Module versioned 

Shared versioned-symbol/namespace resolution service.

This is the single implementation used by every execution tier — the tree-walking interpreter, the IR interpreter, JIT-compiled code (via the rt_load_global* runtime bridges), and AOT binaries.

Model

Resolving ns/name@commit means: ensure the versioned namespace "ns@commit" is loaded (lazily, from an embedded builtin source or from git history), then perform a plain lookup_in_ns("ns@commit", name). Versioned namespaces are immutable once loaded, so a resolved value never changes for the lifetime of the process.

Native (Rust-backed) functions

Native functions registered via cljrs-interop::Registry have no Clojure source to fetch, and the binary is a single unit at runtime — we can’t “go back in time” to a previous compiled implementation. The current contract is: versioned lookups of a native symbol resolve to the HEAD (current) implementation regardless of the requested commit (see native_head_fallback).

Functions

base_ns_name

Strip a trailing @<commit> suffix from a namespace name, returning the base namespace. "my.lib@abc1234" → "my.lib"; names without a valid commit-hash suffix are returned unchanged.

ensure_versioned_ns_loaded

Ensure the versioned namespace "<base_ns>@<commit>" is loaded, returning its name.

pin_if_available

Pin base_ns@commit if any source for it is locatable, returning whether it was loaded.

resolve_versioned_value

Resolve the value of name pinned at commit.
