# @lssm-tech/lib.typescript-runtime

Owned runtime boundary for TypeScript compiler and AST access.

Consumers import AST helpers and source parsing from this package so TypeScript
upgrades have one repair point. The adapter isolates TypeScript 7's unstable
AST and asynchronous compiler APIs while preserving a stable asynchronous
parser contract for callers.

```ts
import {
	TypeScriptSourceParser,
	isVariableStatement,
} from "@lssm-tech/lib.typescript-runtime";
```


Call `close()` on long-lived parsers after use.

The explicit server-only `@lssm-tech/lib.typescript-runtime/docs-manifest-builder`
entry owns compiler-backed same-file DocBlock extraction and package manifest
generation. It exports `extractModuleDocData` and `buildPackageDocManifest` with
their existing asynchronous signatures and is the canonical import path. The
deprecated `@lssm-tech/lib.contracts-spec/docs/manifest-builder` subpath
forwards the same function identities until the next major release of
`@lssm-tech/lib.contracts-spec` removes it; new code imports this entry. This
entry rejects browser resolution and is not reexported by the root AST adapter.
Manifest and DocBlock types remain owned by surface-runtime and
contracts-spec-core, respectively.

`buildPackageDocManifest({ followReexports: true, ... })` additionally follows
static value reexports to canonical same-file DocBlocks. The option is additive
and defaults to `false`; existing callers keep their source-root-only behavior.
The compatibility package's `docs:manifest` producer imports this entry directly
and enables it so moving a contract into its canonical owner does not remove its
documentation. Traversal does not execute source modules or scan private sibling
files. Named aliases, cycles, and explicit export precedence are respected;
ambiguous documentation bindings, duplicate identifiers/routes, and missing
references fail validation.
DocBlock identifiers and payloads are preserved, while `sourceModule` identifies
the canonical package and source file for documentation outside the input root.

Each parser owns an isolated temporary workspace and native TypeScript session.
On Windows, the adapter uses the compiler client's supported stdio transport;
other platforms retain Unix sockets. This avoids Windows named-pipe readiness
and naming races without changing the asynchronous parser API or snapshot
semantics. The matching native TypeScript executable must be installed.

The root build targets Node-compatible server execution (including Bun). It
requires filesystem, process, or native compiler facilities and does not advertise
a browser export condition. Browser applications should use the relevant
browser-safe contracts or UI entry points instead of importing this server root.
