- A1: delete STEP 5d (graphify --mode quick doesn't exist in the CLI; the
command always failed, masked by `|| true` — STEP 10's full pass already
covers the graph)
- A2: STEP 10 full-pass build flag --output -> --out
- A8: pipeline is 12 steps (STEP 0-11), not 11; header template unchanged
(N/11 correctly denotes the max index of a 0-indexed 12-step sequence)
