The YAML compiler was using SubWorkflowPlaceholderStep that returned
next() immediately. Replaced with real SubWorkflowStep from wfe-core
that starts child workflows and waits for completion events.
Added regression test verifying the compiled factory produces a step
that calls host_context.start_workflow() and returns wait_for_event.
Nextest cover profile for cargo llvm-cov integration.
Update existing test imports from load_workflow_from_str to
load_single_workflow_from_str for backward compatibility.
Compiler dispatches type: workflow to SubWorkflowStep. Validation
detects circular workflow references via DFS with coloring. Cross-
workflow reference checking for multi-workflow files. Duplicate
workflow ID detection. 28 edge case tests for validation paths.
YamlWorkflowFile supports both single (workflow:) and multi (workflows:)
formats. WorkflowSpec gains typed inputs/outputs declarations.
Type string parser for inline types ("string?", "list<number>", etc.).
load_workflow_from_str returns Vec<CompiledWorkflow>.
Backward-compatible load_single_workflow_from_str convenience function.
Phase 4 — Permission-gated HTTP fetch op:
- op_fetch with net permission check on every request
- globalThis.fetch() wrapper with .json()/.text() methods
- Supports GET/POST/PUT/DELETE with headers and body
Phase 5 — Module loader:
- WfeModuleLoader resolving npm: → esm.sh, https://, file://, relative paths
- All resolution paths permission-checked
- Bare path resolution (/) for esm.sh sub-module redirects
- Dynamic import rejection unless permissions.dynamic_import: true
- esm.sh auto-added to net allowlist when modules declared
Mandatory npm integration test (is-number via esm.sh).
25 new tests. 133 total deno tests, 326 total workspace tests.
