  • 2026-07-19 18:46:43 — part of check-in [7c2262c837] on branch iss4 — Add `zit stat`: the store's own byte accounting and artifact roll

    The store could not be interrogated about its contents: no way to ask how many artifacts it holds, which ones, or how many of its bytes are artifact content rather than framing. `zit stat` answers that from the frames themselves, emitting `field value` lines: store-bytes, header-bytes, content-bytes, frame-overhead-bytes, config-bytes, artifacts, full-form, deltas. The byte fields account for the file exactly.

    content-bytes and store-bytes stay separate on purpose. Content is measured by summing each artifact frame's payload length; it is never derived from the `.zit` size, which also carries the store header, a header per frame, and alignment padding. A size-derived figure would look like a result and be a fabrication, so the overhead separating the two is reported alongside and stays checkable.

    `--artifacts` lists the stored hashes one per line in ascending order, so two stores' rolls compare with `comm`; `--type=full|delta` narrows by storage form, read from the index the open already built.

    The frame walk and its accounting live in `storestat`, shared with the storage benchmark, so the two cannot drift. (user: dmestas, size: 4941) [annotate] [blame] [check-ins using]

  • 2026-07-19 20:43:40 — part of check-in [921678c019] on branch trunk — Merge iss4: zit stat, the store's own byte accounting and artifact roll

    The store could not be interrogated from outside a checkout: no way to ask how many artifacts it holds, which ones, or how many of its bytes are content rather than framing. zit stat answers from one pass over the frames -- store-bytes, content-bytes, frame overhead, artifact and delta counts. Content is summed from each frame's payload during the walk, never derived from the .zit file size, which also carries the store header, a per-frame header and padding; a size-derived figure would look like a result and be a fabrication, so the two stay separate fields and the overhead between them stays checkable. --artifacts lists the stored hashes for comparison across stores. The frame walk and its accounting live in storestat, shared with the storage benchmark, so the verb inherits the benchmark's exact-accounting test and the two cannot drift.
