What

Runs the decision checkpoints on-device through wally decisions, behind the same request/render contract as the hosted path.

  • Two transports, one contract. --local (or a -m that resolves to a local decision artifact) scores in-process through the kit's rac_decision_* component (ABI v13, shipped in cpp-desktop-v0.20.38-2) and maps the proto result back onto the same DecisionsResponse the cloud transport renders; --cloud forces the hosted path. Human output and --json are transport-identical.
  • Catalog rows follow the existing dual-backend convention. clef-flash-9b (GGUF / llama.cpp) and mlx-clef-flash-9b-4bit aliased clef-flash-mlx (MLX, Apple). One merged models list row, like qwen3-0.6b. Decision is the only non-Language category the LLM-only cut surfaces (is_llm widened to Language | Decision, mirrored in cmd_list's row filter).
  • label_mass stays a cloud-only field. The local head has no whole-distribution mass to report, so the value is omitted (0.0 + renderer told it is absent) rather than faked, and the low-fit note does not print locally.
  • The 403 model_not_entitled message no longer says "log in again". Entitlement is account-level; re-login cannot change the answer. It now points at the local checkpoints instead.

Verification

  • Real GGUF end-to-end through the installed binary: yes 93.6%, billing 95.3%, urgency 1.836 — matches the oracle fixture. MLX path: yes 93.9%, billing 93.9%.
  • wally models pull clef-flash-9b downloads from the right URL; clef-flash-mlx / mlx-clef-flash-9b resolve to the MLX build.
  • 394 lib tests, golden corpus (4 cases re-captured: decisions help x2, models list x2), test_wally_unit 50/50, test_decisions_cli, test_versions, test_retired_model_ids, test_contract_sync; clippy --all-targets clean.

Notes

Update: MLX path verified against the published release

The Apple host now pins the SDK at v0.20.38 (sdk_ci_ref + both workflow checkouts). Verified by building the MLX host from a clean v0.20.38 checkout with the published binaries and scoring the canonical ticket through --local:

yes 91.4%   billing 92.8%   urgency high 86.7%

The tag carries the decision callback (callbacks.decision = mlxDecision, ClefDecisionModel) and the release's RunAnywhereMLXRuntime archive exports it. sdk_package_version stays 0.20.37 because that pin is the release-dist fallback (runanywhere-swift has no 0.20.38 tag yet); Wally CI builds from sdk_ci_ref, not the dist repo.

Kit pinned to the fixed -3

The -2 Linux x64 kit bundled a sherpa-onnx-c-api.so requiring GLIBC 2.38, above Wally's 2.35 floor, so linux failed to link. cpp-desktop-v0.20.38-3 rebuilds sherpa on the 22.04 floor (verified: max GLIBC 2.34) and this branch pins its five SHAs, re-verified against the release sidecars.

Summary by CodeRabbit

  • New Features
    • Score decisions locally with supported models, including offline, or use hosted scoring with wally decisions --cloud. Without a mode flag, the command selects local scoring for recognized local models and hosted scoring otherwise.
    • Browse decision models in the catalog and use the same request options and output formats for local and hosted scoring.
    • For offline scoring, pull the model before use. The clef-flash-9b GGUF model works across supported kits; the MLX version requires Apple MLX support.
  • Bug Fixes
    • Updated the account-access message to explain when a model is unavailable and suggest local scoring as an alternative.

Regenerated src/sys/bindings.rs from the 0.20.38-2 kit headers: adds the
rac_decision_* C ABI (124 declarations) and renames the engine vtable's
reserved_slot_5 to decision_ops, mirrored in the local fake_llm fixture.
One contract, two transports. --local (or a -m resolving to a local decision
artifact) scores in-process through the kit's rac_decision_* component and
rebuilds the same DecisionsResponse the cloud transport renders; --cloud
forces the hosted path. The kit pin moves to cpp-desktop-v0.20.38-2 and the
bindings are regenerated for ABI v13 (decision_ops in the vtable).

Catalog: clef-flash-gguf and clef-flash-mlx-4bit, the only non-Language rows
the LLM-only cut surfaces (is_llm widened to Language|Decision, mirrored in
cmd_list's filter). label_mass is reported only on the cloud transport; the
local head has no whole-distribution mass to give.

Verified with the real GGUF: yes 93.6%, billing 95.3%, urgency 1.836.
…t entitlement message

Catalog rows follow the dual-backend convention: clef-flash-9b (GGUF,
llama.cpp) and mlx-clef-flash-9b-4bit aliased clef-flash-mlx, one merged
models list row, all three spellings resolve. Decision is the only
non-Language category the llm-only cut surfaces.

The 403 model_not_entitled message no longer sends anyone to re-login:
entitlement is account-level, so a new session cannot change the answer;
it now points at the local checkpoints instead.

📝 Walkthrough

Walkthrough

This change adds local Clef Flash decision models and SDK decision-scoring interfaces. The wally decisions command supports local and hosted scoring through shared response rendering. Offline model handling, catalog output, documentation, and tests are also updated.

Changes

Local decision scoring

Layer / File(s) Summary
Decision ABI and SDK interface
src/sys/bindings.rs, scripts/build/sys-bindings.h, tests/local_harness/fake_llm.rs, versions.toml, tests/golden/expected/version*, .github/workflows/*
Adds decision types, callbacks, service and component APIs, and ABI checks. The engine vtable assigns decision operations to its former reserved slot. SDK pins and expected IDL versions and hashes are updated.
Decision model catalog and discovery
src/catalog/catalog.rs, src/catalog/model_ref.rs, src/commands/cmd_list.rs, src/commands/model_labels.rs, tests/golden/expected/local__backends*, tests/golden/expected/local__models*
Registers GGUF and MLX Clef Flash decision models. Catalog filtering, model grouping, and category labels now include Decision entries. Expected backend and model listings include the new decision support.
Local and hosted CLI scoring
src/commands/cmd_decisions.rs, src/bootstrap.rs, src/commands/model_setup.rs, src/account/console.rs, tests/test_decisions_cli.py, scripts/test/smoke-mlx.sh, tests/golden/expected/help__*, README.md, docs/MODELS.md, AGENTS.md
Adds local/cloud selection, local request and result conversion, runtime execution, and shared output rendering. Offline mode skips telemetry and authentication initialization and prevents automatic model pulls. CLI examples, smoke coverage, account messaging, and documentation are updated.

Review details

Systems and components

  • observed — src (service) was modified; 9 changed files map to changed impact.
  • observed — tests (service) was modified; 11 changed files map to changed impact.
  • observed — scripts (service) was modified; 2 changed files map to changed impact.
  • observed — AGENTS.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in AGENTS.md: Documents cloud and local transports for wally decisions, both mapped to DecisionsResponse for shared rendering and JSON output. Identifies the two local decision models and their inclusion in the LLM-only catalog cut.
  • observed — Modified behavior in README.md: Added instructions for pulling and running the local Eve checkpoint with wally decisions --local -m; the text describes --local or a local -m as selecting in-process SDK scoring, --cloud as forcing hosted scoring, and states that both transports share request flags and output formats.
  • observed — Modified behavior in docs/MODELS.md: Documents that decision models return label probabilities rather than generated text, directs users to wally decisions or its wally decide alias, and lists supported question formats and help forms. This guidance was previously combined with the hosted-model description.
  • observed — Modified behavior in docs/MODELS.md: Replaces the statement that eve is hosted-only with a description of it as the hosted default, adds two local checkpoints with backend and pull details, and documents local-selection behavior, offline operation, and platform/runtime availability.

- Around line 4503-4546: Set the name on both `CatalogEntry` variants with merge
key `clef-flash-9b` to the same backend-neutral display name, so merged output
does not depend on which backend is preferred; update both golden files to

Review comments at @src/commands/cmd_decisions.rs:
- Around line 766-768: Update the DecisionResult match so only proto_rc ==
sys::SUCCESS returns a parsed result; remove the non-empty-answers success path
and report the failure with out::error_line when proto_rc is unsuccessful,
preserving a non-zero command exit.
- Around line 533-548: Update model_resolves_locally to check the stored
category for registered non-catalog IDs and return true only for Decision
models. Keep filesystem paths on their existing local path without applying that
category check, since register_local_path assigns them Language by default.
- Around line 692-715: Update run_local to initialize through a bootstrap path
that skips Phase 2 network operations, including telemetry registration, while
preserving local initialization and filesystem discovery. Keep the existing
bootstrap behavior for non-local commands.

The tag carries the decision callback (callbacks.decision = mlxDecision),
so the MLX path can score local decision models. Verified by building the
MLX host from a clean v0.20.38 checkout and scoring the canonical ticket
(yes 91.4%, billing 92.8%, urgency 86.7%).

sdk_package_version stays 0.20.37: that pin is the release-dist fallback
(runanywhere-swift), which has no 0.20.38 tag yet. sdk_ci_ref is the
checkout Wally CI actually builds from.

The -2 Linux x64 kit bundled a sherpa-onnx-c-api.so requiring GLIBC_2.38,
above the 2.35 release floor, so the linux job failed to link. The -3 kits
rebuild it on the 22.04 floor (verified: max GLIBC_2.34). Apple kits are
rebuilt too; all five SHAs come from the published -3 release and were
re-verified against their sidecars.
The release tags on runanywhere-sdks are not protected or immutable, and
this checkout supplies the Swift code compiled into the Apple bottle, so a
retargeted tag would change what ships. The SHA is what v0.20.38 resolved
to when this pin was made (CodeRabbit security finding on #168).

- model_resolves_locally: a registered non-catalog id must store the Decision
  category before Auto sends it local; an HF-pulled LLM registered earlier
  would otherwise reach the decision component and fail at load. Paths stay
  accepted (register_local_path labels them Language by construction).
- --local now bootstraps offline: the SDK's telemetry/auth phase posts
  anonymous telemetry to the staging backend in development, which broke the
  documented no-network promise. Registrations (backends, catalog, model
  paths) still run; downloaded-model discovery still works (verified with a
  dead base URL).
- A non-success decide rc with partial answers now fails instead of printing
  some answers and exiting 0; every requested question must carry an answer.
- The merged clef row carries a backend-neutral name ('Clef Flash 9B
  (decision)'): the name came from the MLX variant while the pull id and size
  came from GGUF, so the listing read as MLX while pulling llama.cpp.

Autofix skipped. No unresolved review comments with fix instructions found.

CodeRabbit round 2:
- ensure_model_ready refuses to pull when options.offline is set, so
  'wally decisions --local' cannot start a download behind its no-network
  promise (rc 1, names the pull command to run).
- Transport selection now probes the registry through an offline bootstrap
  (refresh_registry restores manifest entries) instead of reading an empty
  in-memory registry before bootstrap ran. Catalog rows, paths and known
  hosted ids still answer without initializing the SDK; a registered
  non-Decision id keeps going to the hosted transport.
catalog::find filters MLX rows by host OS, so off-macOS 'clef-flash-mlx'
correctly does not resolve locally. The test asserted Ok(true) everywhere
and failed linux/windows/windows-arm64 in CI.
clef-flash-9b is filtered by wally_has_llamacpp: the commons-only Windows
ARM64 kit has no engine, so the row correctly does not resolve there. The
test asserted Ok(true) unconditionally and failed that job.
