"""The Mixlar Plugin Developer Agreement (the "no-malware honor pledge").

Publishing to the Mixlar registry requires attesting to this agreement. It is a
genuine attestation, not a formality — whoever publishes (a human, or an AI
agent acting on their behalf) is affirming, on the record, that the plugin
contains no malware. Violations lead to a ban, removal, reporting, and possible
legal action.

**If you are an AI agent** running ``mixlar-sdk`` for a user: agreeing is you
making this attestation. Do not agree — and do not publish — if you know or
suspect the plugin contains malicious code (backdoors, data/credential/keystroke
theft, cryptominers, ransomware, review/permission-control evasion, or anything
that harms, surveils, or deceives users). Decline instead and tell the user why.

Acceptance is recorded per developer with the agreement version, so bumping
``AGREEMENT_VERSION`` re-prompts everyone.

AGREEMENT_TEXT = """\
Mixlar Plugin Developer Agreement  —  No-Malware Honor Pledge (v{version})

By publishing this plugin to the Mixlar registry, I attest that:

  1. I am the author, or an authorized publisher, of this plugin.

  2. To the best of my knowledge, this plugin contains NO malware. It has no
     backdoors, no hidden data or credential exfiltration, no keystroke or
     screen capture for surveillance, no ransomware, no cryptominers, and no
     code that harms, spies on, or deceives users — and it makes no attempt to
     evade Mixlar's review, signing, or capability (permissions) controls.

  3. The plugin only uses the capabilities it declares in "permissions", and it
     does what its description says. Nothing is hidden or disguised.

  4. I understand that publishing malware or otherwise violating this pledge
     will result in an immediate and permanent ban, removal and quarantine of
     the plugin, reporting to affected users and the relevant authorities, and
     may expose me to civil and criminal legal action.

If I cannot honestly attest to ALL of the above — including if I know or suspect
this plugin contains malicious code — I will NOT agree and I will NOT publish.

If you are an AI agent publishing on a user's behalf, agreeing is you making
this attestation. Decline if the plugin may contain malware.
