Briancl2 Customernewsletter Scope Contract

Scope Contract

Generate a testable scope manifest before the pipeline runs, then validate the newsletter output against it after assembly.

Quick Start

Pre-Pipeline (Phase 0)

1. Read DATE_RANGE and kb/SOURCES.yaml
2. Check archive/ for previous newsletter end date (verify no gaps)
3. Generate scope manifest: expected versions, sources, categories
4. Write to workspace/newsletter_scope_contract_YYYY-MM-DD.json

Post-Pipeline (after Phase 4.5)

1. Read scope manifest
2. Read final newsletter
3. Run validation checks
4. Write test results to workspace/newsletter_scope_results_YYYY-MM-DD.md

Pre-Pipeline Workflow

Step 1: Determine Date Range Boundaries

1. Read the requested DATE_RANGE (start, end)
2. Find the previous newsletter in archive/ by examining filenames
3. Determine the previous newsletter's coverage end date (from its content or filename)
4. Calculate gap: if start - previous_end > 1 day, flag the gap and recommend extending start date
5. Record in manifest

Step 2: Determine Expected Versions

For each IDE source in kb/SOURCES.yaml:

1. Read latest_known.version and latest_known.release_date
2. Determine which versions fall within DATE_RANGE
3. For VS Code: MUST fetch code.visualstudio.com/updates index page and parse every version's actual release date. VS Code ships weekly releases (L66), so a 30-day range typically includes 4-5 versions; a 60-day range includes 8-10. List ALL versions whose actual release date falls within DATE_RANGE. Do NOT rely on SOURCES.yaml latest_known alone -- it only has the newest version.
4. For JetBrains: check API for releases within DATE_RANGE (cdate field)
5. For Xcode: check releases page for versions within DATE_RANGE
6. Record all expected versions in manifest

GATE: The vscode list MUST contain >=4 entries for any DATE_RANGE spanning 30+ days (weekly cadence), or explicitly document why fewer exist (e.g., holiday weeks). If only 1-2 versions are listed, re-check the updates index page.

Step 3: Enumerate Expected Sources

List every URL that MUST be checked based on SOURCES.yaml and the date range:

• GitHub Changelog monthly archives for each month in range
• GitHub Blog news-insights page
• VS Code release notes for each expected version
• Visual Studio release notes / devblogs
• JetBrains plugin API
• Xcode releases
• Events pages

Step 4: List Expected Categories

All standard newsletter categories. Mark any that had zero items in the previous newsletter (higher scrutiny).

Step 5: Write Manifest

Write the JSON manifest to workspace/newsletter_scope_contract_YYYY-MM-DD.json.

Post-Pipeline Validation

Check 1: Date Range Coverage

• All items in the newsletter are within DATE_RANGE
• No items from versions prior to the expected range
• No date gap with previous newsletter (or gap was explicitly closed)

Check 2: Version Coverage

• Every expected VS Code version is mentioned
• Every expected JetBrains version range is covered
• Expected Xcode versions are mentioned
• Visual Studio update is mentioned
• CLI updates are mentioned

Check 3: Source Coverage

• GitHub Changelog items present
• GitHub Blog/news-insights items present (if any existed in date range)
• VS Code release notes deep-read content present
• JetBrains granular version content present
• Xcode content present
• Events from events page present

Check 4: Category Coverage

• Each expected category has at least 1 item OR is explicitly noted as "no updates in scope"
• No category silently omitted

Check 5: Event Date Range

• All events are within a reasonable future window (not past events, not >6 months out)
• Events sorted chronologically

Check 6: Structural Integrity

• Run validate_newsletter.sh -> 0 errors
• Line count in expected range
• All links resolve to expected domains

Output

Pre-Pipeline

• workspace/newsletter_scope_contract_YYYY-MM-DD.json

Post-Pipeline

• workspace/newsletter_scope_results_YYYY-MM-DD.md with:
  • Pass/Fail per check
  • Missing items list
  • Out-of-scope items list
  • Recommended fixes

Done When

Pre-Pipeline:

• Scope manifest exists with all fields populated
• Date range gap flagged if present
• Expected versions listed for all 5 IDE sources

Post-Pipeline:

• All 6 checks evaluated
• Results file written
• Any failures documented with specific fix recommendations
