Category breakdown

Impact

25% weight

24F

The project themes cover current software topics and practical tools, but the available metadata does not demonstrate original implementation, usefulness, or distinctive outcomes.

Consistency

15% weight

28F

The supplied repositories show activity from 2019 through 2023, but all listed projects are forks and there is no contribution-total evidence establishing sustained original activity.

Quality

25% weight

25F

Repository names span recognizable technical subjects, yet all listed entries are marked as forks and no source, tests, CI, documentation, or architecture evidence is available for evaluating engineering maturity.

Depth

20% weight

20F

The listed set contains multiple technically varied projects, but fork status and the absence of implementation or maintenance details provide weak evidence of sustained ownership or meaningful scope.

Breadth

10% weight

38F

The portfolio covers AI, retrieval, notebooks, system design, security, web/PWA, OCR, operating-system setup, and Python learning material, although language metadata is unavailable and ownership appears limited.

Community

50D

Follower and star data provide limited signal; community evidence is treated as a neutral tie-breaker, with no popularity-based penalty.

Impact · 24/100

What it measures. Project usefulness, ambition, originality, and coherence. Popularity is not impact.

Evidence for roberval. The project themes cover current software topics and practical tools, but the available metadata does not demonstrate original implementation, usefulness, or distinctive outcomes.

Quality · 25/100

What it measures. Engineering and project-maturity signals supported by the available public metadata.

Evidence for roberval. Repository names span recognizable technical subjects, yet all listed entries are marked as forks and no source, tests, CI, documentation, or architecture evidence is available for evaluating engineering maturity.

Depth · 20/100

What it measures. Sustained ownership, meaningful scope, and continued maintenance rather than one-shots.

Evidence for roberval. The listed set contains multiple technically varied projects, but fork status and the absence of implementation or maintenance details provide weak evidence of sustained ownership or meaningful scope.

Consistency · 28/100

What it measures. Recency and contribution patterns across the supplied activity window.

Evidence for roberval. The supplied repositories show activity from 2019 through 2023, but all listed projects are forks and there is no contribution-total evidence establishing sustained original activity.

Breadth · 38/100

What it measures. Language entropy and project-type diversity across owned repos.

Evidence for roberval. The portfolio covers AI, retrieval, notebooks, system design, security, web/PWA, OCR, operating-system setup, and Python learning material, although language metadata is unavailable and ownership appears limited.

Community · 50/100

What it measures. A weak positive tie-breaker for supplied community signals, never a popularity penalty.

Evidence for roberval. Follower and star data provide limited signal; community evidence is treated as a neutral tie-breaker, with no popularity-based penalty.

I. How this saved profile rating was produced

  1. 01

    Validate. The server validates the login, signed browser session, attempts, cooldown, daily ceiling, and the single provider permit.

  2. 02

    Collect. The VPS collector reads bounded public profile metadata and up to 12 recent repository metadata rows in volatile memory.

  3. 03

    Rate. One pinned provider returned a closed profile-rating object with no tools, browsing, shell, or repository-content access.

  4. 04

    Verify. Server checks bound the subject, rejected unsafe or echoed text, validated the schema, and recomputed rubric-v3 final arithmetic.

  5. 05

    Save. Only a valid completion and allowlisted post-completion facts commit atomically; the public projection is then rebuilt.

This saved profile analysis is metadata-only and did not read repository trees, README files, or source code. Availability of new analysis is separate from this historical result.

II. Data sources & caveats
  • Scores summarize one accepted, subject-bound analysis; they are not a security audit or endorsement.
  • Rank, percentile, and median use 1095 currently accepted public profiles and can change as the leaderboard changes.
  • Repository and language details reflect the bounded analyzed sample, not necessarily every repository.
  • Missing data is shown as unavailable or not evaluated instead of being inferred as zero.
  • Analysis completed Aug 10, 2026, 1:19 AM UTC and is marked aging.
