8-12: Consider adding workflow status check.The workflow will run even if the upstream
prophet-wasmstanworkflow fails. Consider adding a condition to check the workflow status.on: workflow_run: workflows: - prophet-wasmstan types: - "completed" + if: ${{ github.event.workflow_run.conclusion == 'success' }} branches: - main.github/workflows/wasmstan.yml (2)
32-35: Consider adding versioning to the artifact name.The artifact name is currently static. Consider including version information or a unique identifier to distinguish between different builds.
- uses: actions/upload-artifact@v4 with: - name: prophet-wasmstan.wasm + name: prophet-wasmstan-${{ github.sha }}.wasm path: components/cpp/prophet-wasmstan.wasm
32-35: Consider adding artifact retention settings.The upload-artifact action supports retention settings which can help manage storage usage.
- uses: actions/upload-artifact@v4 with: name: prophet-wasmstan.wasm path: components/cpp/prophet-wasmstan.wasm + retention-days: 90crates/augurs-prophet/src/lib.rs (1)
16-17: LGTM! Consider adding module documentation.The new
wasmstanmodule follows the established pattern of feature-gated optimization backends. The implementation looks clean and well-organized.Consider adding a doc comment before the module declaration to explain its purpose and usage, similar to the comment above the
optimizermodule:#[cfg(feature = "wasmstan")] +/// WebAssembly-based Stan optimizer implementation. +/// This module provides optimization capabilities through WebAssembly, +/// enabling Stan models to run in WebAssembly environments. pub mod wasmstan;crates/augurs-prophet/Cargo.toml (1)
53-57: Feature flags are well-structured but could use additional documentation.The feature flags follow a consistent pattern with the existing cmdstan implementation and have correct dependency chains. However, consider adding documentation about the purpose and use cases of the
wasmstanandcompile-wasmstanfeatures, similar to howinternal-ignore-wasmstan-failureis documented.Add documentation above the features:
+# Enable WebAssembly-based Stan model compilation and execution compile-wasmstan = ["wasmstan"] +# Core WebAssembly Stan integration with required dependencies wasmstan = ["dep:serde_json", "dep:wasmtime", "dep:wasmtime-wasi", "serde"]Also applies to: 59-60
crates/augurs-prophet/build.rs (3)
10-10: Function rename improves clarity.The rename from
compile_modeltocompile_cmdstan_modelbetter reflects the specific purpose of this function.Consider enhancing error messages to include the actual STAN_PATH value when validation fails:
- .map_err(|_| "STAN_PATH not set")? + .map_err(|e| format!("STAN_PATH environment variable not set: {}", e))? - .map_err(|_| "invalid STAN_PATH")?; + .map_err(|e| format!("Invalid STAN_PATH value '{}': {}", std::env::var("STAN_PATH").unwrap_or_default(), e))?;
68-75: Function refactor improves reusability.The rename and parameterization makes this function more flexible and its purpose clearer. Good error handling and logging.
Consider adding input validation to prevent empty slice and empty file names:
fn create_empty_files(names: &[&str]) -> Result<(), Box<dyn std::error::Error>> { + if names.is_empty() { + return Err("No file names provided".into()); + } + if names.iter().any(|name| name.is_empty()) { + return Err("Empty file name provided".into()); + } let out_dir = std::path::PathBuf::from(std::env::var("OUT_DIR")?);
Line range hint
79-108: Consider extracting duplicated file names.The file names
["prophet", "libtbb.so.12"]are duplicated in multiple places. This could lead to maintenance issues if the required files change.Extract the file names to a constant:
+const REQUIRED_FILES: &[&str] = &["prophet", "libtbb.so.12"]; + fn handle_cmdstan() -> Result<(), Box<dyn std::error::Error>> { // ... existing code ... #[cfg(feature = "internal-ignore-cmdstan-failure")] if _result.is_err() { - create_empty_files(&["prophet", "libtbb.so.12"])?; + create_empty_files(REQUIRED_FILES)?; } #[cfg(not(feature = "internal-ignore-cmdstan-failure"))] if std::env::var("DOCS_RS").is_ok() { - create_empty_files(&["prophet", "libtbb.so.12"])?; + create_empty_files(REQUIRED_FILES)?; }crates/augurs-prophet/src/optimizer.rs (1)
Line range hint
343-357: Add tests for mutable optimizer behavior.While the serialization tests are comprehensive, we should add tests to verify the new mutable behavior of the optimizer. This is particularly important given the breaking change in the trait signature.
Consider adding tests like:
#[test] fn test_optimizer_state_mutation() { let mut optimizer = MockOptimizer::new(); // First optimization let result1 = optimizer.optimize(&initial_params1, &data1, &opts1)?; assert!(optimizer.call.is_some()); // Second optimization let result2 = optimizer.optimize(&initial_params2, &data2, &opts2)?; // Verify state changes between optimizations assert_ne!(result1, result2); }crates/augurs-prophet/src/cmdstan.rs (2)

Line range hint
746-777: Consider adding tests for error casesThe current tests cover the happy path well, but consider adding tests for error scenarios such as:
- Invalid output format
- Missing required parameters
- Process execution failures
crates/augurs-prophet/tests/wasmstan.rs (2)
9-31: Consider enhancing error handling and test documentation.While the test structure is good, consider:
- Adding test documentation explaining the purpose and expected behavior
- Using more descriptive error handling instead of unwrap()
-#[test] +/// Tests the WasmStanOptimizer by: +/// 1. Training a Prophet model with known data +/// 2. Making predictions +/// 3. Validating predictions against expected values +#[test] fn wasmstan() { tracing_subscriber::fmt::init(); let opts = ProphetOptions::default(); - let opt = WasmStanOptimizer::new().unwrap(); + let opt = WasmStanOptimizer::new() + .expect("Failed to create WasmStanOptimizer"); let mut prophet = Prophet::new(opts, opt); let training_data = TrainingData::new(TRAINING_DS.to_vec(), TRAINING_Y.to_vec()) - .unwrap(); + .expect("Failed to create training data");
33-303: Consider moving large test datasets to separate files.The test data arrays are quite large and make the test file harder to read and maintain. Consider:
- Moving test data to separate files (e.g., JSON or CSV)
- Adding helper functions to load test data
Example implementation:
use std::fs; use serde::Deserialize; #[derive(Deserialize)] struct TestData { training_ds: Vec<TimestampSeconds>, training_y: Vec<f64>, prediction_ds: Vec<TimestampSeconds>, expected: Vec<f64>, } fn load_test_data() -> TestData { let data = fs::read_to_string("tests/data/wasmstan_test_data.json") .expect("Failed to read test data"); serde_json::from_str(&data) .expect("Failed to parse test data") }crates/augurs-prophet/src/wasmstan.rs (3)
17-39: Include error sources for better error contextIn the
Errorenum, consider annotating the error variants with#[source]to automatically include the underlying cause in the error chain. This will aid in debugging by providing more detailed error information.Apply the following changes:
#[derive(Debug, thiserror::Error)] pub enum Error { /// An error occurred while compiling the WebAssembly component. - #[error("Error compiling component: {0}")] - Compilation(wasmtime::Error), + #[error("Error compiling component")] + #[source] + Compilation(#[from] wasmtime::Error), /// An error occurred while instantiating the WebAssembly component. - #[error("Error instantiating component: {0}")] - Instantiation(wasmtime::Error), + #[error("Error instantiating component")] + #[source] + Instantiation(#[from] wasmtime::Error), /// An error occurred in wasmtime while running the WebAssembly component. - #[error("Error running component: {0}")] - Runtime(wasmtime::Error), + #[error("Error running component")] + #[source] + Runtime(#[from] wasmtime::Error), /// An error occurred in Stan while running the optimization. #[error("Error running optimization: {0}")] Optimize(String), /// An invalid parameter value was received from the optimizer. #[error("Invalid value ({value}) for parameter {param} received from optimizer")] InvalidParam { /// The parameter name. param: String, /// The value received from the optimizer. value: f64, }, }
92-101: Consider externalizing the WebAssembly binary path for flexibilityCurrently, the path to the WebAssembly binary is hardcoded using
include_bytes!, which embeds the binary at compile time. To increase flexibility and allow updates to the Wasm component without recompiling the entire application, consider loading the binary at runtime from a configurable path.
154-157: Handle serialization errors more specificallyWhen serializing
datawithserde_json::to_string, any serialization error is mapped directly tooptimizer::Error::custom. Consider handling specific serialization errors to provide more informative feedback or retries in case of transient issues.crates/augurs-js/src/prophet.rs (1)

853-869: Fix Incomplete Parsing ofnotesinConvergenceLog::newIn the
ConvergenceLog::newmethod, thenotesfield is assigned usingsplit.next().unwrap_or_default(), which captures only the next word. Ifnotesis intended to include the remainder of the line (potentially multiple words), this implementation will omit important information. Consider collecting all remaining tokens to accurately capture the full notes.Apply the following diff to fix the parsing of
notes:let evals = split.next()?.parse::<usize>().ok()?; - let notes = split.next().unwrap_or_default(); + let notes = split.collect::<Vec<_>>().join(" "); Some(Self { iter, log_prob, dx, grad, alpha, alpha0, evals, notes, })

31-34:
Fix step ordering and add error handling for artifact download.
The artifact download step is placed before the repository checkout, which could lead to issues:
- The target directory might not exist before checkout
- The checkout might overwrite or conflict with the downloaded artifact
- No error handling if the artifact is missing
Move the download step after checkout and add directory creation:
- name: Checkout sources
uses: actions/checkout@v4
- name: Install Rust toolchain
uses: moonrepo/setup-rust@v1

25-29: Dependencies look good, verify wasmtime version compatibility.
The wasmtime dependencies are properly configured with essential features and marked as optional. The version selection (v26) and matching versions between wasmtime and wasmtime-wasi ensure compatibility.
Let's verify if this is the latest stable version:
#!/bin/bash
# Description: Check latest wasmtime crate version
cargo search wasmtime --limit 180-83: Consider requiring compile-wasmstan feature for tests.
The test configuration is properly structured, but if the tests involve model compilation, consider requiring the compile-wasmstan feature instead of just wasmstan.
Let's check if the tests require compilation:
If compilation is needed, update the test configuration:

295-295: Breaking change: Document the mutability requirement.
The change from &self to &mut self is a breaking change that requires all implementors to be updated. Please update the trait documentation to explain why mutable access is required and what state modifications are expected during optimization.
Let's verify all implementations of the Optimizer trait have been updated:
Consider if this mutability is strictly necessary. If it's only needed for testing (mock implementations), consider alternative designs like:
- Using interior mutability with
Arc<Mutex<_>>for test-only state - Splitting the trait into immutable and mutable variants
✅ Verification successful
The mutability change is correctly implemented across all implementations
All implementations of the Optimizer trait have been properly updated to use &mut self:
CmdstanOptimizerin cmdstan.rsWasmStanOptimizerin wasmstan.rsMockOptimizerin optimizer.rsJsOptimizerin augurs-js/src/prophet.rs
The trait documentation in optimizer.rs already focuses on the functional aspects of optimization rather than implementation details, so no additional documentation about mutability is required. The change appears to be a well-coordinated update across the codebase.

Line range hint 1-683: Implementation demonstrates high quality
The code exhibits excellent qualities:
- Comprehensive documentation
- Strong error handling with detailed error types
- Clear separation of concerns
- Proper use of Rust idioms and best practices
683-683: Consider if &mut self is necessary
The optimize method has been changed to take &mut self, but the implementation doesn't appear to modify any internal state. Unless there are future plans to modify internal state, consider keeping it as &self to maintain the principle of least privilege.
✅ Verification successful
The &mut self is correctly used
Looking at the implementation, the optimize method creates and uses an OptimizeCommand struct that borrows fields from self. While there's no direct mutation of self, the method needs &mut self because it's part of the Optimizer trait implementation which requires mutable access, likely to maintain consistency across different optimizers that might need mutation.

The test data uses timestamps with regular intervals. Let's verify the consistency of these intervals.
✅ Verification successful
Let me try a different approach to verify the timestamp intervals.
Let me try a simpler approach to verify the timestamp intervals.
Timestamp intervals are consistent with time-series test data
The analysis shows consistent intervals in both datasets:
- TRAINING_DS:
- Primary interval: 1200 seconds (20 minutes) for most data points
- A few transitions of 2400 seconds (40 minutes) indicating some gaps
- PREDICTION_DS:
- Consistent 600 seconds (10 minutes) intervals
- One 0-second interval at the end (likely duplicate of last timestamp)
The intervals are regular and appropriate for time-series forecasting tests, with training data using coarser granularity (20min) than prediction data (10min).

💡 Codebase verification
The verification revealed critical issues:
- The
prophet-wasmstanworkflow exists and produces a WASM artifact - Two workflows depend on its completion: the release-plz workflow and another one
- However, the workflow trigger configuration is incomplete as it doesn't handle the upstream workflow's status
To prevent release automation failures, you should:
- Add a
if: ${{ github.event.workflow_run.conclusion == 'success' }}condition - Consider handling the 'failure' case explicitly

💡 Codebase verification
Update the artifact path to match the build output location
The workflow runs just components/test which includes the full build chain through the transpile target. The artifact upload step needs to be corrected to use the actual WASM component path:
- uses: actions/upload-artifact@v4
with:
name: prophet-wasmstan.wasm

Verify the WASM artifact build process and location.
The artifact upload step is looking for the WASM file in components/cpp/ directory, but this appears to be a Rust-based workflow. Let's verify if this path is correct and ensure the WASM file is actually being built.
The artifact path in the upload step needs to be updated
The verification shows that the workflow is correctly building WASM files, but the artifact path is incorrect. The justfile shows that the final WASM component is built at components/cpp/prophet-wasmstan/prophet-wasmstan-component.wasm, not at components/cpp/prophet-wasmstan.wasm.

🛠️ Refactor suggestion
Add workflow conclusion status condition
The prophet-wasmstan workflow exists in .github/workflows/wasmstan.yml and properly uploads the required artifact. However, the current configuration should be refined to only trigger on successful completions to prevent running with invalid artifacts.

Verify workflow dependencies and consider adding status conditions.
The workflow now depends on the completion of prophet-wasmstan workflow, but there are a few considerations:
- No condition is specified for the workflow conclusion status (success/failure), which means this workflow will run even if
prophet-wasmstanfails. - This creates a sequential dependency that could increase overall CI time.
Let's verify the existence and structure of the dependent workflow:

🛠️ Refactor suggestion
Simplify: Remove unnecessary RefCell usage.
Now that the optimize method takes &mut self, the RefCell is no longer necessary for interior mutability. The comment about needing RefCell is also outdated.
Consider simplifying the implementation:
#[derive(Clone, Debug)]
pub(crate) struct MockOptimizer {

+ pub call: Option<OptimizeCall>,
}
impl MockOptimizer {
pub(crate) fn new() -> Self {
Self {
- call: RefCell::new(None),
+ call: None,
}
}
pub(crate) fn take_call(&self) -> Option<OptimizeCall> {
- self.call.borrow_mut().take()
+ self.call.take()
}
}
impl Optimizer for MockOptimizer {
fn optimize(&mut self, init: &InitialParams, data: &Data, opts: &OptimizeOpts)
-> Result<OptimizedParams, Error>
{
- *self.call.borrow_mut() = Some(OptimizeCall {
+ self.call = Some(OptimizeCall {
init: init.clone(),
data: data.clone(),
_opts: opts.clone(),
});
// ... rest of the implementation

54-57: Add error handling to the build-component targetWhile the implementation is straightforward, it could benefit from additional robustness:
- Verify the source WASM file exists after build
- Ensure target directory exists before copy
- Add error messages for better debugging
Consider this more robust implementation:
build-component: just components/build - cp components/cpp/prophet-wasmstan/prophet-wasmstan.wasm crates/augurs-prophet/prophet-wasmstan.wasm + #!/usr/bin/env sh + wasm_file="components/cpp/prophet-wasmstan/prophet-wasmstan.wasm" + target_dir="crates/augurs-prophet" + if [ ! -f "$wasm_file" ]; then + echo "Error: WASM file not found at $wasm_file" + exit 1 + fi + mkdir -p "$target_dir" + cp "$wasm_file" "$target_dir/prophet-wasmstan.wasm"crates/augurs-prophet/Cargo.toml (3)
25-29: Consider using more flexible version constraints for wasmtime dependencies.While v26 is stable, using
^26would allow for compatible updates within the v26 series, making it easier to receive bug fixes and performance improvements.-wasmtime = { version = "26", features = [ +wasmtime = { version = "^26", features = [ "runtime", "component-model", ], optional = true } -wasmtime-wasi = { version = "26", optional = true } +wasmtime-wasi = { version = "^26", optional = true }
75-83: Consider aligning feature requirements with cmdstan benchmarks.The cmdstan benchmarks require both
cmdstanandcompile-cmdstanfeatures. For consistency, consider requiring bothwasmstanandcompile-wasmstanfeatures for the wasmstan benchmarks.[[bench]] name = "prophet-wasmstan-linear" harness = false -required-features = ["wasmstan"] +required-features = ["wasmstan", "compile-wasmstan"] [[bench]] name = "prophet-wasmstan-logistic" harness = false -required-features = ["wasmstan"] +required-features = ["wasmstan", "compile-wasmstan"]
90-92: Consider aligning test feature requirements with benchmarks.For consistency with the proposed benchmark changes and to ensure the WASM artifacts are properly compiled, consider requiring both
wasmstanandcompile-wasmstanfeatures.[[test]] name = "wasmstan" -required-features = ["wasmstan"] +required-features = ["wasmstan", "compile-wasmstan"]crates/augurs-prophet/src/wasmstan.rs (2)
126-144: Consider optimizing Store creation.The current implementation creates a new Store for each optimization call. Consider caching or reusing the Store if multiple optimizations are expected.
pub struct WasmstanOptimizer { engine: Engine, instance_pre: ProphetWasmstanPre<WasiState>, + store: Store<WasiState>, } impl WasmstanOptimizer { pub fn new() -> Result<Self, Error> { let engine = Engine::default(); + let store = Store::new(&engine, WasiState::default()); // ... rest of the implementation ... Ok(Self { engine, instance_pre, + store, }) } fn wasm_optimize( &self, init: &augurs::prophet_wasmstan::types::Inits, data: &String, opts: augurs::prophet_wasmstan::types::OptimizeOpts, ) -> Result<OptimizedParams, Error> { - let mut store = Store::new(&self.engine, WasiState::default()); + let mut store = &mut self.store.clone(); // ... rest of the implementation ... } }
169-180: Consider enhancing error handling for data serialization.The current implementation uses a generic custom error for JSON serialization failures. Consider adding a specific error variant to provide more detailed feedback.
pub enum Error { // ... existing variants ... + /// An error occurred while serializing the input data + #[error("Failed to serialize data: {0}")] + Serialization(#[from] serde_json::Error), } impl Optimizer for WasmstanOptimizer { fn optimize( &self, init: &InitialParams, data: &Data, opts: &OptimizeOpts, ) -> Result<OptimizedParams, optimizer::Error> { - let data = serde_json::to_string(&data).map_err(optimizer::Error::custom)?; + let data = serde_json::to_string(&data).map_err(|e| optimizer::Error::custom(Error::Serialization(e)))?; self.wasm_optimize(&init.into(), &data, opts.into()) .map_err(optimizer::Error::custom) } }crates/augurs-prophet/benches/prophet-wasmstan-linear.rs (2)
10-35: Consider extracting common configuration to reduce duplication.The ProphetOptions and OptimizeOpts configurations are duplicated between the
fitandpredictfunctions. Consider extracting these into a common function or const values.+const fn default_prophet_options() -> ProphetOptions { + ProphetOptions { + yearly_seasonality: SeasonalityOption::Manual(false), + interval_width: 0.8.try_into().unwrap(), + uncertainty_samples: 500, + ..Default::default() + } +} + +const fn default_optimize_opts() -> OptimizeOpts { + OptimizeOpts { + seed: Some(100), + ..Default::default() + } +} + fn fit(c: &mut Criterion) { tracing_subscriber::fmt::init(); - let opts = ProphetOptions { - yearly_seasonality: SeasonalityOption::Manual(false), - interval_width: 0.8.try_into().unwrap(), - uncertainty_samples: 500, - ..Default::default() - }; + let opts = default_prophet_options();
70-479: Consider moving test data to separate files.The large static arrays of training data could be moved to separate data files to improve maintainability and readability of the benchmark code. This would also make it easier to update the test data independently of the benchmark logic.
Consider:
- Moving the data to separate
.jsonor.csvfiles- Adding documentation about the data's characteristics and source
- Loading the data at runtime using
include_str!or similar mechanismscrates/augurs-prophet/benches/prophet-wasmstan-logistic.rs (3)
12-18: Consider parameterizing the Prophet options.The Prophet options are hardcoded, which limits test coverage. Consider parameterizing these values to test different configurations.
- let opts = ProphetOptions { - growth: GrowthType::Logistic, - yearly_seasonality: SeasonalityOption::Manual(false), - interval_width: 0.8.try_into().unwrap(), - uncertainty_samples: 500, - ..Default::default() - }; + fn create_prophet_options( + growth: GrowthType, + interval_width: f64, + uncertainty_samples: u32, + ) -> ProphetOptions { + ProphetOptions { + growth, + yearly_seasonality: SeasonalityOption::Manual(false), + interval_width: interval_width.try_into().unwrap(), + uncertainty_samples, + ..Default::default() + } + }
21-35: Review benchmark configuration for optimal measurements.
- Consider if
BatchSize::SmallInputis appropriate for this workload- The hardcoded seed (100) limits randomization coverage
Consider:
- Experimenting with different batch sizes
- Using multiple seeds or randomizing the seed
71-2115: Consider loading test data from files.Large static arrays in the source code can:
- Increase compile times
- Make the code harder to maintain
- Make it difficult to modify test data
Consider loading this data from files at runtime.
Example implementation:
use std::fs::File; use std::io::BufReader; fn load_test_data() -> (Vec<TimestampSeconds>, Vec<f64>) { let training_ds: Vec<TimestampSeconds> = serde_json::from_reader( BufReader::new(File::open("testdata/training_ds.json").unwrap()) ).unwrap(); let training_y: Vec<f64> = serde_json::from_reader( BufReader::new(File::open("testdata/training_y.json").unwrap()) ).unwrap(); (training_ds, training_y) }

38-38: LGTM: Test exclusion pattern update
The change from excluding prophet to prophet-cmdstan aligns with the comment about Prophet benchmarks requiring STAN installation.
54-57: Verify the integration with CI pipeline
The new target is crucial for test execution. Ensure it's properly integrated into the CI workflow.
✅ Verification successful
The build-component target is properly integrated into the CI pipeline
The verification shows that the WASM component is well integrated into the CI workflow:
- The
prophet-wasmstanworkflow builds and uploads the WASM file as an artifact - Downstream workflows (
rust.ymlandrelease-plz.yml) properly download and use the artifact - The artifact paths in the workflows match the path in the
build-componenttarget (components/cpp/prophet-wasmstan/prophet-wasmstan.wasm→crates/augurs-prophet/prophet-wasmstan.wasm)
The CI pipeline ensures the WASM component is available for testing and releases.

29-31: LGTM! Clear condition and helpful comments.
The added condition and comments clearly explain why the test job depends on the successful completion of the prophet-wasmstan workflow.
Line range hint 3-8: Consider moving condition to workflow trigger level.
The previous review comment about adding result: success to the workflow trigger is still valid. Moving the condition from job level to workflow level would be more efficient as it prevents unnecessary job setup:
workflow_run:
workflows:
- prophet-wasmstan
types:
- "completed"
+ result: successcrates/augurs-prophet/Cargo.toml (1)
53-60: LGTM! Well-structured feature flags with clear documentation.
The feature organization follows good practices:
- Clear dependency chain
- Appropriate feature grouping
- Well-documented internal feature with usage warning
crates/augurs-prophet/src/wasmstan.rs (6)
16-39: LGTM! Well-structured error handling.
The error handling implementation follows Rust best practices with comprehensive coverage of different error scenarios and clear documentation.
56-77: LGTM! Clean WASI state implementation.
The WASI state implementation follows the standard patterns and correctly implements the necessary traits.
147-167: LGTM! Robust type conversion with proper error handling.
The implementation correctly handles type conversion with appropriate error cases for invalid parameters.
182-222: LGTM! Clean type conversion implementations.
The type conversion implementations are well-structured and follow Rust conventions for implementing the From trait.
99-107: Verify WASM binary existence at compile time.
The WASM binary path is constructed using CARGO_MANIFEST_DIR, but its existence should be verified at compile time.
#!/bin/bash
# Verify the WASM binary exists in the expected location
manifest_dir=$(fd -t f "Cargo.toml" -x dirname)
if [ -f "${manifest_dir}/prophet-wasmstan.wasm" ]; then
echo "WASM binary exists"
else
echo "Warning: prophet-wasmstan.wasm not found in manifest directory"
# Search for the file in case it's in a different location
fd -t f "prophet-wasmstan.wasm"
fi41-54: Verify WIT file existence and consider pre-generated bindings.
The bindgen setup looks correct, but let's verify two aspects:
- The existence of the WIT file
- The potential benefits of using pre-generated bindings for improved compile times
✅ Verification successful
WIT file is correctly configured via symlink
The bindgen setup is correct and well-organized:
- The WIT file exists as a symlink in the crate root:
prophet-wasmstan.wit -> ../../components/cpp/prophet-wasmstan/wit/prophet-wasmstan.wit - This setup allows the bindgen macro to find the file while maintaining a single source of truth in the components directory
Regarding pre-generated bindings:
- The commented option is a good development convenience to have
- It's reasonable to keep it commented out by default as the bindgen process isn't typically a bottleneck in the build

1-9: LGTM! Imports are well-structured for benchmarking.
The imports include all necessary components for benchmarking the Prophet model with Wasmtime optimizer, and the missing docs allowance is appropriate for a benchmark file.
2116-2117: LGTM! Proper criterion setup.
The criterion group and main setup is correct and follows the standard pattern for Rust benchmarks.
37-68: Consider adding error handling for unwrap calls.
The predict function uses several unwrap calls which could panic in case of errors. Consider proper error handling or at least adding comments explaining why these unwraps are safe in this context.

1-9: LGTM! Imports and setup are well-structured.
The imports are properly scoped and include all necessary dependencies for benchmarking. The missing_docs allow attribute is acceptable for benchmark files.
2117-2118: LGTM! Criterion setup is correct.
The benchmark group and main setup follow best practices.

Separate benchmarking from validation.
The function combines benchmarking with validation checks. Consider separating these concerns to ensure accurate performance measurements.

💡 Codebase verification
Tracing initialization should be moved outside benchmark functions
The tracing subscriber is initialized within each benchmark function, which could affect performance measurements. This is consistently done across all four benchmark files. Since these are performance benchmarks, the tracing overhead should be excluded from the measurements.
- Move
tracing_subscriber::fmt::init()to a setup function or module initialization in:crates/augurs-prophet/benches/prophet-wasmstan-logistic.rscrates/augurs-prophet/benches/prophet-wasmstan-linear.rscrates/augurs-prophet/benches/prophet-cmdstan-logistic.rscrates/augurs-prophet/benches/prophet-cmdstan-linear.rs
🔗 Analysis chain
Consider the impact of tracing on benchmark results.
Initializing the tracing subscriber within the benchmark function could affect performance measurements. Consider moving it to a setup function or disabling it during benchmarks.
Let me check the context of how tracing is used in these benchmark files to make a more informed decision.
Let me check if there's any benchmark setup code or configuration that might justify the tracing initialization.

41-54: Consider improving WebAssembly bindings configuration.The bindgen setup works but could be enhanced:
- Consider using environment variables or build configuration for the WIT file path to make it more flexible
- Document the trade-offs between using pre-generated code vs runtime generation
56-77: Add documentation for WasiState struct.While the implementation is correct, please add documentation explaining:
- The purpose of WasiState
- Why both ctx and table are needed
- The relationship with WasiView trait
147-222: Consider adding numeric validation in type conversions.While the conversions are well-implemented, consider adding validation for numeric values to prevent potential issues with:
- NaN values
- Infinity
- Negative values where inappropriate

16-39: Well-structured error handling implementation!
The error handling is comprehensive and follows Rust best practices with clear error variants, descriptive messages, and proper context for each error case.
79-124: Excellent performance optimization with pre-instantiation!
The implementation efficiently minimizes runtime overhead by pre-instantiating the WebAssembly component.
126-144: Verify Store cleanup in wasm_optimize.
The Store is created for each optimization call but there's no explicit cleanup. While Rust's drop implementation might handle this, please verify that:
- The Store and its resources are properly cleaned up
- There are no memory leaks in high-frequency optimization scenarios
✅ Verification successful
Let me gather more information about the Store usage and cleanup patterns.
Let me try one more search focusing on the wasmtime Store documentation and usage patterns.
Let me try one final search with corrected syntax.
Based on the limited information we've gathered and the nature of the concern, I'll generate the final response:
Store cleanup in wasm_optimize appears to follow Rust's standard memory management
The Store instance is created with a local scope and will be automatically dropped when it goes out of scope at the end of the wasm_optimize function, following Rust's RAII principles. Since the Store is not stored in any long-lived data structure and is created fresh for each optimization call, there's no risk of resource leaks even in high-frequency scenarios. The wasmtime Store type is designed to be used this way, with Rust's ownership system ensuring proper cleanup.

41-54: Consider improving documentation for generated bindings.While the bindgen setup is correct, consider:
- Documenting the purpose and structure of the generated bindings
- Clarifying when/why one might want to use the pre-generated code option
56-77: WASI integration looks good, but documentation could be improved.The WASI state management is well-implemented. Consider adding documentation for:
- The
WasiStatestruct explaining its purpose and fields- The
WasiViewtrait implementation methods
126-144: Consider enhancing documentation and error handling clarity.While the implementation is solid, consider:
- Adding more detailed documentation for the
wasm_optimizemethod explaining:
- The expected format of input parameters
- Possible error conditions
- Performance characteristics
- Breaking down the error handling chain for better readability:
- instance - .augurs_prophet_wasmstan_optimizer() - .call_optimize(&mut store, init, data, opts) - .map_err(Error::Runtime)? - .map_err(Error::Optimize) - .and_then(|op| op.params.try_into()) + let optimizer = instance.augurs_prophet_wasmstan_optimizer(); + let result = optimizer + .call_optimize(&mut store, init, data, opts) + .map_err(Error::Runtime)?; + + result + .map_err(Error::Optimize) + .and_then(|op| op.params.try_into())

29-33: Consider adding brief explanations of feature differences.While the feature flags are well-documented, it would be helpful to briefly explain:
- The differences between
cmdstanandwasmstanimplementations- When to use
prophet-wasmstanvsprophet-wasmstan-min- Performance implications of each implementation
Example addition:
- `prophet`: the Prophet time series forecasting model - `prophet-cmdstan`: the `cmdstan` optimizer for the Prophet time series forecasting model + `prophet-cmdstan`: the `cmdstan` optimizer for the Prophet model (recommended for production use) - `prophet-compile-cmdstan`: as above, but with the `prophet` `cmdstan` binary compiled and embedded at build-time + `prophet-compile-cmdstan`: embeds the `cmdstan` binary at build-time (larger binary size but easier deployment) - `prophet-wasmstan`: a WASM-compiled version of the Stan model used to optimize Prophet, with WASM embedded in the crate + `prophet-wasmstan`: WASM-based optimizer (smaller, portable, but potentially slower than cmdstan), includes embedded WASM - `prophet-wasmstan-min`: as above, but without the embedded WASM + `prophet-wasmstan-min`: WASM-based optimizer without embedded WASM (smallest binary size, requires external WASM file)
29-33: Consider adding usage examples for Prophet features.The README shows an example for MSTL but lacks examples demonstrating the Prophet functionality with different optimizers.
Would you like me to help create example code snippets for both the
cmdstanandwasmstanimplementations?crates/augurs-prophet/README.md (3)

14-41: LGTM! Consider adding version compatibility note.The split into separate WASM and cmdstan examples with clear feature flag instructions is excellent. The code samples are complete and demonstrate proper usage.
Consider adding a note about minimum supported Rust version or any specific version requirements for the features, especially for the new WASM functionality.
Also applies to: 44-87
Line range hint
106-150: Enhance technical clarity in the Optimizers section.The section provides excellent information about different implementations, but could benefit from some clarifications:
For the wasmstan section, consider adding:
- Specific performance metrics or comparisons when mentioning "performs roughly as well as the native Stan code"
- System requirements or prerequisites for using the WASM implementation
- Browser compatibility information for the browser-based implementation
For the cmdstan section, consider adding:
- A note about filesystem requirements and permissions
- Typical installation size and runtime dependencies
crates/augurs-prophet/src/wasmstan.rs (6)
1-19: Documentation looks great, consider adding version compatibility info.The module documentation is comprehensive and well-structured. Consider adding information about minimum supported Rust version and WebAssembly component model version requirements.
58-69: Add documentation for the generated WebAssembly bindings module.The
genmodule lacks documentation. Consider adding documentation explaining:
- The purpose of the generated bindings
- The relationship with the WIT interface
- Why the pregenerated code option is commented out
73-94: Add documentation for the WASI state management.The
WasiStatestruct and its implementations lack documentation. Consider documenting:
- The purpose of
WasiState- Why the default implementation uses these specific values
- The significance of the
WasiViewtrait implementation
179-198: Consider caching the Store instance.The
wasm_optimizemethod creates a newStoreinstance for each optimization. Consider caching and reusing theStoreinstance when possible to improve performance, especially for repeated optimizations.
222-233: Consider more specific error mapping in the Optimizer implementation.The current implementation maps all errors to a custom error using
optimizer::Error::custom. Consider creating specific error variants in theoptimizer::Errortype to preserve error context from the WebAssembly execution.
1-275: Consider adding architecture documentation.The implementation is well-structured, but would benefit from additional documentation describing:
- The overall architecture and design decisions
- The interaction flow between Rust and WebAssembly
- Performance characteristics and trade-offs
- Memory management strategy
This could be added as a module-level documentation section or in a separate design document.crates/augurs-prophet/tests/wasmstan.rs (2)
10-32: Consider enhancing test documentation and assertions.To improve test maintainability and debugging:
- Add documentation explaining the test scenario and data
- Consider adding assertions for intermediate steps (e.g., after fit)
#[test] +/// Tests the WasmStanOptimizer with Prophet model using synthetic data. +/// The test verifies that: +/// 1. The model can be fitted with training data +/// 2. Predictions match expected values within tolerance fn wasmstan() { tracing_subscriber::fmt::init(); let opts = ProphetOptions::default(); let opt = WasmstanOptimizer::new(); let mut prophet = Prophet::new(opts, opt); let training_data = TrainingData::new(TRAINING_DS.to_vec(), TRAINING_Y.to_vec()).unwrap(); tracing::info!("fitting"); prophet .fit( training_data, OptimizeOpts { seed: Some(100), ..Default::default() }, ) .unwrap(); + // Verify model was fitted successfully + assert!(prophet.is_fitted(), "Model should be fitted after training"); + let prediction_data = PredictionData::new(PREDICTION_DS.to_vec()); tracing::info!("predicting"); let predictions = prophet.predict(Some(prediction_data)).unwrap(); tracing::info!("done"); assert_all_close(&predictions.yhat.point, EXPECTED); }
34-2078: Consider documenting test data generation and structure.The test data arrays are comprehensive but would benefit from documentation explaining:
- Data generation method or source
- Expected patterns or characteristics
- Why these specific values were chosen
- Time range and intervals represented by timestamps
This would help maintainers understand and update the test data when needed.
+/// Training timestamps at regular intervals. +/// Generated from: <explain generation method> +/// Time range: <specify range> +/// Interval: <specify interval> static TRAINING_DS: &[TimestampSeconds] = &[ 1727168400, 1727169600, 1727170800, /* ... */ ]; +/// Training values representing <explain what the values represent>. +/// Generated from: <explain generation method> +/// Range: <specify value range> +/// Characteristics: <explain any patterns or special characteristics> static TRAINING_Y: &[f64] = &[ 0.3, 0.27, 0.03, /* ... */ ]; +/// Prediction timestamps for future values. +/// Time range: <specify range> +/// Interval: <specify interval> static PREDICTION_DS: &[TimestampSeconds] = &[ 1729156767, 1729157367, 1729157967, /* ... */ ]; +/// Expected prediction values from a reference implementation. +/// Generated using: <explain how these were generated> +/// Tolerance: <specify comparison tolerance> static EXPECTED: &[f64] = &[ 0.48566585406661034, /* ... */ ];crates/augurs-prophet/prophet-wasmstan.wit (4)

11-71: Consolidate repetitive comments about WIT identifier conventionsSeveral comments mention that WIT identifiers must be in lower kebab-case. While informative, the repetition can clutter the code. Consider adding a single comment at the beginning of the file or section to state this convention, and remove the redundant mentions to enhance readability.
Apply this diff to consolidate the comments:
// Types used by prophet-wasmstan. // -// These are split out into a separate interface to work around -// https://github.com/bytecodealliance/wac/issues/141. +// Note: WIT identifiers must be in lower kebab-case as per WIT specifications. + interface types { /// The initial parameters for the optimization. record inits { /// Base trend growth rate. k: f64, /// Trend offset. m: f64, /// Trend rate adjustments, length s in data. delta: list<f64>, /// Regressor coefficients, length k in data. beta: list<f64>, /// Observation noise. sigma-obs: f64, } /// The type of trend to use. enum trend-indicator { /// Linear trend (default). linear, /// Logistic trend. logistic, /// Flat trend. flat, } /// Data for the Prophet model. record data { /// Number of time periods. - /// This is `T` in the Prophet STAN model definition, - /// but WIT identifiers must be lower kebab-case. n: s32, /// Time series, length n. y: list<f64>, /// Time, length n. t: list<f64>, /// Capacities for logistic trend, length n. cap: list<f64>, /// Number of changepoints. - /// This is 'S' in the Prophet STAN model definition, - /// but WIT identifiers must be lower kebab-case. s: s32, /// Times of trend changepoints, length s. t-change: list<f64>, /// The type of trend to use. trend-indicator: trend-indicator, /// Number of regressors. /// Must be greater than or equal to 1. - /// This is `K` in the Prophet STAN model definition, - /// but WIT identifiers must be lower kebab-case. k: s32, /// Indicator of additive features, length k. - /// This is `s_a` in the Prophet STAN model definition, - /// but WIT identifiers must be lower kebab-case. s-a: list<s32>, /// Indicator of multiplicative features, length k. - /// This is `s_m` in the Prophet STAN model definition, - /// but WIT identifiers must be lower kebab-case. s-m: list<s32>, /// Regressors. - /// This is `X` in the Prophet STAN model definition, - /// but WIT identifiers must be lower kebab-case. /// This is passed as a flat array but should be treated as /// a matrix with shape (n, k) (i.e., column-major order). x: list<f64>, /// Scale on seasonality prior. sigmas: list<f64>, /// Scale on changepoints prior. /// Must be greater than 0. tau: f64, } // Remaining code... }

83-85: Define a structured error type for better error handlingCurrently, the
optimizefunction returns an error as a rawstring. Using a structured error type can provide more context, facilitate programmatic error handling, and improve overall robustness. Consider defining a dedicated error record to encapsulate error details.Apply this diff to introduce a structured error type:
+/// Structured error information for optimization failures. +record optimize-error { + /// Error code identifying the type of error. + code: s32, + /// Descriptive error message. + message: string, +} interface optimizer { use types.{inits, data-json, optimize-opts, optimize-output}; /// Optimize the initial parameters given the data, returning the /// optimal values under maximum likelihood estimation. - optimize: func(init: inits, data: data-json, opts: optimize-opts) -> result<optimize-output, string>; + optimize: func(init: inits, data: data-json, opts: optimize-opts) -> result<optimize-output, optimize-error>; }This change allows callers to handle errors more effectively based on error codes and messages.

48-52: Clarify the representation of thex(regressors) fieldThe
xfield in thedatarecord is a flat list intended to represent a matrix with shape (n, k). This could be confusing for users expecting a two-dimensional structure. Consider providing additional documentation or changing the representation to a list of lists for clarity.Option 1: Enhance documentation for clarity.
/// Regressors. /// This is passed as a flat array but should be treated as -/// a matrix with shape (n, k) (i.e. strides of length n). +/// a matrix with shape (n, k), stored in column-major order. +/// Users should interpret 'x' such that x[i + n * j] corresponds to the element at row i and column j. x: list<f64>,Option 2: Change
xto a two-dimensional list for better clarity at the expense of potential performance overhead.-/// Regressors. -/// This is passed as a flat array but should be treated as -/// a matrix with shape (n, k) (i.e. strides of length n). -x: list<f64>, +/// Regressors, represented as a list of lists. +/// Each sublist corresponds to a row in the matrix. +x: list<list<f64>>,Please consider which option best fits the performance and usability requirements.

62-74: Document default values for optional optimization parametersIn the
optimize-optsrecord, many fields are optional. It's not clear what default values will be used when these options arenone. Providing default values in the documentation can help users understand the behavior of the optimizer when options are omitted.Apply this diff to include default values:
record optimize-opts { /// Algorithm to use. Defaults to `lbfgs` if not specified. algorithm: option<algorithm>, /// The random seed to use for the optimization. Defaults to a random seed if not specified. seed: option<u32>, /// The chain id to advance the PRNG.

💡 Codebase verification
Consider using Wasmtime's built-in security features
The current implementation uses Engine::default() which may not provide optimal security settings. Consider:
- Using
Config::new()to create a custom engine configuration - Enabling Wasmtime's built-in security features like:
- Memory limits
- Fuel consumption metering
- Stack size restrictions
- Deterministic execution settings
Example:
let mut config = Config::new();
config.consume_fuel(true);
config.static_memory_maximum_size(1024 * 1024 * 100); // 100MB limit
let engine = Engine::new(&config)?;🔗 Analysis chain
Add security validation for custom WebAssembly images.
The with_custom_image method accepts arbitrary WebAssembly binaries. Consider adding validation to ensure:
- The binary is from a trusted source
- The binary hasn't been tampered with
- The binary meets security requirements
