# LEG-02 change-pressure reproduction

This synthetic Laravel 13 fixture compares a polymorphic delivery-service
registry with a validated rule table. Both implement one caller-visible
contract and begin with identical standard and express behavior.

Run the current baseline controls with:

```sh
./run.sh
```

The fixture establishes the neutral baseline contract, direct cross-design
parity, stable option ordering, boundary cases, duplicate service-code refusal,
and independently mounted registry and rule-table locker changes with exact
cross-design parity. Capacity-aware same-day variants also retain equal public
results, call guards, and stable provider-failure translation. The table
variant records its transition from scalar definitions to behavior-owning
rules instead of hiding that design change.

The retained runner also applies eighteen isolated defects, emits role-based
source diffs without treating counts as scores, checks source structure and
primary-source observations, and verifies the complete result set.

After committing fixture changes, reproduce the evidence from a clean archive:

```sh
./bin/run-clean-export.sh HEAD
```

The drafting gate remains closed until that archive matches the retained
deterministic results. The clean-export check normalizes only PHPUnit's
elapsed-time field; assertion counts, memory use, matrices, diffs, and verifier
output remain part of the comparison.
