# ZIP regression fixtures

Fixtures used by the Rust tests are generated deterministically so their binary
structure is reviewable in the test source. The suite covers stored and raw
DEFLATE entries, mixed archives, UTF-8 names, comments, empty archives, data
descriptors, truncated headers and variable fields, inconsistent sizes and
counts, bad CRC values, unsupported methods, and path traversal attempts.

Controlled faulty implementations are experiment fixtures, not production
variants. Their identities and trigger conditions live beside the simulator's
ground-truth configuration and are never loaded by the statistical analyzer.
The analyzer sees only assignments, execution counts, and observable events.
