- Job declaration order does not establish runtime ordering in GitHub Actions. This test would still pass if
detectionlost itsneeds: agentdependency, and it does not verify thatsafe_outputsis gated on successful detection, so the linked VAL-P6 invariant is not covered. Assert the dependency edges and detection-success condition instead.
agentIndex := indexInNonCommentLines(yamlOut, " agent:")
detectionIndex := indexInNonCommentLines(yamlOut, " detection:")
safeOutputsIndex := indexInNonCommentLines(yamlOut, " safe_outputs:")

- The test input grants only
contents: read, so this passes even if strict mode stops rejecting every write policy. It therefore does not cover the advertised VAL-P15 rejection behavior; compile a strict workflow that requests a write permission and require validation to fail.
yamlOut := compileFormalVALStrictWorkflow(t)
assert.Contains(t, yamlOut, "permissions: {}", "PM-01: strict-mode compiled workflows must default to top-level permissions:{}")

Rationale: Adds 15 formal security architecture validation tests. CI partially run (only copilot-reviewer check). Batch with #46421 (parser refactor — also test coverage). Review to confirm tests are meaningful before merging.

Review Summary
Three blocking issues found:
1. Unrelated production schedule change (.github/workflows/agentic-auto-upgrade.yml line 37): Cron changed from 21 3 * * 5 (Fri) to 11 4 * * 6 (Sat) with no justification in the PR description or linked issue. Revert or explicitly justify.
2. VAL-P6 tests YAML order, not execution order (TestFormalVAL_P6_DetectionJobBetweenAgentAndSafeOutputs): GitHub Actions execution order is governed by needs edges, not job position in the file. Assert needs relationships (e.g. detection needs agent, safe_outputs needs detection) to validate TD-01, not file-position indices.
3. VAL-P2 proves extraction, not pipeline order (TestFormalVAL_P2_SanitizationPipelineOrder): Calling sanitizeRunStepExpressions in isolation does not verify IS-10 ordering through the compiler. Either rename to match what is actually tested, or exercise the full compiler pipeline.
Minor observations
- VAL-P12 substantially overlaps VAL-P2; consider consolidating.
- The TLA+ sketch in the spec uses informal pseudocode syntax — label it as pseudocode.

Skills-Based Review 🧠
Applied /tdd and /grill-with-docs — requesting changes on three correctness gaps in the formal test suite.
📋 Key Themes & Highlights
Issues Found
- P6 — wrong ordering proxy (line 163):
indexInNonCommentLinesmeasures YAML text position, not GitHub Actions execution order (which isneeds:driven). The test can pass even when jobs run in the wrong sequence. → Fix: assertneeds: [agent]inside thedetectionsection instead. - P9 — regex scope ambiguity (line 196):
formalVALConcurrencyGroupmatches the firstgroup:line in the entire YAML, which may be a job-level concurrency key rather than the top-level block. → Fix: sliceyamlOutbefore\njobs:before applying the regex. - P15 — incomplete strict-mode assertion (line 265): The test only checks that activation/agent have no write perms in strict mode, but never verifies that
safe_outputsretains its write permissions. A regression that removes write fromsafe_outputsunder strict mode would go undetected. → Fix: addassert.Contains(safeOutputsSection, "issues: write", ...).
Positive Highlights
- ✅ Excellent coverage breadth: all 15 VAL-P* predicates are backed by executable tests — this is a meaningful improvement over the previous static-only spec.
- ✅ Tests follow the established
compileFormalVAL*helper pattern cleanly. - ✅ P12 table-driven subtests are well-structured with clear Arrange/Assert separation.
- ✅ P11 / P13 / P14 directly exercise production validator functions rather than mocking — correct choice.
- ✅ Spec-to-code traceability table in the markdown is a good addition.

[/tdd] P6 validates YAML declaration order, not execution order — this test can pass even when detection runs before agent at runtime.
<details>

GitHub Actions execution order is determined by needs: edges, not by where jobs appear in the YAML file. indexInNonCommentLines checks textual position only.
Replace the position-index assertions with structural checks on the compiled needs: fields:

Add a positive assertion that `safe_outputs` still has `issues: write` under strict mode, mirroring the check already in P10:

REQUEST_CHANGES — 3 blocking issues in the test suite
Three correctness problems in security_architecture_validation_formal_test.go must be fixed before merging.
Blocking issues summary
-
P6 ordering test is structurally wrong (line 161):
indexInNonCommentLineschecks YAML file order, but GHA execution order is defined byneeds:edges. The test can pass on non-compliant YAML and fail on compliant YAML — it validates the wrong property. Fix: assert onneeds:contents, not line index. -
Unchecked type assertion at line 241:
result["run"].(string)panics if sanitization ever changes therunfield type. Panics in tests are harder to diagnose than assertion failures; userequire.True(t, ok)as already done at line 115. -
Permission regex misses quoted YAML values (line 54):
formalVALWritePermissionLinewon't matchissues: "write". Tests P3, P10, and P15 could silently pass while write permissions are present in quoted form.
The cron-schedule change to agentic-auto-upgrade.yml is unrelated to this PR's stated scope and was flagged in a separate existing comment.

TestFormalVAL_P6 validates YAML position, not execution order: indexInNonCommentLines checks where jobs appear in the YAML file, but GitHub Actions execution order is governed by needs: dependencies, not line order. A compliant implementation could reorder jobs in the YAML while execution order remains correct — and vice versa, making this test a false signal in both directions.
💡 Suggested fix
Assert on needs: declarations rather than line positions:
detectionSection := extractJobSection(yamlOut, string(constants.DetectionJobName))
assert.Contains(t, detectionSection, string(constants.AgentJobName), "TD-01: detection must depend on agent")
safeOutputsSection := extractJobSection(yamlOut, string(constants.SafeOutputsJobName))
assert.Contains(t, safeOutputsSection, "- detection", "TD-01: safe_outputs must depend on detection")The existing assert.Contains check for "- detection" in the safe_outputs section (line 163) is correct; apply the same pattern to agent→detection ordering.

Unchecked type assertion panics instead of failing the test: result["run"].(string) will panic if sanitization removes or replaces the run key with a non-string value. Test panics surface as cryptic failures rather than descriptive test failures.
💡 Suggested fix
Use a guarded assertion:
runStr, ok := result["run"].(string)
require.True(t, ok, "sanitized run field must remain a string")
assert.NotContains(t, runStr, "${\{", "IS-04: run field must not retain raw expressions")This follows the same pattern already used at line 115 (runVal, ok := sanitized["run"].(string)) in TestFormalVAL_P2.

Write-permission regex won't match quoted values: formalVALWritePermissionLine matches lines like issues: write but will miss issues: "write" (YAML quoted form). If the compiler ever emits quoted permission values, TestFormalVAL_P3, P10, and P15 will silently pass while write permissions are present.
💡 Suggested fix
Either extend the regex to handle optional quotes:
formalVALWritePermissionLine = regexp.MustCompile(`(?m)^\s+[a-z0-9-]+:\s*"?write"?\s*$`)Or add an explicit test case that verifies the regex matches both issues: write and issues: "write" to document the intentional scope.
This updates the security-architecture validation doc from a static cross-reference into an executable spec/test mapping. It adds formal coverage for the lock-file conformance checks called out in the issue: job topology, sanitization ordering, permission isolation, fork guards, threat-detection placement, action pinning, timestamp validation, and concurrency constraints.
