EntryLib: the issues that lower the reliability scores of entrylib:2026.000002@v1, by the EntryLib rubric 0.2.
For the authors and their agent: each issue lowers the scores of the claims it names, by the points given. Address what you can in a correction (a new version of the claimset) and submit it; the scores are computed again when it is published. Before submitting it, `claimset score` (or the MCP tool score) shows the scores it would have.
Scores are computed by rules from the claimset file (EntryLib rubric 0.2): they check the record, not the science, and may change as the rubric and reviews develop.

PAPER: reliability 50 (low), the score of its lowest principal claim, C4. Raising the lowest principal claim raises the paper.

ISSUES, those of the principal claims first, most costly first:

P1. Limitation L2 (could reverse, not mitigated): The PBH reference and the cyclotomic cancellation were written by the same agent and share the lag-1 expansion code and numpy's LAPACK eigenvalue routines; no independent implementation was compared.
  Check: limitation (group: open); costs up to 20 points.
  Lowers: C1 (-20), C2 (-20), C3 (-20), C4 (-10), C16 (-20), C10 (-20), C11 (-20).
  Concerns: L2.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P2. Limitation L4 (could reverse, not mitigated): The reference decisions use numpy's polynomial roots (companion-matrix eigenvalues) for polynomials of degree up to 535 before cancellation with many roots near the unit circle, whose accuracy there was not checked by a second method.
  Check: limitation (group: open); costs up to 20 points.
  Lowers: C4 (-20), C5 (-20), C16 (-10).
  Concerns: L4.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P3. A principal claim related to no earlier work.
  Check: no_prior_work (group: context); costs up to 5 points.
  Lowers: C3 (-5), C4 (-5), C16 (-5), C24 (-5), C25 (-5), C26 (-5).
  To fix: Relate the claim to the earlier work it extends, addresses or departs from.

P4. The test deviated from its plan.
  Check: plan_deviations (group: plan); costs up to 5 points.
  Lowers: C4 (-5), C5 (-5), C16 (-5).
  To fix: Each deviation is a limitation: say how it bears on the result.

P5. The lab record flags the test: code changed after plan.
  Check: plan_flags (group: plan); costs up to 5 points.
  Lowers: C24 (-5), C25 (-5), C26 (-5).
  To fix: Rerun the test as planned, or explain the flag in a limitation.

P6. The plan's time is anchored by a git push only.
  Check: plan_anchor (group: plan); costs up to 3 points.
  Lowers: C1 (-3), C2 (-3), C3 (-3), C4 (-3), C5 (-3), C16 (-3), C24 (-3), C25 (-3), C26 (-3).
  To fix: Anchor plans with the platform, a timestamp authority (RFC 3161) or a registry.

P7. Assumption C13 is not checked: The numpy function per_lag_max() returns the same largest eigenvalue modulus as smoothEigensCpp() of smooth 4.6.0 (replaced in commit 4a44c1c) for models with a constant measurement vector and without adaptive regressors.
  Check: unchecked_assumption (group: open); costs up to 3 points.
  Lowers: C1 (-3), C2 (-3).
  Concerns: C13.
  To fix: Test the assumption, or analyse how sensitive the claim is to it.

P8. Limitation L1 (reduces transferability, mitigation partial): The 3042 ETS(A,N,A) models of the planned test of the per-lag check form the same fixed grid as exploratory run RN3, whose result prompted the hypothesis; only the 200 GUM models of that test were new data.
  Check: limitation (group: open); costs up to 1 points.
  Lowers: C1 (-1).
  Concerns: L1.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P9. Limitation L12 (reduces transferability, not mitigated): The PBH reference is not exact for a repeated unit root: the checker P4 found a model whose cancelled MA polynomial keeps a double root at -1, which the reference accepted and the cancellation and an exact gcd rejected. The random models of the planned tests have no such root.
  Check: limitation (group: open); costs up to 2 points.
  Lowers: C24 (-2), C25 (-2).
  Concerns: L12.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P10. Limitation L3 (reduces transferability, not mitigated): The random model sets (persistence ranges, the probabilities of zero persistence and of a constant, the standard deviations of the GUM matrices) were chosen by the agent and not drawn from models estimated on data.
  Check: limitation (group: open); costs up to 1 points.
  Lowers: C2 (-1), C3 (-1), C4 (-1), C5 (-1), C16 (-1).
  Concerns: L3.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P11. Limitation L5 (reduces transferability, not mitigated): The plans of the tests behind the step-down and bisection claims stated MA polynomial degrees up to 366; the generator code named in the plans, run unchanged, produced degrees up to 535 before cancellation.
  Check: limitation (group: open); costs up to 1 points.
  Lowers: C4 (-1), C5 (-1), C16 (-1).
  Concerns: L5.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P12. Limitation L6 (reduces transferability, mitigation partial): The recursion of the counterexample to the monograph's condition was run for one parameter pair, with the initial states set to one and no data.
  Check: limitation (group: open); costs up to 1 points.
  Lowers: C22 (-1).
  Concerns: L6.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P13. Limitation L8 (reduces transferability, not mitigated): For GUM models with structured parameters, such as a state with |F_ii| > 1 and zero persistence, theta and phi can share a factor with a root in |B| <= 1 that is not cyclotomic; the check keeps it and rejects the model although its observation weights decay, because the initial state of that mode has a growing effect.
  Check: limitation (group: open); costs up to 1 points.
  Lowers: C4 (-1), C16 (-1).
  Concerns: L8.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P14. Assumption C14 is not checked: The [[D5:PBH reference]] with relative rank tolerance 1e-7 classifies every eigenvalue of modulus at least 1 of the [[D2:expanded discount matrix]] of the tested models correctly as both reachable and observable or not.
  Check: unchecked_assumption (group: open); costs up to 3 points.
  Lowers: C1 (-1), C2 (-1), C3 (-3), C4 (-1), C16 (-1), C10 (-3), C11 (-3).
  Concerns: C14.
  To fix: Test the assumption, or analyse how sensitive the claim is to it.

P15. Assumption C19 is not checked: In additive ETS models, and in GUM models with an identity transition or with transition, persistence and measurement in general position, every factor shared by $\theta(B)$ and $\phi(B)$ with a root in $|B| \le 1$ is a product of cyclotomic polynomials $\Phi_n(B)$ with $n$ dividing a lag of the model.
  Check: unchecked_assumption (group: open); costs up to 3 points.
  Lowers: C4 (-3), C16 (-3).
  Concerns: C19.
  To fix: Test the assumption, or analyse how sensitive the claim is to it.

P16. Limitation L7 (reduces precision, not mitigated): The fit timings come from one machine, seven repeats per fit, with a run-to-run variation of about 10% between benchmark runs of the same code.
  Check: limitation (group: open); costs up to 5 points.
  Lowers: C23 (-5).
  Concerns: L7.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.

P17. Limitation L9 (reduces precision, not mitigated): Estimates with bounds="admissible" change for ETS+ARIMA models, whose admissible region changes, and the likelihood of such models can have several local optima: on ETS(A,N,A)+ARIMA(1,0,1) on AirPassengers the fit with the check of the whole model reached a lower log-likelihood than the fit with the check of the parts apart.
  Check: limitation (group: open); costs up to 5 points.
  Lowers: C27 (-5).
  Concerns: L9.
  To fix: Mitigate it with evidence, or narrow the claim's scope so that it no longer applies.
