Task 1 — Deterministic line endings

Status

Complete. The repository now declares the cross-platform line-ending policy, verifies it against tracked files (or an explicit test fixture), and performs the Docker-script check before their executable permissions are set in the core image.

Changed files

• .gitattributes — required LF/CRLF Git normalization contract.
• .editorconfig — editor-side UTF-8, final-newline, LF default and PowerShell CRLF policy.
• scripts/verify-line-endings.sh — tracked-file/fixture CRLF verifier.
• scripts/test-verify-line-endings.sh — LF and CRLF fixture regression test.
• docker/core.Dockerfile — image build invokes the verifier on /app/docker before chmod.

Red / green evidence

RED

bash scripts/test-verify-line-endings.sh exited 1 before the verifier existed. Its final assertion output was missing CRLF path: bad.sh; the test had captured the underlying attempt to run the absent verifier, so no CRLF paths could be reported. This confirmed the test was exercising the missing implementation rather than passing spuriously.

GREEN

After implementing the verifier and setting its executable mode:

$ bash scripts/test-verify-line-endings.sh
line-ending verifier tests passed

The test confirms that bad.sh, compose.yaml, and Dockerfile are all reported for CRLF, that the LF-only ok.sh is absent from the report, and that converting every fixture file to LF returns 0.

Commands and output summary

Command	Result
bash scripts/test-verify-line-endings.sh (before implementation)	Exit 1 (expected RED).
chmod +x scripts/verify-line-endings.sh scripts/test-verify-line-endings.sh	Set executable modes for both shell interfaces.
bash scripts/test-verify-line-endings.sh	Passed: line-ending verifier tests passed.
bash scripts/verify-line-endings.sh	Passed (exit 0) against tracked repository files.
bash -n scripts/verify-line-endings.sh scripts/test-verify-line-endings.sh	Passed.
git add --renormalize .	Completed; no existing tracked files required line-ending-only normalization.
git check-attr text eol -- ...	Confirmed LF attributes for .sh, Dockerfile, YAML, TypeScript, Python, and JSON examples.
git diff --check and git diff --cached --check	Passed.

Renormalization review

After git add --renormalize ., the staged diff contained only the intentional docker/core.Dockerfile change (3 insertions, 1 deletion). There were no unrelated or line-ending-only changes to review. New, untracked Task 1 files were then added explicitly.

Self-review

• Default mode uses git ls-files, so it inspects only tracked repository content and avoids untracked secrets and mounted volumes.
• Explicit-root mode is reserved for the isolated test fixture and uses find, as required.
• Detection uses LC_ALL=C grep -Il $'\r'; violations are printed as paths relative to the selected root and return exit 1.
• The Dockerfile runs the verifier immediately after copying Docker scripts and before chmod.
• The exact .gitattributes contract from the task brief is present verbatim.

Commit

Task implementation: ad07a75 (build: enforce portable line endings)

Concerns

None. The prescribed verifier and repository-integrity checks pass. A full Docker image build was not run because this task's required validation is the shell verifier suite; the Dockerfile change is structurally covered by the reviewed build instruction ordering.

Fix round 1 — PowerShell CRLF policy

Status

Complete. The verifier now applies the .gitattributes PowerShell exception: *.ps1 files may use CRLF, while CRLF remains a violation for the shell, YAML, and Dockerfile fixture inputs.

Changed files

• scripts/verify-line-endings.sh — skips .ps1 files before the CRLF rejection check.
• scripts/test-verify-line-endings.sh — adds a CRLF valid.ps1 fixture and asserts it is not reported; the fixture remains CRLF during the succeeding final verifier invocation.

Red / green evidence

RED

Before the verifier change:

$ bash scripts/test-verify-line-endings.sh
reported compliant CRLF PowerShell path: valid.ps1

The failure proves the new regression test exercised the existing incorrect behavior.

GREEN

After adding the .ps1 exception:

$ bash scripts/test-verify-line-endings.sh
line-ending verifier tests passed

The existing assertions still require bad.sh, compose.yaml, and Dockerfile to be reported, while valid.ps1 is rejected only if it is incorrectly reported. The final fixture verification passes with valid.ps1 still in CRLF form.

Command and output summary

Command	Result
bash scripts/test-verify-line-endings.sh (before change)	Exit 1: reported compliant CRLF PowerShell path: valid.ps1.
bash scripts/test-verify-line-endings.sh	Passed: line-ending verifier tests passed.
bash scripts/verify-line-endings.sh	Passed (exit 0; no output) for tracked repository files.
git diff --check	Passed (exit 0; no output).

Scope and self-review

The change is limited to the Important finding. It matches the existing lowercase *.ps1 pattern in .gitattributes, leaves the CRLF detection for every other file untouched, and does not address either deferred Minor finding.

Concerns

None.
