fix(workflows): enforce hermetic include references

[Wirasm]

Summary

• Problem: included workflows could bind undeclared parent state through shorthand when:, rejection prompts, Markdown refs, or deferred command bodies.
• Why it matters: reusable workflows need a hermetic declared interface; caller-ID collisions could consume the wrong governed data.
• What changed: validation covers every live current reference surface, and included named commands are resolved, validated, snapshotted, namespaced, and input-bound at load time.
• What did not change: no parent-run execution, structured I/O, runtime fan-out, provider capability, database, expression-language, or named-script templating changes.

UX Journey

Before

include command-first block -> flatten child, defer command body
matching parent id          -> hidden child ref can bind at runtime

After

include command-first block -> [resolve + snapshot command body]
declared caller `with:`     -> [bind `$INPUTS`]
child-local refs            -> [validate + namespace]
hidden ref/unreadable body  -> [actionable load error]
executor                    -> deterministic flat DAG

Architecture Diagram

Before

workflow-discovery -> include-expander -> flat DAG -> dag-executor
       |                   |                             |
       +- reads commands   +- best-effort scan           +- loads command again
loader -> partial live-surface validation

After

workflow-discovery -> [~] include-expander ==> flat DAG -> dag-executor
       |                     |
       +- reads commands ----+- validate + materialize + bind + namespace
[~] loader -> validates canonical refs, when shorthand, and rejection prompts

Validation Evidence (required)

bun test packages/workflows/src/include-expander.test.ts packages/workflows/src/workflow-discovery-command-scan.test.ts  # 69 pass
bun test packages/workflows/src/loader.test.ts  # 249 pass

bun run check:bundled  # pass
bun run test:install  # pass
bun run validate  # exits 2 at pre-existing check:pi-vendor-map drift
bun run test  # unrelated existing CLI/server failures under parallel full-suite run

• Evidence provided: collision/no-collision, recursive commands, declared inputs, rejection prompts, shorthand, Markdown-live, unresolved-command, package-command, and composed graph tests.
• No command was intentionally skipped. bun run validate before and after implementation stops at identical installed Pi SDK/vendor-map drift. Independent broad gates show the same dependency drift in docs/providers; full parallel tests report unrelated CLI/server mock-sensitive failures. The workflows package and changed-file gates pass. CI is authoritative.

This preserves load-time composition and the flat static DAG; it adds no computation or expression surface. See packages/docs-web/src/content/docs/reference/workflow-language-constitution.md.

Security Impact (required)

• New permissions/capabilities? (No)
• New external network calls? (No)
• Secrets/tokens handling changed? (No)
• File system access scope changed? (No)
• If any Yes, describe risk and mitigation: N/A. Existing discovery reads the same paths; included command content is now snapshotted into the compiled definition.

Compatibility / Migration

• Backward compatible? (No — intentionally rejects hidden caller bindings and unresolved included commands)
• Config/env changes? (No)
• Database migration needed? (No)
• Upgrade: migrate hidden references to child inputs: plus caller with:. Ensure included commands resolve in package/project/user/enabled bundled scopes. Named scripts remain opaque and use INPUTS_* env values.

Human Verification (required)

• Verified scenarios: parent collision and no collision; local/enclosing nested refs; command and loop-command inputs; package/configured lookup; rejection prompts; shorthand when:; fenced refs; unresolved commands.
• Edge cases checked: rewrite-before-input ordering keeps passed parent refs parent-scoped; nested IDs remain body-local; named scripts remain untouched.
• What was not verified: feat(workflows): compose statically named workflow files inside the parent run #1764 parent-run composition, which does not exist yet and must add parity tests when implemented.

Side Effects / Blast Radius (required)

• Affected subsystems/workflows: workflow loading/discovery, include expansion, bundled workflow examples, include docs.
• Potential unintended effects: included command nodes appear as compiled prompt nodes; canonical refs used as Markdown examples must become placeholders.
• Guardrails/monitoring: source-oriented load errors, focused discovery tests, workflows package suite, post-expansion validation.

Rollback Plan (required)

• Fast rollback: revert this PR.
• Feature flags/config toggles: none.
• Observable symptoms: validation errors name the include, workflow, node path, command/field, offending ref, and inputs:/with: migration.

Risks and Mitigations

• Risk: snapshotting changes when command edits become visible.
  • Mitigation: rediscovery/reload recompiles current content, preserving deterministic composition.
• Risk: stricter Markdown handling invalidates examples.
  • Mitigation: runtime already substituted them; bundled examples now use $<node-id>.output, and docs explain the rule.
• Risk: a new substitution surface could drift.
  • Mitigation: synchronized walker comments and parity tests enumerate the four passes.

Summary by CodeRabbit

• New Features

  • Included workflows and loop commands now expand into prompts with inputs and properly scoped references.
  • Output references work across prompts, conditions, approval messages, code spans, and loop commands.
  • Included commands support custom folders and nested workflow structures.

• Bug Fixes

  • Invalid, unresolved, or out-of-scope references now fail loading with clearer errors.
  • Prevented incorrect resolution against similarly named parent nodes.
  • Resumed loops retain their paused prompt, including composed commands.

• Documentation

  • Standardized workflow output-reference examples and syntax.

📝 Walkthrough

Walkthrough

Included command and loop-command bodies are compiled during workflow loading. Output references are validated and namespaced across live fields, nested scopes, approval prompts, and command-backed prompts. Declared inputs bind included content, and unresolved or out-of-scope references fail workflow loading.

Changes

Workflow composition

Layer / File(s)	Summary
Reference-surface validation packages/workflows/src/loader.ts, packages/workflows/src/loader.test.ts, packages/workflows/src/include-expander.test.ts, packages/workflows/src/dag-executor.ts	Validation covers shorthand when, approval rejection prompts, workflow with values, loop prompts, and Markdown code spans. Errors identify the affected field.
Included command materialization packages/workflows/src/compiled-command.ts, packages/workflows/src/include-expander.ts, packages/workflows/src/include-expander.test.ts, packages/workflows/src/loader.test.ts, packages/workflows/src/workflow-discovery-command-scan.test.ts	Included command and loop-command bodies are resolved, input-bound, namespaced, and compiled into prompts. Nested loop groups are supported. Missing content and external references fail expansion.
Loop prompt snapshot resumption packages/workflows/src/dag-executor.ts, packages/workflows/src/dag-executor.test.ts, packages/workflows/src/schemas/workflow-run.ts	Resumed loops use persisted resolved prompt snapshots before loading fresh command content. Inline and command-backed loop prompts are persisted.
Workflow reference documentation .archon/workflows/defaults/archon-workflow-builder.yaml, packages/docs-web/src/content/docs/guides/authoring-workflows.md	Documentation uses $<node-id>.output syntax and describes command-backed input binding and load-time compilation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: ⚪ Minimal · up to 8a3c4

The workflow reference changes are merge-ready after normal checks and review; no actionable merge-blocking risk remains.

Suggestions (3 found)

Agent	Suggestion	Location
code-simplifier	Consider sharing the output-ref and input-macro node-text traversal after the behavior stabilizes. Deferred here because the two walkers intentionally cover different surfaces and a refactor would enlarge a correctness fix.	packages/workflows/src/include-expander.ts:149
code-simplifier	Consider extracting the repeated known-reference predicate and using matchAll in DAG validation. Deferred as non-blocking polish.	packages/workflows/src/loader.ts:421
code-simplifier	Normalize the optional command map once outside the include loop. Deferred as negligible and unrelated to correctness.	packages/workflows/src/include-expander.ts:600

Strengths

• Hermetic validation now covers canonical refs, when: shorthand, approval rejection prompts, Markdown-live refs, command bodies, and recursive loop scopes.
• Included command prompts support declared inputs while direct caller references fail with actionable migration guidance.
• Review findings were addressed with empty-body rejection, persisted loop prompt snapshots, cold-resume-safe private compilation metadata, and three-level nested-include coverage.
• Final specialist re-review found no remaining high-confidence issues; the full workflows package suite and workflows type-check pass.

Documentation Issues

• None. Include command compilation, lexical boundaries, script opacity, and paused-loop resume behavior are documented.

Verdict

READY TO MERGE

Recommended Actions

1. Let the refreshed GitHub Actions checks complete.
2. Keep feat(workflows): compose statically named workflow files inside the parent run #1764's future parent-run composition on the same lexical-boundary contract and add parity tests there.
3. Consider the advisory traversal simplifications in a separate refactor only if future surfaces make the duplication costly.

[Wirasm]

Addressed the remaining automated review suggestions in 8a3c42b: documented the when:/|| composition restriction and replaced the new broad as unknown as DagNode fixtures with satisfies checks. The return-type nit was already satisfied (compile(...): CompiledLoopCommand) and required no change.

Important Issues (2 found)

Agent	Issue	Location
silent-failure-hunter	Included-command discovery catches every project/configured-scope error and continues to lower-precedence scopes. Because this PR turns the scan result into the executable prompt snapshot, an unreadable or concurrently deleted repo command can silently execute a home or bundled command with the same name. Continue only when a scope has no match; after a match, surface read failures with command and path context as a per-workflow load/compilation error. Direct runtime command loading already fails explicitly in this situation.	packages/workflows/src/workflow-discovery.ts:457
code-reviewer	The new command-body ownership scan mistakes the valid include macro $INPUTS.output for the canonical node reference $<node>.output before input expansion runs. A block declaring an input named output is therefore dropped even when the caller supplies it. Exclude syntactically valid $INPUTS.<name> macros from the ownership scan while preserving rewrite-before-input ordering, and add a regression test.	packages/workflows/src/include-expander.ts:544

Suggestions (7 found)

Agent	Suggestion	Location
silent-failure-hunter	If compiled-loop metadata is present but has neither a string prompt nor error, fail explicitly instead of silently falling back to live command lookup. Reserve fallback for truly absent metadata on ordinary loop commands.	packages/workflows/src/dag-executor.ts:4204
pr-test-analyzer	Exercise included-loop cold resume through real filesystem discovery: discover, pause, delete the command, rediscover, resume from the persisted snapshot, and separately prove a fresh run fails before provider invocation. The current composed-loop case simulates deletion by passing a null map entry directly to the expander.	packages/workflows/src/dag-executor.test.ts:8472
pr-test-analyzer	Combine three-level composition with a command-backed loop nested inside one or more loop_group bodies. Existing tests cover three include levels and recursive loop placement separately, so deleting recursive symbol preservation could leave both green.	packages/workflows/src/include-expander.test.ts:564
pr-test-analyzer	Add the distinct whitespace-only loop.command case: the workflow remains discoverable with a private compilation error, a fresh execution emits one actionable failure, and no provider call occurs.	packages/workflows/src/include-expander.test.ts:884
comment-analyzer	Refresh stale comments that still claim validation cannot see bash/script/approval/cancel fields, that validation covers only when:/prompt:, and that includes add zero runtime machinery; included loop commands now carry private runtime-consumed metadata. Also fix “so an every canonical ref.”	packages/workflows/src/dag-executor.ts:784
type-design-analyzer	Consider central read/write/clone helpers for COMPILED_LOOP_COMMAND to contain repeated intersection casts and document first-write-wins and structuredClone preservation. The current union is useful and sufficiently typed, so this is advisory.	packages/workflows/src/compiled-command.ts:1
code-simplifier	Normalize the optional command-content map once and keep the node-ref and input-macro walkers separate; their different grammars and surface sets make a generic shared walker less clear.	packages/workflows/src/include-expander.ts:600

Strengths

• Hermetic validation now covers canonical references, shorthand when:, rejection prompts, Markdown-live references, resolved command bodies, recursive loop scopes, and parent-id collision cases.
• Compiled command prompts preserve caller-input ordering, local namespacing, cold-resume snapshots, and three-level top-level composition; named scripts remain opaque.
• Focused suites passed independently: include-expander 69/69, loader 249/249, discovery command scan 2/2, and DAG executor 451/451 (771 total).
• The full @archon/workflows package suite, workflows type-check, changed production-file lint, formatting, bundled-default generation check, and git diff --check all passed.
• bun run validate was run and exited 2 at check:pi-vendor-map. The identical command at clean origin/dev (2379a2c9) failed at the same gate, and this PR changes no dependency, lockfile, generator, or Pi vendor-map file; this is base/environment-only drift rather than a PR regression.
• GitHub CI is green on Ubuntu, Windows, Docker, docs, and CodeRabbit.
• A synthetic merge with the current PR fix(workflows): make Codex skill use explicit (#2498) #2533 head completed without textual conflicts. The PRs overlap authoring-workflows.md, dag-executor.test.ts, and bundled-defaults.generated.ts; regenerate bundled defaults after integration so neither generated snapshot is lost.

Documentation Issues

• packages/docs-web/src/content/docs/guides/loop-nodes.md:130 says every loop.command file is read when the loop starts. Included loop commands are now resolved and compiled during discovery, fail before a fresh AI turn when unresolved/empty, and resume from the persisted prompt snapshot. Document the ordinary-loop versus included-loop distinction.
• packages/docs-web/src/content/docs/guides/authoring-commands.md:29 says shared commands are loaded at runtime. Qualify this as the ordinary model and note that command bodies inside an include: are resolved and snapshotted during load-time composition.
• The changed authoring guide accurately covers hermetic scope, command compilation, snapshots, Markdown-live references, script opacity, and the include/entry when: plus || limitation.

Verdict

NEEDS FIXES

Recommended Actions

1. Make matched command-file read failures fail closed instead of falling through to a lower-precedence prompt, then add an unreadable/raced-file regression.
2. Permit the valid $INPUTS.output macro in included command bodies and add ordinary-command plus loop-command regression coverage.
3. Update the stale loop-node documentation and code comments.
4. Re-run the focused suites, full workflows package, type-check/lint/format/bundle checks, and bun run validate; record the known base-only Pi gate separately if it remains.
5. Re-run the full multi-agent review before merge. Do not merge the current head.

PR Review Summary

Critical Issues (0 found)

Agent	Issue	Location
—	—	—

Important Issues (0 remaining; 4 fixed)

Agent	Resolved issue	Resolution
code-reviewer	$INPUTS.output was misclassified as a node reference in command compilation and loader validation.	Reserved macro precedence is explicit in both passes; pure-expander and real discovery coverage now exercise ordinary and loop commands.
code-reviewer	A matched unreadable command file could fall through to a lower-precedence command.	Matched-file read failures carry command/path/include/node context and fail closed.
code-reviewer	An uninspectable higher-precedence command directory could also fall through.	Only absent scopes/no match continue; non-ENOENT inspection failures become path-bearing compilation errors.
silent-failure-hunter	Present malformed compiled-loop metadata could fall back to live lookup.	Present metadata must contain exactly one string prompt or error; malformed/ambiguous values fail before provider invocation.

Suggestions (3 deferred)

Agent	Suggestion	Rationale
code-simplifier	Share output-ref and input-macro traversal.	The walkers intentionally cover different surfaces; extraction would broaden this correctness fix.
type-design-analyzer	Add central compiled-command metadata accessors.	Current discriminated union and localized casts remain understandable; no current third use requires abstraction.
code-simplifier	Normalize the optional command map once.	Negligible benefit and unrelated to correctness.

Strengths

• Hermetic validation covers canonical refs, when: shorthand, approval rejection prompts, Markdown-live refs, resolved command bodies, recursive loop scopes, and parent-id collision cases.
• Included commands preserve command-first authoring while resolving bodies at load time, binding declared inputs, and rejecting implicit caller references.
• Command lookup now preserves precedence safely: matched-file and scope-inspection failures never select a lower-precedence prompt.
• Included command-backed loops retain identity plus private compiled prompt/error metadata; interactive resume prioritizes the persisted prompt snapshot after cold rediscovery or source deletion.
• Regression coverage includes $INPUTS.output, unreadable files/directories, malformed metadata, whitespace-only loops, three-level nested loop-group composition, and real filesystem delete/rediscover/resume.
• Code, tests, errors, docs, and comments specialists all passed the final reviewed heads after their findings were addressed.

Documentation

• Ordinary runtime command loading versus included load-time compilation is documented.
• Inline and command-backed interactive loop snapshot behavior is documented.
• Named script source opacity and the distinction between include selector substitution and sub-run INPUTS_* environment delivery are documented.
• Stale workflow.with and fan_out.as reference text was corrected to match current behavior.

Validation

• include-expander.test.ts: 72 passed.
• workflow-discovery-command-scan.test.ts: 4 passed.
• loader.test.ts: 250 passed.
• dag-executor.test.ts: 453 passed.
• Full @archon/workflows package suite: passed.
• @archon/workflows type-check: passed.
• Changed production-file ESLint, repository format check, bundled-default checks, and git diff --check: passed.
• bun run validate: exits 2 at check:pi-vendor-map; the same installed Pi SDK/vendor-map drift was reproduced on clean origin/dev before this PR and the PR changes no Pi/dependency files. A later uncached root lint likewise exposed two Pi SDK-derived errors in untouched provider files; changed production files pass lint.

1. Let the refreshed GitHub Actions checks for head 02ef3a1d complete.
2. Do not merge automatically; preserve the requested user gate.
3. When integrating with fix(workflows): make Codex skill use explicit (#2498) #2533, rebase/revalidate the later PR because the branches overlap workflow docs/tests/generated defaults.
