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.
CI caught tests/cli/test_cli_new_session.py asserting that /new keeps
the old session row when conversation history exists in memory. The
live transcript is authoritative: a session whose messages haven't
flushed to the DB yet (or whose flush failed) must not be pruned.
Guard _discard_session_if_empty on self.conversation_history and pin
the behavior with a test.
Port from google-gemini/gemini-cli#27770: starting the CLI and
immediately quitting (or rotating with /new, /clear) left an empty
untitled session row behind. These ghost rows pile up in /resume,
`hermes sessions list`, and the in-chat recent-sessions browser.
- SessionDB.delete_session_if_empty(): transactional check-and-delete
that only removes rows with no messages, no title, and no child
sessions (delegate subagent parents are preserved). Also removes
on-disk transcript files via the existing _remove_session_files.
- HermesCLI._discard_session_if_empty(): thin wrapper, wired into the
cli_close shutdown path and the new_session() rotation path.
Skipped when /exit --delete already handles removal.
Unlike the one-shot prune_empty_ghost_sessions migration (TUI-only,
24h-old rows), this prevents new ghost rows from accumulating at the
moment they would be created.
