The analyzer normalizes its root with fs.realpathSync, which keeps a
Windows 8.3 short name such as RUNNER~1 in the runner's TEMP, while
TypeScript reports module-resolution results through
fs.realpathSync.native, which expands it. The guard compared the two
spellings, found the resolved lib/ declaration outside the workspace,
and let a missing alias through on Windows. It now canonicalizes the
root and every file with realpathSync.native and reports paths spelled
under the caller's root; the guard specs also run with the workspace
root spelled through a directory link.

rejectBuildOutputs caught a missing paths alias only when the package's
lib/types already existed. On a tree whose packages are not yet compiled,
as when host-typert runs beside host-src on a clean checkout, the import
resolved to nothing and checkDiagnostics: false hid it. The guard now also
fails when a face program cannot resolve an import of a workspace package,
found through its node_modules link, and names the paths entry derived
from the package's exports types condition.

Each of the 61 cases copied the fixture onto disk and ran a full analysis
whose four TypeScript programs reloaded the DOM library, @types/node, and
zod v4; about 22,000 file-system probes per analysis dominated on a
network filesystem. The spec now mocks the node:fs calls the analyzer
makes and the ts.sys host for an in-memory workspace, stubs zod and
@types/node except in the Emitter case that runs real zod, drops the DOM
library from the fixture, and shares the pristine analysis read-only.
The file drops from about 316 s to 15 s with the same 61 cases and
assertions; the snapshot's external zod path no longer names a pnpm
store version.

Type checks only need Host declarations and Typert-generated
declarations, but typecheck, lint, lint:fix, doc-typecheck, and the CI
typert-contracts gate rebuilt the whole Host tsdown pass, Desktop bundle
included, to obtain them. A source-only scripts/generate-typert.ts now
runs the same generator and artifact writer as the tsdown plugin, beside
Host package compilation: Typert reads only sources once the missing
@deepseek-ai/dsh-client-file-upload/types path alias exists, and
rejectBuildOutputs fails the pass when a workspace lib/ declaration
enters its program. typecheck runs as a build.ts scope that checks both
aggregates in build mode after their own face compiles.
Refs #5852
verify-package-paths reads root-relative packages/* strings in tests and
rejected the fixture's packages/generator, which names the real
packages/typert/generator leaf in the wrong group. The fixture now mirrors
that layout.

The client tsdown presets found a package's own manifest by name: a glob of
every packages/*/*/package.json, parsed until the name matched. tsdown's
native config loader imports each package config without module cache, so
the module-level cache never hit and all 82 configs repeated the glob
(40-125 ms each) synchronously on tsdown's main thread, where it delayed
every other package build. It was 34.5% of the client pass's main thread.
- clientBundle, staticLinked and clientLibrary take the package directory
(import.meta.dirname at every call site) and read <dir>/package.json
once; the package name, loader id and externals come from that manifest.
- A missing, unreadable or nameless manifest throws an actionable error.
- The glob, the name search and the module-level caches are removed.
tsdown client pass 12.78 s -> 8.73 s (median of 3 interleaved runs each,
-31.7%); all 11,566 lib outputs byte-identical; all 82 configs resolve the
same externals and banners.

The Host tsdown pass ran Typert synchronously inside the first package's
writeBundle, blocking every other workspace build's JavaScript hooks for
about 12 s. Discovery dominated that time: it expanded the Host aggregate's
2,064 include entries, parsed all 362 referenced tsconfigs (Client ones
included), and walked 322 packages although only 28 declare a Typert export.
- Select packages by their manifest exports before any source walk.
- Parse face aggregates without expanding their file lists.
- Parse package tsconfigs lazily, only for analyzed packages; tsc -b keeps
validating every referenced tsconfig.
- Resolve the workspace root as the nearest ancestor holding both
tsconfig.host.json and packages/.
- Run workspace generation in a Worker Thread started at the first
buildStart; writeBundle awaits it once and fails the build with
TypertWorkerError on any worker failure.
- Filter the decorator transform hook by id so only TypeScript modules
cross into JavaScript.
tsdown host median 22.6 s -> ~10 s; all 743 hashed lib outputs are
byte-identical except the generator's own bundle.
