 ## Implementation Notes
 
 Use `agent_settled` as semantic completion.
 Use process close for resource cleanup after settlement.
+
+Resolved in branch `pi-subagents-tracer-bullet`, commit `4e6baed`.
+Cancellation is idempotent, sends RPC `abort` cooperatively with a bounded grace period, then terminates the child process group on Unix.
+The supervisor now tracks startup and runtime timers, clears timers on terminal states, marks shutdown cancellation as `cancelled`, and ignores later lifecycle events once a terminal state is reached.
+Lifecycle unit tests cover repeated cancel, startup timeout, runtime timeout, process failure, shutdown cleanup, and cancel-after-completion.
+Verification: `nix shell nixpkgs#tsx -c tsx --test modules/agents/pi/extensions/subagents/supervisor.test.ts`, managed extension derivation build, Pi RPC command smoke, live repeated cancel smoke, and `nix flake check`.

 The prototype at `/home/alexion/.local/share/pi-flex-spacer-prototype/pi-monorepo` added `FlexSpacerBottomLayout` in Pi's `dist/modes/interactive/interactive-mode.js` and patched tool lookup in `dist/utils/tools-manager.js`.
 Use it as behavior reference, but implement through the flake-managed Pi package path.
+
+Resolved in commit `5fd8de0` on branch `pi-ui-customization`.
+The Pi module now overrides `pkgs.pi-coding-agent` with `modules/agents/pi/patches/pi-flex-spacer.patch` and `modules/agents/pi/patches/pi-tool-lookup-validation.patch`, assigning the patched package to `programs.pi-coding-agent.package`.
+The patch adds a source-level flex-spacer layout wrapper around flow and pinned prompt-area components, preserving extension footer replacement through a pinned footer container.
+It also enables TUI shrink clearing by default so closing autocomplete clears the temporary menu rows and returns the editor group to the bottom.
+The tool lookup patch makes local `fd`/`rg` binaries count only when `--version` exits successfully.
+Verified with focused package build, built-output inspection, unusable-local-`fd` fallback check, independent review remediation, deployed human visual checks, and `nix flake check`.

+- Verified the patched Pi package builds and its output contains `FlexSpacerBottomLayout` plus NixOS-safe local tool lookup.
+- Verified `/codex-quota` command registration through RPC using the built compact status extension.
+- Ran `nix flake check` successfully.
+- Final deployed checks remain pending because switching the system generation and manual visual checks require explicit consent.

+- Confirmed ordinary `pi` resolves to `/nix/store/ba36x8jb9gr7slx4yq4pz64l5i7sih6h-pi-coding-agent-0.82.1/bin/pi`, whose built output contains `FlexSpacerBottomLayout` and NixOS-safe local tool lookup.
+- Confirmed `~/.pi/agent/extensions/compact-status.ts` is deployed and contains the permanent status widget, hidden footer, context bar, quota bar, and `/codex-quota` command.
+- Confirmed normal RPC launch loads extensions without stderr and exposes the compact status and subagent command surfaces.
+- Confirmed `/codex-quota` returns only normalized non-secret quota details: `Codex quota remaining: weekly 75%, short 75%`.
+- Confirmed deployed tool lookup ignores an unusable local `fd` and falls back to `fd` on `PATH`.
+- The remaining `~/.pi/agent/extensions/compact-status-prototype.ts` is an unmanaged prototype artifact, not part of deployment, and should be removed separately only if the user wants to clean local experiments.
+- Removed the unmanaged prototype extension from `~/.pi/agent/extensions/compact-status-prototype.ts`; a fresh RPC launch now exposes only the permanent `codex-quota` command.
+- Human visual check confirmed the compact status, cwd/branch, model/thinking, context bar, quota bar, hidden footer, bottom-staying prompt during the checked short interaction, normal long-conversation scrolling, and `@` autocomplete.
+- `/codex-quota` was not visually checked by the human in the TUI, but RPC verification confirmed normalized non-secret output.
+- Human visual check confirmed `/` autocomplete works.
+- Closing autocomplete still left space under the editor after switching commit `1d88503`; verification showed the patched TUI default was present, but interactive mode overrides it through `SettingsManager.getClearOnShrink()`, which still defaulted to false.
+- Remediation was updated in commit `5fd8de0` by enabling shrink clearing by default in both the TUI and settings manager, while preserving `PI_CLEAR_ON_SHRINK=0` and explicit settings as opt-outs.
+- Verified the remediation with the patched Pi package build, built-output inspection for both defaults, independent review, `nix flake check`, and deployed human visual confirmation.
+- After switching and relaunching Pi again, human visual confirmation found closing autocomplete now leaves the editor bottom-aligned.
+- Final deployed verification is complete on ordinary `pi`, which resolves to `/nix/store/p2xh13r9f890af4b8jdp60rnld1kbwsl-pi-coding-agent-0.82.1/bin/pi`.
