The inflight-turn journal can outlive the turn it recorded (reclaim,
reconnect or restart races skip the settle that clears it). On session
resume the fold then re-appends journaled assistant rows to a transcript
that already holds the committed replies, so the conversation ends with
duplicate answers in scrambled order. The fold also carried the stale
entry's streamId onto the resumed state on an idle resume, which kept the
journal entry alive (persistInFlightTurnState only clears when streamId is
null) and re-folded the same tail on every open.
Detect text-level staleness before the append path: when every recoverable
journaled assistant row already exists as committed text in the base
transcript, treat the entry as caught up and clear it. Only keep a stream
target when the resumed session is genuinely running (keepPending), so an
idle resume self-heals instead of re-folding.
The browser-use CLI runs under its own Python (uv tool / uvx), which
can differ from Hermes's venv interpreter. PYTHONPATH/PYTHONHOME
inherited from the agent process point at Hermes's venv
site-packages, and a child interpreter honors them ahead of its own —
so the CLI imported compiled C-extensions (pydantic_core) built for
the wrong interpreter and crashed with ABI mismatch /
ModuleNotFoundError (issues 83427, 84841, 86006, 86104; hits the
desktop backend on py3.14 and any shell exporting PYTHONPATH).
Strip both vars in _base_subprocess_env() — the CLI manages its own
environment and never needs Hermes's import path.
Salvaged from PR 83471 by Benjamin (@n1majne3), the earliest of two
independent fixes (also PR 84022 by @jklance16, PYTHONPATH-only);
regression test covers both vars and preserves unrelated env.
Follow-up to the salvaged #59713 commits: main's ChatPage gained the
PTY resume sanitizer + hydration machinery after the PR was authored, so
the write-callback follow-scroll is applied to the sanitized write path
(term.write(rendered, followScroll)) rather than the raw ev.data writes
the original diff targeted. Also adds the contributor email mapping.
