Release v2.8.0 · ralforion/orionbelt-semantic-layer

[2.8.0] - 2026-06-02

Session-scoped OSI model endpoints. Two new endpoints bridge the model store with Open Semantic Interchange (OSI), distinct from the existing stateless /v1/convert/* transforms:
- POST /v1/sessions/{id}/models/from-osi accepts OSI YAML (osi_yaml), converts it to OBML, and loads the result into the session's model store. Returns the standard model summary plus conversion_warnings and the advisory OSI input_validation.
- GET /v1/sessions/{id}/models/{mid}/osi exports a loaded model from the store as OSI YAML, with optional ?model_name=, ?model_description=, and ?ai_instructions= overrides.
ModelStore.get_raw(): public accessor for a model's raw OBML dict, preferring the faithful copy captured at load time and returning a deep copy so callers cannot mutate internal state.

OSI converter not packaged for non-editable wheel installs. The converter (repo-root osi-obml/) was only discoverable via repo-root or /app paths, so a PyPI wheel or Docker install raised ModuleNotFoundError from the /convert and new OSI endpoints. The converter module and its OSI schema are now bundled into the wheel as package data under orionbelt/_osi_obml/ (hatch force-include), and the lookup searches that location first. Verified on a clean wheel install.
Mermaid ER diagram clipped every label by one character (string to strin, Supplier to Supplie). Mermaid pre-measures ER column and edge-label widths with the theme fontFamily, but the browser painted text with a wider font the host CSS cascaded in. Pinned a local-only font stack (Helvetica, Arial, sans-serif) in the diagram's %%{init}%% themeVariables.fontFamily and forced the same family on the rendered ER text, so measure-time and paint-time use the identical font.
