Fixes #917

Summary of Changes

  • Protobuf Mapping: Mapped \StructuredOutputMode\ (\CONSTRAINED, \VALIDATION_ONLY, \REPAIR) into proto \StructuredOutputOptions.mode\ across Swift, Kotlin, Flutter, React Native, and Web bindings.
  • Enabled Constrained Decoding by Default: Updated SDK \generateStructured\ APIs to default to \constrained\ mode (which uses GBNF grammar sampling in commons) instead of throwing preflight unsupported exceptions or defaulting to \�alidationOnly.
  • Docs and Comments: Updated stale docstrings, comments, and references across Core C++ and SDK bindings to accurately reflect that constrained decoding is supported via llama.cpp sampler grammar on the LLM generate path.

Summary by cubic

Fixes #917 by mapping StructuredOutputMode (constrained, validationOnly, repair) into the proto StructuredOutputOptions.mode across the Swift, Kotlin, Flutter, React Native, Python, and Web bindings and making constrained the default for generateStructured. This replaces the previous preflight failure and validationOnly default. Constrained decoding now uses schema-derived GBNF grammar sampling via the llama.cpp sampler on the LLM generate path. SDK-side repair retry loops were dropped: repair is passed through as a proto mode, and generateStructured now forces tool choice to none. Comments and docstrings that called constrained decoding unsupported or not yet wired in were updated.

  • Kotlin LlmOptions gains a structuredOutput field whose mode overrides the generateStructured mode argument; strict is not forwarded to the proto.
  • The Python bridge exposes only constrained; other modes raise not_implemented.
  • The branch also picks up merged docs updates, including the rcli to wally CLI rename and corrected streaming-callback docstrings.

Written for commit 95e39db. Summary will update on new commits.

Summary by CodeRabbit

  • New Features
    • Structured output now defaults to constrained generation, using the supplied schema to guide output where supported.
    • Structured output settings let you choose an enforcement mode; settings provided in LLM options take precedence over the method’s mode argument.
    • Structured output options now include a mode across supported SDKs.
  • Behavior Changes
    • Structured generation no longer retries invalid results with a repair prompt. Results are extracted and validated after generation.

Walkthrough

Structured-output options now carry mode values into proto options across SDK bindings. Generation APIs in Flutter, Kotlin, React Native, Swift, and web default to constrained mode. Several bindings remove method-level repair retries. Python defaults its mode to constrained and rejects unsupported modes.

Merge Risk: High · previous review 95e39

The Flutter binding currently fails to compile because of a missing import, and Web structured generation fails for worker-owned models. Fix both before merging. The Swift mode-precedence difference and the stale README sample output are smaller follow-ups.

Security architecture risk: Low · up to d653a

Structured generation will use constrained decoding by default in several SDKs. The reviewed paths still validate generated output against the requested schema, and invalid grammar compilation fails rather than silently switching to unconstrained generation. No security finding was established, but cross-platform behavior and downstream usage remain incompletely covered.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The independently reachable surface is each SDK caller’s structured-generation request and any application behavior that consumes its result. The reviewed change does not establish expanded service, tenant, credential, or data-store authority.

Trust Boundaries and Controls

  • observed — Caller-supplied prompt, schema, and mode cross the SDK-to-core request boundary. In the inspected React Native path, schema compilation fails closed for constrained generation and generated text is separately submitted for schema validation.

Resilience and Maintainability Implications

  • observed — Kotlin marks a result valid only when parsing reports valid; its repair path reuses the selected schema and mode and validates the second generation before returning.

Explanation

The description explains the implementation and linked issue, but it omits most required template sections, including Type of Change, Testing, platform-specific testing, Labels, Checklist, and Screenshots.

Resolution

Add the required template sections and complete the applicable checkboxes. Include test results for each affected SDK and confirm the relevant labels, checklist items, and screenshots or state that screenshots are not applicable.

Full details: Linked Issues check

Explanation

Issue #917 requires agreement between structured-output defaults and documentation, plus working mode mapping or corrected mode documentation. The PR adds mode mappings and changes defaults to constrained across SDKs. The Flutter implementation still uses RunAnywhereLLM.shared in llm.dart without importing the file that defines RunAnywhereLLM. Dart imports are not transitive, so this changed implementation does not compile.

Resolution

Add the direct Flutter import for RunAnywhereLLM, or use the correct imported API. Run the Flutter analyzer or compile check.

Full details: Out of Scope Changes check

Explanation

The PR also changes documentation for the rcli to wally CLI rename and streaming-callback behavior in VLM-related files. These changes do not implement issue #917 mode mapping, structured-output defaults, or structured-output documentation.

Resolution

Remove the unrelated CLI and VLM streaming-callback documentation changes, or link them to a coding objective that requires them.

🟡 Minor · Let core own the REPAIR retry. · LlmNamespace.kt:136-150

bindings/kotlin/src/main/kotlin/com/runanywhere/sdk/public/api/LlmNamespace.kt:136-150
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Let core own the REPAIR retry.

When REPAIR is selected, Kotlin maps it into the core request. Core already performs one repair generation. If that result remains invalid, Kotlin enters lines 147–150 and starts another generation. That request also carries REPAIR, so core may retry again.

Remove the local retry block. The existing return path preserves valid initial and core-repaired results.

Suggested fix
-        if (mode == StructuredOutputMode.REPAIR && parsed.validation?.is_valid != true) {
-            val repairPrompt = structuredRepairPrompt(prompt, generation.text, schema)
-            generation = generateStructuredUnary(repairPrompt, opts, structuredOutput)
-            parsed = parseStructuredOutput(generation, structuredOutput)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Remove the Swift-side repair generation.

When mode is .repair, core already performs its repair generation. If that repaired output remains invalid, generate returns it with invalid validation state. This method then builds another repair prompt and calls generate again, causing a second repair generation outside the core-owned repair contract.

Suggested fix
             var parsed = try RunAnywhere.parseStructuredOutput(text: generation.text, schema: schema)

             let isValid = parsed.hasValidation ? parsed.validation.isValid : false

Preserve structured-output semantics when tools are active.

With registered or explicit tools and a non-.none tool choice, generate enters the tool loop. That request is built from RAToolCallingOptions, so structuredOutput is lost. The default .constrained call can then return unconstrained output. Before calling generate, set effective.toolChoice = .none, or reject this combination.

98-102: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Keep existing positional strict calls source-compatible.

The initializer now takes mode: before strict:. Swift requires labeled arguments in declaration order. A call that passes both arguments still compiles. However, any reordering or a future positional overload is risky. More important, this matches the Kotlin ordering change. Put mode after strict in both SDKs for consistency.

         schema: JsonSchema,

Thanks for this, @Adityakk9031! Mapping StructuredOutputMode consistently across the SDKs and updating the docs is worth doing, and the mapping itself is right.

One thing is a hard build break, though:

  1. bindings/kotlin/src/main/kotlin/com/runanywhere/sdk/public/api/MappingOptions.kt:121 — the diff removes the closing */ of the KDoc block that opens at line 115, without removing the opener. The comment therefore runs on and swallows the internal fun StructuredOutput.toProto() declaration below it, so the file no longer parses. A quick check on this head: the file has five /* and only four */. ./gradlew compileDebugKotlin will fail on it.

    The Kotlin job never ran for this PR (it targets temp/development, and the build matrix only triggers for main/dev/feat/v2-architecture), which is why CI did not already tell you — but the file as committed cannot compile.

One non-blocking note from review: .repair is now forwarded to commons while the SDK retry at LLMNamespace.swift:99-106 is retained, and commons already retries once internally (llm_module.cpp:2467). If both native attempts fail validation, the SDK calls commons again, which can mean four generation passes rather than the documented two. Worth a look once the build is fixed.

Once the terminator is back we'll take another look. Thanks!

Thanks — I checked it, and the build break is fixed: the file now parses (/* and */ both at five), the docstring closes properly and StructuredOutput.toProto() is no longer swallowed by the comment. That was the important part, and it's resolved.

Running the Kotlin SDK's own lint on the new head, the failure mode changed from "KtLint failed to parse file" to ordinary style violations — so what's left is formatting, not a syntax error:

MappingOptions.kt:12:1  Imports must be ordered in lexicographic order without any empty lines in-between (standard:import-ordering)
MappingOptions.kt:122:16  A multiline expression should start on a new line (standard:multiline-expression-wrapping)
Options.kt:59:35  Expected newline before annotation (standard:annotation)
Options.kt:59:49  Expected newline after last annotation (standard:annotation)

./gradlew ktlintFormat from bindings/kotlin should clear all four automatically. Worth knowing these were not visible before because the parse error masked them — the linter stops at the first file it cannot read.

Thanks — checked again and you're nearly there: down from four violations to one.

Still failing on the new head (a5b81945):

MappingOptions.kt:12:1  Imports must be ordered in lexicographic order without any empty lines
                        in-between with "java", "javax", "kotlin" and aliases in the end
                        (standard:import-ordering)

It's the aliased imports: ktlint wants plain imports first in lexicographic order, then every ... as Alias import at the end (also lexicographic). Right now the aliases (ChatMessage as, DiarizationOptions as, …) are interleaved with the plain ones. I applied exactly that reordering locally and ./gradlew ktlintCheck came back BUILD SUCCESSFUL, so this is the last thing standing between the PR and a green lint:

import ai.runanywhere.proto.v1.DiffusionGenerationOptions
import ai.runanywhere.proto.v1.EmbeddingsOptions
... (all plain imports, lexicographic) ...
import com.runanywhere.sdk.generated.convenience.defaults
import ai.runanywhere.proto.v1.ChatMessage as ProtoChatMessage
import ai.runanywhere.proto.v1.DiarizationOptions as ProtoDiarizationOptions
... (all aliased imports, lexicographic) ...

./gradlew ktlintFormat from bindings/kotlin should do it for you automatically — that's less error-prone than hand-ordering.

Thanks — down to one, and I've worked out exactly what ktlint wants.

The remaining rule is that aliased imports sort after every non-aliased one, regardless of alphabetical position. Right now the aliases are interleaved with the plain imports (ChatMessage as ProtoChatMessage sits first, ReasoningMode as ProtoReasoningMode sits in the middle), so MappingOptions.kt:12 trips standard:import-ordering.

The fix is to keep the plain imports alphabetical, then move all six aliases to the end:

import ai.runanywhere.proto.v1.DiffusionGenerationOptions
import ai.runanywhere.proto.v1.EmbeddingsOptions
// … the rest of the plain imports, unchanged …
import ai.runanywhere.proto.v1.VLMImage
import com.runanywhere.sdk.generated.convenience.defaults
import ai.runanywhere.proto.v1.ChatMessage as ProtoChatMessage
import ai.runanywhere.proto.v1.DiarizationOptions as ProtoDiarizationOptions
import ai.runanywhere.proto.v1.ReasoningMode as ProtoReasoningMode
import ai.runanywhere.proto.v1.ReasoningOptions as ProtoReasoningOptions
import ai.runanywhere.proto.v1.SegmentationOptions as ProtoSegmentationOptions
import ai.runanywhere.proto.v1.StructuredOutputMode as ProtoStructuredOutputMode

I verified this on your current head: after that reordering, ./gradlew ktlintCheck from bindings/kotlin goes from failing to BUILD SUCCESSFUL. ./gradlew ktlintFormat will do it for you — that is the safest route since it also catches anything else in the file.

One thing worth flagging about your IDE: if Android Studio is set to not reorder imports on save, it will keep putting this back — the "Optimize imports on the fly" setting uses its own ordering, which does not know ktlint's alias rule. Running ktlintFormat before you push avoids the round trip.

Nothing else on this one — the docstring/parse fix you did earlier was the important part, and this is the last formatting step.

Thanks for sticking with this one, @Adityakk9031 — mapping StructuredOutputMode end to end and replacing the stale "not wired in yet" comments is exactly the right fix for #917, and dropping the per-SDK repair loop in favour of commons' single retry is a real simplification.

The head still can't build, in two places, and both are small fixes:

  1. bindings/kotlin/src/main/kotlin/com/runanywhere/sdk/public/api/LlmNamespace.kt:143 — opts.structuredOutput does not exist. LlmOptions (Options.kt:83) declares no such property and nothing else in bindings/kotlin/src supplies one as an extension, so compileDebugKotlin fails here and at :144. Swift (Options.swift:143), Flutter (options.dart:214) and RN (Types.ts:164) all carry the field — adding it to LlmOptions is the parity-correct fix, and it also retires the now-false "No structured-output schema field" comment at Options.kt:98-99 and MappingOptions.kt:45-47; dropping the two reads is the alternative. While you're there, :153 reports mode = mode (the parameter) instead of effectiveMode, so a caller who sets options.structuredOutput.mode gets a StructuredResult claiming the argument's mode — one-word fix.

  2. bindings/flutter/packages/runanywhere/lib/public/api/namespaces/llm.dart:141 — toolChoice: const ToolChoice.none() calls none as a function, but it is a plain static const field (options.dart:125) and the class has no call() operator and no extension adds one. flutter analyze fails with "isn't a function". Drop the parens: toolChoice: ToolChoice.none.

Neither CI job has run for this PR — pr-build.yml only triggers on main, dev and feat/v2-architecture, and this targets temp/development — which is how both reached review unnoticed. While you are in these files: structuredRepairPrompt (LlmNamespace.kt:255) lost its only caller when the retry loop came out (base called it at old line 155), so it and its Swift twin (LLMNamespace.swift:435) are now dead code — deleting both is free and keeps the two trees honest.

One more, away from the build: Web is half-ported. The new mode branch in Mapping.ts:315-334 is unreachable because its only caller still preflight-rejects constrained (Namespaces/llm.ts:301-305) and still defaults to validationOnly (:298), so Web is the one SDK that can't opt into constrained decoding — the opposite of the PR's stated goal. It is also a behaviour change from base: there the mapper ignored the mode argument entirely, so an unset mode meant the schema was compiled to GBNF; at head Web sends VALIDATION_ONLY explicitly and commons skips the grammar. Either wire it up like the other SDKs (default constrained, drop the throw) or say in the PR why Web must stay validation-only.

Optional, not blocking: Swift overwrites options.structuredOutput.mode with the method argument (LLMNamespace.swift:93) while Flutter, RN and Kotlin let the options win — if you touch that line, making the four agree on one precedence (and saying which in the doc comment) would be a nice tidy-up.

CodeRabbit's two remaining test-coverage notes still apply (r4262310059, r4262310068) — we're not asking for them here, since the repo convention is no new tests unless the change calls for them.

Not blocking this PR: I opened #{issue} for the Python side of the same story — StructuredOutput.mode exists but generate_structured has no way to select a mode, so Python users can't get validationOnly or repair. You're welcome to pick it up if you're interested.

Once the two builds are green we'll take another look — this should be one more push.

Thanks for sticking with this one, @Adityakk9031 — both build breaks from the last round are genuinely fixed: LlmOptions.structuredOutput now exists (Options.kt:116) so Kotlin compiles, and toolChoice: ToolChoice.none is a field reference again (llm.dart:141). The mode mapping, the constrained-by-default switch and the single commons-owned repair retry all read right.

One thing still stops the Flutter SDK from compiling:

  1. bindings/flutter/packages/runanywhere/lib/public/api/namespaces/llm.dart:150 — RunAnywhereLLM.shared.extractStructuredOutput(...) names a class this file never imports. RunAnywhereLLM is declared only in lib/public/capabilities/runanywhere_llm.dart:34, none of llm.dart's imports re-exports it (types/options.dart exports three pbenums and nothing else), and Dart imports are not transitive — so dart run melos run analyze in the flutter-pubget job fails on an undefined identifier. Add import 'package:runanywhere/public/capabilities/runanywhere_llm.dart'; to the import block (that file does not import namespaces/llm.dart, so there is no cycle), or reach the same extraction through the extension already imported at line 27. flutter analyze in bindings/flutter/packages/runanywhere confirms it.

Two notes on the branch itself, not on your change. The required PR build matrix still cannot run here — it triggers on main/dev/feat/v2-architecture and this targets temp/development. And the tree does not currently merge into main, but that conflict is in core/include/rac/features/llm/rac_llm_component.h, a docstring none of your commits touch, inherited from temp/development itself (git merge-tree origin/main origin/temp/development conflicts in the same file with no PR involved). Nothing for you to do there.

Optional, not blocking, in files you already touched:

  • bindings/swift/Sources/RunAnywhere/Public/RunAnywhere.swift:633 still lists generateStructured.constrained under unavailable with "not wired in yet; use .validationOnly or .repair" — stale now that .constrained is the default.
  • bindings/kotlin/src/main/kotlin/com/runanywhere/sdk/public/api/LlmNamespace.kt:84 passes no structuredOutput, so the new LlmOptions.structuredOutput is inert on plain llm.generate; Swift (Options.swift:210), Flutter (options.dart:310-312) and RN (Options.ts:202-203) forward it there, and Web's LlmOptions (bindings/web/packages/core/src/Public/API/Options.ts:90-118) has no such field at all.

One thing worth knowing about validationOnly: the mode now reaches commons correctly, but on the ordinary generate path commons still does not render includeSchemaInPrompt into the system prompt (llm_module.cpp:1502 reads only options.system_prompt; that gap is open as #916 from PR #840), so free generation with no schema in the prompt will usually come back invalid. Your mapping is right — that is the tracking issue for the rest.

Not blocking this PR: I opened #{issue:1} for the Python surface (StructuredOutput.mode exists but generate_structured cannot select one) and #{issue:2} for the docstrings claiming grammar-constrained decoding on backends that never consume the grammar arm (MLX is the preferred Apple backend at priority 110 and has no grammar handling; QHexRT rejects an unprefixed GBNF payload). You're welcome to pick either up if you're interested.

Once the Flutter lane compiles we'll take another look — this should be the last round. Thanks for pushing it this far.

Correction to the review above: two issue references came through as raw placeholders. The two follow-ups I mentioned are:

Nothing else in that comment changes, and the one blocker it names still stands (RunAnywhereLLM is undefined at llm.dart:150 — the file never imports runanywhere_llm.dart, and Dart imports are not transitive).

Import RunAnywhereLLM before calling it.

llm.dart calls RunAnywhereLLM.shared.extractStructuredOutput(...), but does not import the library that declares RunAnywhereLLM. Dart imports are not transitive, so this unresolved identifier prevents the Flutter package from compiling.

Use options.structuredOutput.mode before the mode argument, as the other bindings do.

Kotlin, Flutter and React Native all use options.structuredOutput?.mode ?: mode. Swift always uses the mode argument and drops the caller's effective.structuredOutput?.mode. As a result, the same options give a different enforcement mode in Swift, and StructuredResult.mode reports a mode the caller did not request.

The command uses wally, but the prompt and output still say RCLI WORKS. Use a wally-specific value so the example does not retain the removed CLI name.

Use asynchronous parsing for worker-owned models.

When mustUseLlamaBackendWorker() is true, generateCore sends generation to the llama BackendWorker. generateStructured then calls synchronous StructuredOutputProtoAdapter.parse(), which throws because synchronous parsing cannot use the worker. Call parseAsync() and bypass the WASM export check when worker parsing is active.

The same synchronous parse path existed with the previous validationOnly default. This is an existing worker-path failure that the new default also exposes, not a failure specific to constrained decoding.
