+## Implementation report
+
+Implemented critical-path TUI E2E coverage in commit b9f49eee.
+
+Files changed:
+- crates/tui/src/multi_pod.rs: panel mouse wheel events now move selection and emit e2e observer diagnostics without enabling full drag-motion capture.
+- crates/tui/src/single_pod.rs: e2e-test-only canned single-Pod rewind fixture path for real TUI/PTTY driving; preserves production/non-production boundary.
+- tests/e2e/Cargo.toml: disables auto-discovered integration tests and registers panel/rewind only behind the e2e feature.
+- tests/e2e/src/lib.rs: harness support for rewind fixture env isolation, wheel input, event waiting, and forbidden ?1002h/?1003h capture detection.
+- tests/e2e/tests/panel.rs: adds PTY wheel regression coverage and drag-capture failure assertion while keeping existing panel cases.
+- tests/e2e/tests/rewind.rs: adds single-Pod rewind picker/apply/duplicate-Enter regression.
+
+Validation:
+- cargo fmt --check
+- git diff --check
+- cargo test -p yoi-e2e --no-run
+- cargo build -p yoi
+- cargo test -p yoi-e2e --features e2e
+- cargo test -p tui --lib single_pod::tests::rewind
+- cargo test -p tui --lib mouse
+- nix build .#yoi
+
+Additional note:
+- Full cargo test -p tui was also attempted and failed in pre-existing/unrelated tests: multi_pod::tests::orchestrator_launch_context_uses_orchestration_root_for_runtime_workspace and spawn::tests::{profile_choices_include_builtin_and_project_default_marker, profile_choices_use_project_registry_default}. Focused changed-area tui tests passed.
+
+Residual risks:
+- Rewind E2E uses an e2e-test-only canned in-process fixture instead of a provider/socket-backed Pod, intentionally avoiding credentials/network while still exercising the real single-Pod TUI/PTTY path.
+- nix build emitted the expected dirty-tree warning before succeeding.
