Allow IPA agents to golf source and scene voices

   - IPA training scoring contract is documented. Reports must keep `gesture_score`, `clean_vocal_score`, and `full_parity_score` separate. Gesture score measures descriptor-to-surface coverage, motion direction, spline contour/timing, primitive timeline consequences, and optional external articulation landmarks. Full parity patches may use FM/AM/modulators/envelopes/filters, auxiliary animated voices, and recording-condition helpers, but those helpers cannot count as articulation evidence unless gesture and clean-vocal scores move coherently.
   - `IpaGestureExperiment.WriteRound` is the first frozen batch harness for IPA hypothesis work. It writes `manifest.yaml`, candidate `.aqua` scripts, primitive `ProbeTimelineReport` CSVs, gesture-layer `metrics.csv`, and per-candidate `evidence.jsonl` under a caller-provided artifact root. `IpaGestureExperiment.AnalyzeRound` writes `analysis/metric-summary.csv`, `analysis/candidate-clusters.csv`, and `analysis/science-brief.md` for the science-worker handoff. This harness owns frozen descriptor/spline/primitive evidence only; clean vocal identity, full spectrogram parity, optimizer checkpoints, and worker orchestration stay downstream. Focused verification: `PatchScriptTests` pass 93/93.
   - `IpaTrialOrchestrator.RunAsync` is the first local render/scoring worker for IPA trials. It generates candidate patches through `IpaGestureExperiment`, renders them through Faust, compares against local PT fixture references with `AudioAnalyzer`, writes WAV/report artifacts, and stores typed `IpaTrialResult` records in `ipa-trial-results.cc`. The five-seed trial run at `tests/AquaSynth.Dsl.Tests/bin/Debug/net10.0/artifacts/parity/ipa-trials/20260529T214127955/five-seed-trials` showed voiced vowels/nasals became audible only after primitive `SourcePort` lowering gained a true oscillatory voiced carrier; sibilants are pressure, plosives remain weak. Verification: opt-in IPA trial test passed, and focused `PatchScriptTests|IpaTrialResultsRoundTripThroughCultCache` pass 94/94.
-  - External IPA exploration now has a worker/tool boundary. `tools/IpaTrialWorker` owns `seed`, `score`, `search`, `show`, and audit-only `dump` commands over the typed `.cc` trial-result store; `score` renders external Codex-authored `.aqua` candidates through `IpaTrialOrchestrator.RunCandidateScriptsAsync`, while `search` is the semantic retrieval organ for hypothesis agents. `IpaTrialResult` records now embed extracted primitive timeline facts from `ProbeTimelineReport` for contact closure/reservoir/release, source load/flow, branch admittance/exchanged flow, radiation boundary/output, path area/delay/energy, and passivity; `search`, `show`, `dump`, and summary CSV output surface release/radiation/passivity witnesses directly from the `.cc` record. `search` follows VoidBot's Qdrant shape: `.cc` records plus timeline facts and referenced local artifacts become evidence chunks, local Ollama `qwen3-embedding:0.6b` produces 1024-dim vectors, Qdrant collection `aquasynth_ipa_trial_results` stores stable SHA-256 UUID points with trial/candidate payload metadata, and the report surfaces vector scores, excerpts, tags, metric facts, timeline facts, contrast candidates, `class_focus`, per-hit `class_match`, and `show` commands. Qdrant is a derived index; CultCache remains truth, and lexical/metric search is fallback when the vector stack is unavailable. Retrieval tuning added phonetic class-affinity scoring and candidate-specific mixed-lane ownership so `mix-p` can support stop seams without every mixed candidate matching stop evidence. `tools/run-ipa-trial-loop.ps1` orchestrates external `codex exec` hypothesis/evaluator workers around that store. The active trial shape is five target sets of five phoneme lanes each: vowels, nasals/approximants, fricatives, stops, and mixed generalization. Candidate names are exactly `<targetId>__<family>__<hypothesis-name>.aqua`, with lowercase kebab-case family ids. Three dry external Codex smoke passes refined hypothesizer/evaluator prompts into exact 25-lane output, retrieval receipts, claim audits, evidence-quality ledgers/verdicts, and fail-closed evaluator compliance. A later five-pass prompt optimization showed the best science comes from fixed receipt packets plus constrained reasoning; production prompts now require contrast pairs, `show` metric values, primitive timeline facts/excerpts or explicit `missing`, class-consistent reference matrices, `X owns Y so Z remains true` owner sentences, at least five micro-sweep perturbations before a seam is actionable, and a novelty gate rejecting loudness/dressing-only families as loss-landscape novelty. Verification: focused builds/tests pass, old-store show compatibility passes, and a fresh one-candidate smoke under `artifacts/parity/ipa-timeline-fact-smoke/20260531T233217641` proves release/radiation/passivity facts persist and retrieve through Qdrant/Ollama.

Source-edit-enabled rounds now allow agents to golf DSL syntax, parser/model records, Faust lowering, worker evidence surfaces, and tests when evidence points at a repeated owner failure; agents must write `source-change-plan.md`, and the loop runs a focused build before scoring. Candidate reports must include a `Scene Voice Model` naming primary-articulatory, tract-noise, release/transient, background-room, and recording-condition voices, with general AquaSynth synth primitives allowed for helper scene voices but not accepted as articulation evidence unless lower-layer witnesses move.

   - 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.
