Implements #46 — the on-disk content and thumbnail cache.
What changed
src/library/content.ts (new): ContentCache keyed by fileID under cacheDirectory — flat originals/ and thumbnails/, dirs 0700, files 0600. Fetches through the request pools (#45) and the streaming decrypt / atomic writer (#40). Content appears only by the writer's rename (present-means-complete); the listing at open() is the record of what is cached, and orphan .quak-*.tmp files are reaped there.
Photo.original / Photo.thumbnail → {path, bytes}: one skipped event when present (cache or downloadDirectory), else fetch through the content/thumbnail pool and store. Cached paths land on PhotoRecord.thumbnailPath/originalPath.
lib.thumbnails.ensure(...) → per-file {fileID, path?, error?}: priority, dedup (a fileID downloads once), and abort (queued work dropped, an in-flight fetch kept).
Wiring: Library.open builds the cache from client.contentSource() or an injected source.
Traps the diff doesn't show
Two ensure calls with different signals for the same in-flight fileID share one pooled task, so the abort check follows the first submitter's signal.
getFileByID is a linear scan, matching the store's existing listFiles; no fileID index yet (eviction/precache are the later units).
Disclosures
Integrity is enforced by the reused streaming decrypt (every chunk authenticated, rename only on TAG_FINAL) plus a stored-file non-empty check.
Deferred, and a question for you: the metadata.hash comparison and fileSize fallback. The only in-repo hash fixture (test/model/decrypt.test.ts) is a placeholder, so the hash construction cannot be confirmed against fixtures — the issue's own precondition — and FileBlob.size is the encrypted object size, not the decrypted length this layer holds. Add a real (content, hash) fixture in a follow-up so the content-hash gate can be turned on?
Judgement call: the three thumbnail priorities map onto the pool's two tiers (visible → on-demand; ahead/background → background), so only currently visible thumbnails preempt.
make check is green (lint runs in Docker via Dockerfile.lint).

Implements https://git.eeqj.de/sneak/quak/issues/46 — the on-disk content and thumbnail cache.
**What changed**
- `src/library/content.ts` (new): `ContentCache` keyed by fileID under `cacheDirectory` — flat `originals/` and `thumbnails/`, dirs `0700`, files `0600`. Fetches through the request pools (#45) and the streaming decrypt / atomic writer (#40). Content appears only by the writer's rename (present-means-complete); the listing at `open()` is the record of what is cached, and orphan `.quak-*.tmp` files are reaped there.
- `Photo.original` / `Photo.thumbnail` → `{path, bytes}`: one `skipped` event when present (cache or `downloadDirectory`), else fetch through the content/thumbnail pool and store. Cached paths land on `PhotoRecord.thumbnailPath`/`originalPath`.
- `lib.thumbnails.ensure(...)` → per-file `{fileID, path?, error?}`: priority, dedup (a fileID downloads once), and abort (queued work dropped, an in-flight fetch kept).
- Wiring: `Library.open` builds the cache from `client.contentSource()` or an injected source.
**Traps the diff doesn't show**
- Two `ensure` calls with different signals for the same in-flight fileID share one pooled task, so the abort check follows the first submitter's signal.
- `getFileByID` is a linear scan, matching the store's existing `listFiles`; no fileID index yet (eviction/precache are the later units).
**Disclosures**
- Integrity is enforced by the reused streaming decrypt (every chunk authenticated, rename only on `TAG_FINAL`) plus a stored-file non-empty check.
- Deferred, and a question for you: the `metadata.hash` comparison and `fileSize` fallback. The only in-repo hash fixture (`test/model/decrypt.test.ts`) is a placeholder, so the hash construction cannot be confirmed against fixtures — the issue's own precondition — and `FileBlob.size` is the encrypted object size, not the decrypted length this layer holds.

FAIL — needs-rebase. The branch does not merge into the current next, and one definition-of-done item needs an owner ruling before merge.
Does not rebase onto current next. The branch was cut before the ML-data change (d7f415f) landed on next, and rebasing onto origin/next conflicts in src/library/index.ts. It is not cosmetic: next and this PR both add a pools?: RequestPools field to LibraryOptions, and both extend the Library constructor arguments and deriveNow. A correct resolution has to fold the two pools? declarations into one (keeping both is a duplicate-identifier compile error) and make Library.open build a single request-pool set shared by both the ML-data fetch and the content cache — two separate sets would defeat the shared concurrency caps. Acceptable: the rebased head compiles, make check is green, and one pool set serves both.
Integrity comparison is not wired, which the definition of done names. Issue #46 lists "integrity check wired" and asks that the content hash be compared to the file's stored hash (and stored), with a file-size fallback. This PR implements neither comparison; it relies on the streaming decrypt (each chunk authenticated, the file renamed into place only when the stream ends cleanly) plus a stored-non-empty check. The deferral is reasoned, and both reasons check out: the issue itself preconditions the hash on confirming its construction against a fixture, and the only hash fixture in the repo is a placeholder; and the file's size field is the server's encrypted object size, not the decrypted length this layer produces, so a size comparison as written would always mismatch. The authenticated decrypt already gives stronger integrity here than a hash compare would, so the practical gap is small — but because the definition of done names this item, it needs an explicit decision: accept the deferral (and track the follow-up fixture) or require the gate now. Acceptable: an owner decision recorded, and either the gate added or the deferral signed off.
The commit-message body runs about 160 words, past the ~120-word guideline. Much of it is legitimate disclosure and can simply be tightened. Acceptable: about 120 words or fewer.
The PR description runs about 308 words, past the ~250-word guideline. Acceptable: about 250 words or fewer.

Rework decision. Finding 1 (rebase) must be fixed: rebase onto current next and fold the two pools? declarations into ONE shared RequestPools set that serves both the ML-data fetch and the content cache; make check green. Finding 2 (integrity hash compare): manager ruling — accept the deferral, no owner ruling needed. The owner-approved design itself preconditions relying on the hash on confirming its construction, the only hash fixture is a placeholder, and FileMetadata.size is the encrypted object size (so the design's size fallback is wrong as written); authenticated streaming decrypt (per-chunk poly1305 + TAG_FINAL) already gives stronger integrity here. Tracked as #68. Findings 3-4 (commit/PR body length): the manager writes a concise squash message at merge; no action needed on the branch. A fresh reviewer re-gates after the rebase.

Add src/library/content.ts: a ContentCache keyed by fileID under
cacheDirectory (flat originals/ and thumbnails/, 0700/0600), fetching through
the request pools (#45) and the streaming decrypt / atomic writer (#40) so
present-means-complete. One shared pool set serves both this cache and the
ML-data fetch. Photo.original and thumbnail return {path,bytes}, skipped when
present; lib.thumbnails.ensure drives the thumbnail pool with priority, dedup,
and abort.
Integrity rests on the streaming decrypt (every chunk authenticated, renamed
in only on TAG_FINAL) plus a non-empty check. The stored-hash / size compare
is deferred (tracked in #68): the only in-repo hash fixture is a placeholder,
and the stored size is the encrypted object size, not the decrypted length.
Judgement call: three thumbnail priorities map onto two tiers.

PASS. Rebased cleanly onto current next (61dfec8), and both make check and make build are green in a fresh clone: the two pools? declarations are folded into one shared RequestPools that serves both the ML-data fetch and the content cache, the content/thumbnail cache meets #46 (fileID-keyed originals//thumbnails/, present-means-complete with orphan-temp reaping on open(), Photo.original/thumbnail, and thumbnails.ensure with priority, dedup, and abort), it reuses the pools, streaming decrypt/atomic writer, and read surface as intended, and the ordering and abort tests gate on observed persisted results rather than timers.
Disclosures:
The content-integrity hash/size comparison is absent by design; the deferral is accepted and tracked in #68, so it is not gated here.
