fix(swift,rn): honor LoadOptions contextLength and ordered backendPreferences - #950
Merged

Four lessons from cutting v0.20.33, which took four candidates. Two were real
defects that would have shipped an SDK where TTS does not link.
The expensive one: a new NeuRT archive must be added in FOUR places, and three
only fail in a build configuration a dev Mac never produces. Miss the force-load
lists and every native job is green while validate_consumer_flutter dies an hour
later on `Undefined symbol: _g_neurt_tts_ops` -- the engine registers, all CMake
targets compile, only a CONSUMER's link fails. Miss the `#if RAC_NEURT_ROUTABLE`
guard on the vtable entry and the opposite happens: routable builds are fine and
every PR job without NEURUN_TOKEN fails, because the non-routable shell still
references a symbol nothing defines. A machine with the payload staged is
routable and reproduces neither.
This file already notes that prose alone did not stop the checksum-staleness bug
recurring twice, so the archive-list half now has a mechanism:
`neurt_assert_no_unlisted_archives` fails packaging by name. The vtable guard has
none -- hence the instruction to audit all ten slots, and the note that moving
core/third_party/neurt aside reproduces a non-routable build in one step.
Also recorded: reuse_native_web_run_id is same-version-only (the wasm embeds
RAC_VERSION_STRING, and a skipped native_web leaves the candidate unusable for
publish_from_run_id); checksum verification must match by NAME as well as URL,
because a URL-only cross-check validates 9 of 15 sites and reports success; and
`rcli backends --json` against the OSS kit lists no neurt at all, so a
routability check there passes cleanly and proves nothing.

…ired on load ModelLoadRequest already carries context_length (tag 6) and the ordered backend_preferences list (tag 9), so requireCarriableByLoadABI() was a false preflight: it rejected both knobs and silently dropped BackendPreference.required while claiming the native load ABI could not carry them. Forward both knobs on the load request (contextLength clamped into the wire int32) and fail preflight on a `required` preference, because backend_preferences carries framework enums only. `threads` (retired, reserved tag 7) and `accelerator` stay rejected, and the now-stale loadOptions entries leave RunAnywhere.capabilities().unavailable. Aligns the Swift load path with Web (RunanywhereAI#785), Flutter (RunanywhereAI#786) and Kotlin. Fixes RunanywhereAI#882

loadResolved() skipped options.backendPreferences.first whenever it was
.unspecified and fell through to the catalog's model.framework, pinning the
legacy RAModelLoadRequest.framework field to the catalog backend. That pin
outranks the later entries in the ordered backend_preferences list, so a
caller's declared backend order was silently broken.
Keep the first preference regardless of its value and only fall back to
model.framework when no preference was supplied, matching React Native
(framework: requestedBackend.backend) and Kotlin
(requestedBackend?.backend ?: registered.framework.takeIf { it.value != 0 }).

The model_types.proto contract changed, so advance the patch schema version and keep SCHEMA_LOCK metadata synchronized.
RunanywhereAI/RCLI was renamed to RunanywhereAI/wally, and both install scripts now install a binary called wally (install.sh:147,154 and install.ps1:144 on wally main 02d8d06). So every `rcli ...` example in the README failed for anyone who followed it end to end. This renames the binary, the repo links and the install URLs in the quick start, the terminal details section, the SDK and feature table rows, the OpenAI-compatible server section and the platform table. The commands and flags themselves are unchanged. wally main still registers pull (an alias of models download), run with --no-think and --image, tts, stt, voice, vad, embed, image, lora, serve on port 8080, and a global --json. The Homebrew lines are removed. runanywhereai/tap still has only Formula/rcli.rb (0.20.24, last commit e9c777b on Aug 18), which installs rcli, not wally, and wally's own README documents only the two install scripts. The brew line can come back once the tap ships a wally formula. Left as is on purpose: - The "RCLI WORKS" string in the transcript is the recorded model output for that prompt, and it hasn't been re-captured under wally. - The MetalRT paragraph and the "Real projects" entry describe RCLI as a MetalRT-powered voice assistant with 40+ system actions. wally's own AGENTS.md calls MetalRT retired, so a straight rename would make a claim about wally that I can't back. Refs RunanywhereAI#886 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
- `wally serve` is LLM-only and registers /v1/chat/completions and /v1/models (plus /health), not the Python server's full endpoint set. - install.sh only ships linux-x86_64; any other Linux arch fails with "x86_64 only", so drop aarch64 from the requirements table. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
wally 0.6.0 has no top-level `pull`: register_models_aliases() is defined in cmd_models.cpp but never called from app.cpp, so only the `models pull` subcommand is reachable. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Do not set framework for one .unspecified preference.
With exactly one .unspecified preference, the current condition falls through to model.framework. The shared resolver treats that field as authoritative and does not consult model.preferred_framework. If those catalog values differ, the loader can select model.framework instead of the catalog-preferred backend.
Keep the existing multi-entry behavior, but only use model.framework when no backend preference was supplied.

Merge the current main branch while preserving the load-options fixes and accepted upstream changes. Retain the updated streaming documentation. Advance the comments-only schema revision to 1.5.1 and regenerate the schema lock from the final 41-proto set.

Thanks a lot for this, @shubhamsinnh! Carrying contextLength and the ordered backendPreferences list across the wire closes a gap the previous comment had documented as "throws rather than being silently dropped" — and doing it by extracting a shared modelLoadRequest(...) builder (ModelsNamespace.swift:531) so explicit and automatic loading build the same request is the right shape: one place constructs it, both paths get the fix, and the SDK can no longer drift from what the native ABI actually accepts.
Checked: CodeRabbit reviewed the latest commit · CI green, no failures · merged into main and compiled the changed core translation unit locally · two independent code reviews. A few specifics worth recording:
contextLengthreaches the core. Swift assigns it atModelsNamespace.swift:531, React Native atModels.ts:376; both serialize the whole request and forward the bytes torac_model_lifecycle_load_proto. Nothing drops it on the way down.- Order is preserved.
resolvedBackendPreferencesreturns the caller's list verbatim, and the core consumes it in the listed order atmodel_lifecycle.cpp:878(pin_candidates), selecting the first registered engine for the primitive. An empty or unspecified preference behaves as before — no silent reordering of existing behaviour. - The IDL change is comment-only and the lock is honest. No field added, removed or renumbered, so wire compatibility is unchanged;
schema_lock.sh --checkreports✓ 1.5.1 / 54812f1f… (41 protos)against the protos it ships with, including the deliberate1.5.0 → 1.5.1bump. - The core addition is a negative-
context_lengthguard (+10 lines), paired withrequireValidContextLengthon the RN side rejecting non-integers, negatives and values above2^31-1before the wire. It does not touch the reload decision that#949/#980own in the same file, so the two compose rather than collide.
One thing from the review worth knowing, not blocking: the ordered list selects among available engines — it does not retry if a chosen backend fails to initialize. That matches the current ABI and is the sensible reading of "preferences"; if you ever want true fallback-after-failure, that is a core change rather than a binding one.
Follow-ups, not blocking: the threads/accelerator knobs still fail preflight here, and the docstring now says why, which is the honest state.

…ferences (RunanywhereAI#950) * docs: record the v0.20.33 release traps Four lessons from cutting v0.20.33, which took four candidates. Two were real defects that would have shipped an SDK where TTS does not link. The expensive one: a new NeuRT archive must be added in FOUR places, and three only fail in a build configuration a dev Mac never produces. Miss the force-load lists and every native job is green while validate_consumer_flutter dies an hour later on `Undefined symbol: _g_neurt_tts_ops` -- the engine registers, all CMake targets compile, only a CONSUMER's link fails. Miss the `#if RAC_NEURT_ROUTABLE` guard on the vtable entry and the opposite happens: routable builds are fine and every PR job without NEURUN_TOKEN fails, because the non-routable shell still references a symbol nothing defines. A machine with the payload staged is routable and reproduces neither. This file already notes that prose alone did not stop the checksum-staleness bug recurring twice, so the archive-list half now has a mechanism: `neurt_assert_no_unlisted_archives` fails packaging by name. The vtable guard has none -- hence the instruction to audit all ten slots, and the note that moving core/third_party/neurt aside reproduces a non-routable build in one step. Also recorded: reuse_native_web_run_id is same-version-only (the wasm embeds RAC_VERSION_STRING, and a skipped native_web leaves the candidate unusable for publish_from_run_id); checksum verification must match by NAME as well as URL, because a URL-only cross-check validates 9 of 15 sites and reports success; and `rcli backends --json` against the OSS kit lists no neurt at all, so a routability check there passes cleanly and proves nothing. check_agents_claude_sync.sh All 19 CLAUDE.md -> AGENTS.md symlinks present Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01R6p1R4pwTg5pvVjiEjq9ZA * fix(swift): forward contextLength and backendPreferences, reject required on load ModelLoadRequest already carries context_length (tag 6) and the ordered backend_preferences list (tag 9), so requireCarriableByLoadABI() was a false preflight: it rejected both knobs and silently dropped BackendPreference.required while claiming the native load ABI could not carry them. Forward both knobs on the load request (contextLength clamped into the wire int32) and fail preflight on a `required` preference, because backend_preferences carries framework enums only. `threads` (retired, reserved tag 7) and `accelerator` stay rejected, and the now-stale loadOptions entries leave RunAnywhere.capabilities().unavailable.

Fixes RunanywhereAI#882 * docs(swift): correct models.load doc for forwarded load options * fix(swift): preserve first backend preference even when unspecified loadResolved() skipped options.backendPreferences.first whenever it was .unspecified and fell through to the catalog's model.framework, pinning the legacy RAModelLoadRequest.framework field to the catalog backend. That pin outranks the later entries in the ordered backend_preferences list, so a caller's declared backend order was silently broken. Keep the first preference regardless of its value and only fall back to model.framework when no preference was supplied, matching React Native (framework: requestedBackend.backend) and Kotlin (requestedBackend?.backend ?: registered.framework.takeIf { it.value != 0 }). * fix(swift): reject unrepresentable model context lengths LoadOptions.contextLength uses Swift Int while ModelLoadRequest.context_length uses int32. Int32(clamping:) silently changed values outside the wire range. Use an exact conversion and reject unrepresentable values with invalidConfiguration instead. * docs(core,swift): propagate UTF-8 text-run streaming docstrings across LLM and VLM headers (RunanywhereAI#929, RunanywhereAI#923) Update stale "Called for each generated token" docstrings to describe delivery as UTF-8-safe text runs generated by the model.

So every `rcli ...` example in the README failed for anyone who followed it end to end. This renames the binary, the repo links and the install URLs in the quick start, the terminal details section, the SDK and feature table rows, the OpenAI-compatible server section and the platform table. The commands and flags themselves are unchanged. wally main still registers pull (an alias of models download), run with --no-think and --image, tts, stt, voice, vad, embed, image, lora, serve on port 8080, and a global --json. The Homebrew lines are removed. runanywhereai/tap still has only Formula/rcli.rb (0.20.24, last commit e9c777b on Aug 18), which installs rcli, not wally, and wally's own README documents only the two install scripts. The brew line can come back once the tap ships a wally formula. Left as is on purpose: - The "RCLI WORKS" string in the transcript is the recorded model output for that prompt, and it hasn't been re-captured under wally. - The MetalRT paragraph and the "Real projects" entry describe RCLI as a MetalRT-powered voice assistant with 40+ system actions. wally's own AGENTS.md calls MetalRT retired, so a straight rename would make a claim about wally that I can't back.

Description
Fixes #882.
Swift and React Native rejected
contextLengthand ordered backend preferences even thoughModelLoadRequestcan carry both fields. They also accepted a required backend preference without representing that constraint on the wire.Both bindings now forward the context length and complete preference list, reject required preferences, and retain the existing rejection of threads and accelerator options. Context values must be non-negative and fit int32; React Native also rejects fractions and non-finite numbers before encoding. Shared core validation rejects negative values from direct native callers too.
React Native reports the backend returned by native loading rather than the first requested backend. A lone unspecified preference leaves the optional framework field absent so Commons can honor the catalog's preferred framework, even when it differs from the model framework. An unspecified entry before later preferences preserves the caller's ordering. Swift capability reporting exposes the remaining required-preference limitation.
The branch incorporates
mainatf8aabbbf5, retaining the accepted upstream streaming documentation and newer native/schema features. Its documentation-only schema change uses IDL version1.5.1, withSCHEMA_LOCKregenerated from the complete final set of 41 schemas.Context configuration remains advisory at the engine boundary, as required by the existing engine contract. MLX and QHexRT do not currently configure session creation from this request field. Native warnings are surfaced through
fallbackReason; adding adjustable context support to those runtimes is outside this binding fix. No public runtime callback ABI or SDK release version is changed.Reviewer guidance: inspect the encoded request, the lone/mixed unspecified preference cases, React Native's actual-backend mapping, and the schema lock relative to
main.Type of Change
The small Swift request-builder extraction makes the production mapping directly testable; it adds no public API.

Consistency and version-bump validation passed against the exact capturedmainlock:bash idl/codegen/schema_lock.sh --check --require-bump build/pr950-review/SCHEMA_LOCK.main.core/src/core/model_lifecycle.cpppassed a C++20 syntax-only compilation using the configured MinGW compiler and regenerated headers. This was not a linked native build or native test run.git diff --checkandgit diff --cached origin/main --checkpassed. The contribution-scope audit compares the final result with the capturedmain, rather than treating accepted upstream changes as part of this fix.The commit-time hook reported that Lefthook was unavailable on PATH; the checks listed above were run directly rather than through that hook.
Exact package/test entry points used:
The full Jest suite passed on the merged tree without new test changes. The source-text assertions use canonical checkout bytes; their files have no contribution diff.
Seven Swift tests cover encoded request mapping, context bounds/default presence, required-preference rejection, capability reporting, and backend ordering. The single-unspecified case uses differing model and preferred frameworks and checks that framework absence survives protobuf encoding. They cannot be executed on this Windows host. Full
generate_all.shwas attempted on the merged 41-proto set and stopped at missingprotoc-gen-swift; the separate TypeScript/C++ generation above passed. Full all-language generation and its drift gate still require CI validation, and lock consistency alone is not claimed as proof that every language was regenerated locally. Swift builds/tests and strict SwiftLint also remain unverified locally. The existingswift-spmjob performs them, andpr-build.ymlis eligible to run on a new update now that this PR targetsmain; check that the jobs actually run and pass before treating Apple validation as complete. The overall lint checkbox remains unchecked because SwiftLint has not run locally. No linked native build, native test execution, device inference, or MLX/QHexRT execution is claimed for this integration.Platform-Specific Testing (check all that apply)
Swift SDK / iOS Sample:
Apple execution is pending macOS CI; no simulator or device session was run locally.
Kotlin SDK / Android Sample:
No Kotlin binding change or Android device execution in this contribution.
Flutter SDK / Flutter Sample:
No Flutter binding change or Flutter device execution in this contribution.
React Native SDK / React Native Sample:
Node-hosted core tests and typechecking passed; native device execution has not been performed.
Web SDK / Web Sample:
No Web binding or browser-storage change; browser execution was outside this validation.

Checklist
No public API migration is required. Previously unsupported required/threads/accelerator options still fail preflight, invalid context values are rejected, and valid requests retain their complete preference order. The runtime context limitation and unperformed platform checks are described above; no changelog or release bump is needed for this existing bug-fix contribution.
Screenshots
No UI layout or rendering changes. Mobile, tablet, and desktop screenshots do not demonstrate the request-encoding and routing behavior; validation evidence is provided under Testing.
