Closes the gap between the shipped rt mission view and the design boards, found on first live run: the build matched the boards' structure and tokens but not their composition.

What changed

  • Surfaces: the top bar and keybar paint their BgSubtle bands; every composed row carries an explicit background; and the view sets the terminal background (OSC 11) to the theme Bg so erased and never-drawn cells resolve to the canvas color instead of the terminal default. Verified through a real-renderer replay (charm vt emulator + ultraviolet compositing), not just composed-output byte scans; a whole-frame loop test now asserts per-cell background coverage for both the populated and empty states.
  • Segment icons: the repo/worktree/branch segments wear Nerd Font octicons (repo U+F401, repo-forked U+F402, git-branch U+F418), ratified with the owner; the checkbox-state circle family is unchanged.
  • Bottom-docked commit block: the stash strip, commit box, and undo strip pin to the sidebar's bottom edge with flexible fill above, per Main.png and the new EmptyState.png; mouse hit-zones are height-derived and the tests compute rows from the same layout function.
  • Empty state: a clean worktree renders the boarded "No local changes" card (title, subline, key hints) instead of a lone "select a file" line. The board (EmptyState.png) is new and committed with this change.
  • The parity checklist: the design README now carries the per-board feature walk (surfaces, composition, iconography, tokens, states) that binds every future visual pass; the original pass missed composition-level features by skipping straight to row content and token colors.

Six distinct background-fill leaks were found and fixed along the way (trailing chevrons, pill separators, border backgrounds, ANSI-aware clipping, chroma token backgrounds, JoinVertical padding), each with a red-first test.

The top bar, keybar, sidebar rows, and diff pane relied on the terminal's
own default background showing through everywhere except cursor/hover
rows, the hunk row, the diff header, and the commit button. Every row's
shared style variable now carries its own background (BgSubtle for the
top bar and keybar bands, Bg for sidebar/diff body rows), with hover
(HoverBg), open (Surface), cursor (SelBg), and the hunk/header fills
still overriding it exactly as before.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The top bar's repo/worktree/branch segments led with checkbox-state
glyphs (◪/◉/●, and ○ for detached). They now wear the ratified Nerd
Font octicons (theme.GlyphRepo/GlyphWorktree/GlyphBranch), with the
detached state keeping its Peach treatment but dropping the old
●/○ circle swap in favor of the same branch glyph. The action
segment's own state-driven glyph and the checkbox/master-row circle
family elsewhere are untouched.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The stash strip, rule, commit box, and undo strip stacked directly
under the changes list, so a short or empty list left them floating
high with dead rows beneath -- Main.png and EmptyState.png both pin
them to the sidebar's bottom edge instead.

renderSidebar now composes a top block (tabs, filter, master row,
changes list) and a docked block (stash/rule/commit box/undo) with a
Bg-filled gap sized to whatever room the pane has left; the gap
shrinks to zero once the two blocks' natural height already meets or
exceeds the pane, so the changes list overflowing never pushes the
docked block off. layout() exposes the same top/docked/filler heights
sidebarHit now uses to offset the docked rows, since their y depends
on pane height rather than row count.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A clean worktree showed the same lone "select a file" line the diff
pane uses before any row is selected, with no acknowledgment that
there is nothing to select. docs/design/mission/EmptyState.png pins a
centered card instead: a bold title, a dimmer subline, and the four
keys that get a repo out of the clean state (fetch/pull/push, branch,
worktree, repository).

renderDiffPane now takes this path only when Changes is empty; a
changes list that simply hasn't had a row selected yet -- the state
before the driver's own seed lands -- still shows the plain hint.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Spot-row SGR checks missed several holes a cell-by-cell scan of a
real capture caught: a top-bar segment's trailing chevron rendered
through the bare fg() helper (no background at all); the action
segment's pill separator was a plain unstyled space; the filter and
commit-box borders set BorderForeground but never BorderBackground,
so the border glyphs themselves stayed unpainted; clip()'s appended
ellipsis is bare text, which is fine when the caller feeds it plain
text that a later Render call colors, but justify() and the modal's
own keybar feed it an already-styled ANSI string, so a long undo-strip
summary or keybar left the ellipsis on the terminal's own default;
chroma's highlightLine painted each token's foreground only; and the
empty-state card's lipgloss.JoinVertical(Center, ...) pads shorter
lines with bare unstyled spaces of its own.

Added bgCoverage/assertFullyBgFilled and two whole-frame tests
(populated fixture, empty state) that walk every rendered line's SGR
state and fail on the first cell with no explicit background --  the
loop a spot check can't fake passing.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Cell-level Bg/BgSubtle fills (this branch's earlier commits) can't win
against two things a real terminal does that an in-process render test
never sees: bubbletea's renderer is free to erase a run of styled
trailing blanks down to a bare erase-to-end-of-line control code
(painting with the terminal's OWN default background, not whatever SGR
the erased content carried), and any region genuinely outside what the
app drew -- an oversized real pane, scrollback -- was never touched at
all. Only a terminal-level default (OSC 11) reaches either case.

mission.go's View() now sets tea.View.BackgroundColor to theme.Bg on
every frame alongside the existing AltScreen flag. Kept the per-row
Bg/BgSubtle plumbing from the previous commit as-is rather than
simplifying it: live verification (below) reproduced the
"region beyond the composed frame" failure mode this fix addresses,
but did not reproduce an erase-to-EOL hole in the cases it already
covered, so there wasn't clean evidence that removing any of it was
safe.

Verification went through the real compiled binary over a real pty
(testutil.Session, the same shape the existing mouse tests already
use), not just Mission.View().Content: testutil/screen.go gained
CellBackground/CellBackgroundBeyondPTY/TerminalBackground, which replay
the session's raw tty bytes through a real terminal emulator
(charmbracelet/x/vt) and charmbracelet/ultraviolet's own Draw/Screen
compositing -- the same resolution order (explicit cell style, else the
terminal's own registered default) a real terminal applies, which a
plain ANSI-byte scan of the tty stream can't reproduce for an erased or
never-drawn cell. Three new tests in mission_test.go confirm, with the
fix reverted, that (a) the terminal's own registered default background
is NOT theme.Bg and (b) a cell in a region entirely outside the pty's
own 30 rows is unset entirely; with the fix, both resolve to theme.Bg.

📝 Walkthrough

Walkthrough

The command is renamed from rt mission to rt glitter. Mission UI rendering now uses fixed geometry, shared scrolling primitives, explicit theme backgrounds, Nerd Font glyphs, full-height foldouts, branch metadata, and expanded terminal and interaction tests.

Changes

Mission UI parity

Layer / File(s) Summary
UI contracts and shared primitives
docs/design/mission/README.md, ui/go.mod, ui/internal/testutil/screen.go, ui/internal/theme/theme.go, ui/internal/views/picker/*, CLAUDE.md
Design rules, terminal inspection helpers, theme glyphs, shared scrollbar APIs, and reuse guidance were added or updated.
Branch grouping and metadata
lib/relative-time.ts, lib/git-ops.ts, lib/mission/*, lib/ui/protocol.ts, ui/fixtures/session-model-mission.json, ui/internal/views/mission/model.go
Branch rows now identify default branches, group recent and guarded branches, and display relative dates. Default-branch resolution is cached per worktree.
Theme-backed surface rendering
ui/internal/views/mission/changes.go, ui/internal/views/mission/diff.go, ui/internal/views/mission/highlight.go, ui/internal/views/mission/modal.go, ui/internal/views/mission/topbar.go
Mission surfaces, diff rows, highlighted tokens, modal badges, top-bar segments, keybars, and clipped content now preserve configured backgrounds and themed glyphs.
Sidebar layout and foldout scrolling
ui/internal/views/mission/mission.go, ui/internal/views/mission/modal.go
The sidebar and foldouts now use fixed geometry, bounded scrolling, bottom-docked controls, filler rows, pinned keybars, and shared hit-test coordinates.
UI rendering and interaction validation
ui/internal/views/mission/*_test.go
Tests cover backgrounds, empty states, branch metadata, modal sizing, scrolling, docking, hit zones, icons, clipping, ANSI output, and complete frame coverage.

Glitter command rename

Layer / File(s) Summary
Command registration and behavior
commands/glitter.ts, lib/command-tree-def.ts, lib/module-registry.ts
The top-level command and lazy loader now use glitter, and the interactive-terminal error names rt glitter.
Command documentation and end-to-end coverage
e2e/tests/glitter.test.ts, website/docs/reference/glitter.mdx, website/docs/reference/mission.mdx
End-to-end tests and reference documentation now use rt glitter; the rt mission page was removed.

CodeRabbit review on PR rt#353, all three verified against current
code and valid:

- renderDiffPane gated the clean-worktree card on len(m.model.Changes),
  which is the FILTERED list (lib/mission/model.ts computes
  changedTotal from allChanges before the filter narrows it). A filter
  matching nothing on a dirty worktree read as "No local changes".
  Gate on m.model.ChangedTotal instead.
- renderEmptyStateCard pre-padded every line to its own natural widest
  line before applying the pane's own width. A pane narrower than the
  longest hint line left lipgloss to wrap it instead of truncating,
  growing the block past height. Cap maxW at width and clip each
  styled line with clipOn before padding.
- The detached-branch glyph test's Peach check was a bare
  Contains(out, fgSGR(Peach)), which the detached VALUE text ("On
  <sha>") also wears -- it could pass even if the icon itself lost its
  own Peach foreground. Added sgrImmediatelyBefore to anchor the check
  to the glyph's own adjacent SGR run; confirmed it actually catches
  the regression a bare Contains missed (verified by temporarily
  breaking the icon's color and watching the new assertion fail, the
  old one pass).

Addressed all three Minor findings from the CodeRabbit review in 71b756a:

  1. diff.go:207 (empty card gated on the filtered list) — valid. Verified lib/mission/model.ts computes changedTotal from allChanges before the filter narrows changes, so len(m.model.Changes) == 0 could read a filtered-to-nothing dirty worktree as clean. Gated on m.model.ChangedTotal instead.
  2. diff.go:279 (renderEmptyStateCard can wrap and grow past height) — valid. maxW is now capped at width and each line goes through clipOn before padding, so a pane narrower than the longest hint line truncates instead of wrapping.
  3. render_test.go:1314 (Peach check not anchored to the glyph) — valid. The detached branch's value text also wears Peach, so the old Contains(out, fgSGR(Peach)) could pass even if the icon lost its own color. Added sgrImmediatelyBefore to check the SGR run adjacent to the glyph itself; confirmed by temporarily breaking the icon's color that the new assertion fails where the old one passed.

All three came with new/updated tests (TDD: confirmed RED against pre-fix code, then GREEN). Gates: go vet ./..., go test ./... (all packages), bun run ui:build all green.

The build's quantization silently dropped every sub-cell padding
measurement from the design source (26px/row cell unit), cramping the
top bar, removing the tabs/filter breathing gap, and collapsing the
commit button to a single thin row. Implements the ratified row spec:

- Top bar: 3 rows per segment (label, value, a blank BgSubtle band row
  for the board's own bottom breathing), hover/open covering the full
  span.
- Sidebar top: one blank Bg row between the tabs underline and the
  filter box (the board's rule+gap).
- Commit box: one blank Bg row between the rule (or amend banner) and
  the summary box (the board's own top padding).
- Commit button: 3 rows -- fill, centered label, fill -- all full
  sidebar width, Pink/Panel, never a single thin row.

sidebarHit's row offsets and every y-dependent mouse/zone test now
follow these through m.layout() (a new commitButtonY/changesRowY/
filterRowY helper set) rather than hardcoded absolute rows, so the next
geometry change won't silently desync click targets from what renders.
Added a battery of layout()-derived geometry tests pinning each item of
the row spec, at both the isolated render-function level and the full
composed frame; both whole-frame background-coverage loop tests
(populated + empty state) re-confirmed green against the new geometry.

The parity checklist's Composition item names docking and stretching
but had no written contract for the vertical-rhythm quantization
itself -- the 26px/row cell unit, and the ruling for every board
measurement that isn't a clean division. Adds a Terminal geometry
table (board element, px, cells, terminal rows, ruling) to the mission
README, the same kind of binding reference theme.go already is for
tokens.

Changes and History each occupy half the sidebar width with centered
labels, per Main.png/EmptyState.png; the underline runs the full
width, Pink under the active tab's half and theme.Rule under the
inactive half (the board's own bottom border). tabsHit's click zones
follow the same half-width split -- the left half is inert (Changes is
already active), the right half resolves to History.

The 3-row fill/label/fill button (board h=32px against the 26px row
unit) overshot: quantized on its own it's 1 row, not 3. Back to a
single filled, centered-label row. The blank Bg row that separated it
from the description box is new -- the summary/description seam stays
flush, but this one is now an explicit gap (owner's round-2 ruling) --
so the net footprint is unchanged at the sidebar level even though the
button itself shrank. sidebarHit's offsets and the geometry tests
follow; docs/design/mission/README.md's Terminal geometry table and
its sidebarBlocks net-effect note are updated in the same commit.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Each foldout's width is max(its anchor segment's own column span,
its content's natural width). The repo segment spans the whole
sidebar, so the repo modal now renders exactly sidebarWidth wide,
anchored at x=0 -- the same width as the repo button. Branch and
worktree modals gain the same floor (their own segment's width) but
keep growing for content past it, and still clamp to the frame as
before.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The user-facing verb is renamed from "rt mission" to "rt glitter" --
CLI surface only. Internal naming is unchanged by design (protocol,
not user-visible, and renaming it would be a large coordinated fixture
churn for no user-visible gain): the Go package
ui/internal/views/mission, the rt-ui view kind ("session --view
mission"), the mission:* intent namespace, lib/mission/, the
ui/fixtures/session-*-mission.json fixtures, and docs/design/mission/
all keep their names.

lib/command-tree-def.ts's leaf key becomes glitter (module/fn to
match); commands/mission.ts -> commands/glitter.ts (git mv,
missionCommand -> glitterCommand); lib/module-registry.ts's thunk
entry updated and kept alphabetical; the interactive() gate line reads
"rt glitter needs an interactive terminal (it drives a live board from
the one you are in)"; e2e/tests/mission.test.ts -> glitter.test.ts
(git mv) with both pinned gate strings updated. Regenerated docs:
website/docs/reference/mission.mdx removed, glitter.mdx committed.

rt resolves subcommand names exactly (no prefix matching), so glitter
does not collide with git; no alias added.

Standing constraint (build shared components, never parallel
implementations): exported picker's own Viewport/ThumbSpan/ThumbCell
(picker/scroll.go) -- vim-style scrolloff, a caller cap, and the same
h*h/n thumb-sizing math the diff pane had duplicated byte-for-byte.
ThumbCell now takes its thumb/rest styles as parameters so each view's
own background still applies; picker's own render loop migrated to
the exported names with zero behavior change (its own full suite is
green).

mission/diff.go's renderDiffLines now calls picker.Viewport/ThumbSpan/
ThumbCell instead of its own diffViewport/diffThumbSpan/diffThumbCell
(deleted): same "no cap, fill the pane" contract, plus scrolloff for
free.

The Changes list gets real scrolling for the first time: previously a
list longer than the sidebar's flexible middle space just grew the
whole frame past the terminal's own height, with nothing to reach the
rest. mission.go's sidebarBlocks/layout() split changes: the top
section is now a constant 7 rows (tabs/gap/filter/master) plus a
FIXED-HEIGHT list region sized to whatever the top rows and docked
block don't claim -- renderChangesList windows it through the same
picker.Viewport/ThumbSpan/ThumbCell, cursor-follow and a Panel thumb
included. sidebarHit's row math and every layout-derived test follow.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Every foldout (repo, branch, worktree) now spans the full frame
height, GitHub Desktop's own real behavior: its top edge sits on the
anchor row below the top bar as before, but its bottom edge is always
the frame's own last row -- covering the main keybar for as long as
it's open, which GHD also does and which is intended, not a bug.

modalBoxLines now takes the box's target inner height and lays out a
FIXED-height scrollable row region (modalDisplayLines flattens matches
and their group headers into one sequence so the viewport windows over
real display lines rather than re-deriving header placement inside
whatever slice is visible; modalRowViewport resolves it through the
shared picker.Viewport) followed by the pinned bottom block (the
action row when the kind has one, the closing rule, the keybar) --
exactly the sidebar's own fixed-top/flexible-filler/pinned-bottom
pattern. A short list top-aligns with Surface filler below it; a list
long enough to scroll (owner's explicit reinforcement: this must hold
for all three foldouts, not just branch, with real repos carrying
hundreds of branches) gets a Panel thumb via the same picker.ThumbSpan/
ThumbCell the diff pane and Changes list already share. modalHitTest
follows the same fixed geometry.

Fixed a real hole the new whole-frame bg-coverage-with-modal-open test
caught: modalRowLine's badge (dirty-file dot, ahead/behind pills, the
clean check) was pre-rendered at modal-construction time via a bare
fg()-only helper, before the row's own cursor/hover background was
known. renderBadge/renderAheadBehind now take the row's own bg style
and render at paint time instead, matching every other fragment in
this file.

docs/design/mission/README.md's ratified-deviations section records
the full-height behavior superseding the boards' content-height
foldout drawings. CLAUDE.md's rt-ui section gets a short "shared
primitives" note (Viewport/ThumbSpan/ThumbCell, clip/clipOn) per the
owner's standing constraint against parallel implementations.

🟡 Minor · Clip overlong commit labels before rendering. · changes.go:242

ui/internal/views/mission/changes.go:242
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clip overlong commit labels before rendering. A long branch makes the non-amend Commit.ButtonLabel wider than the 46-cell sidebar. Lipgloss wraps that label into multiple rows. The docked block remains bottom-pinned, but sidebarHit treats only the first button row as hitCommitButton; when an undo strip exists, the second button row can trigger hitUndoChip, while the actual undo row is not clickable. Use the existing clip helper to preserve the button's one-row geometry.

Wire-shape change ahead of the Go rendering: MissionBranchRow gains
"default" (bool: this row is the repo's remote default branch,
origin/main or origin/master stripped of its remote prefix) and
"when" (driver-computed relative date, GHD-style -- "2 days ago",
"last month" -- empty for the current row, which shows its ahead/
behind pills in that slot instead). group's union gains "default
branch" alongside the existing recent/other/guarded.

git-core's BranchInfo already carries committedAt via for-each-ref's
own --format argv (refs.ts); no git-core change was needed. The new
lib/relative-time.ts formatter is its own small module rather than a
third variant of lib/tui/utils/label.ts's compact timeAgo or
lib/mission/git-actions.ts's days-only formatFetchMeta, neither of
which produces GHD's long-form week/month/year buckets.

buildBranchRows (model.ts) computes sections for the WHOLE branch
list at once, not per-row: the default branch's own section, the
RECENT_BRANCH_COUNT=5 freshest branches by commit date EXCLUDING the
default and current (so neither displaces a genuinely different
recent branch), guarded unchanged, everything else falls to "other".
buildModel takes an injected `now` (defaults to the real clock) so
its own golden-fixture test stays deterministic without mocking time
globally. driver.ts threads getRemoteDefaultBranch's existing
(already used by the checkout guard) result through as the new
defaultBranch input.

Coordinated by construction: lib/ui/protocol.ts's MissionBranchRow,
ui/internal/views/mission/model.go's BranchRow, the golden fixture
(ui/fixtures/session-model-mission.json), and both languages' fixture
tests (lib/ui/__tests__/protocol.test.ts, model_test.go) all updated
together, mirroring the existing wire-field precedent.

Wire the branch dropdown's Go rendering to the sections and dates
lib/mission/model.ts (buildBranchRows) already computes on the wire:
newBranchModal only keeps ahead/behind pills for the current row now,
every other row carries its own relative date (when) in that same
badge slot, and a guarded row still wins with the lock glyph over a
date on the wire. modalWidth's row-width measurement follows the same
priority (guarded > when > badgeData) so a date no longer measures as
an empty badge. modalGroupHeaderText already rendered "default branch"
verbatim (it just returns the group string), so no header change was
needed there.

Updated the shared render_test.go fixture (modalFixtureModel) and the
group-header test to the real default-branch/other/guarded taxonomy
buildBranchRows now produces, and added coverage for: a non-current
row showing its date instead of pills, the current row keeping its
pills, and a guarded row keeping its lock glyph despite having a date
on the wire.

Out of scope per the owner's ruling: GitHub Desktop's Pull Requests
tab and its merge-into footer action (the existing New Branch action
row already covers branch creation).

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Two bugs live capture caught in the branch foldout:

DEFECT: buildBranchRows assigned groups correctly but returned
branches.map(...)'s own order -- git's listing order -- and
GroupContiguous on the Go side then renders groups in first-appearance
order, not the ratified default/recent/guarded/other order. Fixed by
sorting the built rows before returning: group rank (default -> recent
-> guarded -> other), then within a group by committedAt descending
(recent, current row always first) or alphabetically by name (guarded,
other).

SPEC CORRECTION: a non-default current branch now lands in "recent",
at the top of that section, matching GitHub Desktop (it shows the
checked-out branch inside its own section, never dumped into a generic
"other" wall). It still never counts against the RECENT_BRANCH_COUNT
budget for the other recent rows, and it still keeps its ahead/behind
pills instead of a date.

Added a section-order test that feeds branches in a deliberately
scrambled input order, with guarded/other names picked so alphabetical
order disagrees with commit-date order (ruling out a date-sort passing
by coincidence), and asserts the exact emitted order. Updated the
existing "current branch never counts toward recent-5" test for the
new group.

The golden fixture (session-model-mission.json) now carries 9 branches
-- default, current-in-recent plus 5 more recent rows (exactly the
RECENT_BRANCH_COUNT budget), a guarded row, and a genuine "other" row
-- because a 6th non-current/default/guarded candidate is the minimum
that lets one spill past the recent-5 budget; both languages'
fixture-decode tests (protocol.test.ts, model_test.go) follow the
fixture's own new shape rather than re-deriving expectations. Two Go
integration tests that relied on a fixed down-arrow count or the old
cursor-start position (mission_test.go) are updated: one now checks
out "main" directly since the default branch is the first row the
cursor lands on, the other reaches the pinned action row through an
empty-match filter query instead of a row-count-dependent number of
down-presses.

The Go side needed no ordering logic of its own: it renders whatever
order it receives.

⚠️ Action not completed

Review rate limited.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.

CodeRabbit finding on PR #353 (2026-09-19T21:38Z, changes.go), missed
mid-round and still valid: renderCommitButton rendered its label
through Width(width) without clipping. Lipgloss wraps rather than
truncates there, so a long current.branch could push "Commit N files
to <branch>" past the 46-cell sidebar onto a second row. The button is
a fixed-height block in the sidebar's own layout and sidebarHit maps
every row below it by a hardcoded offset, so the wrap would shift
everything below it -- with an undoable commit present, a click meant
for the undo chip would land one row short of it. Fixed by clipping
the label to width before it reaches Width() (clip, the sanctioned
clipper).

Swept the same class across the rest of the sidebar and every foldout
rather than fixing only that call site:

- renderMasterRow (changes.go): changedTotal/stagedTotal are driver
  ints with no practical upper bound.
- modalFilterLine (modal.go): the query is user-typed and unbounded.
- modalGroupHeaderLine (modal.go): a repo's own Group value
  (repoGroup's "host/owner") is driver-supplied and unbounded, and
  modalWidth never accounts for header text when sizing the box.
- renderNoticeStrip (modal.go): a driver refusal or view-local notice
  is free-form and unbounded, and the strip is a fixed single row the
  frame's own layout budgets exactly 1 row for.

Two of these fixes (renderMasterRow, modalGroupHeaderLine) first
reached for clipOn and produced a real background hole caught by the
existing whole-frame bg-coverage tests: clipOn's non-truncating path
renders its input through a colorless style, which is only safe when
the input already carries its own embedded fg+bg per fragment (e.g.
justify's left); passing raw, not-yet-colored text through it drops
the background entirely. Switched both to clip() wrapped in the
caller's own color, matching the established convention (renderCommitButton,
renderFilterRow, modalActionLine, renderNoticeStrip).

Verified safe, no fix needed (noted rather than touched):
renderTabsRow (fixed short labels + a bounded numeric suffix -- would
need a 15-digit file count to overflow the 23-cell tab half), the
stash/undo strips and the main keybar (already go through justify,
which clips internally), modalRowLine/modalActionLine/modalKeybarLine
(already clip), every topbar segment including the action segment's
meta (renderSegment already clips top and bottom), diff.go's hunk
headers and line text (already clipped in an earlier round, with a
comment already naming this exact bug class), and the commit
summary/description boxes (they render bubbles' own pre-sized
textinput/textarea view output, not raw driver text).

Each fix has a RED-verified test (long input, assert exactly 1 row at
the caller's width); the commit-button fix additionally gets a
layout-level test proving the undo chip's frame row and hitTest result
are unaffected by a long branch name.

Addressed in 6c94228 (rt-ui: mission clips every fixed-height row's text): renderCommitButton now clips its label to width before it reaches Width() instead of letting lipgloss wrap it, so a long current.branch can no longer push the fixed-height button onto a second row and shift the rows below it (including the undo chip).

Swept the same class (Width()/Align() on caller-supplied text with no clip/clipOn first) across the rest of the sidebar and every foldout, and fixed three more real instances: renderMasterRow, modalFilterLine, and modalGroupHeaderLine. Full reasoning, the sites verified already-safe, and a background-fill bug two of the fixes briefly introduced (and caught via the existing bg-coverage tests) are in the commit message.

Tests: each fix has a RED-verified unit test (long input, assert exactly 1 row at the caller's width); the commit-button fix also has a layout-level test proving the undo chip's frame row and hitTest result are unaffected by a long branch name. go build/go vet/go test ./... and bun run ui:build all green.

…r push

CodeRabbit finding on PR #353: getRemoteDefaultBranch runs up to two
synchronous git subprocesses (now up to three -- see the companion
correctness fix), and model() called it directly. Every push() calls
model(), so typing in the filter, moving the selection, or any notice
repeatedly blocked the UI thread on git for no reason -- the value
never changes except when the worktree does.

MissionDriver now resolves it once in refresh() (the initial load, and
every repo/worktree/checkout transition, all of which already await
refresh() before their own push()) and caches it on a private field;
model() and guardBranch() both read the cache instead of calling
resolveDefaultBranch themselves. resolveDefaultBranch joins MissionDeps
(getRemoteDefaultBranch's own type, wired from lib/git-ops.ts in
commands/glitter.ts) rather than staying a direct import, which is
what makes it spy-able for the caching test in the first place -- every
other git-touching call the driver makes already goes through this
same DI seam.

Test: a scripted sequence of four "mission:select" filter-only pushes
(no refresh in between) asserts the injected resolver ran exactly
once, RED-verified against the pre-fix code (six calls, one per
push+the initial refresh). A second test confirms a worktree switch
re-resolves rather than freezing the cache at its first value.

CodeRabbit finding on PR #353: getRemoteDefaultBranch only ever probed
origin/main and origin/master, so a repo whose remote defaults to
anything else (develop, trunk, ...) -- or whose remote isn't named
origin -- resolved to null. In mission that meant the whole "default
branch" section vanished from the branch dropdown and every row read
default: false, silently, with no error.

Three-step resolution now, each a fallback for the one before it:
1. `symbolic-ref --quiet --short refs/remotes/<remote>/HEAD`, the local
   remote-tracking symref a clone or `remote set-head` sets. Verified
   empirically against the git on this machine: a plain `remote add` +
   `fetch` sets it too (the server advertises HEAD and a modern git
   writes the symref if it's unset), so this resolves the common case
   with no network round trip.
2. `ls-remote --symref <remote> HEAD` asks the remote directly, for a
   remote added without ever fetching or an older git that never wrote
   the local symref. Bounded by a 5s timeout so an unreachable remote
   can't hang the caller.
3. The original origin/main / origin/master probes, as the last resort.

Takes the remote name as a parameter (default "origin") rather than
hardcoding it, so RT-219 (resolving the real remote name generically)
is a one-line call-site change later, not a rewrite here. Considered
init.defaultBranch as an additional fallback per the finding's own
suggestion, but skipped it: that config reflects the LOCAL convention
for branches created by `git init`/`checkout -b`, not what the remote
itself considers its default, so it would answer a different question
than the one being asked.

Sandbox tests (mirroring lib/worktree/__tests__/git-async.test.ts's own
real-repo pattern): no remote resolves to null (the existing contract,
preserved); a main-default origin still resolves via the original
probe (non-regression); a develop-default remote resolves correctly
(the bug); the same develop case still resolves via ls-remote when the
local HEAD symref is deliberately removed; the master-only probe still
covers a remote neither symref path can reach; a non-origin remote
name resolves under its own name and origin still correctly reads as
absent.

CodeRabbit finding on PR #353: renderNoticeStrip's own commit
(6c94228) clipped text to width minus the fixed chrome (leading space
+ warn glyph + gap, 3 cells), but at width 1-2 that leaves textW
clamped to 0 while the fixed chrome ALONE still exceeds width -- the
exact wrap risk the earlier fix was meant to close, just moved one
layer out. Clips the whole composed payload (glyph + gap + text) to
width-1 instead, and returns "" outright for a non-positive width (no
cell to paint into).

Tests at width 1, 2, and 3 (the narrow band the previous fix's
per-piece budget mishandled) plus 0 and -1 (the guard).

Addressed all three findings from the latest review pass:

  1. MAJOR (perf) lib/mission/driver.ts:244 — fixed in ab925566 (mission: cache the resolved default branch instead of resolving it per push). resolveDefaultBranch joined MissionDeps and is now called once per refresh() (initial load + every repo/worktree/checkout transition) and cached on MissionDriver; model()/guardBranch() read the cache. Test scripts four filter-only pushes with no refresh in between and asserts the injected resolver ran exactly once (RED-verified: six calls without the fix).

  2. MAJOR (correctness) same site — fixed in 2cdd5eaf (git-ops: resolve the actual remote default branch, not just main/master). getRemoteDefaultBranch now tries symbolic-ref refs/remotes/<remote>/HEAD first (verified empirically that a plain remote add + fetch sets this on a modern git, not just clone), falls back to ls-remote --symref <remote> HEAD (5s-bounded) for remotes/git versions where that local ref isn't set, and keeps the original main/master probes as the last resort. Takes remote as a parameter (default "origin") per the ask, so RT-219 is a one-line wiring change later. Sandbox tests cover: no remote → null, a main-default origin (non-regression), a develop-default remote (the bug), the same case via the ls-remote fallback, the master-only last-resort probe, and a non-origin remote name. Skipped init.defaultBranch as an additional fallback (noted in the commit message) — it reflects the local convention for newly created branches, not what the remote itself considers default, so it doesn't actually answer the question here.

  3. MINOR ui/internal/views/mission/modal.go:926 — fixed in e7babe20 (rt-ui: clip the entire notice payload, not just its text). The prior fix clipped only text to width - 3, so at width 1-2 the fixed chrome (leading space + glyph + gap) alone still exceeded width. Now clips the whole composed payload to width-1 and returns "" for a non-positive width. Tests at width 1, 2, 3, 0, and -1.

Gates: bun test lib/mission, bunx tsc --noEmit, go vet ./..., go test ./... (full suite, not just mission), bun run ui:build — all green. Nothing in this pass was judged invalid.

Owner ruling: the commit button at one row read thin against the
bordered boxes above it; at three rows (an earlier pass) it read too
big. The board is 32px against a 26px cell -- 1.23 cells -- a genuine
sub-cell height neither a clean 1-row nor a clean 3-row rendering can
express honestly.

Three physical rows now carry it: a half-block "cap" row above and
below the full solid label row. GlyphHalfBlockLower (▄) as the top
row's own FOREGROUND on a theme.Bg background paints only that row's
bottom half in the button color, leaving the top half as canvas;
GlyphHalfBlockUpper (▀) mirrors that for the bottom cap's top half. The
middle row is the button exactly as it always rendered -- full solid
fill, centered label, clipped before Width() (unchanged from the
CodeRabbit fix on PR #353). Enabled and disabled both use this shape;
only the color changes (Pink/Panel), same as before.

sidebarHit's fixed-offset math now maps all three rows to
hitCommitButton (previously exactly one row); sidebarDockedH needed no
manual update since it's measured by actually rendering sidebarDocked
(lipgloss.Height), not a hardcoded sum, so the docked block's growth
and the sidebar's own filler-gap shrink are both automatic. The
description→button gap row above the block is unchanged.
docs/design/mission/README.md's CommitButton geometry row and its
"net effect on sidebarBlocks" paragraph are updated in the same commit,
with the ruling that half-blocks are the sanctioned way to hit a
sub-cell height in this build; a hairline seam some fonts render
between a half-block row and its solid neighbor is accepted, not
chased.

Added TestHalfBlockGlyphsMeasureAsOneCell (▄/▀ sit in Unicode's East
Asian Ambiguous range in some width tables) alongside the existing
Nerd Font glyph measurement test -- the same footgun, a different
glyph family. Rewrote the button's own composition tests for the new
3-row shape (exact glyph rows + fg/bg for both enabled and disabled),
added a hit-test covering all three rows plus the row just past the
bottom cap (which must NOT still read as the button), and fixed two
now-stale hardcoded frame coordinates whose old values happened to sit
inside regions the layout shift moved: mission_test.go's undo-chip
click row math (still lands on the same y by coincidence -- the docked
block's growth and the list region's shrink cancel out exactly, so the
comment is corrected rather than the value) and its "sidebar filler
gap" probe cell, which real did move (row 14 -> row 13, since the
filler shrank from 3 rows to 1).

Owner ruling: the repo/worktree/branch segments' trailing chevron sat
flush against the divider. It now renders 2 cells in from the
segment's right edge -- chevron, then 2 blank cells of the segment's
own background, then the divider column.

segmentSpec gains trailingPad (default 0, unchanged for the action
segment's ahead/behind pills, which stay flush); the three chevron
call sites set it to the new chevronTrailingPad constant. renderSegment
subtracts it from both the value-text clip budget (bottomAvail) and
the gap computation before the trailing accessory, so a long repo or
branch name still clips cleanly instead of growing into the new gap
and colliding with the chevron. Hover/open fills needed no change:
row2's own base.Width(width).Render(...) already pads any trailing
space with the segment's background, so the two new gap cells are
already part of the hover/open span, not the divider's.

Segment origins, modal anchoring, and segment widths are unchanged --
this is inside the segment, not a width change.

Tests: chevron position (exactly 2 cells before the right edge) for
all three foldout segments; a long value clips without touching the
chevron; the action segment's pills stay flush (no regression from a
blanket renderSegment change). Existing hover/bg-coverage tests
(TestTopBarHoverCoversAllThreeRowsOfItsSegment and the full-frame
bg-coverage suite) pass unchanged, confirming the padding cells are
already covered.

Owner found on a real (non-fixture) plain git repo: the worktree
segment rendered a raw absolute path ("/Users/matt/Document…") instead
of a name. worktree:list has no rt-provided name for a repo it has
never registered as a worktree, and buildModel's own fallback
(worktreeRows.find(...)?.name ?? "") produced an empty string, which
mission.go's renderWorktreeSegment then falls back to Current.Worktree
(the raw path) for.

buildModel now falls back to the checkout directory's own basename
(path's own `||` covers both an empty WorktreeRow.name and no matching
row at all) before that ever reaches the view -- the segment must
never render an absolute path.

Every mission fixture models an rt-managed worktree with a
daemon-assigned name, so this path was never exercised; added directly
in lib/mission/__tests__/model.test.ts (an empty name, no matching row
at all, and the existing named case as a non-regression check).

…tamp

Owner found on a real (non-fixture) plain git repo: the undo strip
read "Committed 2026-09-20T19:21:02-05:00 …" instead of a relative
time. MissionLastCommit.when carried git-core's raw log authorDate
straight through; the view (changes.go's renderUndoStrip) has always
rendered it verbatim, so nothing was masking this on a real repo the
way every mission fixture's own hand-written "2 minutes ago" value did.

Preformatted driver-side in refresh(), the same convention
action.meta and MissionBranchRow.when already use (the driver formats
once, the view renders whatever string it gets) -- formatRelativeTime
against this.deps.now(), the same formatter and clock seam the branch
dates already share.

Owner ruling, after research into the aborted three-way reconciliation
design: rt adopts GitHub Desktop's own staging model wholesale rather
than building a reconciliation nothing in GHD or the vendored pipeline
actually needs. Verified against GHD's own source
(app/src/lib/git/diff.ts's getWorkingDirectoryDiff): the diff pane
always shows a file's full changes, independent of what's staged.

getStagingDiff now runs `git diff HEAD -- <path>` for modified/deleted/
copied/conflicted files (worktree vs HEAD, so staged and unstaged
content show together) instead of `git diff -- <path>` (worktree vs
index, which is why a fully staged file's diff used to be empty --
this is the real-repo defect the round started from). Untracked files
are unchanged (`--no-index -- /dev/null <path>`). Renamed files keep
the index-based comparison GHD itself uses and explicitly calls "the
best kind of incorrect" -- diffing a rename against HEAD would need a
rename-aware three-way comparison neither GHD nor this change attempts.

New stageFileFully(path, originalPath?) is the "All" half of the
commit-time index rebuild the driver will do next (GHD's own
stageFiles "normal" + "oldRenamed" steps): a bare `git add` handles
new/modified/deleted uniformly, and a rename recreates its old path
via `update-index --force-remove` first so the move survives a prior
full index reset. The "Partial" half reuses the existing
stageSelection (already exactly GHD's applyPatchToIndex once the diff
it's handed is the same HEAD-vs-worktree diff -- no changes needed
there).

Tests: the 12 existing stagingDiff/stageSelection/discardSelection
sandbox tests pass unchanged (none had pre-staged content ahead of a
worktree edit, so HEAD-vs-worktree and worktree-vs-index produce
identical output for them). New sandbox tests, RED-verified against
the pre-fix code: a fully staged modified file's diff shows the real
change instead of empty; a partially staged file shows staged and
unstaged edits together; a fully staged deletion shows the deletion;
a renamed file's diff still uses the index (non-regression); and three
for stageFileFully (plain modify, delete, rename recreation).

Owner ruling: rt adopts GitHub Desktop's own staging model. include
(all/partial/none) is now purely a read of the driver's persisted
DiffSelection -- file.staged/file.unstaged no longer factor in at all,
matching GHD's own checkbox semantics exactly. Every file's default
(no selection recorded yet) is All, GHD's own default, applied
everywhere buildModel used to derive a fallback from index state: the
Changes list's own include, and the diff pane's per-line selected seed.

stagedTotal/canCommit/commitPlaceholder/commitButtonLabel needed no
code changes at all -- they already read `change.include`, which now
means "checked" automatically once deriveInclude switched semantics.

Golden fixture updated to match: a freshly-added file with no selection
recorded now reads "all" (was "none", derived from its unstaged-only
index state) -- buttonLabel and stagedTotal follow (3 checked files,
not 2 staged ones). Existing per-line/per-file tests that exercised the
OLD file.staged/unstaged-derived fallback are rewritten to exercise the
new selection-only default and its explicit override, rather than
testing behavior that no longer exists.

Owner ruling: rt adopts GitHub Desktop's own staging model wholesale.
mission:stage (line, hunk, toggle-file) now only ever mutates the
driver's own DiffSelection map -- it never calls git. Toggle-file
flips a tri-state checkbox's own click rule (Partial/None -> All,
All -> None); line/hunk toggling just flips the bit, in either
direction, since there's no longer a "can't unstage" limitation to
refuse around. RT-221's "line unstage is impossible" residual
dissolves under this model: unchecking a line was always just
deselecting it once staging stopped being a git call.

The real git index is rebuilt exactly once, at commit time
(rebuildIndexFromSelections), following GHD's own sequencing
(app/src/lib/git/commit.ts's createCommit): reset the whole index to
HEAD, then walk every changed file and bring the index to match its
own selection -- None needs no call, All is stageFileFully (this
round's git-core addition), Partial re-fetches the file's own
displayed diff and applies exactly the checked lines via the existing
stageSelection (already exactly GHD's applyPatchToIndex once handed
the new HEAD-vs-worktree diff). Anything staged outside glitter --
a plain `git add`, another agent working the same repo -- is rebuilt
away here, matching GHD's own accepted behavior.

Selections now persist across the whole session as the user's actual
commit intent, not derived state: reconcileSelections (called from
every place that replaces the driver's snapshot) seeds a newly-
appeared file to All and prunes one that's gone, but never touches an
existing entry -- a selection made before an unrelated git-status-
triggered refresh survives it. discardSelection's own path drops its
file's entry deliberately: a discard changes the diff's shape, so any
persisted selection's absolute indices no longer point at the same
content, and reconcileSelections re-seeds it fresh.

stageFile/unstageFile are gone from MissionDeps -- selection-only
staging has no whole-file git primitive to inject -- and their sole
implementations, commit-ops.ts's stagePath/unstagePath, are now dead
and removed (grepped clean across the repo first).

Tests: driver.test.ts's staging suite rewritten for selection-only
behavior (a line/hunk toggle flips exactly that bit, in either
direction, with zero git calls; toggle-file's tri-state rule), a new
suite pinning the exact commit-time dispatch (None/All/Partial routed
to the right call, including a rename's originalPath reaching both
stageFileFully and stageSelection), and a new suite proving a
selection survives a git-status-triggered refresh. compose.test.ts's
real-sandbox round trip is rewritten to the ticket's own ask: a file
partially selected (one line deselected) commits exactly its checked
content and leaves the rest in the working tree; a file toggled off
entirely is excluded and stays untouched; both are RE-SEEDED to All
after the commit (their own remaining/untouched content reappearing
fresh, GHD's own default). Two git-core conformance tests (hostile
unborn-HEAD and mid-merge-conflict states) are re-pinned to the new,
verified-against-real-git actual behavior their own file's stated
methodology calls for, now that getStagingDiff names HEAD explicitly.

Owner-verified real-repo defect: rows reordered when files got staged,
because the Changes list rendered snapshot.files in git status's own
order, which regroups as the index changes. Verified against GHD's own
source (app/src/lib/stores/updates/changes-state.ts's
updateChangedFiles, line 61): it sorts the merged working-directory
files case-insensitively by path on every status refresh, independent
of staged/selection state. buildModel now does the same --
caseInsensitiveComparePath mirrors GHD's own caseInsensitiveCompare
(app/src/lib/compare.ts: lowercase both sides, ordinal comparison, not
locale-aware collation) -- so a row's position depends only on which
paths are present, never on how git status happened to list them or
what got checked.

That same GHD function is also the reference implementation for last
round's selection-persistence work, and reading it in full surfaced a
real gap in what was built: GHD carries a file's selection forward
UNCHANGED across a status refresh, with one deliberate exception --
when the caller marks the refresh as one where partial state should
clear (right after a commit, or after a display setting that shifts
line numbers), a Partial selection downgrades to None rather than
riding forward at now-stale absolute indices. The driver's own
reconcileSelections already did the "carry forward unless new/gone"
half correctly; handleCommit's blanket `selections = new Map()` did
not -- it wiped a deliberately-unchecked file's None right alongside
the just-committed Partial ones, so an untouched file would spring
back to fully-checked after an unrelated commit. Fixed to GHD's exact
rule: only Partial entries downgrade to None; All/None are left alone
regardless of the diff's shape, since neither carries index-specific
meaning. handleDiscard's own stale-selection cleanup (a discard shifts
a file's diff shape exactly like a commit's remainder does) is fixed
the same way instead of an unconditional delete-then-reseed-to-All.

Tests: a scrambled snapshot.files order and two different orderings of
the same file set both render identically sorted; mixed-case paths
sort case-insensitively (not raw byte order); the selected file's diff
still resolves by path (not row index) across a reorder. The compose
round trip's post-commit assertions are corrected to the now-accurate
behavior: a partially-committed file's leftover content reads
unchecked (None), not reseeded to All, and the deliberately-excluded
file's None persists rather than springing back to checked. Golden
fixture and its Go/TS decode assertions updated to the new sorted
order (mission.go, model.go, topbar.go -- 'i' < 'o' < 't'); four Go
mouse/keyboard row-position tests updated to the same reordering.

…badge

On a repo the daemon has never swept (a brand-new, never-registered
worktree), currentBadge() fell back to EMPTY_GIT_BADGE, so the action
segment claimed "Publish branch · Never fetched" even when the branch
demonstrably has an upstream and is ahead -- confirmed and scoped in
the previous round's report, built now.

this.snapshot's own upstream/ahead/behind are already fetched live on
every refresh, independent of the daemon sweep, and were sitting
unused for exactly this fallback. currentBadge() now builds a
synthetic badge from them when no daemon badge exists for the current
worktree, leaving lastFetchedAt null (that specifically answers "has
the daemon fetched," which the live snapshot has no way to know) and
dirty-file counts at their EMPTY_GIT_BADGE defaults (out of scope --
deriveAction never reads them). currentRepoBadges()'s own per-row
usage (the worktree modal's list of every worktree, not just the
current one) is untouched: an unswept OTHER worktree still reads as
empty until its own sweep lands, which is correct there.

Tests: the existing "never borrows another worktree's badge" case is
narrowed to a snapshot with no upstream at all, isolating it from the
new fallback; a new test gives the live snapshot a real upstream and
ahead count with no daemon badge and asserts the action reads "push"
(not the false "publish-branch") while meta still correctly reads
"Never fetched" (a true daemon-fetch fact, not the wire's own to
disprove).

Records the ratified 2026-09-21 staging model plainly, in both places
someone would look: docs/design/mission/README.md gets a full section
(the diff pane always shows HEAD-vs-worktree, checkboxes are commit
intent not index state, the commit-time reset+rebuild sequencing, the
Partial-selection-downgrades-to-None persistence exception, and
RT-221's line-unstage residual dissolving under this model);
CLAUDE.md's rt-ui section gets a short pointer stating the consequence
that actually bites: anything staged outside glitter is rebuilt away
at the next commit, worth knowing plainly since this estate routinely
has multiple agents working the same checkout.

Two explicit real-sandbox scenarios the staging-model round's own test
list called for but the initial round trip didn't cover directly:

- A file staged entirely outside the app (a raw `git add`, standing in
  for another agent editing the same repo concurrently) still defaults
  to checked (the checkbox has no idea what's in the index), but once
  unchecked, the reset-then-rebuild sequencing at commit time excludes
  it completely -- the commit takes only what's checked, never what
  happens to already be in the index.
- Amend still works with the new sequencing: a first commit, then a
  new file appearing and getting checked before an amend, folds
  correctly into the replaced commit (still one commit replacing the
  first, not a second stacked on top) alongside the already-committed
  content. Also confirms a deliberately-unchecked file's None survives
  across the first commit rather than springing back to checked.

CodeRabbit finding on PR #353: getRemoteDefaultBranch early-returned on the
local refs/remotes/<remote>/HEAD symref, which a plain fetch never
refreshes once set. After a server-side rename (main -> trunk) that symref
goes stale forever, and it fed sync, rebase --origin-detection, reset
--origin, and the amend/undo history-rewrite guard.

Ruling: query-remote-first for every caller above (network already in
play, correctness over latency), but keep mission's own interactive
per-refresh resolve local-first -- it is display state read on every
redraw, not a mutation, and a network round trip there would make the TUI
network-bound and slow/broken offline.

- getRemoteDefaultBranch takes an opts.preferRemote flag that swaps the
  probe order (remote ls-remote first, local symref as fallback); the
  final origin/main and origin/master probes stay the last resort either
  way.
- sync.ts, git/reset.ts, git/rebase.ts, and git/mutate.ts's history-rewrite
  guard (amend, undo) now pass preferRemote: true.
- lib/mission/driver.ts's cached per-refresh resolve is unchanged: it
  already only reaches this function with the default (local-first)
  ordering.
- runAction (mission's fetch/pull/pull-rebase) now re-runs
  `git remote set-head <remote> -a` after a successful action, so the
  local symref self-heals on the actions users already run constantly and
  the local-first path stays honest in practice.

Tests: preferRemote returning the renamed branch vs. the default ordering
returning the cached one (both pinned, with a comment on why they differ);
preferRemote falling back to the local symref, not throwing, when the
remote is unreachable; fetch refreshing the local symref end to end.

Addressed the CodeRabbit finding on lib/git-ops.ts:64 (getRemoteDefaultBranch early-returning on a stale local symref) in cc72544.

Per ruling: rather than always querying the remote first (which would make mission's interactive per-refresh resolve network-bound), getRemoteDefaultBranch now takes an opts.preferRemote flag that reorders the two symref probes. Mutation call sites pass it:

  • commands/sync.ts (default-branch detection ahead of a sync's reset/rebase)
  • commands/git/reset.ts (divergence-direction disambiguation in resetToOrigin)
  • commands/git/rebase.ts (default target-branch detection)
  • commands/git/mutate.ts's guardHistoryRewrite (amend/undo's ownership guard)

lib/mission/driver.ts's cached per-refresh resolve (glitter's interactive board) is unchanged -- it's display state, not a mutation, and already only calls the function with the default local-first ordering.

Closed the staleness window on the fast path too: runAction (mission's fetch/pull/pull-rebase) now re-runs git remote set-head <remote> -a after a successful action, so the local symref self-heals on the actions users already run constantly, non-fatal on failure.

Tests added in lib/__tests__/git-ops.test.ts and lib/mission/__tests__/git-actions.test.ts: preferRemote vs. default ordering pinned as deliberately different answers after a server-side rename, preferRemote's clean fallback when the remote is unreachable, and fetch's end-to-end symref self-heal.
