Wires the salvaged search helpers into the shared curses menu driver and
turns on type-to-filter for the CLI model pickers (the 100+ model lists
that previously required scrolling).
- Search lives in the shared `_run_curses_menu` driver behind a
`searchable` flag + `search_labels`, so both `curses_radiolist` and
`curses_single_select` get it without per-menu duplication. `/` opens
the filter, BACKSPACE edits, Ctrl+U clears, ESC clears the filter then
cancels. Returned values are always original item indices.
- `_filter_indices` RANKS matches (best-first) via a Python port of the
TS scorer in ui-tui/src/lib/fuzzy.ts and web/src/lib/fuzzy.ts. The port
is byte-identical in score: same per-char bonuses, prefix (+8) and
exact (+20) bonuses, camelCase/word-boundary detection (matching on the
lowercased target, boundary on the original case), and the -len*0.01
length tiebreak — so the CLI, TUI, and WebUI rank results identically.
A cross-language parity test pins the exact scores.
- `_prompt_model_selection` (the canonical picker across the model flows)
and the custom-provider model list pass `searchable=True`.
- Split `_decode_menu_key` out of `read_menu_key` so the search loop can
peek the raw key (catch `/`) before nav decoding.
- ESC during active search now clears the query (restores the full list)
so a no-match filter can't strand the user; printable-key capture is
restricted to ASCII to avoid Latin-1 mojibake.
- Update two setup-menu tests whose mock signatures predate the new
`searchable` kwarg; add ranked-scorer + parity + state-machine tests.
The setup provider->model sub-menu (and three sibling pickers) used
simple_term_menu.TerminalMenu, whose ESC and arrow-key handling was
unreliable across terminals — notably ESC failed to back out of the
model selection list on terminals that emit raw escape sequences (e.g.
Ghostty). The codebase already notes simple_term_menu 'conflicts with
/dev/tty' and causes 'ghost-duplication rendering', and a prior attempt
to migrate these (closed PR) confirmed the same root cause.
Route all four single-select pickers through the shared, already-hardened
curses_radiolist (which decodes raw CSI/SS3 escape sequences and handles
ESC consistently, fixed in #35776):
- auth.py _prompt_model_selection — model picker; the pricing column
header and the unavailable-models block are passed as the radiolist
description so they survive the curses screen clear. ESC now cancels.
- main.py _prompt_reasoning_effort_selection — reasoning-effort picker.
- main.py _model_flow_named_custom — named custom-provider model picker.
- main.py _remove_custom_provider — provider-removal picker.
simple_term_menu is no longer imported anywhere (only stale comments
referenced it; one in setup.py is corrected). The numbered-input
fallbacks are unchanged and still trigger on curses errors / non-TTY.
Tests: updated test_terminal_menu_fallbacks / test_reasoning_effort_menu
/ test_custom_provider_model_switch / test_model_provider_persistence to
drive the fallback via curses_radiolist errors instead of breaking
simple_term_menu. New test_setup_menu_curses_migration.py asserts each
picker routes through curses_radiolist, ESC cancels, and the pricing
header is preserved. Net -147/+183 (mostly the new test file; production
code shrinks by removing TerminalMenu boilerplate).
