  the paths of a head and the result of decoding it: U+00A0, accepted,

- path_fold.json: 22 segments with their NFD and their key of R7,
  among them the entries F of CaseFolding, the dotless i, the Kelvin
  and Angstrom signs, Cherokee, Hangul and the whitelist dropped
  before NFD.
- head_schema.json: 63 heads through layers 2, 3 and 4, in key order,
  with the violation of each ERR_HEAD_INVALID; they add comments with
  tags and with loose variation selectors.
- security.json: 21 areas with their verdicts, X, F0, F1, S0, S1 and

  alg 0, an empty key with the seal intact, and a seal that breaks its

-												v0.16: SpecVersion 0.16, the annex of the draft, and the tests in 76

SpecVersion is 0.16, and so is the spec field of every file of testdata,
the frozen security_cms.json and locator.json included. annex/recovery.md
is §79 of the draft v0.16, with the key of words in 79.7. The draft lists
the two new fixtures in 67, says in 79 what recovery_check.sh opens, and
names in 76 the tests that now exist. The CHANGELOG has its section.

See testdata/README.md.",
 								  "unicode_version": "18.0.0",
-												pathrule: the simple lower case of Unicode 18.0.0

The key of words lowers each code point with the simple mapping of
UnicodeData.txt, field 13, of Unicode 18.0.0 (spec v0.11, 38.1), not
with unicode.ToLower, which carries Unicode 15.0.0: U+A7CB lowers to
U+0264 in Unicode 16.0 and later, and a key made in the page, whose
platform knows it, would not open in the CLI.

The generator writes the table for Go and for datekeys-ts, and the
canonical text gains its lines, so TablesDigest changes; paths.json and
path_fold.json record the new one.
