[feat](trx-sstv): decode SSTV pictures

A new decoder crate covering the modes SSTV is actually sent in: Martin
M1/M2, Scottie S1/S2/DX, Robot 36/72, PD50 through PD290, and Wraase
SC2-180.  The mode comes from the VIS header every transmission opens
with, so nothing has to be told what is arriving.

Modes are a table rather than code: a list of segments -- sync, gaps,
and one scan per colour channel -- plus a colour model and a geometry.
The decoder reads the offset of each scan straight off that list, which
is what makes fifteen modes cost about as much as one, and a new mode a
table entry.  The segment lists are checked against the published line
durations in a test, because both are transcribed by hand from the same
specification and a digit wrong in one is unlikely to be wrong
identically in the other.

Signal path: band-pass over the SSTV band, Hilbert FIR, instantaneous
frequency by phase difference, then a state machine that walks the
transmission a line at a time.  Each line is looked for where the mode
says it should be and nudged into place by the sync pulse found near
it -- two sound cards never agree exactly, and over the two minutes of a
Martin M1 frame an uncorrected error of a few parts per million shears
the picture visibly.  Rows are emitted as they decode, so a picture can
be watched arriving, which is most of the appeal of the mode.

Four things this cost, each now the reason a piece of it is shaped the
way it is:

The per-sample frequency estimate ripples by ±95 Hz at 1200 Hz, where
the Hilbert approximation is weakest, though its mean is exact.  Pixels
average over their own window and were always right; the VIS bits and
the sync detector classify individual samples and were reading the
ripple.  Both now read short means.  Pixels deliberately still do not,
so edges stay where they are.

Broadband noise cost the whole picture, not part of it: a
phase-difference detector answers whatever is loudest, and there was no
input filter.  Hence the band-pass, which is what every real decoder
does first.

A sync search window shorter than a sync pulse rejected every pulse
arriving late in it, for being short.

The first line's sync search locked onto the VIS stop bit -- 30 ms at
exactly the sync frequency, immediately before the picture starts.  The
header already says where the picture begins, so the first line no
longer searches.

Tests: nine modes are encoded from a test card and decoded back,
compared pixel by pixel, alongside silence around the signal, a
transmission cut off part way, two transmissions back to back, 20 dB of
noise, and a transmitter clock 0.1% fast.  The encoder that produces
those signals reads the same table as the decoder, so a round trip
tests the decoder and not the timings; the timings are held to the
published line durations separately.

Nothing is wired into the server or the web UI yet: this is the decoder
alone.

+APRS symbol set (https://github.com/hessu/aprs-symbols)
+=========================================================
+
+Verbatim copy of the upstream COPYRIGHT.md, retrieved 2026-08-03 from
+https://github.com/hessu/aprs-symbols.  The set has no single SPDX license:
+individual symbols carry different terms, summarized below.  Attribution

+provide a pointer to the source (http://github.com/hessu/aprs-symbols/)."
+
+---
+
+
+Copyright and licensing information
+======================================
+
+This is a collection of vectorized symbols for use on the APRS system.
+
+The copyright status of this collection is a bit complicated, since the
+symbols come from various sources, each having different copyright owners.
+
+Most of the vectorized symbols are loosely based on the low-resolution
+"standard" bitmap symbol set as distributed by Stephen Smith, WA8LMF.  That
+set is used by most APRS software around the world.  The low resolution of
+those symbols does not allow direct vector conversion, so I've drawn new
+symbols in a similar layout.  The vector versions try to mimic the original
+appearance and colours, with the intention of keeping the set recognizable
+and familiar to existing users.  In some cases the vector versions are
+probably similar enough to the originals, so that they cannot be considered
+"original work" by myself.  In some of these cases, the originals are
+probably also mimicking someone else's design.
+
+The original symbols do not come with any information on their licensing.
+They've been distributed with a lot of APRS software over time, but I don't
+know who designed which symbol originally. Most likely all of them are
+drawn by one of:
+
+  * Roger Barker, G4IDE, "original set provided with UI-View" (SK)
+  * Steve Dimse, KH4G, "U.S. customary set"
+  * Stephen Smith, WA8LMF
+
+The Adobe Illustrator (.ai) file contains a copy of the original bitmaps
+as a hidden layer, just for reference.
+
+Some symbols I obtained from other sources, such as Wikipedia. In those
+cases I picked SVG versions which allow commercial reuse (source known, and
+the work is placed on public domain, or with a CC license which allows
+adaptation and commercial reuse).
+
+Some symbols are vectorized versions of product or brand logos. The
+copyright of those is owned by the respective companies (Apple, Microsoft,
+Kenwood), and each of those may have some opinions on how the logos are
+used.  Please check for yourself if you can use them or not.
+
+In the list below I try to summarize the licensing status for each symbol.

-Run two independent Gitea Actions runners on one host as rootless Podman
+A single container image that is the canonical build environment for trx-rs,
-containers managed by systemd (Quadlet) — one per project — instead of two
+used **both** by CI and by developers. It bakes in the pinned Rust toolchain
-VMs. Uses the **host executor**: workflow steps run directly inside a
+(matching `rust-toolchain.toml`) and every build dependency, so the compiler
-purpose-built runner image that already has the Rust toolchain and all build
+and `clippy` are identical everywhere — no "works on my machine".
-dependencies baked in, so CI runs skip the per-run install cost and no

-## Files
 
 | File | Purpose |
 |------|---------|
-| `Containerfile` | Runner image: Debian + build deps + clang + Rust + Node + `reuse` + `act_runner`. |
+| `Containerfile` | The SDK image (Debian + build deps + pinned Rust + Node + git). |
-| `entrypoint.sh` | Registers on first boot (if needed), then runs the daemon. |
+| `runner-config.example.yaml` | Example act_runner config for the CI VM (Docker executor). |
-| `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)
+## Build and publish
 
-Rootless Podman with cgroups v2 (default on modern distros). As the unprivileged
+Nothing in the image is architecture-specific: the base image, the Debian build
-user that will own the runners:
+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
-# Survive logout / start on boot without an interactive session.
+# from the repo root
-loginctl enable-linger "$USER"
+podman build -t git.haxx.space/sjg/trx-rs/sdk:latest container
+podman login git.haxx.space
+podman push git.haxx.space/sjg/trx-rs/sdk:latest
 ```
 
-No `podman.socket` is required for the host executor.
+**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 —
-## 1. Build the image
+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
-cd container
+# on an x86_64 host
-podman build -t trx-rs-ci:latest .
+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
 ```
 
-## 2. Get a registration token
+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.
 
-For **each** repo: *Settings → Actions → Runners → Create new Runner* and copy
+Tag with the Rust version too (e.g. `:1.97.1`) if you want reproducible pins.
-the token. (Org- or instance-level tokens work too if you prefer wider scope.)
+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.
 
-## 3. Install and start the runners
+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
-mkdir -p ~/.config/containers/systemd
+docker pull git.haxx.space/sjg/trx-rs/sdk:latest
-cp trx-rs-runner.container project2-runner.container ~/.config/containers/systemd/
+docker run --rm git.haxx.space/sjg/trx-rs/sdk:latest sccache --version
-
-# Paste each repo's token for the FIRST boot only:

-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
+### macOS note
-`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
+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.
 
-The host executor runs steps directly in the container and therefore **cannot
+## Developer use
-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
+Reproducible one-off build, no local toolchain needed:
-  reuse:
+
-    runs-on: ubuntu-latest
+```bash
-    steps:
+podman run --rm -it -v "$PWD":/work -w /work \
-      - uses: actions/checkout@v4
+  git.haxx.space/sjg/trx-rs/sdk:latest \
-      - name: REUSE compliance
+  cargo build --release
-        run: reuse lint
 ```
 
-The `lint` and `test` jobs need no changes: their `sudo apt-get …` and rustup
+Or open the repo in the image via VS Code / JetBrains "Reopen in Container"
-steps still run, but become fast no-ops because the image already has those
+(`.devcontainer/devcontainer.json` points at the same image).
-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
+Building outside the container? `rust-toolchain.toml` pins the same rustc, so
-> **Docker executor** instead: drop the `:host` suffix from the label in
+`rustup` installs the matching toolchain automatically.

-## Tuning
+## CI use
 
-- **`capacity`** (in `config.yaml`) — concurrent jobs per runner. Rust builds
+`.gitea/workflows/ci.yml` runs the `lint`, `test` and `frontend` jobs *inside*
-  are heavy; 1–2 is sensible when two runners share a host.
+this image via the `container:` key, so they skip all setup and go straight to
-- **`PodmanArgs=--cpus/--memory`** (in each `.container`) — hard resource caps
+`cargo` and `npm`. The frontend job needs three things from the image beyond
-  so one project cannot starve the other.
+Rust: Node.js for the toolchain, Chromium at `/usr/bin/chromium` for the
-- **SELinux** — the `:Z` volume flag is already set; keep it if SELinux is
+browser smoke test, and `cargo` — `npm run verify-generated` regenerates the
-  enforcing.
+Rust wire contracts before checking for drift.
 
-## Committing these files
+The `reuse` job stays on the upstream `fsfe/reuse-action` (a Docker action the
+Docker executor launches as a sibling container) — nothing REUSE-related is
+baked into the SDK, and it lints the whole repository, so no job runs its own
+licence check.
 
-If you add this directory to a REUSE-checked repo, register the markdown in
+## Compilation cache (sccache)
-`REUSE.toml` (the other files carry inline SPDX headers):
 
-```toml
+The SDK image ships [`sccache`](https://github.com/mozilla/sccache). It is
-[[annotations]]
+enabled via `RUSTC_WRAPPER=sccache` in CI and the devcontainer (not repo-wide,

+so plain `cargo` builds outside the SDK are unaffected).

+- **CI** persists the cache on the runner host — create the dir once:
+  `mkdir -p /var/cache/sccache`. It is bind-mounted into each job container at
+  `/sccache` (see `runner-config.example.yaml`), so cache survives across runs
+  and is shared between the lint/test jobs and both projects.
+- **Devcontainer** uses a named volume (`trx-rs-sccache`).
+- Check effectiveness with `sccache --show-stats` (the CI jobs print it).
+
+`CARGO_INCREMENTAL=0` is set wherever sccache is on, since sccache cannot cache
+incremental artifacts.
+
+## CI runner (Alpine / OpenRC)
+
+The runner uses the **Docker executor** (not the host executor): per-job
+container isolation and standard `ubuntu-latest` semantics. `act_runner` runs
+as an OpenRC service. Files provided:
+
+| File | Purpose |
+|------|---------|
+| `act_runner.openrc` | OpenRC init script (`supervise-daemon`, depends on docker). |
+| `act_runner.confd.example` | Per-instance `conf.d` settings for multi-runner hosts. |
+
+**Cap the thread budget.** In a VM, pin its vCPUs to specific host threads
+(libvirt/KVM):
+
+```xml
+<vcpu placement='static'>2</vcpu>
+<cputune>
+  <vcpupin vcpu='0' cpuset='4'/>
+  <vcpupin vcpu='1' cpuset='5'/>
+</cputune>
 ```
+
+On bare metal, the `container.options: "--cpus=2"` and `capacity: 1` in
+`runner-config.example.yaml` already bound each runner.
+
+**Set it up:**

+

+```
+
+| Parameter | Meaning |

+| `f` | Frequency. Hz by default; `7074k` and `14.074M` also work. |
+| `mode` | Demodulation mode, e.g. `USB`, `CW`, `WFM`. |
+| `bw` | Filter bandwidth in Hz. Ignored by rigs without filter control. |
+| `rig` | Rig to select first, by id, on a multi-rig client. |
+
+Opening such a link selects the rig, sets the mode, tunes, and applies the
+bandwidth, in that order — a mode change carries its own default bandwidth, so
+an explicit `bw` is applied last. Anything the rig cannot do (an unknown mode,
+a frequency outside its range) is reported and the rest of the link still
+applies. All four parameters are optional.
+
+The link button in the top bar copies the current link to the clipboard. The
+address bar itself is updated as you tune, using `replaceState`, so sweeping
+the dial does not fill the browser's history.
+
+Applying a link changes the radio, so it needs the `control` role; an `rx`
+session opens the page and says the link was not applied. Links describe the
+rig's own dial — while a tab is listening to a virtual channel the address is
+left as it was, rather than publishing a frequency the rig is not on.

+
+# Frontend architecture
+
+The HTTP frontend is a strict TypeScript application built with esbuild. Rust
+embeds deterministic JavaScript output from `assets/web/generated`; Cargo does
+not run Node.js or contact the network.
+
+## Runtime graph
+
+`frontend/src/bootstrap.ts` is the only first-party script referenced by the
+HTML document. Its imports establish startup order for WebGL support, shared UI
+services, decoder dispatch, the local Leaflet AIS adapter, and the application
+coordinator. Leaflet and the Opus decoder remain isolated vendored scripts.
+
+Feature entries under `frontend/src/plugins` are ESM bundles. The typed plugin
+loader imports them by feature group and keeps expensive map, scheduling, and
+decoder behavior lazy. Shared code is emitted as content-hashed chunks. The
+decode-history worker is an independent entry compiled against Web Worker
+globals.
+
+Dependencies point from application and feature code toward `core` and `api`.
+`api/generated.ts` contains Rust wire formats; `api/client.ts` and focused
+parsers validate untrusted HTTP, SSE, WebSocket, and worker data before it is
+used as typed application state.
+
+## Browser host contract
+
+Separate lazy bundles cannot share module instances with the stable application
+entry, so they use three intentional host namespaces:
+
+| Global | Purpose | Mutation policy |
+| --- | --- | --- |
+| `window.trx` | Application state, core services, and feature registrations | The root is frozen; lazy features may register only their documented `modules.*` service. |
+| `window.trxPluginRuntime` | Typed decoder registration and message dispatch | Runtime object is installed once; plugins register lifecycle handlers through its API. |
+| `window.trxUi` | Notifications, confirmations, tab accessibility, and control presentation | Installed once by `ui-core.ts`; consumers call methods but do not replace them. |
+
+`frontend/src/plugins/host.ts` declares the typed view of `window.trx.state`
+and `window.trx.core` that feature bundles consume. Feature entries import it
+instead of re-deriving the contract, so a service that moves out of the
+application entry is added in one place. Application state that a feature needs
+belongs in `trx.state`, and shared behavior belongs in `trx.core`; a feature
+that has to intercept application behavior registers a `modules.*` method the
+application calls, as the virtual-channel entry does for tuning, mode,
+bandwidth, and frequency display.
+
+The WebGL adapter exposes `createTrxWebGlRenderer`, `trxParseCssColor`,
+`trxHslToRgba`, and `trxClearCssColorCache` for the application bundle. Leaflet
+adds `L.TrxAisTrackSymbol` and `L.trxAisTrackSymbol` to the vendored Leaflet
+namespace.
+
+The following transitional properties are explicitly part of the lazy-feature
+host contract and are declared in `app.ts`: `lastSpectrumData`, `lastFreqHz`,
+`currentBandwidthHz`, `ft8BaseHz`, `getDecodeHistoryRetentionMs`,
+`applyDecodeHistoryRetention`, `getDecodeRigMeta`, `renderRdsOverlays`,
+`buildAisVesselUrl`, `trxScheduleUiFrameJob`,
+`takeSchedulerControlForDecoderDisable`, `navigateToTab`, `_syncRecorderState`,
+and `refreshRdsUi`. Optional callbacks owned by lazy features are
+`refreshCwTonePicker`, `updateFt8RfDisplay`, `clearSatPredictionDom`,
+`syncWefaxToggle`, `updateAisBar`, `updateVdesBar`, `updateAprsBar`,
+`updateFt8Bar`, `updateSatLiveState`, `applyCwAutoUi`, and
+`applyCwAutoUiFromServer`.
+
+This list is closed: new standalone mutable `window` properties are not an
+accepted integration mechanism. Extend an existing typed service or introduce
+an imported interface instead. Removing transitional properties as feature
+boundaries become directly importable remains preferable.
+
+## Build and verification
+
+The generated directory is removed before every build, preventing orphaned
+compatibility bundles. Stable feature entry names are allowlisted by the Rust
+asset manifest; shared chunks use content hashes. The generic Rust handler
+rejects unknown names and unsupported MIME types and serves embedded assets
+with compression, ETags, and immutable caching.
+
+CI installs from `package-lock.json`, caches only npm downloads, type-checks the
+window and worker environments separately, lints, runs unit and DOM tests,
+starts the application in Chromium, regenerates Rust contracts and bundles,
+checks for drift, and runs REUSE validation after generation.
+
+See `frontend/src/README.md` for local commands and
+`docs/ts-migration-plan.md` for the migration decisions and completion gates.

+# TypeScript migration baseline
+
+This baseline records the browser architecture at the start of the migration.
+It is intentionally historical; generated output sizes are tracked separately
+by the deterministic frontend build.
+
+## Startup order
+
+The initial document loads these scripts in order:
+
+1. `/vendor/opus-decoder-0.7.11.min.js`
+2. `/vendor/leaflet.js`
+3. `/leaflet-ais-tracksymbol.js`
+4. `/webgl-renderer.js`
+5. `/ui-core.js`
+6. `/app.js`
+
+Decoder and feature scripts are then loaded lazily by the inline loader in
+`index.html`. The frontend smoke test locks the core ordering and rejects
+remote script or stylesheet URLs.
+
+## Source measurements
+
+At baseline, first-party JavaScript comprised 23 files and approximately
+776 KiB. The largest sources were:
+
+| Source | Bytes |
+|---|---:|
+| `app.js` | 337,111 |
+| `map-core.js` | 131,899 |
+| `plugins/scheduler.js` | 60,883 |
+| `plugins/bookmarks.js` | 30,543 |
+| `plugins/sat.js` | 22,541 |
+| `plugins/vchan.js` | 20,195 |
+| `webgl-renderer.js` | 18,993 |
+
+The migrated source snapshot contained 123 distinct direct `window.*`
+assignments. These are compatibility callbacks, shared state, and plugin entry
+points. New TypeScript code must not add to that set; the typed plugin registry
+and explicit services replace it over the course of the migration.
+
+All production scripts, stylesheets, fonts, icons, and map assets were already
+served from local embedded routes. The automated startup test ensures no
+remote runtime script or stylesheet dependency is introduced.

+# TypeScript Migration Plan
+
+> **Scope**: `src/trx-client/trx-frontend/trx-frontend-http/`
+>
+> **Status**: Complete (2026-08-01)
+
+## Implementation result
+
+The migration was completed on `feat/typescript-frontend-migration`. The
+baseline and phased sections below are retained as the decision record; their
+descriptions of JavaScript files and classic loading refer to the pre-migration
+state.
+
+Completion evidence:
+
+- all first-party browser sources are strict `.ts` files, checked by separate
+  DOM and Web Worker TypeScript projects with no JavaScript compatibility mode
+  or suppression directives;
+- `bootstrap.ts` is the single first-party HTML entry and esbuild represents
+  startup order, lazy feature imports, shared hashed chunks, and the worker in
+  its module graph;
+- obsolete source and generated compatibility JavaScript was removed;
+- Rust generates rig, status, capability, decoder, and flattened frontend
+  metadata contracts into `api/generated.ts`; runtime guards validate HTTP,
+  SSE, WebSocket, and worker boundaries;
+- the generic embedded-asset handler serves a build-generated allowlist with
+  constrained MIME types, compression, ETags, immutable caching, and no file
+  system lookup;
+- intentional browser host namespaces and transitional lazy-feature properties
+  are documented in `docs/frontend-architecture.md`;
+- CI uses locked npm dependencies, caches npm downloads rather than
+  `node_modules`, runs strict type checking and linting, unit/DOM/worker tests,
+  Chromium startup coverage, generated-output drift checks, and REUSE after
+  generation;
+- Cargo continues to consume committed generated assets without invoking Node
+  or requiring network access.
+
+The final local gate ran `npm ci`, type checking, linting, 30 frontend tests,
+the Chromium smoke flow (startup, auth gate, audio controls, rig switching, map
+initialization, and navigation), generated-contract and bundle verification,
+workspace formatting, Clippy with warnings denied, all-target builds, workspace
+tests, and REUSE 3.3 validation.
+
+## 1. Decision
+
+Migrating the web frontend to TypeScript is worthwhile, provided it is used to
+remove implicit contracts and global coupling. Renaming JavaScript files to
+`.ts` without changing their boundaries would add tooling without delivering
+the main safety benefits.
+
+The migration must be incremental. Every intermediate commit and pull request
+must leave the frontend buildable and usable.
+
+## 2. Baseline State
+
+The frontend currently contains roughly 21,700 lines of first-party
+JavaScript. Its largest components include:
+
+- `app.js`: approximately 8,900 lines;
+- `map-core.js`: approximately 3,500 lines;
+- `plugins/scheduler.js`: approximately 1,500 lines;
+- `plugins/bookmarks.js`: approximately 800 lines;
+- `plugins/vchan.js`: approximately 560 lines.
+
+Important characteristics of the current architecture are:
+
+- scripts are embedded individually into the Rust binary with `include_str!`;
+- the Rust HTTP server exposes an explicit route for each asset;
+- plugins are loaded dynamically as classic scripts;
+- script order is significant;
+- modules communicate through `window.*`, `window.trx`, callbacks, and shared
+  mutable state;
+- the main HTML file contains the plugin loader;
+- a Web Worker is loaded through a fixed URL;
+- Cargo builds do not require Node.js;
+- CI images contain Node.js, but CI currently runs only Rust and REUSE checks;
+- Leaflet, Opus decoder, fonts, images, and other vendored assets are local.
+
+These constraints make a big-bang rewrite unnecessarily risky.
+
+## 3. Goals
+
+The migration should:
+
+1. Create checked contracts between Rust responses and browser code.
+2. Replace global callbacks with explicit module interfaces.
+3. Split `app.js` by responsibility.
+4. Make rig, capability, decoder, scheduler, audio, and spectrum state explicit.
+5. Preserve lazy loading for expensive features.
+6. Add frontend type checking, linting, and automated tests to CI.
+7. Keep ordinary Cargo builds independent of Node.js and network access.
+8. Preserve existing browser behavior throughout the migration.
+
+## 4. Non-Goals
+
+The migration will not initially:
+
+- introduce a UI framework;
+- redesign the user interface;
+- convert vendored JavaScript to TypeScript;
+- change REST, SSE, WebSocket, or worker protocols unless required to make an
+  existing contract unambiguous;
+- make `build.rs` install packages or download frontend dependencies;
+- convert all of `app.js` in one pull request.

+```
+
+The exact feature directories may evolve, but dependencies should point from
+features toward `core` and `api`, never from `core` back into features.
+
+## 6. Tooling
+
+Use TypeScript for type checking and esbuild for bundling. A framework-specific
+development server is not needed.
+
+Recommended compiler baseline:
+
+```json
+{
+  "compilerOptions": {
+    "target": "ES2022",
+    "module": "ESNext",
+    "moduleResolution": "Bundler",
+    "strict": true,
+    "noUncheckedIndexedAccess": true,
+    "exactOptionalPropertyTypes": true,
+    "useUnknownInCatchVariables": true,
+    "noEmit": true,
+    "lib": ["ES2022", "DOM"]
+  }
+}
+```
+
+Worker code should use a separate configuration with `WebWorker` rather than
+`DOM` globals.
+
+The package scripts should provide at least:
+
+```text
+npm run typecheck
+npm run lint
+npm test
+npm run build
+npm run verify-generated
+```
+
+Pin dependencies in `package-lock.json`. New package and generated files must
+carry or inherit valid REUSE licensing information.
+
+## 7. Cargo and Asset Integration
+
+Cargo must remain usable on machines without Node.js. Do not invoke `npm`
+automatically from `build.rs`.
+
+The initial integration should work as follows:
+
+1. TypeScript and JavaScript sources live under `frontend/src`.
+2. esbuild writes browser-ready output under `assets/web/generated`.
+3. Generated browser output is committed to the repository.
+4. Rust embeds generated output, not TypeScript source.
+5. CI rebuilds the frontend and fails if committed output is stale.
+
+During early phases, retain the existing public URLs, including:
+
+```text
+/app.js
+/ui-core.js
+/map-core.js
+/scheduler.js
+/decode-history-worker.js
+```
+
+Keeping these URLs stable avoids coupling the first migration phases to changes
+in HTML loading, authentication rules, caching, or Rust routing.
+
+After modules and code splitting are established, replace the explicit list of
+Rust constants and handlers with an embedded generated-asset directory. The
+server must still enforce an allowlist, correct MIME types, cache headers, and
+path traversal protection.
+
+## 8. Rust-to-TypeScript Contracts
+
+Generate TypeScript definitions from Rust wire types instead of maintaining
+parallel handwritten representations.
+
+Initial candidates include:
+
+- `RigState`, `RigInfo`, and `RigCapabilities`;
+- the `/rigs` response;
+- decoder registry entries;
+- scheduler configuration and status;
+- filter and spectrum state;
+- recorder responses;
+- SSE update payloads;
+- decoded-message variants;
+- WebSocket control and status messages.
+
+A generator such as `ts-rs` can produce
+`frontend/src/api/generated.ts`. Generated definitions should describe only
+wire formats. UI state and view models should remain handwritten.
+
+CI must regenerate these definitions and fail when the working tree changes.
+Serde renames, tagged enums, optional fields, flattened values, and numeric
+ranges must be checked explicitly during the initial generator integration.
+
+TypeScript types do not validate data at runtime. Critical compatibility
+boundaries should retain focused runtime checks for missing or malformed data,
+particularly when clients and servers may run different versions.
+
+## 9. Target Module Contracts
+
+Plugins should eventually implement an explicit interface rather than assigning
+callbacks to `window`:
+
+```ts
+interface TrxPlugin {
+  readonly id: string;
+  initialize(context: PluginContext): void | Promise<void>;
+  dispose?(): void;
+}
+
+interface PluginContext {
+  api: TrxApi;
+  events: TrxEventBus;
+  navigation: NavigationService;
+  notifications: NotificationService;
+  state: ReadonlyRadioState;
+}
+```
+
+During the transition, `legacy/global-bridge.ts` may expose the minimum globals
+required by unmigrated scripts. The bridge must shrink as migration progresses;
+new feature code must not add new global callbacks.
+
+State should be divided by responsibility rather than replaced by one large
+typed global:
+
+```ts
+interface RadioState {
+  activeRigId: string | null;
+  capabilities: RigCapabilities | null;
+  connection: ConnectionState;
+  frequencyHz: number | null;
+  mode: RigMode | null;
+  bandwidthHz: number | null;
+}
+
+interface AudioState {
+  rx: AudioStreamState;
+  tx: AudioStreamState;
+  volume: VolumeState;
+}
+
+interface DecoderState {
+  registry: DecoderDescriptor[];
+  status: ReadonlyMap<DecoderId, DecoderStatus>;
+}
+```
+
+Commands should receive a rig ID explicitly. They must not infer their target
+from mutable global selection state after an asynchronous operation begins.
+
+## 10. Migration Phases
+
+### Phase 0: Baseline and Measurements
+
+- Record current asset names, sizes, and load order.
+- Add a browser startup smoke test.
+- Record existing global symbols and plugin callbacks.
+- Confirm that generated bundles do not introduce remote runtime dependencies.
+
+**Exit criterion:** current behavior and asset loading have an automated
+baseline.
+
+### Phase 1: Tooling Scaffold
+
+- Add the frontend package, lockfile, TypeScript configuration, and esbuild.
+- Allow existing JavaScript as build input without type checking it globally.
+- Produce fixed-name outputs matching current URLs.
+- Add frontend commands and CI checks.
+- Document local frontend development commands.
+
+**Exit criterion:** existing JavaScript passes through the frontend build with
+no runtime changes, and CI detects stale generated output.
+
+### Phase 2: Generated API Types
+
+- Add Rust-to-TypeScript type generation.
+- Generate the first status, rig, capability, and decoder contracts.
+- Introduce a typed fetch/post client and typed SSE decoding boundary.
+- Keep narrow runtime guards at compatibility boundaries.
+
+**Exit criterion:** new API consumers cannot use untyped response objects.
+
+### Phase 3: Core Browser Services
+
+Convert or create:
+
+- DOM lookup helpers;
+- notifications and confirmations;
+- settings and per-rig preferences;
+- navigation;
+- the event bus;
+- application state stores;
+- plugin registry and loader.
+
+Convert `ui-core.js` as the first strict TypeScript entry.
+
+**Exit criterion:** shared UI behavior is TypeScript, tested, and does not add
+new globals.
+
+### Phase 4: Independent Leaf Modules
+
+Convert lower-coupling code first:
+
+1. WebGL renderer;
+2. decode-history worker;
+3. screenshot support;
+4. FT2 and FT4;
+5. WSPR;
+6. CW and other decoder views.
+
+Workers must be separate build entries.
+
+**Exit criterion:** each converted module has typed inputs, outputs, and tests.
+
+### Phase 5: Plugin Loading
+
+- Move the inline loader out of `index.html`.
+- Replace classic-script injection with typed dynamic imports.
+- Register plugins through `TrxPlugin`.
+- Preserve lazy loading by tab and feature.
+- Remove the corresponding global callbacks after each plugin migrates.
+
+**Exit criterion:** plugin dependencies and loading order are represented by the
+module graph rather than implicit script order.
+
+### Phase 6: Split the Main Application
+
+Extract `app.js` by responsibility:
+
+1. authentication and API transport;
+2. rig enumeration and switching;
+3. radio commands and capabilities;
+4. audio streaming;
+5. spectrum state and rendering;
+6. decode history;
+7. recorder;
+8. keyboard shortcuts;
+9. application bootstrap.
+
+Do not split by arbitrary line ranges. Each extraction must establish an
+explicit interface and remove the corresponding globals.
+
+**Exit criterion:** the bootstrap file composes services and features but does
+not contain their implementations.
+
+### Phase 7: High-Coupling Features
+
+Convert the remaining large features after the core contracts are stable:
+
+- scheduler and satellite scheduler;
+- bookmarks;
+- virtual channels;
+- map and map-backed statistics;
+- remaining decoder plugins.
+
+**Exit criterion:** no first-party classic scripts or untyped plugin callbacks
+remain.
+
+### Phase 8: Asset-Server Consolidation
+
+- Enable code splitting and hashed chunks.
+- Embed the generated asset directory in Rust.
+- Serve generated assets through a generic, allowlisted handler.
+- Add appropriate immutable caching for hashed output.
+- Retain stable handling for HTML and version metadata.
+- Remove obsolete fixed-asset constants and handlers.
+
+**Exit criterion:** Rust no longer needs a source edit for every generated
+frontend chunk.
+
+### Phase 9: Strictness and Cleanup
+
+- Remove `allowJs`.
+- Remove the legacy global bridge.
+- Enable all selected strict compiler and lint rules.
+- Remove obsolete generated compatibility bundles.
+- Update architecture and contributor documentation.
+
+**Exit criterion:** all first-party frontend source is strict TypeScript and the
+browser runtime exposes only intentionally documented globals.
+
+## 11. Testing Strategy
+
+Frontend CI should run:
+
+```sh
+npm ci
+npm run typecheck
+npm run lint
+npm test
+npm run build
+git diff --exit-code -- assets/web/generated frontend/src/api/generated.ts
+```
+
+Testing should cover four layers:
+
+1. **Pure unit tests** for bandwidth calculations, formatting, state changes,
+   capability decisions, and message routing.
+2. **DOM component tests** for dialogs, tabs, workspace selection, rig
+   switching, and collapsible control sections.
+3. **Worker tests** for decode-history pruning, batching, and message formats.
+4. **Browser smoke tests** for startup, authentication gating, plugin loading,
+   navigation, rig switching, audio controls, and map initialization.
+
+The existing dependency-free `ui-core` test can remain during the scaffold
+phase. It should be moved to the standard TypeScript test runner once that
+runner is established.
+
+## 12. CI Changes
+
+Add a dedicated frontend job rather than hiding frontend work inside the Cargo
+jobs. The job should:
+
+- use the Node.js version provided by the runner image;
+- run with `npm ci`, never a mutable install;
+- cache the npm download cache, not `node_modules`;
+- type-check, lint, test, and build;
+- verify generated artifacts and Rust-generated types are current;
+- run REUSE validation after generated files are produced.
+
+Rust lint and test jobs should continue to consume committed generated assets.
+
+## 13. Pull Request Strategy
+
+Use small, independently reversible pull requests. A recommended sequence is:
+
+1. tooling and unchanged JavaScript build;
+2. generated Rust wire types and typed API client;
+3. `ui-core` conversion;
+4. worker and WebGL conversion;
+5. decoder plugin conversions in small groups;
+6. plugin registry and dynamic imports;
+7. one `app.js` responsibility per PR;
+8. scheduler, bookmarks, and map conversions;
+9. generic embedded asset serving;
+10. removal of JavaScript compatibility mode.
+
+Every PR should include:
+
+- runtime behavior preserved or intentionally documented;
+- frontend type checking and tests;
+- strict Rust formatting and Clippy;
+- generated-artifact drift verification;
+- no newly introduced undocumented `window` globals;
+- no remote runtime asset dependency.
+
+## 14. Risks and Mitigations
+
+### Superficial Conversion
+
+**Risk:** globals receive declarations but remain coupled and mutable.
+
+**Mitigation:** require every converted module to expose explicit inputs and
+outputs and remove at least the globals it replaces.
+
+### Cargo Becomes Dependent on Node
+
+**Risk:** builds fail on systems without Node or network access.
+
+**Mitigation:** commit deterministic generated output and keep npm outside
+`build.rs`.
+
+### Script-Order Regressions
+
+**Risk:** switching to modules changes execution timing and scope.
+
+**Mitigation:** retain current public entries initially, then replace script
+loading only after the plugin registry is in place.
+
+### Unreviewable `app.js` Rewrite
+
+**Risk:** a large conversion is difficult to review, test, or bisect.
+
+**Mitigation:** extract one responsibility at a time and keep bootstrap working
+after every extraction.
+
+### Rust and Browser Contracts Drift
+
+**Risk:** TypeScript compiles against stale wire definitions.
+
+**Mitigation:** generate types from Rust and enforce a clean working tree after
+generation in CI.
+
+### Generated Asset Noise
+
+**Risk:** committed bundles make reviews noisy.
+
+**Mitigation:** separate source and generated commits when useful, include
+source maps, and require deterministic output.
+
+### Bundle or Startup Regression
+
+**Risk:** bundling loads too much code eagerly.
+
+**Mitigation:** record the current baseline, preserve feature-level lazy loads,
+and track entry/chunk sizes in CI.
+
+## 15. Initial Proof of Concept
+
+The first implementation PR should be deliberately limited to:
+
+1. adding the frontend package and locked toolchain;
+2. building existing JavaScript to fixed-name generated output;
+3. adding frontend CI and drift checks;
+4. generating initial rig/status TypeScript definitions;
+5. introducing the typed API client;
+6. converting `ui-core.js` to strict TypeScript;
+7. preserving every existing asset URL and observable behavior.
+
+This proof of concept is the decision gate for the remainder of the migration.
+If it materially improves contract safety without making Cargo development
+unwieldy, continue with the phased plan. If it does not, the repository can
+retain the tooling and the converted core without committing to a full rewrite.
+
+## 16. Completion Criteria
+
+The migration is complete when:
+
+- all first-party browser source is strict TypeScript;
+- vendor files remain isolated and declared through narrow type adapters;
+- Rust wire types generate their browser contracts;
+- no feature depends on accidental script ordering;
+- no undocumented mutable `window` callbacks remain;
+- `app.js` has been replaced by a small typed bootstrap and feature modules;
+- frontend type checking, linting, unit tests, component tests, browser smoke
+  tests, and generated-output checks run in CI;
+- Cargo builds remain possible without Node.js or network access;
+- production assets remain local, embedded, cacheable, and reproducible.

+//! SSTV carries every pixel as a frequency between 1500 and 2300 Hz, and every
+//! line boundary as a 1200 Hz pulse, so one measurement serves the whole
+//! decoder: the frequency of the signal at each sample. A Hilbert transform
+//! FIR forms the analytic signal and the phase difference between consecutive
+//! samples gives the frequency.
+//!
+//! The same approach drives the WEFAX decoder, which maps the result straight
+//! to luminance. Here the frequency itself is the output, because the VIS
+//! header and the sync detector read tones far outside the pixel band.
+//!
+//! Block-based linear processing, per `docs/Optimization-Guidelines.md`: the

+# Frontend source
+
+This directory contains the strict TypeScript source for the browser assets
+embedded by `trx-frontend-http`. `bootstrap.ts` is the production entry point;
+esbuild follows its imports and emits `/app.js`. Feature plugins are ESM entry
+points loaded on demand by `plugin-loader.ts`, and the decode-history worker is
+built with its own Web Worker TypeScript configuration.
+
+Run all frontend commands from the parent `frontend` directory:
+
+```sh
+npm ci
+npm run typecheck
+npm run lint
+npm test
+npm run test:browser
+npm run build
+npm run verify-generated
+```
+
+`npm run verify-generated` regenerates Rust wire contracts and browser bundles,
+then rejects drift from the committed files. The browser smoke test needs a
+local Chromium-family executable; set `PLAYWRIGHT_CHROMIUM_EXECUTABLE_PATH`
+when it is not installed at `/usr/bin/chromium`.
+
+Cargo consumes committed output under `../assets/web/generated`. It never
+invokes Node.js, installs packages, or accesses the network. After changing a
+source file, commit the deterministic generated asset changes together with the
+source change.
+
+## Boundaries
+
+- `api/generated.ts` is generated from Rust and must not be edited manually.
+- `api/client.ts` owns runtime validation at version-sensitive HTTP and SSE
+  boundaries.
+- `core/` contains dependency-light shared helpers.
+- `features/` contains application behavior grouped by responsibility.
+- `plugins/` contains lazy decoder and high-coupling feature entries.
+- `plugins/host.ts` declares the typed `window.trx` state and services that
+  feature bundles read; feature entries import it rather than reaching for bare
+  `window` properties, which the module graph does not publish.
+- Files under `assets/web/vendor/` are vendored JavaScript and are not part of
+  the TypeScript migration.
+
+First-party features communicate through imports, the typed plugin runtime, or
+the documented `window.trx` host interface. New standalone `window` callbacks
+are not permitted.
