DOC. DYP-000INDEPENDENT TECHNOLOGY DIAGNOSTICSREV. 1.3.02026

Find where your system breaks. Before production does.

We determine the operating limits, failure boundaries and technical constraints of complex systems — and prove them with evidence you can reproduce.

01The question

How far can your system go?

Most systems are tested while they work. We examine what happens when conditions stop being ideal.

FIG. 1  Examination output · one agent workflowILLUSTRATIVE · NOT A CLIENT RESULT

The question is not whether your system works. The question is where it stops working.

02The problem

Working is not the same as scalable.

Every system has an operating range. Demos and happy-path tests only ever see the first part of it.

It works.

Normal conditions. Latency is flat, queues stay empty, every request is answered inside its budget.

p99 flat · queue 0–1 · errors 0%

It degrades.

Concurrency, resource pressure and latency start to interact. The tail moves long before the average does.

p99 rising · pools saturating · retries appear

It fails.

The system crosses its operating boundary. Queues grow without bound, retries amplify load, and it does not recover on its own.

p99 unbounded · queue growing · errors climbing

03The examination

We examine the system.

Not your AI, your roadmap or your team. The running system, measured along five dimensions that meet at one boundary.

04Procedure

Five steps. One boundary.

  1. 01SelectOne critical workflow: the one whose failure would cost the most.
  2. 02StressControlled operating conditions, raised one step at a time.
  3. 03ObserveActual behaviour, measured at every step. Nothing assumed.
  4. 04LocateThe boundary identified, together with the mechanism behind it.
  5. 05ProveReproducible evidence: the harness, the conditions, the data.
05The result

You get a boundary.

A documented technical boundary: where the system’s behaviour changes, why, and under what conditions it happens again.

EXECUTIVE FINDING

The workflow holds its 2.0 s p99 budget up to 8 concurrent sessions. Above 8, tool-call retries saturate a shared connection pool and latency grows without bound.

STABLE            DEGRADED  ▲ FAILURE

▲ failure boundary · 8 concurrent sessions
OPERATING CONDITION
Production configuration on staging hardware; one inference endpoint; tool calls through a shared HTTP pool of 8 connections.
OBSERVED BOUNDARY
8 concurrent sessions. At 9, p99 leaves the budget and does not return while load holds.
FAILURE MECHANISM
Retries share the pool with first attempts. At saturation, retries queue behind the requests they retry, and queue depth grows every second.
EVIDENCE
12 load steps × 5 runs. Latency histograms, pool-wait traces, queue depth per second. Appendix A.
REPRODUCTION
Harness, seeds and configuration delivered with the report; one command re-runs every step. Appendix B.
RECOMMENDED ACTION
Give retries their own pool; cap retries at 2 per call with jitter; admit sessions above 8 only when the pool has headroom. Then re-examine.
CONFIDENCE
High. The boundary reproduced in 5 of 5 runs, within one session.

06Engagements

Start with one workflow.

Each engagement answers one question, and leads to the next only if you need it. The first boundary tells you where to look.

  1. 01Failure Boundary72 HOURS Where does one critical workflow stop behaving acceptably? One workflow, one load axis, raised step by step. The boundary and its mechanism. A written result, no meetings. $950Let’s DY it
  2. 02System Boundary Map7 WORKING DAYS How far can the whole system go, and what gives way first? Up to five critical workflows across all five dimensions. The operating envelope, workflow by workflow. One re-examination after your fix. $3,900Request
  3. 03Runtime Diagnostics2–3 WEEKS Why does it break, and does the fix really move the boundary? Scheduling, jitter and determinism. Mechanisms traced to their cause in code. Every fix verified by re-examination. The harness is yours, to run in your CI. from$9,500Request
  4. —Pre-investment examinationPRIVATE Where does the target’s system break, before capital depends on it? Runtime evidence for a deal. Runs alongside DY Research due diligence — one scope, one report — or on its own. Scoped with the dealRequest

The 72-hour fee is credited in full toward the Boundary Map if you continue within 30 days.

Scope and price agreed in writing. Nothing invoiced until the scope is agreed. Your system and results stay private.

Payment by bank transfer or DOGE. How to start and pay.

07For investors

Before you finance scale.

A technical system can look impressive while carrying an undiscovered operating boundary.

DY PROOF provides an independent technical examination before capital, deployment or acquisition depends on the system.

Request an examination

Alongside DY Research due diligence, or on its own. The findings are technical; the investment decision stays yours.

08Principles

Nothing to sell you but the finding.

Independent
No incentive to confirm the conclusion you were hoping for.
Evidence
Every finding is tied to behaviour that was observed and recorded.
Reproducible
Conditions and method are documented, so any result can be re-run.
Confidential
Your system, your data and your results stay private.
Technical
Engineering findings in engineering terms. No management theatre.

STATED PLAINLY

Not a certification
No examination issues or implies qualification under any safety or compliance standard.
Not investment advice
The findings are technical. What to do with them is your decision.
Not a warranty
You receive evidence and reasoning, set out so that they can be checked.
09The ecosystem

One house. Four layers.

From the infrastructure that is built to the diagnostics that prove how systems behave. Each layer works to the same rule: nothing is claimed that cannot be checked.

Independence. AxonOS is open infrastructure, built and funded by the house and bound for independent foundation governance. Belonging to the ecosystem never shapes a finding: if a system under examination competes with AxonOS or builds on it, you are told at scoping, before you commit to anything.
