An upload over a few MB came back as a 400 with an empty body, no message anywhere, and nothing logged
by Immich, the sidecar or officer. It was a race, not a size limit. Immich judges an asset from its
first few KB and rejects immediately, then closes; both our hops were still writing the body; Node
treats the leftover bytes as a protocol violation and replaces the application's answer with a bodyless
`400 Bad Request` + `Connection: close`. The real message never reached the wire.
Measured before the change: streamed lost the message 1/4 at 8 MB and 4/4 at 32 MB — probability rising
with size, which is why small photos usually worked and a phone's video never did.
Both hops needed it. Fixing only the sidecar took 32 MB from 4/4 failing to 2/4, because the platform
proxy was losing it one hop up.
Bounded at 512 MB, above which the body streams exactly as before. That ceiling is not a refusal and is
deliberately not a 413: a file Immich ACCEPTS is read to the end and never races, so a 4 GB video is
unaffected. All that is given up above the cap is the error message on a file that was going to be
rejected anyway. A first attempt refused over-cap uploads outright and would have broken the working
4 GB case to improve diagnosis of the doomed one.
`bufferRequestBody` is opt-in and off by default: the vault and wallet proxies must keep streaming so a
passphrase or macaroon never lands in the platform's heap.
Also adds the proxy error logging that made this findable at all — status and two byte counts from
headers, never the bodies. `responseBytes: "unknown"` is what exposed the stripped response.
Verified live at 32/256 MB (buffered) and 640 MB (streamed, passes through).

officer-photos owns the whole Immich contract: the instance URL and the API
key live there and nowhere else, and the platform side is an auth-gated
forwarder holding no credentials. The route surface is an allow-list keyed on
the first path segment, so admin, auth, api-keys, sessions, jobs, system-config
and libraries are unreachable by construction rather than by enumeration.
The UI mirrors Immich's own sidebar — timeline, explore, map, search, albums,
people, favorites, sharing, archive, trash — because the point of a sidecar
screen is to reproduce what the upstream already ships, then extend it. The
timeline reads Immich's columnar time-bucket format directly; selection lives
in the URL per docs/navigation-audit.md.
Two things worth knowing for anyone touching this later:
- `duration` is an integer count of milliseconds in Immich 3.0. It was an
HH:MM:SS.mmm string before, and every stale example still shows that form.
- the map container is sized with h-full/w-full, never `absolute inset-0`.
maplibre's stylesheet sets `position: relative; overflow: hidden` on the
element it is given, and an unlayered vendor rule beats Tailwind 4's layered
`.absolute` regardless of source order — so the div collapses to height 0 and
clips its own canvas away. Nothing errors: the GL context is healthy, tiles
download and pixels are drawn into a buffer nobody ever composites.
maplibre-gl is pinned to 5.x deliberately; 6.0 resolves a separate worker file
from import.meta.url, which Officer's index.html fallback answers with HTML.
