Deterministic, not random
Every challenge has a known root cause, evidence path, and validation contract.
ABOUT
We think you should meet the incident before it meets you.
Realistic, safe practice builds the judgment required between a broken signal and a verified recovery.Production failures are rarely solved by recalling a syntax trick. Engineers have to interpret incomplete signals, build an evidence trail, repair the smallest responsible boundary, and prove the system recovered.
RepoRehearsal creates that practice loop without asking anyone to learn in production. Every incident runs against a temporary copy with a known failure contract and deterministic validation.
Practice the evidence-driven work between “something is broken” and “we know it is safe.”
Safe by construction
Temporary workspaces, redacted secrets, and allowlisted commands protect original source.
Scored, so you improve
Diagnosis, investigation, repair, verification, and prevention become measurable signals.
EvidencePractice before productionRecovery
From repository to rehearsal
Map the repository
Identify services, routes, migrations, tests, and reliability risks.
Break an isolated copy
Inject one deterministic fault after the clean baseline passes.
Investigate & repair
Use real evidence, make the smallest repair, and verify recovery.
