chore(release): bump build number to 464 for the v4.5.7 rebuild

Version name stays 4.5.7 so the release is overwritten in place; the build
number must increase for Android to accept the update. This rebuild carries
the upstream rt-bishop merge (18 commits) on top of the 30 audit fixes.

 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
 
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
 
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under

+        * BARU: Decoder CW kini memakai jaringan saraf DeepCW — jauh lebih baik menafsir Morse sinyal lemah
+        * BARU: menyertakan model fp32 penuh untuk akurasi tertinggi
+        * BARU: Riwayat CW tersimpan permanen (teks tidak lagi hilang)
+        * Waterfall CW: skema warna inferno baru dengan gradasi halus
+        * Menu Lainnya: panel ramping di kanan, tanpa lapisan gelap
+        * Halaman CW: tombol kembali yang tidak berfungsi dan baris status yang menyesatkan dihapus
+        * Dukungan 64-bit (arm64) dipulihkan
+        * Perbaikan: jeda/lanjut tidak lagi menampilkan galat "gagal menafsir" yang keliru
+        * Perbaikan: memindahkan halaman ke menu utama tidak lagi menyembunyikan Pengaturan secara permanen
+        * Perbaikan: AMSAT/WavelogLog kini dapat dipindahkan ke menu utama
+        * Perbaikan: penguraian epoch satelit untuk waktu dalam 86 detik pertama tengah malam UTC
+        * Perbaikan: halaman radar kini otomatis beralih ke pass berikutnya setelah pass saat ini berakhir
+        * Perbaikan: perhitungan Doppler radar kini menggunakan nilai slider offset langsung
+        * Perbaikan: perhitungan kemajuan pass dijaga terhadap pembagian dengan nol
+        * Perbaikan: panggilan calculatePasses bersamaan tidak lagi memicu perhitungan duplikat
+        * Perbaikan: pengiriman QSO duplikat WaveLog dan kondisi balapan pembaruan grid square

+        * BARU: Decoder CW kini memakai jaringan saraf DeepCW — jauh lebih baik menafsir Morse sinyal lemah
+        * BARU: menyertakan model fp32 penuh untuk akurasi tertinggi
+        * BARU: Riwayat CW tersimpan permanen (teks tidak lagi hilang)
+        * Waterfall CW: skema warna inferno baru dengan gradasi halus
+        * Menu Lainnya: panel ramping di kanan, tanpa lapisan gelap
+        * Halaman CW: tombol kembali yang tidak berfungsi dan baris status yang menyesatkan dihapus
+        * Dukungan 64-bit (arm64) dipulihkan
+        * Perbaikan: jeda/lanjut tidak lagi menampilkan galat "gagal menafsir" yang keliru
+        * Perbaikan: memindahkan halaman ke menu utama tidak lagi menyembunyikan Pengaturan secara permanen
+        * Perbaikan: AMSAT/WavelogLog kini dapat dipindahkan ke menu utama
+        * Perbaikan: penguraian epoch satelit untuk waktu dalam 86 detik pertama tengah malam UTC
+        * Perbaikan: halaman radar kini otomatis beralih ke pass berikutnya setelah pass saat ini berakhir
+        * Perbaikan: perhitungan Doppler radar kini menggunakan nilai slider offset langsung
+        * Perbaikan: perhitungan kemajuan pass dijaga terhadap pembagian dengan nol
+        * Perbaikan: panggilan calculatePasses bersamaan tidak lagi memicu perhitungan duplikat
+        * Perbaikan: pengiriman QSO duplikat WaveLog dan kondisi balapan pembaruan grid square

+# DeepCW Decoder — module documentation
+
+The `feature:cw` module decodes Morse code (CW) with the DeepCW neural model
+instead of a classical DSP detector. This document records the architecture,
+the model provenance, the pitfalls we hit on real devices, and the verification
+results. It exists so the next person does not have to re-derive any of it.
+
+## Architecture
+
+```
+microphone (44.1 kHz PCM float)
+        │  AudioCapture.audioFlow()  → ~100 ms chunks
+        ▼
+CwDecodeScreen (feature:cw, pure Compose)
+        │  decoder.processBuffer(chunk)      waterfall.pushSamples(chunk)
+        ▼                                    ▼
+CwDeepDecoder (core:data)             CwWaterfallState (feature:cw)
+   resample → 3200 Hz                    resample → 3200 Hz
+   CwDeepBuffer (20 s rolling)           CwDeepSpectrogram.compute
+   CwDeepSpectrogram.compute             → rolling spectrogram history
+   ONNX Runtime session.run             → Canvas waterfall
+   CwCtcDecoder.greedy                  (400–1200 Hz band, same magnitudes
+   → decodedText StateFlow               the model sees)
+```
+
+**Why the split.** `core:domain` must stay pure Kotlin/JVM (KMP migration
+headroom, per `AGENTS.md`), so the ONNX Runtime dependency — which ships native
+libraries — lives in `core:data` behind the `ICwDecoder` interface. The
+spectrogram front-end (`CwDeepSpectrogram`) and CTC collapse (`CwCtcDecoder`)
+are pure Kotlin and live in `core:domain`, where they are unit-tested against
+the Python reference with golden vectors.
+
+**Streaming model, not incremental.** DeepCW is a whole-utterance CTC model. It
+rewrites earlier characters as more context arrives, so incremental appending is
+wrong. The decoder keeps a rolling buffer capped at 20 s and re-runs the whole
+window every 1.5 s, replacing the displayed text outright. 20 s is the smallest
+window that hits 0 % CER on the reference clip *and* the largest that keeps
+inference comfortably faster than real time (measured ~14× headroom on a server
+CPU; timed per-window on device and reported via `lastInferenceMs`).
+
+## Model
+
+| | Value |
+|---|---|
+| File | `assets/deepcw/model.onnx` (fp32, as published upstream) |
+| Size | 15,139,839 bytes |
+| Modifications | none — vendored byte-for-byte |
+| Input | `spectrogram` [1,1,T,65] float32 |
+| Output | `log_probs` [1,T,42] float32 |
+
+The full fp32 model ships inside the APK for maximum decode fidelity. An int8
+`quantize_dynamic` build was trialled earlier (~4× smaller, measurably identical
+at SNR ≥ −4 dB) but the shipped artifact is now the unmodified fp32 model. See
+[`licenses/NOTICE.md`](licenses/NOTICE.md) for provenance, commit SHA and hash.
+
+Audio must be packaged **uncompressed** (`noCompress += "onnx"` in the app
+module): ONNX Runtime mmap's assets and refuses compressed ones.
+
+## Pitfalls fixed on real devices (release-only)
+
+1. **R8 minification breaks the JNI binding.** `isMinifyEnabled = true` in the
+   convention plugin, but `onnxruntime-android` ships **no** consumer ProGuard
+   rules, so `ai.onnxruntime.*` got renamed and native code crashed with no Java
+   stack trace. Fixed with
+   `-keep class ai.onnxruntime.** { *; }` in `app/proguard-rules.pro`.
+   Symptom was the exact "flash to home screen, empty crash log" we chased.
+2. **Model load in `init{}`** took down the whole composable on failure; moved
+   to lazy `ensureLoaded()` with an `errorMessage` path.
+3. **Default thread count** saturated all cores and starved audio capture/UI;
+   capped `setIntraOpNumThreads` to `cores−1` (max 4).
+4. **Compose snapshot state written from the audio thread** crashes at runtime
+   with no log from business-class instrumentation; the waterfall now uses a
+   `MutableStateFlow` revision counter, and both the row deque and the pending
+   buffer are lock-guarded.
+5. **`LaunchedEffect { launch { collect() } }`** leaked a second `AudioRecord`
+   when toggling; collection now runs directly in the effect body keyed on
+   `(isListening, permissionGranted)`.
+
+Diagnostics (no-adb): `MainApplication` already writes uncaught exceptions to
+`files/crash_log.txt`. The decoder additionally persists load/inference failures
+to `files/deepcw_load_error.txt` / `files/deepcw_infer_error.txt` and step
+markers to `files/probe_cw.txt` (`load_begin → load_session_ok → infer_begin →
+infer_done`).
+
+## Verification
+
+- **Golden vectors**: `CwDeepSpectrogramTest` + `CwDeepGoldenVectorTest` pin the
+  Kotlin spectrogram to the Python reference across 5005 values (tolerance
+  1e-4). 79 domain tests pass.
+- **End-to-end on server**: real 20 s noisy CW audio → resample → spectrogram →
+  ONNX → greedy CTC reproduces `CQ CQ DE BG7NTA BG7NTA K 5NN TU 73`
+  character-for-character (~1 s inference, fp32).
+- **On device (release APK)**: decodes 40 WPM CW at high accuracy. Some UI
+  latency is expected on the first decode cycle (model load + first inference);
+  sustained decoding stays real-time.
