FE-1688: Remove the Optimizations tab and run optimization inside Experiments

[kube]

Important

Experimental
Behind the Parameter sweeps and In-browser optimization feature flags.

Summary

Before this PR, the Simulate panel had an Optimizations tab beside Experiments and Scenarios. A study was created there from its own drawer, with the objective, the parameter bindings and the constraints, and ran through a channel of its own with a detached objective, Pause and Resume, a full view and a website route. A sweep could also hand its Parameters card to the optimizer, so the same search existed twice, in two places, with two sets of results.

This PR keeps one path. The Optimizations tab, its drawers, the full view, the standalone study channel and the website's /optimization route are deleted. Constraints become a property of the experiment: with both flags on, the first Sweep toggle on a saved scenario's parameter adds a Constraints section to the Create Experiment drawer, one list of parameter and state rows with a pass threshold, checked as you type, recorded with the experiment and listed behind a fold in the sweep's Parameters card. A study started from the card enforces them exactly: a parameter constraint prunes a step before anything simulates, a state constraint runs as a 0/1 indicator metric on every batch so a step's pass share is its run count. The experiment drawer shows the study's displays only once a study exists, and holds that shape through running, stopped, failed and later studies: a headline over the header, Steps and Steps clear columns, the Constraints and Sensitivity analysis cards after the metric charts and the steps table under them. Objective by step stays under the sliders.

Changes

Constraints on the experiment

• Constraints section in the Create Experiment drawer

  Appears with the first Sweep toggle on a saved scenario when both flags are on, between Scenario and Metrics. One list of parameter and state rows with a kind chip, a reserved diagnostic line per row and the Pass threshold in the header once a State row exists.
  Rows compile through the constraint language session as you type; Create sweep stays disabled with the first failing row named in the footer.

• Constraints ride the experiment record

  CreateExperimentInput takes lowered constraints and a constraintPolicy; ExperimentRecord carries them with the scenario values it was created with.
  The sweep's Parameters card lists them behind a Show N constraints fold in its footer.

• Exact enforcement through the sweep-driven study

  A parameter constraint is judged at the snapped grid point before the sweep navigates; an infeasible draw costs one step and no simulation.
  A state constraint runs as a precompiled 0/1 indicator metric under a constraint:<id> id on every batch, so a step's pass share is runsPassed / runsTotal over the runs that reported.
  A step whose point measured no verdict for a declared state constraint is pruned with that constraint named.
  A sweep with state constraints computes on the CPU; the drawer's WebGPU switch greys out while a State row is drafted.

• GPU availability re-lowers the net after a pause in typing

  The drawer's WebGPU gate waits 250 ms after the last metric or constraint edit and keeps the previous reason meanwhile.

The study in the experiment drawer

• Study displays appear once a study exists and keep their shape

  Headline at the right of the title line, Steps and Steps clear columns after Compute, the Constraints and Sensitivity analysis cards in the metric grid at the metric plot height, the steps table under both columns.
  The drawer changes shape once, at the first Optimize, and holds it across running, stopped, failed and later studies.

• Stop is the only study control

  Pause and Resume go with the standalone study; Stop ends the search where it stands and the point refines to the run budget.

• One wording for the study's progress

  describeStudyProgress reads the study alone and no longer prints Cancelled for every sweep study.

• Optimize prompt and objective strip are keyed per experiment

  Swapping two sweeps in the same drawer resets the prompt's metric picker and the strip.

Deletions

• Optimizations tab, its list, create and view drawers, full view and study results view

  SimulateViewMode loses optimizations; the drawer state loses create-optimization; Simulate shows Experiments and Scenarios.

• Standalone study path

  The channel, the connected study, point refinement, the detached objective, the sampler of detached objectives, Pause, Resume, Continue, Refine and Retry, the remote-run re-attach and reconnect machinery.
  The pause path goes end to end: pauseOptimizationRun leaves the optimization capability, the paused event leaves the browser runtime's schema and worker messages.
  OptimizationStatus loses paused; OptimizationRecord loses errorCategory, errorDiagnostics, connectionState, computeBackend and axes; OptimizationConnectionState and the error taxonomy types are gone.
  The surface grid sampler, its quad-tree helpers and the changesets of the deleted features go with them.

• Navigation and website

  The optimization resource, the create-optimization overlay, the simulate presentation and openPetrinautOptimizationFullView leave the navigation contract; old URLs carrying view=optimizations, overlay=create-optimization or present= normalise to the baseline.
  The website drops its /optimization route, the optimizer-service provider, the VITE_PETRINAUT_OPT_PROVIDER variable and the --with-optimizer-service flag of its dev script.

• Docs

  The optimization guide folds into the experiments guide; the Optimizations tab and connected-study architecture pages are deleted, the browser runtime, sweep orchestration, sweep surface and ad-hoc form pages describe the folded product.

Review fixes

• Constraint indicators sample every run that did not error

  sampleRuns: "all" also sampled errored runs, so an errored run was binned as passed or failed against the documented contract that it counts in neither runsPassed nor runsTotal.
  petrinaut-core gains a sampleRuns: "notErrored" mode, the indicator specs use it, and a user-defined metric test with an errored run in the batch pins the counts.

• Core gets its own changeset

  One changeset bumped both packages with a UI sentence while the core's pause API removal was never released, so core had nothing to announce there.
  fold-optimization-into-experiments bumps @hashintel/petrinaut alone and metric-sample-not-errored-runs bumps @hashintel/petrinaut-core for the new sampling mode.

• drawer-frame.tsx is the frame parts' one public door again

  Results view, results model, the stories, the objective strip and the same-shaped bypasses imported from the drawer-frame/ subtree.
  The root file re-exports the parts and every adopter imports from it; lint:tsc and the arch-docs lint pin it.

• Sweep evaluator binds scenario.* by each scenario parameter's type in its constraint check

  It bound the snapped values' 0/1 transport while == compares by identity, so scenario.flag == true held for no draw.
  resolveTrialScenarioBindings decodes the snapped values as the scenario compiler binds them, and a create-sweep-trial-evaluator.test.ts case pins scenario.isolation == true pruning a draw with the switch off and holding for one with it on.

• Failed study parks the sweep on the best step it tried

  Both failure paths settled the sweep with no best, so it parked uncapped on the point whose batch had just rejected.
  runAttachLoop carries the best step beside the sequence number and hands it to both failure paths; two provider.test.tsx cases pin a rejected batch and a study_failed event parking on the best step.

Known issues

• Parameter constraints read parameters.* at the net's defaults

  The sweep path cannot lower the scenario's overrides on the main thread, so a constraint over an overridden net parameter is judged at the default value. Routing through the sweep session's compiled scenario is the follow-up.

• Remote optimizer hosts have no optimization surface

  The HASH embed's optimization bridge and the With real optimizer story still mount a remote capability, but Optimize and Constraints require an optimizer that runs in the browser. A remote sweep evaluator, or deleting that wiring, is the follow-up.

• Story fixtures mix models

  The drawer stories put a supply-chain study over the SIR sweep, so the steps table's parameter names do not match the sliders.

• @local/petrinaut-optimizer-client is an unused dependency of the website

  Its last importer went with the route; removing it needs a lockfile change and a regenerated task-dependencies document.

Test coverage

• create-experiment-drawer.test.tsx:

  Constraints section gating, row authoring and diagnostics, the pass threshold, the WebGPU switch under a State row, lowering at submit.

• lower-constraint-drafts.test.ts, constraint-lsp.test.ts, constraint-indicators.test.ts:

  Drafts lower to constraints, blank rows are ignored, indicator specs per state constraint.

• create-experiment.test.ts, sweep-optimizer.test.ts, create-sweep-trial-evaluator.test.ts:

  The record carries constraints and scenario values, the manifest fixes non-swept parameters at the record's values, an infeasible draw is pruned before navigation, state verdicts come from the indicator's pass share.

• user-defined.test.ts in petrinaut-core:

  A min-over-time indicator sampled over the runs that did not error bins to the 0/1 pass counts the evaluator reads, and a batch with an errored run counts it in neither bin.

• compile-net-shader.test.ts:

  The notErrored mode emits the same sampling guard as all, since the shader never samples a halted run.

• experiment-results.test.tsx, view-experiment-drawer.test.tsx, study-header.test.tsx, describe-study-progress.test.ts, the study card tests under experiment-results/:

  Headline, Steps columns, cards and table appear only with a study, the layout signature is equal across study states, the constraints fold, Stop while driving, the prompt resets when the drawer swaps experiments.

• use-gpu-availability.test.tsx:

  One lowering for a burst of metric edits, the previous reason kept while pending.

• navigation/index.test.tsx, editor-provider.test.tsx, simulate-view.test.tsx, simulation-creation-drawer.test.tsx, provider.test.tsx:

  No optimization resource, overlay or presentation; two Simulate tabs; a study needs a sweep origin; a failed study parks the sweep on the best step it tried.

• Website example-search.test.ts, navigation-search.test.ts:

  Legacy optimization params normalise to the baseline.

How to test

• Open Petrinaut preview on Vercel
• Viewport controls > Settings > Simulation > Parameter sweeps on, In-browser optimization on
• Menu > Load example > SIR Epidemic Model
• Switch to Simulate

  Expect two tabs, Experiments and Scenarios

• Experiments > Create
  • Scenario > Seasonal Flu
  • Flip Sweep on infected_ratio

    Expect a Constraints section between Scenario and Metrics

  • Add parameter constraint > type scenario.infected_ratio < 0.5

    Expect the row to compile with no diagnostic line

  • Add state constraint > type return state.places.Infected.count <= 900;

    Expect the Pass threshold in the section header and the WebGPU switch greyed

  • Add a metric on Infected, then Create sweep
• Parameters card > Show 2 constraints

  Expect both rows with their kind, label and code, the threshold under them

• Parameters card > Optimize > Start

  Expect the headline on the title line, Steps and Steps clear columns, the Constraints and Sensitivity analysis cards after the metric chart, the steps table under them, Objective by step under the sliders

• Stop

  Expect the same cards and table in place, sliders unlocked, the outcome on the headline

• Open /?view=optimizations

  Expect the URL to settle on the baseline with the Experiments tab shown

PR Summary

Medium Risk
Large product and API surface change (navigation, experiments context, optimizer protocol) though largely behind experimental flags; constraint enforcement and sweep-orchestration paths need careful review.

Overview
Removes the standalone Optimizations workflow and makes parameter sweeps the only place to run in-browser studies. The Simulate Optimizations tab, create/view drawers, full-view presentation, detached objective APIs, and Pause/Resume on the browser optimizer are deleted; legacy URLs (view=optimizations, present=, etc.) normalize to Simulate on Experiments.

Optimization now starts from a sweep’s Parameters card (Optimize / Stop), with study UI living in the experiment drawer (headline, Steps / Steps clear, Objective by step, Constraints and Sensitivity analysis cards, steps table). Constraints move onto the experiment: the create-sweep drawer gains a Constraints section (parameter + state rows, pass threshold), stored on the record and enforced by the sweep-driven study (parameter constraints prune before simulate; state constraints run as hidden constraint:<id> indicator metrics).

Website/dev cleanup: /optimization, VITE_PETRINAUT_OPT_PROVIDER, optimizer dev proxy, and --with-optimizer-service are removed; only the in-browser optimizer path remains.

Core: adds metric sampling mode sampleRuns: "notErrored" (used for state-constraint pass counts; WebGPU guard matches all for halted runs) and drops the paused optimization event / pauseOptimizationRun API end-to-end.
