+## v0.143.0 — the config bundle: a signed route for a box's root-owned files (R-840, decision 96) (2026-10-04)
+
+Released by `scripts/release-agent.sh`: binary sha256 `41c0d3060013dfda795262147454248149bee0888c0935170fdb85de6e7a35da`,
+config bundle `felhom-config-bundle.json` sha256 `8d7273cf5313ef62b867cb6f831c631923a436452d6f90b8ff7f0771170396ba`.
+
+- **The bundle.** Every root-owned file the installer's step 5 writes (sudoers ×2, the five wrappers, the crash guard
+  and its units, the agent and rollback units, the start-limit drop-in, the mgmt watchdog, the OOB belt's files) as ONE
+  reproducible JSON file, built by `scripts/build-config-bundle.py` from `BUNDLE_FILES` in `configs/felhom-os-apply`
+  (one table) and published beside the binary. The installer (1.31.0) installs the same file.
+- **The route.** A signed `agent_config_update` {agent_version, bundle_sha256} (`felhom-opsign -op agent_config_update
+  -bundle-sha256 …`). The agent is the courier (downloads, checks the sha, hands over); `felhom-os-apply` mode `bundle`
+  verifies it ITSELF: the operator signature against the root-owned `/etc/felhom/operator-signers` (or, when that file
+  is missing, ONLY the installer's pinned key, after which it creates the file with exactly that key), the host binding,
+  the window, its own nonce; the bundle sha; every path in `BUNDLE_FILES` (R16) and never a trust file (R17); every
+  content check before the first write (visudo, sh/bash -n, python, unit sections, the RuntimeDirectory guard, User=,
+  nft -c, and that the route itself survives). Atomic per file, previous copies kept under
+  `/var/lib/felhom-os-apply/bundle-prev/`; a self-check after (visudo -c, `sudo -l` lists the route, the new wrapper's
+  `--self-check`, the self-update wrapper's usage, the crash guard's status = kernel.panic); any failure puts every
+  previous copy back. A newly installed crash guard is started (`enable --now`: kernel.panic for this boot, no reboot).
+  Record `/etc/felhom/config-bundle.json`; the agent reports it as `system.config_bundle`, the facts mode adds drift.
+- **Bootstrap.** A box whose `felhom-os-apply` predates 0.143.0 cannot take the first bundle by the route (nothing on it
+  can write a root file from a signed job): `felhom.eu/scripts/felhom-bundle-bootstrap.sh` is the one by-hand step.
+- **`build-golden.sh` 3.2.0** (not part of the binary): `GOLDEN_GUEST_PKGS` brings the template to exactly the
+  approved guest release (only installed packages, never newer, never a removal or a new package) and prints the
+  first-night count.
+- Tests: `configs/test_felhom_config_bundle.py` (43; 22 of 22 mutants red), `internal/osupdate/bundle_test.go`,
+  `internal/hub/bundle_record_test.go`. Live: `felhom.eu/documentation/audits/r840-config-bundle-2026-10-04/partB/`.
+
 ## v0.142.1 — a Docker step no longer leaves the controller and traefik blind (R-858, `09` decision 95)
 
 > **RELEASED 2026-10-04** by `scripts/release-agent.sh` — tag `v0.142.1` (`4950030`), sha256
