Correct primitive source and radiation timeline laws

   - Primitive path telemetry now reports `incoming_wave`, `outgoing_wave`, `energy_in`, `energy_out`, and `passivity_ratio` in both Faust debug probes and `ProbeTimelineReport`; contact telemetry includes resistance. `PrimitiveReferenceReport.ComparePinkTrombone` compares static primitive area sections, length, reflection count, delay estimate, branch admittance, contact state, and radiation fields against local PT/SndKit fixture controls without adding a native reference dependency. Next pressure is per-block comparison against PT/SndKit internals, not static control matching alone.
   - `PinkTromboneReferenceRenderer.RenderTimeline` now exposes PT internal oral/nasal path, branch, contact, and radiation samples from the renderer's own diameter/wave/reflection/transient arrays. `PrimitiveReferenceReport.ComparePinkTromboneTimeline` role-normalizes Aqua primitive samples against PT timeline samples for path/branch/contact/radiation signals. This is the first local reference-internal comparison surface for the primitive rebuild; next pressure is fixture-suite artifact reporting and then tightening laws where the timeline drift points.
   - `PinkTrombonePrimitiveTimelineComparisonWritesArtifacts` writes per-fixture Aqua primitive timelines, PT internal timelines, comparison CSVs, and a summary under `artifacts/parity/primitive-vocal-timeline/<timestamp>`. This makes primitive drift inspectable across the PT fixture suite without native Faust or external VTL/ArtiSynth dependencies. Use these artifacts to choose the next physical-law correction.
+  - First comparison-driven primitive law correction: `SourcePort` owns `FlowScale` (default `.02`) so pressure/tension/opening no longer emit hidden unit-scale waves; `RadiationLoad.Reflection` owns reflection directly and aperture no longer rewrites that coefficient; `ProbeTimelineReport` radiation flow now uses path outgoing wave like Faust instead of reporting `aperture / impedance`. Artifact `artifacts/parity/primitive-vocal-timeline/20260529T155613895` drops fixture-suite mean absolute timeline error from roughly `1.2-1.3` to `0.15-0.27`. Remaining large drift is branch/contact dynamics, which needs an owner decision about gesture slew versus primitive-local smoothing.
   - TurbulenceJet now includes a release-timed burst-noise component in addition to the deterministic pressure pulse, but a stronger trial barely moved papa; the source is not the main remaining articulation bottleneck. Graph radiation now mixes 30% raw boundary flow with 70% high-passed flow after local admittance weighting, down from the over-bright 15/85 blend. Latest radiation/source artifact under `artifacts/parity/pink-trombone-utterance-logmel/20260527T174236049`: mama/papa/thrombosis cosine 0.6578/0.7692/0.5585, rmsRatio 3.0006/2.6153/2.3488, articulation 0.1437/0.1173/0.1191. Static `closure-release` under `artifacts/parity/pink-trombone-logmel/20260527T174139661` has rmsRatio 0.9900 and speechBandRatio 0.0842. This is still not speaking; next pressure is true tract resonance/passive scattering and pressure storage, not more burst gain.
   - Same-path two-port area discontinuities now emit `graph_area_energy_in_*` and `graph_area_energy_out_*` probes alongside the three-port branch `graph_connection_energy_*` probes. Use these to inspect passivity and formant-body failures at the scatter sites rather than judging only final output loudness.
   - `FaustExportOptions.DebugProbeUi` wraps graph probe signals in Faust `vbargraph` UI controls under `/debug/...` without changing audio output arity. Native streaming Faust patches now separate writable controls from read-only probe zones and can read/snapshot probe values after `ProcessBlock`; use this for acoustic graph passivity/radiation inspection, leave it off for normal parity renders.
