Self check:

File system (src/fs)
+6 create.js:

File creates and filled successfully

Fails with error if file already created
+10 copy.js implemented properly

Successfully copies folder with its content (including subfoler with files in it, recursively)
+10 rename.js implemented properly

Successfully renames file && proper handling existing destination/missing source
+6 delete.js implemented properly
Removing file using function fs.unlink, proper handling of missing file to delete
+6 list.js implemented properly

Proper listed files from 'files' folder using fs.readdir function, and handle missing directory.
+6 read.js implemented properly

Read of file using fs.readFile function
Command line interface(src/cli)
+6 env.js implemented properly

Properly handled environment variables. Output contains only entries started with "RSS". Values are separated with semicolon._
+6 args.js implemented properly

Properly handled console arguments. Values are separated with coma.
Modules(src/modules)
+20 cjsToEsm.cjs refactored properly
require functions replaced with import, json read with 'await import' instead of require function, previously implemented with JSON.parse, which returns json object directly (without 'default' property) (see the comments). Exported objects with esm 'export' statement
Hash (src/hash)
+10 calcHash.js implemented properly
Function implemented using crypto.createHash('sha256') function. Initially missed "using Streams API", so later (28.04) reworked with streams and piping.
Streams (src/streams)
+10 read.js implemented properly

Successfully read file using streams and piping.
+10 write.js implemented properly
Easiest implementation in two lines.
+10 transform.js implemented properly

Implemented transformation using Transform object.
Zlib (src/zip)
+10 compress.js implemented properly
+10 decompress.js implemented properly
Nothing to comment, just implementation of compressing/decompressing module using streams and piping
Worker Threads (src/wt)
+10 worker.js implemented properly
Added response from worker to main thread using parentPort with results of nthFibonacci with load from workerData
+30 main.js implemented properly

Implemented method to perform per-thread calculations of Fibonacci numbers for i+10 iterations, ordered with ascending order, since creating promises synchronously, link
Child Processes (src/cp)
+10 spawns child process
+10 child process stdin receives input from master process stdin
+10 child process stdout sends data to master process stdout

Implemented function using child_process.fork method. Piped child and parent stdin/stdout channels

Result:

Basic scope: 136/136
Advanced scope: 70/70
Forfeits: 0
