`agenthub update-check` prints `message` as its headline, so every
plugin-cache install saw the literal "null" where the verdict belongs — and
that is the one install kind with no commit count to fall back on, so the
line carried nothing at all.
The plugin branch of getUpdatesStatus compares versions exactly like the
checkout branch does; it now builds the same four sentences from what it
already computed (newer release / newest / no local version to compare /
release lookup failed).
The nogit regression test asserted `message === null` as a proxy for "did
not fall through to the not-a-git-clone payload" — it now asserts that on
the message's content instead, which is what it always meant.
An archive-sourced marketplace entry ("source": "url" — this project's own)
makes Claude Code unpack the plugin rather than clone it, so the cache dir
has no .git. getUpdatesStatus probed for .git first and returned "not a git
clone; check for updates manually", skipping the entire release layer:
update_available stayed false however many releases were published, and
plugin_marketplace/plugin_name were never set, so POST /api/updates/apply's
plugin branch could never fire (it answered 409, claiming nothing newer was
published). The bug reads as "up to date", so it stayed invisible for as
long as the install happened to be current.
The plugin branch now runs BEFORE the .git probe and answers without git at
all: the repository URL comes from the marketplace manifest on disk
(known_marketplaces.json -> .claude-plugin/marketplace.json -> source.url,
null rather than a guessed host for a github owner/repo shorthand), and
package.json is the only local comparison signal. A failed release lookup
is reported as release_check, never as "nothing newer".
UI/CLI: the "not a git clone" note is gated on install_kind !== "plugin", so
the Update now button is offered where the dashboard can actually check and
apply.
