Stores counterexamples and gates their reuse in later work.
What it means
in GenOS.
A counterexample falsifies a universal claim under its stated assumptions. The cambium metaphor denotes a growing store of such examples, with conditions retained for valid reuse.
Capture → Replay compression → Recall within scope
For claim ∀x∈D:P(x), a witnessed x*∈D with ¬P(x*) is a counterexample. Reuse requires matching domain and assumptions, not surface similarity.
Explore the mechanism: Counterexample cambium
A qualitative teaching model of this concept. It does not run GenOS or validate its implementation.
The modeled transition may proceed. Change the assumption and move through the stages to inspect the decision path.
How it works
at a glance.
Capture
Record a counterexample with source, version and the claim it challenges.
Replay compression
Run original witness and counterexample cases in a bounded worker. Refuse a compressed procedure that changes a declared decision.
Recall within scope
Revalidate evidence, environment version, conditions and ancestors. Abstain outside the attested domain and propagate supported invalidation to descendants.
What is connected,
and how far.
Replay is limited to structured declarative procedures and at most 10,000 cases in a resource-bounded worker. An arbitrary comparator or success boolean is not proof; timeout refuses compression. Preserving known decisions does not show that all future failures are covered.
Declarative procedures support isolated before/after decision replay, transactional consolidation, contextual Holobiont recall and transitive invalidation. Arbitrary text procedures and general agent memory remain outside this guarantee.
Failure modes have not yet been separately cataloged for this entry; follow the source and evidence links before relying on the mechanism.

An axiomatic basis for computer programming
C. A. R. Hoare · Communications of the ACM 12(10), 576–580
Sets out axiomatic reasoning about program correctness. A checked property is only as relevant as its specification and assumptions.
Open publication ↗Primary research describes the cited mechanism; specific technologies may instead cite their original technical documentation. These sources provide context and do not validate the GenOS implementation.
