Two-package capability family mirroring session-persistence/: - dsh-settings: abstract Settings service — namespace registry with caller-fiber effect registrations, layered resolution (schema defaults < composition base < user document), schemastery validation, per-namespace deep-equal commit detection, and the settings/updated event. Boot/registration validation fails loud; provider publishes keep last-good per namespace. - dsh-settings-local: settings.yaml/.json provider — resolveSpec defaulting to $DSH_HOME/settings.yaml, chokidar hot reload, content-equality self-write suppression, atomic 0600 tmp+rename writes, comment-preserving YAML namespace patching. Consumers register inside ctx.inject(['settings'], …), so every composition works unchanged without a mounted provider. Real Loader + Include composition test proves cordis.yml boot and external-edit hot propagation; HMR disposal test proves registry cleanup. Both packages hold per-file 100% coverage. Doc budgets rise 1705→1710 (AGENTS.md) and 835→845 (packages/README.md): one structural line per file for the new package group.
