Stacked on #429 (chore/oxlint-anti-slop-setup). This PR makes the newly enabled OXLint anti-slop rules pass by changing code, not by weakening oxlint.config.ts or adding file-level disables.

Widened unknown and implicit any are replaced with JsonValue / WireInput and named parsers (jsonKind, isJsonObject, unsafeNarrow). Runtime typeof checks go through those classifiers. Type assertions stay only at SDK, JSON, and protocol boundaries, each with a SAFETY: comment. Unused bindings are dropped, optional chaining is guarded, control-character scans use char-code loops instead of control regexes, and Result.gen keeps this via .bind(this) instead of a this alias.

Two real bugs showed up while doing that. Unwrapping server.registerTool with unsafeNarrow dropped this, so the MCP SDK could not read _registeredTools; the call is now bound. Running prototype-poisoned JSON through jsonValueSchema.parse dropped __proto__ as an own key; that fixture still uses a raw parse so the own-property invariant holds.

Justified inline disables (both in src/json-value.ts, JSON contract types):

• anti-slop/no-unsafe-dictionary-type on JsonObject — JSON objects are an open string-keyed map by contract.
• anti-slop/no-unsafe-dictionary-type on JsonValue — JSON values include nested objects with string keys.

CI now runs pnpm lint next to typecheck and test. Verified locally: pnpm lint 0 errors / 0 warnings, pnpm typecheck pass, pnpm test 548 pass / 4 skip / 0 fail, pnpm build pass, pnpm test:package-install pass.

Walkthrough

The pull request adds shared JSON wire-value types and validation helpers, then applies them across application code, tests, and QA/replay tooling. It also adds pnpm lint to CI. Most execution flows and test outcomes remain unchanged.

Changes: Shared JSON wire-value cleanup

Layer / File(s)	Summary
Shared JSON types and guards src/json-value.ts, src/unsafe-narrow.ts, src/*	Adds JsonValue, JsonObject, and WireInput types, JSON validators, parsing helpers, and optional-field helpers. These types and helpers are used in workflow, local-agent, artifact, server, UI, and other code paths.
Provider, daemon, workflow, and activity paths src/local-agent-*, src/workflow-*, src/server.ts, src/workspace-activity-*, src/artifact-*	Replaces broad unknown and generic record annotations with shared wire types and guarded access. Existing validation rules and execution flows are generally retained.
QA, replay, tests, and supporting changes scripts/qa/*, test/agents-replay/*, src/**/*.test.ts, website/*, .github/workflows/ci.yml	Updates QA and replay value handling and test typing. Adds pnpm lint to CI. Other changes are formatting, safety comments, and type inference adjustments.

1-2: Trivial · Performance & Scalability · Low value

Hoist the Zod guard schemas as an optional allocation refactor.

UI render and result-processing paths call these helpers, and each call constructs a new Zod schema. Hoisting the schemas avoids those repeated allocations. This does not remove Zod from the browser bundle. No evidence establishes a meaningful user-visible cost, so this is an optional refactor rather than a defect.

Suggested fix

 export type WireInput = {} | null | undefined;

+const jsonStringSchema = z.string();
+const jsonNumberSchema = z.number();
+const jsonBooleanSchema = z.boolean();
+const bigintSchema = z.bigint();
+const symbolSchema = z.symbol();
+const functionSchema = z.function();
+
 export const jsonValueSchema: z.ZodType<JsonValue> = z.lazy(() =>
   z.union([
     z.null(),
-    z.boolean(),
-    z.number(),
-    z.string(),
+    jsonBooleanSchema,
+    jsonNumberSchema,
+    jsonStringSchema,
     z.array(jsonValueSchema),
-    z.record(z.string(), jsonValueSchema),
+    z.record(jsonStringSchema, jsonValueSchema),
   ]),
 );

 export function isJsonString<T>(value: T): value is T & string {
-  return z.string().safeParse(value).success;
+  return jsonStringSchema.safeParse(value).success;
 }

 export function isJsonNumber<T>(value: T): value is T & number {
-  return z.number().safeParse(value).success;
+  return jsonNumberSchema.safeParse(value).success;
 }

Apply the same replacement to the other primitive guard helpers and use functionSchema in isObjectValue.

Minor · Functional Correctness · Quick win

validateJson no longer rejects NaN or ±Infinity.

isJsonNumber(current) is backed by Zod 4 z.number(), which already rejects non-finite values. The !Number.isFinite(current) branch is therefore unreachable. JSON.stringify then writes null for these values.

Workflow arguments, events, agent results, nested workflow results, and the final workflow result pass through this function. A non-finite number is now silently changed to null. Before this change, it failed with WORKFLOW_INVALID_JSON. encodeJson in src/workflow-runner-child.ts has the same defect.
