+| LOC (lib) | 7,773 | TBD |
+| Tests | 89 | TBD |
 
 ## Accumulated Context
 
 ### Decisions
 
-All v1.0 decisions are recorded in PROJECT.md Key Decisions table with outcomes.
+| Decision | Rationale |
+|----------|-----------|
+| Calendar strip replaces daily plan home screen | v1.1 goal per PROJECT.md — not additive, the stacked overdue/today/upcoming sections are removed |
+| Phase 5 before Phase 6 and 7 | Calendar strip is the primary UI surface; history and sorting operate within or alongside it |
+| Phase 6 and 7 both depend on Phase 5 only | History and sorting are independent of each other — could execute in either order |
+| HIST-01 and HIST-02 in same phase | Data layer (HIST-01) is only 1-2 DAO additions; grouping with the UI (HIST-02) keeps the phase coherent |

 ### Blockers/Concerns
 
-None.
+- The existing HomeScreen (daily plan with overdue/today/upcoming) will be replaced entirely in Phase 5. Verify no other screen references the daily plan provider before deleting it, or migrate references.
+- CAL-05 (overdue carry-over with color accent) requires a query that returns tasks by their original due date relative to a selected day — confirm the existing DailyPlanDao can be adapted or a new CalendarDao is needed.
