This fixes a failure on the default branch's CI. The diagnosis and the evidence below come from the investigating agent's report; "confirmed by running" and "read in logs" are kept apart there.

Change

• test/qa/Project.toml: JET = "0.9, 0.10, 0.11" -> JET = "0.9, 0.10, 0.11, 0.12". One commit on local branch green/ExponentialUtilities.jl. Nothing else changed.

Commands

Before (master compat):

• GROUP=QA julia +release --project -e 'using Pkg; Pkg.test()' (Julia 1.13.2): FAIL at resolve: Unsatisfiable requirements detected for package JET ... restricted by julia compatibility requirements to versions: 0.12.0 - 0.12.3 or uninstalled — no versions left
• GROUP=QA julia +lts --project -e 'using Pkg; Pkg.test()' (Julia 1.10.12, JET 0.9.18): PASS, 24 pass, 2 broken (already marked @test_broken)

After (branch):

• GROUP=QA julia +release --project -e 'using Pkg; Pkg.test()' (JET 0.12.3): PASS, 28 pass, 2 broken (the same two)
• GROUP=QA julia +lts --project -e 'using Pkg; Pkg.test()' (JET 0.9.18): PASS, 24 pass, 2 broken (the same two)
• git diff | typos -: clean. No .jl files changed, so Runic was not needed.

JET reports fixed

None. JET 0.12.3 reported no problems on Julia 1.13.

Notes

• The gitignored root Manifest.toml that Pkg.test writes had to be deleted before switching between Julia 1.13 and 1.10. A 1.13-format manifest breaks resolution on 1.10. This is a local-run issue, not a CI issue.
• The 1.10 run prints a warning that also appears on master: could not import LinearAlgebra.diagview into ExponentialUtilities.
• Not run: Core, GPU and docs groups. The change touches only the QA environment.

🤖 Generated with Claude Code

Independent review (added by the fleet master)

Risk assessment

• Risk: low
• Blast radius: JET version resolution in test/qa/Project.toml; JET 0.12 may expose QA reports. No runtime source or public API changes.
• Evidence: gh pr diff shows 1 JET compat append(s) in test/qa/Project.toml; all existing bounds retained; no other changed lines, source edits, silencing, sources/path edits, or other dependency edits. gh pr checks: QA pending — no QA job reported yet; test discovery/workflows are queued or running. Local tests not run; PR body not read.
• Independent review: codex gpt-6.1-sol rated it low, high confidence in diff scope: every edit only appends JET 0.12 while retaining existing bounds; runtime compatibility is unverified while QA is pending.
• Merge: auto-merge candidate — focused compat-only change; require successful QA and required checks before merging
