Prove the definedness property at the configured minimum. +2. If that is not proved, prove it at the configured maximum. +3.

A reachable defined-and-opposite output +is reported as `Different`. + +Startup behavior before the selected age is intentionally outside this +steady-state property. The age monitor makes that boundary explicit in the +product FSM instead of confusing it with a PDR frame number. + +## Uncertified Fallback + +If a single output is not certified as defined by the maximum age, SEC retains +the existing two checks, both gated at the maximum age: + +1.

Strict rail equality checks whether the two three-valued rail pairs differ. + +A guarded binary mismatch is a concrete counterexample. Otherwise, the output +remains `Inconclusive`, even if strict `X == X` rail equality is proved, because +definedness was not certified. The result names every affected public output +and explains that unknown data propagated from uninitialized sequential logic. + +## Disabled Flow + +With automatic age discovery disabled, the monitor and all age probes are +absent. SEC runs the existing behavior unchanged: + +1. Run guarded dual-rail PDR from the original `F[0]` with the requested + `max_k`. +2. Run the existing strict rail-equality pass for guarded-proved batches. +3. Use the existing batching, output coverage, diagnostics, and verdict rules. + +No age gating or effective frame-budget adjustment occurs on this path. + +## Reused Work + +Age probes share only property-independent model work: + +- The exact `F[0]` formula. +- The incremental `F[0]`-intersection SAT solver. +- The incremental `F[0] -> T -> cube` predecessor SAT solver. +- The frame-zero bad-state solver infrastructure. +- Transition expressions, lazy transition support, and Tseitin clauses already + stored in those shared solvers. +- Prebuilt output-definedness expressions and age-comparison expressions. + +The following are deliberately not shared because they depend on the property +or on a specific PDR run: + +- PDR frames and learned frame clauses. +- Proof obligations and predecessor results from higher frames. +- Convergence results. +- Counterexamples or `UNKNOWN` verdicts. + +This cache boundary affects performance only.

Unlike +`verify()`, it does not translate the configuration into high-level Python +options, so the native configuration parser is authoritative. + +The lower-level `run_cli()` accepts the same argument sequence as the native +executable, excluding `argv[0]`: + +```python +from kepler_formal import run_cli + +result = run_cli(("-verilog", "reference.v", "implementation.v")) +``` + +`run_cli()` is still an in-process call; “CLI” describes only its argument +shape.

For an `ERROR`, inspect `reason`, the native log output, and +`exit_code`; some early failures can provide only a general reason. + +Python argument validation still raises `TypeError` or `ValueError`. A native +safety violation (for example, an active external Naja universe) or an +unexpected native exception raises `RuntimeError` because no normal result can +be produced. + +Do not infer equivalence from `exit_code == 0`. The value preserves the native +program's historical exit convention, and LEC uses zero for both equivalent +and different designs. SEC currently uses zero for a proof, one for a partial +proof, two for inconclusive/unsupported, and three for a counterexample, but +`status` is the stable, mode-independent interpretation. + +## Result fields + +`VerificationResult` is a frozen, value-only dataclass: + +| Field or property | Meaning | +| --- | --- | +| `status` | A `VerificationStatus` semantic outcome | +| `exit_code` | The native return code; do not use it alone as the verdict | +| `input_format` | Parsed input-format string, or `None` if parsing ended before it was available | +| `verification` | Parsed `lec` or `sec` mode, or `None` if unavailable | +| `log_file` | The actual log path selected by the engine, or `None` if no log was created | +| `bound` | The SEC bound associated with the result; zero for LEC or when unavailable | +| `reason` | Engine detail or an operational error explanation, when available | +| `covered_outputs` | Outputs included in the extracted SEC comparison | +| `total_outputs` | Existing observed outputs considered during SEC extraction | +| `proven_outputs` | Outputs reported proved by the SEC engine | +| `unproven_outputs` | Names of not-yet-proved outputs when the engine reports per-output proof progress | +| `skipped_observed_outputs` | Observed-output names excluded because of extraction or coverage limitations | +| `equivalent` | `True` only when `status is EQUIVALENT` | +| `conclusive` | `True` only for `EQUIVALENT` or `DIFFERENT` | +| `coverage_percent` | `100 * covered_outputs / total_outputs`, or `None` when `total_outputs` is zero | + +The output counters are primarily meaningful for SEC. LEC and early failures +normally leave them at zero and the name tuples empty. + +### Extraction coverage is not proof progress + +`covered_outputs / total_outputs` measures whether observed outputs survived +extraction and were included in the SEC problem. Consequently, +`coverage_percent` is **not** “percent proved.” An output can be covered but +remain unproved. + +`proven_outputs` and `unproven_outputs` describe proof progress. Some engine +paths report only an aggregate count; for equivalent or partial results the +binding then uses `covered_outputs` as the best available proved count. The +engine may not provide corresponding names, so an empty `unproven_outputs` +tuple does not by itself mean that every output was proved. Check `status` +first. `skipped_observed_outputs` belongs to extraction coverage, not to the +set of covered-but-unproved outputs. + +## Lifetime, global state, and concurrency + +Results contain only Python strings, integers, tuples, and enums. They remain +valid after the call because the native Naja universe, miter state, expression +caches, and run-owned objects are released before control returns to Python. +The binding restores the Kepler solver/report settings and spdlog logger +references that it changes. + +Kepler and Naja still use process-global design, solver, and logging state. The +binding therefore has these constraints: + +- Verification calls are synchronous, serialized by a process-wide mutex, and + not reentrant. +- The binding intentionally keeps Python's GIL for the entire native run. + Other Python threads cannot execute Python code until verification returns. +- The API does not currently provide an in-process timeout or cancellation + hook. A caller that needs hard cancellation or crash isolation should place + the Python call in a separately managed process. +- A call is rejected with `RuntimeError` if another live Naja universe exists. + In particular, do not invoke verification while a NajaEDA session owns live + netlist objects. +- No `Design` or result field accepts or returns live Naja/SNL/NajaEDA objects. + Pass files or snapshots and keep only the owning result values. +- Kepler temporarily installs a process-global spdlog default/named logger and + restores the previous loggers after the run. The mutex protects Kepler calls, + but it cannot protect unrelated native threads. A host with C++ threads that + concurrently use spdlog's global default logger must coordinate those + threads or run verification in an isolated process. + +## Python technology files + +`py_tech_files` are not supported by the in-process Python package. The native +package driver deliberately excludes Naja's CPython technology loader to avoid +mixing incompatible Python runtimes and live Naja object ownership.

Calls run directly +in the current process: this package is not a subprocess wrapper and does not +use MCP or another service. + +The initial API is file-based. It is intended for running verification and +returning owning result values, not for editing live NajaEDA netlists. + +Quick start +----------- + +.. code-block:: python + + from kepler_formal import ( + Design, + InputFormat, + SecEngine, + VerificationMode, + VerificationOptions, + VerificationStatus, + verify, + ) + + result = verify( + Design("reference.v", top="top"), + Design("implementation.v", top="top"), + options=VerificationOptions( + input_format=InputFormat.VERILOG, + mode=VerificationMode.SEC, + libraries=("cells.lib",), + sec_engine=SecEngine.PDR, + max_k=32, + ), + ) + + if result.status is VerificationStatus.EQUIVALENT: + print("proved equivalent") + else: + print(result.status.value, result.reason) + +``Design.files`` accepts one path or a sequence. Each design needs one or more +files, a permitted SystemVerilog flist, or both: + +* ``verilog`` accepts files and an optional top on both sides, but no flists. +* ``systemverilog`` accepts files and/or a flist plus an optional top on both + sides. It requires SEC. +* ``sv2v`` accepts SystemVerilog files and/or a flist for design 1 and Verilog + files without a flist for design 2. It requires SEC. +* ``naja_if`` requires exactly one snapshot per side and accepts neither flists + nor top-module selections. + +Options and results +------------------- + +``VerificationOptions`` selects ``InputFormat``, ``VerificationMode``, +``Solver``, ``SecEngine``, and ``SecEncoding`` and provides Liberty libraries, +the SEC bound, top-level verification flags, and logging settings. Enum fields +also accept their exact string values. SEC engine, encoding, and bound options +cannot be used with LEC. + +The result status is one of ``NO_RESULT``, ``EQUIVALENT``, ``DIFFERENT``, +``PARTIALLY_PROVED``, ``INCONCLUSIVE``, ``UNSUPPORTED``, or ``ERROR``. Use +``result.status`` for the verdict: the historical native ``exit_code`` is not +mode-independent, and LEC returns zero for both equivalent and different +designs. Non-equivalence, partial proof, inconclusive, unsupported, no-result, +and ordinary operational-error outcomes are returned as values. Invalid +Python arguments raise ``TypeError`` or ``ValueError``; native safety failures +and unexpected native exceptions raise ``RuntimeError``. + +``VerificationResult`` also contains the parsed format/mode, actual log path, +SEC bound, reason, extraction counters, proof counters, and output-name tuples. +The result is frozen and remains valid after native run state is released. + +``coverage_percent`` is ``100 * covered_outputs / total_outputs``. It measures +observed-output extraction coverage, not proof progress. ``proven_outputs`` and +``unproven_outputs`` describe proof progress when the engine reports it; +per-output names are not available on every engine path. Always check +``status`` rather than interpreting an empty ``unproven_outputs`` tuple as a +complete proof. ``skipped_observed_outputs`` identifies outputs excluded by +extraction or coverage limitations. + +Existing configuration and CLI-shaped arguments +------------------------------------------------ + +An existing YAML or JSON configuration can be run directly: + +.. code-block:: python + + from kepler_formal import run_config + + result = run_config("verify.yml") + +The lower-level ``run_cli(arguments)`` accepts the native executable's argument +sequence without ``argv[0]``. Both functions still invoke the engine in process; +neither launches the executable. + +Process constraints +------------------- + +Kepler and Naja use process-global native state. Verification calls are +synchronous, serialized, non-reentrant, and hold Python's GIL until the run +finishes. A call raises ``RuntimeError`` if another live Naja universe exists, +including one owned by a NajaEDA session. The API does not accept or return live +Naja/SNL/NajaEDA objects. There is no in-process timeout or cancellation hook; +callers that require hard cancellation or crash isolation should manage the +Python invocation in a separate process. + +Run state and logger references are restored after each call, but Kepler +temporarily replaces spdlog's process-global default logger. Unrelated native +threads using that global logger must be coordinated, or verification should be +run in an isolated process. + +Python technology files (``py_tech_files``) are not supported by this +in-process package. A configuration containing them returns ``ERROR`` with a +nonzero exit code and an explanatory reason. Liberty libraries are supported. + +See ``docs/python-api.md`` in the source tree for the complete input rules, +option table, result-field semantics, and lifecycle notes. diff --git

Cycles with an unknown output remain outside that property. +- Startup and reset timing follow KF's concrete bounded-counterexample + semantics. The effective `sec_reset` bootstrap is encoded; as in KF's + counterexample checker, a complete binary initial-state assignment can + bypass a configured reset prefix. +- The file describes the prepared transition-system obligation, rather than + an engine's SAT clauses or learned proof state. The selected `max_k` is a KF + search bound; it does not bound the exported transition system. +- Skipped outputs remain excluded. Export coverage is reported, so a dump + with partial coverage must not be treated as a full-design equivalence + obligation. + +Successful `dump_only` exits with code `0` and reports **exported; proof not +run**, together with the file path and output coverage.

- Version 3, 29 June 2007 - - Copyright (C) 2007 Free Software Foundation, Inc. - 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. - - - Copyright (C) - - This program is free software: you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation, either version 3 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program. If not, see . - -Also add information on how to contact you by electronic and paper mail. - - If the program does terminal interaction, make it output a short -notice like this when it starts in an interactive mode: - - Copyright (C) - This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, your program's commands -might be different; for a GUI interface, you would use an "about box". - - You should also get your employer (if you work as a programmer) or school, -if any, to sign a "copyright disclaimer" for the program, if necessary. -For more information on this, and how to apply and follow the GNU GPL, see -. - - The GNU General Public License does not permit incorporating your program -into proprietary programs. If your program is a subroutine library, you -may consider it more useful to permit linking proprietary applications with -the library. If this is what you want to do, use the GNU Lesser General -Public License instead of this License.

b3acbe6724ee5fe3583826723bb8d0ee9197cba0 Mon Sep 17 00:00:00 2001 From: Noam Cohen Date: Sat, 19 Sep 2026 18:45:21 +0200 Subject: [PATCH 150/165] Add explicit paired instance boundaries Expose selected instance inputs as compared outputs and outputs as shared inputs in CLI, YAML, and Python LEC/SEC flows, including compact extraction. Add interface/connectivity validation and regression coverage while keeping normal equivalence statuses. Known limitation: a nested cut that empties its parent wrapper can cause SEC to treat that wrapper as opaque; this remains unresolved. --- docs/flags-spec.md | 39 ++ docs/python-api.md | 47 +- docs/python-primitives.md | 9 + docs/sec-flags-spec.md | 32 +- src/bin/BUILD.bazel | 1 + src/bin/CMakeLists.txt | 1 + src/bin/KeplerFormal.cpp | 243 ++++++- src/python/CMakeLists.txt | 5 +- src/python/KeplerBorrowedDesigns.cpp | 80 ++- src/python/KeplerBorrowedDesigns.h | 13 +- src/python/PyKeplerFormal.cpp | 76 ++- src/python/README.rst | 23 +- src/python/kepler_formal/api.py | 36 +- src/utils/BUILD.bazel | 10 +- src/utils/CMakeLists.txt | 3 +- src/utils/DesignBoundary.cpp | 633 ++++++++++++++++++ src/utils/DesignBoundary.h | 65 ++ test/python/borrowed_native_tests.cpp | 135 ++++ test/python/test_api.py | 30 + test/python/test_interoperability.py | 109 +++ test/python/test_native.py | 26 + test/sec/BUILD.bazel | 14 + test/sec/BoundaryEquivalenceTests.cpp | 334 +++++++++ test/sec/CMakeLists.txt | 5 + .../strategies/miter/KeplerFormalCliTests.cpp | 393 +++++++++++ test/utils/BUILD.bazel | 10 + test/utils/CMakeLists.txt | 8 + test/utils/DesignBoundaryTests.cpp | 466 +++++++++++++ 28 files changed, 2760 insertions(+), 86 deletions(-) create mode 100644 src/utils/DesignBoundary.cpp create mode 100644 src/utils/DesignBoundary.h create mode 100644 test/sec/BoundaryEquivalenceTests.cpp create mode 100644 test/utils/DesignBoundaryTests.cpp diff --git a/docs/flags-spec.md b/docs/flags-spec.md index 47a4e202..43768452 100644 --- a/docs/flags-spec.md +++ b/docs/flags-spec.md @@ -34,6 +34,7 @@ LEC is the default.

Sun, 20 Sep 2026 13:48:20 +0200 Subject: [PATCH 156/165] Add optional certified internal relation learning for SEC Enable relation learning and internal X equality by default through CLI, YAML, and Python options. Prove candidates from initialization and joint induction before publishing state equalities. Preserve the existing output property and bypass learning entirely when disabled. Add dedicated soundness and option coverage. Keep existing test assertions unchanged, disabling learning only in tests of the previous no-mining path. --- docs/btor2-export.md | 3 +- docs/flags-spec.md | 4 + docs/python-api.md | 5 +- docs/sec-flags-spec.md | 29 ++ src/bin/KeplerFormal.cpp | 78 ++++- src/python/KeplerBorrowedDesigns.cpp | 1 + src/python/KeplerBorrowedDesigns.h | 1 + src/python/PyKeplerFormal.cpp | 13 +- src/python/kepler_formal/api.py | 12 + src/sec/BUILD.bazel | 2 + src/sec/CMakeLists.txt | 1 + src/sec/kinduction/KInductionProblem.h | 7 +- src/sec/proof/InternalRelations.cpp | 203 +++++++++++++ src/sec/proof/InternalRelations.h | 39 +++ .../SequentialEquivalenceStrategy.cpp | 8 +- .../strategy/SequentialEquivalenceStrategy.h | 5 + test/python/test_api.py | 26 ++ test/sec/BUILD.bazel | 1 + test/sec/CMakeLists.txt | 1 + test/sec/InternalRelationsTests.cpp | 272 ++++++++++++++++++ .../SequentialEquivalenceStrategyTests.cpp | 2 + .../strategies/miter/KeplerFormalCliTests.cpp | 43 +++ 22 files changed, 743 insertions(+), 13 deletions(-) create mode 100644 src/sec/proof/InternalRelations.cpp create mode 100644 src/sec/proof/InternalRelations.h create mode 100644 test/sec/InternalRelationsTests.cpp diff --git a/docs/btor2-export.md b/docs/btor2-export.md index fcf3c1bb..d795ab77 100644 --- a/docs/btor2-export.md +++ b/docs/btor2-export.md @@ -66,7 +66,8 @@ SEC loading, including the identical-input model reuse path. counterexample checker, a complete binary initial-state assignment can bypass a configured reset prefix. - The file describes the prepared transition-system obligation, rather than - an engine's SAT clauses or learned proof state.

On the issue #250 designs every candidate relation therefore went uncertified (64 candidates, 0 proved on acc8; 85 candidates, 0 proved on tinyalu) and the learner had no effect on the proof. Apply the equality hypotheses by aliasing each candidate's right-hand register to its left-hand literal in the current frame, and add the remaining (definedness) hypotheses as unit clauses. Refinement re-encodes in a fresh solver instead of retracting assumptions. The certified set is unchanged in meaning; only the encoding of the same induction query differs. Dual-rail PDR self-compare, previously partial, now proves every output: acc8 7/8 -> 8/8 (~25 s -> <1 s); tinyalu 8/17 -> 17/17 (~121 s -> <1 s); accumulator banks of every size in the issue's table prove in <1 s. Add CLI regression tests for both issue #250 designs, gated on full coverage as the report recommends. Fixes #250.

It did fire for pull requests, but each table landed in a detached run labelled main that the pull request never links to, so in practice only main had a usable summary. Make the summary the last job of regress-sec instead. It now belongs to the run it reports on, so every pull request shows it in its checks, on its own run summary page, and as an artifact of its own run. Remove the workflow_run workflow, which would otherwise produce a duplicate. Also save the rows as JSON next to the table and compare each run with the newest main run that has them: a "Changes vs main" section lists only the rows whose SEC result, output coverage, or CI status differ, and every row gains the main runtime and relative change. SEC-step fallback timings are shown but not compared, and a missing or malformed baseline is reported and ignored rather than trusted. Without a baseline the table is unchanged. --- .github/workflows/regress-sec-summary.yml | 70 ------------ .github/workflows/regress-sec.yml | 120 ++++++++++++++++++++ docs/sec-regression-summary.md | 36 ++++-- regress/summarize_sec_regress.py | 127 ++++++++++++++++++++-- test/sec/test_sec_regress_summary.py | 95 ++++++++++++++++ 5 files changed, 363 insertions(+), 85 deletions(-) delete mode 100644 .github/workflows/regress-sec-summary.yml diff --git a/.github/workflows/regress-sec-summary.yml b/.github/workflows/regress-sec-summary.yml deleted file mode 100644 index 06ec1019..00000000 --- a/.github/workflows/regress-sec-summary.yml +++ /dev/null @@ -1,70 +0,0 @@ -name: SEC regression summary - -on: - workflow_run: - workflows: [regress-sec] - types: [completed] - -permissions: - contents: read - actions: read - -jobs: - summarize: - runs-on: ubuntu-22.04 - timeout-minutes: 10 - steps: - # workflow_run uses the default branch.

and keep decided pairs in relation learning The learner's size gate summed each register's cone separately, so shared logic was counted once per register and real designs never reached the solver. - Split the candidates into partitions instead of giving up (Mishchenko et al., ICCAD 2008, section 3.3). - Replay each counterexample on the original transitions next to random states, so one counterexample refines all candidates (Mony et al., DAC 2005, section 3.2). - When a partition is undecided, ask each pair separately and drop only the undecided ones instead of discarding everything (Mony et al., sections 2 and 4.1). tinyrocket self-SEC (PDR, dual-rail) goes from 8/132 outputs to 132/132, so the CLI test now expects a full proof. docs/sec-internal-relations.md describes the flow and its limits. --- docs/sec-internal-relations.md | 85 ++++++ src/sec/proof/InternalRelations.cpp | 285 ++++++++++++++---- .../strategies/miter/KeplerFormalCliTests.cpp | 2 +- 3 files changed, 304

hold +the same value. Every proved pair is handed to the proof engines as an +invariant, which turns a proof over two unrelated state spaces into a proof +over one. The pass is optional (`learn_internal_relations`, default `true`) and +lives in `src/sec/proof/InternalRelations.cpp`. + +A learned relation is never trusted because of how it was guessed. It is used +only after a SAT proof over the original transitions and the boot state. + +## 1. Guessing candidate pairs + +`learnInternalStateRelations` pairs two state bits when either holds: + +- **Same full name.** Both have the same display name: the full instance path + from the top, the pin name and the bit, for example `core.csr.reg_mie.Q[0]`. + Memory cells are named from the instance path plus cell and bit index. The + strings must match exactly, so a flow that renames or flattens instances + produces no candidate for the affected registers. +- **Same driver.** Inside one design, both have the identical next-state + expression. + +Candidates are not guessed from simulation. + +In the dual-rail encoding a candidate equates both rails of the two registers. +With `allow_x_equality_in_internal_relations: false` it also requires both +registers to be binary-defined. + +## 2. Base case + +A candidate is kept only if its equalities already hold in the initial state +assignments, and both registers have a transition. + +## 3. Inductive step + +`proveInternalRelations` looks for the largest subset of candidates that is +jointly 1-step inductive: if every pair is equal now, every pair is equal after +one transition. + +- **Speculative reduction.** The hypotheses are applied by literal + substitution: both registers of a pair share one current-frame literal. The + two sides' transitions are then encoded over the same literals, so identical + logic collapses structurally and needs no search. (Mony et al., DAC 2005; + Mishchenko et al., ICCAD 2008, section 3.2.) +- **Partitioning.** One-step register correspondence needs a single time frame, + so the candidates are split into partitions bounded by solver variables. + Every hypothesis is merged in every partition and each candidate is proved in + exactly one, so splitting loses no relation. A large design is split rather + than skipped. (Mishchenko et al., section 3.3.) +- **Query.** Each partition asks whether some candidate in it can differ in the + next frame. + - UNSAT: all of its candidates hold under the hypotheses. + - SAT: the counterexample is replayed (below). + - Undecided within budget: each pair of that partition is asked separately + on the same solver with its own budget, and only the pairs that stay + undecided are dropped. (Mony et al., sections 2 and 4.1.) + +## 4. Refinement by simulation + +A counterexample is replayed on the original transitions as one of 64 parallel +patterns; the other 63 are random states that also satisfy the hypotheses. The +replay runs for up to 16 steps, and every candidate seen differing on a valid +pattern is dropped. One counterexample therefore refines all candidates, not +only the pairs the solver model happens to separate. (Mony et al., section +3.2.) + +Simulation only drops candidates. It never proves one. + +## 5. Fixed point + +Dropping a hypothesis weakens every other proof, so the rounds repeat with a +fresh encoding. The survivors are returned only after a whole round drops +nothing; if the round limit is reached first, nothing is returned. + +## What it does and does not help + +- Two designs with the same register names and near-identical logic behind + them are proved quickly, because the merged transitions collapse. +- Designs that really differ keep only the registers the difference cannot + reach; the output check still reports the counterexample. +- Equivalent designs whose logic was rebuilt (for example synthesis netlist + versus final netlist) prove few pairs: register equalities alone are often + not inductive there. Mishchenko et al. address this with signal + correspondence, which also relates internal nodes. That is not implemented. diff --git a/src/sec/proof/InternalRelations.cpp b/src/sec/proof/InternalRelations.cpp index acb19ae3..b2d2d442 100644 --- a/src/sec/proof/InternalRelations.cpp +++ b/src/sec/proof/InternalRelations.cpp @@ -3,8 +3,11 @@ #include "proof/InternalRelations.h" +#include #include +#include #include +#include #include #include @@ -14,6 +17,132 @@ namespace KEPLER_FORMAL::SEC { +namespace { + +// One bit per simulation pattern. +using Words = std::unordered_map; + +uint64_t evaluateWords(BoolExpr* root, Words& leaves, std::mt19937_64& random, + std::unordered_map& values) { + std::vector stack{root}; + while (!stack.empty()) { + BoolExpr* node = stack.back(); + if (values.contains(node)) { + stack.pop_back(); + continue; + } + if (node->getOp() == Op::VAR) { + // Constants are Var(0) and Var(1).

On nangate45_black_parrot_sec_final that is 5.3M variables and about 2 GiB per partition, and the learner peaked at 16.3 GiB. The partition encoders now create a variable when the encoded logic first mentions a symbol, and apply the hypothesis merge through the encoder's symbol map. Dual-rail validity clauses are added only for the rails a partition uses. The clauses for the pairs being proved are unchanged. black_parrot round 0: about 5.8 GiB to 2.5 GiB per partition, peak 16.3 GiB to 13.2 GiB, 347 s to 284 s.
