[jsweep] Clean action_setup_otlp.cjs

[github-actions]

Summary

Cleaned actions/setup/js/action_setup_otlp.cjs by extracting a writeEnvLine helper to DRY up the six repetitive appendFileSync + console.log call-pairs that wrote trace/span IDs to GITHUB_OUTPUT and GITHUB_ENV.

Context

Execution context: Pure Node.js (invoked from actions/setup/index.js and setup.sh) — console.log is the correct output method here.

Changes

• Extracted writeEnvLine(filePath, key, value, logLabel) helper that guards on filePath and value, appends the key=value\n line, and logs [otlp] <logLabel> written to GITHUB_OUTPUT|GITHUB_ENV.
• Replaced 6 repetitive if (...) { appendFileSync(...); console.log(...); } blocks with single-line writeEnvLine(...) calls.
• Captured githubOutput / githubEnv into local const variables to avoid repeated process.env lookups.
• No logic changes — behaviour is identical.

Type Checking

File already had @ts-check (not @ts-nocheck). Added JSDoc for the new writeEnvLine helper. All type errors: none.

Test Coverage

Existing test file already has 39 comprehensive tests covering:

• OTLP endpoint present / absent
• SETUP_START_MS valid / invalid / missing variants (6 cases)
• INPUT_TRACE_ID normalization, fallback form, preference (8 cases)
• INPUT_JOB_NAME normalization
• GITHUB_OUTPUT writes (5 cases)
• GITHUB_ENV writes (8 cases)
• Error propagation

No additional tests needed — coverage is already thorough.

Validation

• Formatting: npx prettier --check action_setup_otlp.cjs ✅
• Type checking: npx tsc --noEmit ✅
• Tests: npx vitest run action_setup_otlp.test.cjs — 39/39 passed ✅

Pull request overview

This PR refactors OTLP setup output/env file writes by extracting a small helper to reduce repeated append-and-log blocks without changing behavior.

Changes:

• Added writeEnvLine(...) helper for GitHub Actions file writes.
• Replaced repeated appendFileSync/console.log blocks with helper calls.
• Cached GITHUB_OUTPUT and GITHUB_ENV environment values locally.

Skills-Based Review 🧠

Applied /zoom-out and /improve-codebase-architecture — this is a clean refactor/cleanup PR with no behaviour changes.

Key Themes

• Shallow helper abstraction: writeEnvLine re-inspects process.env.GITHUB_OUTPUT to decide between "GITHUB_OUTPUT" and "GITHUB_ENV" in its log message, leaking the caller's domain back into the helper. The deletion test passes — the helper earns its keep — but its interface can be deepened by removing this reverse-lookup.
• Inconsistent logLabel usage: GITHUB_OUTPUT call sites embed the value in the label (trace-id=${traceId}) while GITHUB_ENV call sites only pass the key name. Uniform format would make log scanning easier.

Positive Highlights

• ✅ Excellent DRY improvement — 6 copy-pasted if/appendFileSync/console.log blocks reduced to single-line calls
• ✅ JSDoc with typed parameters is a nice addition
• ✅ Capturing githubOutput / githubEnv as local const is the right instinct for repeated env lookups
• ✅ String(Math.floor(nowMs())) ensures type safety with the {string} value contract
• ✅ 39 existing tests all still pass — no regression risk

Verdict

Approving — both suggestions above are non-blocking improvements to polish an already solid refactor.

The automated Copilot review (@copilot-pull-request-reviewer) already ran on this PR and found 0 issues — no comments were generated. The code review confirms the refactoring is clean: the extracted writeEnvLine helper correctly preserves all original behavior, the guard conditions (!filePath || !value) are safe, and the GITHUB_OUTPUT/GITHUB_ENV label logic in the log message is accurate.
