Why

Maintainer, 2026-10-03: "why are ci run so long? should only run test of delta plugin not all" … "run only affected parts … incl dependencies".

MeshWeaver.Plugins#2734 changed two files under src/MeshWeaver.Blazor/wwwroot/lib/monaco-editor/ (the vendored Monaco bundle and its versions.json). node-repo-project-scope.py selected 14 portal-host suites for it (run 37124132005), four ~22-minute Blazor legs among them, because:

1. every entry whose compiled closure contains src/MeshWeaver.Blazor was selected, although no compiler reads a wwwroot/ file and MeshWeaver.Blazor is image-shipped, so no module bundle carries it either;
2. linked includes were cut to their literal directory: ../MeshWeaver.Blazor/**/*.razor (Blazor.Views.Test) read as "all of src/MeshWeaver.Blazor";
3. inputs are prefixes only, so a suite that censuses src/**/*.cs had to declare src/.

What changed (.github/scripts/node-repo-project-scope.py)

• An input or a linked include holding * or ? is a glob (input_covers): **/ spans zero or more directories, ** anything, */? stay inside a segment. A ;-separated Include is read as each pattern. A pattern without a wildcard is the prefix it always was.
• A static web asset (<project>/wwwroot/…) of a project the caller declares image-shipped (project-closure.py → platform_shipped) reaches only the owner, its sibling <owner>.Test, and entries that link or declare it. A caller without that helper keeps the plain closure rule (the loud direction).
• Doc: Architecture/BuildScopeNarrowing.md, section Separate compiled validation from content publication.

Self-test: 29 assertions (11 new), each new rule with its negative control (an asset BESIDE a source change in the owner still takes the closure; an asset of a non-shipped project still takes the closure; a wwwrootish/ folder is a compile input).

Measured against the Plugins tree (dry run of this selector + Plugins' declared selector)

PR	before	after	reconcile
#2739 (Store/Plugin/Test/*.cs)	1 host suite	1 (Memex.Hosts.Test)	agrees
#2734 (Monaco wwwroot/)	13 host suites	2 (Memex.Hosts.Test, Memex.Portal.Gui.Test — it links the bundle)	agrees
#2744 (Hosting/Deployment/{Source,Test}, a page)	2	2 (Memex.Hosts.Test, Fleet.Control.Test — it compiles that Source)	agrees

The paired Plugins change (declared selector + policy globs) declares Core-ref to this PR: until this reaches a sealed set, Plugins' reconcile would be RED on an asset-only diff (core selecting suites the declaration no longer names).

Nothing a running instance serves changes; no recycle is owed.
