The shipped panel was functionally right — every number matched git — but it
was not the approved design. I implemented from the plan's semantics (which
state is green, when to flag stale) and let the mock's layout drift, and
nothing caught it: the tests asserted behaviour, and no assertion covered
structure. Three deviations, now closed against docs/mockups/project-detail-git.html.
1. The sync band was compressed into one row of chips. Restored to the four
labelled cells: Upstream / To push / To pull / Fetch, with display-size
numerals and a footnote under each count. The footnotes are load-bearing,
not decoration — "Last fetched 19d ago — this number cannot be trusted" is
what tells a reader WHY the zero is suspect. Compressed to
"fetched 19d ago", the causal link was left for the reader to infer, and
not having to infer it is the entire point of the panel. The unverified
state is a chip on the count again, so the doubt attaches to the digit.
2. The working-tree count sat inside the band. Moved to the title line beside
the branch, where the design puts it: the band is about the remote, and the
dirty count is not. Reads "● 3 uncommitted" instead of a bare dot; the dot
remains as the fallback when a server sends no count.
3. Worktree rows were the old single line with the path right-aligned against
the chips. Rebuilt as the two-line card the design calls for — identity and
state on top, path underneath — plus the Open button, which was specified
and simply missing, so a worktree row could be read but not entered. Open
reuses the detail view pointed at the worktree path: a linked worktree is a
project directory, so this needs no new concept and no new route.
Also added the unpushed count beside the commit-list heading, so the number is
readable before the eye walks the rows hunting for rails.
Tests now assert structure, not just behaviour: cell captions exist, the stale
footnote says why, counts render at display size, the path is outside the chip
row, and Open fires with its worktree. That is the gap that let the drift
through, so it is the gap that is now covered.
Verified: tsc and build clean; npm test green (unit 78 files / 2159, e2e 27).
The page carried one bare `●` for "dirty" and nothing else, so "do I have
commits I haven't pushed" and "which worktree am I in" still meant dropping
into a terminal. Design mock: docs/mockups/project-detail-git.html; plan and
task breakdown (G1-G7): docs/plans/w6-project-git-panel.md.
One rule drives the whole feature: ahead/behind compare against `@{u}`, a
LOCALLY CACHED remote ref that only a fetch moves. This repo was the live
example while building — `↑9` true, `↓0` false, because FETCH_HEAD had not
moved in 19 days. So:
- `ahead` needs only local refs and is never flagged.
- `behind` is flagged `stale` once FETCH_HEAD is older than an hour.
- Exactly ONE state may render green: ↑0 ↓0 AND a fresh fetch. Green means
"I checked, ignore this"; getting it wrong is lying to the user.
- No upstream (the normal state of a fresh worktree branch) leaves ahead and
behind undefined — it renders an explicit `no upstream`, never the green
path. That fall-through is the easiest bug to ship here.
What landed:
G1 SyncState (upstream/ahead/behind/lastFetchMs/detached) + ProjectDetail.sync
and .dirtyCount. All additive and optional — the Android and iOS clients
decode these shapes. The ahead/behind helper already existed for the list
view; buildProjectDetail had simply never called it.
Fixes a pre-existing bug on the way: readBranch read <repo>/.git/HEAD
directly, so it returned nothing inside a LINKED worktree, where .git is a
file. resolveGitDirs now resolves both the per-worktree gitdir (HEAD) and
the shared common dir (FETCH_HEAD).
G2 POST /projects/git/fetch. Same discipline as push: the remote is derived
server-side and no remote or refspec is ever read from the body, so a
client cannot aim it at an arbitrary URL. Touches refs/remotes only — no
working tree, no index, no merge; it is not a pull. Own rate-limit bucket
so refreshes cannot eat the budget a real push needs. On failure
lastFetchMs is left alone, so the UI keeps saying "stale" instead of
pretending it refreshed.
G3 makeSyncBand replaces the bare dot: upstream name, ↑n, ↓n, stale flag,
dirty count, Fetch button (disabled on a detached HEAD).
G4 The commit list marks unpushed commits and draws the upstream boundary
once, after the last of them. Marking is server-side from `rev-list`,
deliberately NOT "the first N rows": `git log` is date-ordered, so merging
an older branch interleaves unpushed commits BELOW pushed ones, and that
shortcut fails in the dangerous direction — calling an unpushed commit
pushed. A regression test builds exactly that backdated-merge shape.
G5 The worktree section is always "Worktrees (n)" (it used to rename itself
to "Branch" at n=1) and the current row carries its own state chips.
G6 Cost control. The plan called for a .git-mtime cache; that was dropped
during implementation because a fingerprint over HEAD/index/reflog does
NOT move when push updates a remote-tracking ref — the cached `ahead`
would still claim "9 to push" right after a successful push, which is the
exact lie the feature exists to prevent. Replaced with three measures that
cannot go stale: in-flight coalescing (N devices watching one repo cost
one probe, entry dropped as it settles, nothing cached across time),
skipping the re-render when the payload is byte-identical (this also stops
the 5 s re-mount of the commit log, two more git spawns per tick), and
pausing the timer while the document is hidden.
G7 Per-worktree state via GET /projects/worktree/state, kept narrower than
/projects/detail so N rows do not pay for worktree listing and CLAUDE.md
reads nothing renders. Needed an unplanned prerequisite: ProjectSessionRef
carried no cwd, so sessions could not be attributed to a worktree. Added
it, plus countSessionsByWorktree, which matches DEEPEST-first because
.claude/worktrees/<name> lives INSIDE the main checkout and prefix
matching would count every worktree session against the parent repo too.
Out of scope, unchanged: no reset, no checkout, no clean, no rebase, no
force-push. stage/commit/push stay exactly as they were.
Verified: tsc and build clean; 46 new tests.
Fan ONE prompt across N branch/agent lanes: N worktrees, N Claude sessions on the
same prompt, watched side-by-side in the split-grid board, approve/kill per lane,
🏆 keep the winner (losers' worktrees removed). ~90% composition of shipped parts.
- src/http/session-groups.ts (new, pure, no git exec): deriveRepoRoot /
groupSessionsByRepo (cluster sessions by their <repo>-worktrees parent).
- GET /live-sessions/grouped (read-only; registered BEFORE /live-sessions/:id so
"grouped" isn't captured as an id). MAX_FANOUT_LANES env (default 6, = grid-6 cap).
- public/fanout.ts (new, pure): buildFanoutCmd shell-quotes the prompt (single-quote
wrap with '\''-escaping so $(...)/backticks/;/&& can't execute) + collapses newlines
+ caps 4000 chars; laneBranch/slugify. Effective N = min(lanes, maxFanoutLanes, 6),
≥2; the maxSessions cap is enforced server-side ("Started K of N" banner).
- public/tabs.ts launchFanout (N× createWorktree → openProject w/ prompt pre-injected
via the existing initialInput) + keepFanoutWinner; public/projects.ts renderFanoutForm
+ extracted shared createWorktreeReq (DRY). Byte-shuttle preserved (lane = own PTY).
One-click merge deferred (winner session stays open for a manual merge).
Reused unchanged: createWorktree/removeWorktree, addEntry/initialInput, split-grid +
per-quadrant approve/maximize/monitor + gauges. Verified: typecheck + build:web clean,
2063 pass at --test-timeout=30000 (only the known tmux/PTY flake red). Fixed 3
/config/ui exact-shape tests to include the new maxFanoutLanes field.
Closes the create-only loop — delete losing worktrees and prune stale ones without
a terminal. Destructive, so guarded hard:
- src/http/worktrees.ts: removeWorktree + pruneWorktrees (execFile, no shell, never
rm -rf; git worktree remove [--force] / git worktree prune). Safeguards:
(1) target realpath must match an entry git itself reports in `git worktree list`
for THIS repo → 404 otherwise (arbitrary FS paths never match, so git is never
invoked against them); (2) reject the MAIN worktree → 400; (3) realpath
containment on request + each list entry, operating on git's canonical path (+ --);
(4) dirty tree without force → 409 "force required"; (5) locked → 409; (6) errors
classified to fixed safe strings (raw stderr/paths never leaked).
- DELETE /projects/worktree + POST /projects/worktree/prune — both behind
requireAllowedOrigin + worktreeEnabled + audit-logged, mirroring the create route.
- public/projects.ts: ✕ remove button per linked-worktree row (hidden for main/locked)
+ a prune button; force needs an explicit second confirm (no single-click data loss).
Verified: typecheck + build:web clean, worktree tests 108 pass (unit covers
reject-non-registered / reject-main / reject-escape / refuse-dirty-without-force /
clean-remove / force-remove / prune), full suite green at --test-timeout=30000.
Four small, high-delight features that turn passive capture into glanceable signals.
- Sync chip on project cards: ahead/behind vs upstream + last-commit time, folded
into the existing concurrent per-repo metadata pass (git rev-list --count
--left-right @{u}...HEAD + git log -1 --format=%ct; no upstream → undefined, no route).
- Cost budget guard: COST_BUDGET_USD env (0 = off); a per-session one-shot latch
(Session.budgetNotified, cost is monotonic so never re-armed) fires a single push
on threshold crossing in manager.handleStatusLine; the already-broadcast telemetry
frame carries the warn (tg-cost-warn styling derived from costUsd>=budget via
/config/ui — no new ServerMessage). web-push title added to sw-push.js.
- "While you were away" digest: GET /digest?since= → {finished, needsInput, stuck,
totalCostUsd, sessions[]} aggregate over manager.list(); FE banner on reconnect.
- Recent commits per project: src/http/git-log.ts (NUL-delimited git log → CommitInfo[]),
GET /projects/log?path= (isValidGitDir), textContent-inert render in project detail.
All git via execFile (no shell) + validated cwd; new routes read-only; commit
messages rendered via textContent. Verified: typecheck + build:web clean, 1904 pass
at --test-timeout=30000 (two default-5s failures are slow-sandbox real-subprocess
timeout flakes — the known ring-buffer test + a new real-git-clone sync test — not
logic regressions).
Per-project chip: PR state · N checks passing · mergeable — glance from the phone,
re-engage only when it's red, instead of dropping into a terminal for `gh pr checks`.
- src/http/gh.ts (new): single `gh pr view --json number,state,title,url,isDraft,
mergeable,headRefName,baseRefName,statusCheckRollup` (execFile, no shell, cwd =
isValidGitDir repo, timeout + maxBuffer). summarizeChecks rolls the mixed
CheckRun/StatusContext rollup into {total,passing,failing,pending}. Never throws —
degrades to not-installed (ENOENT) / unauthenticated / no-pr / error / disabled.
Cache keyed by repoPath+branch (reuses projectScanTtlMs) with in-flight dedupe.
- src/types.ts: additive PrStatus/PrAvailability/PrCheckSummary; config GH_ENABLED
(default on) + GH_TIMEOUT_MS (8s).
- GET /projects/pr?path= (read-only, isValidGitDir); public/gh-chip.ts render-only
chip mounted in the project detail header (git repos only).
Read-only, host's own authed gh (same trust as the shell). No untrusted argv (only
the validated cwd); gh stdout/token never logged; the attacker-controllable PR title
is rendered inert via textContent (SEC-H4). Verified: typecheck + build:web clean,
1816 pass (gh tests 118). The 1 red is the known real-PTY ring-buffer timeout flake.
The git-diff viewer can now diff the current branch against a base commit-ish
(e.g. main) — review an agent's whole branch from your phone before merging, not
just uncommitted changes. Completes the long-deferred FR-B1.9.
- src/http/diff.ts: getDiff() gains an optional base. Three-layer defense so an
attacker-supplied base never reaches a shell or acts as a git option:
(1) isPlausibleRev() rejects leading '-', '..'/'...' ranges, metachars, control
chars, >250 chars; (2) git rev-parse --verify --quiet --end-of-options
<base>^{commit} — only a resolved 7-64 hex sha is accepted, else empty result;
(3) git diff --no-color <sha>... -- (three-dot = the branch's changes since
divergence, PR-style). execFile, no shell, timeout + maxBuffer bound.
- src/types.ts: additive optional base on DiffResult.
- src/server.ts GET /projects/diff reads ?base (400 on !isPlausibleRev); read-only.
- public/diff.ts: a "compare base" <select> (Working tree + one option per base),
disables Working/Staged tabs in base mode. public/projects.ts derives bases from
the worktree branches ∪ current branch.
Verified: typecheck + build:web clean, 1763 pass (diff tests 87 green). The 1 red
in the plain full run is the pre-existing real-PTY "ring buffer" flake (times out
at default 5s under sandbox load; 27/27 at --test-timeout=30000) — unrelated.
The 'New worktree' form POSTed { repoPath, branch } to /projects/worktree, but
server.ts:706 and the documented contract (FEATURE_WALKAWAY_WORKBENCH FR-B3.1)
read body.path — so every browser worktree-create returned 400 'path and branch
are required' and git worktree add never ran. Send 'path' instead. The existing
worktree-form test had locked in the wrong key (asserted repoPath), which is why
it stayed green while the feature was broken; corrected to assert 'path'.
The flat Projects grid was overwhelming at 50-100 repos. Explored the UX with
4 parallel agents (auto-grouping / manual folders / density-segmentation /
competitive research); all converged on namespace auto-grouping as the primary
fix — the dotted repo names (Billo.Platform.*, Billo.Infrastructure.*) already
encode the hierarchy, so it's a string-split, not a taxonomy the user builds.
Frontend:
- groupProjects(): depth-2 namespace grouping, >=2-member threshold (singletons
fall to "Other"), degrade-to-flat when repos share no prefix, running projects
duplicated into a pinned "Active now" section.
- displayLabel(): cards show the namespace tail (Payment, not
Billo.Platform.Payment); full name in Active/Other.
- Collapsible sticky group headers with an "N active" badge so a collapsed
section never hides running work; search force-expands matching groups.
- public/prefs.ts: server-first load with a localStorage offline mirror, migrates
the legacy per-device proj-favs.
Backend (server-side prefs so favourites + collapse-state follow the user across
devices — localStorage was per-device, which broke the multi-device premise):
- src/http/prefs-store.ts: ~/.web-terminal-prefs.json store (mirrors push-store),
every field bounded + sanitized.
- GET /prefs (read-only) + PUT /prefs (Origin-guarded); UiPrefs type +
PREFS_STORE_PATH config.
Tests: +12 prefs-store, +21 groupProjects/displayLabel. Full suite 1227 passed.
Verified live: grouping renders, collapse persists to the server and survives a
full page reload (cross-device sync proven end-to-end).
The detail page now reads <repo>/CLAUDE.md and shows it in a scrollable
monospace box, with one smart button: "↻ Update" when it exists / "✨ Generate"
when it doesn't. The button opens an interactive Claude session in the repo
running /init (claude "/init") so you review what it writes — reuses the project
launcher, no new backend orchestration, stays a byte-shuttle.
- ProjectDetail += hasClaudeMd / claudeMd; buildProjectDetail reads CLAUDE.md
(truncated 64KB, best-effort, in the existing Promise.all)
- renderProjectDetail: CLAUDE.md section (content box or empty state) + button
- style.css: .proj-section-row / .proj-claudemd-btn / .proj-claudemd
Tests +5 (458): backend read present/absent; frontend content+Update,
empty+Generate, button opens `claude "/init"`. Verified: tsc clean, full suite
green, build OK, curl returns the content, in-browser shows the box + button.
The detail view could kill sessions, but the grid card's session rows were
enter-only. Add a ✕ kill button to each card session row (stopPropagation so it
doesn't also enter the session); makeSessionRow gains an optional onKill,
makeProjectCard an optional onKillSession, and mountProjects wires it to
DELETE /live-sessions/:id followed by a refresh.
Frontend-only. projects-panel tests +1 (51): ✕ present only with the callback,
click kills the right id without entering. Verified in-browser: a card with 2
sessions dropped to 1 after clicking ✕.
Clicking a project's name opens an in-app detail view (back button returns to
the grid) with:
- header: name, path, branch, dirty
- Branch / Worktrees: each `git worktree list` entry (branch or detached@head,
main/current/locked/prunable tags, path) — a single-worktree repo shows its
branch; a multi-worktree repo shows them all
- Active sessions (N): detailed rows (status, devices watching, started-ago)
with Open + Kill
- the Claude/Codex/VS Code launcher row
Backend: src/http/worktrees.ts (parseWorktrees pure + listWorktrees via
execFile, no shell, best-effort); buildProjectDetail(cfg, path, liveSessions)
in projects.ts (validates absolute existing dir, reuses branch/dirty/session
helpers, uncached — detail is on-demand and wants fresh state); read-only
GET /projects/detail?path= (no Origin guard, like /projects; 400 missing /
404 invalid). Types: WorktreeInfo, ProjectDetail.
Frontend: detail view + navigation in projects.ts (grid<->detail), project
name becomes a link, Kill via DELETE /live-sessions/:id.
Tests +21 (452 total): worktree parser, buildProjectDetail (validation,
non-git, session merge, real git-init worktree), renderProjectDetail.
worktrees.ts 100% / projects.ts 93.8% cov. Verified in-browser: opened a
Claude session, then the detail showed its branch+worktree and the live
session with Open/Kill.
Replace each card's "+ start claude here" with a row of three brand-logo
launcher buttons (logo + caption, touch-friendly, tooltips):
- Claude (coral burst) → new terminal tab running `claude`
- Codex (OpenAI mark) → new terminal tab running `codex`
- VS Code (blue ribbon) → opens the repo in VS Code ON THE HOST
VS Code: new guarded POST /open-in-editor runs `<EDITOR_CMD> <path>` (default
`code`) on the host via execFile (no shell); path validated as an existing
absolute dir; Origin guard (CSRF) like the DELETE routes. EDITOR_CMD config added.
Active-session highlight (user request): when a project has a running Claude
session (Claude-hook status != unknown — plain shells/codex stay unknown), the
Claude logo gets a coral ring + tint, with a count badge when more than one.
New: public/icons.ts (simple-icons SVGs, fill=currentColor), src/http/editor.ts.
onOpenProject gains an optional cmd; makeProjectCard exported for tests.
Tests +16 (431 total): editor validation/launch, EDITOR_CMD config, launcher
row (3 buttons, claude/codex commands), and the active-Claude highlight + badge.
Verified: coverage >=80x4, build OK, both typechecks clean; in-browser the 3
logos render with brand colours, and POST /open-in-editor actually launched
VS Code on the host (403 no-Origin / 400 bad-path / 204 valid-dir all correct).
