Fast memory · Working graph
The sea
Agents reason in a live working graph of drafts, hypotheses and partial plans. It moves fast, and it is allowed to be wrong.
Pharos Fabric
A fixed light
for moving systems.
Pharos Fabric is a semantic operating system for governed AI agents. Every actor has an identity, every fact has a source, and every change is entered on the chart.

I — Two kinds of water
Agents work in moving water. Truth has to be charted.
Promotion
The survey
A sounding becomes a charted fact only when it is validated, signed and recorded with its evidence.
Slow memory · Ledger
The chart
What survives review is promoted to an immutable, versioned ledger. Each fact is validated against its shape and attributed to the principal who asserted it.
II — Four bearings
What every agent should be able to answer.
Who am I acting as? What may I do? Where did this come from? Who set the rules? Pharos keeps every answer in one graph.
000° · Identity
Who is acting
Every human, agent, node and service is a cryptographic principal. No shared keys, no anonymous actors.
090° · Capability
What it may do
Permissions are fine-grained verbs on scopes. They are delegated through a trust graph and checked against the graph itself.
180° · Provenance
Where it came from
Every state change is a graph mutation with an author, a time and its evidence. Nothing happens off the record.
270° · Governance
Who set the rules
Policy is data. Shapes, grants and ceremonies are declared in the ledger and enforced by reconcilers, not by convention.
III — Dead reckoning and the fix
Most agents navigate by dead reckoning.
Each step is estimated from the one before, and the error compounds out of sight.
Pharos takes a fix at every step: a position signed against a shared chart. Any decision can be traced back to its evidence, its principal and the moment it was made.
