 ## Stage 7 — Extract explicit loader lifecycle phases
 
-Status: pending.
+Status: complete.
+
+Completion: `load.go` now visibly coordinates ordered phases using source assembly
+in `load_input.go`, option selection in `options.go`, and typed phase outputs and
+publication in `load_result.go`. Version checking lives in `validation.go`.
+One composition initializer covers profiles, CLI, and NoSource overrides without
+changing budgets. Diagnostics and source handoffs remain explicit, both ownership
+clones remain, and publication adds no history copies. Full offline baseline and
+race suites passed with Go 1.26.7 on Linux/amd64; lifecycle, early-stop, warning,
+precedence, provenance, callback ownership, and secret tests passed unchanged.
 
 Evidence: `loadWithSecretLookup` in [load.go](../../load.go) coordinates roughly
 200 lines of source assembly, decoding, callbacks, history, secrets, and result
