gates / gates (push) Successful in 18s
R-840: the config bundle — a signed agent_config_update brings a box's root-owned files (sudoers, wrappers, units)
felhom-os-apply gains mode 'bundle' (signed, verified by the wrapper itself against the root-owned
signers file — or, when that file is missing, only the installer's pinned key, which it then creates)
and --install-bundle (the installer's root entry). BUNDLE_FILES is the one table of paths; every check
(visudo, sh/bash -n, python, unit sections, RuntimeDirectory guard, nft -c, the route itself) runs
before the first write; a failed write or self-check puts every previous copy back. The trust root is
never a bundle path (R17). scripts/build-config-bundle.py builds it reproducibly; release-agent.sh
publishes it beside the binary. The agent reports the bundle record in system.config_bundle.
felhom-opsign signs agent_config_update. 43 wrapper tests (22 mutants red), Go executor tests.

"""Tests for the config bundle (R-840, `11` §5.4.2): felhom-os-apply's `bundle` mode and `--install-bundle`, and
scripts/build-config-bundle.py. An in-memory host plays the files; nothing real is written or run. Each refusal has a
test; each test names the rule it pins. Red-proof: `audits/r840-config-bundle-2026-10-04/partB/redproof.txt`.
Run: python3 configs/test_felhom_config_bundle.py (also run by internal/osupdate's Go test)
