Adding pub mod trie is a welcome addition. Confirm that integration or unit tests exist to validate the new trie functionality, ensuring correct handling of proof generation and state queries.

2-2: Ohayo sensei! Kudos on adding FromStr.

Bringing FromStr into scope paves the way for user-friendly parsing of contract addresses. Make sure you handle invalid parsing inputs gracefully in higher-level logic.

58-62: Ohayo sensei! The AsRef<Felt> implementation adds flexibility.

Referencing the underlying Felt directly from a ContractAddress is convenient. Keep an eye on usage in places that might require further type checks or validations.

8-8: Ohayo sensei! Database version bumped to 6 successfully.

Make sure to update any relevant migration scripts or documentation referencing version 5. This ensures developers and ops teams are aware of the new versioning requirements.

Also applies to: 84-84

9-9: Ohayo sensei! Excellent switch to the new state traits.
By removing StateRootProvider and importing StateFactoryProvider, StateProvider, and StateWriter here, you've streamlined the interface. This better aligns with the consolidated approach to handling state operations.

7-7: Ohayo sensei! Using constants from rpc config is a clean approach.
Bringing in DEFAULT_RPC_ADDR and DEFAULT_RPC_MAX_CONNECTIONS helps maintain consistent configuration defaults across the codebase. Great job keeping everything centralized.

125-125: Ohayo sensei! Adopting RpcModulesList::all().
This is consistent with the shift toward a more extensible RPC configuration. Keep in mind that if certain modules should remain disabled in some environments, providing a filtered list might be preferable.

128-128: Ohayo sensei! Introducing max_proof_keys is a neat addition.
Setting Some(100) ensures large proof requests are capped, preventing excessive resource consumption. Verify that 100 is sufficient for real-world scenarios or consider making it configurable via CLI flags.

36-36: Ohayo sensei! Good clarity on db_handles initialization.
Using RwLock::new([None; NUM_TABLES]) explicitly clarifies the intended initial state. This approach removes ambiguity from relying on Default::default().

9-9: Ohayo sensei! Excellent inclusion of the new state traits.
Importing both StateProofProvider and StateRootProvider opens up more comprehensive coverage for verifying and retrieving state proofs and roots.

199-211: Ohayo sensei! Straightforward StateRootProvider stubs.
Providing root values of zero for classes, contracts, and storage is consistent with the no-op design. This setup is convenient for testing scenarios that do not rely on actual state data.

69-70: Ohayo sensei! Nice grouping of reference-based traits.
This comment is mostly about commending the introduction of code references. It's beneficial for memory usage and clarity, as it enables operations on borrowed transactions without always needing ownership. The addition is neatly modular.

94-128: Ohayo sensei! Verify concurrency aspects here.
The DbTxMutRef trait carefully extends DbTxRef with mutable database operations. Yet, if the underlying database engine or usage pattern doesn't fully support concurrent mutations, ensure these trait methods are used safely. A clarifying doc comment about concurrency or locking requirements might help.

130-149: Ohayo sensei! Implementation detail using trait forwarding is well done.
Forwarding calls via impl<'a, Tx: DbTx> DbTxRef<'a> for &'a Tx looks neat. This maintains DRY principles, reusing the existing DbTx implementation, and the design helps keep the code maintainable.

151-180: Ohayo sensei! Validate that references won’t outlive transactions.
Because we’re referencing Tx in the implementation for DbTxMutRef, watch for potential lifetime pitfalls if the underlying transaction can be invalidated. Ensure no hidden footguns like using these references after transactions are dropped.

6-6: Ohayo sensei! Great addition of ClassHash import.
This provides more clarity about the typed nature of class hashes. Confirm that only relevant parts of katana_primitives::class are imported to avoid bloat.

22-22: Ohayo sensei! ContractStorageKeys import complements the new proof functionality neatly.
No immediate concerns. Just ensure consistent usage with the rest of the codebase.

189-199: Ohayo sensei! New method get_storage_proof elevates the API’s introspection capabilities.
Fetching proofs is crucial for trustless verification. Check for input validation and limits around class_hashes, contract_addresses, etc., to guard against malicious requests.

4-4: Ohayo sensei! Good choice to import ClassHash for clarity.
It’s consistent with the new proof approach, though confirm that the next maintainers are aware of the difference between Felt and ClassHash usage.

6-6: Ohayo sensei! The combined import of ContractAddress and Felt keeps the code DRY.
No issues found; it’s neatly done.

19-19: Ohayo sensei! ContractStorageKeys import completes the puzzle for multiproof logic.
Looks aligned with the rest of the code changes for verifying contract states.

14-14: Ohayo sensei! The rename from ApiKind to RpcModuleKind is a neat improvement.
This naming is more intuitive for new devs. Keep an eye out for references in doc comments or config scripts.

278-278: Ohayo sensei! Condition for Dev module is straightforward.
No major remarks here; keep an eye on whether Dev-specific endpoints remain well-isolated from production.

283-283: Ohayo sensei! Condition for Torii endpoints is consistent.
Ensures Torii is only exposed when specifically included.

288-288: Ohayo sensei! Saya API gating looks good.
Just confirm each additional RPC module is tested to ensure it doesn’t break the runtime if toggled off.

14-14: Ohayo sensei, consider confirming removal of StateRootProvider.
Removing this import aligns with the broader changes. If it's still needed elsewhere, you might want to revisit.

32-32: Ohayo sensei, ignoring forked-mode tests.
These tests are crucial for comprehensive coverage. Please ensure you re-enable them once forked-mode consistency is established.

49-49: Ohayo sensei, ignoring test for empty forked blocks.
Similar note as above—ensure these tests get restored or supplemented later to maintain coverage.

70-70: Ohayo sensei, neat extension of trait bounds with StateFactoryProvider.
This broadens the provider's functionality seamlessly.

124-125: Ohayo sensei, watch out for potential None from historical lookups.
When None is returned, ensure you handle it gracefully to avoid panics or unexpected logic flows.

180-180: Ohayo sensei, consistent trait usage with StateFactoryProvider.
This inclusion keeps your code aligned with the rest of the refactor.

231-232: Ohayo sensei, double-check the map and transpose usage for potential edge cases.
The historical(...) call must handle scenarios with no data for the given block_id.

15-15: Ohayo sensei, good import addition of RpcModulesList and DEFAULT_RPC_MAX_PROOF_KEYS.
This centralizes RPC configuration constants in one place.

117-122: Ohayo sensei, max_proof_keys can potentially grow large.
Validate if there should be upper-bound checks to avoid over-allocation or performance regressions.

132-133: Ohayo sensei, default values for http_modules and max_proof_keys are well-chosen.
This ensures consistent behavior straight out of the box.

Also applies to: 135-135

398-402: Ohayo sensei, default_proof_keys() is a tidy way to unify defaults.
This function fosters maintainable code in case the default value changes in the future.

13-13: Ohayo sensei, centralized imports for state-related traits.
Looks consistent with the broader design pattern shift.

269-281: Ohayo sensei, StateRootProvider trait is unimplemented here.
If future expansions require state roots, modularizing a partial implementation or mock might help.

42-42: Ohayo sensei, dropping StateRootProvider from imports.
Verify that all references to this trait have been safely removed to avoid broken references.

4-6: Ohayo sensei! Let's verify the new submodule configuration~

The piltover submodule addition looks properly configured, but let's make sure everything is set up correctly!

#!/bin/bash
# Verify submodule accessibility and integration
echo "Checking submodule URL accessibility..."
git ls-remote https://github.com/cartridge-gg/piltover.git > /dev/null

# Check if submodule is referenced in other files
echo "Checking submodule usage..."
rg -l "piltover" --type rust

#!/bin/bash
# Let's check the actual usage of piltover in the files
echo "Checking piltover usage in core files..."
rg "piltover" crates/saya/core/src/dojo_os/piltover.rs -A 5

echo "\nChecking initialization usage..."
rg "piltover" bin/katana/src/cli/init/mod.rs -A 5

11-13: Sugoi work on the workspace dependencies, sensei! ✨

The migration to workspace-level dependency management is clean and follows Rust best practices.

12-15: Konnichiwa! Let's check the dependency configuration~

The workspace dependency updates look great! However, I noticed serde is both in the workspace dependencies and cargo-udeps ignore list.

#!/bin/bash
# Verify serde usage in the codebase
echo "Checking direct serde derive usage..."
ast-grep --pattern 'derive($$$, Serialize, $$$)' || ast-grep --pattern 'derive($$$, Deserialize, $$$)'

echo "Checking serde attribute usage..."
rg '#\[serde' --type rust

20-23: Ohayo sensei! Please verify the dependency configuration.

The switch to a specific branch kariy/indexmap from the dojoengine fork needs careful consideration:

1. Using a specific branch rather than a tagged release could lead to stability issues
2. The repository change from madara-alliance to dojoengine is significant

Let's check the branch status:

16-16: LGTM! The trie dependency addition looks good, sensei!

The addition of katana-trie as a workspace dependency aligns well with the state management refactoring objectives.

10-14: Ohayo! New workspace dependencies look good, sensei! 🎋

The addition of katana-cairo and katana-primitives aligns well with the state management refactoring objectives.

37-39: Nice testing setup enhancement, sensei! 🎯

The addition of proptest and rstest will improve the testing capabilities. Moving starknet to dev-dependencies is a good architectural decision that reduces production dependencies.

12-12: Consider making katana-trie optional, sensei! 🤔

The katana-trie addition aligns with the state management refactoring. However, other components like blockifier and starknet are marked as optional. Should we consider making katana-trie optional as well for consistency?

Let's check how other crates use this dependency:

36-39: Dev dependencies are well chosen, sensei!

The addition of testing-related dependencies with workspace versioning will help maintain consistency across the project.

Line range hint 20-34: Ohayo! Dependencies look well-structured, sensei!

The new dependencies align well with enhancing RPC capabilities. The consistent use of workspace versioning is a good practice.

Let's verify the usage of these new dependencies:

#!/bin/bash
# Check if the new dependencies are actually used in the codebase
for dep in "metrics" "serde_json" "starknet" "thiserror" "tokio" "tower" "tower-http" "tracing" "url"; do
    echo "Checking usage of $dep..."
    rg --type rust "use.*$dep|extern.*$dep" crates/katana/rpc/
done

Line range hint 38-44: Optional dependencies are well organized!

The modular approach with optional dependencies allows for flexible feature selection.

Line range hint 28-32: Ohayo! Consider the implications of full feature sets, sensei!

While using the "full" feature sets for tower and tower-http provides comprehensive functionality, it might increase binary size. Consider using specific features instead if you don't need all capabilities.

Let's check the impact:

Line range hint 2-114: Sierra program bytecode looks good, sensei!

The bytecode array contains valid hex values and follows the expected format.

Line range hint 115-119: Empty debug information may impact testing.

The debug information arrays are empty, which could make debugging test failures more difficult.

Would you like me to help generate meaningful debug information for type names, library functions, and user functions?

Line range hint 120-138: Entry points configuration is properly structured.

The EXTERNAL entry points are well-defined with proper selectors and function indices. The empty L1_HANDLER and CONSTRUCTOR arrays are appropriate for this test contract.

Line range hint 139-219: ABI definition is comprehensive and well-structured.

The ABI includes all necessary functions:

• validate_deploy
• validate_declare
• validate
• execute
  And includes proper struct definitions with correct types.

31-31: Import statement updated correctly, sensei!

The import statement properly includes the new StateProofProvider and StateRootProvider traits.
