Summary

  • Confirm action names from transitive literal top-level includes before reporting undefined-action warnings. Keep warnings for dynamic, missing, or unreadable includes.
  • Count expect subjects and expected expressions as variable uses.
  • Add CLI regression tests and document the analyzer behavior.

Verification

  • Red-first regression commit bb103dae: two new cases failed before the fix.
  • cargo fmt --all -- --check
  • cargo clippy --all-targets --all-features -- -D warnings
  • cargo test --all
  • With the patched WFL binary and the companion Logbie-web cleanup, all seven Logbie-web WFL suites passed (89 tests) with zero ANALYZE-SEMANTIC or ANALYZE-UNUSED warnings. The original run produced 442 warnings.

Companion change: Logbie-web test cleanup on codex/cleanup-wfl-test-bindings.


Devin Review

Summary by CodeRabbit

  • Improvements
    • Static analysis now recognizes actions defined in literal includes, including transitive includes, when checking for undefined-action warnings. An action is recognized only if its include is reached before the call; dynamic includes and unresolved action names can still produce warnings.
    • Variables used in expect assertions—including values accessed through properties or methods—are now recognized as used, reducing unused-variable warnings.
  • Documentation
    • Clarified how included actions are checked and when undefined-action warnings may appear.

📝 Walkthrough

Walkthrough

The analyzer now records undefined-action call sites and recognizes variables used in expect assertions. The CLI scans transitive literal includes and suppresses matching warnings according to include order. Tests and documentation cover these changes.

Changes

Analyzer warning corrections

Layer / File(s) Summary
Resolve actions from literal includes
src/analyzer/mod.rs, src/main.rs, tests/analyzer_include_expect_test.rs, Docs/04-advanced-features/modules.md, History/dev-diary/2026/2026-09-25-included-actions-and-expect-uses.md
The analyzer records undefined-action call sites and statement positions. The CLI scans transitive literal includes and suppresses matching warnings only when include order permits. Scan allowance exhaustion retains unresolved warnings; deadline or cancellation failures propagate as errors. Tests and documentation cover include ordering, dynamic includes, and scan budgets.
Track variables used in expect assertions
src/analyzer/static_analyzer.rs, tests/analyzer_include_expect_test.rs
The unused-variable analysis counts assertion subjects, expression operands, property receivers, and method receivers and arguments as uses. Tests check these uses and confirm that unrelated unused variables are reported.

Priority: ⬇️ Low

Change: Bug fix

Merge Risk: ⚪ Minimal · up to c47b2

No merge-blocking issue remains; the reviewed include and assertion-warning changes are ready for normal merge checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to c47b2

The CLI already read literal include files while checking undefined-action warnings. This change narrows when warnings are suppressed and keeps the include scan bounded, but the privileges and isolation of deployments running the CLI are unknown.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — A caller supplying source with literal includes can cause diagnostic reads of files accessible to the CLI process. The inspected change does not establish a newly reachable filesystem scope relative to the prior scanner; the effective scope depends on process privileges and external confinement.

Trust Boundaries and Controls

  • observed — The diagnostic scan skips unreadable, oversized, invalid, or unparseable includes and checks import depth. Runtime inclusion separately analyzes and type-checks included programs before execution; suppressing a warning does not itself execute an include.

Resilience and Maintainability Implications

  • observed — The scan now has its own bounded operation allowance rather than spending the run's operation allowance; cancellation and deadline failures from the run still propagate. This can permit more diagnostic work than the former shared-budget arrangement.

Hardening Proposals

  • proposed — If untrusted programs are analyzed by a privileged service, confine the CLI's filesystem access to the intended source tree or sandbox the process. The inspected code does not establish that such a deployment exists.

In `@Docs/04-advanced-features/modules.md`:
- Around line 154-155: Update the “Calling actions from an included file”
paragraph to explain that literal includes and their transitive literal includes
are checked for action names, and that unresolved names may produce a non-fatal
warning without guaranteeing runtime resolution. Move the existing
literal-include paragraph from the type-checking section to follow this
statement, and keep the “Type checking warnings in included file” example
directly after the type-checking paragraph.

In `@src/analyzer/static_analyzer.rs`:
- Line 1310: Update the shared mark_used_in_expression walker to traverse the
receiver/object of MethodCall and PropertyAccess expressions, so variables used
as assertion subjects are marked as used. Add a regression test for an assertion
whose subject is a method call or property access on a variable.

In `@src/main.rs`:
- Around line 327-333: Update the `literal_include_actions` error branch to
print the budget-breach message with the standard Error prefix and exit with
status 2, rather than adding it to diagnostics and returning. Preserve the
successful action flow.

Adds failing regressions for PR #747 review findings:
- a call that runs before its literal include must keep its warning
- an action body that can run before the include must keep its warning
- the include scan must not spend the run's operation budget
- an exhausted scan must not report a budget failure
- a deadline breach during the scan must surface as a budget failure
- expect subjects using property/method access count as variable uses
The CLI helper now asserts exit status alongside diagnostics.

Addresses PR #747 review findings:
- Keep an undefined-action warning unless the literal include that defines
  the action has run by the time the call runs. The analyzer now records the
  top-level statement holding each include-relaxed warning; the CLI compares
  statement positions. Calls in action/container/handler bodies count as run
  only after their definition, when a later statement can invoke them.
- Give the include scan its own operation allowance (same ceiling, the run's
  remaining time) so it cannot spend the program's max_operations. Running
  out stops the scan and keeps warnings; a run deadline or cancellation during
  the scan exits 2 with an Error line like other front-end budget breaches.
- Count property-access and method-call receivers (and method arguments) as
  variable uses in the unused-variable walker.
- Reconcile the module guide's include-warning paragraphs and extend the
  dev diary entry.
