OpenClaw Signals: CLI Caching, Resolver RFCs, and Zombie FDs

Tools

New CLI query cache to oc

We shouldn't be re-inventing the wheel for every CI run. If this query helper lands, it's going to save a ton of compute time by caching compiled artifacts between builds.

PR #329: Add stricter payload sanitization

Finally cleaning up the webhook schema validation. Getting strict here prevents a whole class of silent failure modes when payloads drift out of spec.

Architecture

PR #332: Fix lifecycle timeout limits

Edge cases in connection handshakes were causing state machines to hang. This patch hardens the lifecycle transitions, which is critical for distributed reliability.

Operations

PR #331: Memory trim in query plan serializer

JSON serialization of query plans was eating too much RAM. This perf patch should help if you're dumping heavy debug logs in high-throughput scenarios.

Bugs

Issue #1564: FD Leak on stream cutoff

Async cleanup on stream termination was leaving zombie file descriptors. A classic resource leak that's finally getting patched.

Strategy

Issue #1563: RFC - Standalone Resolver module

There's a proposal to separate the Resolver component into its own interface. If this gains traction, it opens the door for swapping out custom resolution logic without forking the core.
