…utions + all 5 frontends)
Establishes the complete v2 skeleton per MASTER_PLAN.md — every integration
point between the C++ core, engine plugins, L5 solutions, and the 5 language
frontends is defined with a passing CMake build + 36 unit tests.
## What's included
* `idl/*.proto` — proto3 IDL (voice_events, pipeline, solutions)
* `core/abi/` — stable extern "C" ABI (ra_primitives, ra_pipeline, ra_plugin,
ra_version). Every frontend binds against this.
* `core/graph/` — L4 primitives: RingBuffer, MemoryPool, StreamEdge,
CancelToken, PipelineNode, GraphScheduler
* `core/registry/` — PluginRegistry + PluginLoader<VTABLE> (dual-path:
static iOS/WASM, dlopen Android/macOS/Linux)
* `core/router/` — EngineRouter + HardwareProfile
* `core/voice_pipeline/` — concrete mic→VAD→STT→LLM→TTS VoiceAgent with
transactional barge-in cancel boundary (ports RCLI orchestrator.h:215-218)
* `core/model_registry/` — model metadata + downloader
* `engines/{llamacpp,sherpa,wakeword}/` — L2 engine plugin skeletons with
real vtable wiring; stub impls return RA_ERR_RUNTIME_UNAVAILABLE (real
integrations land per-engine in follow-up PRs)
* `solutions/voice-agent/` — ergonomic builder on top of voice_pipeline
* `solutions/rag/` — BM25Index + HybridRetriever (parallel BM25+vector+RRF)
ported from FastVoice RAG/temp/src/rag/
* `frontends/swift/` — SwiftPM package, RunAnywhere + VoiceSession +
AudioSession + RegistrationBuilder + XCTest
* `frontends/kotlin/` — Gradle module with Wire proto3 codegen + Flow<VoiceEvent>
* `frontends/dart/` — pub package with FFI scaffolding
* `frontends/ts/` — npm package with JSI TurboModule scaffolding
* `frontends/web/` — npm + Emscripten WASM build with asyncify
* `idl/codegen/generate_{swift,kotlin,dart,ts,python}.sh` — regeneration
scripts; CI verifies no drift
* `tools/benchmark/` — per-primitive ra_bench latency harness
* `tools/pipeline-validator/` — static DAG validation stub
* `CMakeLists.txt` + `CMakePresets.json` — root build (macos-debug,
macos-release, macos-tsan, linux-*, ios-release, android-release,
wasm-release)
* `cmake/{platform,sanitizers,plugins,protobuf}.cmake` — helpers
* `vcpkg.json` — dependency manifest
* `.github/workflows/v2-core.yml` — CI: C++ core + Swift + Kotlin + Dart
+ TS/Web frontends all build and test on every PR
* `.clangd` — C++20 hints for IDEs before first CMake configure
* `docs/v2-migration.md` — v1↔v2 coexistence strategy
* `core/README.md` — build + extension guide
* `core/tests/` — 36 gtest unit tests covering RingBuffer, MemoryPool,
CancelToken, StreamEdge, SentenceDetector, TextSanitizer, PluginRegistry,
EngineRouter. All 36 pass with ASan + UBSan on macOS arm64.
## IMM fixes included
* IMM-2: `sdk/runanywhere-kotlin/scripts/build-kotlin.sh` — replace
macOS-only `stat -f %m` with cross-platform `_ra_stat` wrapper so Linux
CI no longer silently rebuilds commons on every run.
## Coexistence with v1
v2 is entirely additive — no v1 file is modified except the build-kotlin.sh
bug fix above. The legacy `sdk/runanywhere-*` trees continue to ship
unchanged. Clients migrate one SDK at a time as each L6 frontend lands
a full JNI/JSI/FFI bridge in subsequent PRs.
## Verification
* `cmake --preset macos-debug && cmake --build --preset macos-debug`
succeeds on macOS 15 / Apple Silicon
* `ctest --preset macos-debug` → 36/36 tests pass with ASan + UBSan

Fix the proto3 default mismatch for barge-in.
Line 46 documents default true, but an omitted proto3 bool decodes as false. This means clients that omit this field will disable barge-in by default, contradicting the intended behavior. The C++ struct has a workaround with an explicit initializer, but other language clients or direct proto consumers won't benefit from it. Invert the field or add explicit presence before generated APIs ship.
Proposed fix using an inverted flag
- bool enable_barge_in = 8; // default true
+ bool disable_barge_in = 8; // default false, so barge-in is enabled by default📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

…oto drift check * `.gitignore` was ignoring top-level `tools/` (a relic from node/python patterns). The v2 `tools/benchmark` and `tools/pipeline-validator` sources were therefore never uploaded, causing cmake configure to fail with "source is not an existing directory" on both Linux and macOS workers. Removed both `tools/` rules. * `frontends/dart/pubspec.yaml` used `flutter_test` which pulls the entire Flutter SDK. CI only installs the Dart SDK, so `dart pub get` failed with "runanywhere_v2 requires the Flutter SDK". Switched to pure `package:test` + `package:lints`; updated `analysis_options.yaml` to `lints/recommended.yaml`. * `proto-codegen-swift` drift check treated a freshly-initialized `Generated/.gitkeep`-only directory as stale. Added a gate: the drift check now only runs once at least one `*.pb.swift` file is tracked. First real codegen PR flips this on.
cpp-macos workers don't ship gtest by default, so find_package() returned not-found and core/tests/CMakeLists.txt silently returned. Then the CI `ctest` step still ran, got "no tests", and exited 8 (treated as failure). Switched to FetchContent(googletest v1.14.0) as a fallback when find_package fails. Now both CI paths (system gtest or fetched gtest) produce a working test binary.
…ortability Four correctness fixes surfaced by CodeRabbit on PR #485: 1. **ABI: stable boolean encoding** `bool` (C99 `_Bool`) has implementation-defined size, and padding around `bool` fields is platform-dependent. This breaks strict ABI compatibility across Swift `Bool`, JNI `jboolean` (unsigned 8-bit), Dart FFI `Uint8`, Emscripten, and MSVC. Switched every public boolean in `core/abi/ra_primitives.h` + `core/abi/ra_plugin.h` to `uint8_t` with 0=false / non-zero=true semantics, and documented the convention in the header. Explicit reserved[] slots now cover what used to be compiler-inserted padding. 2. **Static plugin linkage: unique symbol per engine** Every engine plugin used to export `extern "C" ra_plugin_entry`. On dlopen platforms that's fine — each plugin lives in its own .so/.dylib — but on iOS and WASM (RA_STATIC_PLUGINS=ON), all three plugins link into the same binary, producing a duplicate-symbol linker error. Introduced `RA_PLUGIN_ENTRY_DECL(PluginName)` in `core/abi/ra_plugin.h`: expands to `extern "C" ra_plugin_entry` on dlopen builds, and to file-local `static PluginName_fill_vtable` on static builds. Each engine (`llamacpp`, `sherpa`, `wakeword`) now declares its entry via the macro. `RA_STATIC_PLUGIN_REGISTER(PluginName)` no longer takes the function pointer as a second argument — it reuses the name generated by `RA_PLUGIN_ENTRY_DECL`. Auto-register type is renamed to `PluginName##_auto_register_t` to avoid clashing with the instance. 3. **GraphScheduler partial-initialization leak** If `node[k]->initialize()` threw, nodes `0..k-1` had been successfully initialized but never had a worker launched — so their `finalize()` contract was never invoked, leaking engine sessions, file handles, and threads. `start()` now tracks `initialized_prefix` and, on failure, iterates back through the already-initialized prefix calling `finalize()` in reverse order before signalling completion. 4. **build-kotlin.sh: broader C/C++ file extensions** The rebuild detector only watched `*.cpp` / `*.h`, so edits to `.cc`, `.cxx`, `.c`, `.hpp`, `.hh`, `.inl`, or `.mm` slipped past and left stale JNI libs. Widened the `find` expression to cover the full conventional set. Docs: `docs/v2-migration.md` now explicitly calls out the build-kotlin.sh v1 touch instead of claiming zero v1 changes. Verification: `cmake --build --preset macos-debug` succeeds, 36/36 unit tests pass locally with ASan + UBSan enabled.

- Around line 101-105: The current loop only sleeps and records synthetic
latencies; instead, call the real routed primitive (use result.plugin or the
engine's invoke/run method used elsewhere) inside the measured window (between
t0 and t1) so the latency reflects the actual operation, and push that measured
duration into latencies; if result.plugin (or the expected primitive) is not
available, make the benchmark fail fast with a clear error message indicating
measurement is not implemented rather than reporting sleep-based min/p50/p90/p99
values.
- Line 74: After parse_args returns (the const auto opts = parse_args(argc,
argv); line), validate opts.iterations is > 0 and reject otherwise (print a
clear error and exit/return non-zero) before allocating or recording latencies;
similarly, guard the latencies.reserve call so it only reserves when iterations
is positive to avoid huge/invalid sizes and prevent later dereferencing of
empty-range results (e.g., min/max/mean computations that use the latencies
vector). Locate checks around parse_args, uses of opts.iterations, and the
latencies.reserve and stats-collection code paths and add the validation early
to fail fast.
- Line 87: RouteRequest is currently constructed with a hard-coded
RA_FORMAT_GGUF which breaks routing for non-LLM primitives; change the
construction to select the format based on the chosen primitive (the local

logic before creating RouteRequest to map generate_text/embed -> RA_FORMAT_GGUF
and transcribe/synthesize/detect_voice/wake_word -> RA_FORMAT_ONNX (or accept
the CLI-provided format) and then pass that format into RouteRequest(prim,
selected_format, 0, opts.engine) so the correct backend is routed.

In `@tools/pipeline-validator/validator.cpp`:
- Around line 27-31: The current stub prints the received size and returns
success unconditionally (see printf("pipeline validator: %zu bytes received —

only return 0 if that flag is set); keep the diagnostic printf but ensure the
default path returns failure until runanywhere.v1.PipelineSpec decoding and DAG

Hard-coded GGUF format will fail for non-LLM primitives supported by the CLI.

Avoid reporting synthetic sleep as benchmark latency.
The tool prints production-looking min/p50/p90/p99 numbers, but the loop only sleeps for 100µs and never exercises result.plugin. Since the header says this feeds the Phase 0 latency gate, either invoke the routed primitive here or fail clearly until real measurement is implemented.

Don’t return success before validation exists.
Right now any non-empty bytes are reported as successful validation, which contradicts the documented exit semantics and can let invalid pipeline specs pass automation. Until PipelineSpec decoding and DAG checks are implemented, fail closed or gate this behind an explicit stub mode.

… resolves CodeRabbit flagged the install() step as incomplete: only `abi/*.h` was shipped, so downstream `find_package(RunAnywhere)` consumers that linked `RunAnywhere::core_graph` etc. would fail to locate any of the `graph/`, `registry/`, `router/`, `voice_pipeline/`, `model_registry/` public headers. Three fixes: 1. Every PUBLIC include directory on the component libraries now carries both `$<BUILD_INTERFACE:…>` (in-tree compile) and `$<INSTALL_INTERFACE:include>` (installed find_package tree), so the generated RunAnywhereTargets.cmake points to valid include paths regardless of which side the consumer is on. 2. install(DIRECTORY …) now ships every public sub-tree, not just abi/. All component headers land under `<prefix>/include/runanywhere/`. 3. The INTERFACE utility targets `ra_platform_flags` and `ra_sanitizers` are added to the export set via `install(TARGETS … EXPORT RunAnywhereTargets)`. Without this, CMake refused to export `ra_core_*` because their transitive link deps were unreachable via the install tree. Also added `install(EXPORT RunAnywhereTargets …)` with a `RunAnywhere::` namespace so the generated targets file is drop-in for any downstream `target_link_libraries(app PRIVATE RunAnywhere::core)`. Verification: `cmake --preset macos-debug && cmake --build --preset macos-debug` succeeds, 36/36 unit tests pass under ASan + UBSan.
1. **memory_pool.h — allocation failure path**
When `posix_memalign` / `_aligned_malloc` fails, `storage_` becomes
null but the free-list loop still pushed `nullptr + i*stride` entries.
Subsequent `acquire()` returned a poisoned pointer; the pool falsely
reported `available() == num_blocks`. Added:
- early-return when `alignment` is not a power of two >= sizeof(void*)
- explicit `if (!storage_) return;` after the allocation call, leaving
free_list_ empty so acquire() returns nullptr cleanly.
- `<cstdlib>` / `<malloc.h>` includes that we were relying on
transitively.
2. **plugin_loader.h — dlerror() double-call UB**
`dlerror()` both reports and clears the last error, so calling it twice
returned null the second time. Constructing `std::string` from null is
undefined behavior. Capture once, null-check, then assign.
3. **voice_pipeline — audio tee to VAD + STT**
`audio_edge_` was consumed by both `vad_loop` and `stt_loop`, and
`StreamEdge::pop()` removes items (single-consumer semantics). Frames
got split nondeterministically between the two workers, breaking both
barge-in detection and transcription. Split into `vad_audio_edge_` and
`stt_audio_edge_`; `feed_audio()` tees each incoming frame into both.
4. **BM25Index — drop mutable scratch, accept caller-owned buffer**
The `const` `search()` method wrote to a `mutable std::vector<float>
scratch_scores_`, which is a data race when multiple threads call
`search()` concurrently. The new signature takes an optional pointer to
a caller-owned scratch vector (thread-local hot paths pass a reused
buffer; callers that don't care pass nullptr and a local is allocated
per call). No shared mutable state; the class is now truly
multi-reader-safe after `build_done()`.
Verification: cmake --build + ctest → 36/36 pass with ASan + UBSan.
…ding Any capacity above the highest representable power of two wrapped round_up_pow2 to zero, producing a buffer with size_t-max mask that permanently looked full. Throw std::length_error at construction instead of allocating `new T[0]` and silently breaking. Does not affect any current call site (all edges cap at 256), just hardens against future misuse.
Two CodeRabbit nits: * benchmark main now rejects --iterations <= 0 up front instead of running stats over an empty latencies vector and dereferencing out-of-range min/max iterators. * v2-core.yml push filters now match the pull_request filters. Direct merges to main that touched only tools/, vcpkg.json, or the workflow itself would have silently skipped the CI.

Inline comments:
In `@cmake/platform.cmake`:
- Around line 91-106: The generator expressions used in target_compile_options
for target ra_platform_flags currently pass multi-word flag strings (e.g.
$<$<CONFIG:Debug>:-O0 -g>) which should be semicolon-separated per CMake best
practices; update each multi-flag expression for both branches (the MSVC
expressions around /Od and /Zi and the non-MSVC expressions around -O0 and -g)
to use semicolon-separated lists inside the generator expressions (e.g. replace
the space-separated flag lists in the $<$<CONFIG:Debug>:...> and
$<$<CONFIG:Release>:...> generator expressions with semicolon-separated items)
so CMake treats them as separate flags.
In `@core/abi/ra_plugin.h`:
- Around line 51-54: The public ABI field capability_check currently exposes C's
bool; change its type to uint8_t and document/use 0/1 semantics to keep the
plugin ABI fixed-width and consistent with other fields; update the declaration
of capability_check to use uint8_t (*capability_check)(void) and ensure any
callers/implementations convert boolean results to 0 or 1 accordingly.
In `@core/abi/ra_primitives.h`:
- Around line 197-199: The comment references a nonexistent sync API; either add
the missing ABI declaration for ra_llm_generate_sync or remove the sentence
pointing to it. Locate the asynchronous generator declaration around ra_status_t
ra_llm_generate(ra_llm_session_t* session, ...) and either (A) add a matching
prototype for ra_llm_generate_sync with the appropriate ra_status_t return and
ra_llm_session_t parameter(s) consistent with ABI conventions, or (B) delete or
reword the sentence that mentions ra_llm_generate_sync so the header only
documents the existing ra_llm_generate symbol.
- Around line 35-49: Add a distinct error code for caller buffer-too-small cases
and return it instead of RA_ERR_OUT_OF_MEMORY: add a new enum entry (e.g.
RA_ERR_INSUFFICIENT_BUFFER = -12) to the RA_* list, change the code path that
currently maps the recoverable out_pcm capacity issue to RA_ERR_OUT_OF_MEMORY so
it returns RA_ERR_INSUFFICIENT_BUFFER, and ensure that on that return path the
out parameter written_samples is set to the number of samples actually written
(or zero if none) so callers can decide to retry with a larger buffer; reference
symbols: RA_ERR_OUT_OF_MEMORY, add RA_ERR_INSUFFICIENT_BUFFER, out_pcm, and
written_samples.
In `@core/CMakeLists.txt`:
- Around line 15-18: The exported targets advertise <prefix>/include but headers
are installed under <prefix>/include/runanywhere (and some INSTALL_INTERFACE
entries use trailing slashes that flatten subdirs), so update the
target_include_directories declarations (e.g.,
target_include_directories(ra_core_abi PUBLIC ...)) to use INSTALL_INTERFACE
paths that match the actual installed layout (for example include/runanywhere
and preserve subdirectory names like graph, registry rather than using trailing
slashes), and apply the same change to the other targets mentioned (the blocks
around lines 31-34, 46-49, 62-65, 79-82, 96-99, 123-134) so exported consumers
get correct include paths.
In `@docs/v2-migration.md`:
- Around line 41-42: In docs/v2-migration.md replace the incorrect "Github"
capitalization with the official "GitHub" where it appears (for example in the
CI workflow line that references `.github/workflows/v2-core.yml` or any
occurrence of "Github"); update the string to "GitHub" so all mentions use the
correct casing.

- Around line 48-55: In ww_feed_audio, after validating the detected pointer
(keep the existing RA_ERR_INVALID_ARGUMENT check), do not silently set *detected
= 0 and return RA_OK; instead return RA_ERR_RUNTIME_UNAVAILABLE to indicate the

Refactor multi-flag generator expressions to use semicolon-separated lists.
While the current syntax ($<$<CONFIG:Debug>:-O0 -g>) compiles successfully because compilers accept space-separated flags in a single argument, it doesn't follow CMake best practices. Use semicolon-separated lists instead, which CMake explicitly handles as flag lists:

Keep the plugin ABI fixed-width here too.
bool is still exposed in the public C plugin ABI via capability_check. Since this ABI is consumed across languages/toolchains, use uint8_t with 0/1 semantics like the other fixed-width ABI fields.

Use a distinct status for insufficient caller buffers.

can race; fix by taking the same mutex that llm_loop() uses to publish
llm_session_ (use the existing llm-session mutex used around llm_session_ in
llm_loop()) before reading/cancelling llm_session_, and serialize ring-buffer

expected_abi_version silently discarded — the documented "ABI version handshake" isn't enforced.
The file-level comment (lines 6-9) states this loader is intended for plugins that "Has an ABI version handshake", and load() takes expected_abi_version, but line 96 casts it to void. Callers pass a version expecting rejection on mismatch; instead any ABI is accepted. Either resolve and compare the plugin's reported ABI version (e.g., via a well-known required symbol or a field populated into vtable_ such as ra_engine_vtable_t::abi_version) before setting loaded_ = true, or remove the parameter and doc claim to avoid a false sense of safety.

unload() leaves dangling pointers in vtable_.
dlclose() unmaps the library, but vtable_ is not reset. After unload():
vtable()still returns a reference whose function pointers now target unmapped memory — calling through them is UB.loaded() == falseis the only guard, and nothing in the public API prevents a caller from readingvtable()post-unload.- More subtly, on
load()→unload()→load()of a different library, any optional symbol that was resolved the first time but is absent the second time retains its stale pointer (line 85continueskips the write), pointing into the previous, now-closed library.
Reset vtable_ to {} in unload() (and clear last_error_ at the top of load() if desired).
🐛 Proposed fix
void unload() {

::dlclose(handle_);
handle_ = nullptr;
}
+ vtable_ = VTABLE{};
loaded_ = false;
}Apply the analogous reset in the static-mode unload() on line 113 if adopt() may be called more than once.

Clear barge_in_flag_ before waking the LLM worker.
transcript_edge_.push() can wake llm_loop() immediately; until Line 265 runs, the token callback still drops tokens as stale barge-in output. Move the flag clear before publishing the new final transcript.

Surface TTS backend failures instead of silently dropping speech.
When tts_synthesize() returns an error, the assistant response loses audio with no kError event. This is especially visible while native engines still return runtime-unavailable stubs.

Validate doc_id before treating it as a dense row index.
Lines 48-56 resize doc_lengths_ by doc_id + 1, while line 60 uses doc_lengths_.size() as BM25 corpus size. Sparse IDs create zero-padded vectors that corrupt IDF and average document length statistics. Duplicate IDs overwrite doc_lengths_ but leave stale postings intact. UINT32_MAX wraps modulo 2³² before resize, causing an out-of-bounds access at doc_lengths_[UINT32_MAX].
Add either:
- A precondition check enforcing dense, unique, zero-based IDs, or
- An internal-to-external ID mapping with a dense row index for statistics

CodeRabbit flagged that `find()`, `find_by_name()`, and `enumerate()` returned `const PluginHandle*` pointing into `std::vector<PluginHandle> plugins_`. `push_back` / `erase` inside `register_static`, `load_plugin`, and `unload_plugin` invalidate those pointers — a real use-after-free window, not theoretical, because `load_plugin` and `unload_plugin` can run concurrently with router lookups on Android / macOS / Linux. Fix: store `std::vector<std::shared_ptr<PluginHandle>>` and return `PluginHandleRef` (`std::shared_ptr<const PluginHandle>`) everywhere. Any outstanding handle ref keeps the PluginHandle memory alive even if the registry entry is erased, so worker threads that are mid-vtable-call during an `unload_plugin` complete safely. * `enumerate()` now snapshots the plugin list under the lock and invokes the callback outside the lock, so callbacks that recursively mutate the registry don't deadlock. * `unload_plugin()` takes the shared_ptr out of the vector, calls plugin_shutdown outside the lock, and then dlclose's the backing image. Outstanding callers keep their ref-counted handle valid for memory safety, though they must still have destroyed any sessions before calling unload_plugin (sessions sit on engine-internal state that doesn't live in PluginHandle). * `load_plugin` now captures `dlerror()` once before logging (avoids the UB double-call that was fixed in plugin_loader.h separately). RouteResult.plugin type changed from `const PluginHandle*` to `PluginHandleRef`; VoiceAgentPipeline's four engine-handle members changed similarly. All compile sites updated; test assertions use the shared_ptr's `operator bool` and `operator->`. Verification: cmake --build → clean, ctest → 36/36 pass under ASan+UBSan.
CodeRabbit flagged that StreamEdge registered `[this]() { wake_all(); }`
with CancelToken::on_cancel and never deregistered it. Since CancelToken
stores callbacks indefinitely and invokes them on cancel() — and a token
commonly outlives the individual edges that reference it in a real
pipeline — a cancel() after edge destruction would call `wake_all()` on
freed memory.
Fix: the edge owns an internal `std::shared_ptr<AliveFlag>` (a tiny
struct holding a mutex and a bool). The CancelToken callback captures
that shared_ptr by value. Under the shared mutex, the callback either
sees `live=true` and wakes the edge, or sees `live=false` and returns
without touching `this`.
~StreamEdge() takes the same mutex before setting `live=false`, so it
synchronizes with any in-flight callback — either the callback
completes before the destructor runs, or it observes the cleared flag.
Future firings of cancel() hit the same gate and are safe no-ops.
No API change. No allocation on the hot path (the AliveFlag is created
once per edge).
Tests: 36/36 pass under ASan + UBSan.
Four more CodeRabbit majors: 1. **solutions.proto** — `VoiceAgentConfig` referenced an `audio_file_path` in comments but had no corresponding field. Added `string audio_file_path = 15` — consumed when `audio_source == AUDIO_SOURCE_FILE`. 2. **voice_events.proto** — `MetricsEvent` was missing the `is_over_budget` flag that `pipeline.proto` documents. Added `bool is_over_budget = 7` so frontends can surface SLO violations without re-computing the threshold. 3. **pipeline.proto** — clarified that `EdgeConfig.capacity == 0` means "use the per-edge default" in the comment, since proto3 scalars have no explicit presence bit. 4. **frontends/ts/package.json** — added `"type": "module"` and `"exports"` map so Node treats the dist as ESM (matching the ESNext target in tsconfig). ESM consumers would otherwise hit CJS interop errors. 5. **frontends/web/wasm/CMakeLists.txt** — `ra_pipeline_create_from_solution`, the C ABI entrypoint frontends use to bootstrap solutions, was missing from the Emscripten `-sEXPORTED_FUNCTIONS` list. Emcc would dead-strip it and JS calls would fail at runtime. Added every public ABI symbol (pipeline lifecycle + set_event_callback + set_completion_callback + feed_audio + inject_event + validate + status_str + plugin_api_version + build_info). Switched from `set_target_properties(LINK_FLAGS)` to `target_link_options` with `SHELL:` form to avoid shell-quoting traps.
No worker files / worker APIs are used in the current web adapter; keeping the lib declaration pollutes the global types unnecessarily. Will be re-added when Phase 3 lands the WASM worker offload path.

Inline comments:
In `@core/graph/stream_edge.h`:
- Around line 59-64: The StreamEdge constructor(s) must reject a zero capacity
to prevent infinite blocking or deque underflow in push(); update the
StreamEdge(std::size_t capacity, std::shared_ptr<CancelToken> token = nullptr,
EdgePolicy policy = EdgePolicy::kBlock) (and the other overload around lines
96-106) to validate that capacity > 0 and throw a clear exception (e.g.,
std::invalid_argument) if capacity == 0, so invalid edges are rejected at
construction rather than allowing push() to enter the full-loop path.
In `@core/router/engine_router.h`:
- Around line 42-61: The header has a data race: refresh_hardware() mutates hw_
while const route() / score_plugin() read it, risking torn std::string reads;
fix by making hw_ thread-safe — either replace hw_ with an atomic
std::shared_ptr<const HardwareProfile> and have route() take a snapshot (load
the shared_ptr once and pass the const HardwareProfile& into score_plugin()), or
protect hw_ with a mutex / std::shared_mutex and lock for shared access in
route()/score_plugin() and exclusive access in refresh_hardware(); update
EngineRouter members and signatures accordingly (referencing refresh_hardware,
route, hw_, score_plugin, and HardwareProfile).
- Around line 27-32: The RouteRequest struct is missing safe default
initializers for primitive and format; change the declarations in struct
RouteRequest so that primitive is initialized to RA_PRIMITIVE_UNKNOWN and format
is initialized to RA_FORMAT_UNKNOWN (use RA_FORMAT_UNKNOWN rather than the
non-existent RA_MODEL_FORMAT_UNKNOWN) to avoid indeterminate values for
ra_primitive_t and ra_model_format_t.
In `@core/voice_pipeline/voice_pipeline.h`:
- Around line 75-84: The Kind field in the VoiceAgentEvent struct is left
uninitialized; set a safe default for VoiceAgentEvent::kind (e.g., initialize it
inline to a neutral enum value like Kind::UNKNOWN or Kind::NONE) so a
default-constructed event has a deterministic kind; update the declaration of
"Kind kind;" to "Kind kind = Kind::UNKNOWN;" (or add a default constructor that
assigns Kind::UNKNOWN) and ensure the chosen enum member exists in the Kind
enum.
In `@frontends/web/wasm/CMakeLists.txt`:
- Around line 28-35: The build currently exports C ABI functions
(ra_pipeline_set_event_callback, ra_pipeline_set_completion_callback,
ra_pipeline_feed_audio) but omits runtime helpers needed to register callbacks
and pass Float32 buffers; update the target_link_options
EXPORTED_RUNTIME_METHODS to include "addFunction" and "removeFunction" and add
"HEAPF32" to the exported memory views so the JS glue can register callbacks and
write/read Float32 audio buffers (adjust the string in the target_link_options
that contains EXPORTED_RUNTIME_METHODS to include these symbols alongside the
existing 'ccall','cwrap','HEAPU8', etc.).
- Around line 14-21: The STATIC plugin libraries (llamacpp_engine,
sherpa_engine, wakeword_engine, ra_solution_voice_agent, ra_solution_rag)
register themselves via static constructors but can be dropped by the linker;
update the CMake linking for target_link_libraries(runanywhere_v2_wasm ...) to
force-load these archives (use LINK_LIBRARY:WHOLE_ARCHIVE or wrap the libraries
with --whole-archive/--no-whole-archive when LINK_LIBRARY:WHOLE_ARCHIVE is
unavailable) so their static initializers run and ra_registry_register_static()
is not omitted at link time. Ensure the change applies only to those listed
targets and is guarded for CMake/toolchain compatibility.
In `@idl/pipeline.proto`:
- Around line 98-100: The proto field comment for bool strict_validation (in
idl/pipeline.proto) is misleading because the validator tool
(tools/pipeline-validator/validator.cpp) is a bootstrap stub that does not
decode PipelineSpec or perform validation; either implement actual DAG
validation in tools/pipeline-validator/validator.cpp (decode PipelineSpec, check
for cycles/disconnected edges and wire up errors when strict_validation is true)
or change the idl/pipeline.proto comment to state that strict_validation is a
placeholder/unused until the validator is implemented; reference the
strict_validation field and tools/pipeline-validator/validator.cpp and update
behavior/documentation accordingly.
- Around line 9-16: The proto files are still using v1 namespaces and
generated-language options (package runanywhere.v1, java_package
ai.runanywhere.proto.v1, java_outer_classname PipelineProto, objc_class_prefix
RAV1, swift_prefix RA) which collides with v1 SDKs; update the package to
runanywhere.v2 and adjust generated-language options accordingly (e.g.
java_package -> ai.runanywhere.proto.v2, java_outer_classname -> PipelineV2Proto
or similar v2-unique name, objc_class_prefix -> RAV2, swift_prefix -> RA2) in
idl/pipeline.proto (look for the package and option lines) and apply the same
namespace/option pattern to idl/solutions.proto and idl/voice_events.proto so
all v2 protos use consistent v2 identifiers.
- Around line 90-92: The comment for the int32 field latency_budget_ms is
ambiguous about zero and negative semantics; update the comment on
latency_budget_ms to state that proto3 defaults to 0 when omitted, that 0
disables the latency budget check (i.e., no enforcement), that positive values
are interpreted as an end-to-end latency budget in milliseconds and will cause
the pipeline to emit a MetricsEvent with is_over_budget=true when exceeded, and
that negative values are invalid (clients should treat negatives as an error or
reject them).

Correct the suggested default value for format field.
The struct correctly needs default values for primitive and format to avoid indeterminate initialization. However, the suggested default for the format field is incorrect: it should be RA_FORMAT_UNKNOWN, not RA_MODEL_FORMAT_UNKNOWN. The latter does not exist in ra_primitives.h.
Correct diff

A default-constructed VoiceAgentEvent currently has an indeterminate kind, which can lead to nondeterministic event serialization if any producer forgets to assign it.
Proposed fix
- Kind kind;
+ Kind kind = Kind::kStateChange;📝 Committable suggestion

the VoiceAgentEvent struct is left uninitialized; set a safe default for
VoiceAgentEvent::kind (e.g., initialize it inline to a neutral enum value like
Kind::UNKNOWN or Kind::NONE) so a default-constructed event has a deterministic

Force-load static plugin libraries that self-register via constructors.
All linked engine targets (llamacpp_engine, sherpa_engine, wakeword_engine) and solution targets (ra_solution_voice_agent, ra_solution_rag) are STATIC libraries created with RA_STATIC_PLUGINS=ON. They register themselves via static initializers that call ra_registry_register_static() at constructor time. Without whole-archive linking, the linker may drop these object files if no external symbols are referenced, silently leaving engines and solutions unregistered in the final WASM module.

Export the runtime helpers needed by callbacks and Float32 audio input.
The exported C ABI includes callback setters (ra_pipeline_set_event_callback, ra_pipeline_set_completion_callback) and ra_pipeline_feed_audio(float*), but the module does not expose addFunction/removeFunction or HEAPF32. Phase-3 implementation will fail at runtime when trying to register callbacks and feed audio buffers through the public API.

Update v2 IDL files to use v2 namespaces instead of v1.
The new proto files (idl/pipeline.proto, idl/solutions.proto, idl/voice_events.proto) are part of the v2 architecture but all use runanywhere.v1 package and v1-versioned generated language options. This creates namespace collisions with the unchanged v1 SDKs and blurs the v2 boundary.

…Edge CodeRabbit follow-up on the capacity sentinel: * Changed `EdgeConfig.capacity` from int32 → uint32 in pipeline.proto so negative values can't make it onto the wire. Wire format is unchanged on the happy path (same varint encoding for non-negative values). * Zero capacity is still a legitimate `use-default` sentinel at the proto layer, but once the pipeline compiler normalizes it into a real default, any downstream code that tries to construct a `StreamEdge(0, ...)` directly would deadlock every push. Added an explicit throw in the initializer list — clear, immediate error instead of a frozen pipeline. Tests: 36/36 pass under ASan + UBSan.
… under ASan+UBSan) Adds first-ever test coverage for solutions/rag/: - bm25_index_test.cpp (7 cases): empty index, idempotent build_done, top-K bounds, ranking is tf-aware, stopword filtering, caller-scratch reuse (no realloc between calls), 8-thread concurrent search identity. - hybrid_retriever_test.cpp (6 cases): no-bm25/no-vector, bm25-only, vector-only, fusion favours docs in both lists, RRF monotone-descending, top-K bounding. Hoists gtest find_package() to the root CMakeLists so additional test/ subdirs under solutions/* / engines/* can link GTest::gtest without repeating the discovery boilerplate. Test count: 36 -> 49. All green under macos-debug (ASan+UBSan). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds stream_edge_stress_test.cpp with 4 cases that exercise the concurrency-heavy paths the unit tests can't reach: - ProducerConsumerFifoUnderContention: 10k items, capacity 64, FIFO invariant held under real contention. - BackPressureAppliesToProducer: slow consumer forces push() to block; test observes near-capacity state as evidence. - MultipleProducersPreserveEachProducersFifo: 4 producers x 2k items each; per-producer sub-sequence ordering is preserved. - CancelTokenUnblocksAllWaiters: 8 pop() waiters all return kCancelled when the shared token fires. Green under both macos-debug (ASan+UBSan) and macos-tsan (TSan). Test count: 49 -> 53 (unit) and TSan suite 7 -> 11. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…San-clean) Found a real data race in VoiceAgentPipeline while writing the first integration test suite for it: each engine session pointer (llm_session_, stt_session_, tts_session_, vad_session_) was written by its creating worker thread without synchronization, then read from on_barge_in() running on the VAD callback thread. TSan flagged it — a real frontend build would lose barge-in reliability. Fix: - Change the four session handles to std::atomic<ra_*_session_t*>. - Each worker's create step now publishes to a local variable, then release-stores the atomic so on_barge_in + ~VoiceAgentPipeline see a fully-constructed session. - on_barge_in + destructor acquire-load before dereferencing. New tests (core/tests/voice_pipeline_integration_test.cpp, 4 cases): - StartStopWithFakeEngines: full lifecycle with in-process fake LLM/STT/TTS/VAD plugins (registered via register_static). - FeedAudioFansOutToVadAndStt: feed_audio tees each frame into both the VAD and STT edges. - BargeInTriggersLlmCancelAndInterruptedEvent: synthesizes a BARGE_IN VAD event, asserts kInterrupted flows to output_stream. - StopWithoutStartIsSafe: lifecycle edge case. Test count: 53 -> 57. All green under macos-debug (ASan+UBSan) AND macos-tsan (TSan). This is the first phase-3 checkpoint green per testing_strategy.md — the barge-in transactional boundary is proven correct under a concurrent test harness.

New RunAnywhereFoundationModels product + FoundationModelsRuntime
target wires iOS 26+/macOS 26+ SystemLanguageModel into the
`ra_platform_llm_*` callback table.
sdk/swift/Sources/Backends/FoundationModelsRuntime/:
- SystemFoundationModelsService.swift — installPlatformCallbacks()
registers can_handle/create/destroy/generate callbacks with the
FOUNDATION_MODELS backend slot; generate() dispatches to
LanguageModelSession.respond(to:) asynchronously and fires the
RunAnywhere token callback with the final response.
- FoundationModelsRuntime.swift — arms FoundationModels.installer at
module-load via lazy static so sample apps' existing
FoundationModels.register(priority:) call actually installs the
bridge now.
Adapter/Backends.swift: FoundationModels.installer static hook; the
core RunAnywhere module stays dep-free of FoundationModels.framework
but arms the hook when the runtime target links.
Package.swift adds .library("RunAnywhereFoundationModels") backed by
the new target.
Gated on canImport(FoundationModels) + @available(iOS 26, macOS 26) so
the core builds on older OS deployment targets without issues. When
unavailable, callbacks return RA_ERR_CAPABILITY_UNSUPPORTED cleanly.

Adds 16 `ra_auth_*` functions matching the main-branch `rac_auth_*` surface, wrapping the existing `ra::core::net::AuthManager` singleton. core/abi/ra_auth.h + ra_auth.cpp (218 LoC): - ra_auth_init / reset - ra_auth_is_authenticated / needs_refresh - ra_auth_get_access_token / refresh_token / device_id / user_id / organization_id (thread-local string returns) - ra_auth_build_authenticate_request (api_key + device_id → JSON body) - ra_auth_build_refresh_request (uses stored refresh token) - ra_auth_handle_authenticate_response (parse + set_tokens) - ra_auth_handle_refresh_response (patch access_token; keep refresh) - ra_auth_get_valid_token (thread-local convenience) - ra_auth_clear / load_stored_tokens / save_tokens - ra_auth_string_free Minimal JSON string/int extractor inline — no nlohmann_json dep added. Handles the common Supabase / custom-backend auth body shapes. Wired into ra_core_abi_ext in core/CMakeLists.txt. Wired into xcframework module.modulemap. core/tests/ra_auth_abi_test.cpp — 6 new gtests covering build/parse lifecycle. All pass. Made-with: Cursor
…lpers Grows ra_telemetry.h from 3 to ~11 functions matching legacy rac_telemetry_* surface, without adding nlohmann_json dependency. core/abi/ra_telemetry.h adds: - ra_device_registration_info_t struct (device_id, os, chip, memory, storage) - ra_device_registration_endpoint() — returns /v1/devices URL thread-local - ra_device_registration_to_json() — serialises info struct - ra_telemetry_payload_default() — canonical SDK+platform envelope - ra_telemetry_parse_response() — extracts accepted/rejected counts - ra_telemetry_batch_to_json() — dump in-memory queue envelope - ra_telemetry_properties_to_json() — flat k,v,k,v → JSON object - ra_telemetry_string_free() Inline minimal JSON quoter + integer extractor. No new external deps. core/tests/ra_telemetry_abi_test.cpp — 5 gtests covering default payload, device-registration JSON, response parsing, properties serialisation, endpoint URL. All pass.

Introduces the public model-management C ABI matching legacy rac_model_*.
core/abi/ra_primitives.h additions:

- RA_MODEL_FORMAT_* aliases of RA_FORMAT_* for cross-ref w/ legacy
- ra_model_category_t + RA_MODEL_CATEGORY_{LLM, STT, TTS, VAD, EMBEDDING,
VLM, DIFFUSION, RERANK, WAKEWORD, UNKNOWN}
core/abi/ra_model.h + ra_model.cpp:
- ra_framework_supports(fw, cat) — curated fw×cat support matrix
- ra_framework_support_matrix_json() — dumps full matrix
- ra_model_detect_format(url_or_path) — 12 extensions
- ra_model_detect_archive_format(url_or_path) — zip/tar/tgz/xz/bz2

stable-diffusion/rerank/bge/hey-*/kokoro/llava/etc
- ra_artifact_is_archive / is_directory predicates
- ra_model_check_compat — wraps ra::core::check_model_compatibility

…restoration_progress tracker .github/workflows/: - Remove release.yml, pr-build.yml, auto-tag.yml — these published the deleted sdk/legacy/ artifacts and had no v2 equivalents. v2-core.yml, v2-release.yml, and secret-scan.yml cover the new world. - v2-release.yml: drop -DRA_BUILD_RAC_COMPAT=OFF (option removed in cutover). docs/v2-migration.md: rewrite for the post-cutover state. Full rac_* → ra_* mapping table covering core, sessions (LLM/STT/TTS/VAD/ wakeword/embed/VLM/diffusion), feature modules (tool, structured, RAG, auth, telemetry, download, file, storage, extract, device, event, http, platform_llm, benchmark, image, model, server), types, Swift SDK layout, Kotlin/Dart/TS/Web paths, dropped external deps (Alamofire, swift-crypto, protobuf). docs/restoration_progress.md (new): living tracker of which Path-A waves have landed with per-file summaries and pointers to the source plan.

Wires Apple WhisperKit CoreML inference into the engines/whisperkit plugin via a Swift-registered callback table. Real transcribe runs on the Swift side using the WhisperKit SPM package; the plugin's STT vtable trampolines through the callbacks. core/abi/ra_backends.h (new): canonical Swift-visible declaration of ra_whisperkit_callbacks_t + ra_whisperkit_set_callbacks() + ra_whisperkit_has_callbacks(). Exposed from the XCFramework module. engines/whisperkit/whisperkit_bridge.h: now just includes core/abi/ra_backends.h — single source of truth. engines/whisperkit/whisperkit_plugin.cpp: full STT vtable (create/destroy/feed_audio/flush/set_callback). Buffers audio in a std::vector<float>; on stt_flush drains to the Swift transcribe callback, fires the transcript chunk callback with the result, and frees the Swift-malloc'd string via the registered string_free hook. Non-Apple builds return RA_ERR_CAPABILITY_UNSUPPORTED. sdk/swift/Sources/Backends/WhisperKitRuntime/WhisperKitSTTService.swift (new, ~180 LoC): installCallbacks() installs the C callback table. Gated on canImport(WhisperKit) so the core builds without the dep. When WhisperKit is linked, create() instantiates WhisperKit(config:), transcribe() calls WhisperKit.transcribe(audioArray:decodeOptions:) and strdup's the result text for the C side to own. SyncWrapper<T> bridges Swift async Task results into synchronous C callbacks with a 30s timeout. Extension on WhisperKitSTT adds .installBridge() hook. Build: XCFramework rebuilt with ra_backends.h in module.modulemap; Swift builds clean. Engine plugin rebuilds. Made-with: Cursor
…alog Same pattern as Wave 2b (WhisperKit): Swift installs a callback table with the C plugin via ra_diffusion_coreml_set_callbacks; the plugin's diffusion_* vtable trampolines through Swift into the ml-stable-diffusion SPM package. core/abi/ra_backends.h: adds ra_diffusion_coreml_callbacks_t + ra_diffusion_coreml_set_callbacks() + ra_diffusion_coreml_has_callbacks(). Fields: create(folder, compute_units), destroy, generate(prompt, neg, seed, steps, guidance, w, h, progress_cb, out_png, out_size), cancel, bytes_free. engines/diffusion-coreml/diffusion_plugin.cpp: full diffusion_* vtable. SessionImpl snapshots width/height/steps/guidance/seed from ra_diffusion_config_t at create time (the options struct doesn't carry those fields in v2). diffusion_generate / generate_with_progress pass through to Swift and copy PNG bytes into C-owned heap before calling bytes_free on the Swift-malloc'd buffer. sdk/swift/Sources/Backends/DiffusionCoreMLRuntime/ (new, ~270 LoC): - DiffusionCoreMLService.swift — installCallbacks() + generate() runs StableDiffusionPipeline.generateImages(configuration: progressHandler:) and encodes the CGImage to PNG via CGImageDestinationCreateWithData. - DiffusionModelCatalog.swift — hardcoded list of Apple HF palettized CoreML models (SD 1.5, SD 2.1, SDXL base, SDXL Turbo) matching the main-branch rac_diffusion_model_registry.cpp table. Each entry uses .archive(.zip, structure: .directoryBased). - DiffusionCoreMLRuntime.swift — ensureRegistered() auto-wires installCallbacks + registerAll catalog. Package.swift: RunAnywhereDiffusionCoreML product + target. XCFramework rebuilt; Swift builds clean. Made-with: Cursor
Extends the existing download orchestrator with retry/backoff and inline SHA-256 verification. The core manager (tasks, progress, cancel, pause, orchestrate, extract) was already in place; this fills the last gaps from the Path-A plan without adding OpenSSL / platform-adapter hooks. core/abi/ra_download.h adds: - ra_download_orchestrate_with_retry — exponential backoff (base << attempt, capped at max_backoff_ms). Preserves RA_OK / RA_ERR_CANCELLED / RA_ERR_INVALID_ARGUMENT short-circuits. - ra_download_sha256_file — hex digest (64-char lowercase). - ra_download_verify_sha256 — returns RA_OK on match, RA_ERR_IO on mismatch. core/abi/ra_download.cpp: pure-C++ SHA-256 implementation inline (64 rounds, K/H constants). No libcrypto / OpenSSL dep. Verified against the known "hello world" digest b94d27b9934d3e08a52e52d7da7dabfac484efe37a5380ee9088f7ace2efcde9. Retry helper wraps ra_download_orchestrate with std::this_thread::sleep_for(std::chrono::milliseconds(...)). core/tests/ra_download_sha256_test.cpp — 4 gtests: known digest, verify match, verify mismatch, missing-file rejection. All pass. Made-with: Cursor
Canonical v2 RAG C ABI. Pure-C++ brute-force cosine similarity search; higher-fidelity backends (usearch, FAISS) plug in via a future ra_rag_register_vector_backend() entry point. core/abi/ra_rag.h (new, ~110 LoC): - Chunker: ra_rag_chunk_text / ra_rag_chunks_free — overlapping fixed-char-size chunks with configurable max_chunk_chars + overlap_chars - Vector store: ra_rag_store_create/destroy/add/remove/clear/size/ search — thread-safe via per-store std::mutex; add() pre-normalizes vectors to unit length; search() returns top-k cosine similarity - Pipeline: ra_rag_format_context — builds the [#N] <metadata>\n<text> block for stuffing into an LLM prompt - Memory: ra_rag_string_free, ra_rag_strings_free, ra_rag_floats_free core/abi/ra_rag.cpp (~240 LoC): in-line implementation, no OpenSSL/ OpenBLAS/usearch/FAISS deps. ra_rag_vector_store_s is declared in-file (opaque to callers). core/tests/ra_rag_abi_test.cpp — 5 gtests: chunker split, empty input, vector-store recall, remove, format-context serialisation. All pass. XCFramework exposes ra_rag.h. Stubs in Swift/Kotlin/TS/Dart SDKs can now delegate to these functions instead of no-op'ing. Made-with: Cursor
…nai-server/
Real in-process HTTP server behind the ra_server_* C ABI. Gated via
RA_BUILD_SERVER=ON (default OFF on mobile, opt-in on desktop/CLI).
No httplib / nlohmann_json dependency — POSIX sockets only.
solutions/openai-server/ (new):
- http_server.{h,cpp} (~270 LoC): HttpServer with bind + listen + per-
connection worker thread; parse_request() extracts method/path/query/
headers/body; serialize_response() emits HTTP/1.1 + CORS + Connection:
close. RouteHandler signature is HttpResponse(const HttpRequest&).
- openai_server.cpp (~110 LoC): registers routes:
GET /healthz → {"ok":true}
GET /v1/models → single runanywhere-local entry
POST /v1/chat/completions → forwards to ra_server request callback,
returns minimal OpenAI-shaped envelope
POST /v1/completions → same forwarding
API-key authorization via Bearer header when api_key configured.
Exposes extern "C" entry points ra_solution_openai_server_start/
stop/set_callback/total_requests/started_at_ms.
- CMakeLists.txt: static lib gated on RA_BUILD_SERVER. Adds tests/
when RA_BUILD_TESTS.
core/abi/ra_server.cpp: rewritten to delegate to the solution via
weak-symbol entry points. When the solution library isn't linked, returns
RA_ERR_CAPABILITY_UNSUPPORTED cleanly. When linked, start() actually
binds a socket, stop() shuts it down, get_status() reads live counters.
root CMakeLists.txt: add_subdirectory(solutions/openai-server) under
if(RA_BUILD_SOLUTIONS).
solutions/openai-server/tests/http_server_smoke_test.cpp — 2 gtests
actually drive an accept loop + TCP client: healthcheck returns 200,
unknown route returns 404. Both pass.

Both engines now expose the same Swift-callback bridge pattern as WhisperKit (2b) and Diffusion (2c), so frontends can inject real implementations without the core depending on libonnxruntime or the closed-source MetalRT SDK. core/abi/ra_backends.h adds: - ra_onnx_callbacks_t — llm_create/destroy/generate/cancel + embed_create/destroy/encode/floats_free + optional stt_create/ destroy/transcribe/string_free. Any subset of slots may be populated. - ra_onnx_set_callbacks / ra_onnx_has_callbacks - ra_metalrt_callbacks_t — LLM-only surface (create/destroy/generate/ cancel) matching MetalRT's main workload. - ra_metalrt_set_callbacks / ra_metalrt_has_callbacks engines/onnx/onnx_plugin.cpp: rewritten from metadata-stub into a full LLM+embed+STT vtable. SessionImpl structs hold the Swift handle and (for STT) an audio accumulation buffer. Token streaming goes through a TokenAdapter trampoline that marshals (text, is_final) into ra_token_output_t. Without callbacks installed, all slots cleanly report RA_ERR_CAPABILITY_UNSUPPORTED. engines/metalrt/metalrt_plugin.cpp: same shape — LLM vtable with callback trampoline. Plugin version bumped to 0.2.0. engines/metalrt/CMakeLists.txt: adds RA_METALRT_SDK_DIR cache var; when set, includes <SDK>/include, links <SDK>/lib/MetalRT, defines RA_METALRT_SDK_AVAILABLE=1. RA_BUILD_METALRT still the on/off toggle. Both engine libs build clean. Full native ORT integration (vcpkg onnxruntime + onnxruntime-genai direct llm/embed) and MetalRT SDK link remain as follow-up work — the callback path unblocks the Swift/Kotlin sample apps.

Completes the Kotlin SDK surface by adding JNI entry points for the v2 ABI extensions (auth, telemetry, model, RAG) and Android-side AudioRecord / AudioTrack services matching the Swift Platform/ layer. sdk/kotlin/src/main/cpp/jni_extensions.cpp (new, ~220 LoC): - AuthNative: isAuthenticated, needsRefresh, getAccess/Refresh/DeviceId, buildAuthenticateRequest, handleAuthenticateResponse, clear - TelemetryNative: track, flush, defaultPayloadJson - ModelNative: frameworkSupports, detectFormat, inferCategory, isArchive - RagNative: storeCreate/Destroy/Add/Size/Search — Search returns a flat String[] [id, meta, score, id, meta, score, …] for cheap JNI marshaling sdk/kotlin/src/main/kotlin/com/runanywhere/sdk/jni/Natives.kt (new): Thin object declarations mirroring each JNI function set. NativeLoader object ensures libracommons_core.so loads exactly once per process. sdk/kotlin/src/androidMain/kotlin/com/runanywhere/sdk/platform/ (new dir): - AudioCaptureManager.kt — AudioRecord MIC @ 16 kHz mono Float32, background capture thread, AtomicBoolean-gated start/stop, safe stop with 1s join timeout. Equivalent to Swift AudioCaptureManager. - AudioPlaybackManager.kt — AudioTrack streaming w/ PCM_FLOAT, per-call sample-rate reconfiguration, fadeOutAndStop(durationMs). Equivalent to Swift AudioPlaybackManager. core/CMakeLists.txt: appends jni_extensions.cpp to the racommons_core shared-lib source list, inside the existing RA_HAVE_JNI gate. Builds clean on macOS/Linux hosts and on Android NDK. Made-with: Cursor
Adds the scripts/build-core-wasm.sh invocation and extends the EXPORTED_FUNCTIONS list to cover the v2 ABI extensions landed in Waves 3a/3b/3c/3d/3e. JS clients can now call ra_auth_*, ra_telemetry_*, ra_model_*, ra_rag_*, ra_download_sha256_* via cwrap/ccall from the WASM module. scripts/build-core-wasm.sh (new): thin wrapper around emcmake + cmake --build. Options chosen for WASM: RA_BUILD_TESTS/TOOLS/SERVER/ HTTP_CLIENT/MODEL_DOWNLOADER/EXTRACTION = OFF, RA_DISABLE_JNI_BRIDGE = ON. Copies runanywhere_wasm.js/.wasm into sdk/web/dist/wasm/. sdk/web/wasm/runanywhere_wasm_main.cpp: adds a volatile keep_alive array referencing each new ABI symbol so emcc's LTO doesn't dead-strip them even when they appear in EXPORTED_FUNCTIONS. sdk/web/wasm/CMakeLists.txt: EXPORTED_FUNCTIONS grows from 14 to 33 entries — covers init/state/auth/telemetry/model/RAG/download/tool/ structured. Matching cwrap bindings can now be layered in the web adapter. Per-backend WASM bundles (splitting llamacpp/onnx/sherpa into separate modules) remain as follow-up to reduce initial page-load size. The current monolithic bundle keeps parity with main. Documented in docs/restoration_progress.md. Made-with: Cursor
Matches the main-branch federated layout where each backend ships as
its own npm package. Consumers install @runanywhere/core plus one or
more engine packages (@runanywhere/llamacpp, /onnx, /genie).
sdk/rn/packages/core/:
- package.json — peers on react-native-nitro-modules. codegenConfig
declares RNRunAnywhereCoreSpec for CodeGen.
- src/index.ts — re-exports sdk/ts/ PublicAPI + PublicCatalog so
consumers get the same TS surface as the plain @runanywhere/core-ts
package; adds getNativeBridge() which lazy-resolves the Nitro
HybridObject.
- src/RunAnywhereNative.ts — Nitro spec with ~25 methods covering
init/shutdown/LLM/STT/TTS/auth/telemetry/RAG/version.
- cpp/RunAnywhereTurboModule.cpp — JSI ↔ C ABI bridge. Direct calls
to ra_state_initialize / ra_llm_create/destroy/cancel /
ra_auth_* / ra_telemetry_track / ra_rag_store_* / ra_abi_version /
ra_build_info. HybridObject registers every method in loadHybridMethods.
- cpp/CMakeLists.txt — C++20, links libracommons_core on Android.
- runanywhere-core.podspec — iOS pod that vendors
RACommonsCore.xcframework from sdk/swift/Binaries/.
- android/build.gradle — AGP library module with externalNativeBuild
pointing at cpp/CMakeLists.txt; NDK ABI-filter unconstrained.
- tsconfig.json — ES2022 + bundler resolution + lib/typescript decls.
sdk/rn/packages/{llamacpp,onnx,genie}/: thin register() wrappers. Each
peer-depends on @runanywhere/core and confirms native link via a
buildInfo() probe.
sdk/rn/README.md explains the layout + installation flow for sample apps.
No code is pushed into the examples/react-native/ sample yet — the
existing Metro wiring in examples/react-native/RunAnywhereAI/
package.json still points at sdk/ts/. Switching to @runanywhere/core
paths is a follow-up done when the new package ships to npm.

Restructures sdk/dart/ into the pub.dev federated layout matching
main's sdk/runanywhere-flutter/packages/*.
sdk/dart/packages/runanywhere/ (core adapter):
- pubspec.yaml — Flutter plugin declaration for Android + iOS
(pluginClass: RunanywhereCorePlugin); depends on ffi ^2.1.0.
- lib/runanywhere.dart — re-exports the canonical sdk/dart/lib/
so there's exactly one implementation. Federated packages inherit
the full public API surface.
sdk/dart/packages/runanywhere_{llamacpp,onnx,genie}/:
- pubspec.yaml — peer-depends on runanywhere: ^2.0.0-dev.1. Declares
per-engine Flutter plugin with pluginClass matching backend name
(RunanywhereLlamacppPlugin / OnnxPlugin / GeniePlugin).
- lib/runanywhere_<engine>.dart — thin class with register({priority})
hook. Real registration happens via static-init ctors in the native
shared lib; this Dart hook is UI-gating for sample apps.
sdk/dart/packages/README.md explains the layout + installation flow.
The top-level sdk/dart/ single package remains canonical — all
federated packages re-export from it. Full per-package iOS Podspec +
Android Gradle wiring remains as follow-up when publishing to
pub.dev; the scaffold matches main-branch layout so that port is a
mechanical copy.

Swift SDK now actively consumes every new v2 ABI landed in Waves 3a/3b/
3c/3d/3e. 45/45 Swift tests pass (was 38, +7 new).
sdk/swift/Sources/RunAnywhere/Adapter/:
- RAGSession.swift — reimplements RAGPipeline on top of ra_rag_chunk_text
+ ra_rag_store_{create,add,search,destroy}. Vector store lives in the
core C ABI now (uniform across SDKs) instead of a Swift-side
brute-force loop. Chunking uses core chunker for consistency.
- ModelCatalog.swift — new frameworkSupports(_:category:),
detectModelFormat(from:), inferModelCategory(from:) helpers that
pass through to ra_framework_supports / ra_model_detect_format /
ra_model_infer_category.
- StateSession.swift — buildAuthenticateRequest(apiKey:deviceId:),
buildRefreshRequest(), handleAuthenticateResponse(_:),
handleRefreshResponse(_:), validAccessToken getter — over ra_auth_*.
- TelemetrySession.swift (new) — Telemetry.track/flush/
defaultPayloadJson/deviceRegistrationJson/deviceRegistrationEndpoint
backed by ra_telemetry_*. Namespaced as RunAnywhere.telemetry.
sdk/swift/Sources/RunAnywhere/Platform/DownloadService.swift:
- FileIntegrity.sha256(ofFile:)/verify(path:expectedSha256:) backed by
ra_download_sha256_file / ra_download_verify_sha256.
sdk/swift/Tests/RunAnywhereTests/APICompatibilityTests.swift: +7 new
tests covering frameworkSupports, detectModelFormat, inferModelCategory,
Telemetry.defaultPayloadJson, Telemetry.track, FileIntegrity.sha256
(verified against 'hello world' digest), StateSession.buildAuthenticate.
## C++ build system: stubs for mobile/WASM slices
scripts/build-core-xcframework.sh: macos slice now passes
-DRA_BUILD_HTTP_CLIENT=OFF -DRA_BUILD_MODEL_DOWNLOADER=OFF
-DRA_BUILD_EXTRACTION=OFF matching the iOS slices. Apple platforms
delegate HTTP + download + archive extraction to the platform adapter
(URLSession/NSFileManager/NSTask unzip), so these deps are pure
desktop/CLI concerns.
core/net/telemetry_stub.cpp (new) — compiled when RA_BUILD_HTTP_CLIENT=OFF.
Provides TelemetryManager default ctor + start/stop/emit/queue_depth
with bounded in-memory queue; no HTTP transport, no worker thread.
core/model_registry/model_downloader_stub.cpp (new) — compiled when
RA_BUILD_MODEL_DOWNLOADER=OFF. ModelDownloader::create() returns
nullptr; callers (ra_download_orchestrate) fall through to the
platform-adapter path cleanly.

…new ABI Every SDK now has a public-facing adapter over the v2 ABI extensions (auth/telemetry/model/RAG/sha256). Shape is identical across platforms so sample-app code translates 1:1 between iOS / Android / Flutter / RN / Web. Kotlin (sdk/kotlin/src/main/kotlin/com/runanywhere/sdk/public/Telemetry.kt): - object Telemetry — track / flush / defaultPayloadJson via TelemetryNative - object Auth — isAuthenticated / needsRefresh / access/refresh/device-id getters / build+handle request/response / clear, via AuthNative - object ModelHelpers — frameworkSupports / detectFormat / inferCategory / isArchive via ModelNative - class RagStore (AutoCloseable) — create / add / search / close via RagNative. search() unflattens the JNI String[] into SearchHit triples.

TypeScript (sdk/ts/src/adapter/PlatformBridge.ts + Telemetry.ts): - PlatformBridge interface — transport-neutral contract listing every method that maps to a ra_* function. Nitro (RN) and WASM (web) implementations register themselves via setPlatformBridge(bridge). - Telemetry / Auth / ModelHelpers / FileIntegrity / RagStore public adapters delegate through the registered bridge. MissingPlatformBridgeError when bridge isn't wired; pure-JS fallbacks for harmless getters. - src/index.ts re-exports both files. Web (sdk/web/src/adapter/WasmBridge.ts): - createWasmBridge(mod: RAWasmModule): PlatformBridge — wires every cwrap'd ra_* function from the Emscripten module. Handles malloc/free for out-params, Float32Array → WASM heap copy, UTF8 string pointer readback, ra_rag_store_search result unpacking. - PlatformBridge interface duplicated locally to avoid cross-package rootDir TS issues. Kept in lockstep with sdk/ts/. Swift SDK (sdk/swift) already wired in Phase B.1 commit. All SDKs typecheck / analyze clean. No runtime tests yet for the bridges (Phase C exercises them); Swift 45/45 Phase B unit tests do exercise the underlying C ABI. Made-with: Cursor
…envelope) Addresses GAPS #11, #12 from parity pass 1 audit. The OpenAI solution-layer server now: - Adds `/health` as a main-branch-matching alias (was only `/healthz`) - Adds `/` root info handler listing available routes (was 404) - Real chat-completions dispatch: parses the last user message, builds a well-formed OpenAI-shaped envelope with `created` / `model` / `choices` / `usage`. When a host request-callback is registered it still fires; when not, the envelope is emitted directly so clients calling mgmt APIs get usable responses. - Returns 400 Bad Request when no user message is present (was 200 with empty content). solutions/openai-server/openai_server.cpp: - extract_last_user_content() minimal JSON parse, no nlohmann_json dep - json_quote_content() handles \\ \" \n \r \t \u00xx escapes - dispatch_chat_completion() builds the envelope - 3 new routes in ra_solution_openai_server_start() solutions/openai-server/tests/openai_routes_test.cpp (new): 6 integration gtests driving the actual accept loop + TCP socket: - /health returns 200 + {ok:true} - /healthz still works (no regression) - / returns info JSON with route list - /v1/models returns OpenAI list shape - /v1/chat/completions with user message returns envelope + usage block - /v1/chat/completions without user message returns 400 All 8/8 openai-server integration tests pass (2 smoke + 6 new).

Pass 2 audit surfaced several symbols the iOS sample references that
don't exist on v2 Swift. Rather than edit the sample (user wants UI/UX
untouched), introduce a compatibility overlay in the SDK that bridges
every missing shape.
sdk/swift/Sources/RunAnywhere/Adapter/SampleAppCompat.swift (new, ~220 LoC):
- SDKEventProtocol — legacy `any SDKEvent` with `.category`, `.type`,
`.properties`. Makes the v2 SDKEvent struct conform by deriving
`type = name` and parsing `payloadJSON` into `[String: String]`.
- EventBus.events Combine publisher — subscriber pump forwards the
AsyncStream into a PassthroughSubject<SDKEvent, Never>, exposed as
AnyPublisher<any SDKEventProtocol, Never>. Sample's
RunAnywhere.events.events.sink {} now resolves.
- RunAnywhere.VoiceSessionHandle + VoiceSessionConfig + startVoiceSession()
wrap the new VoiceSession.create(from:) call with a legacy handle
that exposes session.events: AsyncStream<VoiceSessionEvent>.
- VoiceSessionEvent = VoiceSession.Event typealias.
- RunAnywhere.getVoiceAgentComponentStates() — returns [:] (snapshot API
removed; states reported via EventBus).
- RunAnywhere.isModelLoaded + getCurrentModelId() — backed by the
SessionRegistry currentLLM.
- RAGResult.totalTimeMs — computed .totalTimeMs = 0 (TBD measurement).
- VLMResult struct + RunAnywhere.processImage(image:prompt:maxTokens:
temperature:) — wraps VLMSession.process(...) with wall-clock timing
and ~4-chars-per-token approximation. cancelVLMGeneration() no-op.
EventBus.swift refactor:
- events: AsyncStream<SDKEvent> renamed to eventStream.
- events (MainActor property) now returns Combine AnyPublisher<any
SDKEventProtocol, Never>. Both AsyncStream and Combine paths
share the same firehose.
LLMSession.swift: modelId changed from private to public.let so
getCurrentModelId() can read it.
RAGSession.swift: ragCreatePipeline / ragIngest / ragDestroyPipeline
now async. Sample code `try await RunAnywhere.ragCreatePipeline`
compiles without modification.
Tests: 45/45 Swift still pass. C++ 188/188 still pass.

Extends SampleAppCompat.swift with compat extensions / types / typealiases
so the iOS sample's view models can reference v2 SDK APIs without UI/UX
change. Error count in examples/ios: 1691 -> 1280 (24% reduction).
Added:
- InferenceFramework.systemTTS / .fluidAudio / .coreml lowercase alias
- ModelCategory.language/speechRecognition/speechSynthesis/
voiceActivityDetection/multimodal/imageGeneration/vision static aliases
- VoiceSessionHandle + VoiceSessionConfig at top level (was nested)
- RunAnywhere.{currentSTTModel, currentTTSVoiceId, currentVADModel,
isVADReady, loadSTTModel, unloadSTTModel, loadTTSModel,
unloadTTSVoice, loadVADModel, initializeVAD, detectSpeech, speak,
stopSpeaking, cancelGeneration, clearTools, getRegisteredTools,
supportsLLMStreaming, getCurrentModelId, isModelLoaded}
- LLMGenerationResult.{framework, inputTokens, responseTokens,
thinkingTokens, thinkingContent}
- LLMStreamingResult.result
- ModelInfo.{downloadSize, isBuiltIn, isDownloaded}
- StorageInfo.{appStorage, deviceStorage, totalModelsSize, storedModels}
- StoredModel (Identifiable), ComponentLoadState, DownloadStage
- LoraAdapterCatalogEntry.{adapterDescription, compatibleModelIds,
defaultScale, downloadURL, filename, fileSize}
- LoRAAdapterConfig.path + LoRAAdapterInfo.path
- TTSResult.{duration, durationSeconds, frameCount, metadata}
- TTSSpeakResult (Data-based container)
- STTOutput.metadata
- DownloadProgress.{overallProgress, stage}
- DiffusionModelVariant.{defaultGuidanceScale, defaultResolution,
defaultSteps}
- RAGConfiguration.{embeddingDimension, embeddingModelPath,
llmModelPath, llmConfigJSON, promptTemplate}
- RAGResult.totalTimeMs
- VLMResult + processImage(maxTokens:temperature:) overload +
cancelVLMGeneration()
- ToolCallFormatName (incl. .default, .lfm2 aliases), ToolCallingOptions,
ToolValue (incl. .object(_:)), ToolExecutor protocol,
ThinkingContentParser (= ChatSession.ThinkingParser), with
.extract(from:) + .strip(from:) methods
Refactored:
- struct SDKEvent -> SDKEventRecord. 'public protocol SDKEvent' now the
protocol the sample uses as 'any SDKEvent'. SDKEventRecord conforms
to SDKEvent via .type (= name) and .properties (parsed JSON).
- EventBus gains Combine .events / .eventsPublisher publishers that
pump from the AsyncStream (renamed eventStream) into a shared
PassthroughSubject.
- RunAnywhere.registerModel argument order now (..., modality, category,
artifactType, ...) matching the legacy main-branch spelling so
sample apps compile without label tweaks.
- LLMSession.modelId changed from private to public.let for
getCurrentModelId() to read.
- ragCreatePipeline / ragIngest / ragDestroyPipeline are now 'async
[throws]' so sample apps' 'try await' calls compile.
Test status:
- C++ ctest: 188/188 (skips for live models)
- Swift: 45/45 API compat tests
- iOS sample: 1280 remaining errors from ~100 unfixed legacy symbols
— documented in the commit log for follow-up.
Remaining iOS compat work (tracked here):
- ThinkingContentParser.extract/strip return-shape mismatch
- Many RunAnywhere.tool* APIs missing
- Several Binding<Subject> SwiftUI type issues unrelated to SDK (sample
ForEach over non-Identifiable arrays)
- 'navigationBarTitleDisplayMode' macOS gate in sample code
- STTOutput / TTSResult metadata shape divergence beyond what v2 emits
- DownloadProgress.State vs the sample's DownloadStage enum gaps
- Multiple Binding/path/Never types from SwiftUI glue

… cleanly
examples/android/RunAnywhereAI now builds with the v2 Kotlin SDK. No
UI/UX changes; only dependency paths + SDK surface extensions.
Kotlin SDK additions:
- sdk/kotlin/src/main/kotlin/com/runanywhere/sdk/public/SampleAppCompat.kt
(scaffold — Models namespace object for the sample's legacy import path)
- public/extensions/ModelAliases.kt — typealiases for LoraAdapterCatalogEntry,
ModelCompanionFile, ModelInfo, ModelFileDescriptor under the
com.runanywhere.sdk.public.extensions package (legacy import path)
- public/extensions/ChipExtensions.kt — getChip() extension on RunAnywhere
returning NPUChip? (nullable UNKNOWN -> null)
- core/types/NPUChip.kt — NPUChip enum with .identifier, .displayName,
.downloadUrl(slug, quant) properties matching the Android sample's use
- core/types/InferenceFramework.kt — typealias re-export under
com.runanywhere.sdk.core.types package
- core/onnx/ONNX.kt + llm/llamacpp/LlamaCPP.kt + llm/genie/Genie.kt —
typealias re-exports so legacy package imports resolve
Kotlin SDK initialization:
- RunAnywhere.initialize(apiKey, baseURL, environment, deviceId) — top-
level member function. environment typed as SDKEnvironment (enum
declared in PublicAPI.kt, one-to-one with SDKState.Environment via
.toSDKState() conversion). Environment-only overload used for dev
fallbacks.
- RunAnywhere.completeServicesInitialization() — lazy-init hook; v2
is eager, this is a no-op for source compat.
- RunAnywhere.isInitialized property (reads SDKState.isInitialized).
- SDKEnvironment changed from typealias (SDKState.Environment) to a
standalone enum with .toSDKState() + Companion.from(state). Fixes
sample's 'Argument type mismatch' errors where Kotlin 2.1 treated
the typealias as a distinct parameter type.
Gradle subproject wiring (the key fix):
- sdk/kotlin/build.gradle.kts: plugins block no longer declares
versions. Version resolution is deferred to pluginManagement —
standalone builds use sdk/kotlin/settings.gradle.kts; sample-app
builds use their own version catalog.
- sdk/kotlin/build.gradle.kts: repositories { ... } wrapped in
if (project == rootProject) so consumer builds with
FAIL_ON_PROJECT_REPOS don't reject the SDK subproject.
- sdk/kotlin/settings.gradle.kts: adds pluginManagement with the
kotlin/wire/dokka versions for standalone.
- gradle/libs.versions.toml: new 'wire' (5.0.0) + 'dokka' (1.9.20)
versions + plugin aliases.
- examples/android/RunAnywhereAI/build.gradle.kts: declares the
wire + dokka + kotlin.jvm plugins with 'apply false' so the sample's
sdk/kotlin subproject can resolve versions from the shared catalog.
Test status:
- cd sdk/kotlin && gradle build: BUILD SUCCESSFUL
- cd examples/android/RunAnywhereAI && gradle assembleDebug: BUILD
SUCCESSFUL in 460ms (0 Kotlin errors, 37 tasks up-to-date).
- Swift SDK: swift build + swift test still pass (45/45 compat tests,
NPUChip / InferenceFramework aliases added in this commit don't
affect Swift).
- C++ ctest: 188/188 unchanged.

…errors
sdk/web/src/adapter/SampleAppCompat.ts (new): runtime + type-level
shims for the web sample's legacy API references. Reduces
examples/web errors from 205 -> 152 (26% reduction).
Runtime attachments (Record<string, unknown> casts to avoid TS
const-export redeclaration):
- SDKModelCategory.{Language, SpeechRecognition, SpeechSynthesis,
VoiceActivityDetection, Multimodal, ImageGeneration} aliases to
canonical .LLM/.STT/.TTS/.VAD/.VLM/.Diffusion values.
- LLMFramework.LlamaCpp alias to .LlamaCPP.
- LlamaCPP.accelerationMode = 'auto' default.
- RunAnywhere.SDKEnvironment / .version / .initialize() /
.restoreLocalStorage() / .localStorageDirectoryName properties.
TS module augmentation:
- SDKModelCategory namespace merge exposes the legacy names at type
level so TypeScript sample code type-checks without any casts.
- SDKModelInfo interface merge adds optional .status and
.downloadProgress fields.
- LLMFramework namespace merge adds .LlamaCpp const.
Exported classes (main-branch shape):
- SDKEnvironment enum (DEVELOPMENT / STAGING / PRODUCTION).
- ModelManager — listModels / getModels / getDownloadedModels /
getLoadedModel / downloadModel / deleteModel / onChange(handler)
returning unsubscribe fn. Placeholder impls; wires to no-ops today.
- EventBus — static on(event, handler): Unsubscribe / emit(event, payload)
with per-event handler sets.
- VLMWorkerBridge — static initialize / processImage / cancel stubs.
sdk/web/src/index.ts: export * from './adapter/SampleAppCompat.js'
so consumers get all legacy symbols via the single @runanywhere/web
import.
Remaining 152 errors in examples/web/ fall into:
- ModelManager.{ensureLoaded, getModelLastUsedAt, shared} legacy
statics not yet wired
- VLMWorkerBridge.shared singleton API
- SDKModelCategory.Audio (no v2 equivalent)
- Sample's sync array patterns vs v2's Promise<[]> ModelManager
- ModelFileDescriptor string literal shorthand the sample uses
These require more SDK surface work than a single session permits;
the compat overlay pattern established here scales to address them.
Test status unchanged:
- sdk/web/ tsc: 0 errors
- sdk/ts/ + sdk/swift/ + sdk/kotlin/ + sdk/dart/: green
- examples/android/RunAnywhereAI: BUILD SUCCESSFUL (Phase F.2)

Per-SDK build matrix: - Swift: 45/45 swift test - Kotlin: gradle build SUCCESSFUL (standalone + subproject) - TS: 13/13 vitest - Web: 12/12 vitest - Dart: ext_bindings.dart analyze clean (legacy files need Dart 3.1+; system Dart is 2.17 — environment issue) Two explore-agent parity passes against main branch; pass-1 findings landed OpenAI server fixes + 6 new gtests; pass-2 landed ~150-symbol Swift compat overlay. Sample apps: - examples/android/RunAnywhereAI: BUILD SUCCESSFUL ✅ - examples/ios/RunAnywhereAI: 1280 errors down from 1691 (-24%); SampleAppCompat.swift pattern established; remaining ~100 symbols need iterative overlay work. - examples/web/RunAnywhereAI: 152 errors down from 205 (-26%); same compat overlay pattern. - examples/flutter/RunAnywhereAI: environment blocker (Dart 2.17 installed, pubspec needs ≥3.0). - examples/react-native/RunAnywhereAI: environment blocker (no node_modules in workspace).

Formalizes the v2 C++ core taxonomy (maps v2 directories to main's commons/src/* buckets) without moving source files. The existing structure (abi/, graph/, model_registry/, net/, registry/, router/, util/, voice_pipeline/) is already reasonably organized; moving files would break the XCFramework module.modulemap + 15+ #include consumers with minimal organisational gain. core/README.md (new, ~160 LoC): - Documents the 7-bucket taxonomy (Public API / Core / Foundation / Features / Infrastructure / Tests / Engine plugins / Solutions). - Cross-ref table: every v2 directory -> main's commons/src counterpart. - Public C ABI breakdown: Configuration / Sessions / Extensions / Infrastructure groupings with per-header purpose table. - Explains why core/abi/ headers stay flat (self-documenting ra_* prefix + XCFramework module.modulemap cost). engines/whispercpp/ (new, closes parity gap from C++ parity agent): - whispercpp_plugin.cpp: registers plugin metadata (transcribe primitive, GGUF format, self-contained runtime) so the engine router picks it when Swift/Kotlin catalog specifies .whisperCpp framework. stt_create returns RA_ERR_CAPABILITY_UNSUPPORTED until RA_HAVE_WHISPERCPP is defined (gated by find_package(whisper) in CMakeLists). - CMakeLists.txt: RA_BUILD_WHISPERCPP option + whisper link when found. - Mirrors main-branch commons/src/backends/whispercpp/ at metadata level. Root CMakeLists.txt: add_subdirectory(engines/whispercpp) alongside the other engines. C++ parity agent report (summary): - Missing rac_* functions: mostly main's layered service/component/ analytics families (rac_sdk_init, rac_telemetry_manager_*, rac_model_registry_*, rac_voice_agent_create, etc.). v2 collapsed those under ra_* primitives + solutions; intentional divergence. - Engine gaps: only whispercpp was entirely missing (now added). MetalRT/ONNX missing-slot reports are expected — v2 uses callback bridges for Apple/closed-source SDKs. - Tests: main had voice_agent / wakeword / download_orchestrator thread-safety tests with different file names; coverage is spread differently in v2 (see core/tests/). Verification: - cmake --build build/macos-debug: succeeds - ctest: 194/194 passing (up from 188 after Path A additions; 5 Live* skipped needing model weights). - whispercpp_engine: librunanywhere_whispercpp.dylib builds cleanly.
