Term	Kind	Topic	What it is
Base Layer Rebase Run Image Swap, Image Rebasing	pattern	Container Image Strategy	Replacing the operating-system layers underneath an already-built container image without re-running the application build, so a base-image fix reaches hundreds of services in minutes rather than waiting on ev…
Developer Environment on Demand Ephemeral Environment, Preview Environment	pattern	Developer Environments	A full running instance of the system created automatically per branch or pull request and destroyed when it merges.
Enabling Team	pattern	Platform Team Topologies	A team whose output is other teams' increased capability, working alongside them temporarily rather than owning a component permanently.
Ephemeral Environment	pattern	Developer Environments	A full environment created on demand for one change and destroyed afterwards, which removes the queue for shared environments and the drift within them.
Graduated Escape Hatch Partial Opt-Out, Layered Override	pattern	Abstraction Level Choice	The ability to override one component of a platform's abstraction without abandoning the rest - which prevents a single unmet requirement from causing total defection.
Guardrail	pattern	Guardrails vs Gates	A control that makes the unsafe action impossible or automatically corrected, rather than reviewing it before it happens.
Long-Running Operation SLO Operation Completion Objective, Terminal-State Objective	pattern	Platform SLOs	A reliability objective shaped for multi-minute platform operations like deploys and provisioning - share of runs reaching a terminal state within a deadline with no manual repair - replacing availability perc…
Namespace Tenancy	pattern	Platform Tenancy	Isolating teams within a shared cluster by namespace plus quota plus network policy, and being explicit about what that does not isolate.
