## Summary by CodeRabbit
* **New Features**
* Transcriptions now produce structured meeting summaries (strict JSON)
and a normalized, speaker‑tagged, non‑overlapping transcript with legacy
projection support.
* **API**
* Submission accepts richer transcription input; results return
source‑audio metadata, slice manifest, quality indicators, normalized
segments/transcript, and structured summary JSON.
* **Frontend**
* Recording flow stores transcription metadata and uploads preprocessed
audio slices with slice/quality info; UI-side result normalization
applied.
* **Tests**
* Expanded unit, contract, and e2e coverage for normalization, payload
parsing, persistence/retry, and end‑to‑end transcription flows.

## Summary by CodeRabbit
* **New Features**
* Native LLM workflows: structured outputs, embeddings, and reranking
plus richer multimodal attachments (images, audio, files) and improved
remote-attachment inlining.
* **Refactor**
* Tooling API unified behind a local tool-definition helper;
provider/adapters reorganized to route through native dispatch paths.
* **Chores**
* Dependency updates, removed legacy Google SDK integrations, and
increased front memory allocation.
* **Tests**
* Expanded end-to-end and streaming tests exercising native provider
flows, attachments, and rerank/structured scenarios.

## Summary by CodeRabbit
* **Bug Fixes**
* Improved null-safety, dependency tracking, upload validation, and
error logging for more reliable uploads, clipboard, calendar linking,
telemetry, PDF/theme printing, and preview/zoom behavior.
* Tightened handling of all-day calendar events (missing date now
reported).
* **Deprecations**
* Removed deprecated RadioButton and RadioButtonGroup; use RadioGroup.
* **Chores**
* Unified and upgraded linting/config, reorganized imports, and
standardized binary handling for more consistent builds and tooling.

## Summary by CodeRabbit
* **New Features**
* Enhanced audio/video detection for MP4 files to better distinguish
audio-only vs. video.
* **Dependencies**
* Added MP4 parsing dependency and updated AI provider libraries
(Anthropic, Google, OpenAI, etc.).
* **Bug Fixes**
* Tightened authentication state validation for magic-link/OTP flows.
* Stricter space-join validation to reject invalid client
types/versions.
* Improved transcript entry deduplication and data handling.
* **API**
* Transcript submit payload now requires infos and removes deprecated
url/mimeType fields.

## Summary by CodeRabbit
- **New Features**
- Safer, consistent file downloads with automatic attachment headers and
filenames.
- Smarter MIME detection for uploads (avatars, workspace blobs, Copilot
files/transcripts).
- Sensible default buffer limit when reading uploads.
- **Bug Fixes**
- Prevents risky content from rendering inline by forcing downloads and
adding no‑sniff protection.
- More accurate content types when original metadata is missing or
incorrect.

## Summary by CodeRabbit
* **New Features**
* Error messages for unavailable copilot providers now include specific
model IDs for clearer context.
* Added new detailed error messages for embedding generation failures
specifying provider and error details.
* The API and GraphQL schema have been extended with new error types
reflecting these detailed error cases.
* **Bug Fixes**
* Enhanced error handling to detect and report incomplete or missing
embeddings from providers.
* Added safeguards to skip embedding insertions when no embeddings are
provided, preventing unnecessary processing.
* **Documentation**
* Updated localization and translation keys to support dynamic error
messages with model IDs and provider details.
