Artifacts

culsma run writes staged JSON artifacts into the output directory.

File	Producer	Meaning
summary.json	CLI summary	Counts and run status.
ast.json	parser/frontend	Parsed source program.
ir.json	compiler	Canonical IR.
validate.json	semantic validator	Semantic diagnostics.
typecheck.json	typechecker	Type and unit diagnostics.
plan.json	plan lowering	Executable plan.
run.json	runtime	Runtime state, events, diagnostics, and user result.
output.json	CLI run output	Machine-readable returns plus derived report.
result.json	report projection	Derived lab_report_v1 report summary.

The exact content of these files is intended for inspection and reproducibility. Source language authoring uses .culs files, not generated IR or plan JSON.

output.json uses culsma_run_output_v1. Its top-level returns field is the protocol return value surface; its report field is the derived lab_report_v1 execution report.

Minimal Run Output

For examples/minimal/public_minimal.culs, the verified run reports:

Field	Value
headline	Experiment completed successfully with no runtime errors.
completed steps	5
mutation steps	1
final product	Target
final product volume	5.0uL
primary component	BUF01
touched containers	Source, Target

The terminal and output.json return the protocol output separately:

return:
  Target (tube)
    volume: 5 uL
    mass: 5 mg
    components:
      BUF01: 5

The result.json report is a derived projection over runtime state and events. It is not a replacement for the source protocol, the protocol return, or the execution plan.
