[fix](trx-server): persist all decoder histories

The runner image's `reuse` failed to import (NoEncodingModuleError): it
needs an encoding-detection backend, which the bare `reuse` install does
not provide and which libmagic/`file` is not present to satisfy. Install
`reuse[charset-normalizer]` so the reuse job can run in the image.

Rebuild the runner image and recreate the containers to pick this up.

+# Work In Progress — Project Improvement Areas
+
+Living tracker for engineering-infrastructure and hardening work identified
+during a July 2026 repo scan. The architecture-level backlog
+(`docs/Improvement-Areas.md`, P0–P3) is closed; these items focus on the
+tooling, robustness, and product concerns *around* the code.
+
+Status legend: **Done** · **In progress** · **Not started**
+
+| #  | Tier | Area | Status |
+|----|------|------|--------|
+| 1  | 1 — Infrastructure | Gitea Actions CI (fmt, clippy, test, REUSE) | In progress |
+| 2  | 1 — Infrastructure | Supply-chain & lint governance (cargo-deny/audit, MSRV, `[workspace.lints]`) | Not started |
+| 3  | 1 — Infrastructure | Release & deployment (container image, systemd units, binary releases) | Not started |

+| 5  | 2 — Robustness | `unsafe` SIMD safety scaffolding (`# Safety` docs, scalar↔SIMD equivalence tests) | Not started |
+| 6  | 2 — Robustness | DSP performance benchmarks (criterion, guard optimization gains) | Not started |

+| 9  | 3 — Product | Runtime observability (`/health`, Prometheus metrics) | Not started |
+| 10 | 3 — Product | Documentation freshness & consolidation (reconcile `docs/` with code) | Not started |
+
+## Tier 1 — Infrastructure gaps
+
+### 1. Gitea Actions CI
+No `.gitea/` / `.github/` / Woodpecker workflows exist, despite 768 tests.
+Add a workflow running `cargo fmt --check`, `cargo clippy -D warnings`,
+`cargo build`/`cargo test`, and REUSE lint on push + pull_request.
+System deps: `pkg-config cmake libopus-dev libasound2-dev libsoapysdr-dev`
+(the `soapysdr` backend is a default feature).
+
+Notes for the runner: assumes an `act_runner` registered with an
+`ubuntu-latest` label and GitHub-action proxying enabled (used by
+`actions/checkout`, `actions/cache`, `fsfe/reuse-action`). `clippy` runs
+with `-D warnings`; core crates are already clean, but if the first full
+`--all-features` run surfaces warnings in a less-travelled crate, fix them
+(preferred) or temporarily soften that step.
+
+### 2. Supply-chain & lint governance
+No `deny.toml`, `cargo audit`, `rustfmt.toml`/`clippy.toml`, declared MSRV,
+or `[workspace.lints]`. Add dependency auditing to CI, pin an MSRV
+(`rust-version`), and centralize lint policy in the workspace manifest.
+
+### 3. Release & deployment
+No `Dockerfile`, systemd units, packaging, or release automation (only
+`script/dummy-server.sh`). Add a container image, example systemd units for
+`trx-server`/`trx-client`, and a tag-triggered static-binary release job.
+
+## Tier 2 — Robustness & correctness
+
+### 4. Panic-resilience audit
+495 `unwrap()`/`expect()`/`panic!` sites, 11 in the hottest server files
+(`audio.rs`, `rig_task.rs`). A panic there can drop a rig task or the
+process. Convert hot-path panics to error propagation / graceful
+degradation; reserve `expect` for documented invariants.
+
+### 5. `unsafe` SIMD safety scaffolding
+13 `unsafe` blocks (AVX2 DSP). Add `# Safety` docs stating invariants,
+confirm runtime feature detection is tested, and add property tests
+asserting SIMD output matches the scalar fallback across random inputs.
+
+### 6. DSP performance benchmarks
+`docs/Optimization-Guidelines.md` documents NCO/polyphase/AVX2 gains, but no
+`criterion` benches guard them. Add benches for the demod/resample/FFT hot
+paths so regressions surface as numbers.
+
+### 7. Test-coverage measurement & gap-filling
+67 of 146 Rust files have no test module. Protocol is well covered; backends
+(CAT BCD/ASCII encoding), `listener.rs`, and `config.rs` look thin. Wire up
+`cargo-llvm-cov` and target the CAT backends and server tasks first.
+
+## Tier 3 — Product & maintainability
+
+### 8. Frontend modularization & tooling
+`app.js` is 8,760 lines and `map-core.js` 3,515, with no modules, linter, or
+tests. Keeping vanilla HTML+JS (no framework), split into native ES modules
+by concern, add ESLint + Prettier, and add `node:test` unit tests for pure
+logic (frequency formatting, unit math, decode parsing).
+
+### 9. Runtime observability
+`tracing` is set up, but there is no `/health` endpoint or metrics
+instrumentation. Add health/readiness endpoints and Prometheus-format
+metrics (decode rates, reconnects, audio underruns, per-rig state).
+
+### 10. Documentation freshness & consolidation
+`docs/` (13 files) is mostly dated 2026-03-29 while code moved into July, and
+mixes planning artifacts with reference docs. Reconcile against current code,
+separate "plans" from "reference," and fold still-true content into the
+canonical docs.

+# Podman-based Gitea Actions runners
+
+Run two independent Gitea Actions runners on one host as rootless Podman
+containers managed by systemd (Quadlet) — one per project — instead of two
+VMs. Uses the **host executor**: workflow steps run directly inside a
+purpose-built runner image that already has the Rust toolchain and all build
+dependencies baked in, so CI runs skip the per-run install cost and no
+Docker/Podman socket is needed.
+
+## Files
+
+| File | Purpose |
+|------|---------|
+| `Containerfile` | Runner image: Debian + build deps + clang + Rust + Node + `reuse` + `act_runner`. |
+| `entrypoint.sh` | Registers on first boot (if needed), then runs the daemon. |
+| `config.yaml` | act_runner config template (seeded into each runner's volume). |
+| `trx-rs-runner.container` | Quadlet unit for the trx-rs runner. |
+| `project2-runner.container` | Quadlet unit for the second project's runner. |
+
+## Prerequisites (once per host)
+
+Rootless Podman with cgroups v2 (default on modern distros). As the unprivileged
+user that will own the runners:
+
+```bash
+# Survive logout / start on boot without an interactive session.
+loginctl enable-linger "$USER"
+```
+
+No `podman.socket` is required for the host executor.
+
+## 1. Build the image
+
+```bash
+cd container
+podman build -t trx-rs-ci:latest .
+```
+
+## 2. Get a registration token
+
+For **each** repo: *Settings → Actions → Runners → Create new Runner* and copy
+the token. (Org- or instance-level tokens work too if you prefer wider scope.)
+
+## 3. Install and start the runners
+
+```bash
+mkdir -p ~/.config/containers/systemd
+cp trx-rs-runner.container project2-runner.container ~/.config/containers/systemd/
+
+# Paste each repo's token for the FIRST boot only:
+#   Environment=GITEA_RUNNER_REGISTRATION_TOKEN=xxxx…
+$EDITOR ~/.config/containers/systemd/trx-rs-runner.container
+$EDITOR ~/.config/containers/systemd/project2-runner.container
+
+systemctl --user daemon-reload
+systemctl --user start trx-rs-runner
+systemctl --user start project2-runner
+
+systemctl --user status trx-rs-runner
+podman logs -f gitea-runner-trx-rs
+```
+
+Once each runner shows **online** in the repo's runner list, blank out the
+`GITEA_RUNNER_REGISTRATION_TOKEN` line again (the registration is persisted in
+the `…-data` volume) and `systemctl --user daemon-reload`.
+
+## Required workflow change: the `reuse` job
+
+The host executor runs steps directly in the container and therefore **cannot
+run Docker-based actions**. The current `reuse` job uses `fsfe/reuse-action@v5`,
+which is a Docker action. `reuse` is baked into the image, so replace that job
+with a plain command:
+
+```yaml
+  reuse:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - name: REUSE compliance
+        run: reuse lint
+```
+
+The `lint` and `test` jobs need no changes: their `sudo apt-get …` and rustup
+steps still run, but become fast no-ops because the image already has those
+packages and the toolchain. (`sudo` is included in the image for exactly this
+reason.)
+
+> If you would rather keep Docker-based actions and per-run images, use the
+> **Docker executor** instead: drop the `:host` suffix from the label in
+> `config.yaml`, enable `systemctl --user --now enable podman.socket`, mount it
+> into the container, and set `container.docker_host` to the socket path. That
+> trades the baked-in speed for stronger per-job isolation.
+
+## Tuning
+
+- **`capacity`** (in `config.yaml`) — concurrent jobs per runner. Rust builds
+  are heavy; 1–2 is sensible when two runners share a host.
+- **`PodmanArgs=--cpus/--memory`** (in each `.container`) — hard resource caps
+  so one project cannot starve the other.
+- **SELinux** — the `:Z` volume flag is already set; keep it if SELinux is
+  enforcing.
+
+## Committing these files
+
+If you add this directory to a REUSE-checked repo, register the markdown in
+`REUSE.toml` (the other files carry inline SPDX headers):
