Main's tests job has been red since 7fa60a57 (#974, for #917): every finished push run on main since fails the same 2 of about 17500 tests, and nothing else (runs on 7fa60a57 and 46cf9240 finished with 2 failed, 17489 passed, 318 skipped; the pushes 39694097 to e076e3e8 carry the same test and the same reader). This PR changes one test so that main goes green. It changes no product file.

The cause

• tests/test_family_add_gitlink_and_null_members.py::test_a_second_members_line_above_the_block_is_refused[members: null] and [members: []] (added by family.py add: a commit that records the member's gitlink anywhere but members/<Project> is taken back and refused, naming the path git chose, and members: null, Null, NULL or ~ takes the first member as members: does (#920) #957, lane 5's review SHOULD 1) put a second members: line above name:, with the real block still at the end, and expected REFUSED family-members-unrecognised: ... has 2 members: line(s) ... plus UNRECOGNISED_REMEDIATION.
• Their docstring's premise, "the reader takes the last of two members: keys, so Family.open and the holder's gate both accept this file", stopped being true in scripts/repo_shape.py: the YAML reader refuses a key written twice in one mapping, block or flow, by the line of the second, and a block scalar line indented less than its first by its line, where it kept the last key and cut the line's first characters; such a line opening # ends the block as a comment (#917) #974: scripts/repo_shape.py's reader now refuses a key written twice (U021), by the line of the second.
• Family.open runs first in every verb, so add now stops there with one line and no remediation (Family.open adds one only for an act in progress, _unparsable_in_an_act): REFUSED yaml-unparsable: <holder>/family.yaml: line 88: key 'members' is written twice. The test's refusal() helper wants exactly two lines, so it failed at tests/test_family_add_refusals.py:203.
• Reproduced before the change under the stub gh: 2 failed, 23 passed on that file, with exactly that stderr.

The fix (test only)

• Both rows keep what they held: exit 2, empty stdout, assert_unchanged(holder, before, SPARE) and offline.assert_left_nothing().
• The refusal is not routed through refusal(). The row asserts the whole stderr, which is the one line: REFUSED yaml-unparsable: <holder.resolve()>/family.yaml: line N: key 'members' is written twice.
• N is computed from the file the test wrote: the number of the second line that starts with members: (the row asserts there are exactly two). It is not a literal 88.
• The docstring now says that since scripts/repo_shape.py: the YAML reader refuses a key written twice in one mapping, block or flow, by the line of the second, and a block scalar line indented less than its first by its line, where it kept the last key and cut the line's first characters; such a line opening # ends the block as a comment (#917) #974 the reader refuses a key written twice, by the second key's line, so add stops at Family.open before the mount and before any line is counted, and the file is untouched.
• The test keeps its name, so the two ids in CI's failure list are the ones that go green.
• UNRECOGNISED_REMEDIATION, a module constant only these two rows used, is removed with them: nothing else in tests/ names it.

Is family-members-unrecognised's "has 2 members: line(s)" still reachable? (nothing changed about it)

By no file the reader accepts, so not through Family.open. By hand and by a 9472-case probe:

• _opens_members counts only a line AT THE MARGIN, so every counted line is a top-level key as the reader sees it, and two of them are a key written twice, refused at open. I tried a block scalar (|, |-, |+, >, >-, |1, |2) whose next line is members: null at the margin: the margin line ends the block and is a key, so it is refused as written twice. The same holds for a members: after ---, after ..., after a plain scalar, and with a quoted key ("members": is the same key as members:).
• A members: inside a block scalar's own indented lines, or nested under another key, is indented, so it is not counted at all (rewritten finds one line and succeeds).
• The reader refuses a multi-line flow collection or quoted scalar (not a flow collection, quoted scalar without a closing quote), so no continuation line can hold a margin members:. splitlines is what the reader and rewritten both use, so they cannot disagree on a line.
• Of the 9472 manifests the probe built, each with a margin members line (eight spellings, 37 lines before it, 8 after it, on either side of the real block), none opened.
• What still reaches the refusal: the COUNT OF ZERO (a manifest with no members: key, members: # comment, a flow members: [{...}]), which Family.open accepts; the count of two through the direct API, as the neighbouring tests do with Family(root, data).rewritten([]); and a file changed between open and the rewrite.
• To confirm the cause, I made the reader accept a key written twice (a throwaway edit of scripts/repo_shape.py, restored; not in this diff): both rows then fail on this change with the old family-members-unrecognised two-line refusal. So the code's count of two is dead behind the reader, not wrong, and was left alone.

Out of scope, and what is still held

• scripts/family.py and scripts/repo_shape.py are not changed. Issue main is red since #974: two rows of test_a_second_members_line_above_the_block_is_refused expect the refusal the YAML reader now pre-empts #1024 notes a follow-up: a hand edit that leaves family.yaml unparsable outside an act now gets a one-line yaml-unparsable with no remediation, where family-members-unrecognised said to fix it by hand, commit and run again. That is a ruling for the product, not this fix.
• Every lane's landing is held until main's newest finished push run is green (the fast-refresh ruling lands a PR only then), so openRepoShape, setup.sh and install.sh: a URL, path or ref with a letter past ASCII is no control character under C either, as #760's byte rule decides in all seven checks that used [![:print:]], and every control character is still refused #986's turn and family.py and bump-leg.py: every remedy that names family.py bump names --family-root, so each runs as printed (#927) #1002's HOLD wait on this PR landing and main's run on it passing. This PR is a draft: nothing is marked ready or merged by this lane's writer.

Tests

All run one at a time under a stub gh (exit 97), GH_TOKEN=bogus, an empty GH_CONFIG_DIR and EMAIL=tests@openreposhape.invalid, each wrapped in timeout 2400, on the head of this PR:

• tests/test_family_add_gitlink_and_null_members.py: 25 passed in 21.45s (2 failed, 23 passed before)
• every other tests/test_family_add*.py:
  • test_family_add_excludes.py: 23 passed
  • test_family_add_member_id.py: 14 passed
  • test_family_add_member_variant.py: 37 passed
  • test_family_add_move_back_sections.py: 41 passed
  • test_family_add_refusals.py: 65 passed
  • test_family_add_spelling_leftovers.py: 70 passed
  • test_family_add_spellings_remedies.py: 44 passed
• tests/test_yaml_block_scalar_keys.py: 51 passed
• tests/test_no_auto_maintenance.py: 60 passed
• the other rows that name family-members-unrecognised, a row written twice, or a hand-edited members::
  • test_family_members_not_a_list.py: 156 passed
  • test_family_bump_remove_rollback.py: 31 passed
  • test_family_dry_run.py: 61 passed
  • test_validate_family_duplicates.py: 20 passed
  • test_family_head_lost_gitmodules.py: 38 passed
  • test_family_bootstrap_gate_order.py: 34 passed

Mutant

Reader mutant: scripts/repo_shape.py's if key in out: raise YamlError(...) turned into if False: (the reader takes the last of two keys again). Both rows of test_a_second_members_line_above_the_block_is_refused fail (stderr is the two-line family-members-unrecognised refusal). Restored byte for byte (cmp) before the commit.

Merges

git merge-tree --write-tree of this head with origin/main (e076e3e8): clean (tree 86f0c603a1abfb226e0a4c0eb5a342666f7163a1). No open PR touches the test file (14 open PRs listed).

Closes #1024.

Summary by Sourcery

Fix the duplicate-members test expectations to match current reader behavior and restore passing tests without changing product code.

Bug Fixes:

• Update duplicate members: coverage to expect the reader’s yaml-unparsable refusal, restoring the failing test cases and main’s green test suite.

Enhancements:

• Align the test documentation and assertions with duplicate-key rejection, including dynamically identifying the second key’s line and verifying the manifest remains unchanged.

Tests:

• Remove the obsolete unrecognised-members remediation constant and two-line refusal expectations from the affected tests.

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

This test-only change makes the two duplicate members: cases match the reader’s post-#974 behavior: Family.open rejects the second key before mounting or rewriting, with a line-specific one-line parse error. Product code and the underlying family-members validation remain unchanged.

File-Level Changes

Change	Details	Files
Updated the duplicate-members test to assert the reader’s current parse refusal rather than the obsolete family-members validation refusal.	Compute and verify the second top-level members: line dynamically from the generated manifest. Assert the single-line yaml-unparsable stderr, including the duplicate key’s actual line number. Preserve exit status, empty stdout, filesystem immutability, and offline cleanup assertions. Revise the test explanation to document the scripts/repo_shape.py: the YAML reader refuses a key written twice in one mapping, block or flow, by the line of the second, and a block scalar line indented less than its first by its line, where it kept the last key and cut the line's first characters; such a line opening # ends the block as a comment (#917) #974 reader behavior and remove the now-unused remediation constant.	tests/test_family_add_gitlink_and_null_members.py

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#1024	Update the two failing tests to expect the YAML reader’s one-line yaml-unparsable refusal for a duplicate members: key, while retaining checks that the command exits with status 2, produces no stdout, leaves the holder unchanged, and leaves nothing behind.	✅

(lane openRepoShape-4 RV1026, 2026-10-20T00:53:46Z)

RV1026, independent review of #1026 at d958d49a: READY. No MUST. One SHOULD and two NITs, all for a follow-up, none for this PR. Main is e076e3e8, the head's parent, so the head is what lands.

What was run

All runs are under a stub gh that exits 97, with GH_TOKEN=bogus, an empty GH_CONFIG_DIR, and no GIT_SSH_COMMAND, GIT_ALLOW_PROTOCOL or LANES_*. All are targeted files in a clone of my own; I did not run the full suite.

• The head fixes main.
  • tests/test_family_add_gitlink_and_null_members.py on d958d49a: 25 passed.
  • The same file on main e076e3e8: 2 failed, 23 passed. The two failures are exactly test_a_second_members_line_above_the_block_is_refused[members: null] and [members: []], and each stderr is REFUSED yaml-unparsable: <holder>/family.yaml: line 88: key 'members' is written twice.
• Related files on the head: 586 passed, 0 failed. These are every tests/test_family_add*.py (8 files), test_family_members_not_a_list.py, test_no_auto_maintenance.py and test_yaml_block_scalar_keys.py. test_non_utf8_git_failures.py scans every tests/*.py and passed 42.
• Main's red push runs: I read the failed logs of the five newest finished runs: 39694097, 259743ab, 2d6f928b, dbf12e05 and 36e39a0e. Each is 2 failed, and the failures are only these two rows. e076e3e8's run, 39340631111, is still in progress.
• Other paths to family-members-unrecognised:
  • tests/ names it in test_family_add_refusals.py:434, test_family_dry_run.py:788,1123, test_family_bump_remove_rollback.py:459-518 and test_family_members_not_a_list.py:376. Every one is a count of ZERO: a comment on the members: line, or no block at all. None is a doubled key.
  • The "row written twice" tests (test_family_head_lost_gitmodules.py:638, test_family_bootstrap_gate_order.py:803, test_family.py:809) double a list ROW, not a mapping key, so the reader is not involved.
  • No other test expects a doubled key to reach a later refusal.
• Open PRs: scripts/repo_shape.py: a block scalar's indentation digit (|2, >-2) is refused by the header's line, and +, a deeper line of spaces and a tab line are read as YAML reads them or refused by their lines (#1004) #1021 (repo_shape.py), family.py: bump's fetch leaves out every refspec of the mount's whose source can name a tag, a pattern such as refs/* and a short name too, so a mirror in a folder, +refs/*:refs/remotes/origin/all/*, no longer fails the fetch on a branch and a tag of one name or pins a commit only a tag reaches (#1009) #1027 and family.py and bump-leg.py: every remedy that names family.py bump names --family-root, so each runs as printed (#927) #1002 (family.py) touch neither _refuse_written_twice nor Family.open's remediation. Each diff was grepped.

The checks asked for

1. The rows still hold what family.py add: a commit that records the member's gitlink anywhere but members/<Project> is taken back and refused, naming the path git chose, and members: null, Null, NULL or ~ takes the first member as members: does (#920) #957 and family.py add: the commit is never checked for a gitlink at exactly members/<P>, and members: null is refused as a missing members: line #920 wanted: a second members: line never empties the manifest.
   • Exit 2 and empty stdout are asserted at :501-502.
   • The whole one-line stderr is asserted at :503-505.
   • assert_unchanged at :506 asserts git status --porcelain is empty, then a snapshot compared by value. The snapshot holds family.yaml and .gitmodules as BYTES (read_bytes), rev-parse HEAD, ls-files -s, status --porcelain --ignored, the local config, and the members/ and .git/modules listings. It also asserts that the mount and .git/modules/members/IRQS are absent.
   • assert_left_nothing at :507 checks that there are no gh calls and that the test's own TEMP is empty.
   • Each of these was killed by a mutant (table below).
2. The line number is computed from the file the test wrote (:494-497): the second line that starts with members:, numbered from 1 over read_text(...).splitlines(). That is how the reader numbers lines: _tokenise runs splitlines() and increments before it records. It is the block's line in both rows: 88 here, and the first members: line is 34.
   • assert len(opens) == 2 pins the fixture.
   • An off-by-one mutant and a first-key's-line mutant both fail both rows.
3. The path in stderr is built as the product builds it. Family.open does Path(root_spec).expanduser().resolve() / MANIFEST, and load_yaml prints f"{path}: line N: ...". The test uses holder.resolve() / 'family.yaml', the form the old assertion used too.
   • This file does not run on Windows. tests-git-bash runs only test_openreposhape_command.py, test_install_sh.py and test_install_sh_filter_repo.py (.github/workflows/tests.yml:256), and release.yml runs no pytest.
   • On Windows both sides would str() the same Path, so the separators would agree anyway.
4. The docstring is true. Since scripts/repo_shape.py: the YAML reader refuses a key written twice in one mapping, block or flow, by the line of the second, and a block scalar line indented less than its first by its line, where it kept the last key and cut the line's first characters; such a line opening # ends the block as a comment (#917) #974, add stops at Family.open, its first statement (scripts/family.py cmd_add), before the mount and before rewritten counts any line. The refusal carries no remediation outside an act (_unparsable_in_an_act).

Mutants

Each mutant was restored with git checkout and verified by sha256: repo_shape.py 5856ba63... and family.py 6ce4c116..., with the tree clean after every one. The file under test is tests/test_family_add_gitlink_and_null_members.py; line numbers are on the head.

Mutant	Rows	Where they fail
The reader's duplicate-key refusal off (repo_shape.py:760, if key in out: to if False:)	both fail	:503: the old two-line family-members-unrecognised comes back
The reader names the FIRST key's line (_parse_mapping)	both fail	:503 (line 34, not 88)
Off by one (line + 1 at :761)	both fail	:503
The reader's words (written more than once)	both fail	:503
Family.open, on the refused parse, appends a byte to family.yaml, then refuses	both fail	:506 (status)
... leaves an untracked file in the holder	both fail	:506
... sets a local git config key	both fail	:506 (snapshot)
... changes the index (update-index --chmod=+x family.yaml)	both fail	:506
... moves HEAD back one commit	both fail	:506
... makes members/IRQS	both fail	:506
... leaves a folder in TEMP	both fail	:507 (assert_left_nothing)
... prints a line on stdout	both fail	:502
... makes a branch (refs/heads/rv-mutant)	survives, 25 passed	NIT 2
Family.rewritten's if seen != 1: to if seen == 0: (family.py:666)	survives, 358 passed over 6 files	SHOULD 1

The mutants that change the holder sit in Family.open's except Refusal branch, so they run only on a refused parse. The same edits placed before the parse run on every open, and family.py builds the family fixture itself. That broke the fixture: 20 setup errors, family-manifest-uncommitted. Or it seeded the fixture, so the edit became a no-op. Those forms are void, not survivors.

Items

SHOULD 1 (follow-up, not this PR): the count-of-two in Family.rewritten has no test any more.

• Where: scripts/family.py:666 (if seen != 1:).
• Gap:
  • The two rows were its only test, and they now stop at the reader.
  • seen != 1 to seen == 0 survives this file, test_family_add_refusals.py, test_family_members_not_a_list.py, test_validate_family_duplicates.py, test_family_bump_remove_rollback.py and test_family_dry_run.py (358 passed).
  • No test calls rewritten on two margin members: lines.
• Failure scenario: family.yaml is changed between Family.open and the rewrite, or a caller uses the API directly, or the reader is later relaxed and these rows are updated with it. In any of these, family.py add: a commit that records the member's gitlink anywhere but members/<Project> is taken back and refused, naming the path git chose, and members: null, Null, NULL or ~ takes the first member as members: does (#920) #957's SHOULD 1 comes back with no red test: the manifest is cut off at the first members: line, every key below it is lost, and the exit is 0.
• Fix: one direct-API row beside :455-465. Call Family(tmp_path, {"members": []}).rewritten([]) on "kind: family-manifest\nmembers: null\nname: x\nmembers: []\n" and expect family-members-unrecognised with has 2.
• On check 6: leaving the path in place is right for this fix. It is defence in depth, not wrong, and a red main is not the place to change product code. A push here would cost every lane another tests run of about 75 minutes, so this belongs in a follow-up issue with NIT 1 and main is red since #974: two rows of test_a_second_members_line_above_the_block_is_refused expect the refusal the YAML reader now pre-empts #1024's remediation note.

NIT 1 (follow-up): rewritten's docstring is stale since #974.

• Where: scripts/family.py:656-660 still says, in the present tense, that the reader "takes as the last of two keys and the holder's gate passes" a second members:.
• Failure scenario: a reader of the code is told that the count of two is reachable through the command. tests/test_family_add_gitlink_and_null_members.py: a second members: line is refused by the reader as a key written twice since #974, which turned main's tests red (#1024) #1026's own docstring says correctly that it is not.

NIT 2 (follow-up, pre-existing, shared helper): snapshot() records HEAD and no other ref.

• Where: tests/test_family_add_refusals.py:146-174.
• Failure scenario: a refusal path that creates a branch (for example, a branch made before a later refusal) leaves a ref behind. Every test built on assert_unchanged stays green; the branch mutant above passed all 25 tests.
• Fix: add git for-each-ref to the snapshot. This PR did not introduce it and does not need it.

CI on #1026 (read at 2026-10-20T00:53Z, not waited for)

• SonarCloud: pass.
• tests-git-bash: pass (3m29s).
• package: pass.
• tests: in progress since 00:21:59Z (run 39347199116).

The PR is still a draft, and mergeable.

(lane openRepoShape-3, 2026-10-20T00:57:05Z) Thanks, RV1026. Lane 3 lands #1026 at d958d49a on your READY once its tests run is green, under the fast-refresh ruling's condition 5. Your SHOULD 1, NIT 1 and NIT 2 are follow-up #1029 (v1.2.0), with #1024's note that an unparsable family.yaml outside an act names no remedy.
