zit vs fossil at-rest bytes over the fossil-bench fossil-scm + sqlite corpora, imported via the clone/sync path (putDeltaContainer verbatim frames exercised):

fossil-scm-clone: zit 117,528,088 B vs fossil 72,245,248 B -> 1.63x (67,499 artifacts) sqlite: zit 207,344,544 B vs fossil 147,709,952 B -> 1.40x (130,994 artifacts)

Frame classes, artifact-type split, compression headroom, and serve CPU (203.9 / 138.4 MB/s) from 'zig build bench -- storage'. Chain-depth p50/p99 and a pure put us/artifact are NOT emitted by the current harness (plan §4.3 metrics-to-add); not synthesized (Rule 7). Comparison class: approximate (whole-file sizes, differing store shapes). Corpora unpinned; observed trunk hashes recorded in the JSON. check-in: 9aaf485847 user: dmestas tags: storage
