Closes#79.
Emit is latency-bound, not CPU-bound. Every blob costs two serial round-trips to the zone — a `ProbeKey` HEAD, then a `PutReader` PUT — so a hak with a few thousand resources pays a few thousand serialised latencies. Measured on the live sow-assets-manifest backfill: 26 s of CPU across 9.5 minutes of wall clock, on a 4-core host with 5 GB free and peak RSS of 51 MB.
`emit` now hashes, compresses and stores `--jobs N` resources at once, default 16 — matching `DEPOT_JOBS` and the transport's `MaxIdleConnsPerHost`, so a worker per connection needs no fresh TLS handshake. `--jobs 1` is exactly the old behaviour.
### Three properties had to survive
Each has a test in `internal/nwsync/jobs_test.go`:
- **Deterministic manifest bytes.** `emitterVersion` promises a manifest is a function of its artifact, so `entries` is index-addressed rather than appended to — a worker owns `entries[i]` alone and the slice comes back in artifact order whatever order uploads finish in. `TestEmitProducesTheSameIndexAtEveryJobCount` diffs the `.nsym` and its sidecar between `-jobs 1` and `-jobs 16`.
- **Index still lands last.** Any worker's failure aborts before a manifest is written. `TestEmitLeavesNoIndexWhenAParallelUploadFails` fails every blob PUT with 16 workers in flight and asserts no `.nsym` appears. Under `-race` it also covers the shared counters.
- **Identical content still shares one blob.** This one bit during development and is the reason to read the diff carefully: serially, the sink's existence check absorbed two resrefs with identical bytes. In parallel both workers probe, both miss, and both upload — `TestEmitWritesBlobsAndManifest` caught it as "wrote 2 blobs, want 1". Claiming the sha1 in-process restores the dedupe and skips a probe round-trip as well.
### Memory
Peak now tracks the resources in flight rather than one resource. The ceiling is `N` × the 15 MB `fileSizeLimit` plus its compressed copy — bounded by a constant this package enforces itself, and still not tracking the archive. `TestEmitPeakMemoryIsBoundedByJobCount` re-runs the #76 regression check at `-jobs 8`: a hak 8× bigger still costs the same.
This is only cheap because of #78. Before streaming emit, N workers would have meant N whole archives resident.
### Not done
Skipping the `ProbeKey` HEAD on a first-time emit would halve round-trips, but doubles uploaded bytes on a re-run — which is exactly what a backfill is. Noted in #79 so it is not rediscovered; parallelism is the better lever and this PR takes it.
Worker compression still serialises on `blobEncoder`, which is `WithEncoderConcurrency(1)` for the memory reason in `compressedbuf.go`. At 26 s of CPU per hak that is not worth trading memory for, but it is where to look if the numbers ever say otherwise.

Documents what `nwsync emit --out DIR` actually produces, so a zone can be checked by hand.
The trap this removes: a blob's filename is the SHA-1 of the resource's *original* bytes, but the file on disk is NWCompressedBuffer framing — a 24-byte `NSYC` header then a zstd frame. `sha1sum <blob>` therefore never matches the name it is sitting under. The doc records the recipe that does match:
```
tail -c +25 <blob> | zstd -dc | sha1sum
```
Also notes the tree layout, that the uncompressed length is a little-endian `uint32` at offset 12, and the rough 4:1 compression ratio on hak content.
Verified two ways: against a real emit of a 250 MB hak (2296 blobs, 59 MB on disk against 249 MB of resources), and against `internal/nwsync/compressedbuf.go`, where the header is written as `[]uint32{blobMagic, blobVersion, algorithmZstd, uint32(len(data)), zstdHeaderVer, zstdDictionary}` — confirming field 3 at offset 12.
Docs only, no behaviour change. Falls out of the investigation in #76; that fix is not in this PR.

Builds the code half of #60, and closes the CLI gap the #53 sweep found: PR #71 shipped #53's original surface rather than the one #56, #62 and #65 settled.
## What lands
**`depot.KeyStore`** — `ProbeKey` / `PutReader` / `GetKey`, addressing the zone by object key rather than by depot sha. NWSync cannot use the sha-addressed path: a blob is named after the sha1 of its *uncompressed* bytes while the body uploaded is the compressed form, and Bunny's `Checksum` header is sha256 of the body. Per #55 this reuses `internal/depot`'s `httpBackend` — same IPv4-pinned transport, same retry, same tri-state probe — and the sha-addressed `Backend` is now rewritten on top of it. No second HTTP client, no per-instance hash-function fields: the caller passes the key and the checksum, which turned out simpler than #55 expected.
**A sink in `internal/nwsync`** — the zone by default, a local tree under `--out DIR` as the conformance path. Blobs upload as they are produced and the index lands last, so the presence of an index is the publication marker. A blob already in the zone is skipped via #55's probe *without* paying for compression (the body is a thunk) — which matters for the backfill, where compression is the expensive part.
**The settled CLI**
```
nwsync emit [--as NAME] [--out DIR] <artifact-key> <file>
nwsync assemble --group-id N [--tlk-key KEY] [--out DIR] <artifact-key>...
```
Artifact keys are depot keys; an index lives beside its artifact with the extension replaced (#62), derived in exactly one place so `emit` and `assemble` cannot disagree. Flags may now follow positionals — Go's `flag` stops at the first non-flag argument, which cost a run during #59.
**Fail-closed in two places** — an artifact key whose embedded digest does not match the file is refused (publishing an index under the wrong key silently pairs a manifest with the wrong artifact), and `assemble` refuses an artifact with no index rather than publishing a manifest missing a hak.
## Checks
`make check` green. Six new tests run against a Bunny-shaped `httptest` zone that verifies the `Checksum` header the way Bunny does: blobs-then-index ordering, skip-if-present, no index after a failed upload, key/file mismatch, and assemble reading indexes back out of the zone.
Conformance re-run through the new CLI against upstream `nwn_nwsync_write` 2.1.2 over `sow_vfxs_01.hak` (#59's oracle): the manifest is still **byte-identical**.
## Not in this PR
- **Live upload against the real zone.** The nwsync zone and its credential are #61, still open. Everything here is proven against a fake zone only.
- **Consumer wiring** — #65, in the three producer repos.
- **The mid-hak failure *policy*.** The mechanism is here (fail closed, orphan blobs left, re-run resumes); whether a module release may proceed when an emit failed is a human call, still open on #60.

Builds sow-tools#53. Format spec followed is the resolution comment of sow-platform#94, checked line by line against niv/neverwinter.nim at HEAD (`nwsync.nim`, `compressedbuf.nim`, `nwsync/private/libupdate.nim`).
## What lands
`crucible nwsync emit <artifact> --out DIR` — explodes one `.hak`/`.erf`, or one loose file such as the TLK, into NWSync blobs plus a NSYM v3 manifest covering only that artifact, with the same `.json` sidecar upstream writes. Blob path `data/sha1/<h0h1>/<h2h3>/<sha1>`, body in NWCompressedBuffer framing (magic `NSYC`, version 3, algorithm 2, uncompressed size, zstd header version 1, dictionary 0, raw zstd frame). The sha1 that names a blob is over the uncompressed bytes.
`crucible nwsync assemble --order NAMES --entries DIR --out DIR [--group-id N]` — merges the per-artifact manifests into one, reading no bulk data at all. Merge rule is resref shadowing, not concatenation: a resref in more than one artifact resolves to the earliest artifact in `--order`, which is how the game resolves it. `--group-id` stays caller-supplied (1 current, 2 testing; 0 is absent, matching upstream omitting a zero integer meta field).
Rules taken from upstream and not re-invented: `nss`/`ndb`/`gic` always skipped; an unresolvable restype is a hard error, not a skip; a resource over 15 MB fails closed; no `latest` file and no `.origin` file, ever. A `.mod` is refused outright — a persistent world publishes no module contents, so the module contributes no bytes.
## Two deliberate departures
- **Emitter version is its own field, not the build revision.** `emitter_version` is a constant bumped only when emitted bytes change. Keying the refuse-to-merge check on `created_with` would invalidate every published index on every unrelated crucible commit and force a re-emit of the whole 15 GB corpus — the opposite of "nothing downstream ever needs the hak again".
- **`SOURCE_DATE_EPOCH` pins the sidecar timestamp.** The manifest itself was already deterministic; the sidecar's `created` was not, against the determinism rule in `docs/consumer-contract.md`.
## Not in this PR, and why
- **Direct upload.** Only the local `--out` sink exists, which is the conformance path. The upload sink and the mid-hak-failure question are sow-tools#60, and the consumer wiring is #65.
- **The conformance run against upstream.** sow-tools#59 owns getting `nwn_nwsync_write` running and capturing reference output. The format here was read from upstream source rather than from its output, so the byte-for-byte manifest comparison and the after-decompression blob comparison still have to happen — that is what #59 is for. The tests in this PR check the layout against the spec, so a shared misreading would pass them.
- **The `artifacts/haks/sha256/<a>/<b>/<sha256>.nsym` location.** emit writes `<out>/<name>.nsym`; where a publisher puts it is the publisher's business (#65).
- **The acceptance gate** — a real client syncing from an assembled manifest — is unchanged and still open.
## Checks
`make check` green (vet, unit tests, shellcheck, yamllint, workflow contract), `make smoke` green with the new builder, `nix build .#crucible` produces `crucible-nwsync`.

`tea comment` reads stdin to EOF and appends whatever it finds to the comment body. In a non-interactive shell — which is every agent — stdin is an open pipe that never sends EOF, so the call hangs forever instead of posting.
Verified on tea 0.14.0: with `</dev/null` it posts instantly; with an open pipe it blocks until killed; with `echo "x" | tea comment N "y"` it posts `y` followed by `x`.

Closes#66.
`depot status` and `depot get` chose a depot tree on disk with `--target local`, taking the root from `DEPOT_DIR`. One decision, two flags — and `--target local` with no directory anywhere was valid but meaningless.
Now they take `--out DIR`, matching the crucible nwsync surface. `--target` names remote backends only (`bunny|cdn`). Passing both exits 64.
- `--target local` stays as a deprecated alias for `--out $DEPOT_DIR`, listed in the hidden-alias table in `docs/command-surface.md`. Nothing in `wrappers/` calls depot, but the three repos in `wrappers/consumers.txt` are out of reach from here, so the alias stays.
- `status --source` was already unused; it now warns "ignored; use --out DIR" instead of accepting silently.
- Fixes a real parse bug found on the way: the documented `depot get <sha> <dest> --target cdn` form never parsed its flags, because Go's `flag` package stops at the first positional. Positionals are split off by hand now; both orders are tested.
- Registry usage strings and `docs/command-surface.md` synced — that doc still said depot was unwired.
Not converted: `push --source` and `pull --dest`. Neither is `--target local`; one names a read source, the other a remote pull's destination. Say the word if they should become `--out` too.
`go test ./...` green.

## Summary
The `registry.westgate.pw/deployment/crucible` image has no consumer: `prod.yml` no longer reserves a slot for it (contract settled in sow-platform PR #64) and no runtime or recovery path pulls it. Binaries, wrappers, and the Nix input remain the supported ways to run Crucible.
## What changed
- Deleted `.gitea/workflows/build-image.yml`, `publish-image.yml`, `test-image.yml`
- Deleted `docker/Dockerfile` and the `make image` target
- Updated README, AGENTS.md, and `docs/consumer-contract.md` to state the image is retired
Existing `deployment/crucible` images in the registry can be deleted at leisure; nothing references them.
