* Create/update the remote stack on sync and fix false "Stack synced"
`gh stack sync` reported "Stack synced" even when it had not created or
updated the stack object on GitHub. After running `gh stack init` to
adopt existing branches and then opening PRs outside the CLI, `gh stack
sync` detected the open PRs and printed "Stack synced" — but no stack had
ever been created on the server.
There were two distinct bugs:
1. Sync never reconciled the remote stack object. `runSync` called
`syncStackPRs`, which only *reads* PR state and links PRs to local
branches; it never called the create/update path. So the branches were
rebased and pushed and the PRs were detected, but the stack on GitHub
was never created.
2. The final message was unconditional. `runSync` always printed "Stack
synced", which is supposed to mean "the stack object on GitHub now
reflects the local stack" — something that can only be true when two or
more open PRs exist and the remote stack was actually created/updated.
Fix
Reconcile the remote stack from sync, and make the closing message reflect
what actually happened.
* cmd/sync.go
- Add a reconciliation step (5b) after PR-state sync: when the stack has
two or more open PRs, link them into a stack on GitHub via the new
`syncRemoteStack` helper. It inspects existing stacks first and:
- short-circuits quietly when a remote stack already lists exactly
these PRs (records the ID, prints "Stack already up to date on
GitHub") so routine syncs don't issue a redundant, misleading
update;
- otherwise delegates to `syncStack` to create a new stack, adopt an
untracked one, or update a partially-formed one.
Sync never opens PRs — that remains `gh stack submit`'s job.
- Replace the unconditional "Stack synced" with a result-driven message:
"Stack synced" when the remote stack object was created/updated/in
sync, otherwise "Branches synced" (fewer than two PRs, stacked PRs
unavailable, a cross-stack divergence, or no GitHub client).
- Update the command's long description to document the stack-object
step and the two possible closing messages.
* cmd/submit.go
- Thread a `synced bool` return through the existing, tested stack
helpers so sync can tell whether the remote stack object now matches
local: `syncStack`, `createNewStack`, and `updateStack` now return
`bool`; `adoptRemoteStack` returns `(handled, synced)`; and
`handleCreate422` returns `bool` (true only when the PRs are already
stacked together). Extract the shared `stackPRNumbers` helper.
- This is additive: submit's single call site ignores the new return
value, so submit's behavior, output, and tests are unchanged. Reusing
these helpers (instead of duplicating the 404/422 handling in sync)
keeps the create/adopt/update logic in one tested place.
Tests
* cmd/sync_test.go — six new cases covering the reconciliation matrix:
- TestSync_CreatesRemoteStackWhenPRsExist: open PRs but no remote stack
-> CreateStack is called and the new ID is persisted to the stack file;
output contains "Stack created on GitHub" and "Stack synced".
- TestSync_AdoptsExistingEqualRemoteStack: a matching remote stack ->
no create/update, ID recorded, "Stack synced".
- TestSync_UpdatesPartialRemoteStack: a subset stack -> UpdateStack with
the full PR list, "Stack synced".
- TestSync_FewerThanTwoPRs_BranchesSynced: one PR -> no stack API calls,
"Branches synced", not "Stack synced".
- TestSync_StacksUnavailable_BranchesSynced: 404 on create -> warns,
"Branches synced".
- TestSync_PRsSpanMultipleStacks_BranchesSynced: PRs across two stacks ->
divergence warning, no create/update, "Branches synced".

* Address PR review: one ListStacks per sync, command-neutral guidance
Two follow-ups from the #156 review (both flagged optional / non-blocking).
1. Remove the redundant ListStacks round-trip on sync's create path.
syncRemoteStack fetched the stack list for its already-up-to-date
short-circuit, then delegated to syncStack -> adoptRemoteStack, which
listed the stacks again — two GETs on the first-sync-create and
membership-changed paths. Refactor adoptRemoteStack into a list-accepting
reconcileUntrackedStack(cfg, client, s, prNumbers, stacks): syncStack now
fetches the list once and passes it down, and syncRemoteStack reuses the
list it already fetched. Net: exactly one ListStacks per sync. This also
drops the (handled, synced) tuple. Submit's behavior is unchanged.
2. Make the divergence / dropped-PR guidance command-neutral. The shared
helper emitted submit-specific wording ("reconcile them before
submitting", "...then `gh stack submit`") that is now reachable from
`gh stack sync`. Reword to "reconcile them first" and drop the trailing
`gh stack submit` so it reads correctly from either command.
Tests: assert exactly one ListStacks on the create path and that the
divergence guidance is not submit-specific.
* increment skill file version
* Simplify sync reconciliation: reuse syncStack instead of a parallel path
Review feedback noted the change felt heavier than the fix warranted.
The weight came from `syncRemoteStack` (cmd/sync.go), a near-duplicate of
submit's `syncStack` — same <2-PR guard, ListStacks, and update/create
dispatch — that existed only to add an "already up to date" short-circuit.
That one optimization is what spawned the second entry point, the
pre-fetched-list threading, and the double-ListStacks it then required.
Collapse it to a single reconciliation path:
- Remove `syncRemoteStack`; `gh stack sync` now calls the shared
`syncStack` directly. One path, one ListStacks per sync.
- Fold `createNewStack` into `reconcileUntrackedStack` (renamed from
`adoptRemoteStack`) so it returns a single `synced bool` instead of a
`(handled, synced)` tuple and owns its own ListStacks again.
- Inline `stackPRNumbers` back into `syncStack` (it was only extracted to
share with the now-removed `syncRemoteStack`).
- Drop the now-unused `strconv`/`github` imports from cmd/sync.go.
Behavior note: a routine re-sync of an already-tracked stack now prints
"Stack updated on GitHub with N PRs" instead of "Stack already up to date
on GitHub". This is accurate (sync does PUT the current state) and matches
submit. The "Stack synced" / "Branches synced" summary is unchanged, and
submit's behavior is unchanged.
* Fork unmerged branches into a new stack when the base stack is fully merged
Once every PR that is officially part of a stack on GitHub has been merged
-- especially after the merged branches are deleted upstream -- you can no
longer add to that stack. A new PR on top would target the trunk directly
instead of chaining onto the merged PRs, so the remote stack's "each PR's
base ref is the previous PR's head ref" invariant no longer holds. On the
next `gh stack submit`, the stack update was rejected and surfaced as a
confusing, dead-end warning:
Failed to update stack on GitHub: Pull requests must form a stack,
where each PR's base ref is the previous PR's head ref
`submit` had no handling for this: `syncStack` always sent the full PR list
(including the merged-and-deleted ones), so the API rejected the broken
chain even though the new PRs had already been created with correct bases.
Fork the survivors into a fresh stack instead of failing. After syncing PR
state and before pushing, `runSubmit` now calls `maybeForkFromMergedBase`:
- It triggers only when every PR officially part of the tracked remote
stack (`s.ID`) has merged. Membership is read from the stacks API, so
open PRs that are not part of the remote stack do not count, and -- this
is the key guard -- a normal partial, bottom-up merge (where the remote
stack still lists an open PR) is left completely untouched. A cheap
pre-check (the local stack must have at least one merged branch) avoids
an extra ListStacks call on the common path.
- The local branches are partitioned: those still in the merged remote
stack stay behind; everything else (new branches, plus open PRs that were
never part of that remote stack) is lifted into a brand-new stack rooted
at the original trunk, with an empty remote ID. The bottom survivor is
re-based onto the trunk.
- `runSubmit` continues with the new stack, so the push loop, PR creation,
and `syncStack` all operate on it; the empty ID routes `syncStack` through
the adopt/create path and a fresh stack is created on GitHub.
- The original, fully merged stack is left untouched on GitHub. Locally it
is kept as a record only if at least one of its branches still exists in
the working copy; otherwise it is dropped. No data is lost -- those PRs
are already merged on GitHub.
To restructure the stack file safely, add `StackFile.IndexOfStack`, which
locates a stack by pointer identity so the fork can capture what it needs
before `AddStack`/`RemoveStack` reallocate the underlying slice.
Also soften the partial-merge case that does not fork: when an `UpdateStack`
call fails with the "must form a stack" 422 and the stack still contains
merged branches, report it as an informational note (the unmerged PRs were
pushed and re-based onto the trunk) rather than a scary failure warning.
Scope is limited to `submit`. `add` and `checkout` keep their existing
"refuse and suggest `gh stack init`" behavior on fully merged stacks.
Tests:
- cmd/submit_test.go: TestSubmit_ForksWhenRemoteStackFullyMerged covers both
disposition variants (the old stack is removed when its merged branches
are gone locally, kept when they still exist) and asserts that only the
new branches are pushed, the fork message is printed, a fresh stack is
created, and the local stack file is split into two stacks.
TestSubmit_NoForkWhenRemoteStackHasOpenPR verifies the everyday bottom-up
merge is not forked and that the broken-chain 422 is reported calmly.
TestUpdateStack_BrokenChainAfterMerge checks the calm-vs-warn branch.
- internal/stack/stack_test.go: TestIndexOfStack covers identity lookup and
the not-found case.
Docs: README, the CLI reference, the stacked-PRs guide, the FAQ, and the
agent SKILL.md note that submitting onto a fully merged stack starts a new
stack rooted at the trunk.
* Handle fully merged stacks gracefully in the view and modify TUIs
Merged branches (and their PRs) are not selectable, so once an entire stack
has landed there is nothing to act on -- yet the TUIs did not reflect that:
- `gh stack view` still drew a highlighted cursor on the top branch even
though it could not be selected. Navigation, checkout, and the per-branch
toggles all silently did nothing, with no indication of why.
- `gh stack modify` opened its full editor on a stack with nothing left to
restructure, instead of short-circuiting like `gh stack submit` does when
there is nothing to submit.
Reflect the "nothing actionable" state in both TUIs.
View (internal/tui/stackview/model.go):
- Hide the cursor when every branch is merged. `New` now starts the cursor
at -1 and only lands it on the current or first non-merged branch; when
none exists the cursor stays hidden, so no row is rendered as focused. The
existing `m.cursor >= 0` guards and merged-skipping `moveCursor` already
make every cursor action a no-op in that state, and mouse-wheel scrolling
still works for tall merged stacks.
- Dim the shortcuts that depend on the cursor. `buildHeaderConfig` marks
navigate, commits, files, open PR, and checkout as `Disabled` (rendered
gray via the existing ShortcutEntry.Disabled styling) when all branches
are merged, leaving only `q quit` active.
Modify (cmd/modify.go):
- Short-circuit before opening the TUI. After preconditions pass and PR
state is synced, `runModify` now returns early when the stack is fully
merged, printing "All branches in this stack have been merged" and
pointing at `gh stack init`, exiting cleanly (exit 0) like submit's
"nothing to submit" path. The linearity and merge-queue precondition
checks already skip merged branches, so they do not fire spuriously.
Tests:
- internal/tui/stackview/model_test.go: the cursor is hidden (-1) when all
branches are merged; up/down/enter do not move it or trigger a checkout;
View renders without panicking on a hidden cursor; buildHeaderConfig
disables every cursor-dependent shortcut (and only those) when all merged,
and leaves them all enabled when active branches remain.
- cmd/modify_test.go: runModify short-circuits on a fully merged stack,
printing the message and returning no error without launching the TUI.
* Make the TUIs adapt to light and dark terminal backgrounds
The submit, view, and modify TUIs were tuned for dark terminals. On light
or solarized-light backgrounds the result was hard to read and inverted:
primary text used ANSI white (invisible on white), dim chrome used light
grays (too faint), and accents used bright cyan (low contrast) — so
"active" things looked lighter than "disabled" ones.
Introduce a centralized, background-aware color palette and migrate all
three TUIs to it:
- internal/tui/shared/theme.go: a semantic palette of lipgloss.AdaptiveColor
values (primary/muted/faint text, chrome/border, accent, PR-state colors,
badge backgrounds, row shade, button, switch). lipgloss resolves the
light/dark variant per render from the terminal background, which Bubble
Tea detects at startup; terminals that don't report it fall back to dark,
preserving the original look.
- Replace every hardcoded ANSI color in shared/, submitview/, and
modifyview/ with palette roles. The four pre-rendered status icons now
render at use-time so their adaptive colors resolve correctly. The submit
markdown preview picks glamour's light or dark style from the detected
background.
- GH_STACK_THEME=auto|light|dark forces the palette for terminals that
mis-detect (some SSH/tmux setups); wired via the root command's
PersistentPreRun before any render. Documented in the README and CLI docs.
Neutral text/chrome use truecolor hex (GitHub Primer-inspired) for
predictability across themes, including solarized which repurposes ANSI
8-15; lipgloss downsamples on terminals without truecolor.
Tests verify the palette resolves differently for light vs dark and that
GH_STACK_THEME is honored.
* Apply background-aware colors to all command output
Background detection and the GH_STACK_THEME override (added for the TUIs)
only affected the interactive screens. Plain command output -- status
messages and interactive prompts -- went through the mgutz/ansi library
with fixed ANSI palette names (green/red/yellow/cyan/...), so it never
adapted to the terminal background and could read poorly on light or
solarized themes.
Unify everything on the same adaptive palette so all colors react to the
detected background and to GH_STACK_THEME.
- Extract internal/theme, a foundational package with no internal
dependencies, that owns:
- the background-aware lipgloss.AdaptiveColor palette (moved out of
internal/tui/shared),
- ApplyOverride(), the GH_STACK_THEME=auto|light|dark logic, and
- non-TUI colorizers (Success/Error/Warning/Blue/Magenta/Cyan/Gray/
Bold) plus FgSeqs(), which returns the raw start/reset escapes used
to color the user's echoed prompt input.
- internal/tui/shared/theme.go now re-exports the palette, so the TUI code
keeps referring to shared.ColorX unchanged.
- internal/config/config.go wires the Config.Color* funcs to the theme
colorizers and drops mgutz/ansi (now an indirect dependency only).
- cmd/utils.go colors the prompt icon and echoed input via theme.
- cmd/root.go calls theme.ApplyOverride() in PersistentPreRun.
Detection adds no cost: because the command package imports Bubble Tea,
its init() already triggers (and caches) the terminal background query for
every command, so the non-TUI colorizers just read the cached value.
Terminals that don't answer the query fall back to the dark palette;
GH_STACK_THEME=light|dark forces it. Colors are truecolor on capable
terminals and downsample to the nearest ANSI color elsewhere.
Tests: internal/theme covers palette adaptiveness, ApplyOverride, the
colorizers, and FgSeqs; a new internal/config test verifies the wired-up
Config.Color* funcs adapt to the background when color is enabled.
Docs: README and the CLI reference note that GH_STACK_THEME now controls
all colored output, not just the interactive screens.
No behavior change beyond colors.
* Add submitview data model and PR draft override plumbing
Introduce the internal/tui/submitview package that will back the new
interactive `gh stack submit` TUI, and wire its per-PR override contract
into the submit command without changing current behavior.
- submitview: BranchState model (NEW/OPEN/DRAFT/QUEUED/MERGED/CLOSED) with
selectability/editability rules, SubmitNode UI state with edit detection,
PRDraft override type, state derivation, title/description prefill, and
state-badge/panel/tab styles.
- submit: refactor ensurePR/createPR to accept an optional per-branch
override map (title/body/draft/include); deselected NEW branches are
pushed but get no PR.
The override map is nil on the --auto / non-interactive path, so the
agent-compat contract is unchanged. Fully unit tested.
* Add single-screen submit TUI
Introduce an interactive, single-screen editor for `gh stack submit`,
built on Bubble Tea and Lip Gloss.
The left panel renders the stack as a connected tree down to the trunk.
Every branch without a PR is included by default; deselect one with its
checkbox or `^x`. Because each PR builds on the branch below it,
deselecting a branch also deselects the ones stacked above it, and
re-including a branch re-includes the ones below it that it depends on.
The cursor uses its own cyan accent so it reads distinctly from the green
new/included color; existing PRs are shown dimmed with a no-entry glyph.
The right panel edits the focused branch's PR in web-create-PR order: a
header with the branch name and an include chip ("Creating PR" /
"Skipped"), the title, a scrollable description (Glamour markdown preview
and $EDITOR escape, with a scrollbar and mouse click-to-position), and a
ready to draft segmented toggle (defaulting to ready). A footer strip
shows the PR progress, the next branch, and the editor hints. Skipping a
branch dims its body; branches that already have a PR show a read-only
card linking to the PR.
It shares the gh-stack header (art, title, stack info, and keyboard
shortcuts) with `gh stack view` and `gh stack modify` for a unified look.
Submit every included PR at once with Ctrl+S. Full keyboard and mouse
support throughout.
* Wire the single-screen submit TUI into `gh stack submit`
Launch the submit editor from `gh stack submit` in interactive terminals,
collecting per-branch PR drafts and applying them in a single batch. In
non-interactive terminals or with --auto, fall back to auto-generated
titles and skip the editor. Update the README and CLI reference to
describe the single-screen flow.
* Use the API PR title/body for existing PRs and fix new-PR defaults
For existing PRs, the submit TUI showed a commit/template-derived draft
instead of the pull request's real title and body. Fetch the actual title
and body and render them in the read-only card:
- open/draft/queued (tracked) and adopted-open PRs now carry title/body
through the existing batch sync (added the fields to the GraphQL queries
and PRDetails — no extra round trips), and
- merged branches (which skip the live refresh) are filled in by a targeted
enrichment step run only when the submit TUI opens.
Also align the new-PR defaults with the non-TUI submit's defaultPRTitleBody:
- Title: the commit subject only when the branch has exactly one commit,
otherwise the humanized branch name (was: the oldest commit's subject even
for multi-commit branches).
- Description: the PR template, else the single commit's body, else empty
(removed the bulleted commit-subject list for multi-commit branches).
* Stop mouse wheel from leaking escape characters into form fields
Scrolling the mouse wheel while a title or description field was focused
could insert stray characters such as "[<65;54;51M" into the field. The
submit TUI ran the Bubble Tea program with WithMouseAllMotion (mode 1003),
which reports an event on every pointer move. During a wheel scroll that
floods the input stream, and under that volume Bubble Tea splits an SGR
mouse escape sequence ("\x1b[<Cb;Cx;Cy(M|m)") across input reads; the
leftover bytes of a partially-parsed sequence are then emitted as key
runes and inserted into the focused text input.
Two changes fix this:
- Switch to WithMouseCellMotion (mode 1002), which reports clicks, drag,
and wheel but not idle pointer motion. That removes the per-move input
flood, so under a real terminal's reads (up to 256 bytes) the only
fragment that still surfaces is a single, clean burst at each wheel
notch boundary. The TUI never used idle-hover for rendering, so
cell-motion loses nothing.
- Drop any leaked fragments before they reach a field. A split SGR mouse
sequence surfaces as an Alt+"[" (the consumed "\x1b[") followed by
body fragments ("<65;54;5", "1M"), or occasionally the whole body in
one run ("[<65;54;51M"). consumeLeakedMouseKey recognises the start,
swallows the body up to its "M"/"m" terminator, and bails out the
moment a rune does not fit an SGR body, so ordinary typing (including
"<", ";", digits, "M") and bracketed pastes are never eaten.
Tests cover every split point of an SGR sequence, single-run tails,
preserved real typing, a stray Alt+"[", bracketed paste, and that wheel
events never modify the focused field. Verified end-to-end by feeding
1,500 wheel sequences through the real parser under terminal-sized reads
and confirming the field stays empty.
* Re-enable mouse tracking after the external editor closes
Opening the description in $EDITOR with ^e and then quitting left the
mouse unresponsive: clicks and wheel scrolling stopped working while
keyboard navigation still did.
The editor is launched with tea.ExecProcess, which releases the terminal
before running the command and calls Bubble Tea's RestoreTerminal when it
returns. RestoreTerminal re-enables the alt-screen, bracketed paste, and
focus reporting, but it does not re-enable mouse tracking. The editor
(e.g. vim) disables mouse reporting on exit, so once control returns to
the TUI the terminal no longer emits mouse events.
Re-arm mouse mode when the editor-finished message arrives by batching
tea.EnableMouseCellMotion with the handler's command. That re-enables
cell-motion and SGR mouse reporting, matching the WithMouseCellMotion
option the program starts with, on every editor-return path (success or
error).
* dead code cleanup
* support mouse input to move cursor in title field
* use textArea for title to support word wrap for long inputs
* Accept PR URLs in link and checkout commands
Add support for GitHub PR URLs (e.g. https://github.com/owner/repo/pull/42)
as arguments to `gh stack link` and `gh stack checkout`, in addition to
the existing PR number and branch name support.
For `link`: PR URLs are parsed in findExistingPR before the numeric check.
Unlike numeric args, if a URL-extracted PR number doesn't exist, the command
errors immediately rather than falling through to branch name lookup (since
a URL can never be a valid branch name).
For `checkout`: PR URLs are parsed in runCheckout before the numeric check,
routing to resolveNumericTarget which supports both local and remote API
fallback — same behavior as passing a PR number directly.

* Add `gh stack trunk` navigation command
Add a new navigation command that checks out the trunk branch of the
current stack.
The command is stack-aware: it requires the user to be on a branch that
is part of a stack, loads the stack metadata, and checks out `s.Trunk.Branch`.
If the user is already on the trunk branch, it prints a message and exits
without calling git checkout.
New files:
- cmd/trunk.go: TrunkCmd (cobra command) + runTrunk implementation
- cmd/trunk_test.go: 7 test cases covering happy path, already on
trunk, from top of stack, not in a stack, checkout failure, custom
trunk branch name, and positional argument rejection
Modified files:
- cmd/root.go: register TrunkCmd in the "nav" command group
- README.md: add `gh stack trunk` to the Navigation section
- docs/src/content/docs/reference/cli.md: add `gh stack trunk`
reference section
* address review comments
* increment skill version
* add insert branch operation to modify TUI
Add `i` (insert below) and `I` (insert above) key bindings to the
interactive modify view, allowing users to insert new empty branches
into an existing stack. This follows Vim-inspired semantics where
lowercase `i` inserts below the cursor and uppercase `I` inserts above.
## TUI behavior
When the user presses `i` or `I`, the TUI enters an insert input mode
(similar to rename mode) where they type a new branch name. The input
is validated against git ref naming rules, local branch uniqueness, and
in-stack name collisions. On confirm, a placeholder node is inserted at
the correct position in the branch list with a green "✚ insert"
annotation badge and green connector styling.
Insert is a structure operation — it works alongside fold, rename, and
drop, but is mutually exclusive with reorder (consistent with existing
mode exclusivity rules). Undo (`z`) removes the inserted node cleanly.
## Apply engine
At apply time (Step 2 in the pipeline, between renames and folds), the
engine creates the new git branch at the parent branch's tip via
`git.CreateBranch` and inserts a `BranchRef` into the stack metadata at
the correct position. If the insertion changes the base of a branch
that has an open PR, `affectsPRs` is set to trigger a required
`gh stack submit` afterward.
## Header shortcut updates
- Combined the fold shortcuts into a single line: `d/u - fold down/up`
- Added insert shortcuts on their own line: `i/I - insert below/above`
- Reordered fold references throughout to list "down" before "up" for
consistency with the insert shortcut ordering
## Files changed
- types.go: ActionInsertBelow/ActionInsertAbove types, IsInserted field,
InsertedBranches in ApplyResult
- model.go: key bindings, insert input mode, undo, mode exclusivity,
annotation, styling, header shortcuts, effective-index tracking to
prevent false reorder detection when inserts shift node positions
- styles.go: green insert badge/branch/connector styles
- status.go: insert counting in pending change summary
- help.go: new "Insert below / above" section, reordered fold heading
- apply.go: BuildPlan and ApplyPlan handle insert actions
- modify.go: updated command description and success summary
- README.md: updated keybindings table
## Test coverage
- 16 new TUI tests: insert below/above, top/bottom edges, undo, mode
exclusivity, merged branch guard, cancel/empty input, duplicate name
validation, pending summary counting, annotation rendering, mixed
operations with drop/fold, apply acceptance
- 4 new apply tests: BuildPlan produces correct insert actions,
ApplyPlan creates branches and updates stack metadata, insert at
stack start uses trunk as parent, affectsPRs triggered when inserting
before a branch with an open PR
* update add error msg to direct users to modify for inserting branches
* docs updates
* fix insert branch bugs in modify TUI
Fix three bugs with the insert branch feature in the modify TUI, and
adjust rename behavior on inserted nodes.
## Bug 1: False "moved" annotations on existing branches
After inserting a branch, all branches below the insertion point
displayed "↕ moved 1 layer down" annotations. This happened because
`nodeAnnotation` and `toNodeData` compared each node's
`OriginalPosition` against its raw array index, which gets shifted
when an inserted node is added to the slice.
Fix: introduce an `effectiveIdx` parameter that counts only
non-inserted nodes, so position comparisons reflect the original
ordering. The View loop computes effective indices by incrementing
only for non-inserted nodes and passes them to the rendering
functions.
## Bug 2: Header branch count inflated by staged inserts
The branch count in the header ("N branches") included inserted
placeholder nodes, making it appear as though the stack had grown
before changes were applied.
Fix: `buildHeaderConfig` now excludes `IsInserted` nodes from the
branch count. The count reflects only the original branches in the
stack.
## Bug 3: Operations allowed on inserted placeholder nodes
Inserted nodes could be folded into other branches, which makes no
sense for a placeholder with no commits. Additionally, the "last
branch" guard counted inserted nodes as active, allowing users to
drop all original branches and bypass the empty-stack check.
Fix:
- `fold()` rejects inserted nodes with a descriptive error message.
- `toggleDrop()` on an inserted node removes it entirely and pops
the original insert action from the undo stack (clean cancellation
rather than a separate undo entry).
- All three "active branch" guards (`toggleDrop`, `fold`, `tryApply`)
now exclude `IsInserted` nodes, ensuring at least one original
branch always remains in the stack.
## Rename on inserted branches
Instead of blocking renames on inserted nodes, pressing `r` now
enters rename mode and updates the insert action's name in place.
The node's `Ref.Branch` and `PendingAction.NewName` are both updated
directly — no separate rename action is created in the undo stack.
This lets users fix a typo without having to drop and re-insert.
## Tests added
- `TestInsertDoesNotShowMovedAnnotation` — verifies no false move
annotations appear on existing branches after an insert
- `TestBranchCountExcludesInserts` — verifies header count stays
stable after insert
- `TestCannotFoldInsertedBranch` — verifies fold is blocked
- `TestCannotRenameInsertedBranch` — verifies rename updates the
insert name in place
- `TestDropInsertedBranchRemovesIt` — verifies drop removes the node
- `TestDropInsertedBranchCanBeUndone` — verifies drop pops the
original insert from the undo stack
- `TestCannotDropAllOriginalBranchesWithInsert` — verifies the
empty-stack guard excludes inserted nodes
* ensure cannot fold into an inserted branch
* rm dead code
* delete inserted branches during abort
* Add --committer-date-is-author-date flag to gh stack rebase
Introduce an opt-in `--committer-date-is-author-date` flag (with
`--preserve-dates` alias) for `gh stack rebase`. The flag is passed
through to every underlying `git rebase` invocation in the cascade,
keeping committer dates equal to author dates so that identical content
rebased onto an identical parent produces stable SHAs. This reduces
spurious force-push notifications and noisy review timelines, especially
in deep stacks where bottom branches get re-rebased on every merge.
Git layer changes:
- Add `RebaseOpts` struct with `CommitterDateIsAuthorDate` field to
`internal/git/gitops.go`
- Update `Ops` interface, `defaultOps`, public wrappers, and
`rebaseContinueOnce`/`tryAutoResolveRebase` helpers to accept and
forward the flag
- Update `MockOps` to match the new signatures
Command layer changes:
- Register `--committer-date-is-author-date` and `--preserve-dates`
flags on the cobra command in `cmd/rebase.go`
- Add `CommitterDateIsAuthorDate` to `cascadeRebaseOpts` and thread it
to all `git.Rebase`/`git.RebaseOnto` calls in `cmd/utils.go`
- Persist the flag in `rebaseState` JSON so `--continue` resumes with
the same behavior; pass it to `RebaseContinue` and subsequent cascade
calls
- Update `internal/modify/apply.go` callers to pass zero-value
`RebaseOpts{}`
Tests:
- Update all existing mock signatures in rebase, sync, and modify tests
- Add tests for flag passthrough, `--preserve-dates` alias, state
round-trip, `--continue` flag restoration, and conflict state
persistence
Docs:
- Update flag tables and examples in README.md and
docs/src/content/docs/reference/cli.md

* Fix 4 bugs from code review
Bug 1: Move RevParseMap error check before using originalRefs.
The error from git.RevParseMap() was deferred past iteration of
originalRefs, which could panic on a nil map.
Bug 2: Differentiate cherry-pick vs rebase conflicts in modify.
Cherry-pick conflicts don't save state as 'conflict' phase, so
--continue won't work. Now prints --abort-only instructions for
cherry-pick conflicts.
Bug 3: Unwind now cleans up branches created by renames.
After restoring snapshot branches, Unwind deletes renamed branch
names that don't belong to the original snapshot.
Bug 4: Simplify push message in submit command.
Changed from 'Pushing N branches to remote...' to 'Pushing to
remote...' since individual branches may fail.

* Fix 7 nit issues from code review
11: Add named constants for phase strings (PhaseApplying, PhaseConflict,
PhasePendingSubmit) in state.go; replace remaining raw literals in
state.go CheckStateGuard.
14: Fix bottomLines comment mismatch — listed 3 items but value is 2.
15: Extract magic number 88 to MinWidthForArt constant in header.go.
16: Remove unused stackview import anchor in model.go — the import
is used via types.go where BranchNode is embedded.
17: Simplify CheckStackLinearity parent resolution — ActiveBaseBranch
already handles skipping merged branches.
18: Fix rename undo matching any rename — add NewName check so only
the specific rename being undone is matched.
20: Add TestUndoRename and TestUndoRename_DoesNotAffectOtherRenames
to validate rename undo behavior.

* Make cherry-pick conflicts recoverable via --continue
Previously, cherry-pick conflicts during fold-down operations could only
be resolved with --abort. Now they save full conflict state (phase,
conflict type, fold branch/target, remaining branches) to the state file,
enabling recovery via 'gh stack modify --continue'.
Changes:
- Add ConflictType field to StateFile (rebase or cherry_pick)
- Add FoldBranch/FoldTarget fields for cherry-pick context
- Add CherryPickContinue to git package (cherry-pick --continue)
- Save cherry-pick conflict state in ApplyPlan with remaining branches
- ContinueApply handles both rebase and cherry-pick conflicts
- Unified conflict messaging in cmd/modify.go (both types show --continue)
- Updated test to verify cherry-pick conflict state is saved correctly
