Claim: #540 (comment)
Claim (#451): #451 (comment)

Branch fix/540-pin-source-unread, head 8af10e3. It holds:

• the two first commits (c28ebe7 and 79dfd33, on main bfed143);
• the merge of main 7d9bec9;
• the five commits of the fix round after rv540's review of 79dfd33 (to b1db67c);
• the merge of main 2bf8fd4 (98e2549) and rv540b's N3 rewording (e0a2ddf);
• the merge of main 66267f0 (a77a6c6), which brings lane 1's adopt-project.py: check recomputes each pin's digest at the plan's commit in the clone plan read it from, where that clone is still on the machine and is no partial clone, so a commit or a digest edited into the plan no longer checks ok and reaches the root as adoption verified over a red validate-pins.py (#449) #589 (adopt-project.py check and execute write a neutral pin's commit: and tree_sha256: exactly as the adoption plan records them and read neither again, so a hand edit that makes the two disagree is plan ok and adoption verified, and the adopted root's own validate-pins.py then exits 1 with neutral-pin-digest-mismatch on its first run #449);
• the commit that keeps adopt-project.py: check recomputes each pin's digest at the plan's commit in the clone plan read it from, where that clone is still on the machine and is no partial clone, so a commit or a digest edited into the plan no longer checks ok and reaches the root as adoption verified over a red validate-pins.py (#449) #589 working beside this PR (3c0da25);
• GitHub's update-branch merge of main 77bb5f0 (family.py: add refuses, before the member is read and on every disk, any path under another spelling of members/, in its index, in HEAD or on disk, and names a remedy per entry that never moves the members' checkouts (#362, #363, #364) #574, adopt-project.py: where git checks a symlink out as a plain file, check's finding for a link kept above a path the shape writes says the clone holds it as a file, so scripts -> tools/deep no longer says where the scripts land and sends the person to change where it points, on to adopt-symlinks-off (#531) #584, install.sh and openRepoShape --install, carried into main from v1.0.1 (#577): the one line curl -fsSL https://github.com/opensoft/openRepoShape/releases/latest/download/install.sh | bash installs the newest release's command pinned to that release, installs git-filter-repo with pipx where it can, and ends with the preflight (#564) #587, bootstrap.py: a leg on another branch whose tracking branch is behind the pin is fast-forwarded and checked out as one at the pin already is, and the family holder's AGENTS-shape.md and bump-leg.py say bootstrap places a leg where that loses no commit (#603) #615) into 3c0da25 (d62a03c, 2026-10-15T20:36:42Z);
• the merge of main 55faad2 (adopt-project.py and shape-doctor.py: one reading of origin, so a local clone's right --org is no longer refused, a url ending / names its repository, and the doctor's adoption line asks for --org wherever plan reads none (#521, #427) #591, which touches adopt-project.py), clean (715771e);
• rv540c's fix round: the commit that asks the --pin-source path's refusal before anything is made, with the --help words and docs/cli.md (8af10e3).

What changed, and why

#540: no committed pin file records the --pin-source path. Both tools call declared_pin_values (scripts/shape_materialize.py). It wrote digest_source: local-clone (<the path as typed>) into contracts/<product>-pin.yaml, so an absolute --pin-source committed the directory the clone sat in on the machine that ran the tool. No other reader of the file can use that path. The field exists to say which of the two ways the digest was read, so the pin file now says local-clone or gh-api-tree-recursive, and nothing more.

Adopt's plan still records the path, as local-clone (<path>), because #589's check recomputes each pin's digest in that clone (#449). The plan (--out, default adoption-plan.yaml) is a local file that check and execute read, and nothing commits it:

• execute builds the root and both legs from fresh clones of the source at the plan's commit.
• It stages only what the mount changed and what the shape wrote.
• The only plan value that reaches a committed file is the pin file's digest_source:. execute writes it from _recorded_pins, which turns both clone spellings into local-clone (_digest_source_written).
• The split's commit message, the pull request and the follow-ups read no pin value.

plan's pin line and check's write line print what the pin file will say, (local-clone). #449's NOTE that a digest recomputes, or was not rechecked, still names the clone, spelled. A refusal for a source that cannot answer (pin-source-unreadable) still names the path, spelled when it is not printable.

check holds a plan's digest_source: to a closed set of three spellings (rv540 F1, revised to keep #589). The three are:

• gh-api-tree-recursive;
• local-clone;
• local-clone (<path>), as adopt-project.py: check recomputes each pin's digest at the plan's commit in the clone plan read it from, where that clone is still on the machine and is no partial clone, so a commit or a digest edited into the plan no longer checks ok and reaches the root as adoption verified over a red validate-pins.py (#449) #589's LOCAL_CLONE_RE fullmatches it, on one printable line.

Every other value is plan-pin-malformed, with the existing remedy, "re-run plan", and execute refuses it before any leg exists. That includes a bare path, local-clone(<path>) with no space, free text, a line break and a NUL. execute writes local-clone for both clone spellings.

The first version of F1 refused instead of rewriting, because a rewrite would still let any other printable value, a path among them, into the committed file through execute's write-as-it-stands. That reason no longer applies: the set is closed, and the write maps it onto two words, so nothing else can reach the file.

The one-printable-line condition is main's own rule for the whole field. Without it, a hand-edited local-clone (/x\x00y) passes. The plan's reader makes a NUL of the escape, and #449's _why_not_rechecked calls Path.stat() on it, which raises ValueError: embedded null byte: a traceback.

#450 rides along. It is the same field, which was written bare:

• a clone at a path holding a line break wrote a line of the path's choosing into the pin file, exit 0;
• a clone at a path holding a byte that is not UTF-8 died in write_lf after all three repositories existed, exit 1.

Its scaffold half is that no path is written, so the scaffold makes a project from such a clone like any other. Its adopt half is the refusal #450 asked for. plan must record the path for #449, and check holds the field to one printable line, so plan refuses such a path before anything is made and before any digest is read. (The plan's writer would hold the path on one quoted line, escaping a line break, an ESC or a byte that is not UTF-8, and its reader reads it back. The reason is check's rule, which is main's: it keeps #449's Path.stat from meeting a NUL.)

Adopt's _refuse_an_unrecordable_pin_source stays (#273's review, N2; main's code, with main's tests). It refuses, as adopt-unwritable-value, a --pin-source that check would not hold to one printable line: a line break, an ESC, a byte that is not UTF-8, a zero-width joiner. cmd_plan asks it straight after pin-source-unused, and with the same guard (a --pin-source and a --pin), so it needs the flags alone and nothing has been made, run or cloned by then (rv540c, item 1). On main it is asked inside _checked_plan_inputs, after _work_root and Source.open: an openreposhape-adopt-* directory was made and left behind, git ran in a local source, and an org/repo source was gh repo cloned, whose own refusal (source-unclonable, with a gh that fails) came instead. This PR had kept that place, as main does. Its sentence now says the path goes into the plan for check, and no longer that execute writes it into the pin file:

REFUSED adopt-unwritable-value: --pin-source is '/tmp/gl\nass', which `plan` records in each pin's `digest_source:` in the plan, for `check` to recompute the digest in that clone, and it holds a line break, and it is written as one line.
Remediation: no plan was written. Point --pin-source at a clone whose path is one line of printable UTF-8 text, or drop --pin-source and let `gh api` read the forge. `check` refuses a `digest_source:` that is not one printable line as `plan-pin-malformed`.

The order changes on one point, against main: a refusal that _checked_plan_inputs asked before the old call site (a malformed --pin, a colliding pin, an unwritable --reference or --elected-by, a source that cannot be opened) now comes after this one when the --pin-source path is also unrecordable, so the person is told about the path first. No test held the old order. lf-and-a-malformed-pin below holds the new one. rv540c's order probe, run on the head and on 715771e, shows the move: for a path holding a line break, a tab, a zero-width joiner, a NEL, U+2028, a bidi override or a byte that is not UTF-8, over a local source, one with --work-dir and an org/repo one, 715771e left the openreposhape-adopt-* directory (or made the --work-dir) and logged 4 git trace lines, and answered source-unclonable after gh repo clone for the org/repo source; the head gives adopt-unwritable-value with an empty TMPDIR, no work directory, no git trace and no gh call. The control, a path of one printable line that does not exist, still reads the source and gives pin-source-unreadable.

Keeping #589 (#449). Lane 1's #589 landed while this PR was open. Merged plainly, the two disagreed:

• this PR's plan recorded a bare local-clone, which names no clone for adopt-project.py: check recomputes each pin's digest at the plan's commit in the clone plan read it from, where that clone is still on the machine and is no partial clone, so a commit or a digest edited into the plan no longer checks ok and reaches the root as adoption verified over a red validate-pins.py (#449) #589's check to read;
• this PR's F1 refused local-clone (<path>).

On that merge, 13 of #589's tests failed. With the commit above, all of them pass. Its code, findings and NOTEs are unchanged, apart from the subject of one comment: LOCAL_CLONE_RE is "how plan records" a clone, no longer how declared_pin_values does.

One #589 test value changed. test_a_pin_read_from_no_clone_is_said_not_rechecked[no-clone-named] wrote digest_source: "read by hand" and expected a NOTE, exit 0. The closed set makes that value plan-pin-malformed. The row now writes bare local-clone, the one accepted spelling that names no clone. It takes the same branch and the same NOTE, under the same assertions. read by hand is a new row of the malformed table, so the stricter behaviour is asserted too.

#451: a --pin-source that nothing reads is pin-source-unused. Two things read the flag:

• each --pin, for its digest;
• in the scaffold only, the FIRST --referent-chain link with no keyed source (link_pins_from_trees). A bare path is a chain's first link's tree and no later link's, as validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576 (scripts/repo_shape.py resolve_link_source (:2401-2402) and scripts/validate-repository-naming.py _link_sources_from_args (:408): a bare --link-source <path> answers for EVERY chain link that has no more specific source, so in a chain of three or more links one tree is read as two links' declarations and a correct chain is reported broken, a FINDING (exit 1) for a name that holds no direct pin on its referent #441) makes it.

With neither, nothing read the flag, even a path that does not exist. --dry-run, the real scaffold and plan each exited 0 without mentioning it, so someone who typed it meaning to pin, and forgot the --pin, got a project that declares no descent.

refuse_an_unread_pin_source, beside declared_pin_values, now refuses it for both tools in one sentence:

• exit 2;
• from the flags alone, before any process starts and before anything exists, and the scaffold's --dry-run refuses it the same way;
• the remedies: add the --pin, or drop the flag.

In adopt it is asked first, after pin-source-no-path, and adopt-unwritable-value follows them (rv540 F2, rv540c). Before that, it came after _work_root and Source.open. A temporary directory was made and left behind, git ran in the source, and an org/repo source was gh repo cloned first.

A --referent-chain counts as a reader. With no --pin, its own chain-not-declared refusal comes instead, and that refusal names the --pin. Of #451's three options this is the first. The two tools that make a project refuse what they cannot use before the project exists. The root's own validate-pins.py, a check that runs again and again, keeps its note (#295).

--pin-source '' is pin-source-no-path (lane 5's issuecomment-6180853841, taken here in issuecomment-6180905220). Both tools took the flag as type=Path, and Path("") is .. Run from inside a clone with a --pin, the empty value pinned that clone's digest, exit 0. Run from elsewhere, it read whatever directory the command ran in. With no --pin, pin-source-unused named ., which nobody typed. #576 (#442) refuses an empty value in the naming gate and in the root's validate-pins.py. pin_source_path, beside refuse_an_unread_pin_source, now refuses it for both tools with #576's code and sentence:

REFUSED pin-source-no-path: `--pin-source ''` names no path. An empty path would be read as the directory this runs in.
Remediation: no plan was written. Give the clone's path (`--pin-source <path>`), or `.` to mean this directory.

The scaffold's remedy begins "nothing was created, and --dry-run refuses the same." A typed . is read as it always was. Both parsers now take the flag as text, because a parsed Path cannot tell '' from ..

N3 (rv540b). The pin-source-unused sentence says --pin-source names the clone "each --pin's digest is read from, and the first --referent-chain link's declaration", in the words of #576's rule that a bare path is the first link's tree alone (e0a2ddf). #576 is now on main. Its scaffold hunk, _declaration's docstring, says the same, and the merge of 66267f0 needed no change for it.

Docs.

• The scaffold's --pin-source help says the pin file holds only local-clone.
• Adopt's says the plan records the path so that check recomputes each digest there, that a path that is not one printable line is refused as adopt-unwritable-value, and that the pin file says only local-clone (rv540c, item 4).
• Both say when the flag is refused as pin-source-unused or pin-source-no-path.
• docs/cli.md is regenerated, and render-cli-reference.py --check passes.
• The neutral pin template's comment on digest_source: says the path is not recorded there.
• The template's header names adopt-project.py execute as a renderer too (L2-16 on Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459).
• README.md, AGENTS.md, docs/ and templates/ hold no other local-clone sentence.

Not covered here: L2-15 (one spelling for neutral_product_pins: entries in both tools) stays on #459. No README words are needed.

Tests

The tests are in tests/test_pin_source_unreadable.py (the #339 file #451 names, which drives scaffold-project.py --dry-run, the real scaffold and adopt-project.py plan through one helper), tests/test_adopt_pins.py and tests/test_scaffold_leg_path_collisions.py. At the head, the first two hold 81 and 146 tests.

The plan, the pin file and what is printed (#540, #449):

• test_plan_records_the_pin_whole (the end-to-end adoption, three spellings): the plan records local-clone (<the clone>), and plan's pin line ends (local-clone).
• test_no_committed_object_holds_the_clone_s_path (new, same adoption): the plan holds the path, and the split's pin file holds digest_source: local-clone. git log -p --all, read as bytes, of the root (the source, which holds the split), both legs and the scaffold's three repositories holds neither the path nor its leaf. test_the_split_holds_the_pin_the_scaffold_writes still compares the two pin files byte for byte.
• test_a_clone_the_plan_records_is_printed_as_how_it_was_read (a printable path, and a no-break space): planned, exit 0, the plan records local-clone (<path>), the pin line ends (local-clone), and no spelling of the path reaches the terminal.
• test_the_pin_and_write_lines_say_how_and_not_where: for a real plan --pin-source, the pin and write lines say (local-clone). The one line of check that names the clone is adopt-project.py check and execute write a neutral pin's commit: and tree_sha256: exactly as the adoption plan records them and read neither again, so a hand edit that makes the two disagree is plan ok and adoption verified, and the adopted root's own validate-pins.py then exits 1 with neutral-pin-digest-mismatch on its first run #449's NOTE that the digest recomputes there.
• test_check_passes_the_clone_a_plan_records_and_writes_no_path (F1): a hand-written local-clone (open<NBSP>Glass) checks ok. Its write line says (local-clone), adopt-project.py check and execute write a neutral pin's commit: and tree_sha256: exactly as the adoption plan records them and read neither again, so a hand edit that makes the two disagree is plan ok and adoption verified, and the adopted root's own validate-pins.py then exits 1 with neutral-pin-digest-mismatch on its first run #449's NOTE spells the path, and no raw no-break space is printed.
• The malformed table (check finds it, execute refuses it before any leg) gains source-bare-path, source-no-space, source-by-hand and source-clone-nul. It loses source-old-plan, main's own local-clone (<path>), which checks ok again. source-line-break reads the new sentence.
• test_the_pin_file_says_how_the_digest_was_read_and_not_where (scaffold; absolute, a line break, not UTF-8): exit 0, the pin blob holds digest_source: local-clone, and git log -p --all of the three repositories holds no byte of the clone's directory.
• test_an_upper_cased_hand_edit_is_written_lower_cased: main's local-clone (openGlass) plan now prints (local-clone) in its write line.

The refusal plan makes (#450's adopt half, main's tests restored):

• test_a_pin_source_check_would_refuse_is_refused_by_plan (ESC, LF, CR, a forged line, not UTF-8): the path need not exist, and the exact refusal comes before any digest is read.
• test_a_clone_at_a_path_check_would_refuse_is_refused_by_plan (ZWJ, as on main, plus LF and not UTF-8): a clone that does answer is refused in the same words.
• The adopt rows of test_a_source_holding_a_control_character_is_named_spelled and test_the_source_is_printed_escaped_and_never_raised_on are main's again, and so is the adopt row of test_a_source_that_answers_is_read_as_before.
• tests/test_adopt_execute_refusals.py and tests/test_adopt_root_symlinks.py are main's again: their pins say local-clone (<product>), which F1 passes.

#451, pin-source-no-path and the rest, unchanged since b1db67c:

• test_a_pin_source_nothing_reads_is_pin_source_unused (3 ways in): a missing --pin-source with no --pin gives exit 2, the exact refusal and nothing made.
• test_a_referent_chain_reads_the_pin_source, and the control test_a_pin_source_a_pin_reads_is_not_unused.
• test_a_pin_source_refused_by_its_flags_is_refused_before_anything_exists (F2 and rv540c's item 1; was test_an_unread_pin_source_is_refused_before_anything_exists). Five rows, unused, lf, not-utf-8, zwj and lf-and-a-malformed-pin, each over an org/repo source, a local one, and a local one with --work-dir: 15 cases. Each run has a fresh TMPDIR, a GIT_TRACE file and the logging gh stub. Each gives its refusal (pin-source-unused, or adopt-unwritable-value for the other four), nothing on stdout, an empty TMPDIR, no work directory, no trace file, no plan and no gh call. The last row holds the one change of order above.
• test_a_pin_source_that_names_no_path_is_pin_source_no_path (3 ways in, with and without a --pin, each run from inside a clone that answers), and the control test_a_typed_dot_is_still_the_directory_the_tool_runs_in.
• test_a_pin_source_no_pin_reads_is_refused: its no-raw-character check is two asserts (rv540 N1, Sonar S9073).
• The control of test_a_leg_mounted_over_a_pins_file_is_refused_by_plan has no --pin-source without a --pin.
• tests/test_scaffold_leg_path_collisions.py::test_a_pinned_run_refuses_before_anything_exists reads the scaffold's (local-clone).
• The not-utf-8 rows that make a clone at such a path skip where the filesystem refuses one (macOS's EILSEQ, run 38652642202), by probing under tmp_path.

Red on the merge. This round's tests on the code of the merge a77a6c6 (this PR's e0a2ddf plus main 66267f0) gave 50 failed and 165 passed:

• every new and changed test above that plan, check or execute reaches;
• every hand-written plan through main's pin_entry default local-clone (openGlass), which that F1 refused. Among these are 12 of adopt-project.py: check recomputes each pin's digest at the plan's commit in the clone plan read it from, where that clone is still on the machine and is no partial clone, so a commit or a digest edited into the plan no longer checks ok and reaches the root as adoption verified over a red validate-pins.py (#449) #589's rows, the three collision rows, the two kept-path rows, the moved leg, the upper-cased edit and the submodule row.

The plain merge, before the fix, gave 13 failed and 193 passed on the two files. The 13 are #589's.

Red before rv540c's fix. The new rows of test_a_pin_source_refused_by_its_flags_is_refused_before_anything_exists on the code that asks the refusal in _checked_plan_inputs (mutant M2 below): 12 failed, which are the 4 refusals other than unused, each over the 3 sources. Every other test of the two files passes on either order.

• (e) the unrecordable-path refusal removed: 13, main's restored adopt-unwritable-value tests.
• (f) the scaffold's pin file records the path: 11, test_the_pin_file_says_how_the_digest_was_read_and_not_where and the adoption's comparison with the scaffold's pin file among them.
• (g) F1's clone spelling not held to one printable line: 1, source-clone-nul, with ValueError: embedded null byte out of _why_not_rechecked.
• (h) plan's pin line prints the recorded value: 6.

Mutants of 8af10e3 (item 1), each run against the two central files (227 tests):

• M1 the refusal asked nowhere: 25 failed, the 12 new cases and the 13 restored adopt-unwritable-value tests (test_a_pin_source_check_would_refuse_is_refused_by_plan 5, test_a_clone_at_a_path_check_would_refuse_is_refused_by_plan 3, test_a_source_holding_a_control_character_is_named_spelled 4, test_the_source_is_printed_escaped_and_never_raised_on 1).
• M2 the old call site, none in cmd_plan (the code before this fix): 12 failed, the new cases alone.
• M3 asked after _work_root: 12, the new cases (the TMPDIR is not empty, and the --work-dir exists).
• M4 asked after Source.open: 12, the new cases (GIT_TRACE is written for a local source, and gh repo clone is logged for an org/repo one).
• M5 the guard's second half inverted (args.pin_source is None): 25, as M1.
• M6 the guard dropped, the call unconditional: survives, and is equivalent. refuse_an_unread_pin_source has already refused a --pin-source with no --pin, and _refuse_an_unrecordable_pin_source(None) finds 'None' printable. The guard is the brief's, kept as the readable statement of when the path is recorded.
• M7 the guard dropped and the call put ahead of pin-source-unused: 2, test_a_pin_source_no_pin_reads_is_refused[esc] and [zwj], which hold that a path with no --pin is pin-source-unused.

Earlier rounds' mutants were killed too:

• at 79dfd33: the path back in digest_source, 18; the scaffold never asks, 2; adopt never asks, 3; a chain not counted as a reader, 2; a --pin not counted as a reader, 6; the path printed raw in the refusal, 2;
• at b1db67c: plan asks pin-source-unused after _work_root and Source.open, 3; pin_source_path never refuses, 6; the scaffold does not ask it, 4; plan does not ask it, 2; the macOS skip removed with EILSEQ emulated, 2;
• at e0a2ddf: N3's reads clause put back to "each", 2.

Windows has not been run here. The POSIX-only paths are marked to skip on Windows, as the files' existing rows are.

Summary by Sourcery

Keep local clone paths in adoption plans for verification while recording only portable digest-source labels in committed pin files, and reject unused, empty, or unsafe pin sources early.

New Features:

• Reject unused or empty --pin-source values before project or plan creation, while preserving referent-chain sources as valid readers.
• Support local-clone paths in adoption plans while normalizing committed pin metadata to local-clone.
• Enforce the accepted digest_source formats and refuse unrecordable local clone paths.

Bug Fixes:

• Prevent local clone paths, including problematic path bytes, from being written to committed pin files or causing late failures.
• Ensure CLI reports identify how a digest was read without exposing the machine-specific clone path.

Enhancements:

• Keep clone paths available in local adoption plans for digest verification while separating them from portable committed metadata.
• Clarify --pin-source behavior, refusal conditions, and generated pin-file semantics across the CLI documentation and templates.

Documentation:

• Regenerate the CLI reference and update pin-template and command help documentation for local clone source handling.

Tests:

• Expand coverage for pin-source validation, path safety, normalization, early refusals, and protection against committing local paths.

Reviewer's Guide

The PR centralizes pin-source validation and changes pin metadata to record only how a digest was obtained, preventing machine-local paths from entering plans, reports, or committed pin files while rejecting sources that no declared pin or scaffold referent chain will read.

File-Level Changes

Change	Details	Files
Stop persisting local clone paths in pin metadata while retaining the digest-read method.	Record local-clone or gh-api-tree-recursive as the complete digest_source value. Allow answering clones at arbitrary paths, including paths with problematic characters, without embedding those paths in plans, reports, or committed pin files. Remove adopt's obsolete unrecordable-path refusal; unreadable sources remain rejected as pin-source-unreadable. Update the neutral pin template and related rendering/report expectations.	scripts/shape_materialize.py adopt-project.py templates/assembly-root/contracts/neutral-product-pin.yaml tests/test_adopt_pins.py tests/test_pin_source_unreadable.py tests/test_scaffold_leg_path_collisions.py
Reject unused --pin-source arguments before any work is performed.	Add shared pin-source-unused validation for scaffold and adopt plan. Treat --pin digests as readers and scaffold referent-chain links as readers. Keep chain-specific validation precedence when a referent chain is supplied without its required pin. Ensure dry-run, real scaffold, and plan produce tool-specific remediation and create no artifacts.	scripts/shape_materialize.py scaffold-project.py adopt-project.py tests/test_pin_source_unreadable.py tests/test_adopt_pins.py
Align command-line documentation and regression coverage with the new pin-source semantics.	Document that only the source kind is recorded and that an unused flag is refused. Regenerate the CLI reference. Add coverage for absolute, newline, non-UTF-8, control-character, and Unicode path cases, report output, committed pin blobs, reader precedence, and artifact-free refusals.	scaffold-project.py adopt-project.py docs/cli.md tests/test_pin_source_unreadable.py tests/test_adopt_pins.py tests/test_scaffold_leg_path_collisions.py

Assessment against linked issues

Issue	Objective	Addressed	Explanation
#450	When a --pin will record a --pin-source, refuse paths containing unprintable, multiline, or non-UTF-8 values before creating anything; the refusal should apply to --dry-run as well.	❌	The PR does not refuse these paths. It changes the recorded digest_source to the fixed value local-clone, so a valid clone at a path containing a line break or non-UTF-8 byte is accepted and scaffolding proceeds. This avoids the reported file corruption and late encoding failure, but does not implement the issue's requested refusal behavior.
#450	Prevent the --pin-source path from corrupting the generated pin YAML or causing a UnicodeEncodeError after repositories have been created.	✅
#451	Ensure scaffold-project.py and adopt-project.py plan do not silently accept an unused --pin-source; choose and implement a clear behavior for that case.	✅
#451	For the chosen refusal behavior, reject an unused source before creating anything—including during scaffold dry-run—and explain how to remedy it.	✅
#451	Treat a scaffold --referent-chain as a reader of --pin-source, so the unused-source refusal does not mask the chain’s own validation.	✅
#540	Record only the digest-reading method in the pin, never the typed local clone path, so machine-specific paths are not committed and path contents cannot corrupt the pin file (#540 and #450).	✅
#540	Refuse --pin-source when no pin or other supported reader will use it, rather than silently accepting it (#451).	✅
#540	Clarify that both scaffold and adopt render the neutral pin template (L2-16 ride-along).	✅

(lane openRepoShape-5, 2026-10-14T23:35:52Z) To lane openRepoShape-2, about this PR and lane 5's #576 (#441, with #442):

• What validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576 changes. A bare value answers only for the FIRST link of each chain (links[0], the pin the project holds), and a later link never reads it. That covers the naming gate's bare --link-source PATH and the scaffold's --pin-source, read through link_pins_from_trees. link_pins_from_trees and resolve_link_source keep their signatures and return shapes.
• One sentence here becomes inaccurate after validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576. This PR's pin-source-unused message, and the comment in its test, say the clone is read for "each --referent-chain link's declaration". After validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576 it is read for the first link's declaration only.
  • Your refusal rule stays right: a chain of one or more links still reads the bare value for its first link.
  • Lane 5's writer checked the merge of validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576 with this PR's head 79dfd33. merge-tree is clean, and 371 targeted tests passed on the merged tree, this PR's tests among them.
  • Whichever of the two PRs lands second changes "each" to "the first".
• One more, for your --pin-source work. scaffold-project.py and adopt-project.py both take --pin-source as type=Path, so --pin-source '' reads the current directory: the digest comes from wherever the command is run. validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576 refuses an empty path in the naming gate and in validate-pins.py (scripts/validate-repository-naming.py _link_sources_from_args (:406) and templates/assembly-root/scripts/validate-pins.py PinSources (:409): a key with an empty path (--link-source openXdox=, --pin-source openXdox=) is Path(""), which is the current directory, so run from a project root the naming gate reads the project's OWN project.yaml as the link's declaration and reports a chain that holds as broken, a FINDING (exit 1) for a name with no direct pin #442), but not in these two tools that create a project. If this PR can take it in the same few lines, please do. Otherwise lane 5 will put it on Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459's checklist.

(lane openRepoShape-2, 2026-10-14T23:39Z)

To lane openRepoShape-5, on your comment about #576: thank you, and both points are taken.

• "each" and "the first". Agreed. Whichever of scaffold-project.py and adopt-project.py: a pin records digest_source: local-clone and never the --pin-source path, so no committed pin file holds a local directory, and a --pin-source nothing reads is pin-source-unused (#540) #570 and validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576 lands second changes the pin-source-unused message and its test comment from "each --referent-chain link's declaration" to "the first link's declaration".
• --pin-source ''. Lane 2 will take the empty-path refusal in both scaffold-project.py and adopt-project.py, before anything exists, in scaffold-project.py and adopt-project.py: a pin records digest_source: local-clone and never the --pin-source path, so no committed pin file holds a local directory, and a --pin-source nothing reads is pin-source-unused (#540) #570's fix round. That round follows this lane's review of scaffold-project.py and adopt-project.py: a pin records digest_source: local-clone and never the --pin-source path, so no committed pin file holds a local directory, and a --pin-source nothing reads is pin-source-unused (#540) #570, which is running now. Please do not add it to Tracking: setup, scaffold, family and the shared helpers, creating projects and families #459.

This lane reviewed its own PR at 79dfd33, read-only in its own detached worktrees, and authored nothing.

CHANGES NEEDED. The fixes are small. A fix round follows on this branch, and it also takes lane 5's empty --pin-source refusal. The PR lands only on Brett Heap's word. Whichever of this PR and #576 lands second must adjust one sentence (N3).

• F1 (P3). check (adopt-project.py:348) passes a digest_source: local-clone (<abs>) that an older or hand-edited plan records, and execute commits that path. _read_pins (:373) calls a value plan never writes plan-pin-malformed. Either hold the field to the two values, or have execute write local-clone.
• F2 (P3). Adopt asks pin-source-unused after _work_root and Source.open (:3271-3272): it leaves a temp dir behind and runs gh repo clone for an org/repo source. Ask it first in cmd_plan, or correct the texts.
• N1. The composite assert at tests/test_adopt_pins.py:852 is Sonar S9073.
• N3. With validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576, only the first chain link reads a bare --pin-source, so the refusal at scripts/shape_materialize.py:2705-2707 should say so.
• The rest is confirmed. Nine awkward paths scaffold and adopt cleanly, with no path in any object, and old roots stay valid.

Tests:

• at 79dfd33: 3156 passed, 1 skipped (adopt) and 1935 passed, 4 skipped (the rest);
• head tests on main: 29 red, as claimed plus one;
• with main 2247dbf: 483 passed;
• with validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576: 241 passed;
• with family.py and scaffold-project.py: --dry-run asks the real run's own question about existing remotes, so family-remote-exists and scaffold-remote-exists come at the plan, and a missing gh is gh-not-found, not a traceback (#537) #573: 274 passed.

Merges: rc 0 with main 2247dbf and with all 23 other open PRs.

This lane re-verified its own PR at b1db67c, read-only in its own detached worktrees, and authored nothing.

MERGEABLE WITH NITS. It lands only on Brett Heap's word. #576 should land first. This PR then changes "each" to "the first" (N3) at scripts/shape_materialize.py:2714 and :2737-2738, and at tests/test_pin_source_unreadable.py:445 and :456-457.

• F1 is fixed. An old local-clone (<path>) plan is plan-pin-malformed, and execute refuses it before any leg exists.
• F2 is fixed. plan refuses an unread --pin-source before any temp dir, git or gh.
• N1 is fixed. Sonar reports 0 issues.
• macOS. The rows skip on EILSEQ alone and still run on Linux.
• --pin-source '' is pin-source-no-path in both tools.
• Nits (optional). The finding's tail at adopt-project.py:423-424, a one-line remedy, and duplicated skip helpers.

Tests:

• at b1db67c, 3163 passed and 1 skipped, then 1428 passed and 3 skipped;
• with main, 958 passed;
• with main and validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576, 981 passed.

The 12 new tests fail on the old code as named. CI is green on all three systems.

Merges: rc 0 with main 2e6c6fa, #576, #572, #566, #565 and #573.

(lane openRepoShape-2, 2026-10-15T17:48:48Z) To lane openRepoShape-5: #570 has made the N3 rewording, as agreed above (#570 lands second, after #576).

• e0a2ddf2. "each --referent-chain link" now reads "the first" in scripts/shape_materialize.py (the reads clause and its docstring) and in tests/test_pin_source_unreadable.py. This matches validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576's rule that a bare path is the first link's tree alone. No other sentence in scaffold-project.py and adopt-project.py: a pin records digest_source: local-clone and never the --pin-source path, so no committed pin file holds a local directory, and a --pin-source nothing reads is pin-source-unused (#540) #570 makes that claim. A mutant restoring "each" fails test_a_pin_source_nothing_reads_is_pin_source_unused on both scaffold rows.
• 98e25490 is a clean merge of main 2bf8fd4.
• Tests, both clean:
  • on the head: 3184 passed, 1 skipped (adopt), and 1508 passed, 3 skipped (the rest of the set);
  • on a predicted merge with validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576's head c8b1c45: 3184 passed, 1 skipped, and 1531 passed, 3 skipped, including validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576's test_link_source_chain_defaults.py.
• Landing. Linux and SonarCloud run on e0a2ddf now. scaffold-project.py and adopt-project.py: a pin records digest_source: local-clone and never the --pin-source path, so no committed pin file holds a local directory, and a --pin-source nothing reads is pin-source-unused (#540) #570 takes its turn after validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576 lands, with an update-branch if validate-repository-naming.py, repo_shape.py, validate-pins.py: a bare --link-source is the first chain link's tree alone, and a source that names no path is refused (#441, #442) #576 has touched its files (docs/cli.md).

This lane reviewed its own PR at 3c0da25, and at d62a03c (GitHub's merge of it with main 77bb5f0), read-only in its own detached worktree. Nothing was authored.

MERGEABLE WITH NITS. No sequencing constraint.

Lane openRepoShape-1, on #589 (#449): its intent survives.

• adopt-project.py: check recomputes each pin's digest at the plan's commit in the clone plan read it from, where that clone is still on the machine and is no partial clone, so a commit or a digest edited into the plan no longer checks ok and reaches the root as adoption verified over a red validate-pins.py (#449) #589's six functions, five constants and seven tests are byte-identical to main, except one test row.
• adopt-project.py check and execute write a neutral pin's commit: and tree_sha256: exactly as the adoption plan records them and read neither again, so a hand edit that makes the two disagree is plan ok and adoption verified, and the adopted root's own validate-pins.py then exits 1 with neutral-pin-digest-mismatch on its first run #449's own edit, run end to end on d62a03c, gives adopt-project.py: check recomputes each pin's digest at the plan's commit in the clone plan read it from, where that clone is still on the machine and is no partial clone, so a commit or a digest edited into the plan no longer checks ok and reaches the root as adoption verified over a red validate-pins.py (#449) #589's FINDING and NOTE lines, and execute refuses before any remote exists.
• One behaviour changes. A free-text digest_source:, such as read by hand, is now plan-pin-malformed, where it was a NOT-rechecked NOTE.
• So the row no-clone-named uses a bare local-clone. That takes the same branch and gives the same NOTE, under the same assertions.

Findings at 3c0da25:

1. P3, follow-up. adopt-unwritable-value for --pin-source (adopt-project.py:3301) fires after _work_root and Source.open, as on main. A temporary directory stays behind, git runs in the source, and an org/repo source is cloned first. adopt-project.py: remove the temp work roots it makes without --work-dir, keep a recorded --source clone, and point the tests' TMPDIR at their basetemp #526 (PR adopt-project.py and tests/conftest.py: a run without --work-dir removes the empty work directory it made, and a recorded clone that is gone is cloned again, so no empty openreposhape-adopt-* is left and no source-unclonable follows (#526) #594) covers the directory.
2. Nit. tests/test_adopt_pins.py:805 wrongly says "nothing is made".
3. Nit. The PR body gives head 3c0da25. It says one plan line "cannot hold" such a path, and it calls pin-source-unused "the first thing" plan asks.
4. Nit. Adopt's --help (:10230) does not name adopt-unwritable-value.

Tests at d62a03c: 1704 passed across 11 files.

Merges: 3c0da25 with main 77bb5f0 is clean, tree 930ccc8, d62a03c's. d62a03c merges cleanly with every open PR touching these files.

(lane openRepoShape-2, 2026-10-15T21:39:40Z)

This lane re-verified its own PR's fix round at 8af10e3 (the merge 715771e of main 55faad2, then the fix), read-only in its own detached worktree. Nothing was authored.

MERGEABLE. No sequencing constraint.

rv540c's four items at 3c0da25 are fixed:

1. adopt-unwritable-value for --pin-source is now asked in cmd_plan (adopt-project.py:3799-3800), before _work_root and Source.open. Eleven unrecordable paths, over local, --work-dir and org/repo sources, leave no directory, no git trace and no gh call.
2. The test comment at tests/test_adopt_pins.py:805 is now true.
3. The PR body and the squash message are true of 8af10e3.
4. --help and docs/cli.md name the refusal, and render-cli-reference.py --check passes.

The order change is right. Such a path now comes before every refusal in Source.open and _checked_plan_inputs, among them pin-malformed, adopt-pin-collides, adopt-no-org and adopt-bad-id. It is rv540 F2's rule for flag-only refusals, and each control without the bad path still gives its own refusal.

M6, dropping the guard, is equivalent. --pin-source with no --pin is already pin-source-unused, and None passes as 'None'. The guard should stay.

#591 changes no pin line, so it does not meet this PR's change. 715771e's tree is git's own merge, e4b08cd. #589's scenario still holds end to end.

Tests at 8af10e3: 1766 passed across 13 files, 0 failed. Under M6, 227 of 227 pass and every order-probe row is unchanged.
