+### Post-scan resolution
+
+The prediction above held. GitHub flipped **alert #87 to `fixed` at 03:17:06Z**, after
+`refs/heads/main` re-analyzed at `c49fed608`. So the fix is now confirmed on both axes: the code
+is right, and the scanner agrees.
+
+One artifact to expect: `refs/pull/1959/head` will keep listing an `open` instance of #87 until
+that PR closes or its ref ages out. Anyone auditing by instance list rather than alert *state*
+will see it and reasonably ask — the alert itself reads `fixed`.
+
+**Correction to the omissions count.** I wrote "30 occurrences" of `/\/+$/` across `src/`. 30 was
+the *file* count; measured now it is **39 occurrences across 27 files**, one of which is the
+comment explaining the removal. Understating the remaining debt inside the section whose whole
+purpose is to not understate it was the wrong direction to be wrong in. Repo-wide open alerts
+have also drifted from 71 to 70 with the same rescan.
