调研方向

Start by tracing host-function registration, snapshot metadata persistence, and both persistent and in-memory restoration validation. Decide how the stable contract ID or versioned schema is represented and compared, then verify that contracted functions reject incompatible snapshots while functions without contracts retain name-only validation.

描述

lifecycle/needs-review
Problem

Hyperlight-JS snapshot compatibility currently validates only module and
function names.

Typed Rust callbacks are erased to a JSON bridge during registration, while
JavaScript callbacks are inherently dynamic. Hyperlight therefore sees only
the fixed CallHostJsFunction bridge signature and cannot verify that logical
functions such as database.query retain compatible argument and return
semantics.

Rust TypeId is process-local and type_name() is not a stable serialized
contract. Neither reliably describes Serde JSON representation.

Proposed solution

Allow host-function registration to include an explicit stable contract ID or
versioned schema, for example:

database.query: database.query/v1

Persist this identifier alongside each module/function name in snapshot
metadata and compare it during persistent and in-memory restoration.

Functions without a contract retain current name-only validation for backward
compatibility.
