   - [ ] LLoL to review scope statement below --- confirmed 2026m08d03 as
         "site content under StayVS versioning only". Widening it later
         (third-party contributions, reuse by other projects) is a real
         decision, not a detail.
   - [ ] The formal specification does not exist yet. NO operative license
         text may be added to this page until LLoL drafts it. Writing
         plausible-sounding legal language here would be invented authority.

**************************
The Cyrus License: CyLi
**************************

.. warning::

   **This license does not exist yet.** This page states the *principle* CyLi
   is meant to protect and the questions still open. It deliberately contains
   **no license terms** --- the drafting work is genuinely not done, and text
   that merely sounded like a license would claim an authority nobody has
   granted.

   Nothing on this page may be relied on as a license. The license currently
   governing content on this site is the :doc:`Jonah License </license/joli/index>`.


The core principle
====================

**What has been published cannot be revoked, but newer versions can be
published.**

That single sentence is the whole idea. Everything else is machinery for
making it institutionally reliable.


Why this needs a license at all
=================================

:doc:`StayVS </stayvs/index>` already does this *technically*: every published
version (OOv1, PPv2, and so on) is a permanent record, superseded by later
versions rather than overwritten by them.

But a technical convention is only as durable as the person maintaining it.
An institution deciding whether to build on this material has to ask a harder
question: *what stops the author from quietly rewriting version 1 next year?*
Today the honest answer is "goodwill and a git history." That is not enough to
plan around.

CyLi is intended to close that gap --- to make the StayVS guarantee something
a third party can rely on rather than something they have to trust.


What CyLi is intended to guarantee
====================================

For material published on this site under StayVS versioning:

1. Published contributions remain **accessible and attributable**.
2. **No one --- including the original author ---** can retroactively alter
   what was published under a given version number.
3. Improvements are always possible **through new versions**, with the
   versioning history itself being a public record.

Point 2 is the one that costs something. It binds the author, not just
everyone else. A license that only constrains readers would not solve the
problem CyLi exists to solve.


Scope
=======

**Site content under StayVS versioning only.** (Confirmed by LLoL 2026m08d03.)

CyLi is aimed at material published on Balospe.com that carries a StayVS
version marker. It is *not* currently scoped to:

- third-party or institutional contributions (those are covered by the
  :doc:`Jonah License </license/joli/index>`, as is all FeedbackFlow input);
- reuse as a general-purpose license by other projects.

Both of those are plausible later extensions. Neither is claimed now. Keeping
the first version narrow is deliberate: a narrow license that actually works is
worth more than a broad one that has never been tested against a real dispute.


How CyLi relates to the Jonah License
=======================================

They are **different layers, not competitors**, and they answer different
questions:

.. list-table::
   :header-rows: 1
   :widths: 22 39 39

   * -
     - :doc:`JoLi </license/joli/index>`
     - CyLi *(planned)*
   * - Question it answers
     - May I use and share this?
     - Can I trust that this version will still say the same thing later?
   * - Direction it binds
     - Frees the reader
     - Binds the author
   * - Status
     - In force (JoLi MMv1_2024m10d18)
     - Not drafted
   * - Applies to
     - All site content and all FeedbackFlow submissions
     - Site content carrying a StayVS version marker

JoLi removes barriers to sharing. CyLi is meant to remove doubt about
stability. A reader can need both answers at once, which is why CyLi is
planned as a complement rather than a successor.


Why "Cyrus"?
==============

The name honors Cyrus the Great, who issued the first known declaration of
human rights and enabled the return of exiled peoples to rebuild their
heritage. CyLi aims to similarly protect the integrity of intellectual
contributions while enabling continuous renewal.

.. note::

   Until 2026m08d03 this license was written as the "Cycrus License" across
   this site --- a typo, corrected everywhere on that date. The abbreviation
   ``CyLi`` was always correct and is unchanged.


Open questions
================

Recorded so the gaps are visible rather than glossed over. These are genuine
uncertainties, not rhetorical ones:

1. **What enforces it?** A license is a legal instrument, but the guarantee
   CyLi wants is closer to an archival commitment. Is the right mechanism a
   license, a public commitment, a third-party archive deposit, or some
   combination?
2. **What happens on error?** If a published version contains a factual error
   or a harmful mistake, "cannot be revoked" collides with "should be
   corrected." StayVS answers this with supersession plus a visible
   correction notice. Does CyLi need to say more?
3. **What happens if the site disappears?** An immutability promise that
   depends on one domain staying paid for is weak. Does CyLi require a mirror
   or deposit obligation?
4. **Does it bind successors?** If the material changes hands, does the
   guarantee travel with it?
5. **How does it interact with CC0?** JoLi is CC0-based, and CC0 waives
   essentially everything. Can a CC0-licensed work carry an additional
   author-binding stability commitment without contradiction?

If you have experience with any of these --- especially question 5 --- the
FeedbackFlow link at the bottom of this page is the fastest way to say so.


Status
========

**Informal draft (CyLi MMv0r1_2026m03d31).** The formal specification will be
developed as part of the broader :doc:`StayVS </stayvs/index>` and POST System
infrastructure. This page is offered not to be believed, but to be checked.
