Update validate_tactile_metadata to reject metadata unless

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Reject a known binding profile when its version_major is not 1.
validate_tactile_binding_profile checks the profile ID and then parses payload as the v1 TactileBindingProfile layout. It never reads profile.version_major(). The schema comment says that version_major controls compatibility. A profile with a known ID and version_major = 2 (or 0) is therefore parsed and accepted as v1. The validator reports the profile as understood, but the payload semantics can differ. A REQUIRED profile must fail closed in this case. Check the major version only. Accept any version_minor, because minor changes are additive.
validate_tactile_metadata (Line 172) has the same gap: it accepts any non-zero schema_version, so a v2 metadata buffer passes as v1.
Proposed fix
inline void validate_tactile_binding_profile(const SemanticProfile& profile, size_t node_count)
{
+ if (profile.version_major() != 1)
+ {
+ throw std::invalid_argument("unsupported tactile binding profile major version");
+ }
const auto* payload = profile.payload();At Line 172:
- if (metadata.schema_version() == 0)
+ if (metadata.schema_version() != 1)
{
- throw std::invalid_argument("schema_version must be positive");
+ throw std::invalid_argument("unsupported tactile schema_version");
}Based on learnings: "readers/parsers should reject inputs with a different major version (breaking changes), but accept any minor version difference within the same major."

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Summary
SemanticProfileenvelope with versioning, required/optional handling, opaque typed payloads, and content-addressed external resourcesTactileTrackerexamples/tactile; the printer reports metadata and the first/last taxel values once per second through the standard DeviceIO interfaceProtocol boundary
The per-frame schema contains only tactile values and per-taxel status. Immutable geometry and measurement semantics use tracker metadata. Skeleton and runtime associations use typed profiles, so unknown extensions remain forwardable and IsaacCapture-specific session identifiers do not enter the portable tactile core.
The taxel frame is right-handed: +Z is the outward normal, +X is the tangent, and +Y is
N x T.Validation
