Streamed responses no longer insert real newlines at terminal width —
logical lines are emitted whole and the terminal soft-wraps them, so
highlight-copy rejoins the full line (emulators only keep linebreaks
the app actually printed). This is the CLI equivalent of the TUI's
selection copy, which reads logical source lines from its screen
buffer. TTFT perception is preserved by mirroring the unfinished
line's tail into the spinner status text instead of chunk-printing.
/copy now prefers OSC 52 when running over SSH (SSH_CONNECTION /
SSH_TTY / SSH_CLIENT) — native tools there write the REMOTE clipboard,
which is never what the user wants. The CLI's OSC 52 writer also gains
tmux/screen DCS passthrough wrapping, mirroring the TUI's
wrapForMultiplexer. Fixes#31528 for the CLI surface.
Sabotage-verified: restoring the old chunk emitter fails 3 of the new
tests (hard-wrap detection, spinner mirror, unbreakable-run split).
Follow-up to #59332 targeting the remaining PERCEIVED first-token latency
(the wire streaming was already per-token; these fix what the user sees):
1. display.show_reasoning default ON. On thinking models the reasoning
phase streams for tens of seconds; with the display off users stare
at a spinner the whole time and read it as a stall. Flipped in
DEFAULT_CONFIG, load_cli_config defaults, tui_gateway raw-YAML
fallbacks, and the hermes setup status line (all four read sites kept
in sync). Gateway per-platform defaults intentionally stay off —
messaging chats shouldn't fill with thinking text. /reasoning hide
still turns it off and persists.
2. Response box force-flushes long partial lines. _emit_stream_text only
painted on newline, so a response opening with a long paragraph
stayed invisible until the first \n — seconds of blank box. Now
partial lines wrap at terminal width and paint as tokens arrive
(mirrors the reasoning box's 80-char force-flush that existed since
day one). Table blocks remain batch-aligned; no content loss at wrap
boundaries (regression tests added).
3. hermes_time timezone resolution uses read_raw_config (mtime-cached +
libyaml C loader) instead of a raw yaml.safe_load of config.yaml
(~110-140ms measured) inside the FIRST system prompt build. First
build drops 320ms -> ~155ms on a 200-skill install.
4. Stale docs: configuration.md (en+zh) still documented the 70%/90%
[BUDGET WARNING] tool-result injections. Those were removed in April
2026 (c8aff7463) precisely because they hurt task completion; current
behavior is exhaustion-message + one grace call, no mid-loop
injection, no cache impact. Docs now describe reality.
Verified: token-count compression decisions already use API-reported
last_prompt_tokens (rough estimators are preflight-only and cost ~1.7ms
even on 1.7MB histories — not worth touching).
