0.4.0

Library rewrite to bring it into alignment with probeinterface spec 0.3.x and to replace weakly-typed, mutation-heavy API with an immutable, strongly-typed design.

Breaking API changes

• Contact changed from readonly struct to sealed class; PosX/PosY changed from float to double; PosZ (double?) added for 3D probe support
• Contact.DeviceId and Contact.Index removed; channel mapping now lives exclusively on Probe.ChannelMap via ChannelWiring
• Contact.ContactId/ShankId are now nullable (string?)
• ContactAnnotations.cs removed; contact_annotations is now backed by an internal ContactAnnotationStore shared across all contacts on a probe
• Contact now has GetAnnotation, SetAnnotation, RemoveAnnotation for per-contact typed annotation access
• Probe parallel-array properties (ContactPositions, ContactPlaneAxes, ContactShapes, ContactShapeParams, DeviceChannelIndices, ContactIds, ShankIds) removed; all per-contact data is now accessed via Probe.Contacts
• Probe static factory helpers (DefaultContactShapes, DefaultCircleParams, etc.) removed
• ProbeAnnotations.Name renamed to ModelName to match JSON key "model_name"
• ProbeAnnotations.AdditionalProperties made private; typed access via GetAnnotation, SetAnnotation, RemoveAnnotation, AnnotationKeys
• ContactShapeParam shape properties changed from float? to double?; null shape params omitted from JSON (NullValueHandling.Ignore)
• ProbeGroup.Validate() now only throws; it no longer mutates data
• ProbeGroup.Normalize() removed; optional fields such as contact_plane_axes, device_channel_indices, contact_ids, and shank_ids are omitted from JSON when absent rather than defaulted
• ProbeGroup.ForceContactIdsToZeroIndexed() removed; contact IDs are labels, not indices, and forcing them corrupted valid data
• ProbeGroup.SetDefaultDeviceChannelIndicesIfMissing() removed; device_channel_indices is optional per the spec
• ProbeGroup.GetContactIds(), GetDeviceChannelIndices(), GetContacts() removed

New API Surface

• ChannelWiring static class: WireChannels, WireChannel, UnwireChannel, UnwireChannels with cross-probe uniqueness validation and rollback
• ProbeGroup.GetChannelMap() returns a global channel -> (probe, contact) map
• Probe.GetContactAnnotation, SetContactAnnotation, RemoveContactAnnotation for bulk parallel-array annotation access
• Probe.ContactAnnotationKeys enumerates defined annotation keys
• Probe.ChannelMap exposes the contact→channel mapping as a read-only dictionary; null means no channels assigned

Test Infrastructure

• Test project, generated using claude code, added tests covering round-trips against all probeinterface_library fixtures, schema validation, channel wiring, probe/contact annotation API, and spec validation edge cases
• probeinterface_library added as a git submodule for real-world round-trip and schema tests
• probe.json.schema bundled as an embedded resource for schema validation
• generate_fixtures.py added for regenerating synthetic test fixtures
