Switch DataModel::Provider to a span-based list iterator - flash and ram savings, simpler interface (#37033) * Copied over the new AttributePathExpandIterator and will incrementally use it (so I can validate tests) * Rename AttributePathExpandIterator to legacy * Prepare for using new style iterators ... checking NOT YET enabled though * Enabled checks ... and unit tests fail, but this now can be debugged * Fix some of the underlying bugs: read handling logic assumes we are ok to undo * Unit tests pass now * Restyle * Use new iterator in IME * Update logic to use the new iterator on testRead * more updates * Restyle * Remove the legacy attribute path expand iterator * Update naming * Restyle * Remove extra argument for ReadHandler constructor * Restyle * Slight flash improvement * Fix up includes * Removed empty line * added comment on why state is a friend class * Comment updates * Restyle, add some comments and add extra checks on validity check only for expansion. This saves a tiny amount of flash (32 bytes) * Remove an include * Comment updates, renamed mLastOutputPath to mOutputPath * Fix one typo * Re-arrange members of ReadHandler to optimize for memory layout. This saves 8 bytes for struct. We still have a 20-byte padding which I am unsure how to get rid of * Restyle * Rename State to Position * One more rename * Remove redundant assigment ...we are at a net 0 txt increase now on qpg * Add more unit tests for non-obvious requirement that wildcard expansion checks path validity, however non-wildcard does not check it * Update src/app/AttributePathExpandIterator.cpp Co-authored-by: Tennessee Carmel-Veilleux <tennessee.carmelveilleux@gmail.com> * Update src/app/AttributePathExpandIterator.h Co-authored-by: Tennessee Carmel-Veilleux <tennessee.carmelveilleux@gmail.com> * Update src/app/AttributePathExpandIterator.h Co-authored-by: Tennessee Carmel-Veilleux <tennessee.carmelveilleux@gmail.com> * Update src/app/AttributePathExpandIterator.h Co-authored-by: Tennessee Carmel-Veilleux <tennessee.carmelveilleux@gmail.com> * Update src/app/ReadHandler.h Co-authored-by: Tennessee Carmel-Veilleux <tennessee.carmelveilleux@gmail.com> * Update src/app/ReadHandler.cpp Co-authored-by: Tennessee Carmel-Veilleux <tennessee.carmelveilleux@gmail.com> * Update src/app/AttributePathExpandIterator.h Co-authored-by: Tennessee Carmel-Veilleux <tennessee.carmelveilleux@gmail.com> * Use different values for the cluster ids for testing * One more state to position change * mExpanded is now set during output path returning. Removed 2 more sets to save another tinier amount of .text * Import metadatalist class and test * Remove some tests that seem redundant, keep only one * Start with generated commands, see if we can replace its usage... * Unit tests for GeneratedCommands pass * Start with an implementation of accepted commands (no testing yet) * More tests pass * Updated AcceptedCommands as well .. unit tests pass * Restyle * Fix namespaces * Slight refactor. Code is still very much ugly * A bit of refactor, code looks better and tests pass now * Code compile for semantic tag ... made std::optional support non-trivial destructors * Update test * Make chip::Optional be trivially destructible if the underlying type is.

Matter (formerly Project CHIP) creates more connections between more objects, simplifying development for manufacturers and increasing compatibility for consumers, guided by the Connectivity Standards Alliance.
Matter is a unified, open-source application-layer connectivity standard built to enable developers and device manufacturers to connect and build reliable, and secure ecosystems and increase compatibility among connected home devices. It is built with market-proven technologies using Internet Protocol (IP) and is compatible with Thread and Wi-Fi network transports. Matter was developed by a Working Group within the Connectivity Standards Alliance (Alliance). This Working Group develops and promotes the adoption of the Matter standard, a royalty-free connectivity standard to increase compatibility among smart home products, with security as a fundamental design tenet. The vision that led major industry players to come together to build Matter is that smart connectivity should be simple, reliable, and interoperable.
Matter simplifies development for manufacturers and increases compatibility for consumers.
The standard was built around a shared belief that smart home devices should be secure, reliable, and seamless to use. By building upon Internet Protocol (IP), Matter enables communication across smart home devices, mobile apps, and cloud services and defines a specific set of IP-based networking technologies for device certification.
The Matter specification details everything necessary to implement a Matter application and transport layer stack. It is intended to be used by implementers as a complete specification.
The Alliance officially opened the Matter Working Group on January 17, 2020, and the specification is available for adoption now.
Visit buildwithmatter.com to learn more and read the latest news and updates about the project.
Matter is developed with the following goals and principles in mind:
Unifying: Matter is built with and on top of market-tested, existing technologies.
Interoperable: The specification permits communication between any Matter-certified device, subject to users’ permission.
Secure: The specification leverages modern security practices and protocols.
User Control: The end user controls authorization for interaction with devices.
Federated: No single entity serves as a throttle or a single point of failure for root of trust.
Robust: The set of protocols specifies a complete lifecycle of a device — starting with the seamless out-of-box experience, through operational protocols, to device and system management specifications required for proper function in the presence of change.
Low Overhead: The protocols are practically implementable on low compute-resource devices, such as MCUs.
Pervasive: The protocols are broadly deployable and accessible, by leveraging IP and being implementable on low-capability devices.
Ecosystem-Flexible: The protocol is flexible enough to accommodate deployment in ecosystems with differing policies.
Easy to Use: The protocol provides smooth, cohesive, integrated provisioning and out-of-box experience.
Open: The Project’s design and technical processes are open and transparent to the general public, including non-members wherever possible.
Matter aims to build a universal IPv6-based communication protocol for smart home devices. The protocol defines the application layer that will be deployed on devices and the different link layers to help maintain interoperability. The following diagram illustrates the normal operational mode of the stack: 
The architecture is divided into layers to help separate the different responsibilities and introduce a good level of encapsulation among the various pieces of the protocol stack. The vast majority of interactions flow through the stack captured in the following Figure:
Security: An encoded action frame is then sent down to the Security Layer to encrypt and sign the payload to ensure that data is secured and authenticated by both sender and receiver of a packet.
Message Framing & Routing: With an interaction encrypted and signed, the Message Layer constructs the payload format with required and optional header fields; which specify the message's properties and some routing information.
Matter’s design and technical processes are intended to be open and transparent to the general public, including to Working Group non-members wherever possible. The availability of this GitHub repository and its source code under an Apache v2 license is an important and demonstrable step to achieving this commitment. Matter endeavors to bring together the best aspects of market-tested technologies and redeploy them as a unified and cohesive whole-system solution. The overall goal of this approach is to bring the benefits of Matter to consumers and manufacturers as quickly as possible. As a result, what you observe in this repository is an implementation-first approach to the technical specification, vetting integrations in practice. The Matter repository is growing and evolving to implement the overall architecture. The repository currently contains the security foundations, message framing and dispatch, and an implementation of the interaction model and data model. The code examples show simple interactions, and are supported on multiple transports -- Wi-Fi and Thread -- starting with resource-constrained (i.e., memory, processing) silicon platforms to help ensure Matter’s scalability.
