+//! indexing still reported success.
+//!
+//! It drives the real `DocStore`: real RocksDB keys, real embeddings, real
+//! HNSW search, and a reopen to confirm what survived on disk.
+//!
+//! Needs a local model2vec model directory, which is also what the
+//! `--embedding-model static` server path uses. Point `CODEGRAPH_STATIC_MODEL`
+//! at one, or have the default `~/.codegraph/static_models/jina-code-static-256`
+//! in place. The test skips (with a message) when no model is available rather
+//! than failing, since the model is not vendored in the repo.

+//! link against. Every target that links ONNX Runtime - the binary and the
+//! test executables, which do not include `main.rs` - has to supply one.
+//!
+//! The storage must be WRITABLE. It was previously `pub static ...: u8 = 0`,
+//! which lands in .rodata, under a comment claiming "on newer glibc the real
+//! symbol shadows this at runtime" - the opposite of how ELF resolves it. A
+//! definition in the executable takes precedence over the one in libc, and on
+//! aarch64 this symbol is also emitted into .dynsym, so glibc bound its own
+//! startup write of the flag to the read-only byte and took SIGSEGV before
+//! `main()`: every invocation died, including `--version` and `--help`
+//! (issue #15). x86_64 escaped only because the symbol is not dynamically
+//! exported there, so glibc kept using its own copy.
+//!
+//! glibc owns the value: it sets the flag at startup and clears it when a
+//! thread is created. We only supply the storage, and never read it. On a
+//! glibc too old to maintain it, the byte stays 0, which is the conservative
+//! "not single threaded" answer.
+//!
+//! Every definition of the symbol must use [`SingleThreaded`] so the writable
+//! storage cannot drift back to a plain `u8` in one target and not another.
