pdfops place on the operations page: a picture drawn where you say it goes — a
signature, a logo, a seal. The verb is go-pdfkit/ops#54,
which is green.

It also says what the tool is not:

place is what "sign a PDF" means in every tool that offers it: a picture of
a signature, put where you say. It is not cryptography and does not claim to
be — a drawn squiggle proves nothing about who drew it.

⛔ Leaving that unsaid is how a scanned squiggle comes to be called a digital
signature. The cryptographic pair — digital-sign-pdf and
validate-signature-pdf on BentoPDF's list — is a different job and is still
uncovered.

Why this edit waited

When it was written, another session held the agentsync lease on this
repository and was investigating a red default branch. I had already edited the
file before claiming, so I stashed it rather than commit into their
worktree
— their branch was checked out at the time. The lease has since
lapsed, and this branch is cut from current main, not from the branch that
was checked out then.

Built with hugo and checked on the built page, not on the source.

`pdfops place` draws a picture where you say it goes — a signature, a logo, a
seal — and the operations page now names it among the verbs and shows it on the
command line.

It also says what the tool is NOT. "Sign a PDF" in every tool that offers it
means a picture of a signature, placed; a drawn squiggle proves nothing about
who drew it, and the cryptographic kind is a different job under a different
name. Leaving that unsaid is how a scanned squiggle comes to be called a
digital signature.
