Changes

Streaming Chat Endpoint (c826279)

New /ml/chat/stream SSE endpoint in dev/ml/gateway/chat.py
Multiplexes responses from Gemini API and on-prem Ollama (via model proxy)
Each SSE event tagged with {"provider": "gemini", "delta": "...", "done": false}
Clients can demux and render multiple provider responses in parallel
Added Bruno tests for the chat API

Project Sync Endpoint (7d21cde)

New POST /v1/sync-project on the data service
Fetches full project tree (tasks, subtasks, items, specialties) from Supabase
Generates markdown with YAML frontmatter following LocationModels convention
Saves as projects/{slug}.md asset in location SQLite DB + S3 blob
Backend list_assets now supports projectId="all" for cross-project discovery
Extracted shared modules: core/supabase_queries.py, core/markdown_gen.py, core/location.py
Refactored ML scraper to use shared query functions

Planning Context in Sync (4002ee3)

Project markdown now includes a "Planning Context" section
Embeds Gemini-generated clarifying questions and user answers from ai_metadata
Gives on-site agents full visibility into the refinement conversation

Deduplicate list_assets (f35c4c1)

When projectId="all", uses SQL window function to return only the most recent asset per unique file_name
Prevents iOS DataSyncService from downloading duplicate copies (e.g., manifest.md appearing 3x under different project IDs)
Fixes memory exhaustion and app crashes on iOS

Bruno Test Cleanup (1d154c4)

Chunked upload test now completes full flow: init -> upload chunk (final=true) -> verify -> delete
Data Bridge test deletes test-photo.jpg after download
Reduced chunked test from 10MB to 1KB (1 chunk) for speed
Eliminates orphaned assets that caused 500 errors on missing S3 blobs

Bruno Environments (34ecddb)

All environments (dev, beta, jh, main, cc, fl, rk) now use the same real Supabase test IDs
Tests are reproducible across all environments
