Hardening
Hardens LifeOS tests via property-based testing with fast-check. USE WHEN harden, hardening, property test, property based testing, PBT, fast-check, strengthen tests, find bugs example tests miss, universal quantified claim, shrink counterexample, what bugs am I missing, test the tests. NOT FOR new feature tests (bun test directly), grading agent output (Assay), UI verification (Interceptor), finding security vulnerabilities, or building new functionality.

# Hardening Skill
Hardening sharpens tests that already exist without adding new functionality: it turns the universal claim behind a set of example tests into a fast-check property, runs it across generated inputs, and shrinks any failure to the minimal counterexample.
One intent ships. Mutation testing, complexity scoring, duplication scanning, and acceptance-test mutation were once listed here as planned; none is built, and this file no longer advertises them (external review of the v7.40.4 payload, 2026-09-03: a routing table that promises unbuilt intents is the "confidently documented, never existed" class).
## Ideal State
- Every property written states the universal claim behind existing example tests, runs across generated inputs drawn from the function's real input domain, and keeps the examples it sharpens.
- Every failure ends shrunk to a minimal counterexample with its seed, and ends in either a fixed bug or a corrected property.
- What hardening lands is recorded where the system reads it: a `bun-property` row in the ISA's Test Strategy, and a C/R/L Learning entry when a counterexample taught something.
- Functions that cannot carry a universal claim (impure, or no candidate shape) are left to example tests rather than forced into a property.
