WalkthroughBit.Butil now supports dependency-aware JavaScript bundle trimming and lazy module loading. The change adds build and publish integration, runtime configuration, browser-global namespace initialization, consumer documentation, samples, automated validation, and MSTest migration.

Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR changes JavaScript bundling, trimming, and lazy loading, but the current head still has failure paths that can publish incomplete assets, break lazy imports in deployed applications, or silently report an invalid bundle as successful.

107-114: 🩺 Stability & Availability | 🔵 Trivial | 💤 Low valueConsider a separator in
concatto make chunk concatenation independent of the minifier's output.Chunks are joined with an empty string. Correctness relies on each minified chunk ending with a statement terminator. esbuild emits the trailing
;for the IIFE statement today, so the current output is valid. A future esbuild version or option change that drops the terminator would make chunk N and chunk N+1 parse as a single call expression, and the bundle would break at runtime rather than at build time.Joining with
'\n'or';'removes the dependency on that behavior. Bothbit-butil.jsand the publish-time trimmed bundle use this same function, so the byte-for-byte equivalence the docs promise is preserved either way.♻️ Proposed change
-const concat = moduleNames => moduleNames.map(name => chunks.get(name)).join(''); +const concat = moduleNames => moduleNames.map(name => chunks.get(name).trimEnd()).join('\n') + '\n';Note: the C# side concatenates chunk files without a separator in
ButilScriptBundler.WriteBundle. If you changeconcat, add the same separator there so the two assembling paths stay byte-identical.🤖 Prompt for AI Agents

72-78: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueDependency discovery scans raw source, so comments and string literals create dependency edges.
The regex at line 73 runs over the whole
.tsfile text. Abutil.<name>reference inside a comment or a string literal counts as a real dependency. An extra edge normally only enlarges a lazy module file. However, if two modules mention each other only in comments,ordered()at line 88 reports a circular dependency and fails the build with a message that points at code which does not exist.Strip line and block comments before matching, or document the constraint next to the regex so a future comment does not break the build.

In `@src/Butil/Bit.Butil.Build/Bit.Butil.Build.csproj`:
- Around line 17-27: The Bit.Butil.Build project currently excludes runtime
assets for its MSBuild task dependencies, preventing full-framework MSBuild from
loading version 8 assemblies. Update the project configuration and packaging so
System.Reflection.Metadata and System.Collections.Immutable runtime dependencies
are bundled under tasks/, or align package references with supported MSBuild
hosts; verify loading through a full-framework consumer publish.
In `@src/Butil/Bit.Butil.Demo/Client/Pages/GettingStartedPage.razor`:
- Around line 70-87: Update GettingStartedPage.razor’s lazy-script guidance to
state that C#-only LazyScripts requires BitButilIncludeScriptModules=true,
recommend BitButilLazyScripts=true when possible, and ensure module imports have
published assets; update README.md lines 302-317 to state that default C#
runtime configuration publishes the bundle but not module files, and bundled
mode requires the bit-butil.js script tag.
In `@src/Butil/Samples/Bit.Butil.Samples.Web/Program.cs`:
- Around line 17-26: Update the startup query parsing in Program.cs and
wwwroot/index.html (Program.cs lines 17-26; wwwroot/index.html lines 17-23) to
enable lazy scripts only when the parsed lazy query parameter has the exact
value "1". Replace substring or key-presence checks with the same
key-and-exact-value predicate in both startup files, preserving normal behavior
for all other values.

Inline comments:
In `@src/Butil/Bit.Butil.Build/UserStringHeap.cs`:
- Around line 110-127: Update the `#US` bounds validation in the stream-scanning
method to avoid overflow from metadata + offset + size: first ensure the
nonnegative offset does not exceed the remaining image space, then ensure size
fits within the space remaining after that offset. Preserve Invalid(path, ...)
for malformed bounds and only construct the Heap after both checks pass.
In `@src/Butil/Bit.Butil.Demo/Client/Pages/RenderModesPage.razor`:
- Line 158: Update the BitButil.UseBundledScripts API description to clarify
that it changes runtime loading mode but cannot restore a bundle excluded at
publish time by BitButilLazyScripts=true; instruct callers to include and load
bit-butil.js before selecting bundled mode.
In `@src/Butil/Bit.Butil/buildTransitive/Bit.Butil.targets`:
- Around line 181-209: Update the _BitButilAssembleTrimmedBundle target to run
after ILLink by adding the appropriate target dependency, ensuring
TrimButilScripts reads the current linked Bit.Butil assembly during incremental
publish.
In `@src/Butil/Bit.Butil/Internals/ButilScriptLoader.cs`:
- Around line 51-57: Update TryGetModule to reset module before validation and
accept a module name only when every character is a letter, digit, or
underscore. Reject punctuation and path separators before returning true,
preserving the existing prefix and delimiter checks.
In
`@src/Butil/tests/Bit.Butil.Tests.E2E/Infrastructure/verify-interop-contract.mjs`:
- Around line 100-108: Update resolves to verify that current is an object or
function before applying the in operator; return false for primitive
intermediate values while preserving traversal for valid objects and functions.
In `@src/Butil/tests/Bit.Butil.Tests.Manual/ScriptBundling.cs`:
- Around line 561-573: Update the process-output handling around
StandardOutput.ReadToEnd and StandardError.ReadToEnd to start both reads
concurrently, then await both read tasks together with the existing 60-second
timeout before evaluating the result. Preserve the timeout cleanup via
process.Kill(entireProcessTree: true) and the existing failure reporting.
In `@src/Butil/tests/Bit.Butil.Tests.Manual/verify-bundle.mjs`:
- Around line 126-129: Update the sentinel loop in verify-bundle.mjs to process
only non-version keys whose namespace values are objects, and track those
eligible entries as markable. Apply the later reset/re-registration check only
to markable namespaces so malformed values are skipped without throwing or
producing misleading reports.
- Line 36: Update the label construction in the scripts.map expression to split
each script path on both forward-slash and backslash separators, while
preserving the existing basename extraction and joined label format.

src/Butil/Samples/Bit.Butil.Samples.Web/Program.cs lines 24-27 and
src/Butil/Samples/Bit.Butil.Samples.Web/wwwroot/index.html lines 21-24: parse
decoded lazy parameters instead of matching raw query segments, and apply the
same shared duplicate-key policy in both startup paths before enabling or
omitting the bundle.

Nitpick comments:
In `@src/Butil/Bit.Butil.Build/ButilScriptBundler.cs`:
- Around line 75-106: Update ReadManifest to validate dependency-first ordering
while parsing the manifest: when processing each module in the existing order
loop, reject any dependency that has not already appeared in the manifest, while
retaining the separate check for unknown module names and the existing
ButilScriptManifest construction.
In `@src/Butil/tests/Bit.Butil.Tests.Manual/verify-bundle.mjs`:
- Around line 54-76: Share the duplicated createSandbox factory between both
validation scripts. In src/Butil/tests/Bit.Butil.Tests.Manual/verify-bundle.mjs
lines 54-76, remove the local createSandbox definition and import it from a

435-436: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value
IndexOf(chunk)on the whole bundle is quadratic in the number of modules.The loop searches the full bundle text twice for each chunk, so the work grows with modules × bundle size. With ~65 modules the cost is tolerable today. If the check becomes slow, record each chunk's offset once with a single forward scan instead.
