FuzzUnmarshal, FuzzParseInfo and FuzzCheckURI, in scripts/fuzz.sh: no
panic, no usable address that the rules refuse, ERR_EXTENSION_DATA_INVALID
as the only code of the data of datekeys.capsule, and a host shown that is
in the address as written. 40 s each with -parallel 4, clean.

Fixes of the review of the session of 1 and 2 October that the text of
spec v0.11 already asks for:
- authorkey: String and GoString hide the secret key, which only Secret
returns; ParsePublic refuses a key that is not a point of the curve
(ed25519strict.OnCurve, checked against the square root of testkit).
- capsule: a typed nil in AuthorKey, CMSSigner or Sealer is an error, never
a capsule without the signature or the seal that was asked for. A panic
while evaluating the signature or the seal fails only that part, F1 or
S2, not both. OpenOptions.Accept sees the verdicts before step 18 and can
refuse to publish the files.
- extension.CheckWrite, the rule of encoders of spec 72: the writers of
capsules and .dkk files refuse datekeys.note and datekeys.capsule outside
the arrays where they are registered, or with invalid data.
- CLI: encrypt -sign shows the author key and the code of AUTHOR_MESSAGE
before it signs (rule 20); decrypt -expect-author compares the key of an
F4 and writes nothing unless it matches; decrypt notifies a public note
that it does not show; the lines of the verdicts break at the last space
that fits, each row after the first behind a mark, so that the terminal
never breaks them; L is the payload, not the content.
- locator: a reader rejects an address that breaks 44.1 and keeps the
others; addresses refuse the special-purpose blocks of IANA, IPv6 outside
2000::/3, localhost and local names, characters outside RFC 3986, dot
segments, and a CID that does not decode to version 1 and a multihash;
ParseInfo checks that the locator is an age file with one tlock stanza
for the round of its DateKey; Info.Extension reads what it writes; its
errors carry no normative code.

Fixtures format3_signed_cms (alg 2, two certificates, each sealed, F6) and
format3_sealed (alg 1 and a seal of seal_type 2, F4 and S4), with the
certificates, SIGNERS, the commitments, SEAL_SUBJECT, the token and the
result of each signer in their records. vectors/security_cms.json has 22
frozen areas with their context and verdicts (F1, F2, F5, F6, S1 to S5), and
vectors/locator.json the extension datekeys.capsule with its envelope hidden
in a host, its locator sealed with tlock, the padding at the boundaries and
the rules of the addresses. The README of testdata describes all of it.

CheckURI works on the raw authority, as an HTTP client reads it: no percent
signs, userinfo or backslashes, a host of letters, digits and hyphens or a
public IP literal, a port from 1 to 65535, and Host returns that host. The
integers of the locator stop at 2^53 - 1, and Info.Extension refuses what
ParseInfo would. extension.Standard validates datekeys.capsule through
locator.Standard, and Info.OpenLocator ties the locator to the round of its
own DateKey.
inspect shows the public note as text of the creator, with its prefix and
wrapping and the warning, and says when a note is unusable. encrypt -note
warns that it is public. decrypt -expect-author fails before the release
is requested when the capsule is not format 3. Author key files are read
with the work factor of the spec as their maximum, the passphrase is not
read from a terminal, and two copies of secrets are cleared.

locator has the data of the extension of a .dkk, the locator sealed with
tlock for the round of the DateKey, and the envelope: the .dkc in age, split
into a header that the locator carries and a rest that can hide inside
another file. The plaintext of the locator measures the least multiple of
4096 bytes that holds it. Nothing is downloaded: a reader gives the rest to
OpenEnvelope, which checks its size and digests.
README and CHANGELOG describe what the draft adds.
