mtlcl410andClaude Opus 5.5 8e2888aad1 M1: EFOpen review fixes: empty password, own crypt filters, keyless saves and unlock
The empty password opens an EFOpen-only document as no password does,
and the credentials of one opened without the key open no other. An
embedded file may name its EFOpen filter in a /Crypt filter of its own,
with no /EFF; handlers older than crypt filters (V1, V2) don't qualify
(hayro-syntax patch 36 too). Saves without the key refuse what they
would have to encrypt: a removed /Encrypt, or an edited or added
embedded file. The password given after opening unlocks the embedded
files, unless one read as stored has been edited.
