Annotated-tag pins (F8): a catalog `sha` recorded as `git rev-parse <tag>` names
the TAG object, while HEAD can only ever be the commit it points at. The scan
trust check compared HEAD against the unpeeled sha (so every tag-pinned entry
lost the reviewed-pin bypass and prompted on caution findings) and the sidecar
recorded the peeled commit, so `update_available` was true forever and every
`update` re-installed. The installer now peels the pin (`<sha>^{commit}`) for
trust, records `pin` on the catalog block only when the checkout satisfies it
(empty for an off-pin `--ref` install), and every at-pin check goes through
`at_catalog_pin(sidecar, entry_sha)` (repin, dashboard payload, TUI rows).
Re-pin consent (F10): `hermes plugins update` on a catalog install replaced the
tree without asking, even when the new pin declared new tools, hooks, Python
dependencies, host capabilities or a Desktop half. `repin_catalog_plugin` now
diffs the installed manifest against the staged clone BEFORE anything moves
(`_install_plugin_core(before_swap=...)`) and, on a widening:
- CLI: prints the delta and asks y/N (non-interactive → not applied, fail
closed); after a changed re-pin it runs the same `_run_capability_consent`
grant path as the git-pull `update`.
- `plugins.manage update` RPC and the dashboard REST route answer
`{ok: false, consent_required: true, delta, delta_lines}` with nothing
changed; a retry with `accept_capabilities: true` applies it. Desktop shows
the delta in its confirm dialog; the web dashboard uses `window.confirm`.
- Gateway contract regenerated (`accept_capabilities` param; `consent_required`,
`delta`, `delta_lines`, `error` result fields).
Catalog audit findings F8 and F10 (low severity, no issue filed).
