Lane: openreposhape-5 (openRepoShape-5)
Claim: #759 (comment)

Based on main. #724 landed as 20004887; this branch holds it and was restacked onto main as 84ce67c9.

Head 08a6ed39. The branch holds #759's commit 052410b6, two merges that took #724's final head and main, and one fix round (08a6ed39, lane 2's rv808). Tests only: tests/test_readme_windows_quoting_sentence.py and tests/test_validator_child_encoding.py. No shipped file changes, and no pinned copy. README, the handbook, AGENTS.md and docs/cli.md are untouched, and render-cli-reference.py --check passes.

Fix round: lane 2's rv808 (2026-10-17), 08a6ed39 on 84ce67c9

One commit, tests only: tests/test_validator_child_encoding.py and tests/test_readme_windows_quoting_sentence.py. No shipped file changes, so no pinned copy, README, handbook, AGENTS.md or docs/cli.md text moves. Pushed to fix/759-quoting-launcher-guards as a fast-forward of 84ce67c9, the coordinator's restack onto main (which answers MUST 1, the conflict with main). Nothing was merged, rebased or amended.

SHOULD 1: the setup-project.py row now flips on the fix it names, and the finding says six children

What failed, measured. On 84ce67c9, with the real setup-project.py changed in a scratch clone, one change per row. The row is test_the_tools_that_run_the_projects_validators_give_them_an_environment[setup-project.py]: xfailed means it is still red, FAILED (XPASS strict) means it says the finding is fixed. Log: v116/f808/toolmut/.

change to setup-project.py	84ce67c9's guard	the new guard
none (control)	xfailed	xfailed
env=child_environment() in run's own subprocess.run, which reaches all six children	xfailed: no signal, and NOT_YET's reason stays false	FAILED (XPASS strict): the row comes out
an env parameter on run, passed at all six calls	FAILED (XPASS strict)	FAILED (XPASS strict)
the same, but the call in why_the_plan_did_not_go_through left out	FAILED (XPASS strict), with a child still bare	xfailed
env= at the five calls the old guard read, no parameter	FAILED (XPASS strict), with a child still bare	xfailed
env= at four of the calls	xfailed	xfailed
a seventh bare child added	xfailed	xfailed, and test_setup_project_starts_six_children_and_the_guard_reads_each fails

Lane 2's two mutants are the bold rows. The first is (a): the guard read the call sites and never run. The second is (b): there are six Python children, not five. why_the_plan_did_not_go_through runs the plan again, again = run(plan, cwd=shape_root, capture=True), and plan is a parameter, so the old argv_of could not read the list.

The sixth child, measured. I called the real why_the_plan_did_not_go_through with a plan that prints a project ... line holding an ellipsis and exits 2, under three encodings (v116/f808/probe6.txt):

PYTHONIOENCODING	what the second run's captured stdout holds	the words returned
utf-8:strict	project Sample and U+2026	the plan was refused (see above).
cp1252:strict	project Sample and U+FFFD	the same
cp1252:surrogateescape	project Sample and U+FFFD	the same

So the first five children write into the stream this process reconfigured to UTF-8, which is the two-encodings finding above. The sixth is captured and read as UTF-8 whatever it wrote: a cp1252 byte becomes U+FFFD. Nothing shows today, because the only test on those lines is startswith(PLAN_STARTS) and that prefix is ASCII. It is the same defect class, and the fix has to reach it too.

The fix (tests/test_validator_child_encoding.py):

• interpreter_runs reads a list a caller hands a function as a parameter, one level up, and a name bound in each branch of an if. A starter's own parameter is left to its callers, which are the runs, so run's own subprocess.run is not counted as a seventh. On the shipped files this changes exactly two reads (v116/f808/probe/survey.py): setup-project.py gains the sixth child (:2312 on 84ce67c9), and scripts/render-cli-reference.py gains :403 (NIT 1).
• environment_of reads, where a call hands no env=, the env= of the function it calls when this module defines that function (run). A name is read as the LAST thing its function bound it to above the call.
• NOT_YET names the six children, says five write into the reconfigured stdout and the sixth is captured, and names both fixes the row reads: an env= in run's own subprocess.run, or an env parameter that all six calls pass.
• test_the_row_flips_on_the_change_the_finding_names runs seven changes to a model of setup-project.py (the table's rows, on a source string). test_setup_project_starts_six_children_and_the_guard_reads_each pins the six functions of the real file: check_names, clone_and_bootstrap, plan_and_confirm, scaffold, self_bootstrap and why_the_plan_did_not_go_through. While the row is an xfail, a seventh bare child changes nothing in it, so the count is what would show it.

NITs 1 to 6: which are taken, which stay

NIT	outcome
1 argv_of read only the first list	Taken. Any list the name is bound to above the call counts; the first-or-last choice is gone. SPELLINGS has the name bound to two lists in each order (the render-cli-reference.py shape), and NOT_RUNS has a name bound to the interpreter only after the call.
2 three host_values behaviours without a case	Taken. VALUE_USES gains self.quote = shell_line, a = b = shell_quoted and a name read in an annotation; the value use in a method sits beside test_a_method_is_named_with_its_class.
3 environment_of joined every binding	Taken. The last binding above the call is read, with cases for a later rebinding, a rebinding after a branch, and one after the call.
4 spellings the launcher guard does not read	Taken in part. interpreter_runs' docstring lists them, as #821's guard lists "WHAT IT DOES NOT SEE", and SPELLINGS gains subprocess.call, check_call and check_output. Stays unread: a tuple argv, [sys.executable, ...] + rest, a function-local exe = sys.executable, import subprocess as sp and from subprocess import Popen, os.exec*. None is in shipped code, and each needs a resolver of its own.
5 aliases counted at the alias	Taken in part. alias_of follows q: object = shell_quoted as it follows q = shell_quoted, so q(x) + q(y) counts 2 and one switched to 'posix' counts 1. names_posix reads a 'posix' argument only after the value the quoter would quote, so functools.partial(quote_arg, 'posix'), which binds the value, is a host use. Stays unfollowed: an alias made by a tuple, a chained assignment, a walrus or a conditional. host_calls' docstring says so, and NOT_FOLLOWED pins what is counted instead (the statement, once for each quoter it names). None is in shipped code.
6 #821's calls_to reads host_call only	Not changed here, and not #821. See below.

NIT 6, for whichever of #808 and #821 lands second. #821's calls_to counts host_call's calls and not host_values' uses, so on the merge skips_the_question does not see a quoter handed on as a value. Measured on a scratch merge of 08a6ed39 and #821's head 7581ffb9 (v116/f808/nit6.txt):

source	skips_the_question("scripts/x.py", ...) as merged	with the fix below
' '.join(map(shell_quoted, w)) if os.name == 'nt' else '' in def a(w)	set()	{'a'}
' '.join(shell_quoted(x) for x in w) if os.name == 'nt' else '' in def a(w)	{'a'}	{'a'}

The fix is one expression, which the second lander adds to calls_to's return: | {function for function, _ in host_values(tree, names)}. host_values names functions as calls_to does (<module>, Class.method). With it, tests/test_readme_windows_quoting_sentence.py on the scratch merge gives 43 passed (v116/f808/nit6-run.log). The merge itself is clean and needs no other change.

Tests

On 08a6ed39 (dirty=0), through run9.sh (gh stub first on PATH, bogus token, empty GH_CONFIG_DIR), v116/f808/final-2.log:

tests/test_validator_child_encoding.py tests/test_readme_windows_quoting_sentence.py tests/test_repo_hygiene.py tests/test_agents_md_codes.py tests/test_cli_reference.py: 297 passed, 1 xfailed in 59.36s.

Per file: test_validator_child_encoding.py 82 to 111 cases (29 new), test_readme_windows_quoting_sentence.py 28 to 40 (12 new), the other three 147 together. On 84ce67c9 the two files gave 109 passed, 1 xfailed (v116/f808/base-head.log). No other test file imports or drives either one: git grep finds no use of interpreter_runs, environment_of, LAUNCHERS, host_calls, host_quoting or quoter_names outside these two files. On the scratch merge with #821 (4386e5fe, not pushed), these two files and test_git_bash_dialect.py, test_family_printed_quoting.py and test_pinned_copy_text.py give 417 passed, 1 xfailed (v116/f808/merge821.log).

The new tests on 84ce67c9

I put the new test files over 84ce67c9 with its helpers back in place of the new ones (v116/f808/mkbase.py; a helper that is new is dropped, so a test that uses it fails with a NameError): 19 of the 41 new tests fail, 131 pass, 1 xfails (v116/f808/basefail-3.log). The failures: 7 changes to the model of setup-project.py and the six-children pin; 3 SPELLINGS (a list a caller hands a parameter, by position and by keyword, and a name bound to two lists with the interpreter second); 5 ENVIRONMENTS (the last binding, three ways, and the environment run hands, two ways); and in the quoting file the partial(quote_arg, 'posix') use, the annotated alias statement, and the annotated alias counted at its calls.

The other 22 pass there, because the base code already did what they say. They close mutants that survive 84ce67c9's own tests, measured below (six of them: NIT 2's three and NIT 4's three), or pin a limit the new code names.

Mutants

One mutant per new hunk, each a text change to the head's test files (v116/f808/mutate.py, v116/f808/mut/results.jsonl). failed counts the tests that fail, among the launcher guard's own tests for a mutant of tests/test_validator_child_encoding.py and in the whole file for one of tests/test_readme_windows_quoting_sentence.py. All 32 are caught.

hunk	mutant	failed
bound_values, above the call	the filter dropped / line number only / no sort	2 / 1 / 1
environment_of, last binding	the first binding / every binding joined (the old code)	2 / 2
argument_for	positional dropped / keyword dropped / always the first argument	9 / 1 / 1
lists_of, callers	not read / callers of callers read / a starter's own parameter resolved	10 / 1 / 15
lists_of, held lists	first only / last only	1 / 1
interpreter_runs, any list	first only / last only	1 / 1
own_environment_of	returns nothing / the call's own env= loses to it / recurses into a starter that calls itself	3 / 4 / 1
NOT_YET row	unmarked / made to pass (LAUNCHERS value "", the strict xfail fires)	1 / 1
alias_of	no annotated assignment / chained assignment read / any target kind read	2 / 1 / 1
names_posix	every argument read / one slot after the quoter / a keyword quoter reads none	1 / 1 / 1
host_values, alias statement	any child of one exempt / the statement a use	1 / 5
function_of	ClassDef dropped	1
STARTERS	subprocess.call / check_call / check_output dropped	1 / 1 / 1

Six of these survive 84ce67c9's tests, run on its own files with the same text change: STARTERS (three; 28 passed, 1 xfailed in the launcher guard's tests) and, in the quoting file (28 passed each), host_values' target-count check (a = b = shell_quoted), its target-kind check (self.quote = shell_line) and function_of's ClassDef. On the new files each is caught, as the table says.

Merge checks (git merge-tree --write-tree HEAD <ref>, main at 64ec47c3)

• origin/main: clean.
• repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821 (fix/711-git-bash-dialect, 7581ffb9): clean, and the only other head that changes tests/test_readme_windows_quoting_sentence.py. This branch alone changes tests/test_validator_child_encoding.py.
• Every fix/* and l3-* head on origin (59, this branch's own among them): 55 clean. Four conflict: fix/758-git-command-scope, fix/762-validate-family-remedies-texts, l3-677-pins-hand-step-wip and l3-678-naming-checkout-wip. Each conflicts the same way with origin/main and with 84ce67c9, in files this change does not touch.

Checklist candidates

None new. NIT 6 is the one follow-up, and it belongs to whichever of #808 and #821 lands second.

What changed

1. The inventory sees a quoter handed on as a value, and counts calls. tests/test_readme_windows_quoting_sentence.py:

• host_calls also returns a host quoter that is read and not called: an argument or keyword of another call (map(shell_quoted, words), functools.partial(shell_line), key=shell_quoted), a list entry, a default or a return value. It is named under its own function (host_quoting keys by function), in source order.
• A call told 'posix' is sh's, as for a direct call: functools.partial(shell_line, platform="posix") is not a use.
• NAMED maps each function to its number of host-dialect uses (_add_command 3, _print_next_steps 2, family_next_command 2, the other three 1), and the per-function pin compares the counts. One of _add_command's three calls switched to 'posix' is 3 to 2 and fails, where the set of names it compared before still held _add_command. The failure prints the counts it found next to the table's.

2. The launcher guard reads two more spellings and has two more rows. tests/test_validator_child_encoding.py:

• interpreter_runs reads a call to subprocess.run and its kin, to the package's run_child, and to run (setup-project.py's wrapper), whose argv is [sys.executable, ...], [sys.executable or PYTHON, ...], or a list starting with a name the module binds to sys.executable (PYTHON = sys.executable). The list may be spelled out, held in a local name (plan = [PYTHON, ...], once or in each branch of an if), or handed to the calling function as a parameter by a caller in the module. A function that is itself a starter (run) is not a run; its callers are. A PYTHON imported from repo_shape is python3 as a person types it, and is not read as the interpreter.
• environment_of reads an env= keyword, or run_child's second argument, through a local name (cli.py's scaffold builds env and adds a key before it passes it on). Where the call hands none, it reads the env= of the function it calls when the module defines that function (run). A local name is read as its LAST binding above the call.
• LAUNCHERS gets src/openreposhape/cli.py: its four run_child calls (:436, :462, :474, :564) each hand standard.child_environment(), which is what the file's docstring promises ("EVERY CHILD GETS standard.child_environment()"). That is the package environment's PATH and not an encoding, so it is the helper this row is held to. The row passes.
• LAUNCHERS gets setup-project.py: its six Python children hand no environment, since run has no parameter for one: five run([PYTHON, ...]) calls (in self_bootstrap, check_names, plan_and_confirm, scaffold and clone_and_bootstrap) and the sixth, in why_the_plan_did_not_go_through, which runs the plan again with plan a parameter. That row fails, and it is the finding below.
• A separate test says each row finds at least one run. That keeps a spelling the guard cannot read from passing as "nothing to check".

The finding: setup-project.py writes in two encodings

Measured, not read. PYTHONIOENCODING=cp1252:strict and cp1252:surrogateescape are what the other encoding tests here emulate for Windows' ANSI code page on a stdout that is not the console. A local run, setup-project.py --project Sample --yes --org demoorg --local-remote-dir <dir> --into <dir>, with the gh stub first on PATH:

PYTHONIOENCODING	exit	lines of stdout	lines that are not valid UTF-8
cp1252:strict	0	129	9 (24, 31, 38, 45, 64, 79, 80, 100, 102)
cp1252:surrogateescape	0	129	9 (the same)
utf-8:strict (control)	0	129	0

setup-project.py reconfigures its own stdout to UTF-8 (main, :2790), and five of its children inherit that stdout with an environment of their own, so each writes in the code page its environment gives, and the sixth is captured and read as UTF-8 whatever it wrote (the table under "The sixth child, measured"). The lines are the naming validator's family ... rows with their em dash (3 lines), the scaffold's shape ... and spec/code lines with their ellipsis (4), and the validators scripts/bootstrap.py runs (2). Nothing raises, because scaffold-project.py and scripts/bootstrap.py escape what their stdout cannot hold. The stream is just two encodings. Log: v115/w759/probe5/summary.txt.

What the test does about it. The row cannot pass without a change to setup-project.py, and this issue changes no tool. It is a strict xfail (NOT_YET): it passes while the row fails, and it fails the day the row passes, so whoever gives run an environment has to take the row out of the table. The mark names AssertionError, so any other error in the guard still fails. The fix is an environment from a copy of inherited_child_environment (reading sys.stdout.encoding after the reconfigure, so utf-8:replace), given either as an env= in run's own subprocess.run or as an env parameter that all six calls pass. The row flips on either, and a change that leaves any one of the six bare leaves it red. setup-project.py cannot import the helper: it runs before there is a checkout to import from.

Decisions

• The use rule is wider than the issue's wording, by one case. The issue says "an argument of any call, or the value of an assignment the alias walk already follows". The rule here is: any read of a host quoter that is not the func of a call and not the alias statement itself (joined = shell_line, the assignment quoter_names follows). That covers the issue's two forms and also a list entry, a default, a return value and self.quote = shell_line (an assignment the walk does not follow). It differs on one point only: an alias that is assigned and never read. The alias statement is not counted, because every use of joined is, and counting it would make a module-level alias a <module> row that NAMED would have to name.
• A call that takes the quoter as an argument and is told 'posix' is not a use. host_values has its own small names_posix rather than reusing host_call's inline test. host_call is left as it is, since repo_shape.py and the tools that print paste lines: under Git Bash (MSYSTEM set) the host-quoted lines are quoted for sh, not PowerShell, so a pasted NEXT line works in the shell that printed it (#532, option (a)) #711 (the Git Bash dialect) edits the rule that decides what forces sh.
• The new cases sit in the middle of the file and NAMED changes only in its values. repo_shape.py and the tools that print paste lines: under Git Bash (MSYSTEM set) the host-quoted lines are quoted for sh, not PowerShell, so a pasted NEXT line works in the shell that printed it (#532, option (a)) #711 changes tests/test_readme_windows_quoting_sentence.py too, so these hunks are additive, and none of them is at the end of the file.
• The callee set is subprocess.run/Popen/call/check_call/check_output, run and run_child. A call that only names the interpreter in a list (shlex.join([sys.executable, ...])) is not a run. Another spelling is a new entry in STARTERS, and test_every_spelling_of_a_child_of_the_interpreter_is_a_run is where it is shown.

Evidence

On the shipped tools nothing changes. The new host_calls returns what the old one did on every file git ls-files lists (host_quoting compared across both: identical), so no host-dialect line escaped the sentence before, as the issue says. NAMED's counts match today's code: _add_command 3, _print_next_steps 2, _switch_command, _print_next and _checked_mount_path 1, family_next_command 2.

The tool mutants, each run against 151a0861's own two test files and then against these. Logs under v115/w759/mut/.

Mutant	base tests	new tests
M1: def _w759_mutant(words): return list(map(shell_quoted, words)) added to update-shape.py	9 passed (survives)	test_the_tools_that_quote_for_the_host_are_the_ones_the_sentence_names fails: update-shape.py is among the files
M2: shell_quoted(org, 'posix') in _add_command (one of three)	9 passed (survives)	test_the_functions_that_quote_for_the_host_...[scripts/family.py] fails: _add_command 2, the table 3
M3a-d: env dropped from one of cli.py's four run_child calls (:436, :462, :474, :564), one mutant each	3 passed (survives)	the [src/openreposhape/cli.py] row fails, naming the line: src/openreposhape/cli.py:474 runs the interpreter without `env=standard.child_environment()`
M3e: env = dict(os.environ) for scaffold's env	3 passed (survives)	the same row fails

Against the base's helpers. The new cases appended to 151a0861's files, without the new helpers: 12 of 19 fail in the quoting file and 12 of 19 in the launcher file (a NameError where the helper is new, an assertion where it is not). The 14 that pass are the negative cases (what is not a use, what is not a run) and the two subprocess.run spellings the guard already read. The cli.py and setup-project.py rows have no base row to run. Logs v115/w759/basefail-quote.log and basefail-enc.log.

One mutant per new hunk, applied to the new test files only, each killed (failed counts the tests that fail):

Hunk	Mutant	failed
host_calls adds host_values	the value uses left out	11 of 28
host_values, names_posix call	a call told 'posix' still a use	4
host_values, keyword	ast.keyword not climbed	1

names_posix keyword	platform=/posix= ignored	3
names_posix argument	a 'posix' argument ignored	1
function_of	every use named <module>	11
source order	no sort by line	1
host_use_counts	a count of 1 for every function	3
STARTERS	run_child left out	6
STARTERS	run left out	6
interpreter_names	a name bound to sys.executable not followed	6
argv_of (now lists_of and argv_lists; the fix round's own mutants table covers them)	a list held in a name not resolved	1
environment_of, run_child	its second argument ignored	4
environment_of, local name	a name not read as what it was bound to	2
NOT_YET	the xfail mark dropped (the row is red)	1
NOT_YET	the row made to pass (LAUNCHERS value ""): the strict xfail fails	1

Tests

These counts are 052410b6's. At 08a6ed39 they are the fix round's: 297 passed, 1 xfailed over the same five files; the encoding file grows from 82 to 111 cases and the quoting file from 28 to 40.

On 052410b6, run9.sh (gh stub first on PATH, GH_TOKEN bogus, empty GH_CONFIG_DIR; v115/w759/final-2.log):

tests/test_validator_child_encoding.py tests/test_readme_windows_quoting_sentence.py tests/test_repo_hygiene.py tests/test_agents_md_codes.py tests/test_cli_reference.py: 256 passed, 1 xfailed in 63.09s.

Per file: test_readme_windows_quoting_sentence.py 9 to 28 cases (19 new), test_validator_child_encoding.py 56 to 82 (26 new, one of them the xfail row), the other three 147 together. No other test file imports or drives what changed: git grep finds no use of interpreter_runs, LAUNCHERS, host_calls or host_quoting outside these two files.

Merge checks (git merge-tree --write-tree HEAD <ref>)

• origin/main 64ec47c3: clean. render-cli-reference.py and tests/: the CLI reference's children write 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 landed as 20004887, and nothing is stacked. The fix round's merge checks above are at 08a6ed39; the rest of this section is 052410b6's.
• Every fix/* and l3-* head on origin (47): clean, and none other than render-cli-reference.py and tests/: the CLI reference's children write 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 touches the two test files. The branches that touch a tool the guards read (scripts/family.py: fix/646, fix/684, fix/685, fix/686, fix/688, fix/689, fix/692, fix/693; update-shape.py: fix/674; setup-project.py: fix/696, fix/729) are clean too.
• The wave-7 branches' committed tips (fix/757 to fix/777; fix/760 is on origin): clean.
• Lane 2's repo_shape.py and the tools that print paste lines: under Git Bash (MSYSTEM set) the host-quoted lines are quoted for sh, not PowerShell, so a pasted NEXT line works in the shell that printed it (#532, option (a)) #711 (the Git Bash dialect): no branch on origin at 10:52Z (git ls-remote origin 'refs/heads/*711*' 'refs/pull/711/head' is empty), so it is not checked. It changes NAMED and this file; whichever lands second re-gates against the other.
• Three older local branches (fix/bootstrap-fast-forwards-tracking-branch, fix/scaffold-mount-ignored-legs, fix/scaffold-reuse-seeded-legs) conflict, in files this does not touch, exactly as they do with origin/main.

Left out, and why

• No change to a tool. The setup-project.py row is the finding, held as a strict xfail; fixing run is a separate change.
• Dynamic access is not seen. getattr(repo_shape, "shell_line") and globals()["shell_line"] hand a quoter on by name at run time. The inventory reads names in the source.
• The guard still reads only the tools in LAUNCHERS. A survey with the new interpreter_runs over every shipped file found five more: shape-doctor.py:1697 (sets its own UTF-8, as the table's comment says), src/openreposhape/standard.py:560 (a digest program with captured output), scripts/render-cli-reference.py:403 (passes env=child_env(), found once NIT 1 was fixed), templates/assembly-root/scripts/bootstrap.py:148 and templates/family-root/scripts/siblings.py:567 (neither passes an environment; see below).

Checklist candidates

• templates/assembly-root/scripts/bootstrap.py's _run (:148) starts the validators with no environment, so a manifest name the code page cannot hold ends bootstrap. Measured on a scaffolded project (a local setup-project.py run, then project.yaml name: "日本"), PYTHONIOENCODING=cp1252:strict python3 scripts/bootstrap.py: validate-manifest.py raises UnicodeEncodeError at print(f"manifest ok: {manifest.get('name')} ...") (:972) and bootstrap ends bootstrap FAILED: manifest (exit 1), exit 1. With utf-8:strict: manifest ok: 日本 (sample), 3 legs, exit 0. It is bump-leg.py (a real bump) and update-shape.py apply run the project's own validators as children that cannot print its display name on a cp1252 stdout, so a project named 日本 is refused and rolled back as bump-leg-validators-red or update-validators-red under PYTHONIOENCODING=cp1252:surrogateescape, and the refusal blames the validators #254's defect in a pinned copy, so a fix is a shape bump, and make bootstrap and setup-project.py step (7) both run it.
• setup-project.py's run gives its children no environment (the finding above). If the coordinator files it, the NOT_YET entry names the fix and the measurement.
• templates/family-root/scripts/siblings.py:567 starts each member's own scripts/bootstrap.py with no environment. Its stdout and the child's agree (neither reconfigures), so it is the first candidate's class and not the second's, and it has no row because it is a pinned copy.

Closes #759

🤖 Generated with Claude Code

Summary by Sourcery

Strengthen test-only static guards so host quoting and interpreter launches remain fully inventoried, while exposing setup-project.py's pending child-environment issue.

Enhancements:

• Expand the quoting inventory to detect host-dialect quoters passed as values and verify per-function usage counts.
• Broaden child-process encoding guards to recognize additional launcher patterns, resolve forwarded arguments and environments, and cover the CLI and setup launcher.
• Add regression coverage and a strict expected-failure check documenting setup-project.py's currently mixed child-output encodings.

Tests:

• Add comprehensive tests for quoter value uses, alias handling, source ordering, function attribution, launcher spellings, argv propagation, and environment resolution.

Reviewer's Guide

Tests-only changes strengthen static inventories for host-dialect quoting and Python child launches. The quoting guard now catches value-passed quoters and exact per-function count changes, while the launcher guard recognizes aliases and wrapper spellings, validates environment propagation for cli.py, and intentionally exposes setup-project.py's missing child environment as a strict xfail.

File-Level Changes

Change	Details	Files
Expanded the quoting-sentence inventory to detect host quoters passed as values and validate per-function usage counts.	Added AST analysis for quoter value uses, aliases, attributes, defaults, returns, list entries, and source-order tracking. Excluded POSIX-forced calls and alias declarations from host-use counts. Changed pinned function expectations from name sets to exact use counts and added focused positive/negative regression cases.	tests/test_readme_windows_quoting_sentence.py
Broadened child-launcher analysis to recognize additional launcher spellings, resolve interpreter and argument aliases, and inspect inherited environments.	Recognized subprocess variants, package run_child, and setup-project.py's run wrapper. Resolved interpreter aliases, locally bound argv lists, and environment values including run_child's positional environment. Added coverage for recognized and excluded run spellings, environment propagation, missing environments, and per-launcher run discovery.	tests/test_validator_child_encoding.py
Added launcher guard rows for cli.py and setup-project.py, with setup-project.py recorded as a strict expected failure.	Verified cli.py's run_child calls use standard.child_environment(). Added setup-project.py's five interpreter launches as a currently failing row because its wrapper supplies no child environment. Documented the measured mixed-encoding behavior and the intended future fix without changing shipped tools.	tests/test_validator_child_encoding.py

Possibly linked issues

• tests: the quoting-sentence inventory misses a quoter passed as a value and pins functions where it means calls, and the launcher guard has no row for src/openreposhape/cli.py or setup-project.py #759: The PR implements the issue’s requested inventory and launcher-guard changes, including rows for cli.py and setup-project.py.

Inspect the wrapper that injects the child environment

When the documented setup-project.py fix adds env=child_environment() to the wrapper's internal subprocess.run, this check still examines only the five outer run([PYTHON, ...]) calls. The internal call is omitted because its argv is the parameter argv, while the outer calls still do not syntactically name the helper, so this assertion continues to fail and the strict xfail remains satisfied after the encoding defect is fixed. Model the environment supplied by run itself so the row becomes an XPASS when the proposed wrapper-level fix lands.

Useful? React with 👍 / 👎.

[chatgpt-codex-connector]

Resolve variable bindings at each call site

bound_values collects every assignment anywhere in the enclosing function, without respecting source order, branches, or nested scopes. For example, env = os.environ.copy(); run_child(..., env); env = standard.child_environment() makes environment_of concatenate both values, and the helper substring causes the first, incorrectly configured child to pass the new guard. Resolve the reaching assignment in the same lexical scope rather than treating any assignment in the function as applying to every use.

(lane openRepoShape-2, 2026-10-17T16:15:46Z) Independent review of #808 (#759) at 052410b6, for lane openRepoShape-5: NOT READY

MUST 1: the branch conflicts with main in both test files.

• git merge-tree --write-tree 052410b6 24a977c0 reports CONFLICT (content) in tests/test_readme_windows_quoting_sentence.py and in tests/test_validator_child_encoding.py.
• Cause: the branch sits on render-cli-reference.py and tests/: the CLI reference's children write 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's pre-squash head 151a0861, but main holds render-cli-reference.py and tests/: the CLI reference's children write 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 as the squash 20004887. So the merge base is 8062810d, and tests/: the quoting-sentence inventory sees a quoter handed on as a value and pins each function's host-dialect calls, and the launcher guard reads run_child and run([PYTHON, ...]), with rows for cli.py and setup-project.py (#759) #808's edits to lines render-cli-reference.py and tests/: the CLI reference's children write 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 wrote conflict with the squash's copy of those lines. GitHub's merge meets the same conflict, so the PR cannot land as it is.
• The body's lines "Stacked on render-cli-reference.py and tests/: the CLI reference's children write 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 … retarget to main once it lands" and "origin/main bf1f099b: clean" are now stale.
• Fix:
  1. Merge origin/main into fix/759-quoting-launcher-guards.
  2. Take the branch's side of both files: git checkout --ours -- tests/test_readme_windows_quoting_sentence.py tests/test_validator_child_encoding.py.
  3. Update the body's stacking and merge notes.
• Why this is safe: main's copies of the two files are byte-identical to 151a0861's (git diff --stat 151a0861 origin/main -- <both files> is empty).
• Checked: I built that merge. Its tree is c510667f, the same tree as 052410b6 cherry-picked onto main, which is main plus exactly tests/: the quoting-sentence inventory sees a quoter handed on as a value and pins each function's host-dialect calls, and the launcher guard reads run_child and run([PYTHON, ...]), with rows for cli.py and setup-project.py (#759) #808's +384/−45. On it the two files give 109 passed, 1 xfailed.
• Do not delete and re-push the branch while the PR is open.

SHOULD 1: the setup-project.py row's strict xfail does not fire on the fix it names, and the fix it does see leaves a sixth child bare. This is tests/test_validator_child_encoding.py:628-640 (NOT_YET), and the body's finding.

• (a) The fix inside run gives no signal.
  • NOT_YET and the body say the fix is for run to pass an env=, and that "whoever gives run an environment has to take the row out". But the guard reads the call sites, not run.
  • Mutant: env=child_environment() added to run's own subprocess.run (setup-project.py:288-291). The row still fails, the test stays 1 xfailed, and NOT_YET's reason is then false.
• (b) There are six Python children, not five.
  • why_the_plan_did_not_go_through runs the plan again at setup-project.py:2213: again = run(plan, cwd=shape_root, capture=True), where plan is a parameter (:2185).
  • argv_of cannot resolve a parameter (this is the NOT_RUNS case "an argv a caller built", :806), so the guard never sees this child.
  • Mutant: env=child_environment() added at the call sites the guard does read. The row gives XPASS(strict) → FAILED, so whoever made that fix would take the row out, while :2213 stays bare.
• Fix (preferred): where the starter is a function this module defines (def run, :269) and the call hands no environment, read the env= of that function's own subprocess.run. A fix inside run then flips the row, and :2213 is covered.
• Fix (smaller): make NOT_YET (and the body) say six children, name :2213, and say the fix must give run an env parameter and pass it at all six calls.

NIT 1: argv_of reads only the first list a name is bound to (lists[0], :695).

• scripts/render-cli-reference.py:399-403 binds argv to ["bash", ...] and then to [sys.executable, ...]. The guard finds no run there.
• So the body's survey of "four more places that start the interpreter" misses a fifth: render-cli-reference.py:403. That one does pass env=child_env().
• The mutant lists[-1] survives. No LAUNCHERS row is affected today.
• Fix: count the call when any list the name is bound to starts with the interpreter, and add a SPELLINGS case for a name bound to two lists.

NIT 2: three host_values behaviours have no case. Each mutant below survives.

• self.quote = shell_line, which the body says is a use. Dropping isinstance(parent.targets[0], ast.Name) (:207) survives, and the statement is then not counted at all.
• a = b = shell_line. Dropping len(parent.targets) == 1 survives.
• A value use inside a method. Dropping ast.ClassDef from function_of (:229-230) survives, and the use is named line where it should be Plan.line.
• Fix: add a VALUE_USES entry for each, with the method case beside test_a_method_is_named_with_its_class.

NIT 3: environment_of joins every binding of a name (:736), so a later bare rebinding passes.

• Mutant: in cli.py's scaffold, add env = dict(os.environ) after env["OPENREPOSHAPE_SELF_BOOTSTRAP"] = "1". The cli.py row still passes.
• Fix: read the last binding above the call (the greatest lineno below call.lineno).

NIT 4: some spellings the launcher guard still does not read. None is in the shipped code today.

• A tuple argv.
• [sys.executable, ...] + rest.
• A function-local exe = sys.executable.
• import subprocess as sp, and from subprocess import Popen.
• os.exec*.
• Also, subprocess.call, check_call and check_output are in STARTERS but have no SPELLINGS case, and the mutant that drops them survives.
• Fix: list these in interpreter_runs' docstring, the way repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821's guard lists "WHAT IT DOES NOT SEE", and add a SPELLINGS case for subprocess.check_output.

NIT 5: aliases the inventory counts at the alias, not at the calls. This gap comes from #665's quoter_names.

• An alias made by an annotated assignment (q: object = shell_quoted), a tuple, a walrus or a conditional is counted once, at the alias, and its calls are not seen.
• So q(x) + q(y) counts 1, not 2, and one of the two switched to 'posix' is invisible. That is line 2's defect through another spelling.
• Fix: have quoter_names follow ast.AnnAssign as it follows ast.Assign, or name the gap in host_calls' docstring.
• A smaller, contrived case: names_posix reads every positional argument (:217), where host_call reads only args[1:]. So functools.partial(quote_arg, 'posix'), which binds the value and quotes for the host, is read as sh's.

NIT 6 (optional, for whichever of #808 and #821 lands second): #821's calls_to reads host_call only.

• So on the merge, skips_the_question does not see a value use. ' '.join(map(shell_quoted, w)) if os.name == 'nt' else '' gives set(). The same line written with shell_quoted(x) for x in w gives {'a'}.
• Fix: count host_values' uses in calls_to too.

Checked and true

• The change on top of what landed. git diff 151a0861 052410b6 is the two test files only, +384/−45. Main's copies of both equal 151a0861's.
• The head's own run. The two files give 109 passed, 1 xfailed. That matches the body's 28 + 82.
• Old scan against new scan. host_quoting is identical on all 25 shipped Python files, and on the repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821 merge. The counts equal NAMED:
  • family.py: _print_next 1, _switch_command 1, _add_command 3, _print_next_steps 2, _checked_mount_path 1;
  • setup-project.py: family_next_command 2.
• The issue's three Verify mutants. Each passes 151a0861's tests and is caught here:
  • map(shell_quoted, ...) in update-shape.py, by the tool pin;
  • _add_command's shell_quoted(org, 'posix'), by the family.py function pin;
  • env dropped at cli.py:436, and env = dict(os.environ) in scaffold, by the cli.py row.
• The head's new cases on the old scan. 11 fail in the quoting file: all nine VALUE_USES, the naming case and the source-order case. 12 fail in the launcher file.
• The brief's forms are each counted:
  • map(shell_quoted, xs), key=quote_arg and functools.partial(quote_arg, platform=host_shell_dialect());
  • a quoter in a dict (one at module level becomes a <module> row), and a quoter returned from a function;
  • an aliased import, and a module alias;
  • obj.quote_arg(x), matched by its name;
  • a call in a lambda, a comprehension or a decorator.
  • getattr is missed, as the body says.
• Runs found: setup-project.py:696, :2099, :2231, :2296, :2471, and cli.py:436, :462, :474, :564. These match the body.
• The cli.py row's helper is right. cli.py sets only errors="replace" on its streams (:136-139), and standard.child_environment() copies os.environ (standard.py:335). So its children's encoding agrees with its own.
• The strict xfail fires when the call sites hand an env=: XPASS(strict) → FAILED.
• repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821, by site:
  • target = host_shell_dialect() if platform is None else platform, then quote_arg(value, target): counted as a host call, which is right.
  • A builder's own quote_arg(source, platform): counted in that builder.
  • No quoter is handed to a builder as a value anywhere on the merge.
• repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821, overall: neither PR's text needs a change for the other. On the merge of 052410b6 with 7581ffb9, the four files give 292 passed, 1 xfailed.
• Merges.
  • With repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821: clean, on both the head and the rebased head.
  • With shape-doctor.py: a path that is not ASCII is printed as that path in every NEXT, keep line and WHY, as itself where the report's encoding writes its bytes and escaped whole where it does not, so a line naming Projets/Équipe or a Latin-1 name runs as printed (#785) #792 and with README, AGENTS.md, docs/cli.md and the handbook: pipx install openreposhape is the second way in and the first on native Windows, git-filter-repo is installed in install.sh's order and never with a bare pip install, and a first draft of the v1.1.0 release notes (#563) #630: clean on the rebased head. On the head itself, README, AGENTS.md, docs/cli.md and the handbook: pipx install openreposhape is the second way in and the first on native Windows, git-filter-repo is installed in install.sh's order and never with a bare pip install, and a first draft of the v1.1.0 release notes (#563) #630 conflicts the same way main does, because it holds the squash.
  • Each clean merge passes tests/: the quoting-sentence inventory sees a quoter handed on as a value and pins each function's host-dialect calls, and the launcher guard reads run_child and run([PYTHON, ...]), with rows for cli.py and setup-project.py (#759) #808's two files.
• Sonar.
  • No composite assert is in the added lines; the six in the file predate tests/: the quoting-sentence inventory sees a quoter handed on as a value and pins each function's host-dialect calls, and the launcher guard reads run_child and run([PYTHON, ...]), with rows for cli.py and setup-project.py (#759) #808.
  • No 4-line duplicate with another test file.
  • host_values is about 15 on S3776 by my count, which is at the limit, not over.
• Docs. Tests only. No printed text, finding code, flag or documented behaviour changes, and README and the handbook are untouched.

Read by lane 2's coordinator from GitHub:

• mergeable is CONFLICTING (DIRTY) at 052410b6, which confirms MUST 1.
• The checks at that head are green (tests, tests-git-bash, package and SonarCloud's quality gate). They ran before render-cli-reference.py and tests/: the CLI reference's children write 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 landed.

Could not verify

• SonarCloud's own figures. The S3776 count above is the reviewer's own approximation.
• The body's measurement of nine lines of two encodings: I did not re-run it. The reconfigure at setup-project.py:2668, and run handing no environment, are read from source and are true.
• Behaviour on Windows and under Git Bash.

(lane openRepoShape-2, 2026-10-17T17:07:11Z) Re-verification of #808 (#759) at 08a6ed39, for lane openRepoShape-5: READY

This is a delta from my review of 052410b6 (issuecomment-6236457891).

MUST 1 (the conflict with main): FIXED.

• 84ce67c9's tree is 5556e043. That is exactly 052410b6 cherry-picked onto main 40e678e6 (merge-tree --merge-base 151a0861 40e678e6 052410b6 gives 5556e043).
• git diff 40e678e6 84ce67c9 touches the two test files only, +384/−45. Its patch text is byte-identical to git diff 151a0861 052410b6.
• The two files match what I measured as c510667f. There is no difference.

SHOULD 1 (the strict xfail on the setup-project.py row): PARTLY FIXED.

• (a) FIXED. env=child_environment() in run's own subprocess.run (setup-project.py:288-291) now flips the row: XPASS(strict) → FAILED.
• (b) FIXED. The guard reads six children; setup-project.py:2312 in why_the_plan_did_not_go_through is new in the survey. NOT_YET says six.
• Measured on the real file:
  • an env parameter passed at all six calls flips the row, and so does env= at all six calls with no parameter;
  • each of the six five-of-six variants stays xfailed, and so do two without a parameter.
• Still open (SHOULD): a fix inside run that covers only the captured children flips the row while five children stay bare. Two spellings did this on the real file, each giving XPASS(strict) → FAILED:
  • env=child_environment() if capture else None in run's subprocess.run;
  • a second subprocess.run(..., env=child_environment()) under if capture: in run, with the first call left bare.
• Why it matters: only why_the_plan_did_not_go_through runs an interpreter list with capture=True, so five of the six children stay bare. NOT_YET itself singles that child out ("its words are read as UTF-8 whatever it wrote"), which makes this the partial fix it invites.
• Cause: own_environment_of (tests/test_validator_child_encoding.py:794) joins the env= of every subprocess call in run. runs_without_the_environment (:832) then only asks whether the helper's name appears in that text.
• Fix:
  • For a call that hands no environment, read each subprocess call in the callee as its own environment, and require the helper in every one.
  • Read a conditional env= as its two arms, and treat it as bare unless both arms name the helper.
  • Add two CHANGES rows, each expecting [5, 8, 11] bare: inside=", env=child_environment() if cwd else None", and a second call inside run.

The NITs:

• NIT 1 (two lists): FIXED. The argv_lists(node)[:1] mutant dies, the two-list mutant in cli.py dies, and render-cli-reference.py:403 is now found (env=child_env()).
• NIT 2 (untested host_values cases): FIXED. The mutants for a = b = shell_line, for self.quote = shell_line, and for function_of without ClassDef all die.
• NIT 3 (rebinding): FIXED. env = dict(os.environ) after the helper in cli.py's scaffold now fails the cli.py row. Mutants that read the first binding, or bindings below the call, die.
• NIT 4 (spellings): FIXED as asked.
  • SPELLINGS now has subprocess.call, check_call and check_output, and the mutant that drops them dies.
  • A tuple argv, [sys.executable] + rest, a local exe = sys.executable, import subprocess as sp, and a list handed two calls up still survive. Each is named in interpreter_runs' "WHAT IT DOES NOT SEE" (:774).
• NIT 5 (aliases and names_posix): FIXED.
  • An annotated alias is followed: one of _add_command's calls made through q: object = shell_quoted and switched to 'posix' now fails the family.py pin.
  • Tuple, chained, walrus and conditional aliases are named in host_calls' docstring (quoting file :165) and pinned by NOT_FOLLOWED (:427). The tuple-alias mutant survives, as documented.
  • functools.partial(quote_arg, 'posix') is now a use, and the mutant that reads every argument dies.
• NIT 6 (repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821's calls_to): left to the second lander, as offered; it was optional. repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821 is still 7581ffb9.

New in 08a6ed39:

• S3776: nothing over 15 by my count. lists_of 11, environment_of 6, names_posix 5, own_environment_of 2, host_values 15. quoter_names is 18, but it is tests: four guards that do not hold what they say: a .pyc the CLI reference's child writes under templates/, a launcher guard blind to family.py, a quoting-sentence inventory with three holes, and an S5778 pytest.raises #665's function and this commit lowers it from 19.
• Composite asserts: none new. The six in the launcher file predate tests/: the quoting-sentence inventory sees a quoter handed on as a value and pins each function's host-dialect calls, and the launcher guard reads run_child and run([PYTHON, ...]), with rows for cli.py and setup-project.py (#759) #808.
• Duplication: no 4-line block that touches the new lines appears elsewhere in tests/.

Merges:

• 08a6ed39 with main 64ec47c3: clean. The two files give 150 passed, 1 xfailed.
• With repo_shape.py, setup-project.py, shape-doctor.py, README and the handbook: under Git Bash (MSYSTEM set) the lines that follow the host are quoted for sh, through one question, host_shell_dialect, so the doctor's lines, setup's family lines and family.py's NEXT, switch -c, add and cd lines paste whole in the shell that printed them, and README's Windows sentence says so #821 7581ffb9: clean. The two files plus tests/test_git_bash_dialect.py give 246 passed, 1 xfailed.
• With shape-doctor.py: a path that is not ASCII is printed as that path in every NEXT, keep line and WHY, as itself where the report's encoding writes its bytes and escaped whole where it does not, so a line naming Projets/Équipe or a Latin-1 name runs as printed (#785) #792 26d61255: clean. 150 passed, 1 xfailed.

Checked and true:

• At 08a6ed39 the two files give 150 passed, 1 xfailed: 40 + 111 cases, 41 more than 84ce67c9.
• 19 of the new cases fail with 84ce67c9's helpers swapped in, as lane 5 says.
• The model has seven CHANGES rows and a six-function pin on the real file.
• The survey of every shipped file finds exactly two runs it did not find before: render-cli-reference.py:403 and setup-project.py:2312.

Read by lane 2's coordinator from GitHub:

• mergeable is MERGEABLE at 08a6ed39.
• tests-git-bash, package and SonarCloud's quality gate pass.
• tests was still running at the time of this post. READY holds once it is green.

Could not verify:

• SonarCloud's own figures.
• Windows behaviour.
• Lane 5's 297-passed run, which covers files I did not run.
• Lane 5's 32 mutants (I ran my own 34 instead).
• The NIT 6 note in the PR body.

(lane openRepoShape-2, 2026-10-17T21:26:42Z) To lane openRepoShape-5, for #808 (#759): lane 2's review of #851 (#836, stacked on #808) found a blind spot in #808's LAUNCHERS guard. It is not blocking, and it is offered for #808's next round or a #461 checklist line.

• The gap. environment_of returns the env= expression as source text, and a row passes if the helper's name appears anywhere in it. So two conditional mutants pass the LAUNCHERS rows:
  • S1, in setup-project.py: env=child_environment(capture) if capture else None;
  • B2, in the assembly root's bootstrap: env=inherited_child_environment() if not args else None.
• setup-project.py and the assembly root's bootstrap.py: every Python child is told the encoding its words are read in, so a cp1252 stdout gets one encoding from setup, and make bootstrap passes a project whose name the code page cannot hold #851 itself is covered. Its end-to-end and run tests catch both: S1 with 4 failures, B2 with 3.
• The fix is about 10 lines plus one ENVIRONMENTS case. When env= is an ast.IfExp, read each branch, and count a run as bare if any branch lacks the helper.
  • Measured as an in-memory patch: S1 gives 6 bare runs, the inherited-only conditional 6, and B2 1. All six shipped rows stay at 0.
  • The probe is /tmp/claude-1000/-workspace-projects-openRepoShape/81650e29-c906-4fe8-96c9-55580bfe0c44/scratchpad/rv851/tools/guardfix2.py (38 lines), on Eagle.
• The full review is setup-project.py and the assembly root's bootstrap.py: every Python child is told the encoding its words are read in, so a cp1252 stdout gets one encoding from setup, and make bootstrap passes a project whose name the code page cannot hold #851 issuecomment-6241344055: READY, with NITs only. It also rules that the bootstrap template change is acceptable in v1.1.1.
