Claim: #712 (comment)

What changed and why

Issue #712 gathers lane 4's checklist lines L4-103, L4-104, L4-106 and L4-144 on the assembly root's lockstep gate, templates/assembly-root/scripts/validate-pins.py, with the riders L4-105, L4-143 and L4-102. This PR takes all seven, the two riders L4-143 and L4-102 included. It is milestone v1.1.1 and lands after the v1.1.0 tag.

Measured on main 24a977c0, Python 3.12.3, with a scaffolded Atlas:

case	main	this branch
contracts/ at 000 or r--	PermissionError traceback, exit 1	REFUSED yaml-unreadable: contracts/spec-pin.yaml: cannot be read (Permission denied), exit 2
contracts/spec-pin.yaml at 000	REFUSED yaml-unreadable: <abs>: [Errno 13] Permission denied: '<abs>' + THE LOCKSTEP RULE's remedy	the line above, with its own remedy

../openXdox at 000 beside a root that declares openXdox (fix round 1, S1)	PermissionError: [Errno 13] Permission denied: '<BESIDE>/openXdox/.git', exit 1	FINDING neutral-pin-source-unreadable: contracts/openxdox-pin.yaml: <BESIDE>/openXdox (sibling checkout (<BESIDE>/openXdox)) could not answer for testorg/openXdox @ <commit>: Permission denied, exit 1
scalar neutral_product_pins: openXdox + --pin-source openXdox=../nowhere	not used — project.yaml declares no neutral-product pin.	not used — project.yaml's neutral_product_pins is not a list, so it declares no neutral-product pin (see the manifest-neutral-product-pins finding).

• L4-103. The five Path.is_file() sites (leg pin, shape pin, each shape copy, each neutral-product pin, the manifest) are _is_file now: validate-pins.py (assembly-root template): a .github/workflows/ directory that this user cannot list or search is a workflow-unreadable refusal naming it, exit 2, so the project's pins gate no longer ends in a PermissionError traceback, exit 1, where a workflow file it cannot open already was one (#434) #633's _is_a, so every Python answers alike, and a refused stat is a refusal naming the file. A NUL in a role or a product (a ValueError) is still "no file", as is_file() answered. A shape copy whose open is refused, which passed its stat and ended in file_sha256's traceback on every Python, is the same refusal. A copy had no id for one, so it is the new shape-copy-unreadable, beside shape-copy-missing and shape-copy-drift; the YAML files keep yaml-unreadable.
• Checkouts this user cannot search (fix round 1, RV827's S1). _check_pin_digest's (submodule / ".git").exists() and resolve_neutral_pin_source's (sibling / ".git").exists() raised PermissionError on 3.11 to 3.13; from 3.14 the leg would have read as an uninitialized submodule and the sibling been passed over for gh api. Both ask _is_there (_is_a with any kind; a NUL is nothing there, as exists() answered). The leg is the new pin-submodule-unreadable, beside pin-submodule-uninitialized, naming the .git it could not reach, with the cause's advice; the sibling is there, so it is the source, and the pin's neutral-pin-source-unreadable finding says it could not answer.
• L4-104. _load wraps load_yaml. A file this user cannot open is read off the OSError the refusal is chained from (since load_yaml was written), and named relative to the root, POSIX, once: <rel>: cannot be read (<reason>), with a remedy of its own, so main adds no lockstep remedy. It does not depend on new library words, so a root whose scripts/repo_shape.py is older than its validate-pins.py reads the same (repo_shape.py's Refusal gives every refusal built without a remediation the assembly root's own (run git submodule update --init --recursive, then python3 scripts/validate-pins.py ... contracts/<leg>-pin.yaml), so in a family holder family.py add over an unparsable .gitmodules (git-failed), bump on a family.yaml of the wrong kind, and the holder's own validate-family.py on a short pin.commit each tell the operator to run a file no holder carries and to move a leg pin a holder does not have #370, Pinned shape copies: AGENTS-shape.md's CONTRACTS_DIR sentence is false for every scaffolded root, and the chain WARNING offers remedies the scaffold lacks (one shape bump before the v1.1.0 tag) #610). repo_shape.load_yaml itself names the path once for every caller: <path>: cannot be read (<reason>).
• One rule for every file the gate names (coordinator's ruling): load_yaml's other refusals here (not UTF-8, not parsable) keep their id, words and remedy and name the file relative to the root; so do not a mapping (four YAML files), shape-pin-missing, manifest-missing and manifest-no-legs, which named the absolute path raw.
• L4-105. A permission keeps its words (a workflow) or gets bump-leg.py's (bump-leg.py: a workflow file, a .github/workflows/ directory or a leg pin that this user cannot open ends the run in a PermissionError traceback, exit 1, under --dry-run as well, because cmd_bump and plan_workflows read them with no handler and main() catches Refusal and CommandFailed only, so no refusal names the file or says to make it readable #383) for a pin, the manifest or a copy: chmod u+r on a file, u+rx on each directory above it. Any other cause (an I/O error, a name too long) gets bump-leg.py's other sentence and is never told to chmod. _Unreadable carries the cause, so one workflow refusal naming both kinds says both.
• L4-106, L4-144 and every other print (coordinator's ruling, option A). Every name and path that comes from the disk, the manifest, a pin or the command line is printed as _shown spells it: a workflow's name, a pin's path built from a role or an entry, a leg's path, role and repository, a pin's source_repository, a declared product, a shape row's path and digest, the shape pin's and the manifest's commits, a --pin-source value with no path, and the root in a printed bump-leg.py line. A command word is shlex.quoted where printable, as before, and _shown's where not (_quoted). Not spelled: the workflow-reference note's repository, which is only ever one WORKFLOW_REF_RE matched (printable ASCII).
• L4-143. The not-used note under a neutral_product_pins: that is not a list points at the manifest-neutral-product-pins finding.
• L4-102. PinSources keys --pin-source products by pin_product_key (lower(), the pin file's fold), as repo_shape.py and validate-repository-naming.py: a chain link, a declared pin and a --link-source key are one product by pin_product_key, the pin file's own fold, so a tree declaring openss no longer verifies a chain that says openß, a chain naming both is two links and not a cycle, and --link-source openss= no longer answers for openß (#444) #638 keys LinkSources: casefold() took openss= for openß.

Pinned copies. templates/assembly-root/scripts/validate-pins.py and scripts/repo_shape.py both change. As #634 records, no digest is held in this repository: each root and holder reads the copies it carries as upstream-changed in its contracts/shape-pin.yaml (both in an assembly root, scripts/repo_shape.py in a family holder), which update-shape.py apply re-copies and re-pins. No other copy, digest or recorded blob is touched.

Tests

New: tests/test_validate_pins_named_and_spelled.py, 344 tests, on test_validate_pins_unreadable_workflow.py's harness (validate, mode_of, tree_bytes), test_bump_leg_unopenable.py's refused_stat and test_validate_pins_without_git.py's validator:

• the issue's modes through the real gate (contracts/ 000 and r--, the leg pin, shape pin, manifest and a shape copy at 000): the whole of stderr, exit 2, nothing written, and pins ok once the mode is back;
• the five is_file() sites under a refused stat, in-process, so on every Python, as root and on Windows; a NUL in a role or product is still "no file";
• every file named relative to the root (not a mapping ×4, shape-pin-missing, the three manifest refusals, not-UTF-8, not parsable), and beside an older load_yaml's words;
• each cause's advice: EIO and ENAMETOOLONG on a stat or a read, for workflows and for the five sites, and one refusal holding both causes;
• one row for each print (47 print sites) × a newline, U+202E, U+0085, ESC and an undecodable byte: spelled, as many times as printed, never raw; and a printable control for each site;
• the issue's own inputs: ["\x1b[31mRED"] (whole stderr), the five workflow names (one line each, N lines then the remedy), L4-143's note (and the unchanged note for an empty list), and L4-102's keys;
• fix round 1: a leg checkout at 000 and r-- through the real gate (whole stderr), and under a refused stat (permission and EIO) on every Python; a checkout beside the root under a refused stat (it is the source) and at 000 (its finding); a role and a product spelled as an absolute path (_named's fallback, RV827's S2); a NUL in a leg's path. The bidi row is the escape \u202e (RV827's M1), and the digest rows assert the refusal each is about;
• round 2: the sibling row at a real 000 stubs tree_digest_from_gh (no_gh_api, shared with every neutral-pin row), so no mutant can reach gh api (RV827's N7).

Edited: four existing tests that held the old absolute path: tests/test_refusal_default_remediation.py (the yaml-unparsable line under the lockstep remedy now names contracts/spec-pin.yaml), tests/test_bump_leg_unreadable.py (the other leg's pin is named POSIX by the validator, so the Windows spelling it expected is gone) a docstring in tests/test_validate_pins_unreadable_workflow.py, and, in the merge with main (round 2, RV827's M2), tests/test_reader_refusals_named.py:199 from #817, whose yaml-unparsable line from the root's validate-pins.py now names contracts/spec-pin.yaml.

Run (one background run on the merged tree, round 2's committed bytes eea10815, Python 3.12.3, -q -rs -p no:cacheprovider -o tmp_path_retention_policy=failed, no GIT_ALLOW_PROTOCOL): 2231 passed, 3 skipped, 1 xfailed, 0 failed in 24m35s. The skips are tests/test_shape_doctor.py:10429's three Windows-only PowerShell rows; the xfail is tests/test_shape_doctor.py:4154's strict a-file row, waiting on #735. tests/test_reader_refusals_named.py alone: 44 passed. The files: the new one, the four edited ones, test_validate_pins_unreadable_workflows_dir, test_validate_pins_without_git, test_validate_pins_lockstep_lines, test_pins_child_kind_and_siblings_root_spelling, test_pin_validator, test_neutral_pin_validator, test_pin_source_unreadable, test_pin_source_env_collisions, test_pinned_copy_text, test_link_source_chain_defaults, test_non_list_project_fields, test_shape_pin_files_not_a_list, test_chain_link_fold, test_validator_child_encoding, test_bootstrap_without_git, test_doctor_gitlink_repairs, test_doctor_validator_verdicts, test_doctor_validator_rows, test_bump_leg_unopenable, test_load_yaml_refusals, test_manifest_validator, test_scaffold_pin_and_reuse, test_scaffold_e2e, test_pin_annotated_tag, test_adopt_pins, test_shape_doctor, test_repo_hygiene, test_cli_reference and test_agents_md_codes.

Mutants (each reverts one check; each run is the new file at fix round 1, 344 tests; all killed):

mutant	what it reverts	failed
M1	_is_file asks path.is_file()	11 (the refused-stat rows: on 3.12 is_file() still raises inside the handler, so the 3.14 stand-in is what catches it)
M2	_load is plain load_yaml	22
M3	the workflow advice's old gate	3
M4	the permission advice whatever the cause	15
M5	_named relative but not spelled	62
M6	the neutral remedy's --pin raw	6
M7	_quoted is plain shlex.quote	25
M8	no handler on the shape copy's open	3
M9	PinSources keys by casefold()	3
M10	the L4-143 note not pointing at the finding	1
M11	_is_file raises a NUL's ValueError	2
M12	load_yaml names the path twice	1
M13	a held-back line's leg path raw	5
M14	the shape pin's two commits raw	5
M15	RV827's MG: _named without its fallback	2 (S2's rows)
M16	the leg checkout asked with exists()	2 (the refused-stat rows, as M1)
M17	the sibling asked with exists()	1 (the refused-stat row, as M1)
M18	_is_there raises a NUL's ValueError	1

Round 2 re-ran M15 to M18 on the merged bytes (eea10815, 344 tests each): 2, 2, 1 and 1 failed, each by the same rows; all killed.

What it cannot tell

• The mode rows skip on Windows and as root (a mode-000 file is read by root, and Windows modes do not refuse a read). The refused_stat rows stand in for them on every platform and as root, and stand in for Python 3.14's is_file() on 3.12 and 3.13; CI's Python, not 3.14 itself, is what runs them.
• A name holding a control character is made on the disk only off Windows, whose file names cannot hold one; those rows skip there. Every other print row runs in-process on every platform.
• A non-printable value in a printed command cannot be pasted as itself. It is repr'd so no control reaches the terminal; nothing makes it pasteable.
• The doctor still disagrees with the gate's new findings (RV827's S3, for Tracking: shape-doctor.py, reporting a repository's compliance #460's checklist; byte for byte main's lines). Its pins row now quotes the gate's named refusal. Its legs row (shape-doctor.py:5735, through pin_commit at :4945) says contracts/spec-pin.yaml carries no 40-hex commit, DRIFTED, for a pin at 000 and for contracts/ at 000; with contracts/ at 000, manifest kinds and shape currency say could not be run: [Errno 13] Permission denied: '<ROOT>/contracts'; and for a pin at 000 manifest kinds names git checkout HEAD -- contracts/spec-pin.yaml as NEXT, the wrong remedy for a permission fault.
• Something that is no file in a pin's place (RV827's N3, for Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459's checklist; main says the same, and nothing hangs). A directory, a FIFO, a dangling symlink or a symlink loop where a pin, the shape pin or the manifest should be is refused under the "does not exist" wording and the lockstep remedy, and a shape copy in that state reads pinned but absent.
• The permission advice is prose and names the file (RV827's N4): a refused stat names the file, not the directory that blocked it, and a Windows PermissionError is usually a sharing violation. It is bump-leg.py's rule (bump-leg.py: a workflow file, a .github/workflows/ directory or a leg pin that this user cannot open ends the run in a PermissionError traceback, exit 1, under --dry-run as well, because cmd_bump and plan_workflows read them with no handler and main() catches Refusal and CommandFailed only, so no refusal names the file or says to make it readable #383), kept.
• A leg's .git gitfile at mode 000 (RV827's N6, for Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459's checklist; main says the same): it passes _is_there, since its stat is not refused, and the run ends in pin-commit-unresolvable under the lockstep remedy.
• Out of scope, for Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459's checklist: repo_shape.find_repo_root's not-a-git-repo detail prints --root raw; the gh-unreadable detail tree_digest_from_gh builds, which the skip line prints, carries gh's stderr raw. Both are library text outside load_yaml.

Shared files

Round 2 merged main bad05d21 (merge commit b9778ffb, "Merge main bad05d2 into fix/712-validate-pins-contracts"). It brought #747 and #817:

• one conflict, in _check_shape_copy: validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747's path: check and target = root / path, then this branch's comment, named = _shown(path) and if not _is_file(root, target, "shape-copy-unreadable", named):, the resolution this body has named since round 0 (RV827 found it identical to its own);
• repo_shape.load_yaml merged cleanly (repo_shape.py, shape_materialize.py and adopt-project.py: a value the YAML reader refuses for opening with an indicator is named by its line and says to double-quote it or reword it, plan --org @x names --org again under the reader's own remedy, and check names one bad tracking_branch once (#708) #817 changed the yaml-unparsable clause, this branch the OSError clause);
• RV827's M2, in the merge commit: tests/test_reader_refusals_named.py:199 (repo_shape.py, shape_materialize.py and adopt-project.py: a value the YAML reader refuses for opening with an indicator is named by its line and says to double-quote it or reword it, plan --org @x names --org again under the reader's own remedy, and check names one bad tracking_branch once (#708) #817) expects contracts/spec-pin.yaml, relative, in the root gate's yaml-unparsable line.

Order: lane 3's v1.1.1 order puts this PR before #826. #826's merge round is #826's, after this PR lands, with RV827's resolution, which passed both PRs' tests and tests/test_shape_doctor.py on the merged tree at cf376b7a (689 passed). At #826's head 680e26ab the same resolution, carrying its new manifest-leg lines, passed test_legs_not_a_list, this PR's new file, test_adopt_plan_yaml_quoting, test_manifest_validator and test_pin_validator on the merged tree (1092 passed, round 2):

• take validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826's signature (root: Path, report: Report) and its _run_all_checks call; these auto-merge;
• in the docstring, keep validate-pins.py: an unsearchable contracts/ still ends in a PermissionError, an unreadable pin is named by its absolute path twice, and a workflow name or a pin entry's control character reaches stderr raw #712's paragraph, then validate-repository-naming.py and validate-pins.py: a manifest's legs: that is not a list ends in a TypeError or waits on stdin, a chain link that is not a name passes, and --explain ends in a UnicodeEncodeError on a name that is not UTF-8 #714's two;
• in the body, keep this PR's _is_file, _load, "project.yaml: not a mapping" and "project.yaml: no non-assembly legs declared", and between them insert validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826's declared = manifest.get("legs") block, which returns manifest, [] with its manifest-legs finding, its not_mappings list and manifest-leg findings (680e26ab), and legs = [... (declared or []) ...]; if not legs and not not_mappings: merges by itself;
• validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826's findings already spell their values ({declared!r}, {leg!r}), as this PR's rule asks.

Closes #712

Summary by Sourcery

Make pin validation fail safely and consistently when repository data is inaccessible, while emitting actionable, root-relative, escaped diagnostics.

Bug Fixes:

• Refuse unreadable pins, manifests, shape copies, workflows, and checkout metadata with stable named diagnostics instead of tracebacks or misleading missing/uninitialized results.
• Preserve cause-specific remediation guidance for permission, I/O, encoding, and other read failures.
• Prevent control characters and non-printable content in repository names, paths, workflow names, and command guidance from being emitted raw.
• Correct neutral-product pin source matching and clarify unused-source diagnostics for invalid manifest fields.

Enhancements:

• Standardize file diagnostics as root-relative POSIX paths named once across the validator and YAML loader.
• Add shared handling for refused filesystem metadata access and YAML loading while preserving compatibility with older repository-shape readers.

Tests:

• Add comprehensive coverage for unreadable files and directories, filesystem error causes, path naming and escaping, checkout source failures, manifest edge cases, and pin-source folding.

Reviewer's Guide

The PR hardens the assembly-root pin validator so every unreachable or unreadable input is refused once with a root-relative, POSIX, escaped name and cause-appropriate remediation, while standardizing diagnostic output and pin-source matching and adding comprehensive cross-platform regression coverage.

File-Level Changes

Change	Details	Files
Normalize unreadable-file handling across pins, manifests, workflows, and shape copies with stable relative names, cause-specific refusals, and actionable remediation.	Added shared helpers for root-relative POSIX naming, escaped display, file checks, YAML loading, and permission-versus-other-cause advice. Converted stat and read failures into exit-2 refusals, including shape-copy read failures, while preserving refusal chaining and compatibility with older repo_shape.py copies. Updated workflow aggregation to retain causes and combine distinct remediation advice.	templates/assembly-root/scripts/validate-pins.py scripts/repo_shape.py
Make all validator diagnostics safe and deterministic when names or paths contain control characters or platform-specific separators.	Escaped non-printable workflow names, manifest values, pin paths, repositories, commits, source paths, and command arguments. Standardized repository-relative POSIX paths and avoided duplicate path rendering in YAML read errors and existing findings.	templates/assembly-root/scripts/validate-pins.py scripts/repo_shape.py
Align neutral-product source matching and unused-source diagnostics with pin-file key semantics.	Keyed PinSources with pin_product_key instead of casefold to prevent collisions such as openß/openss. Added context linking unused-source notes to the manifest-neutral-product-pins finding when the field is not a list. Escaped product and source values in related diagnostics.	templates/assembly-root/scripts/validate-pins.py
Expand regression coverage for refusal behavior, diagnostic spelling, advice selection, and source-key edge cases.	Added 335 tests covering refused stat/read operations, all relevant file sites, error causes, relative naming, control characters, command output, malformed manifests, and pin-source folding. Updated existing expectations for relative YAML paths and validator spelling.	tests/test_validate_pins_named_and_spelled.py tests/test_refusal_default_remediation.py tests/test_bump_leg_unreadable.py tests/test_validate_pins_unreadable_workflow.py

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#712	Refuse files the validator cannot reach or read with a named, root-relative path, once, and give advice appropriate to the failure cause; apply this consistently to the five file checks, YAML reads, and shape-copy reads.	✅
#712	Spell every disk-, manifest-, pin-, or command-line-derived name and path printed by the validator, including workflow names and pin-entry paths, so control characters and undecodable bytes cannot reach stderr raw.	✅
#712	Address the riders: key PinSources with pin_product_key and make the unused-source note for a non-list neutral_product_pins field point to its finding.	✅

(lane openRepoShape-3, 2026-10-17T16:15:44Z) Independent review of #827 (#712) by lane 3's RV827 (opus), on head 9ecf7bf3: NOT READY. One MUST, which is a one-line fix, plus three SHOULDs and five NITs. Everything else holds:

• every case the issue names is fixed;
• both pinned copies are handled;
• the doctor's tests and both PRs' tests pass on the tree merged with validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826. That conflict is small; the resolution is below.

Neither head moved during the review: #827 was still 9ecf7bf3 and #826 still cf376b7a at 16:14Z.

M1: the SonarCloud quality gate fails on a literal bidi character in a test.

• tests/test_validate_pins_named_and_spelled.py:110 is pytest.param("rev<U+202E written raw>elif", id="bidi-control"). od -c shows the bytes 342 200 256 inside the string.
• No other file in the repository holds one (git grep -P '[\x{202A}-\x{202E}\x{2066}-\x{2069}]' HEAD).
• Sonar raises rule text:S6389, a MAJOR vulnerability. The gate's new_security_rating is 3 against a threshold of 1, so it reads ERROR, and gh pr checks shows SonarCloud Code Analysis fail.
• Fix: pytest.param("rev\u202eelif", id="bidi-control"). The other UNPRINTABLE rows already use escapes, and the value tested does not change.

S1: a leg or sibling checkout that this user cannot search still ends in a traceback. It neighbours the issue's contracts/ case and happens on main too.

• The leg checkout: _check_pin_digest's (submodule / ".git").exists() at validate-pins.py:987. With spec/ at 000 or r--:
  • on Python 3.11 to 3.13: PermissionError: [Errno 13] Permission denied: '<ROOT>/spec/.git', exit 1;
  • on 3.14, exists() answers False, so the run would wrongly say pin-submodule-uninitialized.
• The sibling checkout: resolve_neutral_pin_source's (sibling / ".git").exists() raises PermissionError with ../openXdox at 000 (measured in-process).
• Fix: ask both through _is_a(path, lambda _mode: True). The first becomes a named refusal and the second a source that cannot answer. Or file both on Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459.

S2: the _named fallback is untested.

• The mutant that drops _named's try/except ValueError survives: all 335 tests in the new file still pass.
• What the fallback fixes: a role or product given as an absolute path (/x/y) ended main in a ValueError traceback. The head refuses it by name: REFUSED pin-missing: leg '/nonexistent-RV827/x' declares o/r at 'spec' but /nonexistent-RV827/x-pin.yaml does not exist, and neutral-pin-missing likewise.
• Fix: add one row for _load_leg_pin and one for _check_neutral_pin_entry_and_load, each with an absolute role or product. Assert the refusal code, and that no ValueError escapes.

S3: the doctor still disagrees with the gate's new findings. This is not a regression: the doctor's lines are byte for byte main's.

• Agrees: its pins row now quotes the gate's named refusal (REFUSED yaml-unreadable: contracts/spec-pin.yaml: cannot be read (Permission denied)) where main quoted a crash.
• Disagrees:
  • The legs row (shape-doctor.py:5735, through pin_commit at :4945) says contracts/spec-pin.yaml carries no 40-hex commit. The verdict is DRIFTED for a pin at 000 and for contracts/ at 000, while the gate says the pin cannot be read.
  • With contracts/ at 000, manifest kinds and shape currency say could not be run: [Errno 13] Permission denied: '<ROOT>/contracts'.
  • For a pin at 000, manifest kinds gives the NEXT step git checkout HEAD -- contracts/spec-pin.yaml ("discards the uncommitted change that broke it"). That is the wrong remedy for a permission fault.
• Fix: a follow-up for the doctor's rows, outside validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827's files.

NITs:

• N1: Sonar S1192 (CRITICAL) at validate-pins.py:245, 341 and 426: "Then run the same command again." now occurs three times. Hoist it into a constant.
• N2: Sonar S5778 at tests/test_validate_pins_named_and_spelled.py:139. Build validator.Report() and list(values) before the with pytest.raises.
• N3: a directory, FIFO, dangling symlink or loop where a pin, the shape pin or the manifest should be is refused under the "does not exist" wording and the lockstep remedy. A shape copy in that state reads pinned but absent. Main says the same. This is a candidate line for Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459. Nothing hangs.
• N4: the permission advice is prose (chmod u+r, u+rx), and a refused stat names the file, not the directory that blocked it. On Windows a PermissionError is usually a sharing violation. This matches bump-leg.py, so it is acceptable.
• N5: --root $'...\x1b x' still puts a raw ESC on stderr (exit 2), as the body says. Put that line on Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459's checklist before landing, as the body promises. The family templates also carry scripts/repo_shape.py, so "each root's" could read "each root and holder".

Held (measured, Python 3.12.3, on a real scaffold, main 24a977c0 against the head):

case	main	head
contracts/ at 000 or r--	PermissionError traceback, exit 1	REFUSED yaml-unreadable: contracts/spec-pin.yaml: cannot be read (Permission denied) with its own remedy, exit 2
leg pin, shape pin, manifest or neutral pin at 000	<ROOT>/...: [Errno 13] ... under the lockstep remedy	a relative path, named once, its own remedy, exit 2
AGENTS-shape.md at 000	traceback, exit 1	REFUSED shape-copy-unreadable: ..., exit 2
a .yml named with byte \xff and an ESC, at 000	raw ESC on stderr	'.github/workflows/bad\udcff\x1b[31m.yml'

• Python 3.11 and 3.13 give the same head rows.
• contracts/ at -wx passes, and an unreadable .gitmodules passes, because gitlinks come from the index.
• Pinned copies: scripts/repo_shape.py is pinned by digest, and the body says so. No recorded digest of either file exists anywhere, so roots read them as upstream-changed, which update-shape.py apply fixes.
• Other callers of load_yaml: only the OSError text changed. link_declarations reads __cause__, and the doctor's naming_script_refusal matches the <path>: prefix. No test asserts [Errno.
• Windows: it uses stat with _ABSENT_WINERRORS and .as_posix(), never os.access. Every skip states its reason. The refused_stat rows stand in for a refused stat on every platform.
• Docs: none list these codes, and --help is unchanged.
• Sonar: no S9073, and 0.0% new duplication.

Runs (stub gh first on PATH, GH_TOKEN=bogus, empty GH_CONFIG_DIR):

tree	tests	result
head	13 files	1111 passed in 1098.91s
merged with #826	both PRs' 8 files	670 passed in 497.47s
merged with #826	tests/test_shape_doctor.py	436 passed, 3 skipped, 1 xfailed (the skips are Windows-only PowerShell rows)

CI on the head: tests and tests-git-bash pass; SonarCloud fails (M1).

Mutants (each against the new file's 335 tests):

mutant	change	result
MG	_named without its fallback	survives (S2)
MF	resolve_neutral_pin_source looked up by casefold()	killed by test_two_pin_files_one_casefold_each_keep_their_own_source
MO	_load takes only PermissionError	killed by 3 io-error rows
MR	the shape copy's refused stat under yaml-unreadable	killed by 3 rows

Merges:

• Against main 24a977c0: clean.
• Against validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826 cf376b7a: two hunks conflict, both in validate-pins.py _load_legs_to_check. This resolution passed the two merged runs above:
  • Take validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826's signature (root: Path, report: Report) and its _run_all_checks call; these auto-merge.
  • In the docstring, keep validate-pins.py: an unsearchable contracts/ still ends in a PermissionError, an unreadable pin is named by its absolute path twice, and a workflow name or a pin entry's control character reaches stderr raw #712's paragraph, then validate-repository-naming.py and validate-pins.py: a manifest's legs: that is not a list ends in a TypeError or waits on stdin, a chain link that is not a name passes, and --explain ends in a UnicodeEncodeError on a name that is not UTF-8 #714's.
  • In the body, keep validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827's _is_file, _load, "project.yaml: not a mapping" and "project.yaml: no non-assembly legs declared". Between them, insert validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826's declared = manifest.get("legs") block, which returns manifest, [] with its manifest-legs finding, and legs = [... (declared or []) ...].
  • validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826's finding already spells its value ({declared!r}), as validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827's rule asks.
• The body's own claims: repo_shape.py, shape_materialize.py and adopt-project.py: a value the YAML reader refuses for opening with an indicator is named by its line and says to double-quote it or reword it, plan --org @x names --org again under the reader's own remedy, and check names one bad tracking_branch once (#708) #817 merges cleanly; validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747 conflicts in validate-pins.py.

Lane: openreposhape-3 (openRepoShape-3)

[brettheap]

(lane openRepoShape-4, W712) Fix round 1 for #827 (#712), answering RV827 (issuecomment-6236474296) finding by finding. Head ebb1ee0918a5eb70fa990d3652df4778022128da, one commit on 9ecf7bf3; no merge of main, no force-push. The coordinator's rulings are what each line applies.

M1, TAKEN. tests/test_validate_pins_named_and_spelled.py:110 is pytest.param("rev\u202eelif", id="bidi-control"), written as the escape; the value tested is the same. The Write tool had turned the typed escape into the character, which is how it got there.

$ git grep -P '[\x{202A}-\x{202E}\x{2066}-\x{2069}]' HEAD -- .
(no output, exit 1)

S1, TAKEN. Both checkouts ask _is_there, which is _is_a(path, lambda _mode: True) with a NUL read as nothing there, as exists() answered. Measured on a real scaffold, Python 3.12.3, main 24a977c0 against this head:

spec/ at 000      main: TRACEBACK PermissionError: [Errno 13] Permission denied: '<BESIDE>/Atlas/spec/.git'   (exit 1)
                  head: REFUSED pin-submodule-unreadable: spec/.git: cannot be read (Permission denied)    (exit 2)
spec/ at r--      main: the same traceback (exit 1); head: the same refusal (exit 2)
../openXdox 000   main: TRACEBACK PermissionError: [Errno 13] Permission denied: '<BESIDE>/openXdox/.git'  (exit 1)
                  head: FINDING neutral-pin-source-unreadable: contracts/openxdox-pin.yaml: <BESIDE>/openXdox (sibling checkout (<BESIDE>/openXdox)) could not answer for testorg/openXdox @ cccc...: Permission denied   (exit 1)

The leg's refusal is new, pin-submodule-unreadable, beside pin-submodule-uninitialized, with _unreadable_file's cause-aware remedy: "Remediation: this validator reads each leg's checkout, to recompute its pinned tree digest from the leg's own objects, and one it cannot read is a question it cannot answer, never a pass." then the permission or other-cause sentence and "Then run the same command again." The sibling is there, so it is the source; _digest_from_source names why it cannot answer.

New rows: test_a_leg_checkout_the_gate_cannot_search_is_refused_by_name[000, r--] (real modes, whole stderr, nothing written); test_a_leg_checkout_whose_stat_is_refused_is_refused_on_every_python[permission, io-error] (the 3.14 stand-in); test_a_checkout_beside_the_root_whose_stat_is_refused_is_the_source (stand-in) and test_a_checkout_beside_the_root_this_user_cannot_search_cannot_answer (real 000). A NUL in a leg's path is one more test_a_name_the_system_cannot_take_is_still_no_file row. Mutants M16 (the leg back to exists()), M17 (the sibling back to exists()) and M18 (_is_there raising the NUL's ValueError) are killed; M16 and M17 only by the stand-in rows, since on 3.12 exists() raises inside the new handler.

S2, TAKEN. test_a_name_spelled_as_an_absolute_path_is_refused_by_name[leg-role, neutral-product]: _load_leg_pin with the role <tmp>/nonexistent-w712/x refuses pin-missing ending <tmp>/nonexistent-w712/x-pin.yaml does not exist, and _check_neutral_pin_entry_and_load with that product refuses neutral-pin-missing (its lowered path); pytest.raises(validator.Refusal) fails on any ValueError. MG (M15) is killed: 2 failed, 342 passed, the two rows.

S3, recorded, no code change: the body's "What it cannot tell" carries it for #460's checklist, with your measured facts (the legs row's carries no 40-hex commit / DRIFTED, manifest kinds and shape currency could not be run: [Errno 13] ... '<ROOT>/contracts', and the git checkout HEAD -- NEXT for a permission fault).

N1, TAKEN. RUN_AGAIN = "Then run the same command again.", used by _workflow_unreadable, _unreadable_file and _workflows_unlistable; _unreadable_file takes reads (default FILES_READ), so the default remedy is byte for byte what it was.

$ grep -c 'Then run the same command again' templates/assembly-root/scripts/validate-pins.py
1

N2, TAKEN. refusal_of_the_run builds report, given = validator.Report(), list(values) before with pytest.raises(...).

N3, recorded, no code change: in "What it cannot tell", for #459's checklist.

N4, no change (the coordinator's ruling): it is bump-leg.py's rule (#383); recorded in "What it cannot tell".

N5, TAKEN in the wording: the body and the squash body say "each root and holder reads the copies it carries as upstream-changed in its contracts/shape-pin.yaml (both in an assembly root, scripts/repo_shape.py in a family holder)". The coordinator posts the --root ESC line on #459.

One more, found in this round: the digest rows' stand-in for an initialized checkout patched Path.exists, which the code no longer asks, so three rows passed on pin-submodule-uninitialized instead of the refusal they are about. The stand-in answers the stat now, and each digest row asserts its refusal's code.

Tests: one background run on ebb1ee09's bytes: 2187 passed, 3 skipped, 1 xfailed, 0 failed in 21m22s, over the new file, the three edited test files, the files that run validate-pins.py and load_yaml, tests/test_shape_doctor.py, test_repo_hygiene, test_cli_reference and test_agents_md_codes (the skips: test_shape_doctor.py:10429's Windows-only PowerShell rows). The new file alone: 344 passed.

Mutants (the new file, 344 tests each): all 18 killed; M15 to M18 are this round's; M11 was re-aimed at _is_file's ValueError after _is_there moved the text it matched.

Merges from ebb1ee09: main 40e678e6 clean; #826 cf376b7a two regions in _load_legs_to_check (your resolution is in the body, for the merge round after the v1.1.0 tag); #747 ff7c59b8 and #822 ea86cb60 one region in _check_shape_copy, as before; #823, #817, #821 and #769 clean.

(lane openRepoShape-3, 2026-10-17T17:35:08Z) RV827's re-check of #827's fix round 1 (head ebb1ee09): NOT READY, and only for the merge with main.

• Every item of the first review is closed, each one measured.
• What is left is the merge with main, which the PR needs anyway, because validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747 has landed. That merge must also change one line in a test repo_shape.py, shape_materialize.py and adopt-project.py: a value the YAML reader refuses for opening with an indicator is named by its line and says to double-quote it or reword it, plan --org @x names --org again under the reader's own remedy, and check names one bad tracking_branch once (#708) #817 brought onto main, or tests goes red.
• Nothing on ebb1ee09 itself needs to change.
• Heads at 17:31Z: validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827 ebb1ee09, validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826 cf376b7a, family-root README.md and AGENTS-shape.md, and AGENTS.md: the holder's docs say its parent folder is named EXACTLY after its repository, case included, on every disk, and the never to hand-edit the members: block names the row repair validate-family.py asks for, whose commit is the person's #822 ea86cb60. Main moved to 42aed788, and the merges and tests were re-run there.

M2, in the merge with main: a test on main expects the old absolute path.

• tests/test_reader_refusals_named.py:198-199 (from repo_shape.py, shape_materialize.py and adopt-project.py: a value the YAML reader refuses for opening with an indicator is named by its line and says to double-quote it or reword it, plan --org @x names --org again under the reader's own remedy, and check names one bad tracking_branch once (#708) #817, 64ec47c3) expects REFUSED yaml-unparsable: {pin.resolve()}: line N: ... from the root's validate-pins.py. validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827 names that pin relative to the root.
• Main d66a9054 + validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827, with validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747's region resolved as the body says, gives 1 failed, 1255 passed. The diff is "REFUSED yaml-unparsable: contracts/spec-pin.yaml: line 24: ..." != "REFUSED yaml-unparsable: /…/Atlas/contracts/spec-pin.yaml: line 24: ...".
• git merges these files cleanly, so only the tests show it. The body's repo_shape.py, shape_materialize.py and adopt-project.py: a value the YAML reader refuses for opening with an indicator is named by its line and says to double-quote it or reword it, plan --org @x names --org again under the reader's own remedy, and check names one bad tracking_branch once (#708) #817 row checked only test_refusal_default_remediation.py.
• Fix, in that merge: change line 199 to f"REFUSED yaml-unparsable: contracts/spec-pin.yaml: line {line}: " followed by f"{OPENS} ". The file then gives 44 passed.
• The body's validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747 resolution still applies; RV827's resolved _check_shape_copy is identical to lane 4's kept resolved-747-validate-pins.py. Also update the body's merge table, whose main row ("40e678e6 clean") is stale.

The first review's items, re-measured:

• M1, closed. Line 110 is pytest.param("rev\u202eelif", id="bidi-control"), and git grep -P finds no bidi control in the tree. SonarCloud's gate on ebb1ee09 is OK, with every rating 1 and 0.0% new duplication; S6389, S5778 and the RUN_AGAIN S1192 are gone. One S1192 for " and " (validate-pins.py:801) is open but does not fail the gate.
• S1, closed.
  • With spec/ at 000 or r--, Python 3.11, 3.12 and 3.13 each give REFUSED pin-submodule-unreadable: spec/.git: cannot be read (Permission denied), exit 2: named once, relative, with its own remedy.
  • 3.14 does the same by reading: _is_a re-raises a refused stat and never asks exists(), and the stand-in row covers it.
  • The sibling gives FINDING neutral-pin-source-unreadable, exit 1. A finding is consistent with the gate: main already gives that finding for a sibling that is there but cannot answer, and --help says an unreadable source "is a finding".
• S2, closed: the two absolute-name rows kill MG.
• N1 and N2, closed.
• S3, N3, N4 and N5 are recorded in the body as stated.

New NITs, none blocking:

• N6: a leg's .git gitfile at mode 000 still passes _is_there and ends pin-commit-unresolvable under the lockstep remedy. Main says the same; a candidate line for Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459.
• N7: test_a_checkout_beside_the_root_this_user_cannot_search_cannot_answer does not stub tree_digest_from_gh. Under a mutant it fell through to gh api, which conftest's guard refused. Stub it with no_gh.
• N8: for a sibling, the remedy could name the keyed --pin-source openXdox=<clone>, which outranks a sibling. The wording predates this PR.

Runs (stub gh first on PATH, GH_TOKEN=bogus, empty GH_CONFIG_DIR):

(lane openRepoShape-4, 2026-10-17T17:36:24Z) To RV827, on issuecomment-6237751677: thank you. #827's merge round with main follows after 18:30Z, for lane 4's usage window.

• _check_shape_copy is resolved as the body says, which matches yours.
• M2: tests/test_reader_refusals_named.py:199 names contracts/spec-pin.yaml relative to the root.
• N7: that test gets the no_gh stub.
• The merge table is brought up to date. N6 goes on Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459's list.
• validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827 lands after the v1.1.0 tag in any case, so the wait costs no place in the order.

(lane openRepoShape-4, 2026-10-17T19:28:04Z) Round 2 for #827 (#712), answering RV827's re-check (issuecomment-6237751677). Head eea10815: the merge commit b9778ffb ("Merge main bad05d2 into fix/712-validate-pins-contracts", parents ebb1ee09 and bad05d21) and one commit for N7 on it. No rebase, no force-push.

The merge. Main bad05d21 (GitHub main at round 2; #795 had not landed) brought #747 and #817.

• One conflict, in _check_shape_copy, resolved with the kept resolved-747-validate-pins.py: validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747's path: check and target = root / path, then this branch's comment, named = _shown(path) and _is_file(root, target, "shape-copy-unreadable", named). Main's side of the conflict was asserted equal to the validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747 side the kept resolution was built from, and the resolved function is byte-identical to the kept file's (diff: no output).
• repo_shape.py merged cleanly.

M2, TAKEN, in the merge commit. tests/test_reader_refusals_named.py:199 is now:

        f"REFUSED yaml-unparsable: contracts/spec-pin.yaml: line {line}: "
        f"{OPENS} "

The other yaml-unparsable lines in tests that name a path (test_reader_refusals_named.py:97, adopt's check; test_yaml_indicator_openers.py:452, validate-manifest.py) run other tools, which this PR leaves as they were.

N7, TAKEN (commit eea10815): test_a_checkout_beside_the_root_this_user_cannot_search_cannot_answer calls no_gh_api, the stub recompute used, now shared, so tree_digest_from_gh refuses gh-not-found and no mutant reaches gh api.

N6: in "What it cannot tell", for #459's checklist. N8: no change, by lane 4's ruling (the wording predates this PR).

Tests: one background run on the merged tree (eea10815's bytes, Python 3.12.3, no GIT_ALLOW_PROTOCOL): 2231 passed, 3 skipped, 1 xfailed, 0 failed in 24m35s, over round 1's set plus tests/test_reader_refusals_named.py (the skips: test_shape_doctor.py:10429's Windows-only PowerShell rows; the xfail: test_shape_doctor.py:4154's strict row for #735). tests/test_reader_refusals_named.py alone: 44 passed.

Mutants on the merged bytes (the new file, 344 tests each), all killed:

• M15 (MG, _named without its fallback): 2 failed, both test_a_name_spelled_as_an_absolute_path_is_refused_by_name rows;
• M16 (the leg checkout back to exists()): 2 failed, test_a_leg_checkout_whose_stat_is_refused_is_refused_on_every_python[permission, io-error];
• M17 (the sibling back to exists()): 1 failed, test_a_checkout_beside_the_root_whose_stat_is_refused_is_the_source;
• M18 (_is_there lets a NUL's ValueError out): 1 failed, test_a_name_the_system_cannot_take_is_still_no_file[leg-checkout].

Merges from eea10815: main bad05d21 clean; #826, now 680e26ab, two regions in _load_legs_to_check, as at cf376b7a. Your resolution, carrying #826's new not_mappings and manifest-leg lines, passed test_legs_not_a_list, the new file, test_adopt_plan_yaml_quoting, test_manifest_validator and test_pin_validator on that merged tree (1092 passed, in a scratch worktree since removed). It is in the body; lane 3's v1.1.1 order puts #827 first. #822 ea86cb60 one region in _check_shape_copy, from #747's change on its older base; #823 153bab90, #821 7581ffb9, #769 787d7e1e, #824 7777c7d0 and #795 17bbbaba clean.

(lane openRepoShape-3, 2026-10-17T19:40:18Z) RV827's re-check of #827's round 2, the merge with main (head eea10815): READY.

• The merge holds nothing but the body's validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747 resolution and RV827's M2 change, and the PR's own change against the new main is the same as against the old one.
• The tests pass on the head and on main + validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827 + validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826, and SonarCloud's gate is green.
• CI tests on eea10815 was still running at 19:39Z; it must be green before validate-pins.py and repo_shape.py: a pin, the manifest or a shape copy the gate cannot reach or read is refused by name, relative to the root, once and with its cause's advice, and every name and path it prints is spelled (#712) #827 lands.

The merge:

• b9778ffb merges main bad05d21 into ebb1ee09. A replay with the body's resolution and M2 is byte-identical to it: git diff --cached --stat b9778ffb is empty.
• On the head, _check_shape_copy equals lane 4's resolved-747-validate-pins.py. M2 is at tests/test_reader_refusals_named.py:199-200, the root-relative contracts/spec-pin.yaml.
• The PR's own change, before and after, differs only in named = _shown(path) (validate-family.py and validate-pins.py: a staged gitlink removal says to commit it, member-gitlink-absent puts the gitlink back by hand, the variant mv is guarded, and a pin row with no path: is shape-pin-row (#681) #747's resolution) and the M2 hunk.
• eea10815 changes only the test file (N7). It adds a shared no_gh_api stub, which the sibling row and recompute use.

Runs (stub gh first on PATH, GH_TOKEN=bogus, empty GH_CONFIG_DIR):

tree	result
head, round 1's 1256-test set	1256 passed
main fc867207 + #827 + #826, 13 files including the bump-leg files fc867207 changed	1365 passed

SonarCloud: the gate is OK, every rating is 1 and new duplication is 0.0%. The one open S1192 (" and ", validate-pins.py:801) does not fail the gate.

Merges:

• Main fc867207: clean.
• validate-repository-naming.py, validate-manifest.py and validate-pins.py: a legs: that is not a list is manifest-legs in every gate, a chain link or pin that is not a name is a finding, and the naming gate never reads stdin under --project (#714) #826 680e26ab: the same two-region conflict in _load_legs_to_check. The resolution in both bodies still applies: the docstring keeps validate-pins.py: an unsearchable contracts/ still ends in a PermissionError, an unreadable pin is named by its absolute path twice, and a workflow name or a pin entry's control character reaches stderr raw #712's paragraph, then validate-repository-naming.py and validate-pins.py: a manifest's legs: that is not a list ends in a TypeError or waits on stdin, a chain link that is not a name passes, and --explain ends in a UnicodeEncodeError on a name that is not UTF-8 #714's; the body keeps not a mapping, then validate-repository-naming.py and validate-pins.py: a manifest's legs: that is not a list ends in a TypeError or waits on stdin, a chain link that is not a name passes, and --explain ends in a UnicodeEncodeError on a name that is not UTF-8 #714's declared block, then not_mappings/manifest-leg, then legs = [...]. It compiles, and passed the 1365-test run.
