 - `stacks/lint` and `stacks/test` are deliberate near-verbatim copies of the upstream extensions, kept close to upstream so changes can be synced by diffing. Do NOT deduplicate or refactor across the two stacks — the duplication is the point; consolidation is a later, explicit phase.
 - The copies diverge from upstream in exactly twelve ways (the "adaptations" below). When syncing upstream, preserve them. A thirteenth divergence is either a bug or must be added to this list.
 - **Tracked upstream state.** `stacks/lint` tracks web-infra-dev/rslint `packages/vscode-extension` at **e5d76242** (0.9.3); `stacks/test` tracks web-infra-dev/rstest `packages/vscode` at **e1607861** (post-0.12.2 main). Additional ports: Rslint **84f9c9b5** trace wording and **72cd2b1f** fixAll waits; Rstest **988f8e1d** per-bundle license notices, with explicit native-binding inclusion and no network license-text replenishment. We replace upstream's plugin-host failure toast with status (adaptations 4/7). Diff `CoreResolver.ts`, `RuntimeManager.ts`, `WorkspaceDocumentRouter.ts`, and `Rslint.ts` on future syncs. The rstest#1888 IPC port uses default JSON instead of advanced serialization: values must survive a JSON round-trip, and both `createBirpc` calls spread `rpcErrorCodec` (`stacks/test/shared/rpc.ts`) to preserve thrown errors. Failed-project retry and worker cleanup remain ahead of upstream.
-- **Ahead of upstream — offer these back when syncing** (bug fixes, not adaptations): (1) `RuntimeManager.reconcile` resolves the document's core **before** sweeping pending uses (`planDocumentCore`), so a reconcile landing on the key a pending start is already producing adopts that start instead of tearing it down mid-`initialize` — the teardown made vscode-languageclient force-notify ("couldn't create connection to server") whenever the register-time pass, a detection change and `didOpen` landed inside one worker startup window (`tests/stacks/lint/runtimeManager.test.ts`). (2) `Rslint.close()` gives a still-Starting language client a bounded chance to settle before tearing down its transport, so a legitimate mid-start close (document closed during start, core key changed) stops cleanly instead of triggering the same force-notified toasts. (3) The registry-harness E2E gives its never-settling startup operation 500ms to begin and accepts only the in-flight timeout message, so a stalled runner cannot satisfy the assertion through the already-expired path (`e2e/lint/suite/registry-harness.test.ts`). (4) `Project.retryFailedConfig()` keeps a failed Rstest project and retries its config evaluation in place with one single-flight promise, so repeated dependency-change passes neither overlap workers nor repeat an unchanged not-installed warning. (5) `RuntimeManager` retires a stopped client even when its resolved key is unchanged. The existing closing barrier and pending-use adoption share one replacement across documents; running and starting clients remain untouched (`tests/stacks/lint/runtimeManager.test.ts`).
