Independent research prototype · v17.18.0

Every prediction.
A record.
A reality check.

A browser workspace that turns changing data into a testable record. Explore probabilities, run a paper portfolio, and see what actually holds up.

Built for the complete loop

From an idea
to an honest result.

There is more to a forecast than a number on a screen. Guardian preserves the inputs, the changes and the outcome so you can inspect the whole story.

01 / CAPTURE

Keep the context.

Record observed live and upcoming markets with prices, score, time and source. Unsupported or stale readings stay clearly marked.

Explore the data flow ↗
02 / EXPERIMENT

Test with paper money.

Run £1 singles and 2–6-leg accumulator drafts against a virtual bankroll. Repeated, unchanged readings never become extra stakes.

Try a simulated scenario ↗
03 / REVIEW

Make results inspectable.

Separate pending exposure from realised results. Preserve wins, losses, voids and skipped entries. Export the entire trial for review.

The engineering underneath

Small decisions.
A traceable system.

An AI-assisted engineering project built around browser capture, deterministic accounting, test coverage and clear uncertainty.

01

Observe

Read supported, visible data from an owned capture session.

02

Freeze

Save the exact market, price and model before the outcome.

03

Reconcile

Apply an exact result once. Leave unknown outcomes pending.

04

Review

Export the record and compare assumptions with later evidence.
