+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 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 Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are 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.
+
+  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.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  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 Affero 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. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  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 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 work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero 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 Affero 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 Affero 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 Affero 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
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+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.
+
+  16. Limitation of Liability.
+
+  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
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+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
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            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.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+ *   the size of the file or of the subdirectory's table (u32 each), the
+ *   attributes (u8, 0x10 for a directory), the name's length (u8) and the
+ *   name. Unused bytes of a table are 0xFF, so a left link of 0xFFFF is
+ *   padding, not an entry.

- * A European disc in two languages (Spanish and Italian) has no maps folder
- * but one for each, maps_es and maps_it: the device's language's is taken,
- * else English's, else the first, and its language written to
- * maps/language.txt, which the game asks the Xbox for (game.language unset,
- * port/linux/src/xbox_xapi.c): the menus in it too.
+ * The image is the player's file and nothing read from it is trusted. Only
+ * the root's table and the maps folder's are read, each whole and at most
+ * 4 MB; the walk of a table visits each offset once, goes at most 64 links
+ * deep and looks at most 4096 entries; and a file is written only under a
+ * plain name that no file before it had (ignoring case).

-form a binary tree (each entry: left and right subtree offsets in 4-byte
-units, the start sector, the size, attributes, the name's length and the
-name). Images made from a whole disc put the game partition further in, at
-one of the offsets below.
+Written from a description of the Xbox's disc file system, XDVDFS
+(xboxdevwiki's XDVDFS page, https://xboxdevwiki.net/XDVDFS), as
+XisoExtractor.java is:
 
-Some parts of this code are copyright in@fishtank.com. This product
-includes software developed by in <in@fishtank.com>.
+- Sectors are 2048 bytes and integers little-endian. Sector numbers count
+  from the start of the game partition: an image of the partition alone has
+  it at 0, an image of a whole disc further in (PARTITION_STARTS, tried in
+  that order).
+- The volume descriptor is the partition's sector 32 (at 0x10000). It holds
+  "MICROSOFT*XBOX*MEDIA" at its start and again at 0x7EC, and the root
+  directory table's start sector (u32 at 0x14) and size in bytes (u32 at
+  0x18).
+- A directory table is a binary tree of entries whose root is the entry at
+  offset 0. An entry is a left and a right subtree link (u16 each, in 4-byte
+  units from the table's start, 0 for none), the start sector and the size
+  of the file or of the subdirectory's table (u32 each), the attributes (u8,
+  0x10 for a directory), the name's length (u8) and the name. Unused bytes
+  are 0xFF, so a left link of 0xFFFF is padding, not an entry.
+- A file is one contiguous run of bytes from the start of its sector.
 
-Copyright (c) 2003 in <in@fishtank.com>
-All rights reserved.
+The image is the player's file and nothing read from it is trusted: only
+the root's table and the maps folder's are read, each whole and at most
+4 MB; a table's walk visits each offset once, goes at most 64 links deep
+and looks at most 4096 entries; and a file is written only under a plain
+name that no file before it had (ignoring case).

+# Streamer mode's words
+
+The words streamer mode hides (Settings > Network Setup > Streamer Mode; the
+`streamer.*` settings in `port/linux/README.md`). The game builds them in
+from `port/linux/game/text_filter_terms.inc`, which
+`tools/text_filter_terms.py` writes from Surge AI's list and these files:
+
+| File | Contents |
+| --- | --- |
+| `review.txt` | The review of every base word of Surge AI's list: kept (its group, severity and where it may be found) or dropped, and the spellings dropped. The words are ROT13'd. |
+| `allow.txt` | Words never hidden, however a hidden word sits inside them (Scunthorpe), in plain text |
+| `english.txt` | The words of the English word list (`port/third_party/english-words`) that the list hides, ROT13'd, which `tools/test_text_filter_terms.py` checks |
+
+`python3 tools/text_filter_terms.py --list` shows the table decoded, and
+`--check "some text"` shows what the game would hide in a text.
+
+## Surge AI's list
+
+The words, their categories and their severities come from Surge AI's
+profanity list, "The Obscenity List": 1,598 English profanities and their
+spellings, each with up to three base words, up to three categories and a
+severity that five raters gave it (Mild, Strong or Severe).
+
+Upstream: https://github.com/surge-ai/profanity (gone since; the Internet
+Archive's copy of its page of 1 March 2025 shows an MIT `LICENSE`, whose text
+it did not keep), copied at https://huggingface.co/datasets/mmathys/profanity
+(MIT), revision `c2a17bf3ec64d9b6418ead1cb5f7ef26dbdffccb`: `profanity_en.csv`,
+SHA-256 ca4ff7d713a8e6f6ec2616f489cd09f6fb96b8b3af404a207783be58a91f3ede.
+
+The CSV is not in the repository: give `tools/text_filter_terms.py --surge`
+its path to write the table again (and `HALO_SURGE_CSV` its path for the
+test that checks it).
+
+The groups are made from its categories (`tools/text_filter_terms.py`'s
+`GROUPS`), each base word in one, then reviewed (`review.txt`):
+
+| Group | Surge AI's categories |
+| --- | --- |
+| SLURS | racial / ethnic slurs, sexual orientation / gender, mental disability, physical disability, political |
+| SWEARING | sexual anatomy / sexual acts, bodily fluids / excrement, religious offense |
+| INSULTS | other / general insult, animal references, physical attributes |

+lines at its end): sexual words (porn, hentai and the like), words for
+sexualised minors, hate phrases and harassment ("kill yourself"), each with a
+severity the default levels hide (slurs from mild, swearing from strong).
+
+The table is made from their list, so it carries their notice:

 votes drop both kinds as unknown, so the network version is unchanged.
 
+The text chat (`network_chat.c`): a client sends its player's line to the
+host (`_distributed_message_chat_up`, reliably), which takes it only from
+the client's own stream and from one of that machine's players, at most 5
+lines at once and one each 1.5 seconds after (more are dropped; a machine
+gone from the game has its count let go, so one new to its slot starts
+afresh), its text cut to 63 characters of printable ASCII but `|` (which
+the game's text drawing takes for the start of a code; it becomes `?`, on
+the host and again on each client). The host alone sends the line on
+(`_distributed_message_chat_down`, reliably, with the sender's absolute
+index and its channel, the line's flags): to every client, a team's line
+only to the machines with a player of the sender's team (to every one in a
+game without teams), and a vehicle's line only to those with a player
+riding in the sender's vehicle (the outermost object each unit is a child
+of, so any map's vehicles), as the host has them; the sender's machine gets
+its own line whatever it is. The host shows it itself if one of its own
+players hears it or said it. A client shows only
+the host's lines, its own too, so every machine shows them in one order,
+and takes them (and the chat settings below) only over the host's
+connection's stream: a datagram from the host's address could be anyone's.
+Each local player's view shows the lines that player hears.
+The host's own `/mute <player> [minutes]` and `/unmute <player>` are
+commands, not lines: it keeps a mute by the player's name (in ASCII,
+matched in either case, as the host keeps names apart) and its minutes by
+its own clock, drops the lines of a muted player's machine
+when they come up, and sends that machine alone a notice of the minutes
+left; it tells every machine of each mute and unmute. A notice is a down
+line with `_chat_line_notice_bit` set, its text alone (no sender). A
+client's `/mute` is never sent, and the host takes the text of a line that
+came up as a line, never a command. The host's scoreboard Mute for everyone
+is the same mute (20 minutes), and the host relays none of a muted player's
+machine's voice either (`network_voice.c`'s `voice_host_relay`, by the
+names of the network game's players, which the lobby has too). A
+machine's own scoreboard mute stays its own: it plays none of that
+machine's voice and shows none of its players' lines, and tells no one.
+The host's chat settings (`network.text_chat`: on, links allowed, or off;
+always off while its game is listed in the server browser,
+`p2p_hosting_listed`) go to every client in
+`_distributed_message_chat_config` (one byte of flags), reliably, as they
+change and every 3 seconds. A client without them (from a host without the
+chat, or before they come) has the chat off, and so does a client in a
+public game it joined from the server browser, whatever its host sends (a
+changed host could turn the chat on): while the tunnel reaches the host of
+the listing it joined (`p2p_join_listing`, `p2p_joined_listed_host`; any
+other invite joined since forgets it), it takes no chat line or notice and
+sends none. A client refuses a line the
+settings refuse before sending it, and the host refuses it again whatever
+the client knew, telling its machine why: a changed build gets no further.
+Links are found in the line's text (`chat_text_has_link`): a scheme, `www.`,
+an address of four numbers, or a name and a common top-level domain, its
+dots also written `(dot)`, `[dot]`, `{dot}`, `(.)`, `[.]` or ` dot `, with
+spaces about them or not, or a dot with spaces both sides; a domain that is
+a word as well (`me`, `to`, `is`) counts only with a path, a port or another
+domain after it (`chat_link_domain`).
+Builds without the chat drop the three kinds as unknown, so the network
+version is unchanged.

+### Text chat
+
+Network games have a text chat, as the PC version had. Press T
+(`controls.chat`) to type a line to all the players, or Y
+(`controls.team_chat`) to type one to your team (in a game without teams,
+to all the players). While you type, Tab changes who the line is to, in
+turn: all the players, your team, or your vehicle (the players riding in
+the vehicle you ride in, whatever the map's vehicles are, Custom Edition
+maps' too; on foot, only you see it). Enter sends the line, Escape cancels
+it. While you type, your player does not move.
+
+With a controller, D-pad Up opens an on-screen keyboard at the bottom right
+(on Android, at the bottom in the middle) for a line to all the players:
+the left stick (or D-pad Left and Right) moves between the keys, A types
+the key, X deletes, Y switches capitals, D-pad Up and Down change who the
+line is to (all the players, your team, your vehicle), Start sends the
+line, and B closes the keyboard (the button that closed it does nothing in
+the game until you let it go). Its last row has Aa (capitals), #+= (the
+symbols), space, DEL and SEND. On a touchscreen (Android, and a browser on
+a phone or tablet), the touch controls' D-pad Up opens it, a tap on a key
+types it, and a tap anywhere else closes it: the touch controls hide while
+it is up. While the keyboard is up the controller and the touch controls
+move nothing in the game. The face buttons are the same places on
+other controllers (on a PlayStation controller: Cross types, Square
+deletes, Triangle switches capitals, Circle closes).
+
+The lines show above the motion sensor, in a column a little over half the
+screen wide: a long line wraps onto the next rows, and the line you type
+shows its end when it is wider. The player's name is in the colour of
+their team (blue in a game without teams), the text in a pale blue, and the
+host's notices in a pale gold; WHITE in CHAT TEXT in Settings > Network
+Setup > Multiplayer HUD (`display.chat_style`) draws them all white, as
+Custom Edition does. A line to the
+team says "(team)" after the name, one to the vehicle "(vehicle)". The
+lines go after ten seconds; while you type, the last six rows show. Where
+the touch controls are (Android, and a browser whose touch controls you
+use), the lines go at the top left, the newest highest. In split screen,
+each player's view shows the lines that player hears, and the first player
+types. No line shows, and none can be typed, in a menu, in a cinematic or
+while the HUD is hidden; opening a menu ends the line being typed. A new
+game starts with no lines. A line has 63 characters at most, letters,
+numbers and punctuation but `|` only (ASCII; `|` becomes `?`). `debug.txt`
+gets every line.
+
+Streamer mode (refer to "Streamer mode") hides offensive words in the
+chat's lines and players' names as it does in all the text the game draws:
+only on your screen, never in what is sent, and never in the line you are
+typing.
+
+The host sends each line on: a player of an older build does not see the
+lines and cannot send them. The host takes 5 lines at once from a machine,
+then one each 1.5 seconds; a machine that joins starts afresh.
+
+TEXT CHAT in Settings > Network Setup > Multiplayer HUD (`display.text_chat`)
+can HIDE the chat entirely, for purists and streamers: no lines show, and

+Setup > Teamplay Options (in co-op, Voice and Voting; `network.text_chat`):
+ON (the default: a line with a link, such as `discord.gg/...`,
+`example.com`, `www.`, an address, or `example [dot] com`, is refused),
+WITH LINKS, or OFF. A domain that is a word as well (`.me`, `.to`, `.is`)
+counts only with a path after it (`youtu.be/...`), so that `go.to` and
+`he.is` are not refused. A game listed in
+the server browser (a public internet game) never has the text chat,
+whatever it says (TEXT CHAT shows OFF there, and cannot be changed, while
+LISTING is PUBLIC); a private game, joined by its invite, and a LAN game have
+it as chosen. A player who joins a game from the server browser has no text
+chat in it even if its host turns it on: their game takes no line from that
+host and sends none. Pressing T where the chat is off says so, and a refused line
+tells its sender why.
+
+On the scoreboard (right-click, then click the player), Mute voice and chat
+mutes a player for you alone: you no longer see their lines or hear their
+voice, and nobody else is told. The host's scoreboard also has Mute for
+everyone: no machine sees the player's lines or hears their voice for 20
+minutes, or until the host picks Unmute for everyone, and all the players
+see "Milenko muted for 20 minutes". The mute holds in the lobby too. A
+machine's voice is one: muting one of two players in split screen mutes
+the other's voice too.
+
+The host can also mute a player from the chat: type `/mute <player>
+<minutes>`, as `/mute Milenko 5` (20 minutes when you give none, 1440 at
+most), which mutes their voice too. The player is found as the console's `kick` finds one: the whole
+name in either case, else the one player whose name begins with what you
+typed. All the players see "Milenko muted for 5 minutes". The muted
+player's lines go to no one, and they see how many minutes are left. The
+mute ends when its minutes are up, or with `/unmute <player>`. A player
+who leaves and joins again under the same name, in either case, is still
+muted. Only the
+host mutes: a player's `/mute` is not sent.

+
+The words come from Surge AI's rated list of English profanities, reviewed
+for the game (`port/assets/text_filter`), in three groups, each with a level
+that hides that severity and worse:
+
+| Group | Setting | Default | What it has |
+| --- | --- | --- | --- |
+| SLURS | `streamer.slurs` | `"mild"` (all) | Slurs about race, ethnicity, nationality, religion, sexuality, gender and disability |
+| SWEARING | `streamer.swearing` | `"strong"` | Swearing and sexual words; the mildest (damn, hell) show at `"strong"` |
+| INSULTS | `streamer.insults` | `"off"` | Name-calling that is not a slur |
+
+A word is found however it is dressed: in capitals or with accents, in
+look-alike letters (Cyrillic, Greek, full-width, small capitals), in leet
+(`0` for o, `@` for a, `ph` for f), with its letters stretched ("fuuuck"),
+with punctuation between them (`f.u.c.k`), spaced out (`f u c k`, `fu ck`),
+and with characters the game does not draw (zero-width spaces, the menus'
+`|` codes) between them. Each word may be found inside a name, at a word's
+start, or only as a whole word, as fits it, and some words are never
+hidden though a hidden one is inside them (Scunthorpe). `python3
+tools/text_filter_terms.py --check "some text"` shows what would be hidden.
+
+What it cannot catch: letters added into a word or its letters scrambled, new

+TEXT_FILTER_MATCH.C
+
+Streamer mode's matcher: which code units of a string spell a hidden word,
+however it is dressed (README.md, "Streamer mode"). A string is read as the
+game draws it (draw_string.c's parsers: a wide string's "|n" breaks a line
+and any other "|" hides the character after it; a narrow string's style
+codes are not drawn), and each character it shows becomes an element:
+
+- a letter, of a-z: the case folded, accents and look-alikes (Cyrillic,
+  Greek, full-width, small capitals: text_filter_fold.inc) made plain;
+- a digit or symbol read as letters (leet: 0 o, 1 i or l, 3 e, @ a, $ s...),
+  or as any letter (* # % ?, the last of which is what the server browser's
+  listings show for a character they cannot), which may also be
+  punctuation;
+- a space or punctuation, which a word may be spelled across;
+- anything else, which no word crosses.
+
+Two elements together may read as one letter (ph f, vv w, \/ v, |< k).
+Then each term (text_filter_terms.inc, made by tools/text_filter_terms.py
+from Surge AI's list; and the player's own) is looked for from each element:
+a run of one letter reads as one ("fuuuck"); punctuation may come between
+letters ("f.u.c.k"); spaces too where the pieces are a letter or two
+("f u c k", "fu ck") or the match is whole words ("f uck"). A term's rule
+says where it may be (inside a word, at a word's start, or as the whole
+word), and the allowed words (Scunthorpe) are never hidden. Nothing here
+knows the game: the harness builds it alone (tools/harness).

 XISO.C
 
-Copies the maps folder out of an Xbox disc image (an "xiso"), for the
-desktop ports' first start without game data (sdl_platform.c).
+The maps folder out of an Xbox disc image, for the desktop games (Linux and
+Windows). When no data root has a maps folder, sdl_platform.c asks the player
+for their disc image of Halo and this copies the image's maps folder next to
+the executable. (The Android app's copy of this is XisoExtractor.java, the
+web page's xiso-worker.js.)
 
-The image's file system is XDVDFS, read as extract-xiso does
-(https://github.com/XboxDev/extract-xiso, extract-xiso.c, whose format
-handling this follows; its license is below and in
-port/third_party/extract-xiso/LICENSE.TXT): 2048-byte sectors; a
-volume descriptor at 0x10000 that starts and ends with
-"MICROSOFT*XBOX*MEDIA" and gives the root directory's sector and size; and
-directories whose entries form a binary tree (each entry: left and right
-subtree offsets in 4-byte units, the start sector, the size, attributes, the
-name's length and the name, 4-byte aligned). Images made from a whole disc
-put the game partition further in, at one of the offsets below.
+Written from a description of the Xbox's disc file system, XDVDFS
+(xboxdevwiki's XDVDFS page, https://xboxdevwiki.net/XDVDFS, and the format
+facts OpenCE's readers rely on). What this file relies on:
 
-The files are written to <destination>/maps.partial first, which becomes
-<destination>/maps once they all are, so an interrupted extraction never
-leaves a maps folder that looks complete.
+- Sectors are 2048 bytes and integers little-endian. Sector numbers count
+  from the start of the game partition: an image of the partition alone has
+  it at 0, an image of a whole disc further in (0x0FD90000, 0x02080000 or
+  0x18300000 for XGD2, XGD3 and XGD1 discs). They are tried in that order.
+- The volume descriptor is the partition's sector 32 (at 0x10000). It holds
+  "MICROSOFT*XBOX*MEDIA" at its start and again at 0x7EC, and the root
+  directory table's start sector (u32 at 0x14) and size in bytes (u32 at
+  0x18).
+- A directory table is a binary tree of entries whose root is the entry at
+  offset 0. An entry is a left and a right subtree link (u16 each, in 4-byte
+  units from the table's start, 0 for none), the start sector and the size
+  of the file or of the subdirectory's table (u32 each), the attributes (u8,
+  0x10 for a directory), the name's length (u8) and the name. Unused bytes of
+  a table are 0xFF, so a left link of 0xFFFF is padding, not an entry.
+- A file is one contiguous run of bytes from the start of its sector.
 
-Some parts of this code are copyright in@fishtank.com. This product
-includes software developed by in <in@fishtank.com>.
+The image is the player's file and nothing read from it is trusted. Only the
+root's table and the maps folder's are read, each whole and at most 4 MB;
+the walk of a table visits each offset once, goes at most 64 links deep and
+looks at most 4096 entries; and a file is written only under a plain name
+that no file before it had (ignoring case).

-is kept but the maps.
+Copies the game data into the site's Origin Private File System, where the
+game reads it (/data/maps: port/web/src/web_main.c): the maps folder of the
+player's Xbox disc image of Halo: Combat Evolved, or the files of a maps
+folder the player chose. It runs in a Worker, which can write with
+synchronous OPFS access handles (Safari has no OPFS writable streams). Only
+the maps and loading.tga are kept, and each map's header is checked as the
+game checks it, so that a disc the game cannot play is refused here.
 
-The image's file system is XDVDFS, read as extract-xiso does
-(port/third_party/extract-xiso): 2048-byte sectors; a volume descriptor at
-0x10000 that starts and ends with "MICROSOFT*XBOX*MEDIA" and gives the root
-directory's sector and size; directories whose entries form a binary tree
-(left and right subtree offsets in 4-byte units, the start sector, the size,
-attributes, the name's length and the name). Images of a whole disc put the
-game partition further in, at one of PARTITION_OFFSETS. The image is the
-player's file, so it is untrusted: every offset and size is checked against
-the image and the directory it is read from, and a directory's walk is
-bounded.
+Written from a description of the Xbox's disc file system, XDVDFS
+(xboxdevwiki's XDVDFS page, https://xboxdevwiki.net/XDVDFS, and the format
+facts OpenCE's readers rely on). What this file relies on:
 
-Each map is checked as the game checks it when it loads it (cache_files.c):
-"head" and "foot" signatures, the Xbox's cache version, and the build of a
-retail disc (01.10.12.2276) or of this decompilation's (01.01.14.2342).
+- Sectors are 2048 bytes and integers little-endian. Sector numbers count
+  from the start of the game partition: an image of the partition alone has
+  it at 0, an image of a whole disc further in (0x0FD90000, 0x02080000 or
+  0x18300000 for XGD2, XGD3 and XGD1 discs). They are tried in that order.
+- The volume descriptor is the partition's sector 32 (at 0x10000). It holds
+  "MICROSOFT*XBOX*MEDIA" at its start and again at 0x7EC, and the root
+  directory table's start sector (u32 at 0x14) and size in bytes (u32 at
+  0x18).
+- A directory table is a binary tree of entries whose root is the entry at
+  offset 0. An entry is a left and a right subtree link (u16 each, in 4-byte
+  units from the table's start, 0 for none), the start sector and the size
+  of the file or of the subdirectory's table (u32 each), the attributes (u8,
+  0x10 for a directory), the name's length (u8) and the name. Unused bytes of
+  a table are 0xFF, so a left link of 0xFFFF is padding, not an entry.
+- A file is one contiguous run of bytes from the start of its sector.
 
-Messages from the page: { type: 'image', file } or { type: 'folder', files }
-(a maps folder's File objects). To the page: { type: 'progress', file, done,
-total }, then { type: 'done', files, bytes } or { type: 'error', message }.
+The image is the player's file (4 to 7 GB) and nothing read from it is
+trusted: it is read a slice at a time, only the root's table and the maps
+folder's (each at most 1 MB), and the walk of a table visits each offset
+once, goes at most 64 links deep and looks at most 4096 entries.
+
+Messages from the page: { type: 'image', file } (the disc image) or
+{ type: 'folder', files } (a chosen folder's File objects). To the page:
+{ type: 'progress', file, done, total }, then { type: 'done', files, bytes }
+or { type: 'error', message }. A new copy first removes the old maps folder
+and writes maps/.complete ({"files":[...],"bytes":n}) last: the page takes
+the data as ready only once that marker is there.
