 ## Stage 12 — Compose the Final CLI Run Lifecycle
 
+**Completed 2026-09-24.** CLI processing now inspects settings and profiles,
+preflights and initializes required outputs before input/model work, creates
+debug evidence only when selected, runs the fixed-chunk runner with caller
+context, and finalizes transcript/reports in order. Failed processing and output
+writes produce failed-status reports from available partial state; successful
+stderr begins with the shared correction/error/recovery counts. The duplicate
+CLI chunking pass and old JSON report flow are removed. Subprocess tests cover
+file/stdout destinations, disabled reports, debug-only runs and optional debug
+failure, total model failure, partial validation and later work, invalid input
+after initialization, and pre-dispatch output failures. Focused package tests
+and `git diff --check` passed; `go test ./...` passed before the last small
+integration assertions were added and will be rerun in Stage 14.

 **Work:** Replace the current monolithic process/report/retention flow with the
 final composition: load/inspect settings, resolve and initialize required outputs,
 optionally initialize debug, load/normalize input, run fixed-chunk processing,
