+**SOURCE STATUS (verified 2026-09-17, standards#645 + PR #835):** the scaffold
+hunt is resolved — every candidate was checked before touching anything.
+
+* rsr-template-repo: flipped on 2026-05-22 (`04997b9`, "chore: migrate license
+  from PMPL-1.0-or-later to MPL-2.0") — THREE MONTHS before the residue was
+  measured; today's residue was minted from the older vintage (`2283f12`).
+* scaffoldia: NOT an emitter — its 7 PMPL hits are all
+  `machine-readable-design/harvested-registry/**.ncl` package-registry DATA
+  records; editing them would falsify harvested facts.
+* llm-warmup-* templates: 404, gone — cannot emit.
+* standards-side remnant (a second, dormant vector): the v1
+  `STATE.a2ml.template:46` comment literally told mints "Almost always
+  PMPL-1.0-or-later" while shipping `license = "MPL-2.0"`. Fixed at source
+  (PR #835, merged 2026-09-17).
+* axel-protocol's three `trust.txt` copies: VERIFIED AUTHORED and consistent
+  (six normative PMPL declarations in the same directory) — leave, exactly as
+  §3 says, and reconcile at the corpus level when axel-protocol's own licence
+  story is settled.
+
+So: every emitter is now either fixed, extinct, or excluded. Under the §7a
+strategy the remaining work is the §1/§3-excluding re-propagation + residue
+clean — which is owner-run, exactly as planned.

 === 7b. Banned `MPL-2.0-or-later` → `MPL-2.0` — **25 matches**
 Estate policy is `MPL-2.0` (never `-or-later`). The 25 hits concentrate in
 delicate areas: the `standards` RSR *satellites* (`…/satellites/palimpsest-license/…`,
