The immutable 5.2.2 -tag was not promoted after post-tag CI integration failures. These results are -not independent certification, a 5.2.8 result, or evidence that release assets -were published. - -| Gate | Result | Recorded evidence | -|---|---|---| -| Full project gate | PASS | `make release-check` completed successfully on `ff99770`, including the late key-file, terminal-comment, password-prompt, explicit-Bash, and scanner-limit regressions. | -| Packaging policy/syntax | PASS | `PASS=49 FAIL=0 SKIP=0`. | -| Source-only scanner adversarial suite | PASS | 39/39, including GNU thin archives, bounded archive expansion, and safe diagnostic cases. | -| Strict compilers and compiler analyzer | PASS | GCC and Clang strict builds passed; GCC `-fanalyzer` passed. | -| Static-analysis suite | PASS | 9/9 in the full tool-enabled run. A separate reduced-environment `release-check` run completed six available checks and reported `cppcheck` unavailable; unavailable tooling was not relabelled as a pass. | -| Dynamic analysis | PASS | ASan, UBSan, and LSan runs passed. | -| Mutation fuzzing | PASS | 1,000 mutation iterations completed without a sanitizer-detected crash. | - -An earlier off-screen GUI smoke run remains supporting evidence, but is not -represented as an exact-`ff99770` GUI-package result. The immutable 5.2.3 -candidate was not promoted because its source-policy test assumed LF for a -Windows `.bat` checkout that correctly used CRLF. - -## Prior 5.2.4 exact-tag integration evidence - -GitHub Actions exact-tag run `33431386002` completed 12 jobs successfully. Its -sole failed job was the openSUSE gate: the standalone `Serviceinfo` harness did -not change into the directory containing `_service` before executing the -service chain. Dependent native Windows and macOS jobs were therefore skipped, -and v5.2.4 was not promoted. The tag and its record remain immutable. - -A separate local openSUSE Tumbleweed reproduction resolved the explicit -`refs/tags/v5.2.4` revision to the tagged commit and, after -`os.chdir(service_dir)`, completed `obs_scm`, `tar`, and `recompress`. It -produced exactly one `zupt-5.2.4.tar.gz`, which passed the source-only scanner. -This isolates a release/test harness defect; it is not evidence of a product, -archive-format, cryptographic, codec, or SDK ABI change. It also does not turn -the skipped native jobs into passes or transfer any result to 5.2.8. - -## Prior 5.2.5 exact-tag native-gate evidence - -The immutable `v5.2.5` candidate was not promoted. Exact-tag GitHub Actions run -`33434986357` completed 13 jobs successfully, while its native Windows and -macOS jobs failed. The Windows regression did not preserve every requested -hostile path byte across its command-line boundary. The macOS gate exposed both -an unavailable `explicit_bzero` assumption and Bash 3.2 empty-array behavior in -the source scanner exercised by `make check`. - -The 5.2.6 corrections select the existing compiler-resistant volatile wipe on -Darwin and NetBSD, guard every relevant scanner array, and make the Windows -fixture accept explicit hexadecimal bytes, verify the full requested path in -the archive, and reject each dangerous raw byte fragment anywhere in diagnostic -output. These changes do not alter the archive format, cryptography, bundled -codec, or SDK ABI. - -A separate local compatibility run executed the corrected scanner with genuine -GNU Bash 3.2.57 in a clean clone. All four exercised modes completed: the -repository audit reported 609 files and one archive; `--tree` reported 204/0; -`--archive` reported 201/1; and `--root` plus `--tag v5.2.5` reported 810/2. -This is targeted scanner compatibility evidence only, not exact-v5.2.6 or -v5.2.8 hosted CI, package, native-platform, or promotion evidence. - -## Prior 5.2.6 exact-tag native-gate evidence - -The immutable `v5.2.6` candidate was not promoted. Exact-tag GitHub Actions run -`33442264243` completed 13 jobs successfully and failed two native jobs. On -macOS arm64, the strict SHA-NI regression build diagnosed x86-only helper -declarations as unused under `-Werror`. On Windows, argv transcoding of the safe -printable UTF-8 fixture caused the path regression to abort before its intended -archive and diagnostic assertions. - -The 5.2.7 changes scope those helper declarations to supported x86 builds and -carry the safe UTF-8 fixture across the Windows argument boundary without -locale-dependent byte conversion. These are test/release integration changes, -not archive-format, cryptographic, codec, or SDK ABI changes. - -## Prior 5.2.7 exact-tag native-gate evidence - -The immutable `v5.2.7` candidate was not promoted. Exact-tag GitHub Actions run -`33445470664` concluded `cancelled` at `2026-08-31T23:11:19Z`, with 13 -successful jobs, one failed macOS job, and one cancelled Windows job. The macOS -runner filesystem rejected creation of the -raw-C1 filename fixture with `EILSEQ`. The hosted Windows job stalled in `make -check`; a MinGW/Wine reproduction isolated the cause to -`test --password-prompt ... /dev/null || printf 1)" \ - WITH_SDK=0 WITH_PQBOX=0 -make WITH_SDK=0 WITH_PQBOX=0 check +make dist +# → /tmp/vaptvupt-5.0.0.tar.gz ``` -`WITH_SDK=1` and `WITH_PQBOX=1` use separately installed system development -libraries.

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. - - - Copyright (C) - - 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 . - -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.

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

ZKEY and ZPQK readers -validate the checksum, format version, flags, reserved bytes, exact encoded -size, and public/private role before using any key material.

The -MAC binds the encrypted payload, canonical block metadata, and the frame's -logical position, and is checked before restored data is accepted. In 5.2.2, -this positional AAD applies to DATA and DEDUP_REF frames. An authenticated -reference is bound to its own position and carries the authenticated source -position needed to verify the referenced DATA frame. +### Per-Block Authenticated Encryption -An archive-integrity trailer (AIT) covers global metadata. The 5.2.2 -`extract`, `list`, `test`, and `disk restore` paths refuse a no-AIT layout by -default, without trusting the archive's unauthenticated `ENCRYPTED` bit to -decide whether that check matters. `--allow-legacy-no-ait` is accepted only by -those commands; it is a recovery-only opt-in for a known, trusted pre-AIT -archive and emits a downgrade warning. Never use it for an archive from -untrusted or attacker-writable storage. `info` only reports unauthenticated -framing and apparent AIT presence; it does not validate the trailer or archive -contents. Plain archives use non-cryptographic checksums and do not provide -protection against an attacker who can rewrite the archive. +``` +For each data block: -Archive comments are authenticated according to the archive mode, but they are -still untrusted display data. ZUPT renders control bytes safely when showing a -comment and does not emit raw terminal-control sequences. This prevents a valid -or attacker-supplied comment from rewriting terminal output; it does not make a -plain archive cryptographically authentic. - -In new 5.2.2 encrypted+dedup archives, each reference offset is included in -the authenticated reference payload. New encrypted disk archives also -authenticate their index; the index binds the image size, block count, and a -chained XXH64 hash of the complete restored byte stream. The writer -additionally requires an XXH64 and SHA-256/128 match before emitting a dedup -reference, but that SHA-256/128 digest is an in-memory collision guard and is -not stored as an on-disk integrity claim. XXH64 is non-cryptographic: in a -plain archive it -detects accidental corruption but can be recomputed by an attacker. - -The native hybrid derivation implemented by 5.2.2 is: - -```text -ml_ss = ML-KEM-768 shared secret -x25519_ss = X25519 shared secret -hybrid_ikm = ml_ss XOR x25519_ss -archive_key = SHA3-512(hybrid_ikm || ml_ct || ephemeral_pk || - "ZUPT-HYBRID-v1") + nonce = CSPRNG(16) [16 bytes, fresh per block] + ciphertext = AES-256-CTR(enc_key, nonce, plaintext) + mac = HMAC-SHA256(mac_key, aad ‖ nonce ‖ ciphertext) [32 bytes] + stored = nonce ‖ ciphertext ‖ mac ``` -`--pq-only` derives the archive key as -`SHA3-512(ml_ss || ml_ct || "ZUPT-PQ-ONLY-v1")`. +The nonce is a **fresh 128-bit random value per block**, stored in the block +prefix and bound into the block MAC. The block sequence number is bound into +the MAC AAD (not into the nonce), so reordering, splicing, or replaying blocks +is still detected. -The native modes are at-rest archive encryption. They do not provide protocol -session forward secrecy: later compromise of the relevant long-term private key -can compromise archives encrypted to it. +> **History (fixed in 4.2.0):** earlier releases derived the nonce as +> `base_nonce XOR pad_le(block_seq, 8)`.

It -does not protect against: - -- malware, keyloggers, memory inspection, or a compromised user account on the - machine handling plaintext or keys; -- disclosure of a password or private key; -- denial of service from arbitrarily large or adversarial input; -- traffic analysis from archive size and visible framing metadata; -- hiding that a file is a ZUPT archive; -- compression-length side channels when attacker-controlled and secret data are - compressed together and an attacker can observe output length; -- network transport attacks, multi-party access control, threshold recovery, or - key rotation; -- every compiler-, microarchitecture-, power-, or speculative-execution side - channel. - -Archive entry paths reject traversal, absolute paths, control characters, -Windows alternate streams/device names, and ambiguous trailing dot/space -components. POSIX extraction resolves each parent relative to a pinned file -descriptor with no-follow semantics after canonicalizing the user-selected -output root once; symlinks below that root remain forbidden. Windows resolves -each parent and temporary -file relative to a directory handle and performs the final no-replace rename by -handle, so a checked path is not looked up again through a mutable junction or -reparse point. An existing destination leaf is never overwritten. - -Decoded bytes first go to a private, exclusively created temporary file. The -final name is published only after the expected decoded size and chained -checksum match and the stream closes successfully; failures remove the -temporary by descriptor/handle. These controls reduce traversal, link, race, -and partial-output risks, but they do not make privileged extraction -appropriate. Extract untrusted archives as a dedicated unprivileged user into -a new empty directory, inspect the result before moving it, and apply OS -sandboxing where available. - -Benchmark workspaces are random private directories. POSIX cleanup opens each -directory component without following links and removes entries relative to -pinned descriptors. Windows retains no-delete-sharing handles for the resolved -ancestors and refuses reparse-point recursion. After emptying a directory, it -reopens that entry relative to the pinned parent, verifies the volume and file -index against the traversal handle, and marks only the identity-checked handle -for deletion. An injected link is removed as a link rather than traversed to -its target. - -Disk restore has a separate destructive-device boundary. It measures and -copies the compacted archive to an exclusively created, auto-deleted private -scratch file, then performs validation and restoration from that same snapshot. -`ZUPT_TMPDIR` is an explicit existing scratch-directory override; an invalid -override fails without fallback. On POSIX, the target is opened once without -truncation or final-symlink following, classified with `fstat`, and—when it is -a supported Linux, macOS, or FreeBSD raw block device—the same descriptor is -retained through capacity checks and writes. Regular files continue through -atomic publication. Unknown device capacity, an undersized device, a -source/destination identity match, or a snapshot failure stops before the -first target write. These checks do not -make raw-device restore non-destructive: verify both operands and keep recovery -media before proceeding. - -These changes address the three 5.2.8 CodeQL High reports: #5 at SDK key -publication, #6 at POSIX disk-target classification/use, and #7 at benchmark -workspace cleanup. The regressions and source review are project evidence, not -an independent certification.

Each individual test -check now uses a no-follow descriptor with `fstat` or descriptor reads; the -static gate rejects reintroduction of path-level metadata checks there. The -subsequent C/C++ default-branch scan run `33452563116` completed successfully at -commit `7a8e5c5`; alerts #5 through #10 are fixed, and the authenticated -code-scanning API reported zero open alerts. -The final release-commit CodeQL run `33456049125` also completed successfully; -the authenticated API again reported zero open alerts, with #5 through #10 -recorded as fixed rather than dismissed. - -The Windows handle-relative implementation is scoped to normal local Win32 -paths.

Those upstream -self-audit results are not independent certification and do not transfer to -5.2.8. The immutable 5.2.3 candidate was not promoted because its source-policy -test assumed LF for a Windows `.bat` file checked out as CRLF. The immutable -v5.2.4 candidate was not promoted after exact-tag GitHub Actions run -`33431386002`: 12 jobs succeeded, the sole openSUSE job failed in its -standalone source-service harness because it did not enter the service -directory, and dependent Windows and macOS jobs were skipped. A local -Tumbleweed reproduction confirmed that `refs/tags/v5.2.4` is valid and that -`os.chdir(service_dir)` lets `obs_scm`, `tar`, and `recompress` complete with a -source-scanned archive.

The immutable v5.2.5 candidate was also -not promoted: exact-tag GitHub Actions run `33434986357` recorded 13 successful -jobs and failed native Windows/macOS jobs. Its Windows fixture-byte and macOS -secure-wipe/Bash 3.2 defects were corrected for 5.2.6.

Exact-tag v5.2.6 run `33442264243` -then completed 13 jobs successfully but failed native macOS because x86 SHA-NI -test helpers were unused on arm64 under `-Werror`, and failed native Windows -when argv transcoding aborted the safe UTF-8 fixture. Those are test-harness -integration defects, not product, archive, cryptographic, codec, or SDK ABI -changes; v5.2.6 remained unpromoted, so its results did not transfer to the -required 5.2.8 suite. The immutable v5.2.7 candidate was likewise not -promoted: exact-tag run `33445470664` concluded `cancelled` at -`2026-08-31T23:11:19Z`, with 13 successful jobs, one failed macOS job after -raw-C1 fixture creation returned `EILSEQ`, and one cancelled Windows job after -the hosted job stalled in `make check`; a MinGW/Wine reproduction isolated the -cause to a redirected password prompt entering `_getch`. Version 5.2.8 makes -both test boundaries fail or skip without hanging. Manual pre-tag run -`33452602634` subsequently passed 14 of 15 jobs, including the native macOS -DMG and the Windows source audit, build, and full distribution checks. The -remaining Windows smoke failure was an old MSYS `grep` non-BMP pattern boundary -after ZUPT had compressed and verified all inputs; MinGW/Wine confirmed ZUPT's -byte-exact UTF-8 listing. The corrected gate validates Latin-1, BMP, and -non-BMP listing bytes without locale-sensitive matching, then requires -extraction and a full tree diff. The failed run is not exact-candidate -evidence. Exact-tag run `33456209269` then completed 15/15 jobs successfully, -including native Windows/macOS, the pinned local OBS service chain, package -installation/round trips, source-only checks, analyzers, and sanitizers. -Promotion run `33457868306` published the exact 13-file allowlist after -format, metadata, payload, and checksum validation.

Key files for these + modes are produced by `vaptvupt keygen --sdk`, also SDK-only. -Textual assembly under `jasmin/` is a separate `WITH_JASMIN=1` option for -supported x86_64 compiler targets. The directory contains both generated and -separately identified hand-written assembly. Portable C is the default. -Architecture portability is a source property, not evidence that an unexecuted -architecture passed. +--- -## Assets +## What VaptVupt protects against -The assets ZUPT tries to protect are: +### 1. Confidentiality of archive contents (encrypted mode) -- archived file contents and encrypted index data; -- the integrity and ordering of encrypted archive blocks and current global - metadata covered by the archive integrity trailer; -- private keys, passwords, and derived encryption/MAC keys while held by the - trusted caller; -- safe placement of extracted entries within the requested destination. +An attacker with read access to the archive bytes cannot recover +plaintext file contents, file names, file sizes, file modes, or +embedded comments without the key/password, assuming: -The archive's existence, total byte length, magic, encryption/framing flags, and -some size/structure information are observable. Plain archives provide -corruption detection, not cryptographic protection against an active attacker. +- The chosen mode is one of the encrypted modes (`-p`, `--pq`, or the + optional `--pq-sdk` / `--pq-box`) +- The password is strong enough to resist offline brute-force + (see "Password strength" below) +- The key file (for `--pq-sdk` / `--pq-box`) was not compromised at + generation time -## Adversaries considered +### 2. Integrity of every byte of an encrypted archive -The design considers an adversary who can read, copy, truncate, reorder, or -modify stored archive bytes but cannot read the encryption endpoint's memory or -credentials. It also considers accidental corruption and malicious archive -entry paths during extraction. +If any single bit of the on-disk archive bytes is flipped, the +extraction fails with an authentication error. Coverage layers: -The following adversaries are outside the protection boundary: +- Per-block HMAC-SHA256 with frame-preface AAD (F-09): every data + block carries an HMAC over its ciphertext and over the canonical + 29-byte preface (block_type, codec_id, block_flags, sizes, + plaintext-XXH64) +- Archive Integrity Trailer (F-08): HMAC-SHA256 over the 64-byte + header and 24 bytes of footer, appended after the footer +- Strict structural validation of the encryption-header block (F-09): + codec must be `STORE`, flags must be 0, csz must equal usz, the + plaintext XXH64 must match -- malware, a keylogger, or an administrator on the source or restore endpoint; -- an attacker who obtains the password or matching private key; -- a malicious compiler, kernel, CPU, firmware, or random-number generator; -- an attacker with unrestricted side-channel observation of a shared machine; -- an attacker allowed unbounded CPU, memory, or storage denial of service. +### 3. Tamper detection on plaintext archives (best-effort) -## Security properties +Plaintext archives (no `-p`, no `--pq*`) are protected by XXH64 +plaintext checksums per block plus structural validation. This is +not cryptographic integrity — a determined attacker with write access +can produce a tampered plaintext archive that passes the checksum +(XXH64 is not collision-resistant). It does catch accidental +corruption and naive tampering. -### Encrypted archive confidentiality +Use an encrypted mode if you need cryptographic integrity. -Password and native PQ modes encrypt blocks with AES-256-CTR and authenticate -them with HMAC-SHA256. Confidentiality depends on unique nonces, correct -implementations, OS randomness, and credential secrecy. In password mode it -also depends on password entropy; PBKDF2-SHA256 slows but cannot prevent offline -guessing of a weak password. +### 4. Authentication failure indistinguishability (F-11) -Prefer `--password-prompt`, `--pass-file`, or `--pass-fd`. A password supplied -through `-p/--password` can be visible through process inspection or shell -history. A password file is protected only by the caller's filesystem choices; -ZUPT does not validate its ownership or permission bits. A descriptor is -trusted input inherited from the caller. Both non-interactive forms read one -line and reject empty, NUL-containing, or overlong values. The descriptor form -duplicates but shares the underlying stream/offset and may buffer beyond the -line, so callers should provide a descriptor dedicated to that password read. -On POSIX, handled prompt interruptions restore the saved terminal state before -termination; an exact-candidate PTY regression is required before release. -On Windows, a prompt is entered only for a real console input handle; -redirected input and console EOF fail instead of blocking in `_getch`. +The default error message for "wrong password", "wrong PQ key", +and "actual header tamper" is the same single line: -Native private-key generation uses no-replace creation with POSIX mode `0600` -or a Windows current-user-only DACL. A failed write, flush/fsync, or close leaves -the incomplete or durability-uncertain exclusive file for manual review and -removal instead of risking an unlink-after-close race against a replacement -pathname. ZKEY and ZPQK inputs -are accepted only after checksum, version, flags, reserved bytes, exact size, -and public/private role validation. This prevents role confusion and -partial/trailing-key acceptance; it does not protect a key after endpoint or -account compromise. +> `Error: Authentication failed (wrong key, wrong password, or tampered archive).` -When the optional system SDK is enabled, the in-repository adapter copies a key -through the core atomic publisher, applies POSIX mode through the already-open -temporary descriptor, and publishes only after copy/close checks succeed. Its -`sdk-test` regression preserves existing symlink/hardlink targets and verifies -private/public modes. This narrows the adapter boundary; it does not extend the -baseline assessment to the external SDK implementation. +This prevents an attacker who can issue extraction attempts from +learning which check failed first via the stderr output. Timing is +also constant (HMAC is always run, branchless return). -### Encrypted archive integrity +The detailed cause is available via `--verbose` for debugging on +machines under the user's own control. -Current encrypted archives authenticate ciphertext, canonical block metadata, -and each frame's logical position. DATA and DEDUP_REF frames both receive this -positional AAD. A reference is authenticated at its own position and carries -the authenticated source position needed to verify the referenced DATA frame, -so exchanging otherwise equivalent frames is not accepted. +### 5. Post-quantum forward secrecy (`--pq`, `--pq-only`, and optional `--pq-sdk`) -Current archives carry an archive-integrity trailer for global metadata. The -`extract`, `list`, `test`, and `disk restore` paths refuse any no-AIT layout by -default without relying on an unauthenticated header flag. -`--allow-legacy-no-ait` is a narrowly scoped, warning-producing recovery option -for those commands when the caller already trusts a pre-AIT archive. Selecting -it for attacker-controlled storage removes the header/footer authentication -assumption and is outside this threat model. `info` is an unauthenticated -framing inspection that reports apparent AIT presence but validates neither the -trailer nor archive contents. These checks do not prevent deletion of the -entire archive, rollback to an older valid archive, or storage-layer replay. +The native `--pq` mode uses ML-KEM-768 (FIPS 203 — validated byte-for-byte +against OpenSSL 3.5's ML-KEM-768; see AUDIT.md) hybridized with X25519 via an +HKDF combiner. Archives encrypted today cannot be decrypted by a future quantum +adversary holding only the ciphertext, assuming: -Archive comments remain untrusted presentation data even when they are -authenticated. Display paths render control bytes without emitting raw terminal -control sequences, limiting terminal-output injection while leaving the stored -and authenticated comment bytes unchanged. +- ML-KEM-768 retains its claimed security level (NIST Category 3, + 192-bit classical / 96-bit quantum strength) +- X25519 hybridization protects against an unforeseen ML-KEM break +- The recipient's private key is not later compromised -New 5.2.2 encrypted+dedup archives authenticate each reference offset. New -encrypted disk archives also authenticate an index that binds image size, -block count, and a chained XXH64 hash of the complete restored stream. The -writer's additional SHA-256/128 comparison is only an in-memory collision guard -before deduplication; it is not an on-disk cryptographic hash. XXH64 is not -cryptographic, so a writer who controls a plain archive can recompute it. +The native `--pq-only` mode (envelope type `0x06`) provides the same +harvest-now-decrypt-later protection using ML-KEM-768 as the *sole* key +mechanism. It exists for compliance postures that mandate a single +NIST-standardised PQ primitive with no classical KEM in the envelope +(CNSA 2.0-style "PQ-only"). **The trade-off is a loss of the second +assumption above:** there is no X25519 hybridization, so an unforeseen +break of ML-KEM-768 alone is sufficient to recover the archive key. For +that reason `--pq` (hybrid) is the recommended default, and `--pq-only` +should be used only when a policy forbids the classical component. -Plain archives use non-cryptographic checksums. A writer who controls a plain -archive can recompute them. +The optional `--pq-sdk` mode provides the same hybrid guarantee as +`--pq` via the separately distributed SDK libraries. -### Native hybrid post-quantum mode +### 6. Side-channel resistance for cryptographic primitives -The `--pq` mode combines an ML-KEM-768 shared secret and an X25519 shared secret -as implemented in 5.2.2: +The hot crypto paths (AES-256-CTR, HMAC-SHA256 comparison, X25519 +field operations, ML-KEM polynomial arithmetic) are implemented in +Jasmin and proved constant-time at the assembly level on x86_64. +Non-Jasmin platforms (aarch64, fallback x86_64) use C implementations +that avoid secret-dependent branches and memory accesses where +feasible — but without formal proof. -```text -hybrid_ikm = ml_ss XOR x25519_ss -archive_key = SHA3-512(hybrid_ikm || ml_ct || ephemeral_pk || - "ZUPT-HYBRID-v1") -``` +--- -Its goal is harvest-now/decrypt-later resistance if ML-KEM-768 remains secure, -with X25519 as a classical hedge under the combiner assumptions. This is not -session forward secrecy: compromise of the recipient's long-term private key -can compromise previously captured archives encrypted to it. +## What VaptVupt does NOT protect against -The native `--pq-only` mode removes X25519 and derives a key from ML-KEM-768 -alone. Use it only when a policy specifically excludes the classical component; -it loses the hybrid hedge. +### 1. Compromised endpoints -The in-tree ML-KEM code has project tests, including known-answer vectors and a -conditional OpenSSL 3.5 interoperability test. It has not been independently -audited or formally verified as a whole implementation. +VaptVupt cannot protect against: -### Extraction containment +- Malware on the machine doing the encryption (it sees plaintext + before any crypto is applied) +- Malware on the machine doing the extraction (it sees plaintext + after decryption) +- A hardware keylogger capturing the password +- A compromised user account that can read your files or + `~/.zupt-key` directly +- Cold-boot attacks on running machines -The reader rejects absolute paths, traversal components, control characters, -ambiguous trailing dot/space components, NTFS alternate-stream syntax, and -reserved Windows device names. POSIX extraction resolves every parent below a -pinned destination descriptor with no-follow operations after canonicalizing -the user-selected root once. Windows extraction -uses handle-relative traversal, rejects reparse-point parents, and publishes the -final name by handle without replacing an existing leaf. A checked path is not -re-resolved through a mutable parent. +If you don't trust the machine, VaptVupt cannot help. -Decoded bytes are first written to a private, exclusively created temporary -file. The final name is published only after the expected decoded size and -chained checksum match and the stream closes successfully; failures remove the -temporary through its descriptor or handle. These controls reduce traversal, -link, race, and partial-output risks, but do not establish that no parser or -filesystem bug can exist. +### 2. Key compromise -Benchmark scratch data lives in a random private directory. Cleanup resolves -POSIX components without following links and deletes relative to pinned -descriptors. On Windows it retains no-delete-sharing ancestor handles, refuses -reparse-point recursion, then reopens each emptied directory relative to its -pinned parent and verifies its filesystem identity before handle-based -deletion. An attacker who inserts a link can cause cleanup failure, but the -cleanup must not traverse to the link target. +If the password or `~/.zupt-key` is leaked: -The Windows handle-relative boundary in 5.2.8 covers normal local Win32 paths. -Win32 extended-length and device-namespace paths, raw UNC output roots, and -mapped/network-drive output are not supported. Cross-build and Wine results are -not a substitute for the required native `windows-latest` Unicode package -gate. Restore locally before moving verified output to network storage. +- All archives encrypted with that key are decryptable +- VaptVupt has no forward secrecy across archives — each archive + is encrypted under a single static key derived from the password + or stored in the key file +- There is no key-rotation feature; rotate by re-encrypting + archives under a new password/key and securely deleting the old + password/key -Disk restore copies the measured compacted archive into one exclusively -created, auto-deleted scratch file. Preflight and restoration consume that same -open snapshot. An explicit `ZUPT_TMPDIR` selects an existing scratch directory; -failure there does not fall back to consuming the mutable source pathname. On -POSIX, the destination is opened once without truncation or final-symlink -following, classified with `fstat`, and the same raw-device descriptor is -retained for supported Linux, macOS, and FreeBSD capacity checks and writes. -Regular-file output retains atomic publication. A raw target is rejected before -writing if its capacity is unknown or smaller than the image. These controls -reduce source exchange, target exchange, and immediate overrun risk but do not -protect against a compromised kernel/device, a wrongly selected sufficiently -large device, power loss, or hardware failure. +For high-value, long-term archives, treat the key file as you +would a master password: store it offline, encrypt it under +another layer (e.g. on an encrypted USB), and rotate periodically. -The SDK publication, POSIX disk-target, and benchmark-cleanup changes address -CodeQL High #5, #6, and #7 respectively. Their source review and regressions -alone are project evidence, not independent certification. Exact-tag run -`33456209269` subsequently passed all 15 hosted jobs at -`ebb9ab3aa1d42c50030ca02883f6162dc4771fe1`; final release-commit CodeQL run -`33456049125` completed successfully with zero open alerts. +### 3. Password strength -For an untrusted archive: +Password mode derives the key with PBKDF2-SHA256 (600k iterations) +in the default build, or Argon2id in a `make WITH_SDK=1` build. A +key derivation function slows offline guessing but does not make a +short, common password safe: a determined attacker with GPU clusters +or cloud compute can still exhaust a weak password. -1. use a new empty destination outside sensitive trees; -2. run as a dedicated unprivileged user, never root; -3. apply a container, sandbox, resource limits, and a storage quota when - available; -4. inspect extracted paths, types, permissions, and content before moving them; -5. never restore a disk image to a device without independently confirming both - source and destination. +Use a long, high-entropy password — a multi-word diceware passphrase +or a random 16+ character string with a full alphabet. For critical +data, use a key-file mode (native `--pq`, or the optional `--pq-sdk` +with a random key file from `vaptvupt keygen --sdk`) so the key is +CSPRNG output, not derived from human-typed text. -## Non-goals and residual risks +### 4. Metadata leakage from archive structure -ZUPT does not claim to provide: +Even with encryption, an attacker who can see the archive bytes +can infer: -- resistance to cache, power, EM, acoustic, speculative-execution, or all - compiler-introduced timing side channels; -- bounded resource consumption for every malformed archive; -- confidentiality of archive size or complete framing metadata; -- protection against compression-length oracles when secret and - attacker-controlled data are compressed together; -- rollback detection across multiple valid versions of a backup; -- forward-secure sessions, remote authentication, replay protection, or secure - transport; -- automatic key rotation, recovery, escrow, threshold access, or secure - deletion; -- preservation of every operating-system ACL, ownership attribute, extended - attribute, or special-file semantic; -- safe operation on a compromised host. +- Approximate file count (from `total_blocks` in the footer) +- Total archive size (file size on disk) +- Whether the archive is encrypted at all (`ZUPT_FLAG_ENCRYPTED` + in the global flags is visible) +- Whether the archive is solid or per-file mode (visible flag) +- Whether post-quantum mode is in use (visible flag) +- Approximate file size distribution (block sizes are visible + even when block payloads are encrypted) +- Archive creation time (a 64-bit timestamp in the header) +- A random 16-byte UUID per archive (no information leak, but + globally identifies the archive across copies) -## Credential handling +If metadata privacy matters, layer VaptVupt under another tool that +hides bulk metadata (e.g., put the `.zupt` file inside a fixed-size +encrypted container). -- Generate PQ keys on a trusted system using the OS CSPRNG. -- Keep private keys separate from the archive and from release/package inputs. -- Store an offline recovery copy and test recovery before relying on a backup. -- Use a distinct high-entropy credential where compromise isolation matters. -- Re-encrypt under a new credential after suspected disclosure; there is no - in-place key rotation. -- Never include credentials or sensitive archives in bug reports or CI logs. +### 5. Network attacks -## Supply-chain boundary +VaptVupt is not a network protocol. There is no: -Git and upstream source archives are source-only. They must pass -`scripts/check-source-only.sh` and must not contain executable code artifacts, -objects, shared/static libraries, distribution packages, unsafe symlinks, or Git -LFS pointers. +- Forward-secure session establishment (use TLS or Noise) +- Mutual authentication of remote parties (use signed messages or + TLS client certs) +- Replay protection across sessions (archives can be replayed by + an attacker who can write to the destination) +- Network-layer encryption (use TLS to transport `.zupt` files) -Nested inspection is itself an untrusted-input boundary. The release scanner -must cap recursion depth, archive members, per-entry expansion, and total -expanded bytes and fail closed when a cap is reached. Commit `ff99770` passed -all 39 source-only scanner cases, including GNU thin archives, scanner-bomb -limits, and safe diagnostic cases. +### 6. Multi-party schemes -DEB, binary RPM, SRPM, notice-bearing Linux tar.xz, source-only portable GUI -ZIP, Windows ZIP, and macOS DMG files can be published separately from the -tagged source. Each artifact extends the trust boundary to its builder, -toolchain, runner image, and packaging scripts. Treat it as validated only when -the exact target has a recorded build, content/package inspection, extracted or -installed smoke test, and applicable archive round trip. An AppImage is not -promoted for 5.2.8; bare Linux and Windows executables are also excluded. +There is no threshold cryptography, no n-of-m sharing, no +multi-party computation, no proxy re-encryption. Each archive +has exactly one decryption credential (one password OR one +recipient key). To give two people access to the same archive, +they must share the password or the key file. -For 5.2.8, that gated artifact scope covers the CLI files plus the exact GUI -DEB, noarch/source RPM, and source-only portable ZIP named in the README. The -portable ZIP contains no compiled runtime and crosses the release boundary only -after source scans and an exact safe-member check. AppDir and Flatpak bundles -and GUI platform installers remain excluded; Windows ZIP and macOS DMG outputs -remain CLI-only. +### 7. Plausible deniability / hidden volumes -The immutable, non-promoted 5.2.2 candidate at `ff99770` passed the full local -`make release-check`: packaging reported `PASS=49 FAIL=0 SKIP=0`; strict GCC, -strict Clang, GCC `-fanalyzer`, the 9/9 tool-enabled static-analysis run, -ASan/UBSan/LSan, and 1,000 mutation-fuzz iterations passed. Earlier off-screen -GUI smoke evidence is retained separately. Post-tag CI integration failures -prevented 5.2.2 promotion. This upstream self-review is not an independent -certification and is not 5.2.8 evidence. The immutable 5.2.3 candidate was not -promoted because its source-policy test assumed LF for a Windows `.bat` checkout -that correctly used CRLF. The immutable v5.2.4 candidate was not promoted after -exact-tag GitHub Actions run `33431386002`: 12 jobs succeeded, the sole openSUSE -service-harness job failed because its standalone executor did not enter the -service directory, and dependent Windows/macOS jobs were skipped. A local -Tumbleweed reproduction established that the explicit `refs/tags/v5.2.4` -revision works and that `os.chdir(service_dir)` completes the source-service -chain. This narrows the failure to release/test integration; it changes no -product, archive, cryptographic, codec, or SDK ABI boundary and supplies no -automatic 5.2.8 evidence. The immutable v5.2.5 candidate was not promoted after -exact-tag GitHub Actions run `33434986357`: 13 jobs succeeded, but native -Windows and macOS failed on fixture-byte preservation and Darwin/Bash 3.2 -portability respectively. The corresponding 5.2.6 corrections were followed by -exact-tag run `33442264243`: 13 jobs succeeded, while native macOS failed on -x86-only SHA-NI helper declarations unused on arm64 under `-Werror`, and native -Windows aborted during safe UTF-8 fixture argv transcoding. The v5.2.6 tag was -not promoted. Version 5.2.7 corrected those two boundaries, but its exact-tag -run `33445470664` concluded `cancelled` at `2026-08-31T23:11:19Z`, with 13 -successful jobs, one failed macOS job after raw-C1 filename creation returned -`EILSEQ`, and one cancelled Windows job after the hosted job stalled in `make -check`; a MinGW/Wine reproduction isolated the cause to a redirected password -prompt entering `_getch`. -The corresponding 5.2.8 fixture and prompt corrections alone did not establish -a result. Exact-tag run `33456209269` then passed 15/15 jobs, including -`sdk-test`, native Windows/macOS, the pinned local OBS source-service chain, -and the package/source gates. Promotion run `33457868306` published the exact -13 tested assets. Official authenticated OBS/Factory acceptance, the full -automatic debug-package result, and untested architectures remain unclaimed; -the earlier `debugsource` rpmlint `no-binary` finding remains unresolved and -unsuppressed. +VaptVupt archives have a fixed 6-byte magic `\x90\x5a\x55\x50\x54\x01` +at offset 0. Anyone scanning the bytes can see it's a VaptVupt +archive. VaptVupt has no hidden-volume or duress-password feature. -## Historical compatibility notes +### 8. Side channels we don't claim to address -These are historical facts about earlier releases, retained to support recovery: +- Power analysis (relevant for embedded targets, not commodity desktops) +- Electromagnetic emanation +- Acoustic side channels +- Network timing of upload patterns +- Filesystem-level metadata (mtime/atime of the `.zupt` file) -- Releases through 4.1.0 could reuse an AES-CTR nonce in encrypted `--dedup` - archives. Release 4.2.0 changed to fresh random per-block nonces. Re-encrypt - affected older archives. -- Releases through 4.2.1 used round-3 CRYSTALS-Kyber semantics in the native PQ - path. Release 5.0.0 corrected the implementation to FIPS 203 ML-KEM-768, - changing native PQ key/archive compatibility. See `CHANGELOG.md` before - planning cross-version restoration. -- Pre-AIT archive layouts now fail closed by default. The explicit - `--allow-legacy-no-ait` read option is only for recovery from a known, trusted - historical archive and leaves its header/footer metadata outside the current - authenticated boundary. -- The 5.2.2 reader retains compatibility parsers for the fixed-width disk index - and encrypted-dedup linear AAD sequence published through 5.2.1. An actual - v5.2.1 password-encrypted DATA/DATA/REF/DATA disk fixture is stored as hexadecimal - text with source and hash provenance. The candidate lists, tests, extracts, and restores - it byte-exact, with a warning that the legacy index has no whole-image hash; - the full local Linux gate passed on commit `ff99770`. Older readers are not - claimed to accept new flag-gated 5.2.2 records, and untested historical mode - combinations remain unclaimed. +### 9. Trusted setup of post-quantum primitives -Historical test counts in the changelog describe those releases. They do not -automatically become 5.2.8 results; current outcomes belong in the release -validation record, with unavailable environments marked `SKIP`. In particular, -runs made before the final positional-AAD and mandatory-AIT changes are not -final release gates for the resulting candidate. +The in-tree ML-KEM-768 implementation was not independently audited +at the time of writing. We use NIST KAT vectors for correctness +verification but have not formally proven constant-time properties +for every PQ code path. + +For maximum assurance, treat the post-quantum layer as a hedge — it +does not replace the X25519 layer; both must be broken for an +attacker to recover plaintext. + +### 10. Format extension attacks + +The format is versioned (v1.6). Older readers may accept newer +archives in unexpected ways. We try to maintain forward +compatibility, but a careful attacker who can produce +malformed-but-just-valid archives may find parser-state issues that +don't rise to the level of a CVE. The fuzzing harness +(`make fuzz-format`) is the primary mitigation; report bugs. + +### 11. Compression-side-channel attacks (CRIME / BREACH style) + +VaptVupt compresses before encryption. If an attacker can: + +- Influence part of the plaintext (e.g. inject a known prefix) +- Observe the resulting archive size precisely + +then they can use the compression ratio to learn information about +the rest of the plaintext — this is the classic CRIME/BREACH attack +against TLS compression. + +VaptVupt is designed for offline backup, where attacker-controlled +plaintext injection is rare. If your threat model includes +attacker-chosen plaintext mixed with secret plaintext in the same +archive, use `--no-compress` (codec 0 = STORE) to disable the +LZ codec and eliminate this side channel. + +--- + +## Cryptographic assumptions + +VaptVupt's security rests on the following standard assumptions: + +| Assumption | What breaks if it fails | +|---|---| +| AES-256-CTR is a secure stream cipher | All encrypted archives become readable | +| HMAC-SHA256 is a secure PRF / MAC | Tamper detection fails; integrity can be forged | +| PBKDF2-SHA256 (or Argon2id, WITH_SDK) is a secure password KDF | Password-mode archives become brute-forceable faster | +| ML-KEM-768 retains NIST Category 3 security | `--pq` / `--pq-sdk` reduce to the X25519 layer; **`--pq-only` has no fallback and is broken** | +| X25519 retains 128-bit security (no quantum) | Hybrid PQ modes reduce to the ML-KEM layer; `--pq-only` and classical password mode unaffected | +| HKDF-SHA256 is a secure key-derivation construction | Combined PQ + classical keys may be predictable | +| SHA3 / SHAKE retain pre-image and collision resistance | Auxiliary protocol bindings may be forged | + +If you don't trust one of these primitives, VaptVupt cannot protect +you.

SYNOPSIS +.B vaptvupt-gui +.RI [ ARCHIVE ] +.SH DESCRIPTION +.B vaptvupt-gui +is a graphical frontend for +.BR vaptvupt (1). +It provides tabs for compression, extraction, key management, and +full-disk backup. Both PQ encryption modes are exposed: +.B legacy --pq +and +.B SDK v2 --pq-sdk +(HKDF combiner, key commitment, HPKE binding, Argon2id). + +The legacy command name +.B zupt-gui +is preserved as a symlink for backward compatibility; both invocations +behave identically. + +If +.I ARCHIVE +is given on the command line, the GUI opens directly on the +extract tab with that archive preloaded. + +.B vaptvupt-gui +uses Qt 6. It works with either of the following Python Qt bindings, +auto-detected at startup in this order: +.IP \(bu 2 +PySide6 (Qt for Python) +.IP \(bu 2 +PyQt6 +.PP +If neither is installed, the GUI prints an instructive error and exits. + +.SH TABS +.TP +.B Compress +Select files or directories, choose codec, level, password and/or PQ +key.

The product was renamed from +.B Zupt +to +.B VaptVupt +in v3.0.0 because of a prior INPI Brasil trademark registration of the +name "Zupt" for unrelated software.

For -.B compress -and -.BR "disk backup" , -the interactive form asks for confirmation. -. -.TP -.BR -p " " password , " --password " password -Read a password directly from the next process argument. This is compatible -with older command lines but can expose the password through shell history or -process inspection. Prefer one of the non-argv forms below. -. -.TP -.B --password-prompt -Read the password from the terminal without echo. This explicit form avoids -the optional-argument ambiguity of historical -.BR -p . -On POSIX, handled interruptions restore the terminal settings saved before the -prompt. -. -.TP -.BI --pass-file " file" -Read the first line from -.IR file . -The trailing LF and an optional preceding CR are removed. Empty input, an -embedded NUL, or an overlong password is rejected. Protect the file with -restrictive permissions and remove it securely when it is no longer needed. -. -.TP -.BI --pass-fd " fd" -Read the first line from the inherited numeric file descriptor -.IR fd . -ZUPT duplicates the descriptor for reading and does not close the caller's -original descriptor. The duplicate shares the underlying stream and offset; -buffered input may consume beyond the password line, so dedicate the descriptor -to this read. The same input validation as -.B --pass-file -applies. -. -.SH COMPRESSION OPTIONS -These options are accepted by -.B compress -unless stated otherwise. -. -.TP -.BR -l " " 1..9 , " --level " 1..9 -Set the compression level. The default is 7. Automatic block sizes are 128 KiB -for levels 1-2, 1 MiB for levels 3-4, 2 MiB for levels 5-6, 4 MiB for level 7, -and 8 MiB for levels 8-9. Deduplication uses a smaller automatic granularity. -. -.TP -.BR -b " " bytes , " --block " bytes -Set the block size in bytes. Values are constrained to the supported range of -64 KiB through 256 MiB. -. -.TP -.BR -s , " --store" -Store data without compression. -. -.TP -.BR -f , " --fast" -Select the fast LZ codec. -. -.TP -.BR --vv , " --vaptvupt" -Force the bundled VaptVupt LZ plus ANS codec. -. -.TP -.B --lzhp -Force the portable LZHP codec. -. -.TP -.BI --kdf " algorithm" -Select the password KDF. The default source-only build supports and defaults to -.BR pbkdf2 , -using PBKDF2-SHA256 with 600,000 iterations. A -.B WITH_SDK=1 -build additionally supports -.B argon2id -and uses it by default. A build must reject a requested KDF that it cannot -provide rather than silently changing algorithms. -. -.TP -.BR -c " " text , " --comment " text -Store a comment of up to 4095 CLI bytes. In an encrypted archive the comment is -encrypted and authenticated with the archive; in a plain archive it receives -only the plain archive's non-cryptographic integrity treatment. -. -.TP -.BI --comment-file " file" -Read the comment from -.IR file . -Trailing CR/LF characters are removed. -. -.TP -.BR -D , " --dedup" -Enable block-level deduplication. Encrypted deduplicated blocks still use fresh -per-block nonces in current archives. DATA and DEDUP_REF frames are bound to -their logical positions. An authenticated reference also carries the source -position required to authenticate the referenced DATA frame. -. -.TP -.BR -S , " --solid" -Use one solid compression stream. Solid mode is single-threaded. -. -.TP -.BR -y , " --force" -Allow -.B compress -to overwrite an existing output whose name does not end in -.BR .zupt . -This does not relax extraction's no-overwrite policy. -. -.TP -.BR -t " " count , " --threads " count -Set the compression or extraction thread count. Zero selects automatic -detection; explicit values are limited to 64. This option is accepted by -.B compress -and -.BR extract , -and by disk backup/restore, but not by -.B list -or -.BR test . -. -.TP -.BR -v , " --verbose" -Enable additional progress or diagnostic output where the selected command -implements it. Authentication failures remain intentionally generic unless -verbose diagnostics are requested, reducing the default verbal probe-oracle. -. -.SH POST-QUANTUM OPTIONS -.TP -.BI --pq " key" -Use the native hybrid envelope: ML-KEM-768 plus X25519 with the archive-key -combiner documented in -.BR THREAT_MODEL.md . -Use the recipient public key for creation and the matching private key for -reading. This is the recommended native PQ mode. -. -.TP -.BI --pq-only " key" -Use native ML-KEM-768 without the X25519 hedge. Choose it only when a policy -requires a single post-quantum KEM. Its keys are generated with -.BR "zupt keygen --pq-only" . -. -.TP -.BI --pq-sdk " key" -Use the optional system -.B libvuptsdk -integration. This option is unavailable unless ZUPT was built with -.BR WITH_SDK=1 . -It is not enabled by the default source-only distribution build. -. -.TP -.BI --pq-box " key" -Use the optional system -.B libpqvaptvupt -sealed-box integration. This option is unavailable unless ZUPT was built -with -.BR WITH_PQBOX=1 . -It is not enabled by the default source-only distribution build. -. -.SH EXTRACTION OPTIONS -.TP -.BR -o " " directory , " --output " directory -Extract below -.IR directory . -The directory is created when needed. The default is the current directory. -. -.PP -Extraction also accepts the password, PQ, -.BR -v , -and -.B -t -options described above. Unlike compression, extract/list/test options may -appear before or after the single archive operand. -. -.SH TRUSTED LEGACY READ OPTION -.TP -.B --allow-legacy-no-ait -Permit recovery of a known, trusted historical archive that predates the -archive-integrity trailer. By default the validating read commands reject an -archive without an AIT, without trusting its unauthenticated header flags. This -option emits a downgrade warning and is accepted only by -.BR extract , -.BR list , -.BR test , -and -.BR "disk restore" . -It is rejected by compression and disk backup, which always write a current -trailer. -. -.PP -Do not use this option for an archive obtained from untrusted or -attacker-writable storage. It does not authenticate the legacy header or footer. -After recovery, verify the restored data and create a new current archive. -. -.SH DISK OPTIONS -Disk options must precede the archive and device/file operands. Both disk -subcommands accept -.BR -l / --level , -.BR -b / --block , -.BR -s / --store , -.BR --vv / --vaptvupt , -.BR --lzhp , -the password input options, -.BR --pq , -.BR --pq-only , -.BR -D / --dedup , -.BR -c / --comment , -.BR --comment-file , -.BR --kdf , -.BR -t / --threads , -and -.BR -v / --verbose . -The optional SDK/PQBOX envelope options and solid mode are not disk-command -options. -. -.PP -.B --allow-legacy-no-ait -is accepted by disk restore only. -. -.SH KEY GENERATION OPTIONS -.TP -.BR -o " " file , " --output " file -Write the generated private key or exported public key to -.IR file . -This option is required. -. -.TP -.BR --pub -Export a public key from the private key selected by -.BR -k . -Use the same mode option as the private key. -. -.TP -.BR -k " " file , " --key " file -Read the source private key used by -.BR --pub . -. -.TP -.BR --pq-only , " --pqonly" -Generate or export a native ML-KEM-768-only key. -. -.TP -.BR --sdk , " --pq-sdk" -Generate an SDK-format key through the optional -.B libvuptsdk -integration. -. -.TP -.BR --box , " --pq-box" -Generate a sealed-box key through the optional -.B libpqvaptvupt -integration. -. -.PP -With no mode option, -.B keygen -generates or exports the native ML-KEM-768 plus X25519 hybrid format used by -.BR --pq . -.PP -Private-key output uses no-replace creation, POSIX mode 0600, or a Windows -current-user-only DACL. A write, flush, or close failure leaves the invalid -exclusive partial for manual removal rather than unlinking a possibly replaced -pathname. Native ZKEY and ZPQK inputs must have a valid checksum, version, -flags, reserved bytes, exact size, and public/private role; malformed or -role-confused keys are rejected. -. -.SH SECURITY NOTES -Use encrypted archives when an attacker may modify storage. Plain checksums are -not authentication. Keep private keys separate from archives, use high-entropy -passwords, and prefer -.BR --password-prompt , -.BR --pass-file , -or -.B --pass-fd -over argv passwords. -.PP -Archive comments remain untrusted display data even when authenticated. ZUPT -renders control bytes without emitting raw terminal-control sequences. -. -.PP -Extract untrusted archives as a dedicated unprivileged user into a new empty -local directory. POSIX builds canonicalize the user-selected output root once, -then traverse below a pinned directory descriptor with no-follow operations. -Windows builds use handle-relative traversal and -no-replace publication for normal local Win32 destinations. Extended-length and -device-namespace paths, raw UNC output roots, and mapped/network-drive output -are not supported in 5.2.8. Cross-compilation and Wine results are not native -Windows evidence; the native Windows package gate, including its Unicode round -trip, is separate and mandatory before publication. -. -.PP -Current encrypted archives protect ciphertext, canonical framing metadata, -logical frame position, and current header/footer metadata. The default AIT -requirement prevents a silent downgrade to a trailerless layout; the explicit -legacy override intentionally leaves old header/footer metadata outside that -authenticated boundary. ZUPT does not protect a compromised endpoint, a -disclosed credential, archive rollback or deletion, traffic analysis, -compression-length side channels, or every compiler and microarchitectural side -channel.

The 5.2.2 reader reconstructs the legacy linear block-AAD sequence, -lists, tests, extracts, and restores its input byte-exact through the -fixed-width legacy disk-index parser. This does not cover every historical mode -and passed in the full local Linux gate for commit `ff99770`; the target RPM -`%check` must still exercise it before that package is promoted. - -Disk restore also snapshots the measured archive into a private scratch file -before opening the destination, then validates and restores from that same -stream. An invalid `ZUPT_TMPDIR` override (or the compatibility fallback -`VAPTVUPT_TMPDIR`) and an unknown or insufficient raw-device capacity fail -before the first target write.

Exact-tag GitHub Actions run -`33431386002` recorded 12 successful jobs and one failed openSUSE job.

With `osc` 1.27.3, -`obs-service-obs_scm` 0.12.4, `obs-service-tar` 0.12.4, and -`obs-service-recompress` 0.5.2 installed, the same executor completed -`obs_scm`, `tar`, and `recompress` after `os.chdir(service_dir)`.

It does not change the product, archive format, -cryptography, codec, or SDK ABI; it does not make skipped native jobs pass or -establish authenticated OBS/Factory acceptance. No v5.2.4 evidence transferred -automatically to v5.2.8; the exact candidate later repeated every applicable -upstream gate in run `33456209269`, as recorded below. The automatic openSUSE -`debugsource` rpmlint `no-binary` finding remains unresolved and unsuppressed. - -## Prior 5.2.5 exact-tag native-gate evidence - -The immutable v5.2.5 candidate was not promoted. Exact-tag GitHub Actions run -`33434986357` completed 13 jobs successfully and failed the native Windows and -macOS jobs. Windows exposed a hostile-path fixture that did not preserve its -requested bytes across the command-line boundary; macOS exposed the unsupported -`explicit_bzero` assumption and Bash 3.2 empty-array handling. The 5.2.6 -corrections address those release/test integration defects without an archive, -cryptographic, codec, or SDK ABI change. - -## Prior 5.2.6 exact-tag native-gate evidence - -The immutable v5.2.6 candidate was not promoted. Exact-tag GitHub Actions run -`33442264243` completed 13 jobs successfully and failed two native jobs. The -macOS arm64 SHA-NI test build treated unused x86-only helper declarations as -errors under `-Werror`; Windows argv transcoding aborted the safe printable -UTF-8 fixture before its intended path assertions. The 5.2.7 changes correct -those test-harness boundaries without an archive-format, cryptographic, codec, -or SDK ABI change. They do not establish 5.2.8 hosted, native, OBS, or promotion -evidence. - -## Prior 5.2.7 exact-tag native-gate evidence - -The immutable v5.2.7 candidate was not promoted. Exact-tag GitHub Actions run -`33445470664` concluded `cancelled` at `2026-08-31T23:11:19Z`, with 13 -successful jobs, one failed macOS job, and one cancelled Windows job. macOS -rejected creation of the raw-C1 scanner fixture -with `EILSEQ`; the hosted Windows job stalled in `make check`, and a MinGW/Wine -reproduction isolated the cause to a redirected password prompt entering -`_getch`. Version 5.2.8 makes those test -boundaries fail or skip without hanging, addresses CodeQL High #5/#6/#7 in SDK -key publication, disk restore, and benchmark cleanup, and adds `sdk-test` to -release and hosted Linux gates. None of those changes establishes an exact -5.2.8 OBS, native, hosted-CI, or promotion result. - -## 5.2.8 exact-tag upstream package evidence - -Manually dispatched exact-tag GitHub Actions run `33456209269` passed all 15 -jobs at `ebb9ab3aa1d42c50030ca02883f6162dc4771fe1`. Its openSUSE Tumbleweed -x86_64 job parsed and normalized the spec, executed the pinned standalone OBS -source-service chain, source-scanned the resulting archive, built the binary -RPM and genuine SRPM, ran `rpmlint` without suppressions, and completed the -install/round-trip/uninstall test. The canonical source archive is 798296 bytes -with SHA-256 -`378b9506211545b9594cf0d38ac8955d9b1cac34eb6b379ae0ec26b84edb65f7`. - -Promotion run `33457868306` published the exact tested binary RPM and SRPM with -the other gated assets. The source package is identified by -`%{SOURCEPACKAGE}=1` and an absent `%{SOURCERPM}`; its `%{ARCH}` legitimately -reflects the spec's build architecture and is not the SRPM discriminator. -Repository, Git archive, and upstream source tarball scans remain binary-free. - -This is upstream local-service and package evidence, not a claim that the -package was submitted to or accepted by openSUSE Factory, nor a result for the -full set of automatically generated OBS debug packages or any untested -architecture. - -## Prior openSUSE packaging validation - -The local results below were produced on 2026-08-24 from the 5.2.2 candidate -snapshot captured for the packaging run, in a disposable openSUSE Tumbleweed -20260822 x86_64 container.
