Main's rewritten test_tui_npm_install.py tests call _make_tui_argv expecting
the Ink/npm flow unconditionally; with the dual-engine dispatch merged in,
_resolve_tui_engine() auto-selects opentui whenever ui-opentui/dist is built
in the repo, routing the call away from the path under test (first subprocess
became 'node --version' instead of 'npm run build'). Pin the engine to ink
via an autouse fixture, mirroring the existing pinning precedent in
test_tui_resume_flow.py.
hermes --tui launches the native OpenTUI engine (Bun) when
HERMES_TUI_ENGINE=opentui (env) or display.tui_engine=opentui (config);
Ink stays the default and the shipping path is untouched.
- _resolve_tui_engine() (env > config > ink); refuses opentui on
Windows/Termux (no Bun) -> falls back to ink with a notice.
- _make_opentui_argv() -> [bun, src/entry.real.tsx] (no build step).
- _bun_bin() with HERMES_BUN override.
- Branch at top of _make_tui_argv BEFORE _ensure_tui_node (Bun-only host
must not bootstrap Node).
- Gate _launch_tui NODE_OPTIONS/--max-old-space-size on engine==ink (Bun
is JSC; the V8 flag errors/ignores).
Verified end-to-end via tmux: real hermes --tui -> Bun -> OpenTUI ->
real Python gateway streamed a real reply. No-flag default still ink.
Lift the post-loop finalization tail out of run_conversation into
agent/turn_finalizer.py:finalize_turn. Behavior-neutral; run_conversation
4204 -> 3846 LOC, conversation_loop.py 4578 -> 4220.
The region (everything after the main tool-calling while loop): budget-exhaustion
summary, trajectory save, session persist, turn diagnostics, response transforms,
result-dict assembly, steer drain, and the memory/skill review trigger. Lifted
verbatim into a synchronous single-return free function; the 12 post-loop locals
it reads are passed as keyword args and the assembled result dict is returned to
run_conversation (which returns it to the caller). All agent.* side effects fire
exactly as before.
Imports: os + _summarize_user_message_for_log at module top; logger lazy from
agent.conversation_loop (preserves the gateway... err 'agent.conversation_loop'
logger name, no import cycle).
Validation: 1609/1609 tests/run_agent/ pass; live PTY agent turn PASS.
