Findings

Rule	Count	Representative message
shelldre:S7682	4	Add an explicit return statement at the end of the function.
shelldre:S1192	1	Define a constant instead of using the literal 'missing' 6 times.

Affected files

scripts/apply-repo-settings.test.sh (4)
scripts/apply-repo-settings.sh (1)

Priority

Labeled priority:major — mapped from this bucket's worst SonarCloud severity (MAJOR).

Acceptance

All findings in this workstream resolved to zero in SonarCloud
No behavior change; CI green
Real fixes (no blanket NOSONAR unless a confirmed false positive, noted inline)

Idempotent issue — updated automatically each audit run; auto-closed when the finding count reaches zero.

Dev-Lead Implementation Plan

Issue: #349 — SonarCloud: shell script hygiene

Scope

Resolve the 4 shelldre:S7682 findings ("Add an explicit return statement at the end of the function") by adding explicit return statements to the shell functions that currently contain none — a behavior-preserving hygiene change.

Analysis

S7682 fires on functions that contain no explicit return statement anywhere. Matching the reported counts:

scripts/apply-repo-settings.test.sh (3): pass, fail, assert_eq — none contain a return.
scripts/apply-repo-settings.sh (1): apply_security_and_analysis — the only main-script function with no return. The other three (resolve_repo, auto_trigger_status, apply_check_suite_prefs) already contain return statements and are compliant.

Implementation Checklist

scripts/apply-repo-settings.sh — add bare return at end of apply_security_and_analysis (bare return propagates the gh api exit status, preserving set -e behavior in main)
scripts/apply-repo-settings.test.sh — add explicit return at end of pass, fail, assert_eq

Tests to Write

No new tests. This is a behavior-preserving refactor (no observable behavior change), so the Phase 2 TDD exception applies. The existing unit tests in apply-repo-settings.test.sh will be run to confirm no regression.

Test Command

bash scripts/apply-repo-settings.test.sh plus bash .dev-lead/scripts/dev-lead-lint.sh

Dev-Lead: Implementation Complete

Plan Execution

Analyzed the 4 shelldre:S7682 findings — the rule fires on functions containing no explicit return statement. Identified the exact functions: apply_security_and_analysis (main, 1) and pass/fail/assert_eq (test, 3).
Added a bare return at the end of apply_security_and_analysis in scripts/apply-repo-settings.sh.
Added an explicit return at the end of pass, fail, and assert_eq in scripts/apply-repo-settings.test.sh.
Verified unit tests, dev-lead-lint.sh, and shellcheck all pass.
Rubber-duck review of full diff — behavior preserved, only the non-compliant functions touched.

Why bare `return` (behavior-preserving)

A bare return returns the exit status of the last command executed in the function. For apply_security_and_analysis this propagates the gh api exit status, exactly matching the prior implicit return so set -euo pipefail in main still aborts on API failure. The three test helpers likewise keep their last-command status, so no test outcome changes.

Test Results

ok   - auto_trigger_status: enabled app -> true
ok   - auto_trigger_status: disabled app -> false
ok   - auto_trigger_status: app absent -> missing

Files Changed

scripts/apply-repo-settings.sh: added return at the end of apply_security_and_analysis (1 finding).
scripts/apply-repo-settings.test.sh: added return at the end of pass, fail, assert_eq (3 findings).

Notes

TDD Phase 2 exception: This is a behavior-preserving hygiene refactor with no observable behavior change, so no new tests were written. The existing unit tests were run before and after and remain green.
The other main-script functions (resolve_repo, auto_trigger_status, apply_check_suite_prefs) already contain return statements and were left untouched — consistent with the finding count of 1 for apply-repo-settings.sh.
No NOSONAR suppressions used; all fixes are real explicit returns.

Dev-Lead Implementation Plan

Issue: #349 — SonarCloud: shell script hygiene

Scope

Resolve 5 SonarCloud shell findings (behavior-preserving): define a constant for the duplicated 'missing' literal in apply-repo-settings.sh (S1192) and add explicit return statements to the helper functions in apply-repo-settings.test.sh (S7682).

Implementation Checklist

scripts/apply-repo-settings.sh — add readonly STATUS_MISSING='missing' and replace all 6 code occurrences of the literal (2× printf, 1× case pattern, 3× inside jq programs threaded via --arg missing)
scripts/apply-repo-settings.test.sh — add an explicit return 0 at the end of pass(), fail(), and assert_eq()

Tests to Write

No new tests — this is a behavior-preserving refactor. The existing portable test suite (scripts/apply-repo-settings.test.sh, 15 assertions) is the regression guard and must stay green (asserts the "missing" sentinel is unchanged).

Test Command

bash scripts/apply-repo-settings.test.sh (plus bash .dev-lead/scripts/dev-lead-lint.sh for shellcheck)

Dev-Lead: Implementation Complete

Plan Execution

scripts/apply-repo-settings.sh — S1192: added readonly STATUS_MISSING='missing' and replaced all 6 code occurrences of the literal (2× printf, 1× case pattern, 3× inside jq via --arg missing). The literal now appears exactly once (the constant definition).
scripts/apply-repo-settings.test.sh — S7682: added explicit return 0 to pass(), fail(), and assert_eq().

Files Changed

scripts/apply-repo-settings.sh: define STATUS_MISSING constant; use it in the two printf fallbacks, the case pattern, and both jq programs (threaded via --arg missing) — resolves S1192.
scripts/apply-repo-settings.test.sh: explicit return 0 at the end of pass, fail, assert_eq — resolves S7682.

Notes

No behavior change. printf '%s' "$STATUS_MISSING" and the jq $missing arg produce identical output to the former literals; verified the sentinel-emitting paths still return missing and the variable case pattern matches literally (no glob metacharacters). All 15 existing assertions stay green — this is the regression guard.
TDD note: Phase 2 skipped per the behavior-preserving-refactor exception; the existing portable test suite already covers the sentinel behavior and validates equivalence.
S7682 count: the audit reported 4 occurrences, but the test file defines exactly 3 functions (pass, fail, assert_eq) — all three now have explicit returns. No 4th function exists (likely a stale/duplicate count); the next audit scan should confirm zero.
The main-script helper functions (apply_*, status helpers) were intentionally not given blanket return 0 — they end with gh api/jq/printf whose exit status is meaningful, and masking it would be a behavior change. Per the audit breakdown, S7682 does not fire on those.

Dev-Lead Implementation Plan

Issue: #349 — SonarCloud: shell script hygiene

Scope

Resolve 5 SonarCloud shell findings (4× S7682 explicit-return, 1× S1192 duplicated 'missing' literal) with behavior-preserving fixes. Ground-truth from the SonarCloud API refined the exact locations (the issue's file table was slightly off).

Exact findings (SonarCloud API)

S7682 — add explicit terminal return:
- scripts/apply-repo-settings.test.sh:15 (pass)
- scripts/apply-repo-settings.test.sh:19 (fail)
- scripts/apply-repo-settings.test.sh:25 (assert_eq)
- scripts/apply-repo-settings.sh:71 (apply_security_and_analysis)
S1192 — scripts/apply-repo-settings.test.sh:68: literal "missing" used 6× → extract a constant.

Implementation Checklist

scripts/apply-repo-settings.test.sh: add return 0 to pass, fail, assert_eq
scripts/apply-repo-settings.test.sh: define readonly MISSING='missing' and use it for the 6 expected-value assertions
scripts/apply-repo-settings.sh: add bare return to end of apply_security_and_analysis (preserves gh api exit status under set -e)

Tests to Write

Behavior-preserving refactor: the existing suite scripts/apply-repo-settings.test.sh is the regression guard (15 assertions, currently green). No new behavior to add, so per the protocol's refactor exception no new failing test is written; the suite must stay green before and after.

Test Command

bash scripts/apply-repo-settings.test.sh (plus repo lint: bash .dev-lead/scripts/dev-lead-lint.sh)

Dev-Lead: Implementation Complete

Resolved all 5 SonarCloud shell findings with behavior-preserving fixes. Note: I pulled the exact finding locations from the SonarCloud issues API — the issue's "Affected files" table was slightly off (it attributed all 4 S7682 to the test file and the S1192 to the main script; in reality S1192 is in the test file at line 68, and one S7682 is in the main script at line 71).

Plan Execution

S1192 — extracted readonly MISSING='missing' in apply-repo-settings.test.sh and used it for all 6 expected-value assertions
S7682 — added return 0 to pass, fail, assert_eq in apply-repo-settings.test.sh
S7682 — added bare return to apply_security_and_analysis in apply-repo-settings.sh (preserves the gh api exit status under set -e; return 0 would have masked failures)

Test Results

$ bash scripts/apply-repo-settings.test.sh
ok   - auto_trigger_status: enabled app -> true
ok   - auto_trigger_status: disabled app -> false
ok   - auto_trigger_status: app absent -> missing

Files Changed

scripts/apply-repo-settings.test.sh: added readonly MISSING constant + used it in 6 assertions (S1192); added explicit return 0 to pass/fail/assert_eq (S7682)
scripts/apply-repo-settings.sh: added bare return at the end of apply_security_and_analysis (S7682)

Notes

Behavior-preserving refactor — no observable behavior change. Per the protocol's refactor exception, no new failing test was written; the existing 15-assertion suite is the regression guard and stays green.
The bare return (vs return 0) in apply_security_and_analysis is intentional: it returns $? of the gh api call so a failing API call still aborts main under set -e.
Only the 4 functions SonarCloud actually flagged for S7682 were touched; the other helpers already contain explicit return statements and were not flagged, so they were left unchanged.
