Stress Hardening
Stress hardening exists to answer a different question from small semantic fixtures.
Stress Hardening
Small fixtures tell you whether the logic is correct on readable examples. Stress hardening tells you whether that same logic stays honest when the input becomes large, corrupted, and operationally messy.
Why It Matters
Without stress work, a library can look correct while still hiding problems such as:
- anomaly-heavy performance cliffs
- pathological allocation behavior
- large-batch failure modes that never appear on tiny fixtures
For causal-order, the point of stress hardening is not abstract number chasing.
It is to pressure-test realistic failure shapes at a size where weak spots become visible.
The Conceptual Rule
The important distinction is:
- benchmark numbers by themselves are not the product story
- semantic honesty under ugly data is the product story
That is why the project treats corrupted-dataset stress work as credibility work, not just speed work.
In practice, that means the stress suite should help answer questions like:
- does weak evidence still remain weak under pressure?
- do anomalies stay visible instead of being flattened away?
- does the package remain usable when corruption is dense?
Why The 150k Band Matters
The 150k stress band is best understood as a hardening envelope, not a bragging number.
It is meant to represent a believable operational slice such as:
- a central server outage lasting several hours
- many nodes continuing locally
- a large delayed backlog arriving for reconciliation later
So the scale matters because it makes the corruption patterns operationally meaningful, not because the project is trying to claim unlimited in-memory scale.
Current Extended Validation
The current package guidance is no longer limited to 100k routine guards and 150k hardening language alone.
Named 250k profiles are already in place for both:
- heavier batch validation
- heavier stream validation
Those 250k runs are best understood as operational extended-validation surfaces.
They are heavier than the default lightweight guard path, but they are real runnable checks rather than only tentative future ideas.
