CertGraph landing page headed “Read the constraint. See the architecture.” beside an interactive excerpt asking which architecture fits a global static site with a private S3 origin.
Landing page with the interactive Model excerpt. Local build, captured 12 September 2026.
CertGraph Deconstructor: answer options marked violates or survives, next to a decision graph linking phrases from the scenario to constraints and answer lanes.
Deconstructor after a worked example: phrases from the scenario become constraints that keep or eliminate each answer. Scenario content is synthetic. Captured 11 September 2026.
CertGraph Architecture Lab: build controls and a challenge brief for a global static site with a private S3 origin, beside an architecture map with CloudFront, OAC, and S3 service nodes.
Architecture Lab with a challenge in progress. Scenario content is synthetic. Captured 11 September 2026.
CertGraph Pattern Trainer: a disaster-recovery question with four strategies, the chosen answer marked not quite and warm standby shown as the supported answer.
Pattern Trainer explaining a wrong answer. Synthetic practice content. Captured 11 September 2026.
CertGraph mock exam in progress: question 1 of 10 on secure architectures with four answer options, a question map, and a timer.
SAA-C03 practice form A, first question. Synthetic practice questions, not real exam items. Captured 11 September 2026.
01

Problem

Certification study often rewards answer recall while hiding the architecture constraints that separate plausible options from the right one.

02

Actual state

An accepted browser-only SAA-C03 reasoning trainer with synthetic, source-backed scenarios, pattern practice, and short mock forms. Product acceptance is complete; independent AWS subject-matter review and learner-efficacy validation are not.

03

System architecture

Scenario evidence is deconstructed into constraints, which drive tradeoff comparison and an architecture graph with an explainable reasoning path. Everything runs in the browser, and no protected assessment items are stored or republished.

04

Christian's role

Set the learning thesis, the SAA-C03 scope, the constraint and graph model, the synthetic-content and source-backing standards, and the acceptance criteria; reviewed and tested the agent-assisted implementation and recorded the independent-review gate.

06

Safety, privacy, and authority boundary

  • No actual, recalled, paid, or protected AWS assessment items are republished
  • Practice content is synthetic and partly agent-assisted
  • Product acceptance is not evidence of improved learning outcomes
  • Independent AWS technical review remains incomplete
07

Current limitation

  • Independent AWS subject-matter review has not been completed.
  • Learner-efficacy validation with SAA-C03 learners has not been run.
08

Next milestone

Complete independent technical review and bounded product discovery with SAA-C03 learners before making any efficacy claim.
