What broke: a lane on a fresh `git init` repo had no working git surface.
`statusCounts` ran `rev-parse --short HEAD` unguarded, so `gitFacts` threw
and `GET /api/lanes/:id/git` answered `{available:false}` — the Changes
panel showed no header, and `commit`/`switch` 500'd through `isDirty`.
Add lane in Worktree mode accepted such a repo and left a `failed` row
behind, and a repo with commits but no remote had a permanently disabled
Push with no way to give it one short of a terminal.
What changed:
- worktree.js: an unborn HEAD is a normal state. `statusCounts` reports
`head: null`; `gitFacts` reads the branch via `symbolic-ref`, an empty
subject, and a new `unborn` field.
- git-ops.js: an 11th write, `publish` — `remote add origin -- <url>` then
`push -u origin HEAD`, only with a commit (ENOCOMMITS) and NO remote at
all (EREMOTEEXISTS, so it never re-points one), the url allowlisted by
`validateRemoteUrl` (https without userinfo, ssh://, scp-like; refuses
local paths, file://, ext::, fd::, git://, http://, leading `-`:
EBADURL), and `origin` removed again when the push fails.
- POST /api/lanes/worktree answers 400 EEMPTYREPO for a repo with no
commits instead of creating a row that can only fail.
- LaneGitBar: unborn repos show "no commits yet" and a commit-first hint;
no remote offers Publish… with an inline URL box; a remote but no
upstream relabels Push as "Publish branch". AddLaneModal disables Add
on an empty repo and offers "Use as a Repo lane".
- The two tests that used an unborn repo to force a provisioning failure
now use a `feat` ref clash, since that repo is refused up front.
- CLAUDE.md rule reworded to "the boring eleven" with publish's guards;
docs/API.md, docs/LANES.md, ARCHITECTURE.md, server/README.md, openapi.
Part A — a fetch/pull/push against a remote that needs a login no longer
dies on "terminal prompts disabled": the server answers 409 EGITAUTH with
the host, the git bar asks for a username + password/access token and
resends the same action. AgentHub keeps its OWN credential store
(<CLAUDE_HOME>/agenthub-git-credentials/, 0700/0600), one login per host,
shared by every user of the install, managed from Settings -> Git
credentials. A login is only sent to one of the repo's own remote hosts,
saved only after git accepted it, never returned by any route, and reaches
git through an exclusive credential helper (never argv).
Part B — merge a branch (or the diverged upstream) from the git bar; a
merge that stops on conflicts lists them in the Changes panel with Keep
mine / Take theirs / Mark resolved, then Complete merge or Abort merge
(confirm gate). Clean tree, repo-root lane and an existing ref only;
pull/switch/hunk actions are blocked mid-merge; staging a conflicted file
with markers left is refused. Rebase/reset/stash stay out.
- The run form's prompt box offers suggestions again: `/` lists the run
cwd's project and user commands and skills plus the CLI built-ins
(claude lanes only), `@` lists files under the cwd; Enter picks while
the list is open and sends otherwise. The 2f39f4e rewrite had left a
bare textarea that ignored both.
- Active runs lists only the current lane's runs and external sessions
(sessions matched to the lane by longest path-boundary cwd), instead of
every lane's.
- The Changes panel's git line and its actions are one compact row in one
card, and the mode/range toolbar is one wrapping row.
- The lane card hides itself when it has nothing to show, instead of
leaving an empty frame where the git row used to be.
- The branch line, the uncommitted-files hover panel and the git action
row (fetch/pull/push/branch) move from the lane card to the top of the
Changes panel (new LaneGitHeader.tsx); the card has no git row now.
- Header and panel share one git-facts read: stage/unstage/discard/commit
and Refresh re-read it, and a git bar action re-reads the diff, the
history and the file tree.
- The git bar no longer commits: the panel's staged-only box is the one
commit path. Orphaned gitBar.commit*/cancel strings removed (en, vi).
- "New lane here" is wired from Workspace to the panel.
Server (git-diff.js, git-ops.js, worktree.js, routes/lanes.js):
- Every lane git call runs with GIT_LITERAL_PATHSPECS=1 and -z porcelain, so a
file name is a file name, never a glob, and odd names parse correctly.
- A lane that is a subdirectory of its repo sees and acts on ONLY its own
paths (reads, stage/unstage/discard/commit, and gitFacts.files).
- Any file named settings.local.json (the lane's router API key) is refused as
403 ESECRET on disk (symlinks resolved) and at every committed rev.
- commit refuses with 400 ESTAGEDOUTSIDE while anything outside the lane is
staged (checked with --no-renames, so a move into the lane is caught).
- push resolves its remote (upstream → only remote → origin), else 400
ENOREMOTE; unstaging a rename unstages both halves.
- Git writes serialize on the repo's git dir, not the lane id, so two lanes on
one index cannot collide on index.lock.
- git refusing an action (a numeric exit status) answers 409 EGIT with git's
stderr instead of a 500 carrying a numeric code; one shared parseNumstat.
Client:
- Changes panel: no stale answer from a previous lane or an older quick-open
query repaints the panel; discard disarms on lane switch; Enter on a file
path opens it instead of folding; bounded tree expand-all.
- Large diffs (> 500 rows) render only the visible rows, with stable width
and in-sync split columns; mirrored split scroll is clamped.
- Git bar: no "in sync" without counts, a clear no-remote message, branch list
re-read after a switch, and no previous-lane facts after a lane switch.
- Tooltips no longer flicker or close on unrelated scrolls.
- Changes card beside lane detail with five modes: Files tree, overview,
Review (whole diff, per-file collapse), single file, commit history.
- LaneDiffView: unified / side-by-side with independent scroll on both axes
and mirrored scrollLeft, expand/collapse context, intra-line emphasis.
- Staged-only commit box; git actions (fetch/pull/push/stage/unstage/
discard/commit/switch/branch-create/branch-delete) guarded in git-ops.js.
- Server: git-diff.js + git-ops.js behind GET /api/lanes/:id/git/* and
POST /api/lanes/:id/git/:action; gitFacts gains upstream/ahead/behind.
- Add lane: new/existing branch, current branch, worktree list, prefill
from the git bar's "New lane here"; /api/run/cwds gains a repo kind.
- GlobalTooltip upgrades every native title into a themed anchored bubble;
chart/info popovers use theme tokens.
