resolveModule() ignores engine parameter, defaults to Codex

[buckstrdr]

When using resolveModule() in a workflow file, the engine parameter is ignored. The module always executes using Codex regardless of the specified engine.

Steps to Reproduce:

1. Create a workflow with resolveModule() specifying engine: 'claude':
   resolveModule('check-task', {
   engine: 'claude',
   model: 'sonnet',
   loopSteps: 6,
   loopMaxIterations: 30,
   loopSkip: ['runtime-prep']
   }),

2. Run the workflow with codemachine

3. Observe the check-task module execution

Expected Behavior:
Module should execute using Claude Code with the sonnet model.

Actual Behavior:
Module executes using Codex, causing error:
[CYAN]● Codex is analyzing your request...
Task Completion Checker failed: Codex CLI exited with code 1
{"type":"error","message":"unexpected status 400 Bad Request: {"detail":"The 'sonnet' model is not supported when using Codex with a ChatGPT account."}"}

Note: resolveStep() correctly respects the engine parameter - only resolveModule() has this issue.

Environment:

• CodeMachine version: (run codemachine --version)
• OS: Linux (Ubuntu)
• Node: v22.20.0

Workaround:
Use Codex-compatible settings for modules:
resolveModule('check-task', {
engine: 'codex',
model: 'gpt-5',
// ...
}),
