What changes and why

[compat] moves to GeometricOptimizers 0.9 and ReducedComplexityModeling 0.5:

package	before	after
GeometricOptimizers	"0.7, 0.8"	"0.9"
ReducedComplexityModeling	"0.3"	"0.5"
GeometricBase	"0.14.9, 0.15"	"0.15"
SimpleSolvers	"0.13.2, 0.14"	"0.14.2"
GeometricEquations	"0.21"	"0.21.5"
GeometricSolutions	"0.6.5"	"0.6.6"

The two main bounds move together. ReducedComplexityModeling 0.3 requires NeuralNetworkParameters 0.3, and GeometricOptimizers 0.9 requires NeuralNetworkParameters 0.5, so no environment holds both.

Four floors rise because of the General registry:

• Every GeometricOptimizers 0.9 release requires GeometricBase 0.15 and SimpleSolvers 0.14.2 - 0.14. The old floors of GeometricBase and SimpleSolvers can therefore not resolve beside it, and the Downgrade job fails on them.
• GeometricEquations 0.21.0–0.21.4 and GeometricSolutions 0.6.0–0.6.5 require GeometricBase 0.14. With GeometricBase at 0.15, their floors rise to 0.21.5 and 0.6.6.

The floor set resolves on Julia 1.12: GeometricBase 0.15.0, GeometricEquations 0.21.5, GeometricOptimizers 0.9.0, GeometricSolutions 0.6.6, ReducedComplexityModeling 0.5.0, RuntimeGeneratedFunctions 0.5.12, SimpleSolvers 0.14.2, Symbolics 7.0.0.

No source or test file changes. The package uses Optimizer, OptimizerState, BFGS and Backtracking from GeometricOptimizers, and TrainingData and IntrinsicSpace from ReducedComplexityModeling; the tests also use ObservableSpace. Both releases keep these names. The CHANGELOG [Unreleased] section gets one entry for the bounds and floors, and the Julia 1.12 floor entry now names GeometricOptimizers 0.9 and ReducedComplexityModeling 0.5 as its reason. No release.

Supersedes #35 and #37.

Test suite

A fresh resolve gives GeometricOptimizers v0.9.2, ReducedComplexityModeling v0.5.0 and NeuralNetworkParameters v0.5.4; the base resolves GeometricOptimizers v0.8.0 and ReducedComplexityModeling v0.3.1.

Pkg.test() passes 261 assertions on the branch, the same count as on the base: Aqua 9, Basis 30, Extended Bases 60, Training Data 15, Solvers 11, SINDy 12, Hamiltonian SINDy 37, RCM 38, Conformance 49. The last two commits of the branch change only CHANGELOG text.

Critic verdict: PASS

clause	evidence	verdict
1. [compat] reads GO "0.9" and RCM "0.5"; no other line changes unless the resolve needs it	only the two [compat] hunks at the judged head; the four floors that follow are the decisions below	met
2. fresh resolve shows GO 0.9.x and RCM 0.5.x, and Pkg.test() passes	GO v0.9.2, RCM v0.5.0, NNP v0.5.4; base GO v0.8.0, RCM v0.3.1; 261 = 261	met
3. no GradientOptimizer, MomentumOptimizer, AdamOptimizer or optimize_for_one_epoch!	git grep has no hits on the base or the branch	met
4. one [Unreleased] entry for the bounds; the Julia 1.12 sentence names GO 0.9 / RCM 0.5	confirmed against the registry	met
edge: RCM 0.5 call sites	the package uses only TrainingData, IntrinsicSpace, ObservableSpace	met
edge: default stays BFGS() with Backtracking()	unchanged	met

Mutant survival

The named mutant replaces the default algorithm = BFGS() of OptimizerSolver() with GradientMethod(). It survives the OPTIMIZER_ATOL tests at test/solvers.jl:34 and :42: the errors are 6.19e-8 and 5.47e-8 with GradientMethod(), against 2.78e-9 and 7.00e-9 with BFGS(), all below the tolerance 1e-6. The suite still catches the mutant at test/reducedcomplexitymodeling.jl:134.

Decisions taken without the user

• The floors that the new GeometricOptimizers bound makes unreachable rise with it: GeometricBase "0.15" and SimpleSolvers "0.14.2", because every GeometricOptimizers 0.9 release requires GeometricBase "0.15" and SimpleSolvers "0.14.2 - 0.14", so the Downgrade job cannot resolve the old floors. Clause 1's "no other [compat] line" does not cover these two; the CHANGELOG entry names them.
• GeometricEquations rises to "0.21.5" and GeometricSolutions to "0.6.6", because GeometricEquations 0.21.0–0.21.4 and GeometricSolutions 0.6.0–0.6.5 need GeometricBase 0.14, and the floor set then resolves on Julia 1.12.

Clause 1 as written ("no other [compat] line changes") is therefore not met: four more lines change, for the registry reasons above.

Pre-PR verification

• Fixed: nothing needed a fix. After the verifier ran, one CHANGELOG sentence with two colons was joined with "because"; this one-word change is the only text that the verifier has not read.
• Unresolved: none.
• Pre-existing: one [Unreleased] entry says test/Project.toml lists GeometricBase, GeometricEquations and Symbolics with the root's bounds. An earlier entry says they were removed, and the file agrees with the earlier one. This is a nit, and this branch did not cause it.
• Checked and clean:
  • Every new [compat] bound and every registry claim in the new CHANGELOG entry agrees with General.
  • The floor set is consistent with itself, and the test-only and docs-only bounds (GeometricIntegrators 0.18, GeometricProblems 0.8/0.9) still admit it.
  • The names the package imports still exist in GeometricOptimizers 0.9.2, and its re-export of solve, which two source comments describe, is still there.
  • No file other than CHANGELOG.md names an old bound.
  • Both changed files are NFC.
• Not checked: piracy, type stability and allocations, because no executable line changed. The Downgrade resolve was not run locally; CI runs it.
• Release: no bump needed. Nothing has been released, and the package stays at 0.1.0.

Review details

Systems and components

• observed — CHANGELOG.md (service) was modified; 1 changed file maps to changed impact.
• observed — Project.toml (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in CHANGELOG.md: The changelog changes the stated Julia minimum from 1.11 to 1.12 and updates the compatibility explanation to name GeometricOptimizers 0.9 and ReducedComplexityModeling 0.5 as requiring that version.
• observed — Modified behavior in CHANGELOG.md: The changelog replaces the prior dependency bounds with GeometricOptimizers 0.9 and ReducedComplexityModeling 0.5 only, explaining that their NeuralNetworkParameters requirements prevent the older versions from resolving together. It updates the associated minimums for GeometricBase and SimpleSolvers, then raises GeometricEquations and GeometricSolutions minimums to versions compatible with GeometricBase 0.15.
• observed — Modified behavior in CHANGELOG.md: The changelog updates the ReducedComplexityModeling dependency version from 0.3 to 0.5 and revises the compatibility history accordingly. It retains the statements that no names are re-exported or added and that the conversion between RCM TrainingData and package TrajectoryData is private.
• observed — Modified behavior in CHANGELOG.md: The changelog updates the minimum-version consequences: environments below the prior GeometricBase, SimpleSolvers, and RuntimeGeneratedFunctions floors cannot resolve the release, and the related dependency-bound entry raises GeometricBase, SimpleSolvers, and GeometricSolutions floors again.
