• The doctor's flag 13, the spine (OW Spine #614's last half: "the doctor lints the Spine world against it"). On a world where some element carries an x_spine_ key (any other world skips the flag and says so), every element is read by read_spine_element. A listed type whose supertype is off the spine's list or empty is a finding; so is each value the reader drops (its key and value) and a probe that is not in the probe form. Then the audit's definite parts: each row (an Object, Construct, Location or Law of a listed kind, the world's Charter included, since the page exempts none) must be kept by exactly one Title with supertype Seat, through the Seat's field for that type; no seat, or two, is a finding. Every x_spine_depends_on id must be in the world (not checked through a guest key: an id a guest cannot see is not a missing one). Never checked, and named so in the report: a legacy or provenance row's Retirement Event (the page names it by the row's text, which no structure attributes), whether a probe passes, and x_spine_probed. Known-of stubs are not read. Run on the landing's 360 rows as a folder, it names the 21 probes written as prose; every row reads "no seat keeps it" until the seats' Titles land.
• Schema repinned to schema-dist v0.33.0-dist.57 (from dist.56; same canonical 00.33.00, no schema file moved). The .owworld set grows to 93: eight OW-18 cases on NFC, with Unicode 15.1.0's UnicodeData and CompositionExclusions beside CaseFolding. read_world_file agrees with all 93. Its NFC is the interpreter's unicodedata (Python 3.12 ships Unicode 15.0, 3.14 ships 16.0), not a normaliser built from the set's files; the eight cases use characters every one of those versions treats alike.
