+# still the natural place to move when a `coreApi` bump forces the question. What
+# no longer happens is a merge full of `feat:` producing nothing.
+#
+# The number that ships is therefore the TAG, and CI writes it into the
+# `module.json` inside the bundle at assembly time. The committed `module.json` is
+# a floor and a starting point, not a record of the last release — `link` reached
+# the same arrangement with `Cargo.toml`, for the same reason: a release engine
+# that has to commit a bump back to `main` stops working the day someone protects
+# the branch, and this one is protected.
+#
+# ── The backdoor ────────────────────────────────────────────────────────────
+#
+# `workflow_dispatch` publishes on demand, for the case the rules above cannot
+# reach: `module.json` changed in a way worth shipping — a widened `coreApi`, a
+# new mount, a capability — with no releasable code behind it. Leave `version`
+# blank to bump the newest tag by `bump` (default `patch`), or name an exact
+# version to publish that. A dispatch releases even when nothing in the log is
+# releasable; that is the entire point of pressing the button.
 #
 # Re-running on a version that is already released is a no-op, so a rerun after an
