Verdict: ACCEPT

Acceptance matrix

Criterion	Status	Implementation evidence	Test evidence
AC1	PASS	run_devloop calls create_pull_request only when [ -n "$PASS_COMMIT" ] (devloop:2160-2163), reaching create_draft_pull_request which writes a body file and runs gh pr create --draft --fill --base --head --body-file (devloop:3630). Body always begins with # Devloop Draft PR so it is non-empty (devloop:3590-3610).	tests/devloop_test.sh:1124 asserts gh pr create line precedes agent reviewer 1; :1126 asserts [[ -s pr-body.md ]]. Full suite green firsthand: ok - PR-backed accept comments.
AC2	PASS	Body table emits Source spec, Spec title (spec_title, devloop:3567-3577), Base branch, Head branch, Latest commit with none fallback (devloop:3589), plus an Acceptance Criteria section using criteria_block or the literal No parsed acceptance criteria. fallback (devloop:3605).	:1128-1135 assert title E2E PR Accept, Base branch+base_branch, Head branch+feat/e2e-pr-accept, Latest commit+[0-9a-f]{7,} regex, and criterion Write the result file.. Fixture seeds these in make_loop_repo (:886-889), so assertions are non-vacuous.
AC3	PASS	gh pr create now passes --body-file "$body_file" (devloop:3630). Verified against gh source: --body-file sets opts.BodyProvided=true and the create path applies if opts.BodyProvided { state.Body = opts.Body } after autofill, so the explicit body overrides --fill's commit-derived body; --fill only supplies the title.	:1125 asserts --body-file present in the captured gh command log.
AC4	PASS	ensure_pull_request runs lookup_pull_request, and if [ -n "$PULL_REQUEST" ]; then return 0; fi before create_draft_pull_request (devloop:3651-3653). No gh pr edit path exists anywhere, so an existing body is never touched.	:1190-1211 seed an existing PR URL, run the loop, then :1207 fails if gh pr create ran and :1206 asserts the existing URL is surfaced. Firsthand: ok - PR-backed existing PR reuse.
AC5	PASS	Fake gh pr create parses --body-file and copies it to $state/pr-body.md (tests/devloop_test.sh:610-613,624-626); PR-backed loop asserts body content.	Red evidence in track (not ok - created PR body missing) is credible: old gh pr create had no --body-file, so pr-body.md is never written and [[ -s ... ]] fails. Green verified firsthand; ok - 100% project function coverage.

Engineering quality matrix

Area	Status	Evidence
Correctness	PASS	Call-site vars ($spec, $criteria_file, $FINAL_COMMIT) are all in run_devloop scope (devloop:1996,2001,2146). spec_title awk matches the first level-1 # line in the file and `
Test quality	PASS	Assertions trace to fixture content (make_loop_repo writes # E2E PR Accept and 1. Write the result file.), so they verify real output not echoes. Reuse, create-fail, lookup-fail, and comment-fail paths each have a dedicated scenario. Commit-hash regex check guards against a placeholder.
Maintainability	PASS	Two small cohesive helpers added; extra args threaded positionally through create_pull_request→ensure_pull_request→create_draft_pull_request, matching the file's existing convention. No control-flow added to a busy path.
Architecture boundaries	PASS	Body generation lives beside the other PR helpers and reuses the canonical criteria_block instead of reparsing the spec.
Simplicity	PASS	Heredoc body is direct. The inline -f/-n guard before criteria_block is justified (it protects criteria_block's < "$criteria_file" redirect from a missing file), not redundant complexity.
Security	PASS	mktemp avoids predictable temp paths; --body-file avoids multiline word-splitting. Heredoc variable expansion does not re-evaluate command substitution from variable contents, so a hostile spec path/title cannot inject commands. No new dependencies.
Operational safety	PASS	Failures route through the existing PULL_REQUEST_ERROR/pr-error path; temp file cleaned before return; reuse path returns early and untouched; PR creation stays non-interactive.

Review flags

• Silent decision: absent - Keeping --fill for title while overriding the body via --body-file, and leaving PR reuse unchanged, are both recorded in the track Design tradeoffs.
• Scope drift: absent - Changes confined to PR-creation helpers, the post-commit call site, and tests/devloop_test.sh, matching the spec In-scope list. README (read directly) documents --create-pr generically and is reinforced, not contradicted, by the populated body, so no doc update was needed.
• Missing test: absent - The populated-body behavior has targeted, non-vacuous assertions across content, flag usage, reuse, and failure paths.

Findings

None.

Missing tests

• None blocking. Optional hardening (low risk): the No parsed acceptance criteria. fallback branch and verification that the temp body file is removed after a gh pr create failure are not asserted directly; both are simple guarded paths. The none commit fallback is unreachable from the only caller (PR creation is gated on [ -n "$PASS_COMMIT" ] and FINAL_COMMIT="$PASS_COMMIT"), so it is defensive rather than a true coverage gap.

Fix instructions

None.

Notes

• The one risk the fake-gh test cannot cover is whether real gh lets --fill override --body-file. Confirmed via gh source (pkg/cmd/pr/create/create.go): --body-file sets BodyProvided=true and state.Body = opts.Body is applied after autofill, so the explicit body wins. This relies on gh's documented, stable --body/--body-file-overrides---fill precedence (verified against current gh), so it is a durable contract rather than a version snapshot. Implementation is correct against real gh, not just the fixture.
• The body prints the absolute Source spec path into the PR description. This is spec-mandated (AC2 "source spec path") and author-controlled, so it is intended rather than a leak; noting only for awareness.
• Verified firsthand: bash tests/devloop_test.sh passes all checks including ok - 100% project function coverage.
