Harden Java adapter identities and SootUp coverage - #3
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The change adds fingerprints to source-root metadata and generated-root JSON output. It also updates method-signature parsing, call classification, provider and framework fact identity, dynamic-feature evidence, fact validation, and provider-link filtering.
Source roots accept fingerprints, and the loader passes them into analysis context. Run metadata and JSON output include generated roots and their fields. The test checks fingerprint retention, and the documentation describes the handoff details.
Parse signatures and classify call edges src/main/java/com/projectlightpath/analysis/java/MethodSymbol.java, src/main/java/com/projectlightpath/analysis/java/SootUpBaseGraphProvider.java, src/test/java/com/projectlightpath/analysis/java/MethodSymbolTest.java, src/test/java/com/projectlightpath/analysis/java/SootUpBaseGraphProviderIntegrationTest.java
Method signatures are parsed into JVM descriptors. Call edges use call-site ServiceLoader detection and interface-dispatch classification, with certainty set to definite only for ordinary invokes. Tests cover descriptors, interface dispatch, and direct calls.
Disambiguate fact identities and evidence src/main/java/com/projectlightpath/analysis/java/DynamicFeature.java, src/main/java/com/projectlightpath/analysis/java/BoundedFrameworkModel.java, src/main/java/com/projectlightpath/analysis/java/ProviderFactNormalizer.java
Framework and provider fact IDs incorporate additional candidate, signature, source, or feature identity when legacy IDs are not unique. Dynamic-feature evidence includes available source-line and target-descriptor data. Reflection, dynamic-proxy, and proxy-dispatch edges receive unresolved certainty.
Validate fact IDs and filter provider links src/main/java/com/projectlightpath/analysis/java/SemanticCallFacts.java, src/main/java/com/projectlightpath/analysis/java/JavaAnalysisAdapter.java
Fact collection rejects duplicate IDs within a relationship set. Provider identity matching and link creation exclude providers with unresolved certainty.

project-lightpath/java-analysis-adapter#1: Adds the AnalysisContext handoff and provenance flow that this change extends with generated-root metadata and fingerprints.
project-lightpath/java-analysis-adapter#2: Adds framework facts and provider links that this change updates with more specific fact IDs and unresolved-provider filtering.
Security architecture risk: Moderate · up to 714d7
The change improves provenance and uncertainty handling, but an identifier can move between unrelated calls and silently misdirect an analysis link. The visible impact is bounded to analysis output; downstream distribution and trust policies are not documented.
Retained concerns
Medium · architecture · inferred: Normalized descriptors make unrelated calls share the provider ID seed. The first call receives the unsuffixed ID, so adding a lexically earlier same-shaped call can transfer a metadata-referenced ID to another observation. Explicit derivedFrom references are checked for existence and certainty, not target identity, allowing a framework fact to retain a link to the wrong provider observation. This weakens the provenance contract even though every emitted ID is unique.
Security review details
Security Blast Radius
inferred — The demonstrated scope is the selected repository's analysis result and its provenance links. The inspected command writes a caller-selected local output file. The documentation explicitly excludes vulnerability policy and production orchestration guarantees, so service-wide, tenant-wide, or privileged downstream effects are not established.
Security Findings and Attack Paths
inferred — A source author can introduce another call with the same caller/callee descriptor shapes and line number. If it sorts before an existing call, it receives that call's unsuffixed ID. Metadata carrying that ID can then link to the new observation without target revalidation. This is an analysis-provenance integrity path; downstream security-policy impact is unproven.
Trust Boundaries and Controls
observed — Loaded roots remain subject to normalized absolute-path, repository-containment, existence, and inclusion checks. Preserved fingerprints are supplied provenance assertions, not newly introduced authorization or independently verified freshness controls.
Resilience and Maintainability Implications
inferred — Normalization and validation build invocation-local collections, and invalid fact sets fail before a SemanticCallFacts result is returned. This contains semantic-validation failures within an analysis invocation. Source inspection, rather than runtime concurrency or interruption testing, supports this conclusion.
Hardening Proposals
proposed — Derive every provider ID from the complete observation identity, including owner and method names, rather than reserving the incomplete seed for the first collision. Validate explicit metadata references against the intended provider target before emitting provenance links.

Edges with the same descriptors tie in the current sort. If they also share a line number, their provider IDs can change with the HashSet iteration order. An explicit providerFactId can then link to a different edge.

Update the `result.sort` ordering in `SootUpBaseGraphProvider` to use the full
identity of each call edge, including caller and callee identity, line number,

tie, so provider IDs remain deterministic regardless of `HashSet` iteration
order.
The code calls scanner.methodSource(...) for every call edge. The result is used only when call.getLineNumber() <= 0. methodSource looks up the source file, filters the executable methods, and extracts the method body. On large graphs this adds avoidable work per edge. Move the call into the nonpositive-line branch.

Include the method signature in injection fact IDs.
If two annotated overloads inject the same named parameter and candidate, their fallback IDs are identical. For example, set(Service service) and set(Service service, Other other) collide. The new duplicate-ID check then aborts analysis. Include the enclosing method signature in the fallback identity.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
injectionCounts counts parameters, not injection sites, and omits the package.
uniqueInjectionSite is true only if the simple type name has exactly one injection parameter in total. This is stricter than the name suggests, but it is safe. It only withholds the legacy ID.
Two types with the same simple name in different packages are counted together. This only withholds legacy IDs, so no collision results. The behavior is consistent with the uniqueSimpleType checks. No change is required. Consider renaming the variable to injectionParameterCounts to match its meaning.
108-112: Trivial · Functional Correctness · Low value
Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Source-based ServiceLoader detection can misclassify calls in the nonpositive-line fallback.
When call.getLineNumber() is not positive, the code checks whether the whole caller method body contains ServiceLoader.load. Every call edge from that method then becomes service_loader with POSSIBLE certainty. This includes unrelated calls in the same method that have no line information.
This is a narrow edge case. The effect is lower certainty on some calls. The previous code had a similar whole-source risk. Consider restricting the fallback to callee owners or names that relate to ServiceLoader.
