Highlights

• Block Exporter (ARC-443): Introduces block-exporter for emitting chain data to external sinks, enabling downstream analytics and archiving.
• Runtime Observability (ARC-474): Populates observability stack with richer runtime metrics for improved monitoring and alerting.
• Consensus and stability: Added timeout on consensus-ready states and timer cleanups to improve liveness and correctness.
• Programs: New system instruction to sign inputs; example programs refactored and warnings addressed.
• APIs: Simplified blockchain info APIs for easier consumption.
• DevEx: Earthly +local debug mode; removed commented code; testing suite tuning (Titan main loop interval set to 0).

Added

• block-exporter crate for exporting blocks and related metadata.
• Runtime metrics wiring to the observability stack.
• System instruction: sign input.
• Debug mode with Earthly +local.

Changed

• Consensus readiness now has timeouts; timers cleaned and rationalized.
• Vote example refactor; program stubs warnings fixed.
• Blockchain info APIs simplified for clients.
• Testing suite: Titan main loop interval set to 0 for faster cycles.

Fixed

• Addressed audit findings and various cleanups across the codebase.

Performance and Observability

• New metrics significantly improve visibility into runtime behavior.
• Testing loop adjustments reduce iteration time; exporter enables external analysis pipelines.

RPC and API Changes

• Blockchain info APIs simplified; no known breaking external changes.
• New system instruction for signing inputs expands program capabilities.

Breaking Changes

• None known.

Migration Guidance

• If consuming blockchain info APIs, review simplified shapes/fields.
• Integrators can adopt block-exporter for downstream processing.

Documentation

• No major docs added; examples and internal references updated.
