Summary

  • add a loadable TinyBus module for compression, CCR retrieval, and cache configuration
  • keep the optional ML runtime behind a host callback over the module bus
  • publish platform-native module bundles and checksums from the release workflow
  • retain the independently publishable TinyJuice crate

API Or Behavior Changes

Adds the ai.tinyhumans.tinyjuice.Compression module interface. Existing Rust APIs remain compatible; four wire-facing types now derive serde traits.

Tests

  • cargo fmt --all -- --check
  • cargo clippy --all-targets --all-features -- -D warnings
  • cargo build --release -p tinyjuice-module
  • real module loader E2E via TINYJUICE_TEST_MODULE=... cargo test -p tinyjuice-module --test module_e2e -- --ignored
  • cargo test --all-features (460 passed, 1 expected ignored loader test)
  • cargo package --locked --package tinyjuice --allow-dirty

Documentation

Added docs/specs/tinybus-module.md and module crate documentation.

Summary by CodeRabbit

  • New Features

    • Added a native TinyJuice module for compression, content detection, cache retrieval, compaction, and statistics.
    • Added support for serializing and deserializing compression-related data.
    • Added automated builds and downloadable native packages for Linux, macOS, and Windows.
    • Added checksums, release metadata, and packaged source files to published releases.
  • Documentation

    • Documented the native module, its services, and available operations.
  • Bug Fixes

    • Improved release validation and post-publication module verification.

Review Change Stack

Warning

Review limit reached

@senamakel, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 101 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change adds a TinyBus adapter crate with compression and cache operations. It updates shared serialization, workspace configuration, module documentation, and release automation for source packages and 11 native platform bundles.

Changes

TinyBus module and release

Layer / File(s) Summary
Module workspace and data contracts
.gitmodules, vendor/tinybus, Cargo.toml, crates/tinyjuice-module/Cargo.toml, crates/tinyjuice-module/src/lib.rs, src/types.rs
The workspace includes the TinyBus submodule and a new rlib/cdylib module crate. Release profile settings and Serde derives support module packaging and wire formats.
Compression service and validation
crates/tinyjuice-module/src/service.rs, crates/tinyjuice-module/tests/module_e2e.rs, docs/specs/tinybus-module.md
The module exposes installation, detection, compression, compaction, cache retrieval, and cache statistics operations. Integration tests and the module specification cover the service behavior.
Source publishing and versioning
.github/workflows/release.yml
The publish job validates all features, resolves TinyJuice and TinyBus metadata, updates both manifests, packages both source archives, and publishes TinyJuice.
Native bundles and GitHub release
.github/workflows/release.yml
The workflow builds 11 platform bundles, uploads checksums and metadata, creates the GitHub release, and verifies an Ubuntu module through TinyBus.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🔴 Critical · up to 17cd3

The PR adds a native module and multi-platform release flow, but the current dependency checkout is missing the TinyBus manifest required for Cargo, making the module path unbuildable; the workflow also publishes the crate and tag before native bundles complete. Merge should be blocked until the dependency is restored and release ordering is corrected, with caller authorization and shared-state isolation explicitly confirmed.

Poem

I’m a rabbit with a bundled crate,
TinyBus hops through every gate.
Checksums sparkle, targets run,
Compression tucks logs in one.
Release night ends with a happy thump!

The tinybus_version output is not consumed.

The publish job exports tinybus_version, and the version step resolves and validates it. No downstream job or step reads needs.publish.outputs.tinybus_version. The TinyBus source archive uses the short revision instead. Either consume the value (for example in the release notes or the checksum manifest) or drop the resolution, the validation, and the output.

159-171: 🩺 Stability & Availability | 🔵 Trivial | 🏗️ Heavy lift

The crate is published before the native bundles are built.

The publish job pushes the tag and runs cargo publish at Line 168. The native-bundles job then builds 11 platform bundles, and github-release creates the release. A failure in any bundle job, or in the checksum step, leaves an immutable crates.io version and a pushed tag with no GitHub release and no module archives. Recovery then requires a new version bump.

Consider moving cargo publish into a final job that depends on native-bundles, and keeping cargo package in the publish job for early validation.

514-515: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Consider #[serde(default)] on CompressOptions for wire compatibility.

Every field is mandatory on the wire as written. A host must send all 15 fields, as crates/tinyjuice-module/tests/module_e2e.rs does. When a future release adds one field, all existing Install payloads break. If CompressOptions has a Default impl, #[serde(default)] keeps old payloads valid and lets hosts send only the knobs they change.

Consider documenting the wire payload shapes.

The method list is correct and matches the module_export! declaration. The serde derives make CompressOptions, ContentHint, and CompressedOutput a public JSON contract with camelCase field names. Add the request and response shapes for Install, Compress, and Retrieve, and state which fields are optional. This gives hosts the information they need and reduces payload mismatches.

As per coding guidelines: "Keep public API changes documented in README.md or docs/."

Align WireRangeUnit casing with the other wire types.

InstallRequest, CompactResponse, RetrieveRange, and CacheStats use camelCase. WireRangeUnit uses snake_case. For single-word variants the emitted values are identical today, so this is cosmetic, but the mixed attribute invites a wire mismatch when a multi-word variant is added. docs/specs/tinybus-module.md also does not state the range payload shape.

- Around line 236-284: Update the Windows package assembly in the Windows
packaging step to copy docs/specs/tinybus-module.md alongside LICENSE and
README.md into packageRoot, matching the documented contents of the Unix
package.
- Around line 150-171: Update the github-release workflow around the artifact
download and release creation steps to download the source-packages artifact
separately, then pass the .crate and tinybus-source-*.tar.gz files explicitly to
gh release create. Keep the existing module-archive download and ensure the
release’s 11-archive count remains limited to tinyjuice-module-* files.

In `@vendor/tinybus`:
- Line 1: Restore the vendor/tinybus submodule to a reachable commit containing
Cargo.toml, and update every CI Cargo build job to fetch submodules recursively
before invoking Cargo.
