This guide only claims what is in the public repo. Several production pieces are missing on purpose. We do not invent them.

<aside> ✅

What they published

The shape of the pipeline. How many posts each door can send. The filter order. The scoring weights (mirrored 12 August 2026). Author diversity. The stranger tax. The small-account bump. The safety rule families. Twenty Scarecrow bots. Grox plan names. Phoenix’s architecture — not its trained numbers.

<aside> 🚫

What they did not

Grox’s actual prompts. Some rule files. Phoenix’s live weights and indexes. The ads auction. The follow-graph store. How your action history is built. Several severity cutoffs (blanked as 9.99). What a blur looks like on screen. The live retrieval server.

</aside>

If a tactic is not in the published list, it is not a claim here. “Post at 9am” and “short sentences rank higher” are the usual examples.
