Primes¶
- Bulkhead Pattern
- The archetype is the ship hull divided by transverse walls — flood one compartment and the others stay dry, so the vessel lists but does not sink.
This sourceNames and develops the Bulkhead stability pattern — partitioning a shared resource (thread pools, connection pools) per dependency so one failure cannot drain the whole — drawing the explicit analogy to a ship's watertight compartments.

- Center Of Gravity
- Software systems and game strategy: the database, auth service, or build system whose outage halts the product (named "single point of failure" from the defender's side); the playmaking node whose neutralisation changes a contest more than matching any other element.
This sourceTreats single points of failure in production systems and the bulkhead/compartmentalization pattern — isolating a critical service (database, auth, build) whose outage halts the whole product — the defender-side view of the center-of-gravity object.

- Circuit Breaker
- It is one of the most widely implemented resilience patterns in microservice architecture.
This sourcePragmatic Bookshelf. Popularized the software circuit-breaker stability pattern (closed/open/half-open) that fails fast on a degraded dependency, explicitly naming the borrowing from the electrical breaker.

- Latent Realizable Capacity
- and a software circuit-breaker pattern in a microservice mesh, where a service's disposition to fail-fast above an error-rate threshold is configured, triggered, manifested, and reset on exactly the same five handles.
This sourceIntroduces the software Circuit Breaker stability pattern — a service's disposition to fail-fast above an error-rate threshold, triggered, manifested, and reset on the same handles as a physical breaker.

- Propagation
- Software engineering & systems: Error propagation through call stacks and exception chains, signal-handler propagation, dataflow and dependency propagation in computation graphs, cache coherency propagation, distributed-system eventual consistency windows, API call ripple effects through microservices, as Nygard (2007) catalogs through stability patterns and circuit-breaker designs in production systems.

The publisher's description of Release It! confirms the book addresses stability patterns and microservices in production systems, but it states nothing about circuit-breaker states or any catalog of propagation types.
“New coverage includes DevOps, microservices, and cloud-native architecture. Stability antipatterns have grown to include systemic problems in large-scale systems.”

- Unverified Precondition
- The type-level existence-encoding pattern transferred from single-process software into distributed-systems libraries, where reachability checks and circuit breakers treat "is the downstream available?" as a routine question.
This sourcePresents stability patterns — circuit breakers, timeouts, bulkheads — that treat 'is the downstream available?' as a routine existence question to verify at the action site.

Mechanisms¶
- Cascading Failure Containment
- Its strength is speed against a front too fast for people: because containment is wired to leading signals and can act automatically, it can decouple a spreading fault in the seconds before it saturates a system, and it degrades gracefully rather than failing all at once.
This sourceDescribes an automatic circuit breaker that opens after a failure threshold, stops calls to an unhealthy subsystem, and prevents its failure from destroying the larger system.

- Coupling Reduction
- The API is called just as often; what changed is that its trouble no longer transfers directly into the store's critical path.
This sourceDefines bulkheads as partitioning a system so failure in one part does not destroy everything.

- Fallback Trigger Rule
- It is the software circuit breaker pattern applied to modeling: trip to a safe fallback the moment the primary path stops being trustworthy, instead of hammering a broken one.
This sourceDefines a circuit breaker that opens after failures and prevents repeated calls from continuing to hammer a failing dependency.

- Fault Isolation
- It is the direct answer to brittle coupling, and the pattern of tripping-then-cautiously-readmitting is a mature, named discipline in reliability engineering.
This sourceA circuit breaker trips around a failing dependency and cautiously tests recovery before fully readmitting traffic.

- Half-Open Circuit Probe
- Its strength is that it prevents recovery from becoming a second outage and contains the blast radius of a flapping dependency: the probe, not the crowd, absorbs the risk of testing too soon.
This sourceDefines half-open recovery as allowing one trial call after a timeout; success restores normal traffic and failure immediately reopens the breaker, limiting risky recovery exposure.

- Service Topology Rewiring
- In that mode the rewiring sheds nonessential calls (recommendations, personalization) so their load stops competing with checkout; it trips a circuit breaker on a slow downstream inventory service so its timeouts stop cascading back into checkout; and it reroutes read traffic to a healthy replica region.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Read against the text for 1 of 17 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
