+## Item 17 -- DOCFIX-203: mark D-134's superseded original band table in place
+
+**What:** added a `**SUPERSEDED ... do NOT use these bands**` marker immediately above the
+ORIGINAL D-134 band table in `docs/design-decisions.md` (control .10-.19 / compute .20-.49 /
+storage .201-.254), pointing at the authoritative 2026-07-23 AMENDMENT (contiguous: .4-.49
+utility, .50-.99 VIP, .100-.200 nodes, .201-.254 dynamic). Original kept as history.
+**Why:** the amendment header says it supersedes the original, but the original table carried
+NO in-place marker -- a reader grepping `D-134` hits the original first and gets the rejected
+bands. The Chat seat did exactly this 2026-07-25 (one read from a false discrepancy), and the
+band-modelling this coupling (D-136) must do reads these bands. Committee-confirmed.
+**Verify:** `awk '/## D-134:/,/## D-134 -- AMENDMENT/'` shows the marker before the first
+table row.
+**Revert:** `git revert <commit>` -- single text addition, no behavioural effect.
