nx_fluid_seal.nx

nx_fluid_seal.nx -- fluid/seal-integrity kernel (#4 of 4 -- COMPLETES the physics-kernel set). Independent leak detection for plumbing, brake fluid, coolant, hydraulics, refrigerant, tires -- anything that should hold pressure or stay sealed. Two universal independent signals, integer/no-float: - PRESSURE-DECAY TEST: isolate the system, watch pressure over time. A healthy seal holds; a failing seal DECAYS. Decay rate -> severity, on the seepage -> leak -> rapid-loss progression (catch it BEFORE catastrophe). - FLOW-WHILE-ISOLATED: any flow when the system is isolated = a leak path (the hidden slab-leak / continuous-drip a homeowner never sees). THE EXCEED: most fluid systems have NO independent leak detection -- you learn of a leak from water damage / low fluid / brake failure. This quantifies seal integrity early and continuously, vendor-independent. NEVER-BRICK (#26): reads pressure/flow, emits a verdict; writes nothing, actuates no valve. Read-only by construction. genealogy_id: project-maintenance-platform-sclass-2026-06-23 (kernel #4 -- set complete) license_tier: ORIGINAL nx_capability_claims: needs: [pointer_arithmetic] provides: [pressure_decay_leak_test, flow_while_isolated_leak, seal_integrity_verdict, early_progression_detect] safety: [no_floating_point, no_syscall, bounded_iteration, read_only_no_device_write, no_firmware_write_by_construction, sealed_enum_verdict] verdict: [sealed_enum_fluid, no_silent_failure] license: ORIGINAL kind: maintenance_runtime_primitive
