+## Implementation report
+
+Integration report:
+
+Merged implementation branch into orchestration branch:
+- branch: `impl/00001KV4YAAVY-single-pod-text-selection`
+- implementation commit: `09f5e9d5 feat: add single-pod text selection`
+- merge commit: `3fa52f2c merge: single-pod text selection`
+
+Reviewer result:
+- `approve` recorded from `yoi-reviewer-00001KV4YAAVY`.
+
+Additional integration fix:
+- Because the implementation added a direct `base64` dependency to `crates/tui/Cargo.toml` and updated `Cargo.lock`, `nix build .#yoi --no-link` first failed with stale `package.nix` `cargoHash`.
+- Updated `package.nix` `cargoHash` to the new fixed-output vendor hash:
+  - `sha256-pIDYnbBs3U8Z3IndgH10rirv8/IdFv1WlgwpCbKXy+M=`
+
+Validation in Orchestrator worktree `/home/hare/Projects/yoi/.worktree/orchestration`:
+- Passed: `cargo fmt --check`
+- Passed: `cargo check -p tui --all-targets`
+- Passed: `cargo test -p tui text_selection`
+  - 4 passed
+- Passed: `cargo test -p tui single_pod::tests`
+  - 38 passed
+- Passed: `cargo test -p tui ui::tests::history_rows_mark_text_items_selectable_and_non_text_unselectable`
+  - 1 passed
+- Passed: `git diff --check`
+- Passed after hash update: `nix build .#yoi --no-link`
+
+Notes:
+- OSC52 clipboard acceptance remains terminal/multiplexer dependent; implementation reports write/flush success/failure only.
+- No PTY/E2E validation was run for real terminal selection/copy behavior; focused unit coverage and reviewer inspection covered selection/copy state, extraction, and persistence boundaries.
+- Orchestrator worktree is clean apart from the pending `package.nix`/Ticket integration commit at the time of recording.
+
+Cleanup planned:
+- Stop related coder/reviewer Pods.
+- Remove only child implementation worktree/branch for this Ticket.
