* feat(tui): HERMES_DEV_CREDITS live-spend dev readout (L0 tracer for usage-aware credits)
L0 of the usage-aware-credits feature: a dev-only, env-gated tracer that
exercises the real header -> CreditsState -> TUI pipe end-to-end behind
HERMES_DEV_CREDITS, de-risking the L1/L5 build before the notice policy exists.
- agent/credits_tracker.py: CreditsState + parse_credits_headers (headers are
strings -> paid_access via == "true", never bool(); retain-last-known; only
subscription_micros may be negative; *_usd kept verbatim).
- run_agent.py: _capture_credits / get_credits_state / get_credits_spent_micros,
session-start baseline latch, + dev-gated "credits" capture log.
- agent/chat_completion_helpers.py: capture on the streaming response.
- agent/agent_init.py: init _credits_state + _credits_session_start_micros.
- tui_gateway/server.py: _get_usage emits dev_credits_spent_micros only when flagged.
- ui-tui appChrome.tsx / types.ts: cents delta status segment + "(dev credits)" banner.
Off by default; silent for normal users. Validated live against staging
(capture log delta matches the TUI segment). Throwaway consumer (readout/log/
banner); credits_tracker + the capture plumbing are the real feature foundation.
* test(credits): lock parser under 9-state matrix + harden validation (L2)
Add tests/agent/test_credits_tracker.py with 92 tests covering the 9-state
matrix (healthy, sub_90pct, grant_exhausted, purchased_only, tool_pool_free,
depleted, debt, missing, no_org) plus validation edge cases: version strict==1
with warn-once latch for v>1, bool-string trap (paid_access/tool_pool_gated_off
== "true"/"false", never bool()), half-pair subscription limit treated as
both-absent while parse succeeds, USD regex ^-?\d+\.\d{2}$, non-int micros
→ None, negative non-subscription micros → None, as_of_ms junk → None, zero
limit ZeroDivision guard.
Harden agent/credits_tracker.py to match the spec:
- Add tool_pool_micros/tool_pool_gated_off/from_header fields to CreditsState
- Add depleted property (== not paid_access, never remaining==0)
- Change used_fraction guard to key off subscription_limit_micros (the actual
denominator) not denominator_kind (metadata)
- Replace fail-soft _safe_int with a sentinel-returning variant; full validation
now returns None on any malformed field rather than silently defaulting
- Add module-level warn-once latch for version > 1
- Add USD regex validation; add denominator_kind allow-list check
- Parse x-nous-tool-pool-* prefix headers (not x-nous-credits-tool-pool-*)
* feat(credits): notice spine — AgentNotice + notice_callback/notice_clear_callback + TUI binding (L1)
L1 of usage-aware credits: the driver-agnostic notice delivery spine that L4's
policy will fire through and L5's TUI render will consume.
- agent/credits_tracker.py: AgentNotice dataclass (text/level/kind/ttl_ms/key/id;
kind defaults "sticky", kept TTL-expressive for a future config seam).
- run_agent.py: AIAgent gains notice_callback + notice_clear_callback slots and
_emit_notice / _emit_notice_clear emitters (swallow all callback errors — a
notice must never break the agent loop; no-op when unbound).
- agent/agent_init.py: thread both callbacks through init_agent.
- tui_gateway/server.py: bind both in _agent_cbs → notification.show / notification.clear
WS events (snake_case payload, matching the existing gateway-event convention).
- ui-tui/src/gatewayTypes.ts: notification.show / notification.clear arms on GatewayEvent.
- tests/run_agent/test_notice_spine.py: 15 tests (emitter fire + fail-open + no-op,
signature threading, TUI binding payload shape).
Messaging push is out of v1 (binds neither callback). CLI binding + the TUI render/
decode land with L4 (firing) and L5 (render) so turn-end flush is wired correctly.
* feat(credits): threshold reconciliation policy + tests (L4.1)
* feat(credits): wire threshold policy into capture + latch (L4.2)
After a fresh header parse, _capture_credits runs evaluate_credits_notices against
the agent's _credits_latch and emits the result — clears first, then shows (so a
recovered depletion clears before the "restored" success lands, and depleted wins
the latest-wins slot). Gated on a bound notice_callback: messaging (no callbacks)
still caches state for /usage but runs no policy. Parse stays fail-open (miss →
keep last-known); the eval/emit path warns on failure rather than swallowing, so a
depletion-notice bug can't vanish silently.
- run_agent.py: _capture_credits split into parse (swallow→miss) + policy (warn);
latch lazy-guarded (object.__new__ safety).
- agent/agent_init.py: init agent._credits_latch = {"active": set(), "seen_below_90": False}.
* feat(tui): render credits notices in the status bar (L5, Strategy B)
The TUI now renders the notification.show / notification.clear gateway events the
agent emits — a level-colored notice overrides the status/verb slot when not busy.
- Notice state machine on turnController (pendingNotice + dedicated noticeTimer +
show/clear/applyNotice/flushPendingNotice/clearNoticeState). createGatewayEventHandler
decodes the events and delegates.
- Render priority busy > notice > status (appChrome StatusRule); notice text rendered
verbatim (its glyph comes from the policy), shrinkable so it never clips model│ctx;
dev-credits banner + Δ segment preserved. UiState.notice is snake_case (matches wire).
- Busy-wins: a notice arriving mid-turn is held and flushed at the THREE turn-end sites
(recordMessageComplete / interruptTurn / recordError) — never idle(), which reset()
also calls (would leak across sessions); reset() clears instead.
- Dedicated noticeTimer (never statusTimer); TTL starts on visibility with an id-guard;
latest-wins cancels the prior timer; clear is key-matched (no-op on mismatch); a sticky
survives a turn (flush no-ops with no pending); session reset clears (no cross-session leak).
- 20 tests (handler/turnController logic incl. R3-C2 timer isolation + render priority).
* feat(credits): cold-start seed for new Nous sessions (L3)
A genuinely-new Nous session has no inference header yet, so seed credits state from
the authoritative GET /api/oauth/account snapshot at session start (in the new-session
branch of _restore_or_build_system_prompt — inline, since the on_session_start plugin
hook gets no agent reference). The seed runs the shared notice policy, so a session that
opens already depleted warns IMMEDIATELY rather than only after the first turn.
- Maps the nested account fields (paid_service_access → paid_access; total_usable /
subscription / purchased on paid_service_access_info; rollover on subscription), each
None-guarded; float dollars → micros via round(d*1e6), *_usd left "" (render formats
from micros — never synthesize a verbatim usd from a float).
- Magnitudes-only: no monthlyCredits on the endpoint → subscription_limit_* unset →
used_fraction None → no warn90 from the seed (% only once a header lands, per D-E).
- Provider-guarded to Nous; fail-open (any error leaves _credits_state None, never
blocks startup); paid_access unknown ⇒ True (never falsely depleted).
- run_agent.py: extracted the warm-path policy/emit block into a shared
_emit_credits_notices() so capture and the seed fire notices identically.
* feat(credits): /usage Nous credits magnitudes view + recovery trigger (L6)
Add Nous credit dollar magnitudes to /usage (subscription / top-up / total
+ rollover + renewal + portal CTA), magnitudes-only per v1 (no % until the
account endpoint exposes a denominator). Reuses the existing account-usage
render machinery via a new pure build_nous_credits_snapshot() that maps a
NousPortalAccountInfo to an AccountUsageSnapshot; no nous branch is added to
fetch_account_usage (keeps the per-provider boundary intact).
CLI /usage also doubles as a depletion-recovery trigger: a force_fresh
account fetch, kept in a SEPARATE local so it never clobbers the
header-sourced agent._credits_state (which alone carries used_fraction). If
paid access recovered while credits.depleted is latched and a notice
consumer is bound, it reuses agent._emit_credits_notices() to clear it.
Gateway /usage displays magnitudes only — messaging binds no notice
consumer, so it performs no recovery emit.
Fail-open throughout: any portal hiccup leaves /usage unaffected.
* refactor(credits): dedupe HERMES_DEV_CREDITS flag parse via shared helpers
The dev-flag truthy check was inlined in three places. Replace with the shared
utils.is_truthy_value (run_agent.py, tui_gateway/server.py — also drops a
redundant inline `import os`) and a hoisted DEV_CREDITS_MODE export in
ui-tui/src/config/env.ts (consumed by appChrome, which also stops recomputing the
env check on every render). Behaviour-preserving; identical truthy set.
* fix(credits): cut dead /usage recovery trigger + bound portal fetches (L6 review)
Adversarial review found the /usage depletion-recovery trigger dead AND broken:
the CLI binds no notice_clear_callback, the TUI runs /usage in a separate
slash-worker subprocess (its own agent/latch), and the no-clobber rule made it
evaluate stale paid_access anyway. Recovery already happens on the next inference
(warm path), so the trigger was redundant — remove it and stop the depleted
notice over-promising.
- cli.py: remove the dead recovery block; bound the /usage portal fetch with a
10s wall-clock timeout (ThreadPoolExecutor) like the per-provider fetch —
urllib's per-socket timeout is not a wall-clock guarantee.
- agent/credits_tracker.py: reword the depleted CTA to "run /usage for balance"
(no false recovery promise; /usage shows fresh magnitudes, sticky clears next turn).
- agent/conversation_loop.py: same wall-clock timeout on the cold-start seed fetch
so a stalled portal can't hang session startup; tidy its time import.
* chore(credits): dev notice-state fixtures (HERMES_DEV_CREDITS_FIXTURE)
Throwaway dev scaffolding to exercise the notice pipeline without real spend or
Redis seeding. Set HERMES_DEV_CREDITS_FIXTURE to a state name (healthy / sub_90pct
/ grant_exhausted / depleted / clear) or a file path whose contents name a state
(re-read each turn → flip states live for recovery testing). _capture_credits
injects the chosen CreditsState instead of parsing real headers and runs the
shared notice policy. Deletable with the rest of the HERMES_DEV_CREDITS scaffolding.
* feat(credits): /usage monthly-grant % gauge
The portal /api/oauth/account subscription block now carries monthly_credits
(the per-period grant allowance, the % denominator). The consumer parsed
monthly_charge but dropped monthly_credits, so /usage stayed magnitudes-only.
Capture monthly_credits into NousPortalSubscriptionInfo + _subscription_from_payload.
build_nous_credits_snapshot emits a Subscription usage window (real % used, routed
through the existing render machinery) when monthly_credits is a finite positive
denominator and credits_remaining is finite and <= cap; otherwise it degrades to
magnitudes-only (older portals, rollover-over-cap, or non-finite payloads).
Guards (adversarial-review-driven): reject non-finite operands (json.loads parses
bare NaN/Infinity by default → would render $nan + a false 100% used), reject
bools, guard div-by-zero (cap>0), and suppress the gauge when remaining > cap
(rollover spanning the period makes the cap a nonsensical denominator → the
$X-of-$Y detail would read as a contradiction). Debt (remaining<0) clamps to 100%.
Money rule preserved: the ratio + magnitudes are computed from numeric float
account fields via display formatting, never by parsing a server *_usd string
(there are none on these dataclasses).
13 gauge tests added (tests/agent/test_nous_credits_gauge.py).
* fix(credits): show /usage Nous block whenever a Nous account is present
/usage runs in a slash-worker subprocess whose resolved inference provider is
often not "nous" even when the user has a Nous account, so gating the Nous
credits block on (provider == "nous") hid it entirely — the account data was
fully available but never rendered.
Gate instead on "a Nous account is logged in": a cheap local auth-state lookup
(get_provider_auth_state('nous') has an access_token) decides whether to attempt
the portal fetch, regardless of which provider inference runs on. In the gateway
the block is also lifted out of the 'if provider:' scope so a Nous-credentialled
user with another (or no) resident inference provider still sees their balance.
Fail-open and the per-fetch wall-clock timeout are preserved.
* fix(credits): show /usage Nous block when there's no live agent (TUI slash-worker)
In the TUI, /usage runs in a slash-worker subprocess that resumes the session
WITHOUT building an agent (self.agent is None), so _show_usage early-returned
"(._.) No active agent" before ever reaching the Nous credits block — which is
agent-independent (a portal fetch gated on Nous auth-state). Extract the block
into _print_nous_credits_block() and run it at the no-agent / no-calls
early-returns too (returns True if it printed, so the fallback message only
shows when there's genuinely nothing).
Verified live against staging: the block + monthly-grant gauge now render in the
slash-worker /usage path (previously hidden). The plain CLI REPL + messaging
paths are unchanged (they have a live agent).
* feat(credits): escalating 50/75/90 usage bands (single status line)
Replace the lone 90%-used warning with three escalating bands (50 info, 75 warn,
90 warn) shown as ONE status-bar line: it displays the highest band the
subscription grant has crossed, replaces the line as usage climbs, steps back
down on recovery, and clears below 50%. No stacking, no per-turn churn.
Bands live in a tunable CREDITS_USAGE_BANDS list; the policy derives everything
from it. Single notice key (credits.usage) with a usage_band latch field so the
notice only re-emits when the band actually changes. The crossing gate
(seen_below_90) is preserved so a fresh live session that opens mid-range stays
quiet until it has been observed below the lowest band (cold-start primes it when
it wants an open-high warning). Denominator math unchanged: % = subscription
grant burn (cap - grant_remaining)/cap, clamped [0,1]; top-up never moves the %.
Migrated test_credits_policy.py to the new key + added TestUsageBands (climb,
step-down, recovery-clear, idempotent, inclusive boundaries).
* feat(credits): hydrate notices at session OPEN via shared seed (TUI + first-turn)
Notices previously only fired inside a conversation turn (first message), so a
session that opened already depleted / past a usage band showed nothing at
'ready'. Extract the cold-start seed into a shared seed_credits_at_session_start()
and call it (a) in the TUI/desktop agent build right after the notice callback is
wired (fires at 'ready', before any message) and (b) as the first-turn fallback in
conversation_loop. Idempotent (skips once _credits_state exists) and fail-open.
The seed now maps monthly_credits -> subscription_limit_micros +
denominator_kind='subscription_cap', so used_fraction is computable at seed time
and usage-band warnings (not just depletion) hydrate on open. Primes the crossing
latch so a session opening already in a band warns immediately. Degrades to
depletion-only when monthly_credits is absent (older portals).
Adds test_credits_cold_start.py covering open-at-band, depletion, debt, no-cap
degradation, and the shared seed (fires/idempotent/skips-non-nous).
* feat(credits): /usage monthly-grant % gauge + fixture support + TUI surfacing
agent/account_usage.py: build_nous_credits_snapshot emits a subscription %% gauge
when the portal supplies a positive, finite monthly_credits denominator with
remaining <= cap (guards reject NaN/Infinity and rollover-over-cap, which would
render $nan or a contradictory $X-of-$Y); degrades to magnitudes-only otherwise.
Adds shared nous_credits_lines() (auth-gated, wall-clock-bounded portal fetch) so
the CLI and TUI /usage render the same block, and _snapshot_from_credits_state()
so HERMES_DEV_CREDITS_FIXTURE drives /usage offline too.
TUI: session.usage RPC carries credits_lines (agent-independent) and the /usage
panel renders them regardless of API-call count or resume state — previously the
TUI's separate /usage implementation only showed token counts.
Money rule preserved: %% and magnitudes come from numeric float account fields via
display formatting, never by parsing a server *_usd string.
* feat(credits): CLI REPL inline notices (parity with TUI)
The plain CLI agent bound no notice callbacks, so credit notices were TUI-only.
Bind notice_callback/notice_clear_callback on the CLI AIAgent; _on_notice renders
a single level-colored line above the prompt (error red / warn yellow / success
green / info dim) via _cprint, and seed credits at session open so a depletion or
usage-band warning shows before the first message — the same hydration the TUI
got. _on_notice_clear is a no-op (the REPL prints lines, no persistent slot).
* test(credits): add sub_50pct + sub_75pct dev fixtures for the new usage bands
The fixture set jumped 10%% -> 90%%; add sub_50pct (uf 0.5 -> band 50 info) and
sub_75pct (uf 0.75 -> band 75 warn) so the new escalating bands are exercisable
via HERMES_DEV_CREDITS_FIXTURE across all three surfaces (notice, session-open
seed, /usage gauge).
* fix(credits): usage-band notice clears on next prompt (not sticky-forever)
A 50/75/90 usage heads-up was sticky and camped the status bar indefinitely. Clear
the visible credits.usage notice when a new turn starts (startMessage), so it shows
until your next prompt then yields. The server latch is unchanged, so it won't
re-nag at the same band — it only re-shows when the band actually changes (climb)
or clears when usage drops below the lowest band. Depletion stays sticky.
* refactor(credits): consolidate the /usage credits block behind nous_credits_lines()
The CLI (_print_nous_credits_block) and the messaging gateway (_handle_usage_command)
each re-implemented the auth-gate + portal fetch + render, and both bypassed the
dev-fixture short-circuit that only the TUI honored — so /usage ignored
HERMES_DEV_CREDITS_FIXTURE on the CLI and in chat. Route both through the shared
agent.account_usage.nous_credits_lines() helper: one fetch/render path, one auth
gate, and the fixture works on every surface (~60 fewer duplicated lines).
The gateway usage test recorded only the last asyncio.to_thread call; /usage now
dispatches both the account fetch and the credits fetch, so it records every call
and matches the account fetch by its provider arg.
* fix(credits): keep the /usage gauge type-safe and log its fail-open path
_is_finite_num is now a TypeGuard[float], so the type checker narrows the gauge
operands (monthly_credits / credits_remaining) and the magnitudes passed to
_fmt_usd through it — no more None-operand warnings on the arithmetic. Add a debug
breadcrumb on the nous_credits_lines portal-fetch fail-open so a dead /usage block
is diagnosable in agent.log without a dev flag.
* fix(credits): harden the header tracker — prod-leak gate, hot-path probe, fire-and-forget seed
- Prod-leak guard: dev fixtures (HERMES_DEV_CREDITS_FIXTURE) now also require
HERMES_DEV_CREDITS, so a stray fixture var can't surface fabricated balances on a
real account. Matches the documented run workflow (both vars set together).
- Hot-path probe: parse_credits_headers checks for the version sentinel header
before allocating a lowercased copy of the response headers — skips that work on
every non-Nous API call. Behaviour-identical and still case-insensitive.
- Fire-and-forget seed: the real portal fetch in seed_credits_at_session_start now
runs in a daemon thread, so a slow/unreachable portal never delays session "ready"
(previously blocked up to 10s). The dev-fixture path stays synchronous; the thread
re-checks idempotency before hydrating (a live header may land first).
- Diagnostics: debug breadcrumbs on the parse and seed fail-open paths so a crashed
parser / dead seed is distinguishable from a legitimate no-headers miss.
Cold-start tests set HERMES_DEV_CREDITS alongside the fixture to match the gate.
* test(tui): fix env-timing in the StatusRule dev-credits assertion
DEV_CREDITS_MODE is read once at module load (config/env), so mutating
process.env.HERMES_DEV_CREDITS inside the test couldn't flip it — the dev-banner
assertion only passed if the env was exported before vitest started, and failed in a
normal run. Move that assertion to a sibling file that mocks config/env with
DEV_CREDITS_MODE: true (scoped, no module-reset / React-identity hazard).
* test(credits): cover the dev-fixture /usage render and usage-band clear-on-prompt
- _snapshot_from_credits_state (the offline /usage renderer) had no direct test:
lock the gauge math, the verbatim *_usd magnitudes, the depletion line and the
fixture marker, plus the no-cap (no gauge) and None-state cases.
- turnController.startMessage had no test for clearing the credits.usage notice on
the next prompt while leaving credits.depleted sticky.
* feat(credits): deliver credit notices over messaging gateways
Bind notice_callback/notice_clear_callback on the per-turn gateway agent
so usage-band / depletion / restored notices reach Telegram/Discord/Slack/
etc. Previously the messaging gateway bound neither callback, so the agent's
_emit_credits_notices early-returned and a chat user crossing a band got
nothing unless they ran /usage manually.
- render_notice_line(): AgentNotice -> single plaintext line (level glyph +
text), plaintext-only so it renders uniformly without per-platform escaping.
Fail-soft on malformed/empty notices.
- Standalone push for every notice (messaging has no persistent status bar):
route through the shared _deliver_platform_notice rail (honors private/
public delivery + thread metadata), scheduled onto the gateway loop via
safe_schedule_threadsafe from the agent's sync worker thread — same pattern
as _status_callback_sync.
- The fired-once latch lives on the cached (reused-in-place) agent and
persists across turns, so a band crosses once -> one push, no per-turn
re-nag. Re-fires only after idle-eviction rebuilds the agent (a reminder).
- Recovery ('Credit access restored') rides the show path (emitted as a
success notice, not a clear). notice_clear_callback is a no-op: a sent
platform message can't be cleanly retracted.
Tests: render glyph/levels/fail-soft + public/private delivery seam through
_deliver_platform_notice + no-adapter no-op.
* fix(credits): don't double the glyph on messaging notices
render_notice_line prepended a per-level glyph, but the notice policy already
bakes the glyph into the text (and the TUI + CLI render it verbatim) — so every
credit notice over messaging came out doubled ("⚠ ⚠ Credits 90% used",
"⛔ ✕ Credit access paused"). Emit the text verbatim instead; drop the now-dead
level→glyph map.
The render tests fed glyph-less text (and the success case only checked
startswith), so the doubling slipped through. Rework them around the verbatim
contract and add an end-to-end regression that runs real evaluate_credits_notices
output through render_notice_line and asserts the line is returned unchanged.
Two TUI polish fixes.
(1) Right-click copy now clears the highlight.
The right-click handler copied an active selection via onCopySelectionNoClear
(the copy-on-select variant that keeps the highlight during a drag) and never
cleared it, so after right-click-to-copy the selection stayed lit with no
confirmation and a follow-up right-click re-copied the stale range instead of
pasting. A successful right-click copy now clears the selection and notifies;
if the copy fails (no clipboard path) the highlight survives and we fall back
to the right-click paste handler, exactly as before.
(2) Group transcript blocks so boundaries read clearly.
Model replies, reasoning/tool trails, and system/error notes rendered with no
vertical separation, so distinct block types butted together and were hard to
scan. Group adjacent blocks by kind: one blank line opens only where the visual
group changes (model prose <-> reasoning/tool trails <-> notes), while a run of
same-kind blocks renders flush. The rule lives in domain/blockLayout.ts
(messageGroup + hasLeadGap) and is applied intrinsically in MessageLine via a
`prev` prop, which fixes the things ad-hoc per-block margins kept breaking:
- Streaming stability: the gap is derived from the stable predecessor, never
the live block's own changing text, so the actively-streaming reply computes
the same gap while it streams as the settled segment does once it flushes.
No reflow/jump.
- Transparent empty trails: a trail hidden by /details, or one carrying only a
token tally (the finalDetails segment message.complete appends), renders
nothing and is transparent to grouping (prevRenderedMsg skips it), so there
are no floating gaps, no doubled gap after a prompt, and no padded space
above the final reply. In the default/collapsed modes content-bearing trails
always render, so the grouping is a no-op there.
The virtual-height estimator counts the group-boundary line so scroll math
stays accurate before Yoga remeasures.
ui-tui/src/domain/blockLayout.ts (new), components/messageLine.tsx,
components/streamingAssistant.tsx, components/appLayout.tsx,
lib/virtualHeights.ts, app/useMainApp.ts.
Tests: blockLayout.test.ts (grouping + hidden/empty-trail visibility),
virtualHeights leadGap, app-mouse.test.ts copy behavior. Full ui-tui suite
green apart from 3 pre-existing local/env failures (cursorDrift, ink-resize,
virtualHeights user-prompt-width) unchanged from main.
* feat(tui): single /model command + unified Sessions overlay
Collapse the redundant `/provider` alias so `/model` is the only name
everywhere (it already drove the same 2-step ModelPicker in the TUI).
Merge the separate `/resume` (cold history browser) and `/sessions` (live
switcher) surfaces into one Sessions overlay reached by `/resume`,
`/sessions`, `/session`, and `/switch`. It pins a "+ new" row at the top
(always visible), lists live sessions with status, and lists resumable
history below — dispatching session.activate for live rows vs resume for
cold ones, with close/delete in place. Fixes `/session` opening an empty
live-only switcher and the hidden new-session affordance.
* Potential fix for pull request finding
Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>
* fix(tui): address Copilot review on the Sessions overlay
- Track the armed history-delete by session id instead of row index so the
1.5s live-status poll re-indexing rows can't redirect the second `d` to a
different session.
- Re-add the busy-session guard to immediate `/resume <id>` and `/sessions new`
actions (browsing the bare overlay stays allowed) so resuming/switching can't
corrupt an in-flight turn's streaming/busy state.
* fix(tui): guard cold-resume (not live-switch/new) from the Sessions overlay
Copilot flagged that overlay actions bypassed the busy guard. Only cold
resume actually closes the current session, so only it is guarded — both
from the slash path and now from the overlay (appActions.resumeById).
Switching between live sessions and starting a `+ new` live session keep
the current session running in the background, so they stay unguarded:
that concurrency is the orchestrator's whole purpose. Also dropped the
over-broad guard on `/sessions new` for the same reason.
* fix(tui): address Copilot review (history dedup + desktop /provider)
- The 1.5s poll now re-derives the resumable list from the RAW session.list
results (rawHistoryRef) against the current live set, so a session hidden
while live reappears in history once it closes — instead of being lost
until a full reload. Delete also prunes the raw ref.
- Drop the dead `/provider` entry from the desktop PICKER_OWNED_COMMANDS now
that the alias is gone, so the desktop client no longer advertises it.
* fix(tui): surface session.list errors + keep selection stable across polls
- A garbled session.list response now surfaces an error and preserves the
last good raw history, instead of silently blanking the resumable section.
- The 1.5s poll re-anchors the selection to the same row by session id
(live or history) when the live list grows/shrinks, so the highlight no
longer drifts to a different row mid-interaction.
* fix(tui): degrade session.list independently + cover overlay helpers
- Fetch active_list and session.list via Promise.allSettled so a failing
session.list no longer rejects the whole load: live sessions still render
and only the resumable history degrades (with an error).
- Add unit tests for the new helpers (sessionRowKindAt row ordering,
resumableHistory dedupe, sessionsCountLabel, relativeSessionAge).
* test(tui-gateway): assert /provider alias is gone, /model remains
The CI test_complete_slash_includes_provider_alias asserted the removed
`/provider` alias still autocompleted. Flip it to lock in the removal:
`/pro` no longer offers `provider`, and `/mod` still completes `model`.

The left-content reservation used a flat constant for the busy face,
but its width varies by /indicator style: kaomoji is a wide glyph plus
a rotating verb, while unicode is a bare 1-col braille spinner with no
verb. Reserve the real width via busyIndicatorWidth(style, hasDuration)
so the model stays on-screen across styles without over-reserving the
unbounded elapsed-time tail.
Add a first-class active-session orchestrator for the Ink TUI:
- list, activate, close, and launch live process-local TUI sessions
- hydrate committed and in-flight output when switching sessions
- dispatch a new prompt session from the +new row with session-scoped model picks
- expose a clickable live-session count in the status chrome
- preserve stable row order while initially focusing the current session
- support mouse hit-testing for floating orchestrator overlays
- add backend and frontend regression coverage for the lifecycle and UI helpers
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.
Salvaged from #28942 (adybag14-cyber). Only the Ink TUI half is taken
here — the bundled "termux compatibility note" added to skills_tool.py
in the original PR did not address the actual user-reported bug
(skill_matches_platform() filtering Linux skills out on Termux) and
also regressed the EXCLUDED_SKILL_DIRS set used to prune nested
.venv/site-packages skills.

- ui-tui/src/lib/prompt.ts: single-cell ASCII '>' marker in Termux mode
to avoid ambiguous-width glyph artifacts while typing.
- ui-tui/src/components/appLayout.tsx: suppress profile prefix on
narrow Termux panes (>=90 cols still shows it).
- ui-tui/src/lib/inputMetrics.ts + components/messageLine.tsx +
lib/virtualHeights.ts: termux-aware transcript body width — drop
the desktop 20-col floor on narrow mobile layouts, align virtual
heights with actual rendered width.
- ui-tui/src/components/textInput.tsx: disable fast-echo bypass by
default in Termux to avoid ghosting at soft-wrap boundaries.
HERMES_TUI_TERMUX_FAST_ECHO=1 opts back in.
Tests: ui-tui/src/__tests__/{prompt,termuxComposerLayout,textInputFastEcho}.test.ts
(12 PR-added tests pass; 3 pre-existing wrapAnsi-bundling failures on
main are unrelated.)
The real skill-listing fix on Termux ('android' platform matching
Linux skills) ships as a follow-up commit on this branch.
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): 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.

* 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.
Suite: 579/579 TUI vitest green, 2/2 backend voice tests green,
tsc --noEmit clean.
* 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.
Suite: 585/585 TUI vitest green, 3/3 backend voice tests green,
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.
Suite: 588/588 TUI vitest green, 3/3 backend voice tests green,
tsc --noEmit clean.
* 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.

* fix(tui): round-8 Copilot review — allow ctrl+x, gate super reservations to macOS, preserve voice key on transient RPC failure
Three round-8 Copilot follow-ups on #19835:
- 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.

* 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.
Match classic CLI perceived startup behavior: show the TUI shell and composer
before constructing the full AIAgent. session.create now returns a lightweight
placeholder session with lazy=true and no longer starts _make_agent eagerly.
The first method that needs the agent triggers _start_agent_build() via _sess();
prompt.submit is routed through the RPC worker pool so that the initial wait for
agent construction does not block the stdio dispatcher.
The intro panel renders skeleton rows for tools/skills while the real
session.info payload is absent, then hydrates to the real tools/skills panel once
AIAgent initialization completes. Also skip the startup /voice status probe and
avoid the input.detect_drop RPC for ordinary plain-text prompts to keep early
startup/first-submit paths cheap.
Measurements on macOS Terminal.app:
- Previous full ready p50 after earlier PR commits: ~1537ms
- Lazy skeleton panel p50: ~794ms
- Original baseline full ready p50: ~1843ms
So the visible startup surface is now ~743ms faster than the prior PR state and
~1.05s faster than the original baseline. First prompt still pays the same agent
construction cost if it races the background/skeleton state, matching classic
CLI's deferred behavior.
Tests:
- python -m py_compile tui_gateway/server.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
This PR groups the TUI fixes that restore macOS Terminal usability and clean up the theme/composer regressions:
- copy transcript selections on macOS drag-release so Terminal.app users can copy while mouse tracking is enabled
- copy composer selections on macOS drag-release; composer selection is internal to TextInput and does not use the global Ink selection bus
- keep IDE Cmd+C forwarding setup macOS-only, and make keybinding conflict checks respect simple when-clause overlap/negation
- force truecolor before chalk initializes (unless NO_COLOR / FORCE_COLOR / HERMES_TUI_TRUECOLOR opt-outs apply) so the default banner keeps its gold/amber/bronze gradient in Terminal.app
- move TUI surfaces onto semantic theme tokens and preserve skin prompt symbols as bare tokens with renderer-owned spacing
- render focused placeholders as dim hint text in TTY mode instead of inverse/selected-looking synthetic cursor text
* feat(tui): auto copy-on-select for transcript text
Drag in the transcript already highlighted but you had to press Cmd+C to
land it on the clipboard, and the highlight cleared on copy — most users
never realised selection existed. Now drag-release fires copySelectionNoClear
so the text is on the clipboard immediately while the highlight stays put,
matching iTerm2's "Copy to pasteboard on selection" default. Esc clears.
Behaviour:
- Single click in the input still positions the cursor (TextInput onClick).
- Single click in the transcript still does nothing destructive.
- Double / triple click select word / line, then drag extends.
- /copyselect [on|off|toggle] (alias /cos) flips the setting at runtime,
HERMES_TUI_DISABLE_COPY_ON_SELECT=1 disables at startup, persists via
display.tui_copy_on_select in config.yaml.
Help overlay now lists drag-select, multi-click, and click-to-position
so the gestures are discoverable.
Made-with: Cursor
* fix(tui): support prompt text selection gestures
Add mouse drag selection and Shift+Arrow/Home/End extension inside the TUI composer so prompt text behaves like a normal editable field while keeping click-to-position and right-click paste intact.
Made-with: Cursor
* Revert "feat(tui): auto copy-on-select for transcript text"
This reverts commit 6701288fe0.
* fix(tui): allow composer selection from prompt whitespace
Give the composer a one-cell mouse capture pad before the editable text. The prompt glyph/gutter still does not become selectable, but dragging from the edge now anchors at input offset 0 so users do not need to hit the first character precisely.
Made-with: Cursor
* fix(tui): clear selections from blank composer space
Clicking blank space in the transcript or composer now clears active TUI/input selections like a normal text surface. TextInput clicks stop bubbling so cursor placement and selection gestures keep their local behavior.
Made-with: Cursor
* fix(tui): delegate prompt gutter drags to composer text
The prompt gutter is now an input gesture region, not selectable content. Dragging from the whitespace or prompt area anchors the composer selection at offset 0, while selection highlight/copy remains limited to actual input text.
Made-with: Cursor
* fix(tui): move composer cursor to end on selection clear
External clear actions now collapse the composer selection to the end of the input, matching normal text-field behavior after dismissing a selection.
Made-with: Cursor
* fix(tui): capture composer padding before prompt
Add an explicit mouse capture cell over the left padding before the prompt glyph. Drags starting there now delegate to the composer input at offset 0 instead of starting terminal-level selection over the prompt chrome.
Made-with: Cursor
* fix(tui): avoid npm install on lockfile mtime churn
Compare package-lock.json against npm's hidden node_modules lock by content instead of mtimes. Git checkouts and npm lock rewrites can make the root lockfile newer even when installed dependencies already match, causing hermes --tui to print Installing TUI dependencies on every launch.
Made-with: Cursor
* fix(tui): include prompt leading cell in gesture region
Use the prompt box's real layout region to cover the leading whitespace cell before the glyph. The cell now participates in mouse hit testing and delegates to composer selection instead of starting terminal-level selection.
Made-with: Cursor
* fix(tui): widen prompt-side gesture capture band
Capture a wider left-side band around the composer prompt row so drags starting in terminal gutter/padding cells are consumed and delegated to input selection, instead of triggering terminal-level selection chrome.
Made-with: Cursor
* fix(tui): make pre-prompt spacer non-selectable content
Replace the sticky-prompt fallback `Text(' ')` with an empty spacer box so the visual gap remains but no literal space character is rendered/copyable before the composer prompt.
Made-with: Cursor
* fix(tui): capture pre-prompt spacer without shifting prompt layout
Revert the widened negative-margin prompt capture band and instead capture drags on the dedicated spacer row above the prompt. This keeps prompt/text alignment stable while still delegating whitespace-start drags to composer selection.
Made-with: Cursor
* fix(tui): align prompt with status bar and capture full input row
Drop the leading prompt column from 3 to 2 so the input first character lines up with the status bar text. Wrap the prompt+input row in a single mouse-capture box and stop event propagation from TextInput's own handlers so any drag in that row delegates to composer selection without leaking to terminal-level selection.
Made-with: Cursor
* fix(tui): anchor hardware cursor during composer selection
When a composer selection covers a row exactly the column width, the rendered text fills the row and the terminal auto-wraps the hardware cursor to col 0 of the next row, leaving a ghost block beneath the prompt. Park the cursor at the start of the input box during selection so it can't escape the input region.
Made-with: Cursor
* fix(tui): hide hardware cursor during composer selection
Stop fighting auto-wrap by hiding the hardware cursor outright while the
composer has an active selection. This prevents both the ghost block under
the prompt (cursor wrapping past the last cell) and the parked-cursor block
on the first selected character. The cursor restores as soon as the
selection clears or focus changes.
Made-with: Cursor
* chore(tui): /clean — drop dead capture-pad path, dedupe gutter handlers
- TextInput: remove unused leftCaptureColumns prop and capture-pad math, drop
unused mouseApi.startAt, fold mouse offset into a single offsetAt helper,
share a MouseEventLite type across the four handlers.
- appLayout: hoist a GutterMouseEvent type and an endInputDrag callback so the
spacer/prompt/input rows share one shape.
- _tui_need_npm_install: lift the runtime-only key set to a module constant,
collapse nested isinstance checks, and document the mtime fallback.
Made-with: Cursor
* fix(tui): address copilot review on PR #16732
- Split InputSelection.clear() into clear() (cursor-preserving) and
collapseToEnd() (clear + jump to end). Cmd+C copy paths keep using
clear() so the cursor stays put; the blank-area click in useMainApp
switches to collapseToEnd() to match the requested UX.
- Spacer-row drags now force row=0 when forwarding into the input,
since the spacer's vertical origin doesn't align with the input box
and Ink mouse-capture keeps dispatching motion to the original
target. Prompt+input row drag keeps localRow because origins match.
Made-with: Cursor
* fix(tui): give TextInput Box an explicit width
After the /clean pass dropped the unused capture-pad math, the wrapping
Box also lost its explicit width and started sizing to its rendered
content. Clicks past the last character missed TextInput and fell
through to the parent prompt-row Box, which collapsed the cursor to
offset 0. Pin the Box back to `columns` so the input owns its full
column span regardless of value length.
Made-with: Cursor
* feat(tui): double-click select-all + hide cursor on terminal blur
- Track click time/offset in TextInput so a quick second click on the
same offset triggers select-all. Ink's screen-level multi-click is
bypassed once our onMouseDown captures, so the gesture has to be
detected locally.
- Extend the cursor-hide effect to also fire when the terminal loses
focus, so the hollow-rect ghost most terminals draw at the parked
cursor position disappears too.
Made-with: Cursor
* chore(tui): /clean — extract isMultiClickAt helper
Pull the click-recurrence math out of TextInput's onMouseDown into a
small isMultiClickAt(offset) helper so the handler reads as the gesture
list it actually is (multi-click → select-all, otherwise start).
Drop the redundant length>0 guard now that selectAll() already noops on
an empty value.
Made-with: Cursor
* docs(tui): explain _tui_need_npm_install content-vs-mtime comparison
Expand the docstring so future readers understand why we parse the
lockfiles instead of comparing mtimes, what the optional/peer skip
covers, how stale hidden-lock entries are handled, and when we fall
back to mtime.
TodoPanel now renders as a child of the most recent user message's
virtualized row container, so it visually belongs to that prompt and
follows it during scroll. Falls back gracefully when no user message
exists yet (panel just doesn't render).
CPU profile (Apr 2026, real-user scroll on 11k-line session) showed three
hot loops in the per-frame render path:
Output.get() per-frame walk: 24% total
└─ sliceAnsi(line, from, to) per write: 18% total
stringWidth(line) chain (cached + JS): 14% total
All three were re-doing identical work every frame: same string → same
clipped slice → same width.
Fixes:
1. Memoize stringWidth (8k-entry LRU) for non-ASCII strings; ASCII fast-path
skips the cache (inline scan beats Map.get for short ASCII, the >90%
case). String.charCodeAt scan up to 64 chars is cheaper than the regex
fallback.
2. Memoize wrapText (4k-entry LRU keyed by maxWidth|wrapType|text) — wrapAnsi
is pure and the same content reflows identically every frame.
3. Memoize sliceAnsi (4k-entry LRU keyed by start|end|str) for the
end-defined hot path used by Output.get().
4. Skip the slice entirely in Output.get() when the line already fits the
clip box (startsBefore=false && endsAfter=false). Most transcript lines
never exceed their container width, and tokenizing them just to slice
(line, 0, width) was pure overhead. This single fast-path drops
sliceAnsi from 18% → ~0% in the profile.
Also tighten virtualization constants (MAX_MOUNTED 260→120, OVERSCAN 40→20,
SLIDE_STEP 25→12) and cap historical-message render at 800 chars / 16
lines via HISTORY_RENDER_MAX_*; messages inside the FULL_RENDER_TAIL_ITEMS
window still render in full so reading-zone behavior is unchanged.
Validation, real-user CPU profile, page-up scroll on 11k-line session:
Output.get() self-time: 24% → 0.3%
sliceAnsi total: 18% → not in top 25
stringWidth family: 14% → ~3%
idle: 60.7% → 77.3%
Frame timings (synthetic page-up profile harness):
dur p95: ~10ms → 4.87ms
dur p99: 25ms+ → 12.80ms
yoga p99: ~20ms → 1.87ms
The remaining CPU in the profile is Yoga layoutNode + React commit,
which is the irreducible work for this UI tree size.
Adds a corner-overlay FPS readout gated on HERMES_TUI_FPS, fed by
ink's onFrame callback (so it's the REAL render rate, not a timer).
Displays fps, last-frame duration, and total frame count, colored by
threshold (green ≥50, yellow ≥30, red below).
Implementation:
* lib/fpsStore.ts — nanostore atom updated from a trackFrame()
sink. Ring buffer of last 30 frame timestamps; fps = 29/elapsed.
trackFrame is undefined when SHOW_FPS is off so ink's onFrame
short-circuits at the optional chain.
* components/fpsOverlay.tsx — tiny <Text> subscriber; returns null
when SHOW_FPS is off (React skips the subtree entirely).
* entry.tsx — composes onFrame from logFrameEvent (dev-perf) and
trackFrame (fps) so both flags can coexist. When both are off,
onFrame is undefined and ink never attaches the handler.
* appLayout.tsx — mounts the overlay as a flex-shrink=0 right-
aligned Box below the composer, conditional on SHOW_FPS.
Usage:
HERMES_TUI_FPS=1 hermes --tui
# bottom right: " 62.3fps · 0.8ms · #1234" (green/yellow/red)
Intended as a user-facing diagnostic during the scroll-perf tuning
pass — watch the counter drop while holding PageUp to see where
frames go silent, without having to run scripts/profile-tui.py in a
side terminal.
126 files post-compile with React Compiler; 352 tests still pass.
Adds a gate so we can A/B test whether bypassing the alt-screen +
viewport constraint lets the terminal's native scrollback beat our
virtualization on scroll perf.
Result: definitively NO. Inline mode is 40x worse on every metric
that moves, because AlternateScreen is what constrains the ScrollBox
to the viewport height. Without it, the ScrollBox grows to contain
every child of the transcript and every frame re-renders all 1100
messages.
Profile under hold-wheel_up (1106-msg session, 30Hz for 6s):

flickers 0 5 offscreen —
This is actually the cleanest data we've gotten so far:
* AlternateScreen is LOAD-BEARING for perf — its viewport height
constraint is what lets useVirtualHistory's culling work. No
constraint → ScrollBox grows unbounded → every fiber mounts.
* The outer terminal (Cursor's xterm.js) parsed 1.6 MB of ANSI in
under 10 seconds with drain p99 = 8.83 ms and 0 backpressure
frames. Our terminal-write hypothesis from last session was
wrong: the bottleneck is React + Yoga, not the wire.
* Doing proper inline mode (non-virtualized transcript in
scrollback, composer pinned below) is not a flag flip — it's a
different UI architecture. Leaving this flag in so anyone
re-running the experiment gets the same numbers, but not
building the architecture until we're sure the perf win is
worth the UX loss (it probably isn't — the fullscreen + virt
path is the one we should optimize, not replace).
Keeping the flag as an experiment gate. Flip HERMES_TUI_INLINE=1
and run scripts/profile-tui.py --compare to reproduce.
FloatingOverlays (SessionPicker, ModelPicker, SkillsHub, pager,
completions) was nested inside the !isBlocked guard in ComposerPane.
When any overlay opened, isBlocked became true, which removed the
entire composer box from the tree — including the overlay that was
trying to render. This made /resume with no args appear to do nothing
(the input line vanished and no picker appeared).
Since 99d859ce (feat: refactor by splitting up app and doing proper
state), isBlocked gated only the text input lines so that
approval/clarify prompts and pickers rendered above a hidden composer.
The regression happened in 408fc893 (fix(tui): tighten composer — status
sits directly above input, overlays anchor to input) when
FloatingOverlays was moved into the input row for anchoring but
accidentally kept inside the !isBlocked guard.
so here, we render FloatingOverlays outside the !isBlocked guard inside
the same position:relative Box, so overlays
stay visible even when text input is hidden. Only the actual input
buffer lines and TextInput are gated now.
Fixes: /resume, /history, /logs, /model, /skills, and completion
dropdowns when blocked overlays are active.
- appLayout.tsx: restore the 1-row placeholder when `showStickyPrompt`
is false. Dropping it saved a row but the composer height shifted by
one as the prompt appeared/disappeared, jumping the input vertically
on scroll.
- useInputHandlers: gateway.rpc (from useMainApp) already catches errors
with its own sys() message and resolves to null. The previous `.catch`
was dead code and on RPC failures the user saw both 'error: ...' (from
rpc) and 'failed to toggle yolo'. Drop the catch and gate 'failed to
toggle yolo' on a non-null response so null (= rpc already spoke)
stays silent.
- normalizeStatusBar collapses to one ternary expression
- /statusbar slash hoists the toggle value and flattens the branch tree
- shift-tab yolo comment reduced to one line
- cursorLayout/offsetFromPosition lose paragraph-length comments
- appLayout collapses the three {!overlay.agents && …} into one fragment
- StatusRule drops redundant flexShrink={0} (Yoga default)
- server.py uses a walrus + frozenset and trims the compat helper
Net -43 LoC. 237 vitest + 46 pytest green, layouts unchanged.
The 'columns' prop passed to TextInput was cols - pw, but the actual
render width is cols - pw - 2 (NoSelect's paddingX={1} on each side
subtracts two cols from the composer area). cursorLayout thought it
had two extra cols, so wrap-ansi wrapped at render col N while the
declared cursor sat at col N+2 on the same row. The render and the
declared cursor disagreed right at the wrap boundary — the last
letter of a sentence spanning two lines flickered in/out as each
keystroke flipped which cell the cursor claimed.
Also polish the /help hotkeys panel — the !cmd / {!cmd} placeholders
read as literal commands to type, so show them with angle-bracket
syntax and a concrete example (blitz row 5 sub-item 4).
Previous revision added marginTop={1} to the input which stacked as a
phantom gap BETWEEN status and input. The breathing row should sit
ABOVE the status-in-top cluster, not inside it.
- StatusRulePane at="top" now carries its own marginTop={1} so it
always has a one-row gap above (separating it from transcript or,
when queue is present, from the last queue item)
- Input Box marginTop flips: 0 in top mode (status is the separator),
1 in bottom/off mode (input itself caps the composer cluster)
- Net: status and input are tight together in 'top'; input and status
are tight together at the bottom in 'bottom'; one-row breathing room
above whichever element sits on top of the cluster
Three bugs rolled together, all in the composer area:
- StatusRule was measuring as 2 rows in Yoga due to a quirk with the
complex nested <Text wrap="truncate-end"> content. Lock the outer box
to height={1} so 'top' mode actually abuts the input instead of
leaving a phantom blank row between them
- FloatingOverlays (slash completions, /model picker, /resume, /skills
browser, pager) was anchored to the status box. In 'bottom' mode the
status box moved away, so overlays vanished. Move the overlays into
the input row (which is position:relative) so they always pop up
above the input regardless of status position
- Drop the <Text> </Text> fallback in the sticky-prompt slot (only
render a row when there's an actual sticky prompt to show) and
collapse the now-unused Box column wrapping the input. Saves two
rows of dead vertical space in the default layout
'top' and 'bottom' are positions relative to the input row, not the alt
screen viewport:
- top (default) → inline above the input, where the bar originally lived
(what 'on' used to mean)
- bottom → below the input, pinned to the last row
- off → hidden
Drops the literal top-of-screen placement; 'on' is kept as a backward-
compat alias that resolves to 'top' at both the config layer
(normalizeStatusBar, _coerce_statusbar) and the slash command.
