[fix](trx-frontend-http): restore decode history from the stored records

Replay required every restored record to carry a string `type`, and
stored records do not have one: an AIS entry holds mmsi, lat, lon,
crc_ok and its decoder's own fields, nothing more.  The filter therefore
discarded all of them, and did it silently — the fetch returned its full
payload, the worker decoded it, and no error was logged, so the history
simply never appeared.

That field identifies live SSE frames, which do carry it, which is why
only replay was affected.  History arrives already grouped and the
group's kind is delivered alongside the messages, so `type` was never
needed to route them.  Require only that a record is an object.

Confirmed against a live server: the first restored group is AIS, and
its records expose their decoder fields with `type` undefined.

 ## Build and publish
 
+Nothing in the image is architecture-specific: the base image, the Debian build
+dependencies, Node.js, `rustup` and the `sccache` release all resolve per
+architecture, so the same `Containerfile` builds natively on x86_64 and arm64.
+
+Single architecture — the tag then only works on the architecture you built it
+on:
+
 ```bash
 # from the repo root
 podman build -t git.haxx.space/sjg/trx-rs/sdk:latest container

+**Both architectures without emulation.** The CI runner is x86_64 and Apple
+Silicon developer machines are arm64, so `:latest` has to be a manifest list —
+a single-architecture tag makes the other side fall back to Rosetta or qemu.
+Build each half natively on a host of that architecture, then join them:
+
+```bash
+# on an x86_64 host
+podman build --platform linux/amd64 -t git.haxx.space/sjg/trx-rs/sdk:latest-amd64 container
+podman push git.haxx.space/sjg/trx-rs/sdk:latest-amd64
+
+# on an arm64 host
+podman build --platform linux/arm64 -t git.haxx.space/sjg/trx-rs/sdk:latest-arm64 container
+podman push git.haxx.space/sjg/trx-rs/sdk:latest-arm64
+
+# from either, once both are pushed
+podman manifest create git.haxx.space/sjg/trx-rs/sdk:latest \
+  git.haxx.space/sjg/trx-rs/sdk:latest-amd64 \
+  git.haxx.space/sjg/trx-rs/sdk:latest-arm64
+podman manifest push --all git.haxx.space/sjg/trx-rs/sdk:latest
+```
+
+Building both from one machine is a single command
+(`podman build --platform linux/amd64,linux/arm64 --manifest ...`), but the
+foreign half runs under emulation and is slow — the two-host flow above is
+what keeps every build native.
+
 Tag with the Rust version too (e.g. `:1.97.1`) if you want reproducible pins.
 Make the package **public** (Gitea → Packages → the image → Settings) so the CI
 runner and developers can pull it without credentials. If you keep it private,
 add `credentials:` under the workflow's `container:` and log the runner into the
 registry.
 
+Pushing a rebuilt image is not enough on its own: `:latest` is a moving tag, and
+act_runner reuses whatever it cached the first time unless `force_pull: true` is
+set (see `runner-config.example.yaml`). Without it the job log says
+`Image exists? true` and the run behaves as though the image were never
+rebuilt — a tool added to the `Containerfile` reads as missing from the image.
+Either set `force_pull`, or refresh the VM's copy by hand:
+
+```bash
+docker pull git.haxx.space/sjg/trx-rs/sdk:latest
+docker run --rm git.haxx.space/sjg/trx-rs/sdk:latest sccache --version
+```
+
+### macOS note
+
+Apple's `container` CLI builds through a BuildKit helper VM that is configured
+with Rosetta whether or not the target is x86_64, so `container build` fails
+with *"Rosetta is not installed"* on a clean machine. That is a property of the
+builder, not of this image — `container run` works natively without it. Either
+install Rosetta once (`softwareupdate --install-rosetta`, after which an arm64
+build still produces a native arm64 image), or build with Podman, whose arm64
+BuildKit needs no emulation.
