RT-191, chunk 4 of the headless git client: rt mission, a GitHub-Desktop-parity mission-control TUI in rt-ui.

What this adds

  • Protocol: mission:* intent vocabulary plus an optional payload field on the session Intent frame, golden-fixtured from both languages (session-open-mission.json, session-intent-mission-commit.json, session-model-mission.json — the model fixture is the TS↔Go handshake, reproduced by buildModel by construction and decoded by the Go view tests).
  • Go view (ui/internal/views/mission/): top bar with the adaptive action segment (GHD's exact state-machine order), changes pane with tri-state staging rows and commit box, chroma-highlighted diff pane with a stage gutter (all colors mapped to theme tokens), a generic modal engine for the repo/branch/worktree foldouts (headers, in-modal keybars, guarded rows), and full mouse routing (hover never moves the cursor; wheel, clicks, double-click, gutter previews).
  • TS driver (lib/mission/): git-actions.ts (headless deriveAction/runAction, argv-only spawns), model.ts (pure wire-model builder), driver.ts (the intent loop: staging via git-core DiffSelection with a compacted→absolute index translation, two-step discard confirm, guarded checkout, commit/amend/undo, daemon badge subscription).
  • Command: rt mission (tree leaf, registry thunk, non-TTY gates pinned in e2e).
  • Design contract: docs/design/mission/ boards (pencil source + PNG exports) with ratified terminal deviations in the README; the build was verified against the boards surface-by-surface with SGR token checks.
  • Compose test: a real MissionDriver + real git-core sandbox repo driven through select → line-stage → toggle-file → refusal → commit → undo, asserting on actual git state at each step.

Review process

Every task passed an implementer + reviewer gate; a whole-branch review then caught four compose-level seam breaks (wire notices unrendered, no path-selection intent, commit gating deadlock, inverted staging semantics) that the per-task gates structurally could not see — all fixed in the final wave with red-first tests, and the compose test now guards that seam class.

Known v1 limits (ticketed)

  • Line/hunk-level unstage is not supported (git-core has no reverse cached apply); attempts show a notice. Whole-file unstage works.
  • Remote name is assumed origin and pull.rebase is not read yet; publish-repository renders but is display-only.
  • History tab, stash restore, and context menus are deferred (render dimmed / notice).

canon() sorts JSON keys on both sides of the comparison, so it could not
catch Payload silently routed through map[string]interface{} instead of
staying json.RawMessage. Compare the fixture's raw payload bytes directly.

session.Run gains a trailing Options{Mouse bool}; mission is registered
in advertisedViews/viewFor and gets Mouse:true. Bubble Tea v2 has no
program-level mouse option (v1's WithMouseCellMotion moved onto
tea.View.MouseMode per frame), so Options.Mouse is wired through a
mouseView decorator (wireMouse) rather than a ProgramOption.

The mission view itself only decodes Current off the wire model per the
controller ruling for this task; the full wire shapes land in a later
task and replace Model wholesale.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Replace the skeleton Model (Current only) with the full wire shapes
(Badge, RepoRow, WorktreeRow, BranchRow, ChangeRow, DiffLine, DiffModel,
ActionModel, CommitModel, LastCommit) and add session-model-mission.json
as the cross-language golden fixture: 2 repos, 2 worktrees, 3 branches
(one guarded), 3 changes (all/none/partial), a 6-line diff with one hunk
line and selected add lines, a pull action, an undoable last commit, and
one stash.

SetModel now clamps the Changes cursor by path across a model swap
(board.go's selected-by-id precedent), and drops the unread raw field
flagged as dead state after Task 2.

Extends both protocol fixture suites (Go round-trip, TS typed parse) for
the new fixture.

Renders the four top-bar segments (repo, worktree, branch, action) as
pure functions over the mission Model: two-line label/value anatomy,
theme-role colors only, and the adaptive action segment's icon/pill
state machine from ActionStates.png. Branch segment covers normal and
detached states; checking-out lands with Task 8. zoneID threads
hover/open through renderTopBar now so later tasks only need to wire
real values instead of reshaping the call.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
render_test.go asserted glyph/pill text but no color, so a swapped
accent (push vs publish-branch share the up-arrow glyph) would have
passed silently. Add fgSGR-based color assertions per action Kind and
for the detached branch value, mirroring the picker view's SGR test
helper. Reword topbar.go's checking-out comment off an internal task
reference.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Adds the Changes sidebar (tabs, filter box, master row, tri-state rows,
stash strip), the commit box (summary/description textinputs, amend
banner, commit button, undo strip), and the bottom keybar to the
mission view, wired to a focus model (list, filter, diff, summary,
description) that routes keys and emits mission:stage/commit/undo/
action/select intents.

Per ruling R3, c only focuses the summary input; commit emits solely
via ctrl-enter from summary or description focus when CanCommit.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Amending banner now reads "a stops" (esc was never wired to amend and
stays that way); renderStashStrip's comment no longer cites a task
number; the ◪ mixed-state glyph is now theme.GlyphMixed instead of a
literal duplicated in two call sites.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Adds the diff pane to the mission view: a path/stats header, per-line
stage-bar and old/new number gutters, chroma-highlighted context/add
text (flat Coral for del, a fixed chroma-token-to-theme style table
so no non-theme hex reaches the terminal), binary/oversized/none
message states, and a board-tail-style scroll window with a 1-cell
Panel thumb. Diff-focused keys move the line cursor and emit
mission:stage (line/hunk) and mission:discard; the two-step discard
confirm stays in the TS driver.

Wires diff.go's cursor/scroll state and key handling into mission.go
(struct fields, SetModel's clamp call, and View()'s pane call), since
the diff pane replaces the prior placeholder there.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
space/s/d used to pass the cursor line's own SelIdx straight through,
which is -1 on a hunk header or context row -- and the cursor opens
on the fixture's hunk header, so this fired on the very first press.

space/d now resolve a mode+selIdx before emitting: an add/del line
stages/discards itself in line mode; a hunk header (the toggle for
its whole hunk) resolves to hunk mode and the first selectable line
after it; a context line has nothing to select and no-ops. s always
resolves within the cursor's hunk: its own line if selectable, else
the nearest selectable line forward then backward in the same hunk.
Neither key ever emits selIdx < 0 now; an unresolvable press is a
no-op rather than a malformed intent.

Zone-map-at-click-time hit-testing (mission.go's hitTest/sidebarHit/
diffHit/modalHitTest recompute the same pure layout each render already
used, rather than recording zones as a render side effect) routes
tea.MouseClickMsg/MouseMotionMsg/MouseWheelMsg through the mission view:
top-bar segments, tabs, file rows and their checkbox cells, the diff
pane's gutter/hunk/line targets, modal rows, and the commit box/undo
chip/stash strip.

Hover is a render hint only (HoverBg on rows, GutterHoverBar on the diff
gutter's stage-bar preview), never the keyboard cursor. Wheel moves
whichever pane's cursor the pointer sits over. A file row's second click
inside the window focuses the diff, mirroring the picker's own
double-click handling.

theme.go gains GutterHoverBar (Pink blended half-way toward Bg) via a new
blendToward helper ActionHighlight now shares.

Wires WorktreeRow through the real worktree:list/repos:status join
(joinWorktreeRows in model.ts, path-keyed against the badge feed the
driver already holds) instead of the single hardcoded current-worktree
stub. Notice now clears at the top of every intent dispatch so a stale
refusal or armed-discard prompt never survives an unrelated intent;
refusal paths still set it after the clear.

remoteName, pullRebase, and the per-branch guards map stay stubbed:
no dependency the driver already holds exposes "does this repo have a
remote at all" (distinct from per-branch upstream tracking), a
pull.rebase config reader, or a batch guard check across every branch
without an expensive per-branch checkBranchGuard call on every refresh.

renderUndoStrip's justify helper let a left string wider than its
available room (an oversized last-commit summary) push the composed
line past sidebarWidth, dragging the sidebar block wider on a narrow
terminal. justify now clips left to leave room for right before
joining them, so the short right-hand chip (Undo, or the keybar's
q quit) always survives intact and every composed line lands at
exactly the requested width.

mouseWheel picked the list vs. diff pane by X alone, so a wheel tick
over the keybar or notice row still nudged whichever cursor that X
range would normally own. It now bounds the tick to the body's Y
range first, mirroring hitTest's own bodyY check.

…k commit

The Go view now paints the wire model's Notice in the notice strip (wire
wins over a local refusal), emits mission:select {path} whenever the
Changes cursor lands on a different row (keys, wheel, and file-row click),
and gates commit on (wire canCommit OR local amend) AND a non-empty local
summary, clearing the drafts on emit. Wire canCommit now means only
'something is staged'; the driver refuses an empty-summary commit with a
notice and seeds selectedPath to the first change so the diff pane opens
populated. Local commit drafts and the amend toggle survive model pushes;
wire values only seed empty fields. Fixture canCommit follows by
construction (staged 2 > 0).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Per-file selections now seed from the file's actual staged state (fully
staged reads all-selected, anything with unstaged or untracked content
reads none-selected) instead of a blanket select-all. toggle-file goes
through whole-file git add / git reset -q HEAD (new commit-ops stagePath/
unstagePath wired as driver deps), which also covers binary and untracked
files and never hands stageSelection an empty selection. Line and hunk
presses stage exactly the pressed target; a toggle that would deselect is
an unstage the forward-only cached patch cannot express, so it refuses
with a notice. buildDiffModel answers Selected in git-core's absolute
numbering (unifiedDiffStart + in-hunk position) instead of the compacted
wire ordinal, activating the translation the selection map always needed;
the handshake test's selection input moves to absolute indices by
construction. The dead toggle-file discard branch is gone.

…-switch fixes

buildModel filters the visible changes list by case-insensitive substring
of the path while totals, the commit gate, and the placeholder keep
counting every change. A detached checkout sends HEAD's short sha as
current.branch (from the log entry the driver already fetches). An armed
discard confirm disarms on any non-discard intent, so a later d re-arms
with the prompt instead of executing against a stale target. currentBadge
falls back to the empty badge, never another worktree's. A repo switch
picks the target repo's first known worktree and refuses with a notice,
without half-switching, when it has none.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A real MissionDriver with real git-core against a mkdtemp sandbox (bare
remote, repo-local identity), fed the intent sequence a live Go view
emits: select a modified file, stage a single line, toggle-file an
untracked file, refuse a whitespace summary, commit, undo. Every step
asserts on the actual index and history (git diff --cached, show, log,
status --porcelain), the seam none of the per-side unit suites covered.

Merge Risk: 🟠 High · up to c99eb

The mission UI can target incorrect Git state or stage a different line under reachable conditions, while failed or stalled background operations may leave it unrecoverable. These issues should be fixed before merge.

52-70: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Compare the decoded model with the fixture payload.

The test decodes and re-encodes mission.Model, then compares the result with mission.Model. Both values have the same source. The assertion cannot detect field loss or key reordering during ModelMsg decoding.

Extract the fixture's raw model field independently. Compare its bytes with mission.Model.

Proposed fix
-	// Round-trip: the raw model bytes re-encode to the same JSON value the
-	// fixture carries, so ModelMsg never loses or reorders mission fields.
-	var roundTripped any
-	if err := json.Unmarshal(mission.Model, &roundTripped); err != nil {
-		t.Fatalf("mission model round-trip decode: %v", err)
-	}
-	reencoded, err := json.Marshal(roundTripped)

Inline comments:
In `@lib/mission/driver.ts`:
- Around line 368-369: Update the action flow around runAction and busyAction so
cleanup runs when runAction rejects: move the busyAction reset into a finally
block, then recompute and push the action state after cleanup. Preserve the
existing successful result handling and error propagation.
- Around line 299-301: Update the Git-status refresh around daemonQuery and
client.snapshot to capture currentRepo, currentWorktree, and selectedPath, then
fetch the snapshot and selected diff together. Apply rows, snapshot, and
stagingDiff only when those identifiers still match the active selection,
preventing stale results from being published after a worktree or path switch.
- Line 189: Update the git-status subscription callback around onGitStatus so
rejected promises are caught instead of becoming unhandled. On failure, set
state.notice to an error message using the Error message or String(err), then
call push() to report it to the session.

In `@lib/mission/git-actions.ts`:
- Around line 80-89: Update lib/mission/git-actions.ts lines 80-89 in spawnGit
to pass a child environment with Git repository-location variables removed
before Bun.spawn, while preserving the existing cwd and streams. Apply the same
environment scrubbing in lib/mission/__tests__/git-actions.test.ts lines 23-32
within runGit so temporary-repository commands use the requested directory.
- Around line 80-89: Update spawnGit to enforce a timeout while awaiting the Bun
process, terminate the child when the deadline is exceeded, and return a failed
ActionResult with timeout details. Preserve the existing stderr-based failure
result for processes that exit normally with a nonzero code, and ensure the
timeout path cannot leave the action pending.

In `@ui/fixtures/session-model-mission.json`:
- Line 13: Align the fixture’s meta value with the behind value: update the
metadata from “3 commits behind” to “2 commits behind” while preserving behind
as 2.

In `@ui/internal/views/mission/changes.go`:
- Around line 291-293: Update middleTruncate so every returned string respects
the display-width limit w: clip(s, w) when the rune-count guard would return the
original string, and measure the composed head/ellipsis/tail result with
lipgloss.Width before returning it, clipping that result when it exceeds w.

In `@ui/internal/views/mission/diff.go`:
- Around line 358-363: The hunk-header rendering in renderDiffLines must remain
exactly one terminal row by clipping the prefixed line text before applying the
width-constrained Lipgloss style. Update the line.Kind == "hunk" branch to pass
" " + line.Text through clip with width, preserving the existing background,
foreground, and rendering behavior.

In `@ui/internal/views/mission/topbar.go`:
- Around line 248-255: Update clip to return an empty string immediately when w
is non-positive, before invoking lipgloss width handling. Preserve the existing
truncation and rendering behavior for positive widths, including the

…dge/diff results, clear busyAction on failure

onGitStatus's promise rejected unhandled when refreshBadges threw, refreshBadges
applied a snapshot/diff for whichever worktree or selection was current by the
time its await resolved rather than the one it started with, and a rejected
runAction left busyAction stuck true. Catch and report the subscription
rejection, capture the worktree/selectedPath before the await and discard a
stale result, and reset busyAction in a finally.

spawnGit inherited the parent process env verbatim, so an exported GIT_DIR/
GIT_WORK_TREE/GIT_INDEX_FILE/GIT_OBJECT_DIRECTORY (a git hook, an unusual test
runner) would redirect fetch/pull/push at a repo other than cwd. Pass
git-core's scrubGitEnv() explicitly, and scrub the test file's own sandbox
runner the same way.

The golden fixture's action.meta read "3 commits behind" while behind was 2.
Corrected the fixture data and the TS handshake test's constructed ActionState
input so the fixture is still reproduced by construction.

… wide-rune paths

clip(s, 0) fell through to Render(s) because lipgloss v2.0.6's MaxWidth
no-ops on a non-positive budget, returning the full unclipped string instead
of empty. renderDiffLine's hunk-header branch passed its text straight to a
Width()-styled Render, which wraps rather than truncates non-inline content,
letting a long header spill onto a second row and desync diffHit's row
mapping. middleTruncate's head+tail guard counted runes, not display cells,
so a run of double-width (CJK) runes could pass the guard while still
overflowing the cell budget. Added an early return in clip, clipped the hunk
header to width first, and re-checked middleTruncate's composed result by
lipgloss.Width.

All eight review findings addressed on this head:

  • driver.ts:189 -- the git-status subscription's onGitStatus() call is now .catch()-guarded so a rejected refresh (a thrown daemonQuery/client.snapshot()) lands as a Notice instead of an unhandled rejection (3de0224).
  • driver.ts:301 -- refreshBadges() now captures the current worktree and selected path before its await, fetches the snapshot and selected diff together, and discards the whole result if either identifier no longer matches by the time it resolves, so a worktree switch or selection change mid-flight can no longer clobber the current state with a stale one (3de0224).
  • driver.ts:369 -- busyAction reset (and the recompute/push that follows) moved into a finally, so a rejected runAction no longer leaves the action model stuck busy (3de0224).
  • git-actions.ts:89 -- spawnGit now passes an explicit env: scrubGitEnv() (git-core's existing scrubber) so an inherited GIT_DIR/GIT_WORK_TREE/GIT_INDEX_FILE/GIT_OBJECT_DIRECTORY can no longer redirect a fetch/pull/push at a repo other than cwd; the test file's own sandbox runner does the same (775c41e).
  • ui/fixtures/session-model-mission.json:13 -- action.meta corrected from "3 commits behind" to "2 commits behind" to agree with behind: 2; the TS handshake test's constructed ActionState input was updated too, so the fixture is still reproduced by construction (1e550f0).
  • ui/internal/views/mission/diff.go:363 -- the hunk-header line is now clipped to width before rendering, since Lipgloss v2.0.6 wraps (rather than truncates) non-inline content at a fixed Width, and an unclipped header could otherwise spill onto a second row and desync diffHit's row-to-line mapping (d23d1ca).
  • ui/internal/views/mission/changes.go:293 -- middleTruncate now re-checks its result by lipgloss.Width and clips further if needed, since its rune-count guard could pass while a run of double-width (CJK) runes still overflowed the cell budget (d23d1ca).
  • ui/internal/views/mission/topbar.go:255 -- clip now returns "" immediately for a non-positive width, since Lipgloss's MaxWidth no-ops on <= 0 and previously fell through to render the full, unclipped string (d23d1ca).

Each fix has a dedicated test (RED-confirmed against the reverted code before the fix landed): lib/mission/__tests__/driver.test.ts, lib/mission/__tests__/git-actions.test.ts, lib/mission/__tests__/model.test.ts, ui/internal/views/mission/render_test.go.

Gates run clean: bun test lib/mission, bun test lib/ui, bunx tsc --noEmit, go vet ./..., go test ./..., bun run ui:build, and e2e/tests/mission.test.ts.
