Fingerprint Policy

fingerprint controls the background signal lane for page fingerprint and health gathering.

fingerprint:
  signal_lane: true
  backpressure: defer
  max_queue: 256

Leaving fingerprint unset means no fingerprint lane is created.

Fields

Field	Type	Default	Description
signal_lane	boolean	true	Enable the off-path signal lane when the sub-policy is attached.
backpressure	enum	defer	defer keeps work for later. drop bounds memory by dropping work.
max_queue	integer	256	Maximum queued signal jobs.

Fingerprint gathering is separate from trust decisions. The trust gate lives in top-level trust_tier and atom/source policy.
