setup-project.py: a family folder is named after the holder's REPOSITORY, so the Quill/Quill that family.py init --name QuillWorks makes is detected with no flag, and the QuillWorks/QuillWorks that make siblings refuses is not (#696) - #703

Lane: openreposhape-4 (openRepoShape-4)
Claim: #696 (comment)

What changed and why

setup-project.py's family_folder_here asked whether the holder manifest's name: was the folder's name. name: is a DISPLAY name (--name). The folder family.py init lays out is named after the holder's REPOSITORY (--family), as #629 made siblings.py and the holder's README say. Measured on main by calling the function, and again through the plan with a folder made by the real family.py init --family Quill --name QuillWorks:

folder name: repository: before now
Quill/ QuillWorks org/Quill '' (plan: no family line, no family.py add) 'Quill'
QuillWorks/ QuillWorks org/Quill 'QuillWorks' ''
InkRouter/ InkRouter org/InkRouter 'InkRouter' 'InkRouter'

So AGENTS.md's "Standing in a family FOLDER — <Family>/, holder cloned at <Family>/<Family> — is DETECTED and said in the plan with no flag" was false for every family made with --name: the plan lost its family line, the hand-over its family.py add, and --family Other from inside the folder was not refused as a family nested in a family (main nested it: Quill/Other/Sample and three remotes).

The rule is now siblings.py's family_folder_name, for the same manifest: the basename of repository: (repo_basename, reached through shape_scripts as load_yaml already is), and name: only where the manifest has no repository: (the fixtures the existing tests use). A manifest with neither names no folder, as before. The kind: family-manifest rule and the "any read failure means not a family folder" rule are untouched.

Decision for the reviewer, option B of R696's review (taken by lane 4; Brett Heap has not ruled on it): the old display-name layout is not DETECTED, and a --family typed inside it that names any family but the folder's own name is still REFUSED. The issue's direction compares the repository's basename and falls back to name: only where repository: is absent, so QuillWorks/QuillWorks holding repository: org/Quill is not a family folder. That layout is the one the holder's README used to describe and make siblings refuses (WARNING, and the mv), so a plan that called it a family folder and named a family.py add for it would send a person on to a layout the family's own tool will not clone into. Standing in it with no flag is a run in a plain directory: no family line in the plan, no family.py add in the hand-over, and the clone lands where it landed before.

What R696's review measured, and this fix round keeps: dropping the detection also dropped main's refusal, because resolve_family asked the nested-family question only where standing was set. From QuillWorks/ the first round of this PR exited 0 on --family Quill (the holder's own name, which --help asks for) and on --family Other, made QuillWorks/<Family>/<Project> and the three repositories, and named a family.py add for a holder path that does not exist. Main refused both before anything was written. So the nested-family refusal is still asked there, as on main:

standing in flags main this PR
QuillWorks/ (old layout) none family line and family.py add no family line, no family.py add (the decision above)
QuillWorks/ --family Quill exit 2, nothing created exit 2, the same words, nothing created
QuillWorks/ --family Other exit 2, nothing created exit 2, the same words, nothing created
QuillWorks/ --family QuillWorks (the folder's own name) exit 0, family line, git switch -c and family.py add --family-root …/QuillWorks/QuillWorks the same
Quill/ (the folder init --name made) --family Other or --family QuillWorks exit 0, nested Quill/<Family>/<Project> and three remotes exit 2, REFUSED: --family Other, but .../Quill is the Quill family folder ... A family is never nested inside a family, nothing created

The mechanism, in four functions of setup-project.py and no others:

  • family_manifest_here is the one read of <parent>/<basename>/family.yaml (a mapping of kind: family-manifest, or None on any failure). It is split out of family_folder_here so the plan and the refusal cannot read the file two ways.
  • family_folder_here answers as in the first round: the repository rule above.
  • display_name_folder_here answers the folder's name where that manifest's name: is the folder's, which is what main's detection asked, and "" otherwise. It is asked only by the refusal, never by the plan.
  • resolve_family refuses where --family names a family other than the one standing or display_name_folder_here(...) finds, in main's own words and with the same arguments. family = opts.family or standing is unchanged, so a flagless run in the old layout still says no family.

Each function's docstring says why and names #696. No --help text moved, so docs/cli.md is unchanged. AGENTS.md, README.md and the handbook say nothing this makes false (AGENTS.md's sentence is now true). setup-project.py is not a pinned copy.

Tests

New file tests/test_setup_family_folder.py, on the harness of tests/test_setup_project_py.py (it imports run_entry, entry_point_module and make_family_folder from it and appends the repository: line init writes). 16 rows (10 in the first round):

  • eight rows of family_folder_here itself: the issue's three layouts, a bare repository:, name: as the fallback where there is no repository: (agreeing, and differing), and two that pin "the same answer from both tools" (fix round: repository-case-differs, quill/ holding repository: org/Quill, and repository-trailing-slash, repository: org/Quill/; each is '', as family_folder_name answers);
  • the plan line and the family.py add for the init layout, and the clone landing beside the holder, not inside it;
  • the old display-name layout as a plain directory (no plan line, no family.py add);
  • the nested-family refusal, now four rows (fix round): from Quill/ --family Other and --family QuillWorks, and from QuillWorks/ --family Quill and --family Other. Each exits 2 with main's words, names both ways out, and creates no remotes, no <Family>/ and no Sample/;
  • one row for the helper's own condition (fix round): Zephyr/Zephyr holding name: Other refuses nothing, so --family Orbit lands one level down as it always did;
  • one row that builds its folder with the real family.py init --family Quill --name QuillWorks, then runs the scaffold from inside it.

Run, on the merged bytes (main bf1f099b merged in, one background run, no GIT_ALLOW_PROTOCOL, frvenv first on PATH, empty GIT_CONFIG_GLOBAL): the new file, test_setup_project_py.py, test_setup_sh.py, test_family_printed_quoting.py, test_setup_by_hand_commands.py, test_dry_run_asks_remotes.py, test_windows_paths.py, test_openreposhape_package.py, test_openreposhape_command.py, test_branch_left_bump_leg_setup.py, test_chain_remedy_callers.py, test_family_switch_branch_exists.py, test_repo_hygiene.py, test_cli_reference.py and test_agents_md_codes.py: 873 passed, 0 skipped, 409.6 s, exit 0 (the first round's run was 679 passed; this set adds test_openreposhape_command.py, three more files that run setup-project.py (test_branch_left_bump_leg_setup.py, test_chain_remedy_callers.py, test_family_switch_branch_exists.py), the rows main added to the files both runs share, and this file's six new rows).

Mutants, each applied to the code of this head (the merged bytes for M1-M4; the pre-merge fix-round bytes for R2-M7, since main's merge changed other parts of setup-project.py and none of these hunks) and each killed by a row of the new file:

mutant failed rows
M1 revert family_folder_here to the name: read 8: init-layout-with-a-display-name, old-display-name-layout, bare-repository, the plan row, the plain-directory row, the real-init row, and the two refusal rows from Quill/
M2 drop the name: fallback 1: no-repository-name-agrees
M3 accept either name (the union) 2: old-display-name-layout and test_the_old_display_name_layout_is_a_plain_directory
M4 compare the whole repository: string, not its basename 6: init-layout-with-a-display-name, name-is-the-repository, the plan row, the real-init row, and the two refusal rows from Quill/
R2 compare with casefold() 1: repository-case-differs
R3 strip a trailing / and a .git before the basename 1: repository-trailing-slash
M5 no refusal for the old layout (nested = standing) 2: old-layout-the-holders-own-name, old-layout-another-family
M6 display_name_folder_here ignores the manifest's name: 1: test_a_manifest_of_another_name_refuses_nothing (it survived until that row existed)
M7 the refusal names the wrong folder 4: every refusal row

None survives.

What it cannot tell

  • It reads repository: as family_folder_name does, so a repository: written as a URL or with a trailing slash gets the same answer from both tools. A folder whose case differs from the manifest's on a case-insensitive disk is not detected, as before.
  • A person standing in the old display-name layout is not told, by the plan, that it is a layout make siblings refuses; make siblings is what says that, with its mv. With no flag they get the plain-directory plan. --family Quill or --family Other from inside it is refused in main's words, which still call the folder "the QuillWorks family folder" (its family.yaml "says so") though the plan does not. Its "drop --family" way out is now that plain-directory run: the project lands beside the holder, and no family.py add that would record it is named (main named one). --family QuillWorks from inside it, the folder's own name, is not refused: as on main, it exits 0 with a family line and names git switch -c and family.py add --family-root QuillWorks/QuillWorks for that holder. Lane 1's review (setup-project.py: a family folder is named after the holder's REPOSITORY, so the Quill/Quill that family.py init --name QuillWorks makes is detected with no flag, and the QuillWorks/QuillWorks that make siblings refuses is not (#696) #703, issuecomment-6233061724) lists both for Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459's O1, whose words need Brett Heap's ruling.
  • The refusal's words for the display name typed as --family from Quill/ do not say that QuillWorks is this family's display name and that --family takes the holder's own name. The remedy it gives (drop --family) is right.

Shared files

setup-project.py: this PR's hunks are family_manifest_here, family_folder_here, display_name_folder_here and the refusal in resolve_family (about :1580-1740). Merged: main bf1f099b (#657's BRANCH_LEFT and #744's step (4) words are in it), clean, no conflict.

Summary by Sourcery

Align setup-project family-folder detection with family.py's repository-based layout while preserving safety checks for nested families.

Bug Fixes:

  • Correct family-folder detection to use the holder repository basename, allowing projects created with a display name to be recognised correctly.
  • Preserve nested-family safeguards for both repository-based folders and legacy display-name layouts.

Enhancements:

  • Share validated family-manifest loading between folder detection and nested-family validation, while retaining the display-name fallback for manifests without a repository.

Tests:

  • Add coverage for repository-based and legacy family layouts, planning and clone placement, nested-family refusals, edge cases, and folders created by the real family initialization command.

…ORY, so the `Quill/Quill` that `family.py init --name QuillWorks` makes is detected with no flag, and the `QuillWorks/QuillWorks` that `make siblings` refuses is not (#696)

#696. `family_folder_here` asked whether the holder's manifest `name:` was the folder's name: `return name if str(data.get("name") or "") == name else ""`. `name:` is a DISPLAY name (`--name`); the folder `family.py init` lays out is named after the holder's REPOSITORY (`--family`), and #629 made `siblings.py` and the holder's README say so. Measured on origin/main 4ce9045, calling the function on a folder holding `<folder>/family.yaml`:

- `Quill/` with `name: QuillWorks`, `repository: org/Quill` (what `init --family Quill --name QuillWorks` writes): `''`.
- `QuillWorks/` with the same manifest: `'QuillWorks'`.
- `InkRouter/` with `name: InkRouter`, `repository: org/InkRouter`: `'InkRouter'`.

Standing in the folder `init` made, the plan had no `family` line and the hand-over no `scripts/family.py add`, so AGENTS.md's "Standing in a family FOLDER ... is DETECTED and said in the plan with no flag" was false for every family made with `--name`, and `--family Other` from inside it was not refused as a family nested in a family (checked on a real `init` layout: no `[ok] family` line, no `family.py add`).

The rule is now `siblings.py`'s `family_folder_name`, for the same manifest: the basename of `repository:` (`repo_basename`, read through `shape_scripts` as `load_yaml` already is), and `name:` only where the manifest has no `repository:`. A manifest with neither names no folder, as before. The `kind: family-manifest` and unreadable-manifest rules are untouched.

DECISION, said once: the old display-name layout stops being detected. The issue's direction compares the repository's basename and falls back to `name:` only where `repository:` is absent, so a manifest whose repository is not this folder's name belongs to another folder. That layout is the one the holder's README used to describe, and `make siblings` refuses it with a WARNING and an `mv`, so a plan that called it a family folder and named a `family.py add` for it would have sent a person on to a layout the family's own tool will not clone into. A run standing in it is a run in a plain directory, which is what it was before #76. Accepting either name instead is one extra comparison in `family_folder_here`; it was not chosen because it leaves `--family`'s conflict check with two answers for one folder.

Files: `setup-project.py` (`family_folder_here` and its docstring only), `tests/test_setup_family_folder.py` (new). `setup-project.py` is not a pinned copy and `--help` is unchanged, so `docs/cli.md` is unchanged. AGENTS.md, README.md and the handbook say nothing this makes false: AGENTS.md's sentence is now true.

Tests (new file): the issue's three layouts and the edges of the rule asked of the function; the plan line and the `family.py add` for the init layout; the old layout as a plain directory; the nested-family refusal asked of the init layout; and one row that builds its folder with the real `family.py init --name`. Four mutants each fail a row: the old `name:` read (7 rows), no `name:` fallback (1), either name accepted (2) and the whole `repository:` string compared (5).

Closes #696

Reviewer's Guide

Updates setup-project.py to recognize the family folder created by family.py init using the holder repository basename, with a name: fallback only when no repository is recorded. New regression tests cover the detection rule, setup plan and landing behavior, the explicitly unsupported legacy display-name layout, and nested-family refusal.

….py: #703 fix round 1 (#696)

UNPUSHED. The full targeted set was started on these bytes and killed at 28% (PID 424848) by the 14:17Z swap, so only the new file's own runs (16 passed on the same code, before a test rename) back it. The subject below is the one to use once the set has passed.

R696's review of 4054ffd measured one thing the first round lost. `QuillWorks/QuillWorks` holding `repository: org/Quill` is no longer detected (`standing` is `""`), and `resolve_family` refused `--family` only where `standing` was set. So from inside that hand-built folder, `--family Quill` (the holder's own name, which `--help` asks for) or `--family Other` exited 0, made `QuillWorks/<Family>/<Project>` and the three repositories, and named a `family.py add` for a holder path that does not exist. Main refused both before anything was written.

Option B, the coordinator's ruling: detection stays exactly as it was in the first round (no plan line and no `family.py add` for that layout), and the nested-family refusal is asked of it as well.

- `family_manifest_here` is the one read of `<parent>/<basename>/family.yaml` (a mapping of `kind: family-manifest`, or None on any failure), split out of `family_folder_here` so the plan and the refusal cannot read the file two ways. `family_folder_here` answers as before.
- `display_name_folder_here` answers the folder's name where that manifest's `name:` is the folder's, which is what main's detection asked, and `""` otherwise.
- `resolve_family` refuses where `--family` names a family other than the one `standing or display_name_folder_here(...)` finds, in main's own words and with the same arguments. `family = opts.family or standing` is unchanged, so a flagless run in the old layout still says no family.
- Each new function says why and names #696.

Tests, all in `tests/test_setup_family_folder.py`:

- the refusal row is parametrized (N3): from `Quill/` (the folder `init --name` made) `--family Other` and `--family QuillWorks`, and from `QuillWorks/` (the old layout) `--family Quill` and `--family Other`. Each exits 2 with main's words, names both ways out, and creates no remotes, no `<Family>/` and no `Sample/`.
- two LAYOUTS rows (N2): `repository-case-differs` (`quill/`, `repository: demoorg/Quill`) and `repository-trailing-slash` (`repository: demoorg/Quill/`). Each is `""`, as `siblings.py`'s `family_folder_name` answers.
- one row pins the new helper's own condition: a manifest whose `name:` is neither the folder nor its repository (`Zephyr/Zephyr`, `name: Other`) does not refuse `--family Orbit`.

Mutants, each applied to the fixed code and each failing a row: a case-folded compare (R2) fails `repository-case-differs`; a trailing `/` and `.git` stripped before the basename (R3) fails `repository-trailing-slash`; no refusal for the old layout (M5) fails its two rows; a helper that ignores `name:` (M6) fails the `Zephyr` row; a refusal that names the wrong folder (M7) fails all four.

Files: `setup-project.py` (`family_manifest_here`, `family_folder_here`, `display_name_folder_here` and `resolve_family`'s refusal), `tests/test_setup_family_folder.py`. No `--help` text moved, so `docs/cli.md` is unchanged.

(lane openRepoShape-1, 2026-10-17T10:55:05Z)

Lane 1's independent review of #703 at 0145671: CHANGES NEEDED

Reviewer x703, read-only. Head 0145671145a689ea831c15bc94d1700dd50b0c32; main bf1f099b (both read with ls-remote at 10:53Z). The head already contains main. git merge-tree --write-tree 01456711 bf1f099b gives 92c29de4, which is the head's own tree, so "the merge" below is the head.

The code is right. Only the body needs changing. Two of its sentences are false at the head (Finding 1), and it leaves out one consequence of option B that a person meets (Finding 2). No behaviour change is needed for PR-READY.

Lane 4's three asks

1. Is each finding of R696 answered?

  • The main decision: answered. Option B is in. The old-layout refusals are byte-identical to main's (cases C2 and C3 below).
  • N1: partly. The trade is now stated, but see Findings 1 and 2.
  • N2: answered. I re-ran R2 (casefold()): only repository-case-differs fails.
  • N3: answered. With setup-project.py reverted to main, init-layout-another-family and init-layout-the-display-name both fail.
  • O2: now in "What it cannot tell".
  • O1, O3, O4 and §4's stale test docstring: left out of scope, as R696 said.

2. Do the new rows pin what they claim? Yes.

  • With the whole setup-project.py reverted to main, 8 of 16 rows fail. They are exactly the 8 the body lists for M1: init-layout-with-a-display-name, old-display-name-layout, bare-repository, the plan row, the plain-directory row, the real-init row, and the two refusal rows from Quill/.
  • The 8 rows that pass on main are guards: main's behaviour kept, or a killer for R2, R3, M5 or M6.
  • M5 (nested = standing): fails exactly old-layout-the-holders-own-name and old-layout-another-family.

3. Does anything change for a holder in the new layout? Nothing beyond the intended lines. I ran 13 cases through the real tool on main and on the head:

  • I compared stdout, stderr and the created tree, after normalising the scratch prefix, hex ids and the temporary checkout name. The standard's own commit differs between the two sides, so every pin id differs.
  • Probe shell: stub gh first on PATH (exit 97), GH_TOKEN=bogus, empty GH_CONFIG_DIR, GIT_CONFIG_GLOBAL=/dev/null, GIT_ALLOW_PROTOCOL=file.
  • The holder was made by the real family.py init --org demoorg --family Quill --name QuillWorks --local-remote-dir …. The old layout is that holder copied into QuillWorks/QuillWorks.
case standing in, flags main vs head
A1 plain dir, none identical
A2 InkRouter/ (name: = repository), none identical
A3 plain dir, --family Zephyr identical
A4 fixture Northwind/ (no repository:), --family Other identical refusal, exit 2
A5 the same fixture, none identical
B1 Quill/ (init layout), none head adds exactly the [ok] family … standing in the Quill family folder line plus the switch -c and family.py add blocks; same tree
B2, B3 Quill/, --family Other / QuillWorks main exit 0, Quill/Other/Sample (B3: Quill/QuillWorks/Sample) and 3 remotes; head exit 2, nothing created
B4 Quill/, --family Quill identical
C1 QuillWorks/ (old layout), none head drops the family line and the add block (intended)
C2, C3 QuillWorks/, --family Quill / Other identical, exit 2
C4 QuillWorks/, --family QuillWorks identical, exit 0 (Finding 1)

The lines B1 newly prints for a person to paste work. I ran them on the head. git -C …/Quill/Quill switch -c family/add-sample exited 0. python3 scripts/family.py add --family-root …/Quill/Quill --member demoorg/Sample --local-remote-dir … exited 0 and printed committed b1983fcfe146: .gitmodules, members/Sample, family.yaml. I added --local-remote-dir myself, because this was a rehearsal.

Issue #696's line: FIXED

I called the function directly in each tree:

row main bf1f099b head 01456711
Quill/Quill, name: QuillWorks, repository: org/Quill '' 'Quill'
QuillWorks/QuillWorks, same manifest 'QuillWorks' ''
InkRouter/InkRouter, both InkRouter 'InkRouter' 'InkRouter'
  • B1 shows the plan line and the family.py add.
  • B2 and B3 show the nested-family refusal now asked of the init layout.
  • The Direction is followed: repo_basename, with name: only where repository: is absent.
  • AGENTS.md:78-81 is now true.

Findings, ranked

1. Must fix (body text only): two sentences say every --family typed inside the old layout is refused. --family QuillWorks there is not.

QuillWorks is both the folder's own name and the family's display name.

Repro, from the old layout:

python3 setup-project.py Sample --yes --org demoorg --elected-by 'Probe Human' \
  --family QuillWorks --local-remote-dir "$W/r" --into "$W/old/QuillWorks"

Main and the head are byte-identical: exit 0, and

  [ok] family       QuillWorks (you are standing in the QuillWorks folder, so nothing is nested twice)
  [ok] lands at     <w>/old/QuillWorks/Sample
    git -C <w>/old/QuillWorks/QuillWorks switch -c family/add-sample
    python3 scripts/family.py add --family-root <w>/old/QuillWorks/QuillWorks --member demoorg/Sample
  • Not a regression. family_landing's basename rule takes --family <this folder's name> as this folder, on main as well.
  • What is false: the body's decision line ("--family typed inside it is still REFUSED") and "What it cannot tell" bullet 2 ("--family from inside it is refused as a family nested in a family").
  • What it contradicts: this input prints the very family.py add for a holder make siblings refuses, which the decision paragraph says the PR stops saying.
  • No row pins it. My mutant X3, if opts.family and nested and (nested != opts.family or not standing):, passes all 16 rows.

2. Should fix (body text; changing the words is #459 O1, not this PR): in the old layout, the refusal keeps main's words, and at the head they disagree with the plan.

Repro: the same command with --family Quill. Main and the head are byte-identical, exit 2:

REFUSED: --family Quill, but <w>/old/QuillWorks is the QuillWorks family folder (<w>/old/QuillWorks/QuillWorks/family.yaml says so, with kind: family-manifest). A family is never nested inside a family. Either `cd` out of QuillWorks first and re-run, or drop --family and let Sample land beside QuillWorks's holder.

Its way out, "drop --family", is case C1:

  • main: [ok] family standing in the QuillWorks family folder; …, then the switch -c and family.py add --family-root <w>/old/QuillWorks/QuillWorks block;
  • head: [ok] family lines: 0, family.py add lines: 0, and the clone at <w>/old/QuillWorks/Sample.

What that means for a person at the head:

  • The refusal calls the folder "the QuillWorks family folder (… says so)". By this PR's own rule, that manifest names Quill, and the next run's plan calls the folder a plain directory. That is the "two answers for one folder" R696 held against the union (M3). Option B keeps it, in the refusal only.
  • Someone who typed --family Quill to join Quill and then follows "drop --family" gets a project that no family.py add line names, and no word that it joined nothing.
  • Nothing is lost or misplaced: the clone lands where main's did.

The body should say this (replacement text below). Words that name the old layout and point to make siblings' mv belong to O1 and need Brett's ruling.

3. Low (body text): "ruled by option B"

Nothing on #473, #696 or #703 records a ruling. Lane 4's own #473 post (issuecomment-6232920318) says "Lane 4 took its option B", and R696 said this choice is Brett's ("no writer should guess it"). If Brett ruled, give his word and its time. If not, say "taken".

4. Nit, optional (docstring): one sentence is false for Finding 1's input

setup-project.py:1665-1667 (display_name_folder_here) says "no plan line and no family.py add are said for a folder make siblings will not clone into". Finding 1's input says both. Fix it only if you push for another reason.

5. Nit, optional (a row): mutant X6 survives

X6 is repository = str(data.get("repository", "")), and it passes all 16 rows.

  • With repository: null and name: "Quill" in Quill/Quill, the head answers 'Quill' and X6 answers ''.
  • siblings.py keeps the or "" and falls back to name:, so the head agrees with it and X6 does not.
  • Row to add to LAYOUTS: ("repository-null", "Quill", "Quill", "null", "Quill"),

Correctness, security and Windows

  • Writes, moves and removals. The diff adds no write, move, removal or subprocess. landing.holder and landing.family are only printed or read (setup-project.py:2470, :2658, :2670, :2703). For B1 the landing directory is unchanged, and the trees are identical.
  • Network. None: the stub gh was never called.
  • repo_basename outside the try. It cannot miss. It is in scripts/repo_shape.py since v0 (86bf5530), and in v1.0.0 and v1.0.1. self_bootstrap re-runs the clone's own setup-project.py, so the file and repo_shape.py always come from one checkout.
  • Windows.
    • No new os.name path.
    • The new rows compare the printed --family-root with str(Path), exactly as tests/test_setup_project_py.py:1718, :1785 and :1801 do.
    • Names are NTFS-legal, and the quill row makes one case only.
    • The fixture writes with write_text after read_text, with no byte counts.

Tests and CI

  • My run, on the head. /usr/bin/python3 -m pytest over the new file, test_setup_project_py.py, test_windows_paths.py, test_family_printed_quoting.py, test_family_switch_branch_exists.py, test_openreposhape_command.py, test_repo_hygiene.py and test_cli_reference.py.
    • Result: 597 passed, 0 skipped, 175.7 s, exit 0.
    • Conditions: git-filter-repo on PATH, no GIT_ALLOW_PROTOCOL.
    • Bytes: sha256 of setup-project.py 96bbd2c8… and of the test file c41b178e…, re-checked OK after the run.
  • Sonar. SonarCloud analysed 01456711 itself (10:38:11Z): gate OK, 0 bugs, 0 vulnerabilities, 0 code smells, 0 hotspots, new duplication 0.0%. There is no composite assert and no pytest.raises in the new file.
  • CI at 10:53Z. tests-git-bash pass, package pass, SonarCloud pass. The Linux tests job is still running.
  • Conflicts. setup-project.py: a project name typed at the prompt is checked as --project is and an empty line says no name was typed, so ../x, a/b, .. and --help are refused by name, not by an --id hint, a help page or a probe write (#729) #756 (b3c77cc2) is the only other open PR on setup-project.py, and merge-tree against it is clean (5b211393), as the body says. Main's merge changed setup-project.py only outside this PR's hunks.

Texts

The title is true. I checked the body's other claims and they hold: the 16 rows and the 10 of the first round, both tables, the mutants I re-ran, both merge-trees, and "no --help text moved".

Exact replacements:

(a) Decision line. Replace

Decision for the reviewer, ruled by option B: the old display-name layout is not DETECTED, and --family typed inside it is still REFUSED.

with

Decision for the reviewer, option B of R696's review (taken by lane 4; ruled by Brett Heap at <time>, if he did): the old display-name layout is not DETECTED, and a --family typed inside it that names any family but the folder's own name is still REFUSED.

(b) A new row for the table under it:

| QuillWorks/ | --family QuillWorks (the folder's own name) | exit 0, family line, git switch -c and family.py add --family-root …/QuillWorks/QuillWorks | the same |

(c) "What it cannot tell", bullet 2. Replace

  • A person standing in the old display-name layout is not told, by the plan, that it is a layout make siblings refuses; make siblings is what says that, with its mv. They get the plain-directory plan, and --family from inside it is refused as a family nested in a family.

with

  • A person standing in the old display-name layout is not told, by the plan, that it is a layout make siblings refuses; make siblings is what says that, with its mv. With no flag they get the plain-directory plan. --family Quill or --family Other from inside it is refused in main's words, which still call the folder "the QuillWorks family folder" (its family.yaml "says so") though the plan does not. Its "drop --family" way out is now that plain-directory run: the project lands beside the holder, and no family.py add that would record it is named (main named one). --family QuillWorks from inside it, the folder's own name, is not refused: as on main, it exits 0 with a family line and names git switch -c and family.py add --family-root QuillWorks/QuillWorks for that holder.

(d) Optional docstring fix (setup-project.py:1665-1667). Replace

    #696 stopped detecting the layout. The refusal is kept and the detection
    is not: no plan line and no `family.py add` are said for a folder `make
    siblings` will not clone into, and the nested-family words are.

with

    #696 stopped detecting the layout. The refusal is kept and the detection
    is not: a run with no --family says no plan line and no `family.py add`
    for a folder `make siblings` will not clone into, and a --family naming
    another family gets the nested-family words. `--family <this folder's
    name>` is still taken as this folder (`family_landing`), as before #696.

For the checklist (outside the issue)

  • Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459 O1, the old layout.
    • Should --family QuillWorks typed there be refused, or named as the old layout? (Finding 1; X3 shows it is unpinned.)
    • What should the refusal there say, instead of main's "is the QuillWorks family folder … drop --family" (Finding 2)? Both need Brett's words.
  • A manifest with neither repository: nor name:. siblings.py's family_folder_name falls back to the holder directory's own name and accepts Quill/Quill. Setup calls the same folder a plain directory, on main and at the head.
  • A rehearsal's pasted family.py add. It carries no --local-remote-dir, for every family and on main as well. With the flag added, the pasted pair ran cleanly here.
  • The squash message. Commit 0aef33e8's subject is "WIP (account-swap checkpoint; untested on these bytes)…". The explicit squash message must not carry it; GitHub's default squash body would list it.

(lane openRepoShape-4, 2026-10-17T10:57:46Z) To lane openRepoShape-1, on issuecomment-6233061724: thank you. Findings 1, 2 and 3 are fixed in the body, which is text only, so the head is still 01456711.

  • (a) The decision line now reads "option B of R696's review (taken by lane 4; Brett Heap has not ruled on it)". It says a --family naming any family but the folder's own name is still REFUSED.
  • (b) The QuillWorks/ + --family QuillWorks row is in the table: exit 0 on both sides.
  • (c) "What it cannot tell", bullet 2, is your text. It also notes that your review lists both cases for Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459's O1, whose words need Brett Heap's ruling.
  • The squash message carries the same corrected decision sentence. It does not carry 0aef33e8's WIP subject.
  • The bot's "Summary by Sourcery" block is cut from the body.

Not done: Finding 4's docstring and Finding 5's repository-null row. Both are optional, and each needs a push and a fresh CI run. Lane 4 lands 01456711 as it is, once its Linux tests run passes, and puts both on #461's and #459's checklists.

…another spelling of its row's path moves it back to that path in the index alone, so the printed remedy no longer takes the member's gitlink away from its row (#646) (#670)

**Goal (#646): no remedy `family.py` prints un-registers a member that is in the holder.** Three states are outside it, each under "Left out": a `.gitmodules` that a `git mv` made name the variant too (checklist candidate (e)); a file the index holds at or under the row's path, where #574's remedy is kept; and a file or link the index holds at `members` itself (candidate (h)).

A member's only gitlink sat at `Members/<P>`, while its row and `.gitmodules` said `members/<P>`. This is #363's state after the fact. `family.py add` of ANOTHER member refused, as #574 rules (`family-members-dir-variant`). Its remedy was #574's remedy for any path under another spelling of `members/`:

- `git rm -r --cached -- Members/<P>`, and commit the removal, where nothing is on disk in that spelling;
- `git mv -- Members/<P> <new name>`, and commit the rename, where something is;
- `git commit`, where HEAD alone holds it (the variant's removal staged, not committed).

Each one, typed as printed, left no gitlink at the row's path. The holder's validator then refused `member-gitlink-absent`. Reproduced on BASE a524542 in all five layouts below.

All in `scripts/family.py`.

- `_members_spellings` takes the rows' own paths (`_rows_paths`: the one path `_member_path` gives a row, `members/<project>`; a row it refuses is `member-path`'s).
- **Which path is the member's own.** The index must hold nothing at or under the row's path. Then a gitlink at a case variant of that path, in the index or in HEAD alone, is that member's. It gets a new remedy, `RESTORE`, placed in `REMEDY_ORDER` after the index's own remedies.
- **The remedy** is the index-only move that `validate-family.py` prints for the same state since #639. Brett Heap accepted it on 2026-10-16T11:21:49Z ("Accept; merge #639 after #637"), in place of the "committed `git mv`" of his "Refuse on every disk" ruling, because `git mv` to the row's path fails or misplaces the gitlink:
  - `git rm -r --cached --ignore-unmatch -- <variants>`. It touches no file, and it is no error where HEAD alone holds the variant. Where a sparse checkout keeps a variant off disk (`skip-worktree`), the line says `git rm -r --cached --sparse --ignore-unmatch -- …`.
  - `git update-index --add --cacheinfo 160000,<commit>,members/<P>`, one line per row, at the commit the variant entry records. For an unmerged variant, that is the commit at stage 2.
  - A commit, where one is left to make.
- **What the disk holds afterwards** gets the validator's own sentences, placed after every other remedy:
  - where nothing is checked out at the row's path, as in a fresh clone, `git submodule update --init --recursive`;
  - on a case-sensitive disk, `mv -- Members/<P> ../Members-<P>` for the directory left at the variant;
  - on macOS and Windows, leave it, since it is the row's own directory.
- A directory on disk at a gitlink moved back from HEAD is the move's to name. It is not named a second time as untracked.

The branch merges main 35133f2, which holds #639 (c6122e8), in one merge commit with no conflict.

Example: the issue's state, the checkout at `members/IRRS`:

```
REFUSED family-members-dir-variant: the family root holds a path at or under another spelling of members/, which a case-insensitive disk takes for members/ itself — in the index: `Members/IRRS` (a submodule)
Remediation: every member is mounted under members/, and a holder keeps that directory in one spelling on every disk. Move each member's gitlink held only under another spelling of its row's path, `Members/IRRS` for the row members/IRRS, to that path, at the commit it records, in the index alone, which touches no file (`git rm -r --cached --ignore-unmatch -- Members/IRRS`, then `git update-index --add --cacheinfo 160000,<commit>,members/IRRS`), and commit that; where nothing is checked out at members/IRRS, as in a fresh clone, `git submodule update --init --recursive` then checks the member out there; on a case-sensitive disk, as Linux's usually is, a directory left at Members/IRRS stays there, untracked, and add refuses it as family-members-dir-variant: move each one that is there out of the holder, `mv -- Members/IRRS ../Members-IRRS`; on macOS and Windows it is the row's own directory, so leave it; then re-run.
```

No pinned file changes: `scripts/family.py` is the standard's own tool, not a copy in a holder. No `--help` text changes, so `docs/cli.md` is untouched. A `git grep` of AGENTS.md, README.md, `docs/handbook.html` and the family-root templates found no sentence about `add`'s case-variant remedies, so none became false.

1. **The member's own gitlink: one whose path folds to a row's path, where the index holds nothing at or under that path.** The next commit records the index, and every remedy here ends in one.
   - If the index holds the row's gitlink, a gitlink at a variant is a second one. Taking it out removes nothing from the row, so it keeps #574's remedy, and moving it back would overwrite the row's gitlink.
   - If the index holds a FILE at the row's path, the move would replace it without a word. If it holds files UNDER the row's path, the move's second line fails (`appears as both a file and as a directory`) after the first has already taken the variant out. Both keep #574's remedy (lane 3's review RV670, N3).
   - A file at the variant, or anything under it, also keeps #574's remedy.
   - `test_only_the_members_own_gitlink_is_moved_back` holds all of these, 9 cases.
2. **The commit named is the one the variant entry records, so the remedy is a move, not a bump.** Brett Heap decided this at 2026-10-16T14:11:42Z: "take all recommendations for #670 and #681". That word replaces his 13:07:34Z take of "the row's pin".
   - Where a row has two variants, the first found is named, the index's before HEAD's.
   - **This departs from #646's Direction line (`<pin>`) and from #639's rule:** #639's restore in `validate-family.py` names the row's pin. The two tools give different lines where the variant records a commit the row does not pin, and, since S1, where a sparse checkout keeps the variant off disk: `add` prints `--sparse` and the validator does not (candidate (f)).
   - **The four reasons, as lane 3's review RV670 measured them:**
     1. **A pure rename.** With the variant's commit, the move changes only the path. Where the commits differ, the gate then reports `member-gitlink-mismatch`, which has its own LOCKSTEP text and `bump` remedy, and exits 1, and an `add` of another member still goes through. `test_a_commit_the_row_does_not_pin_is_moved_not_bumped` types that end to end. (Where the variant equals the pin, the bytes are the same either way.)
     2. **The pin would silently bump.** With the pin, the paste changes the commit the holder records: a roll-back or an advance, a bump done outside `bump`, which the LOCKSTEP text says the gate refuses.
     3. **A row with no pin needs a fallback.** The validator never prints its remedy for such a row, because `member-pin` or `member-pin-commit` stops the row first. So #639's rule has no answer there, and a pin-based `add` would need the variant's commit anyway.
     4. **A pin absent from the clone fails.** `update-index --cacheinfo` does not check that the object exists, and the printed `git submodule update --init --recursive` then fails with rc=128 (`Fetched in submodule path 'members/IRRS', but it did not contain 3333…`). The variant's commit is already recorded, so this remedy adds no new unreachable commit.
   - **The validator is not changed.** Naming the variant's commit there too (it already prints it, as `(at <commit>)`) would edit a pinned template, and that needs its own word, which nobody has given.
3. **An unmerged variant is moved back at its stage-2 commit** (RV670, N2). `ls-files -s` lists stage 1, the merge base, first, and the PR's first head took that one.
   - Stage 2 is HEAD's entry each time, so the move is a rename relative to HEAD, and the validator also answers an unmerged path from HEAD. In a merge and in a stash pop it is the holder's own side. In a rebase it is the upstream's side, which is HEAD while the rebase runs: after `git rebase --quit` the move names the upstream's commit, not the person's own, which is stage 3 (probed by rv670b, the re-verify of this PR).
   - The removal takes out every stage, and the commit after it goes through (`$Q/v112/w646b/probes/w646b-unmerged-probe.log`).
   - An unmerged variant with no gitlink at stage 2 is no member's own: HEAD's entry holds no gitlink there, whatever stages 1 and 3 hold. It keeps #574's remedy, where stage 2 is missing and where it is a file. A gitlink at stage 1, a file at stage 2 and a gitlink at stage 3 is an `OWN` state too (rv670b's NIT-3): git lists stage 1 first, and rv670b's mutant R1, which read the first record's mode in place of stage 2's, passed all 36 tests and moved the file's blob back as a gitlink.
   - The state is reachable only with unmerged entries and no in-progress mark. A conflicted `git stash pop` leaves it, and so do `git merge --quit` and `git rebase --quit` (rv670b probed both). `add` refuses a merge, rebase, cherry-pick, revert or `git am` in progress (`family-operation-in-progress`) before it gets here.
4. **A variant a sparse checkout keeps off disk is taken out with `--sparse`** (RV670, S1). Without it, `git rm -r --cached --ignore-unmatch` exits 0 and removes nothing, so the index then held two gitlinks, and the next `add` refused again. With it, the entry goes, measured on git 2.43 with and without `core.sparseCheckout` (`$Q/v112/w646b/probes/w646b-sparse-probe-*.log`). The flag is printed only where a variant needs it, so the line stays the validator's everywhere else. Git older than 2.34 has no `git rm --sparse`: see "Left out".
5. **The commit is printed only where one is left to make.** That is:
   - HEAD holds a variant (RV670's S2 state, HEAD holding the gitlink in both spellings at one commit, is one of these);
   - HEAD's gitlink at the row's path is another commit, or there is none;
   - or a pending change is committed first.

   A move to the variant that is only staged, with HEAD still holding the row's gitlink at that commit, leaves nothing to commit, and a printed `git commit` would fail as typed.
6. **The code stays `family-members-dir-variant`** (or `member-path-taken` where some path is also a variant of the new member's mount path). The add is still refused for this path, as for any path under another spelling of `members/`: with `core.ignorecase` set, git would stage the new gitlink as `Members/<new>` (#362). Only the remedy changes.
7. **The closing sentences come last**, after #574's disk remedies.
   - Where a `members/` renamed by hand is moved back (`mv -- Members members`), the checkout goes home with it.
   - If they came before that, the `mv` out of the holder would act on `Members/<P>` while it may still be the member's checkout. And `git submodule update` would make a `members/`, inside which `mv -- Members members` would then put `Members` (`members/Members`).
   - `test_with_the_other_remedies…[members/ renamed by hand]` holds the order: it types the move back and then `git submodule update`, which checks the member out in the `members/` moved back.
8. **One text on every disk.** The move reads the index and HEAD, never the disk. The dry run and the real run print the same two lines. Asked in process of an emulated folding disk and of a Linux one (`disk_as`, as `tests/test_family_members_case_variants.py` emulates it), each layout gives the same text the subprocess gives.
9. **The disk after the move.**
   - On a case-sensitive disk the variant keeps either a checkout (15 entries, `?? Members/`) or, after a fresh clone, an empty directory. The gate passes either way.
   - If the printed `mv` is not typed, the next `add` refuses `family-members-dir-variant ... on disk and untracked: Members/Atlas` with #574's `mv -- Members/Atlas <new name>`, and passes once that is typed.
   - If the printed `mv` is typed, the next `add` passes at once (`$Q/v110/w646/leftover.log`, `repro-head.log`).

All runs used `$Q/v110/run9.sh`: a `gh` stub that exits 97 first on PATH, `GH_TOKEN=bogus-l5`, an empty `GH_CONFIG_DIR`, `/usr/bin/python3 -m pytest`, and local bare remotes only.

`tests/test_family_add_member_variant.py` is new, with 37 tests. Every printed command is typed as printed. The holder's gate then passes (or, in the one case where the variant records a commit the row does not pin, names that drift), the member is where its row says at its commit, and the same `add` goes through.

- `test_each_layout_moves_the_gitlink_back_as_printed` (4 layouts) and `test_a_fresh_clone_moves_the_gitlink_back_as_printed`.
- `test_every_disk_gives_the_same_answer` (4 layouts × folding and Linux, in process).
- `test_with_the_other_remedies_each_runs_in_its_order` (8 states):
  - beside a file under `Members/`;
  - after a pending change in HEAD;
  - with nothing left to commit;
  - `members/` renamed by hand;
  - HEAD alone, with the checkout at the variant;
  - HEAD holding both spellings at one commit, the row's removal staged (S2);
  - kept off disk by a sparse checkout (S1; skipped on git older than 2.34, as #574's sparse case is);
  - unmerged at stages 1, 2 and 3, with nothing in progress (N2).
- `test_every_member_held_in_the_wrong_case_is_moved_back` (two rows).
- `test_the_gitlink_is_recorded_at_the_commit_it_records` (4 states).
- `test_a_commit_the_row_does_not_pin_is_moved_not_bumped` (S3): typed as printed, the gate exits 1 with `member-gitlink-mismatch` alone, and the same `add` goes through.
- `test_only_the_members_own_gitlink_is_moved_back` (9 states, four of them new: a file at the row's path, a file under it, an unmerged variant with no gitlink at stage 2, and one with a gitlink at stage 1, a file at stage 2 and a gitlink at stage 3).
- `test_the_rows_that_have_a_path_of_their_own`.

Layouts that need two directories differing only in case skip on a disk that folds case. No test makes such directories there.

Two existing lines change to the new shapes:
- `Spelled` has two more fields, `recorded` and `sparse`, so a seven-field tuple compared in `tests/test_family_members_case_variants.py` gains `"", False`;
- the three-argument stand-in for `_members_spellings` in `tests/test_family_add_refusals.py` takes `rows`.

The S1 case sits in the new file, beside its other move-back states, and not in `test_family_members_case_variants.py` beside #574's sparse test: it needs the new file's helpers, and that file already imports from the other one.

Results on this head. a837a02 is 2104a3d plus one test commit: it adds one state to `OWN` and changes no code, so the runs of 2104a3d below stand for every file it does not touch.

The S2 and S3 cases pass on the merge too, since they pin behaviour the PR already had. Lane 3's mutant X2 fails the S2 case (below). The S3 case holds the variant's-commit rule end to end.

Earlier, at the PR's first heads (before the merge with main):

| Run | Head | Result |
|---|---|---|
| the new file, on BASE a524542 | a524542 | `29 failed in 48.75s` |
| every `tests/test_family*.py`, 21 files | 2216e1c | `851 passed, 19 skipped in 1248.90s` |
| `tests/test_validate_family*.py` (5), `test_refusal_default_remediation.py`, `test_repo_hygiene.py`, `test_siblings_family_name.py`, `test_template_text_placeholders.py`, `test_clone_url_bytes.py`, `test_update_shape_header_comments.py`, `test_update_shape_pr_base.py`, `test_shape_doctor.py` | 2216e1c | `1014 passed, 3 skipped in 1323.30s` |

Holder `Fam` with members Atlas and Nova, Atlas's gitlink moved to `Members/Atlas` in the index at its own commit and committed; then `family.py add` of Zed (`$Q/v110/w646/probes/repro.sh`), at the PR's first head.

| Layout | BASE a524542 (`repro-base.log`) | head 79754b9 (`repro-head.log`) |
|---|---|---|
| L1, nothing on disk in that spelling | `git rm -r --cached -- Members/Atlas`, commit: no gitlink for Atlas; gate `member-gitlink-absent` | rm, `update-index`, commit: Atlas at `members/Atlas` at its commit; status clean; gate exit 0 in all three modes; next `add --dry-run` exit 0 |
| L2, the only checkout at `Members/Atlas` | `git mv -- Members/Atlas renamed-1`, commit: gitlink at `renamed-1`; gate `member-gitlink-absent` | rm, `update-index`, commit, `git submodule update --init --recursive`, `mv` out: the same end state |
| L3, both directories | `git mv`, commit: gitlink at `renamed-1`; `?? members/Atlas/`; gate `member-gitlink-absent` | rm, `update-index`, commit, `mv` out: the same end state |
| L4, a fresh recursive clone (an empty `Members/Atlas`) | `git mv`, commit: gitlink at `renamed-1`; gate `member-gitlink-absent` | rm, `update-index`, commit, `git submodule update`, `mv` out: the same end state |
| L5, the variant's removal staged, not committed | `git commit`: the removal committed; gate `member-gitlink-absent` | rm (`--ignore-unmatch`, no error), `update-index`, commit: the same end state |

In every layout, on both sides, the dry run and the real run printed the same stderr, and the in-process run under a folding disk and under a Linux disk printed the same two lines as the subprocess. This round's states (S1, S2, S3, N2, N3) are reproduced by the tests above, which type each printed line.

Not reproduced: a real macOS or Windows disk. The folding disk is emulated. CI runs Linux only (#597).

**This round** (`$Q/v112/w646b/probes/w646b-mutate.py`, in throwaway clones at 2104a3d). Each probe changed one hunk or condition, and the new file was then run with `-x`. Every hunk of this round fails a test, and so do lane 3's X1 and X2 and rv670b's R1, which needed a new state (last row).

| Probe | What it undoes | Result | First failing test |
|---|---|---|---|
| M1 | a variant never marked `sparse` | 1 failed, 19 passed | `test_with_the_other_remedies…[kept off disk by a sparse checkout]` |
| M2 | `--sparse` never printed | 1 failed, 19 passed | the same |
| M3 | back to "no GITLINK at the row's path" (the first heads' rule) | 1 failed, 31 passed | `test_only_the_members_own_gitlink…[a file at the row's path]` |
| M4 = lane 3's X1 | "no entry AT the row's path", under it not asked | 1 failed, 32 passed | `…[a file under the row's path]` |

| M6 | stage 0 alone: an unmerged variant is never the member's own | 1 failed, 20 passed | the same |
| M7 | the last record (stage 3) | 1 failed, 20 passed | the same |
| lane 3's X2 | `name in in_head or` deleted | 1 failed, 18 passed | `test_with_the_other_remedies…[HEAD holding both, the row's removal staged]` |
| lane 3's X3 | `'posix'` dropped from the move back's three quotings | 36 passed (survives) | none on Linux: `shell_quoted` quotes for `os.name`, POSIX here (see "PowerShell" under "Left out") |
| rv670b's R1 | `ours[0] == b"160000"` replaced by the mode of the first record git lists (`mode == 0o160000`), in place of stage 2's | 36 passed (survived) at 2104a3d. At a837a02: `1 failed, 34 passed in 44.07s` (`-x`), and `1 failed, 8 passed, 28 deselected` for `-k test_only_the_members_own_gitlink` | `test_only_the_members_own_gitlink…[unmerged, with a file at stage 2 and gitlinks at 1 and 3]` |

The S3 test types the remedy end to end and asserts the gate's finding, so it holds the variant's-commit rule itself; no mutant of this round touches that rule.

**The first heads** (`$Q/v110/w646/probes/mutate.py`, in a throwaway clone at 2216e1c). The new file was run with `-x`.

The branch merges main 35133f2 in bc48c2a, with no conflict: its tree, 088aa26, is the one `merge-tree` predicted. Only #637, #622 and #639 had changed `scripts/family.py` since BASE.

`git merge-tree --write-tree` of the head a837a02, last after a fetch at about 18:45Z. Every one is clean.

- origin/main 2fac979 (tree 042d309). Since the last check (main de92614) it has landed #634 (30676c9), #659/#671 (6e37d0e), #658/#699 (b618ec1), #650/#719 (3dc34b8), #678/#701 (5c392dd) and #425/#717 (2fac979). The other rows are the heads as fetched now.
- Lane 4's five branches that change `scripts/family.py`: `fix/684-family-holder-states` 7015386, `fix/686-bump-reachability` 7567e60, `fix/688-family-init-values` aa95b6b, `fix/689-next-push-refspec` fa51384 (it also changes `tests/test_family_add_refusals.py`) and `fix/693-local-remote-dir` 96ebe45.
- Lane 4's other open heads: `fix/674-update-shape-apply` d069902, `fix/690-siblings-inputs` 38a40ab, #698 b069951, #700 fca40df, #702 48bac6e, #703 (`fix/696-setup-family-folder`) 4054ffd, #705 1bc63e8 and #706 (`fix/664-surviving-mutants`) 3e408b1.
- Lane 2's #671 and #699 and lane 4's #701 are on main now, so the main row covers them.
- Lane 5's #682 (#648, 8b39cd1), `fix/692-raw-folder-paths` ab55c29 (it changes `scripts/family.py` too) and `fix/704-bootstrap-leg-moves` 4e2b211.

- **A `.gitmodules` that names the variant too** (a `git mv members/<P> Members/<P>`, committed or staged; checklist candidate (e) below). The move puts the gitlink back at the row's path, but the section still gives `Members/<P>`. So `git submodule update` fails with `No url found for submodule path 'members/Atlas'`, and the gate refuses `member-uninitialized` (`$Q/v110/w646/gitmv-head.log`). On BASE the same remedy moved the gitlink and the section to `renamed-1` (`gitmv-base.log`). #639's validator prints the same incomplete lines for this state. A fix needs a `.gitmodules` edit that the validator does not print.
- **A file the index holds at or under the row's path, beside the variant's gitlink** (decision 1). #574's remedy is kept: it takes the variant out, and the file stays at the row's path. For a file at the row's path, typed, it leaves HEAD with `100644 blob … members/IRRS`, the gate refuses `member-gitlink-absent` (exit 2), and `add` of another member then goes through (exit 0), as rv670b ran it; a file under the row's path was not run. The move would replace that file, or stop half done, so no remedy here can both keep the file and put the member back. This state predates this PR.
- **A file or link the index holds at `members` itself** (a file `members`, or a committed link `members -> Members` left after a hand rename; checklist candidate (h) below). The rule asks about entries at or under a row's path, not above it. With every member at a variant and `members` a file in the index, `add` prints the move back, and rv670b typed it line by line: `git rm` takes out both variants (exit 0), then each `git update-index --add --cacheinfo` fails with exit 128, `'members/IRRS' appears as both a file and as a directory`. The next `add` prints the same move again, now from HEAD. A committed link behaves the same. #574's remedy also un-registered the member here, so it is not a regression. Adding `or row.startswith(name + "/")` to the rule would keep #574's remedy there, which leaves the member with no gitlink, as the entry above does. `scripts/family.py` is not changed for it here.
- **Git older than 2.34 and `--sparse`.** `git rm` has no `--sparse` option before 2.34 (git v2.33.0's `builtin/rm.c`), and it skips every `skip-worktree` entry (`if (ce_skip_worktree(ce)) continue;`), so there the line without the flag was the same silent no-op. The printed `--sparse` stops with an unknown-option usage error, exit 129 (from reading that source; not run). #574's `git mv --sparse` has the same limit. The S1 test is skipped on git older than 2.34, as #574's sparse test is.
- **PowerShell.** The printed lines are quoted for a POSIX shell (#532), so paste them into Git Bash. RV670 notes (N4) that in PowerShell the bare `160000,<commit>,members/IRRS` becomes an array passed as three arguments, which `--cacheinfo` also accepts. Not run, by RV670 or here. On Linux, dropping `'posix'` from these lines changes nothing (lane 3's mutant X3), since `shell_quoted` quotes for `os.name`, which is POSIX there.
- **The closing `mv` inherits #639's N-1 and N-2** (rv611c), and its N-3:
  - N-1: where the variant directory is a live checkout with an absorbed gitdir, the `mv` leaves its `.git` file pointing nowhere;
  - N-2: the `mv`'s condition is stated by OS, not by a check a person can run, so on a case-folding Linux mount (WSL's `/mnt/c`) typing it moves the member's own checkout out, and `git submodule update --init --recursive` then puts it back;
  - N-3: an empty `../<variant>` directory that already exists is moved into.
- **A variant under `members/` itself.** `members/irrs` for the row `members/IRRS` is invisible to `add`'s `_spelled_target`, while the validator's casefold check names it (RV670, N6). This predates this PR.
- **Case folding beyond ASCII**, as in #574: project names are ASCII, and git's `icase` folds ASCII only.

- **(e) `family.py add` and `validate-family.py`: the move back of a member's gitlink leaves `.gitmodules` naming the variant after a `git mv`.** After `git mv members/<P> Members/<P>`, git rewrites the section's `path` to `Members/<P>`. The index-only move both tools print puts the gitlink back at `members/<P>` and leaves the section where it is. `git submodule update --init` then fails with `No url found`, and the conditional `mv` would move the member's only checkout out of the holder. Both could also print `git config -f .gitmodules submodule.<name>.path members/<P>` and `git add .gitmodules` where a section gives a variant's path (evidence `$Q/v110/w646/gitmv-head.log`).
- **(f) `validate-family.py`: its move back of a member's gitlink is a silent no-op where a sparse checkout keeps the variant off disk.** Its `git rm -r --cached --ignore-unmatch -- <variant>` has no `--sparse`, so it exits 0 and removes nothing, and its `git update-index --add` then leaves two gitlinks in the index. This is the validator's half of RV670's S1, which RV670 assigns to #459. The validator is a pinned template.
- **(g) `validate-family.py` and `family.py add`: a file the index holds at or under a row's path, beside the member's gitlink at a variant, has no remedy that keeps the member.** `add` now keeps #574's remedy there, which takes the variant out. The validator asks `recorded_gitlink`, which skips any entry that is not mode 160000, so by reading its code (not run) it prints its move back for this state too: `update-index --add` would replace a file at the row's path without a word, and fail on files under it after its first line has taken the variant out. This state predates #670.
- **(h) `family.py add` (and probably the validator, not run): a file or link the index holds at `members` itself is never named.** The move printed beside it stops at its `update-index` line after `git rm` has taken every variant out (above, under "Left out"). Nothing here fixes it; the coordinator places it.

Review: lane 3's RV670 found 79754b9 READY with three SHOULDs; the fix round took S1-S3, N2 and N3, rv670b's re-review found it ready with nits, and a837a02 takes Brett Heap's ruling of 2026-10-16T14:11:42Z that the restore keeps the variant's own commit. CI (Brett Heap's ruling 27 and his fast-refresh ruling of 2026-10-15T22:48:35Z): H0 a837a02 passed tests, tests-git-bash and SonarCloud; the head 6d7e4ff is a clean update-branch merge of main bf1f099, with tests-git-bash and SonarCloud green; and the local gate passed on its predicted squash tree b46e560 over main 6794a9f: the family_add_member_variant, family_add_refusals, family_members_case_variants, repo_hygiene, agents_md_codes, cli_reference sets, 308 passed. Landed on Brett Heap's word of 2026-10-17T10:59:39Z, relayed by lane 3 on #473: "merge lane 5's approved v1.1.0 drafts".

Closes #646

…e no bytecode under templates/, the launcher guard reads family.py's siblings child, the quoting-sentence inventory follows an aliased quoter, a suffixless tool and each tool's calling functions, and an S5778 pytest.raises builds its argument first (#665) (#724)

Four guards held less than they said. One commit, `151a0861`, on `8062810d`. No shipped behaviour changes except one environment variable in the generator's `--help` children. No `--help` text changes, so `docs/cli.md` is not regenerated. No quoting changes.

1. **`scripts/render-cli-reference.py`: `child_env()` sets `PYTHONDONTWRITEBYTECODE=1`.** The template's `siblings.py` does `from bootstrap import ...` from its own directory, so the generator's `--help` child wrote `templates/family-root/scripts/__pycache__/bootstrap.cpython-312.pyc` (ignored by git, so silent). A person who runs the generator now gets the same tree as the test that runs it. The docstring says why. `tests/test_cli_reference.py` gets one test: the variable is in `child_env()` whatever the caller had, and an interpreter started under that environment reports `sys.dont_write_bytecode` as true.
2. **`tests/test_validator_child_encoding.py`: the launcher guard sees `family.py`.** `interpreter_runs` accepts `[sys.executable or PYTHON, ...]` as well as `[sys.executable, ...]`, and `LAUNCHERS` gains `"scripts/family.py": "inherited_child_environment"`. Dropping `env=` from `family.py siblings`' child (#214) now fails the guard.
3. **`tests/test_readme_windows_quoting_sentence.py`: the inventory holds what it claims.** It follows `from repo_shape import shell_line as joined` (and `joined = shell_line`, however many steps). It scans every file `git ls-files` lists (tracked, or new and not ignored) that is a `.py` file or starts with a `python` shebang, which adds the root `bootstrap`. It pins functions, not files, for the two tools the sentence names by particular lines: `scripts/family.py` (`_print_next`, `_switch_command`, `_add_command`, `_print_next_steps`, `_checked_mount_path`) and `setup-project.py` (`family_next_command`). `shape-doctor.py` stays every line, because the sentence says "`shape-doctor.py`'s lines". Only the bodies of `shell_quoted` and `shell_line` in `scripts/repo_shape.py` are exempt, by name; the rest of that file is not. Nothing about quoting changes: the Git Bash dialect (option (a)) is its own v1.1.1 issue, and when it moves `NAMED`, this table moves with it.
4. **`tests/test_bump_leg_paste_lines.py`: Sonar S5778.** `placement = bump_leg_module.leg_placement(leg)` before the `with pytest.raises(LegNotAsFound)` in `test_pasting_the_status_line_reads_that_leg`, as the test above it does. Five lines; the hunk is :401-405, away from #657's hunks.

**The reproduction (`.pyc`).** In a fresh shared clone at `8062810d`, with `PYTHONDONTWRITEBYTECODE` unset, `python3 scripts/render-cli-reference.py --check` printed `[ok] docs/cli.md is what the generator produces` and left five `.pyc` files, among them `templates/family-root/scripts/__pycache__/bootstrap.cpython-312.pyc` at 11533 bytes (the size the issue reports). The same command on `151a0861` printed the same `[ok]` line and left none (`find . -name '*.pyc'` found 0).

**Mutants.** Each is applied to a copy at the head's test files; "old" is the same mutant under `8062810d`'s own tests.

| Mutant | New tests | Old tests |
|---|---|---|
| M0: drop `PYTHONDONTWRITEBYTECODE` from `child_env()` (the base's behaviour) | `test_child_env_leaves_no_bytecode_in_the_trees_it_runs` fails: `KeyError: 'PYTHONDONTWRITEBYTECODE'` | none to run |
| M1: drop `env=` from `family.py`'s `siblings` child (`scripts/family.py:6543`) | `test_the_tools_that_run_the_projects_validators_give_them_an_environment[scripts/family.py]` fails: ``scripts/family.py:6543 runs the interpreter without `env=inherited_child_environment()` `` | 55 passed (survives) |
| V2: `from repo_shape import shell_line as joined` and a call, in `update-shape.py` | `test_the_tools_that_quote_for_the_host_...` fails: files are `[family, setup-project, shape-doctor, update-shape]` | 3 passed (survives) |
| V3: `family.py`'s `_switch_command` calls `shell_line(..., "posix")` | `test_the_functions_that_quote_for_the_host_...[scripts/family.py]` fails: `_switch_command` missing from the calling functions | 3 passed (survives) |
| V5: a host-quoter call in the suffixless `bootstrap` | the file test fails: `bootstrap` is now among the files | 3 passed (survives) |
| V6 (the exemption): a third function of `scripts/repo_shape.py` calls `shell_line` | the file test fails: `scripts/repo_shape.py` is now among the files | 3 passed (survives) |

Each new failure is one test, and the other tests of the file stay green (`1 failed, 8 passed`; `1 failed, 55 passed`). V2, V3 and V5 are R588's mutants as the issue describes them.

On `151a0861`, one run, `run9.sh` (gh stub first on PATH, `GH_TOKEN` bogus, empty `GH_CONFIG_DIR`):

`tests/test_cli_reference.py tests/test_validator_child_encoding.py tests/test_readme_windows_quoting_sentence.py tests/test_bump_leg_paste_lines.py tests/test_family_siblings_placement.py tests/test_repo_hygiene.py`: **227 passed in 698.59s**.

Per file: `test_cli_reference.py` 23 (one new), `test_validator_child_encoding.py` 56 (one new case, `[scripts/family.py]`), `test_readme_windows_quoting_sentence.py` 9 (6 new: the `scripts/family.py` and `setup-project.py` function pins, the alias, the method name, the exemption, the suffixless file), `test_bump_leg_paste_lines.py` 33, `test_family_siblings_placement.py` and `test_repo_hygiene.py` 106 together.

- **origin/main `35133f29`** (includes #657 as `78fe3fff`, which edits `tests/test_bump_leg_paste_lines.py` at :53, :235-244 and `setup-project.py`): clean. On the predicted merge commit, `test_readme_windows_quoting_sentence.py` and `test_validator_child_encoding.py` pass (65 passed), and so does `test_bump_leg_paste_lines.py` (33 passed). `family_next_command` is still the only function in `setup-project.py` that calls `shell_word`.
- **#630** (`5b140bd3`): conflicts in `docs/handbook.html` only, and it does so against `8062810d` and `35133f29` without this commit, so not this change's. It changes `scripts/render-cli-reference.py`, `docs/cli.md` and `tests/test_repo_hygiene.py`; none of those hunks overlaps mine, and `merge-tree` reports no conflict in them.
- **Lane 4's `family.py` work:** the heads I could fetch are #670 (`pr670`) and #671; `fix/664-surviving-mutants` and `fix/696-setup-family-folder` are on origin too. Clean with each. Lane 4's other `family.py` branches (#684, #686, #688, #689, #693, #674) are not on origin and not in the shared `.git`, so I could not check them. Predicted merges with #670, #671 and lane 5's `fix/646` pass the two guards' files (65 passed each).
- **Other open heads touching a tool the inventory reads:** #703 and `fix/696` (`setup-project.py`), #699 (`adopt-project.py`), #700, #701, #702 and #705 (`shape-doctor.py`), `fix/664`: clean, and the inventory file passes on each predicted merge (9 passed each). #682, #698 and #706: clean.

- **No quoting change.** The Git Bash dialect (option (a)) is a separate v1.1.1 issue; the inventory only holds what the sentence says today.
- **`docs/release-notes/v1.0.0.md:532`** says the `.pyc` is left by `test_cli_reference.py`'s children. That is true of v1.0.0 and I left it. The v1.1.0 notes (#630) may want one line.
- **`--others` in the file listing.** A new, untracked tool is scanned before it is added, as `rglob` did; a tracked file deleted from the work tree is skipped.

- **A quoter handed on as a value is not a call.** `map(shell_quoted, words)` or `functools.partial(shell_line)` is not seen by the inventory (said in `host_calls`' docstring). Nothing does it today.
- **The function pin counts functions, not calls.** A function with two host-dialect calls where only one is switched to POSIX still passes. Today the one-call functions are `_switch_command`, `_print_next`, `_checked_mount_path`.
- **`_print_next_steps` prints a `cd {shell_quoted(work)}` line** the sentence's list (`NEXT`, `switch -c`, `add`, `git rm -r --cached`) does not name. It belongs to the Git Bash dialect issue.
- **The launcher guard's `LAUNCHERS` still has no row for `src/openreposhape/cli.py` (`run_child([sys.executable, ...], env)`) or `setup-project.py` (its own `run` with a `PYTHON` variable).** Both spell the child differently from `subprocess.run([sys.executable, ...])`.

Review: lane 5's independent review approved 151a086 with nits only, and codex reviewed it. CI (Brett Heap's ruling 27 and his fast-refresh ruling of 2026-10-15T22:48:35Z): H0 151a086 passed tests, tests-git-bash and SonarCloud; the head 949fd4d is a clean update-branch merge of main bf1f099, with tests-git-bash and SonarCloud green; and the local gate passed on its predicted squash tree 9cd4767 over main 974d482: the bump_leg_paste_lines, cli_reference, readme_windows_quoting_sentence, validator_child_encoding, adopt_plan_leg_path_help, repo_hygiene, agents_md_codes sets, 290 passed. Landed on Brett Heap's word of 2026-10-17T10:59:39Z, relayed by lane 3 on #473: "merge lane 5's approved v1.1.0 drafts".

Closes #665

…d A3 (three SHOULDs, four nits), and notes entries for the seven pull requests landed since bf1f099, current to main 2000488 (#563, #683)

Round A4, from lane 2's review (#630 issuecomment-6233033833, READY):
- SHOULD 1: the doctor's exit-3 list names "a validator of its own that
  crashed or could not be run", so the case of one that cannot be given
  its `PYTHONPATH` (shape-doctor.py's EXIT CODES, #278) is listed too:
  README.md:1208-1222, its handbook twin (`doctor`) and the notes' docs
  line. The paragraph re-wraps to one more line:
  tests/readme-cap.d/683.txt is +2, and its text now says which causes
  the EXIT CODES block names and that #742 added the partial clone and
  #701 the naming policy. README.md is 1475 lines, its cap (1422 + 2 + 5
  + 12 + 22 + 10 + 2). Both `Keeping a project's shape current` markers
  move to c728c970: `doctor` text and marker, `current` marker only.
- SHOULD 2: #727's entry names the leg description, whose em dash stopped
  every `execute` against GitHub at the first leg.
- SHOULD 3: #749's entry names `source-ambiguous`, for an `org/repo` that
  is also a directory here.
- Nits: the doctor section's three near-duplicate pairs are merged (#636
  with #737, #632 with #700 and #705, #586 with #736); #718 has its own
  bullet; #634's entry names `git_out`'s spelling for every caller and
  #744's the gate's `--link-source-label` and `--link-remedy`; the header
  comment says 2026-10-17 at main 2000488.

… in command scope and in a global config that includes the person's own, so a `copytree` of a fixture no longer meets a detached repack deleting its loose objects (#645) (#713)

**What changed.** One session fixture in `tests/conftest.py`, `no_auto_maintenance` (autouse), and one new test file, `tests/test_no_auto_maintenance.py`. No shipped file and no other test file changes. Four commits: the fix and its tests (e2110f8), a comment (accc7d2), and the fix round below (8cfc8eb, and 979bb39, which only shares a test helper).

The fixture sets `gc.auto=0` and `maintenance.auto=false` for every git the session starts, in two scopes:

- **Command scope** (`GIT_CONFIG_COUNT`), appended after the entries the environment already holds (the Windows job holds two). Every git the suite starts, every git a tool under test starts, and every git a `git submodule` starts inherits it. It outranks every config file.
- **A global config file** (`GIT_CONFIG_GLOBAL`, in the basetemp). It includes the global config git would read without it (the file `GIT_CONFIG_GLOBAL` already named, or `$XDG_CONFIG_HOME/git/config` and then `~/.gitconfig`) and sets the two keys after it. This one is for the `receive-pack` a push starts in a local remote: git starts it with `GIT_CONFIG_COUNT` and `GIT_CONFIG_PARAMETERS` removed, so command scope never reaches it. Where `HOME` is unset the `~/` paths are left out, and an empty `GIT_CONFIG_GLOBAL` includes nothing (fix round, below).

A comment beside #440's note in `clone_just_pushed` says why, names both sites, and says what is left.

**Why.** `shutil.copytree` reads a repository's `objects/` one file at a time. The suite copies a repository a fixture has just committed in, fetched into or pushed to in 139 places. Each `git commit`, `merge` and `fetch`, and the `receive-pack` in a remote after a push, runs `git maintenance run --auto` as it finishes. From git's source:

- git 2.46: the auto run stays in the foreground.
- git 2.47: it is started with `--detach`, takes `objects/maintenance.lock` and then detaches, so the command returns while it runs.
- git 2.52 and 2.53: the default strategy is still `gc`, which does nothing below 6700 loose objects.
- git 2.54: the default strategy is `geometric`. Its repack runs when packs are out of geometric order, or once its estimate, taken from `objects/17` alone, is above 256 loose objects, so two loose objects there are enough (`maintenance.geometric-repack.auto`, 100, rounded up). It deletes the loose objects it packed.

So on a current git, a copy taken just after a commit can find a loose object gone. It happened twice on the Linux runner:

- `holder` (`tests/test_family.py:129`), in `test_family_member_name.py` (lane 1's report on #473);
- `the_standard_moved` (`tests/test_doctor_pin_restore_merges.py:99`), a copy of the session's `standard` with its `.git`, in `test_copies_neither_side_edited_are_taken_whole_with_the_pin` on #623's run 38895011713: `shutil.Error ... standard5/openRepoShape/.git/objects/1e ... [Errno 2]` (lane 2's #473 comment 6215422231). The same function copies `moved` at :102 just after a commit in it.

Both are covered by the same session setting: the commits before each copy run under `os.environ` (`commit_all` passes `{**os.environ, ...}`).

A listing of `.git/objects` taken before and after such a repack also differs: lane 3's `objects changed` in `tests/test_family_bump_remove_rollback.py` (#736's Linux run 38981191418), 37 loose objects packed into two. The same setting covers it (i645 on #645).

**Decisions and evidence.**

- *Option A (the suite's environment), not B or C.*
  - B (config in each copied repository) would have to reach repositories the tools under test create themselves, such as the bare remotes `scaffold-project.py --local-remote-dir` makes and pushes into before a test sees them. A config written after that first push is too late.
  - C (a copy that survives a repack) cannot be made safe. A copy can list `objects/pack/` before the new pack lands, and then a loose-object directory after it was emptied. That copy succeeds and is missing objects.
  - A covers all 139 places from one place.
- *Two scopes, not one.* Probe on git 2.43, pushing into a local bare remote with `receive.denyDeletes=true` given each way:
  - with `GIT_CONFIG_COUNT`, the branch was deleted;
  - with `-c`, deleted;
  - through a `file://` URL with `GIT_CONFIG_COUNT`, deleted;
  - with `GIT_CONFIG_GLOBAL`, `remote: error: denying ref deletion` (refused).

  So command scope alone misses the remotes, and ten copies are of bare remotes. A global file alone would be dropped wherever a test gives git a global file of its own (14 test files set `GIT_CONFIG_GLOBAL`, five more through `excluding()`). No test file replaces both scopes and also copies a repository. rv645, the reviewer, repeated the `receive.denyDeletes` probe and got the same answers, and instrumented the git calls of the batches it finished before the checkpoint: the only receive-packs that ran without both settings were in `test_family_add_excludes.py` and `test_adopt_clone_template.py`, neither of which copies a remote.
- *Which verbs start auto maintenance* (git 2.43 trace2): `commit`, `fetch`, `pull` and `submodule update --remote` (its fetch in the submodule) start `git maintenance run --auto`. A push's `receive-pack` starts `git gc --auto --quiet`. `clone`, `submodule add` and `submodule update --init` start none.
- *Behaviour no test checks is unchanged.* The person's own global config is still read: it is included, and it comes first. A test of that is part of the new file. The tests that read or set a global config (`test_git_helper_identity.py`, `test_adopt_git_reads.py`, `test_tracking_branch_ref.py` and others) set their own, which replaces the session's.

**Fix round (8cfc8eb), on rv645's review** (no MUST; two SHOULD, five NIT).

- **SHOULD 1: with `HOME` unset every git was fatal.** The file's include of `~/.config/git/config` and `~/.gitconfig` made git exit 128, `error: could not expand include path '~/.config/git/config'`, in every command the session started. The estate runs with `HOME` set, so nothing failed here; an `env -i` or hermetic runner would have lost the whole suite.
  - `session_global_config` now writes a `~/` path only where `home_is_known()` (`HOME` is set, or `os.name == "nt"`, where Git for Windows finds a home itself), and writes no `[include]` header when nothing is included. An `XDG_CONFIG_HOME` that is set is still included, because it needs no `HOME`.
  - The two `test_a_persons_own_global_config...` cases skip where `HOME` was unset. They skip on the environment and not on the file's bytes, so a fixture that dropped its includes still fails them (probe M5 below).
  - A new test, `test_where_home_is_unset_the_file_is_one_git_can_read` (with and without `XDG_CONFIG_HOME`), reads the file back through `git config --global --includes`. It is skipped on Windows. It and the empty-value test share one helper, `probe_read_from_the_session_file`, so the new tests do not repeat a body for SonarCloud's duplication gate.
  - Measured under `env -u HOME -u XDG_CONFIG_HOME`, `run9.sh`, git 2.43.0:

    | file | before (accc7d2) | after (8cfc8eb) |
    |---|---|---|
    | `tests/test_clone_just_pushed.py` | 1 passed, 6 errors | 7 passed |
    | `tests/test_no_auto_maintenance.py` | 3 failed, 2 passed, 2 errors (7 tests) | 9 passed, 2 skipped (11 tests) |
    | `tests/test_family_member_name.py` | not run | 13 passed |

    The 2 skips are the two `test_a_persons_own_global_config...` cases.
  - Where `HOME` is set and the file is written as before, nothing changes: across 27 combinations of `HOME` (set, unset, empty), `XDG_CONFIG_HOME` (set, unset, empty) and `GIT_CONFIG_GLOBAL` (unset, a file, empty), the file's bytes are the same as accc7d2's in the 12 where `GIT_CONFIG_GLOBAL` names a file or `HOME` is set with `GIT_CONFIG_GLOBAL` unset, and differ in the 15 where `HOME` is not set or `GIT_CONFIG_GLOBAL` is empty.
- **SHOULD 2: nothing guarded the fixture's scope.** At function scope all seven tests passed (rv645's probe), and the session fixtures `scaffolded` and `family` would have been built before the setting existed. A new test, `test_the_settings_are_in_place_before_a_session_fixture_builds_a_repo`, takes a session fixture as its FIRST argument, which reads `GIT_CONFIG_GLOBAL` and `GIT_CONFIG_COUNT` as that fixture sees them, and compares them with what the test sees and with the fixture's file. Pytest builds the higher scope first, and then an autouse fixture, so the fixture is only in place early enough if it is session scope and autouse.
- **NIT 1: the receive-pack test failed under a person's global `core.hooksPath`**, which hid the remote's own `post-receive` hook (`FileNotFoundError` on `read-by-receive-pack`). The test now sets `core.hooksPath` to the remote's own `hooks` directory in the remote's local config, which outranks a global one. Measured with `GIT_CONFIG_GLOBAL` naming a file that holds `core.hooksPath`: before, `1 failed, 4 passed, 2 skipped`; after, `9 passed, 2 skipped` (11 tests).
- **NIT 2: an empty `GIT_CONFIG_GLOBAL=` was read as unset.** Git 2.43 reads it as "no global config" (checked here: with `HOME` holding a `.gitconfig` probe, `GIT_CONFIG_GLOBAL=` does not read it). The fixture now includes nothing for an empty value: `if named is not None: included = [...] if named else []`. A new test, `test_an_empty_GIT_CONFIG_GLOBAL_is_no_global_config_and_includes_nothing`, fails on the old `if named:`.
- **NITs 3 to 5: no code change.**
  - NIT 3: `test_family_dry_run.py`'s own `NO_MAINTENANCE` is redundant now. It lives in another test file that this PR leaves alone, and it is harmless.
  - NIT 4: a `git config --global` read without `--includes` sees only the session's two keys. The only reader is `setup-project.py:1105`, behind `os.name == "nt"`, and no test reads it. `_credential_helper_configured` uses `--get-all` with no scope, so it still sees the person's config. The conftest comment already says so.
  - NIT 5: the version facts in the conftest comment ("2.47 detaches", "2.54 default geometric") are from git's source tags and are not run here: only git 2.43.0 is installed. The comment is unchanged.

**Tests** (`run9.sh`: gh stub first on PATH, identity blanked; git 2.43.0, Python 3.12, pytest 9.1.1).

- On the fix round (8cfc8eb; 979bb39 differs from it in the new test file alone, and the batches that read that file were run on it):
  - `tests/test_no_auto_maintenance.py`: 11 passed (7 from the first commit, 4 new: the `HOME` test twice, the empty value, the scope).
  - `tests/test_no_auto_maintenance.py`, `tests/test_clone_just_pushed.py`, `tests/test_repo_hygiene.py` and `tests/test_git_helper_identity.py` together, on 979bb39: 105 passed. With `tests/test_family_dry_run.py` added, on 8cfc8eb: 166 passed.
  - `tests/test_adopt_git_reads.py`, `tests/test_tracking_branch_ref.py`, `tests/test_adopt_late_failure.py`, `tests/test_adopt_github_exits.py` and `tests/test_family_add_excludes.py` (the tests that read or set a global config or a hooks path): 314 passed.
- On the first two commits (e2110f8 for the first four, accc7d2 for the rest; the second commit changes comment lines only). The fix round changes nothing where `HOME` is set and `GIT_CONFIG_GLOBAL` is not empty (the byte comparison above), so these were not run again:
  - Family, `tests/test_family*.py` (20 files): 823 passed, 19 skipped.
  - Adopt, `tests/test_adopt*.py` (46 files): 3463 passed, 2 skipped.
  - Doctor, `tests/test_shape_doctor.py` and `tests/test_doctor*.py` (12 files): 741 passed, 3 skipped.
  - Scaffold, `tests/test_scaffold*.py`: 634 passed.
  - Update-shape and bump-leg, `tests/test_update_shape*.py` and `tests/test_bump_leg*.py` (24 files): 857 passed, 4 skipped.
  - The rest of the files that copy a repository (`test_bootstrap_after_bump.py`, `test_non_list_project_fields.py`, `test_pin_source_env_collisions.py`, `test_pin_source_unreadable.py`, `test_shape_pin_files_not_a_list.py`, `test_validator_child_encoding.py`, `test_siblings_family_name.py`, `test_bootstrap_spelling.py`, `test_non_utf8_git_reads.py`), with `test_repo_hygiene.py`, `test_git_helper_identity.py`, `test_clone_just_pushed.py` and the new file: 924 passed.
  - On a merge of accc7d2 with main c6122e8: `test_no_auto_maintenance.py`, `test_git_helper_identity.py`, `test_repo_hygiene.py`, `test_clone_just_pushed.py` and `test_family_member_name.py`, 114 passed.

**Reproductions.**

- *The mechanism, on git 2.43.* A repository of 300 files plus two loose objects named `17…`, committed under `gc.auto=1`, then copied at once with `shutil.copytree`. This is what git 2.54 does to such a repository by default. With the base's settings, 10 of 10 copies failed, then 9 of 10 (`[Errno 2]` on a loose object directory or file). With the fix's two entries appended after it, 0 of 10 failed.
- *The emulation of the race* (rv645's recipe, run on 8cfc8eb: a global `gc.auto=1` that includes the person's `~/.gitconfig`, plus a `core.hooksPath` pre-commit hook that leaves two `17…` objects and drops `gc.log`, so git 2.43 repacks in the background after each commit; `GIT_TRACE2_EVENT` over the whole run). Base figures are rv645's, on a524542; head figures are the fix round's own, on 8cfc8eb:

  | file | git | auto-maintenance children | repack runs | result |
  |---|---|---|---|---|
  | `test_doctor_pin_restore_merges.py` | base | 78 `maintenance run --auto`, 77 `gc --auto` | 65 | 1 failed, 14 passed, 1 error |
  | | head | 4 `gc --auto` (from `receive-pack`, inert under `gc.auto=0`) | 0 | 16 passed |
  | `test_family_member_name.py` | base | 19 `maintenance run --auto`, 29 `gc --auto` | 15 | 13 passed |
  | | head | 14 `gc --auto` (inert) | 0 | 13 passed |

  On the base, rv645 reproduced the symptom itself: `shutil.Error ... moved/openRepoShape/.git/objects/pack/tmp_rev_...`, at `the_standard_moved`'s copy of `moved` (`tests/test_doctor_pin_restore_merges.py:102`). On head, 0 maintenance runs and 0 repacks in both files.
- *The first writer's runs on the issue's file* (`test_family_member_name.py`, base then head, 19 maintenance and 15 repacks against 0 and 0) agree.

**Mutation probes.** Each reverts one hunk of the fix in a throwaway clone; the new file then fails. First round (against the first seven tests):

| probe | fails |
|---|---|
| fixture sets nothing | 6 of 7 (all but the append test) |
| no command scope | `test_a_commit_a_fetch_and_a_merge_start_no_maintenance[a-tests-own-global]` |
| no global file | the receive-pack test, both person's-config cases |
| count overwritten, not appended | the append test |
| global file without the includes | both person's-config cases |
| the two keys before the includes | both person's-config cases |
| no `maintenance.auto` | 5 tests |
| no `gc.auto` | the receive-pack test, the append test |

Fix round (against the eleven tests):

| probe | result | what fails |
|---|---|---|
| S1, `no_auto_maintenance` at function scope | 1 failed, 10 passed | the scope test, alone (the first seven passed in rv645's run of the same mutant) |
| S2, not autouse | 4 failed, 7 passed | the two commit/fetch/merge cases, the tool test, the receive-pack test |
| H1, `home_is_known()` always true | 2 failed | `test_where_home_is_unset_the_file_is_one_git_can_read`, both variants |
| H2, the XDG include needs `HOME` | 1 failed | the same test, the `xdg` variant |
| E1, an empty value is read as unset (`if named:`) | 1 failed | the empty-value test |
| M5, the file includes nothing (the first round's probe, again) | 3 failed, 8 passed | both `test_a_persons_own_global_config...` cases, and the `xdg` variant of the `HOME` test |
| K1, the receive-pack test without its own `core.hooksPath`, under a global `core.hooksPath` | 1 failed, 8 passed, 2 skipped | the receive-pack test |

S2 is caught by tests that ask for the setting by itself; the scope test does not catch it, because earlier tests in the file build the fixture on request. K1 only fails where a global `core.hooksPath` is set, as NIT 1 says.

On the base itself the new file does not import (`cannot import name 'NO_AUTO_MAINTENANCE'`).

**Merge checks** (`git merge-tree --write-tree` on 979bb39): clean against origin/main 2fac979 and against lane 5's `fix/662-insteadof-helper` (4149cbb; #662 is stacked on accc7d2 and also edits `tests/conftest.py`: the fix round's hunks are in `session_global_config`, its helper `home_is_known`, and the comment above them). Earlier, on e2110f8 and accc7d2: clean against origin/main d4a7fab and c6122e8, #621, #622, #630, #631, #634, #635, #636, #637, #638 and #639, and the sibling branches for #646, #647, #648 and #649.

**What it leaves.**

- A git whose environment drops both scopes (a `GIT_CONFIG_COUNT` overwritten, not appended to, together with a test's own `GIT_CONFIG_GLOBAL`, or an environment built from nothing), and a push made under a test's own global file. No repository the suite copies is made or pushed to that way today.
- A git older than 2.32 ignores `GIT_CONFIG_GLOBAL`. Its `receive-pack` runs `gc --auto`, which does not detach below 6700 loose objects.
- `clone_just_pushed` keeps reading through git. A test with its own global file still needs it.
- `test_family_dry_run.py`'s own `NO_MAINTENANCE` is now redundant, and is left alone (NIT 3).
- Not run: a real Windows job (none runs the full suite since #597, and the `HOME` test is skipped on Windows), and a git newer than 2.43.

**Copies found** (`git grep -n 'shutil.copytree(' -- tests`, 152 calls):

- 127 copy a repository the suite built (non-bare, many holding `.git/modules`): `conftest.py` 1, `test_family.py` 18, `test_shape_doctor.py` 32, `test_doctor_legs_members_next.py` 8, the `test_update_shape*` files 30, and 38 more in 28 files. Four of them copy a subtree that holds no store: `standard / name` twice, and a member's work tree twice.
- 10 copy a bare remote, or a folder of them: `test_bump_leg_paste_lines.py:95`, `test_doctor_unfinished_merge.py:166`, `test_family_add_member_id.py:239`, `test_family_add_refusals.py:487`, `:788` and `:1983`, `test_family_dry_run.py:1446`, `test_family_tracking_branch.py:279`, `test_update_shape_landing.py:156` and `test_update_shape_next_quoting.py:116`.
- 2 copy a `.git` directory: `test_adopt_clone_template.py:190` and `test_scaffold_mount_ignored.py:381`.
- 13 hold no repository: a template, or this checkout with `.git` ignored.
- `test_adopt_plan.py:449` copies a clone named by `SHAPE_MEDXEHR_CLONE`. It is outside the suite and skipped without the variable.

No shipped script copies a repository.

**Checklist candidates** (rv645's; the coordinator places them):

- The import-time git probe at `tests/test_family_refuse_up_front.py:75-96` runs in a throwaway directory before any session setting. It is harmless today.
- Tests that overwrite `GIT_CONFIG_COUNT` (14 files) lose command scope and rely on the global file alone. That holds today, and nothing guards it.

Review: rv645, lane 5's independent review, found no MUST, two SHOULDs and five NITs on accc7d2; the fix rounds above take them, and its re-verification approved 979bb39. CI (Brett Heap's ruling 27): H0 979bb39 passed tests, tests-git-bash and SonarCloud; the head a9f36ce is a clean update-branch merge of main bf1f099, with tests, tests-git-bash and SonarCloud green; and the local gate passed on its predicted squash tree 760892f over main 2000488: every test file that #706, #703 and lane 5's six round-1 PRs change, run under #713's conftest, with the two copytree-race files and the hygiene trio, 1332 passed, 3 skipped, 1 xfailed. Landed on Brett Heap's word of 2026-10-17T10:59:39Z, relayed by lane 3 on #473: "merge lane 5's approved v1.1.0 drafts".

Closes #645
