Description: Summary Per the GPP Consent String Specification, the Canada (TcfCaV1) section encodes several fields as OptimizedRange / N-ArrayOfRanges, both of which use Fibonacci coding. They were using fixed-integer encoders. This corrects the encoding and keeps existing strings decodable. Fixes: VendorExpressConsent, VendorImpliedConsent, DisclosedVendors (OptimizedRange) — EncodableOptimizedFixedRange → EncodableOptimizedFibonacciRange. PubRestrictions (N-ArrayOfRanges(6,2), whose ids are an OptimizedRange) — new EncodableArrayOfOptimizedFibonacciRanges that reuses the existing Fibonacci OptimizedRange for each record's ids. The fixed variant is left untouched for TCF EU, which legitimately keeps the legacy encoding. (Base64 was already correct in this library — all TcfCaV1 segments use the compressed encoder. The traditional-vs-compressed issue only affected iabgpp-es.) Backwards compatibility The TcfCaV1 core and disclosed-vendors segments decode by trying the spec-compliant (Fibonacci) interpretation first and, if it doesn't round-trip back to the input bitstring, falling back to the legacy (fixed-range) interpretation. Strings produced by the previous encoder still decode correctly. Empty / bitfield-form data encodes identically either way, so only populated range-form data changes on the wire. Note: this is backwards compatible on read (new code reads old strings). The encoder now emits Fibonacci strings, so consumers still running the previous code will not read the new range-form output — it is a deliberate wire-format correction for the affected fields. Test plan mvn test — full suite passes (368 tests) Per-field encode/decode + round-trip tests (sparse IDs exercise the Fibonacci range path) Backwards-compat decode tests using real pre-fix strings (vendors, PubRestrictions, plus a full real-world legacy string) 🤖 Generated with Claude Code
