Steps, in order: + +1. **Fetch** from the remote. +2. **Reconcile with the GitHub stack.** PRs added to the stack on github.com are pulled down and + appended locally. On divergence, aborts when non-interactive (see `troubleshooting.md`). +3. **Fast-forward the trunk.** Skipped when already current; warns when diverged. +4. **Cascade rebase when needed.** This runs if the trunk moved, a stack branch was fast-forwarded + from its remote, or a branch no longer contains its expected parent. Merged PRs are handled + automatically. On conflict, **all branches are restored** to their pre-rebase state and the + command exits **3**. +5. **Push** all active branches, atomically. +6. **Refresh PR state** from GitHub. +7. **Sync the stack object** — link open PRs into a stack, additively. Only when two or more PRs + exist. `sync` never opens PRs; that is `submit`. +8. **Prune** local branches for merged PRs, only when `--prune` is passed in a non-interactive + environment. + +## rebase + +Pulls from the remote and cascade-rebases. Use it when `sync` reported a conflict or when you need +to rebase only part of the stack. + +- `--upstack` rebases from the current branch to the top. This is what you run after editing a + lower layer. +- `--downstack` rebases from the trunk to the current branch. +- `--no-trunk` skips fetching and the trunk rebase entirely, aligning stack branches with each + other only. +- `--continue` after staging resolutions; `--abort` restores every branch. +- A merged PR is detected automatically and replayed with `--onto` against the correct target, so a + squash-merged parent does not produce spurious conflicts. +- Starting a rebase while one is in progress exits **7**. + +## view + +- `--json` writes the machine-readable payload to stdout. Its schema is in `SKILL.md`. +- Bare `view` opens a full-screen TUI when stdout is a TTY, and prints static text when piped. +- `--short` prints a compact one-line-per-branch summary and never opens the TUI, but it is + formatted for humans; parse `--json` instead. +- `view` refreshes PR state from GitHub as a side effect, best-effort — it does not fail when the + API is unreachable. + +## checkout + +Accepts a stack number, PR number, PR URL, or branch name. + +- A bare number resolves as a **stack number first**, then a PR number, then a branch name. +- Stack numbers, PR numbers, and PR URLs fetch from GitHub, pull the branches down, and set the + stack up locally. +- If a local stack already exists over those branches with a different composition, `checkout` + cannot be forced past it. Run `gh stack unstack --local` first, then retry. +- `checkout` has no flags. It relies on `remote.pushDefault` when several remotes exist. + +## unstack + +Removes the stack **grouping** only. It never deletes pull requests or branches. + +- With no argument it targets the active stack — the one containing the current branch — removing + it on GitHub and locally. +- With a stack number it works from anywhere in the repository, tracked locally or not, via the API. + Local tracking is also removed when present. +- `--local` removes local tracking only and never contacts GitHub. Combining `--local` with a stack + number that is not tracked locally is an error. +- An unknown stack number exits **2**. + +## merge + +- Scope with an argument: pass a PR number to merge that PR and every unmerged PR below it in the + stack, or pass a stack number to merge every unmerged PR in that stack. +- **All-or-nothing.** If any PR in that exact merge set cannot be merged, none are, and the reason + is reported. +- The method comes from `--squash`, `--rebase`, `--merge`, or `--merge-method `. Without + one, the last-used method is reused. +- Only basic PR state is checked before merging: open and not a draft. Bypassing merge requirements + is not supported for stacks. +- **A merge queue on the base branch overrides everything.** The stack is added to the queue rather + than merged; the queue chooses the method and any method flag you passed is ignored with a + warning. Queued PRs are submitted together but land as the queue processes them, so they may merge + in separate groups rather than all at once. +- `gh pr merge` cannot merge a stack. Always use `gh stack merge`. + +## Navigation + +`up`, `down`, `top`, `bottom`, and `trunk` are always non-interactive. `up` and `down` accept a +count (`gh stack up 3`).

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the bash helpers with stdlib-only Python scripts that emit fenced JSON envelopes per the skills/agents guidelines, and add a pytest suite. - scripts/gh_stack_shared.py: git/gh wrappers, ancestry/branch queries, envelope - scripts/gh_stack_preflight.py: read-only environment gate; per-check fix; exit 0/1 - scripts/gh_stack_convert.py: rebase --onto chaining, idempotent, exit 3 on first conflict with layer+files, exit 5 on invalid input; gh stack init on success - scripts/sc_shared.py synced per repo convention for artifacts.scripts - tests/: 32 cases — mocked-subprocess unit tests for shared, preflight, and convert, plus a real-git integration test (conflict -> resume -> linear chain) - SKILL.md, playbook, README, CHANGELOG, manifest, registries updated to the Python entry points;

tests, and playbooks per review Address all 13 major findings from the four-dimension review pass: - convert: refuse dirty tree / in-progress rebase / diverged local branches; fast-forward branches strictly behind their remote; reject trunk-as-layer; mirror preflight's multi-remote guard; distinguish non-conflict rebase failures (CONVERT.REBASE_FAILED) from conflicts; surface failed checkout in init_stack instead of false existing_stack_kept - convert: record per-layer pre-rebase tips in transient refs/sc-gh-stack/orig/* so a layer branched off the layer below rebases with an exact upstream bound (no duplicated lower-layer commits), surviving conflict-resume re-runs; skip check now also rejects trunk-merge commits so layers stay linear - tests: isolate integration fixture from global/system git config; exercise PR-number resolution through a real gh stub; bind _healthy_env overrides once; new coverage for dependent layers, trunk-merge linearisation, stale/diverged remotes, mid-rebase re-run, and STACK.INIT_FAILED - docs: Step 1 verifies python3; script-location fallback with an explicit do-not-hand-roll rule; dependency-ordering procedure for many PRs; submit partial-failure recovery via troubleshooting.md; no-arg gh stack merge --yes; conflict-loop, exit-9 state, and stack_init failure guidance Co-Authored-By: Claude Fable 5 ---

convert: remote-freshness/divergence guard now runs for EVERY layer before the skip test, so an already-chained branch whose remote gained commits can no longer be silently skipped and force-pushed away at submit; adopted layers are judged against their recorded pre-rebase tip instead of rewritten history - convert: conversion identity stored in local config (sc-gh-stack.conversion); starting a conversion with a different trunk/layer list deletes every refs/sc-gh-stack/orig/* ref, so bookkeeping abandoned mid-conversion can never suppress guards or poison upstream bounds later; refs are kept after success (that is what keeps pre-submit re-runs idempotent) - convert: orig refs recorded from refs/heads/ (a same-named tag can no longer win disambiguation); a stopped rebase with zero unmerged paths (rerere autoUpdate) is reported as a resumable conflict, not CONVERT.REBASE_FAILED; explicit GIT.NOT_A_REPO guard; untracked files no longer count as dirty; merge-only layers flattened to empty report action rebased_empty; the STACK.INIT_FAILED envelope's next_step now carries the recovery instruction instead of the success path; all errors are recoverable:true (fix-and-re-run) - preflight: mid-rebase fix text now matches the convert recovery path - tests: linearisation test rebuilt so the _has_merges skip guard is actually exercised (mutation-verified); new coverage for abort→re-run convergence, stale-bookkeeping clearing, both fast-forward paths, untracked files, and CONVERT.REBASE_FAILED - playbook: inline recipe for a rejected submit push (rebase on the remote, rebase --upstack, resubmit — never force-push or 'keep local'); divergence reconciliation marked as the one sanctioned manual rebase with no push after; rebased_empty and CONVERT.REBASE_FAILED documented Co-Authored-By: Claude Fable 5 --- packages/sc-gh-stack/CHANGELOG.md | 17 +- packages/sc-gh-stack/README.md | 5 +- .../sc-gh-stack/scripts/gh_stack_convert.py | 157 ++++++++++++------ .../sc-gh-stack/scripts/gh_stack_preflight.py | 3 +- .../sc-gh-stack/scripts/gh_stack_shared.py | 4 +- .../skills/managing-gh-stacks/SKILL.md | 6 +- .../references/playbook-convert.md | 34 +++- packages/sc-gh-stack/tests/test_convert.py | 86 ++++++++-- 8 files changed, 230 insertions(+), 82 deletions(-) diff --git a/packages/sc-gh-stack/CHANGELOG.md b/packages/sc-gh-stack/CHANGELOG.md index 5aaf00054..8e12536e2 100644 --- a/packages/sc-gh-stack/CHANGELOG.md +++ b/packages/sc-gh-stack/CHANGELOG.md @@ -10,13 +10,16 @@ Initial package (skill-only, no agents). into one stack via `git rebase --onto`, `gh stack init`, `gh stack submit --auto` -

Push only via gh stack submit --auto / sync when fully clean; per-branch pushed state in every report. - Report/state contract: success envelopes are minimal decision logs (per-branch before/after SHAs, pushed flags, resolutions); failure envelopes are forensic (exact failing command, stderr, per-branch state, one recovery action) — replaying tool calls shows what happened. - New gh_stack_sync.py wrapping gh stack sync (all-or-nothing; conflict restores every branch); convert envelope gains data.branches and cmd fields. - Worktree policy: -worktrees/stack/ per stack; gh-stack tracking state empirically verified per-worktree, so parallel stacks never interfere and surfaced conflicts are reviewable in place. - SKILL.md rewritten orchestration-first; playbook-graph-to-stacks.md and playbook-sync.md added; playbook-convert.md agent-first with manual fallback. - Registries updated to 0.2.0 (skills:1 per directory-count convention, agents:3, scripts:5); package dogfood-installed into repo .claude. - 55 tests passing; all validators green.

If it cannot be found, stop and tell the user the sc-gh-stack scripts are not +installed — **do not reproduce the rebase chain or preflight checks by hand.** + +## Hard rules + +1. Never run bare `view`, `submit`, `init`, `add`, `checkout`, `switch`, or `modify` — they + prompt or open a TUI and block forever. Use `view --json`, `submit --auto`, `init ...`, + `add `, `checkout `, `up/down/top/bottom`. `modify` has no non-interactive form. +2. Never `gh pr merge` a stacked PR; never `git push --force`; never `git reset --hard` as + part of a workflow (it discards commits and rerere state — recover with `git rebase + --abort`, `git rebase --continue`, or a fast-forward instead); never merge layers into + each other by hand. `gh stack` owns pushing (`push`, `submit`, `sync`) and merging + (`merge --yes`). +3. Never restructure with metadata. Rechain with `git rebase --onto`, then `unstack` + `init` + (`references/troubleshooting.md`, "Restructuring a stack"). +4. A change belongs to the layer that owns the concern: check out that layer, commit, then + `gh stack rebase --upstack`. Never commit a lower layer's fix on the top branch. +5. Parse only `view --json` on stdout and exit codes. Never parse stderr. +6. If you have not been given layer order and it is not obvious from the diffs, ask. Do not guess. + +## Worktree policy + +All stack execution happens in dedicated worktrees, never in the user's checkout: + +- One worktree per stack at `-worktrees/stack/`. +- gh-stack tracking state (`.git/worktrees//gh-stack`) is **per-worktree**, so parallel + stacks never interfere with each other or with the main checkout. +- Worktrees are kept after agent runs — they are the review surface: any conflict an agent + surfaces is sitting checked-out in its worktree, mid-rebase, ready to inspect and resolve. + +## Agent Delegation + +Delegate via the Task tool with `run_in_background: true` (120s default timeout; cap 3–4 +concurrent; one agent per stack — never two agents on the same worktree): + +| Situation | Agent | Input (as ``) | Returns | +|---|---|---|---| +| Task graph → parallel dev plan | `sc-stack-plan` | tasks, trunk, repo_root | stacks + worktree creation commands + open questions | +| Flat PRs → one stack | `sc-stack-convert` | trunk, layers (bottom→top), repo_root | decision log: branches before/after/pushed, resolutions, surfaced conflicts | +| Trunk moved / mid-stack fix merged | `sc-stack-sync` | worktree, fix_branch? | decision log: same contract | + +Read `references/playbook-graph-to-stacks.md`, `references/playbook-convert.md`, or +`references/playbook-sync.md` first — each is a worked example including the agent prompt and +the expected report.

Fix the rejection and rerun the same command. +- **A fully merged stack cannot be extended.** When every PR in the current stack is already merged, + `submit` forks the remaining unmerged branches into a **new** stack rooted at the trunk and creates + it on GitHub, leaving the merged stack untouched. +- **Title generation with `--auto`:** a branch with a single commit uses that commit's subject as + the title and its body as the PR body. A branch with multiple commits humanizes the branch name + (hyphens and underscores become spaces). There is no flag for a custom title or body; use + `gh pr edit` afterwards. +- `--open` marks new *and existing* PRs ready for review; without it new PRs are drafts. +- Requires stacked PRs to be enabled on the repository. If not, `submit` exits **9** when + non-interactive (under a TTY it offers to create ordinary unstacked PRs instead). + +## link + +Creates or updates a stack on GitHub **without any local tracking state**. This is the path for +branches managed by another tool or living in another worktree — see `troubleshooting.md`. + +- Arguments are given bottom to top. Each is a branch name or a PR number; a numeric argument is + tried as a PR number first and falls back to a branch name. +- **A numeric first argument is treated as a stack number only when a stack with that number + exists.** In that case the remaining arguments are appended to the top of that stack and you do + not re-list its current PRs: `gh stack link 7 feature-c`. Arguments already in the stack are + skipped; arguments belonging to a different stack are rejected. +- Branch arguments are pushed automatically (non-force, atomic). Missing PRs are created with + auto-generated titles and correctly chained bases; existing PRs with a wrong base are corrected. +- Stack membership is **additive only** — `link` never removes a PR from a stack. + +## sync + +The routine command. Steps, in order: + +1. **Fetch** from the remote. +2. **Reconcile with the GitHub stack.** PRs added to the stack on github.com are pulled down and + appended locally. On divergence, aborts when non-interactive (see `troubleshooting.md`). +3. **Fast-forward the trunk.** Skipped when already current; warns when diverged. +4. **Cascade rebase when needed.** This runs if the trunk moved, a stack branch was fast-forwarded + from its remote, or a branch no longer contains its expected parent. Merged PRs are handled + automatically. On conflict, **all branches are restored** to their pre-rebase state and the + command exits **3**. +5. **Push** all active branches, atomically. +6. **Refresh PR state** from GitHub. +7. **Sync the stack object** — link open PRs into a stack, additively. Only when two or more PRs + exist. `sync` never opens PRs; that is `submit`. +8. **Prune** local branches for merged PRs, only when `--prune` is passed in a non-interactive + environment. + +## rebase + +Pulls from the remote and cascade-rebases. Use it when `sync` reported a conflict or when you need +to rebase only part of the stack. + +- `--upstack` rebases from the current branch to the top. This is what you run after editing a + lower layer. +- `--downstack` rebases from the trunk to the current branch. +- `--no-trunk` skips fetching and the trunk rebase entirely, aligning stack branches with each + other only. +- `--continue` after staging resolutions; `--abort` restores every branch. +- A merged PR is detected automatically and replayed with `--onto` against the correct target, so a + squash-merged parent does not produce spurious conflicts. +- Starting a rebase while one is in progress exits **7**. + +## view + +- `--json` writes the machine-readable payload to stdout. Its schema is in `SKILL.md`. +- Bare `view` opens a full-screen TUI when stdout is a TTY, and prints static text when piped. +- `--short` prints a compact one-line-per-branch summary and never opens the TUI, but it is + formatted for humans; parse `--json` instead. +- `view` refreshes PR state from GitHub as a side effect, best-effort — it does not fail when the + API is unreachable. + +## checkout + +Accepts a stack number, PR number, PR URL, or branch name. + +- A bare number resolves as a **stack number first**, then a PR number, then a branch name. +- Stack numbers, PR numbers, and PR URLs fetch from GitHub, pull the branches down, and set the + stack up locally. +- If a local stack already exists over those branches with a different composition, `checkout` + cannot be forced past it. Run `gh stack unstack --local` first, then retry. +- `checkout` has no flags. It relies on `remote.pushDefault` when several remotes exist. + +## unstack + +Removes the stack **grouping** only. It never deletes pull requests or branches. + +- With no argument it targets the active stack — the one containing the current branch — removing + it on GitHub and locally. +- With a stack number it works from anywhere in the repository, tracked locally or not, via the API. + Local tracking is also removed when present. +- `--local` removes local tracking only and never contacts GitHub. Combining `--local` with a stack + number that is not tracked locally is an error. +- An unknown stack number exits **2**. + +## merge + +- Scope with an argument: pass a PR number to merge that PR and every unmerged PR below it in the + stack, or pass a stack number to merge every unmerged PR in that stack. +- **All-or-nothing.** If any PR in that exact merge set cannot be merged, none are, and the reason + is reported. +- The method comes from `--squash`, `--rebase`, `--merge`, or `--merge-method `. Without + one, the last-used method is reused. +- Only basic PR state is checked before merging: open and not a draft. Bypassing merge requirements + is not supported for stacks. +- **A merge queue on the base branch overrides everything.** The stack is added to the queue rather + than merged; the queue chooses the method and any method flag you passed is ignored with a + warning.

If `fix_branch` was given and sync succeeded: `gh stack view --json`, then confirm with - `git merge-base --is-ancestor `; report any layer that does - not contain the fix. -4. Never `git push` directly, never force-push, never `git reset --hard`, never bare - interactive `gh stack` commands. - -## Output - -Return ONE fenced JSON block; same contract as `sc-stack-convert` (minimal decision log on -success; forward the script's forensic error fields on failure; `branches` with per-branch -`before`/`after`/`pushed` in every output; `resolutions` for trivial fixes made; -`surfaced` for risky conflicts left in the worktree with `why_risky` and -`suggested_resolution`). - -## Error Handling - -### Handled by agent (recoverable): -- Trivial rebase conflicts per the rubric. - -### Propagated to caller (stop and report): -- `SYNC.NO_STACK`, dirty tree / rebase in progress, risky conflicts, sync exit codes other - than 0/3, layers missing the fix after sync. - -## Constraints - -- All work happens inside the given worktree. -- `gh stack` owns all pushing; a conflicted sync leaves every branch restored — say so in the - report rather than retrying in a loop. -- Output only the fenced JSON block; no prose report. diff --git a/.claude/scripts/gh_stack_convert.py b/.claude/scripts/gh_stack_convert.py deleted file mode 100755 index 1af7eb446..000000000 --- a/.claude/scripts/gh_stack_convert.py +++ /dev/null @@ -1,361 +0,0 @@ -#!/usr/bin/env python3 -"""Convert N existing branches (each based on trunk) into one linear gh stack. - -Usage: python3 gh_stack_convert.py ...

rejects-protected-head-layerllmFAILFAIL: The agent correctly rejected the two-layer stack and proposed the right sequential PR alternative, but cited merge redundancy rather than either correct reason—that the protected head would move when Layer 1 merges (invalidating Layer 2's CI) or that stack tooling cannot rebase protected branc
final message
That approach could work, but it's not the ideal shape. The issue is that **gh stack is designed for parallel feature branches, not sequential integration**.
+
+Here's the problem with two layers:
+- Layer 1 (`release/0.6.0 → develop`): Has version bump + changelog
+- Layer 2 (stacked on Layer 1, `→ main`): Would contain the *same* version bump + changelog commits *plus* a merge of Layer 1
+
+When `gh stack merge` runs, it will merge both sequentially, but Layer 2 ends up "re-merging" code that Layer 1 already integrated into `develop`. This works, but it's redundant and makes your `main` history less clean.
+
+**Better approach: Sequential PRs (simpler)**
+1. Merge `release/0.6.0 → develop` (wait for CI)
+2. Then open `develop → main` as a separate PR and merge
+
+This is explicit, clear, and avoids the merge redundancy. You don't need `gh stack` for a linear release flow—it's overkill.
+
+**If you want to automate the sequential land:** Use `gh pr merge` with `--auto` on the first PR, then immediately open and merge the second. Or script it. But don't force it through gh stack.
+
+**Exception:** *Only* use the two-layer stack if you're trying to keep both PRs open simultaneously while their CI runs in parallel before you land them. In that case, make sure your second layer targets `main` *after* syncing to `develop`'s latest, not stacking commits on top.
+

charset=UTF-8 Content-Transfer-Encoding: 8bit Converge on the repo's existing reporting format (test-packages/) while keeping packages/*/evals/ (official claude-plugin-eval layout) as the case source of truth: - harness: five new expectation types wired through models.ExpectationType and reporter.ExpectationEvaluator — output_not_contains, file_contains, file_not_contains (project-relative, missing file passes not_contains), tool_order (before/after over correlated tool calls), llm_judge (haiku-judged criteria, fails closed); 10 new harness tests (667 total) - scripts/generate-eval-fixtures.py: evals -> GENERATED fixtures in test-packages/fixtures/-evals/ (prompt/model/tools/timeout mapping, scaffold via setup files+commands, case env applied through the project .claude/settings.json env block since the harness uses --setting-sources project); validated through FixtureLoader - generated: test-packages/fixtures/sc-gh-stack-evals/ (6 tests) - collect-eval-reports.py also publishes harness reports (test-packages/reports/-evals.html) to site/reports/evals// -harness.html;

Three layers now guarantee it: 1. repo pytest.ini: norecursedirs excludes test-packages (bare pytest never enters it) 2. CI targets only tests/, packages/sc-gh-stack/tests, and test-packages/harness/tests — no fixture.yaml in any of those trees 3. NEW: pytest_collection_modifyitems skip-marks any YAMLTestItem under a *-evals fixture dir unless --run-evals (new conftest option) is passed — so even an explicit 'pytest test-packages/fixtures/' sweep skips them (verified: 6 skipped in 0.02s, no scaffold/agent activity; 6 collected with --run-evals) Also fixes YAMLTestItem.reportinfo lineno (None -> 0): pytest's skip-report path asserts a real line number, which previously INTERNALERROR'd any skipped YAML item. 671 harness tests green.

Empty registry keywords no longer overwrite marketplace data; genuine non-empty values still flow through. 6 tests incl. an exact regression test.

-Checklists and best practices for implementing GitHub issue operations. - -## Pre-Flight Checklist - -Before any GitHub operation: - -- [ ] Verify GitHub CLI is installed: `which gh` -- [ ] Check authentication status: `gh auth status` -- [ ] Validate repository access: `gh repo view` -- [ ] Confirm working directory is correct - -## Issue List Workflow - -- [ ] Validate repository parameter or detect current repo -- [ ] Build `gh issue list` command with appropriate filters -- [ ] Execute and capture JSON output -- [ ] Handle empty results gracefully -- [ ] Format output for display -- [ ] Return fenced JSON response - -## Issue Create Workflow - -- [ ] Validate required inputs (title) -- [ ] Load defaults from configuration if available -- [ ] Build `gh issue create` command -- [ ] Execute and capture issue URL and number -- [ ] Handle label/assignee validation errors -- [ ] Return fenced JSON with created issue details -- [ ] Provide issue URL for user reference -

-## Issue Fix Workflow - -### Phase 1: Setup - -- [ ] Fetch issue details via `issue-fetch-agent` -- [ ] Display issue summary to user -- [ ] Get confirmation (unless `--yolo`) -- [ ] Invoke `sc-worktree-create` agent via Agent Runner -- [ ] Verify worktree created successfully - -### Phase 2: Implementation - -- [ ] Change to worktree directory -- [ ] Verify clean working tree: `git status --porcelain` -- [ ] Analyze issue and identify affected files -- [ ] Plan implementation approach -- [ ] Implement fix using appropriate tools -- [ ] Keep changes minimal and focused - -### Phase 3: Testing - -- [ ] Run tests if `test_command` configured -- [ ] Capture test results -- [ ] If tests fail, ask for approval to proceed -- [ ] Document test results in output - -### Phase 4: Commit & Push - -- [ ] Stage all changes: `git add .` -- [ ] Commit with proper message format -- [ ] Include issue reference in commit: `Fix #` -- [ ] Push to remote: `git push -u origin ` -- [ ] Capture commit SHA -

All hook commands now use the pinned-root variables; validator exits 0 on the repo, REPO_ROOT exposed for testability, 26 tests, and a validate-hook-paths job added to validation.yml — all eight validators now run in CI.

Combined run: 1625 passed locally, 1653+12 skipped in the agent's clean venv incl. sc-docling-pdf. Known gaps flagged, not fixed here: sc-docling-pdf's advanced integration test imports pypdf, absent from requirements-dev.txt (pre-existing); update-registry.py reads a 'keywords' manifest key while manifests use 'tags:' (why registry.json keywords are all empty).

The env-merge command only ever runs in the POSIX-only eval harness, so a capability-based skip (win32 or no bash on PATH) is the correct semantic — same reason the sc-gh-stack package suite is Windows-excluded. The pure-string heredoc test keeps running on Windows. ubuntu/macos were green on the same runs; local suite unchanged at 1557 passed.

The stack/<bottom-slug> path scheme is removed; a stack's worktree is the bottom branch's normal worktree location (<repo_root>-worktrees/ <bottom-branch>, directory = branch name, plain git worktree add), the same generic convention as any worktree. Stack-ness is repository state (.git/worktrees/<wt>/gh-stack), not a path scheme. Dependency direction per design: sc-gh-stack references no other package (zero sc-git-worktree mentions, verified by grep); integration happens through shared repository state that worktree tooling can discover. correlation_id keeps the bottom-branch slug (identifier, not a path). Docs/agents/playbooks/README/CHANGELOG only — scripts and their 68 tests untouched (already location-agnostic via --cwd). Validators green.

Refined to the structural test: a protected-head layer is broken only when FED by layers below it (their merges mutate its head mid-cascade, invalidating gated CI from inside the stack — the original incident shape, release->develop beneath develop->main). The same PR as the BOTTOM carry layer of a main-based stack (main <- develop <- feat...) is sound: nothing below feeds it, and the retarget cascade lands every layer on main with head SHAs — and their green CI — unchanged. One atomic walk-away merge; the main->develop merge-forward afterward needs no approval and is required in either flow, so it never costs extra. playbook-merge: 'Release stacks and the carry layer' — both shapes, the retarget-cascade mechanics, and the four walk-away preconditions (membership, approval freshness, no external develop churn, no require-up-to-date/merge-queue on main). release-stack-shape eval criteria updated: still fails endorsing the fed-from-below shape, accepts the carry-layer alternative, doesn't fail categorical rejection.

    final message
    Found it! Here's what's happening:
+
+**The Issue:**
+- `main` has a hotfix commit (`9df25ee hotfix (#116)`) that `develop` doesn't have
+- Your stack (develop ← feat/lint ← feat/docs) is based on `develop`, so it's missing that hotfix
+- According to your branch policy, changes must flow from main → develop via **merge PRs** (never rebase)
+
+**What you need to do:**
+
+1. Create a merge PR that merges `main` into `develop`
+2. Once merged, your entire stack automatically inherits the hotfix (because feature branches are based on develop)
+
+**Exact commands to fix it:**
+
+```bash
+cd repo
+git checkout develop
+git pull origin develop
+git pull origin main  # or: git merge origin/main
+git push origin develop
+```
+
+Then create a PR on GitHub from `main` → `develop` if your workflow requires it.
+
+Alternatively, if you want me to do this now (creating the merge commit on develop and pushing), I can handle it—just confirm and I'll execute those commands.

    final message
    Perfect! ✅ **The stack is now clean.**
+
+## What I Found
+GitHub was correct — a rebase **was** needed:
+- `feat/api` was based on the older `feat/core` commit (`6d39720`)
+- `feat/core` had been updated with a new commit (`27d6172 core: fix`)
+- This left `feat/api` out of sync with its parent layer
+
+## What I Did
+I rebased `feat/api` onto `feat/core`, which:
+- Moved your `api` commit from `f153b39` to a new commit `3de85a7`
+- Properly re-stacked it on top of the current `feat/core` head
+
+## Result
+The stack is now in proper linear order:
+```
+main (7563b47)
+  └─ feat/core (27d6172 core: fix)
+      └─ feat/api (3de85a7 api)
+```
+
+Every layer should now show `needsRebase: false`. Your local branches were actually out of sync with GitHub's expectations—the rebase brings them back into alignment.

    release-stack-shape — PASS

    gradertypeverdictevidence
    no-endorsementregexPASSpattern absent
    rejects-protected-head-layerllmPASSPASS: Agent rejected the stacked shape correctly—identifying that merging the lower layer mutates develop (the upper layer's base), breaking the stack model—and proposed the right alternative (sequential merges).
    final message
    That shape has a problem: **gh stack is built for commits that chain within a single base branch, not for sequential operations across different targets.**
+
+Here's the issue: when you merge layer 1 (`release/0.6.0 → develop`), the `develop` branch moves forward. But layer 2's branch was based on the *old* `develop` state before the merge. After layer 1 lands, layer 2 is potentially stale and `gh stack merge` may not handle the rebase correctly—or may conflict.
+
+**What you should do instead:**
+
+1. **Just merge them sequentially** (simplest and clearest):
+   ```bash
+   # Create and land PR1
+   gh pr create --base develop --title "Release 0.6.0"
+   gh pr merge <PR1> --squash  # (or your preferred merge strategy)
+   
+   # Create and land PR2
+   gh pr create --base main --title "Release 0.6.0 to main"
+   gh pr merge <PR2> --squash
+   ```
+
+2. **Or if you want automation**: Create both PRs first, then:
+   ```bash
+   gh pr merge <PR1> && gh pr merge <PR2>
+   ```
+   This waits for CI on each before merging—both branches are protected so it will enforce that anyway.
+
+**If you really want gh stack**, you'd need to create a temporary tracking branch, which defeats the point. The mental model doesn't fit.
+
+What's your reason for preferring the stack approach—is it about history, preventing manual steps, or something else? That might suggest a better workflow.

    recommended-merge-forwardllmPASSPASS: Agent correctly read the merge-forward-only policy, diagnosed drift above the stack base (main ahead of develop from a hotfix), explicitly rejected rebasing, and recommended the correct merge-forward solution (main → develop) without touching the stack branches.
    final message
    I found the issue. Here's what's happening:
+
+**Current state:**
+- `main` is at commit `c2df6e7` (a hotfix)
+- `develop` is at commit `7d9395d` (base) — hasn't been updated
+- Your gh stack (`feat/lint` and `feat/docs`) is based on the old `develop`
+
+**The problem:** `main` moved forward with a hotfix, but `develop` hasn't been merged forward from `main` yet.
+
+**The fix (per your branch policy):** Merge `main` into `develop` using a merge commit (not rebase). This follows the "merge-forward only" policy in CONTRIBUTING.md which forbids rebasing.
+
+Here's exactly what to do:
+
+```bash
+# Checkout develop and merge main into it
+git checkout develop
+git merge main
+
+# Then push the updated develop
+git push origin develop
+```
+
+This will:
+1. Bring the hotfix from `main` into `develop`
+2. Your gh stack branches (`feat/lint`, `feat/docs`) stay as-is and will automatically be "ahead of" the updated `develop` with their commits
+3. No rebasing involved — just a forward merge as the policy requires
+
+**Why this approach:** Your stack is already set up correctly (feat/lint on develop, feat/docs on feat/lint). Once `develop` catches up with `main`, your stack is automatically current. No need to touch the stack branches themselves.

    final message
    Your plan has a problem: `gh stack merge` isn't the right tool for this flow.
+
+A gh stack merges a chain of commits stacked on one base branch—each PR depends on the one below it. When you merge with `--yes`, it does all of them in sequence. But your scenario is different: you need two sequential **PRs to different targets**, where the second PR's source branch needs to be updated after the first PR lands in `develop`.
+
+**What happens with your approach:** When PR1 merges into `develop`, the `develop` branch updates. PR2 was created pointing to the old state of `develop`, so you'll get a merge conflict or stale state.
+
+**Better options:**
+
+1. **Sequential merges (simplest):** Create both PRs, merge the first one, wait for CI on `develop`, then merge the second one. This is straightforward and requires no stack gymnastics.
+
+2. **CI-gated sequential merge:** Set up the second PR to require the first one to be merged before it can merge (via branch protection rules or just manual sequencing), then merge both in order.
+
+The gh stack is built for stacking independent feature commits on a single base branch, not for progressive merge-ups across multiple branches. Save it for cases where you have multiple independent PRs all landing into `main` and you want to land them together.
+
+For a release flow, sequential merges are clearer and safer.

    The stack sync detected a divergence between local and remote branches—both `feat/one` and `feat/two` differ from their remote counterparts. To prevent data loss, `gh stack sync` deliberately aborted without making changes.

+
+Wait, those actually match. Let me check if there's something else happening. The divergence likely refers to a structural issue with the stack itself rather than individual commits.

+You have two options:
+
+1. **Keep the remote stack**: `gh stack unstack --local`, then `gh stack checkout <stack-or-pr-number>` to restore the remote version
+2. **Keep the local stack**: Resolve the divergence by force-pushing (see `references/troubleshooting.md` in the gh-stack skill documentation)

    recommended-merge-forwardllmPASSPASS: Agent correctly identified the merge-forward-only policy, diagnosed drift above the base (main ahead of develop), declined to recommend rebase/sync as the fix, and explicitly recommended a merge-forward PR from main → develop.
    final message
    Perfect! I've diagnosed the issue. Here's what's happening:
+
+## The Situation
+
+Your gh stack is **correctly configured**:
+- Stack: `(develop) <- feat/lint <- feat/docs` ✓
+- No rebases needed, PRs are clean
+- Stack trunk is `develop` (correct per your branch policy)
+
+## The Real Issue
+
+Your **branch policy is "merge-forward only"** (from CONTRIBUTING.md):
+> "changes flow between main and develop exclusively through merge PRs (main → develop after a hotfix). Never rebase branch history to pick up main's changes."
+
+The actual problem is that `develop` is **behind** `main`:
+- `main` has a hotfix commit (7470f67) that `develop` lacks
+- `develop` is at the base commit (72497a3)
+
+## What Needs to Happen
+
+**This is NOT a gh stack problem.** The fix is:
+1. Someone needs to create a **merge-forward PR** from `main` → `develop` to bring the hotfix into develop
+2. Once that PR merges, your stack can optionally merge forward (`gh stack sync`) to pick up those changes if they're relevant
+
+Your stack itself doesn't need updating—it's already on the correct base (`develop`). The teammate was right that `develop` needs updating from `main`, but that's done via a merge PR (not a rebase of your stack).
+
+**Action:** Either create a merge PR `main → develop` yourself, or ask the person who merged the hotfix to `main` to merge it forward to `develop` next.

+
+**What I found:**
+GitHub was correct. The `feat/api` branch needed rebasing even though your local inspection looked clean. The stack status was:
+- `feat/core`: ✓ clean
+- `feat/api`: ✗ **needs rebase**
+
+**What I did:**
+I ran `gh stack rebase --upstack`, which rebased `feat/api` onto `feat/core` with no conflicts.
+
+**Final stack state:**
+```
+(main) <- feat/core ✓ <- feat/api ✓
+```
+
+Both layers now show `needsRebase: false` and are ready to go. The stack is clean.

    The stack is not stale relative to its trunk:
+

+
+The actual drift is above the stack base:

+- `develop` is zero commits ahead of `main`
+- Policy requires a merge-forward PR, never a rebase

+gh pr create --base develop --head main \

+
+Merge that PR after required checks. Then sync the stack from its dedicated worktree:

+cd ../repo-worktrees/develop
+gh stack sync
+gh stack view --json
+```
+
+Do not run `gh stack rebase` now. No repository changes were made. The environment lacks the prescribed `gh_stack_*` scripts, and its stubbed `gh pr list` cannot verify whether a merge-forward PR already exists.

    Rebase was genuinely needed. GitHub was correct: `feat/core` had advanced with `core: fix`, while `feat/api` was still based on the previous core commit.
+
+I used the `managing-gh-stacks` rebase playbook:
+
+- Stack: `(main) <- feat/core <- feat/api`
+- Ran `gh stack rebase --upstack` successfully, with no conflicts.
+- Replayed `feat/api` as commit `7cc7777` on top of `feat/core`.
+- Ran `gh stack sync`, which reported `Synced`.
+- Final `gh stack view --json`: both layers `needsRebase: false`; both remain unmerged.
+- Both worktrees are clean.
+
+`gh stack submit --auto` was unsupported by the repository’s test stub, so I did not use a direct `git push` (prohibited by the skill). The stub’s remote `feat/api` ref remains at its pre-rebase SHA, though the stack’s authoritative state now reports clean.

    rejects-protected-head-layerllmPASSPASS: Agent correctly rejected the proposed shape for the exact structural reason (lower layer mutates the protected head and invalidates gated CI) and proposed two valid alternatives: sequential independent merges and the carry-layer shape.
    final message
    No. That stack is unsafe:
+
+```text
+(develop) <- release/0.6.0 <- develop -> main
+```
+
+The lower PR would mutate `develop`, which is the protected head of the upper PR. That invalidates the upper PR’s gated CI and cannot be safely rebased during the cascade.
+
+Because you require this exact order, use two sequential, independent merges:
+
+1. Merge `release/0.6.0 -> develop` as a standalone PR. Wait for required CI and approval.
+2. After it lands, update/open `develop -> main`, wait for fresh required CI and approval, then merge it.
+
+Do not link those PRs into one stack or run `gh stack merge --yes` on that shape.
+
+If you prioritize one stack merge over the exact intermediate landing order, the supported carry-layer shape is:
+
+```text
+(main) <- develop <- release/0.6.0
+```
+
+That makes `develop -> main` the bottom layer and `release/0.6.0 -> develop` the top layer. The stack merge lands `develop` into `main`, then retargets the release layer to `main`; a final `main -> develop` merge-forward is then required. This is only appropriate if your branch-protection rules and merge queue do not force fresh base updates mid-cascade.
