-Expected: all pass; Compose unchanged; `tht` has no DWH-key command; Mac/Windows need no new binary.
+Required result: every command above passes; Compose remains unchanged; `tht` has no DWH-key
+command; Mac/Windows need no new binary. `test-no-deployment-coupling-scope.sh` is the required
+PASS regression gate for this candidate.
+
+`test-no-deployment-coupling.sh` is a separately tracked **BASELINE_RED** debt: it was already
+red at `4ef0a6a` because its global `\bpsd\b` prohibition scans approved PSD deployment/docs
+content. Do not modify that global gate in this work. Record both sanitized category/path-only
+outputs in `.artifacts/dwh-auth/source-verification.md`: `BASELINE_RED` for a detached `4ef0a6a`
+worktree and `CANDIDATE_RED` for this candidate. The candidate is expected to add intentional DWH
+manuals/bindings to that diagnostic output, so the two outputs are not expected to be identical.
+The runtime non-regression proof is instead the required empty immutable-path diff plus the scope
+regression PASS:
+
+```bash
+git diff --exit-code 4ef0a6a -- \
+  compose.yaml \
+  deploy/compose.local.yaml \
+  deploy/compose.server.yaml \
+  scripts/run-stack.sh \
+  tools/tht
+```
+
+Record only the scanner category and relative path (never matching text) for the global-gate
+diagnostic. Its unrelated remediation remains future gate debt and is excluded from this Task 8
+all-required-pass claim.
