WalkthroughThe sidebar configuration and documentation structure were reorganized. New documentation was added for data availability, sequencing, and execution under the "Learn" section. Several guides were removed or consolidated, including deletion of specific DA and sequencing guides. The sidebar now features clearer grouping of related topics and updated navigation paths. Changes

Summary of Changes
Hello @pthmas, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly reorganizes the project's documentation by creating a new 'learn' section for conceptual topics like Data Availability and Sequencing. It aims to improve the clarity and discoverability of information by centralizing key knowledge and providing dedicated guides for core components.
Highlights
- Documentation Reorganization: Core documentation on Data Availability (DA) and Sequencing has been restructured, moving conceptual and detailed content into a new
/learnsection for better accessibility and clarity. - New DA Overview: A new
learn/data-availability.mdfile has been added, providing a comprehensive overview of Data Availability within the Rollkit framework. - New Single Sequencer Guide: A dedicated guide for the single sequencer model has been introduced at
learn/sequencing/single.md, detailing its functionality, benefits, and considerations. - Navigation Updates: The sidebar navigation in
.vitepress/config.tshas been updated to reflect the new documentation structure, including new top-level 'Data Availability' and 'Sequencing' entries under the 'Learn' section, and updated links for existing guides.

Code Review
This pull request reorganizes documentation for Data Availability and Sequencing by moving content from guides to a new learn section and adding new explanatory pages. The changes improve the structure of the documentation. A critical typo in the VitePress configuration would lead to broken links, and there are also a few medium-severity issues in the new markdown files, including a typo and inconsistent link formatting.

3-3: Tighten wording by dropping filler phraseThe phrase “This means you can use a variety of” is verbose and can be trimmed without losing meaning.
-Rollkit is designed to be modular and flexible, allowing different execution layers to be plugged in via the ABCI (Application Blockchain Interface) protocol. This means you can use a variety of ABCI-compatible applications as the execution environment for your rollup. +Rollkit is designed to be modular and flexible, allowing different execution layers to be plugged in via the ABCI (Application Blockchain Interface) protocol, so any ABCI-compatible application can serve as the execution environment for your rollup.
7-11: Use relative links & reference concrete integration guideExternal links are useful, but an internal “Cosmos SDK integration” guide (if present or planned) would be more actionable and future-proof. Consider:
-### Cosmos SDK App -A Cosmos SDK-based application can serve as the execution layer for a Rollkit rollup. This allows you to leverage the rich ecosystem and features of the Cosmos SDK, including modules for staking, governance, IBC, and more. - -- [Cosmos SDK Documentation](https://docs.cosmos.network/) +### Cosmos SDK App +A Cosmos SDK-based application can serve as the execution layer for a Rollkit rollup, letting you reuse modules for staking, governance, IBC and more. + +- [Official Cosmos SDK docs](https://docs.cosmos.network/) +- [Rollkit × Cosmos SDK integration guide](../execution/cosmos-sdk.md) <!-- add/ensure this doc exists -->
12-16: Mirror structure & clarify smart-contract angleMinor restructuring improves parallelism with the previous subsection.
-### CosmWasm -CosmWasm is a smart contract platform built for the Cosmos ecosystem. It is ABCI-compatible and can be integrated as the execution layer in Rollkit, enabling your rollup to support WebAssembly (Wasm) smart contracts. - -- [CosmWasm Documentation](https://docs.cosmwasm.com/) +### CosmWasm +CosmWasm is a smart-contract platform for the Cosmos ecosystem. Because it exposes an ABCI interface, it can act as the execution layer in Rollkit, enabling Wasm smart-contracts on your rollup. + +- [Official CosmWasm docs](https://docs.cosmwasm.com/) +- [Rollkit × CosmWasm integration guide](../execution/cosmwasm.md)
17-22: Consider adding a simple sequence diagramThe bullet list is clear, but a visual (Mermaid) sequence diagram would convey the ABCI message flow at a glance.
Example insertion:
```mermaid sequenceDiagram participant User participant Rollkit participant ExecutionLayer User->>Rollkit: Submit Tx Rollkit->>ExecutionLayer: DeliverTx (ABCI) ExecutionLayer-->>Rollkit: Response Rollkit-->>User: Tx resultHelps readers who are new to ABCI quickly grasp the interaction. --- `25-29`: **Add a “Limitations” or “Gotchas” callout** The Benefits section is great, but balancing it with limitations (e.g., ABCI overhead, consensus-state sync requirements, version-compatibility) sets proper expectations and pre-empts support questions. A simple admonition block could work: ```markdown ::: warning Limitations ABCI adds an extra process boundary, so latency is higher than monolithic nodes. Ensure version compatibility between Rollkit and the execution layer during upgrades. :::

| ## Advantages | ||
|
|
||
| - **Simplicity:** Easy to set up and operate, making it ideal for development, testing, and small-scale deployments. | ||
| - **Low Latency:** Fast block production and transaction inclusion, since there is no consensus overhead among multiple sequencers. | ||

||
| - Production rollups seeking simplicity and performance | ||
| - Prototyping and development | ||
| - Private or permissioned rollups | ||
| - Projects that value deterministic ordering and operational control |

these sections read weird. use cases feels too naive, it should be its own section with case studies.
advantages would be good to call something else as its unclear what the comparison is on

11-13: Clarify ABCI scope to avoid earlier confusion.Previous review feedback noted that ABCI is specific to Cosmos SDK. Consider explicitly stating that ABCI support is only for Cosmos-SDK execution layers to avoid implying other environments must implement it.
Example:
-Rollkit natively supports Cosmos SDK-based applications as the execution layer for a rollup via the ABCI (Application Blockchain Interface) protocol. +For Cosmos-SDK execution layers, Rollkit communicates via the ABCI (Application Blockchain Interface) protocol.

3-3: Link to a movingmainbranch is brittle – pin to a tagged commit or docs site.Linking directly to

11-15: Re-verify the “via the ABCI protocol” claimPast feedback (see previous review thread) indicated confusion about whether Rollkit actually communicates with Cosmos-SDK apps over ABCI or through its own adapter layer. If the adapter implements a superset or a different transport, we risk misleading readers.
Please double-check the integration path and rephrase if it is not literally ABCI:
-Rollkit natively supports Cosmos SDK-based applications as the execution layer for a rollup via the ABCI (Application Blockchain Interface) protocol. +Rollkit natively supports Cosmos SDK-based applications through its ABCI-compatible adapter layer.
