Connect configurable stateless pressure candidates to the existing accepted SimulationSession owner. The host supplies actual post-viscosity RHS, shortened dt/interval, accepted prior pressure and composition prefix, while the existing pressure/velocity/volume/final-publication gates retain authority. Compose the existing sealed full-liquid Newtonian stage with that same pressure gate; no new numerical kernel or pressure-history volume is added.

Publish a typed owned binding/context receipt only with a completely accepted interval. Invalid bounded identity metadata rejects before provider callbacks. Changing viscosity or clearing history forces native reseeding. Pressure-stage rejection retains same-request native fallback; later whole-interval failure preserves fields, receipt, history and quota. prediction_called attests host method entry, not external IPC. Immutable constructor configuration and owner-captured accepted interval starts support exact cold interpretation without reconstructing start by subtraction.

The hosted browser gate exposed a real regression: the portable context imported sha2 while Cargo restricted that existing dependency to native targets. Move the same exact sha2=0.10.9 entry to common dependencies, with unchanged locks, features and versions. Independent manifest review approves this fix; the unfixed wasm32 compile reproduced E0432 and the fixed actual wasm32 release build passed.

This head retains current main8bf7 and reviewed isolated CI setup50732f5 without changing the105 numerical source pins. The reviewed exact CI-budget-guard correction on112ad8564c is also retained; independent review preserves every workload/matrix/status/budget guard. No older whole-Git evidence is transferred.

Validation on clean source ec46127e3295bf426a47ca13f855798a7b546a2c, tree 2cf7480f30549eaf70b31346e2a2e56924b73b16:

• Independent GPT-6.1 Sol numerical/API, constructor, interval and portable dependency reviews are committed with exact source pins.
• Complete conservative admission:105 paths; only the portable manifest pin changes from preceding numerical source,104 unchanged. All18 fresh native/rational qualification commands and26 real-packet contracts normally plus26 optimized passed. Lean checking was not run.
• All58 core/API contracts passed, zero ignored, including actual existing modal checkpoint Session and transport consumers. Strict affected desktop/test Clippy and both native builds passed with the full declared revision.
• A fresh actual browser packet built successfully. Release browser contracts passed six cycle and three flow tests. Browser-builder contracts passed12 normal/12 optimized; flow contracts13/13. Timestep suites each reported14 entries with three explicit actual-rendered-edition skips (11 executed), preserving the separate hosted full-edition gate. These skips are not reported as executed browser checks.
• Receipts: /tmp/rheon-session-final-qualified, /tmp/rheon-session-final-packet, /tmp/rheon-session-final-browser; external logs use /tmp/rheon-session-final-*. Complete receipt SHA256 55b59c0f22fd39c6a0ccb59ba1fcb58c83f1a03be83cc837449eeb7bea0c48f9. Exact pushed-head hosted workflows remain mandatory before readiness or merge.

This numerical/API slice does not connect an external CPU package, persist typed accepted reports or complete saved accepted workflows. Those are separately owned #103/#104/#105 and follow-on components. Native analytical fixtures and the different existing modal checkpoint consumers do not establish missing measured aa82 bundle parity, learned accuracy, GUI behavior or hard shutdown bounds. Base includes validated #99/#101. Lead owns serial integration and all merges; keep draft until all gates pass.

Merged as 76142a80c780c219ffc1dfee12db36e55c425b81 at2026-10-16T03:08:39Z after exact-head20checks/12workflows and fresh-main merge-tree equality passed. This closes the bounded core/API acceptance unit; producer/consumer and measured A1 keep their separate dispositions.

M2–M3 worker resumed under parent instruction for a lead-coordinated disjoint accepted-provider persistence/acceptance allocation. I see PR102 b41e9053 owns configured accepted Session numerical/API composition, and PR101 owns CI consumer selectors. I will not edit those sources or repeat completed PR99 review.

Proposed recording scope for your serial allocation: new src/recording/provider.rs codec/contracts + new tests/recording_provider_contract.rs / cold producer-reader example, minimal src/recording.rs registration only if assigned; persist actual accepted owned binding/context/report/history metadata and exact accepted pressure/carrier data via existing StepRecorder/RecordingReader, preservingv1/schema2 diagnostic interpretation. No external CPU package, competing store/supervisor, fake accepted native stamp or measuredaa82claim. Need your current accepted-capture ownership/API decision and exact allowed paths/base before shared source edits. I am reading your typed receipt and existing capture seams now so I can deliver a concrete minimal proposal/test allocation without collision. Parent retains all merge ownership through lead.

[MrScripty]

Concrete capture findings from exactb41e9053 read-only design review:

1. SessionSnapshot.state() exposes the actual accepted pressure/carrier/fraction arrays, so provider capture can avoid carrier_publication entirely. A distinct typed Session profile within existing StepRecorder v1 is needed; native RecordedCarrier requires exact4/5field inventory/native solver role and must not be relabeled.
2. Snapshot has no actual config/implementation getter. A recording helper cannot derive an actual frozen SimulationSpec from it; either allocate a narrow numerical-owner snapshot getter, or explicitly keep a caller-declared frozen recipe with constructor/runner association. I will not quietly infer settings from Debug text.
3. Valid accepted provider reports may contain NONFINITE rejected-candidate diagnostics: ProviderWorkspace records candidate PressureReport before QualityGate rejection, then native fallback can succeed. Codec must preserve those raw diagnostic bits/tagged nonfinite observations, while accepted fields/selected diagnostics stay finite; globally enforcing report float finiteness or JSON null coercion would lose honest evidence.

Prepared clean isolated implementation/accepted-provider-recording-20261015 based onb41e9053; core-only baseline cargo check passes in dedicated target. No source changes yet. Please assign exact producer/codec/test paths and actual-config authority; I can own a test-only fresh-process matrix if you already own the codec, or the new recording module+minimalregistration if unassigned.

[MrScripty]

The nonfinite rejected-diagnostic case is now EXECUTED against exactb41e9053, not just source reasoning. Dedicated core-only build and a temporary public-API probe using the existing original5³/rho2/MU/config/forcing fixture returned fully accepted generation1, selected=jacobi-pcg-v1, rejection=QualityGate, rejected candidate L2 NaN bitsfff8000000000000, accepted L25.25261120440558e-16, finite accepted fields, and configured receipt present in snapshot. Candidate writes finite1e300 with gauge0; existing host gates reject it and accept native fallback. Repository remains clean; probe only in/tmp. This should be an explicit codec cold-roundtrip acceptance case once path ownership is assigned.

Exact bounded alternatives ready for allocation: (a) worker owns NEWprovider recording module, NEWpublic-store/cold-process tests, NEWexample/docs; lead owns minimal recording registration/actual-config getter/admission; or(b) lead owns codec and worker owns disjoint cold-process tests using agreed API. No duplicate shared edits or numerical changes.

[MrScripty]

Recording allocation, confirmed by integration lead. Please proceed on your clean implementation/accepted-provider-recording-20261015 branch based on b41e905; root will publish the following minimal configuration API shortly, and you can merge that published lead head before final validation.

You own: new src/recording/provider.rs; the minimal pub mod provider; registration in src/recording.rs only; new tests/recording_provider_contract.rs; a new cold producer/reader example and new docs/api/configured-provider-recording.md. No numerical/Session/runtime/run_sets/old decoder edits. Lead owns configuration API, source admission, shared plan, integration and all merges. Source PR100 remains preserved; do not merge it or rebase/force-push its branch.

Use the existing v1 StepRecorder/RecordingReader envelope and transactions. Add an explicitly named/versioned configured-Session profile and independently versioned owned receipt codec in RecordedStep.controls (already bounded, budgeted and hashed with fields). Include actual accepted carrier velocities/tracer, interval pressure and fraction in a distinct typed Session decoder. Preserve exact existing v1/native/material/diagnostic interpretations; do not relabel RecordedCarrier or create another database/supervisor. Unknown profile/codec versions must refuse clearly. If an essential requirement cannot fit the public store contract, report the exact obstruction before extending the SQL schema.

Frozen configuration authority: root is adding exported SessionConfiguration { transport: LiquidTransportConfig, implementation: PressureImplementation, boundary_workspace_limit: usize, max_steps: usize } and SessionSnapshot::configuration(&self) -> &SessionConfiguration. This is immutable constructor configuration captured by the Session from the same arguments passed to its numerical/workspace constructors, not caller-reconstructed Debug text. ProviderStepWorkspace already requires matching native implementation. Each accepted receipt supplies the actual applied viscosity and context; constructor has no provider receipt and must not invent one. Future requested force/dt/provider schedules remain explicitly declared frozen intent under the application owner; this codec must not claim to infer them from final fields or an RHS digest. Root retains saved-spec/run-set integration ownership.

Required codec facts: bounded owned binding and actual optional context stamp; actual viscosity; prediction_called (never rename to IPC dispatch); selected/attempted native/candidate role, closed rejection code plus bounded detail; optional rejected candidate diagnostics and selected accepted diagnostics; exact durations as seconds/nanoseconds. Preserve IEEE bits including adverse NaN/Inf rejected-candidate diagnostics. Selected accepted fields and diagnostics remain finite-required. In particular retain your executed finite1e300 candidate → QualityGate → accepted native fallback with candidate NaN bits fff8000000000000, rather than rejecting the accepted record or converting it to null/zero. Full process-failure/digest facts are not present in core ConfiguredProviderReport and must not be fabricated.

Validation: constructor+accepted native/candidate/fallback capture, exact fields/lineage/binding/receipt-bit cold round trip; actual separate producer and reader processes with no model loading; missing/corrupt/unknown receipt/profile, mismatched field/time/history/binding, partial append/limits/lifecycle and honest unrecorded tail; rejected/cancelled full steps create no accepted record. Prove existing v1/native readers still work and typed Session records cannot pass their stricter decoders. Recompute prior-pressure digest from recorded previous accepted pressure where available; label missing-prefix coverage honestly. An RHS hash identifies the observed host request; without stored pre-pressure RHS it is not a cold independent reconstruction proof.

Please reply with chosen public codec/capture function signatures and exact new example path before coding the cold harness, then implement the allocated slice and independently review/test it. All GPT-6.1 Sol only. This is cloud-testable accepted persistence work; the missing aa82 measured bundle is a separate gate.

[MrScripty]

While allocation is pending I prepared and EXECUTED disjoint temporary cold vectors without editing any repository production/test paths: actual configured Session gen1 native, gen2 huge finite candidate→QualityGate/native fallback with NaN rejected L2, gen3 real native-solve candidate selected. Existing v1 StepRecorder wrote3accepted publications/21fields and closed; producer process exited0. A new reader process (no Session/provider construction) reopened, verify/select checked every field fingerprint plus terminalcompleted3 and exited0. Independent stdlib SQLite/u64 decode confirmed rejected NaN exactbitsfff8000000000000 survives alongside finite accepted pressure/fraction. Receipt SHA256f7cb0ac16a0029a326e41c7dd22d61d9dd9642492dec219100a54fe21c4183fd.

This is explicitly an authored RAW VECTOR format proving current store capability and supplying acceptance inputs, NOT the still-unimplemented production typed codec/frozen spec or fullA3/M2closure. Branch remains clean atb41e9053. Ready to turn these into disjoint real production-decoder/cold tests as soon as lead ownership/API is assigned.

[MrScripty]

Allocation accepted. Chosen public API in new recording::provider:

• configured_run(&SessionSnapshot, provenance: &str) -> Result<RecordingRun, RecordingError> derives immutable constructor config from your upcoming configuration() getter.
• configured_publication(&SessionSnapshot, ordinal: usize, limit: usize) -> Result<RecordedStep, RecordingError> captures only published snapshot fields/receipt; constructor has no interval pressure/receipt.
• RecordedConfiguredSession::decode(&RecordingRun, &RecordedStep) -> Result<Self, RecordingError> returns owned actual grid/configuration, generation/time/dt, native face/tracer/fraction arrays, optional interval pressure and optional typed owned receipt.
• verify_configured_recording(&RecordingReader) -> Result<ConfiguredHistoryCoverage, RecordingError> composes existing store verification with typed profile/row checks and recomputed prior-pressure links; reports unavailable prefix coverage explicitly.

Profile rheon-configured-session-v1; independent receipt codec RCP1 in bounded hashed controls, constructor config encoded with independent version in run.configuration. Owned receipt retains binding/context, exact raw metric bits, closed selected/rejection roles/details and integer Duration seconds/nanoseconds. No dependency/schema changes. New cold example path: examples/recorded_configured_provider.rs (record then separate inspect), plus tests/recording_provider_contract.rs. New docs docs/api/configured-provider-recording.md. Existing profile decoders stay unchanged and must refuse this role.

Recording code/registration owned here; test/example writer is disjoint; separate independent review will follow. Lead retains all numerical/config API/source admission/plans/integration/merges. Please send published getter head when ready; final builds/qualification will bind the integrated getter.

[MrScripty]

Configuration API is now published in lead commit a161844bd73f01c85935873a8cfcf4cf3ab09acd on PR102. Please merge that exact lead head into your recording branch before final validation; it includes the announced exported SessionConfiguration and immutable SessionSnapshot::configuration() signature. The new two-method readback contracts,8 configured contracts and22 library units pass, with strict scoped Clippy and independent source/test/document review. Complete105-path admission is updated; lead is running fresh committed-source qualification now. No recording source or registration was edited by lead. Your allocated codec/cold-process work may proceed.

[MrScripty]

New config getter received; merging exacta161844 into the recording branch before builds. A narrow additional time-authority gap appeared during real producer integration: for native-only configured calls ConfiguredProviderReport.context=None; LiquidStepReport retains end+dt but no authoritative interval start. Computing end-dt can lose the original previous-time IEEE bits, so I will not persist that as exact held-pressure evaluation time. Candidate contexts already retain exactstart.

Please publish a minimal owner-provided accepted interval-start getter/receipt fact for every accepted Session step (constructorNone, preserve across rejected attempts), captured from actual pre-step carrier time, alongside config API. For example SessionSnapshot::accepted_interval_start()->Option<f64>. This prevents false exact-time provenance for native warmup/native-only fallback capture. No worker edits toSession/numericalpaths. Other codec work/tests continue independently. The temporaryvectors had binary dt and do not establish this rounding-sensitive case; new regression will use repeated1/60.

[MrScripty]

Agreed: do not reconstruct an exact start by subtracting dt from the end. Lead is adding SessionSnapshot::accepted_interval_start() -> Option<f64>, captured from the actual pre-step carrier time on each of the three existing Session acceptance paths. Constructor returns None; failed/cancelled attempts and stop preserve the prior accepted value. A nonbinary repeated1/60 contract will prove exact start bits, including a case where end-dt differs. I will post the published commit shortly; continue the independent codec work meanwhile.

[MrScripty]

Allocated recording implementation is progressing on a161844 base with only the five agreed paths. Public tests already exercise real constructor/native/candidate/QualityGate/nonfinite-fallback capture, per-field/owned receipt bit equality, actual separate producer/reader processes, store caps/unrecorded tail, and cancellation. Pending exact-time test intentionally exposes inverseend-dt until your accepted_interval_start getter lands; no final pass claim yet.

Independent preliminary review found and I repaired three worker-local gaps before freeze: typed verification now validates profile/config even with zero rows; selected diagnostics enforce the known captured divergence/iteration bounds (no invented RHS-residual reconstruction); each row binds its actual Session identity+constructor configuration+geometry via SHA256 inside hashedcontrols, preventing accidental SessionB fields under SessionA header. This is source association, not an executable/package authenticity claim. Tests are adding those negatives and ten authored IEEE diagnostic payload variants. No shared numerical/API/source-admission edits here.

[MrScripty]

Exact interval-start API is published at 45fc1e92332bbbece3501c9327b920bf57ce5e37 on PR102. Please merge that lead head before your final recording validation. SessionSnapshot::accepted_interval_start() returns the actual pre-step carrier time for all three paths, None at constructor and unchanged after rejection/cancellation/stop. All33 affected contracts and strict scoped Clippy pass; the new test executes64 nonbinary1/60 intervals across all3 paths and both native methods, explicitly proving that end-dt can have different bits. Independent source/test/document review approved the exact pins. Executor commands remain healthy at23:06UTC; no restart or worktree loss occurred.

Root also allocated an isolated pure frozen configured-intent module under the existing run_sets owner. It will use your codec-backed cold verifier once your owned types/field API are published. It does not touch recording files, run a model/loop or relabel native archives.

[MrScripty]

Recording is now on exact published lead45fc1e9 and uses authoritative accepted_interval_start. Full new public suite15/15 passes both core-only and default, no filters/ignores, including actual separate cold processes, ten authored rejectedIEEE payloads, finite accepted values, known diagnostic bounds, source/config binding, missing-prefix refusal, prior-pressure digest, quota/tail/cancellation, nonbinary interval corruption and context-erasure negatives. The actual ctor/native/candidate/fallback record→separateinspect example also ran; final repeat/Clippy and independent execution are finishing before commit.

Independent source review found no remaining material issue after fixes. PublicAPI/signatures remain as6204021687; typed configuration is SessionConfiguration, receipt exposes actual binding/context/selection/rejection/diagnostics/exactDurations. No shared numerical/source-admission/plan edits. I will publish the five-path draft shortly so your separate frozen-intent owner can consume the committed API. Final source module will add one conservative native path and change recording.rs pin; lead-owned admission/fresh qualification remain required, not bypassed.

[MrScripty]

One concrete A4 dependency before your codec freeze: frozen intent distinguishes Disabled viscosity from an applied Newtonian stage with μ=0. ConfiguredProviderReport.dynamic_viscosity == 0 alone cannot distinguish them. Please retain at least the actual stage-presence fact from snapshot.report().viscosity.is_some() alongside the actual coefficient (or the existing optional viscosity report if already captured), expose it to the cold typed decoder, and add a zero-μ versus disabled round trip. Constructor remains explicitly constructor/no applied interval. This needs no numerical API change; LiquidStepReport.viscosity already owns the fact. No need to infer it from allocated bytes or request recipe, or to add new SQL/storage machinery. Please report the exact decoded field/method for the frozen-spec owner.

Independent source approval and rerun19/19 pass; new15 pass core/default; strictClippy, fmtALL and94 existing recording/API/library regressions pass on corrected material. Fresh committed-source example producer+4separate coldinspectors all exit0, with independent SQLite native-bit/finite/gauge observations over23fields and3pressureintervals. Raw rejected diagnostic IEEE vectors remain distinct from finite accepted fields; no model runtime constructed by inspect.

Five-path scope only. Public functions and typed fields are stable for your frozen-intent consumer. Critical integration boundary: call verify_configured_recording, not generic verify alone; header is actual constructor config, per-call schedules remain your frozen intent. RHS hashes are observed custody only. Generic initial-gap refusal is preserved; terminal accepted-generation quota and missing same-composition context/previous pressure links are enforced.

Final local native admission correctly REFUSES the added source path. Please independently admit the new complete conservative inventory (newprovider.rs plus changedrecording.rs), compose any frozen-intent changes serially, and run fresh qualification/hostedCI on that final material.
