+# Goal: Merchant HUD And Location Capture
+
+Use Krypton Execution to execute `docs/goals/merchant-hud-and-location-capture/PLAN.md`.
+
+Core rules:
+- Treat `PLAN.md` as the source plan.
+- Preserve the existing recognition loop and use its `result` as the only live HUD truth.
+- Start with one Document Picture-in-Picture HUD; do not add a native wrapper unless its documented limitations block the real workflow.
+- Capture a merchant location only after an explicit user action and inline preview.
+- Store one bounded JPEG per shop visit and link item observations with the same `shopVisitId`.
+- Preserve auth, same-origin writes, catalog ownership and append-only observation batches.
+- Capture target-perspective evidence only with fresh manual-testing permission; otherwise report `implemented but visually unproven`.
