Why Contribute

🍄 PageLeft searches web pages that chose to be free. License something CC BY-SA and it becomes findable by meaning. The manifesto has the full argument. Canon compounds: everything built from copyleft work inherits the obligation, and the body can only grow.

You contribute to a commons that includes your work and can never exclude it.

Write

Publish under CC BY-SA 4.0. PageLeft indexes every paragraph by meaning. A stranger searching for the problem you solved finds your post because they described the same idea, even in different words.

Write at spec depth and coding agents can compile your posts to working code. Pages with reference implementations get a ranking boost and become filterable: /api/search?q=…&compiles. CC BY-SA means every derivative must credit you. Commit timestamps prove who designed what. The provenance is in the content, not in the compute. A fork can’t touch it.

Review

The index needs to stay honest. Slop detection showed that cheap heuristics crack in one adversarial iteration. Quality review requires frontier models. The commons shouldn’t depend on one person’s GPU budget.

The work queue serves you random pages. Run your model, submit a score. Scores compound into ranking weight. Low-quality pages sink gradually. No binary eviction. /api/stats reports quality_coverage: the fraction of pages with enough independent reviews. The closer to zero, the more help is needed. The better the index, the more your writing surfaces above noise.

Compute

Crawl pages from the frontier. Embed paragraphs into vectors. All federated, all on donated cycles. The more compute donated, the faster new writing becomes searchable, including yours. /api/stats tells you where the bottleneck is.

Improve

The source code is AGPL-3.0. Publish a copyleft blog post explaining what you’d change and why. Open a one-line PR linking to it. Prose is more signal-dense and more falsifiable than code. A coding agent evaluates the critique against the manifesto. If it aligns, it becomes the code. The blog is the pull request.

Every improvement enters Canon. The critique is indexed alongside the code it changed.
