[Programcode]

Outcome

• adds shared evidence with provenance and citations
• adds opt-in team AI threads with server-owned, idempotent generation
• carries explicit workspace context through Generate, Attack, Ask, Flowchart, Crossfire, and Sparring
• persists resumable practice and explicitly shared private results without leaking personal sources, prompts, chat history, or Sparring drafts

Tested journey

• create shared evidence and a named thread
• run and reject/accept a reviewable AI rewrite
• continue Crossfire and Sparring after reload
• verify stale document epochs, revocation, and duplicate thread requests fail closed

Checks

• typecheck
• 98 focused client/store tests
• 240 Edge tests
• database and authenticated browser gates run in CI

Limits

• browser AI uses a fixture response; no live provider claim
• no staging run, remote migration, or backend deployment is authorized by the implementation plan

📝 Walkthrough

Walkthrough

The change adds workspace evidence, shared AI threads, workspace-scoped tool requests, artifact persistence, document projections, and workspace-aware tool flows. It also adds authorization, session isolation, persistence, integration, SQL, and end-to-end tests.

Changes

Workspace collaboration

Layer / File(s)	Summary
Workspace persistence and snapshot projections services/collaboration/..., supabase/migrations/..., supabase/tests/...	Workspace sources, threads, messages, artifacts, RPCs, policies, generation state, and document text projections are added. Collaboration snapshots persist and backfill validated text projections.
Workspace context and AI authorization src/lib/workspace/..., src/lib/ai/client.ts, supabase/functions/_shared/..., supabase/functions/ai/index.ts	Workspace context is validated and loaded from durable data. AI requests exclude private sources and custom prompts, use authorized workspace context, and settle thread generations.
Workspace practice interface and tool flows src/components/features/workspace/..., src/pages/..., src/lib/stores/sparring-store.ts, src/locales/*.json	The workspace UI supports evidence, citations, shared threads, practice tools, rewrite suggestions, artifact inspection, workspace-scoped tool pages, and private-session restoration.
Workspace behavior validation e2e/..., src/test/..., supabase/functions/_shared/...	Tests cover shared evidence and threads, AI request isolation, context validation, proposal serialization, session restoration, authorization, artifact persistence, and teammate reload recovery.
