Tier 3 — Experimental foundations (Phase 22)

Product strategy Tier 3 items are not v1 commitments. Phase 22 promotes each area from deferred to experimental with a documented golden path or minimal runtime.

Performance (Phase 18 P2) — complete

ID Item Status
P2.1 Slim CLI (--no-default-features --features slim) Complete
P2.2 Bridge timeouts (SPANDA_BRIDGE_TIMEOUT_SECS) Complete
P2.3 cargo audit CI job Complete

Observability (Phase 18 P3) — complete

ID Item Status
P3.1 Pipeline benchmark Completecargo test -p spanda-driver pipeline_bench -- --ignored

Runtime telemetry (RuntimeTelemetry, mission traces, trigger metrics) remains the production observability surface.

Still future (not experimental)
