 ## Execution Log
 | Date (UTC) | Update | Owner |
 | --- | --- | --- |
+| 2025-12-06 | Completed task 24 (Wave E/CLI Tests): Added `Create_ExposesBunInspectAndResolveCommands` to CommandFactoryTests.cs. Added 4 Bun tests to CommandHandlersTests.cs: `HandleBunInspectAsync_WritesJson`, `HandleBunResolveAsync_RendersPackages`, `HandleBunResolveAsync_WritesJson`, `HandleBunResolveAsync_NotifiesWhenInventoryMissing`. Added BunInventory/BunInventoryException/LastBunPackagesScanId properties and GetBunPackagesAsync to StubBackendClient. Added helper methods CreateBunWorkspace, CreateBunPackageItem, CreateBunInventory. CLI test project has pre-existing build errors (MigrationModuleRegistry.cs) unrelated to Bun changes. Sprint 0139 now COMPLETE. | Implementer |
+| 2025-12-06 | Completed tasks 28-29 (Wave F/Docs): Updated `docs/modules/scanner/architecture.md` with Bun analyzer coverage (project layout, language ecosystem section, Mongo collection, REST endpoint, config example). Created `docs/modules/scanner/bun-analyzer-gotchas.md` documenting 10 gotchas: isolated installs, .bun/ scanning, bun.lockb migration, JSONC format, multi-stage builds, npm ecosystem reuse, source detection, workspace handling, dev/prod filtering, evidence model. | Implementer |
+| 2025-12-06 | Completed tasks 25-27 (Wave E/WebService+Worker): Created Bun package inventory infrastructure following Ruby pattern. Added `BunPackageInventory.cs` (contract + IBunPackageInventoryStore + NullBunPackageInventoryStore), `BunPackageInventoryDocument.cs` (Mongo catalog), `BunPackageInventoryRepository.cs`, `BunPackageInventoryStore.cs`, `BunPackageInventoryBuilder.cs`. Updated `MongoCollectionProvider`, `ScannerStorageDefaults`, `ServiceCollectionExtensions`. Wired `IBunPackageInventoryStore` into `SurfaceManifestStageExecutor` with `PersistBunPackagesAsync`. Added Null fallback in Worker `Program.cs`. Created `BunContracts.cs` and `HandleBunPackagesAsync` endpoint in `ScanEndpoints.cs`. All Scanner library projects build successfully; Worker/WebService have pre-existing unrelated build errors. | Implementer |
+| 2025-12-06 | Completed tasks 22-23 (Wave E/CLI): Added `bun inspect` and `bun resolve` CLI verbs. Created `BuildBunCommand` in CommandFactory.cs, `HandleBunInspectAsync`/`HandleBunResolveAsync` handlers in CommandHandlers.cs, `BunInspectReport`/`BunResolveReport` classes, `BunPackageModels.cs` in Services/Models/Bun/, `GetBunPackagesAsync` in IBackendOperationsClient/BackendOperationsClient, and Bun metrics in CliMetrics. Added Bun analyzer project reference to CLI csproj. Bun analyzer builds successfully; CLI has pre-existing MigrationModuleRegistry build errors (unrelated). | Implementer |

+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2025-12-06 | Wave A complete: Created 5 foundation files (JavaDependencyDeclaration, JavaProjectMetadata, JavaPropertyResolver, SpdxLicenseNormalizer, JavaBuildFileDiscovery) | Claude |
+| 2025-12-06 | Wave B complete: Created 5 Gradle parsing files (GradlePropertiesParser, GradleGroovyParser, GradleKotlinParser, TomlParser, GradleVersionCatalogParser) | Claude |
+| 2025-12-06 | Wave C partial: Created 2 Maven files (MavenPomParser, MavenParentResolver) | Claude |
+| 2025-12-06 | Wave D partial: Created 3 detection files (ShadedJarDetector, OsgiBundleParser, VersionConflictDetector) | Claude |
+| 2025-12-06 | Build verified successful - all 15 new files compile | Claude |
+
+## Decisions & Risks
+- **Risk:** Gradle DSL is dynamic; regex-based parsing will miss complex patterns
+  - **Mitigation:** Focus on common patterns; emit `unresolvedDependency` for unparseable declarations; document limitations
+- **Risk:** Parent POMs may not be available locally (repository-only)
+  - **Mitigation:** Log warnings; continue with partial data; emit `parentUnresolved` metadata
+- **Risk:** BOM imports can create cycles
+  - **Mitigation:** Track visited BOMs; limit depth to 5 levels
+- **Risk:** Property resolution can have cycles
+  - **Mitigation:** Limit recursion to 10 levels; emit `unresolvedProperty` for cycles
+- **Decision:** Gradle lockfile still takes precedence over build.gradle when both exist
+- **Decision:** SPDX normalization starts with ~50 high-confidence mappings; expand based on telemetry
+- **Decision:** Shaded detection requires confidence score >= Medium to emit `shaded: true`
+
+## Next Checkpoints
+- Wave B completion: Gradle parsing functional
+- Wave C completion: Maven property resolution working
+- Wave D completion: All detection features implemented
+- Wave F completion: Full test coverage with golden fixtures

+# Bun Analyzer Developer Gotchas
+
+This document covers common pitfalls and considerations when working with the Bun analyzer.
+
+## 1. Isolated Installs Are Symlink-Heavy
+
+Bun's isolated linker (`bun install --linker isolated`) creates a flat store under `node_modules/.bun/` with symlinks for package resolution. This differs from the default hoisted layout.
+
+**Implications:**
+- The analyzer must traverse `node_modules/.bun/**/package.json` in addition to `node_modules/**/package.json`
+- Symlink safety guards are critical to prevent infinite loops and out-of-root traversal
+- Both logical and real paths are recorded in evidence for traceability
+- Performance guards (`MaxSymlinkDepth=10`, `MaxFilesPerRoot=50000`) are enforced
+
+**Testing:**
+- Use the `IsolatedLinkerInstallIsParsedAsync` test fixture to verify `.bun/` traversal
+- Use the `SymlinkSafetyIsEnforcedAsync` test fixture for symlink corner cases
+
+## 2. `node_modules/.bun/` Scanning Requirement
+
+Unlike Node.js, Bun may store packages entirely under `node_modules/.bun/` with only symlinks in the top-level `node_modules/`. If your scanner configuration excludes `.bun/` directories, you will miss dependencies.
+
+**Checklist:**
+- Ensure glob patterns include `.bun/` subdirectories
+- Do not filter out hidden directories in container scans
+- Verify evidence shows packages from both `node_modules/` and `node_modules/.bun/`
+
+## 3. `bun.lockb` Migration Path
+
+The binary lockfile (`bun.lockb`) format is undocumented and unstable. The analyzer treats it as **unsupported** and emits a remediation finding.
+
+**Migration command:**
+```bash
+bun install --save-text-lockfile
+```
+
+This generates `bun.lock` (JSONC text format) which the analyzer can parse.
+
+**WebService response:** When only `bun.lockb` is present:
+- The scan completes but reports unsupported status
+- Remediation guidance is included in findings
+- No package inventory is generated
+
+## 4. JSONC Lockfile Format
+
+`bun.lock` uses JSONC (JSON with Comments) format supporting:
+- Single-line comments (`// ...`)
+- Multi-line comments (`/* ... */`)
+- Trailing commas in arrays and objects
+
+**Parser considerations:**
+- The `BunLockParser` tolerates these JSONC features
+- Standard JSON parsers will fail on `bun.lock` files
+- Format may evolve with Bun releases; parser is intentionally tolerant
+
+## 5. Multi-Stage Build Implications
+
+In multi-stage Docker builds, the final image may contain only production artifacts without the lockfile or `node_modules/.bun/` directory.
+
+**Scanning strategies:**
+1. **Image scanning (recommended for production):** Scans the final image filesystem. Set `include_dev: false` to filter dev dependencies
+2. **Repository scanning:** Scans `bun.lock` from source. Includes all dependencies by default (`include_dev: true`)
+
+**Best practice:** Scan both the repository (for complete visibility) and production images (for runtime accuracy).
+
+## 6. npm Ecosystem Reuse
+
+Bun packages are npm packages. The analyzer:
+- Emits `pkg:npm/<name>@<version>` PURLs (same as Node analyzer)
+- Uses `ecosystem = npm` for vulnerability lookups
+- Adds `package_manager = bun` metadata for differentiation
+
+This means:
+- Vulnerability intelligence is shared with Node analyzer
+- VEX statements for npm packages apply to Bun
+- No separate Bun-specific advisory database is needed
+
+## 7. Source Detection in Lockfile
+
+`bun.lock` entries include source information that determines package type:
+
+| Source Pattern | Type | Example |
+|---------------|------|---------|
+| No source / default registry | `registry` | `lodash@4.17.21` |
+| `git+https://...` or `git://...` | `git` | VCS dependency |
+| `file:` or `link:` | `tarball` | Local package |
+| `workspace:` | `workspace` | Monorepo member |
+
+The analyzer records source type in evidence for provenance tracking.
+
+## 8. Workspace/Monorepo Handling
+
+Bun workspaces use a single `bun.lock` at the root with multiple `package.json` files in subdirectories.
+
+**Analyzer behavior:**
+- Discovers the root by presence of `bun.lock` + `package.json`
+- Traverses all `node_modules/` directories under the root
+- Deduplicates packages by `(name, version)` while accumulating occurrence paths
+- Records workspace member paths in metadata
+
+**Testing:** Use the `WorkspacesAreParsedAsync` test fixture.
+
+## 9. Dev/Prod Dependency Filtering
+
+The `include_dev` configuration option controls whether dev dependencies are included:
+
+| Context | Default `include_dev` | Rationale |
+|---------|----------------------|-----------|
+| Repository scan (lockfile-only) | `true` | Full visibility for developers |
+| Image scan (installed packages) | `true` | Packages are present regardless of intent |
+
+**Override:** Set `include_dev: false` in scan configuration to exclude dev dependencies from results.
+
+## 10. Evidence Model
+
+Each Bun package includes evidence with:
+- `source`: Where the package was found (`node_modules`, `bun.lock`, `node_modules/.bun`)
+- `locator`: File path to the evidence
+- `resolved`: The resolved URL from lockfile (if available)
+- `integrity`: SHA hash from lockfile (if available)
+- `sha256`: File hash for installed packages
+
+Evidence enables:
+- Tracing packages to their origin
+- Validating integrity
+- Explaining presence in SBOM
+
+## CLI Reference
+
+### Inspect local workspace
+```bash
+stellaops-cli bun inspect --root /path/to/project
+```
+
+### Resolve packages from scan
+```bash
+stellaops-cli bun resolve --scan-id <id>
+stellaops-cli bun resolve --digest sha256:<hash>
+stellaops-cli bun resolve --ref myregistry.io/myapp:latest
+```
+
+### Output formats
+```bash
+stellaops-cli bun inspect --format json > packages.json
+stellaops-cli bun inspect --format table
+```
