Run this single PowerShell command:

powershell

powershell.exe -NoProfile -ExecutionPolicy Bypass -STA -File "C:\Users\PC\Downloads\LeanSERP-Studio\LeanSERP-Studio-GUI.ps1"

To open it without keeping a visible PowerShell window:

powershell

Start-Process -FilePath "powershell.exe" -ArgumentList '-NoProfile -ExecutionPolicy Bypass -STA -WindowStyle Hidden -File "C:\Users\PC\Downloads\LeanSERP-Studio\LeanSERP-Studio-GUI.ps1"' -WindowStyle Hidden

Use the reliable engine for large builds

Run important builds directly in PowerShell instead of through the GUI:

powershell

powershell.exe -NoProfile -ExecutionPolicy Bypass -File "C:\Users\PC\Downloads\LeanSERP-Studio\LeanSERP-Studio.ps1" -InputFile "C:\Users\PC\Downloads\1.txt" -OutputDirectory "C:\Users\PC\Downloads\LeanSERP-Output" -ChunkSize 250000 -KeepUnderscores

Run the launcher with: powershell.exe -NoProfile -ExecutionPolicy Bypass -STA -File "C:\Users\PC\Downloads\LeanSERP-Studio\Start-LeanSERP-Build.ps1"

To test interruption safely, press Ctrl+C in that build console after Created chunk 1 appears.

safest production workflow is:

Use Start-LeanSERP-Build.ps1.

Watch progress in its dedicated console.

Press Ctrl+C to request interruption.

Verify no builder process remains.

Remove only incomplete build directories.

Use the GUI for selecting files, reports, and small builds until the polling-based runner integration is tested.

2026.07.22 18:47: "One older process, PID 7208, was still shown earlier. Since the restarted build is now running, do not terminate PowerShell processes blindly. After this build completes, verify no runner or builder remains:

Can you understand this? What do you understand?

Yes. I understand that you are building two related but separate applications:

1. LeanSERP Studio

A standalone Windows application, currently based on PowerShell and WinForms. It should:

Use no active CPU, RAM, GPU, or network resources when closed.

Normalize, sort, deduplicate, inspect, and package very large domain or URL lists.

Keep processing work outside Firefox.

Produce compact files that LeanSERP Filter can import.

Support live progress, stopping, reports, SHA-256 verification, and bounded-memory processing.

You have two processing modes:

Label mode for inputs such as *://*.example/* or example.

URL mode for full hostnames and URLs, using the Public Suffix List to extract main labels.

2. LeanSERP Filter

A lightweight Firefox extension that will eventually:

Import the package produced by Studio.

Filter search results using exact hostname and complete-label matching.

Respect Public Suffix List boundaries.

Allow explicitly approved PSL overrides such as gov, nhs, and hluttaw.

Avoid substring matches: gov matches the complete label gov, but not mygov.

Include optional SERP simplification and resource-saving features.

Its package-import functionality has not yet been implemented.

What has been completed

Stable PowerShell label mode

The ordinary label builder works and has been tested with:

Streaming input.

Bounded sorted chunks.

Global sorting and deduplication.

BOM cleanup.

Rejection reports.

Metadata and SHA-256 verification.

Multiple files.

Live GUI logging.

Process-tree stopping and cleanup.

PowerShell URL mode

The URL normalizer works correctly but is extremely slow. On the 1,456,946-line test:

Metric Result

Accepted lines 1,455,897

Rejected lines 1,049

Unique labels 1,226,659

Exact hosts 1

PSL overrides 3

Runtime About 6,925 seconds

Its output is the correctness reference.

Compiled C# mode

The compiled normalizer processed the same 1,456,946 lines in 12.219 seconds, roughly 567 times faster.

Before applying approved rules, it produced:

1,226,658 labels.

One missing label: hluttaw.

24 extra PSL-only rejections.

The separate ApplyApprovedOverrides.exe then:

Loaded the three approved overrides.

Used two of them in that dataset.

Added the missing hluttaw label.

Used one approved exact hostname.

Produced 1,226,659 final labels.

Produced the exact same label hash as the PowerShell reference:

text

4ccb08039ea029c081f4b52200e855ddb031b7a1b491b90025d6fa3af2ca5cb0

That proves the two-stage compiled pipeline can reproduce the reference labels.txt for the benchmark.

Current compiled workflow

powershell

2026.07.27 19:41: "The compiled normalizer removes http:// and https:// before extracting the hostname and main label.

Input Resulting label

[example.com](http://example.com/page) example

[example.com](https://www.example.com?q=1) example

[www54.example.co.uk](https://www54.example.co.uk/path) example

[subdomain.wikipedia.org](http://subdomain.wikipedia.org) wikipedia

It also removes:

Leading www, www1, www54, etc. when Remove www-number labels is checked.

Paths, queries, and fragments, such as /page, ?q=1, and #section.

Ports and credentials, where supported.

Public suffixes such as com, co.uk, and org.

The original source file is not modified. These transformations apply only while generating the normalized package. Exact approved hosts and PSL overrides remain in their separate rule files.",

2026-07-27 19:44:"The compiled normalizer creates two diagnostic reports inside each compiled-build-* directory:

File Purpose

rejected-lines.tsv Records the rejection reason, source file, line number, and original input.

public-suffix-only.tsv Records hostnames rejected because the complete hostname is a Public Suffix List entry.

For example:

text

reason source line originalpublic-suffix-only ...\input.txt 113 amplifyapp.cominvalid-url ...\input.txt 250 https://[invalidempty-comment-or-directive ...\input.txt 400 #comment

The public-suffix report contains:

text

hostname publicSuffix source linegithub.io github.io ...\input.txt 1234cloudfront.net cloudfront.net ...\input.txt 5678

Important package distinction

These reports currently remain in the intermediate compiled build, such as:

text

C:\Users\PC\Downloads\LeanSERP-Compiled-Output\compiled-build-...\rejected-lines.tsvC:\Users\PC\Downloads\LeanSERP-Compiled-Output\compiled-build-...\public-suffix-only.tsv

Your final unified package currently includes rejected-lines.tsv, but the GUI pipeline does not appear to pass the compiled rejection report to New-LeanSerpPackage.ps1. Therefore, the final package's rejected-lines.tsv is probably empty. public-suffix-only.tsv is not currently part of the unified package manifest.

You can inspect the latest compiled rejection reasons with:

powershell

$root = "C:\Users\PC\Downloads\LeanSERP-Compiled-Output"$build = Get-ChildItem -LiteralPath $root -Directory | Where-Object { $_.Name -like "compiled-build-*" } | Sort-Object LastWriteTime -Descending | Select-Object -First 1if ($null -eq $build) { throw "No compiled build was found."}$rejections = Join-Path $build.FullName "rejected-lines.tsv"if (-not (Test-Path -LiteralPath $rejections -PathType Leaf)) { throw "The rejection report was not found: $rejections"}$rows = @(Import-Csv -LiteralPath $rejections -Delimiter "`t")Write-Host "Build: $($build.FullName)"Write-Host "Rejected rows: $($rows.Count)"$rows | Group-Object -Property reason | Sort-Object -Property Count -Descending | Select-Object Count, Name | Format-Table -AutoSize

To view the first 30 rejected entries:

powershell

$rows | Select-Object -First 30 reason, source, line, original | Format-Table -Wrap -AutoSize

The next Studio improvement should copy both diagnostic files into the unified package as review-only files, without activating either one in LeanSERP Filter.",
