+                    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

+  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

+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

+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),

+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided

+
+                     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.

+- 修**掉电重启后恢复太慢**：原来开机要 **2 分 10 秒**公网才恢复，
+  那段时间浏览器看到的就是 Error 1033。
+  根因是系统里 NetworkManager 和 systemd-networkd 同时在跑，
+  后者等一个不归它管的网络，干等 2 分钟超时失败，
+  把启动流程一起拖住了。改完 **17 秒**就绪，掉电重启后 24 秒公网可用
+
+- 修**看门狗自己制造不稳定**：它每隔 50 秒重启一次隧道，
+  但隧道重建 4 条连接要 30~60 秒 —— 每次还没建齐就被下一次打断，
+  永远停在"只剩 1 条"的状态。现在重启后有宽限期，
+  并且会区分"没建好过"和"建好过又垮"，后者立刻重启
+
+- **官网重新设计**：层次更清楚，白色简洁风格
+
+- **官网新增产品展示**：手表界面预览（颜色和布局与真实手表一致）、
+  电脑端真实截图、两种连接方式对比图
+
+- 清理**僵尸设备记录**：设备列表原来只增不减，
+  实测一天攒了 75 条无效记录，拖慢手表和网页访问。
+  现在超过 6 小时没上报的自动清掉，占用的配对码一起释放
+
+- 修下载文件用 `HEAD` 探测时长度报 0（部分下载器会误判成空文件）
+
+- 支持 `HEAD` 请求（原来一律返回 501）
+
+## 1.7.1
+
+- 修**卸载卡死**：从控制面板卸载时进度条永远走不完。
+  根因是被控端在无控制台的隐藏进程里调 `AllocConsole` 和
+  读控制台输入，会永久阻塞
+- 修**安装回滚**：旧版本程序还在后台跑时，安装器关不掉它，
+  弹「无法关闭所有应用程序」，静默安装会整个回滚 ——
+  用户看到的是"装了没反应"
+- 修卸载残留：开机自启注册表项没删掉、安装目录留个空壳
+- 修手表连上后**一片白屏**：分页初始化函数从没被调用过，
+  标签栏里只剩一个孤立的指示器
+- 修「被控端已关闭新设备配对」把重装手表的人永久挡在外面：
+  配对码本身就是钥匙，拿着正确的码就该放行
+- 手表端应用名改成 ykxmz
+- 修跨网络**延迟高**：隧道退回了 QUIC（`--protocol http2` 参数丢失），
+  可用率只有 48%；恢复 HTTP/2 后可用率 100%
+- 网络调优持久化：TCP 缓冲 4 MB、FastOpen、
+  空闲后不重置拥塞窗口（长轮询场景关键）
+- 手表提示改成自诊断式：连不上时直接打出双方地址，
+  一眼看出是网段不同还是连错了 WiFi
+- **官网重新设计**：导航 / 功能 / 三步上手 / 下载 / 常见问题
+- 官网改成白色简洁风格
+
+## 1.7.0
+
+- 电脑端改成 **Windows 安装包**（Inno Setup），双击安装，不再需要解压 zip
+- 安装向导里填 6 位配对码，装完手表直接连，不用再跑一次设置
+- 安装包支持静默批量部署：`ykxmz-setup-1.7.0.exe /VERYSILENT /CODE=123456`
+- 三份说明文档合并进安装向导，必须接受才能继续
+- 修配置分裂问题：管理员装的配对码，普通用户账号看不到（数据目录改成按安装位置判断）

+# ykxmz 1.8.0 发布说明
+
+**发布日期**：2026-10-07
+**官网**：https://relay.xxmxxs.top
+**产物**：
+- Windows 被控端：`ykxmz-setup-1.8.0.exe`（14.37 MB，安装包）
+- 服务端：`ykxmz-server-1.8.0.zip`（0.21 MB，随身 WiFi / Linux）

+
+## 一、修「跨网络老断」的真因（Error 1033 / 502 / 530）
+
+这一版最主要的东西。现象是：手机/手表打开中转地址，时不时看到
+Cloudflare 的 Error 1033 或者 502、530，过一会又自己好了。
+
+**根因是 4G 链路会静默断开 TCP 连接** —— 不发 FIN 也不发 RST，
+双方都以为连接还活着。Cloudflare 把请求发到这种「僵尸连接」上就报错。
+
+而 Linux 默认要 **2 小时**才发现连接已经死了，中间这段时间
+服务一直处于「看着在线、实际打不开」的状态。
+
+**改了什么**
+- 把 TCP 存活探测改成 30 秒一次、连续 3 次没回应就断开重连
+  → 最多 60 秒发现僵尸连接
+- 隧道连接数从 2 条提到 4 条。实测只剩 1 条连接时，
+  跨机房回源会失败（可用率 0/12），4 条时稳定 12/12
+
+## 二、修「掉电重启后要等两分钟」
+
+原来设备重启后，要 **2 分 10 秒**公网才能访问，那段时间
+浏览器看到的就是 Error 1033。
+
+原因是系统里有两个网络管理服务同时在跑，其中一个在等
+一个不归它管的网络，干等 2 分钟超时失败，把整个启动流程拖住了。
+
+**改完：开机 17 秒就绪，掉电重启后 24 秒公网可用。**
+
+## 三、看门狗重做
+
+看门狗负责在隧道不通时自动重启它。这一版修了它自己的两个问题：
+
+- 之前它每 50 秒重启一次隧道，但隧道重建连接要 30~60 秒，
+  **每次还没建好就被下一次重启打断**，反而永远恢复不了
+- 加了宽限期；又发现宽限期太长会在链路持续不好时干等
+- 最终逻辑：**建好过又断 = 真故障，立刻重启；一直没建好 = 它在努力，继续等**
+
+## 四、官网重新设计
+
+导航结构更清楚，整体白色简洁风格。
+
+新增产品展示区：
+- **手表界面预览**（颜色和布局与真实手表一致）
+- **电脑端真实截图**
+- **两种连接方式对比图**（局域网直连 vs 跨网络中转）
+
+## 五、清理僵尸设备记录
+
+设备列表原来只增不减，实测一天攒了 **75 条**无效记录，
+拖慢手表和网页访问，配对码占用数也虚高。
+
+现在超过 6 小时没上报的设备自动清掉，它占用的配对码一起释放。
+
+## 六、其它
+
+- 修下载文件用 `HEAD` 探测时长度报 0（部分下载器会误判成空文件）
+- 支持 `HEAD` 请求（原来一律返回 501）
+

+## 验收结果
+
+| 项目 | 结果 |
+|---|---|
+| 全量回归 | **33 个阶段全部通过** |
+| 安装包完整周期 | **20/20**（静默安装 7 秒、卸载 0.6 秒、无残留） |
+| 网页响应头 | **12/12** |
+| 公网可用率 | 26/30 = 86%（底层 4G 丢包 30%，这是链路的上限） |
+
+> 说明：可用率受限于现场 4G 网络质量。换有线网络或把中转
+> 放到有公网 IP 的服务器上可以显著改善。

+# 为什么必须用长轮询测：

+#   量到的是冷启动开销，和真实业务（复用连接的长轮询）差很多。
+#   而且那种方式会看到 18 秒的尾巴 —— 长轮询完全没有。
+#
+# 为什么这次结果可信：
+#   上一轮 A/B 里 quic 那组因为**两次探针用了同一个配对码**，
+#   第二次注册被"一个码只能一台设备"规则拒掉，token 拿到空的，
+#   8 次全 401 —— 那一轮数据作废。这次每个探针都用唯一的新码。

+# 为什么值得测 QUIC：
+#   刚才查出来：隧道连接 30 分钟 0 掉线、0 重连，很稳；
+#   但请求级偶发 000（10 分钟 6 次）。
+#   这是 HTTP/2 over TCP 的**队头阻塞** ——

+r'''中转管理页新增两个功能（中转端逻辑）。
+
+== 功能一：允许/禁止新设备接入 ==
+
+一个开关，关掉之后**只有已经登记过的设备能继续上线**，
+没见过的新设备一律拒绝。
+
+用途：不想让陌生人拿配对码乱试、或者临时把中转"关起来"。
+
+实现要点：
+  * 标志位存在 relay_state.json 里，重启不丢
+  * 判断"新设备"以 deviceId 为准（它装机时生成、重装也不变），
+    不是看配对码 —— 老设备换码也必须能进来
+  * 被拒绝时回一个明确的标记 blocked=True，
+    让客户端能区分"被管理员挡了"和"配对码冲突"，
+    不要用中文错误文案去匹配（文案一改就坏）
+
+== 功能二：修改任意设备的配对码 ==
+
+管理页上每台设备一个"改配对码"按钮，填新码就生效。
+
+实现要点：
+  * 新码必须是 6 位数字
+  * 新码不能已经被别的设备占用
+  * 改的时候要同时更新 codes 映射和 device.code，
+    并清掉该设备**旧码**的映射 —— 否则旧码会变成孤儿条目，
+    仪表盘上"配对码占用"会虚高
+  * 改完立刻 _save()，重启后仍然是新码
+  * 该设备当前的手表会话要踢掉（会话是绑在旧码上的），
+    否则手表还拿着旧会话以为连着，实际电脑已经换了码

+
+    ykxmz-watch-1.8.1.apk    201523 字节 / 66.8 秒  =   3 KB/s

+    ykxmz-setup-1.8.1.exe    只下到 237568/15067199 字节就停了
+
+原因：relay 给所有响应都发 `Cache-Control: no-store`，
+**Cloudflare 完全不缓存** —— 每一次下载、每一张图、每个 favicon
+都要穿隧道回 4G 源站。而回源吞吐只有几 KB/s。
+
+改成可缓存后，Cloudflare 会在用户附近的边缘节点直接发，
+速度是"边缘到用户"，跟 4G 那条腿无关。
+
+== 各路径的策略 ==
+
+    /download/*    public, max-age=604800, immutable
+                   文件名带版本号（ykxmz-setup-1.8.1.exe），
+                   同一名字的内容永不改变，所以可以放心长缓存。
+    /shot/*        已经是 public, max-age=86400（保持不变）
+    /favicon.ico   public, max-age=604800（147 KB，之前每次 3.2 秒）
+    /              public, max-age=60
+                   首页会列出当前版本，缓存久了下新版本会看不到按钮。
+                   60 秒足够挡住刷新的重复回源，又不会让版本信息过期太久。
+    /v1/*          no-store（接口，必须实时）
+
+注意：Cloudflare 默认只缓存一部分扩展名，.exe/.zip/.apk 可能不在
+默认列表里。所以改完必须**实测 cf-cache-status 是不是 HIT**，
+不 HIT 就要在 Cloudflare 后台加一条 Cache Rule（我会告诉用户怎么加）。

+
+排查过程（一步步排除，记录下来免得以后重踩）：
+
+  1. 现象：从控制面板卸载，进度条永远走不完。
+  2. 先怀疑 input()：安装器用 runhidden 调 --uninstall，没有 stdin，
+     input() 会一直等。加了 isatty 保护 —— **没解决**。
+  3. 再怀疑 Popen 没重定向 stdio：_schedule_self_delete 起的 cmd
+     继承了父进程句柄，capture_output 会等管道 EOF。加了
+     DEVNULL 重定向 —— **还是卡**。
+  4. 又发现 _kill_running 用 taskkill /IM ykxmz.exe 把正在卸载的
+     自己杀了（--uninstall 就跑在 ykxmz.exe 里），
+     导致后面的"删自启/删数据"没执行。改成 /FI "PID ne self" ——
+     自启能删了，**卸载仍然卡**。
+  5. 最后看进程状态才定位：卡住的 ykxmz.exe 只有 **1 个线程、
+     0.16 秒 CPU、19MB 内存** —— 明显停在启动早期，根本没干活。
+     那就是 cli_uninstall 第一行的 attach_console()：
+     它对 --windowed 程序调 AllocConsole()，再 open("CONIN$")。
+     在没有控制台的隐藏进程里，这一步**永久阻塞**。
+
+修法：加 --quiet。安装包的卸载器用
+      ykxmz.exe --uninstall --keep-dir --quiet
+      --quiet 下完全不碰控制台（不 AllocConsole、不 input），
+      结果写进 uninstall.log 供排查。
+      实测：不带 --quiet 无限卡住；带了 **0.6 秒返回**。
+
+顺带修的两处（也是实测发现的）：
+  * 安装器关不掉以管理员身份运行的旧实例 -> Inno 弹"无法关闭所有
+    应用程序"，静默下被压成"终止"，**整个安装回滚**。
+    改成 PrepareToInstall 里自己 taskkill /F。
+  * 测试脚本把注册表路径写成 HKCU\\...（少了冒号），
+    PowerShell 静默返回空，"开机自启"永远误报失败。
+
+最终实测（test_installer_cycle.py，20 项）：
+    静默安装   退出码 0，7.1 秒
+    配对码     正确写入 C:\\ProgramData\\ykxmz\\data\\settings.json
+    进程/端口  在跑，8765 监听
+    开机自启   已设置
+    静默卸载   1.2 秒

+或者那条连接正在重连）。原来的逻辑是**一失败就 online = false**，
+于是：

+   从控制面板卸载**永远卡住不结束**。安装包的 [UninstallRun]
+   用 runhidden 调用，没有 stdin，input() 就一直等。
+   改成只在 sys.stdin.isatty() 时才等回车。
+
+2. Popen 没重定向子进程 stdio，导致 capture_output 等管道 EOF
+   _schedule_self_delete 起的 cmd 继承了父进程的 stdout/stderr 句柄，
+   任何用 capture_output 调 --uninstall 的地方都会一直等，
+   表现为"程序卡死"（实测 90 秒不返回，改后 0.2 秒）。
+   Popen 加 stdin/stdout/stderr=DEVNULL。
+   顺带把延迟从 timeout 换成 ping —— timeout 在 DETACHED_PROCESS
+   下没有控制台会立刻失败，等于没延迟直接删。
+
+3. _kill_running 用 taskkill /IM ykxmz.exe 把**自己**杀了
+   --uninstall 本身就跑在 ykxmz.exe 里，这条命令一发，
+   后面的"删开机自启""删数据目录"全都没执行。
+   现象：卸载看着完成了，HKCU 的自启注册表项还留着。
+   改成 /FI "PID ne <self>" 排除自己。
+
+4. 安装器关不掉以管理员身份运行的旧实例 -> 整个安装回滚
+   Inno 自带机制只会"请求"对方退出，遇上常驻的服务进程关不掉，
+   弹"无法自动关闭所有应用程序"，静默模式下被压成"终止"，
+   安装直接回滚 —— 用户看到的是"装了没反应/还是旧版本"。
+   改成 PrepareToInstall 里自己 taskkill /F，关掉 Inno 那套。

+另外修了两个卸载残留：
+   * 安装目录留个空壳 -> [UninstallDelete] 加 dirifempty
+   * ProgramData\\ykxmz 没删 -> 加进 [UninstallDelete]

+还有一处 Inno 写法陷阱（踩了三次）：
+   注释里写 [区段名] 或 {常量} 会让编译直接失败，

+        而且如果已经有一个实例在跑，InstanceLock 会直接 return，
+        连日志都不输出。
+
+== 改法 ==
+
+1. SetupWindow 加一个 mode：
+       mode="first"     第一次设置（保持老行为：防火墙+自启+转静默）
+       mode="settings"  已装好，只改配置
+
+2. 窗口加两样东西：
+       * 中转服务器地址（可不填；只在一个 WiFi 里用就不需要）
+       * 允许新设备接入（开关）
+
+3. main() 改成：
+       --setup             -> settings 模式
+       --silent            -> 静默（开机自启/安装包用，行为不变）
+       没参数 + 没设置过    -> first 模式
+       没参数 + 已经设置过  -> **settings 模式**（不再是静默）
+
+4. 已经在跑的时候：不再"直接 exit 什么都不显示"，而是
+   提示一句"被控端正在后台运行"，然后**照样打开设置窗口**。
+   保存后重启后台实例让设置生效。

+
+== 用户报的问题 ==
+
+「安卓端为什么还是默认填的我的中转站，以后改成手动填，
+  安卓端加一个设置，各种设置就在这里面调」
+
+== 根因 ==
+
+代码里的默认值**已经改成空**了：
+
+    private static final String DEFAULT_RELAY_URL = "";
+
+但你手表上看到的还是 `https://relay.xxmxxs.top` —— 因为
+**老版本 1.5.0 把作者的域名硬编码成默认值**（git 历史里查到了）：
+
+    private static final String DEFAULT_RELAY_URL = "https://relay.xxmxxs.top";
+
+第一次运行它就 `setRelayUrl(默认值)` 存进了 SharedPreferences。
+装新 APK **不会清偏好设置**，所以那个值一直留着。
+
+**用户从来没"选"过这个地址** —— 是程序硬塞的。所以正确做法是
+**一次性迁移**：如果存的就是当时内置的那个域名，当成没设过，清掉。
+
+== 做的事 ==
+
+1. 迁移：把老版本硬塞的那个域名从偏好里清掉
+2. 新增「设置」页，把散落的设置收进来：
+      * 中转服务器（手动填 / 清空）
+      * 记住的配对码（看 / 清）
+      * 已配对设备（看数量 / 清空）
+      * 关于（版本号、连接方式说明）
+3. 首页那个「中转设置（跨网络用）」按钮改成「设置」，进设置页
+4. settingsPanel 纳入 showOnly()，避免再出现"面板漏藏"那类问题

-    * HTTP User-Agent "LanRemote/1.4.0"
-      （Cloudflare 的 Browser Integrity Check 认这个，
-        而且 20 多个测试都在断言它 —— 动它要同步改一大片）

-
-所以只改**用户能看到版本号的地方**：
-    1. android/build_apk.ps1   APK 文件名 + manifest 版本
-    2. docs/*.txt              三份文档
-    3. windows/lanremote/__init__.py   __version__

+r'''检查 Inno Setup 的 .iss 里有没有会害编译失败的写法。
+
+踩过的三个坑，都是 Inno 的 [Code] 解析器**连注释内容也处理**：
+
+  1. 注释里写方括号区段名
+         { 规范化，后面 [Run] 阶段用得到 }
+     报 "无效的区段标记"，编译直接失败。踩了两次。
+
+  2. 注释里写花括号常量
+         { 不带 --keep-dir 的话会 rmdir 删 {app} }
+     Inno 会把 {app} 展开，展开后花括号配不上 ->
+     报 "Syntax error"，编译失败。踩了一次。
+
+  3. 注释里写 {param:XXX|}
+     Inno 会展开它，参数没传就展开成空，同样破坏括号配对。
+
+所以规则：**[Code] 段落里，注释内容不能出现 [Section] 或 {常量}。**
+
+⚠ 判断"是不是注释"必须跳过字符串字面量：
+     ExpandConstant('{app}\x')    <- 这里的 { 在字符串里，不是注释
+     { 这是注释 }                  <- 这里的 { 才是注释

+r'''统一清理两个平台发行版里的重复附件。
+
+背景：
+    重发时如果只"复用已有发行版"，附件会一次次堆积。
+    Gitee 尤其绕：`GET /releases/tags/{tag}` 返回的 `assets`
+    **只有 name 和 download_url，没有 id**，所以没法删。
+    但另一个接口有 id：
+        GET    /repos/{o}/{r}/releases/{id}/attach_files  -> 带 id
+        DELETE /repos/{o}/{r}/releases/{id}/attach_files/{attach_id}
+
+    Gitea/EzHub 则直接有 assets[].id。
+
+策略：同名附件只保留最新的一份，其余删掉。
+支持 --dry 先看要删什么。

+  1. 早上打开 relay.xxmxxs.top 看到 Cloudflare Error 1033 —— "这就是你说的优化好了？"
+  2. "中转管理那边 ui 界面大改，现在难看的要死"
+
+============ 一、隧道 1033/502/530 的真因 ============
+
+之前我只测 15~25 次就说"可用率 100%"，太草率 ——
+实际是**间歇性假活**：隧道显示 ha_connections=2 连着，
+公网却 502/530/000。watchdog 日志把过程记了下来。
+
+根因：**4G 链路静默断开 TCP 连接**（不发 FIN/RST，双方都以为还活着）。
+Cloudflare 把请求发到这条僵尸连接上就回错误。
+Linux 默认 tcp_keepalive_time = **7200 秒（2 小时）**才发现，
+中间这段时间服务一直"看着在线、实际打不开"。
+
+修法（都有实测数据支撑）：
+  1. tcp_keepalive 30 秒 + 每 10 秒探测 3 次
+     => 最多约 60 秒发现僵尸连接并重连
+  2. 隧道连接数 2 -> 4
+     （对照实验：http2+2 只有 1 条连上时公网 0/12；
+       http2+4 稳定 12/12。连接数太少会出现"只有 1 条"的危险窗口）
+  3. 协议定为 http2（cloudflared 自检说 TCP 7844 被墙，
+     但实测 http2 反而比 quic 稳）
+
+实测：http2+4 之后公网 40/40 = 100%，最慢 1.3 秒，0 次重连。
+
+============ 二、中转管理后台重做 ============
+
+原来是几百行内联在 relay.py 的 f-string 里（HTML+CSS+JS 全挤一起），
+改一处样式要在一堆转义花括号里翻。拆成独立模块 relay/admin.py。
+
+新版设计（对齐官网那套白色简洁）：
+  * 吸顶顶栏：品牌 + 运行状态 + 版本/内存/请求数
+  * 公网地址给最大权重（这是用户最需要复制的东西）
+  * 四个数字卡（在线/会话数带颜色区分）
+  * 设备表卡片：状态圆点、等宽配对码、行悬停
+  * 工具卡：网络体检 + 下载区并排
+  * 空状态改成图标+引导文案，不再是干巴巴一句
+  * 窄屏时表格自动变卡片
+
+relay.py 从 2089 行缩到 1550 行。
+
+============ 三、顺手修的两个真 bug ============
+
+1. 设备记录只增不减
+   self.devices 从不清理，被控端每次换端口/重装就多一条，
+   实测一天攒了 75 条僵尸记录，/v1/health 从几 KB 涨到 20KB。
+   加 DEVICE_TTL（6 小时）在 snapshot() 里清。
+
+2. 配对码映射也没清
+   RELAY.codes 和 devices 是一对孪生 dict，
+   只清 devices 会留下指向已删设备的孤儿条目 ——
+   管理页显示"配对码占用 131"，实际一台设备都没有。
+   现在一起清。
+
+============ 四、我自己造的两次事故（如实记录） ============
+
+1. 删文件删过头
+   用"从 _admin_page 截到文件末尾"的方式替换方法，
+   但 _admin_page 后面**还有 _esc/_kb/_uptime/class Server/main()**。
+   结果 relay 起不来，systemd 重启 24 次，所有接口 000。
+   教训：**"删到文件末尾"之前必须先确认末尾有什么。**
+
+2. ADMIN_PATH 引用了不存在的常量
+   路由里写的是字面量，我却在新代码里用了 ADMIN_PATH，
+   管理页一访问就 NameError。现在统一定义了常量。
+
+二者都是"改完没立刻验"造成的。现在每次改完都跑一遍

+
+查 watchdog 日志，发现它在**每 50 秒重启一次隧道**：
+    [10:31:57] 只剩 1 条连接 -> 重启隧道
+    [10:32:22] 重启完

+    [10:32:47] 距上次 50 秒 -> 又重启
+    ... 循环不停
+
+根因（我上一版的错）：
+  隧道在**质量差的 4G 上重建 4 条连接要 30~60 秒**。
+  而我上一版把 MIN_RESTART_GAP 设成 45 秒，并且

+  结果每次隧道还没把连接建齐，就被下一次重启打断，

+
+修法：
+  1. 重启后给 GRACE=150 秒宽限期，这期间绝不重启，
+     让 cloudflared 专心把连接建齐
+  2. MIN_RESTART_GAP 从 45 提到 150（和宽限期一致）
+  3. "立刻重启"的判定加一条：距上次重启必须超过宽限期
+
+实测（停掉 watchdog -> 手动重启隧道 -> 观察）：
+    10 秒内建齐 4 条连接，公网立刻 200
+    宽限期生效后公网 20/20 = 100%，延迟 ~690ms
+
+顺带一个教训：之前测出 80%、20% 的 000，

+r'''最小复现：只解压两个 zip，看进程会不会被杀。
+
+线索：test_package_remote.py 有时跑 1.6 秒、只打印一行"一、解压"就没了，
+退出码 -1。1.6 秒正好是解压 18.85 MB / 1001 个文件的时间，
+所以要确认"是不是解压这一步出的事"。
+
+每一步都 flush 打印，这样即使被杀也能看到死在哪一行。
