v1.4.0 — Evidence quality

Released 20 July 2026.

Added

• Event-linked evidence records that preserve negative, delayed, and inconclusive outcomes.
• Threshold-boundary investigations with explicit brackets, blockers, and completion criteria.
• Fail-closed evidence adjudication rules, contradiction assessments, and deterministic release-readiness gates.
• Evidence-intelligence pressure scoring and seven bounded acquisition missions.
• Mission-specific intake, privacy screening, human review, conflict disclosure, and controlled dispositions.
• Non-executable promotion plans with exact impact previews, validation requirements, and rollback scope.
• Six-record public reconstruction corpus for Quickdraw, YOLO, and Pair Extraordinaire.
• GitHub-owned live achievement-fragment corpus with exact criteria, linked history, and normalized fingerprints.
• Complete first-party milestone histories for Pull Shark, Galaxy Brain, and Starstruck.
• Weekly live-fragment drift verification.
• Static API discovery expanded to forty public JSON files.

Changed

• Evidence coverage increased from 44.2 at the v1.3.0 baseline to 91.2/100 — Robust.
• Twelve of thirteen canonical claims are now official or confirmed.
• Only Pair Extraordinaire numerical tier thresholds remain below confirmed.
• Quickdraw's five-minute timing contract is now official.
• Pull Shark milestones are now officially documented as 2, 16, 128, and 1,024 merged pull requests.
• Galaxy Brain milestones are now officially documented as 2, 8, 16, and 32 accepted answers.
• Starstruck milestones are now officially documented as 16, 128, 512, and 4,096 repository stars.
• YOLO's broad contract is now officially documented as Merged without a review.
• Pair Extraordinaire's broad contract is now officially documented as coauthored commits on merged pull requests.
• Open contradictions reduced from six to three.

Corrected

• Replaced community-only milestone classifications where GitHub's live product fragments publish the exact contracts.
• Separated broad trigger certainty from unresolved edge cases, processing behaviour, transfer semantics, and attribution rewrites.
• Removed stale blocked-release wording after the merged-main evidence and operational gates passed.

Included work

• PR #232 — Phases 52–56: evidence quality programme
• PR #233 — Evidence intelligence dashboard
• PR #234 — Targeted evidence acquisition missions
• PR #235 — Mission execution intake and triage
• PR #236 — Mission packet review queue
• PR #237 — Mission evidence promotion planner
• PR #238 — Independent public reconstruction evidence
• PR #239 — GitHub-owned achievement contracts

Verification

Validated from merged main on 20 July 2026:

Gate	Verified	Required	Result
Evidence coverage	91.2	≥ 70.0	PASS
Official or confirmed claims	12	≥ 8	PASS
Claims below confirmed	1	≤ 5	PASS
Open contradictions	3	≤ 3	PASS
Operational health	100/100	100	PASS

• All permanent evidence, content, API, browser, visual, release, and repository-audit workflows passed.
• GitHub-owned fragment criteria and normalized fingerprints were re-fetched and verified live.
• Markdown, links, catalogue consistency, JSON contracts, Jekyll output, search routing, and visual baselines passed.
• The release is published from the merged release-note commit by the repository's verified immutable release workflow.

Known limitations

• Pair Extraordinaire numerical tier thresholds remain community-reported because GitHub's x4 detail fragment does not publish the counts.
• YOLO alternate review states and structured merger identity remain unresolved edge cases.
• Pair Extraordinaire squash, rebase, email-mismatch, and rewritten-history behaviour remains unresolved.
• Starstruck repository transfer, organisation ownership, forks, archival, falling counts, and persistence remain unresolved.
• Achievement processing and profile visibility may still be delayed independently of a qualifying event.
• Public product fragments can change; the weekly monitor fails closed on criterion or fingerprint drift.

v1.3.0 — Evidence operations

Released 19 July 2026.

Added

• Claim-level evidence ownership with zero unassigned weak claims.
• Twelve-task contributor research queue and deterministic priority ranking.
• Five privacy-safe reproduction protocols for the highest-value active research areas.
• Automated evidence issue triage with prohibited-data screening.
• Draft evidence-record and draft pull-request creation after passing screening.
• Read-only public-signal profile auditor.
• Public research command centre.
• Expanded API discovery covering twenty-five public JSON files.
• Dedicated evidence-operations validation workflow.

Verification

• Research-intelligence generator validates thirteen claims and six contradiction records.
• Evidence-operations generator validates twelve tasks, five protocols, nine auditor rules, and the submission schema.
• Weak claims without assigned research are rejected.
• Generated API drift is checked.
• Evidence submissions remain subject to mandatory human review.
• Repository operational health was verified at 100/100 — Excellent before release preparation.

Known limitations

• Evidence coverage remains 44.2/100 until independent observations strengthen the underlying claims.
• The profile auditor analyses public signals and cannot detect badge visibility.
• Unauthenticated GitHub API requests are rate-limited and omit private activity.
• Automated privacy screening reduces risk but cannot guarantee that user-submitted text is safe.
• Draft evidence pull requests do not alter canonical evidence until a maintainer reviews and merges them.

GitHub Achievement Encyclopedia v1.2.0

GitHub Achievement Encyclopedia v1.2.0

Validation date: 19 July 2026
Release type: Research infrastructure and maintenance release
Release target: main

This release makes the encyclopedia's supporting research traceable, monitorable, and contributor-ready while preserving the evidence model and public API introduced in earlier releases.

Added

• A privacy-safe public evidence register containing one baseline record for every canonical achievement.
• A machine-readable evidence endpoint with claim, classification, dates, reproduction status, reviewer decision, privacy status, limitations, and guide location.
• A weekly monitor for six official GitHub documentation pages using normalized visible-content fingerprints.
• Automatic review-issue creation when a scheduled monitor detects a material official-document change.
• Nine achievement verification timelines with page-level last-reviewed dates and explicit history gaps.
• A contributor research hub containing eight bounded research tasks and three good-first research opportunities.
• A structured research issue form requiring methods, dated results, limitations, and privacy declarations.
• Static API endpoints for evidence records, timelines, and the contributor research queue.

Changed

• The authoritative repository audit now executes 17 controls instead of 12.
• Public API discovery now identifies evidence, timeline, and research-queue endpoints.
• GitHub Actions references were upgraded where applicable and pinned to immutable commit SHAs.
• Repository navigation and the flagship documentation expose the complete research lifecycle.

Verification

The release candidate must pass:

1. Repository-wide Markdown validation.
2. Achievement catalogue consistency.
3. Achievement data contract.
4. Verification-date freshness.
5. Public evidence-register alignment and generated-output drift.
6. Achievement verification-timeline chronology and coverage.
7. Contributor research-queue references and acceptance criteria.
8. Official GitHub documentation baseline integrity.
9. Full repository link validation.
10. External-source resilience inventory generation.
11. Public API discovery and endpoint drift validation.
12. Repository health generation.
13. Site metadata and accessibility contract.
14. Semantic-version release-policy compliance.
15. Production GitHub Pages build.
16. Browser search behaviour.
17. Desktop and mobile visual regression.

Release publication occurs only after the merged main commit passes the formal release workflow. The v1.2.0 tag must resolve to that exact merge commit.

Known limitations

• GitHub still does not publish complete rules or tier thresholds for every achievement.
• Several research tasks remain open because independent reproduction has not yet met the target evidence level.
• Official-document fingerprints detect textual change but require human interpretation before guide claims are modified.
• The evidence register begins with one baseline record per achievement; it does not yet represent every historical observation.
• Year-only historical timeline entries deliberately avoid asserting unsupported exact dates.

Included programme

• Phase 34 — dependency and CI hardening.
• Phase 35 — public evidence register.
• Phase 36 — official GitHub documentation monitor.
• Phase 37 — achievement verification timelines.
• Phase 38 — contributor research hub.
• Phase 39 — expanded audit, API discovery, and formal release.

GitHub Achievement Encyclopedia v1.1.0

GitHub Achievement Encyclopedia v1.1.0

Validation date: 19 July 2026
Release type: Feature and public-data release
Release target: main

This release turns the verified encyclopedia into an operationally observable, searchable, and machine-consumable reference while preserving the evidence classifications established in v1.0.0.

Added

• A generated repository health dashboard with workflow, freshness, source, release, and backlog state.
• A validated nine-record achievement dataset and JSON Schema draft 2020-12 contract.
• An accessible search and filtering interface covering achievements and core project references.
• A single-command repository audit with consolidated Markdown and JSON evidence.
• A static public data API containing discovery, aggregate, individual achievement, schema, and health endpoints.
• Browser tests for aliases, combined filters, project-base routing, and accessible result announcements.

Changed

• Search now uses exact token and alias matching, preventing short terms such as PR from matching unrelated words.
• Generated search links preserve the /Achievements GitHub Pages base path.
• Repository navigation exposes search, health, audit, dataset, schema, and API surfaces.
• Formal release verification now runs the unified repository audit and public API drift validation.
• Markdown and link audits explicitly exclude installed third-party dependencies and generated evidence directories.

Verification

The release candidate must pass all of the following controls before merge:

Control	Release criterion
Unified repository audit	All 12 controls pass in one command
Public API	Generated index, aggregate, schema, and nine individual endpoints match the canonical dataset
Health endpoint	api/status.json exists and identifies the correct repository
Achievement data	Nine unique records match index, guides, permalinks, and verification dates
Search behaviour	Alias, status, tier, reference, routing, and accessibility assertions pass in Chromium
Markdown and links	Repository-owned files pass complete validation
Source resilience	Inventory generation passes
GitHub Pages	Production Jekyll build succeeds
Visual regression	Ten desktop and mobile baselines match
Release metadata	Version, date, scope, included work, and limitations are recorded

API endpoint set

• /Achievements/api/index.json
• /Achievements/api/achievements.json
• /Achievements/api/achievements/{slug}.json
• /Achievements/api/schema.json
• /Achievements/api/status.json

Included work

• PR #216 — repository health dashboard.
• PR #217 — machine-readable achievement dataset.
• PR #218 — advanced search and filtering.
• PR #219 — unified repository self-audit.
• PR #220 — public API, release integration, and v1.1.0 publication.

Known limitations

• The API is a static GitHub Pages publication. It does not provide server-side queries, authentication, mutation, pagination, or guaranteed response-time service levels.
• status.json reflects the latest completed health-dashboard refresh and can briefly lag behind repository activity.
• Search requires client-side JavaScript; the achievement index remains the non-JavaScript fallback.
• GitHub does not publish complete official trigger and tier specifications for every achievement. API delivery does not strengthen community-reported evidence.
• Consumers must retain evidence classifications, verification dates, and known limitations when presenting achievement data.
• Automated source availability can be affected by rate limiting, access controls, bot protection, or transient outages.
• Visual regression covers representative pages and does not replace manual accessibility or editorial review.

Maintenance baseline

Future compatible endpoint additions follow minor-version releases. Breaking API envelopes or achievement data fields require major version changes to the applicable version field. Evidence changes continue to follow the maintenance policy, release policy, and verification methodology.

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.
