pub fn add_note(
root: impl AsRef<Path>,
pin: &str,
body: &str,
now_unix: u32,
) -> Result<SanctuaryLane, String>Expand description
Append a note to the lane the PIN opens (real PIN → real lane; duress PIN → decoy only).
A decoy write also leaves a blind, sealed audit record on [DEFAULT_DECOY_BRANCH] that the
coercer cannot read; the real lane reviews it via review_decoy_activity. For git-like
per-session branches (one branch per duress unlock), use add_note_in_session.
