14-17: Verify the documentation flow after removing the explainer
The replacement of the "Interoperability explainer" with "Architecture" raises some concerns about the documentation flow:
- Is the explainer content merged into the architecture documentation?
- Should the architecture documentation come after a basic introduction to interoperability concepts?
Let's verify the content organization:
✅ Verification successful
Let me gather more information to verify if the explainer content exists elsewhere.
Documentation flow is properly maintained
The explainer content still exists at /stack/interop/explainer and serves as a comprehensive introduction to interoperability concepts. The architecture documentation complements it by providing technical details about implementation. The current card ordering is logical as:
- The explainer card links to fundamental concepts, definitions, and benefits of interoperability
- The architecture card links to technical implementation details that naturally build upon the basic concepts
Both documents are well-structured and maintain a clear learning path from basic to advanced concepts.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check if the explainer content exists elsewhere and verify the documentation structure
# Look for any references to the explainer
rg -i "interoperability explainer" --type mdx
# Check if architecture.mdx includes introductory content
fd -e mdx -e md "architecture" --exec head -n 20 {}
Length of output: 3001
Script:
#!/bin/bash
# Search for interoperability-related content in the codebase
rg -g "*.{md,mdx}" -i "interoperability" -B2 -A2
# Check the content of the interop directory

Incorporate safety level definitions into the main content
The commented-out safety level definitions provide valuable information that should be part of the main documentation.
Consider moving these definitions into the main content, structured as follows:
+## Safety level definitions
+
+Blocks in the system can exist in different safety states:
+
+* **Unsafe**: Not yet written to L1, obtained through gossip channels, ultimately based on trust in a sequencer.
+
+* **Cross unsafe**: Verified that all executing messages have legitimate initiating messages, but otherwise still unsafe. Treated as unsafe for most purposes.
+
+* **Safe**: The block and all blocks on which it depends (those with initiating messages to which it has executing messages) have been written to L1.
+
+* **Finalized**: The block and all blocks on which it depends have been on L1 for long enough to make a reorg impossible.Likely invalid or redundant comment.

48-86: LGTM! Clear and well-documented message flow
The sequence diagram and explanation effectively communicate the cross-domain messaging process. The links to specifications and implementation details provide valuable context.

1-5: Enhance the description to be more informativeThe current description "How it works" is quite brief. Consider expanding it to better reflect the document's content and purpose.
-description: How it works. +description: A comprehensive guide to the OP Stack interoperability architecture, explaining how OP-Supervisor enables cross-chain communication.
16-16: Maintain consistent capitalization of technical termsFor clarity and consistency, technical terms should maintain proper capitalization throughout the document.
-consensus client (e.g. op-node) +consensus client (e.g. OP Node)
22-23: Improve diagram contrast for better readabilityThe current light yellow background (#FFE) might not provide sufficient contrast. Consider using a slightly darker background color.
- classDef chain fill:#FFE + classDef chain fill:#F8F8E0,stroke:#333,stroke-width:2px
80-80: Fix typo in word "interoperates"-Any log event on any chain that inteoperates with the destination can initiate a cross domain message. +Any log event on any chain that interoperates with the destination can initiate a cross domain message.
82-84: Improve clarity of CrossL2Inbox explanationThe explanation of how transactions interact with CrossL2Inbox could be structured more clearly.
-The transaction that receives the message on the destination chain calls a contract called [`CrossL2Inbox`](https://specs.optimism.io/interop/predeploys.html#crossl2inbox). -This call can be at the top level, directly from the externally owned account, or come through a smart contract. +On the destination chain, the receiving transaction interacts with the [`CrossL2Inbox`](https://specs.optimism.io/interop/predeploys.html#crossl2inbox) contract in one of two ways: +1. Direct call from an externally owned account +2. Indirect call through another smart contract
123-124: Consider adding a summary table of safety levelsTo enhance understanding, consider adding a table that summarizes the different safety levels and their implications.
Add this table after the explanation:
| Safety Level | Description | Trust Requirements | |--------------|-------------|-------------------| | Unsafe | Not yet written to L1 | Trust all sequencers involved | | Safe | Written to L1, all dependencies are safe | Standard L1 trust assumptions | | Finalized | Immune from reorgs | Highest security level |
136-141: Fix formatting of bullet points and linksThe bullet points and links have inconsistent formatting and unnecessary line breaks.
