This PR installs the current generated git hooks and CI workflow of the ResearchHarness, commit 4e4b534. Two changes reach this repository.

The downgrade job resolves the root and test projects together

.github/workflows/CI.yml (ResearchHarness #157): the Downgrade job runs julia-downgrade-compat with projects: ., test. It resolves Project.toml and test/Project.toml into one manifest, at their lower bounds, and forcedeps checks the lower bounds of both.

Before, it resolved the root project alone, so each indirect dependency came in at its newest version, and the test run, which keeps that manifest, could not add a test-only dependency that caps it. Two forms of this failure appear across these packages: DocStringExtensions 0.10.2 against Documenter 1.19, and CEnum 1.0.0 against CairoMakie or Metal.

The job stays advisory, and the required checks do not change. A lower bound in test/Project.toml that cannot be reached now turns the job red, with forcedeps check failed: Some test dependencies did not resolve to their lower bounds. Such a bound is fixed on this branch before the merge.

The git hooks take the fixes of the hook review

.githooks/pre-commit.jl and .githooks/pre-push.jl (ResearchHarness #156):

• A package name that is not a Julia identifier is refused with one line, before any code is built from it.
• A Project.toml is a package only with both a name and a uuid; otherwise pre-commit runs no load test, and pre-push runs test/runtests.jl.
• An interrupted push waits until the suite's process group is gone, and kills it at the grace time.
• A failed load report starts at its first ERROR: line, and the error refusals print the location line.
• The staged paths reach fatou lint after --, and a fatou failure with no finding line is reported as a failure of fatou; the lint stage stays advisory.

Files

The six files are byte-identical to the ResearchHarness at 4e4b534, as harness githooks --apply and harness workflows --apply install them: CI.yml, .githooks/pre-commit, pre-commit.jl, pre-push, pre-push.jl and test-layout.jl. Only pre-commit and pre-push are executable. Files that already match do not appear in the diff. No package source changes.

Lower bounds for the merged downgrade check

The merged resolve could not reach two floors in test/Project.toml. Both are raised; the package's own [compat] does not change.

• GeometricBrackets = "0.2", from "0.1.1, 0.2". The root floor GeometricEquations = "0.21.5" requires GeometricBase 0.15, and GeometricBrackets 0.1.1 requires GeometricBase 0.14, so the resolve took 0.2.0, the first release on GeometricBase 0.15.
• GeometricIntegrators = "0.18.6", from "0.18.5". GeometricIntegrators 0.18.5 requires GeometricBase 0.14, so the resolve took 0.18.6, the first release on GeometricBase 0.15.

With these floors the downgrade resolve passes, and the full test suite passes at the floors on Julia 1.12.7. CHANGELOG.md has the entry under [Unreleased]. No other fix was needed.

Walkthrough

The pull request updates pre-commit and pre-push hook validation, diagnostics, and process cleanup. It also changes test dependency compatibility floors and configures the downgrade workflow to resolve lower bounds for both the root and test projects.

Changes: Julia hook updates

Layer / File(s)	Summary
Project validation and load diagnostics .githooks/pre-commit.jl, .githooks/pre-push.jl	Both hooks require a project name and UUID and validate the name as a Julia identifier. Error messages use headlines, and load failures show up to 20 lines starting at the first ERROR: line when present.
Pre-commit formatting and lint reporting .githooks/pre-commit.jl	Formatting errors and parse failures use headlines. Fatou receives staged paths after --; nonzero exits are classified by matching finding lines, or reported as Fatou failures when none match.
Hook process cleanup .githooks/pre-commit.jl, .githooks/pre-push.jl	The pre-commit timeout path uses monotonic timing and closes its SIGKILL timer. The pre-push test runner defers interrupts during startup and waits for both the process and process group to stop.

Test dependency compatibility

Layer / File(s)	Summary
Test dependency floors and downgrade resolution test/Project.toml, CHANGELOG.md, .github/workflows/CI.yml	The test compatibility floors for GeometricBrackets and GeometricIntegrators change. The downgrade workflow resolves lower bounds for the root and test projects together, and the changelog records the test-only floor changes.

• observed — test (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in CHANGELOG.md: The Unreleased notes add test-only compat floor changes for GeometricBrackets ("0.1.1, 0.2" to "0.2") and GeometricIntegrators ("0.18.5" to "0.18.6"). They describe the GeometricBase version conflict at the prior floors and state that the package’s own compat is unchanged.
• observed — Modified behavior in test/Project.toml: The GeometricBrackets compatibility entry now allows 0.2 only, excluding 0.1.1; the GeometricIntegrators minimum compatible version changes from 0.18.5 to 0.18.6.
• observed — Modified behavior in .github/workflows/CI.yml: The comments now describe resolving direct dependency lower bounds for both the root and test projects together, including the shared-manifest behavior and the failure when test/Project.toml is missing. They replace documentation that said only root-project dependencies were floor-tested.
• observed — Modified behavior in .github/workflows/CI.yml: The downgrade step now passes projects: ., test, so the action resolves the root and test projects together; previously this option was unset.

Minor · Functional Correctness · Quick win

Reject a named project without a UUID.

When Project.toml contains name but no uuid, package_name() returns nothing. A push to main or master can therefore select the test-only test/runtests.jl path under the root environment instead of rejecting the incomplete package metadata. Return nothing only when the project has no name; reject a named project that has no uuid.

Suggested fix

- The `name` of `Project.toml` in the current directory, of any type, when the file has both a
- `name` and a `uuid`; `nothing` when it has no file, no `name` or no `uuid`, which is no package.
+ The `name` of `Project.toml` in the current directory, of any type, when the file has both a
+ `name` and a `uuid`; `nothing` when it has no file or no `name`, which is a test-only project.
+ Throws `ArgumentError` when it has a `name` but no `uuid`.
 Throws `TOML.ParserError` for a `Project.toml` that does not parse.

.githooks/pre-commit.jl:324-326
Minor · Functional Correctness · Quick win

Match the load-error headline instead of any ERROR: substring.

When a package prints a line containing ERROR: before Julia reports ERROR: LoadError, the current search starts the 20-line window at the package output. The actual load failure and its location can then be omitted. Anchoring only ERROR: is not sufficient because package output can also begin with that text.

Suggested fix

-    start = something(findfirst(l -> occursin("ERROR:", l), lines), 1)
+    start = something(findfirst(l -> occursin(r"^\s*ERROR:\s+LoadError\b", l), lines), 1)
