Subject: [PATCH 01/30] Fix --fit crash and duplicate column key

- Import UniformMod from nd directly; it is no longer an attribute of
  NoiseDistribution, which made every --fit invocation fail
- Split the duplicated LWE_NUM key into LWE_USVP_NUM and LWE_BDD_NUM so the
  uSVP numerical estimate is no longer overwritten by the BDD one

Subject: [PATCH 02/30] Add --seed and expose the missing distribution flags

- Seed the randomised solvers so repeated runs agree
- Register --s-std, --s-a, --s-b, --s-eta and --q with getopt; they were read
  but never accepted, making four distributions unreachable
- Drop the unimplemented --file option
- Label the log q columns correctly in --param logq --table

Subject: [PATCH 04/30] Update dependencies, docs and command files

- Add lmfit to requirements.txt
- Ignore output.csv, compiled_output.csv and debug_log.txt
- Point docker-compose at directories that exist
- Remove the --file examples from the README
- Correct n_tables.txt to match Tables 7 and 9
- Renumber equation references in formulas.py to the JoC version

+Reproducibility
+---------------
 
-Find an estimation of the standard deviation of the error distribution, given the example parameters in `example_error_binary.csv`:
+Several numerical solvers (the hybrid attack, and ``--param std_e``) restart from randomised initial points. Both random number generators are seeded at start-up so that a given command line always produces the same answer; pass ``--seed`` to change it.
 
-.. code-block:: yaml
+The fitted constants in ``src/const.py`` can be regenerated from ``dataset/`` with:
 
-   command: ["sage", "--python3", "src/estimate.py", "--param", "error", "--file", "./examples/example_error_binary.csv"]
+.. code-block:: bash
 
-**Note**: In the Docker version, we applied a change to the `Lattice Estimator <https://github.com/malb/lattice-estimator>`_ to address an imprecision in the case where the standard deviation of the error distribution is much larger than ``3.19``.
+   bash find_all_constants.sh
 
 ToDo list
 ----
 
+* Resolve the BDD ``eta`` equation (see the OPEN ITEM note at the top of ``src/numerical_solver.py``).
 * Include meet-in-the-middle for the hybrid attack. Challenge: derive compact formula for admissibility probability. Current status: added equations for optimization that include mitm speed-up for enumeration. Not tested.
 * Improve runtime of numerical_lambda_hybrid(). Compute probability_enum() and babai_prob() on the log scale directly.

+# Regenerated tables
+
+Everything here is produced by `regenerate_tables.sh` at the repository root:
+
+```bash
+bash regenerate_tables.sh            # all tables
+bash regenerate_tables.sh 2_4 18     # selected tables
+```
+
+Runs are seeded (`SEED`, default 0), so repeated invocations give identical
+files. Without a seed the hybrid solver and `--param std_e` restart from
+randomised initial points and drift by a bit or two between runs.
+
+## Which file holds which table
+
+Several paper tables are two views of one run: a uSVP table and its BDD
+counterpart share a command and differ only in the columns quoted. Those are
+stored once, under both numbers.
+
+| File | Paper table | Columns for that table |
+| --- | --- | --- |
+| `table_02_04_lambda_binary.csv` | 2 | `usvp` = Eq. (25), `usvp_s` = Eq. (27), `est usvp` |

+| `table_20_examples.csv` | 20 | `output` |
+
+Columns prefixed `est ` come from the Lattice Estimator with the BDGL16 cost
+model, reported as `floor(log2(rop))`. A `*` prefix marks a value after the
+`-c` correction loop.
+
+## Status
+
+The BDD `eta` question is settled: the code is correct and Section 5 of the
+paper is not. Everything in this directory uses the settled equation.
+
+Section 5's BDD system should read `lambda - (0.292*eta + 16.4) = 0` for its
+third equation, matching `T_SVP(eta) = 2^(0.292*eta + 16.4)` in Section 3.2.
+Tables 14, 15, 16 and 17 in the paper must be replaced from the files here.
+
+## Known issues these files will show
+
+- `--param logq` reports `output = min(logq usvp, logq bdd)`. A larger modulus
+  is weaker, so the binding constraint is the attack tolerating the smaller
+  one. Note that `est usvp` and `est bdd` are each measured at their own
+  attack's log q rather than at `output`, so read the row as two independent
+  results plus a recommendation, not as three views of one value.
+
+- Table 20's four rows do not reproduce the values printed in the paper, and
+  two of the printed rows are short of their claimed security level: (110,
+  512, 17) measures 102 bits and (110, 3072, 101) measures 101 bits.

Subject: [PATCH 07/30] Report the smaller modulus in --param logq

A larger modulus is weaker, so the binding constraint is the attack tolerating
the smallest one. Taking the maximum returned a modulus the other attack
already broke: at lambda=110, n=512, ternary it gave 16, measuring 109 bits.

Changes the output column of Tables 12, 16 and 20.

Subject: [PATCH 11/30] Derive RNG seeds per solver call

Seeding the global random module once per process made a row's result depend on
how many rows preceded it. Each call now derives its own generator from the base
seed and its own arguments.

-Several numerical solvers (the hybrid attack, and ``--param std_e``) restart from randomised initial points. Both random number generators are seeded at start-up so that a given command line always produces the same answer; pass ``--seed`` to change it.
+Several numerical solvers (the hybrid attack, and ``--param std_e``) restart from randomised initial points. Each such call derives its own generator from a base seed and the call's own parameters, so a given set of LWE parameters always produces the same answer -- independently of how many other rows were computed in the same invocation. Pass ``--seed`` to change the base seed; see ``src/rng.py``.
+
+The hybrid solvers are sensitive to their restart budget. At ``--param logq --lambda 192 --n 1024 --hw 64 --secret sparse`` the default budget can settle on a log q that the Lattice Estimator scores far below the target, while ``--nrestart 1000`` finds the right one. Run the hybrid with ``-v`` and check the reported ``est hybrid`` against your target.
 
 The fitted constants in ``src/const.py`` can be regenerated from ``dataset/`` with:

Subject: [PATCH 12/30] Fix estimator path, --param est and help text

- Resolve the vendored estimator from __file__ rather than the working directory
- Return [] from process_est; the previous ([], []) crashed export_to_csv
- Remove the unused second copy of coreSVP_models
- Document --seed, --q and the --s-* options; -v is not --verify
- Replace a bare except in parse_logq and an uncaught ValueError in
  closest_power_of_2
- Remove test_estimator.py

Subject: [PATCH 13/30] Add test suite and CI workflow

66 tests pinning values printed in the paper, the per-call generators, the
Section 6 examples, and the refitting of all 16 constant sets. Tests needing
SageMath skip themselves when it is absent.

Subject: [PATCH 14/30] Select estimator verdicts by candidate, not by value

Three sites keyed a dict on each formula's output, so two formulas agreeing on
the same number silently discarded one verdict. Candidates are now kept as
pairs.

Subject: [PATCH 15/30] Scope warnings-as-errors and reject degenerate std_e
 roots

- Apply warnings-as-errors to the solver entry points rather than the whole
  process, which had imposed it on the Lattice Estimator
- Reject fsolve roots at beta = 2*pi*e, where the residual vanishes for any
  standard deviation
- Add cost_bits() so an infinite estimator cost no longer raises OverflowError

Tables 2, 4, 12, 13, 16, 17 and 20 regenerate unchanged.

Subject: [PATCH 16/30] Add build_row() and convert two functions

Replaces the dict literals in process_n_param and create_data_point, six
branches each. build_row() raises on a repeated column, which is how the
duplicated LWE_NUM key went unnoticed.

Tables 2-12 and 20 regenerate unchanged.

Subject: [PATCH 17/30] Convert the remaining row literals to build_row()

No dict literals left, down from 26. Keeps the pre-correction snapshots in
process_std_e_param, which are not aliases: the correction branch substitutes a
failed solver's value before using them.

Tables 12, 13, 16, 17 and 20 regenerate unchanged.

Subject: [PATCH 19/30] Update the docs to match the tool

- Regenerate every tutorial's output; all of it predated master, and
  tutorial_stde had its uSVP and BDD columns swapped
- Remove --file, ./examples/ and --verify, none of which exist
- Document the real distribution options in tutorial_non_fhe
- Fold modules.rst into api.rst and delete tutorial_ntru.rst, a duplicate
- Remove the duplicate python: key from .readthedocs.yaml
- Add a Reproducibility page

Sphinx builds with no warnings, down from ten.

-A Tool for Fast and Secure LWE Parameter Selection
-===================================================
+Introduction
+============
 
 We offer a tool to select secure parameters for LWE-based applications in a fast and flexible way. The tool can provide you with any of the following parameters: security level, size of the ciphertext modulus, LWE dimension, and standard deviation of the error distribution.
 
 Our tool is constructed by studying the uSVP, BDD and Hybrid attacks against LWE. From this study, we derive formulas that describe each of the aforementioned parameters as a function of the others. You can find all the details in this paper: `A Tool for Fast and Secure LWE Parameter Selection: the FHE case <https://eprint.iacr.org/2024/1895>`_.

-Observe that given the output of the numerical methods, we obtain a security level of `177` for the USVP attack and `190` for the BDD attack. We can get closer to the optimal values by using the Lattice Estimator. 
+The uSVP solver's value already reaches the target, but the BDD solver's
+`26.02` measures at only 177 bits against a target of 192.
 
-**Appling the correction**
+**Applying the correction**
 
-By adding the option ``--correct`` or ``-c``, we can find the optimal values for the ciphertext modulus and the standard deviation of the error distribution. The output will show the corrected values.
+Adding ``-c`` walks each value towards the target in steps of 0.1, calling the
+Lattice Estimator at each step, and reports both the corrected value and how
+many calls it took.

 General LWE Parameters
 ======================
 
-While our formulas are fine-tuned for FHE settings, our tool allows users to input arbitrary LWE parameters :math:`(\lambda, n, \sigma_e, \sigma_s, q)`.
-
-In particular, :math:`\sigma_s` and :math:`\sigma_e` can be chosen from the following distributions:
-
-- **Uniform binary distribution** :math:`\mathcal{U}_2`:
-  Use the command ``--secret "binary"``.
-
-- **Uniform ternary distribution** :math:`\mathcal{U}_3`:
-  Use the command ``--secret "ternary"``.
-
-- **Uniform modulus distribution** :math:`\mathcal{U}_p`:
-  Use the command ``--secret "uniformmod" --p "5"``.
-
-- **Uniform distribution** :math:`\mathcal{U}_{[a,b]}`:
-  Use the command ``--secret "uniform" --a "-1" --b "1"``.
-
-- **Sparse ternary distribution** :math:`\mathcal{HWT}(h)`:
-  Use the command ``--secret "sparse" --hw "128"``, where ``hw`` is the Hamming weight :math:`h`.
-
-- **Discrete Gaussian distribution** :math:`\mathcal{D}_{\mathbb{Z}, \sigma^2}`:
-  Use the command ``--secret "gaussian" --sig "3.19"``.
-
-- **Centered binomial distribution** :math:`\psi_\eta`:
-  Use the command ``--secret "binomial" --eta "21"``.
-
-In this case, we recommend using the option ``--num-only``, which disables the fine-tuned formulas and runs only our numerical solver.
-
-To evaluate the security of the Kyber scheme with :math:`n = 512` and :math:`\log q = 11`, use the following command:
+The formulas are fine-tuned for FHE settings, but the tool accepts arbitrary
+LWE parameters :math:`(\lambda, n, \sigma_e, \sigma_s, q)`.

+below. Options without the ``s-`` prefix set the **error**; the ``s-`` prefixed
+form sets the **secret**.

Subject: [PATCH 20/30] Add overview, limitations and options pages

- overview.rst: what the tool computes and how the columns relate
- limitations.rst: no dual or quantum attacks, the fitted range, the hybrid
  log q weakness, the broken --ntru
- options.rst: all twenty command line options

Rewrites introduction.rst as a landing page rather than a copy of the README,
and splits the index into Getting started, Tutorials and Reference.

 Introduction
 ============
 
-We offer a tool to select secure parameters for LWE-based applications in a fast and flexible way. The tool can provide you with any of the following parameters: security level, size of the ciphertext modulus, LWE dimension, and standard deviation of the error distribution.
+A tool for choosing secure parameters for LWE-based schemes, quickly.
 
-Our tool is constructed by studying the uSVP, BDD and Hybrid attacks against LWE. From this study, we derive formulas that describe each of the aforementioned parameters as a function of the others. You can find all the details in this paper: `A Tool for Fast and Secure LWE Parameter Selection: the FHE case <https://eprint.iacr.org/2024/1895>`_.
+Selecting parameters for Fully Homomorphic Encryption means balancing a
+ciphertext modulus large enough to evaluate your circuit against a lattice
+problem hard enough to be secure. The usual route is to run an LWE estimator
+over candidate parameters until something fits, which is slow, or to pick from
+a published table, which is rigid.
 
-Basic Usage
-----------------------------

-We present the basic usage of the tool below. For more advanced usage, please refer to the `readthedocs <https://fastparameterselection.readthedocs.io/en/latest/>`_ section.
-
-Find an estimation of the security level by running:
+This tool takes a third route. Starting from the complexity of the best known
+lattice attacks, it derives closed-form relations between the LWE parameters,
+so any one of them can be computed directly from the others. See
+:doc:`overview` for what that means in practice, and the paper for the
+derivations: `A Tool for Fast and Secure LWE Parameter Selection: the FHE case
+<https://eprint.iacr.org/2024/1895>`_.

-Dependencies
+Installation
 ------------
 
-We have added the functionality to compare the output of our formulas against the `Lattice Estimator <https://github.com/malb/lattice-estimator>`_. We also use it for some of the more advanced features of our tool. Please use the custom version of the Estimator provided in this repository to avoid unexpected errors. Our code also depends on SageMath, you can follow this `link for an installation guide <https://doc.sagemath.org/html/en/installation/index.html>`_. 
-
 
-The following Python libraries are required:
-- `Numpy <https://numpy.org/>`_
-- `SciPy <https://scipy.org/>`_
 
-You can install the dependencies by running:
-
-.. code-block:: bash

 Use with Docker
 ---------------
 
-You can build and run the repository with Docker using the following command:
-
-.. code-block:: bash
-
-   docker-compose -f ./docker/docker-compose.yaml up --build
-
-To only run the container, use:
-
-.. code-block:: bash
-
-   docker-compose -f ./docker/docker-compose.yaml up
-
-Currently, it runs `estimate.py` to obtain the parameter ``lambda``, given ``n = 1024``, ``logq = 35``, binary secret distribution, and standard deviation of the error distribution ``3.19``. To run the estimation with your parameters, you can modify the command line in `docker-compose.yaml` as follows:
-
-Find an estimation of the security level:
-
-.. code-block:: yaml
-
-   command: [ "sage", "--python3", "src/estimate.py", "--param", "lambda",  "--n", "1024", "--logq", "20-30\\;35\\;40-60", "--secret", "binary", "--error", "gaussian", "--std", "3.19"]
-
-Find an estimation of the security level and verify it against the Lattice Estimator:
-
-.. code-block:: yaml
-
-   command: [ "sage", "--python3", "src/estimate.py", "--param", "lambda",  "--n", "1024", "--logq", "20-30\\;35\\;40-60", "--secret", "binary", "--error", "gaussian", "--std", "3.19", "-v" ]
-
-Find an estimation of the LWE dimension:
-
-.. code-block:: yaml
-
-   command: ["sage", "--python3", "src/estimate.py", "--param", "n",  "--lambda", "80", "--logq", "20", "--secret", "binary", "--error", "gaussian", "--std", "3.19"]
-
-Find an estimation of the size of the modulus q:
-
-.. code-block:: yaml
-
-   command: ["sage", "--python3", "src/estimate.py", "--param", "logq",  "--lambda", "80", "--n", "1024", "--secret", "binary", "--error", "gaussian", "--std", "3.19"]
-
-Find an estimation of the standard deviation of the error distribution:
-
-.. code-block:: yaml
-
-   command: ["sage", "--python3", "src/estimate.py", "--param", "std_e",  "--lambda", "80", "--n", "1024", "--logq", "20", "--secret", "binary"]
-
-**Note**: for a standard deviation of the error much larger than ``3.19``, the Lattice Estimator becomes imprecise, so the ``est bdd`` column of ``--param std_e`` should be treated as indicative only.
-
-Reproducibility
----------------
-
-Several numerical solvers (the hybrid attack, and ``--param std_e``) restart from randomised initial points. Each such call derives its own generator from a base seed and the call's own parameters, so a given set of LWE parameters always produces the same answer -- independently of how many other rows were computed in the same invocation. Pass ``--seed`` to change the base seed; see ``src/rng.py``.
-
-The hybrid solvers are sensitive to their restart budget. At ``--param logq --lambda 192 --n 1024 --hw 64 --secret sparse`` the default budget can settle on a log q that the Lattice Estimator scores far below the target, while ``--nrestart 1000`` finds the right one. Run the hybrid with ``-v`` and check the reported ``est hybrid`` against your target.
-
-The fitted constants in ``src/const.py`` can be regenerated from ``dataset/`` with:
-
-.. code-block:: bash
-
-   bash find_all_constants.sh
-
-Tests
------
-
-.. code-block:: bash
-
-   pip install pytest
-   python3 -m pytest              # everything
-   python3 -m pytest -m "not slow"  # skip refitting the constants
-
-The suite pins values printed in the paper, so a change to a formula that
-would move a published table fails the build. Tests marked ``needs_sage`` run
-the command line and skip themselves when SageMath is not installed; the rest
-cover the formulas, the numerical solvers and the per-call generators and need
-only numpy and scipy.
-
-ToDo list
----------
 
-* Resolve the BDD ``eta`` equation (see the OPEN ITEM note at the top of ``src/numerical_solver.py``).
-* Include meet-in-the-middle for the hybrid attack. Challenge: derive compact formula for admissibility probability. Current status: added equations for optimization that include mitm speed-up for enumeration. Not tested.
-* Improve runtime of numerical_lambda_hybrid(). Compute probability_enum() and babai_prob() on the log scale directly.

+Limitations
+===========
+
+The tool reports a security level, so it is worth being precise about what
+that number does and does not cover.
+
+What is not modelled
+--------------------
+
+**Dual attacks.** Only primal attacks are considered. The efficient dual
+attacks of [GJ21]_ and [MATZOV]_ rely on heuristics shown to fail in
+[DP23]_, and the provable variants are weaker than the primal attacks at
+these parameters. If a corrected dual analysis lands, these estimates would
+need revisiting.
+
+**Quantum attacks.** All costs are classical, in the core-SVP model with the
+BDGL16 sieving cost.
+
+**Correctness of decryption.** The tool answers only the security question.
+Whether a parameter set supports the circuit you want to evaluate depends on
+noise growth in your scheme, which is out of scope.
+
+Where the formulas apply
+------------------------
+
+The constants in ``src/const.py`` were fitted against Lattice Estimator data
+at :math:`\sigma_e = 3.19`, for binary and ternary secrets, over
+:math:`n \in [2^{10}, 2^{15}]`. They hold up beyond that range -- the paper
+checks :math:`n = 2^{16}` and :math:`2^{17}` -- but the further you go, the
+more you are extrapolating. Outside the fitted setting the tool falls back to
+the numerical solvers automatically.
+
+The model was tuned to slightly *under*-estimate security rather than over-
+estimate it. Discrepancies of a few bits against the Lattice Estimator are
+expected and acceptable.
+
+Known weaknesses
+----------------
+
+**The hybrid log q search is not reliable.** ``--param "logq"`` with
+``--secret "sparse"`` can return a modulus whose measured security is below
+the target. The solver checks each candidate against its own lambda model, but
+that model and the Lattice Estimator disagree by anywhere from 2 to 100 bits,
+so the check cannot underwrite the answer. Always run this combination with
+``-v`` and compare ``est hybrid`` against your target.
+
+**The Lattice Estimator loses precision for large errors.** When
+:math:`\sigma_e` is far from `3.19` -- as it is for much of
+``--param "std_e"`` -- the ``est`` columns should be read as indicative.
+
+**Numerical solvers can fail to converge.** They restart from randomised
+initial points and give up after a bounded number of attempts. A failure is
+reported as a fallback value with an estimator verdict of `0`, which is a
+signal to rerun with a different ``--seed`` or to use the closed forms.
+
+**Local optima.** The solvers may settle on a solution that is not the best
+available. Restarting with a different ``--seed``, or raising ``--nrestart``
+for the hybrid, sometimes finds a better one.
+
+**NTRU checking does not work.** The ``--ntru`` option reports every parameter
+set as overstretched and should not be relied on.
+
+Verifying a result
+------------------
+
+The tool is a fast way to narrow the search, not a replacement for an
+estimator. Once you have candidate parameters, confirm them:
+
+.. code-block:: bash
+
+   python3 src/estimate.py --param "lambda" --n "1024" --logq "27" \
+      --secret "binary" --error "gaussian" --std "3.19" --table -v
+
+The ``est`` columns are the Lattice Estimator's verdict under the BDGL16 cost
+model. You can also check against an independent tool such as the
+`Leaky-LWE Estimator <https://github.com/lducas/leaky-LWE-Estimator>`_.

+These are not independent. Raising :math:`q` lets a scheme evaluate a deeper

+navigating that trade-off.
+
+The tool inverts the relation in whichever direction you need: **fix any three
+and it solves for the fourth.** :math:`\sigma_s` is the exception -- it is

+
+The attacks
+-----------
+
+Three lattice attacks are modelled, all of them *primal*:
+
+**uSVP** -- embed the instance in a lattice where the secret is an unusually
+short vector, then run BKZ until it surfaces.
+
+**BDD** -- treat the instance as bounded distance decoding: reduce, solve SVP
+on a projected sublattice, then lift with Babai's algorithm.
+
+**Hybrid** -- guess part of a sparse secret and solve BDD on what remains.
+Only relevant when the secret has low Hamming weight, so it is used for
+``--secret "sparse"``.
+
+Dual attacks are deliberately **not** modelled; see :doc:`limitations`.
+
+Since an attacker uses whichever is cheapest, the ``output`` column reports
+the weakest link: the *lowest* security level, the *largest* dimension, the
+*smallest* modulus, the *largest* error.
+
+Two ways of answering
+---------------------
+
+For each attack the tool carries two independent routes to the same relation,
+and ``--table`` shows both:
+
+**Closed-form formulas** (columns ``usvp``, ``bdd``, and the simplified
+``usvp_s``, ``bdd_s``) come from the complexity analysis in Section 3 of the
+paper, with their lower-order terms fitted against the Lattice Estimator in
+Section 4. They are instant and numerically stable, but the fit was done at
+:math:`\sigma_e = 3.19` for binary and ternary secrets.
+
+**Numerical solvers** (columns ``usvp num``, ``bdd num``) solve the same
+systems directly with ``scipy``. They are slower and occasionally fail to
+converge, but they carry no fitted constants, so they apply to any parameters.
+Outside the fitted setting the tool selects them automatically; ``--num-only``
+forces them.
+
+Agreement between the two is a useful signal. Where they diverge, ``-v`` gives
+the Lattice Estimator's own verdict as the tie-breaker.

Subject: [PATCH 21/30] Add packaging and rename src to fastparameterselection

- Add pyproject.toml with a fastparams console script
- Convert 18 intra-project imports to relative
- Invoke as python3 -m fastparameterselection.estimate; the file can no longer
  be run by path
- Use the vendored estimator when present, else a normally importable one

SageMath still cannot be installed by pip; the README says so. Building needs
setuptools >= 61, or the wheel is silently empty.

-Dependencies
+Installation
 ------------
 
-We have added the functionality to compare the output of our formulas against the `Lattice Estimator <https://github.com/malb/lattice-estimator>`_. We also use it for some of the more advanced features of our tool. Please use the custom version of the Estimator provided in this repository to avoid unexpected errors. Our code also depends on SageMath, you can follow this `link for an installation guide <https://doc.sagemath.org/html/en/installation/index.html>`_. 
+SageMath is required and **cannot be installed by pip**: ``nd.py`` imports
+``sage.all``, and the Lattice Estimator used by ``-v`` is a Sage library.
+Install Sage first, by whichever route suits your system:
 
+.. code-block:: bash
+
+   sudo apt install sagemath          # Debian/Ubuntu
+   conda install -c conda-forge sage  # conda
+
+Then install this package into that interpreter:
+
+.. code-block:: bash
+
+   pip install git+https://github.com/Crypto-TII/fastparameterselection
+
+which provides a ``fastparams`` command:
+
+.. code-block:: bash
 
-The following Python libraries are required:
-- `Numpy <https://numpy.org/>`_
-- `SciPy <https://scipy.org/>`_
+   fastparams --param "lambda" --n "1024" --logq "27" --secret "binary" --std "3.19"
+
+From a checkout, without installing, the module form works too:
+
+.. code-block:: bash
+
+   python3 -m fastparameterselection.estimate --param "lambda" --n "1024" --logq "27" --secret "binary" --std "3.19"
+
+Building the package needs ``setuptools >= 61`` for PEP 621 support; older
+versions silently produce an empty ``UNKNOWN`` wheel.
+
+The remaining Python dependencies (numpy, scipy, lmfit) are installed
+automatically. The Lattice Estimator is vendored in the repository, so ``-v``
+works from a checkout; after a pip install it is used only if an ``estimator``
+package is importable.
+
+Common errors
+-------------
 
-You can install the dependencies by running:
+Some MacOS users may encounter an error running the tool with ``python3``.

Subject: [PATCH 22/30] Rewrite the README

- Regenerate all four examples; they printed "Uniform (-1 0)" and two had wrong
  numbers
- Fix --error "3.19", which exited with "Error distribution not supported"
- Fix sage-python3, which is not a command
- Unescape the log q separators in the Docker examples; docker-compose uses no
  shell, so parse_logq rejected them
- Remove the duplicated "Common errors" section
- Put installation before usage and add a section on what the tool does not
  cover

 A Tool for Fast and Secure LWE Parameter Selection
 ===================================================
 
-We offer a tool to select secure parameters for LWE-based applications in a fast and flexible way. The tool can provide you with any of the following parameters: security level, size of the ciphertext modulus, LWE dimension, and standard deviation of the error distribution.
+Select secure parameters for LWE-based schemes without running a lattice
+estimator over every candidate. The security level, the LWE dimension, the
+ciphertext modulus and the error standard deviation are mutually constrained:
+fix any three and this tool solves for the fourth.
 
-Our tool is constructed by studying the uSVP, BDD and Hybrid attacks against LWE. From this study, we derive formulas that describe each of the aforementioned parameters as a function of the others. You can find all the details in this paper: `A Tool for Fast and Secure LWE Parameter Selection: the FHE case <https://eprint.iacr.org/2024/1895>`_.
+It is built on an analysis of the uSVP, BDD and hybrid attacks, from which
+closed-form relations between the parameters are derived. The details are in
+the paper: `A Tool for Fast and Secure LWE Parameter Selection: the FHE case
+<https://eprint.iacr.org/2024/1895>`_.
 
-Basic Usage
-----------------------------
+Full documentation, including what the tool does **not** cover, is at
+`readthedocs <https://fastparameterselection.readthedocs.io/en/latest/>`_.
 
-We present the basic usage of the tool below. For more advanced usage, please refer to the `readthedocs <https://fastparameterselection.readthedocs.io/en/latest/>`_ section.
+Installation
+------------
 
-Find an estimation of the security level by running:
+SageMath is required and **cannot be installed by pip**: ``nd.py`` imports
+``sage.all``, and the Lattice Estimator used by ``-v`` is a Sage library.
+Install Sage first, by whichever route suits your system:
 
 .. code-block:: bash
 
-   python3 -m fastparameterselection.estimate --param "lambda" --n "1024" --logq "20;35;40" --secret "binary" --std "3.19"
+   sudo apt install sagemath          # Debian/Ubuntu
+   conda install -c conda-forge sage  # conda
 
-.. code-block:: text
+Then install this package into that interpreter:
 
-   secret dist.   | lwe dim. | log q | output
-   ---------------+----------+-------+-------
-   Uniform (-1 0) | 1024     | 20    | 173   
-   Uniform (-1 0) | 1024     | 35    | 95    
-   Uniform (-1 0) | 1024     | 40    | 83    
+.. code-block:: bash
 
-Find an estimation of the LWE dimension required to obtain a given security level:
+   pip install git+https://github.com/Crypto-TII/fastparameterselection
+
+which provides a ``fastparams`` command:
 
 .. code-block:: bash
 
-   python3 -m fastparameterselection.estimate --param "n" --lambda "80" --logq "20-23" --secret "binary" --std "3.19"
+   fastparams --param "lambda" --n "1024" --logq "27" --secret "binary" --std "3.19"
 
-.. code-block:: text
+From a checkout, without installing, the module form works too:
 
-   secret dist.   | lambda | log q | output | pow
-   ---------------+--------+-------+--------+----
-   Uniform (-1 0) | 80     | 20    | 514    | 512
-   Uniform (-1 0) | 80     | 21    | 538    | 512
-   Uniform (-1 0) | 80     | 22    | 562    | 512
-   Uniform (-1 0) | 80     | 23    | 586    | 512
+.. code-block:: bash
 
-Find an estimation of the size of the modulus q:
+   python3 -m fastparameterselection.estimate --param "lambda" --n "1024" --logq "27" --secret "binary" --std "3.19"
 
-.. code-block:: bash
+Building the package needs ``setuptools >= 61`` for PEP 621 support; older
+versions silently produce an empty ``UNKNOWN`` wheel.
 
-   python3 -m fastparameterselection.estimate --param "logq" --lambda "80" --n "1024" --secret "binary" --error "3.19"
+The remaining Python dependencies (numpy, scipy, lmfit) are installed
+automatically. The Lattice Estimator is vendored in the repository, so ``-v``
+works from a checkout; after a pip install it is used only if an ``estimator``
+package is importable.
 
-.. code-block:: text
+On some MacOS setups ``python3`` cannot see Sage even when it is installed. Run
+the tool through Sage itself in that case:
 
-   secret dist.   | lambda | lwe dim. | output
-   ---------------+--------+----------+-------
-   Uniform (-1 0) | 80     | 1024     | 42

-----------------------------
-Some MacOS users may encounter an error when running the tool using `python3 -m fastparameterselection.estimate`. This is due to the fact that the tool requires SageMath to run. To resolve this issue, you can run the tool using SageMath directly:

+Add ``--table`` to see each formula and solver separately, and ``-v`` to check

-From a checkout, without installing, the module form works too:
+Before you rely on a result
+---------------------------
+
+The tool answers the security question only, and not every part of it. It does
+not model dual or quantum attacks, says nothing about whether a parameter set
+supports your circuit, and its fitted constants were learned at a standard
+deviation of 3.19 for binary and ternary secrets. The hybrid ``--param logq``
+search can return a modulus below the target, and ``--ntru`` is known to be
+broken.
+
+The full list is on the `limitations
+<https://fastparameterselection.readthedocs.io/en/latest/limitations.html>`_
+page. Confirm candidate parameters with ``-v`` before deploying them.
+
+Reproducibility
+---------------
+
+Several numerical solvers (the hybrid attack, and ``--param std_e``) restart from randomised initial points. Each such call derives its own generator from a base seed and the call's own parameters, so a given set of LWE parameters always produces the same answer -- independently of how many other rows were computed in the same invocation. Pass ``--seed`` to change the base seed; see ``fastparameterselection/rng.py``.
+
+The hybrid solvers are sensitive to their restart budget. At ``--param logq --lambda 192 --n 1024 --hw 64 --secret sparse`` the default budget can settle on a log q that the Lattice Estimator scores far below the target, while ``--nrestart 1000`` finds the right one. Run the hybrid with ``-v`` and check the reported ``est hybrid`` against your target.
+
+The fitted constants in ``fastparameterselection/const.py`` can be regenerated from ``dataset/`` with:
 
 .. code-block:: bash
 
-   python3 -m fastparameterselection.estimate --param "lambda" --n "1024" --logq "27" --secret "binary" --std "3.19"
+   bash find_all_constants.sh
 
-Building the package needs ``setuptools >= 61`` for PEP 621 support; older
-versions silently produce an empty ``UNKNOWN`` wheel.
+The tables of the paper can be regenerated with:
 
-The remaining Python dependencies (numpy, scipy, lmfit) are installed
-automatically. The Lattice Estimator is vendored in the repository, so ``-v``
-works from a checkout; after a pip install it is used only if an ``estimator``
-package is importable.
+.. code-block:: bash
 
-Common errors
--------------
+   bash regenerate_tables.sh
 
-Some MacOS users may encounter an error running the tool with ``python3``.
-This is because the tool requires SageMath. Run it through Sage instead:
+Results land in ``tables/``; ``tables/README.md`` maps columns to tables.

-* Include meet-in-the-middle for the hybrid attack. Challenge: derive compact formula for admissibility probability. Current status: added equations for optimization that include mitm speed-up for enumeration. Not tested.
-* Improve runtime of numerical_lambda_hybrid(). Compute probability_enum() and babai_prob() on the log scale directly. 
+* Include meet-in-the-middle for the hybrid attack. Challenge: derive a compact formula for the admissibility probability. Current status: equations for the optimisation including the mitm speed-up for enumeration are in place, untested.

Subject: [PATCH 24/30] Correct the installation instructions and the help text

Installing from a copy loses the vendored Lattice Estimator, which is resolved
relative to the package, so -v silently stops working. Recommend an editable
install from a checkout instead.

- Note that editable installs need setuptools >= 64, not 61, and that an older
  pip resolves its isolated build environment to the system setuptools, which
  builds an empty UNKNOWN wheel and exits 0
- Replace "python3 src/estimate.py" in the usage line; src/ no longer exists
- Replace the --fit examples, which named a fit_formula.py that does not exist
  and a --dist option that is not the one the fit reads

Subject: [PATCH 26/30] Fix the Docker image

- Import fit_formula inside the --fit branch; at module level it pulled in
  lmfit, which a SageMath install does not provide, so the container failed
  with ModuleNotFoundError before printing anything
- Install lmfit in the image and correct the stale src/nd.py path in
  requirements.txt

- actions/checkout failed with EACCES inside the job-level container: the image
  runs as the unprivileged sage user while the runner owns its workspace as
  root, and running the container as root makes Sage ignore --python3
- Check out on the host and mount the tree read-only into a per-step container,

 * Include meet-in-the-middle for the hybrid attack. Challenge: derive a compact formula for the admissibility probability. Current status: equations for the optimisation including the mitm speed-up for enumeration are in place, untested.
 * Improve the runtime of ``numerical_lambda_hybrid()``. Computing ``probability_enum()`` and ``ss_enum()`` on the log scale is both faster and removes their dependency on Sage; a prototype agreed with the current code to 1e-10 and ran up to 750x faster.
 * Make the hybrid ``--param logq`` search reject a modulus its own lambda model does not vouch for, instead of returning it with a warning.
-* Fix ``--ntru``: ``check_overstreched()`` reports every parameter set as overstretched.

+# Tables under the paper's own file names
+
+The files in the directory above are named after the paper tables they feed,
+and each holds one run of the tool. The paper's LaTeX source splits those same
+runs by dimension or by security level, so one file above becomes several here.
+
+Regenerate this directory with:
+
+    python3 tables/to_paper_names.py
+
+The columns and their order match the paper's CSVs, and the LaTeX selects
+columns by name, so these can be copied straight over the paper's `tables/`
+directory.
+
+## Two differences to know about before copying
+
+**The `n_*` files carry one extra column.** The paper's `n_bin_*.csv` and
+`n_ter_*.csv` have a single `est num`; these have `est usvp num` and
+`est bdd num`. The single column was a bug: one dictionary key held both
+numerical estimates, so the uSVP value was overwritten by the BDD one. Tables
+11 and 15 then read the same column while reporting different attacks.
+
+An extra column is harmless on its own, because `pgfplotstable` selects by
+name. But four table environments in `sections/numerical.tex` ask for the
+column that no longer exists, and need editing:
+
+| Line | Currently | Should be | Table |
+| --- | --- | --- | --- |
+| 181 | `columns={log q,lambda,est num,usvp num}` | `est usvp num` | 11 |
+| 201 | `columns={log q,lambda,est num,usvp num}` | `est usvp num` | 11 |
+| 517 | `columns={log q,lambda,est num,bdd num}` | `est bdd num` | 15 |
+| 537 | `columns={log q,lambda,est num,bdd num}` | `est bdd num` | 15 |
+
+**The secret distribution is labelled differently.** These files say `Binary`
+and `Ternary` where the paper's say `Uniform (-1 0)` and `Uniform (-1 1)`. The
+tool's own output changed; no table typesets that column, so this only matters
+if one starts to.
+
+## Not produced here
+
+* `logq_hybrid_2_10.csv`, `logq_hybrid_2_15.csv` — Table 19. Its data file is
+  no longer in the repository, so these cannot be regenerated.
+* Table 20 has no CSV in the paper; it is typeset inline in
+  `sections/tool.tex`.

Subject: [PATCH 30/30] Mark the Equation (35) refits as platform sensitive

- They reproduce const.py here and in sagemath/sagemath:10.3, but land in a
  different minimum on the CI runner, about 1% low on the leading constant
- Non-strict xfail, so a platform that does reproduce them still passes
