ICE-77 / CREDENTIAL GEOMETRY
IDENTITY / DRIFT / QUARANTINE
A credential becomes hostile when its shape cannot exist.
Black ICE Credential Geometry models impossible identity paths, signature drift, privilege curvature, toolchain heat, and false-positive risk before ICE-77 is allowed to mirror, trap, burn, or quarantine a netrunner session.
Evidence retention window for ambiguous credentials before burn authority can be escalated.
Minimum independent custody nodes required before credential geometry can become board evidence.
Geometry Stack
The runtime scores the shape of authority before it scores the attacker.
Credential Geometry treats access as a moving vector: role, device, behavior, route, cadence, and toolchain must resolve to one plausible corporate body before ICE responds.
AVF-01
Authority Vector Field
Compares role, session origin, biometric cadence, device lineage, and regional clearance against expected movement geometry.
SDM-02
Signature Drift Membrane
Measures packet timing, command grammar, memory write rhythm, and spoof pressure before the credential reaches value.
FPQ-03
False-Positive Quarantine
Holds ambiguous sessions in mirrored compute so human operators can distinguish compromised staff from hostile netrunners.
CRL-04
Credential Receipt Ledger
Binds the credential shape, operator decision, trap class, proportionality rule, and witness quorum into admissible evidence.
Geometry Envelope
A trap cannot fire until the identity problem has a lawful shape.
Credential Geometry requires a protected surface, credential class, drift threshold, response limit, and false-positive hold before an ICE mesh can move beyond observation.
Protected surfaceSovereign net, custody API, executive room, industrial command, or neural vault corridor
Credential classStaff identity, machine relay, privileged toolchain, contractor path, construct interface, or emergency override
Drift thresholdImpossible region hop, cadence mismatch, privilege curvature, memory rhythm, or route heat anomaly
Response limitObserve, mirror, soft trap, hard trap, quarantine, manual lock captain, or board hold
Excluded useUnwitnessed burn, employee dragnet, punitive credential scoring, uncontrolled Blackwall contact
Counterintrusion Routing
Credential Geometry routes Black ICE decisions through mesh specification, runtime doctrine, response protocol, Blackwall containment, and board evidence.
The geometry dossier decides whether access is possible. The mesh decides how to trap it. The response protocol decides when operators may burn the path.
