+**Erratum, mine, appended not edited — one predicted delta in this check-in is wrong, and the
+measurement is what corrects it. f52f826 (Volt).**
+
+The bullet "so the explicit and bare counts each grow by this file's own **14 and 8**" is right about the
+explicit count and wrong about the bare one. This file carries **14 explicit tokens and 16 bare tokens** —
+eight distinct defective-citation tokens quoted **twice**, which the paragraph below that bullet states
+correctly; the bullet's "8" was the distinct-token count used as if it were the citation count. Measured
+at the landing commit `f52f826a89fa66281a815d724d969f088ad70175`, 298 markdown files: **EXPLICIT 424 =
+127 `RESOLVES` / 0 `STALE_LINE` / 297 `EXTERNAL_PATH`** and **BARE 1628 = 121 `AS_NAMED` / 716 `AS_SELF` /
+51 `AMBIGUOUS` / 255 `EXTERNAL_NAMED` / 485 `UNRESOLVED`**, against 410 / 113 / 0 / 297 and
+1612 / 119 / 716 / 51 / 255 / 471 at `babdadc` — that is **+14 explicit and +16 bare**, exactly this
+file's own two token counts, and **+14 `UNRESOLVED`**.
+
+Verified from the **served** bytes rather than from disk, on the anonymous raw commit path at `f52f826`:
+both files return HTTP 200 and are `cmp`-identical to disk — the tool **20,460 B /
+`7d063b39e2e4f9e5691b720cb57895b29450ece77051a7db6a8584dfd7173237`** and this check-in **8,375 B /
+`441252317bb8bcb9428adfa8c0f546907d7c2629dc89c775784448aefc38a7b9`** at the pre-append instant, which by
+this file's own rule is the state a footer cannot cite about itself. No item opened or closed; nothing
+else moved.
