now Drive is purely a metadata
each drive has always a root folder
this model minimize Oxicloud changes, and simplify
the Drive name is simply the folder's root's name
note: owner of Drive has more permission that an owner of the root folder
First slice of Phase 2 (People / faces):
- migration: `faces` schema with `faces.persons` and `faces.faces`.
Embeddings are stored as BYTEA (512 x f32) — no pgvector extension
dependency; similarity is computed in-app (pgvector/VectorChord is the
documented scale-up). Cascade deletes (by user and by source file)
satisfy the right to erasure.
- OXICLOUD_ENABLE_FACES feature flag, OFF by default (biometric data,
opt-in per deployment).

Phase 1 server side, gated on OXICLOUD_ENABLE_PLACES (off by default):
- migration: partial index on storage.file_metadata(longitude, latitude).
- FileBlobReadRepository::list_geo_clusters — plain-SQL grid aggregation
(no PostGIS) scoped to the caller's own non-trashed photos, returning a
centroid, count and a representative file id per non-empty cell.
- PlacesService (caller_id-scoped; user-scoped data needs no authz check,
mirroring RecentService) with a zoom→cell-size mapping.
- GET /api/photos/geo?bbox=w,s,e,n&zoom=N returning GeoCluster[]. The route
is mounted only when the Places service is present, and is registered in
the OpenAPI path list.
The map frontend (PMTiles serving + MapLibre module) is deferred pending
the basemap-sourcing and vendoring decision.

Deduplication GC (garbage_collect, Phase 2):
- Add an orphan grace period before a ref_count=0 blob's backing file is
physically deleted, mirroring git's gc.pruneExpire. New
storage.blobs.orphaned_at records when a blob last reached ref_count 0;
the delete trigger and every decrement / 0-ref insert path stamp it,
every re-reference clears it.
- Cross-check that no manifest lists the chunk and no file points at the
blob before deleting it (mirrors Phase 1's file check), so a stale
ref_count can only delay collection, never delete live content.
- Unlink the backing files with bounded parallel fan-out.
Together these close a TOCTOU where a concurrent upload of identical
content could re-reference a chunk in the window between the GC row
delete committing and the backing file being unlinked. Individual file
deletes still reclaim eagerly; only bulk empty-trash and the periodic
sweep observe the grace window.
Trash: match ErrorKind::NotFound instead of substring-matching the error
message when treating an already-deleted item as success.
Content-index worker: supervise the drain loop and restart it with
backoff after a panic, instead of letting a panic silently freeze the
search index while the dirty queue grows unbounded.
Adds migration 20260802000000_blob_gc_grace.sql and an integration test
covering the grace window and reference cross-checks.

prepare migration of permission to roles
this simplify drastically database (permission are now simply defined in code)
and will permit reuse of the same ReBAC engine to define owners of drives
mapping:
```
Role::Viewer => &[Permission::Read],
Role::Commenter => &[Permission::Read, Permission::Comment],
Role::Contributor => &[Permission::Read, Permission::Create],
Role::Editor => &[
Permission::Read,
Permission::Comment,
Permission::Create,

],
Role::Owner => &[
Permission::Read,

Permission::Share,
Permission::Delete,
Permission::Manage,
],
```
storage.files carried 13 indexes; every INSERT/DELETE/rename maintains all of
them. Two are never chosen by the planner for any query the app issues —
verified statically (query text) AND empirically on a 50k-row table via
EXPLAIN + pg_stat_user_indexes over the real query shapes (idx_scan = 0):
- idx_files_name_search (user_id, name text_pattern_ops): file-name search is
`name ILIKE '%term%'` (served by the GIN trgm index); text_pattern_ops can
serve neither ILIKE, a leading-% substring, nor default-collation ORDER BY.
The one exact `name = $1` lookup is `WHERE folder_id=$1 AND name=$2`, served
by the UNIQUE (folder_id, name, user_id) index.
- idx_files_category_order (category_order): only emitted as a derived
type_order alias inside the folders⊎files UNION-ALL listing; the ORDER BY
runs post-UNION, so a single-column files index can't presort it. The real
listing uses idx_files_folder_id + a top-N sort.
Benchmark (50k single-row inserts, all triggers active): ~6% faster
(WITH: 10.46/10.71s; WITHOUT: 9.83/10.07s — every WITHOUT run beat every WITH
run) plus less disk and WAL on every file mutation. No query regression: the
planner never used these indexes. Reversible.
idx_folders_path (path text_pattern_ops) is intentionally KEPT — it serves
exact `WHERE path = $1` equality lookups.

Both sides added a parameter to create_application_services and a
setup step before it: this branch's storage-usage/quota service (for
the instant-upload path) and main's Tantivy content index (for
SearchService). The resolution keeps both — the signature takes both
arguments and the build runs storage usage as step 3c and the content
index as 3d.
https://claude.ai/code/session_01WdNenpnujNR2sc32XVvwfS
/api/search now finds files by CONTENT as well as by name: BM25-ranked
matches over extracted text (PDF, Office OOXML/ODF, plain text/code)
with typo-tolerant fuzzy terms and search-as-you-type prefix matching,
served from an embedded Tantivy index at {storage}/.search-index.
Pipeline (all off the request path, mirroring tree-etag + thumbnails):
- statement triggers on storage.files append to a durable dirty queue
(storage.search_index_dirty) - every write surface (REST, WebDAV,
NextCloud, WOPI, trash) is covered, crash-safe by construction
- ContentIndexWorker drains the queue on the maintenance pool, extracts
text once per unique BLAKE3 blob (storage.blob_extracted_text cache:
N copies = 1 extraction, renames/moves = 0 re-extraction) and applies
batched single-writer Tantivy commits; queue rows are deleted only
after the commit succeeds (at-least-once, idempotent upserts)
- the index is a derived artifact: a version-marker mismatch wipes and
reseeds it from Postgres, which remains the single source of truth
SearchService merges content hits into the existing name search: hits
are hydrated through ONE SQL round-trip that re-applies user scope,
trash state and every active filter (a stale index id can never leak),
scored below name matches, and returned with a plain-text snippet and
a match_source field. Index failure or
OXICLOUD_ENABLE_CONTENT_SEARCH=false degrades to name-only search; a
discard-only janitor keeps the trigger-fed queue bounded while disabled.
The frontend renders the snippet under the file name in list view.
New dependencies: tantivy 0.26, zip 8.6 (deflate only), pdf-extract 0.10.

Phase 1 of the delta-sync plan, server side. The CDC store already shares
unchanged chunks between file versions after the bytes arrive; these three
stateless endpoints move that detection to the client, so editing a few
bytes of a large file uploads ~1 MiB instead of the whole file:
- POST /api/files/delta/negotiate — given the file's chunk hashes, answer
which ones the caller must upload. User-scoped and purely advisory.
- PUT /api/files/delta/chunks — missing chunks as [u32 BE len][bytes]
frames (streaming parse, ≤1 MiB per frame, chunk_max_bytes per request).
Every hash is recomputed server-side; chunks land as ref_count=0 orphans
that a commit pins or the periodic GC sweeps — no session table.
- POST /api/files/delta/commit — pin one reference per distinct chunk with
a single UPDATE…RETURNING restricted to chunks the caller is entitled
to (reachable through their own non-trashed files, or unreferenced
orphans); anything else returns 409 {still_missing} for the client to
upload and retry. The pinned sequence is then RE-READ and the whole-file
BLAKE3 recomputed before any manifest exists — a declared file_hash is
never trusted, because a forged manifest would poison future whole-file
dedup hits for other users. The manifest accounting is shared with the
byte path (attach_manifest, extracted from store_from_stream); the file
row is created (201) or its content swapped by file_id (200). Owners of
the exact file_hash short-circuit to a pure reference bump.
Supporting pieces: GIN index on chunk_manifests.chunk_hashes (containment
probes were sequential scans), claimable/pin/release/store-loose/verify
primitives on DedupService, update-by-id with Update-permission AuthZ on
FileUploadService, per-caller rate limiter (240/min), audit events with
stable reasons (rate_limited, chunk_verification_failed,
file_hash_mismatch), OpenAPI + docs/delta-upload-protocol.md, framing
parser unit tests and a PG-gated integration suite covering the
entitlement matrix (owned/foreign/orphan/unknown), orphan registration
and the verification read.
Verified end-to-end against PostgreSQL 16 with a node client hashing via
the vendored WASM: a 24 MB file delta-committed in 96 fixed-size chunks;
a 3-byte edit then negotiated missing 1/96 and synced with 278 KB on the
wire vs 24 MB (98.9% saved), downloading byte-identical. A second user
probing the same chunks got nothing (negotiate: all missing; commit: 409
with all 96 still withheld); a forged file_hash returned 400 plus the
audit line; a commit referencing one never-uploaded chunk returned 409
naming exactly that hash; the GIN index serves containment probes
(Bitmap Index Scan) once the planner favors it.

Replace the per-row tree_modified_at bump triggers with AFTER ... FOR
EACH STATEMENT triggers using transition tables: each DML statement now
pays one bump covering the distinct ancestor chains of all affected
rows (locked in id order so concurrent bumps over overlapping chains
cannot deadlock), instead of one chain UPDATE per affected row.
Value-based change detection replaces UPDATE OF column lists (PG
forbids those with transition tables), so EXIF media_sort_date syncs
and no-op updates no longer bump at all, and file moves now invalidate
the source chain as well as the destination.
Also fix a latent bug surfaced while testing this: the descendant
path/lpath cascade (trg_folders_cascade_path) was declared AFTER
UPDATE OF path, lpath, but rename/move statements SET name/parent_id,
and BEFORE-trigger rewrites do not count for UPDATE OF — the cascade
never fired, leaving every descendant folder with a stale path/lpath
after any rename or move. The migration canonically repairs existing
trees and re-creates the cascade on the columns the app actually
writes.
delete_expired_bulk now deletes in LIMIT-ed batches (1000 files / 100
folders per round, each its own implicit transaction) ordered by
trashed_at and served by new partial indexes over trashed rows, so
retention purges no longer hold one unbounded transaction.
Verified against a local PG16 cluster: all migrations apply from
scratch, the new one re-runs idempotently, and a 16-case behavioral
battery passes (chain bumps for insert/update/delete/move/trash, EXIF
invisibility, no-op invisibility, cascade repair, FK-cascade depth
guards, batched purge shape and partial-index plan).

This solve issue with 2 migrations made the same day, due to merge on pull request, DB migration is blocking
the same version prefix:
- 20260625000000_files_user_size_index.sql (Dio)
- 20260625000000_folder_tree_modified_at.sql (Ed)
They were renamed to ...0001 and ...0002 (disjoint versions) + protection like "IF NOT EXISTS"
I have opt for an automated clean up of old entry:
`DELETE FROM _sqlx_migrations WHERE version = 20260625000000;`

GET /api/auth/me ran a synchronous O(N) SUM(size) over all the user's
files plus an unconditional UPDATE of auth.users on every call — one of
the most frequently hit endpoints — adding per-request latency, DB write
load, dead tuples and WAL even when nothing changed.
- /api/auth/me now serves the cached storage_used_bytes column instead of
recomputing it inline.
- New StorageUsageService::start_reconciliation_job runs a periodic sweep
on the maintenance pool that keeps the cached value current for every
mutation (uploads, deletes, trash), so freshness no longer depends on
hitting /me. Interval via OXICLOUD_STORAGE_USAGE_RECONCILE_SECS (default
600s, floored at 30s; first sweep deferred one interval to avoid boot load).
- update_storage_usage only writes when the value actually changes
(IS DISTINCT FROM), so the sweep produces no dead tuple / WAL on no-ops.
- New covering partial index idx_files_user_size_active makes the usage
SUM an index-only scan instead of a heap scan over all the user's files.
Also collapse the same pre-existing clippy collapsible_else_if in
carddav_handler that blocks the -D warnings gate on this base.

this is required to ensure NextCloud client will be aware of changes
In the future a Cursor will be better, this will be for OxiCloud-desktop
- add coalesced protection to avoid mail bombing if an invited goes many grant in a short period
- add resentd method in share menu item (work for both internal and external users)
- user can disable email notification via his properties
- add env variable from admin to disable notifications
- OIDC JIT define the locale only at user creation, user can so change his preference later
- invited users will inherit inviter's locale
- email will use prefered_locale
- login to a new browser will use prefered_locale
magic-link as now 2 modes:
- invitation: long TTL (24), no challenge
- passwordless login: short TTL (10min), cookie challenge to ensure that
user goes back to same browser (no man in the middle capturing email)
username: now optional, if defined 2..64 chars
password: now optional (no mode __NO_PASSWORD...__)
oidc: now optional
important: if need Nextcloud, username must be defined
- SMTP has a mock to enable end to end test and validate the whole path
(via OXICLOUD_SMTP_MOCK)

schema migration, User entity additions, and three defense-in-depth gaps closed, with all 280 unit tests and 13 Hurl files green
infrastructure (lettre + EmailSender port).
- Migration migrations/20260612000003_users_username_email_login.sql — adds nullable given_name/family_name columns to auth.users.
- User entity (src/domain/entities/user.rs) — has_login_credential() placeholder-check encapsulation, set_username revalidating setter, given/family-name fields + getters/setters, validate_username widened 32→254 and now accepts email shape.
from_data_full extended with two new params; all 7 callsites in user_pg_repository.rs updated.
- Schema-side legacy guards (src/application/services/auth_application_service.rs) — bumped the duplicated 32-char check in setup_create_admin and admin_create_user to 254 to match.
- Gap #1 (subject_group_service.rs) — add_member now rejects external candidates with an audit-logged AccessDenied. Service gained an Arc<UserPgRepository> field, wired through DI. New integration test test_external_user_cannot_be_added_as_member.
- Gap #2 (user_repository.rs + auth_ports.rs + user_pg_repository.rs) — list_users/search_users gained an include_external: bool param defaulting effectively to false everywhere internal-user-facing. auth_application_service exposes a new
list_users_including_external for the admin surface.
- Gap #3 (pg_acl_engine.rs) — expand_user now SELECTs is_external and skips INTERNAL_GROUP_ID for externals; defaults to is_external=true on missing user to fail closed.

Security: session hardening
Refresh token rotation with theft detection (family_id)
- Added family_id column to auth.sessions (migration 20260507000000_session_family.sql) grouping all tokens issued from the same login into a family
- On refresh, the new session inherits the parent's family_id
- If a revoked token is replayed (indicates the token was stolen after rotation), the entire family is immediately invalidated and a warning is logged — forcing re-authentication on all devices
SameSite=Strict on refresh cookie
- Access cookie stays SameSite=Lax (needed for top-level navigation)
- Refresh cookie upgraded to SameSite=Strict — it is only ever used for explicit POST to /api/auth/refresh, never via cross-site navigation
Refresh token TTL: 30 days → 7 days
- With rotation, active sessions auto-renew and effectively never expire
- Inactive sessions expire after 7 days instead of 30, reducing the theft window
When the storage.files table already exists from a manual migration,
CREATE TABLE IF NOT EXISTS is skipped entirely, so the new
media_sort_date column is never added. Add an ALTER TABLE ADD COLUMN
IF NOT EXISTS immediately after the CREATE TABLE to handle both fresh
and pre-existing databases.

Replace manual schema.sql application with sqlx's built-in migration
system. Migrations are embedded at compile time and tracked in the
_sqlx_migrations table. Pending migrations run automatically on startup.
- Move db/schema.sql → migrations/20260307000000_initial_schema.sql
- Remove apply_schema() and split_sql_statements() from db.rs
- Add run_migrations() using sqlx::migrate!() macro
- Remove docker-compose schema.sql mount (app handles it now)
- Enable sqlx "migrate" feature in Cargo.toml
Future schema changes: add a new timestamped .sql in migrations/.
