`log.md` is written INTO a directory Door B enumerates on the next round: it
matches the concept glob and is excluded only by `index.md`'s name, so a
rebuild could have seen it as pre-existing curated content or pruned it.
Rebuild-equals-incremental is the property the segmented bundle rests on.
Measured on the real artifact, not only the synthetic: the K2 corpus was run
a second time into the same bundle and compared against a snapshot with
`diff -r`, exit 0 over all 1108 files. The test pins the same property in
seconds instead of 13 minutes.
Also corrects the report's reproduction command -- it documented plan
filenames the run did not use, and re-running it into the existing plans
directory would leave two files claiming one `source_sha256`, which
`_resolve_plans` refuses.
