+Implemented the first Pod-layer feature contribution registry slice. Added pod::feature with descriptors, contribution registrars, host-authority model, service/background descriptor skeletons, notification/alert/diagnostic sinks, descriptor-approved contribution checks, once-materialized tool registration, and installed Task tools through the normal Worker tool path. External plugin loading, real approval resolver, full background/service runtime, and WorkItem/MCP integrations remain follow-up scope. Final external review approved. Merge validation passed: cargo test -p pod --lib feature::tests --no-fail-fast, cargo test -p pod --lib, cargo test -p llm-worker --lib, cargo fmt --check, cargo check --workspace --all-targets, ./tickets.sh doctor, git diff --check, nix build .#yoi, ./result/bin/yoi pod --help.

 Residual risk is acceptable for this slice. The registry is still a skeleton for external plugins: background tasks, services, notification sinks, alert sinks, and authority grant resolution are represented but not fully connected to production host lifecycles or approval policy. That is consistent with the ticket’s first-slice scope as long as follow-up work does not treat this as external-plugin-ready without adding the real host policy, lifecycle, and bounded-output enforcement.
