# Diagnostics & behavior checks

When a program behaves differently from expectations, start with the smallest reproducible example. We review the file, environment, inputs and available evidence to define the investigation.

SCOPE

## Agree the outcome before work starts.

Compilation, historical testing and continuous demo operation answer different questions. Decide which observations are needed for your project rather than treating one screenshot as full verification.

A repainting check needs observations recorded as new bars arrive, not just an attractive historical chart. Keep times and conditions aligned when comparing versions.

YOUR PROJECT

## A clear handoff on both sides.

### What to prepare

- Journal / Experts logs with account secrets removed

- The symbol, timeframe, dates and preset used

- A description of expected versus observed behavior

### What to agree in the quote

- Findings tied to the supplied evidence

- Agreed fixes or a clearly scoped next-step proposal

- Steps to repeat the verification

PROCESS

## Assess. Agree. Verify. Deliver.

- 01 Describe & send Identify the platform and goal; share files privately.

- 02 Agree the scope Confirm feasibility, output, price and delivery window.

- 03 Review the build Compare against the original under agreed conditions.

- 04 Approve & receive Settle the agreed balance and receive the final files.

Repairs, migration and development are quoted for the agreed scope.
