# EPF Week 7

This week I focused on pushing the FOCIL implementation towards completion and tried around running some tests. Parallelly, I continued progressing on the Pureth side, specifically SSZ transactions and early log reform testing.

## FOCIL Updates

### Technical Work

* Completed integration of the two main parts of the FOCIL implementation (IL logic + validator changes).
* Began writing initial unit and integration tests for FOCIL.

### Status

The FOCIL draft is now at a stage where correctness validation is possible. Testing coverage is the main focus before moving further.

## Pureth Updates

### Development Progress

* Extended EELS tests to cover SSZ transaction encoding/decoding.
* Started building scaffolding for log reform testing (2D log index).
* Identified gaps that will need patching or workarounds.
* Implemented the ssz structs and tried to perform the roundtests for the decoding and encoding

# EPF Week 8

This week was mostly about stabilizing and testing: The SSZ work in Pureth started yielding first results.

## Pureth Updates

### Development Progress

* Completed first working test cases for SSZ transactions in EELS.
* Expanded test suite to include validation of SSZ receipts, including log extraction and encoding compliance.
* Set up Nimbus-EL fork . Waiting for some chanegs in the internal testing framework in nimbus to continue the work
* Initial exploration of 2D logs translated into draft test scenarios.(maping out the testcase,edge cases and how the rollback would work)

## Upcoming Goals (Week 9)

* Run broader FOCIL test scenarios and edge-case analysis.
* Solidify EELS SSZ tests and sync findings with Nimbus implementation.
* Extend receipt and log-related SSZ test coverage.
* Start documenting a unified testing plan for Pureth changes across EELS + Nimbus.
