`AudioSignature` is the DSP — band table, periodic Hann, radix-2 FFT, band-mean peak, energy class, packing — and `AudioSignatureService` the decode, running the FFmpeg binary `IMediaEncoder.EncoderPath` names. The plugin gained no dependency. The server specification's prose does not determine a byte stream, so the parameters it leaves open are pinned by the fixture shared with the extraction repo and restated at the top of `AudioSignature`: double throughout, whole frames only, periodic Hann, unnormalised FFT, band mean rather than sum, argmax ties to the lowest index. `fixtures/audio/` holds the extraction repo's three files byte-identically and the computed signature equals the recorded vector exactly. The binding check regenerates the fixture PCM from `make_fixture.py`'s arithmetic and verifies it against the recorded decode checksums, so it runs on a host with no codec at all and a decode divergence stays distinguishable from a DSP one; the two tests that drive real FFmpeg self-skip without a binary. The workflow named "Test Plugin" until now only compiled one. A test that is built and never run is not evidence, and a golden vector shared across two repos exists precisely so CI fails when they drift. TRACES: JR-042, JR-043 | SR-003
