Personal system / public evidence
Sonde is being built to turn point-in-time public information into an evidence trail first. Deterministic market claims and paper-only execution are planned next, with every action and non-action designed to stay explainable.
Simulated funds, always.
One narrow initial scope.
History is never overwritten.
Risk cannot reach a model.
An instrument, not an oracle.
A sonde enters an environment, samples it, and telemeters readings home. Sonde is starting with that evidence pipe; later milestones plan to carry the same trace through claims, risk, paper execution, and outcomes.
LegibilityDecisions retain direct input references and a rationale.
Non-actionsA decline is evidence too — not an omitted error state.
ProvenanceDocument bytes, facts, snapshots, and decisions have a durable lineage.
The system’s memory is its product.
A source request becomes an append-only attempt and immutable document.
Parsers retain typed facts, their source clocks, and direct document lineage.
Each evidence or policy transition forms a snapshot instead of overwriting history.
A prospective claim freezes typed inputs and rationale at the decision cutoff.
Readiness, planning, and a deterministic gate explain proposals and declines.
The paper venue records intent, fills, reconciliation, and exceptions.
Signal, execution, and realism outcomes remain distinct and write-once.
Separate truths, deliberately.
The prospective market claim: next-session open to horizon close, including untraded signals.
What the paper broker actually filled, held, and reported — never substituted for the signal.
A versioned estimate for paper omissions, kept separate from broker and signal truth.
A later pinned analyst is forward-scored in sealed epochs, not backtested.
The gate is side-effect free and cannot import the analyst runtime, a venue, or network clients.
Alpaca is a future paper venue. Moving to real capital requires a new architectural decision.
Attempts, documents, facts, snapshots, decisions, orders, and outcomes are append-only or immutable.
Public source text is treated as attacker-writable data, never as instruction for the system.
The operations cockpit is authenticated and loopback-only. This public site exposes no live state or controls.
Current work is intentionally small.
EDGAR and delayed SIP evidence, stored and visibly traced.
Deterministic signals and their point-in-time outcomes.
Readiness, risk, paper execution, replay, and scorecards.
A separately measured analyst and evidence-led promotion.
Not a public dashboard. A close-up of the surface this system is being built to make worth watching.
A public record of a private system.
Read the decisions, inspect the architecture, and watch this small system become accountable to its own history.
