Glossary

The project's language. Every term translated from engineering into family.

Term	In IT / engineering	In marriage
uptime	Share of time a service is available and healthy.	Share of time partners feel safe in the relationship.
failover	Automatic switch to a backup when the primary fails.	A partner picking up the other's duties when they are out.
zero-trust	No source is trusted by default.	Family decisions are made inside the couple; outside input is filtered.
firewall	Rules that filter inbound/outbound traffic.	Agreements on which outside influence gets through.
DDoS	Many small requests exhausting a system.	A stream of unsolicited advice and pressure wearing a couple down.
root	Full unrestricted access.	Excessive power over family decisions held by someone not ready for it.
IAM	Management of roles and access rights.	Who is responsible for what and which decisions belong to whom.

post-mortem	Blameless incident review for lessons.	Reviewing a fight for a lesson, not for blame.
SLA	An agreed service level between parties.	Explicit mutual expectations, spoken rather than assumed.
tech debt	Accumulated shortcuts costly to fix later.	Emotional debt: unspoken grievances that pile up and grow costly.

incident	An event disrupting normal operation.	A fight or crisis knocking the couple out of its working mode.

monitoring	Watching system state for early signals.	Regular check-ins before things go wrong.
redundancy	Duplicated resources for resilience.	A reserve of support and closeness that holds through hard times.
graceful degradation	Smoothly shedding functions instead of full failure.	Losing some functions in a hard period without collapsing entirely.
