Starlight · Gravity Engine
Human engineering creates gravity. Agentic engineering makes it compound.
Engineer your gravity.
A local-first, human-and-agentic operating system that turns meaningful encounters into shared intelligence, useful artifacts, trusted relationships, and rooms people want to return to.
The next personal operating system will not merely manage tasks. It will compound the ideas, relationships, rooms and opportunities surrounding a human.
The mechanism
Five forces of human gravity
Gravity = Direction × Signal × Contribution × Convening × Reliability
It is a product, not a sum. A zero in any force collapses the whole. You raise gravity by raising your weakest force — not by maxing your strongest.
Direction
Are you moving somewhere worth joining?
People can join a vector, never a fog.
Signal
Are you capturing what you notice?
Attention that evaporates compounds nothing.
Contribution
Do you give before you ask?
Generosity is the only durable form of reach.
Convening
Do you bring people together?
A host creates a field a mere attendee never will.
Reliability
Do your promises come true?
Trust is the interest rate on every relationship.
The division of responsibility
The agent removes friction. It never fakes the act.
Agents increase
- Memory
- Consistency
- Preparation
- Transformation
- Cycle frequency
Agents never manufacture
- Judgment
- Presence
- Generosity
- Trust
- Relationship intent
- Human identity
The line is enforced in code, not just promised in prose: speculation is refused at capture, publication is gated behind explicit approval, and consent is structural.
How it compounds
Four compounding loops
Signal → Artifact
encounter → capture → extract → build → publish → response
Room → Network
thesis → curate → host → synthesize → continue
Relationship → Contribution
remember → appreciate → introduce → contribute → fulfil → recalibrate
Learning → Evolution
observe → evaluate → refine → strengthen the field
Privacy & non-impersonation
Sovereignty is the default, not a setting.
Private by default
Every captured record is private until you decide otherwise. Publication is a separate, explicit human act.
No impersonation, no rankings
Agents never write or send as you without approval. The person record has no score field — it is structurally impossible to add one.
Yours to keep or leave
Local-first storage, zero cloud account, export and delete first-class. The bytes are yours.
A standalone vertical, built on SIP.
The Gravity Engine composes with — but never requires — the rest of the Starlight stack. Every published artifact carries a “Built on SIP” attestation.
