Research and design for adding OpenCode session support to claude-karma. Covers data model mapping (SQLite → Pydantic), SessionSource abstraction layer, module structure, and frontend source filter/badge components. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Rewrote the design document based on actual OpenCode database analysis: - Corrected schema from 4 tables to 8 (added todo, permission, session_share, control_account) - Documented JSON blob architecture (message.data, part.data) with real examples - Expanded part types from 7 to 11 (added step-start/finish, patch, compaction, agent, retry) - Added feature parity matrix: 13 full, 7 partial, 10 Claude-Code-only, 6 OpenCode-only - Added field-level data mappings for all models - Added timeline event mapping for all 11 part types - Added SQLite metadata DB integration strategy - Resolved data_source vs session_source naming conflict - Added 5-phase implementation plan with acceptance criteria Passed Critic re-review (all 12 original gaps addressed).

- Add complete Router Classification table (17/17 routers classified) - Add Verified Data Gaps section with real DB findings (git branches, cost always $0, 6/12 part types exist, plan mode is message-level) - Expand Feature Parity Matrix with 7 new rows (plans, agent analytics, subagent detail, archived prompts, skills browser, live sub-statuses) - Add Derived Metrics with verified SQL formulas and NULLIF guards - Correct Timeline Event Mapping with verification status column - Update Module Structure with all 17 routers - Fix part type count (11 → 12), reconcile plans.py terminology, note SCHEMA_VERSION bump for metadata DB migration Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
