Left open deliberately for the owner. Not blocked, not forgotten.

This is the one dependency update in the backlog that changes the emitted .d.ts of a package with ~293k downloads a month, and it cannot be proven safe by the checks this repo currently runs.

The reasoning:

• packages/type-plus declares peerDependencies: { "typescript": ">= 5.6.0" }. The catalog pins ~5.6.0, so today the declarations are emitted by the oldest compiler the package promises to support. That is the safe end of the range.
• Building with 5.9 emits declarations that a consumer on TypeScript 5.6 must still be able to parse. Nothing here tests that. test:type:54 / test:type:55 / test:type:latest compile the source on three compilers; none of them compiles the emitted .d.ts on the oldest supported one. For a library that is almost entirely type-level, that is the check that matters.
• For a normal library the risk is negligible. For this one the declarations essentially are the product.

What would make this mergeable, in rough order of effort:

1. Add a matrix entry that typechecks the built esm/index.d.ts with ts-5.6 and fails on any parse error, then bump the catalog. That closes the gap permanently, not just for this PR.
2. Or raise peerDependencies to >= 5.9.0 in the same change and treat it as breaking — which is available cheaply right now, since the repo is in changesets prerelease mode on the 8.0.0-beta.* line and latest is still 7.6.2.

Also worth noting while this is open: the type-test matrix runs 5.4 and 5.5, both below the >= 5.6.0 the package promises. The floor being tested and the floor being advertised do not currently agree.

Everything else in the dependency backlog has been landed or closed with a reason (#631 explains why none of it could merge itself). This one is a judgment call about a published artifact, so it stays with you.
