-- Make the one semantic change this feature cannot express an owner's decision instead of a default.
--
-- Before the Custom role, a Manager who reached every collection through an organization-local group
-- with `access_all` held that authority *while* the group relationship lasted. It ended when the
-- group was deleted, when its `accessAll` was switched off, when the member left it, and it was inert
-- whenever `ORG_GROUPS_ENABLED` was false. Nothing in the new model expresses a permission bound to a
-- group like that: `edit_any_collection` and `delete_any_collection` live on the membership.
--
-- So the earlier migrations in this chain write the authority onto the membership, and the result is
-- deliberately not identical to what it replaces:
--
--   * it no longer lapses when the last qualifying group disappears, or when `accessAll` is cleared;
--   * it applies even with the groups feature switched off;
--   * `edit_any_collection` additionally satisfies `has_full_access()`, so the member reaches every
--     collection of the organization directly rather than through the group.
--
-- Materializing it silently would be a migration that grants durable organization-wide collection
-- edit and delete on its own authority. Dropping it silently would take a capability away. Neither is
-- ours to choose, so this migration stops and hands the decision to an owner. It grants nothing and
-- revokes nothing itself.
--
-- On a database with no Custom membership that both has edit/delete authority and belongs to an
-- organization-local `access_all` group, there is nothing to decide and this is a no-op.
--
-- Vaultwarden's startup preflight looks ahead for exactly the condition below and refuses with the
-- full text (`RefuseUnconfirmedPermanentCollectionAuthority` in `src/db/mod.rs`), from the legacy
-- schema as well, so an operator normally never reaches the abort here. Diesel reports only the
-- driver error, so on this path the question would arrive as `UNIQUE constraint failed:
-- __vw_permanent_authority_guard.blocked` and nothing else. Keep the two predicates identical.
--
-- Review the affected memberships:
--
--     SELECT uo.uuid, uo.user_uuid, uo.org_uuid, uo.status,
--            uo.create_new_collections, uo.edit_any_collection, uo.delete_any_collection,
--            (uo.uuid IN (SELECT users_organizations_uuid FROM __vw_custom_role_legacy_manager))
--                AS was_legacy_manager
--     FROM users_organizations uo
--     WHERE uo.atype = 4
--       AND (uo.edit_any_collection = 1 OR uo.delete_any_collection = 1)
--       AND EXISTS (
--         SELECT 1 FROM groups_users gu
--         INNER JOIN "groups" g ON g.uuid = gu.groups_uuid
--         WHERE gu.users_organizations_uuid = uo.uuid
--           AND g.organizations_uuid = uo.org_uuid
--           AND g.access_all = 1);
--
-- Reading the result:
--
--   * `was_legacy_manager = 1` -- a converted Manager. Review it even when
--     `create_new_collections = 1`: that independent permission can be changed after an earlier
--     revision materialized group-derived edit/delete, so its current value cannot prove where those
--     two permissions came from. A membership whose own legacy `access_all` supplied all three may
--     therefore be listed conservatively even though its authority was already permanent.
--   * `was_legacy_manager = 0` -- never a Manager. On a database first upgraded by revision bf54088c
--     they may carry permissions that revision's 2026-08-09-120000 granted in bulk, which nothing can
--     distinguish from a deliberate grant any more -- check them against what you intended.
--
-- An invited or revoked membership is listed too, and deliberately so. It holds no authority today --
-- every guard requires a confirmed membership, and `MembershipStatus::from_i32` rejects the revoked
-- value outright -- but the permission is what it would come back with if it is ever restored, and
-- by then the group it came from may be gone. Status is therefore not part of the predicate.
--
-- Clear whatever you do not want to keep, for example:
--
--     UPDATE users_organizations
--     SET edit_any_collection = 0, delete_any_collection = 0
--     WHERE uuid = '<MEMBERSHIP_UUID>';
--
-- Then record the decision once, with every Vaultwarden instance stopped:
--
--     CREATE TABLE __vw_ack_permanent_collection_authority (acknowledged INTEGER NOT NULL PRIMARY KEY);
--
-- The acknowledgement is consumed at the end of this file, so one decision covers one upgrade.
--
-- The legacy-Manager record has to exist already: the chain and supported rollback use it as the
-- immutable role-provenance record. Refuse a damaged history here too; see 2026-07-23-120000 for why
-- this never creates it.
--
-- The duplicate key aborts the migration. It is only inserted while the record table is absent.
