The shortest responsible path
- Identify: confirm the exact model and physical control-board lane.
- Choose: use only the route authorized for that lane; no route means no flashing.
- Recover: verify the stop condition and restoration path before any write.

No verified prebuilt file is listed for this exact model in registry 2026-09-01.5. Do not substitute another model’s file.
Mining, installation, and recovery boundaries
- Mining
- The source records exact topology and package-format evidence, but the installed runtime remains management-only and no accepted-share proof is claimed.
- Installation
- The am3-s21xp install row has no implemented update mechanism, denies installation and authorizes no persistent update.
- Recovery
- No external-media, installation-write or recovery route is published.
Proof, gap, and limitations
Proof: Exact BM1370/Amlogic topology and package-format source evidence.
Open gap: Prove safe runtime ownership, accepted shares, a verified artifact and reversible install/recovery.
- S21 XP must not inherit the S21 or S21 Pro serial topology.
- A package format in source is not a verified public binary.
- Persistent update is not authorized.
