bvandeusenandClaude Opus 5	abe449b4f2	feat: placement reconciler tasks + API (4246, slice 3b) ... Three Celery tasks wrapping the 3a service, and the endpoints that drive them. Routed to `maintenance_long` alongside backups: 33k renames on NFS have no business in the quick lane where the self-healing sweeps live (the 2026-06-07 starvation). A durability bug in 3a, found by thinking about what a crash costs rather than by a failing test: `apply_run` wrote its ledger only at the end, so a worker dying at row 30,000 of 33,789 would have taken the undo information for the first 29,999 with it — and that ledger is the ONLY record of where those files came from. It now persists every 200 moves. Two things fell out of writing that: - `_persist` reassigns `run.moves`, so the loop had to snapshot the plan first rather than iterate the attribute it rewrites. - the reassignment is itself load-bearing: SQLAlchemy does not track in-place mutation of a JSONB list, so an `.append()` alone would never reach the database and the ledger would have stayed silently empty. Re-running a partially-applied plan is safe — the moved rows no longer match their `from` and refuse as "row moved since planning" — but `apply_placement` deliberately has NO autoretry: re-entering a half-applied plan should be the operator's call after reading what happened, not the queue's. Endpoints gate on run state as well as the service does, so a stray POST cannot re-apply an applied run. The list response omits `moves` (an applied whole-library run carries tens of thousands of entries); the detail endpoint includes them, because that detail IS the preview read before agreeing.

bvandeusenandClaude Opus 5	9ccc460c69	feat: placement reconciler — plan, apply, revert (4246, slice 3a) ... Milestone #421 step 3, reframed on the operator's steer: not a one-off migration but the system that keeps the tree true. The 33,789 misplaced rows the survey found are just its first run. The placement half was already done, verified by reading each writer rather than assuming: downloads have always written `<root>/<slug>/<platform>/` (gallery_dl.py:523), attach_in_place leaves files where the downloader put them, and `_copy_to_library` / `_supersede` became canonical in #4244. So nothing is written off-canon today; what remains is the backlog and a standing check for future drift. `LibraryPlacementRun` (migration 0099) holds the plan as JSONB, and that one structure does three jobs: it is the PREVIEW the operator reads, the list the APPLY executes (rather than re-deriving the set, so the two cannot disagree), and — because `from` is retained — the UNDO. The undo is the point. It makes a 33,789-file operation something to do one artist at a time, look at in the gallery, and reverse if it reads wrong. That settles whether artist_id or the folder held the truth (spike #4257) by doing rather than by arguing it from a 50-row sample. An applied run is therefore HISTORY, not state — lesson #4226's trap, since it is the only record of where those files used to be. The model and the migration both say so: any future retention here may prune ready/cancelled/ error runs, never an applied one. Everything fails closed. The apply re-checks each row against what the plan recorded — source still there, destination still free, row still pointing where the plan said — because a download or a supersede can land in between. A refusal is recorded with its reason and the run continues; one stale row is not a reason to abandon the other 33,788. The row is updated only after its rename lands, so a failed move can never leave `path` naming a file that is not there. Writing the collision test caught the code disagreeing with its own comment: it claimed the first of two rows wanting one destination and skipped the second, silently picking a winner by iteration order. Now it counts first and filters after, so genuinely neither is planned. Thumbnails are sha-addressed, not path-keyed, so they do not move — pinned by a test.

bvandeusenandClaude Opus 5	9728407539	docs: record why the misplaced-rows LIKE needs no escaping (4245) ... `startswith` compiles to LIKE, where `_` and `%` are wildcards, and the call does not escape them. That is safe only because `slugify` reduces a slug to [a-z0-9-] — an invariant living in a different module, which is exactly the kind of thing that gets widened later without anyone connecting the two. Worth naming because `poch4n_art` is a real directory here: if slugs ever carried underscores, that prefix would start matching `poch4nXart` and the sweep would quietly mis-file one artist's rows.

bvandeusenandClaude Opus 5	fc982f74b9	feat: survey which image rows sit outside their artist's canonical directory (4245) ... Step 2 of milestone #421. The disk survey counted FOLDERS; this counts ROWS, which is the number that matters — every move in step 3 is a row update, and `ImageRecord.path` is the only pointer at the bytes. `library_layout.py` holds the decision in two shared pieces, and both halves of the consolidation spread them rather than restating them (rule 93, the _x_conditions shape from snippet #3087): - `_misplaced_conditions(root, artist_id, slug)` — rows of one artist whose file is not under that artist's directory. The prefix carries a trailing separator deliberately: without it `ara` matches everything under `arbuzbudesh/`, and one artist reads as fully placed while another's rows are silently skipped. Both are real artists here, hence the test. - `destination_for(path, root, slug)` — where a row's file belongs, or None when it must not be moved: outside the images root, or under one of the reserved stores (`thumbs`, `attachments`, `cookies`, `secrets`, `_backups`, `_quarantine`). Relocating those would move the thumbnail cache or the credential key into an artist folder. `destination_for` diverges from `canonical_subdir` in exactly one case, and the docstring says why: a file at the images ROOT with a known artist moves under that artist here, where the import-time helper leaves it alone. The two answer different questions — an empty subdir at import means no artist was resolved, while a row that already carries an artist_id is an anomaly with a known correct home. The 660 unattributed files have no artist_id at all, so no predicate reaches them; they are counted and left for task #4247. `GET /api/cleanup/layout` exposes it. `?check_disk=1` additionally stats every destination for collisions and missing sources — the conditions the apply refuses on — but it is off by default so the count-only pass answers "how big is this" in seconds instead of timing the request out on NFS. Nothing here writes; a test asserts that against both the row and the file.
