+# Withdraw versions of `@orcarouter/code-review` from npm, by hand, on purpose.
+#
+# This is a demolition tool. It exists because npm's unpublish window is 72
+# hours and the credential that can use it is the `NPM_TOKEN` repository secret
+# — not something on any maintainer's laptop. Running it from CI keeps the token
+# where it already lives and leaves a run log of who withdrew what.
+#
+# An unpublish CANNOT be undone: the version number is burned forever, and
+# anyone who pinned it gets an E404 rather than a warning. Prefer
+# `npm deprecate`, which leaves the tarball installable and prints a warning.
+# Reach for this only for a version that is days old with no known consumers.
+#
+# Two guards, because the failure mode is deleting the live release:
+#
+#   1. `confirm` must be typed as the exact word "unpublish". A dispatch button
+#      is one click and this workflow's blast radius is the whole package.
+#   2. The version in `package.json` on the default branch is refused. That is
+#      what `dist-tags.latest` points at and what every `npx` resolves; the job
+#      fails before touching the registry rather than after.
+#
+# Order matters when withdrawing a run of versions: list DEPENDENTS FIRST. Up to
+# 1.5.0 this package declared a dependency on ITSELF at ^1.0.2, and npm reads
+# dependents when deciding whether a version may go.
+#
+# Inputs reach the shell through `env`, never through `${{ }}` inside a `run`
+# block — an interpolated dispatch input is a command-injection hole, and this
+# job holds a publish token.

+#### The `1.x` line was withdrawn; `2.0.0` is the floor
+
+`@orcarouter/code-review` starts at **2.0.0** on the registry. 1.0.2 through
+1.5.0 were published on 25–26 Aug 2026 and unpublished inside npm's 72-hour
+window, so the packument shows one version and its history looks truncated —
+it is not. What went with them:
+
+- **App mode.** Up to 1.4.0 the skill offered a GitHub App install as an
+  alternative to the Action. Installing an App is a permission grant only a
+  human can approve on a web page, so the agent could only hand over a link;
+  1.5.0 dropped it and 2.0.0 is the first version published without it. The
+  major marks that break rather than leaving it in a minor nobody can install.
+- **The self-dependency.** 1.1.0 through 1.5.0 declared
+  `@orcarouter/code-review: ^1.0.2` as a dependency *of itself*, so every
+  `npx` pulled a second, older copy of the CLI. Removed in 2.0.0 and pinned by
+  a test — see "the CLI ships with no dependencies" in
+  `scripts/installer.test.mjs`.
+
+Unpublishing was the right call only because the line was two days old with no
+known consumers. It is not the default: outside the 72-hour window npm refuses,
+a withdrawn number can never be reused, and anyone pinned to it breaks with an
+E404 rather than a warning. **Deprecate instead** — see below.
