chezmoi parses attribute prefixes left-to-right and 'encrypted_' must
precede 'private_'. The 'private_encrypted_' order silently breaks
decryption: chezmoi consumes 'private_', then treats 'encrypted_foo.age'
as a literal filename and copies the ciphertext verbatim instead of
decrypting it.
models.yml was named 'private_encrypted_models.yml.age' since commit
3c3fab7 and was never decrypting — a stale 'encrypted_models.yml.age'
blob was sitting in ~/.omp/agent/ and the plaintext models.yml was an
unmanaged leftover. .env and zai.key used the plain 'encrypted_'
prefix and were decrypting at umask 0644 (world-readable in isolation;
the 700 ~/.omp/agent/ dir was the only thing shielding them).
This commit:
* renames all three to encrypted_private_{zai.key,.env,models.yml}.age
so chezmoi decrypts AND lands them at 0600 natively
* rewrites run_onchange_35 as 'ensure-omp-secret-perms.sh' covering
all three, as belt-and-suspenders for any box where a secret still
sits at 0644 from a prior apply
* removes the stale encrypted_models.yml.age verbatim blob and its
orphan state entry
* corrects the README perms section to document the prefix-order
gotcha (was misleadingly claiming 'private_' alone gave 0600)
Verified end-to-end on this box: chezmoi managed lists all three as
decrypted targets, scoped apply writes them at 600, chmod script is
idempotent. Other boxes need a 'chezmoi apply' to pick up the rename
and the onchange chmod.
