sealing is the block height at which a signal is finalized — when the zheng proof is produced and the signal becomes irrevocable

sealing is the second timestamp of a two-part duration. together with inception, it defines the span of a signal:

span = sealing_height − inception_height

at sealing, the neuron produces a zheng proof covering all cyberlinks, the impulse, and conviction box movements. this proof anchors the entire computation to the sealing height and the current BBG root

before sealing is assigned, the declared action exists as an intent. the act of sealing transforms the intent into a completed signal

an intent that never receives a sealing height becomes abandoned — on record at its inception height, permanently unfinished
