Executive Summary​

This document provides a comprehensive root cause analysis of why Task numbers are not correctly mapping to the version TASK component. The analysis identifies 4 primary root causes and 6 contributing factors, leading to 8 specific documentation and process gaps that must be addressed to prevent recurrence.

1. Problem Statement​

Symptom: Task numbers are not correctly mapping to version TASK component. All Tasks within a Story are using TASK=1, with BUILD incrementing across Tasks (2, 3, 4, 5, 6...).

Expected Behavior:

  • Task 1 → v0.4.1.1+1 (Epic 4, Story 1, Task 1, Build 1)
  • Task 2 → v0.4.1.2+1 (Epic 4, Story 1, Task 2, Build 1)
  • Task 3 → v0.4.1.3+1 (Epic 4, Story 1, Task 3, Build 1)

Actual Behavior:

  • Task 1 → v0.4.1.1+2 (Epic 4, Story 1, Task 1, Build 2) ❌
  • Task 2 → v0.4.1.1+3 (Epic 4, Story 1, Task 1, Build 3) ❌
  • Task 3 → v0.4.1.1+4 (Epic 4, Story 1, Task 1, Build 4) ❌

Impact:

  • Version numbers don't reflect actual Task progression
  • Cannot distinguish between Tasks using version numbers alone
  • Violates versioning schema rules
  • Breaks forensic traceability (version → Task mapping is incorrect)

2. Root Cause Analysis​

2.1 Primary Root Cause: Missing Task Transition Detection in RW Step 2​

Root Cause: Release Workflow Step 2 (Bump Version) does not explicitly detect Task transitions and update VERSION_TASK accordingly.

Evidence:

  • RW Step 2 documentation says: "Determine if this is a task transition (would reset BUILD to 1)"
  • But it does NOT say: "If task transition detected, UPDATE VERSION_TASK to match new Task number"
  • RW Step 2 only increments BUILD, it doesn't check if we're on a new Task

Location: packages/frameworks/workflow mgt/docs/documentation/Developer_Docs/vwmp/release-workflow-agent-execution.md (Step 2)

Why It Happened:

  • Step 2 was designed to handle BUILD increments within the same Task
  • Task transitions were assumed to be handled elsewhere (intake process)
  • No explicit instruction to detect and handle Task transitions in Step 2

2.2 Secondary Root Cause: No Validation of TASK Component​

Root Cause: No validation checks that VERSION_TASK matches the active Task number before or during RW execution.

Evidence:

  • validate_branch_context.py checks Epic/Story alignment but NOT Task alignment
  • No validation in RW Step 2 to verify VERSION_TASK matches active Task
  • No pre-commit hooks to enforce Task/version alignment

Location:

  • packages/frameworks/workflow mgt/scripts/validation/validate_branch_context.py
  • RW Step 2 validation section

Why It Happened:

  • Validation was focused on Epic/Story alignment (branch context)
  • Task-level validation was assumed to be handled by manual process
  • No explicit requirement for Task/version validation

2.3 Tertiary Root Cause: Intake Process Doesn't Update version.py​

Root Cause: FR/BR intake process assigns version numbers but doesn't explicitly update version.py with the new Task number.

Evidence:

  • Intake guide says: "Assign version number: RC.EPIC.STORY.TASK+BUILD"
  • But it doesn't say: "Update version.py with VERSION_TASK = <new_task_number>"
  • Intake process assumes version.py will be updated later (by RW or manually)

Location: packages/frameworks/kanban/FR_BR_INTAKE_GUIDE.md (Step 6)

Why It Happened:

  • Intake process focuses on Kanban structure (Epic/Story/Task creation)
  • Version assignment is documented but not enforced
  • Assumption that RW will handle version file updates

2.4 Quaternary Root Cause: Documentation Ambiguity on Task Transitions​

Root Cause: Documentation mentions Task transitions but doesn't provide clear, actionable steps for agents to follow.

Evidence:

  • Kanban governance policy says: "Task transitions use --task N parameter"
  • But RW agent execution guide doesn't mention --task parameter
  • No clear distinction between "same Task, new BUILD" vs "new Task, reset BUILD"

Location:

  • packages/frameworks/kanban/policies/kanban-governance-policy.md
  • packages/frameworks/workflow mgt/docs/documentation/Developer_Docs/vwmp/release-workflow-agent-execution.md

Why It Happened:

  • Documentation evolved from different sources (Kanban policy vs RW guide)
  • --task parameter concept from framework but not implemented in agent guide
  • No single source of truth for Task transition handling

3. Contributing Factors​

3.1 Manual Process Dependency​

Factor: VERSION_TASK updates require manual intervention, which is error-prone.

Impact: Agents must remember to manually update VERSION_TASK when starting a new Task, but this step is easily forgotten.

Evidence: All completed Tasks show TASK=1, indicating manual updates were not consistently performed.

3.2 BUILD Increment Masks the Issue​

Factor: RW automatically increments BUILD, which creates valid-looking version numbers even when TASK is incorrect.

Impact: The issue is not immediately obvious because version numbers still increment (BUILD), making it appear that the system is working correctly.

Evidence: Versions like v0.4.1.1+2, v0.4.1.1+3 look valid but don't reflect Task progression.

3.3 No Clear "Start New Task" Workflow​

Factor: There's no explicit workflow step for "starting a new Task" that triggers VERSION_TASK update.

Impact: Agents don't know when or how to update VERSION_TASK when moving to a new Task.

Evidence: No documentation explicitly says: "When starting Task 2, update VERSION_TASK = 2 in version.py"

3.4 Version File Update Timing Ambiguity​

Factor: Unclear when version.py should be updated: at Task creation, at RW start, or during RW execution.

Impact: Different agents may update version.py at different times, leading to inconsistencies.

Evidence: Some Tasks may have had version.py updated at creation, others during RW, others not at all.

3.5 Lack of Examples Showing Task Transitions​

Factor: Documentation examples show BUILD increments but not Task transitions.

Impact: Agents don't have clear examples of how Task transitions should work.

Evidence: RW Step 2 examples show: 0.2.1.1+2 → 0.2.1.1+3 (same Task), but not: 0.2.1.1+1 → 0.2.1.2+1 (new Task)

3.6 No Pre-RW Validation Checklist​

Factor: No checklist or validation step before RW execution to verify VERSION_TASK matches active Task.

Impact: Issues are only discovered after RW completes, requiring corrections.

Evidence: Validation happens in Step 8 (after version bump), not in Step 1 (before starting).

4. Documentation and Process Gaps​

4.1 RW Step 2: Missing Task Transition Logic​

Gap: Step 2 doesn't explicitly detect Task transitions and update VERSION_TASK.

Required Fix:

  • Add explicit check: "Is this a new Task compared to previous release?"
  • Add explicit action: "If new Task, update VERSION_TASK to match new Task number"
  • Add explicit action: "If new Task, reset VERSION_BUILD to 1"

Location: packages/frameworks/workflow mgt/docs/documentation/Developer_Docs/vwmp/release-workflow-agent-execution.md (Step 2)

4.2 RW Step 1: Missing Task Validation​

Gap: Step 1 (Branch Safety Check) doesn't validate that VERSION_TASK matches the active Task.

Required Fix:

  • Add validation: "Verify VERSION_TASK matches active Task number from Story document"
  • Add check: "If mismatch, STOP workflow and alert user"

Location: packages/frameworks/workflow mgt/docs/documentation/Developer_Docs/vwmp/release-workflow-agent-execution.md (Step 1)

4.3 Intake Guide: Missing version.py Update Step​

Gap: Intake guide doesn't explicitly require updating version.py when creating a new Task.

Required Fix:

  • Add step: "Update version.py with VERSION_TASK = <new_task_number>"
  • Add validation: "Verify VERSION_TASK matches Task number"

Location: packages/frameworks/kanban/FR_BR_INTAKE_GUIDE.md (Step 6)

4.4 Validation Script: Missing Task Alignment Check​

Gap: validate_branch_context.py doesn't check Task/version alignment.

Required Fix:

  • Add check: "Verify VERSION_TASK matches active Task number"
  • Add check: "Verify Task exists in Story document"

Location: packages/frameworks/workflow mgt/scripts/validation/validate_branch_context.py

4.5 Versioning Policy: Missing Task Transition Rules​

Gap: Versioning policy doesn't explicitly state how Task transitions should be handled.

Required Fix:

  • Add section: "Task Transitions"
  • Add rule: "When moving to a new Task, VERSION_TASK must be updated and VERSION_BUILD must reset to 1"
  • Add examples showing Task transitions

Location: docs/architecture/standards-and-adrs/dev-kit-versioning-policy.md

4.6 Kanban Governance: Missing version.py Update Requirement​

Gap: Kanban governance policy mentions --task parameter but doesn't explain how agents should handle Task transitions.

Required Fix:

  • Add section: "Version File Updates During Task Transitions"
  • Add requirement: "When starting a new Task, version.py must be updated with new VERSION_TASK"
  • Add requirement: "RW Step 2 must detect Task transitions and update VERSION_TASK"

Location: packages/frameworks/kanban/policies/kanban-governance-policy.md

4.7 Agent Guide: Missing Task Transition Examples​

Gap: Agent execution guide doesn't show examples of Task transitions.

Required Fix:

  • Add example: "Moving from Task 1 to Task 2"
  • Add example: "RW Step 2 handling Task transition"
  • Add example: "Version file update during Task transition"

Location: packages/frameworks/workflow mgt/docs/documentation/Developer_Docs/vwmp/release-workflow-agent-execution.md

4.8 Intake Agent Guide: Missing version.py Update​

Gap: Intake agent guide doesn't mention updating version.py when creating Tasks.

Required Fix:

  • Add step: "Update version.py with new Task number"
  • Add validation: "Verify VERSION_TASK matches Task number"

Location: packages/frameworks/kanban/FR_BR_INTAKE_AGENT_GUIDE.md

5. Why This Wasn't Caught Earlier​

5.1 No Automated Validation​

Reason: No automated checks to verify Task/version alignment.

Impact: Issues only discovered through manual review (validation report).

5.2 Documentation Assumed Manual Process​

Reason: Documentation assumed agents would manually update VERSION_TASK when needed.

Impact: Manual process is error-prone and easily forgotten.

5.3 BUILD Increments Masked the Issue​

Reason: BUILD increments made version numbers look valid even when TASK was incorrect.

Impact: Issue not immediately obvious during RW execution.

5.4 No Examples of Correct Task Transitions​

Reason: Documentation examples only showed BUILD increments, not Task transitions.

Impact: Agents didn't have clear guidance on how Task transitions should work.

6. Prevention Strategy​

6.1 Immediate Fixes​

  1. Update RW Step 2: Add explicit Task transition detection and VERSION_TASK update logic
  2. Update RW Step 1: Add Task/version validation check
  3. Update Validation Script: Add Task alignment validation
  4. Update Intake Guides: Add explicit version.py update step

6.2 Process Improvements​

  1. Add Pre-RW Checklist: Verify VERSION_TASK matches active Task before starting RW
  2. Add Task Transition Examples: Show correct Task transition handling in documentation
  3. Add Validation Hooks: Pre-commit hooks to enforce Task/version alignment

6.3 Long-Term Solutions​

  1. Automate Task Detection: RW Step 2 automatically detects Task transitions
  2. Automate version.py Updates: RW Step 2 automatically updates VERSION_TASK when Task transition detected
  3. Add Comprehensive Validation: Multi-layer validation (pre-RW, during RW, post-RW)

7. Conclusion​

The root cause of Task → version TASK component mapping failure is a systemic documentation and process gap across multiple files:

  1. RW Step 2 doesn't detect Task transitions and update VERSION_TASK
  2. RW Step 1 doesn't validate Task/version alignment
  3. Intake guides don't require version.py updates
  4. Validation scripts don't check Task alignment
  5. Versioning policy doesn't explicitly state Task transition rules
  6. Kanban governance doesn't explain Task transition handling
  7. Agent guides don't show Task transition examples
  8. No validation at any layer to catch the issue

All 8 gaps must be addressed to prevent recurrence. The fixes are documented in the updated policy and process documents.
