added group by:
- None (= ordered by folders/file name)
- Type (Folder first, then Image, Vidao, Audio, Document, etc...)
- Owner
- Size (With logarithmic groups))
- Shared date (with groups: today, last 7 days, last 30 days, then year)

//! PostgreSQL-backed implementation of `AuthorizationEngine`.
|
|
//!
|
|
//! Stores grants in `storage.access_grants` (see migration
|
|
//! `20260520000000_rebac_access_grants.sql`). Cascading is resolved at check
|
|
//! time via PostgreSQL `ltree` `@>` (ancestor-of) on `storage.folders.lpath`,
|
|
//! using the existing GiST index for O(log N) traversal.
|
|
//!
|
|
//! Owner is implicit — `storage.folders.user_id` / `storage.files.user_id`
|
|
//! are checked first via dedicated helpers; if the caller is the owner, no
|
|
//! SQL against `access_grants` happens.
|
|
//!
|
|
//! ## Lifecycle cleanup
|
|
//!
|
|
//! In v1, cleanup of grant rows when a resource or subject is permanently
|
|
//! deleted is enforced by **DB triggers** (`trg_cleanup_grants_*` in the
|
|
//! migration). The application layer does not call `revoke_all_for_*`
|
|
//! explicitly today — the triggers are the canonical path because they
|
|
//! also catch bulk SQL maintenance, admin scripts, and any code path that
|
|
//! bypasses the service layer.
|
|
//!
|
|
//! The `revoke_all_for_resource` / `revoke_all_for_subject` methods exist
|
|
//! on the trait for future use cases:
|
|
//! - **Caching** (planned) — a `CachedAuthorizationEngine` decorator needs
|
|
//! to see the invalidation event at the engine boundary, not just at the
|
|
//! SQL level. When caching lands, services will start calling these
|
|
//! methods explicitly before/around delete operations.
|
|
//! - **Alternate engines** (OpenFGA, future) — engines that don't share a
|
|
//! DB transaction with the resource table need an explicit signal to
|
|
//! delete their tuples.
