Copy-only rename (workspace redesign, phase 0). The word a user reads
changes — "Lane" → "Workspace", "Add lane" → "Add workspace" — in both
locales, in agenthub CLI prose and help, in the server's error messages
and in the docs. Every identifier stays: /api/lanes, `agenthub lanes`,
--lane, AGENTHUB_LANE_ID, error codes, tmux names, DB tables, file,
component and i18n key names. docs/LANES.md keeps its name, retitled
"Workspaces (lanes)".
- git (#50): stage-hunk/discard-hunk take an optional `block` — one run of
consecutive +/- lines inside an @@ hunk. `onlyBlock` (server/lib/git-diff.js)
cuts git's fresh hunk down to it, folding the other blocks into the side
being checked; LaneDiffView hangs one review bar per block (unified + split)
and its arrows walk blocks.
- git exclude: entries AgentHub writes for a lane go to the COMMON git dir with
the lane's path prefix (server/lib/git-exclude.js, used by router-apply and
lane-mcp) — a linked worktree's own info/exclude is never read by git, and a
subdir lane has no .git. MCP sync no longer fails with ENOTDIR on a worktree
lane or creates a stray .git in a non-repo lane.
- codex lanes carry no pipeline: codex-ingest mirrors only idle/running,
codex-nudge is removed, agents install writes nothing for codex, the
Workspace hides stage/pipeline/feature pickers/PipelineMap for them, and
every server start clears leftover codex stage data and the old AGENTS.md
stage block.
- Changes panel: a whole file opens for reading and enters the editor on a
click on its text (caret at the clicked line), not automatically.
- macOS: LaunchAgent start-at-login (scripts/launchd-service.js, picked by
scripts/service-manager.js).
- Adds the AgentHub introduction slides and their image-embedding script.
- validateRemoteUrl checks the literal scheme prefix git will receive and
refuses %/backslash in the authority (WHATWG normalises https:/host and
percent-escapes that git reads differently); route test for EBADURL.
- Parent-session scrub also drops AI_AGENT, and GIT_EDITOR when it is
Claude Code's `true`.
- canonicalCwd resolves a not-yet-existing path through its deepest
existing ancestor, so a symlinked parent still yields one lane.
- Note the clock-step ceiling on liveServers' boot-time filter.
- Docs/header wording: the Active runs count is lane-scoped.
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.
Review and the single-file view gain per-hunk Stage and Undo
(stage-hunk / discard-hunk: the hunk is named by its @@ line and
re-matched against a fresh diff, then git apply --cached / -R; undo
needs confirm: true and two clicks). Each review file header stays
pinned while its diff scrolls and carries the file's own
stage/unstage/discard.
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.
