 # V1 Block 08 — Today Timeline State
 
-Status: In progress — Chunks 8.1, 8.2, and 8.3 complete
+Status: Complete
 
 Purpose: Prepare domain/view-state data for the Today timeline without building full Flutter UI yet unless explicitly requested.
 
@@ -149,6 +149,15 @@ Acceptance criteria:
 - Mapping rules are tested without depending on a UI framework.
 - Existing scheduling, backlog, locked-block, and task-action tests still pass.
 
+Completed:
+
+- Expanded timeline regression coverage for all task-type background tokens.
+- Added exhaustive reward icon token coverage for every reward level plus `notSet`.
+- Added exhaustive difficulty icon token coverage for every difficulty level plus `notSet`.
+- Added focused compact-mode reduced-output regression coverage.
+- Confirmed existing timeline tests cover flexible duration display, required explicit time display, reveal-gated locked overlays, locked overlay category, project color tokens, and flexible quick actions.
+- Verified with `dart format lib test`, `dart analyze`, and `dart test`.
