ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This change introduces a Node single-executable build path while rewiring existing HTTP, PTY, SQLite, and platform-service behavior from runtime-selected Bun/Node implementations to Node-only implementations. It also adds static-analysis suppression directives and changes native dependency loading and packaging, giving the PR a broader blast radius than a self-contained build tweak. Notes:

Inside a Node SEA, import statements and import() can only resolve built-ins, so the two external native packages (fff-node, node-pty) now load through createRequire. fff-node's exports map only declared an import condition, so the existing patch also adds a require condition. Adds a build-exe subcommand that wraps the bundle with tsdown's exe support and fails if the emitted bundle still imports any file-backed package, since that only surfaces at runtime inside the executable.

Node's SEA docs state import() does not work with useCodeCache, and the server loads several modules that way. The bundle scan now also catches side-effect imports and re-exports. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Part 2 of 8 (stack #11411) toward shipping the
t3CLI as a self-contained executable so runtime installers never resolve or build dependencies again (#11208, #6012, #9398 are all install-time failures of that kind).Problem
A Node single-executable (SEA) can only
importbuilt-in modules; any file-backed specifier throws at module evaluation (static) or on first use (dynamic). The server bundle keeps three native packages external (fff-node, node-pty, msgpackr-extract), and two of them were reached through ESM imports, so the executable died on startup withERR_UNKNOWN_BUILTIN_MODULE: @ff-labs/fff-node.Fix
WorkspaceSearchIndexandNodePtyAdapterload their native package throughcreateRequire, which reads the real filesystem in every runtime. The pty loader becomes aContext.Referenceso the adapter test can inject a fake module (module mocks no longer interceptrequire).exportsmap only declared animportcondition, sorequire()failed withERR_PACKAGE_PATH_NOT_EXPORTED; the existing pnpm patch adds arequirecondition.build:exescript /cli.ts build-exewraps the bundle with tsdown'sexesupport (Node ≥ 25.7 on the build host; the repo stays on 24) and fails if the emitted bundle still contains an ESM import of a file-backed package.findEsmImportsOfExternalPackagesreads the artifact rather than trusting bundler config, the same reasoning as the existing inlined-package scan.No distribution changes yet:
dist/bin.mjsand the npm package are unchanged apart from the two loader edits.Verification

New Features
t3executable.Bug Fixes
Update: Bun runtime branches removed
Since the server now ships as a Node single-executable and is never run under Bun, this layer also drops every Bun-specific path:
BunPtyAdapter, theBunHttpServer/BunServicesselection inserver.ts, thebun:sqliteclient selection in the persistence layer, the@effect/platform-bunand@effect/sql-sqlite-bundependencies, and the build-only external exemption that existed to keep those imports unresolved. Each service now has one implementation.
