# Brief 3: Layer-0 identify route + client orchestration
|
||
|
|
|
||
|
|
## Goal
|
||
|
|
|
||
|
|
kNN visual match before L1/L2; log `scan_attempts.layer = 0`.
|
||
|
|
|
||
|
|
## Acceptance criteria
|
||
|
|
|
||
|
|
- [ ] `POST /api/scan/identify-by-image` — auth + `checkScanRateLimit` + embed + kNN
|
||
|
|
- [ ] `identifyTrackedCardCapture` order: L0 → L1 → L2
|
||
|
|
- [ ] Gallery path runs L0 → L1 → L2
|
||
|
|
- [ ] Skip auto Gemini refine when disambiguation from L0 (same as L1)
|
||
|
|
- [ ] Thresholds: match 0.82, disambiguation 0.58
