fix(statusline): preserve model name against wide working directory and git paths

[santhreal]

What was wrong

RIGHT_PART_SHED_RANK on the composer footline ranked context_pct, mode, location_right and
subagents, and left model unlisted. Unlisted ranks 0, and rank 0 is shed before the location
zone is shortened, so a wide working directory plus a long git branch dropped the active model name
off the line while the untruncated path and branch kept every column they wanted. Nothing on screen
said which model was answering until the terminal was widened.

Two more defects sat on the same line. The location zone was clipped from BOTH ends, because the
component's width-driven shortening cut from the right while clampPathLength cut from the left:
…orm-services/ingest-pipeline/normalize… named neither the project the path sits under nor the
directory it is in — it threw away the one end that identifies where the session is. And every click
target on the footline — the context gauge, the secrets chip, the goal readout — was inert in a
session whose transcript had not yet overflowed the viewport.

The change

• model: 2 in RIGHT_PART_SHED_RANK, between context_pct (1) and mode (3). The location zone
  now shortens first: a clipped path still says where you are, and the model identity does not
  degrade.
• renderQuietLine clamps each location part's recorded bounds to visibleWidth(left). Without it a
  part whose content extends past the truncation point reported a slot running into the right group,
  so a footline click resolved to a segment that was no longer on screen.
• Both clippers cut the FRONT. A clipped path carries exactly one ellipsis, at the start, and reads
  as a suffix of the path on disk, so the directory the session is in is the part that survives:
  …ine/normalizer rather than …orm-services/ingest-pipeline/normalize…. The width-driven cut
  inherits a mark already in the text instead of stacking a second one on it — the two clippers
  together painted ……orm-services/…, the both-ends defect recurring one end at a time.
• The location zone clips the directory and the branch from THEIR OWN FRONTS, together, and drops
  neither while the row can hold them. Shedding the branch whole was the first shape of this fix and
  it took the branch off rows where the release before it still showed it clipped, so the parts are
  water-filled instead: the widest clippable part gives up one cell at a time, ties go to the branch,
  and both converge on a shared width. A part at or under twelve cells is never asked at all, so
  main reads whole at every width and only a long branch pays. The path keeps its icon in front of
  the mark, because the worktree, scratch and folder glyphs are the only thing telling a worktree
  from any other two-segment path. Cutting the front of the joined path · branch is the same
  mistake in a second form: the tail of that join is the branch, so one cut across it kept
  …tion-long-path and dropped the directory entirely.
• Below the zone's floors the BUDGET moves rather than the text: the context gauge is shed and the
  zone is asked again. A percentage re-reads on the next frame, while the directory and the branch
  are what the row is for. The ladder stops one rung short of the model chip, since retaining that
  chip beside a long path is what this branch is about. Only a budget too small for the separators
  and the unclippable parts drops a part at all, and what it keeps is the DIRECTORY: a lone main
  says nothing about where the session is.
• The fitter reports the painted extent of every location part, so a recorded click slot is the
  columns on the screen rather than the columns of the join it was cut from, and a part clipped away
  takes its separator with it instead of stranding a · no segment owns.
• The clamp is a budget rather than a width, so no terminal was wide enough to show a long path. A
  click on the location text (path, branch or pull request) toggles #pathExpanded: the zone gives
  up the preset clamp and takes the row, and the model chip steps aside to pay for it. A second click
  restores both. The expansion belongs to the line, not the session — it is not persisted and it
  re-truncates on resize rather than holding the width it expanded at.
• The trade TRAVELS. One SettleValue on MOTION.expand drives both ends of it, so the row can
  never be half-widened with the chip already gone: the path's budget interpolates toward the row
  while the chip is clipped by the same progress, and the value lands byte-for-byte on the row the
  click paints with no motion at all. Frames come from the repaint hook the mode passes in, not from
  a timer this component owns, so a component with no hook lands on the click frame — which is
  also what display.transitions: off does, through set() then finish().
• QuietZoneLine.wantsPointer() declares the mouse grab whenever the line has a click handler.
  Button reports only arrive while the engine holds the mouse, and it takes the grab when the frame
  overflows the viewport OR a pinned-footer child asks for it. A fresh session satisfies neither: the
  only footer child that ever asked was the shortcuts bar, which renders no chips at rest. So the
  gauge, the secrets chip and the goal readout answered a click later in a session and not at the
  start of one.
• The default-branch lookup behind the branch decoration is wrapped like the two fire-and-forget git
  lookups beside it. git() REJECTS when the binary is missing rather than returning a non-zero
  result, and this was the one unawaited lookup in the component that let that escape, so a directory
  holding a .git on a host with no git on PATH raised an unhandled rejection out of a render. The
  wide-location fixture is what surfaced it: it is the first status-line suite with a real .git to
  resolve.

The zone that was not there

A draft in a 78-column terminal is where the layout was found out. The composer pins a token
estimate to the location line while text is being typed, and with the estimate on the row the
working directory and the branch left the footline altogether -- not clipped, gone -- beside
twenty-one cells of empty middle. Then what was left rendered against the LEFT margin, half a
screen from where the state chips sit on every other row.

Two separate faults, one frame.

• The fit latched. The zone was fitted once, against the room a right group left while it still
  held the session name and the context gauge: a budget of ZERO, so the zone painted nothing and set
  a locationShortened flag. Those two parts were shed a moment later and nothing asked the fitter
  again, so twenty-one freed cells went nowhere. The fit is now re-taken every time a part is shed
  on the zone's behalf, and once more when the group has stopped shedding -- the shed that ENDS the
  fitting frees cells too, and at forty columns nobody was handing those over either.
• The offset was borrowed from a neighbour. The right group was placed at budget - width(right)
  only when a location survived to sit beside it. With no location the offset was zero. It is
  anchored to the right edge now, location or not.

And a ladder the first fault was hiding. A zone cut under the width at which a name reads --
…izer · …g-path, two fragments that each read as a name in their own right -- is the answer of
last resort, so the row now pays for the zone with what the next frame re-derives: the context
gauge, the context total, the draft estimate. Never the model chip, which is what this row exists to
retain, never a mode rung, which says what the next keystroke does, and never the running-subagent
count, which is the part the row sheds last of everything -- paying with it lost the count while a
rung it outranks stayed, and on a row holding nothing else it spent the count and returned no
footline at all. Below the
width where the zone can hold an icon, a mark and one letter of a name it paints nothing at all,
because …er names no directory and no longer even says this is a worktree.

Two more calls looked like part of this fix and were not. Mutating each one away left the suite green
across three presets and every width from 130 columns down to 6, so both are gone rather than shipped
as decoration: the fit ladder cannot leave a stale zone behind, and a spend the zone cannot use is
never reached.

The draft state at 78 columns, before and after:

Two things the frames turned up, neither fixed here

Both are pre-existing and both take every footline click target down together, the gauge included,
so neither belongs to this branch.

• The footline needs the mouse. Reports only arrive while the engine holds it, which is
  tui.scrollIsolation, off by default because the grab costs drag-select. With it off no footline
  click can fire. The capture arms below run with it on, which is the operator's own opt-in and what
  the gauge has always needed.
• A confirmation dialog ends footline clicking for the session. Once one has opened and closed —
  /goal drop and /yolo both raise one — the footline answers nothing: three attempts on the row
  the text is on changed nothing, while the same click lands in idle, under a rung, under /loop and
  under /plan before any dialog has been shown. That is why the expanded-path frame is shot first
  in the scene rather than beside the bypass.

The mark

A clip mark is part of the name it cut. Two things about the old one said otherwise.

• It wore the wrong colour. The mark was written ahead of the escape run sliceWithWidth
  replays at the cut, so it painted in whatever the row was in before the part: the separator's
  grey in front of a green branch. One glyph in the gap's colour reads as belonging to the gap. It
  is emitted after that run now, so each mark is painted in the colour of the name it cut.
• It opened on punctuation. A cut placed by arithmetic alone lands wherever the budget runs out:
  …-model-retention-long-path opens on a dash belonging to a word the row no longer shows. The
  cut walks forward up to four cells to the next boundary, keeping a / -- a mark in front of a
  slash is how a shortened path has always read -- and dropping a word separator, which has nothing
  left to join. Four cells, so no row loses a name to tidiness, and never past the point where the
  part would fall under its floor: the first version of the snap took a thirteen-cell branch to nine.

columns	before	after
118	▫ …gest-pipeline/normalizer · …-model-retention-long-path	▫ …gest-pipeline/normalizer · …model-retention-long-path
98	▫ …ine/normalizer · …ention-long-path	▫ …/normalizer · …ention-long-path

clipPartToWidth hands the pin to the clipper instead of slicing it off first. A slice of a slice
carries the sequences the first replay emitted, in an order that need not end on the one in force,
so a mark in front of an icon came out in the icon's colour; one slice of the part's own content
replays the state at the cut correctly.

Both are asserted at the fitter rather than at a row, because a row reaches these budgets only
through its shed ladder -- which drops the whole zone before the tightest of them -- and a row's
parts come coloured by the theme, which renders colourless under the test sandbox. Five mutations,
each red: the mark takes no colour; the mark takes the tail slice's replayed prefix, which is the
shape the defect had; CLIP_SNAP = 0; the boundary map inverted; and CLIP_SNAP = 100, which buys
the tidiness with whole names.

Where the cut already landed on a boundary the text is unchanged and only the colour is: the escape
run in front of the mark goes from 39, the default the separator left the row in, to the part's
own 38;2;184;189;199 for the directory and 38;2;111;175;122 for the branch.

Evidence

A display root you name, off and on

The path segment stripped two compiled-in roots off the front of a working directory before
folding the home directory to ~: ~/Projects, and /work, which nothing in this repository
mounts. It is now statusLine.segmentOptions.path.displayRoots, and a named list replaces the
defaults rather than extending them.

Both arms come from one scene, proof/scenes/statusline-display-root.sh, at 1920x1000 in the
same seeded project on the same branch. The only difference between them is the value seeded into
the recording profile's config.yml before the session starts.

Off, at the defaults — neither default root contains the project, so the path keeps its full
depth and the 40-cell budget clips its head:

On, with displayRoots: ["~/platform-services"] — the two directories above the project come off
the front and what is left fits whole, with no clip mark:

The width is part of the proof. At 118 columns the location zone is about twenty-five cells, less
than either arm's path, so both arms clipped to the same tail and the pair showed nothing; the
frames were taken there first and were comparable. 160 columns is the narrowest width at which
the setting is visible at all.

Inside tmux, and on the other platform's separator

tmux forwards a mouse report to the pane's application while that application has enabled mouse
reporting, and consumes it for its own bindings otherwise. The footline's click targets rest on the
first half of that sentence, so both arms of tmux's mouse option were recorded from one scene
(proof/docker/tmux-host.sh, new here) at 118 columns. All four clicks land in both arms, and the
row is the same row: the directory click paints
~/platform-services/ingest-pipeline/normalizer with the chip retracted, the branch click paints
feature/statusline-model-retention-long-path, and each second click puts it back. tmux's own
status line is under the footline in the frame, which is what says the session is in a pane.

Two cross-platform defects in the clip itself came out of the same pass and are fixed here.
shortenPath rewrites \ to / only for a path under the home directory, so a Windows session
in C:\work\... reached the boundary table with its own separator intact and the table did not
list it: no character in such a path was a boundary, and every clipped path on that platform opened
mid-name. And clampPathLength compared String.prototype.length against a budget counted in
columns everywhere else, so a directory named in wide characters was clamped at about half the
width it painted, and a slice on code units could cut a surrogate pair in half.

Unverified, and stated rather than implied: the pointer on ConPTY. Nothing on the click path is
platform-gated, and Windows Terminal reports SGR 1006, but no capture of it was taken -- the only
Windows host here is an operator desktop, which a scene may not drive.

Every state the footline can hold, at three terminal widths. Both arms of every pair come
from one driver (proof/scenes/statusline-widths.sh) at the same width, cwd and settings, so
the only difference in a row is the fix. The before arm holds each changed packages/*/src/*
file at its main content for the run and proves the restore by sha256.

The segment composes three independent facts — the /yolo bypass marker, one base mode from
BASE_MODE_STATES, one approval rung from AUTONOMY_LABEL — so the states do not shed at the
same width: a terminal that fits Auto does not fit ! YOLO · Plan. The expanded path is the
one row that is not a mode: the before arm has no handler for the click, so it shows the
collapsed path against the after arm's full one.

The clip below is the pair for the animation, because a still cannot show a travel: it holds the
same width, driver and settings in both arms and clicks four times — twice on the directory, twice
on the branch — with the real pointer visible on the row. proof/scenes/statusline-click.sh.

The click, under a real pointer

Click the directory, click it again, then click the branch. The name that was clicked is shown
WHOLE -- the row spends the model chip and then its remaining readouts, weakest first, to buy the
cells -- and the second click on the same half returns every part. Only a name longer than the entire
row stays clipped. The before arm answers all four clicks with a footline that never moves: main has
no handler for the report, and its branch is cut from the END, which is the other half of what
changed. Same driver, width, settings and cwd; 1440x1000 both arms.

Before	After

The same click on a narrow terminal (1100px, 89 columns) -- the width where the trade is tightest,
and where three defects lived:

collapsed          …pipeline/normalizer  ·  …retention-long-path  Qwen2.5 1.5B (local)  ·  Auto  ·  0
directory clicked  ~/platform-services/ingest-pipeline/normalizer  ·  …retention-long-path  Auto  ·  0
branch clicked     …gest-pipeline/normalizer  ·  feature/statusline-model-retention-long-path  Auto  ·  0

The click paid with the chip and nothing else, so on a row where twenty cells were not enough the
reader clicked a name and got a slightly longer clipped name. It now spends the rest of the bar.

It lost even those cells. The chip retracted BEFORE the shed ladders ran, so the narrower right
group took the pressure off a context gauge the collapsed row had already given up; the gauge came
back and took all twenty. The zone moved one cell, and the click read as a flash -- a gauge in, a chip
out, a path that stayed where it was. The retraction is settled after the ladders now, so they reach
the collapsed row's decisions and the freed cells have nowhere to land but the location.

The row stepped backward before it opened. The path's own clamp and the room being freed were two
interpolations of one progress value, racing, and the clamp won: it lengthened the path four cells
before any room existed, the ladders clipped the zone to fit, and its right edge moved LEFT for the
first three frames of every click. The room is now measured from the location's current text, which is
already on the curve. The travel steps 59, 60, 62, 64, 68, 73, 81, 88 cells while the chip narrows 17,
16, 14, 12, 8, 3, 0.

MOTION.expand (180ms, easeOutQuint) is right for a popup revealing content and wrong for text
already on screen being read across a grid whose smallest step is one cell: most of a front-loaded
curve lands inside two or three frames, so the row jumped and then crawled through its tail. This
travels on MOTION.reflow -- 320ms, symmetric.

📝 Walkthrough

Walkthrough

The status line now preserves model content during width shedding, clips paths from the front, supports animated location expansion, handles early footline clicks, and retains the main fallback when Git lookup fails. Regression tests and paired X11 proof workflows cover the updated behavior.

Changes

Status-line behavior and validation

Layer / File(s)	Summary
Status-line rendering and interaction packages/coding-agent/src/modes/components/status-line/*, packages/coding-agent/src/modes/components/composer-chrome.ts, packages/coding-agent/src/modes/interactive-mode.ts	The status line preserves pinned path icons and model content, fits location parts within readable floors, clips paths from the front, animates expansion, preserves right alignment, handles early clicks, and falls back to "main" when Git lookup fails.
Status-line regression coverage packages/coding-agent/test/modes/components/status-line/*, packages/coding-agent/test/status-line-path.test.ts	Tests cover clipping, fitting, shedding order, model retention, segment bounds, colors, presets, two-line rendering, motion, pointer routing, and segment inventories.

X11 proof capture

Layer / File(s)	Summary
Wide-path fixture and capture workflow proof/docker/*, proof/scenes/*	The proof fixture adds a long-path Git project. Scene helpers validate visible rows and click targets. The click scene records before and after behavior. Recorder configuration forwards the selected arm and output directory.

Review and proof guidance

Merge Risk: 🔵 Low · up to 4598a

The PR improves statusline truncation, model visibility, path expansion, and click handling, but switching sessions can still carry over an expanded path and hide the new session’s model name, while some proof scenes may capture misleading states. The change is mergeable with explicit owner follow-up on these bounded issues.

proof/scenes/statusline-widths.sh (1)

73-85: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Gate the draft and plan-off frames like the other states.

shot draft (Line 79) and shot plan-off (Line 85) run with no screen_has check. The idle, yolo and plan-and-yolo states each set MISSED when their proof does not land, and Lines 87-91 refuse to publish the take in that case. A composer that did not accept the typed draft, or a /plan toggle that did not turn off, still produces a published frame today.

Add a check for each state so the same gate covers all five frames.

♻️ Proposed change

 clear_composer
 t "rewrite the ingest normalizer so a malformed record fails closed instead of coercing"
 settle 2
+screen_has "coercing" || MISSED="${MISSED:-} draft"
 shot draft
 
 # BACK TO A SINGLE RUNG, so the pair at this width also shows the line recovering rather
 # than only degrading.
 slash "/plan"
 settle 3
+screen_has "Plan" && MISSED="${MISSED:-} plan-off"
 shot plan-off

Note: choose the plan-off needle that matches the rendered footline in your harness; the point is that the state is asserted before the frame is kept.

209-218: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Record a part as shed only after it was seen on screen.

shed.add(id) runs on every width where the id is absent, including the first iteration at width 130. An id that never renders in the active preset is therefore added to shed at the widest width. The assertion on Line 218 then passes without any real degradation, and the monotonic check on Line 211 becomes vacuous for that id.

Track "seen present at least once" first, so the final assertion proves the sweep actually degraded each part.

♻️ Proposed change

+		const seen = new Set<string>();
 		const shed = new Set<string>();
 		for (let width = 130; width >= 8; width--) {
 			expect(statusLine.renderQuietLine(width, { locationRight: "mcp 3/3" })).not.toBeNull();
 			const present = renderedIds(statusLine.getQuietSegmentBounds());
@@
 			// Shedding is monotone: narrowing the terminal never restores a part.

Guard the paused-goal frame before capture.

settle 3 does not prove that /goal pause changed the state. If the command fails or leaves Goal unpaused, shot mode-goal-paused records a mislabeled frame. Add an expect_screen check for the paused Goal display before shot.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not capture the pointer when the footline has no active target.

InteractiveMode assigns onClick unconditionally. When statusLine.enabled is false, the footline renders only a focus badge or no content, but this method still returns true. The line then captures mouse input although no click can succeed.

Gate pointer capture on active rendered targets, or clear the handler when the status line is disabled.

Reset expansion when the attached session changes.

setSession() replaces the status-line session but leaves #pathExpanded unchanged. If the user expands the parent session path and then focuses another session, the new session starts with its model chip hidden.

Reset #pathExpanded in the sessionChanged branch of setSession().
