "/Users/bogdan/Documents/Workspaces/Bogdan/Media Importer"
./test_runner.sh timestamp-collision
./test_runner.sh verify-mode
./test_runner.sh dest-in-source
./test_runner.sh gopro-sidecar-sync
./test_runner.sh gopro-no-sidecar-reimport
```
If these cannot be run, mark the AutoNAS importer as partially validated only.
