+# Enterprise Audit-Fix Continuation
+
+**Date:** 2026-06-11
+**Source:** `gsd-debug` followed by `gsd-audit-fix --severity all`
+**Branch:** `hardening/enterprise-audit-20260611`
+
+## Outcome
+
+The interrupted audit was resumed after scientifically reproducing and resolving the Azure Arc Bash CRLF failure.
+All remaining defensible auto-fixable findings were processed sequentially and committed atomically. No validation
+failure occurred, so the pipeline completed F-02 through F-08.
+
+## Atomic Results
+
+| ID | Finding | Commit |
+| --- | --- | --- |
+| F-02 | Enforce repository contracts and resolve Arc Bash CRLF failure | `062dfff` |
+| F-03 | Replace Bicep stubs with a secure compilable reference baseline | `4c583c6` |
+| F-04 | Replace fictional policy references and define safe rollout defaults | `8ef9375` |
+| F-05 | Define fail-closed Azure Arc dry-run onboarding contracts | `64a4f1a` |
+| F-06 | Connect assets, trust boundaries, threats, controls, and residual risk | `073fa1d` |
+| F-07 | Define evidence ownership, integrity, collection, and failure handling | `03e79e2` |
+| F-08 | Add bounded Sentinel KQL references and tuning metadata | `76076e6` |
+
+## Remaining Manual Work
+
+- Select and approve production identity, tenant hierarchy, and deployment identities.
+- Validate controls against a representative live Azure and Azure Local estate.
+- Obtain independent compliance and legal review before assurance claims.
+- Choose the production SIEM automation approval model and incident containment authority.

+## CRLF Debug Resolution
+
+`bash -n impl/hybrid/azure-arc/onboarding/arc-onboard.sh` failed because the committed CRLF line endings attached a
+carriage return to the closing brace. The repository now enforces LF for shell files, validates line endings and Bash
+syntax, and records the resolved GSD debug session in `.planning/debug/arc-onboard-crlf-bash-syntax.md`.
+
+## Validation
+
+- Repository contract validator passed.
+- Bash syntax and Azure Arc dry-run behavior passed.
+- PowerShell onboarding script parsed successfully.
+- Landing-zone Bicep compiled successfully.
+- JSON policy and Sentinel examples parsed successfully.
 - Workflow YAML parsed successfully.
-- Every third-party action reference is pinned to a 40-character commit SHA.
-- Workflows define least-privilege permissions and bounded execution.
-- Pages publishes `docs/` rather than the entire repository.
+- Markdown documentation checks passed.
+- Third-party actions are pinned to immutable SHAs.
 - `git diff --check` passed.
 
-## F-02 Failure
-
-The proposed repository-contract CI correctly exposed a pre-existing onboarding
-script failure:
-
-```text
-impl/hybrid/azure-arc/onboarding/arc-onboard.sh: line 20:
-syntax error near unexpected token `}'
-```
-
-The Bash file is committed with CRLF line endings. `bash -n` therefore fails on
-Linux. The uncommitted F-02 validator and workflow changes were reverted in full,
-and the GSD pipeline stopped before attempting subsequent findings.
-
 ## Manual-only Findings
 
 - Select production identity, tenant hierarchy, and deployment identities.
 - Validate controls against a representative live Azure and Azure Local estate.
 - Obtain independent compliance and legal review before making assurance claims.
 - Choose production SIEM automation approval and containment authority.
 
-## Recommended Next Pipeline
+## Assurance Boundary
 
-Start the next audit-fix run with the cross-platform Azure Arc onboarding script
-contract as the first finding. After it passes, reintroduce repository-contract
-validation before processing the remaining classified findings.
+No resources were deployed and no live Azure tenant was mutated. Reference artifacts require tenant-specific design,
+approvals, testing, and independent assurance before production use.
