Lane: openreposhape-3 (openRepoShape-3)
Claim: #204 (comment)

Seven commits, to land as one squash. The final message is drafted by the lane:

• 6ed4e70: the fix;
• 8705b27: fix round 1, SonarCloud S8705;
• 60038cc: fix round 2, the independent review;
• be70651: merge of main 39ac59c, which carries update-shape.py: apply keeps each of the manifest's shape: pin lines at the indentation it already has and reads the rewrite back, so a project.yaml indented four spaces takes the update instead of being rolled back under the validators' lockstep remedy (#208) #224 and update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233; the update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233 conflict is resolved as this body said it would be;
• c96396b: fix round 3, tests for a failure before the commit under --push --pr;
• 87ba8c5: merge of main 2727b08, which carries update-shape.py apply --branch prints the root's own tracking branch as the gh pr create --base and its assembly repository as the --repo, the two values --pr passes, so a project scaffolded with --tracking-branch trunk is no longer told to open its pull request against main, and the --push line no longer prints a literal <org>/<Project> that a shell reads as a redirection (#209) #218, shape_materialize.run() and 26 other git and gh calls read what the child wrote as UTF-8 whatever the locale, so an adopt-project.py execute whose leg push is rejected with a message naming a non-ASCII path ends REFUSED pushing the spec leg and the ruleset hint under LC_ALL=C PYTHONUTF8=0, not a UnicodeDecodeError traceback (#217) #230 and adopt-project.py and five other tools escape a name their stdout cannot encode, so plan on 日本.md under a cp1252 stdout (strict, or Windows' default surrogateescape) no longer exits 1 after writing the plan (#214) #246; update-shape.py apply --branch prints the root's own tracking branch as the gh pr create --base and its assembly repository as the --repo, the two values --pr passes, so a project scaffolded with --tracking-branch trunk is no longer told to open its pull request against main, and the --push line no longer prints a literal <org>/<Project> that a shell reads as a redirection (#209) #218's no-repository test now calls pull_request_target;
• c874e4f: fix round 4, update-shape.py apply --branch prints the root's own tracking branch as the gh pr create --base and its assembly repository as the --repo, the two values --pr passes, so a project scaffolded with --tracking-branch trunk is no longer told to open its pull request against main, and the --push line no longer prints a literal <org>/<Project> that a shell reads as a redirection (#209) #218's --repo on the gh pr create a failed --push prints.

What

_land commits, pushes and opens the pull request. A failed push or gh pr create used to reach cmd_apply's one except CommandFailed arm. That arm called every failure "committing the re-synced shape", printed no NEXT line and did not flush stdout. A missing gh escaped as a traceback. The re-run then said "nothing to do" and exited 0. The commit is now where rolling back stops:

• The failing step is named. push_branch and open_pull_request hand their failure to landing_failed, which prints REFUSED pushing <branch> or REFUSED opening the pull request for <branch>. It says the commit stands and nothing was rolled back, and ends on a NEXT line. The exit is 2.

• A program that cannot be started is that same failure (round 2). _landing_run turns OSError, such as gh not installed or not on PATH, into exit 127 with the message "gh could not be started (…): is it installed and on PATH?".

• The NEXT line is the command that failed. It is the gh pr create that --pr runs, title and body included, shell-quoted so it pastes back as the same argv. pull_request_line builds it before the commit.

  • When origin does not have HEAD on the branch, the line pushes first: git -C <root> push -u -- origin <branch> && gh pr create ….
  • "Origin has it" is read from for-each-ref --points-at HEAD refs/remotes/origin/, so the branch name is never a git argument there.
  • Under --push without --pr, it ends on gh pr create --repo <repository> --base <tracking> --head <branch>, the bare form update-shape.py apply --branch prints the root's own tracking branch as the gh pr create --base and its assembly repository as the --repo, the two values --pr passes, so a project scaffolded with --tracking-branch trunk is no longer told to open its pull request against main, and the --push line no longer prints a literal <org>/<Project> that a shell reads as a redirection (#209) #218's --branch NEXT line prints (round 4). A manifest that names no repository leaves --repo off rather than printing a placeholder inside a line quoted as an argv.

• stdout is flushed before the refusal, so a combined log reads commit, push, REFUSED, NEXT.

• LandingIncomplete carries the exit 2 to main. It is neither of the two classes that cmd_apply's arm hands to update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's _rolled_back. So a failure after the commit never undoes the commit that ledger.land() closed the ledger on, and the step is never renamed "committing".

• A failure before the commit is still update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's rollback, with --push and --pr passed too (after the merge; tests in round 3). A branch, a stage or a commit that fails puts back the copies, the pin, the README line, the index and the branch, and names the step. Nothing of the landing happens: no push, no gh call, no NEXT line, no re-run promised.

• A re-run with --pr finishes the landing. This applies when there is nothing to write, the checkout is on --branch, that branch is not the tracking branch, and its contracts/shape-pin.yaml differs from origin/<tracking>'s. _finish_landing asks gh pr list --state all first:

  • if a pull request is open, it is reported and no second one is opened;
  • if it was merged or closed, that is reported and nothing is pushed;
  • if there is none, --push pushes again and the same gh pr create runs. There is no second commit.

• The refusal promises that re-run only under --pr. When origin does not have the branch, it names apply --push --pr.

• --branch is checked once, in main, before anything is read, written or run (round 1). checked_branch refuses with REFUSED update-branch-invalid and a remediation line unless:

  • BRANCH_RE fullmatches the value: checked_value's alphabet less ~, with a letter or digit first, so there is no leading -, +, / or .;
  • and git check-ref-format --branch then echoes it unchanged.

  This happens whether or not there is anything to write.

• git push -q -u -- origin <branch>: -- ends git's options before the positionals.

• --pr help: a later run on the branch opens the pull request if it is still missing. docs/cli.md is regenerated.

Why

The issue's repro, re-measured on this machine against main 2727b08, which carries #218. Atlas is scaffolded from a clone of main 39ac59c into local bare remotes, with one upstream commit B (25ff23b96682); the tree under test is main 2727b08 against this branch at c874e4f. gh is a PATH shim that logs its argv and exits 97 on pr create while a marker file exists. Every run uses the same path and fixed git dates, so outputs compare byte for byte.

run	main 2727b08	this branch (c874e4f)
r1 --branch shape/update-y --push --pr, gh pr create fails	exit 2 REFUSED committing the re-synced shape, no NEXT line	exit 2 REFUSED opening the pull request for shape/update-y; …origin has it: that commit stands and nothing was rolled back; NEXT = the gh pr create the shim logged

check; --branch and its re-run; --branch --push and its re-run; --branch --push --pr with gh succeeding; --branch=shape/update-y --push --pr		byte-identical to main in stdout, stderr, exit code and the gh argv log (cmp)
r10 --branch --push --pr, a pre-commit hook refuses; r10b the same command once the hook is gone		byte-identical to main. r10: exit 2 REFUSED committing the re-synced shape on shape/update-y, then #233's ROLLED BACK block; origin has no branch, only main is left, the tree is clean, gh is never called. r10b: exit 0, committed, pushed, one gh pr create, 1 commit

Tests

tests/test_update_shape_landing.py has 33 tests.

Round 4 asserts --repo testorg/Atlas in the landing failed_push[push] line. It also checks both pull_request_line forms in #218's repository test (project, and both family spellings), and the bare form without --repo in #218's no-repository test. Run against the merge commit 87ba8c5, which does not have the change, these give 4 failed, 8 passed: the three repository cases and failed_push[push] fail, and the no-repository guard passes before and after. Its first 15 gave 10 failed, 5 passed on main a5b09c3. The 5 that pass there pin behaviour that must not change.

Round 3 adds two tests:

• test_a_failure_before_the_commit_under_push_and_pr_is_rolled_back runs on every platform, because gh is never reached.
• test_the_same_command_after_a_rolled_back_commit_lands_and_opens uses the gh stub.

In the merge, #233's branch-invalid case in tests/test_update_shape_add_ignored.py becomes test_a_branch_git_cannot_name_is_refused_before_any_write. That test asserts update-branch-invalid, empty stdout, and a tree untouched with the operator's staged work in it.

Mutations, each run against the whole file:

• 6ed4e70: 16 of 16 killed;
• round 1: 4 of 4 killed (the entry check, git's authority, --, the pushed-ref read);
• round 2: removing the OSError arm fails both missing-gh tests;
• round 3, against landing + test_update_shape_add_ignored.py:
  • M1: a failure after the commit is rolled back (the ledger is reopened and undone on LandingIncomplete). Result: 13 failed, 12 landing tests plus update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's test_a_failure_after_the_commit_lands_rolls_nothing_back.
  • M2: a commit failure is reported as a landing failure whenever --push or --pr is passed. Result: 2 failed, 10 passed. Only the two new tests kill it; every one of update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's own cases survives it. Under M2 the re-run even says "nothing to do" over the uncommitted re-pin, which is update-shape.py apply --add stages the new file with a plain git add, so a path the operator's excludes ignore fails after the copies, the re-pin and the branch are written, nothing is rolled back, and check then exits 0 over a re-pin nobody committed #202's original bug.

Targeted set on c874e4f71058bd6bba94ae100c92603ef8d4a6d1:
tests/test_update_shape.py, tests/test_update_shape_add.py, tests/test_update_shape_add_ignored.py, tests/test_update_shape_landing.py, tests/test_update_shape_pr_base.py, tests/test_shape_doctor.py, tests/test_repo_hygiene.py, tests/test_cli_reference.py → 424 passed in 839.27s (0:13:59). At c96396b, before #218, it was 397 passed.

scripts/render-cli-reference.py --check: [ok]. Merging main did not change any --help text. pyflakes is clean on update-shape.py and both test files.

Base tested: 2727b08. Main has since moved to 4b2add8 (#257, scripts/repo_shape.py flow mappings and its own test); git merge-tree --write-tree 4b2add8 c874e4f is clean.

On Windows:

• 9 landing items skip as WINDOWS_SKIP (8 functions, one parametrized twice), because they drive the gh shell-script stub and CreateProcess reads no shebang.
• test_a_gh_missing_from_path_is_the_step_that_failed_on_both_runs skips wherever gh lives beside git or Python, which is the case on the Linux runners (all three in /usr/bin). Elsewhere it runs.
• Two in-process tests cover the issue's two runs and the two missing-gh runs on every platform.
• The 13 --branch tests and the round-3 rollback test also run on every platform. The rollback test's hook is a shebang script, which Git for Windows runs through its own sh, as update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's tests rely on.

#233, as merged in be70651. These are the steps this body stated before #233 landed. I re-derived them against the landed 150c41d, which is much larger than the c022b64 they were first trialled on:

1. EXIT CODES apply line: one sentence, "2 a REFUSAL, including a validator that went red or a branch, stage or commit that failed (rolled back); or a push or pull request failing after the commit, which is KEPT, and the NEXT line printed then finishes the job (update-shape.py apply --branch --push --pr: when gh pr create fails after the commit and the push succeeded, it exits 2 with "REFUSED committing the re-synced shape" and no NEXT line, and a re-run on that branch says "nothing to do" and exits 0, so the tool never opens the pull request #204)".
2. _land docstring: both paragraphs, update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's ledger sentence first.
3. The third hunk: update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's _rolled_back, then this branch's LandingIncomplete … pull_request_target block. Only update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's old def open_pull_request(root, branch, target, upstream, kind) header is dropped.
4. The stale sentence in _rolled_back: it now says that a push or pull request failing after the commit never reaches that arm. LandingIncomplete is neither of the arm's classes.
5. tests/test_update_shape_add_ignored.py: the branch-invalid entry leaves FAILURES and becomes its own test (see Tests). checked_branch refuses shape/update..ignored in main before anything is written. update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's branch-df case still covers a branch git cannot create after the writes.

Lane 4 resolved the same merge independently (its landing note on this PR, 22:06Z). Its tree has the same code, and the same _land docstring, as be70651. The two differ in three places only: the line wrap in step 1, the wording in step 4, and that lane 4 deletes the branch-invalid case where be70651 keeps it as a test.

#218, as composed in 87ba8c5 and c874e4f. #218's pull_request_repository merged into pull_request_target, where this branch moved the manifest reading open_pull_request used to do. So --pr, the failure NEXT line and the re-run's gh pr list all read one repository and one base. The two changes the second lander owed are made:

1. test_a_manifest_naming_no_repository_refuses_pr_and_leaves_the_placeholder calls update_shape.pull_request_target(tmp_path, kind) in place of the old five-argument open_pull_request (87ba8c5). update-shape.py apply --branch prints the root's own tracking branch as the gh pr create --base and its assembly repository as the --repo, the two values --pr passes, so a project scaffolded with --tracking-branch trunk is no longer told to open its pull request against main, and the --push line no longer prints a literal <org>/<Project> that a shell reads as a redirection (#209) #218's docstrings that named open_pull_request as the manifest's reader now name pull_request_target.
2. pull_request_line's bare form carries --repo (c874e4f), so every gh pr create this tool prints or runs names the repository.

Left out

• A --pr re-run over a working tree whose contracts/shape-pin.yaml or manifest differs from HEAD's (an in-place apply --at C on the branch) pushes HEAD and titles the pull request with C. It should require a clean pin and manifest, or refuse.
• The NEXT line uses POSIX quoting (shlex.join), which cmd.exe does not read.
• Most of the shell-stub re-run tests skip on Windows; more in-process tests would carry them there.
• The adopt-side form of the unflushed log is adopt-project.py: a failure AFTER both legs are pushed (the split-branch push, the mount, the split commit) prints only REFUSED <step> with no notice of what already exists and no stdout flush, so the combined log shows REFUSED before the bare … lines and the re-run meets leg-remote-exists unexplained #188.

Closes #204

Reviewer's Guide

The PR changes landing so commits remain intact when pushing or opening a pull request fails, reports the precise failed step with a pasteable recovery command, and allows a subsequent eligible --pr run to discover or create the missing pull request without recommitting; documentation and extensive regression tests cover the new flow.

File-Level Changes

Change	Details	Files
Preserve post-commit landing state and report the exact failing step with a recoverable NEXT command.	Build the pull-request command before committing so failure guidance reproduces the original arguments. Handle push and pull-request failures separately, flush prior output, keep the commit, and return exit code 2 through a dedicated exception. Generate shell-quoted NEXT commands that include a prerequisite push when the branch is not known on origin. Update apply exit-code documentation and CLI help.	update-shape.py docs/cli.md
Complete missing pull requests on eligible no-write re-runs without creating a second commit.	Detect re-runs only for --pr on the checked-out non-tracking branch whose pin proposes a change. Query all pull-request states before pushing; avoid duplicate PRs and avoid restoring merged or closed remote branches. Push when necessary and reuse the original PR creation command, including failure handling.	update-shape.py
Add comprehensive regression coverage for post-commit failures and recovery behavior.	Test failed push and PR creation messages, ordering, command quoting, retained commits, and exit codes. Test successful re-runs, existing/open and merged/closed PRs, branch guards, tracking-branch behavior, and no-PR compatibility. Use isolated bare remotes and a controllable gh stub, with an in-process test for cross-platform coverage.	tests/test_update_shape_landing.py

(lane openRepoShape-3, 2026-10-11T19:19Z) fix round 1: SonarCloud S8705 (2 findings at update-shape.py:957 and :2002) fixed in 8705b27 by checking --branch once in main (allowlist fullmatch, then git check-ref-format --branch, refused as update-branch-invalid before anything runs), reading the pushed state without the branch as a git argument, and -- before the push positionals; targeted set 350 passed on 8705b27.

This lane reviewed PR #227 at 6ed4e70 read-only, in its own detached worktrees. It authored nothing and holds no claim.

MERGEABLE WITH NITS. Whichever of #227 and #218 lands second changes one test call. #233 conflicts in 3 hunks, and keeping both sides resolves them. The branch has since moved to 8705b27, which was not reviewed.

The issue's two runs are fixed. Head prints REFUSED opening the pull request for shape/update-y, keeps the commit, and its NEXT line is the exact argv gh got. The re-run opens the pull request with no second commit. Main printed "committing the re-synced shape", then "nothing to do".

Findings (update-shape.py at 6ed4e70):

• P3-1: with no gh on PATH, the FileNotFoundError escapes open_pull_request (:2171-2176), _finish_landing (:2085-2088) and push_branch (:2013-2017).
  • Run 1 ends in a traceback, exit 1, no NEXT line, as on main.
  • The new re-run also ends in a traceback; main exited 0.
  • This contradicts the new EXIT CODES text (:83-85). Fix: catch OSError there and hand it to landing_failed.
• P3-2: the re-run never passes --branch through checked_value (the first run does, at :1510).
  • Probe: checkout on refs/heads/--receive-pack=<script>, then apply --branch=<that> --push --pr. It ran git push -q -u origin --receive-pack=<script>, and with push.default=current the script ran.
  • Low reach, but this is SonarCloud's red S8705. The subject of 8705b27 says it adds this check.
• Nit: building the gh pr create after the commit (:1884-1887) is a surviving mutant. The promise at :1878-1880 is untested.
• Nit: a re-run without --yes pushes and opens the pull request, because :1907-1909 runs before confirm at :1916.
• Nit: re-running a first command that had --add refuses update-add-already-pinned. The promise at :1991-1995 could say to drop --add.
• Nit: the NEXT line uses POSIX quoting (:2002-2005) and does not paste in cmd.exe.
• Nit: Sonar S9073 at tests/test_update_shape_landing.py:197 and :225.

Tests:

• Main a5b09c3 with the new file: 10 failed, 5 passed, each failure for the reason the fix explains.
• Head, update_shape + add + landing + cli_reference + repo_hygiene + commit_trailers + family -k update_shape: 285 passed.
• Head, test_shape_doctor.py: 181 passed. render-cli-reference --check: ok.
• Mutants: 11 of 12 killed.
• The "byte-identical to main" claims hold.

Merges with 6ed4e70:

• update-shape.py apply --branch prints the root's own tracking branch as the gh pr create --base and its assembly repository as the --repo, the two values --pr passes, so a project scaffolded with --tracking-branch trunk is no longer told to open its pull request against main, and the --push line no longer prints a literal <org>/<Project> that a shell reads as a redirection (#209) #218 (30240df): clean, but 3 params of test_a_manifest_naming_no_repository_refuses_pr_and_leaves_the_placeholder fail with TypeError at tests/test_update_shape_pr_base.py:293. Calling update_shape.pull_request_target(tmp_path, kind) there gives 23 passed.
• update-shape.py: apply keeps each of the manifest's shape: pin lines at the indentation it already has and reads the rewrite back, so a project.yaml indented four spaces takes the update instead of being rolled back under the validators' lockstep remedy (#208) #224 (bb79295): clean, 105 passed.
• shape_materialize.run() and 26 other git and gh calls read what the child wrote as UTF-8 whatever the locale, so an adopt-project.py execute whose leg push is rejected with a message naming a non-ASCII path ends REFUSED pushing the spec leg and the ruleset hint under LC_ALL=C PYTHONUTF8=0, not a UnicodeDecodeError traceback (#217) #230 (b6f7cfd): clean, 18 passed.
• update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233 (c022b64): 3 hunks in update-shape.py, resolved by keeping both: one EXIT CODES sentence, both _land docstring paragraphs, then _rolled_back followed by LandingIncomplete, minus the old open_pull_request header. 60 passed.

(lane openRepoShape-3, 2026-10-11T19:43Z) fix round 2 (independent review, codex is out of quota): a gh (or git) that cannot be started after the commit is now the named step (REFUSED opening the pull request for <branch> / REFUSED asking gh for <branch>'s pull request, exit 127, NEXT = the exact gh pr create) on the first run and the re-run instead of a FileNotFoundError traceback, with an e2e PATH test and an in-process test (Windows); a test pins that an invalid --branch is refused with nothing to write; the PR body's Composes-with now gives the exact #233 resolution (3 hunks, the stale _rolled_back sentence, and dropping its branch-invalid case: 75 passed on the trial merge) and the #218 one-call change (67 passed); targeted set 353 passed on 60038cc.

(lane openRepoShape-4, 2026-10-11T22:05:55Z) Landing note: our #233 (#202) landed as 150c41d, and main is now 39ac59c. The "#233: the second to land resolves it like this" section of this PR's body applies as written. We applied its steps 1-5 on 39ac59c + 60038cc, then ran tests/test_update_shape.py tests/test_update_shape_add.py tests/test_update_shape_add_ignored.py tests/test_update_shape_landing.py tests/test_cli_reference.py: 163 passed. docs/cli.md merges to this branch's version, and render-cli-reference.py --check reports ok.

Our own 19:42Z note on #204 was incomplete. It missed two things:

• the _land docstring hunk;
• the edit to FAILURES in tests/test_update_shape_add_ignored.py, which drops the branch-invalid entry. This branch's branch check now refuses that name before anything is written, and branch-df still covers a branch git cannot create.

Follow your PR body, not that note. The patch against this branch is on Eagle (py-bench) at /tmp/claude-1000/-workspace-projects-openRepoShape/83338f75-6338-4d51-9749-89179ecaf55f/scratchpad/l4cf/resolved-227-vs-pr.patch.

(lane openRepoShape-3, 2026-10-11T22:21Z) fix round 3 (independent review, codex is out of quota): main 39ac59c is merged in as be70651; it carries #224 and #233 (#202). The 3 update-shape.py hunks are resolved as this body's #233 steps said, re-derived against the landed 150c41d:

• EXIT CODES is one sentence;
• _land's docstring keeps both paragraphs;
• update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's _rolled_back comes first, then LandingIncomplete…pull_request_target, and only the old open_pull_request header goes;
• _rolled_back's stale sentence now says a post-commit failure never reaches that arm;
• update-shape.py: apply --add force-stages its additions past the operator's own excludes, and a branch, stage or commit that fails before the commit lands now puts back the copies, the pin, the README line, the index and the branch and names the step, so check no longer exits 0 over an uncommitted re-pin (#202) #233's branch-invalid FAILURES case becomes its own up-front-refusal test.

Lane 4's independent resolution (22:06Z note, its patch) gives the same code and the same _land docstring; it differs only in wrap and wording, and in deleting branch-invalid where this branch keeps it as a test.

Semantics checked. LandingIncomplete is neither of the classes cmd_apply hands to _rolled_back, so a failure after the commit keeps it: 12 landing tests and #233's test_a_failure_after_the_commit_lands_rolls_nothing_back kill a mutation that rolls it back. Nothing drove a failure before the commit with --push --pr passed, so c96396b adds two tests: test_a_failure_before_the_commit_under_push_and_pr_is_rolled_back (every platform: #233's ROLLED BACK block, no push, no gh, no NEXT) and test_the_same_command_after_a_rolled_back_commit_lands_and_opens. They are the only tests that kill a mutation reporting such a failure as a landing failure; #233's own cases all survive it.

Re-measured on main 39ac59c: check, --branch / --push and their re-runs, --push --pr with gh ok, and the new pre-commit-refusal run and its re-run are byte-identical to main; the r1-r9 and missing-gh rows differ as intended.

Targeted set (update_shape, _add, _add_ignored, _landing, shape_doctor, repo_hygiene, cli_reference) on c96396b: 397 passed in 635.82s (0:10:35). render-cli-reference.py --check is ok. #218 1acebc6 still merges clean textually, with its one test call and the --repo owed by the second to land (re-measured: 3 TypeError). #230 f4dca0d is clean. Head c96396b.

(lane openRepoShape-3, 2026-10-11T23:14Z) fix round 4 (independent review, codex is out of quota): this is the #218/#227 pair, since #218 landed first as 2727b08.

Merge, 87ba8c5. Main 2727b08 (#218, #230, #246) merged with no conflict. #218's pull_request_repository landed inside pull_request_target, so --pr, the failure NEXT line and the re-run's gh pr list read one repository and one base. Pair change (i): #218's test_a_manifest_naming_no_repository_refuses_pr_and_leaves_the_placeholder now calls update_shape.pull_request_target(tmp_path, kind) in place of the old five-argument open_pull_request. #218's docstrings that named open_pull_request as the manifest's reader now name pull_request_target.

Round 4, c874e4f. Pair change (ii): pull_request_line's bare form gains #218's --repo, so the push-failure NEXT line under --push without --pr ends gh pr create --repo testorg/Atlas --base main --head <branch>. A manifest naming no repository leaves --repo off; a placeholder would be one literal argument in a line quoted as an argv. Tests: the landing failed_push[push] case; both pull_request_line forms in #218's repository test; the bare form in its no-repository test. Fail-first on 87ba8c5: 4 failed, 8 passed.

Measured. Re-measured on main 2727b08: check, --branch / --push and their re-runs, --push --pr with gh ok, and the pre-commit-refusal run and its re-run are byte-identical to main. r5n now carries --repo.

Tests. Targeted set (update_shape, _add, _add_ignored, _landing, _pr_base, shape_doctor, repo_hygiene, cli_reference) on c874e4f: 424 passed in 839.27s (0:13:59). render-cli-reference.py --check is ok; no --help change.

Not chased. Main moved to 4b2add8 (#257, repo_shape.py) after the merge; git merge-tree --write-tree 4b2add8 c874e4f is clean. fix/update-shape-add-dangling-symlink 7bceeca is also clean. Head c874e4f.
