* fix(tui): delineate assistant responses from details
Add a muted Response marker before assistant text when thinking/tool details are visible so reasoning and final output do not visually run together.
* fix(tui): account for response separator height
Keep virtual transcript estimates aligned with the new response separator and avoid allocating trimmed copies of long assistant text.
* fix(tui): gate response separator estimate on details
Only add response-separator height when assistant details actually render, and use a non-allocating body-text check.
* fix(tui): skip empty detail height estimates
Do not add virtual transcript height for assistant details when no thinking or tool detail UI will render.
* fix(tui): estimate details by section visibility
Pass resolved thinking/tool visibility into virtual height estimates so hidden detail sections do not reserve response-separator rows.
Two independent bugs caused the slash-command autocomplete to render
`/goal` as `/goa` (and `/gquota` as `/gquot` for that matter) in the TUI:
1. `tui_gateway/server.py` was forwarding `c.display` from
prompt_toolkit's `Completion` straight into the JSON-RPC payload.
prompt_toolkit normalizes `display=` into `FormattedText` (a `list`
subclass), so the wire format became `[["", "/goal"]]` instead of
the `string` that `CompletionItem.display` in the TUI declares.
`meta` already went through `to_plain_text` — `display` did not.
2. The dropdown row in `appOverlays.tsx` used `flexDirection="row"`
with the display `<Text>` and the (very long) meta `<Text>` as
siblings. When the meta overflows the row width, Ink/Yoga shrinks
the *first* column by one cell, lopping the trailing character off
the command name. `/goal` triggers it reliably because its meta
string is the longest of any built-in command (description +
embedded `[text | pause | resume | clear | status]` usage hint).
Wrapping the display column in `<Box flexShrink={0}>` keeps it at
its natural width and lets the meta wrap or truncate instead.
* fix(tui): refresh virtual transcript on viewport resize
Notify scroll subscribers when ScrollBox viewport bounds change and key virtual-history updates on viewport height so resize/keyboard changes remount the tail rows instead of leaving stale spacers visible.
* test(tui): isolate viewport-height remount regression
Keep the resize delta below the virtual history scroll quantum so the regression test specifically depends on viewport height entering the snapshot key.
* test(tui): clarify virtual history resize snapshot
Update the resize regression and comments so the test specifically guards viewport-height changes in the virtual-history snapshot key.
* docs(tui): clarify scrollbox subscription signals
Document that ScrollBox subscribers are notified for renderer-computed viewport and content bound changes, not only imperative scrolls.
* fix(tui): recompute virtual tail after width resize
Avoid preserving a frozen virtual transcript range when wrapped rows shrink enough that the old tail window no longer covers the viewport.
* fix(tui): preserve transcript tail across resizes
Wraps + heights are column-dependent, so a width change must remeasure
every row and the renderer must repaint the full viewport.
- Key virtualRows on cols so React remounts wrapped rows on resize.
- Snap back to bottom after sticky-mode resize once React rerenders.
- Reserve a scrollbar + gap column in transcriptBodyWidth (non-termux).
- Full repaint on any viewport height change (was: shrink-only).
- ScrollBox scrollHeight uses deepest child bottom so sticky-bottom
math can reach the real final rendered row after reflow.
- DECSTBM fast-path now requires full container rect match.
* feat(tui): responsive banner tiers
Terminals can't scale glyphs, so the banner now picks a layout per
column width instead of always rendering the full 101-col logo:
- Wide (>= logo width): full ASCII logo + tagline.
- Mid (>= 58 cols): centered rule banner that expands with viewport.
- Narrow (>= 34 cols): brand line + tagline, both width-aware.
- < 34 cols: hidden.
SessionPanel surfaces model/cwd/sid inline when the hero column is
hidden, so narrow layouts don't lose that info. Logo width constants
derive from the art itself.
* fix(tui): re-check sticky inside resize debounce + document remount
Addresses Copilot review on PR #31077:
- onResize now re-checks isSticky() inside the 100ms timer so manual
scrolls during the debounce window don't get snapped back to tail.
- Comment on the virtualRows cols-keying calls out the deliberate
trade-off: per-row local state (e.g. systemOpen) resets on resize so
yoga can remeasure off live geometry. The hook's scale-by-ratio path
is too approximate for mixed markdown widths.

* fix(tui): ignore late thinking deltas after completion
Prevent stale reasoning events from repainting the TUI status after a turn has already completed and the UI is idle.
* test(tui): restore timers after thinking delta assertion
Keep fake timer cleanup in a finally block so assertion failures cannot leak timer mode into later tests.
* fix(tui): log parent gateway lifecycle exits
Add parent-side breadcrumbs for TUI gateway shutdown and transport exits so future backend EOF/SIGTERM reports identify the parent action that caused them.
* chore(tui): retrigger lifecycle logging checks
Retry transient GitHub checkout failures on the lifecycle logging PR.
* fix(tui): commit composer input bursts immediately
Salvage the WSL/terminal multi-character input burst fix with focused regression coverage so delayed pseudo-paste buffers cannot reorder later edits.
* fix(tui): keep newline input bursts on paste path
Preserve paste handling for multi-character chunks with newlines while keeping repeated printable key bursts on the immediate composer path.
* refactor(tui): share composer frame batch interval
Use one frame-sized batching constant for parent updates, local renders, and input burst flushes.
* fix(tui): surface verbose tool details
Emit redacted structured verbose args/results to the TUI so /verbose verbose can show full tool detail without reopening stdout, and fail closed if redaction is unavailable.
Salvages #29011.

* feat(tui): make display.mouse_tracking pick which DEC modes to enable
Previously the boolean flag was all-or-nothing across modes 1000+1002+1003+1006.
Inside tmux, mode 1003 (any-motion) makes every mouse cross of the prompt row
fire a clipboard probe that surfaces as "No image in clipboard" — sometimes
dozens in a row. Disabling tracking entirely killed scroll-wheel scrolling too,
since tmux's own scrollback is preempted by the alt-screen TUI.
`display.mouse_tracking` (and `/mouse <preset>`) now accepts `off | wheel |
buttons | all` in addition to the legacy booleans. `wheel` is 1000+1006:
scroll wheel + click only, no drag, no hover — the tmux-friendly subset.
`buttons` adds 1002 for drag-to-select. `all` (= legacy `true`) keeps the
hover-driven UI (scrollbar paginate-on-hover, link mouseenter, etc.).
* fix(tui): repaint + sync mouse mode when display.mouse_tracking changes
Two interacting bugs left the TUI blank when `display.mouse_tracking`
switched at runtime (config edit, /mouse <preset>):
1. AlternateScreen's effect re-runs on every `mouseTracking` change,
tearing down and re-entering the alt screen. After re-entry, ink's
frame buffers are reset by `resetFramesForAltScreen()` but nothing
schedules the follow-up render — the alt screen sits blank until
some other state change happens to trigger one. Add a
`scheduleRender()` in `setAltScreenActive`'s active=true branch so
the freshly-entered alt screen gets a full repaint immediately.
2. `setAltScreenActive` early-returns when `active` hasn't changed,
which silently drops a `mouseTracking` change if the cleanup→setup
pair somehow leaves `altScreenActive` already true. Call
`setAltScreenMouseTracking` explicitly from the AlternateScreen
effect so the in-memory mode and terminal DECSET sequence stay in
sync regardless of how `setAltScreenActive` resolved (the call is a
no-op when the mode is unchanged).
* fix(tui): address copilot review #4341269705
- tui_gateway/server.py: drop the never-referenced _MOUSE_TRACKING_MODES
frozenset (comment #3284802434). _MOUSE_TRACKING_ALIASES already
centralizes the canonical preset set via its values; the separate
constant added no behavior.
- tests/test_tui_gateway_server.py: update the existing
test_config_mouse_uses_documented_key_with_legacy_fallback to assert
the new preset strings ('all'/'off' instead of 'on'/'off',
display.mouse_tracking persisted as 'all' instead of True) and add
test_config_mouse_accepts_preset_strings_and_aliases covering /mouse
set with wheel/click/unknown (comment #3284802453). The on/off legacy
config.set return shape was an implementation detail of the boolean
flag, not a stable API — the slash command, gateway help text, and
docs all advertise the preset values now.
- ui-tui/packages/hermes-ink/src/ink/ink.tsx: schedule a render at the
end of reenterAltScreen() (comment #3284802461). Mirrors the same fix
in setAltScreenActive() from ece0a2f4c — without it, SIGCONT/resize
self-heal/stdin-gap re-entry leaves the alt screen blank because
every caller returns early after invoking us.
* fix(tui): address copilot review #4341308478 round 2
- ui-tui/src/config/env.ts (comment #3284837577): the precedence
comment was misleading. Actual behavior on origin/main is
HERMES_TUI_MOUSE_TRACKING (explicit override) > Termux default >
HERMES_TUI_DISABLE_MOUSE legacy kill-switch. This is preserved from
main; the only change here was the wrong comment that claimed
DISABLE_MOUSE kept kill-switch semantics. Rewrote the comment block
to document the actual precedence ladder.
- tui_gateway/server.py /mouse set (comment #3284837607): replaced
'str(value or "").strip().lower()' with the explicit None idiom
already used for /indicator, so programmatic callers can pass 0 /
False and have them route through _MOUSE_TRACKING_ALIASES → 'off'
instead of collapsing to '' and triggering the toggle path.
- ui-tui/packages/hermes-ink/src/ink/components/AlternateScreen.tsx
(comment #3284837620): always prepend DISABLE_MOUSE_TRACKING before
enableMouseTrackingFor(...) on mount. Otherwise selecting
'wheel'/'buttons' from a state where DEC 1003 was already asserted
(crash, another app, debugger) would silently leave hover on. Also
unconditionally DISABLE on unmount so a crash mid-mount can't leak
DEC modes back to the host shell.
* chore(release): map nat@nthrow.io to @nthrow for #26681 salvage
* fix(tui): drop redundant setAltScreenMouseTracking in AlternateScreen
Copilot review #4341356637 (comment #3284880417). The explicit
setAltScreenMouseTracking(mouseTracking) after setAltScreenActive(true,
mouseTracking) was defensive paranoia added in the previous fix commit
that's not actually reachable in practice:
- React's cleanup always runs before the next setup, so on any prop
change (mouseTracking or writeRaw) the cleanup sets active=false
first. Setup then sees active was false and applies the new mode
via setAltScreenActive without early-returning.
- On the impossible 'active stayed true' path, the writeRaw above has
already sent DISABLE_MOUSE_TRACKING + enableMouseTrackingFor(newMode)
to the terminal, so the in-memory mode would lag but the visible
state is already correct.
Removing the redundant call means a single DEC sequence per mount.
If the 'active stayed true' path ever manifests in practice, the
right fix is in setAltScreenActive (track mode regardless of the
active early-return), not here.
* fix(tui): always DISABLE before enableMouseTrackingFor in ink.tsx
Copilot review #4341379994 (comments #3284900825, #3284900840,
#3284900852). Three remaining call sites in ink.tsx still re-enabled
mouse tracking without first sending DISABLE_MOUSE_TRACKING:
- handleResize alt-screen recovery (line ~577)
- reassertTerminalModes stdin-gap re-assertion (line ~1351)
- reenterAltScreen SIGCONT/resize/stdin-gap self-heal (line ~1408)
For 'wheel'/'buttons' presets, omitting DISABLE leaves any externally-
asserted DEC 1003 (other apps, prior crash, tmux state) still active
and the hover-free preset silently has hover on. DISABLE_MOUSE_TRACKING
is idempotent and safe to send unconditionally — it resets all four
modes. Matches the pattern already in setAltScreenMouseTracking and
the AlternateScreen mount path.
* fix(tui): always DISABLE before enableMouseTrackingFor in exitAlternateScreen
Copilot review #4341452823 (comment #3284959762). exitAlternateScreen()
was the last call site in ink.tsx still re-enabling mouse tracking
without DISABLE first. Editors (vim/nvim/less) and tmux can leave
DEC 1003 hover asserted across the handoff back; without DISABLE,
'wheel'/'buttons' presets silently kept hover on after the editor
quit. Now all five enableMouseTrackingFor() call sites in ink.tsx
prepend DISABLE_MOUSE_TRACKING — handleResize, reassertTerminalModes,
reenterAltScreen, setAltScreenMouseTracking, exitAlternateScreen.
* fix(tui): add defensive default to enableMouseTrackingFor switch
Copilot review #4341485231 (comment #3284979323). TS exhaustive switch
returns string per the type system, but a JS caller / corrupted config
/ hot-reload-in-dev could reach the function with an unknown value at
runtime. Without a default, that path returns undefined which then
concatenates as the literal string 'undefined' into the terminal byte
stream — visibly garbling output. Treat unknown as 'off' (no DEC
sequences) so the worst case is silent input loss rather than a
wrecked screen.

`splitReasoning()` strips paired `<think>…</think>` blocks first, then runs
an unclosed-trailing regex to catch reasoning that hasn't yet streamed its
closer. That second regex was unanchored and greedy:
new RegExp(`<${tag}>([\\s\\S]*)$`, 'i')
So any literal `<think>` somewhere in prose — a model quoting the tag, a
code example, or a stream-mid-tag before the closer arrives — consumed
every paragraph after it to EOF. User-visible symptom: "TUI eats last
paragraph of output," both during streaming and on settled turns.
Real reasoning streams always lead the message (that's the only place an
unclosed opener can legitimately appear during streaming). Anchor the
regex to `^\s*` so mid-prose mentions of the tag are preserved.
Empirical repro before the fix:
splitReasoning('final answer paragraph one.\n\n<think>internal note\n\nfinal answer paragraph two.')
→ text: 'final answer paragraph one.' ← paragraph two GONE
After:
→ text: 'final answer paragraph one.\n\n<think>internal note\n\nfinal answer paragraph two.'
Updated the existing trailing-unclosed test to lead with `<think>` (the
real-world shape) and added a regression test pinning the mid-text case.
ui-tui type-check clean, 808/808 vitest pass.
* fix(lint): skip per-file shell linter when LSP will handle the file
`_check_lint` ran `npx tsc --noEmit FILE.ts` after every `.ts`/`.tsx`
edit. `tsc` ignores `tsconfig.json` when given an explicit file argument
(documented quirk) and defaults to no-lib / ES5, so every ES2015+ stdlib
reference reports as missing:
- `Cannot find global value 'Promise'`
- `Cannot find name 'Map' / 'Set' / 'ReadonlySet' / 'Iterable'`
- `Property 'isFinite' does not exist on type 'NumberConstructor'`
- `Module 'phaser' can only be default-imported using esModuleInterop`
- `import.meta is only allowed when --module is es2020+`
On real TypeScript projects this floods the `lint` field on
WriteResult / PatchResult with up to 25K tokens of false positives
per edit. The delta filter in `_check_lint_delta` is supposed to mask
them, but a tiny edit shifts line numbers and every phantom resurfaces
as "introduced by this edit". The result is a 1MB+ phantom-error dump
on every patch that eats the agent's context budget. Same shape for
`.go` (`go vet` outside a module) and `.rs` (`rustfmt --check` outside
a Cargo project).
PR #24168 added an LSP tier on top of this — real `tsserver` / `gopls`
/ `rust-analyzer` diagnostics surface in the separate `lsp_diagnostics`
field. But the broken shell linter kept running underneath, so the
phantom-error dump kept happening even when LSP was giving us a clean
authoritative signal.
This change short-circuits the shell linter for the structurally-broken
extensions (`.ts`, `.tsx`, `.go`, `.rs`) when an LSP server is active
and claims the file via `LSPService.enabled_for(path)`. The LSP tier
runs as before and carries the real diagnostics in `lsp_diagnostics`.
Other shell linters (`py_compile`, `node --check`) keep running
unconditionally — they're fast, file-local, and correct.
Default behavior (LSP disabled, LSP misconfigured, remote backend, file
outside a workspace) is unchanged — the existing fallback paths trigger
when `_lsp_will_handle` returns False, so users who haven't opted into
LSP get the same shell-linter behavior they had before.
Drive-by: `.tsx` was missing from the `LINTERS` table entirely, so TS
React files got no post-edit syntax check at all. Added it for
symmetry; in practice it now hits the LSP-skip path.
Tests:
- `tests/agent/lsp/test_shell_linter_lsp_skip.py` — 14 tests covering:
* skip happens for each redundant extension when LSP claims the file
(asserted by patching `_exec` to raise on any shell-linter call)
* shell linter still runs when LSP is inactive (regression guard)
* `.py` / `.js` continue to run unconditionally even with LSP active
* `_lsp_will_handle` is exception-safe: returns False on None
service, remote backend, or `enabled_for` raising
* `.tsx` is in both `LINTERS` and `_SHELL_LINTER_LSP_REDUNDANT`
- All pre-existing tests in `tests/agent/lsp/` and
`tests/tools/test_file_operations*.py` still pass (233/233).
* fix(lint): address Copilot review on #29054
Two fixes from copilot-pull-request-reviewer on PR #29054:
1. `.tsx` regression with LSP disabled
(https://github.com/NousResearch/hermes-agent/pull/29054#discussion_r3271017282)
The first revision added `.tsx` to the `LINTERS` table so that
TypeScript React files would hit the LSP skip path. Side effect:
when LSP is *disabled* (the default), `.tsx` edits would suddenly
run `npx tsc --noEmit FILE.tsx` and inherit the same phantom-error
dump this PR is supposed to fix. Pre-PR behavior was implicit
`skipped` (no `LINTERS` entry); restore that.
- Remove `.tsx` from `LINTERS`.
- Remove `.tsx` from `_SHELL_LINTER_LSP_REDUNDANT` (the skip path
is unreachable without a `LINTERS` entry — falls through to
`ext not in LINTERS` first).
- When LSP IS enabled, `.tsx` is still covered by the LSP tier
via `_maybe_lsp_diagnostics` (typescript-language-server's
`extensions` tuple includes `.tsx`), so the diagnostics still
surface — just on the `lsp_diagnostics` channel, not `lint`.
- Update test_shell_linter_lsp_skip.py to reflect this contract
(drop `.tsx` from the parametrize lists; add
`test_tsx_stays_out_of_linters_table_for_default_compatibility`
and `test_tsx_default_check_lint_returns_skipped`).
2. V4A patches dropped `WriteResult.lsp_diagnostics`
(https://github.com/NousResearch/hermes-agent/pull/29054#discussion_r3271017295)
`tools/patch_parser.py::apply_v4a_operations` calls
`file_ops.write_file()` per operation, then calls `_check_lint()`
directly afterwards — but never propagates `WriteResult.lsp_diagnostics`
to the `PatchResult`. The shell-linter skip introduced in this PR
makes the gap visible: a `.ts` / `.go` / `.rs` V4A patch with LSP
active would return `lint = {f: {skipped: True}}` and zero
diagnostics from any channel.
- `_apply_add` and `_apply_update` now return
`Tuple[bool, str, Optional[str]]` where the third element is
`WriteResult.lsp_diagnostics` (or `None` on failure / no diags).
- `_apply_delete` and `_apply_move` stay 2-tuples — they don't
produce diagnostics, no write goes through `write_file`.
- `apply_v4a_operations` accumulates per-file diagnostics blocks
and surfaces a combined block on `PatchResult.lsp_diagnostics`.
Each block already carries its `<diagnostics file="...">` header
from `LSPService.report_for_file`, so concatenation preserves
per-file attribution.
Tests added (`test_patch_parser.py::TestV4ALspDiagnosticsPropagation`):
- ADD op: `WriteResult.lsp_diagnostics` flows to `PatchResult`
- UPDATE op: same
- No diagnostics → `PatchResult.lsp_diagnostics is None` (not "")
- Multi-file patch: combined block contains every per-file block
Verification:
- Targeted test scope: 257/257 pass
(tests/agent/lsp/, tests/tools/test_file_operations*.py,
tests/tools/test_patch_parser.py)
- Wider sweep: 5400 pass; 11 failures all pre-existing on origin/main
(file_staleness / file_read_guards / file_state_registry — unrelated
macOS /var/folders tmp-path sensitivity issues, confirmed by
re-running on a clean origin/main checkout)
* docs(test): align shell-linter LSP skip docstring with .tsx behavior
Copilot review feedback (review #4324947616, comment #3271049036):
the test module docstring still listed .tsx alongside .ts/.go/.rs in
the skip contract, but .tsx is now intentionally NOT in LINTERS or
_SHELL_LINTER_LSP_REDUNDANT. Updated the bullet list to drop .tsx from
the skip contract and added a paragraph documenting why .tsx is left
out (preserves pre-PR implicit-skip behavior for LSP-disabled users;
LSP coverage still happens via _maybe_lsp_diagnostics).
* test(lsp): drop unused tmp_path from _make_fops helper
Copilot review #3271069484: the helper accepted tmp_path but never
used it. Callers still need tmp_path themselves for the file they're
asserting against, so we just drop the helper's parameter.
Copilot caught an important runtime parity gap on PR #27489: the fix
imported the npm `wrap-ansi` package directly, but Ink's `<Text
wrap="wrap">` uses a runtime-selecting shim
(`ui-tui/packages/hermes-ink/src/ink/wrapAnsi.ts`) that prefers
`Bun.wrapAnsi` when running under Bun and falls back to the npm package
elsewhere. So under Bun, Ink would render via `Bun.wrapAnsi` while
`cursorLayout` would compute breaks via the npm package — any
disagreement reintroduces the exact cursor-drift symptom the PR is
meant to eliminate.
Fix:
- Export `wrapAnsi` from `@hermes/ink` (`packages/hermes-ink/src/entry-exports.ts`
and `packages/hermes-ink/index.d.ts`) so the shim is the public surface.
- Switch `ui-tui/src/lib/inputMetrics.ts` from `import wrapAnsi from
'wrap-ansi'` to `import { wrapAnsi } from '@hermes/ink'`. Both
renderer (Ink) and cursor layout now traverse the same shim, so
they share the runtime-selected implementation by construction.
- Same swap in `textInputWrap.test.ts` and `cursorDriftRegression.test.ts`
— tests now assert parity through the shim, which means under Bun
they actually exercise Bun's implementation instead of asserting a
tautology against the npm package.
- Drop the direct `"wrap-ansi": "^9.0.0"` from `ui-tui/package.json`.
`@hermes/ink` (which IS a declared dep) pulls wrap-ansi in
transitively — that's not a phantom dep because the import path
goes through `@hermes/ink`'s public exports, not through a
hoisting accident.
Verified: 791/791 vitest tests pass. `@hermes/ink` rebuilt
(`dist/entry-exports.js` includes `wrapAnsi` export). TUI bundle
rebuilt clean.
Three small follow-ups from the Copilot review on #27489:
1. Declare `wrap-ansi` as a direct dependency of `ui-tui`. It was a
phantom dep that resolved via npm hoisting from `@hermes/ink`'s
transitive graph — fine on hoisted installs, but breaks under pnpm
or `npm install --no-install-strategy=hoisted` style isolated
installs. Now listed as `"wrap-ansi": "^9.0.0"` matching the
@hermes/ink version. Lockfile regenerated.
2. Implement the defensive resync the comment promised. Previously the
comment claimed the loop would "fall back to advancing by one to
stay in lockstep" on wrap-ansi desync, but the code unconditionally
advanced `originalIdx` with no actual check — so any future
wrap-ansi option change or styled-input caller could silently slide
`originalIdx` past the end of `value` and emit garbage line ranges.
Now actually compares `value[originalIdx] === ch`, re-syncs via
`indexOf` on mismatch, and bails out (returning whatever was built
so far) if the desync is unrecoverable. Production paths still hit
the equality fast-path on every char.
3. Drop the `visualLines` wrapper. It was a one-line indirection over
`visualLinesFromWrappedOutput`. Renamed the implementation to
`visualLines` and removed the wrapper — same name, no extra layer.
No behavior change beyond the defensive realign; all 791 vitest tests
still pass.
The composer's `cursorLayout` (in `ui-tui/src/lib/inputMetrics.ts`) used a
hand-rolled word-wrap algorithm to decide where `useDeclaredCursor`
should park the hardware cursor. But Ink's `<Text wrap="wrap">` renders
the same text via `wrap-ansi`. The two algorithms disagreed on common
real-world inputs — `"branch investigate"` at cols=20, `"hello world"`
at cols=8, exact-fill strings like `"abcdefgh"` at cols=8 — so the
hardware cursor parked several cells past where Ink actually rendered
the last character. Users saw a multi-cell blank gap between their
last-typed letter and the cursor block, especially on narrow terminals
(the Cursor IDE built-in terminal was the worst offender).
Three previous PRs (#26717, #25860, #22197) chased fast-echo
displayCursor/cursorDeclaration drift and in-band-vs-native cursor
heuristics. None of them touched the underlying wrap-algorithm
mismatch, which is why the bug kept resurfacing.
Fix: source cursorLayout's line breaks from wrap-ansi directly. Walk
its emitted string char-by-char, tracking original-string offsets, push
a VisualLine at each '\n'. Also drop the buggy `column >= w` overflow
rule in cursorLayout — that's what pushed exact-fill text onto a
phantom next row.
canFastBackspaceShape now detects the wrap boundary in BOTH coordinate
conventions (column === 0 OR column >= columns), since exact-fill now
reports as (0, columns) instead of the previous (1, 0). The physical
state is identical — the terminal auto-wraps at column N either way —
but the layout function reports the position more honestly.
Tests:
- ui-tui/src/__tests__/textInputWrap.test.ts: 3 tests that pinned the
BUGGY behavior were updated to assert wrap-ansi parity (the real
invariant). Added a typing-prefix invariant: cursorLayout must agree
with wrap-ansi at every character of a long input.
- ui-tui/src/__tests__/cursorDriftRegression.test.ts: new file. Walks
the user-reported bug message char-by-char at 7 widths and asserts
agreement with wrap-ansi at every prefix.
Verification:
- 791/791 vitest tests pass.

cursor lands exactly 1 cell past the last typed char in every case
the bug previously drifted.
Consume multi-byte non-CSI ESC sequences during ANSI sanitization and handle UnicodeDecodeError for `hermes send --file` so review findings are resolved without regressions.
Strip incomplete CSI prefixes before rendering, remove carriage returns from sanitized output, and add regression tests to prevent escape-sequence recomposition across message boundaries.
Avoid Terminal.app paint corruption by disabling fast-echo in that terminal, sanitizing non-SGR control sequences before ANSI rendering, and defaulting Apple Terminal back to the safer 256-color path unless truecolor is explicitly requested.
* fix(tui): keep Ink displayCursor in sync with fast-echo writes so cursor stops drifting
TextInput's fast-echo bypass writes characters directly to stdout to
avoid waiting on a React re-render for each keystroke. The hardware
cursor advances by text.length cells, but Ink's cached `displayCursor`
(the basis for the next frame's relative cursor-move preamble in
log-update) stayed unchanged. When ANY unrelated component re-rendered
between the fast-echo write and the deferred composer setCur/setParent
flush — status bar timer, streaming reasoning, etc. — the next frame's
preamble emitted a relative cursor move from a stale parked position
and the hardware cursor parked N cells offset from the actual caret.
Visible symptom: extra whitespace between the just-typed character and
the cursor block, intermittent, worse on long sessions during streaming.
Alt-screen was immune because frames begin with absolute CSI H.
This adds a small API in @hermes/ink:
- `Ink.noteExternalCursorAdvance(dx, dy?)` — bumps displayCursor if
set, otherwise seeds from frontFrame.cursor so the next preamble's
relative move correctly cancels the external advance. No-op on
alt-screen.
- `CursorAdvanceContext` + `useCursorAdvance()` hook to expose it.
TextInput then calls `noteCursorAdvance(text.length)` after the
fast-echo `stdout.write(text)` append, and `noteCursorAdvance(-1)`
after the fast-backspace `\b \b` sequence.
Tests: 4 new vitest cases pin the API contract (bumps when set, seeds
from frontFrame.cursor when null, alt-screen no-op, zero-delta no-op).
All 751 ui-tui tests pass; tests/test_tui_gateway_server.py (177) pass.
* fix(tui): also advance cursorDeclaration so fast-echo survives deferred React state
Copilot review on PR #26717 flagged a gap in the original fix:
TextInput's fast-echo path defers the React `cur` state update by
16ms (perf optimization that batches re-renders during heavy typing).
Inside that window, `useDeclaredCursor` still publishes a target
computed from the PRE-keystroke `cur` — `cursorLayout(display, cur,
columns)`. Advancing only `displayCursor` would let any unrelated
re-render in that 16ms window run onRender's cursor-park branch with
the stale declaration and visually undo the fast-echo's advance.
The fix is symmetric: `noteExternalCursorAdvance` now bumps BOTH
`displayCursor` (the log-update relative-move basis) AND, if non-null,
`cursorDeclaration.relativeX/Y` (the target the cursor parks at after
every frame). When React finally flushes `setCur`, `useDeclaredCursor`
publishes a fresh declaration that supersedes our bumped one — exactly
what we want.
Adds two new vitest cases covering both halves:
- active declaration advances in lock-step with displayCursor
- null declaration stays null (no spurious bump)
All 753 ui-tui tests pass; tests/test_tui_gateway_server.py (177) pass.

* fix(tui): make fast-echo survive TextInput rerenders + alt-screen (Copilot round 2)
Round 2 of PR #26717 review. Three real holes Copilot flagged after the
initial cursorDeclaration bump:
1. alt-screen early-return skipped BOTH halves of the notifier. But the
default TUI wraps the composer in <AlternateScreen> — that IS the
production path. CSI H resets log-update's relative-move basis, but
the alt-screen park branch uses absolute CUP =
`rect.x + decl.relativeX`, so a stale declaration there still parks
the cursor at the pre-keystroke caret. Fix: skip ONLY the
displayCursor half on alt-screen; still bump cursorDeclaration.
2. TextInput's own rerender could clobber the Ink-level bump. The fast-
echo path defers setCur by 16ms; if a parent state change rerenders
TextInput in that window, the layout effect inside useDeclaredCursor
reads the stale React `cur` state and re-publishes a declaration at
the OLD column. Fix:
`cursorLayout(display, curRef.current, columns)` — read the always-
up-to-date ref, not the deferred state. useMemo dropped (compute is
cheap, single-line wrap-text in the common case).
3. Tests bypassed the production wiring. Added two structural tests:
- `still advances cursorDeclaration on alt-screen` in the Ink-level
suite, asserting displayCursor stays put but the declaration
advances by the delta.
- `textInputCursorSourceOfTruth.test.ts` pins three structural
invariants: layout reads curRef.current, never the bare `cur`
state, and the fast-echo stdout.write calls remain paired with
noteCursorAdvance(±N). Source-grep invariants > flaky Ink mount
tests for this kind of regression.

* fix(tui): reject fast-backspace at soft-wrap boundary (Copilot round 3)
PR #26717 round 3. Copilot caught two real things:
1. `\b \b` cannot move the terminal cursor onto the previous visual
row across a soft-wrap boundary. When the caret sits at visual
column 0 of a wrapped row (e.g. value 'hello ' at width 6 →
cursorLayout produces (line 1, col 0)), backspace would leave the
physical cursor in place while the logical caret moves up to the
end of the previous visual line. `noteCursorAdvance(-1)` would then
feed Ink a wrong delta. Fix: `canFastBackspaceShape` now takes the
composer width and rejects when `cursorLayout(value, cursor, columns).column === 0`.
The fast path falls through to the normal Ink render, which
correctly lays out the new caret position. The PR-description
inconsistency about alt-screen is fixed in a separate gh pr edit.
Adds 4 new tests in textInputFastEcho.test.ts pinning the rejection at
exact-multiple wrap boundaries plus a positive control inside a
wrapped line and a back-compat case where `columns` is omitted.

PRRT_kwDOPRF1G86ChxE5 (textInput.tsx:933 wrap-boundary regression)
* fix(tui): polish doc + tests after Copilot round 4
Three polish points Copilot raised:
1. canFastBackspaceShape doc comment overstated the legacy contract —
said it conservatively rejects potential wrap boundaries when
columns is omitted, but the implementation actually skips the
wrap-boundary check entirely. Reworded to make the legacy behavior
explicit and warn callers not to rely on protection they don't get.
2. ink-cursor-advance.test.ts rationale comment for the
'advances cursorDeclaration in lock-step' case still referenced
the pre-fix `cursorLayout(display, cur, columns)` expression. Now
accurately describes the current source of truth — `curRef.current`
in textInput.tsx — and explains the window the bump is bridging.
3. Removed the three `__get*ForTest` accessors from Ink. The test
file already cast the instance to inspect private state in the
couple of tests that needed declaration mutation; the rest now use
a small `peek(ink)` helper that does the same cast for reads. No
test-only API surface ships in production.
761/761 ui-tui tests pass. type-check clean. lint introduces zero new
errors on touched files. 177/177 tests/test_tui_gateway_server.py pass.

* fix(tui): tighten doc + add dy test coverage (Copilot round 5)
Two polish points from round 5:
1. canFastBackspaceShape doc had two paragraphs that conflicted —
the main 'Additionally rejects when the physical cursor sits at
visual column 0' was stated unconditionally, then the columns-param
paragraph qualified that it only happens when columns is passed.
Reworked into clear 'When supplied / When omitted' branches with a
concrete example value ('hello ' returns true without columns even
though it would be unsafe at width 6). No more inconsistency.
2. Added a test asserting cursorDeclaration.relativeY advances when dy
is non-zero. Existing tests exercised dy on displayCursor only.
Newlines in fast-echoed text don't currently hit the bypass
(canFastAppendShape rejects '\n'), but dy is part of the public
notifier contract and must propagate symmetrically with dx so
future callers get a fully-implemented contract.
762/762 ui-tui tests pass (+1). type-check / lint / build clean.
Closes review threads:
PRRT_kwDOPRF1G86Ch6Sz (doc inconsistency)
PRRT_kwDOPRF1G86Ch6TE (missing dy coverage on declaration)
* fix(tui): doc polish (Copilot round 6)
Four small but valid points:
1. textInputCursorSourceOfTruth.test.ts used bare 'fs'/'path'/'url'
imports; the rest of ui-tui consistently uses the 'node:' prefix
(see src/__tests__/useSessionLifecycle.test.ts, src/lib/editor.test.ts).
Switched to node:fs / node:path / node:url to match convention.
2. CursorAdvanceContext.ts type-level doc described only displayCursor.
The notifier intentionally also mutates the active cursorDeclaration
and that's the only part that matters on alt-screen. Reworked the
doc into a two-part 'updates both' summary with the alt-screen
asymmetry called out explicitly.
3. use-cursor-advance.ts hook doc had the same problem. Same fix —
document both pieces of state, both screen modes.
4. App.tsx onCursorAdvance prop comment was incomplete. Same fix —
describe both state updates and the screen-mode asymmetry.
No behavior change. 762/762 ui-tui tests pass. type-check / lint /

When an approval / clarify / confirm overlay was active, the global input
handler in useInputHandlers returned for every key that wasn't Ctrl+C, which
silently disabled transcript scrolling. On long threads the context the
prompt was asking about often lived above the visible viewport, and being
unable to scroll while answering felt like the prompt had locked the UI.
ApprovalPrompt also had no Esc handler at all, so the one obvious 'abort'
key did nothing during a permission prompt and the user had to memorize
Ctrl+C or hunt for the deny number.
Fixes:
- Extract shouldFallThroughForScroll(key) (pure, exported) covering wheel
scrolls, PageUp/PageDown, and Shift+ArrowUp/Down. When a prompt overlay
is up and the pressed key is a scroll input, skip the early return so it
reaches the existing wheel/PageUp/Shift+arrow handlers below. Plain
arrows still drive in-prompt selection — they don't fall through.
- ApprovalPrompt now maps Esc to onChoice('deny'), parity with the global
Ctrl+C cancellation path that already invokes cancelOverlayFromCtrlC()
for approvals. The bottom-of-prompt hint now advertises 'Esc/Ctrl+C deny'.
- Extract approvalAction(ch, key, sel) — pure key-dispatch helper for the
approval prompt, exported so the regression matrix (Esc, numbers, Enter,
arrows, edge clamping, precedence) is testable without mounting Ink.
Tests:
- useInputHandlers.test.ts: 6 cases covering shouldFallThroughForScroll
positives (wheel/PageUp/PageDown/Shift+arrows) and negatives (plain
arrows, bare shift, no scroll key).
- approvalAction.test.ts: 8 cases covering Esc→deny, numeric mapping,
Enter, ↑↓ within bounds, edge clamping, Esc-beats-others precedence,
unrelated keystrokes.
Accept delegation timeout/error statuses in the TUI subagent model, normalize unknown status strings defensively, and harden /agents overlay rendering/sorting so unknown statuses cannot crash glyph/color lookup. Add regression tests for live event normalization and disk snapshot replay.
Avoid shifting the terminal's last visible row in the alt-screen DECSTBM fast path, which can leave transient scroll bleed/discoloration artifacts around the status lane until a repaint. Add regression tests to preserve the fast path when safe and skip it when the hint touches the bottom row.
* fix(tui): restrict fast-echo bypass to ASCII so Vietnamese/CJK/IME input renders correctly
The composer's fast-echo path (canFastAppend / canFastBackspace) writes
characters straight to stdout to skip an Ink re-render on the hot
typing path. The previous guard only checked
'stringWidth(text) === text.length', which lets a lot of non-ASCII
through:
- Vietnamese precomposed letters (ề, ắ, ờ, ự, ...) report width 1 and
length 1, but a Vietnamese Telex / IME stack produces them across
multiple keystrokes; the intermediate composition state must be
drawn by Ink so the rendered cell, the stored value, and the
cursor column stay in lockstep when the final commit replaces the
preview.
- NFD combining marks (U+0300..U+036F) are zero-width but length 1,
so even a passing equality lets them slip and silently desync the
cell column.
- CJK/East-Asian wide and emoji rejected only because their length
differs, but the boundary was shape-shaped, not intent-shaped.
User-visible bug from the original report:
Example: eê noiói nge neène
-> the bypass committed the IME preview char before the diacritic
replaced it, leaving doubled letters on screen.
Fix: gate fast-echo on pure printable ASCII (0x20-0x7e). The
performance-critical English typing path is unchanged; everything else
goes through the normal Ink render path so layout stays accurate.
Also extracts the shape preconditions as pure exported helpers
(canFastAppendShape / canFastBackspaceShape) so the regression matrix
is testable without spinning up a TextInput.
Tests: ui-tui/src/__tests__/textInputFastEcho.test.ts adds 20 cases
covering ASCII still works, Vietnamese precomposed + NFD, CJK, emoji,
NBSP / Latin-1, ANSI / control bytes, multi-line, and end-of-line
preconditions. Verified RED on the previous guard (11 of 20 fail) and
GREEN on the new guard.
Refs: #5221, #7443, #17602, #17603 (similar wide-char rendering bugs).
* docs(tui): clarify Vietnamese char terminology in regression comment
Address Copilot review: 'single byte width' implied UTF-8 byte semantics,
but the relevant property is JS code units (`text.length === 1`) and
display width (`stringWidth === 1`). Reworded to match.
Two long-standing prompt_toolkit bugs in the base hermes CLI:
1. Resize duplication. Column-shrink resize used to push 40+ rows of
duplicate chrome (status bar, input rules) into terminal scrollback
every resize. Same wall as pt issues #29 (open since 2014), #1675,
#1933 — aider/xonsh/ipython all use alt-screen to dodge it.
Root cause (verified by reading prompt_toolkit/renderer.py):
_output_screen_diff (renderer.py L232-242) deliberately moves the
cursor to the bottom of the canvas after every paint 'to make sure
the terminal scrolls up'. In non-fullscreen mode this scrolls chrome
content into terminal scrollback on every render — not just on
resize.
Fix: monkey-patch prompt_toolkit.renderer._output_screen_diff to
bypass the reserve-vertical-space cursor move. When pt's logic checks
'if current_height > previous_screen.height', we inflate the previous
screen height so the branch falls through. ~30-line wrapper, no fork
of pt, no alt-screen, no DECSTBM scroll region.
Verified empirically in real Terminal.app: 10 resizes (mixed
shrinks/widens 1300→500→1400) during streaming produced ZERO
scrollback delta, full agent response preserved, status bar pinned
at bottom, no visible duplicates. pt is pinned to ==3.0.52 so the
private-function patch is safe; future pt bumps will need to
re-verify the signature matches.
2. Light-mode terminal visibility. Hardcoded skin colors (#FFF8DC
cornsilk, #FFD700 gold, #B8860B dark goldenrod) are tuned for dark
Terminal.app — invisible on light/cream backgrounds.
Port ui-tui/src/theme.ts detectLightMode() to Python so the base CLI
adapts. Detection priority: HERMES_LIGHT/HERMES_TUI_LIGHT env →
HERMES_TUI_THEME=light|dark → HERMES_TUI_BACKGROUND=#RRGGBB →
COLORFGBG env (xterm/Konsole/urxvt) → OSC 11 query
(\x1b]11;?\x1b\\) with 100ms timeout → default dark. OSC 11 is
tty-gated so gateway/cron/batch/subagent code paths don't pay the
timeout cost.
When light mode is detected, dark-mode colors auto-remap to readable
equivalents (#FFF8DC → #1A1A1A, #FFD700 → #9A6B00, etc). Hooked at
three points:
- _hex_to_ansi() — auto-remaps any color emitted via the ANSI helper
- _build_tui_style_dict() — rewrites pt style strings (chrome bg/fg)
- SkinConfig.get_color() — wrapped at module load so Rich Panel
borders/body text get the remap too
Status-bar foreground colors (#C0C0C0, #888888, etc.) are explicitly
skipped because they're paired with a dark navy bg — remapping them
would make them invisible in dark mode.
3. Other visibility fixes: [thinking] reasoning preview now uses ANSI
dim+italic (\x1b[2;3m) instead of #B8860B so it inherits terminal
default fg color. Input/prompt area defaults to terminal default fg
(was #FFF8DC cornsilk → invisible on cream).

* tui: make URLs clickable + hover-highlight in any terminal
Problem
-------
URLs printed by `hermes --tui` were not clickable in basic macOS Terminal.app.
Cmd+click did nothing, the cursor didn't change shape — like nothing was
detected — even though arrow buttons and other Box onClick handlers worked
fine.
Root cause
----------
Two layers of dead plumbing:
1. `<Link>` only emitted the underlying `<ink-link>` (which carries the
hyperlink metadata into the screen buffer) when `supportsHyperlinks()`
said yes. On Apple_Terminal that's false, so the per-cell hyperlink
field stayed empty, so `Ink.getHyperlinkAt()` had nothing to return on
click. The visible underline was just decorative.
2. `Ink.openHyperlink()` calls `this.onHyperlinkClick?.(url)`, but
`onHyperlinkClick` was never assigned anywhere in the codebase. The
click pipeline (`App.tsx → onOpenHyperlink → Ink.openHyperlink`) ran
but bailed silently on the optional chain.
Bonus discovery: even when wired up, there was no hover affordance —
terminal apps can't change the system mouse cursor, so users had no
visual signal that a cell was clickable. Arrow buttons in the chrome
worked because they had explicit `<Box onClick>` styling; inline link
URLs didn't.
Fix
---
- `Link.tsx`: always emit `<ink-link>` regardless of terminal capability.
The renderer's `wrapWithOsc8Link` already gates the actual OSC 8 escape
on `supportsHyperlinks()` further down — so terminals that don't
understand OSC 8 still don't see the escape, but the screen-buffer
metadata (which the click dispatcher reads) is now populated everywhere.
- `ink.tsx + root.ts`: add `onHyperlinkClick?: (url: string) => void` to
`Options` / `RenderOptions`, wire it to the existing `Ink.onHyperlinkClick`
field in the constructor.
- `src/lib/openExternalUrl.ts`: small platform-aware opener using
`child_process.spawn` with arg-array (no shell) — http(s) only, rejects
`file:`, `javascript:`, `data:`, etc., so a hostile model can't trigger
arbitrary local handlers via `<Link url="file:///...">`. Detached + stdio
ignore so closing the TUI doesn't kill the browser and Chrome stderr
doesn't leak into the alt screen.
- `entry.tsx`: pass `onHyperlinkClick: openExternalUrl` to `ink.render`.
- `hyperlinkHover.ts` + Ink hover wiring: track the URL under the pointer
in `Ink.hoveredHyperlink`, update it from `dispatchHover`, and inverse-
highlight every cell of the matching link in the render-pass overlay
(same pattern as `applySearchHighlight`). This is the cursor-hover
affordance for clickable links — terminals don't expose cursor shape,
so we light up the link itself.
- `types/hermes-ink.d.ts`: add `onHyperlinkClick` to the `RenderOptions`
shim so consumers (`entry.tsx`) type-check against the new option.
Tests
-----
- `src/lib/openExternalUrl.test.ts` (15 cases): http(s) accepted; file/js/
data/mailto/ftp/ssh rejected; macOS open(1), Windows cmd.exe start with
empty title slot, Linux xdg-open dispatch; shell-metacharacter URLs
pass through unmolested as a single argv element; synchronous spawn
failure returns false.
Verified empirically in Apple Terminal 455.1 (macOS 15.7.3): clicking a
URL opens in default browser, hovering inverts the link cells, and
moving away clears the highlight. Full TUI suite: 713 passing, 0
type errors.
Reverts
-------
The earlier attempt that version-gated Apple_Terminal in
`supports-hyperlinks.ts` was based on a wrong assumption — Terminal.app
silently strips OSC 8 sequences but does not render them as clickable
hyperlinks. Reverted to the original allowlist.
* tui: address Copilot review — explorer.exe on win32 + comment fixes
- openExternalUrl: switch win32 from `cmd.exe /c start` to `explorer.exe`.
cmd.exe's `start` builtin reparses the URL through cmd's tokenizer, so
`&`, `|`, `^`, `<`, `>` either split the command or get reinterpreted —
breaking both the protocol-allowlist safety story AND plain http(s) URLs
with `&` in query strings. `explorer.exe <url>` invokes the registered
protocol handler directly with no shell.
- openExternalUrl.test.ts: rename the win32 test to reflect the new
contract and add two regression tests — one with `&|^<>` metachars,
one with the common analytics-URL `&` query-param pattern — both pinned
to single-argv-element delivery via explorer.exe.
- Link.tsx: fix misleading comment. OSC 8 escapes are emitted
unconditionally by the renderer (`wrapWithOsc8Link` in
render-node-to-output.ts, `oscLink` in log-update.ts). Non-supporting
terminals silently strip the sequence, which is why hover/click
affordance has to come from the in-process overlay rather than the
terminal's own link rendering.
Verified: 715/715 tests pass, type-check + build clean.
* tui: address Copilot review #2 — async spawn errors + hover scope + docs
1. openExternalUrl: attach a no-op `'error'` listener on the spawned
child BEFORE unref(). spawn() returns a ChildProcess synchronously
even when the binary is missing (ENOENT on xdg-open / explorer.exe),
unreachable, or otherwise unusable; the failure surfaces later as
an 'error' event. An unhandled 'error' on an EventEmitter crashes
Node, which would tear down the whole TUI. The listener is a
deliberate no-op — we already returned `true` synchronously and the
user just doesn't see the browser pop.
2. openExternalUrl.test.ts: add a regression test using a real
EventEmitter to simulate the async-error path. Pins both the
listener-attached contract and the "doesn't throw on emit" behavior.
Was 17/17, now 18/18.
3. ink.tsx dispatchHover: bypass `getHyperlinkAt()` and read
`cellAt(...).hyperlink` directly. `getHyperlinkAt` falls back to
`findPlainTextUrlAt` for cells without an OSC 8 hyperlink, but the
render-pass overlay (`applyHyperlinkHoverHighlight`) only matches on
`cell.hyperlink === hoveredUrl` — so plain-text URLs would burn
re-renders without ever producing the highlight. Hover is now a
strictly 1:1 fit for what the overlay can paint. Plain-text URLs
still get the click action via the existing dispatch path.
4. root.ts + ink.tsx doc comments: replace the misleading "typically
`open` / `xdg-open` / `start` shell" wording with the actual safe
recipe — argv-array spawn into `open` / `xdg-open` / `explorer.exe`,
with an explicit warning that `cmd.exe /c start` reparses the URL
through cmd's tokenizer and is unsafe + breaks `&`-query URLs.
Verified: 716/716 tests pass, type-check + build clean.
* tui: address Copilot review #3 — hover damage, alt-screen cleanup, opener allowlist
1. ink.tsx onRender: stop folding steady-state hover into hlActive.
hlActive forces a full-screen damage diff so previous-frame inverted
cells get re-emitted when the highlight set changes. The transition
IS the trigger — enter / leave / change-to-other-link. While the
pointer just sits on a link the painted cells don't change and the
per-cell diff handles the no-op. Folding the steady state in would
burn a full-screen diff on every frame. Added a
lastRenderedHoveredHyperlink tracker and gate the hlActive bump on
`hovered !== lastRendered`.
2. ink.tsx setAltScreenActive: clear hoveredHyperlink (and the tracker)
when toggling alt-screen state. Hover dispatch is alt-screen-gated,
so once we leave there's no path to clear it. Without this, remounting
<AlternateScreen> would paint a phantom hover from the previous
session until the next mouse-move arrived.
3. openExternalUrl.ts openCommand: allowlist linux + the BSD family for
xdg-open and return null for everything else (aix, sunos, cygwin,
haiku, etc.). Previously the default-fallback always returned
xdg-open, which made the caller's `if (!command) return false` dead
and yielded a misleading `true` on platforms that probably don't
have xdg-open. New tests cover the null path AND the
openExternalUrl-returns-false-without-spawning behavior.
Verified: 718/718 tests pass, type-check + build clean.
* tui: address Copilot review #4 — doc comment accuracy
1. openExternalUrl return-value doc: now lists all three false paths
(URL rejected / no opener for platform / synchronous spawn throw)
plus a note that async 'error' events still return true because the
spawn was attempted.
2. ink.tsx onHyperlinkClick field doc: clarifies the callback receives
either an OSC 8 hyperlink OR a plain-text URL detected by
findPlainTextUrlAt — App.tsx routes both into the same callback.
3. hyperlinkHover applyHyperlinkHoverHighlight doc: drops the misleading
'caller forces full-frame damage' promise. Caller decides; for hover
the current caller only forces full damage on transitions.
No behavior change. 718/718 tests pass.
* tui: address Copilot review #5 — lint fixes
1. ink.tsx: reorder `./hyperlinkHover.js` import before `./screen.js` to
satisfy perfectionist/sort-imports.
2. Link.tsx: drop unused `fallback` parameter destructuring + the
trailing `void (null as ...)` dead-statement (would trip
no-unused-expressions). Kept `fallback?: ReactNode` on the Props
interface as a documented compat shim so existing call sites still
compile, with a comment explaining why it's no longer wired up.
3. openExternalUrl.test.ts: replace `typeof import('node:child_process').spawn`
inline annotations (forbidden by @typescript-eslint/consistent-type-imports)
with a `SpawnLike` type alias backed by a real `import type { spawn as SpawnFn }`.
No behavior change. 718/718 tests pass, type-check clean, lint clean on
all modified files.

Move list and quote indentation into layout padding so trim-aware wrapping does not erase nested markdown structure.
* fix(tui): trim only soft wrap spaces
Change trim-aware wrapping to remove whitespace only at soft-wrap boundaries so original leading inline spaces stay verbatim.
* fix(tui): preserve extra boundary whitespace
Trim only one soft-wrap boundary whitespace character so wrap-trim avoids leading continuations without collapsing intentional spacing.
* fix(tui): align styled wrap-trim mapping
Update styled text remapping to skip the single whitespace removed at soft-wrap boundaries without dropping preserved indentation.
* fix(tui): clean wrap trim test helpers
Clarify boundary-trim wording and strip OSC escapes from markdown render test output.
* fix(tui): strip osc before ansi in markdown tests
Remove OSC escapes from raw render output before SGR/CSI cleanup so markdown render assertions stay plain text.
* feat(tui): support attaching to an existing gateway
Allow the TUI gateway client to connect via HERMES_TUI_GATEWAY_URL while preserving spawned gateway fallback, and mirror event frames to sidecar feeds so dashboard tool activity remains visible.
* review(copilot): redact attach URLs and gate stale transport exits
Strip query strings (and any user info) from gateway / sidecar URLs before logging or surfacing them in `gateway.start_timeout`, so attach tokens never leak into the TUI log tail or activity feed. Also gate the spawned-proc and websocket close handlers on transport identity so a stale child or socket cannot clear a freshly-started ready timer or reject newly-issued pending requests during reconnect.
* review(copilot): tighten transport restart and shutdown lifecycle
Reject any in-flight RPCs in resetStartupState so callers do not hang on promises issued to the previous transport when start() swaps a child or socket. Have kill() explicitly reject pending so attach-mode promises drain after an intentional shutdown, and reattach when HERMES_TUI_GATEWAY_URL rotates between requests instead of silently keeping the old session. Fold the spawned child error path through handleTransportExit so a failed spawn clears the startup timer and emits a single exit event. Also null the websocket reference before calling close so the identity guard correctly tags stale close events on real WebSocket timing. Locks the new behaviors in with regression tests for kill, URL rotation, and stale-pending cleanup.
* review(copilot): swallow stray ws connect rejection and isolate test env
Attach a no-op catch handler on the websocket connect promise so an unobserved connect-error / early-close rejection cannot surface as an unhandled promise rejection in Node when no request is currently racing the open. Snapshot HERMES_TUI_GATEWAY_URL / HERMES_TUI_SIDECAR_URL in beforeEach and restore them in afterEach so vitest runs that set those env vars beforehand do not get permanently cleared.

* review(copilot): hoist wire decoder and harden redact fallback
Reuse a single module-level TextDecoder for binary websocket frames so high-frequency attach-mode traffic does not allocate one per message. Strengthen the redactUrl fallback so embedded user:pass@ credentials are also masked when the WHATWG URL parser rejects the input, and pin the new behavior with a regression test that drives a malformed bearer URL through the gateway-stderr publish path.
* Potential fix for pull request finding

* review(copilot): force redact fallback path with deterministic fixture
Replace the "%zz" user-info fixture, which WHATWG URL actually accepts in recent Node and silently routed the test back through the structured-URL branch, with a port-99999 fixture that the parser rejects across Node versions. Add a pre-flight `expect(() => new URL(fixture)).toThrow()` assertion so a future URL-parser change can never silently bypass `redactUrl()`'s fallback again.
* review(copilot): sanitize websocket constructor failures
Avoid logging raw WebSocket constructor error messages because some implementations include the full input URL, including token-bearing query strings. Log the redacted gateway or sidecar URL with the error class instead, and add regression coverage for constructor-throw paths on both attach and sidecar sockets.
* review(self): restart transport on attach-mode transition
Route runtime HERMES_TUI_GATEWAY_URL changes through start() so switching from spawned-gateway mode to attach mode also tears down the previously spawned Python child instead of leaving it alive. Keep the existing fast-fail behavior for pending RPCs. Also make constructor-failure logging fully generic after the redacted URL, avoiding even implementation-specific error class text in the log tail.
* review(copilot): use websocket wording for attach close errors
When the attached websocket closes, reject pending RPCs with an explicit websocket-closed reason instead of the spawned-process oriented `gateway exited` wording. Add coverage to ensure close code 1011 surfaces as `gateway websocket closed (1011)`.

Multi-turn transcripts ran together visually because every user message
got the same vertical rhythm regardless of position. Adds a short ─── in
the border colour above every user message after the first, so each turn
reads as its own block. Height estimator gains a `withSeparator` flag so
virtual scrolling pre-allocates the extra two rows (rule + top margin)
and avoids a jump on first measurement.
While in the area: the busy-indicator duration was padded with
`padStart(7)`, leaving five visible spaces between `·` and the digits
(`⠋ · 2s`) — especially loud under the verb-less `unicode` style.
Drop the padding entirely (`⠋ · 2s`); the model label now shifts a few
columns as the duration grows, which is the right trade-off for the
minimal indicator styles. The verb-padding test stays; the
duration-padding test is removed alongside the function it covered.
* fix(tui): restore classic CLI voice push-to-talk parity
(cherry picked from commit 93b9ae301bb89f5b5e01b4b9f8ac91ffa74fbd9d)
* fix(tui): harden voice push-to-talk stop flow
Address review feedback from PR #16189 by stopping the active recorder before background transcription, documenting single-shot voice capture, and covering the TUI gateway flags with regression tests.
* fix(tui): preserve silent voice strike tracking
Keep single-shot voice recording's no-speech counter alive across starts so the TUI can still emit the three-strikes auto-disable event, and bind the auto-restart state at module scope for type checking.
* fix(tui): clean up voice stop failure path
Address follow-up review by naming the TUI flow as single-shot push-to-talk and cancelling the recorder when forced stop cannot produce a WAV.
* fix(tui): report busy voice capture starts
Return explicit start state from the voice wrapper so the TUI gateway does not report recording while forced-stop transcription is still cleaning up.
* fix(tui): handle busy voice record responses
Apply the gateway busy status immediately in the TUI and route forced-stop voice events to the session that sent the stop request.
* fix(tui): clear voice recording on null response
Treat a null voice.record RPC result as a failed optimistic start so the REC badge cannot stick after gateway-side errors.
* fix(tui): count silent manual voice stops
Preserve single-shot voice no-speech strikes through forced stop transcription so empty push-to-talk captures still trigger the three-strikes guard.

* fix(tui): steady transcript scrollbar
Keep the visible scrollbar tied to committed viewport position while virtual history can still prefetch against pending scroll targets, and preserve drag grab offset synchronously for native-feeling scrollbar drags.
* fix(tui): smooth precision wheel scroll
Replace the opt-scroll throttle with frame-sized coalescing so modifier wheel gestures stay line-precise without stepping.
* fix(tui): close slash parity gaps with CLI
Route unsupported /skills subcommands through slash.exec, support /new <name>
titles, and handle /redraw natively so TUI behavior matches classic CLI. Also
filter gateway-only commands out of the TUI catalog while keeping /status
discoverable.
* fix(tui): run remaining CLI parity paths natively
Forward chat launch flags into the TUI runtime and handle live-session status
and skill reloads in the gateway process so TUI state no longer depends on the
slash worker's stale CLI instance.
* fix(tui): block stale snapshot restores
Prevent snapshot restore from running through the isolated slash worker because
it mutates disk state without refreshing the live TUI agent.
* chore: uptick
* fix(tui): guard async session title updates
Handle failures from the fire-and-forget session.title RPC so title-setting errors do not surface as unhandled promise rejections while preserving session-scoped messaging.
Subscribe overlay components to computed theme/session selectors instead of the full UI store so unrelated UI state updates trigger fewer overlay renders.
* fix(tui): respect voice.record_key config instead of hardcoded Ctrl+B
Classic CLI loaded ``voice.record_key`` from config.yaml and bound the
prompt-toolkit handler dynamically (``cli.py`` paths). The new TUI hard-
coded ``Ctrl+B`` everywhere — ``isVoiceToggleKey`` (input handler),
``/voice status`` ("Record key: Ctrl+B"), and ``/voice on`` ("Ctrl+B to
start/stop recording"). A user who set ``voice.record_key: ctrl+o``
(or any other key) saw the documented config silently ignored — only
Ctrl+B worked, the displayed shortcut lied about it.
Wire the configured key end to end through the existing channels:
* **Backend** (``tui_gateway/server.py``): ``voice.toggle`` action=status
AND action=on/off responses now include ``record_key``, sourced from
``config.get('voice', {}).get('record_key', 'ctrl+b')``.
* **Backend types** (``ui-tui/src/gatewayTypes.ts``): ``ConfigFullResponse``
now exposes ``config.voice.record_key`` and ``VoiceToggleResponse``
carries ``record_key`` so the TUI can both bind and display it.
* **Frontend parser/formatter** (``ui-tui/src/lib/platform.ts``):
``parseVoiceRecordKey()`` accepts ``ctrl+b`` / ``alt+r`` / ``cmd+space``
and the common aliases (``option``, ``cmd``, ``win``, …); falls back to
the documented Ctrl+B for empty / multi-character / malformed input so
a typo never silently disables the shortcut. ``formatVoiceRecordKey()``
renders for status text. ``isVoiceToggleKey`` now takes a parsed
``ParsedVoiceRecordKey`` argument; the hardcoded ``ch === 'b'`` is
gone. Default arg keeps existing call sites back-compat.
* **Hydration** (``ui-tui/src/app/useConfigSync.ts``,
``useMainApp.ts``): startup ``config.get full`` already runs; extract
``cfg.voice.record_key`` from it, parse, push into a new
``voiceRecordKey`` state, and forward to the input handler ctx
(``InputHandlerContext.voice.recordKey``). Mtime-poll path also
re-applies the parsed key so a hand-edit of config.yaml takes effect
the next tick — matches existing behaviour for display options.
* **Input handler** (``ui-tui/src/app/useInputHandlers.ts``):
``isVoiceToggleKey(key, ch, voice.recordKey)`` so the configured
binding fires.
* **Slash command** (``ui-tui/src/app/slash/commands/session.ts``):
``/voice status`` and ``/voice on`` use ``formatVoiceRecordKey`` on
the response's ``record_key`` instead of the hardcoded label.
Tests:
* ``parseVoiceRecordKey`` covers ctrl/alt/cmd/super aliases, multi-char
rejection, and empty fallback.
* ``formatVoiceRecordKey`` covers the doc examples (``Ctrl+B``,
``Ctrl+O``, ``Alt+R``, ``Cmd+B``).
* ``isVoiceToggleKey`` regression: ``ctrl+o`` configured → only ``o``
matches, not ``b``; ``alt+r`` matches both alt-bit and meta-bit
encodings (terminal protocol parity); omitted-arg call still binds
Ctrl+B for back-compat.
Full TUI suite (555 tests) passes; ``tsc --noEmit`` clean.
Fixes#18994

* fix(tui): support named-key tokens in voice.record_key (space, enter, …)
Reviewer caught that the round-1 parser in #18994 rejected every
multi-character token, so a config value like ``ctrl+space`` (which the
CLI happily binds via prompt_toolkit's ``c-space`` rewrite in
``cli.py``) silently fell back to the documented Ctrl+B default —
re-introducing the same false-shortcut bug the PR was meant to fix,
just at a different surface.
Add explicit named-key support that mirrors what the CLI accepts:
* ``space`` (alias: ``spc``) → matches ``ch === ' '``
* ``enter`` (alias: ``return``, ``ret``) → matches ``key.return``
* ``tab`` → matches ``key.tab``
* ``escape`` (alias: ``esc``) → matches ``key.escape``
* ``backspace`` (alias: ``bs``) → matches ``key.backspace``
* ``delete`` (alias: ``del``) → matches ``key.delete``
``ParsedVoiceRecordKey`` gains an optional ``named`` field; ``ch``
holds either a single char (back-compat) or the canonical named token,
and the runtime matcher dispatches on ``named`` before checking the
modifier shape. Aliases collapse to one canonical name so
``ctrl+esc`` and ``ctrl+escape`` behave identically.
Unrecognised multi-character tokens (e.g. ``ctrl+spcae`` typo, or
unsupported keys like ``ctrl+f5``) still fall back to the Ctrl+B
default rather than silently disabling the binding — keeps the "typo
never silently kills the shortcut" guarantee.
Tests:
* ``parseVoiceRecordKey`` parametrised over every named token + each
alias variant.
* New ``isVoiceToggleKey`` cases for space (ch-based match), enter
(``key.return``), tab, escape, backspace, delete, including
modifier-mismatch negatives.
* ``formatVoiceRecordKey`` renders named keys in title case
(``Ctrl+Space``, ``Ctrl+Enter``).
* Existing fall-back-to-Ctrl+B contract preserved for empty input
AND unrecognised multi-char tokens.
Full TUI suite: 559/559 pass; ``tsc --noEmit`` clean.

* test(tui): assert voice.toggle returns configured record_key
Salvage the backend regression from #19339 — asserts ``voice.toggle``
action=on AND action=status responses carry the configured
``voice.record_key`` end-to-end through ``_load_cfg()``. Keeps the
CLI→TUI parity contract visible in the Python test suite alongside
the existing frontend parser/matcher/formatter coverage from #19028.
* fix(tui): address Copilot review on #19835 voice.record_key wiring
Five tightenings on the parser + matcher + hydration surface, all
caught by the Copilot review on the PR — each one turns a silent
false-fire or display/binding skew into a deterministic behaviour.
* **isVoiceToggleKey ctrl branch was too permissive for named keys.**
The doc-default macOS Cmd+B muscle-memory fallback
(``isActionMod(key)`` on top of ``key.ctrl``) fired for every
configured key, so bare Esc — which hermes-ink reports with
``key.meta`` on some macOS terminals — triggered ``ctrl+escape``,
and Alt+Space / Alt+Tab triggered ``ctrl+space`` / ``ctrl+tab``.
Gate the fallback to the literal ``ctrl+b`` binding so any custom
chord requires the real Ctrl bit.
* **Alt branch guarded against Ctrl/Cmd co-press.** Without this,
Ctrl+Alt+<letter> and Cmd+Alt+<letter> also fired ``alt+<letter>``.
* **Dropped the ``meta`` modifier variant and its alias.** In
hermes-ink ``key.meta`` is Alt on xterm-style terminals and Cmd on
legacy macOS ones, so a literal ``meta+b`` config displayed as
``Cmd+B`` while matching Alt+B — exactly the kind of false
shortcut the PR was meant to remove. ``cmd`` / ``command`` now
collapse onto ``super`` (kitty-style ``key.super``, with a macOS
``key.meta`` fallback) and render as ``Cmd+B``. Unknown modifier
tokens fall back to the documented Ctrl+B default rather than
silently coercing to Ctrl.
* **Slash-command display/binding skew.** ``/voice status`` and
``/voice on`` rendered from the fresh gateway ``record_key``
response, but ``useInputHandlers()`` still bound the old key
until the next 5s mtime poll. Thread ``setVoiceRecordKey``
through ``SlashHandlerContext.voice`` and push the parsed spec
into frontend state on every response so text and binding stay
consistent.
* **Test coverage for the two paths Copilot flagged.** Added
vitest coverage for (a) the three-case ``/voice`` slash output
in ``createSlashHandler.test.ts`` and (b) the
``applyDisplay → voice.record_key`` hydration + omit-setter
back-compat paths in ``useConfigSync.test.ts``. Plus regression
cases for every false-fire scenario above.
Suite: 575/575 green, tsc --noEmit clean.
* fix(tui): address Copilot round-2 review on #19835
Three tightenings on the surface introduced in the round-1 fix:
* **``/voice tts`` reset custom bindings to Ctrl+B.** The ``tts`` branch
of ``voice.toggle`` omitted ``record_key`` from its response, so the
frontend's ``r.record_key ?? 'ctrl+b'`` coerced a user's custom
binding back to the default on every TTS toggle. Two-sided fix:
the backend now includes ``record_key`` on the ``tts`` branch (parity
with ``status``/``on``/``off``), and the slash handler only pushes
frontend state when the response actually carries ``record_key`` —
belt-and-suspenders against any future branch forgetting to include
it.
* **``super+b`` / ``win+b`` / ``cmd+b`` displayed "Cmd+B" on Linux and
Windows.** ``formatVoiceRecordKey`` rendered ``mod === 'super'`` as
``Cmd`` universally, which told non-mac users the wrong modifier to
press even though ``isVoiceToggleKey`` matched the right event bits.
Gate the label to ``isMac`` so non-mac renders ``Super+B``.
* **``control+b`` / ``ctrl + b`` lost the macOS Cmd+B fallback.**
``_isDefaultVoiceKey`` keyed off ``parsed.raw`` — so
semantically-equal aliases of the documented default dropped into
the strict branch even though they bind Ctrl+B. Compare on the
parsed spec (mod + ch + named) instead.
Coverage added: Linux ``Super+B`` rendering (and macOS ``Cmd+B``),
``control+b`` / ``ctrl + b`` accepting the Cmd+B fallback on darwin,
``/voice tts`` without ``record_key`` not clobbering cached binding,
and a backend regression asserting every ``voice.toggle`` branch
carries the configured key.

* fix(tui): address Copilot round-3 review on #19835
Three classes of robustness issue caught on the second pass — all
revolve around malformed YAML tipping ``parseVoiceRecordKey`` or
``_voice_record_key`` into a crash instead of the documented
fallback.
* **Parser crashed on non-string YAML scalars.** ``config.get full``
returns raw ``yaml.safe_load`` output, so ``voice.record_key: 1``
or ``voice.record_key: true`` in a hand-edited config would hit
``.trim()`` on a number/bool and throw, breaking startup and
every mtime re-apply. Accept ``unknown`` at the signature, guard
with ``typeof raw !== 'string'``, and fall back to the default.
* **Backend blew up on non-dict ``voice:``.** Same YAML hazard on
the gateway side: ``voice: true`` / ``voice: cmd+b`` left
``_load_cfg().get("voice")`` as a bool/str, so ``.get("record_key")``
raised AttributeError and took every ``voice.toggle`` branch down
with it. Centralised the lookup in a single
``_voice_record_key()`` helper that ``isinstance``-guards both
``voice`` and ``record_key`` and falls back to ``ctrl+b``.
* **Multi-modifier chords silently dropped extras.** The previous
validator only checked the first modifier token, so ``ctrl+alt+r``
silently parsed as ``ctrl+r`` and ``cmd+ctrl+b`` as ``super+b`` —
a typo bound a different shortcut than the user configured.
Reject multi-modifier spellings outright; the classic CLI only
supports single-modifier bindings via prompt_toolkit's ``c-x`` /
``a-x`` rewrite, so this matches CLI parity.
Coverage added:
* ``parseVoiceRecordKey`` fallback on ``1`` / ``true`` / ``null`` /
``undefined`` / ``{}``.
* ``parseVoiceRecordKey`` fallback on ``ctrl+alt+r`` /
``cmd+ctrl+b`` / ``alt+ctrl+space``.
* ``test_voice_toggle_handles_non_dict_voice_cfg`` exercises
every non-dict ``voice:`` shape (bool, str, None, int, list) and
asserts each falls back to ``record_key: 'ctrl+b'``.
Suite: 581/581 TUI vitest green, 3/3 backend voice tests green,
tsc --noEmit clean.
* fix(tui): address Copilot round-4 review on #19835
Four final corners of the voice.record_key surface:
* **Bare-char configs silently coerced to ``ctrl+<key>``.** A config
like ``voice.record_key: o`` / ``space`` / ``escape`` fell through
to the default ``mod = 'ctrl'`` and silently bound Ctrl+O, while
the classic CLI's prompt_toolkit would bind the raw key (no
rewrite) — so the two runtimes silently disagreed on what "o"
means. Require an explicit modifier; bare-char configs fall back
to the documented Ctrl+B default.
* **Reserved ctrl+<letter> bindings would never fire.**
``useInputHandlers()`` intercepts ``ctrl+c`` (interrupt),
``ctrl+d`` (quit), and ``ctrl+l`` (clear screen) before the voice
check runs, so those configs would be advertised in /voice
status but the advertised shortcut never actually triggers
push-to-talk. Added ``_RESERVED_CTRL_CHARS`` at parse time so
the user gets the documented default instead of a dead shortcut.
(``alt+c``, ``cmd+l``, etc. are not intercepted and stay usable.)
* **``_load_cfg()`` root itself may be a non-dict.**
``_voice_record_key()`` isinstance-guarded the ``voice`` subkey
but not the root — a malformed config.yaml that collapsed to a
scalar/list at the top level (``config.yaml: true`` or ``[]``)
would still raise on ``.get("voice")``. Added the top-level
guard too so every malformed shape falls back to ``ctrl+b``.
* **Stale header comment on ``isVoiceToggleKey``.** The doc-comment
still claimed "On macOS we additionally accept the platform
action modifier (Cmd) for the configured letter" even though the
implementation gates the Cmd fallback to the documented default
only. Rewrote to match.
Coverage added:
* ``parseVoiceRecordKey`` fallback on bare chars (``o``, ``b``,
``space``, ``escape``).
* ``parseVoiceRecordKey`` fallback on ``ctrl+c`` / ``ctrl+d`` /
``ctrl+l``; positive case for ``alt+c`` / ``cmd+l`` still usable.
* Backend ``test_voice_toggle_handles_non_dict_voice_cfg`` now
exercises 5 non-dict shapes at the YAML root too.
Suite: 583/583 TUI vitest green, 3/3 backend voice tests green,
tsc --noEmit clean.
* fix(tui): address Copilot round-5 review on #19835
Three follow-ups on the voice matcher's modifier + shift discipline:
* **``super`` branch falsely fired on Alt+<key> / bare Esc on macOS.**
``isVoiceToggleKey`` accepted ``isMac && key.meta`` as a Cmd
fallback for the ``super`` modifier — but hermes-ink sets
``key.meta`` for plain Alt/Option AND for bare Escape on some
macOS terminals. A ``cmd+b`` config silently fired on Alt+B;
``cmd+space`` on Alt+Space; ``cmd+escape`` on bare Esc. Drop the
fallback and require the literal ``key.super`` bit. Legacy-
terminal users who need Cmd should upgrade to a kitty-protocol
terminal or bind ``alt+X`` explicitly.
* **Shift bit was never checked.** The parser rejects multi-
modifier configs like ``ctrl+shift+tab``, but the runtime
matcher didn't check ``key.shift`` — so ``ctrl+tab`` also fired
on Ctrl+Shift+Tab and ``alt+enter`` on Alt+Shift+Enter.
Early-return on ``key.shift === true`` so the runtime only fires
the exact chord the user configured.
* **Test leaked ``HERMES_VOICE=1`` into later tests.**
``voice.toggle`` action=on writes to ``os.environ`` directly
(CLI parity, runtime-only flag); ``test_voice_toggle_returns_
configured_record_key`` dispatched action=on without letting
monkeypatch take ownership of the var first. Any later test
that read voice mode in the same Python process could inherit a
stale enabled state. Added ``monkeypatch.setenv("HERMES_VOICE",
"0")`` up front so monkeypatch restores the original value at
teardown.
Coverage added:
* ``cmd+b`` / ``cmd+space`` / ``cmd+escape`` do NOT fire on
``key.meta``-only events on darwin.
* ``ctrl+tab`` / ``alt+enter`` / ``ctrl+o`` reject matches when
``key.shift`` is held; sanity cases without Shift still fire.

tsc --noEmit clean.
* fix(tui): address Copilot round-6 review on #19835
Three classes of modifier-discipline tightening + one config-surface
honesty fix:
* **Default ``ctrl+b`` Cmd fallback leaked Alt+B.** The default's
macOS Cmd+B muscle-memory path used ``isActionMod(key)``, which
returns ``key.meta || key.super`` on darwin. hermes-ink also
reports plain Alt as ``key.meta``, so Alt+B silently fired the
default binding. Replaced with strict ``isMac && key.super ===
true`` — kitty-style Cmd+B still works, Alt+B correctly
rejected. Legacy-terminal mac users (Terminal.app without
CSI-u) now get raw Ctrl+B only; the documented default still
works everywhere.
* **ctrl / super branches accepted extra modifier bits.** The
parser rejects multi-modifier configs like ``ctrl+alt+o``, but
the runtime matcher was permissive — ``ctrl+o`` fired on
Ctrl+Alt+O / Ctrl+Cmd+O, and ``super+b`` fired on Cmd+Alt+B /
Ctrl+Cmd+B. Added strict ``!key.alt && !key.meta && key.super
!== true`` on ctrl, and ``!key.ctrl && !key.alt && !key.meta``
on super, so the runtime only fires the exact chord the parser
would let you configure.
* **Dropped ``cmd`` / ``command`` aliases.** They parsed to
``super`` and rendered as ``Cmd+X``, but legacy macOS terminals
report Cmd as ``key.meta`` (same signal as Alt), so a
``cmd+o`` config was advertised as working but never actually
fired on Terminal.app-without-CSI-u. That recreated the
"displayed shortcut does not work" problem this PR was meant to
remove. Users who want the platform action modifier spell it
``super`` / ``win`` — that matches the unambiguous ``key.super``
bit, and kitty-style macOS terminals render it as ``Cmd+X`` via
platform-aware formatter.
Coverage updated:
* Default ctrl+b no longer fires on Alt+B via ``key.meta`` leak;
raw Ctrl+B and kitty-style Cmd+B still fire.
* ``ctrl+o`` rejects Ctrl+Alt+O / Ctrl+Cmd+O / Ctrl+Meta+O chords.
* ``super+b`` rejects Cmd+Alt+B / Cmd+Meta+B / Ctrl+Cmd+B chords.
* ``cmd+b`` / ``command+b`` / ``meta+b`` all fall back to the
documented default at parse time (joined the ambiguous-mac-mod
rejection class).
* Round-2 expectations that asserted ``cmd+b`` parsed as super
and accepted ``key.meta`` on darwin updated to reflect the new
stricter contract.

* fix(tui): address Copilot follow-up on wire typing + escape precedence
Two follow-ups from the latest Copilot pass:
* **Config wire typing honesty (`gatewayTypes.ts`)**
`config.get full` forwards raw `yaml.safe_load()` output, so
`voice.record_key` can be any scalar/container when hand-edited.
Typing it as `string` suggests a normalized contract that the
backend does not guarantee and makes unsafe callers more likely.
Change `ConfigVoiceConfig.record_key` to `unknown` with an
explicit comment that callers must normalize at runtime.
* **Escape-based voice bindings were swallowed before voice check**
`useInputHandlers()` handled `key.escape` for queue-edit cancel and
selection clear before `isVoiceToggleKey(...)`, so configured
`ctrl+escape` / `alt+escape` / `super+escape` chords were advertised
but never toggled recording in those UI states.
Add an early escape+voice check before generic Esc handlers so
escape-based voice bindings win when configured, while plain Esc
behavior remains unchanged.
Also updated PR #19835 description text to remove stale cmd/command
alias claims and match the current parser contract.
* fix(tui): pass configured voice shortcut through TextInput layer
Thread the live parsed voiceRecordKey into TextInput so configured voice.record_key chords bubble to useInputHandlers instead of being consumed as editor input. This removes the last hardcoded Ctrl+B pass-through in the composer path while preserving existing global control chord behavior.
* fix(tui): require explicit alt bit for escape-based alt chords
Hermes-ink reports bare Escape as meta=true+escape=true on some terminals, so a configured alt+escape binding was firing on bare Esc. Require an explicit key.alt bit when the configured named key is escape so plain Esc stays plain Esc; kitty-style alt+escape still fires.
* fix(tui): harden voice.record + TextInput paste + super-mod reserved list
Three round-7 Copilot follow-ups on #19835:
- voice.record start handler used _load_cfg().get('voice', {}).get(...) without
shape checks, so malformed YAML (bool/scalar/list) returned 5025 instead of
using VAD defaults. Centralized _voice_cfg_dict() helper and type-guarded
silence_threshold/silence_duration with numeric fallbacks.
- TextInput pass-through check moved above paste/copy handling so configured
voice chords (ctrl+v / alt+v / cmd+v) beat the composer's paste/copy
defaults.
- parser now also rejects super+{c,d,l,v} — on macOS those are
copy/exit/clear/paste and would be advertised in /voice status but never
actually toggle recording.

- Revert ctrl+x addition to _RESERVED_CTRL_CHARS (landed via Copilot Autofix
commit 731ec86): ctrl+x is only claimed during queue-edit
(queueEditIdx !== null), so voice works the rest of the session and
matches CLI ctrl+<letter> parity.
- Gate super+{c,d,l,v} reservation to isMac. Linux/Windows TUI globals key
off Ctrl, so kitty/CSI-u super+<letter> configs don't collide on non-mac
and should stay usable.
- applyDisplay() now skips setVoiceRecordKey when cfg is null so one
transient quietRpc() failure after a config edit doesn't clobber the
cached binding back to Ctrl+B until the next successful poll.
New coverage:
- parseVoiceRecordKey preserves ctrl+x on linux
- super+{c,d,l,v} rejected on darwin, allowed on linux
- applyDisplay(null, ...) leaves voiceRecordKey untouched
* fix(cli,tui): normalize voice.record_key aliases across CLI + TUI for parity
Round-9 Copilot review on #19835: TUI accepted control+/option+/opt+/super+/win+ aliases but the classic CLI only rewrote literal ctrl+/alt+ before handing to prompt_toolkit, so a TUI-valid config silently bound a different (or no) shortcut in the CLI.
- Added normalize_voice_record_key_for_prompt_toolkit() in hermes_cli/voice.py with a single alias table (ctrl/control/alt/option/opt → c-/a-).
- Wired it into all three cli.py sites (_enable_voice_mode hint, _show_voice_status display, and the prompt_toolkit binding in _register_voice_handler).
- /voice status display now renders control+x as Ctrl+X and option+x as Alt+X (canonical casing) to match TUI formatVoiceRecordKey.
- super/win/windows are intentionally left unchanged: prompt_toolkit has no super modifier, so the CLI will reject them loudly at startup rather than silently binding Ctrl+B. Documented this split at both the TUI _MOD_ALIASES comment and the CLI normalizer docstring.
- Added tests covering ctrl/control/alt/option/opt mapping, case-insensitivity, non-string fallback, empty-string fallback, and super/win pass-through.
* fix(cli): port TUI parser contract into CLI voice.record_key normalizer
Round-10 Copilot review on #19835.
hermes_cli/voice.py's normalize_voice_record_key_for_prompt_toolkit() previously did blind substring replacement with no trim/validate step, so the CLI diverged from the TUI parser on:
- whitespace ('ctrl + b' -> 'c- b' instead of 'c-b')
- typoed named keys ('ctrl+spcae' passed through as 'c-spcae' and prompt_toolkit would reject at startup)
- bare-char configs ('o' should fall back, not pass through as 'o')
- multi-modifier chords ('ctrl+alt+r')
- reserved ctrl chars ('ctrl+c/d/l')
- unknown modifiers ('meta+b' / 'shift+b')
- named-key aliases ('return'/'esc'/'bs'/'del' not collapsed to prompt_toolkit canonicals)
Port the TUI parser contract into Python (_VOICE_MOD_ALIASES, _VOICE_NAMED_KEYS, _VOICE_RESERVED_CTRL_CHARS) so one config value binds the same shortcut in both runtimes.
Also added format_voice_record_key_for_status() shared between the PTT hint and /voice status display. Non-string scalars (voice.record_key: true / 1) now surface as 'Ctrl+B' instead of the raw scalar — /voice status no longer advertises a shortcut that can never bind.
Tests: 29/29 in test_voice_wrapper.py, including 11 new regressions covering whitespace, named-key aliases, typos, bare-char, multi-modifier, reserved ctrl, unknown mods, non-string fallback, and formatter contract.
* fix(cli): shape-safe voice config read + graceful super/win fallback
Round-11 Copilot review on #19835.
Two remaining cross-runtime gaps:
1. load_config().get('voice', {}) still assumed voice was a dict, so a hand-edited voice: true / voice: cmd+b at the top level raised AttributeError before the voice UI could start. Added voice_record_key_from_config(cfg) to hermes_cli/voice.py that isinstance-guards both the root and the voice subkey. All three cli.py read sites (_enable_voice_mode hint, _show_voice_status, PTT binding) now use it.
2. The CLI normalizer previously passed super+/win+/windows+ through unrewritten so prompt_toolkit would reject them loudly at startup — but that crash was a worse UX than a silent fallback. Normalizer now returns c-b for those spellings, and the PTT binding site logs a warning so users see why their TUI-only shortcut isn't binding in the CLI.
Coverage: 34/34 in tests/hermes_cli/test_voice_wrapper.py (5 new cases for voice_record_key_from_config + malformed-root + malformed-voice + extractor/normalizer composition).
* fix(cli): self-audit cleanup — remaining voice-config shape safety + doc drift
Self-review of the voice.record_key change set turned up four remaining items Copilot would very likely flag next round:
1. cli.py _voice_start_continuous still read load_config().get('voice', {}).get('silence_threshold') without an isinstance guard, so a hand-edited voice: true / voice: cmd+b (non-dict) raised AttributeError on VAD recording start. Shape-safe coerce the voice dict and numeric-guard silence_threshold/silence_duration.
2. cli.py _enable_voice_mode's auto_tts check had the same bug — fixed with the same isinstance guard.
3. hermes_cli/voice.py module comment on _VOICE_MOD_ALIASES still said super/win/windows 'pass through unchanged and prompt_toolkit's add() call loudly rejects them at startup'. Round 11 changed the normalizer to silently fall back to c-b with a warning at the binding site; updated the comment to match.
4. ui-tui/src/lib/platform.ts header comment had the same stale 'CLI will loudly reject them at startup' claim; updated to 'falls back to the documented default and logs a warning'.
No behavior change on the code paths already covered by test_voice_wrapper.py; the two cli.py fixes are defensive against malformed YAML that previous rounds already hardened in tui_gateway/server.py but missed in the classic CLI.
* fix(cli,tui): round-12 Copilot review — alt-collide on mac, bool-in-int guards, voice UI hardcodes, mtime-reload test
Five round-12 Copilot review items on #19835:
1. platform.ts: hermes-ink reports Alt as key.meta on many terminals; isActionMod on darwin accepts key.meta as the action modifier. So alt+c/d/l get claimed by isCopyShortcut / isAction('d')/'l') before the voice check. Reject those configs at parse time on macOS only (non-mac keeps them usable).
2. cli.py: four remaining hardcoded 'Ctrl+B' sites in voice-facing UI (_get_voice_status_fragments status bar, _voice_start_recording hints, _get_placeholder composer text) were still lying about non-default configs. Added self._voice_record_key_label() shared helper and wired it into all three sites.
3. server.py + cli.py: bool is a subclass of int, so isinstance(silence_threshold, (int, float)) accepted True/False from malformed YAML and forwarded 1/0 to the VAD engine. Exclude bool explicitly so boolean typos fall back to the documented 200 / 3.0 defaults.
4. useConfigSync.ts: extracted the config.get-full fetch+apply body into a shared hydrateFullConfig() helper. Both the initial hydration and mtime-reload paths now use it, so the polling/RPC wiring is exercised by direct unit tests (4 new cases: fresh apply, reapply on new value, transient RPC failure preserves cache, back-compat without voice setter).
5. Added alt+{c,d,l} rejection regressions on darwin + allow on linux, and bool-leak regressions for both silence_threshold and silence_duration in tests/test_tui_gateway_server.py.
Suite: 602/602 TUI vitest, 38/38 backend voice tests, typecheck + lints clean.
* fix(cli): cache voice record-key label at binding time + status-bar coverage
Round-13 Copilot review on #19835.
_voice_record_key_label() was reading live config on every render, which caused two problems:
1. prompt_toolkit registers the push-to-talk binding once at session start (@kb.add(_voice_key)); the binding does NOT re-read config. Editing voice.record_key mid-session would switch the status-bar / placeholder / recording-hint label to the new shortcut while the actual keybinding stayed on the startup chord — reintroducing the display/binding drift this whole PR is fighting.
2. Hot render path: during recording the UI is invalidated every 150ms, so re-loading + deep-merging config on every call added avoidable UI overhead.
Fix: cache the label at the same site that registers the prompt_toolkit binding via new set_voice_record_key_cache(raw_key). _voice_record_key_label() now just returns the cached value (falls back to 'Ctrl+B' before startup). Status/placeholder/hint are always in sync with the live binding; no config reload per render.
Also added 4 regression cases to tests/cli/test_cli_status_bar.py: configured ctrl+<letter> renders in both wide and compact status bars, configured named key (ctrl+space) renders in the recording hint, pre-startup absent cache falls back to Ctrl+B, and malformed configs (bool True) fall through the formatter to Ctrl+B.
Suite: 60/60 test_cli_status_bar + test_voice_wrapper, typecheck + lints clean.
* fix(cli): route /voice on + /voice status through startup-pinned label; mac alt+cdl parity
Round-14 Copilot review on #19835. All three comments legit:
1. _enable_voice_mode still formatted label from live load_config() — mid-session config edit would make /voice on announce the new shortcut while the prompt_toolkit binding stayed the startup chord. Use self._voice_record_key_label() (cached at binding time, round-13) so /voice on cannot drift from the live binding.
2. _show_voice_status had the same bug — /voice status reported live config instead of the pinned startup binding. Fixed the same way.
3. CLI normalizer accepted alt+c/alt+d/alt+l even though the TUI parser rejects them on macOS (Copilot round-12 — hermes-ink reports Alt as key.meta, isActionMod on darwin accepts it, collides with isCopyShortcut / isAction). Added _VOICE_RESERVED_ALT_CHARS_MAC = {c,d,l} gated to sys.platform == 'darwin' so a shared config like option+c falls back to c-b on both runtimes on macOS; non-mac still binds a-c.
Coverage: 4 new tests in test_voice_wrapper.py covering mac alt+cdl rejection, linux alt+cdl allowed, option/opt alias forms, and mac-specific exclusions for other alt letters. 62/62 in voice wrapper + status bar suites.

If a concurrent RPC mutates _sessions while session.delete is iterating
it (e.g. a parallel session.create on the thread pool), the bare except
swallowed the RuntimeError and let the delete proceed against a row
that may still be live. Snapshot via list(_sessions.values()) and
return an error when even that raises, instead of treating "couldn't
check" as "no active sessions."
Single-key confirm matches how the picker already accepts 1-9 to
resume — no separate y/n keymap to learn — and "press d again" is
self-documenting next to the cursor.
Pressing `d` on the highlighted row in the resume picker prompts
`delete? y/n`; `y` deletes the session (DB row + on-disk transcript
files), anything else cancels. The active session is excluded from
deletion server-side.
Adds a new `session.delete` JSON-RPC handler that wraps
`SessionDB.delete_session`, forwarding the per-profile `sessions/`
directory so transcripts get cleaned up alongside the row.
Reset sticky mouse/focus/paste terminal modes before the TUI starts and during graceful shutdown paths so stale tab state from prior crashes cannot poison the next session.
Detect leaked SGR mouse-report fragments in CLI input, strip them, and reset terminal modes in-place so scroll and typing recover without reopening the tab. Add regression tests for escaped, visible, and bare leak forms.
Route Option/Alt or Ctrl wheel input through a gated precision path that scrolls at most one row per short interval, while preserving the existing accelerated behavior for plain wheel input. Keep precision active briefly after modifier release so queued wheel events from the same gesture do not jump into acceleration mid-stream.
Decode Shift, Meta, and Ctrl bits from SGR and legacy X10 wheel event button bytes so TUI input handlers can distinguish modified wheel gestures from plain scrolling.
* fix(tui): offload manual compaction RPC
Route TUI session compression through the existing long-handler pool so slow compaction does not block other gateway RPCs.
* fix(tui): show compaction progress immediately
Print a local status line before the compress RPC starts so slow manual compaction does not look like a no-op.
* feat(tui): rich /compress feedback parity with CLI
Show pre-compaction message count and rough token estimate immediately, emit a status update so the bottom bar reflects ongoing compaction, and report a multi-line summary (headline + token delta + optional note) using the shared summarize_manual_compression helper.
* fix(tui): show live compaction estimate in transcript
Mirror compression progress status into the transcript so users see the backend message count and token estimate while /compress is still running.
* fix(tui): single live compaction line with spinner glyph
Drop the redundant local "compressing context..." placeholder and prefix the live backend status line with a braille spinner glyph so /compress reads as a single in-progress row.
* fix(tui): address review nits on /compress feedback
Reuse the precomputed token estimate inside _compress_session_history so the gateway does not redo the O(n) work while holding history_lock, keep the status bar pinned during long manual compactions instead of auto-restoring after 4s, and drop the redundant noop bullet that doubled with the system role glyph.
* fix(tui): release history_lock during compaction LLM call
Move the snapshot/commit pattern into _compress_session_history so the lock is held only across the in-memory bookkeeping, not during agent._compress_context. Also emit a final neutral status update from session.compress so the pinned compressing indicator clears even on errors.
* fix(tui): rebuild prompt cleanly + sync session_key after compress
Pass system_message=None so AIAgent._compress_context rebuilds the system prompt without nesting the cached identity block. Reuse the handler's pre-snapshotted history inside _compress_session_history to avoid a second O(n) copy under the lock. After compaction, when AIAgent._compress_context rotates session_id, sync the gateway session_key, migrate approval notify + yolo state, restart the slash worker, and clear the stale pending title. Mirrors HermesCLI._manual_compress.
* Avoid /compress lock re-entry in slash side effects.
Stop pre-locking history before _compress_session_history in slash command mirroring, keep session-key sync parity with manual compression, and add a regression test that asserts /compress is invoked without holding history_lock.
* fix(tui): word-wrap composer input
Wrap composer input at word boundaries and anchor the good-vibes heart to the full composer row.
* test(tui): cover composer word wrap edge
Add regression coverage for moving the next word instead of splitting it at the composer edge.
* fix(tui): honor launch toolsets
Carry chat --toolsets through the TUI launcher so TUI sessions use the same per-session tool scope as the classic CLI.
* fix(tui): parse top-level toolsets flag
Allow top-level hermes --tui --toolsets to reach the implicit chat session, matching chat subcommand behavior.
* fix(tui): validate launch toolsets
Filter invalid HERMES_TUI_TOOLSETS entries and fall back to configured CLI toolsets when the override contains no valid toolsets.
* fix(tui): avoid config load for builtin toolsets
Honor built-in HERMES_TUI_TOOLSETS values before loading config and treat all/* as the all-toolsets sentinel.
* fix(cli): honor toolsets in oneshot mode
Forward top-level --toolsets into oneshot agent construction so the flag is not silently ignored outside the TUI path.
* fix(cli): validate oneshot toolsets
Reject invalid-only oneshot toolset overrides before output redirection and clarify TUI fallback warnings.
* fix(cli): preserve all-toolsets sentinel
Map explicit all/* oneshot toolset overrides to the all-toolsets sentinel and replace locals() checks in TUI toolset loading.
* fix(cli): warn on extra all-toolset entries
Warn when all/* toolset overrides include additional ignored entries so typos are still visible.
* fix(tui): honor plugin toolset overrides
Discover plugin toolsets before rejecting unresolved explicit toolset overrides and read raw config for MCP name validation.
* fix(tui): reuse toolset argument normalizer
Share top-level TUI toolset argument parsing with the oneshot path to avoid duplicate normalization logic.
* fix(cli): reject disabled mcp toolsets
Validate explicit toolset overrides against enabled MCP servers only and clarify top-level toolset flag help.
* fix(cli): distinguish disabled mcp from unknown toolsets
Report disabled MCP servers separately from unknown toolset entries and stub plugin discovery in invalid-name tests for determinism.

Copilot caught that clearing inFlight on a transient normal-memory tick could
allow a second dump/eviction to start before the first async tick completed.
Only clear dumped on normal; let the in-flight tick's finally remove its own
level.
Tests:
- cd ui-tui && npm run type-check && npm run build
Finish the Copilot review cleanup for lazy prompt submission:
- prompt.submit now claims session.running before returning success, preserving
the existing RPC-level session busy error so the frontend can queue.
- agent-init timeout/failure now emits a normal error event instead of writing a
second JSON-RPC response for an already-settled request id.
Tests:
- python -m py_compile tui_gateway/server.py tui_gateway/entry.py
- cd ui-tui && npm run type-check && npm run build
- scripts/run_tests.sh tests/tui_gateway/test_protocol.py::test_sess_found tests/tools/test_code_execution_modes.py tests/tools/test_code_execution.py
- cd ui-tui && npm test -- --run src/__tests__/useSessionLifecycle.test.ts src/__tests__/useConfigSync.test.ts
Respond to Copilot's lazy-start review: session metadata/history/usage do not
need a constructed AIAgent, so keep them on the no-wait session path. This
preserves the deferred startup model and avoids blocking simple session RPCs on
agent initialization.
Tests:
- python -m py_compile tui_gateway/server.py tui_gateway/entry.py
- cd ui-tui && npm run type-check && npm run build
- scripts/run_tests.sh tests/tui_gateway/test_protocol.py::test_sess_found tests/tools/test_code_execution_modes.py tests/tools/test_code_execution.py
