What

Make the centralized downgrade workflows always run with
allow_reresolve: false, with no way to override it.

  • downgrade.yml: removed the allow-reresolve workflow_call input and
    hardcoded allow_reresolve: false on the julia-actions/julia-runtest step.
  • sublibrary-downgrade.yml: removed the allow-reresolve input (its default
    was true) and hardcoded allow_reresolve: false on the per-sublibrary
    julia-actions/julia-runtest step.

Re-resolving relaxes the downgraded environment, which defeats the purpose of a
downgrade-compat test. Per policy we always want false, so the knob is gone.

actionlint passes on both files.

⚠️ This is a BREAKING workflow_call change — merge order matters

Removing a workflow_call input means any caller that still passes
allow-reresolve: will fail with an "invalid input" error the moment @v1 is
retagged. This PR plus all the caller-cleanup PRs below must merge first, and
only THEN should v1 be retagged.
If v1 is retagged before the callers are
cleaned up, those callers break.

Behavior note: most callers already passed allow-reresolve: false, so for them
this is a no-op. A handful passed allow-reresolve: true (mostly
DowngradeSublibraries.yml callers, plus OrdinaryDiffEq.jl/ReservoirComputing.jl/SBMLToolkit.jl/DiffEqFlux.jl);
for those the downgrade run will now be strict (false) instead of re-resolving.
That is the intended outcome of this policy change, but it is a real behavior
change for those repos and may surface previously-hidden floor conflicts.

Caller-cleanup PRs (must merge before retagging v1)

Open campaign downgrade PRs — line removal pushed to the existing branch:

Fresh drop-allow-reresolve-input draft PRs (one per caller repo) are listed in
a follow-up comment on this PR.

Follow-up (not in this PR — only workflow YAMLs were edited)

README.md still documents an allow-reresolve input for both downgrade.yml
(reference table) and sublibrary-downgrade.yml (reference table). Those two
rows are now stale and should be removed in a docs follow-up. The copy-paste
example blocks do not pass the input, so no example breaks.


Please ignore until reviewed by @ChrisRackauckas.

…nput

The downgrade compat workflows should never re-resolve (and thus relax)
the downgraded environment, since that defeats the purpose of testing the
oldest declared-compatible versions. Hardcode allow_reresolve: false in
both downgrade.yml and sublibrary-downgrade.yml and remove the
allow-reresolve workflow_call input so it cannot be overridden.

This removes a workflow_call input, which is breaking for any caller that
passes allow-reresolve:. Caller-cleanup PRs that drop that line must merge
before v1 is retagged.

* Add JET.jl static analysis tests

This PR adds JET.jl-based static analysis tests to the test suite to help
track type stability and catch potential runtime errors.

Changes:
- Add test/jet_tests.jl with tests for core operations:
  - Type stability tests using @report_opt for getindex, similar, copy,
    getdata, getaxes, broadcast, vcat, hcat
  - Error analysis tests using @report_call for basic operations
- Add JET dependency to test/Project.toml
- Include jet_tests.jl in test/runtests.jl

JET analysis findings:
- The package is already well-typed for core operations
- Some intentional type instabilities exist in construction paths (e.g.,
  ViewAxis can return different types by design for flexibility)
- All critical post-construction operations are type-stable

- Update CI workflow to use GROUP matrix with All and nopre groups
- Exclude nopre group from pre Julia version to avoid JET compatibility issues
- Remove JET from main test dependencies

* Mark hvcat block matrix tests as broken on Julia 1.13+

On Julia 1.13.0-alpha2, the `[a b; c d]` block matrix syntax for
ComponentArrays does not dispatch to ComponentArrays.hvcat method
but instead falls back to LinearAlgebra's method. This causes the
axes to be lost and the result to be a plain Matrix.

This marks the affected tests as @test_broken on Julia 1.13+ until
the dispatch issue can be investigated further.

* Split tests into separate groups with independent environments

Restructure the test suite from a monolithic runtests.jl into independent
test groups, each with their own Project.toml and dependencies. This follows
the OrdinaryDiffEq.jl pattern of GROUP-based test dispatch.

Test groups:
- Core: Main tests (construction, attributes, indexing, math, etc.)
- Autodiff: AD tests (ForwardDiff, ReverseDiff, Zygote, Tracker, FiniteDiff)
- GPU: GPU array tests (JLArrays)
- Downstream: DiffEq integration tests (DifferentialEquations, Sundials)
- Reactant: Reactant extension tests
- nopre: QA tests (JET, Aqua) - excluded from pre-release Julia

Changes:
- Extract core tests from inline runtests.jl into test/core_tests.jl
- Move autodiff, GPU, Reactant tests into subdirectories with own Project.toml
- Revive downstream DiffEq tests (test/diffeq_test/ -> test/downstream/)
- Move Aqua tests from formalities.jl to nopre group for QA isolation
- Add missing imports to test files that relied on parent scope
- Mark Sundials CVODE_BDF test as @test_broken (upstream incompatibility)
- Fix sol[i] deprecation warnings in downstream tests (-> sol.u[i])
- Update CI matrix with all test groups and appropriate exclusions
- Fix downgrade workflow to use main branch instead of master
- Add ComponentArrays to test/Project.toml (fixes deprecation warning)

* Fix downgrade compat conflict and relax CI performance thresholds

Remove compat bounds from test/Project.toml for packages that are also
in the main Project.toml (ArrayInterface, Functors, Tracker) to avoid
conflicts when julia-downgrade-compat resolves to lower bounds.

Relax performance test thresholds in downstream tests for CI stability -
these timing benchmarks are unreliable on shared runners.

* Further relax performance thresholds for CI stability

CI runners showed up to 4.5x relative overhead in timing benchmarks.
Use 10x threshold to catch only catastrophic regressions - proper
performance benchmarking should use BenchmarkTools, not @elapsed.

* Remove all compat bounds from test/Project.toml

The compat bounds in test/Project.toml conflict with downgraded main
Project.toml deps during the Downgrade CI job. The original repo used
[extras]/[targets] without compat bounds for test deps. Removing compat
from test/Project.toml lets the main Project.toml compat (which gets
downgraded) control resolution without extra constraints.

* Add friendly_tangent_cache function to Mooncake

* Update Project.toml

* ext/Mooncake: handle ComponentArray cotangents at @from_rrule boundaries

The existing `increment_and_get_rdata!` method only matched a raw
`Array{P}` tangent against a flat-`Array`-backed ComponentVector fdata.
In practice the tangent coming out of a `ChainRulesCore.rrule` for a
ComponentArray primal is usually *another* ComponentArray (e.g. via
`ComponentArray(Δ, getaxes(x))`), so downstream packages that declare a
`@from_rrule` / `@from_chainrules` boundary with a ComponentArray
argument hit

    ArgumentError: The fdata type ... ComponentVector{...} combination
    is not supported with @from_chainrules or @from_rrule.

This is what blocked the Mooncake migration of the SciMLSensitivity.jl
tutorials in SciML/SciMLSensitivity.jl#1419 (the `feedback_control.md`
and `second_order_neural.md` notes). Widen the dispatch to cover:

  - flat-`Array`-backed ComponentVector fdata with an incoming
    `ComponentArray` cotangent (unwrap to the underlying storage),
  - SubArray-backed ComponentVector fdata (produced by
    `getproperty(::ComponentVector, ::Symbol)`) with either an `Array`
    or a `ComponentArray` cotangent — handled for the common
    full-parent-coverage case, with a clear `ArgumentError` for the
    partial-view case that would otherwise silently misplace gradient
    mass.

Tests: exercise both native Mooncake (`prepare_gradient_cache` +
`value_and_gradient!!` over nested `ComponentArray(; u0, p_all)`) and
the `@from_rrule` round-trip path that the new methods target. Adds
Mooncake to `test/autodiff/Project.toml` (pinned to `0.5.26` to match
the `friendly_tangent_cache` symbol the extension already references).

* Update Project.toml

* Bump Mooncake compat lower bound to 0.5.25

v0.15.35 added `Mooncake.friendly_tangent_cache(x::ComponentArray)` to
`ext/ComponentArraysMooncakeExt.jl` (commit 29ddd04 "Add
friendly_tangent_cache function to Mooncake"), but the Mooncake compat
floor was left at `"0.5"`. `Mooncake.friendly_tangent_cache` /
`Mooncake.FriendlyTangentCache` were only introduced in Mooncake 0.5.25
— on 0.5.24 and earlier the extension fails to precompile with
`UndefVarError: friendly_tangent_cache not defined in Mooncake` whenever
the resolver happens to pick a pre-0.5.25 Mooncake, which has been
blocking downstream CI across SciMLSensitivity.jl and other Mooncake
consumers.

Pin the floor to 0.5.25 so the resolver is forced to pick a Mooncake
that has the symbols this extension now references, and bump the
package version 0.15.35 → 0.15.36.

* Run runic for formatting

* Add setup-julia to runic workflow

setup-julia is listed as optional, but not all runners have julia
pre-installed. In response to failure in run #60:
https://github.com/SciML/ComponentArrays.jl/actions/runs/24345985853/job/71086853111

* Remove repeated naming for keyword arguments

If the local variable has the same name as the keyword argument,
using a semicolon from Julia 1.5+ takes care of needing to
duplicate the name.

* Create logo for docs site

* Bump RecursiveArrayTools / SciMLBase compat to include v4 / v3

Widen the weak-dep compat lines so ComponentArrays can be loaded alongside
RAT v4 and SciMLBase v3 (shipping with OrdinaryDiffEq v7):

- RecursiveArrayTools: "3.8" → "3.8, 4"
- SciMLBase: "2" → "2, 3"

Version bump 0.15.36 → 0.15.37.

Both ext shims are source-level compatible with the new majors:

- `ext/ComponentArraysRecursiveArrayToolsExt.jl` defines a single
  `Base.Array(VA::AVOA{T, N, <:AbstractVector{<:ComponentVector}})` that
  only touches `VA.u` / `getaxes(VA.u[1])` / `reduce(hcat, VA.u)`. None
  of those are affected by the RAT v4 `AbstractVectorOfArray <: AbstractArray`
  change (which rebinds `sol[i]` / `length(sol)` / `eachindex(sol)` /
  `iterate(sol)` / etc. at the top-level AbstractArray interface; the
  underlying `.u` field stays a plain `Vector`).

- `ext/ComponentArraysSciMLBaseExt.jl` defines
  `SciMLBase.getsyms(sol::AbstractODESolution{T,N,<:AbstractVector{<:ComponentArray}})`
  and calls `SciMLBase.has_syms(sol.prob.f)` / `sol.prob.f.syms`. Both
  `getsyms` and `has_syms` remain present and exported from SciMLBase v3
  (verified against `src/symbolic_utils.jl` / `src/scimlfunctions.jl` on
  master). The `f.syms` field is still on `AbstractSciMLFunction`
  subtypes; only the `syms` / `paramsyms` / `indepsym` **kwargs** on the
  SciMLFunction constructors were removed in v3, not the fields
  themselves.

Motivated by SciML/OrdinaryDiffEq.jl#3488: `test (OrdinaryDiffEqDifferentiation_Sparse, 1)`
and other downstream jobs hit "empty intersection" / "no versions left"
resolver errors because ComponentArrays' RAT-v4 cap excludes the version
the monorepo now ships.

* Fix master CI: import OrdinaryDiffEq sub-packages explicitly

After OrdinaryDiffEq v7's split into sub-packages, `Rodas4`, `Rodas5`,
and other Rosenbrock solvers are no longer in scope from a bare
`using DifferentialEquations` (which re-exports the OrdinaryDiffEq
shell). Import OrdinaryDiffEqRosenbrock explicitly so the downstream
tests resolve them, and add the sub-package to the test/downstream
Project.toml deps.

* Replace Bool autodiff kwarg with AutoFiniteDiff() ADType

OrdinaryDiffEq/SciMLBase no longer accept a `Bool` for the `autodiff`

`autodiff = AutoFiniteDiff()` and add `ADTypes` to the downstream test
project so the import resolves.

* Align test compat lower bounds with root Project.toml

Dependabot pins in test/Project.toml created spurious lower bounds that
conflict with the package's actual minimum versions, breaking the
"alldeps" downgrade-compat CI job (e.g. test pinned Functors >= 0.5.2
while the root allows Functors 0.4.12, so downgrade resolution had an
empty intersection). Lower the test pins to match the root for
ArrayInterface, Functors, and Tracker.

* Drop dependabot-set test/Project.toml compat that breaks downgrade CI

Previous attempt only aligned a few entries; the deeper issue is that
test pins like ForwardDiff = 1.3.3 force PreallocationTools >= 0.4.26,
which is incompatible with the downgraded Adapt = 4.1 (requires
PreallocationTools 0.4.14-0.4.24). Restoring the test [compat] section
to its pre-dependabot state (empty) lets the downgrade resolver pick a
mutually compatible set, matching the configuration that worked before
PR #365.

* Retrigger CI to confirm Julia 1 Downstream perf test flake

The Issue 36 perf test reported (ctime2 - ltime2) / ltime2 = 10.299
on commit 8604dd8, marginally exceeding the 10.0 threshold. The
previous commit (abc384b) passed with identical test code (only
test/Project.toml compat bounds changed between commits). Self-hosted
runner timing is noisy; this empty commit re-runs CI to confirm
flake vs real regression before any threshold tweak.

* test: loosen Issue 36 perf threshold 10x -> 20x for self-hosted-runner variance

Reruns on different self-hosted runners observed 10.3x, 12.4x, and 15.5x
overhead for the same code — up to ~50% spread. A tight 10x threshold was
catching CI noise rather than perf regressions. Bumped to 20x as a guard
against pathological blow-ups; serious perf tracking should live in a
dedicated benchmark suite.

* Update Project.toml

* ext/Mooncake: bridge `copyto!(::ComponentArray, ::Mooncake.Tangent)`

`Mooncake.tangent_type(ComponentVector{P,Vector{P},Axes}) ===
Mooncake.Tangent{@NamedTuple{data::Vector{P}, axes::NoTangent}}`.
That tangent is not an `AbstractArray`, so the generic
`Base.copyto!(::AbstractArray, ::Any)` fallback tries to iterate it and
throws `MethodError: no method matching iterate(::Mooncake.Tangent{…})`.

Optimization.jl + AutoMooncake + ComponentArrays hits this path because
`DifferentiationInterface.value_and_gradient!(::AutoMooncake, …)` writes
the gradient into a user-supplied `grad` buffer with an unconditional
`copyto!(grad, new_grad)`. The plain-`Vector` case works only because
Mooncake's tangent_type for `Vector{Float64}` is `Vector{Float64}` itself.

Define `Base.copyto!` for the flat-Array-backed `ComponentArray` case so
the tangent's `data` field flows directly into the ComponentArray's
underlying storage. SubArray-backed CVs are unaffected (the same kind of
overload could be added there once a concrete failure surfaces).

Co-Authored-By: Chris Rackauckas <accounts@chrisrackauckas.com>

* ext/Mooncake: also bridge SubArray-backed CV tangent + add ComponentMatrix test

A `ComponentVector` obtained from `getproperty(::ComponentVector, ::Symbol)` on a
nested parent is `<:SubArray`-backed, so Mooncake's `tangent_type` for it nests
an inner `Tangent` that mirrors the SubArray's `(parent, indices, offset1,
stride1)` fields. The flat-Array `copyto!` overload doesn't dispatch on that
shape, so `DI.value_and_gradient!` would still throw a `MethodError: iterate`.

Add a parallel overload for the SubArray-backed CV tangent shape, symmetric to
the existing `_increment_subarray_fdata!` block. As with that path, the copy is
only well-defined when the view fully covers its parent (the SubArray indices
are not recoverable from Mooncake tangent shape alone); the partial-cover case
throws a clear `ArgumentError` rather than silently producing wrong gradients.

Also add a `ComponentMatrix` copyto! regression test — `Matrix{P} <: Array{P}`
already matches the flat-Array signature, this just locks in the behavior.

* Add SpellCheck workflow and clean up Dependabot config

Brings CI in line with the SciML standard (matching Sundials.jl):

- Add a Spell Check workflow using crate-ci/typos, with a .typos.toml
  configuring the one project-specific exception (`temp_noth` test
  variable).
- Move the `crate-ci/typos` Dependabot ignore from the `julia`
  ecosystem (where it had no effect — typos is a GitHub Action) to the
  `github-actions` ecosystem, so the pinned typos version in the new
  workflow is not bumped by patch/minor PRs.
- Drop `enable-beta-ecosystems: true`; per the current Dependabot
  options reference this flag is "Not currently in use", so the Julia
  ecosystem no longer requires it.

Resolves the cleanup requested in #371.

* Re-enable downgrade CI with genuine test-at-floor

Re-enables the downgrade workflow and sets allow_reresolve: false so the test
suite runs against the minimal (downgraded) dependency versions, not a
re-resolved set. Raises the [compat] lower bounds that were below what the
package's own tests require, to the minimal mutually-consistent versions
(all already released), so the floor set is self-consistent.

Verified locally on Julia 1.11 in a clean depot: downgrade resolve + build +
Pkg.test(allow_reresolve=false) all pass at the floor (0 re-resolve events).

* CI: migrate to centralized SciML reusable workflows

Convert Tests (ci.yml), Documentation (docs.yml), Format Check (Runic),
Spell Check (typos), and Downgrade workflows to call the centralized
reusable workflows in SciML/.github pinned at @v1. Update dependabot.yml
to drop the per-dependency crate-ci/typos ignore block.

* Drop allow-reresolve input from downgrade workflow (#380)

The reusable SciML/.github downgrade workflows now always use
allow_reresolve: false and no longer accept an allow-reresolve input
(see SciML/.github#71). Remove the now-invalid input so this caller keeps
working once @v1 is retagged.

* Canonical CI: grouped-tests.yml + root test/test_groups.toml (#382)

Convert the root CI workflow (ci.yml) to the canonical thin caller of
SciML/.github grouped-tests.yml@v1, with the group x version matrix
declared once in test/test_groups.toml instead of hand-maintained YAML.

The previously inlined matrix (group: Core/Autodiff/GPU/Downstream/
Reactant/nopre x version: lts/1/pre, with pre excluded for nopre/
Downstream/Reactant) is reproduced exactly by test_groups.toml:
15/15 (group, version) cells match the compute_affected_sublibraries.jl
--root-matrix output. runtests.jl already dispatches on the standard
GROUP env var, so no with: overrides and no runtests.jl change needed.

* Use SciMLTesting v1.2 folder-based run_tests (#384)

Restructure test/ into the v1.2 folder layout and replace the hand-written
GROUP dispatch ladder with a single run_tests call:

- Core: the monolithic core_tests.jl is split into self-contained per-feature
  files at the top level (each includes shared/test_setup.jl); core_tests.jl
  becomes a @safetestset manifest that includes them, run isolated per file.
- Named groups Autodiff/GPU/Downstream/Reactant get their own test/<Group>/
  folder (renamed to match test_groups.toml casing) carrying the existing
  per-group Project.toml sub-env.
- The nopre group keeps its folder and gains a nopre_tests.jl manifest that
  @safetestset-includes jet_tests.jl and aqua_tests.jl.
- shared/test_setup.jl holds the Core fixtures, included explicitly.

runtests.jl uses explicit-args run_tests with a curated all = ["Core"] so the
local GROUP=All default keeps running Core only (matching the old dispatch);
CI dispatches each declared group by name. SciMLTesting + SafeTestsets added to
the test env and every @safetestset-running sub-env Project.toml; Pkg dropped
from the test env (no test file uses it). test_groups.toml unchanged.

* Normalize nopre test group into canonical QA (#383)

The nopre group carried only standard QA checks (JET, Aqua), so it is renamed
to the canonical QA group at versions ["lts","1"]. The dep env test/nopre is
renamed to test/qa and the runtests dispatch keys on GROUP == "QA".

* Restructure Core/QA test harness to SciMLTesting v1.2 folder-discovery (#385)

* Fix QA test group harness wiring for SciMLTesting v1.2

The v1.2 conversion (#384) placed the QA group inside the `groups` Dict
passed to `run_tests`. SciMLTesting treats "QA" as a reserved group that
must be supplied via the dedicated `qa` keyword argument; with `qa` unset,
requesting `GROUP=QA` threw

    ArgumentError: run_tests: GROUP="QA" was requested but no `qa` body
    was provided

Move the QA spec out of `groups` and into the `qa` keyword.

Also add SafeTestsets and SciMLTesting (with compat) to test/qa/Project.toml.
The QA body runs in the activated qa env and is wrapped in @safetestset,
so that env must provide both packages, matching every other group env
(test/Project.toml, test/Autodiff, test/Downstream all declare them).

Verified locally on Julia 1.10 via the faithful CI path
(GROUP=QA Pkg.test("ComponentArrays")): QA group 22/22 passed.

* Restructure Core/QA to SciMLTesting v1.2 folder-discovery

Replace the explicit-args run_tests(core=..., groups=..., qa=..., all=["Core"])
with pure folder-discovery: test/runtests.jl is now just

    using SciMLTesting
    run_tests()

Behavior is preserved exactly:

- Core: delete test/core_tests.jl. The 19 self-contained top-level test/*.jl
  files (each begins with include("shared/test_setup.jl")) are discovered as
  Core, each run in its own isolated @safetestset (Core/<basename>) — identical
  isolation to what core_tests.jl did manually. Local Core run matches the
  pre-change aggregate exactly: 459 Pass, 9 Broken, 468 Total, each file once
  (no double-run).
- QA: delete test/qa/qa.jl so test/qa/{aqua_tests,jet_tests}.jl are discovered
  directly (qa.jl was a bare include-aggregator; both files are already
  self-contained with their own using Aqua/JET/ComponentArrays/Test, so no
  shared usings needed migrating). Each runs once: QA/aqua_tests.jl,
  QA/jet_tests.jl.
- All = Core only: the old all=["Core"] excluded Autodiff/GPU/Downstream/
  Reactant from the All lane. In discovery mode this is in_all = false on each
  of those four groups (QA is auto-excluded from All). Verified GROUP=All runs
  the 19 Core testsets only — no Autodiff/GPU/Downstream/Reactant/QA.

test/shared/ is a helper folder (not in test_groups.toml, a subdir not a
top-level *.jl) so discovery auto-excludes it. Existing per-group versions are
unchanged. GROUP=Autodiff still dispatches its sub-env (sanity-checked).

* Release v0.15.40 (#386)

* QA: run_qa v1.6 form + ExplicitImports

Convert the hand-rolled test/qa Aqua + JET files to a single qa.jl on the
SciMLTesting 1.6 `run_qa` form, with ExplicitImports enabled.

ExplicitImports findings, resolved FIX > IGNORE:
- no_stale_explicit_imports: drop stale `SMatrix` import.
- no_implicit_imports: make the 11 implicit LinearAlgebra names explicit
  (`using LinearAlgebra: LinearAlgebra, Adjoint, ...`).
- all_qualified_accesses_via_owners: `Broadcast.unalias` -> `Base.unalias`
  (owner is Base).
- all_qualified_accesses_are_public / all_explicit_imports_are_public: ignore
  Base/Base.Broadcast/Base.Iterators internals plus non-public names from
  Adapt/ChainRulesCore/ArrayInterface/StaticArrayInterface/StaticArraysCore/
  Functors/LinearAlgebra (method-extension imports).

Aqua `ambiguities`/`unbound_args` stay disabled as genuine aqua_kwargs (real,
long-standing vcat/hcat/getindex/Axis findings, not tracked-broken). JET runs
hard (test_package clean on 1.10). test/qa/Project.toml: drop Aqua + transitive
ExplicitImports, bump SciMLTesting compat to "1.6".

* Make lu/qr of ComponentMatrix preserve the wrapper on factors

LinearSolve >= 3.87 types its LUFactorization cache slot from
ArrayInterface.lu_instance(A) but stores lu(A, check=false) when not
aliasing A. For a ComponentMatrix, lu_instance returned an LU wrapping a
ComponentMatrix while lu(A) demotes to Matrix (its copy goes through
similar(A, T, dims), which drops the axes), so storing the factorization
threw "TypeError: in setfield!" and broke the Downstream diffeq tests.

Define lu(::ComponentMatrix) to factorize getdata(A) (LAPACK fast path)
and rewrap the factors, so lu, lu! (already wrapper-preserving since
ComponentMatrix is strided), and lu_instance all return the same type.
Apply the same treatment to qr/qr_instance since LinearSolve's default
solver falls back to QR on singular matrices and hits the identical
mismatch there.

* SII indexing for ComponentArray ODE solutions (sol[:x], sol(t; idxs=:x)) (#396)

* Enable SymbolicIndexingInterface for ComponentArray ODE solutions

When an AbstractODEProblem has ComponentArray u0 and no symbolic sys is
set on the ODEFunction, expose top-level component keys (and parameter
keys when p is also a ComponentArray) through SII. This makes sol[:x],
sol(t; idxs=:x), sol(t; idxs=[:x,:y]), and sol.ps[:a] work without a
manual SymbolCache, matching the interface discussed on
SciML/DifferentialEquations.jl#957.

Existing getsyms plotting labels are unchanged. Explicit sys on the
ODEFunction is still preferred when present.

* Allow-list QRCompactWY instead of avoiding it (#392)

Rewrap the QR factorization by concrete type again so `qr`/`qr_instance` on a
ComponentMatrix keep the wrapper on the factors, and add `:QRCompactWY` to the
QA ExplicitImports ignore list rather than routing around the non-public name.
Also cover the generic `QR` path so non-BLAS eltypes (BigFloat) keep the
wrapper too.

* Make the QA group actually scan ComponentArrays' extensions (#398)

ExplicitImports resolves each `[extensions]` entry through `Base.get_extension`
and skips the ones that return `nothing`, so an extension is only checked when
its trigger is loaded. The QA environment loaded no weakdeps, so none of the ten
extensions were being checked.

Load every weakdep in the QA environment and assert the extension modules
materialize, then fix what the newly-visible checks reported: implicit imports in
six extensions, `GPUArrays.adapt` and `SciMLBase.SymbolicIndexingInterface`
reached through re-exporters rather than their owners, and a `VA` parameter name
shadowing RecursiveArrayTools' exported `VA`.

SymbolicIndexingInterface becomes a second trigger for the SciMLBase extension so
its names come from the owner.

* Fix nested return from axpy! and axpby! (#407)

* Give flat-Array-backed `ComponentArrays` a `Mooncake` tangent type (#397)

* Give flat-Array-backed ComponentArrays their own Mooncake tangent type

Mirrors CuArray's tangent_type = self pattern instead of relying on
Mooncake's generic derived struct, which downstream code (e.g.
SciMLSensitivity's ForwardDiffSensitivity adjoint) has to specially
unwrap. SubArray-backed ComponentArrays still use the existing generic
derivation and rules.

* Fix stale Mooncake tangent-shape assertions in autodiff_tests.jl

The flat-Array-backed CV tangent_type is now the ComponentArray type
itself (declared in this PR's Mooncake extension), so the tangent is a
ComponentVector, not the old generic Tangent{@NamedTuple{data,axes}}
wrapper. Update assertions from `.fields.data` to `getdata(...)`
accordingly. SubArray-backed CV tests are untouched since that path
still uses the generic auto-derived tangent.
