All Rights Reserved.
Author: Sean T. Gilley

LICENSE VERSION AND SCOPE. This is Version 1.0 of the AIShell-Gate
license. This license applies only to the Software package it
accompanies — that is, to all files contained in the release archive
(for example, a .tar.gz, .deb, or .rpm) in which this license file is
distributed. Future versions of the Software may be released under new
or revised license versions; the license version accompanying each
release governs that release.

Personal Use of AIShell-Gate (as defined below) is free of charge
under the terms set out in this file. Commercial Use (as defined
below) requires a valid license purchased from AIShell Labs LLC. The
commercial license terms — including the Standard Edition and
Enterprise Edition licenses, fleet and site licensing, and the
Maintenance and Support Subscription — are set out in the AIShell-Gate
Commercial License Terms, Version 1.0, available at
www.aishellgate.com and upon request from info@aishellgate.com. For
purchased commercial licenses, the agreement issued at purchase
governs; in the event of any conflict between this file and that
document, the issued license document governs.

DEFINITIONS
-----------
"Personal Use" means use of the Software by an individual, for that
individual's own private, non-commercial purposes, where the use is not
undertaken by, for the benefit of, or on behalf of any business,
non-profit organization, or government entity, and is not part of the
operation, management, protection, or administration of any production
computing environment. Personal Use includes evaluation, learning, and
use on an individual's own personal or hobby systems.

"Commercial Use" means any use of the Software that is not Personal Use,
including without limitation any use by, for the benefit of, or on
behalf of a business, non-profit organization, or government entity, and
any use in connection with the operation, management, protection, or
administration of a production computing environment.

"Software" means the AIShell-Gate compiled program files, scripts,
documentation and all other files contained in a release, singly,
or packaged by tar (including .tar.gz and similar compressed
archives), .deb, .rpm etc. as released by AIShell Labs LLC, exclusive
of source code. For the avoidance of doubt, this license covers every
file contained in the release archive it accompanies.

"ReDistribution Package" means the complete, unmodified set of files
comprising a general release of the Standard Edition Software, as
released by AIShell Labs LLC, including this license file.

"Embedded Catalog" means the proprietary database or catalog of
information contained within the Software, including without
limitation its listings of Linux commands and command flags, denial
and approval reasons, risk or policy scores and scoring criteria,
rules, and related metadata, in whole or in part, in any form or
representation, whether accessed within the Software or observed in
its output.

"Licensee" (also referred to in this license as "you" or "your") means
the individual or entity that installs, uses, copies, or redistributes
the Software under this license. Where an individual acts on behalf of
a business, non-profit organization, or government entity, "Licensee"
means that entity, and the individual represents that they have
authority to bind it to these terms.


ACCEPTANCE
----------
  1. ACCEPTANCE BY USE. By installing, copying, accessing, or otherwise
     using the Software, Licensee accepts and agrees to be bound by
     the terms of this license. If Licensee does not agree to these
     terms, Licensee must not install, copy, access, or use the
     Software.

  2. NOTICE. The Software displays a notice at invocation stating the
     copyright, that the Software is provided without warranty, that
     Commercial Use requires a purchased license, and that use of the
     Software constitutes acceptance of this license.


PERSONAL USE GRANT (No Charge)
------------------------------
  1. GRANT. AIShell Labs LLC grants you a license to install and use
     the Standard Edition Software for Personal Use, at no charge.

  2. NO EXPIRATION. This Personal Use grant does not expire and is not
     time-limited. It applies to the specific version of the Software
     obtained under it. It does not include any right to receive
     future versions, updates, upgrades, or new releases at no charge
     or under these terms; future versions may be released under
     different terms. Bug fix patches for your already-obtained
     version — corrections to defects, including security-relevant
     fixes — are made available at no additional cost in a customer
     self-service format at www.aishellgate.com.

  3. CHANGE IN USE. If your use of the Software changes from Personal
     Use to Commercial Use, you must obtain a Commercial Use license
     before continuing to use the Software for that Commercial Use.

  4. SUPPORT. Personal Use installations receive self-service support
     only — the documentation and knowledge base published at
     www.aishellgate.com.


COMMERCIAL USE (License Required)
---------------------------------
  1. LICENSE REQUIRED. Commercial Use of the Software requires a
     license purchased from AIShell Labs LLC. This file grants no
     Commercial Use rights.

  2. COMMERCIAL TERMS. The available commercial licenses, their scope,
     and their terms are set out in the AIShell-Gate Commercial
     License Terms, Version 1.0, available at www.aishellgate.com and
     upon request from info@aishellgate.com. The agreement issued at
     purchase governs each purchased license.

  3. UNLICENSED COMMERCIAL USE. If AIShell Labs LLC identifies
     unlicensed Commercial Use, it will provide written notice, and
     the user has thirty (30) days from that notice to cure by
     obtaining the applicable license or ceasing the Commercial Use.
     Failure to cure is grounds for termination under TERMINATION,
     below, and AIShell Labs LLC may pursue any remedy available at
     law.


REDISTRIBUTION
---------------
This section grants a right to copy and distribute the Software. It
does not grant any right to use the Software: use of a redistributed
copy remains governed by the Personal Use and Commercial Use terms
above.

  1. GRANT. AIShell Labs LLC grants to any person or entity a
     royalty-free, worldwide, non-exclusive license to copy and
     redistribute the ReDistribution Package, by any means and through
     any channel — including without limitation software repositories,
     package archives, mirrors, installation media, and commercial or
     non-commercial hosting services that host the ReDistribution
     Package for download — without payment of any fee or royalty to
     AIShell Labs LLC and without seeking further permission, provided
     that:

       a. the ReDistribution Package is redistributed complete and
          unmodified, as released by AIShell Labs LLC;

       b. this license file is included, unaltered, with every copy;
          and

       c. no copyright, trademark, or attribution notice is removed or
          altered.

  2. NO PARTIAL REDISTRIBUTION. Extracting, repackaging, or
     redistributing any subset of the ReDistribution Package's files
     separately from the complete package is not permitted.

  3. REPACKAGING FOR DISTRIBUTION FORMATS PERMITTED. Wrapping the
     ReDistribution Package in a distribution's native package format
     (for example, a .deb, .rpm, or similar container, including
     associated metadata, checksums, and installation scripts required
     by that format) is not a modification of the Software for purposes
     of this section, provided the Software files themselves are
     included unmodified and this license file is included unaltered.

  4. SCOPE. This section applies only to the generally released
     Standard Edition ReDistribution Package. It does not apply to any
     Enterprise Edition license credential or to source code. This
     section grants a right to distribute the Software as itself; it
     does not extend to embedding it in another product or offering it
     as a hosted service, which are addressed under NO EMBEDDING OR
     HOSTED SERVICES, below.

  5. NO ENDORSEMENT. Redistribution under this section does not imply
     any endorsement, partnership, or relationship between AIShell Labs
     LLC and the redistributing party.


NO EMBEDDING OR HOSTED SERVICES
-------------------------------
REDISTRIBUTION, above, grants a right to copy and hand out the Software
as itself, complete and unmodified. It does not grant a right to build
on the Software, incorporate it into something else, or use it to
provide services to others.

  1. EMBEDDING. You may not incorporate the Software as a component of
     a different product — including a wrapper, plugin, or repackaging
     — where a recipient cannot readily identify that they are getting
     AIShell-Gate itself, under its own name. Redistributing the
     complete, unmodified ReDistribution Package under REDISTRIBUTION,
     above — including through a Linux distribution's package archive,
     a container registry, or a general-purpose file mirror — is not
     embedding, provided the recipient can plainly see they are
     installing AIShell-Gate. Packaging metadata required by a
     distribution format (see REDISTRIBUTION, Section 3) does not
     defeat this.

  2. HOSTED SERVICES. You may not operate the Software on your own or
     third-party infrastructure and offer its policy evaluation or
     execution-gating functionality to others as a hosted, managed, or
     "as a service" product, whether or not you charge for it.

  3. WRAPPER PRODUCTS. You may not distribute a product whose primary
     purpose is to provide access to, front for, or repackage the
     Software's functionality under different branding, regardless of
     what other functionality that product may also offer.

  4. REMEDIES. A violation of this section is a violation of this
     license. AIShell Labs LLC may pursue any remedy available at law,
     including injunctive relief.


RESTRICTIONS
------------
Except as expressly permitted under REDISTRIBUTION, above, you may not
sublicense, resell, or transfer this Software or any purchased license
to any third party without the prior written consent of AIShell Labs
LLC. You may not remove or alter any copyright, license, or attribution
notices contained in or accompanying the Software.

  1. NO REVERSE ENGINEERING OR BINARY INSPECTION. Except to the extent
     such a restriction is prohibited by applicable law, you may not,
     and may not permit or assist any third party to:

       a. modify, adapt, translate, or create derivative works based on
          the Software;

       b. reverse engineer, decompile, disassemble, or otherwise attempt
          to derive, reconstruct, or discover the source code, underlying
          ideas, algorithms, structure, or organization of the Software;
          or

       c. inspect, scan, extract, or read the contents of the Software's
          compiled program files or other binary files by any means or
          tool, including without limitation string extraction utilities
          (such as "strings" or equivalent string reader tools), hex
          editors or hex dump utilities, binary viewers, debuggers,
          memory dump or memory inspection tools, or any other utility
          used to examine, enumerate, or extract embedded text, symbols,
          resources, or data from a binary file.

  2. RELATION TO SOURCE CODE ACCESS. Nothing in this section limits any
     security review and audit rights expressly granted to Enterprise
     licensees under the AIShell-Gate Commercial License Terms and an
     executed Non-Disclosure Agreement, which are governed exclusively
     by those documents.


PROPRIETARY CATALOG AND OUTPUT RESTRICTIONS
-------------------------------------------
  1. OWNERSHIP. The Embedded Catalog is proprietary intellectual
     property of AIShell Labs LLC and constitutes confidential and
     trade secret information of AIShell Labs LLC. No ownership of, or
     license to, the Embedded Catalog is granted under this license
     except the limited right of use described in this section.

  2. OUTPUT FOR CONTEMPORANEOUS USE ONLY. Information from the
     Embedded Catalog issued by the Software in the course of its
     operation — including without limitation denial or approval
     messages, reasons, scores, and command or flag information — is
     provided solely for the Licensee's use of the Software at the
     time and for the purpose for which it was issued.

  3. NO COLLECTION OR COMPILATION. Except as permitted under
     paragraph 4, below, you may not, and may not permit or assist any
     third party to, systematically collect, harvest, scrape, record,
     aggregate, or compile information issued from the Embedded
     Catalog, or otherwise extract the Embedded Catalog by any means,
     for the purpose of building, populating, training, improving, or
     operating any database, catalog, dataset, ruleset, model,
     product, or service outside the Software, whether or not
     commercial and whether or not offered to others.

  4. ORDINARY OPERATION PERMITTED. Normal retention of Software output
     in the Licensee's own system logs, audit records, monitoring
     systems, and support communications, in the ordinary course of
     operating the Licensee's own systems, is permitted, provided such
     records are not used to reconstruct, reverse engineer, or compile
     the Embedded Catalog or any substantial portion of it.

  5. REMEDIES. A violation of this section is a material breach of
     this license. AIShell Labs LLC may pursue any remedy available at
     law or in equity, including injunctive relief.


TERMINATION
-----------
  1. TERMINATION FOR UNCURED DEFICIENCY. If unlicensed Commercial Use
     identified under COMMERCIAL USE, Section 3, above, is not cured
     within the notice period provided there, AIShell Labs LLC may
     terminate this license, and all grants under it, for the Licensee
     by written notice.

  2. TERMINATION FOR MATERIAL BREACH. AIShell Labs LLC may terminate
     this license immediately upon written notice if the Licensee
     breaches the RESTRICTIONS, PROPRIETARY CATALOG AND OUTPUT
     RESTRICTIONS, or NO EMBEDDING OR HOSTED SERVICES sections of this
     license, or otherwise materially breaches this license in a
     manner not capable of cure.

  3. EFFECT OF TERMINATION. Upon termination, all license grants to the
     Licensee under this document end, and the Licensee must cease all
     use of the Software and destroy or permanently remove all copies
     in the Licensee's possession or control.

  4. SURVIVAL. The following sections survive any termination of this
     license: DEFINITIONS, RESTRICTIONS, PROPRIETARY CATALOG AND
     OUTPUT RESTRICTIONS, NO WARRANTY, LIMITATION OF LIABILITY,
     GOVERNING LAW AND VENUE, SEVERABILITY, and ENTIRE AGREEMENT.

  5. NO EFFECT ON OTHER LICENSEES. Termination as to one Licensee does
     not affect the rights of any other person or entity under this
     license, including the redistribution rights granted under
     REDISTRIBUTION, above.


NO WARRANTY
-----------
THIS SOFTWARE IS PROVIDED "AS IS," WITHOUT WARRANTY OF ANY KIND, EXPRESS
OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. AISHELL
LABS LLC DOES NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE,
UNINTERRUPTED, OR FREE OF SECURITY VULNERABILITIES. LICENSEE ASSUMES ALL
RISK ASSOCIATED WITH THE SELECTION AND USE OF THE SOFTWARE.


LIMITATION OF LIABILITY
------------------------
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, AISHELL LABS LLC
SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL,
CONSEQUENTIAL, OR PUNITIVE DAMAGES OR OTHER LIABILITY ARISING FROM OR IN
CONNECTION WITH THE USE OR INABILITY TO USE THIS SOFTWARE, EVEN IF
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE TOTAL CUMULATIVE
LIABILITY OF AISHELL LABS LLC ARISING FROM OR IN CONNECTION WITH THIS
LICENSE OR THE SOFTWARE, REGARDLESS OF THE FORM OF ACTION, SHALL NOT
EXCEED THE GREATER OF (A) THE TOTAL LICENSE AND SUBSCRIPTION FEES
ACTUALLY PAID BY THE LICENSEE TO AISHELL LABS LLC IN THE TWELVE (12)
MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED
U.S. DOLLARS (US $100). THE LIMITATIONS IN THIS SECTION APPLY EVEN IF
ANY REMEDY FAILS OF ITS ESSENTIAL PURPOSE.


GOVERNING LAW AND VENUE
-----------------------
This license is governed by and construed under the laws of the State
of North Carolina, USA, without regard to its conflict of laws
principles. The United Nations Convention on Contracts for the
International Sale of Goods does not apply. Any action or proceeding
arising from or relating to this license or the Software shall be
brought exclusively in the state or federal courts located in Forsyth
County, North Carolina, USA, and each party consents to the personal
jurisdiction and venue of those courts.


SEVERABILITY
------------
If any provision of this license is held to be invalid, illegal, or
unenforceable in any jurisdiction, that provision shall be enforced to
the maximum extent permissible in that jurisdiction so as to give
effect to the intent of the parties, and the remaining provisions of
this license shall continue in full force and effect. Invalidity or
unenforceability of a provision in one jurisdiction does not affect
the validity or enforceability of that provision in any other
jurisdiction.


ENTIRE AGREEMENT
----------------
This license constitutes the entire agreement between the Licensee and
AIShell Labs LLC concerning Personal Use and redistribution of the
Software and supersedes all prior or contemporaneous understandings
regarding its subject matter. Commercial Use is governed by the
AIShell-Gate Commercial License Terms and, for purchased licenses, the
agreement issued at purchase, which governs in the event of any
conflict with this document. No failure or delay by AIShell Labs LLC
in exercising any right under this license operates as a waiver of
that right. Any amendment to this license as applied to a particular
Licensee must be in writing and signed or expressly confirmed by
AIShell Labs LLC.
