Structured workflows for author preparation, reviewer turnarounds, PR templates, merge gates, and regulated audit trails.

Predictable Review Rituals: Reducing Friction and Guaranteeing Traceability

A high-velocity pull request process rests on clear role division: authors take ownership of small, self-reviewed diffs with clear context, while reviewers commit to 24-hour turnaround SLAs with actionable, constructive feedback. In regulated systems, the pull request description and conversation thread form permanent compliance records proving that changes were verified by independent peers.

Author Quick-Start & Responsibilities

  • Keep Diffs Small (<400 LOC): Split large epics into vertical slices or stackable PRs behind feature flags.
  • Perform Self-Review First: Read your own diff on GitHub/GitLab before assigning reviewers to catch obvious typos, leftover debug logs, and missing comments.
  • Provide Context & Links: Fill out the PR template completely; link Jira tickets and SRS requirement IDs.
  • Respond Constructively: Acknowledge reviewer suggestions with gratitude; explain technical tradeoffs without defensiveness.

Reviewer Quick-Start & Responsibilities

  • 24-Hour Review SLA: Review assigned PRs within one business day or notify the author asynchronously if blocked.
  • Be Specific & Actionable: Offer concrete code alternatives and cite guidelines rather than vague criticisms.
  • Approve When Good Enough: Do not block a safe, functional change in pursuit of perfection. Prefix non-blocking ideas with (nit).
  • Inquire Rather Than Demand: Ask questions to understand the author's perspective before suggesting alternatives.

Standardized Pull Request Markdown Templates

Consistent PR templates ensure that every change carries requirement traceability, test verification evidence, and security sign-offs. Choose between the Standard Feature template and the Emergency Hotfix template below:

### 📋 Summary of Changes
- **Work Item / Jira**: [PROJ-1234](https://jira.example.com/browse/PROJ-1234)
- **SRS / Requirement Link**: SRS-SEC-042 (Session Invalidation)
- **Type of Change**: `Feature` | `Enhancement` | `Refactor`

#### Description
Clear 2–3 sentence overview of what this change accomplishes and the architectural rationale behind this approach.

Regulated Environment Documentation Checklist

FDA 21 CFR §820 / ISO 13485 Mandate

Prior to merging into protected release branches (e.g. main or release/*), automated branch protection rules and peer sign-offs must verify all four audit criteria:

1. Requirement Linkage

PR links directly to Jira ticket and SRS requirement ID, providing two-way traceability.

2. Comment Preservation

Zero deletion of review discussion threads; all review feedback remains permanently in repo history.

3. Segregation of Duties

Author cannot approve their own PR; minimum of 1 independent qualified peer sign-off required.

4. Timestamped Audit Trail

Cryptographic commit signing (GPG/SSH) and immutable merge commit timestamp recorded in DHF.
