What step 5 is actually doing
Goal: stop writing to storage.files.user_id / storage.folders.user_id on new INSERTs. This is a prerequisite for step 6 (dropping the column entirely). The column has existed since the pre-D0 single-owner era; every read that used to key on it has already been migrated to drive-membership grants over the last N days.
What has to change together for this to be safe:
┌──────────────┬─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┬───────────────────────────────────────────────────────────────────────────────────────────────────────┐
│ Piece │ What changes │ Why │
├──────────────┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┼───────────────────────────────────────────────────────────────────────────────────────────────────────┤
│ Migration │ Swap storage.files uniqueness indexes from (folder_id, name, user_id) to (drive_id, folder_id, name) │ Otherwise, two new rows with user_id = NULL would both be allowed (PG treats NULLs as distinct) — │
│ (a) │ │ uniqueness silently breaks │
├──────────────┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┼───────────────────────────────────────────────────────────────────────────────────────────────────────┤
│ Migration │ ALTER user_id DROP NOT NULL on both tables │ Otherwise, dropping the INSERT bind violates NOT NULL and every write 500s │
│ (b) │ │ │
├──────────────┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┼───────────────────────────────────────────────────────────────────────────────────────────────────────┤
│ Migration │ Drop dead user_id-leading indexes │ Cheap cleanup — nothing scans them anymore │
│ (c) │ │ │
├──────────────┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┼───────────────────────────────────────────────────────────────────────────────────────────────────────┤
│ PL/pgSQL (d) │ Rewrite storage.copy_folder_tree without user_id in the INSERT column list │ Cross-drive copy runs entirely in SQL, needs the same treatment │
├──────────────┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┼───────────────────────────────────────────────────────────────────────────────────────────────────────┤
│ Rust (e) │ ~12 INSERT column-list drops across folder_db_repository, file_blob_write_repository, drive_pg_repository, dedup_service, │ Actual write path │
│ │ folder_service, load-seed.rs │ │
├──────────────┼─────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────┼───────────────────────────────────────────────────────────────────────────────────────────────────────┤
│ Rust (f) │ Simplify folder_db_repository::create_folder's parent lookup to only fetch drive_id (was fetching (user_id, drive_id)) │ It's fetching a value it no longer needs │

```
- Add utoipa v5 dependency with ToSchema derives on all REST API DTOs
- Annotate free-function handlers with #[utoipa::path] (trash, share, favorites, recent)
- Create ApiDoc struct with OpenApi derive registering 37 schemas across 7 tags
- Add generate-openapi binary outputting resources/gen/openapi.json
- Serve OpenAPI spec at GET /api/openapi.json (public, no auth)
- Add justfile with common dev commands (build, test, lint, check, openapi, db)
- JWT secret auto-generates and persists to <STORAGE_PATH>/.jwt_secret
- Remove setup token: first admin setup is open until system initialized
- Fix schema.sql: move CREATE EXTENSION pg_trgm/ltree to top
- Update login UI and auth.js to remove setup token fields
Replace String with Arc<str> for fields that contain repeated static
values (mime_type, icon_class, icon_special_class, category) in
FileDto, FolderDto, and OptimizedFileContent.
These fields are computed from ~40 static lookup tables and cloned
on every request. With Arc<str>, clone becomes O(1) atomic increment
instead of O(n) heap allocation — saving thousands of allocations/s
under load.
Fields kept as String: id, name, path, folder_id, owner_id
(unique per item, rarely cloned).
Zero API impact — serde serializes Arc<str> identically to String.

Run `cargo fmt` across all Rust source files to enforce consistent
formatting (import ordering, line wrapping, match arm braces).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Standardize code formatting across all 173 Rust source files
using rustfmt. No functional changes - purely cosmetic.
This establishes a consistent code style baseline for the
project going forward.
