The pre-commit name guard prints its inherited-store notice three times per commit from a linked worktree. The committed .githooks/pre-commit announces the itd-150 fallback once per run, at a single site ("pre-commit: abcd name-guard: inheriting the primary checkout's <store>" on stderr), so three copies on one commit mean the hook body ran three times for that commit, which points at the dispatch (the global hooks dispatcher plus the repo hook, or a pre-merge-commit run) rather than at the notice itself. Relayed from the Gropius managed-repo session gropiusllm-56 on 2026-09-18 at v0.9.0, which called it cosmetic. Recorded because the repetition is also a measurement: if the guard runs three times, the scan costs three times what it should, and one run is the one whose refusal counts. Wanted: establish which invocations produce the three runs and either de-duplicate the dispatch or print the notice once per commit.

Grounds

• pursued: a clean commit from a linked worktree prints exactly one name-guard notice line naming each store's format, count and an inherited store's location; a second notice line from any store layout would show it wrong
