Plan

Read-only investigator: insomnia-cli-owner-investigator-20260531 Classification: implementation-ready

Conclusion:

• Proceed with this ticket as one implementation ticket, but implement in ordered internal phases: move PodRuntimeCommand to client, make tui library-callable, move product CLI/binary ownership to insomnia, then update packaging/docs.

Current code/dependency map:

• crates/tui currently owns the product binary target:
  • crates/tui/Cargo.toml has [[bin]] name = "insomnia" path = "src/main.rs".
  • crates/tui/src/main.rs owns top-level CLI parsing, insomnia pod ... dispatch, insomnia memory lint, and TUI launch.
• crates/insomnia currently has no binary and mostly owns PodRuntimeCommand only.
• crates/pod is already library-only and exposes pod::entrypoint::run_cli_from.
• client, pod, and tests depend on insomnia only for PodRuntimeCommand, creating the wrong dependency direction for the desired architecture.
• package.nix builds -p tui even though the installed command is insomnia.

Recommended architecture:

insomnia -> tui
insomnia -> pod
insomnia -> client
tui      -> client
pod      -> client
client   -> no insomnia
pod      -> no insomnia
tui      -> no insomnia

Implementation plan:

1. Move PodRuntimeCommand from insomnia to client.
   • Prefer client::runtime_command with pub use from client.
   • Update client, pod, and tests to use client::PodRuntimeCommand.
   • Remove insomnia dependency from lower crates.
2. Make tui a library implementation crate.
   • Add crates/tui/src/lib.rs.
   • Move TUI module declarations and TUI launch code behind public library API.
   • Expose narrow API such as LaunchOptions, LaunchMode, launch(...).
   • Keep terminal setup/teardown in tui because it owns terminal behavior.
   • Remove product CLI parsing and pod/memory lint dispatch from tui.
3. Make insomnia own product CLI/binary.
   • Add crates/insomnia/src/main.rs.
   • Move top-level CLI parser/dispatch from tui to insomnia.
   • Route pod to pod::entrypoint::run_cli_from("insomnia pod", args).
   • Route memory lint from insomnia, not tui.
   • Route normal TUI modes to tui::launch(...) with a typed runtime command.
4. Update packaging/docs.
   • Remove [[bin]] name = "insomnia" from tui.
   • Make package.nix build -p insomnia.
   • Update active docs/dev commands from cargo run -p tui -- ... to cargo run -p insomnia -- ....

Important constraints:

• Do not introduce pod -> insomnia or tui -> insomnia.
• Do not keep compatibility for cargo run -p tui -- ....
• Do not reintroduce insomnia-pod, INSOMNIA_POD_COMMAND, or the separate INSOMNIA_POD_RUNTIME_COMMAND; that dev override is tracked by dev-pod-runtime-command-env.
• Do not change Pod protocol/profile/manifest semantics.
• Avoid broad TUI refactoring beyond making the crate library-callable.

Critical risks:

• tui/src/main.rs is large and mixes CLI, terminal lifecycle, event loop, key handling, and tests. Keep changes mechanical and avoid unrelated module cleanup.
• Parser tests should move to insomnia; TUI behavior tests should remain with tui.
• memory_lint is headless product CLI code and should not remain routed through TUI.
• --help behavior needs explicit handling because the old parser mostly ignored unknown flags.

Validation:

• cargo fmt --check
• cargo check -p client -p pod -p tui -p insomnia
• cargo test -p client
• cargo test -p pod
• cargo test -p tui
• cargo test -p insomnia
• CLI smoke:
  • cargo run -p insomnia -- --help
  • cargo run -p insomnia -- pod --help
  • cargo run -p insomnia -- memory lint --help
  • cargo run -p insomnia -- --session not-a-uuid
• Dependency ownership checks:
  • cargo tree -p client -e no-dev --depth 1
  • cargo tree -p pod -e no-dev --depth 1
  • cargo tree -p tui -e no-dev --depth 1
  • cargo tree -p insomnia -e no-dev --depth 1
• If packaging changed:
  • nix build .#insomnia
  • ./result/bin/insomnia pod --help
  • test -x ./result/bin/insomnia
  • test ! -e ./result/bin/insomnia-pod
• ./tickets.sh doctor
• git diff --check
• rg "cargo run -p tui" docs README.md crates package.nix flake.nix
