Remove concurrency.limit from the recipe-ci pipeline (.drone.yml): it duplicated
DRONE_RUNNER_CAPACITY (nix/modules/drone-runner.nix maxTests) and the two had to be kept in
step by hand (docs/concurrency.md §8.6). maxTests comment updated to state it is the single
knob and to describe the new safety model.
flake.nix/flake.lock STAY at root so the build ref #cc-ci is unchanged; only flake's internal
configuration.nix path updated. Root-relative refs inside moved modules re-based ../X -> ../../X
(secrets/bridge/dashboard); configuration.nix's ../../modules imports unchanged (both dirs under nix/).
Living docs (README, architecture/install/secrets/enroll) + .drone.yml comment updated to nix/...;
append-only history logs left as-is. DECISIONS.md records RL5 + the deferred-coordinated RL6.
Verified on cc-ci: nixos-rebuild build 'path:#cc-ci' -> toplevel 8i3jcad9 (BYTE-IDENTICAL to the
pre-move build — store derivations are content-addressed on file contents, module .nix not in the
runtime closure); scripts/lint.sh -> lint: PASS.
