+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY

+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY

+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a

+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.

+# Crucible build parity — local == CI, zero-config reproducible
+
+Date: 2026-06-21
+Status: approved (design); implementation pending
+Repos touched: `sow-tools` (Crucible + contract doc + image notes),
+`sow-topdata` (config, flake, wrapper, CI), `sow-assets-manifest` (flake pin),
+and the consumer wrapper/flake pattern shared by every Crucible repo.
+
+Supersedes the resolver-script approach in
+`2026-06-21-topdata-vfx-autogen-channel-design.md` (the channel→tag→`vfxs.yml`
+resolution moves out of a bash wrapper and into Crucible).
+
+## Problem
+
+`crucible topdata build-topdata` run by hand does **not** reproduce the CI
+build. CI runs `scripts/build-topdata.sh`, which resolves the accessory-VFX
+model list with `scripts/resolve-accessory-vfx.sh` and writes
+`.cache/sow-accessory-vfx-manifest.json` **before** Crucible runs; Crucible only
+reads that pre-staged file (`nwn-tool.yaml: manifest_file:`). Run Crucible
+directly and the file never exists, the `optional` consumer skips, and
+`visualeffects.2da` ships **zero accessory rows** — exactly the local build the
+operator observed (637 rows in CI, 0 locally).
+
+Root cause: a **build-output-affecting input is resolved outside Crucible**, in
+a wrapper script. The wrapper, not Crucible, is authoritative for that input.
+
+## Goal
+
+Crucible is the single authority for everything that lands in a build artifact.
+A clone of any consumer repo, on any system, builds the same bytes CI builds —
+with no secret beyond what cloning already required and no hand-written
+configuration.
+
+### Zero-config reproducibility requirements
+
+- **R1 — No extra secrets.** All build-input reads are anonymous: the asset
+  channel pointer (`releases/haks/channels.json`) and `vfxs.yml` are public CDN
+  text. The crucible binary is fetchable anonymously — **verified**: the
+  sow-tools release assets return HTTP 200 without auth, and the bootstrap tries
+  anon before any token, so `CRUCIBLE_TOKEN` in consumer CI is **vestigial and is
+  removed**. Git-LFS asset bytes use the **same** credentials the clone already
+  used — never a separate key.
+- **R2 — No hand-written config.** Every default needed to build is baked into
+  committed `nwn-tool.yaml` and Crucible defaults: CDN base, channel selection,
+  source paths. The user types `crucible topdata build-topdata` and nothing else.
+- **R3 — No host data assumptions, no `NWN_ROOT`.** Builders read every input
+  from the project tree (`nwn-tool.yaml` + committed `data/**/base.json`); no NWN
+  install is required. `NWN_ROOT` is **dead** today — nothing in Crucible reads it
+  (see *NWN_ROOT cleanup* below). The accessory build reads
+  `data/visualeffects/base.json`. (Enforced by the CI parity guard, which runs in
+  a bare checkout with no `NWN_ROOT`.)
+- **R4 — Nix is convenience, not a requirement.** The flake devshell provides
+  `crucible`, `git-lfs`, `jq`, `yq`, etc. on `PATH` for Nix users. Non-Nix users
+  (incl. Windows) get the same Crucible via the `crucible.sh`/`crucible.ps1`
+  bootstrap and a host `git-lfs`; the build path through Crucible is identical.
+- **R5 — Same Crucible, both worlds.** Local dev and CI invoke the same Crucible
+  subcommand against the same committed config. No CI-only pre-steps that change
+  output.
+
+## Parity contract (prevents recurrence)
+
+Added to `sow-tools/docs/consumer-contract.md`. A consumer build wrapper may only:
+
+1. **validate** — a pre-build gate that does not change output;
+2. **publish** — post-build, on a separate artifact;
+3. **resolve the crucible binary** — the bootstrap in `consumer-contract.md`.
+
+A wrapper MUST NOT fetch, resolve, generate, or stage any input Crucible reads
+to produce the artifact. If Crucible needs an input, Crucible acquires it. This
+is the existing "no local-machine assumptions" + "same inputs → identical
+output" rule, made explicit: **the wrapper is not allowed to be authoritative
+for build inputs.**
+
+## Design
+
+### A. Accessory-VFX resolution moves into Crucible
+
+**Config (`sow-topdata/nwn-tool.yaml`).** Drop `manifest_file:`; declare the
+source on the consumer. The 4-group + `mdl` filter is **not** re-declared — it
+is derived from the keys already present under `accessory_visualeffects.groups`:
+
+```yaml
+autogen:
+  consumers:
+    - id: accessory_visualeffects
+      producer: accessory_visualeffects
+      dataset: visualeffects
+      mode: accessory_visualeffects
+      optional: true
+      source:
+        kind: cdn_channel
+        cdn_base_env: BUNNY_CDN_BASE             # default https://depot.westgate.pw
+        channels_path: releases/haks/channels.json
+        manifest_path: releases/haks/{tag}/vfxs.yml
+        release_marker_path: releases/haks/{tag}/haks.json   # the broken-release guard probe
+        channel_env: SOW_TOPDATA_ASSET_CHANNEL   # else derive from git tag
+        offline_override_env: SOW_VFXS_MANIFEST  # dev/air-gapped vfxs.yml path
+      accessory_visualeffects:
+        groups: { chest_accessories: {...}, head_accessories: {...},
+                  head_decorations: {...}, head_features: {...} }
+        # ... rest of the policy block unchanged
+```
+
+New struct field on `AutogenConsumerConfig` (sow-tools
+`internal/project/project.go`): `Source AutogenSourceConfig` with the keys
+above. Validation: when `source.kind == cdn_channel`, `channels_path` and
+`manifest_path` are required and `manifest_path` must contain `{tag}`.
+
+**Resolution (`internal/topdata/autogen.go`,
+`resolveAutogenConsumerManifest`).** A new branch for `source.kind ==
+cdn_channel`, reusing the existing `fetchJSON` HTTP client and the project YAML
+parser:
+
+1. **Offline override.** If `offline_override_env` names a readable file (or a
+   manifest-repo checkout root containing `assets/vfxs.yml`), parse it and skip
+   the network — the dev/air-gapped path.
+2. **Channel.** `channel_env` if set; else from the git tag / `GITHUB_REF_NAME`
+   (`v*-*` → `testing`, `v*` → `current`, otherwise `current`).
+3. **CDN base.** `cdn_base_env` value, else the baked default.
+4. `GET {cdn}/{channels_path}` → JSON → `tag = channels[channel]`.
+5. `GET {cdn}/{manifest_path with {tag}}` → parse YAML `assets[]`.
+6. **Filter** to `restype == mdl` whose `path` is under `vfxs/<g>/` for `<g>` in
+   the `accessory_visualeffects.groups` keys. Derive each entry's `source`
+   (leading `vfxs/` stripped), `group`, `subgroup`, `model_stem`. Sort by
+   `source`. Hand the entries to the existing accessory augmentor unchanged.
+
+**Fail policy (ported verbatim from the resolver — this is the v0.1.4-bug
+guard).** Distinguish *unreachable* (fail open) from *broken* (hard fail):
+
+- channels.json unreachable / not JSON / channel absent → **fail open**: the
+  `optional` consumer contributes no rows and `data/visualeffects/lock.json` IDs
+  are preserved.
+- vfxs.yml network error, or 404 **and** the `release_marker_path` (haks.json)
+  is **absent** for that tag (no published release) → **fail open**.
+- vfxs.yml 404 **and** haks.json **present** → **HARD fail** ("release `<tag>`
+  has haks.json but no vfxs.yml — accessory rows would silently vanish").
+- vfxs.yml present but malformed / no `assets` array → **HARD fail**.
+
+Fail-open writes nothing and lets the optional consumer skip; hard-fail aborts
+the build with the message above.
+
+**Deleted:** `sow-topdata/scripts/resolve-accessory-vfx.sh`,
+`tests/resolve-accessory-vfx-contract.sh`, the `manifest_file:` key, and the
+resolver pre-step at `build-topdata.sh:19`. The four bash contract cases
+(offline override, unreachable fail-open, broken-release hard-fail, no-release
+fail-open) are re-expressed as Go tests in `internal/topdata`.
+
+### B. Git-LFS materialization moves into Crucible
+
+So a bare clone + `crucible` packs real bytes, not pointer stubs (today only
+`build-topdata.sh` pulls LFS, so direct Crucible would ship stubs in CI's
+non-smudging checkout).
+
+Before packing assets into a hak, Crucible: detects git-LFS pointer stubs under
+the asset tree; if any, runs `git lfs install --local` then `git lfs pull` in
+the repo; re-checks and **hard-fails** if stubs remain ("refusing to build from
+pointer stubs"). Uses the clone's own credentials (R1). Requires `git` +
+`git-lfs` on `PATH` — provided by the Nix devshell, a standard host install
+otherwise (a clone without git-lfs already yields stubs, so this is the existing
+host expectation, now enforced loudly by Crucible instead of a wrapper).
+
+A skip control replaces `TOPDATA_SKIP_LFS` for the maintain-tree flow, which
+regenerates the `data/` tree and **discards** the package: a Crucible flag/env
+(e.g. `--skip-lfs` / `CRUCIBLE_SKIP_LFS`) so that one job can opt out. Default
+is fail-closed (pull).
+
+### C. Wrappers thin out
+
+`scripts/build-topdata.sh` (and the shared pattern in every Crucible repo)
+reduces to: validate (gate) → resolve crucible → `crucible <build>`. No input
+resolution, no LFS pull. `sow-module/scripts/package-module.sh` already matches
+this shape (validate → resolve → build); it stays the reference.
+
+### D. CI parity guard (catches the next regression)
+
+A `sow-tools` integration test builds the topdata package via Crucible **alone**
+in a bare checkout (no wrapper, clean `.cache`, no `NWN_ROOT`, anonymous CDN)
+and asserts `visualeffects.2da` contains accessory rows. This is the test that
+would have caught today's bug: it fails if any build-output-affecting step ever
+drifts back out of Crucible into a wrapper, and it enforces R2/R3/R5 mechanically.
+
+The contract rule in `consumer-contract.md` is the written half; this test is
+the enforced half.
+
+### E. NWN_ROOT cleanup (stale, contradicts the goal)
+
+`NWN_ROOT` is unused — no `os.Getenv`, no `--nwn-root` flag, no consumer. The
+only traces are documentation/help-text describing a rule for a thing that does
+not exist: the `## NWN_ROOT rule` section in `consumer-contract.md`, the help
+text in `internal/dispatch/dispatch.go` ("if a builder ever needs an NWN
+root… crucible never guesses from $HOME"), and the `README.md` pointer. That
+old rule — *never guess, require an explicit env* — directly contradicts the
+zero-config goal (R2): it would make a future builder demand a hand-set path.
+
+- **Remove** the `NWN_ROOT` references: the `consumer-contract.md` section, the
+  dispatch help-text lines, the README pointer. Leave the
+  `migration-from-nwn-tool.md` bullet as historical record.
+- **Replace the forward rule.** Should a future builder ever need NWN game data,
+  it **auto-detects** it (the NWN home — containing `modules/`, `hak/`, `tlk/` —
+  and the Steam install path are reliably discoverable), with an optional
+  explicit override for non-standard layouts. Auto-detect first, never a required
+  hand-set env. This keeps "clone → run → Just Work" intact even for a builder
+  that one day reads game data. None do today.
+
+### F. Toolchain convergence — one Crucible, three modes
+
+Parity needs everyone to run the *same* Crucible. Today three mechanisms
+diverge: non-Nix uses the `crucible.sh` bootstrap download; sow-assets-manifest's
+flake pins `crucible v0.2.5` via `fetchurl`+hash; sow-topdata's flake ships no
+crucible at all (falls back to the bootstrap, with a needless `CRUCIBLE_TOKEN`).
+The pin is scattered (a hardcoded flake version, none in another flake, an image
+sha in `prod.yml`, a HEAD-floating CI binary build).
+
+Converge on **one binary, one pin, three modes — all anonymous, all identical**:
+
+1. **Non-Nix (local + CI fallback).** `crucible.sh` / `crucible.ps1` bootstrap
+   downloads the release binary anonymously. `CRUCIBLE_TOKEN` is dropped from
+   consumer CI (R1).
+2. **Nix (local + CI optimized).** Every consumer flake provides `crucible` in
+   its devshell from a **sow-tools flake input**, pinned by that repo's
+   `flake.lock`. Idiomatic, reproducible, no manual hashes; bump with
+   `nix flake update`. This replaces sow-assets-manifest's manual `fetchurl`
+   pin and **adds crucible to sow-topdata's devshell** (today it has none).
+3. **CI** runs the *same* `crucible <build>` as local, inside the nix devshell
+   (binary-cache fast). No build container, no token, no CI-only pre-steps.
+
+**Pin source of truth = `flake.lock` per repo**, bumped deliberately in a PR. We
+**reject floating "latest"**: it would let local drift from CI between releases
+and break reproducibility. The non-Nix bootstrap, which resolves "latest" by
+default, is the convenience path; reproducible/parity-critical builds pin (nix
+devshell, or `CRUCIBLE_*` pin env for the bootstrap).
+
+### G. The crucible container is deployment-only
+
+`sow-tools` builds and publishes `registry.westgate.pw/deployment/crucible:<sha>`
+on `v*` tags (`nix build .#image` → `skopeo`). It exists for **deployment** —
+`prod.yml` pins it so tools travel with the runtime host (`nwn.enable`), and it
+is a **disabled placeholder** until the NWN stack lands. No build/CI job consumes
+it, and the host-mode runners have no container runtime to run it. It is **not a
+build tool.**
+
+- Keep the image build (cheap, `v*`-gated) for its deployment purpose.
+- **Fix `consumer-contract.md`:** remove the crossed-out "run CI inside the
+  pinned image" guidance and its OPERATOR NOTE; state plainly that builds use the
+  binary (bootstrap or nix devshell) and the image is deployment-only. This kills
+  the "why do we build a container we don't use?" confusion.
+
+### H. Autogen lock identity — model-anchored, immutable
+
+**General lock contract (hard rule, all datasets).** A dataset lock maps a stable
+key to a row id. The build MUST: reuse the existing id for a key that still
+exists; allocate the first free id (lexicographic 0→1→2…) for a new key; and free
+an id only when its key is gone everywhere. An id, once assigned to a live key,
+never changes. (Already implemented for the accessory consumer via
+`historicalLockData` reuse + `nextAvailableAutogenID`; this section makes it the
+written rule and fixes the autogen-specific anchor below.)
+
+**The autogen problem.** Autogen rows describe models that do **not** exist in
+`sow-topdata/data/` — they live in the asset `vfxs.yml` manifest. Today the lock
+key is the *config-derived presentation key*:
+`KeyFormat = {dataset}:{group}{delimiter}{category_segment}{stem}`. Group token,
+category, delimiter, case, and prefix-stripping all come from `nwn-tool.yaml`, so
+a **config-only** change (`key_format`, `delimiter`, `case`, a group rename,
+`category_from`, `strip_model_prefixes`) changes the key → the lock no longer
+matches → a new id is allocated → **every row shifts**. That is a config edit
+silently reshuffling ids for models that never changed.
+
+**Fix — anchor the lock identity on the dataset + model, not the presentation.**
+The lock key for an autogen row becomes `{dataset}:{model_source_path}` — the
+stable `dataset` namespace prefix (kept as the 2da/namespace linker developers use
+instead of raw ids) plus the **model source path** from `vfxs.yml`, e.g.
+`visualeffects:head_accessories/hat/hfx_bandana.mdl` (leading `vfxs/` stripped —
+the path is the value already on `entry.Source`). Dropped from the key are only
+the config-derived parts (group token, `category_segment`, `delimiter`, case,
+prefix-stripping). The row's `key`/`label` *columns* still derive from config via
+`KeyFormat`/`LabelFormat` — only the **lock identity** is decoupled and
+model-anchored. Consequences:
+
+- A config-only change keeps every id (the path is unchanged).
+- A model re-export (same path, new `sha256`) keeps its id — a content change is
+  not an identity change. (Audit trail comes free from `git diff` on the committed
+  `vfxs.yml`, which carries `path` + `sha256`; the lock stays a flat `string→int`
+  map — no schema change, no fork of the shared lock format. A future `id`+`sha`
+  object form is a clean later add if observability ever needs it, without
+  changing id semantics.)
+- A renamed/moved/removed model is a genuinely different (or absent) identity.
+
+**One-time cutover remap.** On the first build under `{dataset}:{path}` keys, for
+each current model compute its *old* config-key (with the current policy) and its
+new `{dataset}:{path}` key; if the new key is absent but the old key carries an id
+in the lock, adopt that id under the new key. So ids carry over with zero shift on
+cutover; the now-unreferenced old keys fall stale and are pruned (below).
+
+**Stale pruning.** A lock key absent from the resolved entry set is dropped and
+its id freed for first-free reuse — but **only on a successful, non-empty
+resolution**. The fail-open paths (section A) contribute no entries and skip the
+augmentor entirely, so an unreachable/missing manifest can never mass-prune the
+lock. This realizes the general "free a fully-stale id" rule without risking the
+lock on a transient source outage.
+
+**Testing.** Go tests in `internal/topdata`: config-only change (rename a group
+token, change `key_format`/`delimiter`/`case`) → ids unchanged; model re-export
+(same path, different sha) → id unchanged; model rename/remove → old id freed and
+reusable; cutover remap → existing ids preserved across the key-scheme switch;
+fail-open → no pruning, lock untouched.
+
+## Determinism vs. channel mutability (decision)
+
+The committed topdata commit pins everything **except** the asset channel
+pointer. `current` resolves through `channels.json`, which is intentionally
+mutable, so "reproducible" here means **same commit + same channel state →
+identical bytes**, not "this commit is frozen forever." This is deliberate: the
+accessory rows must track the asset HAKs shipped beside `sow_top.hak`, which is
+exactly what the channel pointer expresses. A given asset release **tag** is
+immutable; the pointer moving is a real input change, and `lock.json` preserves
+accessory IDs across it (no reshuffle). Builds against an explicit tag
+(`SOW_TOPDATA_ASSET_CHANNEL` set, or a `v*` ref) are fully pinned.
+
+This satisfies R1–R5: no secret, no config, deterministic for a fixed input
+set, on any system.
+
+## Testing
+
+- **Go unit tests (`sow-tools/internal/topdata`)** for the `cdn_channel`
+  resolution: offline-override path; unreachable channels.json → fail open;
+  channel absent → fail open; vfxs.yml 404 + no haks.json → fail open; vfxs.yml
+  404 + haks.json present → hard fail (asserts message); malformed vfxs.yml →
+  hard fail; happy path → correct filtered/sorted entries (mdl-only, 4-groups-
+  only, `vfxs/` stripped, group/subgroup/stem). Mirrors the deleted bash
+  contract cases.
+- **Go config validation test** for the new `source` block.
+- **CI parity guard** (section D) in the topdata build workflow.
+- Existing accessory augmentor / lock-preserve tests unchanged.
+
+## Rollout
+
+1. sow-tools: add `AutogenSourceConfig`, the `cdn_channel` resolution branch,
+   LFS materialization, the model-anchored lock identity + cutover remap + stale
+   pruning (section H), the parity-guard test; update `consumer-contract.md`
+   (add the parity contract, remove the `NWN_ROOT` rule per section E, replace the
+   image guidance with deployment-only per section G).
+2. Release Crucible (assets already anon-downloadable — R1).
+3. Toolchain convergence (section F): expose `crucible` from a sow-tools flake
+   input in each consumer flake — add it to sow-topdata's devshell, switch
+   sow-assets-manifest off its manual `fetchurl` pin; drop `CRUCIBLE_TOKEN` from
+   consumer CI; CI builds inside the nix devshell.
+4. sow-topdata: swap `manifest_file:` → `source:` in `nwn-tool.yaml`; delete the
+   resolver script + bash contract test; thin `build-topdata.sh` (validate →
+   resolve crucible → build); pin Crucible via `flake.lock`.
+5. Verify: bare clone → `crucible topdata build-topdata` → 637 accessory rows,
+   no env, no key; and the same command inside `nix develop`.
+
+## Follow-ups (not this work)
+
+- Parts `2da` / `cachedmodels` reinstatement (separate spec) can reuse the same
+  `cdn_channel` source type.
+- Roll the thinned-wrapper pattern review across `sow-module` / `sow-codebase`.
