Zig encoding, decoding, and routing use ChangesNumeric wire message types
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This change can reject valid AuthRefresh requests, and several updated tests do not reliably validate the intended numeric message types. The PR is not merge-ready until the protocol rule and affected test coverage are corrected and the required validation commands pass. Sequence Diagram(s)sequenceDiagram

20-24: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick winAssert the MessagePack width, not only the decoded value.
expectTypechecks the value after decoding. It does not detect an encoder that writes the same ID asuint8,uint16, oruint64. The protocol requires assigned IDs to remain one-byte positive fixints. Add a raw-byte assertion for at least one top-level response, or make the helper inspect the original bytes.🤖 Prompt for AI Agents

In `@sdk/typescript/src/test-helpers.ts`:
- Around line 13-20: Update the registry-key check in the test helper’s
wire-message conversion logic to accept only own keys of WireMessageType,
preventing inherited names such as “constructor” from being converted; preserve
unrecognized type strings unchanged.
In `@specs/implementation/query-grammar.md`:
- Line 68: Update the JSON example’s type value from hexadecimal 0x14 to decimal
20 so the block remains valid JSON, while retaining 0x14 only in explanatory
text if needed.
In `@specs/implementation/wire-protocol.md`:
- Around line 123-125: Update the Direction rules for server-only IDs to exclude
AuthRefresh (0x04), listing 0x00–0x03 and 0x05 separately or deriving the check
from MessageType direction cases, so valid AuthRefresh client requests are not
rejected.
In `@src/wire/decode_test.zig`:
- Around line 122-124: Update both unsubscribe fixtures in the decode tests to
use MessageType.store_unsubscribe, which maps to 0x16, instead of the raw 0x15
literal; leave the subscribe fixtures unchanged.

In `@src/wire/encode_test.zig`:
- Around line 20-26: Update expectType to parse the top-level map entry
structurally rather than searching the entire bytes buffer for type_key.
Validate the map header and entry boundaries, locate the top-level "type" key,
and bounds-check before reading its value so nested payloads and truncated
matches cannot be mistaken for the type field.
