Implements #49: fetch, decrypt, store, and index Ente's per-file ML data (face detections + CLIP embeddings), the store+fetch+index unit. The search surface (similar/searchByEmbedding) stays for #50.
What changed
New src/mldata-fetch.ts holds the /files/data/fetch (type mldata) decrypt+gunzip, now shared by metadata-backup.ts (whole-account loop) and the library (single-batch unit through the pool). Behaviour of the backup path is unchanged.
New src/library/mldata.ts (MLDataStore): one payload file per fileID written by rename under cacheDirectory/mldata/ (present means complete), plus a derived index clip.json (fileIDs in order + embedding length) and clip.f32 (embeddings packed as one Float32Array, loaded in one read, no parse). The index is rebuilt from the payloads when missing or structurally inconsistent with the files present, and appended to (or overwritten in place on refetch) as payloads arrive.
Library fetches ML data after each refresh through the #45 metadata pool, for every known file absent from mldata/ or whose updationTime advanced, reporting via onProgress (operation: "fetchMLData") and status(). RAM holds only the id list and Float32Array; payloads are read from disk on demand.
Worth knowing
updationTime refetch bookkeeping lives in mldata/fetched.json, separate from the index because the payload files (the source of truth) carry no updationTime and the index is defined as rebuildable purely from them. Losing it only forgoes update-driven refetch until the next fetch.
The ML pass is fire-and-forget off the refresh success and self-guarded, so a slow first-run backfill never stalls the metadata refresh interval and never marks a refresh failed.
LibraryClient.fetchMLData is optional: a client without it disables ML fetching, so the existing metadata-only refresh tests are untouched.
make check green (lint via Dockerfile.lint; the dangling lint image was removed).

**What changed**
- New `src/mldata-fetch.ts` holds the `/files/data/fetch` (type `mldata`) decrypt+gunzip, now shared by `metadata-backup.ts` (whole-account loop) and the library (single-batch unit through the pool). Behaviour of the backup path is unchanged.
- New `src/library/mldata.ts` (`MLDataStore`): one payload file per fileID written by rename under `cacheDirectory/mldata/` (present means complete), plus a derived index `clip.json` (fileIDs in order + embedding length) and `clip.f32` (embeddings packed as one `Float32Array`, loaded in one read, no parse). The index is rebuilt from the payloads when missing or structurally inconsistent with the files present, and appended to (or overwritten in place on refetch) as payloads arrive.
- `Library` fetches ML data after each refresh through the `#45` metadata pool, for every known file absent from `mldata/` or whose `updationTime` advanced, reporting via `onProgress` (`operation: "fetchMLData"`) and `status()`. RAM holds only the id list and `Float32Array`; payloads are read from disk on demand.
**Worth knowing**
- `updationTime` refetch bookkeeping lives in `mldata/fetched.json`, separate from the index because the payload files (the source of truth) carry no `updationTime` and the index is defined as rebuildable purely from them. Losing it only forgoes update-driven refetch until the next fetch.

1. Flaky test; make check is not reliably green (blocks the definition of done).test/library/mldata.test.ts › "refetches a file whose updationTime advanced" fails intermittently: it went red on 2 of 5 reruns here and failed the make check gate on the rebased head. The test waits only for the ML fetch to be invoked — client.mlFetchCalls.length grows the instant the mock is entered — then immediately reopens the store from disk and asserts clip.f32 holds the refetched embedding [9,9,9]. But storeFetched (which writes the payload and rewrites clip.f32/clip.json) runs and is awaited after the fetch call is recorded, so the reopen often reads the pre-refetch vector and the assertion sees [0.5,0.25,0.75]. The product code is correct; the defect is test synchronization, but it leaves a next/main-bound branch with a red make check. Acceptable: gate the reopen on a signal emitted only after the store has persisted — e.g. wait for status().lastMLFetchAt to advance past its first-pass value, or for the reopened index to actually reflect the new embedding — rather than on the fetch merely being called. (The first Library test has a narrower version of the same window, waiting on mlIndexed which is set in memory before persistIndex resolves; worth hardening the same way.)

The flaky test from the prior review is fixed: the refetch test in test/library/mldata.test.ts now polls the persisted, atomically-renamed index for the new embedding instead of the fetch-call count, and the first Library test waits on lastMLFetchAt (set only after storeFetched resolves and the index is on disk). Deterministic across repeated runs here. One correctness gap and the two length overruns from the prior review remain.
1. The index is not rebuilt when a payload is present on disk but missing from the index; CLIP embeddings are silently and permanently dropped after an interrupted fetch (src/library/mldata.ts: tryLoadIndex around line 282; storeFetched around lines 137-178). storeFetched writes every payload file in a batch (by rename) and only afterward rewrites clip.json/clip.f32 once. If the process dies between those two steps — realistic during a first-run whole-account backfill in batches of 200 — the payloads are complete on disk but absent from the index. On the next open, tryLoadIndex checks only that every id the index names is still present and that clip.f32 is the size the index implies; it does not check the reverse, so it loads the stale index as consistent and never rebuilds. neededFor then treats those files as present and never refetches them, so their embeddings stay out of the index permanently (recoverable only by manually deleting the index files). The definition of done requires the index be "rebuilt ... when it disagrees with the files present"; this satisfies only one direction of disagreement. Confirmed by probe: a payload written to disk without an index update is not indexed on reopen and does not self-heal. Acceptable: on open, treat the index as disagreeing (and rebuild) when an embedding-bearing payload present on disk is absent from the index, not only when the index references a payload that is gone.

Ente's per-file ML data (face detections + CLIP embeddings) is fetched,
decrypted, and cached under cacheDirectory/mldata/, never in
metadata.json. A new mldata-fetch module holds the decrypt+gunzip, reused
by the metadata backup and the library. MLDataStore writes one payload
file per fileID by rename (present means complete) and derives clip.json
+ clip.f32 (embeddings packed as one Float32Array, one-read load). On open
the index is rebuilt whenever it disagrees with the payloads in either
direction — an id it names is gone, or an embedding-bearing payload on
disk is absent from it — so a crash between writing payloads and rewriting
the index self-heals instead of dropping those embeddings. Appended to as
payloads arrive; fetched.json records each file's fetch-time updationTime.
Model: opus-4-8
Both blockers from the prior reviews are fixed and verified. The refetch test is now deterministic — it polls the atomically-renamed index for the new embedding and waits on lastMLFetchAt, set only after storeFetched persists — and is green across repeated runs. The crash-consistency gap is closed: tryLoadIndex now treats an embedding-bearing payload that is present on disk but absent from the index as a disagreement and rebuilds, so a payload written without an index update self-heals on reopen with no manual delete (confirmed by probe, and by a test that fails when that reverse check is removed). The commit body is now within the guideline.
One finding remains.
