# Stage 1 Task
## 0. Header
- Task ID: TASK-20260222-001
- Title: Define identity provider boundaries in thalos-dal
- Status: Planned
- Priority: P1
- Target Repo: thalos-dal
- Target Branch: feature/thalos-dal-001
- Related Master Plan: plan/master-stage1-structural-normalization-2026-02-22.md
- Related Mini Plan: plan/thalos-dal-mini-plan.md
## 1. Goal (What and Why)
### What
- Map user, role, permission, module, and tenant provider ownership
- Document aggregate-specific persistence responsibilities
### Why
- Identity DAL requires strict provider ownership by aggregate
## 2. Scope
### In Scope
- Provider ownership map by identity aggregate
### Out of Scope
- Service orchestration concerns
## 3. Constraints (Non-Negotiable)
- Stage 1 planning only. No implementation changes.
- Do not modify any file under legacy.
- Do not run repo provisioning or CI generation.
- Follow the approved architecture boundaries and protocol policy.
- Keep identity abstractions inside Thalos repositories.
## 4. Documentation Requirement
- [ ] Capture planning decisions clearly for handoff.
- [ ] Identify documentation and diagram updates expected in later stages.
## 5. Context
- This task derives from plan/thalos-dal-mini-plan.md.
- This task must remain decision-focused and implementation-ready.
## 6. Proposed Approach
- Define provider boundaries and aggregate ownership rules
## 7. Execution Steps
1. Review legacy evidence relevant to this task scope.
2. Define target boundary decisions and contract implications.
3. Record risks, dependencies, and compatibility notes.
4. Produce clear handoff guidance for implementation stage.
## 8. Acceptance Criteria
- [ ] Decisions are explicit, scoped, and actionable.
- [ ] Ownership boundaries are unambiguous.
- [ ] Protocol policy alignment is explicit where applicable.
- [ ] No forbidden Stage 1 actions were performed.
## 9. Testing Plan
### Unit Tests
- Not applicable for Stage 1 planning artifacts.
### Validation
- Ensure consistency with master plan and mini plan.
## 10. Definition of Done
- [ ] Task content is complete and consistent with other task files.
- [ ] References to master and mini plans are correct.
- [ ] Handoff notes are clear enough for immediate implementation.
## 11. Risks and Questions
- Risk: boundary drift during implementation.
- Mitigation: enforce repo intent metadata and mini plan ownership.
## 12. Handoff Notes
- Preserve approved constraints exactly.
- Implementers should execute this task only after reading master and mini plans.
