No gossamer Zig/Idris2 core is vendored + +Sub-issue #109 describes hosting the UI "via the JNI bridge (per gossamer +`src/interface/abi/Types.idr`)". This PR does **not** link gossamer's Zig +FFI layer (`webview_android.zig`) or its Idris2 ABI into neurophone. Doing so +would mean vendoring gossamer's build (Zig + Idris2 toolchains, its own +`libgossamer.so`) as a neurophone build dependency, which is unbuildable in +this environment (no such toolchain wired into neurophone's `Cargo.toml` +workspace, no NDK to link an Android `.so` at all) and is out of scope for +this migration on its own. + +Instead, `NeurophoneActivity`/`NeurophoneBridge` reuse gossamer's *proven +Java-side pattern* directly: `hyperpolymath/gossamer +android/src/main/java/io/gossamer/GossamerActivity.java` (full-screen +`WebView`, hardened `WebSettings`, one JS-interface object, careful +`onDestroy`) and `GossamerBridge.java` (one `@JavascriptInterface` class +added via `addJavascriptInterface`) — verified by reading both files +directly. `android.webkit.WebView` is used from Java without any native +Zig layer in between, which is, in fact, exactly what gossamer's own +`webview_android.zig` itself ultimately calls into via JNI — so this cuts a +native-code layer we cannot build here, rather than skipping something +gossamer would otherwise provide. + +=== 2. Synchronous bridge, not gossamer's async IPC + +gossamer's real injected bridge (`hyperpolymath/gossamer +src/interface/ffi/src/main.zig`, lines ~2013-2091) is +`window.gossamer`/`window.__gossamer_invoke(name, payload) => Promise`, +routed through a Zig-side command-dispatch/bindings map, resolved later via +`evaluateJavascript`. Since this migration doesn't vendor that dispatcher, +`NeurophoneBridge` instead exposes each `NativeLib` call as a directly +callable, synchronous `@JavascriptInterface` method — a legitimate, simpler +Android idiom (`addJavascriptInterface` calls block the JS thread and return +values synchronously) that fits neurophone's actual situation: every +`NativeLib` call is already a fast in-process JNI call with no +cross-process queue to wait on. `dist/ui.mjs` reflects this directly (no +`Promise`/`await` plumbing around the bridge calls). + +A further, more fundamental correction only discoverable with a working +compiler in hand: `a3487cc`'s `bridge.affine` modelled the bridge as a +*typed extern object* (`extern let host: { invoke: (...) -> ... }`). The +real `affinescript` compiler's deno-esm backend cannot express that at all +— its `extern fn` lowering (`lib/codegen_deno.ml`) only supports a +compiler-maintained intrinsic table or a bare same-named global function +call, never an arbitrary `obj.method(args)`. Combined with this compiler's +stdlib documenting that it has no typed DOM binding yet either +(`stdlib/Canvas.affine`: blocked on `affinescript-dom`, issue #255), the +bridge/DOM layer is not expressible in AffineScript today at all — so this +PR draws the line differently from `a3487cc`: `src/logic.affine` holds only +the pure decision logic (genuinely compiled + tested, see +`assets/gossamer-ui/README.adoc` "AffineScript verification"), and +`dist/ui.mjs` is a hand-written harness around it, mirroring the upstream +compiler's own `tests/codegen-deno/*.harness.mjs` test convention rather +than inventing a new pattern. + +This is also, concretely, why neurophone's *own* prior AffineScript UI +attempt (`a3487cc`) had to be corrected rather than reused verbatim: it +assumed the gossamer async contract above and an extern shape the compiler +doesn't support, neither of which could have been checked at the time (no +compiler on hand). See `assets/gossamer-ui/README.adoc` "What changed vs +a3487cc" for the `SystemConfig` shape correction too. + +=== 3. RFC Q6 ("contribute upstream to gossamer") was never executed — verified, and superseded here + +`docs/migrations/RFC-ANDROID-KOTLIN-TO-RUST.adoc` Q6 resolved (2026-06-02) +to build a `gossamer-android-services` companion module upstream in +`hyperpolymath/gossamer` with four shim base classes (`Service` / +`BroadcastReceiver` / `AppWidgetProvider` / `Activity`), with neurophone's +shims becoming thin subclasses of those. + +Re-checked directly against `hyperpolymath/gossamer` this session: that +companion module does not exist. gossamer's Android surface is exactly +`GossamerActivity` + `GossamerBridge`, nothing else. Q6 was resolved but +never implemented. + +Rather than block this migration on filing and landing a new upstream +gossamer PR (out of scope for a neurophone-only change), this PR reverts to +the RFC's originally-proposed **Path (A)**: hand-written Java shims under +`android/` extending Android framework classes (`Service`, +`BroadcastReceiver`, `AppWidgetProvider`, `Activity`) directly. If a genuine +gossamer companion module lands upstream later, these shims are small enough +to re-point as a follow-up. + +=== 4. Directory layout: `android/app/src/main/java/...`, not the RFC's flat `android/src/main/java/...` + +The RFC's component table (and Q6) describe shims living at +`android/src/main/java/ai/neurophone/` — matching gossamer's own flat layout +(`android/src/main/java/io/gossamer/`). This PR uses +`android/app/src/main/java/ai/neurophone/` instead (the `app/`-module shape +the *legacy* Kotlin tree used), for two independently-verified reasons: + +. **The live estate CI carve-out requires it.** The Java/Kotlin ban's + exemption in `hyperpolymath/standards` + `.github/workflows/governance-reusable.yml` (RFC Q1, `standards#341`, + landed 2026-06-02) is the shell regex + `git ls-files '*.java' '*.kt' '*.kts' '*.groovy' | grep -vE '(^|/)android/.*/src/.*\.java$'`. + Tested directly: `android/app/src/main/java/ai/neurophone/NativeLib.java` + matches this pattern (exempt); the RFC's own proposed flat + `android/src/main/java/ai/neurophone/NativeLib.java` does **not** — there + is no `/src/` substring left over once `android/` is consumed, because + there's no intervening path segment. This is a real, verifiable + discrepancy between the RFC's own proposed layout and the CI rule the RFC + itself caused to be written; worth a maintainer's eyes even though it + doesn't block this PR (this PR uses the layout that actually satisfies the + rule). +. **Existing, already-committed tooling assumes it.** `scripts/build-android.sh` + (untouched by this PR) already hard-codes + `ANDROID_APP="$PROJECT_ROOT/android/app"` and copies built `.so` files to + `$ANDROID_APP/src/main/jniLibs//`; `scripts/install-on-phone.sh` + (also untouched) invokes `(cd android && ./gradlew :app:assembleRelease)`. + Both predate this PR and both assume the `android/app/` shape, not the + RFC's flat one. + +=== 5. No Gradle build was added + +The RFC (Q4) resolved to keep Gradle, just switch DSL flavour +(Kotlin `*.gradle.kts` → Groovy `*.gradle`), reasoning that "Gossamer's +existing `android/` directory uses raw Gradle". Re-checked directly: it does +not — `hyperpolymath/gossamer android/` contains exactly two Java files and a +README, no Gradle files at all. That premise was wrong. +`scripts/install-on-phone.sh` still assumes a Gradle wrapper +(`./gradlew :app:assembleRelease`) that has never existed in this repo's +`android/` tree in the form this PR restores it (the legacy Kotlin tree's own +`*.gradle.kts` files are gone from history's most recent state too). Adding +speculative Gradle build files with no way to invoke or verify them here (no +Gradle/NDK/Android-SDK in this environment) would be unverifiable ceremony, +so none were added. Building an installable APK remains an explicit follow-up +gated on real Android tooling, not something this PR claims to have solved. + +== Hygiene: stale `.hypatia-baseline.json` / `.hypatia-ignore` entries + +Both files carried entries for the legacy Kotlin/Gradle paths (tracking +issue #97), which no longer exist. This PR updates both to reference the new +Java shim paths added here and to point at this PR's issues instead, rather +than leaving dead references sitting next to newly-added live ones. See the +PR description for the exact diff. + +== What would still be needed for a real, installable build + +* An Android SDK + NDK (`cargo-ndk` or equivalent) to cross-compile + `crates/neurophone-android` and produce `libneurophone_android.so` for + `arm64-v8a`/`armeabi-v7a`/`x86_64` — `scripts/build-android.sh` already + handles this gracefully when absent (falls back to a host-only build), but + actually producing the `.so` needs the toolchain. +* Either a Gradle module (`android/build.gradle`, `android/settings.gradle`, + `android/app/build.gradle`, matching RFC Q4's Groovy-DSL decision) or some + other non-Gradle native Android packaging path, wired to + `scripts/install-on-phone.sh`'s existing `./gradlew :app:assembleRelease` + expectation (or a replacement of that expectation). +* The `affinescript` compiler vendored somewhere reachable by CI (it was + found on `PATH` in this authoring environment and genuinely used — see + `assets/gossamer-ui/README.adoc` "AffineScript verification" — but nothing + in CI currently re-runs `bash build.sh` / `deno task test:ui` to catch + drift between `src/logic.affine` and the committed `dist/logic.deno.js`). +* `affinescript-dom` (or equivalent) landing upstream, so the DOM/bridge + wiring currently hand-written in `dist/ui.mjs` could move into typed + AffineScript too — out of neurophone's control, tracked upstream in + `hyperpolymath/affinescript` issue #255. +* Device/emulator verification of the full lifecycle (service start/stop, + boot-restart, widget render/toggle, webview query round-trip) — none of + which could be exercised in this authoring environment. + +None of the above blocks this PR from being reviewed as a real, honest step: +the JNI ABI it calls into is genuinely merged and tested; `src/logic.affine` +is genuinely type-checked, compiled, and behaviourally tested; the +Java/hand-written-JS it adds is genuinely new source reviewed for +platform-API correctness, just not yet run in a real WebView or on a +device. diff --git a/android/app/src/main/AndroidManifest.xml b/android/app/src/main/AndroidManifest.xml new file mode 100644 index 0000000..4f7abd4 --- /dev/null +++ b/android/app/src/main/AndroidManifest.xml @@ -0,0 +1,100 @@ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + diff --git a/android/app/src/main/assets/gossamer-ui/README.adoc b/android/app/src/main/assets/gossamer-ui/README.adoc new file mode 100644 index 0000000..735bc1b --- /dev/null +++ b/android/app/src/main/assets/gossamer-ui/README.adoc @@ -0,0 +1,147 @@ +// SPDX-License-Identifier: CC-BY-SA-4.0 +// SPDX-FileCopyrightText: 2026 Jonathan D.A.
