Sample Implementation Sketches

These are not production files. They are indexed sketches for future cuts, written to make implementation options concrete without sneaking half-built machinery into the app.

Files

  • StreamingChirpBinDecoderSketch.cs: C# state model for an incremental chirp-bin decoder that avoids full-window rescans.
  • Avx2DechirpGoertzelSketch.cpp: AVX2/FMA-shaped CPU scoring kernel sketch.
  • BatchedChirpScoreAbiSketch.h: native scoring ABI shape for batching candidate/bin work across the managed/native boundary.
  • ChirpBinScore.compute.hlsl: D3D12 compute shader shape for batched candidate/bin scoring.
  • FarrowFractionalDelaySketch.cpp: native fractional delay actuator sketch.
  • SpscAudioBlockRingSketch.cpp: native single-producer/single-consumer audio block ring sketch for capture worker handoff.
  • CalibrationWeightedChirpLikelihoodSketch.cs: shows how response/confusion/ phase/group-delay calibration should shape symbol likelihood before codebook path selection.
  • SroPllAsrcControllerSketch.cpp: control-rate delay/SRO loop for driving an ASRC or fractional-delay actuator.
  • GaussianSplatClaimUpdate.compute.hlsl: minimal Fensalir compute shape for turning synchronized visual observations into live splat claims.
  • AquariumGpuSensorFrameBridgeSketch.cs: contract sketch for lowering runtime video observations into Fensalir GPU sensor frames.
  • AcousticConstraintLoweringSketch.cs: contract sketch for lowering decoded chirp/passive anchors into Fensalir acoustic constraints.
  • TemporalEvidenceCandidateSketch.cs: candidate lowering sketch that keeps stable track ownership in Fensalir.
  • SrpPhatGridSketch.cpp: minimal TDOA/SRP-PHAT-style grid scoring proof for a synchronized mic constellation.

Rule

Promote one of these only after a benchmark or integration test proves it owns a real invariant. Sample code is a microscope, not a new wall in the house.
