Safe outputs: pre-validate dispatch_workflow required inputs and downgrade missing-input failures to non-fatal

[Copilot]

safe_outputs was failing the entire job when a dispatch_workflow message omitted a target workflow’s required workflow_dispatch input (e.g. message for haiku-printer), even when all other safe outputs succeeded. This change adds required-input awareness to dispatch handling and treats that specific validation failure as report-only.

• Compile-time: capture required dispatch inputs

  • Extended DispatchWorkflowConfig with required_inputs (workflow -> []requiredInputName).
  • During safe-output config population, extract required workflow_dispatch.inputs from target workflow definitions and persist them into handler config.

• Runtime: pre-dispatch validation in dispatch_workflow handler

  • Before calling Actions dispatch API, validate message.inputs against compile-time required_inputs.
  • On missing required fields, return a typed validation result (success: false, reportOnly: true) with actionable error text naming the missing input.

• Runtime: normalize API missing-input errors

  • If GitHub returns 400/422 with Required input 'X' not provided, translate it to the same typed report-only validation error instead of surfacing raw REST failure text.

• Job outcome semantics: report-only failures

  • Updated safe output failure partitioning to honor explicit reportOnly: true on results (in addition to existing type-based report-only rules), so a single malformed dispatch does not make safe_outputs red.

// dispatch_workflow.cjsconstrequiredInputs=Array.isArray(requiredInputsByWorkflow[workflowName])
? requiredInputsByWorkflow[workflowName]
: [];constmissing=requiredInputs.find(name=>!Object.prototype.hasOwnProperty.call(inputs,name));if(missing){return{success: false,reportOnly: true,error: `Validation failed for dispatch_workflow "${workflowName}": missing required input "${missing}".`,};}

Pull request overview

This PR enhances the safe_outputs “dispatch_workflow” handler by capturing required workflow_dispatch.inputs at compile time and using that metadata at runtime to pre-validate dispatch messages, converting “missing required input” failures into report-only results so they don’t fail the entire safe_outputs job.

Changes:

• Compile-time: extract and persist per-workflow required workflow_dispatch inputs into safe-outputs handler config (required_inputs).
• Runtime: validate dispatch_workflow messages against required_inputs before dispatch, and normalize certain 400/422 API errors into report-only validation failures.
• Job semantics: extend report-only partitioning logic to honor an explicit reportOnly: true flag (in addition to type-based rules).
