## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.

**v2.3 notable constraints:**
- Phase 19 has the highest blast radius (Entra changes) — must be last
- Phase 15 is zero-API-call foundation; unblocks Phase 16 (consolidation) and Phase 18 (ownership) independently
- Group expansion (Phase 17) calls Graph at export time, not at scan time — scan pipeline unchanged
- Auto-take ownership uses PnP `Tenant.SetSiteAdmin` — requires Tenant Admin scope
- App registration must be atomic with rollback; partial Entra state is worse than no state
- [Phase 15]: MakeKey declared internal for test access via InternalsVisibleTo without exposing as public API
- [Phase 15]: LINQ GroupBy+Select for consolidation merge instead of mutable dictionary — consistent with functional codebase style
- [Phase 15-consolidation-data-model]: RPT-04-g test data uses 11 rows (not 10) to produce 7 consolidated rows — plan description had a counting error; 4 unique rows + 3 merged groups = 7
- [Phase 16-01]: Consolidated branch uses early-return pattern inside WriteSingleFileAsync to leave existing code path untouched
- [Phase 16-01]: PermissionsViewModel gets MergePermissions as no-op placeholder reserved for future use
- [Phase 16-report-consolidation-toggle]: BuildConsolidatedHtml is a private method via early-return in BuildHtml — existing code path completely untouched
- [Phase 16-report-consolidation-toggle]: Separate locIdx counter for location groups (loc0, loc1...) distinct from grpIdx for user groups (ugrp0...) prevents ID collision
- [Phase 17]: Static helpers IsAadGroup/ExtractAadGroupId/StripClaims declared internal to enable unit testing via InternalsVisibleTo without polluting public API
- [Phase 17]: Graph client created lazily on first AAD group encountered to avoid unnecessary auth overhead for groups with no nested AAD members
- [Phase 17]: groupMembers optional param in HtmlExportService — null produces identical pre-Phase-17 output; ISharePointGroupResolver injected as optional last param in PermissionsViewModel; resolution failure degrades gracefully with LogWarning
