nx_maint_ingest.nx

nx_maint_ingest.nx -- the HARDWARE-facing ingest rung (R1) of the maintenance platform. Turns a raw sensor reading from ANY source into the normalized, typed sample the physics kernels consume, and routes each sensor KIND to its kernel. This is the rung the 5 kernels were floating above -- it closes the hardware -> kernel path (R0 driver -> R1 ingest -> R2 kernel). Operator (2026-06-23): build the platform "from the hardware rung up, each rung." Sensing doctrine (operator-chosen): sovereign-DIY PREFERRED, support any source (Emporia/Sense/OBD/manual) vendor-agnostically; UNKNOWN is first-class (recorded for later, never dropped) -- the IoT-brain doctrine. NO-FLOAT: normalization is a DATA-DRIVEN affine transform (scale_num/scale_den + offset live in the source config #11, not hardcoded per-vendor guesses -- honest: we don't invent vendor wire formats; the per-vendor DRIVER (R0) supplies the raw value + its scale). NEVER-BRICK (#26): reads a value, normalizes, routes; writes nothing, commands no sensor. Read-only by construction. genealogy_id: project-maintenance-platform-sclass-2026-06-23 (R1 hardware-ingest rung) license_tier: ORIGINAL nx_capability_claims: needs: [pointer_arithmetic] provides: [vendor_agnostic_sensor_ingest, kind_to_kernel_routing, data_driven_normalize, unknown_sensor_first_class] safety: [no_floating_point, no_syscall, bounded_iteration, read_only_no_device_write, no_firmware_write_by_construction, sealed_enum] verdict: [sealed_enum, no_silent_failure, unknown_recorded_not_dropped] license: ORIGINAL kind: maintenance_runtime_primitive
