Core stops carrying the memex/ folder. Everything in it belonged to the portal hosts, which live in MeshWeaver.Plugins. This is the DELETE half. It stays a draft until Systemorph/MeshWeaver.Plugins#4333, the addition half, has merged, because core CD publishes the hosts from Plugins main at its head.

Deleted

• memex/MeshModulesPublish.targets, which Plugins now carries as src/MeshModulesPublish.targets.
• memex/aspire/Memex.Portal.ServiceDefaults, which Plugins now carries as src/Memex.Portal.ServiceDefaults.
• memex/Directory.Build.props, which only served those two.
• The MeshWeaver.slnx folder entries for memex/.
• MeshWeaver.Hosting.Test's reference to ServiceDefaults, and AnArbitraryUrlFetcherGivingUpIsAWarningTest, which moved to Plugins' Memex.Portal.Shared.Test.
• .aspire/settings.json and two .gitignore lines. All three pointed at memex/aspire/ paths core no longer has, including the AppHost.
• memex from the scanned roots of 20 source guards. NoLiteralNulInSourceGuard refused the now-empty root, which is its job; the other 19 skipped it silently.
• Roslynator: five PackageVersion pins no core project restores (measured from every obj/project.assets.json after a full solution restore). Their only use was a PackageReference Update= block in MeshWeaver.Layout.csproj that matched no Include. Every satellite that runs Roslynator pins it in its own list, and Plugins does not use it.

Kept: the reader side of the module layout (ImageModuleSeed, PlatformShippedAssemblies, MeshBuilder.ResolveModulePath). Their comments now name the Plugins paths.

Docs:

• CoreCarriesNoGuiTechnology marks memex/ as moved.
• CarvingProjectsOutOfCore records the second package pass.
• Nine pages now name the new paths.

Verified locally, Release with -warnaserror:

• MeshWeaver.slnx restores clean.
• Compiler, PluginCatalog, Layout, Hosting.Test, Documentation.Test, Graph.Test and Hosting.Orleans.Test build with 0 warnings and 0 errors.
• MeshWeaver.Documentation.Test passes 878 of 878.
• InlineSvgEmissionBackplateGuard and PackableProjectReadmeTest pass 13 of 13.
• GrainActivationSiteRatchetGuard passes 3 of 3.

Satellite-pins: Roslynator.Analyzers — checked MeshWeaver.Plugins main: no PackageReference (Include or Update) to it in any csproj, props or targets file; no core project restores it either, so the pin governed nothing.

🔵 Needs a closer look

Plugins PR #4333 returned 404, so preservation of the deleted infrastructure and tests, and the required merge ordering, remain unverified.

No open issues 🎉

_{Review effort: Balanced}

Review re-requested on the maintainer's instruction (Copilot had refused for requester quota, review 5666576141); review-waived was briefly applied and removed again.

🔵 Needs a closer look

Plugins #4333 returned 404, so human review must confirm preservation of the relocated implementation and host/build wiring, and that the addition half has merged before this deletion lands.

No open issues 🎉

🔵 Needs a closer look

The required companion PR, Systemorph/MeshWeaver.Plugins#4333, returned 404, preventing verification that the replacement files, updated host imports, and relocated tests are on the default branch before these deletions land.
