## Summary
- `baml.errors.UnknownError.from<T>` and `with_message<T>`: one-call
boundary normalization — pass through a known `T`, unwrap a wrapped `T`,
never double-wrap, else wrap with an optional breadcrumb; plus a
`ToString` impl
- wrapping preserves the original stack trace and cause chain (VM
intrinsic) through rethrows, host boundaries, and GC; VM throw
bookkeeping resets per entry point
- stdlib streaming boundaries declare `throws Failure | UnknownError`
and normalize via `ai.errors.normalize`, now built on `from<Failure>`
- `throws unknown` stays legal everywhere; open contracts are exempt
from E0097 extraneous-throws warnings
## Usage
```baml
// Close an open error channel at a boundary: from<T> passes a real ApiError
// through, unwraps a wrapped one, and wraps anything else exactly once.
function fetch() -> Data throws ApiError | baml.errors.UnknownError {
risky() catch_all (e) {
_ => throw baml.errors.UnknownError.from<ApiError>(e),
}
}
// Or wrap unconditionally with a breadcrumb (T = never):
// throw baml.errors.UnknownError.with_message<never>(e, "fetch failed")
// The wrapper is transparent: catchers see the ORIGINAL throw site and cause.
fetch() catch_all (error, context) {
baml.errors.UnknownError => {
error.data // original thrown value
context.stack_trace // frames from the original throw
context.root_cause().error // walk the cause chain to the root
},
let api_error: ApiError => { /* typed errors arrive typed */ },
}
```
## Issue Reference Fixes #4355 ## Changes - Configure the complete x86_64 and aarch64 musl cross toolchains in each target's existing `matrix._.before` hook. - Pin both toolchain archives to immutable release URLs and verify their SHA-256 digests before extraction. - Explicitly select the target compiler, C++ compiler, archiver, and Cargo final linker so the Ubuntu host linker cannot emit a glibc addon under a musl package name. - Reject musl addons containing `GLIBC_*` symbols or glibc runtime dependencies before upload. ## Root cause The x86_64 musl matrix entry configured `CC_x86_64_unknown_linux_musl=musl-gcc` for C build scripts but did not configure Cargo's final linker. Cargo therefore linked `baml_node.linux-x64-musl.node` with Ubuntu's glibc host `cc`. Ubuntu's lightweight `musl-gcc` wrapper also lacks the musl-compatible dynamic `libgcc_s.so.1` required by this cdylib, so both musl targets now use complete cross toolchains and sysroots. ## Validation - `actionlint .github/workflows/build2-nodejs-sdk.reusable.yaml` - `python3 -m unittest discover -s scripts/tests -p 'test_*.py' -v` (50 tests) - `prek run --files .github/workflows/build2-nodejs-sdk.reusable.yaml --show-diff-on-failure --color never` - [One-off four-cell Alpine validation](https://github.com/BoundaryML/baml/actions/runs/32295180628): for both x86_64 and aarch64, the no-fix controls depended on `libc.so.6` and the glibc loader and failed in `node:22-alpine`; the fixed builds depended on musl's `libc.so` and loaded successfully. The temporary Alpine validation workflow was removed after the successful run and is not part of this PR. `scripts/tests/test_release_pipeline_contract.py` is unchanged from `canary`. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved musl-based Node.js addon builds across x86_64 and aarch64 targets. * Prevented incompatible glibc dependencies in musl addons. * Confirmed addons load correctly on Alpine Linux, including cross-architecture scenarios. * **Tests** * Added automated coverage for native and cross-compiled musl addon builds. * Added checks for ELF compatibility and expected Alpine runtime behavior. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
## Summary - Standardize the C# generator's conventional filesystem directory on `baml_sdk`, matching every other generator. - Update C# fixtures, build consumers, release verification, workflows, documentation, and the website generator output example. - Keep public C# namespaces and legitimate `baml_client` package/module APIs unchanged. Linear: [B-1591](https://linear.app/boundaryml2/issue/B-1591/standardize-c-sdk-generator-output-directory-on-baml-sdk) ## User-visible change With omitted `output_dir`, C# now writes to `../baml_sdk`. A manifest `output_dir` still names the parent, so `output_dir = "generated"` writes to `generated/baml_sdk`. The CLI `--output-dir` override remains the final explicit output path. This is an intentional filesystem path change. There is no automatic detection or migration of an existing `baml_client` directory; projects adopting the new generator output must update their build includes, scripts, and ignore rules as needed. Atomic staging and backup paths follow the new target stem (`.baml_sdk.baml-staging` and `.baml_sdk.baml-backup`). ## Test plan - `cargo test -p baml_codegen_types --lib` - `cargo test -p sdkgen_csharp --lib` - focused `baml_cli` directory-resolution tests for omitted and explicit `output_dir` plus unchanged Python behavior - real CLI generation with omitted and manifest-explicit layouts - C# fixture setup plus `cargo test -p sdk_test_csharp --lib` (15 passed, 1 known ignored; one parallel MSBuild cache collision reran green serially) - `python3 -m unittest scripts.tests.test_release_pipeline_contract` - `actionlint` on changed workflows - `pnpm --dir typescript2 exec biome check app-website/app/baml-intro/_components/try-baml.tsx` - focused `cargo clippy --all-targets -- -D warnings` for every changed Rust/C# harness crate - `cargo fmt -- --check --config imports_granularity="Crate" --config group_imports="StdExternalCrate"` - full `cargo test --lib` passed all relevant crates before the local Python bridge aborted on its missing prebuilt `/install/lib/libpython3.13.dylib` ## Compatibility This is an intentional generated filesystem path change for C#. Public C# namespaces and other legitimate `baml_client` package/module APIs are unchanged. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Standardized generated SDK output across languages and tools under the `baml_sdk` directory. - C# projects, package consumers, and generated-source workflows now use the unified output location. - **Documentation** - Updated generator and C# SDK documentation to reflect the standardized directory. - Removed outdated guidance for the legacy `baml_client` directory. - **Bug Fixes** - Updated C# generation, packaging, verification, and deployment flows to consistently locate generated sources. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
## Summary - add provider-neutral, keyless request preview and prompt-role normalization used to audit generated request shapes without network or credential access - make the generated Python SDK migration-compatible: ignore unknown model fields, optionally default nullable class fields to `None`, type `_types` truthfully, preserve concrete union values, and forward stream cancellation - add typed `FinishReasonError`, invoke-error normalization, configurable agent schema attempts, and streaming Retry/Fallback/RoundRobin behavior - make recursive generic output-format planning finite and sound across direct and public prompt paths, propagating deferred failures as structured `RenderPrompt` errors instead of successful empty schemas - add native total-request and streaming time-to-first-token deadlines for OpenAI Chat/Generic/Responses, Anthropic, and Vertex clients, preserving typed timeout and cancellation semantics ## Why VetRec is replacing the legacy `baml-py==0.223.0` client atomically with the current compiler/bridge/Python SDK. These compiler and runtime primitives close the request, schema, retry, stream, timeout, generated-model, and static-typing gaps required by that cutover. ## Validation at `b992706e9` - Python SDK generator: 129/129, including the Windows-native embedded-source path regression; CLI library: 465/465; combined SDK/codegen checks: 159/159 - provider timeout regressions: 11/11; normal provider streams/defaults: 6/6; raw SSE lifecycle/deadline regressions: 12/12 - affected Rust packages: 181/181 via `cargo nextest` - merged-canary exact snapshot gate: 3,304/3,304, doctests green, no unreferenced snapshots or `.snap.new` files - full BAML aggregate and fresh 247-test LLM group pass, including timeout/disconnect behavior under aggregate load - generated Python Ruff/Pyright/Pytest partitions pass, including reflected `BamlType` tokens and nullable-field omission behavior - SDK parity holds required gaps at 4,457 while increasing present declarations from 2,068 to 2,072 - `cargo build -p baml_cli`, relevant `cargo check`, all-target/all-feature `cargo clippy`, CLI builtin snapshots, `cargo fmt --all -- --check`, and `git diff --check` pass - VetRec source-built consumer proof at this exact revision: 309 BAML files checked, 254 generated payload files, deterministic 257-file / 39,819-symbol output, 5/5 generated boundary tests, and 91/91 isolated artifact-foundation tests This head includes current `canary` checkpoint `1a997de0a` and its local merged-context gates. Its exact-head GitHub rollup is terminal green: 52 successful contexts, 21 skipped, one neutral, zero failures or pending; all 9 review threads are resolved. ## Scope and platform note This is a compiler/runtime PR only. It does not merge to `canary`, publish artifacts, merge VetRec, or deploy anything. The new request and TTFT deadlines are enforced on the native/Python server path used by VetRec. `bridge_wasm` accepts the generated SSE arguments but does not enforce deadlines, matching the existing browser-fetch timeout limitation; `sys_wasm` SSE remains unsupported. <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **High Risk** > Large changes to core AI client boundaries—auth preview, error taxonomy, streaming retry semantics, and timeouts—affect every provider invocation and migration-sensitive behavior. > > **Overview** > Adds **credential-safe request preview** across the AI client stack: `Client.render` and `FunctionSpec.build_request` build provider HTTP shapes without I/O, using preview-only media resolution, placeholder auth, and `PreviewUnsupported` when a preview would require file reads or URL fetches. > > **Invoke and streaming errors** are tightened with closed `InvokeError` / `RaisedInClient` types, explicit `normalize` classification (infrastructure errors map to typed failures), `FinishReasonError` for non-complete stop reasons, and `normalize_invoke` at invoke boundaries.

… = "language"` is used for SDKs (#4526) ## Summary - centralize the naming convention implemented by every generator target - require `language` for Go and C#, and require `preserve-case` for every other output type - report a span-aware `E0019` diagnostic pointing at `baml.toml` before unsupported settings reach or are ignored by a backend - document the per-target naming convention contract ## Root cause The CLI parsed both naming conventions as globally valid but did not validate each backend's target-specific capability before dispatch.

## What this adds Copies of the Linux CI lanes pointed at ix machines, running side by side with the gating Blacksmith checks, plus one reconcile workflow. ## How the machines work Machines exist per job. A queued ix-labeled job gets a fresh VM, forked copy-on-write from its lane's seed - a disk snapshot of the machine that last ran that lane green on canary - runs that one job, and is deleted. Green canary runs refresh the seeds. Warmth is the forked disk itself: checkout, `target/`, `node_modules`, toolchains are already there. Everything about the fleet (lane sizes, region, autoscaling dials) lives in [indexable-inc/ix-runners](https://github.com/indexable-inc/ix-runners), versioned by the single commit pin in `ix-runners.yml`. ## Where secrets live - A job machine's only credential is its single-job runner registration which dies when the job ends. - `IX_TOKEN` is read only by `ix-runners.yml`, which runs on GitHub-hosted runners on schedule/dispatch/workflow_run - triggers that register from the default branch only, so PR code never executes with it. - Fork PRs never reach ix; they keep the hosted fallback lanes they have today. ## Setup Set `IX_TOKEN` in Actions secrets, install the ix-runners GitHub App, merge. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **CI Improvements** * Added preview CI workflows for Linux, WASM, webview, SDK, documentation, and platform-specific testing. * Improved build reliability with caching, retry handling, artifact collection, and cross-platform coverage. * Added automated runner-fleet reconciliation and workload-specific runner routing. * Introduced a non-blocking size-gate trial with consolidated platform reports. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
A parent BAML VM spawning many short-lived children can keep GC waiting while allocation spending grows far beyond its budget. This adds a safe collection checkpoint after spawn setup and preserves GC polling progress across VM re-entry. ## Issue Reference Next layer above #4844 (`codex/gc-idle-cleanup`). ## Changes A workload that starts all its children before awaiting their results exposes the problem: ```baml while (i < count) { jobs.push(spawn { Work(256) }); i = i + 1; } for (let job in jobs) { sum = sum + (await job); } ``` **Before:** each spawn returns from `BexVm::exec()`, and re-entry resets the GC polling counter. Repeated short executions can therefore avoid reaching the polling interval. Tokio can also suspend spawn setup while the parent still holds its heap permit, leaving a requested collection waiting for that parent. **After:** the polling counter carries across re-entry and resets when it actually polls. After each successful spawn, the engine checks allocation pressure and, on native targets, the park-request flag. If either requests GC, it enters the existing `gc_safepoint` path to release its permit, collect or cooperate with another collector, and reacquire before resuming. The checkpoint is after child registration, after the future is pushed onto the parent's GC-tracked stack, and after the futures-registry guard is dropped. Both parent and child roots can therefore be forwarded by moving GC. With neither pressure nor a park request, spawn continues without renewing its permit. This uses the existing collection policy; it adds no Tokio hooks or CPU timeslicing. ## Testing Rebased the full four-PR stack onto `canary` at `bd85ce9de`. On the combined result, **271 tests passed** with `heap_debug,gc_profiling` in `fasttest`: 126 engine unit tests, 100 heap unit tests, 36 VM unit tests, and 9 allocation-budget integration tests. Full native workspace Clippy and the WASM Clippy task passed. The production patches rebased unchanged; the spawn regression now creates object-slot pressure. Historical measurements from the initial implementation (`a303df192`), before rebasing onto the updated slot-only allocation policy and work-guard lifecycle. These numbers do not measure the rebased stack. Paired native repro runs, four Tokio workers, optimized builds with `gc_profiling` and without `heap_debug`. Each child retains 256 three-integer arrays until returning; the parent retains the child futures. Execution time excludes source compilation; RSS is the whole process peak. These are individual paired measurements, not a throughput guarantee. | Workload | Before | After | | --- | --- | --- | | 10,000 allocating children | 752 MiB; 2.116 s; 1 full GC | 299 MiB; 2.116 s; 16 full GCs | | 50,000 allocating children | Stopped by the 1 GiB RSS guard | 314 MiB; completed in 12.273 s; 81 full GCs | | 10,000 children with no array elements | 0.145 s; 0 GCs | 0.145 s; 0 GCs | The single-worker allocating case also completed with lower RSS (747 → 295 MiB). With explicit full-GC requests every 10 ms, the 50,000-child case completed at 315 MiB with 629 collections; the original hit the RSS guard while a collection was waiting. Frequent explicit collection took 19.962 s, versus 12.273 s with automatic triggering. - 105 selected tests passed with heap safety checks enabled: VM unit tests, allocation budget, cancellation, task groups, detached work, finalizers, early yielding, and GC during future operations. - Added regressions for polling across engine handoffs and collection after spawn while preserving captured values and the future handle. After rebasing, the spawn test imports enough short-string objects to exceed the slot budget; it no longer relies on large string backing storage to trigger GC. - Native Clippy for all targets of `bex_vm` and `bex_engine` passed with warnings denied; WASM engine compilation passed. The commit hooks also passed formatting and full-workspace Clippy with all targets and features. GC can now make progress through the reproduced spawn burst. Live children and retained futures still consume memory; this is not a hard RSS bound. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved memory management during concurrent task creation, helping garbage collection run reliably under allocation pressure. * Preserved garbage-collection polling progress when execution switches between engine handoffs. * Improved stability when processing large text allocations and spawned computations. * **Tests** * Added coverage for garbage collection during task spawning and continued polling across repeated execution steps. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
## Summary Naming-only refactor of the agreed profiling types: - `RawRecord` -> `Marker`; function variants -> `FunctionEnter`, `FunctionExit`, `FunctionExitAwaited`. - Thread variants -> `BexThreadStart`, `BexThreadStartSpawned`, `BexThreadEnd`; `SetFunctionId` -> `SetBoundaryLocalId`. - Ring types -> `OSThreadMarkerRing`, `OSThreadMarkerRingSegment`, `OSThreadMarkerRingHandle`. - Decoder types -> `CallDecodeState`, `BexThreadDecodeState`, `ExecutionDecodeAccumulator`. - Update references, tests, and documentation; record open design concerns in `documents/profiling-design-concerns.md`. Wire tags, payload layouts, and behavior are unchanged. Calling-context, evidence, publication, and reader types are not renamed. ## Validation - Rust 1.98.0: `cargo test --locked --no-fail-fast -p bex_prof_store -p bex_events -p bex_vm -p bex_engine -p baml_query_profiles -p baml_lsp_server` - 735 tests passed, 0 failed, 4 ignored across these six crates. - Rustfmt parsing/format checks passed for all changed Rust files. - Reference scan and wire tag/size constant comparison passed. - `git diff --check` passed. macOS linker warnings about large unwind tables were non-fatal. The first build was blocked by an untrusted mise shim; the successful run used system tools instead. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Refactor** - Standardized profiling terminology across runtime, storage, virtual-machine, and event-processing components. - Updated profiling event, thread lifecycle, ring, and decoding names without changing behavior, data formats, or semantics. - **Documentation** - Updated profiling specifications and implementation notes to reflect current terminology. - Added a document outlining open profiling design considerations. - **Tests** - Updated profiling test coverage to use the standardized terminology while preserving existing assertions. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

- Implements F2 LSP rename. Note there are still some positions where rename is still not supported. For example, interface fields cannot be renamed as implicit field links would break on a pure rename. - Added a unified way to classify generated, companion, and stdlib internal items which is used in various contexts (such as completion and `baml describe` lists) to decide whether to show them. This includes hiding `_`-prefixed stdlib items unless the user actually wrote `_`. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added rename support in the BAML language server, including preview, cross-file updates, validation, and safeguards for read-only or unsupported symbols. - Improved go-to-definition, symbol usage tracking, and token highlighting for interface projections, optional access, qualified paths, bindings, and parameters. - Added more precise completion behavior, hiding standard-library internals by default while revealing them when explicitly requested. - **Bug Fixes** - Improved package and namespace listings to consistently filter internal symbols. - Refined built-in type and member completion suggestions. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Uploads JUnit reports to [Trunk Flaky Tests](https://docs.trunk.io/flaky-tests) so intermittent failures are tracked per test rather than per red job. Inert until a `TRUNK_API_TOKEN` repository secret exists — without it every upload step skips itself. ## Collections One test run uploads to exactly one collection, so the boundaries follow the jobs. | Collection | Contents | Jobs | | --- | --- | --- | | [baml-language](https://app.trunk.io/boundaryml/flaky-tests/collections/jgs6yJXj) | The `baml_language` cargo workspace, including snapshots and CLI | `cargo test` ×3 platforms, `snapshot tests` | | [sdk-conformance](https://app.trunk.io/boundaryml/flaky-tests/collections/9AZXu27s) | The `sdk_test_*` legs plus `baml_bridge` | `sdk tests` | | [editor-frontend](https://app.trunk.io/boundaryml/flaky-tests/collections/xl5LO9gK) | `app-vscode-webview`, `pkg-grammar`, its highlight.js port | `Webview Tests`, `Grammar Tests` | | [developer-docs](https://app.trunk.io/boundaryml/flaky-tests/collections/aDqMrNXq) | `app-developer-docs` | `Developer Docs` | ## Job gating changed 1. For now, quarantining is disabled in Trunk. You can change this setting at the links above. 2. Forks upload nothing and don't take advantage of quarantining. Let us know if that's a priority for you. 3. Right now, with quarantining disabled, the existing exit code will be returned, based on the presence of test failures. 4. Once quarantining is enabled, the exit code will reflect the presence of unquarantined test failures. 5. If no junit files are generated, the exit code will be 1. ## File paths Trunk uses a test's file for CODEOWNERS and for flaky-test fix investigations, and it is part of a test's stable identity, so I've added normalization to enrich the junit output files when the test reporter doesn't set it natively: - **vitest** sets `root` to the repo so `file` comes out repo-relative rather than package-relative, plus `addFileAttribute: true`. No post-processing. - **nextest** cannot emit a file at all: libtest never tells it which source a test came from, so there is no config option and `cargo nextest list --message-format json` carries no path either. `.github/scripts/junit-normalize.py nextest` resolves it per test binary against `cargo metadata` (`baml_tests::interfaces` → `crates/baml_tests/tests/interfaces.rs`). Exact for integration suites; a lib suite lands on the crate's `lib.rs`. - **node:test** emits `<testcase>` with no `<testsuite>` wrapper, which Trunk parses as **zero tests while still reporting the file valid**. The same script groups them by file. ## Not covered `pack_e2e` and `exit_code_e2e` stay on `cargo test`, and `wasm-pack test` and `tree-sitter test` emit no JUnit. Each `sdk_test_*` fixture gate is one Rust test shelling out to a whole foreign suite, so `sdk-conformance` tracks the gates rather than the assertions behind them. `editor-frontend` covers only what CI runs today — `pkg-playground`, `pkg-editor`, `pkg-lsp`, `pkg-proto`, `app-vscode-ext` and `app-website` have `test` scripts that no workflow invokes. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added automated JUnit test-result uploads to Trunk Flaky Tests across supported CI suites. * Added source-file details, improved report organization, and separate reporting for standard, bridge, and CLI end-to-end tests. * Added CI failure reporting and gating when test results cannot be uploaded. * **Documentation** * Added guidance for flaky-test uploads, supported collections, and reporting considerations. * **Chores** * Added generated JUnit files to repository ignore rules. * Improved CI test reporting and result handling. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 5 (1M context) <[email protected]>
…e_prepared (#4874) Reimplementation of #4810, but without the unnecessary defense-in-depth changes (#4872 was accidentally merged into a branch, not canary). Every "bug" that the coding agent found was mostly a red herring and only triggerable by misusing the CFFI API - in a way that going through baml_sdk prevented - so redo the PR while abandoing those changes.

## Changes
Add `/examples/vision`, a runnable Canary guide for readers who want to
ask questions about images or extract typed data from them. It includes
downloadable receipt images and one complete BAML source file.
The guide starts with a concrete client and an image argument:
```baml
client Vision = openai.ResponsesClient.new(
model = "gpt-4.1-mini",
api_key = env.OPENAI_API_KEY,
);
```
Readers then learn to mix text and images, pass labeled image arrays
directly or with a prompt loop, load URL/file/base64 inputs, and return
a typed `Receipt`. Annotations explain role boundaries, image
interpolation, and how `ctx.output_format()` derives prompt instructions
from the return type.
Provider tabs demonstrate OpenAI, Anthropic, and Google. Calls override
the provider with `read_receipt(photo, client = model)`. The page also
covers compatible endpoints and a complete custom `ai.Client` for
Cloudflare's native vision API, followed by a Discord invitation for
stdlib contributions.
Supporting docs changes add provider tabs and left-side annotation
marks, and allow annotation sources outside the errors chapter. No
compiler or standard-library changes.
## Testing
- Docs tests: 47 passed; the database integration test was skipped
locally because its database URL is unset.
- `pnpm lint`, `pnpm typecheck`, and `pnpm build` passed, including
compiled stylesheet validation.
- The full canonical snippet catalog passed validation with Canary.
- Nine native BAML tests passed, including preservation of label/image
order and custom-client request/response handling.
- Local mock HTTP checks verified actual PNG payloads for both
labeled-array forms, file and URL input through the custom client, typed
receipt output, and malformed/error responses.
- Checked the page, provider tabs, and annotation views in the browser.
The downloadable source compiles independently.
Live model inference was not tested; it requires provider credentials.
The Cloudflare example explicitly documents its single-image,
single-turn, non-streaming scope.

Readers following the getting-started, TypeScript bridge, classifier, and receipt tutorial could encounter outdated APIs or incomplete setup instructions. The guides now use runnable Canary examples: `baml_sdk/index.js`, generated `_async` exports, concrete provider clients, and the current streaming API. The concurrency chapter now provides a tested CLI simulation and accurately describes error propagation. Audited all 18 authored pages, with a page-by-page decision and verification limits in `typescript2/app-developer-docs/DOCS_AUDIT.md`. The crawl defaults to authored content. Live provider inference remains unverified without credentials; request construction, fixture parsing, and SDK calls were tested with local mocks. The audit also found `$stream` reference URLs returning 404 and section IDs colliding with member IDs. Normalize encoded route segments, preserve member permalinks, and render docstring headings below the page title. Preserve `throws never` in signatures and release idle serverless database connections. The HTTP job resolves and verifies a release stored in its configured database, instead of assuming the public site and CI have identical data. Getting started now includes installation and PATH setup for macOS/Linux, Windows, and Arch, plus editor setup and updates. The TypeScript guide starts with a synchronous call and introduces `_async` afterward. The aggregate job now reports the required `Developer Docs` name and runs for merge groups. Merge-group change detection uses the base/head diff, and an unreadable diff fails instead of silently skipping checks. Regression tests cover those cases and failure propagation. Compile-only snippet validation skips disposable bytecode caches and reports progress per snippet; execution tests retain normal compilation. Validation: - All 33 snippet targets, 34 project behavior tests (including nine vision tests), and four inferred-signature checks pass on Canary. - Actual generated Node SDK examples typecheck and run; classifier, receipt extraction, and streaming pass with a local HTTP provider mock. - 53 app tests pass, including database integration; lint, typecheck, production build, and compiled-style checks pass. - Production-mode crawl of all 18 authored pages and 43 linked destinations/assets passes. Mobile navigation, annotations, and syntax-highlighted source toggling checked visually. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Refreshed getting-started guidance with installation options, project creation, CLI commands, editor support, and coding-agent setup. * Updated TypeScript bridge guidance for generated SDKs, synchronous/asynchronous APIs, streaming, and type mappings. * Revised examples and tutorials with current naming, setup steps, API-key requirements, and generated clients. * Clarified concurrency, error handling, functions, CLI usage, and language-reference guidance. * Improved generated reference pages with stable anchors, correct headings, and preserved error contracts. * Added guidance for currently unavailable cloud services. * **Quality** * Added broader documentation audits and validation for links, headings, snippets, routes, duplicate anchors, and release content. * Improved documentation workflow checks for merge queues, release versions, and production pages. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Implements a unified way to model and analyze memory effects. We previously had more of an ad-hoc list of rules that relied on implementors remembering to update it whenever instructions changed; we now have a more principled resource-based system. - Cells now have and explicit `Place::Deref` in the MIR to explicitly model them instead of using a separate pass. - Cells are now created at the declaration point instead of at the start of the function: previously, two iterations of a loop would share the same cell even if the cell's declaration was inside the loop. - Using the new memory effect model, fixes [B-1698](https://linear.app/boundaryml2/issue/B-1698/stackification-bug-with-closure-dependency-model), an issue with cross-block rematerialization of cell reads <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Fixed captured-variable behavior in closures, including updates across branches, calls, spawned tasks, and loop iterations. * Ensured loop bindings retain distinct values for each iteration, including `continue` scenarios. * Corrected writes to captured fields and bindings so results are preserved. * Improved generic interface dispatch when type information comes from interface arguments. * Fixed optimization and short-circuit evaluation cases involving captured values and nullable data. * **Tests** * Added coverage for closure captures, loops, garbage collection, dispatch, and optimization regressions. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

## Summary - Run nightly candidate selection through one Python invocation; the workflow no longer coordinates primary and fallback snapshots. - Query the 100 most recent `ci.yaml` workflow runs without branch, event, status, or date filters, then filter branch and event locally. - Always query CI independently for each of the 10 newest canary commits from git log using 10 parallel requests. - Prefer the recent-runs result and use the per-commit result only when the primary result is missing or stale; reject partial fallback batches. ## Root cause The failed nightly dispatcher queried 1,000 runs through a heavily filtered `gh run list` request. GitHub returned an internally consistent but stale window whose newest entry was from September 4, while the candidate commits were from September 14. The selector correctly rejected 80 missing commit runs, leaving `source_sha` unset; the Slack notification rendered that as `no candidate commit`. The same broad query also failed with an HTTP 504 on page 5 on September 13. ## Validation - `python3 -m py_compile tools/baml_nightly_select.py` - `actionlint .github/workflows/nightly-release.yml` - `ruff check` and `ruff format --check` for the tool - Live combined invocation against a fresh depth-10 canary checkout fetched 100 CI runs, queried 10 commits in parallel with zero errors, and selected canary head through CI run 35039226385. - Earlier forced-fallback validation with the primary source absent queried all 10 commits successfully and selected the same eligible canary source.

When sending the Friday morning release reminders, post them in the same thread as the Thursday afternoon notification.
## What changes Compiler-backed documentation checks now run in the main BAML pipeline. A compiler change builds one optimized CLI for the compiler suites and documentation examples, instead of Developer Docs building a second unoptimized CLI. Changes to examples or their displayed inferred signatures still validate those examples; a CSS/component-only docs PR no longer starts a Rust build. - Extract the existing compiler/CLI/snapshot job into a reusable workflow. Cargo CI calls it with compiler tests enabled; documentation-only changes call the same workflow with just the CLI build and example checks. These paths are mutually exclusive. - Move snippet compilation, expected-diagnostic checks, behavior tests, and inferred-signature assertions into that workflow. Use the existing 16-vCPU compiler runner and opt-level 1, and share a job-local, compiler-keyed BAML cache across executable examples. - Remove the separate package-boundary invocation: `baml_cli/tests/baml_corpus.rs`, already run by the compiler suite, executes the full corpus including `root.compiler.mounted_interface_diagnostics`. - Keep authored-content, annotation/source consistency, navigation, website quality, database, and SSR/HTTP checks in Developer Docs. Remove compiler-only paths from its change detector. - Gate the docs-only compiler path through `CI-v2 Failure Alert` and the release prerequisites. Preserve the `Developer Docs` required check for site validation. Use the merge-group base SHA when detecting changes in main CI. ## Validation - Exercised the actual change-detection and site-gate shell scripts in a temporary Git repository: 32 scenarios covering PR/merge-group events, compiler/example/signature/style/component/validator/lockfile/workflow changes, main/canary routing, manual dispatch, fork PRs, and failed prerequisites. Verified the two compiler paths are mutually exclusive and both are covered by the required main gate. - `actionlint` passes for the extracted compiler workflow, Cargo workflow, and Developer Docs workflow. Main CI has no new diagnostics; its existing custom `codspeed-macro` label, summary-shell warnings, and commented-out `miri-tests` reference were excluded for the check. - `git diff --check` and commit hooks passed. - Updated the existing workflow contract tests for site-only gating. Local docs tests: 52 passed, 1 database integration test skipped because its database URL was unset. CI's dedicated database integration job passed on the first run. ## Measured CI result The first compiler/documentation job [passed in 5m41s](https://github.com/BoundaryML/baml/actions/runs/35151567195/job/104981073882), including the compiler build and 1,564 compiler/CLI tests. Both this run and the [earlier Developer Docs run](https://github.com/BoundaryML/baml/actions/runs/35054123799/job/104660659162) validated all 33 snippets, 34 behavioral tests, and four inferred signatures. | Documentation work | Previous workflow | New workflow | | --- | ---: | ---: | | Compile 33 snippets | 3m01s | 10s | | Execute behavior and signature checks | 13m11s | 5s | | Separate package-boundary corpus invocation | 5m02s | Removed; covered by the main corpus test | | Separate CLI build | 2m18s | Reuses the compiler test build | Documentation adds about 50 seconds to the shared job including Node setup. These are observed CI timings on different runs and runner configurations, not an isolated microbenchmark or a guarantee of total merge latency. The docs-only CLI path has been checked locally for routing but has not yet been timed on GitHub. The first site run caught two tests asserting the old workflow ownership. Commit 0dff2e5 updates those expectations. Its Developer Docs gate passed, and the compiler/documentation job passed again in 5m39s (9s snippet compilation plus 6s behavior/signature checks).
An app that has the user determine whether a sample BAML program is valid or not to assist them in developing a stronger intuition for the BAML type system. Each puzzle is procedurally generated using the type system's axioms and/or likely misses. Since, like with fuzzers, a uniformly random system would produce almost exclusively unhelpful "boring" puzzles, the system is designed to adaptively adjust complexity/difficulty combined with the principles utilized in the puzzle based on the user's past responses to optimize learning. If provided an openai/anthropic key, a mode can be enabled where the user responds with the reason they think a puzzle's program is invalid which will be scored against the correct answer by an LLM which also provides feedback (if the user thinks a program is valid, no explanation will be requested as there are no contrapositives to explain). <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added a browser-based BAML type-system quiz with adaptive practice and mastery modes. - Added compiler-backed questions, explanations, scoring, progress tracking, save slots, and transcript export. - Added syntax highlighting, in-browser formatting, optional AI reasoning feedback, and provider-specific settings. - Added resilient browser storage and combined quiz/site publishing. - Judge API keys are kept per browser tab and cleared when the tab closes. - **Tests** - Added automated coverage for quiz behavior, persistence, formatting, compiler verification, and browser workflows. - **Documentation** - Added user and development documentation for the quiz and publishing workflow. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

On Windows, only respect USERPROFILE and ignore HOME. On all OS's, ignore `BAML_HOME=""` - we can't do anything meaningful with that value. Original contributor PR description: **Problem.** On Windows, PowerShell often has `HOME` unset or set to an empty string, while the real home is `USERPROFILE`. `baml_home()` treated a present-but-blank `HOME` / `BAML_HOME` as configured, so it never fell through to `USERPROFILE` and resolved `~/.baml` against the current working directory. The wrapper's project walk-up only stopped at `$HOME`, so a missing/blank `HOME` continued to the drive root and could pick up a stray `C:\baml.toml`. Path selectors also expanded `~/…` but left `~\…` relative to the declaring directory. **Fix.** Treat empty or whitespace-only env values as unconfigured in the shared `baml_home()` / `user_home()` helpers. Use that home for walk-up, and expand `~\` the same way as `~/`. `~alice` is still not expanded. **User impact.** Windows and CI setups with a blank `HOME` get toolchain state, project `baml.toml` discovery, and `~` path selectors under the real user home instead of cwd / drive root. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved how the application determines its BAML home directory. * Honors a configured `BAML_HOME` location when provided and falls back to the user’s home directory. * Handles empty or unavailable home-directory settings more reliably. <!-- end of auto-generated comment: release notes by coderabbit.ai --> Co-authored-by: Sam Lijin <[email protected]>
