docs(policy): create .claude/CLAUDE.md with TypeScript exemption table

Establishes the .claude/CLAUDE.md scaffold for this repo (previously
had no agent-instructions file). The body is intentionally short:
points at hyperpolymath/standards as the canonical policy source,
restates the key rules (no new TS, Deno not Node, AffineScript for new
code), and documents the 6 approved TypeScript exemptions in this repo
(MCP cartridge adapters in cartridges/*-mcp/adapter/mod.ts, all
gated on AffineScript MCP bindings).

Mirror tables exist in affinescript / standards / my-lang. Audit
lineage: TS-elimination audit, 2026-05-02.

+## Machine-Readable Artefacts
+
+This repo follows the hyperpolymath standard. See `https://github.com/hyperpolymath/standards` for the canonical 6-file `.machine_readable/` layout (STATE/META/ECOSYSTEM/AGENTIC/NEUROSYM/PLAYBOOK in A2ML format).
+
+---
+
+## Language Policy (Hyperpolymath Standard)
+
+The full policy is canonical in `hyperpolymath/standards`. Key points relevant to this repo:
+
+- **No new TypeScript** — convert existing TS to AffineScript (`.affine`) directly; ReScript is no longer the destination as of 2026-04-30.
+- **Deno** for the runtime, not Node. `deno.json` for imports, no `node_modules` in production.
+- **AffineScript** for new application code. Compiles to typed-wasm.
+
+### TypeScript Exemptions (Approved)
+
+The "no new TypeScript" rule has 6 approved exemptions in this repo — all MCP cartridge adapters. The MCP SDK (`@anthropic/sdk`) is TypeScript-native, and the adapters are JSON-RPC-over-stdio glue. Until AffineScript has bindings to the MCP protocol, these adapters must remain TS.
+
+| Path | Files | Rationale | Unblock condition |
+|---|---|---|---|
+| `cartridges/{academic-workflow,bofig,ephapax,fireflag,hesiod,sanctify}-mcp/adapter/mod.ts` | 6 | MCP cartridge adapters using `@anthropic/sdk`. The SDK is TS-native; equivalent functionality requires AffineScript bindings to MCP, which don't exist yet. | AffineScript MCP bindings (no scheduled issue — file under `affinescript` when scope is decided). |
+
+Adding to this list requires explicit user approval and an unblock condition. Audit lineage: TS-elimination audit, 2026-05-02. Mirror tables in `affinescript`, `standards`, and `my-lang` repos.
+
+### Documentation Format
+
+- All docs `.adoc` (AsciiDoc) except GitHub-required files (SECURITY.md, CONTRIBUTING.md, CODE_OF_CONDUCT.md, CHANGELOG.md).
