WalkthroughThe PR adds publish-time Bit.Butil script trimming from ILLink data, assembly scans, and explicit module names. It introduces managed PE and metadata readers, updates MSBuild integration, and adds a server-backed documentation search index with compressed delivery, ranked client search, and endpoint tests. ChangesScript trimming reachability
Documentation search index
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔵 Low · up to This PR adds publish-time script trimming and server-backed documentation search. It has bounded merge-readiness risks: some hyphenated or underscored searches may rank inaccurately, a bundling test may report false drift, and manifest names are not constrained to safe path segments during publishing. The changes remain mergeable with explicit owner awareness or follow-up; no blocking security or availability impact is supported. Sequence Diagram(s)sequenceDiagram

Full details: Linked Issues checkExplanation The PR makes PublishTrimmed optional, adds explicit module selection through ExplicitModules and BitButilScriptModule, and adds TypeReferences and TypeNames scan modes for used-module detection [ Full details: Out of Scope Changes checkExplanation The PR includes an unrelated documentation search feature, including DocsSearchIndex, DocsController, DocsContentIndex, SearchBox changes, CSS changes, and DocsSearchIndexTests. These changes do not support Butil trimming objectives. Full details: Docstring CoverageExplanation Docstring coverage is 56.30% which is insufficient. The required threshold is 80.00%.

Inline comments:
In `@src/Butil/Bit.Butil.Build/ButilConsumerScan.cs`:
- Line 84: Move the Path.GetFullPath call in Scan into the existing guarded try
block so malformed paths are handled by the documented unreadable-entry path
instead of escaping. Preserve the deduplication behavior by continuing for paths
already present in seen, without recording them as skipped.
In `@src/Butil/Bit.Butil.Build/MethodBody.cs`:
- Around line 52-76: Add opcode 0x8C (box) to the one-byte token/operand
initialization alongside the other four-byte type-token opcodes, setting
OneByteOperand to 4 and OneByteToken to true. Leave the existing two-byte opcode
table unchanged.
In `@src/Butil/Bit.Butil.Demo/Client/Pages/GettingStartedPage.razor`:
- Around line 74-83: Update the comments immediately above the two BitButil
PropertyGroup blocks to explicitly state that the blocks are alternatives,
adding one clarifying word to each comment without changing the MSBuild
settings.
In `@src/Butil/Bit.Butil.Demo/Client/Shared/SearchBox.razor`:
- Line 59: Update the result-row key near the existing hit.Url key so every
sibling receives a unique value, combining the row index with hit.Url while
preserving URL context. Ensure the key remains stable for the row-rendering loop
and prevents duplicate keys when API-member hits share a URL.
In `@src/Butil/Bit.Butil.Demo/Server/Controllers/DocsController.cs`:
- Around line 38-44: Update the header handling in DocsController to use
Request.GetTypedHeaders() for both conditional requests and content negotiation:
match valid comma-separated and weak If-None-Match entity tags, and select gzip
only when its Accept-Encoding Quality permits it (not when q=0). Preserve the
existing 304 response and gzip behavior for headers that explicitly allow them.
In `@src/Butil/Bit.Butil.Demo/Server/Services/ButilSetupGuide.cs`:
- Around line 279-289: Update checklist step 2 in ButilSetupGuide so its
introductory switch count matches all switches described, including
BitButilTrimScripts, BitButilScriptScan, BitButilScriptModule, and
BitButilIncludeScriptModules; also add the missing connective in the sentence
beginning “Publishing WITHOUT trimming” so the condition reads grammatically.
