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

 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:
    <program>  Copyright (C) <year>  <name of author>
    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.

 # uce
-Udo's C++ Entry Points
+## Current State
 This is in the early stages of development. Don't use this for anything important (or at all)!
 ## Overview
 UCE is a PHP-inspired server-side runtime that lets you build web pages and handlers in C++ using a small `.uce` preprocessor plus a FastCGI application server.
 - `.uce` pages compile to shared objects on demand
 - normal HTTP pages expose `RENDER(Request& context)`
 - WebSocket pages can additionally expose `WS(Request& context)`
 - local CLI/admin/test entrypoints can expose `CLI(Request& context)` and are invoked through the Unix CLI socket
 - sub-rendering and components pass structured data through `context.props`
 - nginx can forward normal `.uce` requests and ordinary `.ws.uce` page loads to the FastCGI socket, while real WebSocket upgrade requests for `.ws.uce` endpoints go to the built-in HTTP/WebSocket listener
 - the nginx-published application tree lives under `site/`
 - you can include C++ code as much as you want, but only .uce files called via API functions and entry points will be pre-processed
 - the preprocessor has two jobs:
       - allow for inline HTML within C++ and the use of templating tags inside of that HTML
       - convenience directive and macro parsing so UCE files don't need a lot of boiler plate
 The abolition of boilerplate was a major design factor, resulting in a page as small as this:
 ```uce
 RENDER(Request& context)
 {
       <>hello world</>
 }
 ```
 The runtime is still experimental.
 ## Build
 Build the runtime with:
 ```bash
 bash scripts/build_linux.sh
 ```
 The current build expects:
 - `clang++`
 - `mysql_config`
 - PCRE2 development headers and library (`libpcre2-dev` on Debian / Ubuntu)
 - standard Linux development headers for `dl`, `pthread`, sockets, and backtrace support
 SQLite is vendored under `src/3rdparty/sqlite/` and compiled by `scripts/build_linux.sh`; no system SQLite package is required.
 The binary is written to:
 ```bash
 bin/uce_fastcgi.linux.bin
 ```
 ## Runtime Model
 UCE pages use explicit request handlers instead of implicit globals:
 - `RENDER(Request& context)` for normal HTTP rendering
 - `WS(Request& context)` for inbound WebSocket messages
 - `CLI(Request& context)` for local command-line/admin/test invocations through `CLI_SOCKET_PATH`
 Useful related runtime patterns:
 - `unit_render(String file_name)` or `unit_render(String file_name, Request& context)` to invoke another page
 - `context.cfg` for request-local structured configuration
 - `context.props` for invocation-local structured input such as component props
 - `context.connection` for broker-owned per-WebSocket-connection state shared across `WS(Request& context)` calls
 - `context.params["UCE_CLI"] == "1"` while handling a local CLI socket request
 - `context.in` for the current request body, including the current WebSocket message payload inside `WS(Request& context)`
 - `context.params["WS_..."]` for direct WebSocket message metadata on the request parameter map
 - `context.params`, `context.get`, `context.post`, `context.cookies`, `context.session`, and `context.header` for request/response state
 - `context.set_status(code[, reason])` to set the HTTP response status
 Useful helpers for that data model include:
 - `DValue::get_by_path("a/b/c")` for path-style config traversal without creating missing keys
 - `DValue::has("key")` / `key("key")` for non-mutating child lookup, and `get_or_create("key")` when creation is intended
 - `DValue::to_u64()`, `to_s64()`, `to_f64()`, `to_bool()`, and `to_stringmap()` for typed reads from structured values
 - `json_encode(String)` for emitting JavaScript-safe string literals directly
 - `ascii_safe_name(String)` for conservative ASCII identifier normalization
 - `path_join(base, child)` for filesystem-style path assembly
 - `sqlite_connect()`, `sqlite_query()`, and related helpers for embedded SQLite storage with named prepared parameters
 - `zip_create()`, `zip_list()`, `zip_read()`, and `zip_extract()` for minimal ZIP archive workflows
 - `gz_compress()` and `gz_uncompress()` for gzip-format byte strings
 - `server_start_http()` / `server_stop()` for runtime-managed custom HTTP listeners backed by `SERVE_HTTP` handlers
 - `map()`, `filter()`, `list_unique()`, `dv_filter()`, `dv_map()`, `dv_pick()`, and related helpers for route/menu/card data shaping near render code
 Named component handlers are also supported:
 ```cpp
 COMPONENT:BODY(Request& context)
 {
 	<>
 		<p><?= context.props["body"].to_string() ?></p>
 	</>
 }
 ```
 Those are intended for sub-rendering through helpers such as `component("components/card:BODY", props, context)` rather than direct page entry.
 Additional lifecycle hooks are also available on ordinary `.uce` units:
 - `INIT(Request& context)` runs once when a worker loads that unit's shared object into memory
 - `ONCE(Request& context)` runs once per request before the first `RENDER()`, `CLI()`, or `COMPONENT...` entrypoint from that file
 CLI units can be invoked locally with the convenience wrapper or directly over HTTP-over-Unix:
 ```bash
 scripts/uce-cli /tests/cli.uce action=echo message=hello
 scripts/uce-cli --json '{"action":"echo","message":"hello"}' /tests/cli.uce
 curl --unix-socket /run/uce/cli.sock http://localhost/tests/cli.uce
 ```
 For structured CLI commands, prefer JSON POST bodies and read them with `cli_input(context)`.
 ## Template Output
 UCE treats template parsing as one shared code-vs-literal state machine.
 - `<>` and `?>` both enter literal output mode
 - `</>` and `<?` both return to code mode
 - the delimiter pairs are interchangeable, so either style can be used consistently or mixed locally
 Inside literal output, UCE supports three inline forms:
 - `<? ... ?>` to emit raw C++ statements
 - `<?= expression ?>` to print HTML-escaped output
 - `<?: expression ?>` to print unescaped output
 Use `<?= ... ?>` by default for user-visible text. Use `<?: ... ?>` only for trusted markup or content that has already been escaped.
 The parser treats C++ `//` and `/* ... */` comments as comments in both normal code and `<? ... ?>` islands, so quotes or delimiter markers inside comments do not confuse template parsing.
 The preprocessing implementation is split between `src/lib/compiler.cpp` and `src/lib/compiler-parser.cpp`. `compiler.cpp` owns unit compilation and cache orchestration, while `compiler-parser.cpp` owns source rewriting and template parsing.
 ## Components
 UCE includes a native component layer built on top of ordinary `.uce` files:
 - `component(name[, props[, context]])`
 - `component_render(name[, props[, context]])`
 - `component_exists(name)`
 - `component_resolve(name)`
 Component props are passed through `context.props`.
 Component names resolve:
 1. as the exact file name you supplied
 2. as that same name plus `.uce`
 3. as those same two forms under `components/`
 When you want returned component markup inside a literal block, prefer:
 ```cpp
 <>
 	<div class="panel"><?: component("components/card", props, context) ?></div>
 </>
 ```
 because `<?= ... ?>` HTML-escapes the returned markup. For direct output from C++ code, use `component_render(...)`.
 Components expose `COMPONENT(Request& context)` as their default entrypoint and may expose additional named handlers with `COMPONENT:NAME(Request& context)`.
 The component helpers call only `COMPONENT...` handlers. A file meant purely for component use can define `COMPONENT()` without defining `RENDER()`, which keeps direct page entry and component entry cleanly separated. Inside a component file, `component(":NAME", props, context)` and `component_render(":NAME", props, context)` target another named component handler in that same file.
 If the component file also defines `ONCE(Request& context)`, that hook runs once per request before the file's first component/render entrypoint. If it defines `INIT(Request& context)`, that hook runs once when the worker loads the unit.
 ## WebSockets
 The runtime keeps the socket lifecycle in-process and exposes a low-boilerplate API to page code:
 - `ws_message()`
 - `ws_connection_id()`
 - `ws_scope()`
 - `ws_opcode()`
 - `ws_is_binary()`
 - `ws_connections([scope])`
 - `ws_connection_count([scope])`
 - `ws_send(message[, binary[, scope]])`
 - `ws_send_to(connection_id, message[, binary])`
 - `ws_close([connection_id])`
 By default, the WebSocket scope is the current page file, so `ws_send()` queues a message for clients connected to that same `.ws.uce` endpoint.
 Each live WebSocket connection owns a broker-side `DValue` exposed to page code as `context.connection`. Mutations to that tree persist for the life of the socket and are visible on later `WS(Request& context)` calls for the same client.
 The current inbound payload is available directly as `context.in`, and the runtime mirrors message metadata into `context.params` using keys such as `WS_CONNECTION_ID`, `WS_SCOPE`, `WS_CONNECTION_COUNT`, `WS_OPCODE`, `WS_MESSAGE_TYPE`, and `WS_DOCUMENT_URI`.
 `ws_message()` may still be used when you want the payload through a helper API. Use `ws_opcode()` / `ws_is_binary()` to inspect the current inbound message type.
 Set `binary = true` on `ws_send()` or `ws_send_to()` to queue a binary frame instead of a text frame.
 The runtime accepts fragmented messages, validates reserved bits and UTF-8 for text payloads, and delivers both text and binary message frames into `WS(Request& context)`.
 ## Error Reporting
 Unhandled exceptions and recovered fatal request signals return a `500 Internal Server Error` response with a plain-text trace instead of simply dropping the upstream connection and leaving nginx to show a generic `502`.
 The demo page `site/test/error-reporting.uce` can be used to exercise:
 - uncaught exception handling
 - recovered `SIGABRT`
 - recovered `SIGSEGV`
 The current error page includes:
 - request URI
 - resolved script path
 - generated C++ path when available
 - high-level error summary
 - source/generated excerpts and raw compiler output paths for template/component/unit failure modes
 - signal number and name when applicable
 - a native backtrace
 Compile failures are also formatted with the source path, generated C++ path, compile-output artifact path, a nearby source/generated excerpt when a line can be identified, and the raw compiler output.
 This recovery path currently covers normal request handling. It is not yet the universal recovery path for every runtime subsystem.
 ## Docs And Tests
 The most current user-facing reference lives under `site/doc/`, and the demo pages live under `site/test/`. Developers coming from React, Next, or Remix should start with `site/doc/pages/coming_from_react.txt` / `/doc/index.uce?p=coming_from_react` for the concept map and starter-router notes.
 Useful entry points:
 - repo files:
  - `site/doc/index.uce`
  - `site/doc/singlepage.uce`
  - `site/test/index.uce`
 - published URLs:
  - `/doc/index.uce`
  - `/doc/singlepage.uce`
  - `/test/index.uce`
 Representative test pages:
 - `site/test/components.uce`
 - `site/test/websockets.ws.uce`
 - `site/test/error-reporting.uce`
 - `site/test/post-multipart.uce`
 - `site/test/session.uce`
 ## Deploy Behind Nginx
 The intended production shape is:
 - nginx serves static files directly
 - nginx forwards `.uce` requests and ordinary `.ws.uce` page loads to the UCE FastCGI Unix socket
 - nginx proxies actual WebSocket upgrade requests for `.ws.uce` endpoints to the runtime's built-in HTTP/WebSocket listener
 - systemd keeps the runtime built, started, and restarted on failure
 The repository ships the pieces used for this:
 - `scripts/systemd/uce.service`
 - `scripts/systemd/manage-uce-service.sh`
 - `etc/uce/settings.cfg`
 ### 1. Install build and runtime dependencies
 On a Debian or Ubuntu host, start with the packages needed to build and run UCE behind nginx:
 ```bash
 apt update
 apt install -y nginx clang mariadb-client libmariadb-dev libpcre2-dev build-essential
 ```
 The exact package names may vary by distro. The important requirements are:
 - `nginx`
 - `clang++`
 - `mysql_config`
 - PCRE2 development headers and library (`libpcre2-dev` on Debian / Ubuntu)
 - normal Linux development headers for threads, sockets, `dl`, and backtrace support
 ### 2. Put the repo on the server
 This README assumes the repository lives at:
 ```bash
 /Code/uce.openfu.com/uce
 ```
 That is what the shipped `scripts/systemd/uce.service` file currently uses as its `WorkingDirectory` and build path. If you deploy somewhere else, update that unit file before enabling the service.
 ### 3. Configure `/etc/uce/settings.cfg`
 The runtime reads its server settings from:
 ```bash
 /etc/uce/settings.cfg
 ```
 The shipped example contains the important filesystem and FastCGI settings:
 ```ini
 BIN_DIRECTORY=/var/cache/uce/work
 TMP_UPLOAD_PATH=/var/lib/uce/uploads
 SESSION_PATH=/var/lib/uce/sessions
 FCGI_SOCKET_PATH=/run/uce/fastcgi.sock
 FCGI_PORT=9993
 PRECOMPILE_FILES_IN=
 SITE_DIRECTORY=site
 PROACTIVE_COMPILE_CHECK_INTERVAL=60
 WORKER_COUNT=4
 MAX_MEMORY=16777216
 SESSION_TIME=2592000
 ```
 For nginx deployments, the most important setting is:
 - `FCGI_SOCKET_PATH=/run/uce/fastcgi.sock`
 That is the Unix socket nginx should use for normal `.uce` requests.
 `FCGI_PORT` is optional if nginx is talking to the Unix socket. Leave it set if you also want a TCP FastCGI listener, or remove it if you want the socket to be the only FastCGI entry point.
 If you want WebSocket support through nginx, also make sure the built-in HTTP listener is available. The runtime currently defaults `HTTP_PORT` to `8080` even if it is not present in the config file, but it is clearer to set it explicitly:
 ```ini
 HTTP_PORT=8080
 ```
 Proactive compilation settings:
 - `SITE_DIRECTORY=site` tells the runtime which tree to scan on startup for `.uce` files when `PRECOMPILE_FILES_IN` is left empty.
 - `PRECOMPILE_FILES_IN=` can override that startup scan root with a different absolute or runtime-relative directory.
 - `PROACTIVE_COMPILE_CHECK_INTERVAL=60` controls how often the low-priority background compiler rechecks known `.uce` files for stale or missing shared objects.
 The runtime keeps a shared known-file registry under `BIN_DIRECTORY` and updates it as request handling discovers new `.uce` files, so proactive recompiles are not limited to the initial startup scan.
 Recommended deployment notes:
 - keep `HTTP_PORT` bound to localhost only at the firewall or by network policy; nginx should be the public entry point
 - keep `BIN_DIRECTORY`, `TMP_UPLOAD_PATH`, and `SESSION_PATH` on writable local storage
 - after editing `/etc/uce/settings.cfg`, restart `uce.service`
 ### 4. Install and enable the systemd service
 As root, from the repository root:
 ```bash
 scripts/systemd/manage-uce-service.sh setup
 ```
 That script:
 - installs `scripts/systemd/uce.service` as `/etc/systemd/system/uce.service`
 - installs `etc/uce/settings.cfg` to `/etc/uce/settings.cfg` if it does not already exist
 - reloads systemd
 - enables the service at boot
 - starts the runtime immediately
 Useful follow-up commands:
 ```bash
 scripts/systemd/manage-uce-service.sh status
 scripts/systemd/manage-uce-service.sh restart
 scripts/systemd/manage-uce-service.sh logs 200
 ```
 The unit currently:
 - uses systemd-managed runtime/state/cache roots under:
  - `/run/uce`
  - `/var/lib/uce`
  - `/var/cache/uce`
 - prepares:
  - `/var/cache/uce/work`
  - `/var/lib/uce/uploads`
  - `/var/lib/uce/sessions`
 - removes any stale `/run/uce/fastcgi.sock`
 - rebuilds the runtime before start
 - runs the binary from the repo root so `COMPILER_SYS_PATH` resolves correctly
 ### Debian package build
 To build a Debian package from the repository root:
 ```bash
 bash scripts/make_deb.sh 0.1.2
 ```
 That script:
 - rebuilds the runtime first
 - stages the current runtime tree under `/usr/lib/uce`
 - installs `/etc/uce/settings.cfg` as a package conffile
 - installs a packaged `uce.service` under `/lib/systemd/system/`
 - writes Debian maintainer scripts for systemd reload/enable handling
 - follows a more PHP-like/FHS deployment shape with immutable runtime files under `/usr/lib`, config under `/etc`, cache/state under `/var`, and the FastCGI socket under `/run/uce/`
 ### 5. Configure nginx for `.uce` and `.ws.uce`
 You need two nginx paths for `.ws.uce` endpoints:
 - FastCGI for ordinary `.uce` requests and plain `.ws.uce` page renders
 - HTTP proxying only for actual WebSocket upgrade traffic on `.ws.uce` endpoints
 If you use WebSockets, add this `map` in the nginx `http` block:
 ```nginx
 map $http_upgrade $connection_upgrade {
 	default upgrade;
 	''      close;
 }
 ```
 Then use a server block along these lines:
 ```nginx
 server {
 	listen 80;
 	server_name example.com;
 	root /Code/uce.openfu.com/uce/site;
 	index index.uce index.html;
 	location / {
 		try_files $uri $uri/ =404;
 	}
 	location ~ \.uce$ {
 		include fastcgi_params;
 		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 		fastcgi_param DOCUMENT_ROOT $document_root;
 		fastcgi_param SCRIPT_NAME $fastcgi_script_name;
 		fastcgi_param DOCUMENT_URI $uri;
 		fastcgi_param REQUEST_URI $request_uri;
 		fastcgi_pass unix:/run/uce/fastcgi.sock;
 	}
 	location ~ \.ws\.uce$ {
 		error_page 418 = @uce_websocket;
 		if ($http_upgrade = "websocket") {
 			return 418;
 		}
 		include fastcgi_params;
 		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 		fastcgi_param DOCUMENT_ROOT $document_root;
 		fastcgi_param SCRIPT_NAME $fastcgi_script_name;
 		fastcgi_param DOCUMENT_URI $uri;
 		fastcgi_param REQUEST_URI $request_uri;
 		fastcgi_pass unix:/run/uce/fastcgi.sock;
 	}
 	location @uce_websocket {
 		proxy_http_version 1.1;
 		proxy_set_header Host $host;
 		proxy_set_header X-Real-IP $remote_addr;
 		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 		proxy_set_header X-Forwarded-Proto $scheme;
 		proxy_set_header Upgrade $http_upgrade;
 		proxy_set_header Connection $connection_upgrade;
 		proxy_pass http://127.0.0.1:8080;
 	}
 }
 ```
 Important details:
 - `.ws.uce` must be matched before the more general `.uce` rule
 - `fastcgi_pass` should point at the same socket path as `FCGI_SOCKET_PATH`
 - `proxy_pass` should point at the runtime's `HTTP_PORT`
 - ordinary `GET /page.ws.uce` page renders should stay on FastCGI
 - only upgrade requests for `/page.ws.uce` should go through the HTTP/WebSocket listener
 - `SCRIPT_FILENAME` should resolve to the actual `.uce` file on disk
 - `proxy_http_version 1.1` and the `Upgrade` / `Connection` headers are required for WebSockets
 The `location /` block above is intentionally conservative and only serves real files from `site/`. If your app uses a front-controller pattern such as routing everything through `/index.uce`, change that block accordingly.
 ### 6. Think about document root and private files
 Point nginx at `site/`, not the repository root. The repo still contains source, scripts, packaging files, and operational assets that are not meant to be public.
 At minimum, explicitly block internal directories that should never be served directly. For example:
 ```nginx
 location ~ ^/(src|scripts|etc|bin|work|dist|pkg)/ {
 	return 404;
 }
 ```
 If nginx is rooted at `site/`, most of those paths will not be reachable anyway, which is the preferred setup.
 ### 7. Reload nginx and verify the deployment
 After writing the nginx config:
 ```bash
 nginx -t
 systemctl reload nginx
 ```
 Then verify:
 ```bash
 systemctl status uce.service
 curl -i http://127.0.0.1/test/index.uce
 curl -i http://127.0.0.1/doc/index.uce
 ```
 If WebSockets are enabled, also verify a `.ws.uce` endpoint through nginx rather than talking to the runtime directly.
 ### 8. Troubleshooting
 Common failure modes:
 - `502 Bad Gateway`
  Usually means `uce.service` is down, the Unix socket path does not match, or the request crashed before sending a valid response.
 - WebSocket upgrade fails
  Check that nginx is routing `.ws.uce` to `proxy_pass`, not `fastcgi_pass`, and that `HTTP_PORT` is reachable on localhost.
 - Requests compile but immediately crash
  Check `journalctl -u uce.service`. Generated units carry an ABI metadata sidecar and should be recompiled automatically after runtime ABI changes, but clearing stale artifacts under `BIN_DIRECTORY` is still a useful last-resort recovery step if the cache has been damaged manually.
 - nginx serves raw source or internal files
  Tighten the server root and add explicit deny rules for non-public directories.
 ## Repo Helpers
 - `./codesearch <pattern> [rg options...]`
 This is a small repo-root wrapper around `rg` that searches from the project root and skips generated/build directories such as `.git/`, `bin/`, `dist/`, and `work/`.
 ## Reference Notes
 For up-to-date usage, prefer:
 - the live docs under `site/doc/`
 - the declarations in `src/lib/compiler.h`, `src/lib/sys.h`, and `src/lib/functionlib.h`
 - the example pages under `site/test/`

 # WASM-PROPOSAL: WebAssembly Unit Runtime for UCE
 - **Status:** design guide; Phase 0–4 spikes complete and gated (2026-06-12).
  Next: production implementation, starting with the Phase 3 work plan
  (item 1, real `uce_lib` core compile); the starter parity bar
  (`tests/run_network_tests.py --match starter`, 14 cases) is already green
  against the native backend.
 - **Scope:** replace the native unit pipeline (generated C++ → clang → `.so` →
  `dlopen`) with per-unit WebAssembly modules executed in a per-request,
  runtime-linked workspace, exposing the same API surface to page code,
  enabling memory safety, better execution control, and paving the way for
  supporting more source languages in the future.
 ---
 ## 1. Motivation
 Two long-standing structural problems and one strategic opportunity share a
 single root cause: **request code shares an address space and an allocator
 with the runtime.**
 1. **The arena attempt failed for a structural reason.** The
   `GLOBAL_ARENA_ALLOCATOR` design in `_scratchpad.cpp` swapped the global
   `operator new`/`delete` against a `current_memory_arena`. A single global
   allocator cannot distinguish request-lifetime allocations from
   process-lifetime ones: during a request, server-lifetime structures
   (compile registry, sessions, config trees, unit statics) also allocate.
   Under the arena those dangle on reset; with `delete` as a no-op,
   system-allocated objects released mid-request leak. The lifetime
   distinction lives in the type system and call graph, not at the allocator
   boundary — fixing it in-process means threading PMR allocators through
   `String`, `DValue`, and every container.
 2. **Fault recovery is best-effort, not sound.** The current
   SIGSEGV → `sigsetjmp`/`siglongjmp` recovery performs no unwinding, skips
   destructors, can resume over corrupted worker state, and (see
   RECOMMENDATIONS.md 1.5) cannot reliably produce a useful backtrace.
   A faulting unit *can* have scribbled on runtime memory before the signal.
 3. **UCE can only ever host fully-trusted code.** A `.uce` page is arbitrary
   native code with full process privileges. Multi-tenant or user-supplied
   page hosting is structurally impossible in the native model.
 A WASM execution model deletes the shared-fate fact itself rather than
 patching around it:
 - **Arena by construction:** each request runs in its own linear memory,
  dropped wholesale at request end. Request-lifetime memory physically cannot
  outlive the request; server-lifetime state physically cannot live inside
  it. The `_scratchpad.cpp` design becomes correct because the boundary is
  structural, not typological.
 - **Sound recovery:** a trap (null deref, OOB, stack exhaustion) is a defined
  host-side error that unwinds cleanly, with a precise guest stack trace, and
  the unit cannot have touched host memory. Render error page, drop
  workspace, keep serving — actually correct, not hopeful.
 - **Capability security:** page code gets exactly the imported API surface
  and nothing else. Multi-tenant hosting becomes possible.
 - **Secondary wins:** architecture-independent unit artifacts (no clang
  required on prod), safe module unload/replace (vs. never-safe `dlclose`),
  first-class limits (linear-memory cap = RAM limit, epoch/fuel = CPU
  timeout), per-request memory stats for free.
 **Expected outcome:** ~1.2–2× compute slowdown vs. native (still far ahead of
 interpreted runtimes); a real ABI/membrane design; ownership of a custom
 loader; toolchain rough edges (§10). More isolated, shared-nothing PHP architecture
 but with a good story about websockets, generic sockets, background tasks,
 and other long running processes.
 ---
 ## 2. Rejected alternatives (recorded so they stay rejected)
 - **In-process PMR arena.** Requires re-typedefing `String`/`DValue` and
  threading allocators through the entire codebase; the failed global-swap
  shortcut is the only cheap version and it is unsound (§1.1).
 - **One instance per component.** UCE components are function calls, not
  RPCs: callees receive the context **by reference**, mutate `context.call`,
  share the `ob_*` capture stack and `ONCE` dedup state. Per-component
  instances force serialize/copy/deserialize of the context on every
  `component()` call (a dozen+ per page in the starter), require
  host-mediation of the ob stack, and silently change reference semantics to
  copy semantics. Rejected.
 - **One linked module per app ("the blob").** Introduces an "app" concept
  UCE does not have, makes every edit a global relink, turns the artifact
  cache into a build graph — webpack's worst traits without its benefits.
  Rejected. The file stays the unit.
 - **Eager pre-loading of known units at worker warm-up.** Rejected; loading
  is strictly lazy, on first explicit call, preserving current semantics.

 ## 3. Architecture overview
 ### 3.1 Execution model
 ```
 host process (linux_fastcgi, per worker)
 │
 ├─ vendored wasm runtime (§10.1)
 ├─ unit artifact cache: one PIC .wasm per unit (replaces per-unit .so)
 ├─ loader (§6): dylink parsing, base allocation, GOT resolution,
 │   symbol registry, ABI stamp check
 ├─ core snapshot: "core module, initialized" memory+table image
 │
 └─ per request: WORKSPACE
   ├─ linear memory (CoW-born from core snapshot)
   ├─ shared funcref table
   ├─ core module instance  (uce_lib + libc compiled to wasm)
   ├─ unit module instances (loaded lazily, on first call, incl. mid-request)
   └─ host handle table     (sqlite/mysql/file/socket handles + closers)
 ```
 - **Workspace = request.** Born from the core snapshot, dropped at request
  end. Memory drop is the arena; handle-table drop is resource cleanup
  (this generalizes and replaces the per-connector
  `cleanup_*_connections()` pattern — RECOMMENDATIONS.md 1.7 / 5.1 become
  structurally unrepresentable).
 - **One unit = one PIC wasm module.** Compile, cache, and invalidation
  granularity stay per-file. The `.uce → C++` translation pipeline is
  unchanged; only the compile target changes
  (`clang --target=wasm32-wasi -fPIC` + `wasm-ld -shared`).
 - **Strictly lazy loading.** A unit's module is instantiated into a
  workspace the first time that workspace calls it — including mid-request.
  This is the wasm equivalent of today's compile-and-`dlopen`-on-first-hit
  and requires no restart, no fallback path. Placement memoization
  (deterministic bases so repeat instantiation is cheaper) is a permitted
  optimization; it must not change the loading policy.
 - **In-flight isolation.** Module versions are immutable; a recompiled unit
  becomes a new module. Running workspaces keep what they loaded; new
  workspaces get the new version. Old modules are dropped when unreferenced
  (safe unload — impossible with `dlclose`).
 ### 3.2 Memory model
 - **One heap, one allocator, one DValue implementation** — all owned by the
  core module. Unit modules *import* `malloc`/`free`/runtime symbols via GOT;
  the loader **rejects any unit module that defines rather than imports
  them** (two allocators on one heap is the one fatal misconfiguration).
 - **Arena workspace allocator.** Because the workspace heap is dropped wholesale,
  the core's allocator may be a bump allocator with no-op free — the
  `_scratchpad.cpp` design, now correct by construction. Per-deployment
  flag; fallback is wasi-libc dlmalloc. Memory stats = heap pointer − base
  (replaces the tracking `operator new` in `types.h`).
 - **Unit statics reset per request** (workspace is born from the core
  snapshot, which does not include unit data; unit data segments initialize
  at unit load within the workspace). This is *more* shared-nothing than
  today, where `.so` statics persist across requests within a worker.
  Cross-request state must use explicit host facilities (sessions, caches).
  **Breaking change — must be called out in docs and checked against the
  site/ tree during Phase 5.**
 ### 3.3 The host membrane
 Exactly three currencies cross between host and workspace:
 1. **scalars** (i32/i64/f64),
 2. **byte buffers** (`ptr+len` into linear memory; inbound buffers are
   placed via the core's exported allocator), on the C++ side we strictly
   prefer the binary-safe std::string as a container for buffers
 3. **handles** (opaque `u32` indices into the per-workspace host handle
   table; each entry carries a closer callback).
 Everything pointer-shaped stays on its own side. Hostcall surface budget:
 30–60 functions (§5.1). Host errors return as error values; traps are
 reserved for unit faults. Nothing throws across the membrane.
 **DValues cross the membrane only as the versioned wire encoding** (§5.3),
 at the following sites: request context in (once), response out (once),
 some hostcalls.
 It is expected that many if not most of the toolset API functions we
 expose to the unit developer will be judiciously split across the membrane:
 have a relatively minimal wasm part that calls into the runtime host, and
 then the runtime implementation which does most of the work.
 ### 3.4 DValue inside the workspace: no serialization, ever
 Within a workspace, all modules share one address space, one toolchain, one
 set of headers — the C/C++ ABI is intact across module boundaries. Therefore:
 - A `DValue` is a pointer (an i32 offset into linear memory).
 - `component(path, context)` resolves path → table index (host registry or
  guest-resident map) and `call_indirect`s, passing the context pointer.
  Reference semantics, mutation visibility, shared ob stack, working `ONCE`
  — identical to today.
 - Function pointers are shared-table indices, valid across modules: virtual
  calls, `std::function` callbacks (`dv_map` lambdas) work across units.
 - Cost: one `call_indirect` (single-digit ns) + GOT loads for cross-module
  symbols — the same shape of overhead native PIC pays through the PLT/GOT,
  i.e. what dlopened `.so` units pay today.
 Encode/decode is **not** part of internal component calls. It exists only at
 the membrane (§3.3) and at any future explicit isolation boundary (§4).
 ### 3.5 The DValue C ABI (load-bearing, build it first)
 The stable contract of the workspace is a **C ABI**, not the C++ class:
 the core exports `extern "C"` accessors over an opaque `uce_dvalue*` (§5.2),
 plus the string/ob/print helpers. C++ units may bypass it and use the class
 directly (same headers, zero cost — a private fast path). Every other
 workspace language uses the C surface.
 This ABI is versioned: every unit artifact carries a custom section
 (`uce.abi`: core ABI version + toolchain fingerprint); the loader refuses
 stale units and triggers lazy recompilation (units are lazily compiled
 anyway, so this costs nothing structurally).
 **Phase 1 of the implementation plan is to introduce this C ABI in the
 current native runtime** — it is useful immediately (plugin surface,
 testability) and de-risks the rest.
 ---
 ## 4. Component-call model / supported languages
 The supported model is one workspace peer model: languages must be able to
 produce PIC linear-memory modules that adopt the core allocator and join the
 workspace.
 **Workspace peers** (C++, C, Rust, Zig, …):
 - Join the workspace as PIC modules importing core symbols.
 - Must adopt the core allocator (Rust: `#[global_allocator]`; Zig: allocator
  parameter) and must not unwind across boundaries (`panic=abort` /
  catch-at-edge).
 - Access DValues through the C ABI: pointer semantics, no copies, ns-scale
  calls. Idiomatic wrappers per language (e.g. Rust `DValue<'request>` —
  the borrow checker enforces the arena invariant).
 **Runtime-carrying/interpreted languages** (JS, Python, Go, C#, …) are not
 supported and are not on the roadmap. UCE will not add an alternate component
 plane that silently changes `component()` from mutable in-workspace reference
 semantics into copied RPC semantics.
 If UCE later supports isolated or cross-trust-boundary components, those must be
 introduced as an explicit feature with an explicit API name and copied data
 contract. They must not reuse normal `component(path, context)` semantics.
 Serialization boundaries and isolation boundaries remain the same lines, by
 design.
 ---
 ## 5. ABI sketches (to be finalized in Phase 0/1)
 ### 5.1 Hostcall surface (grouped; target ≤ 60 functions)
 ```
 request:   uce_host_ctx_read(buf) → len          // wire-encoded context, once
 response:  uce_host_respond(status, hdrs_buf, body_buf)
           uce_host_stream_write(buf)            // chunked/streaming path
 log:       uce_host_log(level, buf)
 sqlite:    uce_host_sqlite_connect(path_buf) → handle | err
           uce_host_sqlite_query(handle, sql_buf, params_buf) → result_buf | err
           uce_host_sqlite_cursor_*(...)         // optional row-cursor variant
           uce_host_sqlite_insert_id/affected/error/disconnect(handle)
 mysql:     (same shape; existing connector APIs are already handle-shaped)
 files:     uce_host_file_read/write/stat/list(path_buf, ...)   // policy-gated
 session:   uce_host_session_get/set(key_buf, val_buf)
 http:      uce_host_http_request(req_buf) → handle/result_buf  // outbound
 misc:      uce_host_time(), uce_host_random(buf), uce_host_env(key_buf)
 loader:    uce_host_component_resolve(path_buf) → table_index  // may load (§6)
 ws:        uce_host_ws_send(buf), event delivery via render entry re-invocation
 ```
 Conventions: all errors as result codes + `uce_host_last_error(buf)`;
 inbound buffers placed via the core's exported `uce_alloc`; no hostcall
 traps on bad input (clamp/error instead).
 ### 5.2 DValue C ABI (core exports; sketch)
 ```c
 typedef struct uce_dvalue uce_dvalue;                 // opaque; workspace-owned
 uce_dvalue*  uce_dv_root(void);                   // request context
 uce_dvalue*  uce_dv_get(uce_dvalue*, const char* key, size_t klen); // create-on-write
 uce_dvalue*  uce_dv_find(uce_dvalue*, const char* key, size_t klen); // NULL if absent
 const char* uce_dv_value(uce_dvalue*, size_t* len);
 void        uce_dv_set_value(uce_dvalue*, const char* v, size_t vlen);
 size_t      uce_dv_count(uce_dvalue*);
 int         uce_dv_is_list(uce_dvalue*);
 /* iteration */
 uce_dv_iter uce_dv_iter_begin(uce_dvalue*);
 int         uce_dv_iter_next(uce_dvalue*, uce_dv_iter*,
                                const char** key, size_t* klen, uce_dvalue** child);
 /* encode/decode at the membrane */
 size_t      uce_dv_encode(uce_dvalue*, char* buf, size_t cap);   // → UCEB1
 uce_dvalue*  uce_dv_decode(const char* buf, size_t len);
 /* ob / print / helpers: uce_print, uce_ob_start, uce_ob_get_close,
   uce_html_escape, uce_json_encode, ... (mirror uce_lib surface) */
 ```
 No unwinding across this surface; C++ exceptions are caught at the edge and
 surfaced as error returns where fallible.
 ### 5.3 Wire encoding "UCEB1" (membrane + cross-instance only)
 Length-prefixed binary tree; **not** JSON. Sketch (finalize against DValue's
 actual fields — value + ordered children):
 ```
 node  := value children
 value := varint len, bytes (utf-8)
 children := varint count, count × ( key: varint len + bytes, node )
 flags := one leading byte per node reserved (bit0: is_list hint)
 header := "UCEB" u8 version
 ```
 This encoding is a **versioned protocol** from day one (header byte). It is
 for future explicit isolation-boundary contracts and the membrane format;
 internal calls never see it.
 UCEB1 encoding/decoding should also be exposed to the unit developer so
 they can make use of fast serialization/deserialization: matching our existing
 API conventions these should be ucb_encode(DValue val) and ucb_decode(String val). This may also be
 a worthwhile target for session variables storage (either change session
 to DValue or add StringMap support to UCEB1 ser/de).
 ### 5.4 Unit module contract
 ```
 custom sections:  dylink.0 (standard), uce.abi { abi_version, toolchain_id }
 imports:          env.memory, env.__indirect_function_table,
                  env.__memory_base, env.__table_base,
                  GOT.mem.* / GOT.func.* (resolved by loader),
                  core symbols (malloc, uce_dv_*, uce_print, ...)
 exports:          uce_unit_setup, uce_unit_render,
                  uce_unit_component, uce_unit_websocket
                  (same roles as today's UCE_SETUP/RENDER/COMPONENT/WEBSOCKET
                   dlsym symbols in compiler.cpp)
 forbidden:        defining malloc/free/operator new, own memory, start fn
                  with side effects beyond data init
 ```
 ---
 ## 6. The loader (host-side, custom, load-bearing)
 Owned code, ~1–2k lines, vendored-runtime-adjacent. Reference logic:
 Emscripten's dylink loader (the ABI is the stable, battle-tested part; the
 server-side loader is what doesn't exist off the shelf).
 Per `load(unit)` into a workspace:
 1. Fetch compiled module from artifact cache (compile on miss — today's
   lazy-compile path, retargeted).
 2. Verify `uce.abi` stamp against the core; on mismatch, recompile unit.
 3. Verify import discipline (no allocator/runtime definitions; §3.2).
 4. Parse `dylink.0`: data size/alignment, table slots needed.
 5. Allocate `__memory_base` (bump within workspace data region) and
   `__table_base` (append to shared table).
 6. Instantiate with bases; resolve `GOT.*` imports against the workspace
   symbol registry (core symbols + previously loaded units); register the
   unit's exports. NB: data exports of PIC modules are `__memory_base`-relative
   offsets — add the owning unit's base when registering/resolving (core
   exports are absolute; the core is non-PIC). See the Phase 0 FINDINGS
   erratum; the Phase 3 spike's `self-got` marker exists to catch this.
 7. Register entry points in the path → table-index dispatch map.
 `uce_host_component_resolve(path)` consults the dispatch map and calls
 `load()` on miss — this is how lazy, programmatic, mid-request loading works
 with no special cases.
 Placement memoization (optional, later): record each unit's first-assigned
 bases; reuse across workspaces so instantiation is cheaper and snapshot
 growth (below) stays consistent. Does not change the lazy policy.
 **Core snapshot:** the only pre-built state is "core module, initialized" —
 memory bytes + table state captured once per core build. Workspaces are born
 from it via CoW (`mmap(MAP_PRIVATE)` of the snapshot image; the host owns
 the Memory object, so OS-level CoW is available). No units are pre-fed.
 ---
 ## 7. Request lifecycle (replaces the native flow in linux_fastcgi.cpp)
 ```
 1. accept request (fastcgi, websockets message, socket event, CLI request)
 2. workspace = birth_from_core_snapshot()          (CoW, ~µs)
 3. write wire-encoded context into workspace; core decodes → context DValue
 4. resolve entry unit (load on first call); call uce_unit_render(ctx_ptr)
 5. component(path) inside guest → resolve hostcall → (lazy load) →
   call_indirect — reference semantics throughout
 6. I/O via hostcalls; resources land in the workspace handle table
 7. on return: encode response/headers out; write FastCGI response
   on trap: defined error → render error page with guest stack trace;
   workspace state is irrelevant because…
 8. drop workspace: linear memory gone (arena), handle table closed
   (generalized resource cleanup), instances released
 ```
 CPU limit: epoch/fuel interruption → same path as trap.
 Memory limit: linear memory max → allocation failure / trap → same path.
 ---
 ## 8. What carries over unchanged
 - The `.uce → C++` translation, parser, and page semantics.
 - The lazy compile-on-first-request model and per-unit artifact caching
  (different artifact format).
 - The host-side connectors (sqlite/mysql) — already handle-shaped APIs; they
  move behind hostcalls with the same `.uce`-visible signatures.
 - The site tree, docs, demo, and the network test suite
  (`tests/run_network_tests.py`) — which becomes the parity harness (§9).
 - nginx/FastCGI front-end integration, worker model, websocket event flow
  (events re-enter via the websocket entry point).
 ---
 ## 9. Implementation plan
 Phases are sequential; each has an exit criterion. No phase except 0 and 2's
 scaffolding produces throwaway work. All dependencies must be vendored.
 **Phase 0 — toolchain & runtime.**
 Validate: wasi-sdk `-fPIC` + `wasm-ld -shared` on a representative generated
 unit; cross-module C++ calls with shared memory/table; exceptions decision
 (wasm EH vs. error-code discipline at unit boundaries — pick one, record it);
 vendored runtime selection. Candidates: **WAMR** (C, small, designed for
 embedding, easiest to vendor and patch — fits the project's vendoring
 practice and would be preferred) vs. **Wasmtime** (fastest, best AOT/CoW machinery, Rust — heavier
 to vendor/patch, use only if blocked on WAMR). Selection criteria: imported-memory + shared-table support,
 AOT artifact quality, patchability. Exit: a two-module (core stub + unit
 stub) hello-world linked at runtime by a minimal loader, in the chosen
 vendored runtime.
 > **Status: DONE (2026-06-12).** Exit criterion passed on k-uce; see
 > `spikes/wasm-phase0/FINDINGS.md`. Runtime selected: **Wasmtime v45.0.1**
 > — WAMR is blocked on the load-bearing requirement (its wasm-c-api ignores
 > imported memories/tables; host-side table growth unsupported). wasi-sdk-33
 > PIC validated on stubs **and** on real generated units
 > (`collections.uce.cpp`, `hello.uce.cpp` → side modules, no allocator
 > definitions). Exceptions: `-fno-exceptions` confirmed across all of it
 > (§11.1 stands). Cross-module C++ (containers, heap objects, function
 > pointers, `std::function` lambdas, GOT.mem/GOT.func) all proven through
 > the spike loader.
 **Phase 1 — DValue C ABI in the native runtime.**
 Introduce `uce_dv_*` (§5.2) and the UCEB1 codec in `src/lib/`, used
 natively. Zero wasm dependency; immediately testable; freezes the contract
 everything else builds on. Exit: codec round-trip + accessor tests in the
 existing suite; ABI doc checked in.
 > **Status: DONE (2026-06-12).** Native runtime now exposes `uce_dv_*`
 > accessors and UCEB1 encode/decode helpers in `src/lib/dvalue.{h,cpp}`.
 > ABI details are checked in at `docs/wasm-phase1-dvalue-abi.md`; UCE-visible
 > docs are available as `ucb_encode`/`ucb_decode`. Exit coverage is in
 > `site/tests/core.uce` and passed in the full network suite.
 ***Phase 1 Addendum***
  Fix before commit:
 1. ucb_encode(DValue value) deep-copies the whole tree (dvalue.cpp:962, same signature in the header). DValue copy is a full recursive map+string clone, and this function is the future membrane hot path — the request context will pass through it on every request in Phase 2. Should be const DValue& (the function only reads). Same nit for bool ucb_decode(String encoded, ...) at :971 — a by-value String copy of what may
 be a large document; const String& matches.
 2. 'P' values ship the raw pointer address on the wire (ucb_node_scalar, dvalue.cpp:833, the 'P' case). The ABI doc explicitly says "pointer/reference identity is intentionally not part of the wire contract," but the implementation encodes std::to_string((u64)ptr) — a meaningless number on the receiving side and an ASLR address disclosure the day UCEB1 crosses a trust boundary (multi-tenant isolation is the stated
 endgame). It's consistent with native to_string, but the wire is a different context: I'd encode "" for 'P' and note it in the doc.
 3. f64 fidelity on the wire. 'F' encodes through std::to_string → fixed 6 decimals. That's faithful to native to_string, but the membrane makes it new lossiness: today an 'F' value never round-trips through its string form unless page code asks; in Phase 2 every float in the context will. 1e-7 becomes "0.000000" → decodes to 0. Since the scalar is just a string, switching 'F' to shortest-round-trip formatting
 (%.17g-style) later needs no version bump.
 4. uce_dv_iter is about to be frozen with no headroom. Keyed-map iteration does std::advance(begin(), position) per call (dvalue.cpp:1096) — O(n²) per full sweep, and the C ABI will be the only iteration path for non-C++ units. The fix (e.g. resuming via lower_bound on the last key) needs state the one-field struct can't hold. Phase 1's whole purpose is freezing this contract: I'd add reserved space now (size_t
 position; size_t reserved[3]; or an opaque byte array) so the implementation can get smarter without an ABI break.
 Also:
  - uce_dv_decode returns a pointer into a single thread-local slot (:1122) — a second decode silently invalidates the first result. The doc documents borrowing for uce_dv_value but not this; one sentence ("valid until the next uce_dv_decode on the thread") would close it.
  - An empty non-list map round-trips as scalar "" (type 'M' → 'S'; the child_count == 0 && !LIST branch at dvalue.cpp:873ff). HOPEFULLY harmless in practice (is_array() flips), maybe worth a doc line.
  - The decoder silently drops a scalar when children are present — unreachable from the encoder, only crafted input. Fine for v1; "reserved" mention in the format doc would pin it.
  - Tests cover only the happy path. The hardening (truncation, bad magic, wrong version, depth bomb) is implemented but untested — two or three negative ucb_decode checks in core.uce would lock it in. A float/bool round-trip check would also have surfaced finding 3.
 > **Addendum status: DONE (2026-06-12).** `ucb_encode`/`ucb_decode` now take
 > const references, pointer nodes encode as empty scalars, floating-point
 > scalars use `max_digits10`, `uce_dv_iter` has reserved ABI headroom, docs
 > cover decode-root lifetime and v1 edge cases, and core tests include invalid
 > input plus float/bool round-trips.
 **Phase 2 — core module + membrane.**
 Compile `uce_lib` (+ wasi-libc) to wasm as the core module; implement the
 hostcall surface (§5.1) in the host; temporary scaffolding allowed: one
 statically-linked unit + core to validate codegen and membrane without the
 loader. Exit: one real `.uce` page (e.g. `site/tests/core.uce`) renders
 correctly through the membrane. Scaffolding is marked throwaway.
 > **Status: MEMBRANE SCAFFOLD DONE (2026-06-12).** Temporary scaffold checked
 > in under `spikes/wasm-phase2/`: a WASM reactor core subset owns memory,
 > `Request`, `DValue`, UCEB1, and output buffering; the Wasmtime host implements
 > the initial `uce_host_ctx_read`/`uce_host_log` membrane and passes a UCEB1
 > request context into the guest; a statically linked `.uce` render entry runs
 > through that membrane. Validation passed on k-uce with `PHASE2 EXIT CRITERION:
 > PASS`. The scaffold does not yet exercise UCE preprocessor-emitted page C++;
 > generator-emitted units through this membrane are explicitly deferred into the
 > Phase 3 loader path. Full dynamic unit loading also remains Phase 3 as planned.
 **Phase 3 — the loader + workspace.**
 Implement §6 in full: dylink parsing, base allocation, GOT resolution,
 ABI/import verification, lazy mid-request loading, path dispatch. Per-request
 workspace birth/drop (plain memcpy birth is fine here; CoW is Phase 4).
 Exit: the uce-starter renders end-to-end with components loading lazily;
 `tests/run_network_tests.py --match starter` passes against the wasm worker.

 > mechanics not repeated here):
 >
 > 1. **Compile the real `uce_lib` as `core.wasm`** — the last big unknown; all
 >    spikes used a hand-stubbed `Request`. Forces: `types.h` allocator gate as

 >    (`--whole-archive` vs keep-list), and splitting connectors out of the core
 >    (the MySQL client library cannot compile to wasm). Gates items 2–6.
 > 2. **WASI decision (record in §11 when made)** — spikes stub all WASI imports

 >    instead of the absolute `uce_lib.h` path; add the PIC side-module build to
 >    the compile-on-miss artifact cache.
 > 4. **Productionize the loader into `src/`** (§6): `uce.abi` stamping,

 **Phase 4 — production mechanics.**
 Core snapshot + CoW birth; bump-allocator flag; epoch/memory limits; trap →
 error-page path with guest stack traces (this supersedes the
 signal/longjmp machinery and closes RECOMMENDATIONS.md 1.5 structurally);
 handle-table cleanup (closes 1.7/5.1); artifact/ABI versioning end-to-end.
 Exit: kill-tests (deliberate out-of-bounds page, stack-exhaustion page,
 infinite-loop page, OOM page) produce clean error pages and an unharmed
 worker. (A literal null-deref page is not in the list: address 0 is valid
 wasm linear memory, so it does not trap — see §10.)
 > **Status: KILL-TEST SPIKE PASS (2026-06-12).** `spikes/wasm-phase4/`
 > validates the production mechanics that can be proven before the real wasm
 > worker exists: reusable compiled artifacts as a core-snapshot proxy, fresh
 > per-request stores as workspace birth/drop, **both** CPU-limit mechanisms
 > (fuel and epoch interruption — production default is epoch per the Phase 0
 > findings; Wasmtime reports epoch traps as `interrupt`), a store memory
 > limiter proven load-bearing (the OOM fixture grows within its own declared
 > max so only the limiter can deny it), trap capture with the exit gate
 > asserting a wasm backtrace and the expected cause per kill, handle closers
 > checked to run exactly once and while the store is alive, and — after all
 > six kills — a healthy request served by the same engine (the "unharmed
 > worker" half of the exit criterion). Kill fixtures are genuinely trapping
 > faults: unreachable, OOB access, stack exhaustion, fuel/epoch-limited
 > infinite loops, limiter-denied growth. A literal null deref is deliberately
 > absent (does not trap in wasm; risk recorded in §10). Passed on k-uce with
 > `PHASE4 EXIT CRITERION: PASS`. The trap-trace summarizer now exists as
 > `src/lib/wasm_trace.h` (collapses repeated frames, demangles symbols,
 > splits cause/detail) and is double-gated: live traps in the spike runner,
 > canned-message checks in `site/tests/core.uce` via the native suite. Not
 > yet production: OS-level CoW core snapshots, wiring trace summaries into
 > the error-page UI, the unit name-section policy for readable frames,
 > `linux_fastcgi.cpp` wiring, real connector handle cleanup, and artifact/ABI
 > versioning.
 **Phase 5 — parity & performance.**
 Full network suite green on the wasm worker; differential native-vs-wasm runs
 on the site tree; audit `site/` for cross-request-static reliance (§3.2
 breaking change); benchmark suite (template-heavy page, sqlite page,
 component-heavy starter page) with budgets: ≤2× native page latency,
 workspace birth ≤100µs, internal component call overhead within 10× native
 call cost. Exit: numbers published in this document, all tests and reviews pass.
 > **Status: HARNESS BASELINE PASS (2026-06-12).** `spikes/wasm-phase5/`
 > now automates the Phase 5 parity/performance gate shape before the production
 > wasm worker exists. On k-uce it ran the full native network suite (`83/83`),
 > the starter-focused parity subset (`14/14`), a heuristic code-focused `site/`
 > cross-request/static-state audit, and a warmed native benchmark baseline for
 > the template-heavy doc page, sqlite page, and component-heavy starter page.
 > The harness now gates case counts (`network >= 80`, `starter >= 10`) so broken
 > filters cannot pass vacuously, and it runs a throwaway warmup suite before the
 > measured gate to absorb cold unit-cache timeouts. Informational native medians
 > from the 2026-06-12 baseline are: template-heavy doc `313.8 ms`, sqlite page
 > `3.4 ms`, starter dashboard `41.1 ms`. A durable snapshot lives in
 > `spikes/wasm-phase5/reports/native-baseline-2026-06-12.md`; paired wasm/native
 > gate runs still recompute the native medians for the actual ≤2× comparison.
 > True Phase 5 completion still requires passing the same harness against a real
 > wasm worker URL and adding worker-internal probes for workspace birth and
 > component-call overhead budgets.
 **Phase 6 — removed / not planned.**
 There is no planned second component plane for interpreted or runtime-carrying
 languages. Future work after Phase 5 should continue productionizing the single
 workspace-peer WASM backend unless Udo explicitly approves a separate isolated
 component feature with a new API name and copied-data semantics.
 The native `.so` backend remains in-tree (as a reference) and selectable by config
 but we switch over to the wasm backend as soon as it's available and test
 only on that; both backends share the Phase 1 C ABI.

 ## 10. Risks & mitigations
 | Risk | Mitigation |
 |---|---|
 | wasi-sdk PIC / shared-library maturity (least-trodden toolchain path) | Phase 0 spike before any commitment; pin toolchain versions; statically link libc into the core and export from there (avoid shared wasi-libc entirely) |
 | C++ exceptions × PIC × wasm EH | Phase 0 decision point; fallback is error-code discipline at unit entry points (units already have a uniform entry shape) |
 | Custom loader correctness (GOT, bases, relocation) | Small, contained (~1–2k lines); crib logic from Emscripten's reference loader; fuzz with adversarial modules; loader rejects > loader guesses |
 | Vendored runtime patches drift from upstream | Same practice as vendored SQLite: provenance + patch files under `docs/patches/`; pin upstream tag; tests gate upgrades |
 | Performance regression beyond budget | Phase 5 gates; bump allocator and placement memoization in reserve; native backend retained |
 | Multi-module DWARF / debugging story | Trap stack traces cover the production case (better than today); accept weaker interactive debugging; keep native backend for local deep-debugging |
 | Unit-statics semantic change breaks existing pages | Phase 5 audit of `site/`; documented migration note; host-side cache facility if a real need surfaces |
 | Null-pointer dereferences do not trap (wasm address 0 is valid linear memory) — a buggy page writes low workspace memory and renders silently wrong output instead of erroring | Accepted: damage is confined to the request's workspace and dropped at request end (strictly better than native SIGSEGV). Kill-tests use genuinely trapping faults (OOB, stack exhaustion, `__builtin_trap`). Optional later: null-check instrumentation at a measured perf cost |
 ## 11. Decisions
 1. **Exceptions:** wasm EH or error codes at unit boundaries? Error codes.
 2. **WebSocket granularity:** workspace per event (pure arena, statics reset
   per event) or per connection (state across events, bounded lifetime)?
   Per-event. Should be compatible with WS since the WS contract is: runtime holds
   and brokers connections, makes request to unit's WS() {...} directive, unit
   may decide to send data back over WS to any or even all connected clients.
 3. **UCEB1 final layout** vs. DValue's actual field set (value/children/list
   flag) — somewhat open, finalize in Phase 1.
 4. **Cursor vs. bulk** as the default for `sqlite_query` results at the
   membrane (offer both; pick the default after Phase 5 benchmarks, tending towards cursor right now).
 5. **Streaming output:** today's ob model buffers; does the membrane expose
   `uce_host_stream_write` from day one or post-MVP? Undecided. ob is a critical
   abstraction to our whole execution model and whether we expose direct stream
   write or not, the existing PHP-like ob contract/paradigm must stay in place.
 6. **Core snapshot rebuild cadence** once placement memoization lands
   (dead-base reclamation policy).
 ## 12. Summary
 The module is the **unit** (file-grained, lazily compiled, lazily loaded —
 including mid-request). The instance set is the **workspace** (one per
 request; shared memory + table; born from a core-only CoW snapshot; dropped
 wholesale — the arena, done right). The contract is the **DValue C ABI**
 inside the workspace (pointer semantics, no serialization) and the **UCEB1
 wire encoding + handles** at every true address-space boundary (host
 membrane and future explicit trust boundaries). Serialization
 boundaries and isolation boundaries are the same lines; component calls stay
 function calls; and the file stays the unit.

 # React Developer Affordances Todo
 ## Objective
 Add practical value for developers coming from React frameworks while preserving UCE's server-first C++ model. Defer component syntax/children work, avoid global head/assets/islands in the runtime, and focus on function-library data helpers, diagnostics, docs, examples, demos, and a starter-local router with starter-local asset/island components.
 ## Success Criteria
 - [x] Function library has useful collection/data-shaping helpers with docs and tests.
 - [x] Compile/runtime diagnostics are more helpful, especially for generated-code and common preprocessor mistakes.
 - [x] Docs include a concise React/Next/Remix orientation guide.
 - [x] Starter example uses a centralized hierarchical/file-based router in `index.uce` efficiently.
 - [x] Starter-local asset/island affordances live as component handlers in the starter, not global runtime APIs.
 - [x] Network tests and relevant build checks pass on `k-uce`.
 ## Current State
 - Status: complete
 - Last updated: 2026-05-28
 - Source of truth: `/root/mount_ssh/k-uce-root-htdocs-uce`
 - Runtime/live target: `k-uce:/Code/uce.openfu.com/uce`; rebuilt and restarted `uce.service` on `k-uce`.
 ## Goal Tree
 Legend: `[ ]` not started, `[~]` in progress, `[x]` done, `[!]` blocked, `[-]` superseded
 - [x] G1: Add collection/data helpers to function library
  - Why: React-framework developers routinely shape arrays/objects near render code.
  - Done when: helpers are declared, implemented, documented, and covered by tests.
  - Verify: build plus focused site/network tests.
  - [x] G1.1: Identify current `StringList`/`DValue` idioms and choose helper surface.
  - [x] G1.2: Implement minimal high-value helpers without broad template complexity.
  - [x] G1.3: Add docs and examples for helpers.
  - [x] G1.4: Add/extend tests.
 - [x] G2: Improve developer diagnostics
  - Why: React frameworks win by making failures easy to act on.
  - Done when: compile/runtime error output includes actionable context and docs mention debugging flow.
  - Verify: intentional broken page surfaces improved message.
  - [x] G2.1: Inspect current compiler/runtime error rendering path.
  - [x] G2.2: Add source excerpt / generated path / common-hint text where appropriate.
  - [x] G2.3: Document diagnostics.
 - [x] G3: Add React/Next/Remix orientation docs
  - Why: mapping familiar concepts reduces onboarding cost without adding syntax.
  - Done when: docs page exists and is linked from docs/README/demo surfaces.
  - Verify: docs page renders live.
 - [x] G4: Starter-local router and starter affordances
  - Why: User specifically wants hierarchical/file-based routing beautifully in starter `index.uce`.
  - Done when: starter routes go through a central router in `index.uce`, and starter-local asset/island component handlers exist and are used where sensible.
  - Verify: key starter routes render 200.
  - [x] G4.1: Inspect current starter routing.
  - [x] G4.2: Refactor to clear route table / hierarchical file resolution in `index.uce`.
  - [x] G4.3: Add starter-local `COMPONENT:asset` / `COMPONENT:island` style handlers in one unit.
  - [x] G4.4: Use them efficiently in starter pages/layout.
 - [x] G5: Demos and examples
  - Why: Affordances must be visible to developers, not hidden in APIs.
  - Done when: docs/demo/tests expose examples.
  - Verify: demo URLs return 200 and tests pass.
 - [x] G6: Verification and project docs
  - Done when: build/test commands are run on `k-uce`, project notes updated, and adversarial review completed.
 ## Execution Queue
 Complete.
 ## Decisions
 - 2026-05-28: Defer component children/slots and JSX-like preprocessor syntax.
 - 2026-05-28: Do not add global runtime head/assets/islands APIs; implement asset/island as starter-local components.
 - 2026-05-28: Do not add a generic runtime file-based-routing system; demonstrate hierarchical/file routing inside starter `index.uce`.
 - 2026-05-28: Keep collection helpers explicit (`list_*`, `dv_*`) instead of overloading generic names such as `map`/`sort`.
 ## Assumptions
 - Current source-of-truth mount is live-editable; runtime validation requires SSH to `k-uce`.
 - Existing site tests are the right place for function-library coverage.
 ## Blockers and Risks
 - No current blockers.
 - Future risk: if UCE grows a full parser or component-tag syntax, keep this pass's explicit component/router APIs as a stable lower-level fallback.
 ## Evidence and Verification Log
 - 2026-05-28: Created plan after reviewing README, preprocessor docs, and function library headers.
 - 2026-05-28: `ssh k-uce 'cd /Code/uce.openfu.com/uce && bash scripts/build_linux.sh'` succeeded.
 - 2026-05-28: Restarted `uce.service` on `k-uce`.
 - 2026-05-28: `tests/run_network_tests.py --match core` passed.
 - 2026-05-28: Manual checks returned `200` for `/examples/uce-starter/index.uce`, `?dashboard`, `?workspace/projects`, `?themes`, `/demo/collections.uce`, `/doc/index.uce?p=coming_from_react`, `/doc/index.uce?p=list_map`, and `/doc/index.uce?p=dv_group_by`.
 - 2026-05-28: Full internal network suite passed, 25/25.
 - 2026-05-28: Temporary broken `/tests/diagnostic-probe.uce` returned `500` with formatted `UCE compile error` diagnostics; source and cache artifacts were removed afterward.
 ## Change Log
 - 2026-05-28: Created initial goal tree.
 - 2026-05-28: Implemented helpers, diagnostics, docs, demo, starter router, starter-local web affordance components, tests, and validation.
 ## Follow-up Cleanup 2026-05-29
 - Removed duplicate route cleanup from `starter_router_candidates()` because `app_make_route()` is the single normalization point for `l_path`.
 - Weeded out nearby duplicate/obsolete starter code:
  - `starter_router_add_candidate(...)` now owns repeated candidate tree construction.
  - Removed unused `app_resolve_view()` / `starter_resolve_view()` after moving routing into starter `index.uce`.
  - Removed unused legacy registered asset rendering functions from `lib/app.uce`; registered assets now render through `components/theme/web_affordances.uce`.
  - `app_init()` now reuses `app_base_url(context)` instead of repeating base URL derivation.
  - `web_affordances.uce` now uses one `starter_render_asset_group(...)` loop for CSS and JS.
 - Verification: rebuilt on `k-uce`, restarted `uce.service`, checked key starter routes, and ran `tests/run_network_tests.py --match core` successfully.
 ## Follow-up Routed Views 2026-05-29
 - Changed starter route dispatch from `unit_render(...)` to `component(...)`.
 - Converted all routed `site/examples/uce-starter/views/*.uce` files to `COMPONENT(Request& context)` rather than `RENDER(Request& context)` because they are central-router-only views.
 - Updated the starter README and verified key starter routes. No service restart was required because only `.uce`/docs changed.
 ## Follow-up Canonical Starter URLs 2026-05-29
 - Canonicalized starter self-links from `/examples/uce-starter/index.uce?...` to `/examples/uce-starter/?...` with `app_canonical_script_url(...)`.
 - Updated the starter README to show canonical directory URLs.
 - Touched the starter front controller to force the `#load`ed helper change into the cached generated unit.
 - Verified canonical/direct starter routes and checked generated self-links. No service restart was required.
 ## Follow-up Not Found Component 2026-05-29
 - Moved `starter_router_render_not_found` markup into `components/basic/notfound.uce`.
 - Router now delegates 404 body rendering through `component("components/basic/notfound", props, context)`.
 - Verified missing routes return `404` and normal dashboard route returns `200`. No service restart required.
 ## Follow-up Page Shell Component 2026-05-29
 - Moved app page rendering into `themes/page.uce` as a component.
 - Removed `app_render_page`, `app_theme_page_component`, and `starter_render_page` from `lib/app.uce`.
 - Page template resolution now follows `context.call["app"]["page_type"]`: current theme first, common fallback second.
 - Verified representative HTML routes and the JSON page-type fallback. No service restart required.
 ## Follow-up Deep Starter Context Cleanup 2026-05-29
 - Removed repeated `starter_boot(context)` calls; root `index.uce` is the boot point.
 - Removed `context.call["starter"]` duplicated state and JSON side-channel state.
 - JSON routes now use only `context.call["app"]["page_type"]` plus normal captured output.
 - Simplified `themes/page.uce` and `themes/common/page.json.uce` accordingly.
 - Replaced `starter_*` alias helper usage with direct `app_*` helpers and removed alias wrappers except `StarterUser`.
 - Verified key routes and core tests. No service restart required.
 ## Follow-up Route Context Flattening 2026-05-29
 - Flattened `context.call["app"]["route"]` to `context.call["route"]`.
 - Moved former `context.call["app"]["router"]` metadata into `context.call["route"]`.
 - Verified representative starter HTML, 404, and JSON routes. No service restart required.

 # WASM Phase 1: DValue C ABI and UCEB1
 Phase 1 freezes the native DValue ABI that the future WASM core and units use
 as their shared structured-value contract. The implementation is in
 `src/lib/dvalue.{h,cpp}` and is available in the native runtime before any WASM
 backend is enabled.
 ## Opaque handle
 ```c
 typedef struct DValue uce_dvalue;
 ```
 `uce_dvalue*` is a borrowed pointer owned by the active request/workspace. It
 must not be freed by ABI callers and it must not be retained beyond that
 workspace lifetime.
 ## Accessors
 ```c
 uce_dvalue* uce_dv_root(void);
 uce_dvalue* uce_dv_get(uce_dvalue* value, const char* key, size_t key_len);
 uce_dvalue* uce_dv_find(uce_dvalue* value, const char* key, size_t key_len);
 const char* uce_dv_value(uce_dvalue* value, size_t* len_out);
 void uce_dv_set_value(uce_dvalue* value, const char* bytes, size_t len);
 size_t uce_dv_count(uce_dvalue* value);
 int uce_dv_is_list(uce_dvalue* value);
 ```
 - `uce_dv_root()` returns the current native request's `context.call` root.
  The WASM core will later map this to the decoded request context root.
 - `uce_dv_get()` creates the child if absent. `uce_dv_find()` returns `NULL`
  if absent.
 - String inputs and outputs are length-delimited and binary-safe.
 - `uce_dv_value()` returns a borrowed pointer valid until the next ABI value
  call on the same thread.
 - Bad `NULL` inputs return `NULL`, zero, or no-op rather than trapping.
 ## Iteration
 ```c
 typedef struct uce_dv_iter { size_t position; size_t reserved[3]; } uce_dv_iter;
 uce_dv_iter uce_dv_iter_begin(uce_dvalue* value);
 int uce_dv_iter_next(uce_dvalue* value, uce_dv_iter* iter,
                     const char** key_out, size_t* key_len_out,
                     uce_dvalue** child_out);
 ```
 Map iteration follows DValue's native order. List-shaped maps iterate in numeric
 index order (`0`, `1`, ...), matching `DValue::each()`, `dv_values()`, and the
 serializers. The reserved iterator fields are caller-opaque and must be
 zero-preserved by callers that copy the iterator; they provide ABI headroom for
 future non-linear keyed-map iteration without changing the struct size.
 ## UCEB1 wire format
 UCEB1 is the membrane/cross-instance binary DValue encoding.
 ```
 document := "UCEB" version node
 version  := 0x01
 node     := flags scalar children
 flags    := u8 bitset; bit0 = list-shaped map
 scalar   := varuint length, bytes
 children := varuint count, count * (key, node)
 key      := varuint length, bytes
 ```
 Varuint is unsigned LEB128. Strings are byte sequences; the codec does not
 assume NUL termination and preserves embedded NUL bytes. The Phase 1 layout stores scalar values as their native string representation
 plus child nodes and the list-shape flag. Floating-point values use
 `max_digits10` precision so numeric scalars can round-trip through the string
 form. Pointer/reference identity is intentionally not part of the wire contract;
 pointer nodes encode as an empty scalar rather than leaking process addresses.
 An empty non-list map has no wire distinction from an empty scalar in UCEB1 v1.
 Documents that contain both scalar bytes and child nodes are reserved for future
 use; the v1 decoder accepts the children and ignores the scalar.
 ## Codec APIs
 C++/UCE-visible helpers:
 ```cpp
 String ucb_encode(const DValue& value);
 DValue ucb_decode(const String& encoded);
 bool ucb_decode(const String& encoded, DValue& out, String* error_out = 0);
 ```
 C ABI helpers:
 ```c
 size_t uce_dv_encode(uce_dvalue* value, char* buf, size_t cap);
 uce_dvalue* uce_dv_decode(const char* buf, size_t len);
 const char* uce_dv_last_error(void);
 ```
 `uce_dv_encode()` returns the required byte length even when `buf` is `NULL` or
 `cap` is zero. `uce_dv_decode()` returns a thread-local decoded root, or `NULL`
 with `uce_dv_last_error()` populated. The returned decoded root is valid until
 the next `uce_dv_decode()` call on the same thread. Decoding rejects documents
 deeper than 1024 nested nodes so malformed input cannot recurse without bound.
 ## Test coverage
 `site/tests/core.uce` covers:
 - UCEB1 round-trip for maps, nested values, lists, empty lists, and embedded NUL
  scalar bytes.
 - C ABI get/find/value/count/list/iteration/encode/decode behavior.
