+
+# CTO First Real Governed Workflow Pass Evidence
+
+Local planning SOT only. Not a Core Protocol. Not active Core authority.
+
+## Result
+
+Status: validated.
+
+Work item: `CTO-WORK-049`
+
+Approved target:
+
+```text
+/home/svrnty/workspaces/cortex-os/cto-stage5-target-sandbox
+```
+
+Approved task:
+
+```text
+src/strings.py slugify alignment task
+```
+
+Target commit:
+
+```text
+7706f99 fix(strings): align src.slugify with root behavior, add whitespace tests
+```
+
+Harness pass report:
+
+```text
+/home/svrnty/.hermes/profiles/cto-planb/harness-runs/20260601T105222Z-r1-src-string-slugify-180161/report.json
+```
+
+Stage 5 proof:
+
+```text
+/home/svrnty/.hermes/profiles/cto-planb/harness-runs/20260601T105222Z-r1-src-string-slugify-180161/stage5-owned-repo-proof.json
+```
+
+Hermes fix commit:
+
+```text
+9806400 Fix Case Stage 5 baseline supervisor
+```
+
+## Evidence Facts
+
+- target repository admission status: `admitted`
+- target repository start clean: true
+- target repository ending clean: true
+- Case process started: true
+- changed files: `src/strings.py`, `test_strings.py`
+- allowed paths passed: true
+- forbidden paths passed: true
+- forbidden actions attempted: false
+- public publication attempted: false
+- push, merge, deploy, close, PR open attempted: false
+- validation command: `python3 -m pytest -q`
+- validation passed: true
+- operator outcome: `accepted`
+- runtime default activation: false
+
+## Root Cause Fixed
+
+The Stage 5 lifecycle supervisor previously treated any repository with more than one commit as ready to stop Case after a clean commit state. The owned Stage 5 target already had history, so the supervisor killed Case before the approved task diff existed.
+
+Hermes now passes the captured baseline HEAD into the Case engine and stops only after `HEAD != baseline_head` with a clean worktree.
+
+The Stage 5 validator now uses a target repository with existing history so this failure class is covered.
+
+## Decision
+
+`CTO-WORK-049` is validated as the first real governed workflow execution.
+
+Case remains a gated adapter behind CTO Harness.
+
+Runtime default activation remains false.
+
+This evidence does not promote CTO artifacts into Core and does not authorize broader target mutation.
