Signed limits

Windows Stamped works inside, signed per line beforehand. Stamped may narrow a window, never widen it; Stamped staff can never sign.

Settings

Every change here is illustrative in the demonstration plant. Nothing is saved.

About this setting

Illustrative
  • Signer is set per plant; plant head by default.
  • Narrowing is hatched inside the signed band.
  • Each signature creates a new version and a manifest entry.
  • Expired windows stop all writes on that parameter.
