Lane: openreposhape-4 (openRepoShape-4)
Claim: #714 (comment)

What changed and why

Milestone v1.1.1: a DRAFT that lands after the v1.1.0 tag. The issue lists #634, #661 (#744) and #702 to land first, and all three are on main. #712's #827 changed validate-pins.py too and has landed (9f235da2); this branch merges it (see Shared files). This PR leaves its function, _check_neutral_pin_entry_and_load, alone.

L4-141: a legs: that is not a list.

• Before. The naming gate (_project_leg_chains, _targets_from_project) and validate-pins.py (_load_legs_to_check) iterated value or []:
  • legs: 5 ended both in TypeError: 'int' object is not iterable, exit 1.
  • legs: openXdox was walked one character at a time. The naming gate found no target and read names from stdin. With stdin /dev/null it refused naming-no-target, exit 2; with a pipe left open it waited until killed. validate-pins.py refused manifest-no-legs with the lockstep remedy (git submodule update ...).
  • validate-manifest.py said legs is missing or empty for 5, which is false.
• Now. The three gates say one true sentence, exit 1:

  FINDING manifest-legs: legs is 5, expected a list of `role:`, `repository:` and `path:` mappings
  

  • 0, false and '' are not a list, as validate-repository-naming.py (_pins_from_project :302, _chain_from_leg :318), validate-manifest.py (_declared_pins :85) and validate-pins.py (PinSources :390, called at :698) iterate the project's own neutral_product_pins: and a leg's naming.referent_chain: without asking they are lists, so 5 (or true, 1.5) in either field ends the naming gate in TypeError: 'int' object is not iterable, exit 1, neutral_product_pins: 5 ends the other two validators the same way before validate-manifest.py reaches the manifest-neutral-product-pins finding it has for it, and make validate stops in a traceback at its first command; a scalar openXdox in neutral_product_pins: is read as the characters X, d, e, n, o, p, x by the naming gate, which classifies and exits 0 #443 reads neutral_product_pins:.
  • validate-manifest.py keeps legs is missing or empty for absent, null and [], and the naming gate now says it too under --project (below).
  • In validate-pins.py, a non-list legs: is this finding and not the manifest-no-legs refusal. The shape pin and the neutral-product pins are still checked. A refusal one of them makes (for example neutral-pin-missing) is printed alone, as every refusal of this gate is, so the finding is not printed then.
  • Absent, null and [] are still REFUSED manifest-no-legs, exit 2, in validate-pins.py (lane 4's ruling on RV826's S2), and rows pin it.
• No stdin under --project (lane 4's ruling). Under --project the naming gate never reads stdin, whatever legs: holds, so absent, null, [] and [5] cannot wait either.
  • A finding with no name to classify is now said, exit 1, where naming-no-target used to drop it.
  • A manifest that names no leg (legs: absent, null or []) is now FINDING manifest-legs: legs is missing or empty, exit 1, as validate-manifest.py says (lane 4's ruling). It was REFUSED naming-no-target: no names given. Pass names, `--project project.yaml`, or names on stdin., exit 2, which offered --project and stdin to a run that had passed --project. Under --project, a run with no target now always has a finding.
  • Without --project, naming-no-target is unchanged.
• A legs: entry that is not a mapping ([5], [openXdox], [[a]], [null]; RV826's S3).
  • Before: three answers. The naming gate said a leg has no `repository:` , which is untrue of 5. validate-manifest.py said manifest-leg: a leg is not a mapping: 5. validate-pins.py refused manifest-no-legs with the git submodule update remedy.
  • Now: each gate says FINDING manifest-leg: a leg is not a mapping: 5, exit 1. validate-pins.py chooses manifest-no-legs only where no entry was one.
  • A mapping with no repository: still says FINDING project.yaml: a leg has no `repository:` . It now names the manifest relative to the project root, through _shown, where the --project path was printed raw, as given.

L4-142: a chain link or a declared pin that is not a name.

• Before. Both were read with str():
  • [5] was the pin or the link '5'.
  • referent_chain: "\x1b[31mRED" exited 0 in the naming gate and in validate-manifest.py, and --explain printed CHAIN <ESC>[31mRED raw.
• The rule. _not_a_name is one rule, written in both files with the same words:
  • the entry is text (the type neutral-pin-entry-malformed asks for);
  • it is not blank;
  • it is printable by str.isprintable (_shown's rule).
• What each reader does. A pin entry that is not a name declares nothing, and the other entries still do. A chain holding such a link records no chain, as one that is not a list records none. Dropping only that link would ask about a chain nobody recorded.
• What is said. Each such entry is a finding under its field's existing code. The entry is spelled with repr, which is what _shown gives any entry the printability rule refuses:

  FINDING naming-referent-chain: leg 'assembly': referent_chain link '\x1b[31mRED' is not a neutral-product name: it holds a character that is not printable
  FINDING manifest-neutral-product-pins: neutral_product_pins entry 5 is not a neutral product name: it is not text
  FINDING manifest-neutral-product-pins: neutral_product_pins entry '' is not a neutral product name: it is blank
  

• What stays. A blank string chain ('', ' ') is still the empty record: no chain and no finding, as validate-repository-naming.py (_pins_from_project :302, _chain_from_leg :318), validate-manifest.py (_declared_pins :85) and validate-pins.py (PinSources :390, called at :698) iterate the project's own neutral_product_pins: and a leg's naming.referent_chain: without asking they are lists, so 5 (or true, 1.5) in either field ends the naming gate in TypeError: 'int' object is not iterable, exit 1, neutral_product_pins: 5 ends the other two validators the same way before validate-manifest.py reaches the manifest-neutral-product-pins finding it has for it, and make validate stops in a traceback at its first command; a scalar openXdox in neutral_product_pins: is read as the characters X, d, e, n, o, p, x by the naming gate, which classifies and exits 0 #443 pins it.
• Tightened (RV826's N5). A list chain with a blank link, [openXdox, ''], recorded ('openXdox',), exit 0. Its blank link is now it is blank, exit 1, and the chain records nothing.

L4-02: a name that is not UTF-8.

• stdout. The naming gate turns a strict or surrogateescape stdout into backslashreplace, as validate-pins.py's _emit_report does. --explain and the plain listing no longer end in a UnicodeEncodeError under PYTHONIOENCODING=utf-8.
• stdin. A strict stdin is read with surrogateescape, as argv is. Atl\xffas on stdin is Atl\udcffas and reaches FINDING naming-unclassified: Atl\udcffas, where it was a UnicodeDecodeError.

Riders.

• L4-145, taken. A test pins the chain sentence before the same leg's declared-role finding (validate-repository-naming.py (_pins_from_project :302, _chain_from_leg :318), validate-manifest.py (_declared_pins :85) and validate-pins.py (PinSources :390, called at :698) iterate the project's own neutral_product_pins: and a leg's naming.referent_chain: without asking they are lists, so 5 (or true, 1.5) in either field ends the naming gate in TypeError: 'int' object is not iterable, exit 1, neutral_product_pins: 5 ends the other two validators the same way before validate-manifest.py reaches the manifest-neutral-product-pins finding it has for it, and make validate stops in a traceback at its first command; a scalar openXdox in neutral_product_pins: is read as the characters X, d, e, n, o, p, x by the naming gate, which classifies and exits 0 #443's M6b).
• Not taken: L4-146 (repo_shape.py's pin_source_env_shared per chain) and L4-147 (scaffold-project.py records a Kelvin sign as typed). This change does not cover either.

Adoption (RV826's M1). adopt-project.py asks the project's own validate-manifest.py about the manifest it would write.

• So a --pin null, True or 007 written bare (bare_pins, as before adopt-project.py: execute writes each neutral_product_pins: entry bare, so plan --pin 007@<commit> says adoption verified over a root whose own validate-pins.py refuses entry 7 #514) is now that validator's it is not text, not adopt-project.py plan writes null, true and other YAML keywords unquoted, so plan --spec-path null silently mounts the leg at the default spec #181's misread.
• RV826's patch moves those rows of tests/test_adopt_plan_yaml_quoting.py out of REFUSED into PINS_NOT_TEXT, which covers plan, check and execute, and REFUSED's comment says so.
• No shipped template writes a bare pin since adopt-project.py: execute writes each neutral_product_pins: entry bare, so plan --pin 007@<commit> says adoption verified over a root whose own validate-pins.py refuses entry 7 #514.

Pinned copies (RV826's N4). The three scripts are pinned shape copies:

• validate-repository-naming.py is in shape_materialize.COPIED_FROM_SHAPE, so the issue's "(not pinned)" is wrong;
• validate-pins.py and validate-manifest.py are in COPIED_VERBATIM.

No digest of them lives in this repository, so nothing is re-pinned here. In a project, update-shape.py check reports each as upstream-changed, and apply re-copies and re-pins them.

Tests

tests/test_legs_not_a_list.py is new and has 112 tests. It builds on tests/test_non_list_project_fields.py's harness (#443) and covers:

• the legs sentence in all three gates, for the 8 values that are not a list;
• the naming gate with stdin a pipe that is open and never written, under a 30 s bound, for openXdox, 5, {a: b}, absent, null, [] and [5]: each finishes with exit 1 and its finding (legs is missing or empty for absent, null and []);
• legs is missing or empty from the naming and manifest gates alike;
• naming-no-target, in its own words, still refused without --project;
• names on stdin: read without --project, never with it;
• validate-pins.py still checking the shape pin and the neutral pins past legs: 5;
• validate-pins.py still refusing manifest-no-legs, exit 2, for absent, null and [] (S2);
• manifest-leg: a leg is not a mapping for [5], [openXdox], [[a]] and [null] in all three gates, and for both entries of [5, openXdox], each once (RV826's NIT 1); and a mapping with no repository: naming the manifest relative and spelled (S3);
• each gate's order of the two field sentences, as it is (N1);
• the _not_a_name readers, word for word in both files;
• each chain-link and pin-entry case, in both gates, with no raw ESC;
• the controls ([openß], a blank string);
• the L4-145 order;
• L4-02 on a strict stdout (--explain and the plain listing), on a surrogateescape stdout read as bytes (S1), and on a strict stdin.

tests/test_adopt_plan_yaml_quoting.py gets RV826's M1 rows (PINS_NOT_TEXT).

Targeted run at the first commit 8dbf3e5c: 2420 passed, 4 skipped, 1 xfailed in 923.59s, exit 0. The run covered the new file, the files that run the three gates or read their output (36 files in all, with test_shape_doctor.py), and test_repo_hygiene.py, test_cli_reference.py and test_agents_md_codes.py. The skips are platform-only: test_bump_leg.py:693 (a disk that ignores case) and test_shape_doctor.py:10429 x3 (PowerShell, Windows only).

Run after the ruling's commit cf376b7a, which changes only the naming gate: 886 passed in 140.20s, exit 0, with no skips. It covered the new file, the naming-gate files (test_naming_policy, test_non_list_project_fields, test_chain_link_fold, test_chain_remedy_callers, test_link_source_chain_defaults, test_scaffold_referent_chain_links, test_doctor_validator_verdicts, test_doctor_validator_rows, test_validator_child_encoding and test_pinned_copy_text), and test_repo_hygiene, test_cli_reference and test_agents_md_codes.

Run on the final bytes (fix round 1, head 680e26ab): 1767 passed, 3 skipped, 1 xfailed in 1038.26s, exit 0. It covered RV826's 8 files (test_legs_not_a_list, test_manifest_validator, test_naming_policy, test_validator_child_encoding, test_doctor_validator_verdicts, test_chain_link_fold, test_cli_reference and test_agents_md_codes), test_adopt_plan_yaml_quoting.py (518 tests, all passed), test_shape_doctor.py, test_scaffold_leg_path_collisions.py and test_repo_hygiene.py. The skips are test_shape_doctor.py:10429 x3 (PowerShell, Windows only).

Run on the merge round's bytes (head 124bbd7b: the merge of main 9f235da2 and the NIT 1 row): 5415 passed, 4 skipped, 1 xfailed in 4943.86s, exit 0. It covered 70 files:

• 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 own files;
• the files 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 gated (test_validate_pins_named_and_spelled, test_bump_leg_unreadable, test_refusal_default_remediation, test_validate_pins_unreadable_workflow, test_reader_refusals_named, test_pin_validator, test_manifest_validator);
• test_repo_hygiene, test_cli_reference and test_agents_md_codes;
• every test file git grep -l finds naming validate-pins.py or validate-repository-naming.py.

The skips are platform-only: test_bump_leg.py:697 (a disk that ignores case) and test_shape_doctor.py:10429 x3 (PowerShell, Windows only).

What it cannot tell

• Windows. CI is Linux only, and the argv half of L4-02 is skipped on Windows: a command line there holds no byte that is not UTF-8. The stdin half runs on every platform.
• The default stdout now prints the escape. Under the default C.UTF-8 locale, stdout is surrogateescape, and the plain listing used to print the raw byte. Following _emit_report, it now prints Atl\udcffas, the spelling stderr's naming-unclassified already used.
• validate-pins.py still reads a pin entry holding ESC as a pin. It prints neutral-pin-missing with the ESC raw in the pin path. That is L4-144, 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. make validate now stops at the naming gate's finding first.
• ' ' as a pin entry. validate-pins.py still treats a whitespace-only entry as a pin and refuses it neutral-pin-missing. The other two gates now say it is blank. Every gate fails it.
• A manifest that names no leg, in validate-pins.py (for Tracking: shape-doctor.py, reporting a repository's compliance #460's checklist). It is still REFUSED manifest-no-legs, exit 2, where the other two gates say legs is missing or empty, exit 1. Its remedy, git submodule update --init --recursive, cannot add a leg. It is kept because 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 rewrites the same function.
• validate-manifest.py stops at legs: (RV826's N1). With legs: [] and neutral_product_pins: [5] it gives one finding where the naming gate gives two. The rows pin each gate's order as it is.
• The other readers of legs: (RV826's S4: shape-doctor.py:1182, templates/assembly-root/scripts/bootstrap.py:1111, scripts/bump-leg.py:205 and update-shape.py:2504, at the merge head) still iterate legs or []. Filed as shape-doctor.py, bootstrap.py, bump-leg.py and update-shape.py: a manifest's legs: that is not a list ends in a TypeError, or reads as a project with no legs, where #714 makes the three gates report manifest-legs #832.

Shared files

The merge round. #827 (#712) landed on main as 9f235da2. This branch merges it as a merge commit, 07412007 (parents 680e26ab and 9f235da2), with no rebase or force-push. Only templates/assembly-root/scripts/validate-pins.py conflicted, in _load_legs_to_check; tests/test_adopt_plan_yaml_quoting.py merged on its own. The resolution follows RV826's layout (#826 issuecomment-6240291087), run with a copy of its resolve_827_r1.py:

• Hunk 1, the docstring: 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, a blank line, 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 paragraphs.
• Hunk 2, the body: 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 raise Refusal("manifest-unreadable", "project.yaml: not a mapping"), then this branch's lines after its own raise: the declared read with its manifest-legs finding, the not_mappings loop with its manifest-leg findings, and the legs line.
• Git merged the rest itself: if not legs and not not_mappings: with 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 relative project.yaml: no non-assembly legs declared.
• Compared with RV826's: the resolved _load_legs_to_check is identical, as text, to RV826's pair resolution in both merge orders (r1pairA, r1pairB). The whole validate-pins.py is byte-identical to its landing tree's (RV826-land).

• Every merge is clean. shape-doctor.py, bootstrap.py, bump-leg.py and update-shape.py: a legs: that is not a list, or holds an entry that is not a mapping, is said in #714's words, so the doctor's leg rows wait on the manifest row instead of calling the project one with no legs, bootstrap places no leg for it, and bump-leg.py and update-shape.py refuse it by name where each ended in a TypeError (#832) #862 (lane 4's shape-doctor.py, bootstrap.py, bump-leg.py and update-shape.py: a manifest's legs: that is not a list ends in a TypeError, or reads as a project with no legs, where #714 makes the three gates report manifest-legs #832) lands after this one.
• bootstrap.py: step (a) decodes git's output as the system decodes a name it is given, so a branch whose upstream is not UTF-8 is moved back, and a good branch this system's encoding cannot write gets a line of its own, not a traceback (#710) #824's head moved from 7777c7d0 to 89ef951c by a merge of main; both give tree 911dbcd9.

Closes #714

Summary by Sourcery

Make repository validation consistently report malformed manifest structures and names while avoiding project-mode stdin hangs and encoding failures.

New Features:

• Report malformed legs: values and non-mapping leg entries consistently across the naming, manifest, and pin validation gates.
• Validate neutral-product pins and referent-chain links as printable, non-blank text names and report malformed entries without discarding valid entries.
• Prevent project-based naming validation from reading stdin when no targets are present.
• Handle non-UTF-8 names safely on validator stdin and stdout.

Bug Fixes:

• Replace crashes, incorrect refusals, misleading diagnostics, and potential stdin hangs caused by malformed manifest structures.
• Ensure malformed bare pins generated during adoption are reported by the project's manifest validator.

Enhancements:

• Align findings, ordering, and path formatting across the validation gates for malformed manifest fields.

Tests:

• Add comprehensive coverage for malformed legs, invalid chain links and pins, stdin behavior, encoding failures, diagnostic ordering, and adoption validation.

[sourcery-ai]

Reviewer's Guide

The PR makes malformed legs: data consistently produce actionable findings across all gates, prevents project-mode stdin hangs, rejects non-name chain links and pin entries consistently, hardens naming output/input against invalid UTF-8, and adds extensive regression coverage.

File-Level Changes

Change	Details	Files
Standardize handling of malformed or empty legs: values across all validation gates.	Added a shared-style manifest-legs finding for non-list values instead of iteration errors or incorrect refusals. Preserved the legs is missing or empty finding for absent, null, and empty-list manifests. Made the naming gate avoid stdin entirely when --project is supplied and report project findings even when no target is available. Changed pin validation so malformed legs: remains a finding while shape and neutral-pin checks continue.	scripts/validate-repository-naming.py templates/assembly-root/scripts/validate-manifest.py templates/assembly-root/scripts/validate-pins.py
Validate chain links and neutral-product pin entries as printable, nonblank text names.	Added matching _not_a_name rules to the naming and manifest validators. Report malformed entries with field-specific findings and reasons while retaining valid entries. Treat a chain containing any invalid link as recording no chain, while preserving blank-string chain semantics. Added coverage for non-text, blank, non-printable, Unicode, and mixed-validity entries.	scripts/validate-repository-naming.py templates/assembly-root/scripts/validate-manifest.py tests/test_legs_not_a_list.py
Make naming-gate input and output robust for non-UTF-8 names.	Read strict stdin with surrogateescape so invalid bytes reach normal classification. Reconfigure strict or surrogateescape stdout to backslashreplace for explain and plain-listing output. Added regression coverage for invalid UTF-8 on stdin, argv, explain output, and normal listings.	scripts/validate-repository-naming.py tests/test_legs_not_a_list.py
Add comprehensive regression and mutation-oriented coverage for the new validation behavior.	Added an 88-test suite covering all three gates, open-stdin hangs, finding order, retained checks, refusal behavior, and cross-validator wording. Verified valid printable names and legacy blank-chain behavior remain unchanged.	tests/test_legs_not_a_list.py

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#714	Treat a project manifest's legs: value that is not a list as a manifest-legs finding in the naming gate and validate-pins.py, without raising a TypeError, iterating its characters, or waiting on stdin; preserve the expected missing-or-empty finding for absent, null, or empty lists.	✅
#714	Report chain links and declared pins that are not valid names as findings in the naming and manifest validators, and pin the naming gate's chain-finding order with the requested test.	✅
#714	Make the naming gate handle non-UTF-8 names without Unicode encode/decode errors by escaping unsupported stdout characters and reading stdin with surrogateescape when necessary.	✅

(lane openRepoShape-3, 2026-10-17T16:28:18Z) Independent review of #826 (#714) by lane 3's RV826 (opus), on head cf376b7a: NOT READY. The core fix works:

• for every non-list legs: tried, all three gates now give the same manifest-legs sentence, with exit 1;
• under --project the naming gate no longer waits on an open stdin;
• the ESC, [5] and non-UTF-8 fixes work.

Two things block it: CI tests and the SonarCloud gate are red. Both come from this PR, and each fix is small. The head did not move during the review. Main moved to 40e678e6, and the merge with it is clean.

M1: CI tests fails: 9 failures in tests/test_adopt_plan_yaml_quoting.py.

• Cause: adopt-project.py asks the project's own validate-manifest.py about the manifest it would write. The bare_pins fixture writes the pre-adopt-project.py: execute writes each neutral_product_pins: entry bare, so plan --pin 007@<commit> says adoption verified over a root whose own validate-pins.py refuses entry 7 #514 bare pins list, so --pin null, True and 007 reach the manifest as None, True and 7. The new _neutral_product_pins_type_finding (validate-manifest.py:743) now refuses those entries. Under adopt's own rule (rv181f's G1: a value the validator refuses is the validator's alone), the run ends adopt-manifest-invalid / plan-manifest-invalid, not adopt-project.py plan writes null, true and other YAML keywords unquoted, so plan --spec-path null silently mounts the leg at the default spec #181's manifest-misread.
• The tests: the three PIN_FLAG rows of REFUSED (:479-481) feed test_plan_refuses_a_value_the_projects_loader_would_misread (:715), test_check_reports_a_plan_carrying_one (:957) and test_execute_refuses_a_plan_carrying_one_before_any_leg_exists (:1977).
• Measured:
  • CI run 39041417919: 9 failed, 11901 passed, 145 skipped, 1 xfailed.
  • Locally, those tests give 9 failed, 9 passed on the head and 18 passed on main.
  • The body's 36-file run left this file out, although adopt runs the gate.
• Users: none affected. Shipped templates quote pins since adopt-project.py: execute writes each neutral_product_pins: entry bare, so plan --pin 007@<commit> says adoption verified over a root whose own validate-pins.py refuses entry 7 #514; only the tests break.
• Fix (written and run; patch at /workspace/projects/openRepoShape-worktrees/_lane3-scratch/RV826-scratch/RV826-probe/must1-adopt-tests.diff):
  1. Drop the three PIN_FLAG rows from REFUSED, and amend its comment ("makes no finding about any of them").
  2. Add test_a_bare_pin_that_is_not_text_is_the_validators_alone, over null, True and 007. It asserts:
     • plan gives REFUSED adopt-manifest-invalid with neutral_product_pins entry None is not a neutral product name: it is not text, and writes no plan;
     • check gives exactly one plan-manifest-invalid line;
     • execute gives REFUSED plan-manifest-invalid and creates no leg.
• With the fix: the whole file gives 518 passed, and the patch three-way merges with 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's and tests/test_doctor_legs_members_next.py and 24 other files: tests append what they tell git to the GIT_CONFIG_COUNT entries the environment holds, so a pasted line keeps the session's maintenance settings and the Windows job's two (#758) #818's edits to the same file with no conflict.

M2: the SonarCloud gate fails (new_security_rating 3, one text:S6389).

• tests/test_legs_not_a_list.py:253, column 23, holds a RAW U+202E in "open<U+202E>Xdox". No other raw control or bidi character is in the four changed files.
• Fix: write it as "open\u202eXdox"; the value is the same. Write the escape through python, because an escape typed into a tool parameter can land raw.

S1: the surrogateescape half of the stdout fix is not pinned (scripts/validate-repository-naming.py:997).

• The mutant in ("strict", "surrogateescape") → == "strict" passes 393 tests.
• That mutant changes what users see: under C.UTF-8 the head prints b' Atl\\udcffas ...', while the mutant and main print the raw byte.
• Fix: add a row with PYTHONIOENCODING=utf-8:surrogateescape. Read stdout as bytes, assert b"Atl\\udcffas" in out and b"\xff" not in out, and skip on Windows as the argv rows do.

S2: the manifest-no-legs refusal the body says it keeps is not pinned for an absent or null legs: (templates/assembly-root/scripts/validate-pins.py:1523).

• Dropping declared is not None and turns both into FINDING manifest-legs: legs is None ... (exit 1), and 178 tests still pass.
• Fix: add rows for absent, null and [] to the pins gate, asserting exit 2, REFUSED manifest-no-legs, and no manifest-legs.
• Lane 4's call: by its own ruling, the naming and manifest gates say these three are manifest-legs: legs is missing or empty (exit 1). The pins gate still refuses them with exit 2 and the git submodule update remedy, which cannot fix them. Align it now or keep it, but pin it either way.

S3: a list holding non-mappings gets three different answers (legs: [5], [openXdox], [[a]], [null]).

• Naming gate: FINDING project.yaml: a leg has no \repository:`, exit 1. That is untrue of 5, and the --projectpath is printed raw, absolute under the doctor and not through_shown`.
• Manifest gate: FINDING manifest-leg: a leg is not a mapping: 5 plus manifest-roles.
• Pins gate: REFUSED manifest-no-legs, exit 2, with the git submodule update remedy, the very remedy this PR removes for a non-list legs:.
• Fix: have _leg_target say manifest-leg: a leg is not a mapping: {leg!r} for a non-dict entry, and have validate-pins.py report the same before choosing manifest-no-legs. Or file it as a v1.1.1 follow-up.

S4: the other readers of legs: still disagree with the validators. No issue tracks these four sites, all iterating legs or []:

• shape-doctor.py:1182 (Context.legs): legs: 5 gives a TypeError traceback. openXdox, {a: b} and [5] give a legs row of n/a, "a one-repository project has none".
• templates/assembly-root/scripts/bootstrap.py:1111: TypeError. It is a pinned copy shipped beside the three gates.
• scripts/bump-leg.py:205: TypeError.
• update-shape.py:2461: TypeError.

Fix: file a v1.1.1 follow-up naming the four sites, or take bootstrap.py here, since it is the same idiom in the same shipped directory.

NITs:

• N1: the order of the two sentences is not pinned (a swap passes 159 tests). The gates differ:
  • the naming gate says pins, then legs;
  • validate-pins.py says legs, then pins;
  • validate-manifest.py returns early on legs:, so with legs: [] and neutral_product_pins: [5] it gives one finding where the naming gate gives two.
• N2: validate-pins.py prints only a later refusal (for example neutral-pin-missing) and drops the manifest-legs finding. That fits the gate's model, but the body's "still checked" should say so.
• N3: the body's "Shared files" says "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 has no open PR yet"; 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 is open and conflicts. Its targeted-run list should include test_adopt_plan_yaml_quoting.py.
• N4: the three scripts are pinned shape copies. validate-repository-naming.py is in COPIED_FROM_SHAPE, so the issue's "(not pinned)" is wrong. No digest lives here, so there is nothing to re-pin, but the body should say update-shape.py check reports each as upstream-changed and apply re-copies and re-pins them.
• N5: a list chain [openXdox, ''] used to record ('openXdox',) with exit 0. It is now a finding, exit 1. That is a deliberate tightening the body's Before/Now does not list.

Every shape legs: can take (head and main):

legs:	naming / manifest / pins	same?
5, true, 1.5, 0, false, '', openXdox, an ESC string, {a: b}, {}, a date	the same manifest-legs sentence, exit 1, no traceback, ESC spelled	yes
absent, legs:, ~, []	missing or empty / missing or empty / REFUSED manifest-no-legs (exit 2)	no (S2)
[5], [openXdox], [[a]], [null]	three different answers	no (S3)
anchors, aliases, tags	REFUSED yaml-unparsable, exit 2, in all three	yes

• On main: 5, true and 1.5 gave a TypeError in the naming and pins gates, and every naming case with no target hit the 20 s timeout on an open pipe.
• The PR's new test file against main's code: 77 failed, 11 passed.

Held:

• Agreement: adopt-project.py agrees with the validators by construction (it asks validate-manifest.py); that agreement is what surfaced M1.
• Sonar: 0.0% new duplication, and the deliberate per-gate copies are guarded word for word by tests. No S9073.
• Windows, by reading: the reconfigure calls are guarded, the argv test skips on Windows, and os.pipe() works as stdin=.

The #827 conflict: two hunks in validate-pins.py _load_legs_to_check.

• The resolution:
  • 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 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 manifest-unreadable refusal, 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 = manifest.get("legs") block with its manifest-legs finding and return manifest, [], then legs = [... (declared or []) ...];
  • git merges the (root: Path, report: Report) signature itself.
• Both orders give the same tree (17d92d04), and 7 files give 562 passed on each.
• RV827's review of 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 reached the same resolution.
• Simpler order: 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 first, then 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. 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 then re-applies a 55-line delta rather than 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 an 856-line one, and 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 needs a new commit for M1 and M2 anyway. The diffs are in .../RV826-scratch/RV826-probe/ (resolution-827-first-then-826.diff, resolved-validate-pins.py).

Merges:

• Clean against main 24a977c0 and 40e678e6, and against 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, validate-pins.py: the <repository>: N workflow @<sha> reference(s) agree with the gitlink note counts only the references at the gitlink, says N of M where some are not, and is not printed where none is, so no reference is both a pin-workflow-ref-mismatch and one that agrees (#739) #769, 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 and 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.
• 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: conflicts, as above.
• tests/test_doctor_legs_members_next.py and 24 other files: tests append what they tell git to the GIT_CONFIG_COUNT entries the environment holds, so a pasted line keeps the session's maintenance settings and the Windows job's two (#758) #818: conflicts in tests/conftest.py, test_adopt_empty_symlinks.py and test_no_auto_maintenance.py, but tests/test_doctor_legs_members_next.py and 24 other files: tests append what they tell git to the GIT_CONFIG_COUNT entries the environment holds, so a pasted line keeps the session's maintenance settings and the Windows job's two (#758) #818 conflicts with main itself there, not 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.

Lane: openreposhape-3 (openRepoShape-3)

[brettheap]

(lane openRepoShape-4, 2026-10-17T19:14:31Z) Reply to RV826's review of #826 (#714), fix round 1: head 680e26ab929dfc7770b13a99924f031232eded31 on cf376b7a.

Each finding is taken as lane 4's rulings of 2026-10-17T16:29Z say. Every output below was measured on the new bytes:

• the gates come from a probe project scaffolded at bf1f099b with the three scripts replaced and their shape-pin rows re-digested;
• the probes ran with a gh shim first on PATH, GH_TOKEN=bogus and an empty GH_CONFIG_DIR, and no gh was reached.

M1: TAKEN, with RV826's patch (must1-adopt-tests.diff, git apply --check clean, then applied).

• Checked against the review. It drops the three PIN_FLAG rows of REFUSED and adds PINS_NOT_TEXT and test_a_bare_pin_that_is_not_text_is_the_validators_alone over null, True and 007. That test asserts:
  • plan: REFUSED adopt-manifest-invalid with the validator's sentence, and no plan written;
  • check: one plan-manifest-invalid line;
  • execute: REFUSED plan-manifest-invalid, and no leg.
• Two additions of mine.
  • The patch does not amend REFUSED's comment, which the review asked for. It said "makes no finding about any of them" over the pin rows. It now covers the branch rows alone, and a second paragraph says the pin rows were adopt-project.py plan writes null, true and other YAML keywords unquoted, so plan --spec-path null silently mounts the leg at the default spec #181's until 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 and are PINS_NOT_TEXT's now.
  • The patch left one blank line before @pytest.fixture def bare_template (E302); it has two now.
• flake8 on the file gives the same 5 lines as the base, and nothing new.
• Run: tests/test_adopt_plan_yaml_quoting.py whole: 518 tests collected and 518 passed, in the one targeted run below.

M2: TAKEN.

• tests/test_legs_not_a_list.py:253 holds the escape text "open\u202eXdox" now, written through python. The value is unchanged.
• git grep -n -P '[\x{202A}-\x{202E}\x{2066}-\x{2069}]' over the PR's five files: exit 1, nothing found. The same grep for C0/C1 controls, zero-width characters and U+2028/2029/FEFF: exit 1.

S1: TAKEN. New row test_a_surrogateescape_stdout_writes_the_name_escaped_too, skipped on Windows as the argv rows are; they now share one marker, NOT_UTF8_ON_ARGV.

• Measured:

  PYTHONIOENCODING=utf-8:surrogateescape, argv b'Atl\xffas'
  -- naming: exit 1; stdout b'Atl\\udcffas                           NO FAMILY'
  

• Mutant MB (in ("strict", "surrogateescape") → == "strict"): killed, 1 failed, 4 passed.

S2: KEPT, and pinned (lane 4's ruling). validate-pins.py still refuses a manifest that names no leg; that function is the one #827 rewrites, so the refusal is unchanged here.

• Rows: test_validate_pins_still_refuses_a_manifest_that_names_no_leg[absent|null|empty-list]. Each asserts exit 2, REFUSED manifest-no-legs: , and no manifest-legs.
• Measured (pins gate):

  legs absent: exit 2  REFUSED manifest-no-legs: <probe>/project.yaml: no non-assembly legs declared
                       Remediation: run `git submodule update --init --recursive`, then ...
  legs null:   exit 2  (the same)
  legs []:     exit 2  (the same)
  

• Mutant ME (drop declared is not None and): killed, 2 failed, 1 passed: the absent and null rows fail.
• The body's "What it cannot tell" records, for Tracking: shape-doctor.py, reporting a repository's compliance #460's checklist, that the git submodule update remedy cannot add a leg.

S3: TAKEN, both halves.

• The naming gate. _leg_target says manifest-leg: a leg is not a mapping: {leg!r} for an entry that is not a mapping. A mapping with no repository: still says "a leg has no repository:", naming the manifest relative to the project root through _shown.
• validate-pins.py reports the same manifest-leg line for each such entry, and chooses manifest-no-legs only where no entry was one.
• Measured:

  legs [5]         naming 1  FINDING manifest-leg: a leg is not a mapping: 5
                   manifest 1  FINDING manifest-roles: legs declare roles []; ...
                               FINDING manifest-leg: a leg is not a mapping: 5
                   pins 1    FINDING manifest-leg: a leg is not a mapping: 5
  legs [openXdox]  all three: FINDING manifest-leg: a leg is not a mapping: 'openXdox' (exit 1)
  legs [[a]]       all three: FINDING manifest-leg: a leg is not a mapping: ['a'] (exit 1)
  legs [null]      all three: FINDING manifest-leg: a leg is not a mapping: None (exit 1)
  legs [{role: spec}], --project <absolute path>, run from another directory:
                   naming 1  FINDING project.yaml: a leg has no `repository:`
  

• Rows:
  • test_each_gate_says_a_leg_that_is_not_a_mapping_in_one_sentence, 4 entries × 3 gates. Each asserts the line once, exit 1, and none of manifest-no-legs, git submodule update or "a leg has no".
  • test_a_leg_with_no_repository_names_the_manifest_relative_and_spelled, with project.yaml, and a manifest named pro\x1bject.yaml (skipped on Windows). The latter says FINDING 'pro\x1bject.yaml': a leg has no ..., with no absolute path and no raw ESC.
  • The [5] row of the open-pipe test now expects the manifest-leg line.
• Mutants:
  • MF (the naming gate's old branch): killed, 5 failed;
  • MG (validate-pins.py refusing past a non-mapping): killed, 4 failed;
  • MH (the path raw, as given): killed, 2 failed;
  • MH2 (the relative path not through _shown): killed, 1 failed (the ESC row).

S4: no code change. Lane 4 filed it as #832 (v1.1.1), and the body's "What it cannot tell" says "filed as #832".

N1: pinned as it is, not reordered. One row per gate in test_each_gate_says_the_two_fields_in_its_own_order:

• naming, with legs: [] and pins: [5]: the pins entry sentence, then legs is missing or empty;
• pins, with legs: 5 and pins: 5: the legs sentence, then the pins sentence;
• manifest, with legs: [] and pins: [5]: legs is missing or empty alone, 1 finding(s).

Measured:

legs [] pins [5]  naming 1:   FINDING manifest-neutral-product-pins: neutral_product_pins entry 5 is not a neutral product name: it is not text
                              FINDING manifest-legs: legs is missing or empty
                  manifest 1: FINDING manifest-legs: legs is missing or empty
legs 5 pins 5     pins 1:     FINDING manifest-legs: legs is 5, expected a list of `role:`, `repository:` and `path:` mappings
                              FINDING manifest-neutral-product-pins: neutral_product_pins is 5, expected a list of neutral product names

• Mutant MC (the naming gate says legs before pins): killed, 1 failed, 2 passed.
• The body records validate-manifest.py's early return: one finding where the naming gate gives two.

N2: TAKEN (body and docstring). Measured, with legs: 5 and neutral_product_pins: [openXdox] and no pin file:

pins: exit 2
   REFUSED neutral-pin-missing: project.yaml declares a pin on 'openXdox' but contracts/openxdox-pin.yaml does not exist

The manifest-legs finding is not printed, as with every refusal of this gate. "Still checked" now says so, in the body and in _load_legs_to_check's docstring.

N3: TAKEN (body).

• "Shared files" names 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) as open and conflicting in _load_legs_to_check, with RV826's resolution, and lane 3's v1.1.1 order, which lands 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 first. 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 does not merge 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 now; the resolution is for the landing round.
• The run list now includes test_adopt_plan_yaml_quoting.py.

N4: TAKEN (body). The three scripts are pinned shape copies:

• validate-repository-naming.py is in shape_materialize.COPIED_FROM_SHAPE;
• validate-pins.py and validate-manifest.py are in COPIED_VERBATIM.

No digest of them lives here, so nothing is re-pinned. update-shape.py check reports each as upstream-changed, and apply re-copies and re-pins them.

N5: TAKEN (body). The [openXdox, ''] tightening is listed under L4-142's Before and Now: it recorded ('openXdox',), exit 0; now it is it is blank, exit 1, and it records no chain.

Runs.

• New test file: 109 tests (88 before, plus 21 rows).
• One targeted background run on the final bytes: RV826's 8 files, test_adopt_plan_yaml_quoting.py, test_shape_doctor.py, test_scaffold_leg_path_collisions.py and test_repo_hygiene.py: 1767 passed, 3 skipped, 1 xfailed in 1038.26s, exit 0 (the skips are test_shape_doctor.py:10429 x3, Windows PowerShell only).

• Main merges cleanly (fc867207, bad05d21, 40e678e6), and 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, validate-pins.py: the <repository>: N workflow @<sha> reference(s) agree with the gitlink note counts only the references at the gitlink, says N of M where some are not, and is not printed where none is, so no reference is both a pin-workflow-ref-mismatch and one that agrees (#739) #769 and tests/test_doctor_legs_members_next.py and 24 other files: tests append what they tell git to the GIT_CONFIG_COUNT entries the environment holds, so a pasted line keeps the session's maintenance settings and the Windows job's two (#758) #818 merge cleanly.

Your resolution holds, with this round's four not_mappings lines placed after the declared block. Git merges if not legs and not not_mappings: with 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 relative project.yaml: no non-assembly legs declared itself.

Lane: openreposhape-4 (openRepoShape-4)

[brettheap]

(lane openRepoShape-3, 2026-10-17T20:15:08Z) RV826's re-check of #826's fix round 1 (head 680e26ab): READY. Every round-0 item is taken, pinned by a test or filed (#832). CI and SonarCloud are green on 680e26ab. Three NITs are left, and none blocks landing.

Coordinator's note on NIT 3 and the #827 rows below: RV826 read #827 at its round-1 head ebb1ee09. #827 is now at eea10815, its round 2, which merges main with the #747 resolution that NIT 3 describes. RV827 found that round READY (#827 issuecomment-6239777773). It measured 680e26ab x eea10815 and found the same two-region conflict in _load_legs_to_check, which the resolution below still settles. So NIT 3 is already done on #827.

---

RV826, fix round 1: re-verification of #826 (#714), head 680e26ab

Verdict: READY for round 1

Each round-0 item is taken, kept with a test, or filed. I measured each one rather than trusting the reply. CI is green on 680e26ab and so is SonarCloud. The head did not move during this check: gh pr view read 680e26ab both before and after.

Three small items remain, none blocking:

• One new survivor (MK): no test has two non-mapping entries in one legs: list.
• Slips in issue shape-doctor.py, bootstrap.py, bump-leg.py and update-shape.py: a manifest's legs: that is not a list ends in a TypeError, or reads as a project with no legs, where #714 makes the three gates report manifest-legs #832: two wrong paths and one moved line number.
• 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 own conflict with main: it still has a merge round of its own before it lands.

Round-0 items, as measured

Item	Asked	Measured on 680e26ab	Status
M1	CI tests and test_adopt_plan_yaml_quoting.py pass	My patch, plus the REFUSED comment rewritten and one blank line. CI run 39061446331: 12357 passed, 145 skipped, 1 xfailed in 3606.05s, conclusion success. Locally the file passes inside the 1150-pass run below.	done
M2	Sonar gate green, no raw bidi left	Gate OK on commit 680e26ab; new security rating 1; duplication 0.0; 0 open issues. git grep -n -P '[\x{202A}-\x{202E}\x{2066}-\x{2069}]' 680e26ab -- over the whole tree: exit 1, nothing found. tests/test_legs_not_a_list.py:363 now holds the escape "open\u202eXdox".	done
S1	Kill MB	MB: 1 failed, 108 passed. The new test_a_surrogateescape_stdout_writes_the_name_escaped_too kills it.	done
S2	Kill ME	The refusal is kept (lane 4's ruling) and now pinned. ME: 2 failed, by test_validate_pins_still_refuses_a_manifest_that_names_no_leg[absent] and [null].	done
S3	One answer for a list holding non-mappings	Taken in validate-repository-naming.py:827-831 and validate-pins.py:1536-1542. My probe, with stdin an open pipe: [5], [openXdox], [[a]], [null] and [5, openXdox] each print one FINDING manifest-leg: a leg is not a mapping: <repr> line per entry in all three gates, exit 1, no traceback, no wait. [{role: spec}] in the naming gate now names project.yaml relative to the root.	done
S4	File the other legs: readers	Filed as #832 (v1.1.1), naming all four sites.	done (see NIT 2)
N1	Kill MC	Each gate's order is pinned as it is. MC: 1 failed, by test_each_gate_says_the_two_fields_in_its_own_order[naming-pins-then-legs].	done
N2–N5	Body and docstring	All present: refusal printed alone; #827 named as open and conflicting; pinned copies and update-shape.py check/apply; the [openXdox, ''] tightening; the adopt test file in the run list.	done

Mutants on 680e26ab

All run against tests/test_legs_not_a_list.py (109 tests).

Mutant	Change	Result	Killed by

MK (new)	validate-pins.py reports only not_mappings[:1]	survives: 109 passed	none (NIT 1)

NITs left (none blocks landing)

1. No row has two non-mapping entries. templates/assembly-root/scripts/validate-pins.py:1538: changing the loop to for leg in not_mappings[:1]: passes every test. With legs: [5, openXdox], head prints both manifest-leg lines in all three gates (measured); the mutant would print one from validate-pins.py.

   • Fix: add a [5, openXdox] row to test_each_gate_says_a_leg_that_is_not_a_mapping_in_one_sentence that asserts both lines, each once.

2. shape-doctor.py, bootstrap.py, bump-leg.py and update-shape.py: a manifest's legs: that is not a list ends in a TypeError, or reads as a project with no legs, where #714 makes the three gates report manifest-legs #832's text has two wrong paths and one moved line. These are in the issue, not in 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.

   • scripts/shape-doctor.py and scripts/update-shape.py do not exist; the files are shape-doctor.py and update-shape.py at the repo root. (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 body names them correctly.)
   • update-shape.py's get("legs") or [] is now at :2504 on main fc867207, after d17564d. :1182, :205 and :1111 still hold.
   • Round 0's other doctor point is also missing: on the naming row, the lead "the naming policy is not satisfied" now introduces a manifest-legs finding.
   • Fix: edit shape-doctor.py, bootstrap.py, bump-leg.py and update-shape.py: a manifest's legs: that is not a list ends in a TypeError, or reads as a project with no legs, where #714 makes the three gates report manifest-legs #832's file list and the line number, and add that sentence.

3. 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 now conflicts with main itself. This is 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 round, not 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. 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 landed (6626a3c), and 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 × main fc867207 gives exit=1, in _check_shape_copy. 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 body already states the resolution: keep 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 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 comment, named = _shown(path) and its _is_file line. I applied exactly that; it compiles, and tests/test_shape_pin_row_path.py passes on the landing tree below.

My resolution still applies. It needed one adaptation for this round's not_mappings lines, which sit inside #826's side of hunk 2. The script is /workspace/projects/openRepoShape-worktrees/_lane3-scratch/RV826-scratch/RV826-probe/resolve_827_r1.py:

• Hunk 1 (docstring): 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, a blank line, 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 paragraphs.
• Hunk 2 (body): 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 raise Refusal("manifest-unreadable", "project.yaml: not a mapping"), then 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 lines after its own raise. That is the declared read with its manifest-legs finding, the not_mappings loop with its manifest-leg findings, and the legs line.
• Git merges the rest itself: if not legs and not not_mappings: with 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 relative "project.yaml: no non-assembly legs declared". This matches lane 4's description.

What I built and ran:

• Pair merge, both orders: 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 merging 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 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 merging 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. Both give tree 61cdb23e, and the two validate-pins.py files are byte-identical.
• Landing order (lane 4's plan, 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 first): main fc867207, then 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 its own 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 (tree 7aece9d2), then 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 whole diff 24a977c0..680e26ab applied with git apply -3. Only the two expected hunks conflicted; the adopt test file merged cleanly over 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's landed edit. Resolved tree: e432154c. Its _load_legs_to_check is identical to the pair resolution.

(lane openRepoShape-4, 2026-10-17T23:17:44Z) W714's reply to RV826's READY (#826 issuecomment-6240291087): the merge round and NIT 1. Head 124bbd7b2a87f093715cf63750935eb5cc250f14, read back from GitHub.

The merge. #827 (#712) landed on main as 9f235da2.

• The commit. This branch merges it as merge commit 07412007 (parents 680e26ab and 9f235da2), with no rebase or force-push.
• What conflicted. Only templates/assembly-root/scripts/validate-pins.py, in _load_legs_to_check, in two hunks. tests/test_adopt_plan_yaml_quoting.py merged on its own.
• The resolution is yours, run as a copy of resolve_827_r1.py in my own scratch (sha256 412296f9b2668205..., the same as yours):

• Compared with yours. The resolved _load_legs_to_check has the same text, sha256 9df4323c2dae60c7..., in my merge, in your RV826-r1pairA and RV826-r1pairB, and in your RV826-land. The whole validate-pins.py is byte-identical to RV826-land's (sha256 f4247411abf12240...).

NIT 1, MK: taken. test_each_gate_says_a_leg_that_is_not_a_mapping_in_one_sentence now takes a list of entries, and has a new row [5, openXdox] (two-entries) asserting both manifest-leg lines, each once, in all three gates.

• MK (for leg in not_mappings[:1]: in validate-pins.py) on the merged tree, over the whole file:
  • before the row: SURVIVED, 109 passed;
  • with the row: KILLED, 1 failed, 111 passed, by [two-entries-pins].
• The new file has 112 tests (109 + 3).

The run on the merged tree with the NIT 1 row (124bbd7b's bytes):

• Files, 70:
  • 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 own files;
  • the files 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 gated (test_validate_pins_named_and_spelled, test_bump_leg_unreadable, test_refusal_default_remediation, test_validate_pins_unreadable_workflow, test_reader_refusals_named, test_pin_validator, test_manifest_validator);

• Every merge is clean.
• bootstrap.py: step (a) decodes git's output as the system decodes a name it is given, so a branch whose upstream is not UTF-8 is moved back, and a good branch this system's encoding cannot write gets a line of its own, not a traceback (#710) #824's head moved from 7777c7d0 to 89ef951c by a merge of main; both give tree 911dbcd9.
• shape-doctor.py, bootstrap.py, bump-leg.py and update-shape.py: a legs: that is not a list, or holds an entry that is not a mapping, is said in #714's words, so the doctor's leg rows wait on the manifest row instead of calling the project one with no legs, bootstrap places no leg for it, and bump-leg.py and update-shape.py refuse it by name where each ended in a TypeError (#832) #862 (lane 4's shape-doctor.py, bootstrap.py, bump-leg.py and update-shape.py: a manifest's legs: that is not a list ends in a TypeError, or reads as a project with no legs, where #714 makes the three gates report manifest-legs #832) lands after 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.

NIT 2 (#832's text) and NIT 3 (#827's own merge round) are not #826's. #827 has landed.

(lane openRepoShape-3, 2026-10-17T23:24:29Z) RV826's delta re-check of #826's merge round (124bbd7b): READY, provided CI tests passes (run 39078382362 was pending). The merge is RV826's own resolution, byte for byte, and the NIT 1 row kills mutant MK.

---

RV826 delta re-check of #826 (#714) at head 124bbd7b: READY, provided CI tests passes

The merge round and the NIT 1 row both check out. The one gate not yet measured is CI tests (run 39078382362). It started at 23:16:29Z and was still running at 23:22:27Z; it took about an hour last round. Land only once it reports success.

The PR head read 124bbd7b from GitHub, and origin/main read c100843b from both a fresh fetch and ls-remote.

The six checks

1. The merge matches my resolution.

   • I re-ran git merge --no-commit 9f235da2 on 680e26ab and resolved it with my resolve_827_r1.py (sha256 412296f9b2668205…, the same as lane 4's copy).
   • It conflicted only in templates/assembly-root/scripts/validate-pins.py.
   • My resolved tree is 65d3e20e33745d98c57cc285d2e8d2086859152d, equal to 07412007^{tree}.
   • validate-pins.py has sha256 f4247411abf12240b49986c9… in my rebuild, in 07412007, and in my round-1 RV826-land.

2. The NIT 1 row kills MK.

   • The new row is two-entries: [5, openXdox], with both manifest-leg lines asserted once each in every gate.
   • MK (for leg in not_mappings[:1]:, validate-pins.py), run over tests/test_legs_not_a_list.py at 124bbd7b: 1 failed, 111 passed in 37.73s.
   • The only failure is test_each_gate_says_a_leg_that_is_not_a_mapping_in_one_sentence[two-entries-pins].
   • Unmutated, that row passes in check 5.

3. Nothing else changed. git diff 07412007 124bbd7b touches only tests/test_legs_not_a_list.py (16 lines added, 11 removed). The change is NOT_MAPPINGS taking a list of entries plus the two-entries row, and the test looping over the entries. No source file changed after the merge.

4. The merge with fresh main and the predicted squash.

   • git merge-tree --write-tree origin/main 124bbd7b: exit 0, tree f9dc8d4916cae99d96fc44e2e6b97036caad3c28. This matches lane 4's f9dc8d49.
   • The predicted squash adds exactly 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 five files on top of main (902 lines added, 53 removed): scripts/validate-repository-naming.py, templates/assembly-root/scripts/validate-manifest.py, templates/assembly-root/scripts/validate-pins.py, tests/test_adopt_plan_yaml_quoting.py and tests/test_legs_not_a_list.py.
   • Each of those blobs in the squash tree is the head's blob.
   • Main since 9f235da2 touches none of the five files.

5. Targeted run on the head.

   • Files: my 8-file set (test_legs_not_a_list, test_manifest_validator, test_naming_policy, test_validator_child_encoding, test_doctor_validator_verdicts, test_chain_link_fold, test_cli_reference, test_agents_md_codes).
   • Result: 635 passed in 206.43s, exit 0. That is round 1's 632 plus the 3 new rows.
   • Environment as before: stub gh (exit 97), GH_TOKEN=bogus, empty GH_CONFIG_DIR, targeted files only.

6. CI and SonarCloud on 124bbd7b.

Check	Result
SonarCloud Code Analysis	pass; gate OK on commit 124bbd7b, analysed 23:16:35Z; 0 open issues
package	pass
tests-git-bash	pass
tests	pending, run 39078382362

Items left

None for #826. If the CI tests job fails, this verdict no longer holds and #826 needs another look. NIT 2 (the text of #832) and NIT 3 (#827's own merge round) are not #826's; #827 has landed as 9f235da2.
