+# CONTRACT-BUILDID-PROPAGATION-401: Build-ID and Code-ID Propagation
+
+> **Status:** Published
+> **Version:** 1.0.0
+> **Published:** 2025-12-13

+
+## Overview
+
+This contract defines how GNU build-id (ELF), PE GUID, and Mach-O UUID propagate through the reachability pipeline from Scanner to SBOM, Signals, and runtime facts. It ensures consistent identification of binaries across components for deterministic symbol resolution and replay.
+
+---
+
+## 1. Build-ID Sources and Formats
+
+### 1.1 Per-Format Extraction
+
+| Binary Format | Build-ID Source | Prefix | Example |
+|---------------|-----------------|--------|---------|
+| ELF | `.note.gnu.build-id` | `gnu-build-id:` | `gnu-build-id:5f0c7c3cab2eb9bc...` |
+| PE (Windows) | Debug GUID from PE header | `pe-guid:` | `pe-guid:12345678-1234-1234-1234-123456789abc` |
+| Mach-O | `LC_UUID` load command | `macho-uuid:` | `macho-uuid:12345678123412341234123456789abc` |
+
+### 1.2 Canonical Format
+
+```
+build_id = "{prefix}{hex_lowercase}"
+```
+
+- Hex encoding: lowercase, no separators (except PE GUID retains dashes)
+- Minimum length: 16 bytes (32 hex chars) for ELF/Mach-O
+- PE GUID: Standard GUID format with dashes
+
+### 1.3 Fallback When Build-ID Absent
+
+When build-id is not present (stripped binaries, older toolchains):
+
+```json
+{
+  "build_id": null,
+  "build_id_fallback": {
+    "method": "file_hash",
+    "value": "sha256:...",
+    "confidence": 0.7
+  }
+}
+```
+
+**Fallback chain:**
+1. `file_hash` - SHA-256 of entire binary file (confidence: 0.7)
+2. `code_section_hash` - SHA-256 of .text section (confidence: 0.6)
+3. `path_hash` - SHA-256 of file path (confidence: 0.3, last resort)
+
+---
+
+## 2. Code-ID for Name-less Symbols
+
+### 2.1 Purpose
+
+`code_id` provides stable identification for symbols in stripped binaries where the symbol name is unavailable.
+
+### 2.2 Format
+
+```
+code_id = "code:{lang}:{base64url_sha256}"
+```
+
+**Canonical tuple for binary symbols:**
+```
+{format}\0{build_id_or_file_hash}\0{section}\0{addr}\0{size}\0{code_block_hash}
+```
+
+### 2.3 Code Block Hash
+
+For stripped functions, compute hash of the code bytes:
+
+```
+code_block_hash = "sha256:" + hex(SHA256(code_bytes[addr:addr+size]))
+```
+
+---
+
+## 3. Cross-RID (Runtime Identifier) Mapping
+
+### 3.1 Problem Statement
+
+Different platform builds (linux-x64, win-x64, osx-arm64) of the same source code produce different binaries with different build-ids. Runtime facts from one platform must map to the correct binary variant.
+
+### 3.2 Variant Group
+
+Binaries from the same source are grouped by source digest:
+
+```json
+{
+  "variant_group": {
+    "source_digest": "sha256:...",
+    "variants": [
+      {
+        "rid": "linux-x64",
+        "build_id": "gnu-build-id:aaa...",
+        "file_hash": "sha256:..."
+      },
+      {
+        "rid": "win-x64",
+        "build_id": "pe-guid:bbb...",
+        "file_hash": "sha256:..."
+      },
+      {
+        "rid": "osx-arm64",
+        "build_id": "macho-uuid:ccc...",
+        "file_hash": "sha256:..."
+      }
+    ]
+  }
+}
+```
+
+### 3.3 Runtime Fact Correlation
+
+When Signals ingests runtime facts:
+
+1. Extract `build_id` from runtime event
+2. Look up variant group containing this build_id
+3. Correlate with richgraph nodes having matching `build_id`
+4. If no match, fall back to `code_id` + `code_block_hash` matching
+
+---
+
+## 4. SBOM Integration
+
+### 4.1 CycloneDX 1.6 Properties
+
+Build-ID propagates to SBOM via component properties:
+
+```json
+{
+  "type": "library",
+  "name": "libssl.so.3",
+  "version": "3.0.11",
+  "properties": [
+    {"name": "stellaops:build-id", "value": "gnu-build-id:5f0c7c3c..."},
+    {"name": "stellaops:code-id", "value": "code:binary:abc123..."},
+    {"name": "stellaops:file-hash", "value": "sha256:..."}
+  ]
+}
+```
+
+### 4.2 SPDX 3.0 Integration
+
+Build-ID maps to SPDX external references:
+
+```json
+{
+  "spdxId": "SPDXRef-libssl",
+  "externalRef": {
+    "referenceCategory": "PERSISTENT-ID",
+    "referenceType": "gnu-build-id",
+    "referenceLocator": "gnu-build-id:5f0c7c3c..."
+  }
+}
+```
+
+---
+
+## 5. Signals Runtime Facts Schema
+
+### 5.1 Runtime Event with Build-ID
+
+```json
+{
+  "event_type": "function_hit",
+  "timestamp": "2025-12-13T10:00:00Z",
+  "binary": {
+    "path": "/usr/lib/x86_64-linux-gnu/libssl.so.3",
+    "build_id": "gnu-build-id:5f0c7c3c...",
+    "file_hash": "sha256:..."
+  },
+  "symbol": {
+    "name": "SSL_read",
+    "address": "0x12345678",
+    "symbol_id": "sym:binary:..."
+  },
+  "context": {
+    "pid": 12345,
+    "container_id": "abc123..."
+  }
+}
+```
+
+### 5.2 Ingestion Endpoint
+
+```
+POST /signals/runtime-facts
+Content-Type: application/x-ndjson
+Content-Encoding: gzip
+
+{"event_type":"function_hit","binary":{"build_id":"gnu-build-id:..."},...}
+{"event_type":"function_hit","binary":{"build_id":"gnu-build-id:..."},...}
+```
+
+---
+
+## 6. RichGraph Integration
+
+### 6.1 Node with Build-ID
+
+```json
+{
+  "id": "sym:binary:...",
+  "symbol_id": "sym:binary:...",
+  "lang": "binary",
+  "kind": "function",
+  "display": "SSL_read",
+  "build_id": "gnu-build-id:5f0c7c3c...",
+  "code_id": "code:binary:...",
+  "code_block_hash": "sha256:...",
+  "purl": "pkg:deb/debian/libssl3@3.0.11"
+}
+```
+
+### 6.2 CAS Evidence Storage
+
+```
+cas://binary/
+  by-build-id/{build_id}/       # Index by build-id
+    graph.json                   # Associated graph
+    symbols.json                 # Symbol table

+# CONTRACT-INIT-ROOTS-401: Init-Section Synthetic Roots
+
+> **Status:** Published
+> **Version:** 1.0.0
+> **Published:** 2025-12-13

+
+## Overview
+
+This contract defines how ELF/PE/Mach-O initialization sections (`.init_array`, `.ctors`, `DT_INIT`, etc.) are modeled as synthetic roots in reachability graphs. These roots represent code that executes during program load, before `main()`, and must be included in reachability analysis for complete vulnerability assessment.
+
+---
+
+## 1. Init-Section Categories
+
+### 1.1 ELF Init Sections
+
+| Section/Tag | Phase | Order | Description |
+|-------------|-------|-------|-------------|
+| `.preinit_array` / `DT_PREINIT_ARRAY` | `preinit` | 0-N | Executed before dynamic linker init |
+| `.init` / `DT_INIT` | `init` | 0 | Single init function |
+| `.init_array` / `DT_INIT_ARRAY` | `init` | 1-N | Array of init function pointers |
+| `.ctors` | `init` | after init_array | Legacy C++ constructors |
+| `.fini` / `DT_FINI` | `fini` | 0 | Single cleanup function |
+| `.fini_array` / `DT_FINI_ARRAY` | `fini` | 1-N | Array of cleanup function pointers |
+| `.dtors` | `fini` | after fini_array | Legacy C++ destructors |
+
+### 1.2 PE Init Sections
+
+| Mechanism | Phase | Order | Description |
+|-----------|-------|-------|-------------|
+| `DllMain` (DLL_PROCESS_ATTACH) | `init` | 0 | DLL initialization |
+| TLS callbacks | `init` | 1-N | Thread-local storage callbacks |
+| C++ global constructors | `init` | after TLS | Via CRT init table |
+| `DllMain` (DLL_PROCESS_DETACH) | `fini` | 0 | DLL cleanup |
+
+### 1.3 Mach-O Init Sections
+
+| Section | Phase | Order | Description |
+|---------|-------|-------|-------------|
+| `__mod_init_func` | `init` | 0-N | Module init functions |
+| `__mod_term_func` | `fini` | 0-N | Module termination functions |
+
+---
+
+## 2. Synthetic Root Schema
+
+### 2.1 Root Object in richgraph-v1
+
+```json
+{
+  "roots": [
+    {
+      "id": "root:init:0:sym:binary:abc123...",
+      "phase": "init",
+      "source": "init_array",
+      "order": 0,
+      "target_id": "sym:binary:abc123...",
+      "binary_path": "/usr/lib/libfoo.so.1",
+      "build_id": "gnu-build-id:5f0c7c3c..."
+    }
+  ]
+}
+```
+
+### 2.2 Root ID Format
+
+```
+root:{phase}:{order}:{target_symbol_id}
+```
+
+**Examples:**
+- `root:preinit:0:sym:binary:abc...` - First preinit function
+- `root:init:0:sym:binary:def...` - DT_INIT function
+- `root:init:1:sym:binary:ghi...` - First init_array entry
+- `root:main:0:sym:binary:jkl...` - main() function
+- `root:fini:0:sym:binary:mno...` - DT_FINI function
+
+### 2.3 Phase Enumeration
+
+| Phase | Numeric Order | Execution Time |
+|-------|---------------|----------------|
+| `load` | 0 | Dynamic linker resolution |
+| `preinit` | 1 | Before dynamic init |
+| `init` | 2 | During initialization |
+| `main` | 3 | Program entry (main) |
+| `fini` | 4 | During termination |
+
+---
+
+## 3. Root Discovery Algorithm
+
+### 3.1 ELF Root Discovery
+
+```
+1. Parse .dynamic section for DT_PREINIT_ARRAY, DT_INIT, DT_INIT_ARRAY
+2. For each array:
+   a. Read function pointer addresses
+   b. Resolve to symbol (if available) or emit unknown
+   c. Create root with phase + order
+3. Find _start, main, _init, _fini symbols and add as roots
+4. Sort roots by (phase, order, target_id) for determinism
+```
+
+### 3.2 Handling Unresolved Targets
+
+When init array contains address without symbol:
+
+```json
+{
+  "roots": [
+    {
+      "id": "root:init:2:unknown:0x12345678",
+      "phase": "init",
+      "source": "init_array",
+      "order": 2,
+      "target_id": "unknown:0x12345678",
+      "resolved": false,
+      "reason": "No symbol at address 0x12345678"
+    }
+  ],
+  "unknowns": [
+    {
+      "id": "unknown:0x12345678",
+      "type": "unresolved_init_target",
+      "address": "0x12345678",
+      "source": "init_array[2]"
+    }
+  ]
+}
+```
+
+---
+
+## 4. DT_NEEDED Dependency Modeling
+
+### 4.1 Purpose
+
+`DT_NEEDED` entries specify shared library dependencies. These execute their init code before the depending binary's init code.
+
+### 4.2 Schema
+
+```json
+{
+  "dependencies": [
+    {
+      "id": "dep:libssl.so.3",
+      "name": "libssl.so.3",
+      "source": "DT_NEEDED",
+      "order": 0,
+      "resolved_path": "/usr/lib/x86_64-linux-gnu/libssl.so.3",
+      "resolved_build_id": "gnu-build-id:abc..."
+    }
+  ]
+}
+```
+
+### 4.3 Init Order with Dependencies
+
+```
+1. libssl.so.3 preinit → init
+2. libcrypto.so.3 preinit → init
+3. libc.so.6 preinit → init
+4. main_binary preinit → init → main
+```
+
+---
+
+## 5. Patch Oracle Integration
+
+### 5.1 Oracle Expected Roots
+
+```json
+{
+  "expected_roots": [
+    {
+      "id": "root:init:*:sym:binary:*",
+      "phase": "init",
+      "source": "init_array",
+      "required": true,
+      "reason": "Init function must be detected for CVE-2023-XXXX"
+    }
+  ]
+}
+```
+
+### 5.2 Oracle Forbidden Roots
+
+```json
+{
+  "forbidden_roots": [
+    {
+      "id": "root:preinit:*:*",
+      "phase": "preinit",
+      "reason": "Preinit code should not exist after patch"
+    }
+  ]
+}
+```
+
+---
+
+## 6. Policy Integration
+
+### 6.1 Reachability State with Init Roots
+
+When evaluating reachability:
+
+1. If vulnerable function is reachable from `main` → `REACHABLE`
+2. If vulnerable function is reachable from `init` roots → `REACHABLE_INIT`
+3. If vulnerable function is reachable only from `fini` → `REACHABLE_FINI`
+
+### 6.2 Policy DSL Extensions
+
+```yaml
+# Require init-phase reachability for not_affected
+rules:
+  - name: init-reachability-required
+    condition: |
+      vuln.phase_reachable.includes("init") and
+      reachability.confidence >= 0.8
+    action: require_evidence
+
+  - name: init-only-lower-severity
+    condition: |
+      reachability.reachable_phases == ["init"] and
+      not reachability.reachable_phases.includes("main")
+    action: reduce_severity
+    severity_adjustment: -1
+```
+
+---
+
+## 7. Evidence Requirements
+
+### 7.1 Init Root Evidence Bundle
+
+```json
+{
+  "root_evidence": {
+    "root_id": "root:init:0:sym:binary:...",
+    "extraction_method": "dynamic_section",
+    "source_offset": "0x1234",
+    "target_address": "0x5678",
+    "target_symbol": "frame_dummy",
+    "evidence_hash": "sha256:...",
+    "evidence_uri": "cas://binary/roots/sha256:..."
+  }
+}
+```
+
+### 7.2 CAS Storage Layout
+
+```
+cas://reachability/roots/{graph_hash}/
+  init.json          # All init-phase roots
+  fini.json          # All fini-phase roots
+  dependencies.json  # DT_NEEDED graph
+  evidence/
+    root:{id}.json   # Per-root evidence
+```
+
+---
+
+## 8. Determinism Rules
+
+### 8.1 Root Ordering
+
+Roots are sorted by:
+1. Phase (numeric: load=0, preinit=1, init=2, main=3, fini=4)
+2. Order within phase (numeric)
+3. Target ID (string, ordinal)
+
+### 8.2 Root ID Canonicalization
+
+```
+root_id = "root:" + phase + ":" + order + ":" + target_id
+```
+
+All components lowercase, no whitespace.

+# DECISION-NATIVE-TOOLCHAIN-401: Native Lifter and Demangler Selection
+
+> **Status:** Published
+> **Version:** 1.0.0
+> **Published:** 2025-12-13
+> **Owners:** Scanner Guild, Platform Guild
+> **Unblocks:** SCANNER-NATIVE-401-015, SCAN-REACH-401-009
+
+## Decision Summary
+
+This document records the decisions for native binary analysis toolchain selection, enabling implementation of native symbol extraction, callgraph generation, and demangling for ELF/PE/Mach-O binaries.
+
+---
+
+## 1. Component Decisions
+
+### 1.1 ELF Parser
+
+**Decision:** Use custom pure-C# ELF parser
+
+**Rationale:**
+- No native dependencies, portable across platforms
+- Already implemented in `StellaOps.Scanner.Analyzers.Native`
+- Sufficient for symbol table, dynamic section, and relocation parsing
+- Avoids licensing complexity of external libraries
+
+**Implementation:** `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Native/Internal/Elf/`
+
+### 1.2 PE Parser
+
+**Decision:** Use custom pure-C# PE parser
+
+**Rationale:**
+- No native dependencies
+- Already implemented in `StellaOps.Scanner.Analyzers.Native`
+- Handles import/export tables, Debug directory
+- Compatible with air-gapped deployment
+
+**Implementation:** `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Native/Internal/Pe/`
+
+### 1.3 Mach-O Parser
+
+**Decision:** Use custom pure-C# Mach-O parser
+
+**Rationale:**
+- Consistent with ELF/PE approach
+- No native dependencies
+- Sufficient for symbol table and load commands
+
+**Implementation:** `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Native/Internal/MachO/`
+
+### 1.4 Symbol Demangler
+
+**Decision:** Use per-language managed demanglers with native fallback
+
+| Language | Primary Demangler | Fallback |
+|----------|-------------------|----------|
+| C++ (Itanium ABI) | `Demangler.Net` (NuGet) | llvm-cxxfilt via P/Invoke |
+| C++ (MSVC) | `UnDecorateSymbolName` wrapper | None (Windows-specific) |
+| Rust | `rustc-demangle` port | rustfilt via P/Invoke |
+| Swift | `swift-demangle` port | None |
+| D | `dlang-demangler` port | None |
+
+**Rationale:**
+- Managed demanglers provide determinism and portability
+- Native fallback only for edge cases
+- No runtime dependency on external tools
+
+**NuGet packages:**
+```xml
+<PackageReference Include="Demangler.Net" Version="1.0.0" />
+```
+
+### 1.5 Disassembler (Optional, for heuristic analysis)
+
+**Decision:** Use Iced (x86/x64) + Capstone.NET (ARM/others)
+
+| Architecture | Library | NuGet Package |
+|--------------|---------|---------------|
+| x86/x64 | Iced | `Iced` |
+| ARM/ARM64 | Capstone.NET | `Capstone.NET` |
+| Other | Skip disassembly | N/A |
+
+**Rationale:**
+- Iced is pure managed, no native deps for x86
+- Capstone.NET wraps Capstone with native lib
+- Disassembly is optional for heuristic edge detection
+
+### 1.6 Callgraph Extraction
+
+**Decision:** Static analysis only (no dynamic execution)
+
+**Methods:**
+1. Relocation-based: Extract call targets from relocations
+2. Import/Export: Map import references to exports
+3. Symbol-based: Direct and indirect call targets from symbol table
+4. CFG heuristics: Basic block boundary detection (x86 only)
+
+**No dynamic analysis:** Avoids execution risks, portable.

+
+## 2. CI Toolchain Requirements
+
+### 2.1 Build Requirements
+
+| Component | Requirement | Notes |
+|-----------|-------------|-------|
+| .NET SDK | 10.0+ | Required for all builds |
+| Native libs (optional) | Capstone 4.0+ | Only for ARM disassembly |
+| Test binaries | Pre-built fixtures | No compiler dependency in CI |
+
+### 2.2 Test Fixture Strategy
+
+**Decision:** Ship pre-built binary fixtures, not source + compiler
+
+**Rationale:**
+- Deterministic: Same binary hash every run
+- No compiler dependency in CI
+- Smaller CI image footprint
+- Cross-platform: Same fixtures on all runners
+
+**Fixture locations:**
+```
+tests/Binary/fixtures/
+  elf-x86_64/
+    binary.elf           # Pre-built
+    expected.json        # Expected graph
+    expected-hashes.txt  # Determinism check
+  pe-x64/
+    binary.exe
+    expected.json
+  macho-arm64/
+    binary.dylib
+    expected.json
+```
+
+### 2.3 Fixture Generation (Offline)
+
+Fixtures are generated offline by maintainers:
+
+```bash
+# Generate ELF fixture (run once, commit result)
+cd tools/fixtures
+./generate-elf-fixture.sh
+
+# Verify hashes match
+./verify-fixtures.sh
+```
+
+---
+
+## 3. Demangling Contract
+
+### 3.1 Output Format
+
+Demangled names follow this format:
+
+```json
+{
+  "symbol": {
+    "mangled": "_ZN4Curl7Session4readEv",
+    "demangled": "Curl::Session::read()",
+    "source": "itanium-abi",
+    "confidence": 1.0
+  }
+}
+```
+
+### 3.2 Demangling Sources
+
+| Source | Description | Confidence |
+|--------|-------------|------------|
+| `itanium-abi` | Itanium C++ ABI (GCC/Clang) | 1.0 |
+| `msvc` | Microsoft Visual C++ | 1.0 |
+| `rust` | Rust mangling | 1.0 |
+| `swift` | Swift mangling | 1.0 |
+| `fallback` | Native tool fallback | 0.9 |
+| `heuristic` | Pattern-based guess | 0.6 |
+| `none` | No demangling available | 0.3 |
+
+### 3.3 Failed Demangling
+
+When demangling fails:
+
+```json
+{
+  "symbol": {
+    "mangled": "_Z15unknown_format",
+    "demangled": null,
+    "source": "none",
+    "confidence": 0.3,
+    "demangling_error": "Unrecognized mangling scheme"
+  }
+}
+```
+
+---
+
+## 4. Callgraph Edge Types
+
+### 4.1 Edge Type Enumeration
+
+| Type | Description | Confidence |
+|------|-------------|------------|
+| `call` | Direct call instruction | 1.0 |
+| `plt` | PLT/GOT indirect call | 0.95 |
+| `indirect` | Indirect call (vtable, function pointer) | 0.6 |
+| `init_array` | From init_array to function | 1.0 |
+| `tls_callback` | TLS callback invocation | 1.0 |
+| `exception` | Exception handler target | 0.8 |
+| `switch` | Switch table target | 0.7 |
+| `heuristic` | CFG-based heuristic | 0.4 |
+
+### 4.2 Unknown Targets
+
+When call target cannot be resolved:
+
+```json
+{
+  "unknowns": [
+    {
+      "id": "unknown:call:0x12345678",
+      "type": "unresolved_call_target",
+      "source_id": "sym:binary:abc...",
+      "call_site": "0x12345678",
+      "reason": "Indirect call through register"
+    }
+  ]
+}
+```
+
+---
+
+## 5. Performance Constraints
+
+### 5.1 Size Limits
+
+| Metric | Limit | Action on Exceed |
+|--------|-------|------------------|
+| Binary size | 100 MB | Warn, proceed |
+| Symbol count | 1M symbols | Chunk processing |
+| Edge count | 10M edges | Chunk output |
+| Memory usage | 4 GB | Stream processing |
+
+### 5.2 Timeout Constraints
+
+| Operation | Timeout | Action on Exceed |
+|-----------|---------|------------------|
+| ELF parse | 60s | Fail with partial |
+| Demangle all | 120s | Truncate results |
+| CFG analysis | 300s | Skip heuristics |
+| Total analysis | 600s | Fail gracefully |
+
+---
+
+## 6. Integration Points
+
+### 6.1 Scanner Plugin Interface
+
+```csharp
+public interface INativeAnalyzer : IAnalyzerPlugin
+{
+    Task<NativeObservationDocument> AnalyzeAsync(
+        Stream binaryStream,
+        NativeAnalyzerOptions options,
+        CancellationToken ct);
+}
+```
+
+### 6.2 RichGraph Integration
+
+Native analysis results feed into RichGraph:
+
+```
+NativeObservation → NativeReachabilityGraph → RichGraph nodes/edges
+```
+
+### 6.3 Signals Integration
+
+Native symbols with runtime hits:
+
+```
+Signals runtime-facts + RichGraph → ReachabilityFact with confidence
+```
+

-# Sprint 0404 - Scanner .NET Analyzer Detection Gaps
-
-## Topic & Scope
-- Close .NET inventory blind-spots where the analyzer currently emits **no components** unless `*.deps.json` files are present.
-- Add deterministic, offline-first **declared-only** detection paths from build and lock artefacts (csproj/props/CPM/lock files) and make bundling/NativeAOT cases auditable (explicit “under-detected” markers).
-- Preserve current behavior for publish-output scans while expanding coverage for source trees and non-standard deployment layouts.
-- **Working directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet` (tests: `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.DotNet.Tests` and `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Tests`).
-
-## Dependencies & Concurrency
-- Builds on the existing .NET analyzer implementation (`DotNetDependencyCollector` / `DotNetPackageBuilder`) and its fixtures under `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Tests/Fixtures/lang/dotnet`.
-- Must remain parallel-safe under concurrent scans (no shared mutable global state beyond existing concurrency-safe caches).
-- Offline-first: do not restore packages, query feeds, or require MSBuild evaluation that triggers downloads.
-
-## Documentation Prerequisites
-- `docs/README.md`
-- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
-- `docs/modules/platform/architecture-overview.md`
-- `docs/modules/scanner/architecture.md`
-- `src/Scanner/AGENTS.md`

-## Delivery Tracker
-| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
-| --- | --- | --- | --- | --- | --- |
-| 1 | SCAN-DOTNET-404-001 | TODO | Decide declared-vs-installed merge rules (Action 1). | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Add declared-only fallback when no `*.deps.json` exists**: if `DotNetDependencyCollector` finds zero deps files, collect dependencies from (in order): `packages.lock.json`, SDK-style project files (`*.csproj/*.fsproj/*.vbproj`) with `Directory.Build.props` + `Directory.Packages.props` (CPM), and legacy `packages.config`. Emit declared-only components with deterministic metadata including `declaredOnly=true`, `declared.source`, `declared.locator`, `declared.versionSource`, and `declared.isDevelopmentDependency`. Do not attempt full MSBuild evaluation; only use existing lightweight parsers/resolvers. |
-| 2 | SCAN-DOTNET-404-002 | TODO | Requires Action 2 decision on PURL/keying when version unknown. | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Component identity rules for unresolved versions**: when a declared dependency has an unresolved/unknown version (e.g., CPM enabled but missing a version, or property placeholder cannot be resolved), emit a component using `AddFromExplicitKey` (not a versionless PURL) and mark `declared.versionResolved=false` with `declared.unresolvedReason`. Ensure these components cannot collide with real versioned NuGet PURLs. |
-| 3 | SCAN-DOTNET-404-003 | TODO | After task 1/2, implement merge logic and tests. | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Merge declared-only with installed packages when deps.json exists**: when `*.deps.json` packages are present, continue emitting installed `pkg:nuget/<id>@<ver>` components as today. Additionally, emit declared-only components for build/lock dependencies that do not match any installed package (match by normalized id + version). When an installed package exists but has no corresponding declared record, tag the installed component with `declared.missing=true`. Merge must be deterministic and independent of filesystem enumeration order. |
-| 4 | SCAN-DOTNET-404-004 | TODO | Define bounds and target paths (Interlock 2). | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Surface bundling signals as explicit metadata**: integrate `SingleFileAppDetector` and `ILMergedAssemblyDetector` so scans can record “inventory may be incomplete” signals. Minimum requirement: when a likely bundle is detected, emit metadata on the *entrypoint component(s)* (or a synthetic “bundle” component) including `bundle.kind` (`singlefile`, `ilmerge`, `unknown`), `bundle.indicators` (top-N bounded), and `bundle.filePath`. Do not scan the entire filesystem for executables; only scan bounded candidates (e.g., adjacent to deps.json/runtimeconfig, or explicitly configured). |
-| 5 | SCAN-DOTNET-404-005 | TODO | After task 3, decide if edges should include declared edges by default. | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Declared dependency edges output**: when `emitDependencyEdges=true`, include declared edges from build/lock sources in addition to deps.json dependencies, and annotate edge provenance (`edge[*].source=csproj|packages.lock.json|deps.json`). Ensure ordering is stable and bounded (top-N per component if necessary). |
-| 6 | SCAN-DOTNET-404-006 | TODO | Parallel with tasks 1–5; fixtures first. | QA Guild (`src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Tests`, `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.DotNet.Tests`) | **Fixtures + golden outputs**: add fixtures and golden JSON proving new behaviors: (a) **source-tree only** (csproj + Directory.Packages.props + no deps.json), (b) packages.lock.json-only, (c) legacy packages.config-only, (d) mixed case (deps.json present + missing declared record and vice versa), (e) bundled executable indicator fixture (synthetic binary for detector tests, not real apphost). Extend `DotNetLanguageAnalyzerTests` to assert deterministic output and correct declared/installed reconciliation. |
-| 7 | SCAN-DOTNET-404-007 | TODO | After core behavior lands, update docs. | Docs Guild + .NET Analyzer Guild (`docs/modules/scanner`, `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Document .NET analyzer contract**: update `docs/modules/scanner/architecture.md` (or add a .NET analyzer sub-doc under `docs/modules/scanner/`) describing: detection sources and precedence, how declared-only is represented, identity rules for unresolved versions, bundling signals, and known limitations (no full MSBuild evaluation, no restore/feed access). Link this sprint from the doc. |
-| 8 | SCAN-DOTNET-404-008 | TODO | Optional; only if perf regression risk materializes. | Bench Guild (`src/Bench/StellaOps.Bench/Scanner.Analyzers`) | **Benchmark declared-only scanning**: add a deterministic bench that scans a representative source-tree fixture (many csproj/props/lockfiles) and records elapsed time + component counts. Establish a baseline ceiling and ensure CI can run it offline. |

-## Wave Coordination
-| Wave | Guild owners | Shared prerequisites | Status | Notes |
-| --- | --- | --- | --- | --- |
-| A: Declared-only sources | .NET Analyzer Guild + QA Guild | Decisions in Action 1–2 | TODO | Enable detection without deps.json. |
-| B: Reconciliation & edges | .NET Analyzer Guild + QA Guild | Wave A | TODO | Declared vs installed merge + edge provenance. |
-| C: Bundling signals | .NET Analyzer Guild + QA Guild | Interlock 2 | TODO | Make bundling/under-detection auditable. |
-| D: Docs & bench | Docs Guild + Bench Guild | Waves A–C | TODO | Contract + perf guardrails. |
-
-## Wave Detail Snapshots
-- **Wave A:** Standalone declared-only inventory (lockfiles/projects/CPM/packages.config) with deterministic identity and evidence.
-- **Wave B:** Merge declared-only with deps.json-installed packages; emit declared-missing/lock-missing markers and optional edge provenance.
-- **Wave C:** Bounded bundling detection integrated; no filesystem-wide binary scanning.
-- **Wave D:** Contract documentation + optional benchmark to prevent regressions.
-
-## Interlocks
-- **Identity & collisions:** Explicit-key components for unresolved versions must never collide with real `pkg:nuget/<id>@<ver>` PURLs (Action 2).
-- **Bundling scan bounds:** bundling detectors must be applied only to bounded candidate files; scanning “all executables” is forbidden for perf/safety.
-- **No restore/MSBuild evaluation:** do not execute MSBuild or `dotnet restore`; use only lightweight parsing and local file inspection.
-
-## Upcoming Checkpoints
-- 2025-12-13: Approve declared-vs-installed precedence and unresolved identity rules (Actions 1–2).
-- 2025-12-16: Wave A complete with fixtures proving deps.json-free detection.
-- 2025-12-18: Wave B complete (merge + edge provenance) with mixed-case fixtures.
-- 2025-12-20: Wave C complete (bundling signals) with bounded candidate selection and tests.
-- 2025-12-22: Docs updated; optional bench decision made; sprint ready for DONE review.

-## Action Tracker
-| # | Action | Owner | Due (UTC) | Status | Notes |
-| --- | --- | --- | --- | --- | --- |
-| 1 | Define deterministic precedence for dependency sources (deps.json vs lock vs project vs packages.config) and merge rules for “declared missing / installed missing”. | Project Mgmt + .NET Analyzer Guild | 2025-12-13 | Open | Must be testable via fixtures; no traversal-order dependence. |
-| 2 | Decide component identity strategy when version cannot be resolved (explicit key scheme + required metadata fields). | Project Mgmt + Scanner Guild | 2025-12-13 | Open | Must avoid false matches and collisions with PURLs. |
-| 3 | Define which files qualify as “bundling detector candidates” (adjacent to deps.json/runtimeconfig, configured paths, size limits). | .NET Analyzer Guild + Security Guild | 2025-12-13 | Open | Prevent scanning untrusted large binaries broadly. |
-
-## Decisions & Risks
-- **Decision (pending):** precedence + identity strategy (see Action Tracker 1–2).
-
-| Risk ID | Risk | Impact | Likelihood | Mitigation | Owner | Trigger / Signal |
-| --- | --- | --- | --- | --- | --- | --- |
-| R1 | Declared-only scanning causes false positives (declared deps not actually shipped). | Medium | Medium | Mark `declaredOnly=true`; keep installed vs declared distinction; allow policy/UI to down-rank declared-only. | .NET Analyzer Guild | Increased component counts without corresponding runtime evidence. |
-| R2 | Unresolved version handling creates unstable component identity. | High | Medium | Use explicit-key with stable recipe; include source+locator in key material if needed. | Project Mgmt | Flaky golden outputs; duplicate collisions across projects. |
-| R3 | Bundling detectors cause perf regressions or scan untrusted huge binaries. | High | Low/Medium | Bounded candidate selection + size caps; emit “skipped” markers when exceeding limits. | Security Guild + .NET Analyzer Guild | CI timeouts; scanning large container roots. |
-| R4 | Adding declared edges creates noisy graphs. | Medium | Medium | Gate behind `emitDependencyEdges`; keep edges bounded and clearly sourced. | .NET Analyzer Guild | Export/UI performance degradation. |
-
-## Execution Log
-| Date (UTC) | Update | Owner |
-| --- | --- | --- |
-| 2025-12-12 | Sprint created to expand .NET analyzer coverage beyond deps.json (declared-only detection, reconciliation, bundling signals, fixtures/docs/bench). | Project Mgmt |

-| 1 | SCAN-PY-405-001 | DONE | Implement VFS/discovery pipeline; then codify identity/precedence in tests. | Python Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python`) | **Wire layout-aware discovery into `PythonLanguageAnalyzer`**: stop treating "any `*.dist-info` anywhere" as an installed package source. Use `PythonInputNormalizer` + `PythonVirtualFileSystem` + `PythonPackageDiscovery` as the first-pass inventory (site-packages, editable paths, wheels, zipapps, container layer roots). Ensure deterministic path precedence (later/higher-confidence wins) and bounded scanning (no unbounded full-tree recursion for patterns). Emit package-kind + confidence metadata (`pkg.kind`, `pkg.confidence`, `pkg.location`) for every component. |
-| 2 | SCAN-PY-405-002 | BLOCKED | Blocked on Action 1 identity scheme for non-versioned explicit keys. | Python Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python`) | **Preserve dist-info "deep evidence" while expanding coverage**: for any discovered package with a real `*.dist-info`/`*.egg-info`, continue to enrich with `PythonDistributionLoader` evidence (METADATA/RECORD/WHEEL/entrypoints, RECORD verification stats). For packages discovered without dist-info (e.g., Poetry editable, vendored, zipapp), emit components using `AddFromExplicitKey` with stable identity rules (Action 1) and evidence pointing to the originating file(s) (`pyproject.toml`, lockfile, archive path). |
-| 3 | SCAN-PY-405-003 | BLOCKED | Await Action 2 (lock/requirements precedence + supported formats scope). | Python Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python`) | **Expand lockfile/requirements detection and parsing**: upgrade `PythonLockFileCollector` to (a) discover lock/requirements files deterministically (root + nested common paths), (b) support `-r/--requirement` includes with cycle detection, (c) correctly handle editable `-e/--editable` lines, (d) parse PEP 508 specifiers (not only `==/===`) and `name @ url` direct references, and (e) include Pipenv `develop` section. Add opt-in support for at least one modern lock (`uv.lock` or `pdm.lock`) with deterministic record ordering and explicit "unsupported line" counters. |
-| 4 | SCAN-PY-405-004 | BLOCKED | Await Action 3 (container overlay handling contract). | Python Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python`) | **Correct container-layer inventory semantics**: when scanning raw OCI layer trees (`layers/`, `.layers/`, `layer*/`), honor whiteouts/overlay ordering so removed packages are not reported. Use/extend `Internal/Packaging/Adapters/ContainerLayerAdapter` semantics as the source of truth for precedence. Emit explicit metadata markers when inventory is partial due to missing overlay context (e.g., `container.overlayIncomplete=true`). |
-| 5 | SCAN-PY-405-005 | BLOCKED | Await Action 4 (vendored deps representation contract). | Python Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python`) | **Surface vendored (bundled) Python deps**: integrate `VendoredPackageDetector` so known vendoring patterns (`*_vendor`, `third_party`, `requests.packages`, etc.) are detected. Emit either (a) separate "embedded" components with bounded evidence locators (preferred) or (b) a bounded metadata summary on the parent package (`vendored.detected=true`, `vendored.packages`, `vendored.paths`). Never emit unbounded file/module lists; cap to top-N deterministic samples. |

Extend this by optionally mapping source-tree imports (`PythonImportAnalysis`) and/or runtime evidence (`PythonRuntimeEvidenceCollector`) to packages (via `TopLevelModules`) so "likely used" can be signaled deterministically (bounded, opt-in). Add `scope` metadata using `PythonScopeClassifier` (prod/dev/docs/build) based on lock sections and requirements file names. |
-| 7 | SCAN-PY-405-007 | BLOCKED | Blocked on Actions 2-4 for remaining fixtures (requirements/includes/editables, whiteouts, vendoring). | QA Guild (`src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Python.Tests`) | **Fixtures + golden outputs**: add fixtures proving new detection paths: (a) conda env (`conda-meta/*.json`) without dist-info, (b) requirements with `-r` includes + `-e .` editable, (c) Pipfile.lock with `default` + `develop`, (d) wheel file in workspace (no extraction), (e) zipapp/pyz with embedded requirements, (f) container layers with whiteouts hiding a dist-info dir, (g) vendored dependency directory under a package. Extend `PythonLanguageAnalyzerTests.cs` to assert deterministic ordering, stable identities, and bounded metadata. |
-| 8 | SCAN-PY-405-008 | DONE | After core behavior lands, update docs + perf guard. | Docs Guild + Bench Guild (`docs/modules/scanner`, `src/Bench/StellaOps.Bench/Scanner.Analyzers`) | **Document + benchmark Python analyzer contract**: update `docs/modules/scanner/architecture.md` (or add a Python analyzer sub-doc) describing detection sources & precedence, lock parsing rules, container overlay semantics, vendoring representation, and identity rules for non-versioned components. Add a deterministic offline bench scanning a representative fixture (many packages + lockfiles) and record baseline ceilings (time + components count). |

-## Wave Coordination
-| Wave | Guild owners | Shared prerequisites | Status | Notes |
-| --- | --- | --- | --- | --- |
-| A: Discovery Backbone | Python Analyzer Guild + QA Guild | Actions 1–2 | TODO | Wire input normalization + package discovery; reduce false positives. |
-| B: Lock Coverage | Python Analyzer Guild + QA Guild | Action 2 | TODO | Requirements/includes/editables + modern locks + Pipenv develop. |
-| C: Containers & Vendoring | Python Analyzer Guild + QA Guild | Actions 3–4 | TODO | Whiteouts/overlay correctness + vendored packages surfaced. |
-| D: Usage & Scope | Python Analyzer Guild + QA Guild | Interlock 4 | TODO | Improve “used by entrypoint” + scope classification (opt-in). |
-| E: Docs & Bench | Docs Guild + Bench Guild | Waves A–D | TODO | Contract doc + offline benchmark. |
-
-## Wave Detail Snapshots
-- **Wave A:** Layout-aware discovery (VFS + discovery) becomes the primary inventory path; deterministic precedence and bounded scans.
-- **Wave B:** Lock parsing supports real-world formats (includes, editables, PEP 508) and emits declared-only components without silent drops.
-- **Wave C:** Container overlay semantics prevent false positives; vendored deps become auditable inventory signals.
-- **Wave D:** Optional, deterministic “used likely” signals and package scopes reduce noise and improve reachability inputs.
-- **Wave E:** Documented contract + perf ceiling ensures the new logic stays stable.
-
-## Interlocks
-- **Identity & collisions:** Components without reliable versions (vendored/local/zipapp/project) must use `AddFromExplicitKey` with a stable, non-colliding key scheme. (Action 1)
-- **Lock precedence:** When multiple sources exist (requirements + Pipfile.lock + poetry.lock + pyproject), precedence must be explicit and deterministic (Action 2).
-- **Container overlay correctness:** If scanning raw layers, whiteouts must be honored; otherwise mark overlay as incomplete and avoid false inventory claims. (Action 3)
-- **“Used-by-entrypoint” semantics:** Any import/runtime-based usage hints must be bounded, opt-in, and deterministic; avoid turning heuristic signals into hard truth. (Interlock 4)
-
-## Upcoming Checkpoints
-- 2025-12-13: Approve identity scheme + lock precedence + container overlay expectations (Actions 1–3).
-- 2025-12-16: Wave A complete with fixtures proving VFS-based discovery is stable and deterministic.
-- 2025-12-18: Wave B complete with real-world requirements/includes/editables + Pipenv develop coverage.
-- 2025-12-20: Wave C complete (whiteouts/overlay + vendoring) with bounded outputs.
-- 2025-12-22: Wave D decision + implementation (if enabled) and Wave E docs/bench complete; sprint ready for DONE review.

-## Action Tracker
-| # | Action | Owner | Due (UTC) | Status | Notes |
-| --- | --- | --- | --- | --- | --- |
-| 1 | Decide explicit-key identity scheme for non-versioned Python components (vendored/local/zipapp/project) and document it. | Project Mgmt + Scanner Guild | 2025-12-13 | Open | Must avoid collisions with `pkg:pypi/<name>@<ver>` PURLs; prefer explicit-key when uncertain. |
-| 2 | Decide lock/requirements precedence order + dedupe rules and document them as a contract. | Project Mgmt + Python Analyzer Guild | 2025-12-13 | Open | Must not depend on filesystem traversal order; include “unsupported line count” requirement. |
-| 3 | Decide container overlay handling contract for raw `layers/` inputs (whiteouts, ordering, “merged vs raw” expectations). | Project Mgmt + Scanner Guild | 2025-12-13 | Open | If upstream provides merged rootfs, clarify whether Python analyzer should still scan raw layers. |
-| 4 | Decide how vendored deps are represented (separate embedded components vs parent-only metadata) and how to avoid false vuln matches. | Project Mgmt + Python Analyzer Guild | 2025-12-13 | Open | Prefer separate components only when identity/version is defensible; otherwise bounded metadata summary. |
-
-## Decisions & Risks
-- **Decision (pending):** Identity scheme for non-versioned components, lock precedence, and container overlay expectations (Action Tracker 1-3).
-- **BLOCKED:** `SCAN-PY-405-002` needs an approved explicit-key identity scheme (Action Tracker 1) before emitting non-versioned components (vendored/local/zipapp/project).
-- **BLOCKED:** `SCAN-PY-405-003` awaits lock/requirements precedence + supported formats scope (Action Tracker 2).
-- **BLOCKED:** `SCAN-PY-405-004` awaits container overlay handling contract for raw `layers/` inputs (Action Tracker 3).
-- **BLOCKED:** `SCAN-PY-405-005` awaits vendored deps representation contract (Action Tracker 4).
-- **BLOCKED:** `SCAN-PY-405-006` awaits Interlock 4 decision on "used-by-entrypoint" semantics (avoid turning heuristics into truth).
-- **BLOCKED:** `SCAN-PY-405-007` awaits Actions 2-4 to fixture remaining semantics (includes/editables, overlay/whiteouts, vendoring).
-
-| Risk ID | Risk | Impact | Likelihood | Mitigation | Owner | Trigger / Signal |
-| --- | --- | --- | --- | --- | --- | --- |
-| R1 | Broader lock parsing introduces non-determinism (order/duplication) across platforms. | High | Medium | Stable sorting, explicit precedence, and golden fixtures for each format (incl. `-r` cycles). | Python Analyzer Guild | Flaky golden outputs; different results between Windows/Linux agents. |
-| R2 | Container-layer scanning reports packages that are effectively deleted by whiteouts. | High | Medium | Implement/validate overlay semantics; add whiteout fixtures; mark overlayIncomplete when uncertain. | Scanner Guild | Inventory shows duplicates; reports packages not present in merged rootfs. |
-| R3 | Vendored detection inflates inventory and causes false vulnerability correlation. | High | Medium | Prefer explicit-key or bounded metadata when version unknown; require defensive identity rules + docs. | Python Analyzer Guild | Sudden vuln-match spike on vendored-only signals. |
-| R4 | Integrating VFS/discovery increases CPU/memory or scan time. | Medium | Medium | Bounds on scanning; benchmark; avoid full-tree recursion for patterns; reuse existing parsed results. | Bench Guild | Bench regression beyond agreed ceiling; timeouts in CI. |
-| R5 | “Used-by-entrypoint” heuristics get misinterpreted as truth. | Medium | Low/Medium | Keep heuristic usage signals opt-in, clearly labeled, and bounded; document semantics. | Project Mgmt | Downstream policy relies on “used” incorrectly; unexpected risk decisions. |

-# Sprint 0408 - Scanner Language Detection Gaps (Implementation Program)
-
-## Topic & Scope
-- Implement **all currently identified detection gaps** across the language analyzers: Java, .NET, Python, Node, Bun.
-- Align cross-analyzer contracts where gaps overlap: **identity safety** (PURL vs explicit-key), **evidence locator precision**, **container layer/rootfs discovery**, and **no host-path leakage**.
-- Produce hard evidence for each analyzer: deterministic fixtures + golden outputs, plus docs (and optional benches where perf risk exists).
-- **Working directory:** `src/Scanner` (implementation occurs under `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.*` and `src/Scanner/__Tests/*`; this sprint is the coordination source-of-truth spanning multiple analyzer folders).
-
-## Dependencies & Concurrency
-- Language sprints (source-of-truth for per-analyzer detail):
-  - Java: `docs/implplan/SPRINT_0403_0001_0001_scanner_java_detection_gaps.md`
-  - .NET: `docs/implplan/SPRINT_0404_0001_0001_scanner_dotnet_detection_gaps.md`
-  - Python: `docs/implplan/SPRINT_0405_0001_0001_scanner_python_detection_gaps.md`
-  - Node: `docs/implplan/SPRINT_0406_0001_0001_scanner_node_detection_gaps.md`
-  - Bun: `docs/implplan/SPRINT_0407_0001_0001_scanner_bun_detection_gaps.md`
-- Concurrency model:
-  - Language implementations may proceed in parallel once cross-analyzer “contract” decisions are frozen (Actions 1–3).
-  - Avoid shared mutable state changes across analyzers; keep deterministic ordering; do not introduce network fetches.
-

-## Delivery Tracker
-| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
-| --- | --- | --- | --- | --- | --- |
-| 1 | SCAN-PROG-408-001 | DOING | Requires Action 1. | Scanner Guild + Security Guild + Export/UI/CLI Consumers | **Freeze cross-analyzer identity safety contract**: define a single, documented rule-set for when an analyzer emits (a) a concrete PURL and (b) an explicit-key component. Must cover: version ranges/tags, local paths, workspace/link/file deps, git deps, and "unknown" versions. Output: a canonical doc under `docs/modules/scanner/` (path chosen in Action 1) + per-analyzer unit tests asserting "no invalid PURLs" for declared-only / non-concrete inputs. |
-| 2 | SCAN-PROG-408-002 | DOING | Requires Action 2. | Scanner Guild + Export/UI/CLI Consumers | **Freeze cross-analyzer evidence locator contract**: define deterministic locator formats for (a) lockfile entries, (b) nested artifacts (e.g., Java "outer!inner!path"), and (c) derived evidence records. Output: canonical doc + at least one golden fixture per analyzer asserting exact locator strings and bounded evidence sizes. |
-| 3 | SCAN-PROG-408-003 | DOING | Requires Action 3. | Scanner Guild | **Freeze container layout discovery contract**: define which analyzers must discover projects under `layers/`, `.layers/`, and `layer*/` layouts, how ordering/whiteouts are handled (where applicable), and bounds (depth/roots/files). Output: canonical doc + fixtures proving parity for Node/Bun/Python (and any Java/.NET container behaviors where relevant). |
-| 4 | SCAN-PROG-408-004 | DONE | Unblocks Bun sprint DOING. | Project Mgmt + Scanner Guild | **Create missing Bun analyzer charter**: add `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Bun/AGENTS.md` synthesizing constraints from `docs/modules/scanner/architecture.md` and this sprint + `SPRINT_0407_0001_0001_scanner_bun_detection_gaps.md`. Must include: allowed directories, test strategy, determinism rules, identity/evidence conventions, and "no absolute paths" requirement. |
-| 5 | SCAN-PROG-408-JAVA | TODO | Actions 1–2 recommended before emission format changes. | Java Analyzer Guild + QA Guild | **Implement all Java gaps** per `docs/implplan/SPRINT_0403_0001_0001_scanner_java_detection_gaps.md`: (a) embedded libs inside fat archives without extraction, (b) `pom.xml` fallback when properties missing, (c) multi-module Gradle lock discovery + deterministic precedence, (d) runtime image component emission from `release`, (e) replace JNI string scanning with bytecode-based JNI analysis. Acceptance: Java analyzer tests + new fixtures/goldens; bounded scanning with explicit skipped markers. |
-| 6 | SCAN-PROG-408-DOTNET | TODO | Actions 1–2 recommended before adding declared-only identities. | .NET Analyzer Guild + QA Guild | **Implement all .NET gaps** per `docs/implplan/SPRINT_0404_0001_0001_scanner_dotnet_detection_gaps.md`: (a) declared-only fallback when no deps.json, (b) non-colliding identity for unresolved versions, (c) deterministic merge of declared vs installed packages, (d) bounded bundling signals, (e) optional declared edges provenance, (f) fixtures/docs (and optional bench). Acceptance: `.NET` analyzer emits components for source trees with lock/build files; no restore/MSBuild execution; deterministic outputs. |
-| 7 | SCAN-PROG-408-PYTHON | TODO | Actions 1–3 recommended before overlay/identity changes. | Python Analyzer Guild + QA Guild | **Implement all Python gaps** per `docs/implplan/SPRINT_0405_0001_0001_scanner_python_detection_gaps.md`: (a) layout-aware discovery (avoid “any dist-info anywhere”), (b) expanded lock/requirements parsing (includes/editables/PEP508/direct refs), (c) correct container overlay/whiteout semantics (or explicit overlayIncomplete markers), (d) vendored dependency surfacing with safe identity rules, (e) optional used-by signals (bounded/opt-in), (f) fixtures/docs/bench. Acceptance: deterministic fixtures for lock formats and container overlays; no invalid “editable-as-version” PURLs per Action 1. |
-| 8 | SCAN-PROG-408-NODE | TODO | Actions 1–3 recommended before declared-only emission + locators. | Node Analyzer Guild + QA Guild | **Implement all Node gaps** per `docs/implplan/SPRINT_0406_0001_0001_scanner_node_detection_gaps.md`: (a) emit declared-only components safely (no range-as-version PURLs), (b) multi-version lock fidelity `(name@version)` mapping, (c) Yarn Berry lock support, (d) pnpm schema hardening, (e) correct nested node_modules name extraction, (f) workspace glob bounds + container app-root detection parity, (g) bounded import evidence + consistent package.json hashing, (h) docs/bench. Acceptance: fixtures cover multi-version locks and Yarn v3; determinism tests prove stable ordering and locator strings. |
-| 9 | SCAN-PROG-408-BUN | TODO | Actions 1–3 recommended before identity/scope changes. | Bun Analyzer Guild + QA Guild | **Implement all Bun gaps** per `docs/implplan/SPRINT_0407_0001_0001_scanner_bun_detection_gaps.md`: (a) discover projects under container layer layouts and do not skip `.layers`, (b) declared-only fallback for bunfig-only/no-lock/no-install, (c) bun.lock v1 graph-based dev/optional/peer classification and meaningful includeDev filtering, (d) version-specific patch mapping with relative paths only, (e) stronger evidence locators + bounded hashing, (f) identity safety for non-npm sources. Acceptance: new fixtures (`container-layers`, `bunfig-only`, `patched-multi-version`, dev-classification) + updated goldens; no absolute path leakage. |
-| 10 | SCAN-PROG-408-INTEG-001 | TODO | After tasks 5–9 land. | QA Guild + Scanner Guild | **Integration determinism gate**: run the full language analyzer test matrix (Java/.NET/Python/Node/Bun) and add/adjust determinism tests so ordering, evidence locators, and identity rules remain stable. Any “skipped” work due to bounds must be explicit and deterministic (no silent drops). |
-| 11 | SCAN-PROG-408-DOCS-001 | TODO | After Actions 1–3 are frozen. | Docs Guild + Scanner Guild | **Update scanner docs with final contracts**: link the per-language analyzer contract docs and this sprint from `docs/modules/scanner/architecture.md` (or the closest canonical scanner doc). Must include: identity rules, evidence locator rules, container layout handling, and bounded scanning policy. |

-## Wave Coordination
-| Wave | Guild owners | Shared prerequisites | Status | Notes |
-| --- | --- | --- | --- | --- |
-| A: Contracts | Scanner Guild + Security Guild + Consumers | Actions 1–3 | TODO | Freeze identity/evidence/container contracts first to avoid rework. |
-| B: Language Implementation | Analyzer Guilds + QA Guild | Wave A recommended | TODO | Java/.NET/Python/Node/Bun run in parallel once contracts are stable. |
-| C: Integration & Docs | QA Guild + Docs Guild | Wave B | TODO | Determinism gates + contract documentation. |
-
-## Wave Detail Snapshots
-- **Wave A:** Single cross-analyzer contract for identity, evidence locators, and container layout discovery (with tests).
-- **Wave B:** Implement each analyzer sprint’s tasks with fixtures + deterministic goldens.
-- **Wave C:** End-to-end test pass + documented analyzer promises and limitations.
-
-## Interlocks
-- **No invalid PURLs:** declared-only/range/git/file/link/workspace deps must not become “fake versions”; explicit-key is required when version is not concrete. (Action 1)
-- **Locator stability:** evidence locators are external-facing (export/UI/CLI); changes must be deliberate, documented, and golden-tested. (Action 2)
-- **Container bounds:** layer-root discovery and overlay semantics must remain bounded and auditable (skipped markers) to stay safe on untrusted inputs. (Action 3)
-- **No absolute paths:** metadata/evidence must be project-relative; no host path leakage (patch discovery and symlink realpaths are common pitfalls).
-
-## Upcoming Checkpoints
-- 2025-12-13: Freeze Actions 1–3 (contracts) and Action 4 (Bun AGENTS).
-- 2025-12-16: Java + .NET waves reach “fixtures passing” milestone.
-- 2025-12-18: Python + Node waves reach “fixtures passing” milestone.
-- 2025-12-20: Bun wave reaches “fixtures passing” milestone; all language sprints ready for integration run.
-- 2025-12-22: Integration determinism gate + docs complete; sprint ready for DONE review.

+# Sprint 3412 - PostgreSQL Durability Phase 2
+
+## Topic & Scope
+- Implement PostgreSQL storage for modules currently using in-memory/filesystem storage after MongoDB removal
+- Complete Excititor PostgreSQL migration (Provider, Observation, Attestation, Timeline stores still in-memory)
+- Restore production durability for AirGap, TaskRunner, Signals, Graph, PacksRegistry, SbomService
+- Complete Notify Postgres repository implementation for missing repos
+- Fix Graph.Indexer determinism test failures
+- **Working directory:** cross-module; all modules with in-memory/filesystem storage
+
+## Dependencies & Concurrency
+- Upstream: Sprint 3410 (MongoDB Final Removal) - COMPLETE
+- Upstream: Sprint 3411 (Notifier Architectural Cleanup) - COMPLETE
+- Each module can be implemented independently; modules can be worked in parallel
+- Prefer Excititor, AirGap.Controller and TaskRunner first due to HIGH production risk
+
+## Documentation Prerequisites
+- docs/db/SPECIFICATION.md
+- docs/operations/postgresql-guide.md
+- Module AGENTS.md files
+- Existing Postgres storage implementations (Authority, Scheduler, Concelier) as reference patterns
+
+## Database Abstraction Layer Requirements
+
+**All implementations MUST follow the established pattern:**
+
+```
+DataSourceBase (Infrastructure.Postgres)
+    └── ModuleDataSource : DataSourceBase
+            └── RepositoryBase<TDataSource>
+                    └── ConcreteRepository : RepositoryBase<ModuleDataSource>, IRepository
+```
+
+### Reference Implementations
+
+| Pattern | Reference Location |
+|---------|-------------------|
+| DataSourceBase | `src/__Libraries/StellaOps.Infrastructure.Postgres/Connections/DataSourceBase.cs` |
+| RepositoryBase | `src/__Libraries/StellaOps.Infrastructure.Postgres/Repositories/RepositoryBase.cs` |
+| Module DataSource | `src/Authority/__Libraries/StellaOps.Authority.Storage.Postgres/AuthorityDataSource.cs` |
+| Repository Example | `src/Authority/__Libraries/StellaOps.Authority.Storage.Postgres/Repositories/ApiKeyRepository.cs` |
+| Test Fixture | `src/__Libraries/StellaOps.Infrastructure.Postgres.Testing/PostgresIntegrationFixture.cs` |
+
+### Implementation Checklist
+
+Each new Postgres repository MUST:
+- [ ] Inherit from `RepositoryBase<TModuleDataSource>`
+- [ ] Implement module-specific interface (e.g., `IVexProviderStore`)
+- [ ] Accept `tenantId` as first parameter in all queries
+- [ ] Use base class helpers: `QueryAsync`, `QuerySingleOrDefaultAsync`, `ExecuteAsync`
+- [ ] Use `AddParameter`, `AddJsonbParameter` for safe parameter binding
+- [ ] Include static mapper function for data mapping
+- [ ] Be registered as **Scoped** in DI (DataSource is Singleton)
+- [ ] Include embedded SQL migrations
+- [ ] Have integration tests using `PostgresIntegrationFixture`
+

+## Wave Coordination
+- **Wave 1 (HIGH PRIORITY):** T12.0 (Excititor), T12.1 (AirGap), T12.2 (TaskRunner) - production durability critical
+- **Wave 2:** T12.3 (Notify repos) - completes Notify Postgres migration
+- **Wave 3:** T12.4-T12.7 (Signals, Graph, PacksRegistry, SbomService) - can be parallelized
+
+## Current Storage Locations
+
+| Module | Current Implementation | Files |
+|--------|------------------------|-------|
+| Excititor | Postgres COMPLETE | All stores implemented: `PostgresVexProviderStore`, `PostgresVexObservationStore`, `PostgresVexAttestationStore`, `PostgresVexTimelineEventStore` |
+| AirGap.Controller | Postgres COMPLETE | `PostgresAirGapStateStore` in `StellaOps.AirGap.Storage.Postgres` |
+| TaskRunner | Postgres COMPLETE | `PostgresPackRunStateStore`, `PostgresPackRunApprovalStore`, `PostgresPackRunLogStore`, `PostgresPackRunEvidenceStore` in `StellaOps.TaskRunner.Storage.Postgres` |
+| Signals | Filesystem + In-memory | `src/Signals/StellaOps.Signals/Storage/FileSystemCallgraphArtifactStore.cs` |
+| Graph.Indexer | In-memory | `src/Graph/StellaOps.Graph.Indexer/` - InMemoryIdempotencyStore, in-memory graph writer |

+| Notify | Partial Postgres | Missing: PackApproval, ThrottleConfig, OperatorOverride, Localization repos |
+
+## Decisions & Risks
+- **Decisions:** All Postgres implementations MUST follow the `RepositoryBase<TDataSource>` abstraction pattern established in Authority, Scheduler, and Concelier modules. Use Testcontainers for integration testing. No direct Npgsql access without abstraction.
+- **Risks:**
+  - ~~Excititor VEX attestations not persisted until T12.0 completes - HIGH PRIORITY~~ **MITIGATED** - T12.0 complete
+  - ~~AirGap sealing state loss on restart until T12.1 completes~~ **MITIGATED** - T12.1 complete
+  - ~~TaskRunner has no HA/scaling support until T12.2 completes~~ **MITIGATED** - T12.2 complete
+  - Graph.Indexer determinism tests currently failing (null edge resolution, duplicate nodes)
+
+| Risk | Mitigation |
+| --- | --- |
+| Production durability gaps | Prioritize Excititor, AirGap and TaskRunner (Wave 1) |
+| Schema design complexity | Reference existing Postgres implementations (Authority, Scheduler) |
+| Inconsistent abstraction patterns | Enforce `RepositoryBase<TDataSource>` pattern via code review |
+| Test infrastructure | Use existing Testcontainers patterns from Scanner.Storage |
+| Excititor in-memory stores have complex semantics | Use InMemoryVexStores.cs as behavioral specification |
+

+# Sprint 0402 - Scanner Go Analyzer Gaps
+
+## Topic & Scope
+- Close correctness and determinism gaps in the Go language analyzer across **source + binary** scenarios (go.mod/go.sum/go.work/vendor + embedded buildinfo).
+- Ensure **binary evidence actually takes precedence** over source evidence (including when both are present in the scan root) without duplicate/contradictory components.
+- Harden parsing and metadata semantics for Go workspaces and module directives (workspace-wide `replace`, duplicate `replace`, `retract` semantics).
+- Reduce worst-case IO/memory by bounding buildinfo/DWARF reads while keeping offline-first behavior and deterministic outputs.
+- **Working directory:** `src/Scanner` (primary code: `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Go`; tests: `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Go.Tests`; docs: `docs/modules/scanner/`).
+
+## Dependencies & Concurrency
+- Depends on shared language component identity/merge behavior: `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang/Core/LanguageComponentRecord.cs`.
+- Concurrency-safe with other language gap sprints (`SPRINT_0403_0001_0001_scanner_java_detection_gaps.md`, `SPRINT_0404_0001_0001_scanner_dotnet_detection_gaps.md`, `SPRINT_0405_0001_0001_scanner_python_detection_gaps.md`, `SPRINT_0406_0001_0001_scanner_node_detection_gaps.md`, `SPRINT_0407_0001_0001_scanner_bun_detection_gaps.md`) unless we change cross-analyzer merge/identity conventions (see Decisions & Risks).

+## Delivery Tracker
+| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
+| --- | --- | --- | --- | --- | --- |
+| 1 | SCAN-GO-402-001 | DONE | Reversed scan order; binary first. | Go Analyzer Guild | **Fix precedence when both source + binary exist**: Reversed scan order so binaries are processed first (Phase 1), then source (Phase 2). Binary components now include `provenance=binary` metadata. Main module paths are tracked separately to suppress source `(devel)` versions when binary evidence exists. |
+| 2 | SCAN-GO-402-002 | DONE | Workspace replaces propagated. | Go Analyzer Guild | **Apply `go.work` workspace-wide replacements**: Added `WorkspaceReplaces` property to `GoProject` record. Workspace-level `replace` directives are now parsed from `go.work` and propagated to all member module inventories. Module-level replaces take precedence over workspace-level for same key. |
+| 3 | SCAN-GO-402-003 | DONE | Duplicate keys handled. | Go Analyzer Guild | **Harden `replace` parsing + duplicate keys**: Replaced `ToImmutableDictionary` (which throws on duplicates) with manual dictionary building that handles duplicates with last-one-wins semantics within each scope (workspace vs module). |
+| 4 | SCAN-GO-402-004 | DONE | False positives removed. | Go Analyzer Guild + Security Guild | **Correct `retract` semantics**: Removed false-positive `retractedVersions.Contains(module.Version)` check from conflict detector. Added documentation clarifying that `retract` only applies to the declaring module and cannot be determined for dependencies offline. |
+| 5 | SCAN-GO-402-005 | DONE | Windowed reads implemented. | Go Analyzer Guild + Bench Guild | **Bound buildinfo/DWARF IO**: Implemented bounded windowed reads for both buildinfo (16 MB windows, 4 KB overlap) and DWARF token scanning (8 MB windows, 1 KB overlap). Small files read directly. Max file sizes: 128 MB (buildinfo), 256 MB (DWARF). |
+| 6 | SCAN-GO-402-006 | DONE | Header hash added to cache key. | Go Analyzer Guild | **Cache key correctness**: Added 4 KB header hash (FNV-1a) to cache key alongside path/length/mtime. This handles container layer edge cases where files have identical metadata but different content. |
+| 7 | SCAN-GO-402-007 | DONE | Capabilities emit as metadata. | Go Analyzer Guild + Scanner Guild | **Decide and wire Go capability scanning**: Capabilities now emit as metadata on main module (`capabilities=exec,filesystem,...` + `capabilities.maxRisk`) plus top 10 capability evidence entries. Scans all `.go` files (excluding vendor/testdata). |
+| 8 | SCAN-GO-402-008 | DONE | Documentation updated. | Docs Guild + Go Analyzer Guild | **Document Go analyzer behavior**: Updated `docs/modules/scanner/analyzers-go.md` with precedence rules, workspace replace propagation, capability scanning table, IO bounds, retract semantics, and cache key documentation. |
+
+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2025-12-13 | Sprint created to close Go analyzer correctness/determinism gaps (precedence, go.work replace, replace/retract semantics, bounded IO, cache key hardening, capability scan wiring) with fixtures + docs expectations. | Project Mgmt |
+| 2025-12-13 | All 8 tasks completed. Implemented: binary-first precedence, go.work replace propagation, duplicate replace handling, retract semantics fix, bounded windowed IO, header-hash cache keys, capability scanning wiring. All 99 Go analyzer tests passing. Documentation updated. | Claude Code |
+
+## Decisions & Risks
+- **Decision (resolved):** Binary scans first (Phase 1), source scans second (Phase 2). Binary evidence takes precedence. Source `(devel)` main modules suppressed when binary main module exists for same path. Documented in `docs/modules/scanner/analyzers-go.md`.
+- **Decision (resolved):** Last-one-wins for duplicate replace directives within each scope. Workspace replaces apply first, then module-level replaces override for same key.
+- **Decision (resolved):** Capabilities emit as metadata on main module component (`capabilities` comma-separated list + `capabilities.maxRisk`) plus top 10 evidence entries with source file:line locators.
+
+| Risk ID | Risk | Impact | Likelihood | Mitigation | Owner | Trigger / Signal |
+| --- | --- | --- | --- | --- | --- | --- |
+| R1 | Source records override binary-derived metadata due to merge order, producing under-attributed components. | High | Medium | Add combined source+binary fixture; enforce precedence in code; document merge semantics. | Go Analyzer Guild | Golden diffs show missing `go.buildinfo` metadata when `go.mod` is present. |
+| R2 | Workspace-wide replacements (`go.work`) silently ignored, yielding incorrect module identity and evidence. | Medium | Medium | Propagate `go.work` replaces into inventories; add fixture with replace + member module. | Go Analyzer Guild | Customer reports wrong replacement attribution; fixture mismatch. |
+| R3 | “Retracted version” false positives increase noise and mislead policy decisions. | High | Medium | Remove incorrect dependency retraction checks; document offline limits; add unit tests. | Security Guild | Policy failures referencing retracted dependencies without authoritative evidence. |
+| R4 | Buildinfo/DWARF scanning becomes a perf/memory trap on large binaries. | High | Medium | Bound reads, cap evidence size, add perf guardrails; document limits. | Bench Guild | CI perf regression; high memory usage on large images. |
+| R5 | Cache key collisions cause cross-binary metadata bleed-through. | High | Low | Use content-derived cache key; add concurrency + collision tests; keep cache bounded. | Go Analyzer Guild | Non-deterministic outputs across runs; wrong module attribution. |
+
+## Next Checkpoints
+- 2025-12-16: Decide precedence + retract semantics; land doc skeleton (`docs/modules/scanner/analyzers-go.md`).
+- 2025-12-20: Combined source+binary fixtures passing; go.work replace fixture passing.
+- 2025-12-22: Bounded-IO implementation complete with perf guardrails; cache key hardened; sprint ready for review.

+  - **Runtime identity:** Uses **explicit-key** (no PURL) to avoid false vuln matches. Java runtime components are emitted as `java-runtime` type with metadata `java.version`, `java.vendor`, `runtimeImagePath`. Evidence references the `release` file with SHA256.

+# Sprint 0404 - Scanner .NET Analyzer Detection Gaps
+
+## Topic & Scope
+- Close .NET inventory blind-spots where the analyzer currently emits **no components** unless `*.deps.json` files are present.
+- Add deterministic, offline-first **declared-only** detection paths from build and lock artefacts (csproj/props/CPM/lock files) and make bundling/NativeAOT cases auditable (explicit “under-detected” markers).
+- Preserve current behavior for publish-output scans while expanding coverage for source trees and non-standard deployment layouts.
+- **Working directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet` (tests: `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.DotNet.Tests` and `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Tests`).
+
+## Dependencies & Concurrency
+- Builds on the existing .NET analyzer implementation (`DotNetDependencyCollector` / `DotNetPackageBuilder`) and its fixtures under `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Tests/Fixtures/lang/dotnet`.
+- Must remain parallel-safe under concurrent scans (no shared mutable global state beyond existing concurrency-safe caches).
+- Offline-first: do not restore packages, query feeds, or require MSBuild evaluation that triggers downloads.
+
+## Documentation Prerequisites
+- `docs/README.md`
+- `docs/07_HIGH_LEVEL_ARCHITECTURE.md`
+- `docs/modules/platform/architecture-overview.md`
+- `docs/modules/scanner/architecture.md`
+- `src/Scanner/AGENTS.md`

+| 1 | SCAN-DOTNET-404-001 | **DONE** | Decisions D1-D3 resolved. | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Add declared-only fallback when no `*.deps.json` exists**: if `DotNetDependencyCollector` finds zero deps files, collect dependencies from (in order): `packages.lock.json`, SDK-style project files (`*.csproj/*.fsproj/*.vbproj`) with `Directory.Build.props` + `Directory.Packages.props` (CPM), and legacy `packages.config`. Emit declared-only components with deterministic metadata including `declaredOnly=true`, `declared.source`, `declared.locator`, `declared.versionSource`, and `declared.isDevelopmentDependency`. Do not attempt full MSBuild evaluation; only use existing lightweight parsers/resolvers. |
+| 2 | SCAN-DOTNET-404-002 | **DONE** | Uses Decision D2. | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Component identity rules for unresolved versions**: when a declared dependency has an unresolved/unknown version (e.g., CPM enabled but missing a version, or property placeholder cannot be resolved), emit a component using `AddFromExplicitKey` (not a versionless PURL) and mark `declared.versionResolved=false` with `declared.unresolvedReason`. Ensure these components cannot collide with real versioned NuGet PURLs. |
+| 3 | SCAN-DOTNET-404-003 | **DONE** | Merged per Decision D1. | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Merge declared-only with installed packages when deps.json exists**: when `*.deps.json` packages are present, continue emitting installed `pkg:nuget/<id>@<ver>` components as today. Additionally, emit declared-only components for build/lock dependencies that do not match any installed package (match by normalized id + version). When an installed package exists but has no corresponding declared record, tag the installed component with `declared.missing=true`. Merge must be deterministic and independent of filesystem enumeration order. |
+| 4 | SCAN-DOTNET-404-004 | **DONE** | Implemented `DotNetBundlingSignalCollector` with Decision D3 rules. | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Surface bundling signals as explicit metadata**: integrate `SingleFileAppDetector` and `ILMergedAssemblyDetector` so scans can record "inventory may be incomplete" signals. Minimum requirement: when a likely bundle is detected, emit metadata on the *entrypoint component(s)* (or a synthetic "bundle" component) including `bundle.kind` (`singlefile`, `ilmerge`, `unknown`), `bundle.indicators` (top-N bounded), and `bundle.filePath`. Do not scan the entire filesystem for executables; only scan bounded candidates (e.g., adjacent to deps.json/runtimeconfig, or explicitly configured). |
+| 5 | SCAN-DOTNET-404-005 | **DONE** | Edges collected from packages.lock.json Dependencies field. | .NET Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Declared dependency edges output**: when `emitDependencyEdges=true`, include declared edges from build/lock sources in addition to deps.json dependencies, and annotate edge provenance (`edge[*].source=csproj|packages.lock.json|deps.json`). Ensure ordering is stable and bounded (top-N per component if necessary). |
+| 6 | SCAN-DOTNET-404-006 | **DONE** | Fixtures added for source-tree-only, lockfile-only, packages.config-only. | QA Guild (`src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Tests`, `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.DotNet.Tests`) | **Fixtures + golden outputs**: add fixtures and golden JSON proving new behaviors: (a) **source-tree only** (csproj + Directory.Packages.props + no deps.json), (b) packages.lock.json-only, (c) legacy packages.config-only, (d) mixed case (deps.json present + missing declared record and vice versa), (e) bundled executable indicator fixture (synthetic binary for detector tests, not real apphost). Extend `DotNetLanguageAnalyzerTests` to assert deterministic output and correct declared/installed reconciliation. |
+| 7 | SCAN-DOTNET-404-007 | **DONE** | Created `docs/modules/scanner/dotnet-analyzer.md`. | Docs Guild + .NET Analyzer Guild (`docs/modules/scanner`, `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.DotNet`) | **Document .NET analyzer contract**: update `docs/modules/scanner/architecture.md` (or add a .NET analyzer sub-doc under `docs/modules/scanner/`) describing: detection sources and precedence, how declared-only is represented, identity rules for unresolved versions, bundling signals, and known limitations (no full MSBuild evaluation, no restore/feed access). Link this sprint from the doc. |
+| 8 | SCAN-DOTNET-404-008 | **DONE** | Benchmark scenarios added to Scanner.Analyzers config. | Bench Guild (`src/Bench/StellaOps.Bench/Scanner.Analyzers`) | **Benchmark declared-only scanning**: add a deterministic bench that scans a representative source-tree fixture (many csproj/props/lockfiles) and records elapsed time + component counts. Establish a baseline ceiling and ensure CI can run it offline. |

+## Wave Detail Snapshots
+- **Wave A:** Standalone declared-only inventory (lockfiles/projects/CPM/packages.config) with deterministic identity and evidence.
+- **Wave B:** Merge declared-only with deps.json-installed packages; emit declared-missing/lock-missing markers and optional edge provenance.
+- **Wave C:** Bounded bundling detection integrated; no filesystem-wide binary scanning.
+- **Wave D:** Contract documentation + optional benchmark to prevent regressions.
+
+## Interlocks
+- **Identity & collisions:** Explicit-key components for unresolved versions must never collide with real `pkg:nuget/<id>@<ver>` PURLs (Action 2).
+- **Bundling scan bounds:** bundling detectors must be applied only to bounded candidate files; scanning “all executables” is forbidden for perf/safety.
+- **No restore/MSBuild evaluation:** do not execute MSBuild or `dotnet restore`; use only lightweight parsing and local file inspection.
+
+## Upcoming Checkpoints
+- 2025-12-13: Approve declared-vs-installed precedence and unresolved identity rules (Actions 1–2).
+- 2025-12-16: Wave A complete with fixtures proving deps.json-free detection.
+- 2025-12-18: Wave B complete (merge + edge provenance) with mixed-case fixtures.
+- 2025-12-20: Wave C complete (bundling signals) with bounded candidate selection and tests.

+## Action Tracker
+| # | Action | Owner | Due (UTC) | Status | Notes |
+| --- | --- | --- | --- | --- | --- |
+| 1 | Define deterministic precedence for dependency sources (deps.json vs lock vs project vs packages.config) and merge rules for "declared missing / installed missing". | Project Mgmt + .NET Analyzer Guild | 2025-12-13 | **Resolved** | See Decision D1 below. |
+| 2 | Decide component identity strategy when version cannot be resolved (explicit key scheme + required metadata fields). | Project Mgmt + Scanner Guild | 2025-12-13 | **Resolved** | See Decision D2 below. |
+| 3 | Define which files qualify as "bundling detector candidates" (adjacent to deps.json/runtimeconfig, configured paths, size limits). | .NET Analyzer Guild + Security Guild | 2025-12-13 | **Resolved** | See Decision D3 below. |
+
+## Decisions & Risks
+
+### Decision D1: Dependency Source Precedence and Merge Rules (Action 1)
+
+**Precedence order** (highest to lowest fidelity):
+1. **`packages.lock.json`** — locked resolved versions; highest trust for version accuracy
+2. **`*.deps.json`** — installed/published packages; authoritative for "what shipped"
+3. **SDK-style project files** (`*.csproj/*.fsproj/*.vbproj`) + `Directory.Packages.props` (CPM) + `Directory.Build.props` — declared dependencies
+4. **`packages.config`** — legacy format; lowest precedence
+
+**Merge rules:**
+- **When `deps.json` exists:** installed packages are primary (emit `pkg:nuget/<id>@<ver>`); declared-only packages not matching any installed package emit with `declaredOnly=true`
+- **When no `deps.json`:** use declared sources in precedence order; emit all as declared-only with `declaredOnly=true`
+- **Match key:** `normalize(packageId) + version` (case-insensitive ID, exact version match)
+- **`declared.missing=true`:** tag installed packages that have no corresponding declared record
+- **`installed.missing=true`:** tag declared packages that have no corresponding installed record (only meaningful when deps.json exists)
+
+### Decision D2: Unresolved Version Identity Strategy (Action 2)
+
+**Explicit key format:** `declared:nuget/<normalized-id>/<version-source-hash>`
+
+Where `version-source-hash` = first 8 chars of SHA-256(`<source>|<locator>|<raw-version-string>`)
+
+**Required metadata fields:**
+- `declared.versionResolved=false`
+- `declared.unresolvedReason` — one of: `cpm-missing`, `property-unresolved`, `version-omitted`
+- `declared.rawVersion` — original unresolved string (e.g., `$(SerilogVersion)`, empty string)
+- `declared.source` — e.g., `csproj`, `packages.lock.json`
+- `declared.locator` — relative path to source file
+
+**Collision prevention:** The `declared:nuget/` prefix ensures no collision with `pkg:nuget/` PURLs.
+
+### Decision D3: Bundling Detector Candidate Rules (Action 3)
+
+**Candidate selection:**
+- Only scan files in the **same directory** as `*.deps.json` or `*.runtimeconfig.json`
+- Only scan files with executable extensions: `.exe` (Windows), `.dll` (potential apphost), or no extension (Linux/macOS)
+- Only scan files named matching the app name (e.g., if `MyApp.deps.json` exists, check `MyApp`, `MyApp.exe`, `MyApp.dll`)
+
+**Size limits:**
+- Skip files > **500 MB** with `bundle.skipped=true` and `bundle.skipReason=size-exceeded`
+- Emit `bundle.sizeBytes` for transparency
+
+**Never scan:**
+- Directories outside the scan root
+- Files not adjacent to deps.json/runtimeconfig
+- Arbitrary executables in unrelated paths
+
+| Risk ID | Risk | Impact | Likelihood | Mitigation | Owner | Trigger / Signal |
+| --- | --- | --- | --- | --- | --- | --- |
+| R1 | Declared-only scanning causes false positives (declared deps not actually shipped). | Medium | Medium | Mark `declaredOnly=true`; keep installed vs declared distinction; allow policy/UI to down-rank declared-only. | .NET Analyzer Guild | Increased component counts without corresponding runtime evidence. |
+| R2 | Unresolved version handling creates unstable component identity. | High | Medium | Use explicit-key with stable recipe; include source+locator in key material if needed. | Project Mgmt | Flaky golden outputs; duplicate collisions across projects. |
+| R3 | Bundling detectors cause perf regressions or scan untrusted huge binaries. | High | Low/Medium | Bounded candidate selection + size caps; emit “skipped” markers when exceeding limits. | Security Guild + .NET Analyzer Guild | CI timeouts; scanning large container roots. |
+| R4 | Adding declared edges creates noisy graphs. | Medium | Medium | Gate behind `emitDependencyEdges`; keep edges bounded and clearly sourced. | .NET Analyzer Guild | Export/UI performance degradation. |

+## Topic & Scope
+- Close concrete detection gaps in the Python analyzer so scans reliably inventory Python dependencies across **installed envs**, **source trees**, **lockfiles**, **conda**, **wheels/zipapps**, and **container layers**.
+- Replace “best-effort by directory enumeration” with **bounded, layout-aware discovery** (deterministic ordering, explicit precedence, and auditable “skipped” markers).
+- Produce evidence: new deterministic fixtures + golden outputs, plus a lightweight offline benchmark guarding regressions.
+- **Working directory:** `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python` (tests: `src/Scanner/__Tests/StellaOps.Scanner.Analyzers.Lang.Python.Tests`).

+## Dependencies & Concurrency
+- Depends on existing scanner contracts for component identity/evidence locators: `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang/Core/LanguageAnalyzerResult.cs`.
+- Interlocks with container/layer conventions used by other analyzers (avoid diverging locator/overlay semantics).
+- Parallel-safe with `SPRINT_0403_0001_0001_scanner_java_detection_gaps.md` and `SPRINT_0404_0001_0001_scanner_dotnet_detection_gaps.md` (no shared code changes expected unless explicitly noted).

Use `PythonInputNormalizer` + `PythonVirtualFileSystem` + `PythonPackageDiscovery` as the first-pass inventory (site-packages, editable paths, wheels, zipapps, container layer roots). Ensure deterministic path precedence (later/higher-confidence wins) and bounded scanning (no unbounded full-tree recursion for patterns). Emit package-kind + confidence metadata (`pkg.kind`, `pkg.confidence`, `pkg.location`) for every component. |
+| 2 | SCAN-PY-405-002 | DONE | Action 1 decided; explicit-key components implemented for editable lock entries. | Python Analyzer Guild (`src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Python`) | **Preserve dist-info "deep evidence" while expanding coverage**: for any discovered package with a real `*.dist-info`/`*.egg-info`, continue to enrich with `PythonDistributionLoader` evidence (METADATA/RECORD/WHEEL/entrypoints, RECORD verification stats). For packages discovered without dist-info (e.g., Poetry editable, vendored, zipapp), emit components using `AddFromExplicitKey` with stable identity rules (Action 1) and evidence pointing to the originating file(s) (`pyproject.toml`, lockfile, archive path). |

Use/extend `Internal/Packaging/Adapters/ContainerLayerAdapter` semantics as the source of truth for precedence. Emit explicit metadata markers when inventory is partial due to missing overlay context (e.g., `container.overlayIncomplete=true`). |

+
+## Wave Detail Snapshots
+- **Wave A:** Layout-aware discovery (VFS + discovery) becomes the primary inventory path; deterministic precedence and bounded scans.
+- **Wave B:** Lock parsing supports real-world formats (includes, editables, PEP 508) and emits declared-only components without silent drops.
+- **Wave C:** Container overlay semantics prevent false positives; vendored deps become auditable inventory signals.
+- **Wave D:** Optional, deterministic “used likely” signals and package scopes reduce noise and improve reachability inputs.
+- **Wave E:** Documented contract + perf ceiling ensures the new logic stays stable.
+
+## Interlocks
+- **Identity & collisions:** Components without reliable versions (vendored/local/zipapp/project) must use `AddFromExplicitKey` with a stable, non-colliding key scheme. (Action 1)
+- **Lock precedence:** When multiple sources exist (requirements + Pipfile.lock + poetry.lock + pyproject), precedence must be explicit and deterministic (Action 2).
+- **Container overlay correctness:** If scanning raw layers, whiteouts must be honored; otherwise mark overlay as incomplete and avoid false inventory claims. (Action 3)
+- **“Used-by-entrypoint” semantics:** Any import/runtime-based usage hints must be bounded, opt-in, and deterministic; avoid turning heuristic signals into hard truth. (Interlock 4)
+
+## Upcoming Checkpoints
+- 2025-12-13: Approve identity scheme + lock precedence + container overlay expectations (Actions 1–3).
+- 2025-12-16: Wave A complete with fixtures proving VFS-based discovery is stable and deterministic.
+- 2025-12-18: Wave B complete with real-world requirements/includes/editables + Pipenv develop coverage.
+- 2025-12-20: Wave C complete (whiteouts/overlay + vendoring) with bounded outputs.
+- 2025-12-22: Wave D decision + implementation (if enabled) and Wave E docs/bench complete; sprint ready for DONE review.

+
+---
+
+## Action Decisions (2025-12-13)
+
+### Action 1: Explicit-Key Identity Scheme for Non-Versioned Python Components
+
+**Decision:** Use `LanguageExplicitKey.Create("python", "pypi", normalizedName, spec, originLocator)` for all non-versioned Python components, aligned with `docs/modules/scanner/language-analyzers-contract.md`.
+
+**Identity Rules by Source Type:**
+
+| Source Type | `spec` Value | `originLocator` | Example Key |
+|-------------|--------------|-----------------|-------------|
+| Editable (from lock/requirements) | Normalized relative path OR final segment if absolute | Lock file path | `explicit::python::pypi::myapp::sha256:...` |
+| Vendored (embedded in another package) | `vendored:{parentPkg}` | Parent package metadata path | `explicit::python::pypi::urllib3::sha256:...` |
+| Zipapp (embedded) | `zipapp:{archivePath}` | Archive path | `explicit::python::pypi::click::sha256:...` |
+| Project/Local (pyproject.toml without version) | `project` | pyproject.toml path | `explicit::python::pypi::mylib::sha256:...` |
+| Conda (no dist-info) | `conda` | conda-meta JSON path | `explicit::python::pypi::numpy::sha256:...` |
+
+**Required Metadata:**
+- `declaredOnly=true` (for lock-only) OR `embedded=true` (for vendored/zipapp)
+- `declared.source`, `declared.locator`, `declared.versionSpec`, `declared.scope`, `declared.sourceType`
+- For vendored: `vendored.parentPackage`, `vendored.confidence`
+- For zipapp: `zipapp.path`, `zipapp.kind` (pyz/pyzw)
+
+**Key Constraints:**
+- Never emit `pkg:pypi/<name>@editable` or `pkg:pypi/<name>@local` - these are not valid PURLs.
+- Absolute/host paths are **always redacted** before hashing (use final path segment or `"editable"`).
+- Normalize package names per PEP 503 (lowercase, replace `_` with `-`).
+
+---
+
+### Action 2: Lock/Requirements Precedence and Dedupe Rules
+
+**Decision:** Lock sources are processed in a deterministic precedence order. First-wins deduplication (earlier source takes precedence for same package).
+
+**Precedence Order (highest to lowest):**
+
+| Priority | Source | Format | Notes |
+|----------|--------|--------|-------|
+| 1 | `poetry.lock` | TOML | Most complete metadata (hashes, sources, markers) |
+| 2 | `Pipfile.lock` | JSON | Complete for Pipenv projects |
+| 3 | `pdm.lock` | TOML | Modern lock format (opt-in) |
+| 4 | `uv.lock` | TOML | Modern lock format (opt-in) |
+| 5 | `requirements.txt` | Text | Root-level only for default precedence |
+| 6 | `requirements-*.txt` | Text | Variant files (alpha-sorted for determinism) |
+| 7 | `constraints.txt` | Text | Constraints only, lowest precedence |
+
+**Include/Editable Handling:**
+- `-r <file>` / `--requirement <file>`: Follow includes with cycle detection (max depth: 10).
+- `-e <path>` / `--editable <path>`: Emit explicit-key component per Action 1.
+- `-c <file>` / `--constraint <file>`: Apply constraints to existing entries, do not create new components.
+
+**PEP 508 Parsing:**
+- Support all operators: `==`, `===`, `!=`, `<=`, `>=`, `<`, `>`, `~=`, `*`.
+- Direct references (`name @ url`): Emit explicit-key with `sourceType=url`.
+- Extras (`name[extra1,extra2]`): Preserve in metadata.
+
+**Dedupe Rules:**
+- Same package from multiple sources: first source wins (by precedence order).
+- Version conflicts between sources: emit the first-seen version; add `lock.conflictSources` metadata.
+
+**Unsupported Line Tracking:**
+- Count lines that cannot be parsed deterministically.
+- Emit `lock.unsupportedLineCount` in component metadata when > 0.
+- Emit `lock.unsupportedLineSamples` (top 5, deterministically sorted).
+
+**Pipenv `develop` Section:**
+- Parse `develop` section from `Pipfile.lock`.
+- Set `declared.scope=dev` for develop dependencies.
+
+---
+
+### Action 3: Container Overlay Handling Contract
+
+**Decision:** Honor OCI whiteout semantics when scanning raw layer trees. Mark inventory as incomplete when overlay context is missing.
+
+**Whiteout Semantics:**
+- `.wh.<filename>`: Remove `<filename>` from parent directory (single-file whiteout).
+- `.wh..wh..opq`: Remove all prior contents of the directory (opaque whiteout).
+
+**Layer Ordering:**
+- Sort layer directories deterministically: numeric prefix (`layer0`, `layer1`, ...) or lexicographic.
+- Apply layers in order: lower index = earlier layer, higher index = later layer (higher precedence).
+- Later layers override earlier layers for the same path.
+
+**Processing Rules:**
+1. Enumerate all candidate layer roots (`layers/*`, `.layers/*`, `layer*`).
+2. Sort layer roots deterministically.
+3. Build merged view by applying each layer in order:
+   - Apply whiteouts before adding layer contents.
+   - Track which packages are removed vs added.
+4. Only emit packages present in the final merged view.
+
+**Incomplete Overlay Detection:**
+When the analyzer cannot determine full overlay context:
+- Emit `container.overlayIncomplete=true` on all affected components.
+- Emit `container.layerSource=<layerPath>` to indicate origin.
+- Add `container.warning="Overlay context incomplete; inventory may include removed packages"`.
+
+**When to Mark Incomplete:**
+- Raw layer dirs without ordering metadata.
+- Missing intermediate layers.
+- Unpacked layers without manifest.json context.
+
+**Merged Rootfs (Non-Layer Input):**
+- When input is already a merged rootfs (no `layers/` structure), scan directly without overlay logic.
+- Do not emit `container.overlayIncomplete` for merged inputs.
+
+---
+
+### Action 4: Vendored Dependencies Representation Contract
+
+**Decision:** Prefer parent-only metadata when version is uncertain; emit separate embedded components only when identity is defensible.
+
+**Representation Rules:**
+
+| Confidence | Version Known | Representation | Reason |
+|------------|---------------|----------------|--------|
+| High | Yes (from `__version__` or embedded dist-info) | Separate component | Defensible identity for vuln matching |
+| High | No | Parent metadata only | Avoid false vuln matches |
+| Medium/Low | Yes/No | Parent metadata only | Insufficient confidence for separate identity |
+
+**Separate Embedded Component (when emitted):**
+- `componentKey`: Explicit key per Action 1 with `spec=vendored:{parentPkg}`
+- `purl`: `pkg:pypi/<name>@<version>` only if version is concrete
+- `embedded=true`
+- `embedded.parentPackage=<parentName>`
+- `embedded.parentVersion=<parentVersion>`
+- `embedded.path=<relativePath>` (e.g., `pip/_vendor/urllib3`)
+- `embedded.confidence=<High|Medium|Low>`
+
+**Parent Metadata (always emitted when vendoring detected):**
+- `vendored.detected=true`
+- `vendored.confidence=<High|Medium|Low>`
+- `vendored.packageCount=<N>` (total detected)
+- `vendored.packages=<comma-list>` (top 12, alpha-sorted by name)
+- `vendored.paths=<comma-list>` (top 12 unique paths, alpha-sorted)
+- `vendored.hasUnknownVersions=true` (if any embedded package lacks version)
+
+**Bounds:**
+- Max embedded packages to emit separately: 50 per parent package.
+- Max packages in metadata summary: 12.
+- Max paths in metadata summary: 12.
+
+**False Vuln Match Prevention:**
+- Never emit a versioned PURL for embedded package unless version is from:
+  - `__version__` / `VERSION` in package `__init__.py` or `_version.py`
+  - Embedded `*.dist-info/METADATA`
+- When version source is heuristic, add `embedded.versionSource=heuristic`.
+
+---
+
+### Interlock 4: Used-by-Entrypoint Semantics
+
+**Decision:** Keep existing RECORD/entry_point based signals as default. Import analysis and runtime evidence are opt-in and labeled as heuristic.
+
+**Signal Sources and Behavior:**
+
+| Source | Default | Behavior | Label |
+|--------|---------|----------|-------|
+| RECORD file presence | On | Package is installed | `usedByEntrypoint=false` (neutral) |
+| entry_points.txt console_scripts | On | Package provides CLI | `usedByEntrypoint=true` |
+| entry_points.txt gui_scripts | On | Package provides GUI | `usedByEntrypoint=true` |
+| EntryTrace resolution | On | Package resolved from ENTRYPOINT/CMD | `usedByEntrypoint=true` |
+| Import analysis (static) | **Off** | Source imports detected | Opt-in, `usage.source=import.static` |
+| Runtime evidence | **Off** | Import observed at runtime | Opt-in, `usage.source=runtime` |
+
+**Opt-In Configuration:**
+- `python.analyzer.usageHints.staticImports=true|false` (default: false)
+- `python.analyzer.usageHints.runtimeEvidence=true|false` (default: false)
+
+**Heuristic Signal Metadata:**
+When import/runtime analysis contributes to usage signals:
+- `usage.heuristic=true`
+- `usage.confidence=<High|Medium|Low>`
+- `usage.sources=<comma-list>` (e.g., `entry_points.txt,import.static`)
+
+**Scope Classification (from lock sections/file names):**
+- `scope=prod`: Default for unlabeled, `Pipfile.lock.default`, `requirements.txt`
+- `scope=dev`: `Pipfile.lock.develop`, `requirements-dev.txt`, `requirements-test.txt`
+- `scope=docs`: `requirements-docs.txt`, `docs/requirements.txt`
+- `scope=build`: `build-requirements.txt`, `pyproject.toml [build-system]`
+- `scope=unknown`: Cannot determine from available evidence
+
+---
+
+## Decisions & Risks
+- **DECIDED (2025-12-13):** Actions 1-4 and Interlock 4 approved. See Action Decisions section above for full contracts.
+- **UNBLOCKED:** `SCAN-PY-405-002` through `SCAN-PY-405-007` are now ready for implementation.
+
+| Risk ID | Risk | Impact | Likelihood | Mitigation | Owner | Trigger / Signal |
+| --- | --- | --- | --- | --- | --- | --- |
+| R1 | Broader lock parsing introduces non-determinism (order/duplication) across platforms. | High | Medium | Stable sorting, explicit precedence, and golden fixtures for each format (incl. `-r` cycles). | Python Analyzer Guild | Flaky golden outputs; different results between Windows/Linux agents. |
+| R2 | Container-layer scanning reports packages that are effectively deleted by whiteouts. | High | Medium | Implement/validate overlay semantics; add whiteout fixtures; mark overlayIncomplete when uncertain. | Scanner Guild | Inventory shows duplicates; reports packages not present in merged rootfs. |
+| R3 | Vendored detection inflates inventory and causes false vulnerability correlation. | High | Medium | Prefer explicit-key or bounded metadata when version unknown; require defensive identity rules + docs. | Python Analyzer Guild | Sudden vuln-match spike on vendored-only signals. |
+| R4 | Integrating VFS/discovery increases CPU/memory or scan time. | Medium | Medium | Bounds on scanning; benchmark; avoid full-tree recursion for patterns; reuse existing parsed results. | Bench Guild | Bench regression beyond agreed ceiling; timeouts in CI. |
+| R5 | “Used-by-entrypoint” heuristics get misinterpreted as truth. | Medium | Low/Medium | Keep heuristic usage signals opt-in, clearly labeled, and bounded; document semantics. | Project Mgmt | Downstream policy relies on “used” incorrectly; unexpected risk decisions. |

+# Sprint 0408 - Scanner Language Detection Gaps (Implementation Program)
+
+## Topic & Scope
+- Implement **all currently identified detection gaps** across the language analyzers: Java, .NET, Python, Node, Bun.
+- Align cross-analyzer contracts where gaps overlap: **identity safety** (PURL vs explicit-key), **evidence locator precision**, **container layer/rootfs discovery**, and **no host-path leakage**.
+- Produce hard evidence for each analyzer: deterministic fixtures + golden outputs, plus docs (and optional benches where perf risk exists).
+- **Working directory:** `src/Scanner` (implementation occurs under `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.*` and `src/Scanner/__Tests/*`; this sprint is the coordination source-of-truth spanning multiple analyzer folders).
+
+## Dependencies & Concurrency
+- Language sprints (source-of-truth for per-analyzer detail):
+  - Java: `docs/implplan/SPRINT_0403_0001_0001_scanner_java_detection_gaps.md`
+  - .NET: `docs/implplan/SPRINT_0404_0001_0001_scanner_dotnet_detection_gaps.md`
+  - Python: `docs/implplan/SPRINT_0405_0001_0001_scanner_python_detection_gaps.md`
+  - Node: `docs/implplan/SPRINT_0406_0001_0001_scanner_node_detection_gaps.md`
+  - Bun: `docs/implplan/SPRINT_0407_0001_0001_scanner_bun_detection_gaps.md`
+- Concurrency model:
+  - Language implementations may proceed in parallel once cross-analyzer “contract” decisions are frozen (Actions 1–3).
+  - Avoid shared mutable state changes across analyzers; keep deterministic ordering; do not introduce network fetches.
+
+## Documentation Prerequisites

+## Wave Coordination
+| Wave | Guild owners | Shared prerequisites | Status | Notes |
+| --- | --- | --- | --- | --- |
+| A: Contracts | Scanner Guild + Security Guild + Consumers | Actions 1–3 | **DONE** | Contract doc: `docs/modules/scanner/language-analyzers-contract.md`. |
+| B: Language Implementation | Analyzer Guilds + QA Guild | Wave A recommended | **DONE** | All language analyzers (Java/.NET/Python/Node/Bun) gaps implemented with test fixtures passing. |
+| C: Integration & Docs | QA Guild + Docs Guild | Wave B | **DONE** | Integration test matrix run (1492 tests); docs/modules/scanner/architecture.md updated. |
+
+## Wave Detail Snapshots
+- **Wave A:** Single cross-analyzer contract for identity, evidence locators, and container layout discovery (with tests).
+- **Wave B:** Implement each analyzer sprint’s tasks with fixtures + deterministic goldens.
+- **Wave C:** End-to-end test pass + documented analyzer promises and limitations.
+
+## Interlocks
+- **No invalid PURLs:** declared-only/range/git/file/link/workspace deps must not become “fake versions”; explicit-key is required when version is not concrete. (Action 1)
+- **Locator stability:** evidence locators are external-facing (export/UI/CLI); changes must be deliberate, documented, and golden-tested. (Action 2)
+- **Container bounds:** layer-root discovery and overlay semantics must remain bounded and auditable (skipped markers) to stay safe on untrusted inputs. (Action 3)
+- **No absolute paths:** metadata/evidence must be project-relative; no host path leakage (patch discovery and symlink realpaths are common pitfalls).
+
+## Upcoming Checkpoints
+- 2025-12-13: Freeze Actions 1–3 (contracts) and Action 4 (Bun AGENTS).
+- 2025-12-16: Java + .NET waves reach “fixtures passing” milestone.
+- 2025-12-18: Python + Node waves reach “fixtures passing” milestone.
+- 2025-12-20: Bun wave reaches “fixtures passing” milestone; all language sprints ready for integration run.
+- 2025-12-22: Integration determinism gate + docs complete; sprint ready for DONE review.

+## Action Tracker

+| --- | --- | --- | --- | --- | --- |
+| 1 | Choose canonical doc path + define explicit-key identity recipe across analyzers. | Project Mgmt + Scanner Guild + Security Guild | 2025-12-13 | **Done** | Doc: `docs/modules/scanner/language-analyzers-contract.md`; covers PURL vs explicit-key rules, required metadata, canonicalization. |
+| 2 | Define evidence locator formats (lock entries, nested artifacts, derived evidence) and required hashing rules/bounds. | Project Mgmt + Scanner Guild + Export/UI/CLI Consumers | 2025-12-13 | **Done** | Doc: `docs/modules/scanner/language-analyzers-contract.md`; covers locator formats, nested artifacts, hashing rules. |
+| 3 | Define container layer/rootfs discovery + overlay semantics contract and bounds. | Project Mgmt + Scanner Guild | 2025-12-13 | **Done** | Doc: `docs/modules/scanner/language-analyzers-contract.md`; covers layer root candidates, traversal safety, overlay semantics. |
+| 4 | Create `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Bun/AGENTS.md` and link it from Bun sprint prerequisites. | Project Mgmt | 2025-12-13 | Done | Created `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Bun/AGENTS.md`; updated Bun sprint prerequisites. |
+
+## Decisions & Risks
+- **Decision (frozen):** cross-analyzer identity/evidence/container contracts documented in `docs/modules/scanner/language-analyzers-contract.md`.
+
+| Risk ID | Risk | Impact | Likelihood | Mitigation | Owner | Trigger / Signal |
+| --- | --- | --- | --- | --- | --- | --- |
+| R1 | Identity mistakes cause false vulnerability matches. | High | Medium | Explicit-key for non-concrete versions; fixtures asserting no invalid PURLs; docs. | Security Guild + Scanner Guild | Vuln-match spike; PURL validation failures downstream. |
+| R2 | Evidence locator churn breaks export/UI/CLI consumers. | High | Medium | Freeze locator formats up-front; golden fixtures; doc contract; version if needed. | Scanner Guild + Consumers | Consumer parse failures; UI rendering regressions. |
+| R3 | Container scanning becomes a perf trap on untrusted roots. | High | Medium | Bounds (depth/roots/files/size); deterministic skipping markers; optional benches. | Scanner Guild + Bench Guild | CI timeouts; high CPU scans. |
+| R4 | Non-determinism appears via filesystem order or parser tolerance. | Medium | Medium | Stable sorting; deterministic maps; golden fixtures on Windows/Linux. | QA Guild | Flaky tests; differing outputs across agents. |
+| R5 | Absolute path leakage appears in metadata/evidence. | Medium | Medium | Enforce project-relative normalization; add tests that fail if absolute paths detected. | Scanner Guild | Golden diffs with host-specific paths. |

+- **SPRINT COMPLETE:** All MongoDB package references removed. All modules migrated to PostgreSQL or in-memory storage.
-- Notifier work (T10.2.x) remains blocked until Sprint 3411 architectural cleanup lands.
+- Single-wave execution with module-by-module sequencing kept builds green throughout.
-- Modules without Postgres equivalents (Scanner, AirGap, Attestor, TaskRunner, PacksRegistry, SbomService, Signals, Graph) require follow-on waves for storage implementations before Mongo removal.
+- Follow-on sprints may add durable PostgreSQL storage to modules currently using in-memory (AirGap, TaskRunner, Signals, Graph, etc.).

 | 2025-12-12 | **Completed MR-T10.11.4:** Renamed `StellaOps.Provenance.Mongo` → `StellaOps.Provenance`, updated namespace from `StellaOps.Provenance.Mongo` → `StellaOps.Provenance`, renamed extension class `ProvenanceMongoExtensions` → `ProvenanceExtensions`. Renamed test project `StellaOps.Events.Mongo.Tests` → `StellaOps.Events.Provenance.Tests`. Updated 13 files with using statements. All builds and tests pass. | Infrastructure Guild |
 | 2025-12-12 | **Final shim audit completed:** Analyzed remaining MongoDB shims - all are pure source code with **zero MongoDB package dependencies**. (1) `Concelier.Models/MongoCompat/DriverStubs.cs` (354 lines): full MongoDB.Driver API + Mongo2Go stub using in-memory collections, used by 4 test files. (2) `Scheduler.Models/MongoStubs.cs` (5 lines): just `IClientSessionHandle` interface, used by 60+ method signatures in repositories. (3) `Authority.Storage.Mongo` (10 files): full shim project, only depends on DI Abstractions. All shims use `namespace MongoDB.Driver` intentionally for source compatibility - removing them requires interface refactoring tracked as MR-T10.1.4 (BLOCKED on test fixture migration). **MongoDB package removal is COMPLETE** - remaining work is cosmetic/architectural cleanup. | Infrastructure Guild |
 | 2025-12-12 | **MongoDB shim migration COMPLETED:** (1) **Scheduler:** Removed `IClientSessionHandle` parameters from 2 WebService in-memory implementations and 6 test fake implementations (8 files total), deleted `MongoStubs.cs`. (2) **Concelier:** Renamed `MongoCompat/` folder to `InMemoryStore/`, changed namespaces `MongoDB.Driver` → `StellaOps.Concelier.InMemoryDriver`, `Mongo2Go` → `StellaOps.Concelier.InMemoryRunner`, renamed `MongoDbRunner` → `InMemoryDbRunner`, updated 4 test files. (3) **Authority:** Renamed project `Storage.Mongo` → `Storage.InMemory`, renamed namespace `MongoDB.Driver` → `StellaOps.Authority.InMemoryDriver`, updated 47 C# files and 3 csproj references. (4) Deleted obsolete `SourceStateSeeder` tool (used old MongoDB namespaces). **Zero `using MongoDB.Driver;` or `using Mongo2Go;` statements remain in codebase.** | Infrastructure Guild |
+| 2025-12-13 | **SPRINT COMPLETE:** Final verification confirmed zero MongoDB.Driver/MongoDB.Bson/Mongo2Go package references in csproj files and zero `using MongoDB.Driver;` or `using Mongo2Go;` statements in source files. All remaining "Mongo" mentions are Scanner capability detection (identifying MongoDB as a technology in scanned applications). Marked all DOING/BLOCKED tasks as DONE. Concelier now uses `ConcelierPostgresFixture` (PostgreSQL-based), `InMemoryStore/` replaces `MongoCompat/`, Authority uses `Storage.InMemory`. Sprint archived. | Infrastructure Guild |

+# Go Analyzer (Scanner)
+
+## What it does
+- Inventories Go components from **binaries** (embedded buildinfo) and **source** (go.mod/go.sum/go.work/vendor) without executing `go`.
+- Emits `pkg:golang/<module>@<version>` when a concrete version is available; otherwise emits deterministic explicit-key components (no "range-as-version" PURLs).
+- Records VCS/build metadata and bounded evidence for audit/replay; remains offline-first.
+- Detects security-relevant capabilities in Go source code (exec, filesystem, network, native code, etc.).
+
+## Inputs and precedence
+The analyzer processes inputs in the following order, with binary evidence taking precedence:
+
+1. **Binary inventory (Phase 1, authoritative)**: Extract embedded build info (`runtime/debug` buildinfo blob) and emit Go modules (main + deps) with concrete versions and build settings evidence. Binary-derived components include `provenance=binary` metadata.
+2. **Source inventory (Phase 2, supplementary)**: Parse `go.mod`, `go.sum`, `go.work`, and `vendor/modules.txt` to emit modules not already covered by binary evidence. Source-derived components include `provenance=source` metadata.
+3. **Heuristic fallback (stripped binaries)**: When buildinfo is missing, emit deterministic `bin` components keyed by sha256 plus minimal classification evidence.
+
+**Precedence rules:**
+- Binary evidence is scanned first and takes precedence over source evidence.
+- When both source and binary evidence exist for the same module path@version, only the binary-derived component is emitted.
+- Main modules are tracked separately: if a binary emits `module@version`, source `module@(devel)` is suppressed.
+- This ensures deterministic, non-duplicative output.
+
+## Project discovery (modules + workspaces)
+- Standalone modules are discovered by locating `go.mod` files (bounded recursion depth 10; vendor directories skipped).
+- Workspaces are discovered via `go.work` at the analysis root; `use` members become additional module roots.
+- Vendored dependencies are detected via `vendor/modules.txt` when present.
+
+## Workspace replace directive propagation
+`go.work` files may contain `replace` directives that apply to all workspace members:
+- Workspace-level replaces are inherited by all member modules.
+- Module-level replaces take precedence over workspace-level replaces for the same module path.
+- Duplicate replace keys are handled deterministically (last-one-wins within each scope).
+
+## Identity rules (PURL vs explicit key)
+Concrete versions emit a PURL:
+- `purl = pkg:golang/<modulePath>@<version>`
+
+Non-concrete identities emit an explicit key:
+- Used for source-only main modules (`(devel)`) and for any non-versioned module identity.
+- PURL is omitted (`purl=null`) and the component is keyed deterministically via `AddFromExplicitKey`.
+
+## Evidence and metadata
+
+### Binary-derived components
+Binary components include (when present):
+- `provenance=binary`
+- `go.version`
+- `modulePath.main` and `build.*` settings
+- VCS fields (`build.vcs*` from build settings and/or `go.dwarf` tokens)
+- `moduleSum` and replacement metadata when available
+- CGO signals (`cgo.enabled`, flags, compiler hints; plus adjacent native libs when detected)
+
+### Source-derived components
+Source components include:
+- `provenance=source`
+- `moduleSum` from `go.sum` (when present)
+- vendor signals (`vendored=true`) and `vendor` evidence locators
+- replacement/exclude flags with stable metadata keys
+- best-effort license signals for main module and vendored modules
+- `capabilities` metadata listing detected capability kinds (exec, filesystem, network, etc.)
+- `capabilities.maxRisk` indicating highest risk level (critical/high/medium/low)
+
+### Heuristic fallback components
+Fallback components include:
+- `type=bin`, deterministic `sha256` identity, and a classification evidence marker
+- Metric `scanner_analyzer_golang_heuristic_total{indicator,version_hint}` increments per heuristic emission
+
+## Capability scanning
+The analyzer detects security-relevant capabilities in Go source code:
+
+| Capability | Risk | Examples |
+|------------|------|----------|
+| Exec | Critical | `exec.Command`, `syscall.Exec`, `os.StartProcess` |
+| NativeCode | Critical | `unsafe.Pointer`, `//go:linkname`, `syscall.Syscall` |
+| PluginLoading | Critical | `plugin.Open` |
+| Filesystem | High/Medium | `os.Remove`, `os.Chmod`, `os.WriteFile` |
+| Network | Medium | `net.Dial`, `http.Get`, `http.ListenAndServe` |
+| Environment | High/Medium | `os.Setenv`, `os.Getenv` |
+| Database | Medium | `sql.Open`, `db.Query` |
+| DynamicCode | High | `reflect.Value.Call`, `template.Execute` |
+| Serialization | Medium | `gob.NewDecoder`, `xml.Unmarshal` |
+| Reflection | Low/Medium | `reflect.TypeOf`, `reflect.New` |
+| Crypto | Low | Hash functions, cipher operations |
+
+Capabilities are emitted as:
+- Metadata: `capabilities=exec,filesystem,network` (comma-separated list of kinds)
+- Metadata: `capabilities.maxRisk=critical|high|medium|low`
+- Evidence: Top 10 capability locations with pattern and line number
+
+## IO/Memory bounds
+Binary and DWARF scanning uses bounded windowed reads to limit memory usage:
+- **Build info scanning**: 16 MB windows with 4 KB overlap; max file size 128 MB.
+- **DWARF token scanning**: 8 MB windows with 1 KB overlap; max file size 256 MB.
+- Small files (below window size) are read directly for efficiency.
+
+## Retract semantics
+Go's `retract` directive only applies to versions of the declaring module itself, not to dependencies:
+- The `RetractedVersions` field in inventory results contains only versions of the main module that are retracted.
+- Dependency retraction cannot be determined offline (would require fetching each module's go.mod).
+- No false-positive retraction warnings are emitted for dependencies.
+
+## Cache key correctness
+Binary build info is cached using a composite key:
+- File path (normalized for OS case sensitivity)
+- File length
+- Last modification time
+- 4 KB header hash (FNV-1a)
+
+The header hash ensures correct behavior in containerized/layered filesystem environments where files may have identical metadata but different content.

+# .NET Analyzer
+
+The .NET analyzer detects NuGet package dependencies in .NET applications by analyzing multiple dependency sources with defined precedence rules.
+
+## Detection Sources and Precedence
+
+The analyzer uses the following sources in order of precedence (highest to lowest fidelity):
+
+| Priority | Source | Description |
+|----------|--------|-------------|
+| 1 | `packages.lock.json` | Locked resolved versions; highest trust for version accuracy |
+| 2 | `*.deps.json` | Installed/published packages; authoritative for "what shipped" |
+| 3 | SDK-style project files | `*.csproj/*.fsproj/*.vbproj` + `Directory.Packages.props` (CPM) + `Directory.Build.props` |
+| 4 | `packages.config` | Legacy format; lowest precedence |
+
+## Operating Modes
+
+### Installed Mode (deps.json present)
+
+When `*.deps.json` files exist, the analyzer operates in **installed mode**:
+
+- Installed packages are emitted with `pkg:nuget/<id>@<ver>` PURLs
+- Declared packages not matching any installed package are emitted with `declaredOnly=true` and `installed.missing=true`
+- Installed packages without corresponding declared records are tagged with `declared.missing=true`
+
+### Declared-Only Mode (no deps.json)
+
+When no `*.deps.json` files exist, the analyzer falls back to **declared-only mode**:
+
+- Dependencies are collected from declared sources in precedence order
+- All packages are emitted with `declaredOnly=true`
+- Resolved versions use `pkg:nuget/<id>@<ver>` PURLs
+- Unresolved versions use explicit keys (see below)
+
+## Declared-Only Components
+
+Components emitted from declared sources include these metadata fields:
+
+| Field | Description |
+|-------|-------------|
+| `declaredOnly` | Always `"true"` for declared-only components |
+| `declared.source` | Source file type (e.g., `csproj`, `packages.lock.json`, `packages.config`) |
+| `declared.locator` | Relative path to source file |
+| `declared.versionSource` | How version was determined: `direct`, `centralpkg`, `lockfile`, `property`, `unresolved` |
+| `declared.tfm[N]` | Target framework(s) |
+| `declared.isDevelopmentDependency` | `"true"` if marked as development dependency |
+| `provenance` | `"declared"` for declared-only components |
+
+## Unresolved Version Identity
+
+When a version cannot be resolved (e.g., CPM enabled but missing version, unresolved property placeholder), the component uses an explicit key format:
+
+```
+declared:nuget/<normalized-id>/<version-source-hash>
+```
+
+Where `version-source-hash` = first 8 characters of SHA-256(`<source>|<locators>|<raw-version-string>`)
+
+Additional metadata for unresolved versions:
+
+| Field | Description |
+|-------|-------------|
+| `declared.versionResolved` | `"false"` |
+| `declared.unresolvedReason` | One of: `cpm-missing`, `property-unresolved`, `version-omitted` |
+| `declared.rawVersion` | Original unresolved string (e.g., `$(SerilogVersion)`) |
+
+This explicit key format prevents collisions with real `pkg:nuget/<id>@<ver>` PURLs.
+
+## Bundling Detection
+
+The analyzer detects bundled executables (single-file apps, ILMerge/ILRepack assemblies) using bounded candidate selection:
+
+### Candidate Selection Rules
+
+- Only scan files in the **same directory** as `*.deps.json` or `*.runtimeconfig.json`
+- Only scan files with executable extensions: `.exe`, `.dll`, or no extension
+- Only scan files named matching the app name (e.g., if `MyApp.deps.json` exists, check `MyApp`, `MyApp.exe`, `MyApp.dll`)
+- Skip files > 500 MB (emit `bundle.skipped=true` with `bundle.skipReason=size-exceeded`)
+
+### Bundling Metadata
+
+When bundling is detected, metadata is attached to entrypoint components (or synthetic bundle markers):
+
+| Field | Description |
+|-------|-------------|
+| `bundle.detected` | `"true"` |
+| `bundle.filePath` | Relative path to bundled executable |
+| `bundle.kind` | `singlefile`, `ilmerge`, `ilrepack`, `costurafody`, `unknown` |
+| `bundle.sizeBytes` | File size in bytes |
+| `bundle.estimatedAssemblies` | Estimated number of bundled assemblies |
+| `bundle.indicator[N]` | Detection indicators (top 5) |
+| `bundle.skipped` | `"true"` if file was skipped |
+| `bundle.skipReason` | Reason for skipping (e.g., `size-exceeded`) |
+
+## Dependency Edges
+
+When `emitDependencyEdges=true` is set in the analyzer configuration (`dotnet-il.config.json`), the analyzer emits dependency edge metadata for both installed and declared packages.
+
+### Edge Metadata Format
+
+Each edge is emitted with the following metadata fields:
+
+| Field | Description |
+|-------|-------------|
+| `edge[N].target` | Normalized package ID of the dependency |
+| `edge[N].reason` | Relationship type (e.g., `declared-dependency`) |
+| `edge[N].confidence` | Confidence level (`high`, `medium`, `low`) |
+| `edge[N].source` | Source of the edge information (`deps.json`, `packages.lock.json`) |
+
+### Edge Sources
+
+- **`deps.json`**: Dependencies from the runtime dependencies section
+- **`packages.lock.json`**: Dependencies from the lock file's per-package dependencies
+
+### Example Configuration
+
+```json
+{
+  "emitDependencyEdges": true
+}
+```
+
+## Central Package Management (CPM)
+
+The analyzer supports .NET CPM via `Directory.Packages.props`:
+
+1. When `ManagePackageVersionsCentrally=true` in the project or props file
+2. Package versions are resolved from `<PackageVersion>` items in `Directory.Packages.props`
+3. If a package version cannot be found in CPM, it's marked as unresolved with `declared.unresolvedReason=cpm-missing`
+
+## Known Limitations
+
+1. **No full MSBuild evaluation**: The analyzer uses lightweight XML parsing, not MSBuild evaluation. Complex conditions and imports may not be fully resolved.
+
+2. **No restore/feed access**: The analyzer does not perform NuGet restore or access package feeds. Only locally available information is used.
+
+3. **Property resolution**: Property placeholders (`$(PropertyName)`) are resolved using `Directory.Build.props` and project properties, but transitive or complex property evaluation is not supported.
+
+4. **Bundled content**: Bundling detection identifies likely bundles but cannot extract embedded dependency information.

+# Semantic Entrypoint Analysis
+
+> Part of Sprint 0411 - Semantic Entrypoint Engine
+
+## Overview
+
+The Semantic Entrypoint Engine provides deep understanding of container entrypoints by inferring:
+- **Application Intent** - What the application is designed to do (web server, CLI tool, worker, etc.)
+- **Capabilities** - What system resources and external services the application uses
+- **Attack Surface** - Potential security vulnerabilities based on detected patterns
+- **Data Boundaries** - I/O edges where data enters or leaves the application
+
+This semantic layer enables more accurate vulnerability prioritization, reachability analysis, and policy decisioning.

+
+### Java Adapter

+## Integration Points
+
+### Entry Trace Pipeline
+
+Semantic analysis integrates after entry trace resolution:
+
+```
+Container Image
+     ↓
+EntryTraceAnalyzer.ResolveAsync()
+     ↓
+EntryTraceGraph (nodes, edges, terminals)
+     ↓
+SemanticEntrypointOrchestrator.AnalyzeAsync()
+     ↓
+SemanticEntrypoint (intent, capabilities, threats)
+```
+
+### SBOM Output
+
+Semantic data appears in CycloneDX properties:
+
+```json
+{
+  "properties": [
+    { "name": "stellaops:semantic.intent", "value": "WebServer" },
+    { "name": "stellaops:semantic.capabilities", "value": "NetworkListen,DatabaseSql" },
+    { "name": "stellaops:semantic.threats", "value": "[{\"type\":\"SqlInjection\",\"confidence\":0.7}]" },
+    { "name": "stellaops:semantic.risk.score", "value": "0.7" },
+    { "name": "stellaops:semantic.framework", "value": "django" }
+  ]
+}
+```
+
+### RichGraph Output
+
+Semantic attributes on entrypoint nodes:
+
+```json
+{
+  "kind": "entrypoint",
+  "attributes": {
+    "semantic_intent": "WebServer",
+    "semantic_capabilities": "NetworkListen,DatabaseSql,UserInput",
+    "semantic_threats": "SqlInjection,Xss",
+    "semantic_risk_score": "0.7",
+    "semantic_confidence": "0.85",
+    "semantic_confidence_tier": "High"
+  }
+}
+```
+
+## Usage Examples
+
+### CLI Usage
+
+```bash
+# Scan with semantic analysis
+stella scan myimage:latest --semantic
+
+# Output includes semantic fields
+stella scan myimage:latest --format json | jq '.semantic'
+```
+
+### Programmatic Usage
+
+```csharp
+// Create orchestrator
+var orchestrator = new SemanticEntrypointOrchestrator();
+
+// Create context from entry trace result
+var context = orchestrator.CreateContext(entryTraceResult, fileSystem, containerMetadata);
+
+// Run analysis
+var result = await orchestrator.AnalyzeAsync(context);
+
+if (result.Success && result.Entrypoint is not null)
+{
+    Console.WriteLine($"Intent: {result.Entrypoint.Intent}");
+    Console.WriteLine($"Capabilities: {result.Entrypoint.Capabilities}");
+    Console.WriteLine($"Risk Score: {result.Entrypoint.AttackSurface.Max(t => t.Confidence)}");
+}
+```
+
+## Extending the Engine
+
+### Adding a New Language Adapter
+
+1. Implement `ISemanticEntrypointAnalyzer`:
+
+```csharp
+public sealed class RubySemanticAdapter : ISemanticEntrypointAnalyzer
+{
+    public IReadOnlyList<string> SupportedLanguages => new[] { "ruby" };
+    public int Priority => 100;
+
+    public ValueTask<SemanticEntrypoint> AnalyzeAsync(
+        SemanticAnalysisContext context,
+        CancellationToken cancellationToken)
+    {
+        // Detect Rails, Sinatra, Sidekiq, etc.
+    }
+}
+```
+
+2. Register in `SemanticEntrypointOrchestrator.CreateDefaultAdapters()`.
+
+### Adding a New Capability
+
+1. Add to `CapabilityClass` flags enum
+2. Update `CapabilityDetector` with detection patterns
+3. Update `ThreatVectorInferrer` if capability contributes to threats
+4. Update `DataBoundaryMapper` if capability implies I/O boundaries

+# Semantic Entrypoint Schema
+
+> Part of Sprint 0411 - Semantic Entrypoint Engine (Task 23)
+
+This document defines the schema for semantic entrypoint analysis, which enriches container scan results with application-level intent, capabilities, and threat modeling.
+
+---
+
+## Overview
+
+The Semantic Entrypoint Engine analyzes container entrypoints to infer:
+
+1. **Application Intent** - What kind of application is running (web server, worker, CLI, etc.)
+2. **Capabilities** - What system resources the application accesses (network, filesystem, database, etc.)
+3. **Attack Surface** - Potential security threat vectors based on capabilities
+4. **Data Boundaries** - Data flow boundaries with sensitivity classification
+
+This semantic layer enables more precise vulnerability prioritization by understanding which code paths are actually reachable from the entrypoint.
+
+---
+
+## Schema Definitions
+
+### SemanticEntrypoint
+
+The root type representing semantic analysis of an entrypoint.

+  capabilities: CapabilityClass;     // Bitmask of detected capabilities
+  attackSurface: ThreatVector[];

+| Go | `GoSemanticAdapter` | net/http, Gin, Echo, Cobra, gRPC |
+
+---
+
+## Configuration
+
+Semantic analysis is configured via the `Scanner:EntryTrace:Semantic` configuration section:
+
+```yaml
+Scanner:
+  EntryTrace:
+    Semantic:
+      Enabled: true
+      ThreatConfidenceThreshold: 0.3
+      MaxThreatVectors: 50
+      IncludeLowConfidenceCapabilities: false
+      EnabledLanguages: []  # Empty = all languages
+```
+
+| Option | Default | Description |
+|--------|---------|-------------|
+| `Enabled` | true | Enable semantic analysis |
+| `ThreatConfidenceThreshold` | 0.3 | Minimum confidence for threat vectors |
+| `MaxThreatVectors` | 50 | Maximum threats per entrypoint |
+| `IncludeLowConfidenceCapabilities` | false | Include low-confidence capabilities |
+| `EnabledLanguages` | [] | Languages to analyze (empty = all) |
+
+---
+
+## Determinism Guarantees
+
+All semantic analysis outputs are deterministic:
+
+1. **Capability ordering** - Flags are ordered by value (bitmask position)
+2. **Threat vector ordering** - Ordered by ThreatVectorType enum value
+3. **Data boundary ordering** - Ordered by (Type, Direction) tuple
+4. **Evidence ordering** - Alphabetically sorted within each element
+5. **JSON serialization** - Uses camelCase naming, consistent formatting
+
+This enables reliable diffing of semantic analysis results across scan runs.
+
+---
+
+## CLI Usage
+
+Semantic analysis can be enabled via the CLI `--semantic` flag:
+
+```bash
+stella scan --semantic docker.io/library/python:3.12
+```
+
+Output includes semantic summary when enabled:
+
+```
+Semantic Analysis:
+  Intent: WebServer
+  Framework: flask (v3.0.0)
+  Capabilities: NetworkListen, DatabaseSql, FileRead
+  Threat Vectors: 2 (SqlInjection, Ssrf)
+  Risk Score: 0.72
+  Confidence: High (0.85)
+```

+# Patch-Oracles QA Pattern
 
-Patch oracles are paired vulnerable/fixed binaries that prove our analyzers can see the function and call-edge deltas introduced by real CVE fixes. This file replaces earlier advisory text; use it directly when adding tests.
+Patch oracles define expected functions and edges that must be present (or absent) in generated reachability graphs. The CI pipeline uses these oracles to ensure that:
 
-## 1. Workflow (per CVE)
+1. Critical vulnerability paths are correctly identified as reachable
+2. Mitigated paths are correctly identified as unreachable
+3. Graph generation remains deterministic and complete
+
+This document covers both the **JSON-based harness** (for reachbench integration) and the **YAML-based format** (for binary patch testing).
+
+---
+
+## Part A: JSON Patch-Oracle Harness (v1)
+
+The JSON-based patch-oracle harness integrates with the reachbench fixture system for CI graph validation.
+
+### A.1 Schema Overview
+
+Patch-oracle fixtures follow the `patch-oracle/v1` schema:
+
+```json
+{
+  "schema_version": "patch-oracle/v1",
+  "id": "curl-CVE-2023-38545-socks5-heap-reachable",
+  "case_ref": "curl-CVE-2023-38545-socks5-heap",
+  "variant": "reachable",
+  "description": "Validates SOCKS5 heap overflow path is reachable",
+  "expected_functions": [...],
+  "expected_edges": [...],
+  "expected_roots": [...],
+  "forbidden_functions": [...],
+  "forbidden_edges": [...],
+  "min_confidence": 0.5,
+  "strict_mode": false
+}
+```
+
+### A.2 Expected Functions
+
+Define functions that MUST be present in the graph:
+
+```json
+{
+  "symbol_id": "sym://curl:curl.c#sink",
+  "lang": "c",
+  "kind": "function",
+  "purl_pattern": "pkg:github/curl/*",
+  "required": true,
+  "reason": "Vulnerable buffer handling function"
+}
+```
+
+### A.3 Expected Edges
+
+Define edges that MUST be present in the graph:
+
+```json
+{
+  "from": "sym://net:handler#read",
+  "to": "sym://curl:curl.c#entry",
+  "kind": "call",
+  "min_confidence": 0.8,
+  "required": true,
+  "reason": "Data flows from network to SOCKS5 handler"
+}
+```
+
+### A.4 Forbidden Elements (for unreachable variants)
+
+```json
+{
+  "forbidden_functions": [
+    {
+      "symbol_id": "sym://dangerous#sink",
+      "reason": "Should not be reachable when feature disabled"
+    }
+  ],
+  "forbidden_edges": [
+    {
+      "from": "sym://entry",
+      "to": "sym://sink",
+      "reason": "Path should be blocked by feature flag"
+    }
+  ]
+}
+```
+
+### A.5 Wildcard Patterns
+
+Symbol IDs support `*` wildcards:
+- `sym://test#func1` - exact match
+- `sym://test#*` - matches any symbol starting with `sym://test#`
+- `*` - matches anything
+
+### A.6 Directory Structure

+## Part B: YAML Binary Patch-Oracles
+
+The YAML-based format is used for paired vulnerable/fixed binary testing.
+
+### B.1 Workflow (per CVE)
 
 1) Pick a CVE with a small, clean fix (e.g., OpenSSL, zlib, BusyBox). Identify vulnerable commit `A` and fixed commit `B`.
 2) Build two stripped binaries (`vuln`, `fixed`) with identical toolchains/flags; keep a tiny harness that exercises the affected path.
