Summary

RFC-021 and its whole implementation, in one PR: what a scan leaves out, symbolic links, missing tracks, the library lifecycle, and a filesystem watcher. It answers the five gaps of the 2026-10-24 comparative audit. RFC-018's guarantees hold throughout: the skip pre-check, the Walked/unclaimed relocation safety, and nothing marked missing when the walk was incomplete.

Scope	What lands
Exclusions	Built-in exclusions: dot names except .waveflow-managed at the root, @eaDir, #recycle, #snapshot, $RECYCLE.BIN, System Volume Information, lost+found. A per-folder .waveflowignore with gitignore syntax, read through the ignore crate's matcher beside the existing walkdir walk. An empty file excludes its folder, except at the root. An unusable file makes its folder unreadable in RFC-018's sense; at the root it fails the scan.
Excluded = not discovered	An excluded track becomes unavailable like a deleted one and can be a relocation source. It comes back under the same id when the rule goes. New scan_job.excluded counter.
Symbolic links	Per-library follow_links, off by default, set by an administrator. Off: every link is counted in scan_job.skipped_links and logged (first 20 one by one, then a count). On: a link is followed only when its canonical target stays inside the root. Outside, broken and looping links are skipped and counted. A followed file is indexed under its canonical path, so one file is one track and the stored path never holds a link (secure_track_path is unchanged).
Missing tracks	track.unavailable_since. GET /api/v2/libraries/{id}/unavailable-tracks lists each track with what a purge costs (playlist entries, favourites, plays). POST …/unavailable-tracks/purge takes {"track_ids": […]} or {"all": true}, never neither. It runs under the writer gate in one transaction, removes only what is still unavailable, runs the scan's consolidation (no empty album or artist left), removes orphaned favourites, ratings, search rows and genres, and releases canvases left with no link. It answers 409 while the library scans. Optional retention, WAVEFLOW_UNAVAILABLE_RETENTION_DAYS, off by default, runs hourly. Web page "Missing files" and CLI library unavailable / library purge.
Lifecycle	PATCH /api/v2/libraries/{id} (name: owner or admin; path / follow_links: admin on an admin credential, queues a scan with the new trigger library_moved). DELETE /api/v2/libraries/{id} (admin, body {"confirm": "<current name>"}). GET …/settings (admin). All refuse with 409 during a scan. CLI `library rename
Watcher	notify 8 (default features only), with the server's own per-library debounce: quiet for WAVEFLOW_WATCH_DELAY_SECS (10 s), or 30 delays at most. WAVEFLOW_WATCH (default on). No scan starts while one runs for that library; the library stays pending instead. Reads, atime changes and .waveflow-managed are ignored. An overflow marks everything pending. The watched set follows the libraries. A watch that cannot be established is logged once and the library falls back to the periodic scan. The network-mount caveat is in docs/operations.md.

Decisions worth a reviewer's look

• Links are confined to the root, and indexed canonically. That is the brief's rule. A beets link: yes farm whose files live outside the root is therefore not followed. The RFC and docs/operations.md give the in-tree recipe (store folder excluded by .waveflowignore, links into it) and list an allowlist of extra roots as still open.
• Built-in exclusions cannot be overridden by ! in an ignore file.
• The scan_job table is rebuilt to admit the triggers watch and library_moved, since SQLite cannot alter a CHECK. The rebuild follows the participants precedent (migrations run with foreign keys off, then foreign_key_check). tests/migrations.rs now seeds a scan job, its error and a track's last_seen_scan_id at every released schema and reads them back.
• Deletion order is explicit: tracks, album participants, albums, artists, genres, then the library. A track restricts its album, and an album its album artist.
• Administrative standing comes from the credential, not the account. This was raised in review before the PR opened. standing_on first took "admin" from the account row alone, so an admin-owned token whose scopes stop short of admin (for example write) could rename or purge any library. Services now take a LibraryActor { id, admin_credential }, which the handlers build with the same two checks authenticated(…, Access::Admin) makes. The CLI acts as the operator. Test: a_narrowed_admin_token_has_no_say_over_a_foreign_library.

Test plan

Run locally, in a private CARGO_TARGET_DIR:

• cargo fmt --all --check
• cargo clippy --all-targets --all-features -- -D warnings
• cargo test --all-features (full suite)
• bun --cwd=webapp install, bun --cwd=webapp run build, biome check . (no new diagnostics), vitest run

New tests:

• unit (src/scanner.rs, src/watcher.rs): built-in exclusions, ignore-file rules, debounce, never a scan during a scan, event filtering;
• tests/scanner.rs: exclusions and ignore files, excluded → unavailable → back, unusable ignore file, links, purge, purge rules and retention, moved root keeps identities, role model, deletion leaves no row, watcher end to end;
• tests/native_api.rs: the HTTP routes by standing, and the narrowed admin token;
• tests/cli.rs: rename, set-path, purge and delete from the CLI;
• tests/migrations.rs: scan history survives the scan_job rebuild.

Verified by inversion

Each fix was reverted, the test was seen failing for its own reason, and the fix was restored with git diff clean. Every inversion was re-run in a private CARGO_TARGET_DIR, after a shared one turned out to let cargo reuse another worktree's artifacts.

Fix reverted	Test that failed, and why
Built-in exclusions off	built_in_exclusions_and_ignore_files_leave_files_out: @eaDir, .hidden and ._ files indexed
.waveflow-managed exemption dropped	the same test: the received file disappears
Excluded treated as unreadable	an_excluded_track_becomes_unavailable_like_a_deleted_one: unavailable 0 instead of 1
unavailable_since not written	the same test: "the time it went missing is recorded"
Unusable ignore file read as no rules	an_ignore_file_that_cannot_be_used_keeps_its_tracks: errors 0 instead of 1
Outside links accepted	links_are_followed_only_inside_the_library: skipped_links 2 instead of 3
Unfollowed links not counted	the same test: "every link must be counted" (0 instead of 5)
Purge ignores availability	a_purge_removes_only_what_is_still_missing: 2 purged, "a track that came back must be kept"
Purge consolidation removed	the same test: the empty album, and its favourite, outlive the purge
Canvas release removed	the same test: the canvas row stays
Purge scan lock removed	a_purge_is_explicit_and_waits_for_no_scan: no Conflict
Path change allowed to the owner	the_lifecycle_follows_the_role_model: no Forbidden
Delete keeps favourites	a_deleted_library_leaves_no_row_behind: "a favourite of a deleted track outlived it"
Explicit deletion order replaced by the library cascade	the same test: FOREIGN KEY constraint failed, which confirms the order is needed
Scan uses the queued record instead of re-reading the library	a_queued_scan_reads_the_library_as_it_is_when_it_runs: the job fails on the old root
Watcher answers no event	a_watched_change_is_scanned_once_it_settles: no scan followed the change
Watcher ignores running scans	unit test no_scan_starts_while_one_runs_for_the_library (and the event-filter test)
Migration copies no scan_job rows	every_released_schema_upgrades_with_the_rows_it_was_holding: boot refuses, 2 broken foreign keys
Credential admin flag forced true	a_narrowed_admin_token_has_no_say_over_a_foreign_library: 200 instead of 404

The web client was also checked by hand against a throwaway server on port 4599. A file deleted on disk was picked up by the watcher with no manual scan and listed on "Missing files", then purged with two clicks. The library was renamed, then deleted with its typed name, from the admin panel.

Deferred (RFC "What is still open")

• The user sync journal is not written on a purge or a deletion. Devices learn that a track is gone from the library feed's delete.
• Following links outside the root, to an allowlist of further roots.
• Undoing a purge.
• A per-library watcher switch.
• Combining watching with folder-level scans.

Suggested labels: scope: tooling

Merge Risk: Minimal · up to e6adc

No actionable merge-blocking issue is established by the supplied evidence; the change is ready for normal validation.

Security architecture risk: Moderate · up to e6adc

Filesystem settings and destructive operations have explicit permission checks. However, command-line lifecycle actions use process-local scan coordination. Concurrent use with a running server could undermine the scan-versus-purge safeguard and irreversibly remove saved state belonging to every member of the affected library.

Retained concerns

• Medium · reliability · inferred: The new CLI lifecycle commands initialize their own ScanManager, whose library mutex is not shared with the running server. In documented CLI/server coexistence, the CLI purge guard therefore does not exclude a server scan that may be about to restore or relocate an unavailable track. Purging at that point can irreversibly remove the track's dependent user state; changing the root can likewise invalidate an active scan's filesystem snapshot. Administrator-only CLI access and transactional deletion limit authority and partial database writes, but do not establish exclusion across the full cross-process transition.

Security review details

Security Blast Radius

• observed — An administrator can select an existing server-readable directory as a library root. Purge authority reaches unavailable tracks and their dependent state for every member of the selected library, but target selection and deletion retain library_id constraints.

Security Findings and Attack Paths

• inferred — The retained concern is an integrity and failure-containment path requiring an authorized local operator: CLI purge can overlap a server scan because their library locks belong to different managers. This can defeat the intended protection for tracks about to return through relocation. It is not evidence of a remotely reachable authorization bypass.

Trust Boundaries and Controls

• observed — Administrative standing requires both an active administrator account and an administrative credential. Owners may rename libraries but cannot change roots or link policy; administrators, owners and managers may curate unavailable tracks. Purge rechecks standing inside its transaction and filters named track IDs by the requested library.

Resilience and Maintainability Implications

• observed — Purge commits catalog cleanup and audit state before releasing canvas blobs. Blob release checks whether references remain under a blob lock, and unsuccessful cleanup leaves unreferenced bytes for the existing sweep rather than undoing the committed catalog operation.

Hardening Proposals

• proposed — Make lifecycle exclusion authoritative across processes: route online CLI mutations through the running server, or use a database-backed scan lease and fencing generation shared by scanners and destructive operations. Root changes and purges should reject or fence scans holding an earlier generation.

Re the outside-diff comment in review 5640993965 (src/services/library_lifecycle.rs:548-580, "make the update and the enqueue atomic"): confirmed against the code, and fixed in 79bd494.

The scan that a new root or follow_links value owes is now inserted by Database::insert_scan_job_in, inside the same transaction and under the same writer gate as the UPDATE library. If the job cannot be queued, the change rolls back with it. The job is only spawned after the commit, so a committed move always has its scan.

Test: a_move_whose_scan_cannot_be_queued_is_not_stored (tests/scanner.rs). An SQLite trigger refuses scan_job inserts with the trigger library_moved. The move must then fail and leave root_path unchanged. Inversion: committing the update before queuing the job (the previous shape) stores the new root, and the test fails with "the new root was stored without the scan it owes".

scan périodique sert de recours uniquement lorsque son intervalle est non nul ;
avec `WAVEFLOW_SCAN_INTERVAL_SECS=0`, `Config::from_env` le désactive et le
catalogue peut rester obsolète sur les montages réseau qui ne signalent pas les
changements distants.

- Around line 5979-5991: Dans la boucle de suivi du scan, vérifiez le statut
renvoyé à chaque tentative et faites échouer le test dès qu’il vaut « failed ».
Suivez l’achèvement avec un indicateur et, après les 200 tentatives, faites
échouer le test si le statut « completed » n’a pas été atteint.

- Line 7030: Modifiez le prédicat client mayCorrectTracks pour autoriser aussi
user.role « admin », indépendamment du rôle de la bibliothèque. Séparez les
scénarios de test : conservez le refus avec une session non administratrice et
ajoutez un cas positif où l’administrateur a le rôle de bibliothèque « listener
» et peut consulter les pistes indisponibles.
