// Package workflow_test encodes the formal predicates derived from
// specs/security-architecture-spec-validation.md, §12 Compliance Test Matrix
// Gap Analysis, Permission Management row (T-PM-001 to T-PM-007).
//
// This suite specifically closes the previously identified evidence gaps:
// - T-PM-003 (strict mode gating of workflow_run branch-restriction warnings/errors)
// - T-PM-005 (repository validation guard for workflow_run triggers)
// - T-PM-007 (GitHub token precedence/validation for tool vs. safe-output jobs)
//
// Predicates encoded (see issue body "Formal Model" section for full notation):
// P1 WorkflowRunRepoSafetyCondition
// P2 WorkflowRunRepoSafetyOnlyAppliesWhenTriggerPresent
// P3 WorkflowRunRequiresNonEmptyWorkflowsField
// P4 WorkflowRunBranchRestrictionModeSensitive (T-PM-003)
// P5 WorkflowRunBranchRestrictionSatisfiedNoOp
// P6 NoWorkflowRunTriggerIsNoOp
// P7 DefaultGitHubTokenPrecedence (T-PM-007)
// P8 SafeOutputGitHubTokenPrecedence (T-PM-007)
// P9 TokenChainsAreDistinctByJobRole (T-PM-007)
// P10 StrictModeIsPerCompilerInstance (T-PM-003)
// P11 BashRestrictionWildcardSafe (supporting engine-capability gate)

Summary
Formalized
specs/security-architecture-spec-validation.md, focusing this run on the §12 Compliance Test Matrix Gap Analysis for Permission Management (T-PM-001 to T-PM-007). Prior notes flagged T-PM-003 (strict mode), T-PM-005 (workflow_runrepository validation), and T-PM-007 (token validation) as lacking dedicated evidence entries. This run derives formal predicates directly from the real exported implementation (buildWorkflowRunRepoSafetyCondition,validateWorkflowRunBranches,Compiler.strictMode/SetStrictMode,getEffectiveGitHubToken,getEffectiveSafeOutputGitHubToken) and produces a testify suite encoding acceptance/rejection boundaries for each.Specification
