GitHub Achievement Encyclopedia v1.0.0
GitHub Achievement Encyclopedia v1.0.0
Validation date: 19 July 2026
Release type: First formal verified baseline
Release target: main
This release records the first stable, tagged baseline of the GitHub Achievement Encyclopedia. It covers the complete canonical catalogue, the evidence and governance model, the public GitHub Pages presentation, and the repository's automated quality controls.
Added
- Nine standardised achievement guides: seven active and two retired.
- Evidence-strength classifications and a reproducible verification methodology.
- Repository-wide Markdown, catalogue, link, metadata, accessibility, and Jekyll validation.
- Automated verification-date freshness reporting for every canonical guide.
- External source resilience inventories in CSV and Markdown formats.
- Desktop and mobile visual-regression baselines for five representative pages.
- Maintenance, release, dependency, and recurring verification policies.
- A flagship repository README and accessible SVG identity.
Changed
- Repositioned the repository as an evidence-led encyclopedia rather than an achievement-unlocking checklist.
- Established the catalogue-linked guides as the canonical release scope.
- Replaced changed-file-only Markdown validation with a complete repository baseline.
- Adopted semantic versioning for tagged releases in accordance with the release policy.
Corrected
- Resolved the Markdown debt exposed by repository-wide validation.
- Repaired internal routes identified during the full baseline audit.
- Added missing verification-date sections to active canonical guides.
Verification
The release candidate must pass all of the following controls before merge:
| Control | Release criterion |
|---|---|
| Canonical catalogue | Exactly nine guides are present in the index and navigation hub |
| Verification freshness | Nine Fresh; zero Due soon, Overdue, or Invalid |
| Markdown | Every tracked Markdown document passes the configured baseline |
| Links | Full repository internal-link validation passes |
| Jekyll | GitHub Pages production build succeeds |
| Source inventory | CSV and Markdown inventories generate successfully |
| Visual regression | Ten desktop and mobile screenshots match the committed baseline |
| Release metadata | Version, validation date, scope, limitations, and included work are recorded |
Included work
This baseline consolidates the completed programme and its final hardening phases:
- PR #198 — repository-wide link baseline validation.
- PR #199 — accessibility improvements and audit evidence.
- PR #200 — deployment metadata validation.
- PR #201 — catalogue consistency enforcement.
- PR #202 — maintenance policy.
- PR #203 — release and version policy.
- PR #204 — recurring verification calendar.
- PR #205 — contributor review checklist.
- PR #206 — controlled dependency maintenance.
- PR #208 — programme completion record.
- PR #209 — flagship README redesign.
- PR #210 — repository-wide Markdown quality baseline.
- PR #212 — verification-date reporting.
- PR #213 — source resilience inventory.
- PR #214 — visual regression baseline.
- Phase 28 release pull request — formal verification report, changelog reconciliation, release gate, tag, and GitHub Release.
Known limitations
- GitHub does not publish complete official trigger or tier specifications for every achievement. Community-reported values remain labelled and are not presented as guaranteed platform contracts.
- Achievement processing delays, private-repository behaviour, rewritten history, visibility settings, regional eligibility, and other edge cases are not comprehensively documented by GitHub.
- Availability checks can be affected by authentication, rate limiting, bot protection, or transient outages; an automated failure is diagnostic rather than conclusive evidence that a source is invalid.
- Visual comparison detects rendering changes in the selected representative pages; it does not replace manual accessibility or content review.
Maintenance baseline
Future material changes follow semantic versioning, the maintenance policy, and the verification calendar. Claims must retain their evidence classification and verification date when GitHub behaviour changes.
