Direct native CLI launches already inherit their user's shell environment, so recapturing a login interactive shell from the same TTY is unnecessary and can interfere with prompt input on macOS terminals.
The desktop and non-interactive subprocess paths still keep the shell-env bridge because they do not own the user's interactive terminal.
Constraint: Windows was already excluded from terminal shell env capture, which explains why v0.2.8 remained healthy there.
Rejected: Disable terminal shell env capture globally | desktop subprocesses still need the captured login-shell environment.
Confidence: high
Scope-risk: narrow
Directive: Do not re-enable interactive shell env capture for direct TTY launches without a native PTY input regression test.
Tested: bun test src/utils/terminalShellEnvironment.test.ts src/utils/mcpStdioEnvironment.test.ts
Tested: Native PTY smoke confirmed typed characters appear in claude-haha prompt
Tested: SKIP_INSTALL=1 ./desktop/scripts/build-macos-arm64.sh
Not-tested: Full bun run verify was intentionally not completed after user requested only a local macOS build
Desktop launches can inherit a sparse GUI environment, while user runtimes such as nvm and Homebrew are often initialized from shell startup files. Capture a bounded login+interactive shell environment once and reuse it for desktop CLI sessions, scheduled tasks, and MCP stdio startup while keeping explicit MCP PATH and provider-managed env overrides authoritative.
Constraint: macOS app launches may omit user shell PATH and exported runtime variables
Rejected: Patch only MCP stdio | leaves normal desktop sessions and scheduled tasks inconsistent
Confidence: high
Scope-risk: moderate
Directive: Keep provider/OAuth scrubbing after shell env merging when changing child env builders
