[hash-release]

This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Releases

@blockprotocol/graph@0.5.0

Minor Changes

• Make rightEntity / leftEntity on LinkEntityAndRightEntity / LinkEntityAndLeftEntity possibly undefined, reflecting what getOutgoingLinkAndTargetEntities / getIncomingLinkAndSourceEntities actually return when a link's has-right-entity / has-left-entity edge is not resolved into the subgraph. Previously an unsafe cast hid this, allowing runtime crashes when consumers indexed into a missing target entity array. (@TimDiekmann, #8992)

@hashintel/ds-components@0.3.0

• Breaking change: Refactor SegmentedControl api and ui (@alex-e-leon, #9275)

@hashintel/petrinaut@0.0.17

Patch Changes

• Improve narrow-panel layouts and scrolling in Simulation Settings, the timeline, bottom-panel tabs, and sidebar subviews. (@kube, #9074)

• Rename the AI assistant tab to "AI", use neutral assistant copy, place topBarStart immediately before the net title, and add slots.titleStyle for host-defined title styling. (@vilkinsons, #9084)

• Replace the optimize host capability with createOptimizationRun, attachOptimizationRun, and cancelOptimizationRun, enabling resumable runs and automatic reconnection. (@kube, #9066)

• Add uuid token attributes with automatic generation and Uuid.generate() / Uuid.from() helpers. (@kube, #8953)

• Add range() to scenario code, fix common array methods in scenario expressions, and show scenario compilation errors in Simulation Settings. (@kube, #9092)

• Clarify that Predicate transitions fire immediately when their guard is true and input tokens are available. (@YannisZa, #9097)

• Add the string token attribute type, stored via per-run interning. Editing a type's schema now migrates stored initial state (values convert, falling back to the new type's default). (@kube, #8953)

• Add a scenario-first optimization interface with flat parameter search spaces, metric objectives, and progressive step results. (@kube, #9051)

• Add integer and boolean token attribute types. (@kube, #8764)

• Improve inhibitor arc styling. (@CiaranMn, #8846)

• Allow metrics to read resolved net parameters through parameters.<variableName>; scenario parameters remain unavailable. (@kube, #9043)

• Add Actual mode for read-only live execution, including host event streams, a timeline, an event log, and recording exports. (@kube, #8829)

• Replace Babel with the HIR compiler for user code. Unsupported TypeScript now produces diagnostics instead of running. (@kube, #8981)

• Allow hosts to disable SDCPN extensions and global parameters. (@kube, #8763)

• Improve spacing for scenario and parameter controls in Simulation Settings. (@kube, #9078)

• Add subnet definitions, component instances, and wiring support to Petrinaut. (@kube, #8662)

• Add editor support for read input arcs, including arc controls and distinct canvas rendering. (@kube, #8774)

• Add a "Pre-deployed Constellation" scenario to the Probabilistic Satellite Launcher example. (@kube, #9092)

• Use a shared fixed seed (PETRINAUT_DEFAULT_SEED) for interactive simulation and optimization runs, so playing a simulation reproduces an optimization trial given the same configuration. (@kube, #9073)

• Export the token value codec and compileUserCode from @hashintel/petrinaut-core. (@kube, #8943)

• Use a packed token frame layout and simplify the getPlaceTokens(place) and buildMetricState(frame, places) APIs. (@kube, #8944)

• Add Panda build metadata and a shared preset for host style generation, and namespace Petrinaut keyframes to prevent theme collisions. (@alex-e-leon, #9071)

• Updated dependencies:

  • @hashintel/ds-components@0.3.0
  • @hashintel/petrinaut-core@0.0.3

@hashintel/petrinaut-core@0.0.3

Patch Changes

• Replace the optimize host capability with createOptimizationRun, attachOptimizationRun, and cancelOptimizationRun, enabling resumable runs and automatic reconnection. (@kube, #9066)

• Add uuid token attributes with automatic generation and Uuid.generate() / Uuid.from() helpers. (@kube, #8953)

• Expose the per-type policy registry (TYPE_POLICIES) and related helpers. (@kube, #8953)

• Add an optional seq sequence number to every optimization event so detached, reconnectable optimization runs can be resumed from a cursor. (@kube, #9067)

• Add range() to scenario code, fix common array methods in scenario expressions, and show scenario compilation errors in Simulation Settings. (@kube, #9092)

• Fix Predicate transitions so true guards fire on the first and every consecutive simulation frame. (@kube, #9096)

• Prevent newly loaded nets from being marked as changed when optional fields are absent. (@kube, #9199)

• Add the string token attribute type, stored via per-run interning. Editing a type's schema now migrates stored initial state (values convert, falling back to the new type's default). (@kube, #8953)

• Add scenario-first optimization manifests with flat parameter search spaces, metric objectives, and hardened server-side scenario execution. (@kube, #9040)

• Add integer and boolean token attribute types. (@kube, #8764)

• Allow metrics to read resolved net parameters through parameters.<variableName>; scenario parameters remain unavailable. (@kube, #9043)

• Add multi-seed optimization trials through execution.seedsPerTrial, including per-seed replicates, budget accounting, and the exported deriveRunSeed helper. (@kube, #9224)

• Add Actual mode for read-only live execution, including host event streams, a timeline, an event log, and recording exports. (@kube, #8829)

• Replace Babel with the HIR compiler for user code. Unsupported TypeScript now produces diagnostics instead of running. (@kube, #8981)

• Define the optimization protocol's response shapes as Zod schemas (petrinautOptimizationDescribeParameterSchema, petrinautOptimizationDescribeResultSchema, petrinautOptimizationReplicateSchema, petrinautOptimizationEvaluateResultSchema). The existing PetrinautOptimizationDescribe*/EvaluateResult types are now derived from them and are unchanged. (@kube)

• Allow hosts to disable SDCPN extensions and global parameters. (@kube, #8763)

• Add subnet definitions, component instances, and wiring support to Petrinaut. (@kube, #8662)

• Fix compilation of real transition-kernel attributes that conditionally return a number or a distribution. (@ShiroKSH, #9028)

• Support read input arcs across SDCPN parsing, simulation, AI arc creation, and typed code inputs. (@kube, #8774)

• Add a "Pre-deployed Constellation" scenario to the Probabilistic Satellite Launcher example. (@kube, #9092)

• Use a shared fixed seed (PETRINAUT_DEFAULT_SEED) for interactive simulation and optimization runs, so playing a simulation reproduces an optimization trial given the same configuration. (@kube, #9073)

• Export the token value codec and compileUserCode from @hashintel/petrinaut-core. (@kube, #8943)

• Use a packed token frame layout and simplify the getPlaceTokens(place) and buildMetricState(frame, places) APIs. (@kube, #8944)
