📝 WalkthroughWalkthroughThis PR implements a unified engine plugin system architecture with protocol-buffer based IDL schemas and multi-language code generation. It introduces plugin registration/discovery, hardware-aware engine routing, dynamic/static plugin loading, CI drift-checking for generated artifacts, and corresponding language SDK updates to bridge proto-generated types.

Per review request — all v2 architecture work lives on the one `feat/v2-architecture` branch tracked by PR #494, instead of fragmenting into per-wave sub-branches. Updates `docs/wave_roadmap.md` to encode this contract for future contributors: - Branch: `feat/v2-architecture` (single, long-lived). - PR: #494 (stays open and grows commit-by-commit). - Cadence: one commit per phase, message prefix `feat(gapXX-phaseN)`. - Per-wave milestone: checked-in `docs/gap0X_final_gate_report.md`. - Merge to main: only when GAP 01-08 are all done (GAP 05 opt-in). Refresh the title from "Post-Wave-A roadmap" to "v2 architecture roadmap" to match the broader scope. Note Wave A is now MERGED INTO the branch (not "this branch"). No code changes. Made-with: Cursor

The WhisperKit CMakeLists.txt does not define a backend-specific

While the public callback functions useRAC_API(which has unconditionalvisibility("default")), the plugin entry pointrac_plugin_entry_whisperkit_coremlhas no explicit visibility attribute and relies on default behavior. Add the definition to maintain consistency and ensure robust symbol visibility:target_compile_definitions(rac_backend_whisperkit_coreml PRIVATE RAC_WHISPERKIT_COREML_BUILDING)Then create

Drift check silently passes when Dart is unavailable.
macos-14 runners do not ship with dart preinstalled, so this step emits a warning and generate_dart.sh is never invoked by generate_all.sh. Because the committed Dart bindings under sdk/runanywhere-flutter/packages/runanywhere/lib/generated/** are not regenerated, git diff --exit-code on line 91 reports no drift even when a contributor edits idl/*.proto without regenerating Dart (or hand-edits a generated Dart file). The gate advertised in the workflow header ("any .proto … without regenerating the committed language bindings … this job fails") does not hold for Dart.
Either install Dart unconditionally (e.g., dart-lang/setup-dart@v1) or fail the job when dart is missing rather than warning — the drift guarantee is only as strong as its weakest language.

Align the generated C++ include path with the documented consumer interface.
The script documents that consumers use #include "runanywhere/idl/model_types.pb.h", but the protoc invocation with --proto_path="${REPO_ROOT}/idl" and --cpp_out="${OUT_DIR}" (where ${OUT_DIR} is sdk/runanywhere-commons/src/generated/proto) generates headers directly at that output directory without the runanywhere/idl/ prefix. The CMakeLists.txt target_include_directories() configuration only exposes the bare filenames (e.g., #include "model_types.pb.h"), not the documented path. Any consumer following the documented include path will fail to compile.
Either adjust the protoc invocation to generate files under a runanywhere/idl/ subdirectory, or update the documentation to reflect the actual include paths used in the build.

Make the default-true barge-in flag representable across all generators.
A plain proto3 bool defaults to false and lacks presence semantics, preventing the core (C++) from distinguishing "unset, use default true" from "caller explicitly set false." Although Dart's protoc plugin auto-generates presence tracking, C++ does not, creating inconsistency. Use optional bool to ensure all generators properly preserve presence.

Enforce the pinned tool versions instead of only declaring them.
The script claims byte-identical codegen, but three expected versions (PROTOC_EXPECTED_MAJOR, SWIFT_PROTOBUF_EXPECTED, WIRE_EXPECTED) are unused, and remaining pinned versions allow floating resolution instead of exact matches:
brew/aptinstall unpinned (protoc, swift-protobuf, wire-compiler)npm install "ts-proto@^${TS_PROTO_EXPECTED}"uses caret range, not exact versionpip install "protobuf>=${PYTHON_PROTOBUF_EXPECTED},<5"allows 4.25–4.99.x range, not exact versioncheck_versions()only fails on missingprotoc, not on missing or mismatched protoc-gen-swift, protoc-gen-dart, or ts-proto
Local regeneration can silently drift from CI. --check should validate exact versions and fail consistently on any missing codegen tool.

Pin plugin lifetime while routing.
route() snapshots raw vtable pointers, then dereferences them after the registry lock is gone. A concurrent unregister/dynamic unload can invalidate vt->metadata while scoring or tie-breaking. Hold a registry read lock through scoring, or return a snapshot that ref-counts/pins the plugin handle until routing completes.

134, EngineRouter::route currently grabs raw vtable pointers from
snapshot_for_primitive and then dereferences vt->metadata after the registry
lock may have been released, risking use-after-unload; fix by ensuring the
plugin lifetime is pinned while scoring/sorting: either have
snapshot_for_primitive return a snapshot of ref-counted/pinned plugin handles
(not raw rac_engine_vtable_t*), or acquire and hold the registry read-lock for
the entire scoring and std::sort phase inside EngineRouter::route; update the
loop that builds scored (and the comparator that reads vt->metadata) to use the
pinned handle type or to run while holding the lock so vt->metadata cannot be
invalidated concurrently.

There was a problem hiding this comment.
Use a safe fallback for unknown proto environments.
Mapping unknown or unspecified wire values to development can disable auth/sync and enable dev behavior in production flows. Prefer an explicit development match and default unknowns to production or throw.

Design decision: used protoc_plugin's `whichPayload()` switch instead of the nullable-field pattern (hasUserSaid, hasAudio, ...). The oneof enum gives exhaustive-match guarantees from the analyzer — if a new payload arm is added to voice_events.proto, the switch will fail to compile until the mapper is extended.

File: sdk/runanywhere-react-native/packages/core/src/types/VoiceAgentTypes.ts Mapper 1 — `voiceSessionEventFromProto(event: VoiceEvent)`: Maps to the flat `VoiceSessionEvent` interface (`{ type, timestamp, data? }`). RN has its own 8-variant `VoiceSessionEventType` union that predates the Swift enum, so the mapping targets those values: userSaid → { type: 'transcriptionComplete', data: { transcription } } assistantToken → { type: 'responseGenerated', data: { response } } audio → { type: 'speechSynthesized' } vad VOICE_START → { type: 'speechDetected' } vad others → null state IDLE → { type: 'started' } state STOPPED → { type: 'ended' } state others → null error → { type: 'error', data: { error: message } } interrupted, metrics → null Timestamp: converted from proto's `timestampUs` (microseconds) to JS's `timestamp` (milliseconds) via `Math.floor(us / 1000)`, or Date.now() if the proto timestamp is zero. Mapper 2 (bonus) — `voiceSessionEventKindFromProto(event: VoiceEvent)`: Maps to the richer `VoiceSessionEventKind` discriminated-union, which already in the same file and matches Swift/Kotlin/Dart 1:1. The mapping matches commit 540deec's Swift template exactly: userSaid → { type: 'transcribed', text } assistantToken → { type: 'responded', text } audio → { type: 'speaking' } vad VOICE_START → { type: 'speechStarted' } vad VOICE_END_* → { type: 'processing' } state IDLE → { type: 'started' } state LISTENING → { type: 'listening', audioLevel: 0 } state SPEAKING → { type: 'speaking' } state STOPPED → { type: 'stopped' } state THINKING / UNSPECIFIED → null error → { type: 'error', message } vad BARGE_IN / SILENCE → null interrupted, metrics → null turnCompleted is intentionally unreachable (aggregates multiple events) Both signatures now accept a strongly-typed `VoiceEvent` (from `../generated/voice_events`) instead of the scaffold `unknown`.

Made-with: Cursor
…Swift) Closes the #8 audit-flagged gap: the rac_llm_thinking C ABI was only consumed by Swift (via CppBridge+LLMThinking.swift); Kotlin, Dart, RN, and Web had no bindings. Kotlin is first. After this commit, the Kotlin SDK can parse <think>...</think> blocks with byte-for-byte the same behavior as Swift — critical for cross-SDK streaming UIs that render thinking vs answer content differently. Files changed: sdk/runanywhere-commons/src/jni/runanywhere_commons_jni.cpp Added #include "rac/features/llm/rac_llm_thinking.h". Added 3 JNIEXPORT thunks in a new "LLM Thinking" section: Java_..._racLlmExtractThinking(text) -> String[2] Maps rac_llm_extract_thinking's 4 out-params + 2 out-lens into a typed 2-element array: [0]=response (never null on success), [1]=thinking (null when no <think> block). Copies both strings out of the thread_local C arena before returning. Java_..._racLlmStripThinking(text) -> String Maps rac_llm_strip_thinking's out-params to a single jstring. Java_..._racLlmSplitThinkingTokens(total, response, thinking) -> int[2] Maps rac_llm_split_thinking_tokens's 2 out-params to a jintArray [thinking_tokens, response_tokens]. Passes null to the C side when a String arg is null or empty (per the C ABI contract). sdk/runanywhere-kotlin/src/jvmAndroidMain/kotlin/com/runanywhere/ sdk/native/bridge/RunAnywhereBridge.kt Added matching 3 @JvmStatic external fun declarations in a new LLM THINKING section, with KDoc citing the C ABI return contract for each. New file: sdk/runanywhere-kotlin/src/jvmAndroidMain/kotlin/com/runanywhere/ sdk/foundation/bridge/extensions/CppBridgeLlmThinking.kt Typed Kotlin facade mirroring Swift's ThinkingContentParser naming. Exposes: - `extract(text)` → LlmThinkingExtraction(response, thinking?) - `strip(text)` → String (throws on C-level null-pointer error) - `splitTokens(total, response?, thinking?)` → LlmThinkingTokenSplit( thinkingTokens, responseTokens) All methods are pure + thread-safe (C ABI uses thread_local arena; JNI copies strings out before returning, so multi-thread callers don't race on the shared buffer). Verification (isolated clang++ compile of the 3 thunks): $ clang++ -std=c++17 -c \ -I sdk/runanywhere-commons/include \ -I $JAVA_HOME/include -I $JAVA_HOME/include/darwin \ /tmp/llm_thinking_thunks_check.cpp \ -o /tmp/llm_thinking_thunks_check.o [exit 0; 11KB .o] Kotlin: ReadLints passed (zero linter errors on RunAnywhereBridge.kt + CppBridgeLlmThinking.kt).

New file: sdk/runanywhere-flutter/packages/runanywhere/lib/capabilities/
llm/llm_thinking.dart
Structure:
- 3 FFI typedef pairs (`_ExtractThinkingNative` / `_Dart` etc.)
matching the C signatures in rac_llm_thinking.h exactly:
rac_llm_extract_thinking(text, out_resp, out_resp_len,
out_think, out_think_len)
rac_llm_strip_thinking(text, out_stripped, out_stripped_len)
rac_llm_split_thinking_tokens(total, resp, think,
out_think_tok, out_resp_tok)
- Lazy-cached `_LlmThinkingBindings` class; lookupFunction calls
run once per process on first access.
- Public typed results: `LlmThinkingExtraction`,
`LlmThinkingTokenSplit`.
- `class LlmThinking` with 3 static methods: extract, strip,
splitTokens. All handle calloc+free lifecycle correctly,
including the null-vs-empty-string distinction the C ABI
requires for split_tokens (empty strings are passed as nullptr
so the implementation's `if (!thinking || !thinking[0])`
short-circuit fires correctly).
- `_copyUtf8(ptr, len)` helper copies C thread_local-arena bytes
into a fresh Dart String before the next FFI call could
invalidate the buffer.
Matches Swift's ThinkingContentParser + Kotlin's CppBridgeLlmThinking
APIs 1:1 (method names, result shapes, null semantics).

Web remains (A11).
New interface on the Nitro HybridObject:
sdk/runanywhere-react-native/packages/core/src/specs/RunAnywhereCore.nitro.ts
Added 3 new methods in a new "LLM Thinking" section:
llmExtractThinking(text): Promise<string>
Returns JSON: `{ response, thinking }`
llmStripThinking(text): Promise<string>
Returns the trimmed remainder (empty on error).
llmSplitThinkingTokens(total, responseText, thinkingText): Promise<string>
Returns JSON: `{ thinking, response }` with
`thinking + response == total`.
JSON return shape instead of tuples: Nitro's tuple-return ergonomics
vs JSON.parse are a wash for 2-3-field returns; JSON gives a
schema-stable wire format that's also easy to mock in tests. The
TS facade below parses transparently.
C++ implementation:
sdk/runanywhere-react-native/packages/core/cpp/HybridRunAnywhereCore.hpp
Added 3 method declarations in a new "LLM Thinking" section.
sdk/runanywhere-react-native/packages/core/cpp/HybridRunAnywhereCore.cpp
Added #include "rac_llm_thinking.h".
Added 3 override implementations:
- `llmExtractThinking`: calls rac_llm_extract_thinking, emits
JSON with both fields (thinking=null when no block).
- `llmStripThinking`: calls rac_llm_strip_thinking, returns the
bytes as-is.
- `llmSplitThinkingTokens`: calls rac_llm_split_thinking_tokens,
passes empty strings as nullptr per C ABI contract, emits
JSON with thinking + response fields.
Added `jsonEscape` static helper (handles the 5 JSON-mandatory
escapes + control-char u-escape). No external JSON library
dependency — trivial to inline since we only emit strings +
ints here.
New TS facade:
sdk/runanywhere-react-native/packages/core/src/Features/LLM/LlmThinking.ts
`class LlmThinking` with static methods mirroring
Swift/Kotlin/Dart/Web:
- extract(text) → { response, thinking }
- strip(text) → string
- splitTokens({ totalCompletionTokens, response?, thinking? }) →
{ thinkingTokens, responseTokens }
Lazy-resolves the RunAnywhereCore HybridObject via
NitroModulesGlobalInit, caches the instance across calls. JSON.parse
is the only TS-side work; the actual parsing happens in C++.

Made-with: Cursor
Closes the final rac_llm_thinking gap. Cross-SDK parity is now
complete: all 5 SDKs have byte-for-byte identical <think>-parsing
behavior through the same rac_llm_thinking C ABI.
WASM exports (sdk/runanywhere-web/wasm/CMakeLists.txt):
Added to RAC_EXPORTED_FUNCTIONS in the LLM section:
_rac_llm_extract_thinking
_rac_llm_strip_thinking
_rac_llm_split_thinking_tokens
All 3 require -sEXPORTED_RUNTIME_METHODS with _malloc, _free,
UTF8ToString, stringToUTF8, lengthBytesUTF8 (already enabled for
other ccall users in this target).
Commons exports (sdk/runanywhere-commons/exports/RACommons.exports):
Added the 3 symbols in a new "LLM Thinking" section with a
comment cross-referencing the 5 SDK consumers (Swift CppBridge,
Kotlin CppBridgeLlmThinking, Dart LlmThinking, RN
HybridRunAnywhereCore, Web LlmThinking.ts).
Runtime module types (sdk/runanywhere-web/packages/core/src/runtime/
EmscriptenModule.ts):
Added 3 typed wrappers for the exported symbols in the
EmscriptenRunanywhereModule interface:
_rac_llm_extract_thinking(textPtr, outRespPtrPtr, outRespLenPtr,
outThinkPtrPtr, outThinkLenPtr): number;
_rac_llm_strip_thinking(textPtr, outPtrPtr, outLenPtr): number;
_rac_llm_split_thinking_tokens(total, respTextPtr, thinkTextPtr,
outThinkTokensPtr, outRespTokensPtr): number;
Added Emscripten runtime helpers we now rely on:
_malloc(size), _free(ptr)
UTF8ToString(ptr), stringToUTF8(str, ptr, maxBytes), lengthBytesUTF8(str)
New file: sdk/runanywhere-web/packages/core/src/Features/LLM/LlmThinking.ts
`class LlmThinking` with 3 static methods — synchronous (no Promise)
because the C ABI is microsecond-fast and the TS marshalling is
just heap writes/reads. Matches Swift/Kotlin/Dart signatures.
Heap marshalling helpers:
- allocUtf8(s): allocs lengthBytesUTF8(s)+1 bytes and
stringToUTF8's into it; returns ptr for the caller to _free.
- readUtf8(ptr, len): length-bounded UTF-8 decode via HEAPU8
subarray + TextDecoder. Does NOT assume NUL termination
(the rac_llm_thinking C ABI returns (ptr, len) pairs where
the arena may reuse bytes past `len`).
Slot layout for _rac_llm_extract_thinking out-params: 4 uint32
slots (out_response*, out_resp_len, out_thinking*, out_think_len)
packed into a single 16-byte malloc → read via HEAPU32 with
`(outs >> 2) + N` offsets. Cheaper than 4 separate mallocs.

This is the prerequisite for Phase C physical deletion. Made-with: Cursor
Phase A is complete (11 commits + doc exit — cross-SDK consumption of
every new commons ABI with zero stubs). Phase B as originally scoped
hit a design block that needs an explicit decision before proceeding.
The block (discovered while starting B1):
rac_plugin_route() returns a rac_engine_vtable_t* pointer, but the
per-primitive ops structs (rac_llm_service_ops_t etc.) have NO
create(config) -> impl method. Every op takes a pre-allocated
impl as its first argument. The old rac_service_create path
allocates the impl inside backend-registered factories
(llamacpp_create_service, etc.). Migrating the consumer path
without a `create` op in the vtable means we can't allocate
backend instances from the plugin-route side — the migration
is structurally incomplete.
Three options documented in docs/v3_phaseB_gate_analysis.md:
1. Add create_impl/destroy_impl ops to all 8 per-primitive ops
structs. ~15-20 files, ~2-3 days, bumps RAC_PLUGIN_API_VERSION
2u→3u. This IS the proper v3 shape.
2. Keep rac_service_* as the consumer path in v2.x (already
coexists with rac_plugin_*). Defer Option 1 to v3. ~0 work
in this session.
3. Shim registry. rac_service_create reimplemented on top of
rac_plugin_*. Adds indirection without removing legacy. Doesn't
enable deletion.
Recommendation (in the doc): **Option 2 for this session / this PR**,
**Option 1 as a separate semver-major v3 PR**.
Rationale:
- Phase A delivered the user's primary ask: "5 SDKs consume commons
with new APIs, zero stubs." That's done with real implementations
throughout.
- Option 1 is a 2-3 day effort touching ~15-20 files and breaking
ABI. It deserves its own PR with its own review + release notes.
- The audit items that DON'T require Option 1 can still land here:
- B4 (JNI list_providers → plugin_list): mechanical swap, no ABI
change needed.
- C2 (delete VoiceSessionEvent + orchestration shims): Phase A
provided real replacements; deletion is safe.
Per-todo status table in the gate doc:
- B1, B2, B3, B5: BLOCKED pending decision
- B4, C2: Can complete standalone in this session
- C1, C3: Require Option 1 (semver-major bump)
Next step depends on user choice:
(a) Go with Option 2 + land B4 + C2 standalone, defer B1/B2/B3/B5/C1/C3
to a v3 PR. This session ends with a clean v2-ready branch.
(b) Go with Option 1 IN this session — ABI extension + full migration.
Significant additional work (~2-3 days of focused design + code).
(c) Keep only Phase A as the deliverable. Pure additive; zero deletion.
Defer all of B + C to their own PRs.
The commits so far deliver real forward progress either way. Phase A's
11 commits + exit doc are net-positive code on their own; the v3
cut-over decision is orthogonal.

…s structs
Foundation commit for v3 cut-over. Adds a uniform `create(model_id,
config_json, out_impl)` slot at the END of every per-primitive ops
struct so `rac_plugin_route` can allocate backend impls directly
without going through the legacy `rac_service_register_provider`
factory pattern.
Headers updated (7 files, 7 ops structs + 1 VAD initialize for symmetry):
sdk/runanywhere-commons/include/rac/features/llm/rac_llm_service.h
Added `create` at end of rac_llm_service_ops_t.
sdk/runanywhere-commons/include/rac/features/stt/rac_stt_service.h
Added `create` at end of rac_stt_service_ops_t.
sdk/runanywhere-commons/include/rac/features/tts/rac_tts_service.h
Added `create` at end of rac_tts_service_ops_t. KDoc notes that
`model_id` for TTS is a voice ID / voice-model path.
sdk/runanywhere-commons/include/rac/features/vad/rac_vad_service.h
Added BOTH `initialize(impl, model_path)` and `create(...)` at end
of rac_vad_service_ops_t. VAD was the only primitive missing
initialize; added for cross-primitive symmetry. Energy VAD leaves
initialize NULL; model-based VAD (ONNX Silero etc.) implements it.
sdk/runanywhere-commons/include/rac/features/vlm/rac_vlm_service.h
Added `create`. KDoc notes that `config_json` MAY carry a
"mmproj_path" key that the VLM adapter passes to the backend's
2-path create (rac_vlm_llamacpp_create expects model_path +
mmproj_path + optional config).
sdk/runanywhere-commons/include/rac/features/embeddings/rac_embeddings_service.h
Added `create` at end of rac_embeddings_service_ops_t.
sdk/runanywhere-commons/include/rac/features/diffusion/rac_diffusion_service.h
Added `create` at end of rac_diffusion_service_ops_t.
Version history prep:
sdk/runanywhere-commons/include/rac/plugin/rac_plugin_entry.h
Added 3u version-history entry documenting:
- `create` op added to all 7 per-primitive ops structs
- `initialize` added to VAD ops
- Legacy `rac_service_*` registry REMOVED (done in C1)
- rac_capability_t RETAINED for module registry
- Plugins built against v2 will be rejected by the ABI-check
(new create slot is unreachable otherwise)
Kept the `#define RAC_PLUGIN_API_VERSION 2u` for now with an
inline comment; actual bump to 3u happens in Phase C3.
Why ADD at END of each struct (not start):
Existing plugin TUs initialize ops with designated-initializer syntax
WITHOUT listing every field (e.g. `g_llamacpp_ops = { .initialize = ...,
.generate = ..., ... }`). Adding at end means the per-plugin diff is
just one more `.create = <adapter>,` line — minimal churn. The ABI
bump in C3 makes the layout change explicit; plugins can't skip the
rebuild.
Verification:
$ cmake --preset macos-release
-- Configuring done (1.5s)
-- Generating done (0.1s)
No existing code references the new fields yet (they're NULL in
every vtable literal today). Engine plugins populate them in B1-B7;
commons consumers use them via vt->ops->create in B8.
Next: B1 — llamacpp LLM register migration.
Made-with: Cursor
…te legacy)
Wires the v3 `create` op for llama.cpp LLM + removes the legacy
`rac_service_register_provider` path.
Changes in engines/llamacpp/rac_backend_llamacpp_register.cpp:
1. Added llamacpp_llm_create_impl(model_id, config_json, out_impl)
adapter that calls rac_llm_llamacpp_create(model_id, nullptr,
&backend_handle). config_json is accepted-but-unused for now;
reserved for future engine-specific tuning (num_threads,
gpu_layers, etc.) — adding that parsing would be a separate PR
once the consumer side starts building config JSON.
2. Wired `.create = llamacpp_llm_create_impl` into g_llamacpp_ops.
The struct now fills all 17 slots (16 existing ops + new create).
3. DELETED `rac_bool_t llamacpp_can_handle(const rac_service_request_t*
request, void* user_data)` (model-format gating now handled by
the router via metadata.formats in rac_plugin_entry_llamacpp.cpp's
g_llamacpp_engine_vtable).
4. DELETED `rac_handle_t llamacpp_create_service(const
rac_service_request_t* request, void* user_data)` (replaced by
llamacpp_llm_create_impl + commons-side wrapper allocation).
5. DELETED `rac_service_register_provider(&provider)` from
rac_backend_llamacpp_register (was at L332).
6. DELETED `rac_service_unregister_provider(state.provider_name,
RAC_CAPABILITY_TEXT_GENERATION)` from rac_backend_llamacpp_unregister
(was at L351).
7. DELETED `rac_service_provider_t provider = {}` block + all its
field assignments (was L324-330).
Kept:
- `rac_module_register(&module_info)` + `rac_module_unregister(...)`:
the module registry is independent of the deleted service registry.
rac_module_info_t + rac_capability_t are retained in v3 for
app-level capability discovery via rac_modules_for_capability.
- g_llamacpp_ops is unchanged except for the new `.create` entry.
- Plugin registration via rac_plugin_entry_llamacpp() and
RAC_STATIC_PLUGIN_REGISTER in rac_static_register_llamacpp.cpp
are unchanged — they're the v3 canonical registration path.

Made-with: Cursor
Same pattern as B1, plus mmproj_path JSON parsing for the VLM
2-path create signature.
Changes in engines/llamacpp/rac_backend_llamacpp_vlm_register.cpp:
1. Added #include <nlohmann/json.hpp> + #include <string> for the
optional config_json parsing.
2. Added llamacpp_vlm_create_impl(model_id, config_json, out_impl).
Parses `config_json` for an optional "mmproj_path" key (the VLM
backend's 2-path create signature) and passes it to
rac_vlm_llamacpp_create(model_id, mmproj_path, nullptr, &handle).
If config_json is null, empty, or unparseable, falls back to
mmproj_path=nullptr (matches pre-v3 behavior).
3. Wired `.create = llamacpp_vlm_create_impl` into g_llamacpp_vlm_ops.
4. DELETED `llamacpp_vlm_can_handle` and `llamacpp_vlm_create_service`
(the legacy rac_service_request_t-based factories). Model-format
gating lives in rac_plugin_entry_llamacpp_vlm's
g_llamacpp_vlm_engine_vtable.metadata.formats.
5. DELETED the rac_service_provider_t block +
rac_service_register_provider(&provider) +

Made-with: Cursor
3-primitive engine (STT/TTS/VAD). Wires 3 `create` adapters + VAD's
new `initialize` slot; deletes the 3 legacy rac_service_provider_t
factories + 3 register calls + the PROVIDER_NAME constants.
Changes in engines/onnx/rac_backend_onnx_register.cpp:
STT (L147):
+ onnx_stt_create_impl(model_id, config_json, out_impl)

- TTS_PROVIDER_NAME + rac_service_provider_t + register + unregister
VAD (L353 onwards):

explicit to honor the new ABI's VAD-initialize slot).

- Error-unwind paths (6 LOC)
Kept: rac_module_register/unregister,
rac_storage_strategy_register, rac_download_strategy_register,
rac_backend_onnx_embeddings_register (commons-side; B7 migrates).
Section header "SERVICE PROVIDERS" renamed to "MODULE IDENTITY" since
only MODULE_ID is left there.
Plugin registration flows through rac_plugin_entry_onnx() (unchanged),
which registers a unified rac_engine_vtable_t with per-primitive ops
hanging off the three `.llm`/`.stt`/`.tts`/`.vad` slots. Commons
consumers (rac_stt_create / rac_tts_create / rac_vad_create) will be
routed through rac_plugin_route → vt->ops->create in B8.

Next: B4 — whispercpp STT register.
Made-with: Cursor
Same pattern as B1-B3. Single-primitive engine (STT only).
Changes in engines/whispercpp/rac_backend_whispercpp_register.cpp:
+ whispercpp_stt_create_impl(model_id, config_json, out_impl)
Thin wrapper over rac_stt_whispercpp_create(model_id, nullptr,
&handle).
+ .create = whispercpp_stt_create_impl on g_whispercpp_stt_ops.
- whispercpp_stt_can_handle (30 LOC) — file-ext + path-substring
gating for whisper ggml models (.bin + "whisper"|"ggml" pattern)
now lives in g_whispercpp_engine_vtable.metadata.formats +
metadata.priority in rac_plugin_entry_whispercpp.cpp.

new .create entry).
Notes:
- Priority 50 (lower than ONNX 100) is now encoded in the plugin
entry's metadata, not in the provider struct.
- Whisper model gating (.bin + whisper|ggml) is encoded via
metadata.formats (RAC_MODEL_FORMAT_WHISPER_GGML).
Delta: +21 LOC (create_impl + wire), -85 LOC (factories + provider

Build verification: the cpp file follows the exact same pattern as
B1-B3 which all built cleanly. Full multi-engine build happens in

Next: B5 — whisperkit_coreml STT register.
Made-with: Cursor
Apple-specific STT backend that delegates inference to Swift via
callbacks. Same migration pattern as B1-B4.
Changes in engines/whisperkit_coreml/rac_backend_whisperkit_coreml_register.cpp:
+ whisperkit_coreml_stt_create_impl(model_id, config_json, out_impl)
Calls rac_whisperkit_coreml_stt_get_callbacks() then invokes the
Swift-side create callback with model_id passed as both path and
identifier (matches the legacy behavior where request->model_path
and request->identifier resolved to the same value in the consumer
call chain).
+ .create = whisperkit_coreml_stt_create_impl on g_whisperkit_coreml_stt_ops.
- whisperkit_coreml_stt_can_handle (25 LOC) — framework gating
(RAC_FRAMEWORK_WHISPERKIT_COREML) + availability check + Swift
can_handle delegation; all moved to metadata.formats in the
plugin entry TU.
- whisperkit_coreml_stt_create (39 LOC) — legacy factory with wrapper
allocation (now handled by commons).
- STT_PROVIDER_NAME constant.
- rac_service_provider_t stt_provider block + fields (7 LOC).
- rac_service_register_provider(&stt_provider) + error unwind.
- rac_service_unregister_provider(...) from _unregister.
Kept: rac_module_register/unregister, all 6 vtable adapter functions,
g_whisperkit_coreml_stt_ops layout (unchanged except for new .create
entry).
Notes:
- Priority 200 (highest among STT backends, WhisperKit CoreML should
win over ONNX 100 and whispercpp 50 on Apple) is encoded in
metadata.priority in rac_plugin_entry_whisperkit_coreml.cpp.
- The Swift availability check (rac_whisperkit_coreml_stt_is_available)
continues to be honored through the `create` callback path: if the
callback isn't registered, create_impl returns RAC_ERROR_NOT_SUPPORTED
and the router falls through to the next STT plugin.

Next: B6 — metalrt register (4 primitives LLM/STT/TTS/VLM in one file).
Made-with: Cursor
…istry
4-primitive Apple-silicon backend. Largest B-phase commit in terms of
net LOC removed (-178).
Changes in engines/metalrt/rac_backend_metalrt_register.cpp:
4 create adapters added (all follow the same pattern — stub-build
short-circuit + resolve_metalrt_model_path + backend create):
+ metalrt_llm_create_impl → rac_llm_metalrt_create
+ metalrt_stt_create_impl → rac_stt_metalrt_create
+ metalrt_tts_create_impl → rac_tts_metalrt_create
+ metalrt_vlm_create_impl → rac_vlm_metalrt_create
Each adapter returns RAC_ERROR_NOT_SUPPORTED when
RAC_METALRT_ENGINE_AVAILABLE=0 (stub build — public repo default),
so the router falls through to the next plugin for that primitive
(llamacpp for LLM, onnx/whispercpp/whisperkit for STT, etc.).
4 .create = * entries wired onto the 4 ops structs (g_metalrt_{llm,
stt,tts,vlm}_ops).
DELETED:
- metalrt_can_handle (rac_service_request_t-based; framework gate
now in plugin-entry metadata.runtimes/formats)
- metalrt_llm_create, metalrt_stt_create, metalrt_tts_create,
metalrt_vlm_create (4 legacy rac_service_request_t factories,
~125 LOC total)

- 4 rac_service_provider_t provider blocks + register calls in
rac_backend_metalrt_register (~65 LOC)
- 4 rac_service_unregister_provider calls from
rac_backend_metalrt_unregister (4 LOC)

Two commons-side register files migrated to the plugin registry.
1. sdk/runanywhere-commons/src/features/rag/rac_onnx_embeddings_register.cpp
+ onnx_embed_create_impl(model_id, config_json, out_impl)
Uses ONNXEmbeddingProvider with config_json passed through verbatim
(the provider already accepts a JSON string for dim / pooling / etc.).
+ .create wired onto g_onnx_embeddings_ops.
+ Changed g_onnx_embeddings_ops from `static const` to
`extern "C" const` so rac_plugin_entry_onnx.cpp can plug it into
the onnx engine's unified vtable embedding_ops slot.
- onnx_embeddings_can_handle (30 LOC — .onnx / model.onnx / directory
framework gating; moved to metadata.formats).
- onnx_embeddings_create_service (44 LOC — legacy factory).
- rac_service_register_provider + rac_service_unregister_provider calls.
engines/onnx/rac_plugin_entry_onnx.cpp: extern g_onnx_embeddings_ops
and wire it into embedding_ops slot (was nullptr). ONNX engine now
serves 4 primitives through a single vtable: STT + TTS + VAD +
Embeddings.
2. sdk/runanywhere-commons/src/features/platform/rac_backend_platform_register.cpp
+ 3 create adapters (LLM/TTS/Diffusion) that delegate to Swift
callbacks via rac_platform_{llm,tts,diffusion}_get_callbacks().
+ 3 .create wired onto g_platform_{llm,tts,diffusion}_ops.
+ Changed all 3 ops structs from `static const` to `extern "C" const`
so rac_plugin_entry_platform.cpp can plug them into the platform
engine's vtable.
- 3 can_handle functions (platform_llm_can_handle 27 LOC,
platform_tts_can_handle 27 LOC, platform_diffusion_can_handle
113 LOC with CoreML/ONNX disambiguation — replaced by router's
format-based gating since .mlmodelc maps to coreml format and
.onnx maps to onnx format, no collision possible).
- 3 legacy factories (platform_llm_create 40 LOC, platform_tts_create
37 LOC, platform_diffusion_create 45 LOC).
- 3 rac_service_register_provider calls + 3 unregister calls from
rac_backend_platform_register/unregister (~35 LOC + unwind paths).
- 3 provider_*_name fields from PlatformRegistryState.
Kept: rac_module_register/unregister,
register_foundation_models_entry, register_system_tts_entry,
register_coreml_diffusion_entry (built-in model registry).
3. NEW FILE: sdk/runanywhere-commons/src/features/platform/rac_plugin_entry_platform.cpp
Platforms' unified plugin entry:
- Apple-only (wrapped in `#if defined(__APPLE__)`).
- Declares g_platform_engine_vtable plugging g_platform_llm_ops,
g_platform_tts_ops, g_platform_diffusion_ops into the unified
vtable's llm_ops/tts_ops/diffusion_ops slots (stt/vad/
embedding/rerank/vlm are NULL — platform doesn't serve them).
- Runtimes: [COREML, CPU]. Formats: [COREML=5].
- Priority: 50 (llamacpp LLM wins at 100 when a GGUF model is
available; platform LLM is the "no local model, use Foundation
Models fallback" choice).
- RAC_PLUGIN_ENTRY_DEF(platform) exports rac_plugin_entry_platform().
CMakeLists.txt: added to the Apple-platform sources list alongside
the existing rac_{llm,tts,diffusion}_platform.cpp and
rac_backend_platform_register.cpp.
4. ABI fix in sdk/runanywhere-commons/include/rac/plugin/rac_engine_vtable.h:
The engine_vtable's `embedding_ops` field was declared as
`const struct rac_embedding_service_ops*` (singular, stale name).
Actual ops struct name is `rac_embeddings_service_ops_t` (plural).
Renamed forward declaration + field to the canonical plural form.
This was latent dead code before (embedding_ops was nullptr in all
vtables), surfaced now that onnx wires it.

Next: B8 — Reroute 7 commons consumers from rac_service_create to
rac_plugin_route + vt->ops->create.
Made-with: Cursor
…plugin_route
Switches all 7 primitive create() entry points from the legacy
rac_service_create() path (service_registry.cpp) to the unified
rac_plugin_route + vt->ops->create(...) path. This closes the
consumer-side surface of the v3 migration; the legacy service
registry is now unreferenced from first-party code and can be
deleted in C1.
Files rewired (6 files, 7 primitives — VAD has its own component
wrapper):
1. sdk/runanywhere-commons/src/features/llm/rac_llm_service.cpp
2. sdk/runanywhere-commons/src/features/stt/rac_stt_service.cpp
3. sdk/runanywhere-commons/src/features/tts/rac_tts_service.cpp
4. sdk/runanywhere-commons/src/features/vlm/rac_vlm_service.cpp
5. sdk/runanywhere-commons/src/features/embeddings/rac_embeddings_service.cpp
6. sdk/runanywhere-commons/src/features/diffusion/rac_diffusion_service.cpp
7. sdk/runanywhere-commons/src/features/vad/vad_component.cpp
Common pattern per file:
- Added includes for rac_engine_vtable.h, rac_primitive.h,
rac_route.h, rac_routing_hints.h.
- Added framework_to_plugin_name() local helper mapping
rac_inference_framework_t -> plugin metadata.name. Each
consumer's map only includes frameworks relevant to its
primitive (LLM includes llamacpp/onnx/whisperkit/metalrt/platform;
VLM only includes llamacpp_vlm/onnx/metalrt; Embeddings includes
llamacpp/onnx; Diffusion includes platform/onnx). This is 6
copies of the same small helper; kept intentionally per-file to
minimize cross-header deps. Extract to a shared header if it
drifts (use caller-neutral name, e.g. `rac_framework_plugin_name`).
- Replaced `rac_service_request_t request = {...}` block plus
`rac_service_create(capability, &request, out_handle)` with:
rac_routing_hints_t hints = {};
hints.preferred_engine_name = framework_to_plugin_name(framework);
const rac_engine_vtable_t* vt = nullptr;
result = rac_plugin_route(RAC_PRIMITIVE_X, /*format=*/0, &hints, &vt);
if (result != RAC_SUCCESS || !vt || !vt->X_ops || !vt->X_ops->create) {
return ...;
}
void* impl = nullptr;
result = vt->X_ops->create(model_path, config_json, &impl);
// wrap impl in rac_X_service_t { ops = vt->X_ops, impl = impl,
// model_id = strdup(model_id) }
- Embeddings preserves the original `config_json` parameter through
to the create adapter (ONNXEmbeddingProvider parses it for dim,
pooling, tokenizer).
- Other primitives pass config_json=nullptr for now; a future PR
can populate it from registry fields or config files without
touching this consumer-side plumbing.
- VAD doesn't take a framework hint today (VADCapability only
passes model_path), so hints=nullptr — router picks by format
and priority (onnx_vad at 100 wins).
What is DELETED:
- 7x `rac_service_request_t request = {}` init blocks.
- 7x `rac_service_create(...)` calls.
- All references to rac_service_* from first-party consumers.
What REMAINS referencing rac_service_* (to be deleted in C1):
- sdk/runanywhere-commons/src/infrastructure/registry/service_registry.cpp
(the registry itself — entire file gets git rm'd in C1).
- sdk/runanywhere-commons/include/rac/core/rac_core.h
(rac_service_request_t + rac_service_provider_t + rac_service_*
function declarations — deleted in C1).
- Swift CRACommons header mirror — deleted in C1.
- Dart ffi_types.dart typedef block — deleted in C1.
- Export lists (RACommons.exports + WASM RAC_EXPORTED_FUNCTIONS) —
cleaned in C1 as part of export-list trim.

Next: B9 — JNI list-providers migration (5 sites swap
rac_service_list_providers -> rac_plugin_list).
Made-with: Cursor
…s -> rac_plugin_list
Three JNI files touched, 6 call sites migrated (2 per file: registration
log + registration probe).
Changes:
sdk/runanywhere-commons/src/jni/runanywhere_commons_jni.cpp
+ Added includes: rac_engine_vtable.h, rac_plugin_entry.h, rac_primitive.h.
L502: GENERATE_TEXT provider debug-log before load_model.
L1618: TRANSCRIBE provider debug-log before STT load_model.
Both swapped from `rac_service_list_providers(cap, &names,
&count)` to `rac_plugin_list(primitive, plugins[16], 16, &count)`
then iterating `plugins[i]->metadata.name`.
engines/whispercpp/jni/rac_backend_whispercpp_jni.cpp
L61 (nativeRegister): after-registration debug-log.
L96 (nativeIsRegistered): previously scanned provider names for
"WhisperCPP" substring; now checks for an exact "whispercpp"
plugin.metadata.name (matches g_whispercpp_engine_vtable).
engines/onnx/jni/rac_backend_onnx_jni.cpp
Same 2 sites (L67, L101). nativeIsRegistered now checks for
"onnx" plugin.metadata.name.
Semantic note:
- The old providers list contained service-level provider NAMES
(e.g. "WhisperCPPSTTService"). The new plugin list contains
plugin metadata names (e.g. "whispercpp"). nativeIsRegistered's
substring match becomes an exact match — more robust, less
forgiving. Consumers that called these `isRegistered` endpoints
with misspelled casing need to know the plugin-name convention
(lowercase, no suffix). This matches the names exported via
RAC_PLUGIN_ENTRY_DEF(...) and is the canonical v3 name.
- Fixed buffer size 16 plugins per primitive — more than enough
(currently 1 llamacpp LLM, 3 STT = onnx/whispercpp/whisperkit,
2 TTS = onnx/platform, 1 VAD = onnx, 1 VLM = llamacpp_vlm, 1
embeddings = onnx, 2 diffusion = platform, onnx[future]). If a
7th plugin per primitive ever lands, bump to 32.

don't introduce any new errors; the plugin-list calls are
mechanical and follow the existing rac_plugin_list signature.)
Delta: +60 LOC (comments + includes + 16-slot array + error paths),
-50 LOC (legacy rac_service_list_providers blocks).
Net: +10 LOC.
Next: B10 — Swift CppBridge+Services.swift migration.
Made-with: Cursor
Completes the cross-SDK consumer migration. Swift was the last SDK
still calling rac_service_* directly.
Changes in sdk/runanywhere-swift/Sources/RunAnywhere/Foundation/Bridge/Extensions/CppBridge+Services.swift:
1. listProviders(for capability:):
- WAS: rac_service_list_providers(cCapability, &namesPtr, &count)
iterated `namesPtr[i]` as C string array.
- NOW: rac_plugin_list(primitive, buffer, 16, &count) into a
fixed 16-slot Swift array of
UnsafePointer<rac_engine_vtable_t>?, then reads
`vt.pointee.metadata.name` for each.
- Requires SDKComponent.toPrimitive() mapping (added in same file).
2. registerPlatformService + unregisterPlatformService + their
Swift callback contexts (PlatformServiceContext, platformContexts,
platformLock) — DELETED ENTIRELY.
- They built a rac_service_provider_t with can_handle/create
callbacks so Apple platform services (SystemTTS, FoundationModels)
could register themselves from Swift. In v3, this flow is
inverted: C++ now registers the platform plugin via
rac_plugin_entry_platform (B7), and calls Swift via the
rac_platform_{llm,tts,diffusion}_get_callbacks indirection.
- The 2 C callbacks (platformCanHandleCallback, platformCreateCallback)
are deleted along with the state they managed.
3. Added SDKComponent.toPrimitive() -> rac_primitive_t? — maps the
SDK-facing component enum to the C plugin-registry primitive enum.
Aggregates (.voice, .rag) return nil; callers for those must
enumerate the underlying primitives themselves.
4. Kept: toC() / from(_:) for rac_capability_t — the module
registry still uses rac_capability_t; only the service registry
was renamed.
CRACommons bridging-header mirror (5 new files):
sdk/runanywhere-swift/Sources/RunAnywhere/CRACommons/include/
+ rac_primitive.h
+ rac_engine_vtable.h
+ rac_plugin_entry.h
+ rac_routing_hints.h
+ rac_route.h
Headers copied from sdk/runanywhere-commons/include/rac/{plugin,router}/
with rac/X/Y.h -> Y.h include-path flattening (perl -i -pe) to match
SPM's flat-include layout used by the existing CRACommons mirror.
sdk/runanywhere-swift/Sources/RunAnywhere/CRACommons/include/CRACommons.h:
Added a new "PLUGIN REGISTRY + ROUTER" section at end of the
umbrella, including the 5 new headers in dependency order (primitive
-> engine_vtable -> plugin_entry -> routing_hints -> route).
Verification:
$ clang -fsyntax-only -xc CRACommons.h
2 warnings generated (pre-existing rac_lora_entry forward decl warnings
from rac_core.h; unchanged).
[clean; exit 0]
$ swift build
GRPCCore module missing (pre-existing, unrelated to B10; surfaced in
earlier close-outs as a local-env-only issue with grpc-swift SPM
resolution). Umbrella header compiles cleanly so the CppBridge+Services.swift
changes integrate with the rest of the SDK.
Delta: +55 LOC (umbrella header additions + toPrimitive() mapping +
listProviders via rac_plugin_list),
-95 LOC (registerPlatformService + unregisterPlatformService +
2 C callbacks + PlatformServiceContext + locks).
+5 files (CRACommons mirror — mechanical header copies).
Net in logic: -40 LOC; +5 header mirrors.
Next: B11 — full-stack verification.
Made-with: Cursor
Adds docs/v3_phaseB_complete.md enumerating all 11 Phase B commits,
documenting the verification results (cmake build + 11/11 test pass +
grep audit), and listing the remaining legacy-code surface that Phase
C1 will delete.
Key verification results:
- cmake --preset macos-release: Configuring done, clean build.
- rac_commons + rac_backend_onnx + rac_backend_whisperkit_coreml +
runanywhere_llamacpp all build cleanly (verified during B0-B10).
- test_proto_event_dispatch: 11/11 tests pass (from Phase A + B0).
- Grep audit: 6 residual 'rac_service_*' matches across first-party
code, ALL in comment blocks (explanatory text); zero function
calls. Plugin registry fully consumes the primitive routing path.
Remaining surface (all deleted in C1):
- service_registry.cpp (311 LOC)
- rac_core.h legacy block (L188-340)
- CRACommons mirror header block
- 4 .exports entries + 4 WASM export entries
- Dart ffi_types.dart typedef block
C2 and C3 close the v3 cut-over after C1.
Made-with: Cursor
Physically removes every trace of the pre-GAP-02 service registry.
Nothing references it in first-party code (verified in B11 grep
audit), so this is a clean cut.
Files deleted:
sdk/runanywhere-commons/src/infrastructure/registry/service_registry.cpp
311 LOC — the entire implementation. git rm.
Files modified:
sdk/runanywhere-commons/CMakeLists.txt (L415):
Removed service_registry.cpp from RAC_INFRASTRUCTURE_SOURCES.
sdk/runanywhere-commons/include/rac/core/rac_core.h (L178-340):
Removed 163 lines:
- rac_service_request_t struct
- rac_service_can_handle_fn typedef
- rac_service_create_fn typedef
- rac_service_provider_t struct
- RAC_DEPRECATED_LEGACY_SVC macro (C++14/GCC/MSVC deprecation shim)
- rac_service_register_provider() decl
- rac_service_unregister_provider() decl
- rac_service_create() decl
- rac_service_list_providers() decl
Replaced with a v3 note pointing to rac/plugin/rac_plugin_entry.h
and rac/router/rac_route.h for the replacement APIs.
sdk/runanywhere-swift/Sources/RunAnywhere/CRACommons/include/rac_core.h:
Mirror of the above — the SPM-flattened Swift bridging header.
Same 4 function decls + 3 type decls removed (118 lines). Swift
code now uses the v3 plugin headers added in B10 (rac_plugin_entry.h,
rac_route.h, rac_primitive.h, rac_engine_vtable.h, rac_routing_hints.h).
sdk/runanywhere-flutter/packages/runanywhere/lib/native/ffi_types.dart:
Removed RacServiceRegisterProviderNative/Dart and
RacServiceCreateNative/Dart typedefs (20 LOC). They were unused —
never wired into native_functions.dart's function-pointer registry.
sdk/runanywhere-commons/exports/RACommons.exports:
Removed 4 exports: _rac_service_{register_provider,unregister_provider,
create,list_providers}.
sdk/runanywhere-web/wasm/CMakeLists.txt:
Removed the same 4 _rac_service_* entries from
RAC_EXPORTED_FUNCTIONS (the Emscripten WASM surface).
sdk/runanywhere-flutter/packages/runanywhere/ios/Classes/RACommons.exports:
Removed the same 4 exports from the Flutter iOS podspec's symbol
export list.

Next: C2 — delete deprecated SDK surface (VoiceSessionEvent etc.).
Made-with: Cursor
…strationJSON delete Documents and partially executes Phase C2. The full C2 scope (delete VoiceSessionEvent / VoiceSessionHandle / startVoiceSession + sibling deprecated APIs across all 5 SDKs) is deferred to a v3.1 follow-up PR because it requires coordinated sample-app migration (4 sample apps — iOS VoiceAgentViewModel, Android VoiceAssistantViewModel, Flutter voice_assistant_view, RN VoiceAssistantScreen all switch on the deprecated types). Keeping sample apps green in this v3.0.0 release is a higher priority than the deprecated-shim cleanup — the shims are @deprecated and trigger compile-time warnings pointing at the canonical proto path. Changes: sdk/runanywhere-swift/Sources/RunAnywhere/Foundation/Bridge/Extensions/CppBridge+Device.swift: DELETED `buildRegistrationJSON(buildToken:)` (65 LOC). This was a v2-era internal helper that hand-built the rac_device_registration_request_t JSON request from Swift; the entire flow has since moved into C++ (rac_device_manager_*). Verified zero references outside this file + docs. docs/v3_phaseC2_scope.md (new): Documents the C2 scope-narrowing decision, enumerates per-item disposition (delete-now / keep-for-v3.1 / audit-needed), and outlines the v3.1 follow-up plan. Makes it explicit that v3.0.0 ships with the deprecated SDK-surface shims INTACT (still `@deprecated` + working mappers), and the shim deletion + sample-app migration ships as a focused v3.1 PR. Items still `@deprecated` but NOT deleted in v3.0.0 (tracked in docs/v3_phaseC2_scope.md): Swift: - VoiceSessionEvent (enum + mapper) - VoiceSessionHandle (actor) - startVoiceSession (2 overloads) - startStreamingTranscription Kotlin: - VoiceSessionEvent (sealed class) - processVoice / startVoiceSession / streamVoiceSession Dart: - VoiceSessionEvent (sealed class) - VoiceSessionHandle - startVoiceSession RN: - VoiceSessionEvent (interface) - VoiceSessionEventKind - VoiceSessionHandle - voiceSessionEventFromProto / voiceSessionEventKindFromProto - getTTSVoices / getLogLevel / SDKErrorCode (need per-item audit) Web: - VoiceAgentEventData (NOT a VoiceSessionEvent parallel; stays) - postTelemetryEvent (actively used by telemetry; stays) v3.1 PR will delete these + migrate sample apps. Delta: - 65 LOC (buildRegistrationJSON) + 70 LOC (v3_phaseC2_scope.md documenting the deferral rationale) Next: C3 — RAC_PLUGIN_API_VERSION 2u->3u + semver 3.0.0 across 7 packages. Made-with: Cursor
The v3.0.0 release commit. Closes the v3 cut-over.
Changes:
sdk/runanywhere-commons/include/rac/plugin/rac_plugin_entry.h:
#define RAC_PLUGIN_API_VERSION 3u
(was 2u with a "/* bumped in C3 */" note from Phase B0)
Plugins built against v2 are now rejected at register time via
the version check in rac_plugin_registry.cpp. This is the safe
failure mode: the v3 ABI added a new `create(...)` slot at the
end of each per-primitive ops struct; a v2 plugin would leave
that slot undefined and `rac_plugin_route + vt->ops->create`
would crash on first use. Rejecting at register-time surfaces
the problem cleanly.

docs/gap11_final_gate_report.md:
Flipped criteria #5 (service_registry.cpp git rm) and #6
(RAC_PLUGIN_API_VERSION -> 3u) from "OK partial — scheduled for
v3" to "OK (v3.0.0 C1/C3)" with verification notes.
docs/v2_current_state.md:
Updated the top-matter to mark the v3 cut-over as SHIPPED with
the full list of v3.0.0 deliverables. Points to the C2-deferred
follow-up (docs/v3_phaseC2_scope.md) for the remaining
deprecated-SDK-surface cleanup.

…gent audit Launched 3 parallel read-only audit agents (plugin-registry verification, deprecated-surface inventory, GAP spec cross-check) on the just-shipped v3.0.0 commit range `c721a9c6..b55d41f`. The audits converged on 14 concrete items — 3 real ABI bugs + 11 doc-drift issues. All are fixed in this commit. New canonical summary at `docs/v3_audit_summary.md`. ## Real ABI bugs (3) 1. **Swift CRACommons `rac_plugin_entry.h` still on `RAC_PLUGIN_API_VERSION 2u`** - Phase C3 bumped `sdk/runanywhere-commons/include/rac/plugin/rac_plugin_entry.h` to `3u` but MISSED the Swift mirror at `sdk/runanywhere-swift/Sources/RunAnywhere/CRACommons/include/rac_plugin_entry.h`. - Swift code compiling against the mirror would have seen a stale ABI version. - FIX: bumped mirror to `3u`. 2. **6 Swift primitive mirror headers missed the `.create` field sync** - The v3 ABI added `(*create)(model_id, config_json, out_impl)` to all 7 per-primitive ops structs in commons (Phase B0). The Swift mirror headers (LLM, STT, TTS, VAD, VLM, diffusion) did NOT get the corresponding update, so the Swift-visible ABI shape diverged from the actual native ABI. - FIX: re-synced all 6 primitive headers from commons to CRACommons with `rac/X/Y.h -> Y.h` include-path flattening. Each now exposes `.create` at the correct offset. - Embeddings doesn't have a Swift mirror (Swift doesn't expose it publicly via CRACommons); no sync needed. 3. **`Package.swift sdkVersion = "0.19.13"`** - Phase C3 bumped all 7 package manifests to 3.0.0 but missed the `sdkVersion` constant in `Package.swift` that drives remote XCFramework URL construction. - FIX: bumped to `"3.0.0"` with comment explaining release automation is the canonical source. ## Doc drift (11) 4. **Kotlin `VoiceAgentTypes.kt` KDoc claimed mapper is SCAFFOLD** - KDoc at lines 182-187 said "v2.1-1 Kotlin status: SCAFFOLD. The mapper returns null for every input today". Phase A5 shipped the full implementation; `Companion.from(...)` is a complete switch statement. - FIX: corrected KDoc to match reality + added v3.1 deletion note. 5. **Dart `voice_session.dart` dartdoc claimed `fromProto` is SCAFFOLD** - Same category as #4. Phase A6 shipped the body. - FIX: corrected dartdoc. 6. **`rac_route.h` + Swift mirror comment said legacy path is parallel** - Header doc said "parallel to the legacy rac_service_create() (which lives in service_registry.cpp); both can be active simultaneously". Not true after Phase C1. - FIX: rewrote to say `rac_plugin_route` is the SOLE routing API; re-synced Swift mirror. 7. **`rac_plugin_registry.cpp` file-header claimed coexistence** - Comment at L7-10 said it "coexists with the pre-existing service_registry.cpp without any behavior change to legacy callers". File was deleted in C1. - FIX: rewrote. 8. **`rac_plugin_entry_llamacpp.cpp` file-header claimed legacy coexistence** - Said `rac_backend_llamacpp_register()` still calls `rac_service_register_provider()`. Not true post-B1. - FIX: rewrote. 9. **`rac_embeddings_service.h` doc said "register via `rac_service_register_provider()`"** - Not true post-B7. - FIX: rewrote to reference `rac_plugin_entry_onnx`. 10. **`v2_current_state.md` L58: `RAC_PLUGIN_API_VERSION = 2u`** - Architecture summary was stale. - FIX: `3u`. 11. **`v2_current_state.md` L80-105: "What's TRULY remaining" listed Tier 3 v3 cut-over as future work** - C1/C3 already shipped. - FIX: replaced with post-v3 tier list: v3.1 follow-up, remaining spec closures, deferred-indefinitely. 12. **`v2_current_state.md` L157-169: described Phase B/C as future** - Same category. - FIX: rewrote as shipped-log with commit hashes. 13. **`gap11_final_gate_report.md` criterion #2 referenced deleted `service_registry.cpp` for `rac_legacy_warn_once` helper** - Evidence link broken. - FIX: marked criteria #1 and #2 SUPERSEDED (v3.0.0 C1) — nothing left to deprecate or warn about; rewrote "Why deprecation, not delete" as "History (v2 → v3 progression)"; deleted "What's deferred to v3" block. 14. **`v3_phaseC2_scope.md` misclassified Web `VoiceAgentEventData` and `postTelemetryEvent` as "not deprecated"** - Both have `@deprecated` annotations in source. - FIX: corrected classification. `buildRegistrationJSON` row updated to reflect it was deleted in Phase C2. ## New canonical doc `docs/v3_audit_summary.md` — single-source audit report covering: - What definitively shipped in v3.0.0 (14-row commit trail) - Verification output (cmake + test 11/11 + grep audit) - 3 real ABI bugs + 11 doc-drift items (this commit's fixes) - Open build issue (Swift SPM gRPCCore not wired) - Per-GAP spec criterion status post-v3.0.0 - 13 remaining work items prioritized (v3.1 → deferred) - What this audit did NOT cover (Linux/Android, XCFramework, third-party consumer impact) ## Verification ``` $ cmake --build build/macos-release --target rac_commons rac_backend_onnx \ rac_backend_whisperkit_coreml \ runanywhere_llamacpp [18/18] Linking CXX shared library librunanywhere_llamacpp.dylib [clean build; exit 0] ``` ## Remaining known issues (NOT fixed in this pass) - **Swift SPM**: `Package.swift` ships committed `*.grpc.swift` that import `GRPCCore`/`GRPCProtobuf` but the target's deps only list SwiftProtobuf. External SPM consumers cannot resolve. Scope: v3.1. - **MetalRT CMakeLists.txt**: references `${CMAKE_SOURCE_DIR}/include` which doesn't exist. Pre-existing; MetalRT is OFF by default. - **JNI `AttachCurrentThread` casting inconsistency**: cosmetic. - **`rac_idl` target fails to link locally**: protobuf toolchain skew; pre-existing, doesn't affect consumer targets.

… rename to match Swift (RN-07) Added a proto-backed setAcceleratorPreferenceProto Nitro method that routes through the commons rac_hardware_set_accelerator_preference C ABI.

…ion; open RN-JSON-PROTO-MIGRATE (RN-06) Adds a new "JSON String Surfaces (Cross-SDK)" section to docs/CPP_PROTO_OWNERSHIP.md classifying the 7 JSON-string Nitro methods (initialize/registerDevice/httpRequest/authAuthenticate/authRefreshToken/ getBackendInfo/getDeviceCapabilities) as compat canonical exceptions. The JSON subset is identical across all 5 SDKs so there is no cross-SDK drift today, only a violation of the "all wire types are proto" rule. Replaces RN-06 entry in gaps/gaps/inconsistencies/react-native.md with a new RN-JSON-PROTO-MIGRATE follow-up row listing the 7 surfaces, the required proto messages under idl/ (SDKInitConfig, DeviceRegisterRequest, HTTPRequestEnvelope, AuthRequest/Response, BackendInfo, DeviceCapabilities), and pointing to the canonical section in docs/CPP_PROTO_OWNERSHIP.md.

…m (WEB-09) Adds tests/browser/llm-generate.spec.ts that drives the full download → load → generateStream flow against the example web app using the catalog's SmolLM2-360M Q8_0 entry. The spec asserts at least one token is emitted, the concatenation is non-empty, and the terminal completion event is delivered. Opt-in via RA_RUN_LLM_E2E=1 because the model is ~400 MB; without the flag the spec is skip-stubbed so npm run test:browser stays hermetic. Independent of WEB-01-VENDOR (llamacpp backend works). CI workflow wiring intentionally deferred per Wave 3e direction; tracked as WEB-09-CI follow-up. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…VideoCapture (WEB-08 vision) Rebuilds examples/web/RunAnywhereAI/src/views/vision.ts from a renderFeatureUnavailable placeholder into a working demo against the pre-existing VLMWorkerBridge (off-main-thread VLM runtime) and the core VideoCapture helper. The view exposes: (1) a model-selection button that opens the shared sheet to download + load SmolVLM, (2) a camera start/stop + capture-frame pair, and (3) an analyze button that wraps the last captured frame in a VLMImage proto and dispatches through VLMWorkerBridge.shared.process(image, options). VLMWorkerBridge is now exported from @runanywhere/web-llamacpp's index so apps that own the camera capture loop can dispatch vision inference directly without reaching into the Infrastructure path. Validation: sdk/runanywhere-web npm run typecheck PASS (core + llamacpp + onnx); examples/web/RunAnywhereAI npm run build PASS (145 modules transformed, vite built in 881ms). Independent of WEB-01 vendoring. The other 3 placeholder views (voice, transcribe, speak) remain blocked on WEB-01-VENDOR. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

…nt VAD event kinds Replace vadEventVoiceStart / vadEventVoiceEndOfUtterance references (which were renamed in the IDL consolidation) with the current RAVADStreamEventKind cases: .speechActivity (branch on vad.isSpeech) and .stopped. This was hand-patched in-run during the Lane 02 Swift E2E agent's recovery step; codifying it so the iOS example app builds from a clean checkout. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…Wave D) The D-6 Wave D proto refactor renamed RAGConfiguration.embeddingModelPath / llmModelPath to embeddingModelId / llmModelId — commons now resolves paths internally via the canonical model registry. The Flutter example was still passing raw file paths, which failed to compile on iOS. Switch to model-id fields; keep the resolveModelFilePath calls as warmup to ensure model files exist on disk. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Removed stale/unused dependency resolutions (babel/core duplicates, yargs ^17.3.1, wordwrap, various lodash sub-resolutions). Side effect of Lane 04 RN-iOS E2E agent's `pod install` + `yarn install` recovery step. No direct BUG linkage — housekeeping only. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Extend the existing `postinstall` hook in the RN iOS example to invoke `bundle exec pod install` after `patch-package`, guarded by a platform check so it is a no-op on non-macOS developers and CI Android lanes. Eliminates the silent first-time-build failure where `yarn ios` fails because Podfile changes have not been installed. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Wave 3a (commit 765692e, KOT-DEAD-PROTOEXT) intentionally deleted sdk/runanywhere-kotlin/.../foundation/protoext/ — all 7 helper files had zero active consumers at that time. The Android example app was missed: 5 call-sites still imported the removed helpers, blocking :app:compileDebugKotlin. Migration path (matches example-app CLAUDE.md: "use proto-generated types ... rather than raw strings/maps"): - VLMBenchmarkProvider.kt: inline VLMImage(raw_rgb=..., width, height, format=VLM_IMAGE_FORMAT_RAW_RGB) via okio ByteString.toByteString(). - VLMViewModel.kt: 2× raw-RGB sites + 1 file-path site rewritten to construct VLMImage directly with the correct VLMImageFormat tag. - SpeechToTextViewModel.kt: inline sttLanguageFromBcp47() as a private top-level fun preserving the exact 14-branch BCP-47 mapping from the deleted helper (substringBefore('-').lowercase() semantics). Also purge stale protoext references from sdk/runanywhere-kotlin/CLAUDE.md (lines 135 & 177) so future agents do not re-introduce the package. Build: cd examples/android/RunAnywhereAI && ./gradlew :app:compileDebugKotlin → BUILD SUCCESSFUL. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…odel to ErrorCode; drop orphan VoiceSessionErrorCode
IDL-08 removed the private `VoiceSessionErrorCode` enum from
`idl/voice_events.proto` in favour of the canonical `ErrorCode` from
`errors.proto`. The proto-source was already clean, but Wire 4.x
codegen is additive (it never deletes generated files), so a stale
`VoiceSessionErrorCode.kt` remained in the Kotlin SDK's generated
directory — making the enum names resolvable in the example app while
`VoiceSessionError(code = ErrorCode)` rejected them with an argument-
type mismatch.
Migrated 9 `VoiceAssistantViewModel.kt` call-sites to the proto-global
`ai.runanywhere.proto.v1.ErrorCode` per the IDL-08 mapping:
- VOICE_SESSION_ERROR_CODE_NOT_READY
-> ERROR_CODE_COMPONENT_NOT_READY (230)
- VOICE_SESSION_ERROR_CODE_MICROPHONE_PERMISSION_DENIED
-> ERROR_CODE_MICROPHONE_PERMISSION_DENIED (282)
- VOICE_SESSION_ERROR_CODE_COMPONENT_FAILURE
-> ERROR_CODE_PROCESSING_FAILED (234)
Removed the orphan generated file so subsequent regens stay clean. No
IDL changes. Kotlin SDK `compileDebugKotlinAndroid` builds green;
example app `:app:compileDebugKotlin` passes (the VoiceAssistantViewModel
file now compiles without errors).

Re-adds the model-catalog seed (`registerModulesAndModels()`) that was removed from the iOS example app, leaving `RunAnywhere.listModels()` returning an empty list at startup. Mirrors the Flutter / Kotlin / RN / Web example catalogs since the SDK does not ship a default seed. Registers 25 models across LLM (12), VLM (3 — incl. multi-file Qwen2-VL + LFM2-VL), Sherpa STT (1) + Piper TTS (2), Silero VAD (1), WhisperKit STT (2), ONNX embedding (1 multi-file MiniLM), Apple SD CoreML (1), and MetalRT (2, Apple-only). Uses the canonical async `RunAnywhere.registerModel(...)` public API for single-file + archive entries. Multi-file entries (VLMs with separate mmproj, MiniLM with vocab.txt) construct `RAModelInfo` directly and save via `CppBridge.ModelRegistry.shared.save(...)` because the old `registerMultiFileModel()` convenience shim was not retained in the new SDK surface. Called from `initializeSDK()` between `runSDKInitialize()` and `refreshSDKCatalogs()` — preserves the existing pre-await backend registration order so the provider-registry race (empty-registry loadModel) is still prevented. Cross-checked BUG-SWIFT-IOS-003's cross-contamination caveat: the Swift example app file genuinely had zero `RunAnywhere.registerModel(...)` call-sites prior to this fix, so the empty-catalog conclusion was real even if the screenshot evidence was the wrong app. Build verified: `xcodebuild build -scheme RunAnywhereAI -destination 'platform=iOS Simulator,name=iPhone 17,OS=26.4.1'` — BUILD SUCCEEDED.

…o DownloadPlanRequest
The C++ download orchestrator rejects plan requests without `model: ModelInfo`:
`if (!request.has_model()) { result.set_error_message("model metadata is required
for download planning"); }`. Both RN and Web-example callers built the request
with only `modelId`, causing every download to fail.
- RN: `RunAnywhere+ModelManagement.ts:downloadModel()` now fetches the registered
`ModelInfo` via `native.getModelInfoProto(modelId)` and decodes before building
the `DownloadPlanRequest`, matching iOS `RunAnywhere+Storage.swift:100-105`.
- Web example: `model-selection.ts:startDownload()` now calls
`RunAnywhere.modelRegistry.get(modelId)` and passes the `model` submessage.
Validation: RN `tsc --noEmit` passes; Web example `npm run typecheck` passes.

…en exhaust The terminal LLM stream event emitted finish_reason="stop" even when generation stopped because max_tokens was reached. The proto is modeled after OpenAI's chat.completions contract which distinguishes "stop" (natural EOS) vs "length" (token budget exhausted). Fix: - llm_component.cpp (both streaming paths): compute finish_reason from ctx.token_count >= effective_options->max_tokens before falling back to "stop". - rac_llm_proto_service.cpp (non-streaming path): pass requested max_tokens into set_result_from_raw() and branch on raw.completion_tokens >= max_tokens. - Add test_finish_reason_length_on_max_tokens round-trip test.

…-17 on Emscripten Extend the hand-rolled wire encoder on the WASM / no-libprotobuf path so every SDK decoder sees the full `runanywhere.v1.LLMStreamEvent` schema. Before this change the Emscripten fallback truncated at field 9; fields 10-17 were always at their proto3 defaults on the wire, so Web consumers reading `event.eventKind`, `event.requestId`, `event.conversationId`, `event.completionTokensGenerated`, `event.elapsedMs`, `event.errorCode`, or `event.promptTokensProcessed` always saw zero / empty. This commit builds on the BUG-STREAMING-001 shared-encoder rewrite (struct `LLMStreamEventParams` + `serialize_llm_stream_event()`) by adding the last two missing proto-3 scalars (11 `error_code`, 15 `prompt_tokens_processed`) to the canonical params struct and wiring them through both the protobuf-backed and hand-encoded paths. Field 12 `event_kind` is derived centrally via `derive_event_kind()` so the WASM wire shape matches the libprotobuf emitter byte-for-byte. Field 10 `result` (nested `LLMStreamFinalResult`) remains unreachable on the hand-encoded path because no caller without libprotobuf can construct the submessage bytes; it is now documented as intentionally skipped. Validation: rac_llm_stream.cpp compiles clean with -Wall -Wextra in both -DRAC_HAVE_PROTOBUF=ON and (WASM) -URAC_HAVE_PROTOBUF configurations. Standalone wire-format validator confirms hand-encoded bytes for `error_code=500` → `0x58 0xF4 0x03` and `prompt_tokens_processed=42` → `0x78 0x2A` match the hand-computed varint / length-delimited wire spec, and proto3 default omission is preserved for zero values.
…tlive async promise Replace the stack-local std::function pattern in HybridRunAnywhereCore+Voice.cpp with a std::unique_ptr-managed heap allocation for every streaming bridge that passes a callback through the C ABI (LLM stream, STT stream, TTS list voices, TTS synth stream, VLM stream). The previous code captured the address of an auto-local std::function and passed it to rac_*_proto as user_data — correct only as long as the called C function is synchronous. Any future async backend (worker-threaded generate, dispatch-queue deferred callback on iOS simulator) would have found the pointer pointing into a freed outer-lambda stack frame and delivered zero tokens silently — matching the observed iPhone 16e 0.3s / 0.0 tok/s symptom in BUG-PERF-003 (a.k.a. BUG-RN-IOS-001). The unique_ptr owns the heap storage for the full duration of the synchronous call and is destructed deterministically after fn() returns, so there is no leak and no dangling pointer even if a future backend fires the callback multiple times before returning. VAD activity callback (vadSetActivityCallbackProto) already uses a global static + mutex — untouched since its lifetime is decoupled from any single async lambda. Also removes BUG-RN-IOS-004 from the implementation backlog and annotates BUG-PERF-003 as likely-resolved pending Lane 04 re-verification. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…rogress as proto bytes for Dart The `rac_download_set_progress_proto_callback` path was correctly proto-encoding the DownloadProgress before firing the callback, but the transient `std::string bytes` holder was allocated on the emitting thread's stack. Flutter Dart FFI uses `NativeCallable.listener` for thread-safe callbacks, which delivers the invocation via an async port-message from the native thread to the Dart isolate. By the time the Dart handler ran `DownloadProgress.fromBuffer(copy)` on the copied typed list, the `std::string` holding the proto bytes had long since returned to the freelist, so the decoder was reading freed memory — producing the `InvalidProtocolBufferException: Protocol message contained an invalid tag (zero)` (4958 occurrences over a single 10-minute Android E2E session). Fix: keep the last 32 emitted DownloadProgress serializations alive in a ring slot on the sink struct (protected by the existing mutex). Every emission rotates to a fresh slot so in-flight async bindings continue to read a valid pointer until the slot recycles — which, at the 64 KiB HTTP reporting interval used by the orchestrator, gives the Dart main isolate ~2 MB of buffered payload to drain before any byte range is reused. React Native NitroModules, which also dispatches asynchronously across the JSI boundary, inherits the same benefit. The ring is freed when the callback is cleared (passed nullptr) so uninstalling the subscriber doesn't pin up to 32 buffers for the rest of the process lifetime. Documented the new contract in the public header. All 24 download-orchestrator tests still pass locally (`proto_*` suite exercises the callback path end-to-end).

…ield canonical) Complete the unification started in BUG-STREAMING-002: make `rac_llm_proto_service.cpp::dispatch_stream_event` delegate to the shared `rac::llm::serialize_llm_stream_event()` helper instead of hand-rolling its own LLMStreamEvent population. Before this change the two C++ call sites still produced the 13 proto fields through divergent code paths — the shared encoder was in place but only `dispatch_llm_stream_event` (registry path used by Swift iOS / Web) used it, while `dispatch_stream_event` (direct-callback path used by Kotlin Android JNI) still built its own `LLMStreamEvent` via `set_event_kind`/`set_request_id`/etc. A single canonical emitter now serializes every LLMStreamEvent so both paths emit byte-identical wire output for identical inputs. Secondary cleanups in `rac_llm_proto_service.cpp`: - Drop unused `using runanywhere::v1::LLMStreamEvent` and `LLMStreamEventKind` (no longer referenced after delegation). - Drop unused `now_us()` helper (timestamp now produced inside the shared serializer). - Drop `event_kind_for_token()` duplicate (replaced by the canonical `derive_event_kind()` used by both paths). In `llm_component.cpp`, replace the hand-written namespace-scoped forward declaration of `dispatch_llm_stream_event` with a `#include "features/llm/rac_llm_stream_internal.h"` so the 9-arg legacy overload and the struct-based variant stay in sync with the canonical header. Thread safety preserved: the registry path still captures (callback, user_data, seq) under the mutex and fires the callback without holding the lock (avoids deadlock on self-unsubscribe). The direct- callback path (proto_service) retains its per-invocation seq counter and uses a thread_local scratch buffer. Wire compatibility: callers that only know the 9 basic fields (all `llm_component.cpp` call sites) still emit identical bytes because unset scalars fall back to proto3 defaults inside the canonical serializer. Validation: - `ctest --test-dir build/macos-debug -R llm_stream_proto` passes (all 6 cases: seq monotonic, error termination, unregister-stop, token_id/logprob round-trip). - Pre-existing `llm_proto_service_tests` "generate reports stop finish reason" failure at line 347 is unrelated (introduced by BUG-STREAMING-003 which now emits "length" on max-token exhaust; that test assertion needs its own follow-up). - `clang-format --dry-run --Werror` clean on all touched files.

…ccess Flutter iOS Runner target was bootstrapped without a *.entitlements file, causing flutter_secure_storage to fail with OSStatus -34018 (errSecMissingEntitlement). DartBridge.Auth could not pre-load tokens and DartBridge.Device could not persist the device ID across launches, breaking SDK auth/telemetry. - Create examples/flutter/RunAnywhereAI/ios/Runner/Runner.entitlements declaring keychain-access-groups = $(AppIdentifierPrefix)com.runanywhere.runanywhereAi. - Register the file in Runner.xcodeproj (PBXFileReference + Runner group). - Set CODE_SIGN_ENTITLEMENTS = Runner/Runner.entitlements on all three Runner build configurations (Debug, Release, Profile).

… delete orphan OPFSStorage BUG-WEB-006: `tsc` does not clean declarationDir between emits, so stale `.d.ts` files for deleted V2 modules (ModelManager, ModelDownloader, ExtensionPoint, etc.) kept shipping in `@runanywhere/web` on npm (93 `.d.ts` vs 65 source files). Chain the existing `clean` script into `build` for core, llamacpp, and onnx packages: `"build": "npm run clean && tsc"`. Post-fix, the core package emits exactly 65 `.d.ts` files matching source count. BUG-WEB-008: `OPFSStorage` was 440 lines of orphan code — exported from `index.ts` but only its static `isSupported` getter was read (from `RunAnywhere.storageBackend`). No one ever instantiated it. Delete the file, drop the export, inline the 3-line OPFS capability check directly in the `storageBackend` getter, and update `StorageProvider.ts` documentation to reflect the removal. The separate architectural gap — PlatformAdapter file callbacks binding to volatile Emscripten MEMFS instead of an OPFS Sync Access Handle worker — is tracked as a follow-up row `BUG-WEB-MEMFS-VOLATILE` (non-trivial async-to-sync bridge work, out of scope for this orphan-code cleanup). Validation: `npm run build` in `packages/core` produces a clean dist with 65 `.d.ts` files and no stale `OPFSStorage.d.ts` / `ModelManager.d.ts`. All three web SDK packages typecheck cleanly.

Reduces the model-catalog parity drift between the 5 example apps. Uses the iOS re-seeded catalog (~25 models) as the canonical reference and back-fills each other example's `registerModulesAndModels` with the missing LLMs and the one-per-modality VAD baseline so every SDK surfaces a comparable core set in its model picker. - Flutter (`lib/app/runanywhere_ai_app.dart`): +Qwen2.5 1.5B Q4_K_M, +Qwen3 1.7B Q4_K_M, +Qwen3 4B Q4_K_M (thinking-mode enabled on the qwen3 family), +Qwen2-VL 2B multi-file, +LFM2-VL 450M multi-file, +Silero VAD. - React Native (`App.tsx`): +Qwen2.5 1.5B Q4_K_M, +Qwen3 1.7B Q4_K_M, +Qwen3 4B Q4_K_M (thinking-mode enabled), +Silero VAD. - Web (`src/services/model-catalog.ts`): +LFM2 350M Q4_K_M, +Qwen3 0.6B Q4_K_M (thinking-mode). Scope intentionally limited: Android's `ModelBootstrap` relies on the native catalog refresh (not local registerModel calls) and is not in scope per BUG-UX-001's lane list. MetalRT, WhisperKit, and CoreML diffusion entries remain iOS-only — their runtimes are not available on the other platforms. Backlog row removed.

Post-investigation, BUG-UX-003 is expected iOS simulator behavior, not an SDK defect. Flutter correctly uses getApplicationDocumentsDirectory() which maps to NSDocumentDirectory, matching Swift/RN/Kotlin SDK parity. Evidence: log at 2026-05-05T18:44:24 shows base dir set to .../Application/<UUID>/Documents. simctl install reuses the same container UUID on normal reinstalls, but a crash-triggered reinstall (FBSOpenApplicationServiceErrorDomain code=4 recovery) can allocate a fresh UUID with an empty Documents/. The SDK then correctly scans the NEW container and finds no downloaded models. On physical devices, Documents persists across TestFlight/App Store reinstalls. Added developer-facing caveat to DartBridgeModelPaths.setBaseDirectory so future investigators don't re-file this as a bug. No code change required. BUG-UX-003 row already removed from backlog in prior wave-F commit (a4231a2). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…file_exists on WebGPU build
The shipped `racommons-llamacpp-webgpu.{js,wasm}` artifacts (dated
2026-05-03) predated commit 9226feb (2026-05-04 23:29) which added the
15 `_rac_wasm_offsetof_platform_adapter_*` helpers + the
`_rac_wasm_offsetof_config_platform_adapter` helper to
`wasm/src/wasm_exports.cpp` and the matching entries in
`wasm/CMakeLists.txt` `RAC_EXPORTED_FUNCTIONS`. The stale WebGPU binary
was missing all 16 exports, so `PlatformAdapter.register()`
(`sdk/runanywhere-web/packages/llamacpp/src/Foundation/PlatformAdapter.ts:90-94`)
threw, and `LlamaCppBridge._doLoad` silently fell back to CPU at
`LlamaCppBridge.ts:271-277`.
Root cause: stale artifact — the source tree has been correct since
9226feb. All 15 offsetof functions carry `EMSCRIPTEN_KEEPALIVE` and
are listed unconditionally in `RAC_EXPORTED_FUNCTIONS`; there are no
WebGPU-specific exclusions in `build.sh` or the CMake flow.
Changes:
- `sdk/runanywhere-web/wasm/CMakeLists.txt` — added a BUG-WEB-003
comment above the platform_adapter export block pinning the
requirement that both CPU and WebGPU variants must export the same
symbol set and that rebuilds of `wasm_exports.cpp` require both
variants to regenerate.
- Deleted the stale local WebGPU artifacts:
`sdk/runanywhere-web/packages/llamacpp/wasm/racommons-llamacpp-webgpu.{js,wasm}`
and `examples/web/RunAnywhereAI/dist/assets/racommons-llamacpp-webgpu.wasm`
(all gitignored — local cleanup only) so the next
`./wasm/scripts/build.sh --llamacpp --webgpu` run regenerates them
from the current source.
- Removed BUG-WEB-003 from the Wave F backlog.
Requires rebuild before shipping:
./sdk/runanywhere-web/wasm/scripts/build.sh --llamacpp --webgpu
Verification (source-level, pre-rebuild):
grep -c 'rac_wasm_offsetof_platform_adapter' \
sdk/runanywhere-web/wasm/src/wasm_exports.cpp # -> 15
grep -c 'rac_wasm_offsetof_platform_adapter' \
sdk/runanywhere-web/wasm/CMakeLists.txt # -> 16
(both CPU + WebGPU use the same RAC_EXPORTED_FUNCTIONS list)

…ocs + warning cleanup BUG-RN-IOS-005: Change `console.warn` to `console.debug` for informational `isSTTModelLoaded` / `isTTSModelLoaded` breadcrumbs on RN STTScreen:176 and TTSScreen:235 so they no longer trip the "Open debugger to view warnings" LogBox banner on mount. BUG-UX-002: Add "Screenshot filename taxonomy" section to test_workflows/instructions/common/report_schema.md (gitignored test-infra doc) defining the `NNN_snake_case.png` convention and a shared keyframe table (`000_app_launch` ... `015_settings_tab`) so cross-lane diff is meaningful. Note: test_workflows/ is gitignored; doc lives on disk for lane-author reference. BUG-STREAMING-004: Replace the stale Testing section in sdk/runanywhere-kotlin/CLAUDE.md that referenced a non-existent `../../tests/streaming/` srcDir and `PerfBenchTest` / `CancelParityTest` / `ChecksumPlumbingTest` classes. Accurate section now acknowledges Flutter's `parity_test.dart` is the only extant cross-SDK streaming coverage and points at the new follow-up row `BUG-STREAMING-HARNESS-NEW` for anyone who wants to actually build the shared harness later. Backlog: delete BUG-RN-IOS-005, BUG-UX-002, BUG-STREAMING-004 rows; append new-feature row BUG-STREAMING-HARNESS-NEW with concrete scope. Validation: cd examples/react-native/RunAnywhereAI && yarn typecheck passes (exit 0). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
BUG-FLT-IOS-006: Add synchronous in-flight guard to `_downloadModel()` in both `model_selection_sheet.dart` and `model_components.dart`. Reading `_isDownloading` BEFORE `setState` debounces a rapid second tap on the Get button while the widget is still waiting for the first re-render, so the SDK receives only one `downloads.start(...)` call per user intent. BUG-FLT-IOS-007: `[LLM.LlamaCpp.GGML]` log messages were truncated to a single char "s" on Flutter iOS because `rac_logger.cpp` formatted the platform-adapter payload into a stack-local `char formatted[2048]` and then called `adapter->log()` — Flutter iOS wires that callback through `NativeCallable.listener`, which posts the raw pointer to the Dart isolate's event loop and reads it ASYNCHRONOUSLY. By the time Dart ran `.toDartString()`, the C++ stack frame had unwound and the buffer had been reused, producing the truncated "s". Marking the buffer `thread_local` gives it persistent per-thread storage so the pointer stays valid until the same thread logs its next message (after the listener has already snapshotted the text). No behavior change on synchronous adapters (Swift, JNI) — they still snapshot inline. Validation: `cd examples/flutter/RunAnywhereAI && flutter analyze` → No issues found.

…cleanup BUG-SWIFT-IOS-005 (MetalRT product declaration): The example app called `MetalRT.register(priority:100)` guarded by `#if canImport(MetalRTRuntime)` but `Package.swift` never declared `RunAnywhereMetalRT` as a target dependency, making the guard silently false on external SPM consumers. Per Wave F rule #6 (MetalRT is deferred scope — alongside Genie, WhisperCPP, Diffusion, whisperkit_coreml, CoreML runtime, Metal runtime), this dead code is removed rather than fixed by adding the product declaration. Re-add the import, registration call, and the two MetalRT model-seed entries when the backend is promoted out of deferred scope and `RunAnywhereMetalRT` is declared as a product+target dependency. BUG-SWIFT-IOS-006 (Swift 6 warnings): Migrated two iOS-17-deprecated `onChange(of:) { _ in }` call sites in `VoiceAssistantView.swift` (lines 155 + 300) to the two-parameter `onChange(of:) { _, _ in }` closure variant. The remaining `nonisolated(unsafe)` use at `VLMViewModel.swift:39` is the correct Swift 6 pattern for cancelling a `Task` from `deinit` (which is nonisolated in Swift 6) and is retained intentionally — the adjacent comment documents the rationale. Validation: `xcodebuild build -scheme RunAnywhere -destination 'platform=iOS Simulator,name=iPhone 17'` succeeds with zero warnings from the example app. The only warning in the full build log is the pre-existing `CRACommons.h` umbrella-header notice inside the SDK, unrelated to this scope.

BUG-WEB-004: Misclassification — superseded by BUG-WEB-010 (both backend
packages have real implementations, not empty stubs). No code change.
BUG-WEB-010: Rewrite the `feature-unavailable` placeholder text in
`examples/web/RunAnywhereAI/src/components/feature-unavailable.ts` to
describe current state (LlamaCPP wired via `LlamaCPP.register()`;
SherpaONNXBridge wired but gated on `RAC_WASM_ONNX` per CPP-13) instead
of claiming the backend packages are "empty stubs".
BUG-WEB-007: Replace the hardcoded `<span>0.1.0</span>` in the Settings
tab (`examples/web/RunAnywhereAI/src/views/settings.ts:73`) with
`${RunAnywhere.version}` by importing `RunAnywhere` from
`@runanywhere/web`.
BUG-WEB-009: Remove the `sherpa-onnx.wasm` entry from
`examples/web/RunAnywhereAI/vite.config.ts` `copyWasmPlugin`.
`SherpaONNXBridge` never loads that file (all STT/TTS/VAD routes through
`racommons-llamacpp.wasm` proto-byte adapters), so copying 12 MB into
`dist/assets/` was pure deploy-size bloat.
BUG-WEB-005: Drop the `FORCE` on the Emscripten `RAC_BACKEND_RAG=OFF`
cache entry in `sdk/runanywhere-commons/CMakeLists.txt` and add an
explicit `-DRAC_BACKEND_RAG=${RAG}` pass-through in
`sdk/runanywhere-web/wasm/scripts/build.sh` so callers can opt in once
the onnxruntime-wasm third_party package lands (TODO(v0.21)).
Deleted BUG-WEB-{007,009,010} rows from
`gaps/gaps/inconsistencies/IMPLEMENTATION_BACKLOG.md` and added a
`RESOLVED (Wave F-4 web)` summary covering all five IDs.

…G-STREAMING-003 fix BUG-STREAMING-003 (commit 3d2ed00) correctly emits finish_reason="length" when completion_tokens equals max_tokens. The mocked generation at test_llm_proto_service.cpp:97 returns completion_tokens=12 when options->max_tokens=12 (set at line 272), so this mocked run now legitimately ends with "length", not "stop". Update the assertion at line 347 to match the corrected production behavior. Test count: 67/67 now passes (was 66/67). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Medium Risk
Moderate risk because it replaces the PR CI build workflow and introduces a new root CMake/preset-based build entrypoint that could break cross-platform builds if presets or helper macros diverge from existing scripts.
Overview
Build/CI overhaul for the v2 migration. Adds a root
CMakeLists.txt+CMakePresets.jsonas the single native build entrypoint, plus new shared CMake helpers (cmake/platform.cmake,cmake/plugins.cmake,cmake/protobuf.cmake,cmake/sanitizers.cmake) to standardize platform detection, plugin target creation/force-load, protobuf detection/codegen, and sanitizer flags.GitHub Actions changes. Replaces the previous path-filtered, script-driven
pr-build.ymlwith a smaller preset-based matrix (macOS/Linux/iOS/Android + per-SDK wrapper checks), addsidl-drift-check.ymlto regenerate bindings and fail on drift, and addsstreaming-perf.ymlto build/run streaming parity/perf fixtures and upload artifacts.SDK/tooling + docs updates. Marks generated binding trees as
linguist-generatedin.gitattributes, updates Swift SPM to depend onswift-protobufand exclude unused generated*.grpc.swiftstubs (plus flipsuseLocalNativestotrue), makes Android NDK path configurable viaracNdkVersion, and adds/updates several architecture/migration/release documents and SDK docs to reflect proto-stream voice agent usage and current package versions.Reviewed by Cursor Bugbot for commit 801cac4.
