Running the matrix against a live gateway surfaced several issues:
- The write phase is now opt-in (-VerifyWrite, was -SkipWrite). It runs
right after register so only a small event backlog precedes the write,
and asserts the reliable OnWriteComplete signal (the written value is
not echoed back by a provider-driven attribute like TestChangingInt, so
the value compare is best-effort).
- Java was launched as bare "gradle", which .NET's Process.Start cannot
exec (it is gradle.bat) — resolve the launcher and run it via cmd.exe.
- The Java client's MxEventStream queue capacity was 16, which overflows
on any active session's backlog-replay burst; raised to 1024.
- The Rust stream-events CLI now renders the event family as the proto
enum name, matching the protobuf-JSON the other four clients emit.
Update docs/GatewayTesting.md for the reworked write phase.
Verified live: the full five-client matrix passes with -VerifyWrite.

Close the notable gaps in scripts/run-client-e2e-tests.ps1:
- Write round-trip: write a per-client sentinel value to a configurable
writable attribute, then assert it is echoed back through the event
stream. Extends the Rust mxgw-cli stream-events output with full
per-event JSON (itemHandle + protojson-shaped value) so all five
language clients run an identical value compare.
- Parity: assert an invalid item handle and an unknown session id are
rejected rather than silently succeeding.
- Auth rejection: assert open-session is rejected with a missing API key
and, when -RejectScopeApiKeyEnv is supplied, with an insufficient-scope
key.
- Parallel: -Parallel runs each language client as an isolated child
process and merges their JSON reports.
Update docs/GatewayTesting.md for the new phases and flags.

Resolves Client.Rust-001 through Client.Rust-011.
Build/test/clippy gate (Client.Rust-001/002/003):
- options.rs: doc comments on with_max_grpc_message_bytes /
max_grpc_message_bytes (#![warn(missing_docs)])
- session.rs: rename BulkReplyKind variants to drop the shared `Bulk`
suffix (clippy::enum_variant_names)
- galaxy.rs: deref instead of clone on Option<Timestamp>
(clippy::clone_on_copy — an extra violation the gate also hit)
- mxgw-cli: assert version_json against GATEWAY/WORKER_PROTOCOL_VERSION
constants instead of the stale literal 2
`cargo clippy --workspace --all-targets -- -D warnings` now passes.
Correctness / error handling:
- version.rs: CLIENT_VERSION = env!("CARGO_PKG_VERSION") (Client.Rust-004)
- session.rs: register/add_item/add_item2 handle extractors and
bulk_results now return Err(Error::MalformedReply) instead of a
silent 0 / empty vec on a shapeless OK reply (Client.Rust-005/006)
- error.rs: new Error::Unavailable classifies Code::Unavailable /
ResourceExhausted as transient (Client.Rust-010)
- session.rs: per-call unique correlation ids via an atomic counter
(Client.Rust-011)
Other:
- value.rs: MxValue/MxArrayValue compute the projection on demand
instead of caching it, so a wire-only value pays no projection cost
(Client.Rust-008)
- RustClientDesign.md: correct the crate layout, drop the unused
`tracing` dependency (Client.Rust-007)
- client_behavior.rs: tests for the bulk-size cap, a mid-stream status
fault, and the unreadable-CA-file path (Client.Rust-009)
cargo fmt / test --workspace (27 tests) / clippy all pass.

- Resolve 14 conflicts from popping local stash on top of origin's
eed1e88 + 8d3352f doc-comment additions (11 mechanical, plus
version.rs, DashboardAuthenticatorTests.cs, DashboardGalaxyProjector.cs)
- Fix 4 test files that used AGENTS.md as the repo-root sentinel
(now use CLAUDE.md, since AGENTS.md was removed in 4731ab5)
- Redirect 10 doc citations from AGENTS.md to the matching gateway.md
sections (Value Model, Status Model, Security, STA Worker Thread
Model, gRPC Layer rule, cancellation rule)
Verified: solution build clean, x86 worker build clean, 266/266
gateway tests passing, 121/121 worker tests passing.
