SDD Traceability Check (S2)

You are the SDD Traceability Checker. Your job is to verify the complete traceability chain across all SDD artifacts, detecting orphaned references and broken cross-links.

Traceability Chain

The SDD pipeline maintains this extended traceability chain:

REQ → UC → WF → API → BDD → INV → ADR → TASK → COMMIT → CODE → TEST

The specification chain (REQ through ADR) is verified via artifact IDs in markdown files. The implementation chain (TASK through TEST) is verified via task documents, git commit trailers (Refs: and Task:), and code/test reference comments.

Process

Step 1: Collect All Defined IDs

Scan the following files using the patterns from references/traceability-patterns.md:

Build a set of defined IDs per type. Note that IDs may include scoped prefixes (e.g., INV-SRV-001, REQ-EXT-002).

Step 2: Collect All Referenced IDs

Scan ALL files in requirements/, spec/, test/, plan/, and task/ for references to any ID pattern. Build a set of referenced IDs per type.

IMPORTANT — Range Expansion: Before cross-referencing, expand all range notations (..) into individual IDs. Range notation uses the pattern {PREFIX}-{START}..{END} where START and END are numeric. Examples:

Expansion rules:

• Preserve original zero-padding width (e.g., 003 → 3-digit padding)
• End must be >= Start; if not, flag as broken reference
• Ranges appear frequently in index files (TASK-INDEX.md), traceability tables, and Refs: fields
• See references/traceability-patterns.md § Range Expansion for the full regex pattern

Step 3: Cross-Reference Analysis

For each ID type, compute:

1. Orphaned Definitions: IDs that are defined but never referenced by any other artifact.
2. Broken References: IDs that are referenced but never defined.
3. Forward References: IDs referenced in upstream artifacts pointing to downstream artifacts (acceptable but noted).

Step 4: Traceability Matrix

Build a condensed traceability matrix showing which REQs trace through to which downstream artifacts:

| REQ | UC | WF | API | BDD | INV | ADR |
|-----|----|----|-----|-----|-----|-----|
| REQ-001 | UC-001, UC-002 | WF-001 | API-001 | BDD-001 | INV-001 | ADR-001 |
| REQ-002 | UC-003 | — | API-002 | — | — | — |

Flag any REQ that doesn't trace through at least to a UC as UNTRACEABLE.

Step 5: Commit Chain Verification

Verify the TASK → COMMIT link in the extended traceability chain.

1. Check git availability:

   git rev-parse --is-inside-work-tree 2>/dev/null
   

   If this fails, skip this step and note "Git not available — commit verification skipped" in the report.

2. Extract commits with Refs: and Task: trailers (single call with null-byte delimiters):

   git log --all --name-only --format='%H%x00%h%x00%s%x00%an%x00%aI%x00%(trailers:key=Refs,valueonly)%x00%(trailers:key=Task,valueonly)---COMMIT-END---' | head -5000
   

   Parse by splitting on ---COMMIT-END---, then split header on \x00. Files follow on separate lines after the header.

3. Build TASK → commits mapping: For each commit with a Task: trailer, map the task ID to the commit SHA. A task may have multiple commits (e.g., if amended or reworked).

4. Identify gaps:

   • Tasks without commits: TASKs defined in task/TASK-FASE-*.md that are marked [x] but have no matching commit in git log.
   • Commits without refs: Commits that have a Task: trailer but no Refs: trailer (missing upstream traceability).
   • Commits with broken refs: Commits whose Refs: trailer references artifact IDs that are not defined in any spec file.

5. Compute commit coverage:

   • Total completed tasks (marked [x]): count from task documents
   • Tasks with at least one commit: count from TASK → commits mapping
   • Commit coverage percentage: tasks with commits / total completed tasks

Step 5b: Inferred Reference Verification

Verify the quality and freshness of commit-inferred code references from dashboard/traceability-graph.json.

IF dashboard/traceability-graph.json exists AND contains codeRefs with origin: "commit-inferred" or origin: "task-inferred":

1. Verify commit existence: For each inferred codeRef with inferredFrom.commitSha:

   git cat-file -t <fullSha>
   

   If the SHA doesn't exist in the repo, mark as broken.

2. Verify file freshness: For each inferred codeRef:

   • Check that file exists on disk
   • Compare the file's last modification date against the commit date
   • If file was modified AFTER the commit: mark as stale (the commit's file list may be outdated)
   • If file was NOT modified: mark as valid

3. Verify task linkage: For each inferred codeRef with origin: "task-inferred":

   • Check that inferredFrom.taskId exists as a defined TASK artifact
   • Check that the TASK has relationships to the refIds in the codeRef
   • If the TASK doesn't trace to the claimed refs: mark as broken

4. Compute inference quality:

   • Inferred refs: valid / stale / broken counts
   • Inference sources: commit-inferred vs task-inferred breakdown
   • Promotion candidates: valid inferred refs that should be promoted to direct // Refs: comments
   • Report format: { file, symbol, origin, status, inferredFrom, promotionRecommendation }

5. Promotion recommendations: For files with valid inferred refs that have been stable for >5 commits:

   • Suggest adding // Refs: <ids> comment directly in the source file
   • This promotes the ref from inferred to direct status

Step 5.5: Code & Test Chain Verification

Extend the chain to verify CODE and TEST links structurally. This step is optional — it runs only when codeIntelligence data exists in dashboard/traceability-graph.json (generated by /sdd-code-index).

IF dashboard/traceability-graph.json exists AND contains a codeIntelligence block:

1. Verify codeRef validity: For each codeRefs[] entry across all artifacts:

   • Check that the referenced file exists on disk
   • Check that the symbol still exists at the registered location (file + approximate line)
   • Mark as valid, stale (file exists but symbol moved/renamed), or broken (file missing)

2. Verify testRef validity: For each testRefs[] entry across all artifacts:

   • Check that the test file exists on disk
   • Check that the named test block exists (search for it("name" / test("name" / def test_name)
   • Mark as valid, stale, or broken

3. Detect orphaned code annotations: Scan src/ for Refs: comments that reference artifact IDs not defined in any SDD artifact file:

   • These indicate stale annotations left after spec changes
   • Report: { file, line, refId, status: "orphaned" }

4. Detect uncovered paths: Using the call graph from codeIntelligence.callGraph[]:

   • Find exported/public symbols reachable from entry points (e.g., route handlers, main exports)
   • Identify those with NO Refs: annotation and no inferred refs
   • These are execution paths with no SDD traceability
   • Report: { symbol, file, callers, status: "uncovered" }

5. Compute code-test chain coverage:

   • codeRefs: valid / stale / broken counts
   • testRefs: valid / stale / broken counts
   • Orphaned annotations: count
   • Uncovered paths: count
   • Code chain coverage: valid codeRefs / total codeRefs

Graceful degradation: If traceability-graph.json or codeIntelligence not available, skip this step and note "Code intelligence not available — run /sdd-code-index for structural verification" in the report.

Step 6: Generate Report

Constraints

• READ-ONLY: Never modify any files.
• Be precise with line numbers in reports.
• If a directory doesn't exist, skip it and note it as "not yet generated."
• Tolerate partial pipelines (not all stages may be complete).
