docs(license): flag the earlier copyright-registration deadline

If the July and August 2026 pushes of the 1.1 code to the public Gitea count
as publication, the three-month window for statutory damages and fees closes
around 29 October to 1 November 2026, not January 2027.

-1. Grant of License
+Zavage Software Freeware License 1.0
 
-This Zavage Software inc. License Agreement (the "Agreement") is a legal agreement between
-you (either an individual or a single entity) and Zavage Software inc. ("Licensor") for the
-use of the software product identified above, which includes computer software and may include
-associated media, printed materials, and "online" or electronic documentation (the "Software").
+Copyright (c) 2024-2026 Mathew Guest <mat@zavage.net> (https://zavage-software.com), who publishes as Zavage Software ("Zavage Software").
 
-By installing, copying, or otherwise using the Software,
-you agree to be bound by the terms of this Agreement. If
-you do not agree to the terms of this Agreement, do not
-install or use the Software.
+Anyone may install and use this extension free of charge, for any purpose. That permission lasts forever for every version this license covers. Without permission, nobody may republish, sell or give away copies of it, changed or not, or reuse its code, text or images elsewhere. You may read its source code, but this isn't an open source license. The full terms follow.
 
+This license covers the browser extension Search with ChatGPT powered by OpenAI! (the "Software"): every version Zavage Software made before this license or publishes with it, under any name and for any browser, together with their source code, icons, images, documentation and store listings. On addons.mozilla.org its add-on ID is {24644f0c-bfcb-4ebd-a16b-bc8a7d154288}. Anything in the Software or its repository history that belongs to someone else, such as another company's logo, isn't covered by this license and stays with its owner. In this license, "you" means the person or organization using the Software.
 
-2. License
+Section 1: What you may do
 
-The Software is licensed, not sold. Subject to the terms of this Agreement,
-Licensor grants you a limited, non-exclusive, non-transferable,
-non-sublicensable license to use the Software solely for your
-internal business purposes.
+You may install and use the Software for any purpose, personal or commercial, on any number of devices, free of charge. You may install it for others too, on devices you manage, such as your family's or your organization's. You may also:
 
-3. Restrictions
+- make the copies you need to install, run, sync and back up the Software, including a copy on an internal server or network share for installing it on devices you manage;
+- read, study and test its source code, including to check its security and privacy, and make the copies you need for that, such as a clone of the official repository; and
+- change your own copy, and use, copy and share the changed version only within your own household or organization.
 
-You may not:
+These permissions are worldwide, permanent and irrevocable: as long as you follow section 2, Zavage Software can't take them back. Section 5 explains what happens if you don't.
 
-    Copy, modify, or create derivative works of the Software.
-    Distribute, sell, sublicense, lease, rent, or otherwise transfer the Software to any third party.
-    Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of the Software,
-    except to the extent expressly permitted by applicable law.
-    Use the Software in any manner that could damage, disable, overburden, or impair the
-    Software or interfere with any other party's use of the Software.
+Section 2: What you may not do
 
-4. Ownership
+Except as this license allows, and unless Zavage Software gives you written permission (an email is enough), you may not:
 
-All right, title, and interest in and to the Software, including all intellectual
-property rights, are and will remain the sole property of Licensor. This Agreement does
-not grant you any rights in or to the Software other than the limited license granted above.
+- publish, distribute, sell, rent or give the Software, or a version made from it (a fork), to anyone else, whether or not you charge for it, including by listing it on an add-on store (such as addons.mozilla.org, the Chrome Web Store or Microsoft Edge Add-ons) or posting it on a public website or in a public code repository. A fork includes a changed copy, a version for another browser, a userscript, and a translation of its code or text, whether made by hand, with AI or with other tools;
+- copy or adapt any part of its code, text, icons or images for anything else, such as another add-on, app, script, website, service or store listing; or
+- remove or change its copyright and license notices.
 
+Sharing a link to the official listing or repository is always fine, and so is naming the Software, quoting short parts of it, or showing its icon and screenshots or videos of it in use, in a review, an article, a tutorial, a class, a security report or a support request. Nothing in this license limits rights the law gives you anyway, such as fair use or fair dealing. Zavage Software keeps every right this license doesn't give you.
 
-5. Termination
+Section 3: Names and logos
 
-This Agreement is effective until terminated. Licensor may terminate this Agreement
-immediately if you breach any term of this Agreement. Upon termination, you must cease
-all use of the Software and destroy all copies of the Software in your possession or control.
+You may use the Zavage Software name and the Software's name and icon to refer to the Software, but not to brand anything else or to suggest that Zavage Software made or endorsed something it didn't. ChatGPT and OpenAI are trademarks of OpenAI. The Software is unofficial and isn't affiliated with or endorsed by OpenAI.
 
+Section 4: ChatGPT is a separate service
 
-6. Disclaimer of Warranties
+The Software opens chatgpt.com in your browser with your text filled in. OpenAI runs ChatGPT under its own terms and privacy policy. Zavage Software doesn't control ChatGPT and isn't responsible for its availability or its answers, or for how OpenAI handles text that reaches ChatGPT through the Software.
 
-The Software is provided "AS IS" and "AS AVAILABLE," without warranty of any kind.
-Licensor disclaims all warranties, whether express, implied, statutory, or
-otherwise, including but not limited to the implied warranties of merchantability,
-fitness for a particular purpose, title, and non-infringement.
+Section 5: If you break section 2
 
+If you break section 2, Zavage Software may tell you so in writing (an email is enough). If, within 30 days of that notice, you stop and undo what you can, such as taking down copies you published, you keep your permissions under this license, though that doesn't excuse the breach. If you don't, or if you break section 2 again after a notice, your permissions under this license end: stop using the Software and delete your copies. Sections 6 to 10 still apply after that.
 
-7. Limitation of Liability
+Section 6: No warranty
 
-To the maximum extent permitted by applicable law, in no event will Licensor be liable
-for any indirect, incidental, special, consequential, or punitive damages, or any loss of
-profits or revenues, whether incurred directly or indirectly, or any loss of data, use,
-goodwill, or other intangible losses, resulting from (a) your use of or inability to use
-the Software; (b) any unauthorized access to or use of the Software; or (c) any other
-matter relating to the Software.
+Because the Software is free, it comes without a warranty:
 
+TO THE EXTENT THE LAW ALLOWS, THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT.
 
-8. Governing Law
+Section 7: Limit of liability
 
-This Agreement will be governed by and construed in accordance with the laws of Denver, CO and the United States,
-without regard to its conflict of law principles.
+TO THE EXTENT THE LAW ALLOWS, FOR ANY CLAIM ARISING FROM THE SOFTWARE OR THIS LICENSE, ZAVAGE SOFTWARE IS NOT LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOST DATA, PROFITS OR GOODWILL, AND ITS TOTAL LIABILITY FOR ALL SUCH CLAIMS WILL NOT EXCEED US$50.
 
+Sections 6 and 7 don't limit liability for death or personal injury caused by negligence, for fraud, for harm caused deliberately, recklessly or through gross negligence, or under product liability laws. They also don't limit any other liability, or take away any consumer right, that the law doesn't allow to be limited or taken away.
 
-9. Entire Agreement
+Section 8: Law
 
-This Agreement constitutes the entire agreement between you and Licensor regarding the use of the
-Software and supersedes all prior and contemporaneous understandings, agreements, representations,
-and warranties, both written and oral.
+Colorado law and United States federal law govern this license. If you use the Software as a consumer, outside your trade, business or profession, you also keep the protections of the law where you live that an agreement can't take away.
 
-10. Contact Information
+Section 9: Earlier and later versions
 
-If you have any questions about this Agreement, please contact Zavage Software Inc. at:
+This license replaces any other terms that came with the versions it covers. A later version may come with different terms, but they can't take back what this license gives you for the versions it covers.

+# Replace the license
+
+Status: implemented on `docs/replace-license`. Researched and reviewed, but not
+legal advice; no lawyer has read it.
+
+## Problem
+
+The old `LICENSE.txt` was a stock business EULA, unchanged since June 2024. It:
+
+- allowed use only "for your internal business purposes", which leaves out
+  people using the extension at home;
+- banned copying and reverse engineering, although the source is public and the
+  listing links to it;
+- named "Zavage Software inc." as licensor, though the code is Mathew's;
+- said users agreed by installing, which binds no one who installs from AMO.
+
+## Goals
+
+1. Anyone may use the extension for free, for any purpose, forever.
+2. Nobody may fork it, republish it, or build or sell anything from it.
+3. Everything else is reserved.
+
+The text must not scare ordinary users away.
+
+## How it was reviewed
+
+Three multi-agent passes on 2026-10-19. Each finding was checked against primary
+sources by a separate skeptic.
+
+1. Seven lenses: US law, international law, platforms, comparable licenses, a
+   would-be cloner, ordinary users and drafting. A completeness critic followed.
+   This pass produced 92 findings.
+2. A four-lens adversarial review of the revision, which produced 29 findings.
+3. A final consistency check and cold read.
+
+## Decisions
+
+- **Custom text.** No standard license fits all three goals:
+  - PolyForm Strict allows noncommercial use only.
+  - PolyForm Internal Use covers business use only.
+  - PolyForm Perimeter, Shield and Noncommercial, Elastic, BSL and FSL all allow
+    redistribution.
+  - CC BY-NC-ND allows sharing unchanged copies.
+- **A permission, not an agreement.** Copyright already forbids forks without
+  anyone agreeing to anything. "By installing you agree" doesn't bind people who
+  install from a store (Specht v. Netscape, 2d Cir. 2002).
+- **Licensor: Mathew Guest, publishing as Zavage Software.** Colorado lists a
+  Zavage Software Inc. LLC, but the code was never assigned to it. Section 10
+  keeps the license in force if the code later passes to a company.
+- **Earlier versions are covered.** On AMO, versions 1.0, 1.2 and 1.3 share one
+  license record (9155), and their signed packages bundle the old EULA. Section 9
+  replaces those terms.
+- **Each version stays free forever.** A later version may carry different
+  terms, but it can't take back what this license gives. The owner chose this
+  over promising that every future version stays free.
+- **Changed copies stay within your household or organization.** There is no
+  route for having Mozilla sign a changed copy. Submitting to AMO makes the
+  submitter warrant worldwide distribution rights (Firefox Add-on Distribution
+  Agreement §5(c)), which this license withholds. Changed copies still run as
+  temporary add-ons, or in Developer Edition, Nightly and ESR.
+- **Reviews are welcome.** Reviews, tutorials, classes and security reports may
+  name the extension, quote short parts, and show its icon and screenshots of it
+  in use.
+- **Liability is capped at US$50**, for claims about the Software only. The cap
+  has explicit exceptions (injury, fraud, deliberate or reckless harm, gross
+  negligence, product liability). A bare "to the extent the law allows" doesn't
+  save a cap in Germany, the UK or the EU.
+- **Clauses left out:**
+  - A courts clause, which binds no forker and is unfair to EU and UK consumers.
+  - A noncompete or a ban on similar extensions. Ideas aren't protected, and
+    such a clause risks copyright misuse.
+  - Clauses on AI training and on outside contributions.
+- **The name is "Freeware", not "Free Use".** "Free Use" has a slang meaning, and
+  "free" alone suggests free software.
+- **The layout is plain text.** AMO shows license text as plain text: every line
+  break shows, and there's no Markdown. So each paragraph sits on one line, and
+  headings read "Section N:".
+
+## Publishing on AMO (untested, 2026-10-19)
+
+1. In the Developer Hub, open the add-on's **Manage Authors & License** page.
+2. Set "What is your license's name?" to `Zavage Software Freeware License 1.0`.
+   The listing's License link and each version's "Source code released under …"
+   line show this name, not the text's first line.
+3. Paste `LICENSE.txt` unchanged, and leave the End-User License Agreement box
+   unticked.
+4. Save. Saving edits the shared record, so 1.0, 1.2 and 1.3 all show the new
+   text, and the next upload inherits it.
+5. Check every version:
+
+   ```sh
+   curl -s https://addons.mozilla.org/api/v5/addons/addon/search-with-chatgpt/versions/ \
+     | jq '.results[] | {version, license: .license.name}'
+   ```
+
+AMO turns the email address into a link to its own home page. It looks odd but
+does no harm.
+
+## Outside the license
+
+- **Register the copyright** with the US Copyright Office (Standard Application,
+  US$65), and exclude AI-generated material that is more than trivial.
+  Registration is needed to sue and to keep a takedown in place after a
+  counter-notice. Statutory damages and fees also depend on registering within
+  three months of first publication.
+  - 1.2 and 1.3 reached AMO on 18 and 19 October 2026, so their window runs to
+    about 18 January 2027.
+  - The 1.1 code was pushed to the public Gitea in July and August 2026. If
+    those pushes count as publication, its window closes around 29 October to
+    1 November 2026. The old license's copy ban suggests they didn't, but that
+    reading is low confidence.
+  - So file by late October 2026 to be safe, and have an IP attorney confirm.
+- **Replace the Chrome repository's `LICENSE.txt`.** It still carries the old
+  EULA and the public@zavage.net contact.
+- **Report clones** through Mozilla's infringement form or
+  dmcanotice@mozilla.com. On AMO, Mozilla's own fork rule is a second route. Use
+  the Chrome Web Store's and Microsoft's DMCA forms for those stores.
+- **Don't mirror the repository publicly on GitHub.** GitHub's terms let any
+  GitHub user fork a public repository there.
