Objective

Implement seed-cap discovery, event queue polling/acknowledgment, message decoding, caps-to-packet translation, recovery, and shutdown.

Deliverables

Preserve LLSD request/response shapes, queue IDs, ack progression, timeouts, retries, event ordering, unknown events, and reconnect behavior.
Bound event payloads and queue fan-out.
Route decoded events through the same typed dispatch contracts as UDP.

Validation

Event queue and message-decoder tests pass.
Cancellation ends polling promptly without lost owned tasks.
Recorded event fixtures replay deterministically.

Prerequisite

Wire codegen and the foundational implementation milestones are complete; the fixed API/test gates remain authoritative.

Project constraints

Native Rust networking only; no C# bridge, helper service, subprocess, or fallback.
Keep mapped APIs and translated assertions fixed, use bounded resources, and never log secrets.
Validate offline with deterministic fake servers before live-grid use and update docs/coverage evidence.

Implement capability event queue processing (#55)

hugo commented

Implemented and pushed in aa269f1.

Native Rust implementation now covers seed-cap discovery, the complete reference capability request list, URI registration, bounded EventQueueGet polling, ack/done progression, ordered event delivery, transient recovery, terminal statuses, deterministic jitter, reconnect/start behavior, prompt cancellation, graceful shutdown, joined task ownership, typed CAPS dispatch, and caps-to-packet fallback. MessageUtils now decodes every named event in the C# reference switch with native LLSD codecs, including polymorphic search/upload/object-media variants, display names, physics, attachment resources, and bulk inventory. Unknown or malformed events remain safe and use packet fallback where a packet schema exists. Documentation and shim coverage were updated.

Verified in isolation:

5 event_queue tests passed
2 caps tests passed
7 message_decoder tests passed
3 network_manager dispatch/lifetime tests passed
11 caps_http integration tests passed
packet_osd, generated codec, and relevant compatibility tests passed
API compile fixture passed
generator drift check passed
cargo clippy -p libremetaverse --lib --no-deps --locked -j1 -- -D warnings passed on Rust 1.97
rustdoc with -D warnings passed
cargo check --workspace --all-targets --locked -j1 passed

The broad pre-created lib test run has 65 passing tests and 70 expected failures confined to unimplemented later-milestone appearance, archive, animesh, inventory/AIS, and world/estate domains; no #55 test failed.
