Upgrade path self-blocks across a plugin update: v0.7.1 wrote ~/.local/bin/abcd as a symlink into its own plugin root (e3696dc) with the note 're-run install from a session whose hooks have provisioned the cache to upgrade it to an owned copy'. After the plugin updated to v0.8.0 (eda67ccc), that re-run classified the symlink as symlink.foreign ('expected .../eda67ccc02eb/abcd'), unresolvable, 'ahoy refuses to clobber' — so the prescribed remedy is refused by its own predecessor's write, abcd on PATH stays at v0.7.1, and install_mode reads empty. Only a manual rm and a third install produced the owned copy. Fix: a symlink whose target is inside abcd's own plugin-cache directory (any root hash) is abcd's, not foreign — adopt and replace it; or have the first install never write the plugin-root symlink fallback at all, since it is guaranteed to go stale on the next update.

Relocated from another repository's ledger on 2026-09-15. It was captured by an ahoy install onboarding session whose working directory was a teaching-materials repository, so the finding landed where nothing could resolve or detect it: that tree has no installer, no plugin root and no ~/.local/bin surface. The id, the found_during stamp and the body are unchanged; only the ledger it sits in has moved. The store resolved correctly — it wrote to the repository it was standing in — and the reason nothing refused the write is recorded as iss-2609120511058115.

Grounds

• pursued: the prescribed re-run upgrades abcd's own superseded pin to the owned copy with no manual removal; shown wrong if a pin into an older vintage of abcd's cache is refused as foreign or left in place by ahoy install
