   - Cost-of-change: changes here should not ripple to other files
     (if they do, the substrate is wrong — surface, do not work around)
 
+BURN-DOWN OUTPUT BAR (per docs/modeling-discipline.md — Practices 4, 7–10;
+  same numbering as that doc only; not a parallel rubric):
+  - **Practice 7 — projection, not enumeration:** derived operations (map /
+    filter / …) come from eliminators (`fold`, projections), not hand-zoos
+    of nominal one-field wrappers.
+  - **Practices 8 / 9 — fact-bundle / no-prose:** no hollow carriers;
+    deferral rationale lives in `DECISIONS.md` / ledger rows — not multi-line
+    `.dag` comment expansion.
+  - **Practice 4 — dissolution dispositions on substrate PRs:** any
+    dissolution-class surface in the diff must carry an explicit **🔴 / 🟡 /
+    🟢** disposition (shared legend in modeling-discipline) consistent with PR
+    #3244: **🟢** means *genuinely no dissolution work* (must **not** name a
+    downstream dissolve substrate in the same breath); **🟡** names the **named
+    primitive + substrate node + dissolve-on-arrival** follow-up; **🔴** fixes
+    here. (Practice 10 in that doc is the derived-operation / dissolution-
+    findings *review* class; disposition tags themselves are Practice 4.)
+  - **Manager pre-gate (burn-down lane):** before `gh pr ready`, the manager
+    reads every disposition for internal consistency; workers do not flip
+    ready on self-disposition alone.
