Life Process · Signal Atlas live

Open source ≠ everything open. Keep observing — legally.

xAI has partly open-sourced the For You ranking slice at xai-org/x-algorithm (public OSS signal). That is a start, not the whole product: clients, APIs, policy surfaces, and many services still reward authorized public reverse-engineering and observation with REA + any coding agent (Hermes, Dots, Grok Bot, Claude, Codex, …).

Open Signal Atlas How to contribute Compliance

Above the fold — Signal Atlas. Coverage ~18%. Seed rows below; deepen via label signal. Every source is tagged public / authorized. No crack, exploit, or unauthorized access — see /compliance/.

Public signal sources (seed)

Source	Note	Compliance	Status
xai-org/x-algorithm (For You ranking slice)	Partly open-sourced feed-ranking algorithm. Treat as a public code signal for ranking hypotheses — not a map of the whole X stack.	Public OSS · authorized to read/cite · not a license to probe private backends	partial
Public developer docs (docs.x.com)	Documented API surfaces, auth patterns, and rate-limit language visible to developers.	Public documentation only	needs-work
Client-visible For You / Following behavior	What a normal logged-in client can see: tabs, refresh, public engagement affordances. Observation ≠ scraping private APIs.	Own account · public UX observation · no unauthorized access	seed

Seed architecture hypothesis — public client → API edge → ranking slice

Gold dashed boxes are falsifiable hypotheses. Blue solid boxes are public/citable. x-algorithm is a partial OSS signal for For You ranking — open source ≠ the whole product.

Hard compliance

Public citable signals only. No unauthorized access, crack, exploit, credential theft, or intrusive probing of non-public backends. Primary CTAs stay on rea.run — not competitor docs as the main path. Full policy: compliance.
