- DAG architecture: `dag show/validate/export` (nulib/main_provisioning/dag.nu),
config loader (lib_provisioning/config/loader/dag.nu), taskserv dag-executor.
Backed by schemas/lib/dag/*.ncl; orchestrator emits NATS events via
WorkspaceComposition::into_workflow. See ADR-020, ADR-021.
- Unified Component Architecture: components/mod.nu, main_provisioning/
{components,workflow,extensions,ontoref-queries}.nu. Full workflow engine with
topological sort and NATS subject emission. Blocks A-H complete (libre-daoshi).
- Commands-registry: nulib/commands-registry.ncl (Nickel source, 314 lines) +
JSON cache at ~/.cache/provisioning/commands-registry.json rebuilt on source
change. cli/provisioning fast-path alias expansion avoids cold Nu startup.
ADDING_COMMANDS.md documents new-command workflow.
- Platform service manager: service-manager.nu (+573), startup.nu (+611),
service-check.nu (+255); autostart/bootstrap/health/target refactored.
- Nushell 0.112.2 migration: removed all try/catch and bash redirections;
external commands prefixed with ^; type signatures enforced. Driven by
scripts/refactor-try-catch{,-simplified}.nu.
- TTY stack: removed shlib/*-tty.sh; replaced by cli/tty-dispatch.sh,
tty-filter.sh, tty-commands.conf.
- New domain modules: images/ (golden image lifecycle), workspace/{state,sync}.nu,
main_provisioning/{bootstrap,cluster-deploy,fip,state}.nu, commands/{state,
build,integrations/auth,utilities/alias}.nu, platform.nu expanded (+874).
- Config loader overhaul: loader/core.nu slimmed (-759), cache/core.nu
refactored (-454), removed legacy loaders/file_loader.nu (-330).
- Thirteen new provisioning-<domain>.nu top-level modules for bash dispatcher.
- Tests: test_workspace_state.nu (+351); updates to test_oci_registry,
test_services.
- README + CHANGELOG updated.
