Summary

Replace TinyMemory's direct TinyAgents dependency with provider-neutral TinyInference, remove the redundant top-level TinyAgents submodule, and update the embedded TinyCortex gitlink to the merged tinyhumansai/tinycortex#159. TinyInference is pinned to current main (cc8aca4), and all first-party crates are relicensed under GPL-3.0-only.

Related issue

None. Dependency tinyhumansai/tinycortex#159 is merged.

API or behavior changes

  • Breaking: chat and embedding integrations now use TinyInference model/message/embedding types instead of TinyAgents paths.
  • Breaking: project license changes from MIT metadata to GPL-3.0-only.
  • Ollama retains its 8K context and batch request policy through the canonical TinyInference implementation.
  • TinyAgents is absent from the Cargo dependency graph.

Validation

Commands actually run, with their outcome:

  • cargo fmt --all -- --check
  • cargo clippy --all-targets --all-features -- -D warnings
  • cargo build --all-targets --all-features
  • cargo test --all-features
  • cargo fmt --manifest-path crates/tinymemory-module/Cargo.toml -- --check
  • cargo clippy --manifest-path crates/tinymemory-module/Cargo.toml --all-targets --all-features -- -D warnings
  • cargo build --manifest-path crates/tinymemory-module/Cargo.toml --all-targets --all-features
  • cargo test --manifest-path crates/tinymemory-module/Cargo.toml --all-features

Tests

Updated the TinyBus chat bridge tests to pin TinyInference response metadata and cache identity. The full workspace suite, 68 module unit tests, and all isolated dynamic-module loader cases pass.

Documentation

Updated the dependency/consumer patch instructions, tree ownership notes, module dependency explanation, and GPL license metadata.

Checklist

  • The change is focused on replacing the inference boundary and its licensing/dependency consequences
  • No new #[allow(...)], #[ignore], or relaxed lints
  • No secrets, tokens, or .env contents in the diff or the description

Summary by CodeRabbit

  • New Features

    • Migrated chat and embedding integrations to the TinyInference provider-neutral interface.
    • Added consistent normalization for profile-store tokens and connection identifiers.
    • Improved identifier truncation to safely support Unicode text.
  • Bug Fixes

    • Prevented errors when truncating identifiers containing multi-byte characters.
  • Documentation

    • Updated setup, architecture, and integration guidance to reflect TinyInference.
    • Clarified that historical build measurements require re-evaluation.
  • License

    • Updated project components to GPL-3.0-only licensing.

Add the tinylinference repository as a submodule under vendor/tinylinference to make the dependency available for local development and builds.

Replace the TinyAgents SDK dependency with the provider-neutral TinyInference crate across the workspace. TinyMemory's core and module crates only need the chat and embedding model traits, not the agent runtime or session behavior that TinyAgents bundles. The new dependency is lighter and avoids carrying a second top-level submodule checkout, since TinyCortex already pins TinyAgents internally.

Replace the tinyagents dependency with the new tinyinference crate across the embedding adapter, factory, and test files. This change consolidates embedding functionality into a dedicated inference crate, removing the unused rusqlite dependency and cleaning up formatting in error messages and assertions.

Co-authored-by: Medulla <medulla@tinyhumans.ai>
The Cargo.lock file is updated to reflect the addition of the `httpdate` crate and the new `tinyinference` workspace crate, along with the removal of the `rusqlite` and `tinyagents` dependencies from the `tinymemory-module` crate. This keeps the lock file in sync with the current dependency graph after changes to the workspace's Cargo.toml files.

Co-authored-by: Medulla <medulla@tinyhumans.ai>
The `cache_identity` method was removed from `BusChatModel` and its corresponding test assertion was deleted because the caching identity concept is no longer needed for the bus-based chat model.

The branch setting was removed from the tinyagents submodule configuration so that the submodule will track the commit referenced in the parent repository rather than following a moving branch target.

Auto-committed-on: macbook
Co-authored-by: Medulla <medulla@tinyhumans.ai>
Remove the top-level tinyagents submodule and update all references to point to tinyinference instead, since the engine now uses TinyCortex's internal TinyAgents pin rather than a workspace-level one. The README and inline documentation are updated to reflect that tinyinference is the provider-neutral inference API consumed by the memory layer, while TinyAgents remains a transitive dependency of TinyCortex only.

The TinyInference embedding adapter and its associated test module have been removed from the core crate. This code is no longer needed as the embedding provider abstraction has been relocated to a different part of the codebase.

…ache identity

Replace the custom `LongContextOllamaEmbeddingModel` with the upstream `OllamaEmbeddingModel` from tinyinference, which now handles context token configuration internally. This change also adds a `cache_identity` method to the bus chat model to enable response caching per role, and updates test fixtures to include new required fields for chat responses.

Add an assertion to confirm that the model created via the chat bridge returns the expected cache identity, ensuring the identity propagation works correctly across module boundaries.

The `short_id` and `title_case` utility functions were only used in test code, so they have been moved into the test module to keep the production code lean and avoid dead code warnings. An orphaned doc comment in the identity module was also removed as part of this cleanup.

Moved the `tinyinference` import after the `crate` imports to follow the standard Rust import ordering convention where external crate imports come after local crate imports.

The `TestComposioHost` struct and its associated `NO_SESSION` constant were removed from the test seams module because they are no longer referenced by any test or production code, reducing dead code and simplifying the test infrastructure.
