v2.7.6

[2.7.6] - 2026-06-18

Bug Fixes & Technical Improvements

• Anthropic Reranker: Fixed model override being ignored — AnthropicRerankingService now unconditionally applies the reranker-specific model instead of deferring to the base class default (claude-sonnet-4-20250514); corrected model ID in config/rerankers.yaml from claude-haiku-4-5 to claude-haiku-4-5-20251001.

Core System Updates

• Install Wizard: Added an interactive setup wizard via ./install/setup.sh --wizard to configure common use cases, AI providers, API keys, and related config files non-destructively.
• Document Generation: Split the monolithic document renderer into per-format modules for PDF, DOCX, XLSX, PPTX, Markdown, and CSV, with a thin dispatcher preserving existing import paths.
• Rewrite Model Overrides: Added rewrite_model support for document generation adapters so spec-generation models can be overridden independently from the selected provider.
• Provider Caching: Fixed stale OpenAI-compatible provider client reuse by rebuilding lost SDK clients, resetting verification state, and avoiding cache retention for failed initializations.

Audio & STT

• Whisper Service: Moved synchronous transcription work into a thread pool, preserved MIME-derived file extensions for FFmpeg, and hardened cleanup behavior.
• Cohere STT: Fixed multipart field ordering so Cohere receives model and language before the uploaded file.

Chat-app & UI Improvements

• orbitchat v3.9.9: Published the latest chat client package and enabled Markdown and CSV document adapters by default.
• Document Previews: Added Markdown and CSV preview/download support, including Markdown modal rendering and capped CSV table previews.

Documentation & Configuration

• Provider Matrix: Added README matrices for inference providers, capabilities, data sources, vector databases, and integration types.
• Adapter Configs: Registered Markdown and CSV generator adapters and added rewrite_model comments across document generator adapter configs.
