 ## Details
 
+### 62. Delete a group's grants and its membership set in one Keto transaction, so a failure cannot leave it half-deleted.
+
+`groupsDelete` in `examples/plugins/auth-admin/admin-groups.ts` drops each held grant with its own
+`deleteTuple`, then the membership tuple, so a Keto failure part-way leaves a group with some grants
+gone and its members still listed. Send all the deletes through `KetoClient.transactTuples`, as
+`applyGrants` in `admin-grants.ts` does. The comment on delete order stays true inside one
+transaction.

+### 69. Rename `views/index.ejs` to `views/dashboard.ejs`, so the core view's file names the page it renders.
+
+`index.ejs` renders `/dashboard` (`src/http/app.ts` ~L168); `home.ejs` renders `/` and matches the
+manifest's `home` slot, so it keeps its name. Core `views/` is an `include()` root for plugin views
+(`src/plugin-host/view-resolver.ts`), so a plugin may include `index` today: the rename changes the
+contract surface (AGENTS.md → Rules) and ships in a minor. Update `docs/reading-cost.md` and the
+README file map. Make `views/index.ejs` easier to find, a place the seats found hard.

+### 64. Keep the permissions section on the user form when a self-deactivate or self-delete is refused.
+
+In `examples/plugins/auth-admin/admin-users.ts`, the self-refusals in `usersState` (~L405),
+`usersDeleteConfirm` (~L415) and `usersDelete` (~L429) call `formResult` without
+`...(await pickerOrNothing(deps, id))` or `canWrite`, so the re-rendered form loses its permissions
+section; `usersUpdate` and `usersRecovery` keep it, and `pickerOrNothing`'s comment promises it.
+The groups side re-renders through `groupDetailPage`, which keeps it. Make `usersPermissions` and
+the `pickerOrNothing` contract easier to read, a place the seats found hard. Not exempt: a
+comprehension finding, not a 🔴, and no maintain goal is broken.

-### 71. Delete, with a group, every membership tuple in another group that names it, so re-creating the name restores no nested membership.

-Groups nest: a parent holds `Group:<parent>#members` with `subject_set` `Group:<child>#members`.
-`groupsDelete` in `examples/plugins/auth-admin/admin-groups.ts` drops the child's own member tuples
