Move the Go TUI from github.com/charmbracelet/{bubbletea,lipgloss} to the v2
ecosystem at charm.land/{bubbletea,lipgloss}/v2 (Go 1.25). v2's kitty keyboard
disambiguation is on by default, so Shift+Enter now reliably inserts a newline
in the composer (Ctrl+J / Alt+Enter kept as fallbacks for non-kitty terminals).
Approach: rather than rewrite ~190 key-match sites to v2's (Code, Mod) idiom, a
small shim (internal/app/key.go) converts a v2 KeyPressMsg into the v1-shaped
keyMsg the handlers already expect, at the single Update boundary. The rest is
mechanical:
- key constants tea.Key* → shim consts; tea.KeyMsg → keyMsg.
- lipgloss.Color is now a func returning color.Color, not a type → fields/params
retyped to image/color.Color (theme/diff/overlays/view).
- v2 View() returns tea.View: render() builds the string, View() wraps it and
carries AltScreen (alt-screen is a per-frame View field now, not a program opt).
- WithWhitespaceBackground/Foreground → WithWhitespaceStyle(Style).
- preview: drop lipgloss.SetColorProfile (v2 renders truecolor by default).
Build, vet, gofmt, and the full test suite are green; preview renders truecolor
across kinds.

Press d (or the "panel" palette command) in-session to cycle the right panel:
- events — the live event stream (default, unchanged)
- changes — a token-usage line (tokens + turns, summed from the transcript's
TurnMetrics) over a git-status-style list of files the session has
written, each with summed +/− from its diff. ^x still opens the full
diff.
- off — hide the panel; the output transcript takes the full width.
changesRows derives everything from data already in the model (router-turn
metrics + the tool entries' unified diffs), so no new protocol. Footer + ? help
updated; "changes" preview kind added.

Enter still submits; Ctrl+J (always) and Alt+Enter (most terminals) insert a
newline at the cursor. True Shift+Enter isn't distinguishable from Enter in
bubbletea v1.3.10 (terminals send the same byte, no kitty-protocol parsing), so
these are the working stand-ins — noted in the input hint.
- editorLines() renders the buffer as styled rows with the caret at the cursor,
splitting on \n and capping at maxInputLines (last rows kept). Both the idle
launcher input and the in-session bottom bar use it and grow to fit; View()
sizes the bottom bar via inputBarHeight() instead of the fixed inputH.
- Footer gains a "^J newline" hint in insert mode (non-filter); the launcher
sub-line shows "⌥↵/^J newline". New "compose" preview kind + editor_lines_test
(split + height cap).

The launcher removed the idle session list, so the per-row date moves to the R
resume overlay — now the sole session list. sessionListRow shows an absolute
local date (absDateISO → shortDateTime) alongside the relative age:
"Jun 22 14:30 · 5m ago", with the year shown for older-than-this-year rows.
Delete the now-unused idle-panel renderers (sessionRows / welcomeRows /
workflowRows) and renderMainNarrow's dead idle branch (renderLauncher owns idle,
narrow included). Add a "resume" preview kind to screenshot the R overlay.

Replace the idle two-panel layout (session list + welcome, where the welcome
panel duplicated the list) with an opencode-style launcher: a compact, centered
input whose lower-right shows the launch target and model (chat by default), a
hideable right rail of status + quick keys, and no session list — it's a keypress
away via R.
- Tab (or w) cycles the launch target: chat → workflows → chat (launcherWf),
shown at the input. Enter on chat starts a chat; on a workflow, StartSession
with the typed text as the brief.
- Right rail (connection, session/active counts, i/Tab/R/?/p keys) hides via the
new "rail" palette command. Drops automatically on narrow terminals.
- View() suppresses the bottom input bar on idle (the input is the launcher);
footer + ? help updated to the launcher keys (help-coverage test extended).
The old idle-panel renderers (sessionRows/welcomeRows/workflowRows) are now
unused but kept in the tree pending Phase 2 + a decision on where the session
dates should live now that the idle list is gone. Multi-line input (Ctrl+J /
Alt+Enter newline) is Phase 2.

Was the UTC-then-local time-of-day; now the same "Jan 02 15:04" / "Jan 02 2006"
shortDateTime as the session list, so a previous-day session isn't shown as if
it were today.

The collapsed tool row showed "tool output (N chars)" where N was len() of the
raw unified diff — i.e. the diff blob's *byte* length (headers, @@, +/-/context
all counted), labelled "chars". That number corresponded to nothing the operator
cares about, and len() is bytes not characters.
- Summarise a write/edit by the diff's row count instead — "· diff (7 rows) —
^x to view" — matching exactly what the ^x modal reports. Non-diff output (the
defensive fallback) now counts runes, not bytes, so "N chars" is truthful.
Retire itoaLen (the byte-count-as-"len" footgun).
- Harden the (+a −b) line counts in diffSummary: guard the file header with the
trailing space ("+++ "/"--- "), so a changed line whose content starts with
"++"/"--" is counted instead of mistaken for a header. Apply the same guard in
parseUnifiedDiff so such a line is rendered (and counted) rather than dropped.
tool_summary_test.go covers the diff-row summary, the rune (not byte) count, and
the ++/-- content-line edge case.

The idle "sessions" panel listed id/status/name/stage but no time at all. Add a
right-aligned last-activity timestamp (Session.LastEventAt) per row — "Jan 02
15:04" within the current year, "Jan 02 2006" for older — so old sessions are
distinguishable at a glance. The name is truncated first so the box's width
clamp never eats the date column. (The R resume overlay already shows a relative
age; this is the live list on the starting screen.)

The EVENTS panel showed "● live" off m.connected alone, so a completed/failed/
paused session kept reading "live" as long as the websocket was up — stale, since
a terminal session emits no more events. Derive the badge from the selected
session's Status (the same vocabulary the status bar uses): ✓ done, ✗ failed,
‖ paused, ● live while active, ○ idle when disconnected. event_badge_test.go
covers all five.

Three TUI-polish items.
- OUTPUT free-scroll: PgUp/PgDn (and ^u/^d half-page) scroll the transcript
back through history; esc snaps to tail-follow. outputScroll is clamped
against outputViewport(), which mirrors View/renderMain geometry, so the
edges land exactly (no dead presses unwinding an overshoot). routerRows
split into buildTranscriptRows (full render) + windowing so the handler
measures the same content. Tests cover the clamp + the fits-in-panel no-op.
- Help overlay: `?` (or the "help" palette command) opens a keybinding
cheat-sheet grouped by context (session / overlays / approval band) — the
non-palette keys especially. Any key dismisses it.
- Event-inspector filter: `/` filters the event list by a case-insensitive
substring of type/detail (currentEvents applies it); `c` clears, esc stops
editing then closes. Fresh per open. EVENTS side panel stays unfiltered.
go build / vet / test green; rendered help + filtered inspector via
cmd/preview (help, events-filter kinds).

Surface side-effecting ("external feedback") events in the conversation
flow, opencode-style, instead of only in the EVENTS side log.
- New RouterEntry role "action" (glyph + text) appended at arrival so it
interleaves with chat turns by order. Rendered dim with an accent gutter
glyph; the EVENTS panel still carries the full stream.
- Surfaced: tool start (⏵), tool done (✓ / ✎ wrote <path> (+a −b) for a
diff), tool failed (✗), rejected (✕ blocked), approval resolved
(⌘ approved / ✕ rejected, noting "· via grant" on a grant auto-approve),
and grant create/revoke (⊞ / ⊟ · scope). ApprovalResolved names no tool
on the wire, so the tool is recovered from the pending queue before the
gate is dropped.
- Toggle: "inline actions" palette command flips actionsHidden (rows are
always recorded, gated at render, so toggling reveals history); persisted
in tui-prefs.json. prefs.go refactored to load/mutate/save so the new
field and statusbarHidden no longer clobber each other.
- demo.go: "actions" preview kind.
go build / vet / test green; rendered the flow via cmd/preview.

Palette: each command now shows its bare-key shortcut in a key column (and the filter
matches on it), so the palette teaches the shortcuts instead of hiding them.
Status bar: a new "status bar" palette command opens a toggle overlay to show/hide the
non-essential segments (current stage, session status, workspace path, model, last-event
clock, resource gauge); correx/connection/session-name/spinner stay. Choices persist
TUI-local in tui-prefs.json (JSON in the config dir — display state, kept out of the
shared/replayed server config) and reload on launch.
Also trims the in-session footer (drops stats/model — both reachable via `p cmds`) so it
no longer overflows + truncates `q quit` at ~100 cols after the transcript-nav additions.
Tests cover toggle→render gating and prefs persistence; verified via cmd/preview renders.

Typing `@` at a word boundary in the chat input (mid-word `@` stays literal, e.g. emails)
opens a workspace file picker: it requests file.list for the session (cached per session),
filters as you type, and enter inserts `@path ` at the cursor — back to typing. Renders as
a transparent overlay, windowed around the selection. file.list is classified non-rendering
in the render-matrix guard. Tests cover token-boundary detection, ref insertion, and filtering.

ctrl+↑/↓ jumps between your sent (user) messages in the transcript: ctrl+↑ from the
bottom selects the most recent, steps to older ones (clamping); ctrl+↓ steps back and
drops to tail-follow past the last. The selected message is highlighted and scrolled
into view (routerRows tracks per-message row offsets and windows to the selection).
`y` yanks the selected message — or the latest turn when none is selected — to the
system clipboard over OSC52 (go-osc52, tmux-wrapped under $TMUX), which is SSH/Termius-
safe unlike a mouse drag. A brief "✓ copied" footer note animates out (and self-stops
the tick). esc drops the selection; switching sessions clears it. Tests cover the
user-message jump/clamp/tail and the copy-text selection.

Modals now composite over a dimmed copy of the screen behind them instead of an opaque
scrim, so the transcript stays faintly visible around a modal (opencode-style). center()
stashes the frame's base (View sets m.lastBase), strips+dims it to a faint scrim, and
splices the modal box over it (ANSI-aware via ansi.Truncate/TruncateLeft so the side
margins keep the dimmed content). An idempotence guard passes an already-full-screen
modal through unchanged, so the existing double-center builders don't get re-dimmed.
Geometry tests assert the composite still fills the screen exactly.

Typing `/` as the first char of a chat line opens the command palette inline
(opencode-style), instead of typing a literal slash; mid-line `/` stays literal.
Factors openPalette() (shared with the `p` key) and advertises `/ cmds` in the
insert-mode footer when the line is empty.

R opens a navigable overlay of recent sessions (GET /sessions: short id, status,
workflow/stage, relative age); enter resumes via POST /sessions/{id}/resume, which
replays onto the existing global /stream (no WS re-dial). Fetch/resume errors surface
in the overlay, never panic. stdlib-only (ws.Client.HTTPBase derives the base URL).

renderMarkdown wraps charmbracelet/glamour (dark style, per-width memoized) and is
hooked into the router chat-turn render path; falls back to plain content on any
glamour error so the TUI never crashes or loses text. Other roles/UI untouched.

Render a workflow.proposed frame as a single-select picker with a manual-answer
slot: ↑↓/jk to choose, enter to launch, e for custom, esc to peek away. Picking
a candidate sends StartSession (and focuses the launched session); the custom
slot continues the conversation via ChatInput. Reuses the modal helpers from the
clarification view.
Render stage clarification questions as an AskUserQuestion-style form:
header chip, prompt, selectable option chips, and a free-text custom slot.
Arrow/hjkl nav, space to select, e for custom, enter to submit. Submit
guards on all-answered and sends ClarificationResponse; the parked stage
re-runs with the answers in context.
The TUI overflowed and became unreadable on narrow terminals: the status bar and
footer spilled far past the edge (justify never truncated), the two-column main
split shrank the events panel to ~20 cols, and the stats overlay wrapped mid-word.
- justify is now width-safe: shrinks the left segment first (the right holds the
high-signal connection clock / active spinner), clamps the right only as a last
resort, ANSI-aware so it never slices escape codes. No line can exceed the width.
- Main area collapses below narrowWidth (96): single full-width session list when
idle; output stacked over the live event strip in-session (the strip is too
valuable to drop — the constraint is width, not height).
- Compact chrome when slim: status drops workspace/gauge/provider-suffix and uses a
short clock ("◷ 3s") + bare spinner; footer uses a reduced hint set and drops the
"Soft·blue" badge; approval action row tightens its gaps so decision keys stay
visible.
- Overlays get near-full-width on slim terminals; stats pane uses compact formats +
per-line clipping so it never wraps.
Tests: no rendered line exceeds the terminal width at 40–160 cols (incl. the stats
overlay); narrow in-session main stacks output+events.
Implements the load-bearing TUI-requirements §2 hard requirements:
- Last-event clock: "last event Ns ago" always visible in the status bar while
in-session, updating every frame tick. Turns warn-colored when an active session
has gone quiet past the stale threshold — the "thinking vs hung" tell. The
WebSocket connection indicator (●/◌/○) already covers immediate drop visibility.
- Unknown-event raw fallback: applyServer now surfaces any unrecognized,
session-scoped event type as a raw row in the event stream instead of silently
dropping it (the frontend must not lie by omission). Recognized-but-unrendered
types (router.response, protocol_error) get an explicit no-op so the default
branch means genuinely unknown.
Tests: agoLabel formatting, unknown-event surfaces-as-row, known-ignored
no-spurious-row. Preview "session" frame exercises the clock.
Deferred: the full Go↔Kotlin per-event-type render matrix (§2 last bullet) — a
larger fixture effort than the core behaviors landed here.
A multi-line paste put raw newlines into the single-line input slot, overflowing
the fixed-height box and leaving a smeared/stale region. flattenForDisplay collapses
newlines (↵) and tabs for rendering only; the inputBuffer keeps real characters for
submission.
- generic SystemResourceProbe: owner-agnostic /proc/meminfo system RAM
overlaid on the vendor GPU probe, wired on both managed and static paths
so the VRAM/GPU/RAM gauge renders with an external llama-server (was dormant)
- F-002: classify provider 4xx (e.g. llama.cpp 400) as terminal, not retryable
(except 408/429); stops retrying deterministic request failures to exhaustion
- F-003: FileSystemPromptLoader expands leading ~ / ~/ to user home
- F-004: map InferenceFailedEvent + RetryAttemptedEvent to new
ServerMessage.InferenceFailed / RetryAttempted, decoded+rendered in tui-go;
ArtifactContentStoredEvent explicitly mapped to null (internal, no warn)
- tests: tilde expansion, SystemResourceProbe (static/managed/fail-soft)
Add TypeRouterNarration constant, mark it event-bearing, decode golden test,
applyServer case appending RouterEntry{Role:"narration_llm"} with metrics, and
routerRows render branch showing bright ◆ prefix with FgStrong content + metrics suffix.
Stage started/completed/failed events are now injected into the router
transcript (role "stage") and rendered in Faint colour, giving the
operator a chronological in-feed view of workflow progress alongside
user/router/tool turns.
SessionWorkspaceBoundEvent already recorded the bound workspace root but
it was never surfaced. Map it to a new session.workspace_bound frame
(sealed ServerMessage variant, auto-registered; re-emitted on reconnect
via the snapshot replay), carry it on Session.WorkspaceRoot, and show it
home-abbreviated in the status bar (⌂ ~/Programs/correx). Golden test
pins the decode.
- Events were hard-capped to the last 7 per session in addEvent, so the
e-inspector and EVENTS panel could never show more. Raise to 1000
(effectively all, bounded); the EVENTS panel now shows the latest that
fit (tail), and the inspector scrolls a window around the selection
with a position indicator.
- The TUI had no approval.resolved handling at all — the decision frame
was ignored and pending only cleared on session.resumed. Add the
constant + case: clear the gate and record an ApprovalResolved event
(APPROVED/REJECTED/AUTO_APPROVED + reason) into the stream.
- Status bar now shows the current stage and session status alongside the
name. Relabel the cryptic "N bg" badge to "N elsewhere".
Three QA-found issues in the approval gate:
- displayState gated the in-session/approval surfaces on hasApproval
before sessionEntered, so moving the list cursor onto a session with a
pending gate auto-opened it, and `l` back-to-list couldn't escape
(the gate re-popped). Require sessionEntered first.
- The band ran every preview through the two-column diff renderer, so a
shell tool's argv JSON rendered as an identical-column "diff". Detect
real unified diffs (isUnifiedDiff); render other previews as plain
text, and drop the ^x fullscreen hint when there's nothing to expand.
- The footer duplicated the band's approve/reject/steer/diff keys. It now
shows navigation (l back / e events / q quit) instead.
Replace the floating approval modal (which blanked the whole UI) with an
opencode-style band that takes the input bar's slot while a gate is
pending: tool/tier/risk header above a side-by-side old|new diff, with
the session output and event stream still visible above it. The band
height adapts to the diff length.
Add a unified-diff parser that aligns removals/additions into split rows
(blank left cell for a create, blank right for a delete) and a
two-column renderer shared by the band preview and the ^x fullscreen
view. Wire plain a/r to approve/reject to match the advertised keys.
- gate session-list nav on idle so in-session arrows/jk don't move the list (5a)
- approval dismiss on esc + in-session 'a' reopens a pending approval (5b)
- auto-focus a newly started workflow session (was running invisibly)
- approval actions on Ctrl chords (^a/^r/^x) matching the modal; bare/Alt letters no longer approve; diff closes on ^x/esc
- steer hint in the approval modal; session UUID in the input bar
- env-gated debug logging (CORREX_TUI_LOG) with k.Alt in the key trace
Go TUI decodes model.changed / model.list / resource.status and renders a
status-bar VRAM/GPU%/RAM gauge plus a models overlay (m key / palette 'models'):
lists configured models with the resident one marked, enter swaps (SwapModel),
c clears the pin (ClearModelPin). All three new server messages are
non-event-bearing control/gauge frames, applied immediately like
provider.status_changed.
Server addition required for the picker: ServerMessage.ModelList (model.list,
NonEventMessage) sent once in the initial snapshot from
ManagedInferenceRouter.availableModelIds()/currentModelId() — the TUI otherwise
cannot enumerate swap targets.
Completes the 5-slice model-lifecycle feature. ./gradlew check green; go build/vet clean.
