 ## Changelog
 
+### docs — the workflow moved to DooPlex-local execution (2026-07-19)
+
+**Docs only, no version bump, no code change.** Claude Code now runs on DooPlex
+(192.168.0.180, Debian 13, `kisfenyo`) instead of the Windows workstation, working directly in
+`/mnt/5_hdd/felhom.eu/git/felhom-controller`. Builds are local commands; felhom-pve is one SSH hop.
+
+- `CLAUDE.md` — environment/access table rewritten (local DooPlex + `ssh felhom-pve`, no `$SSH`
+  variable), build/deploy commands de-SSH'd, workspace-root pointer now
+  `/mnt/5_hdd/felhom.eu/git/CLAUDE.md`.
+- **New clean-tree gate** in the build section: `git status --porcelain` empty AND `HEAD` ==
+  `origin/main` before any build — because the CC working tree IS the tree `build.sh` builds from.
+  An unpushed change does not exist.
+- `claude-in-chrome` is **not available** on DooPlex — endpoint-level validation ("invoke the exact
+  endpoint the UI invokes") is now the stated standard method; strict UI coverage is a manual pass.
+- Windows knowledge is preserved, not deleted: a "Legacy: Windows workstation" note in `CLAUDE.md`
+  and `RUNBOOK-e2e-live-drive.md`, and `docs/vscode-ssh-fix.md` carries a LEGACY banner.
+
+Historical Windows references in past CHANGELOG/REPORT entries are left untouched — history is
+history. Platform-genuine mentions (the `_other.go` dev stubs, `\\FELHOM` shares in Windows
+Explorer, the Windows-grep multibyte rationale in the gate scripts) are unchanged.

 ### v0.147.3 — 4c follow-up 3: the run does not end with the last app (2026-07-19)
 
 Third real run, third thing only a live run could show. The per-app legs finished in ~15 seconds;
