+# OpenBitdo Commenting Standard
+
+This project prefers concise, high-context comments.
+
+## Required Comment Zones
+- Command gating order and rationale (`bitdo_proto::session`).
+- Support-tier decisions and promotion boundaries (`candidate-readonly` vs `full`).
+- Unsafe/firmware blocking rules and brick-risk protections.
+- Retry/fallback behavior where multiple command paths exist.
+- State-machine transitions in TUI/app-core flows when transitions are non-obvious.
+
+## Avoid
+- Trivial comments that restate code syntax.
+- Comment blocks that drift from behavior and are not maintained.
+
+## Rule of Thumb
+If someone adding a new device could misread a policy or safety boundary, comment it.
