<!--
  This is the upgrade progress tracker generated during plan execution.
  Each step from plan.md should be tracked here with status, changes, verification results, and TODOs.

  ## EXECUTION RULES

  !!! DON'T REMOVE THIS COMMENT BLOCK BEFORE UPGRADE IS COMPLETE AS IT CONTAINS IMPORTANT INSTRUCTIONS.

  ### Success Criteria
  - **Goal**: All user-specified target versions met
  - **Compilation**: Both main source code AND test code compile = `mvn clean test-compile` succeeds
  - **Test**: 100% test pass rate = `mvn clean test` succeeds (or ≥ baseline with documented pre-existing flaky tests), but ONLY in Final Validation step. **Skip if user set "Run tests before and after the upgrade: false" in plan.md Options.**

  ### Strategy
  - **Uninterrupted run**: Complete execution without pausing for user input
  - **NO premature termination**: Token limits, time constraints, or complexity are NEVER valid reasons to skip fixing.
  - **Automation tools**: Use OpenRewrite etc. for efficiency; always verify output

  ### Verification Expectations
  - **Steps 1-N (Setup/Upgrade)**: Focus on COMPILATION SUCCESS (both main and test code).
    - On compilation success: Commit and proceed (even if tests fail - document count)
    - On compilation error: Fix IMMEDIATELY and re-verify until both main and test code compile
    - **NO deferred fixes** (for compilation): "Fix post-merge", "TODO later", "can be addressed separately" are NOT acceptable. Fix NOW or document as genuine unfixable limitation.
  - **Final Validation Step**: Achieve COMPILATION SUCCESS + 100% TEST PASS (if tests enabled in plan.md Options).
    - On test failure: Enter iterative test & fix loop until 100% pass or rollback to last-good-commit after exhaustive fix attempts
    - **NO deferring test fixes** - this is the final gate
    - **NO categorical dismissals**: "Test-specific issues", "doesn't affect production", "sample/demo code" are NOT valid reasons to skip. ALL tests must pass.
    - **NO "close enough" acceptance**: 95% is NOT 100%. Every failing test requires a fix attempt with documented root cause.
    - **NO blame-shifting**: "Known framework issue", "migration behavior change" require YOU to implement the fix or workaround.

  ### Review Code Changes (MANDATORY for each step)
  After completing changes in each step, review code changes BEFORE verification to ensure:

  1. **Sufficiency**: All changes required for the upgrade goal are present — no missing modifications that would leave the upgrade incomplete.
     - All dependencies/plugins listed in the plan for this step are updated
     - All required code changes (API migrations, import updates, config changes) are made
     - All compilation and compatibility issues introduced by the upgrade are addressed
  2. **Necessity**: All changes are strictly necessary for the upgrade — no unnecessary modifications, refactoring, or "improvements" beyond what's required. This includes:
     - **Functional Behavior Consistency**: Original code behavior and functionality are maintained:
       - Business logic unchanged
       - API contracts preserved (inputs, outputs, error handling)
       - Expected outputs and side effects maintained
     - **Security Controls Preservation** (critical subset of behavior):
       - **Authentication**: Login mechanisms, session management, token validation, MFA configurations
       - **Authorization**: Role-based access control, permission checks, access policies, security annotations (@PreAuthorize, @Secured, etc.)
       - **Password handling**: Password encoding/hashing algorithms, password policies, credential storage
       - **Security configurations**: CORS policies, CSRF protection, security headers, SSL/TLS settings, OAuth/OIDC configurations
       - **Audit logging**: Security event logging, access logging

  **Review Code Changes Actions**:
  - Review each changed file for missing upgrade changes, unintended behavior or security modifications
  - If behavior must change due to framework requirements, document the change, the reason, and confirm equivalent functionality/protection is maintained
  - Add missing changes that are required for the upgrade step to be complete
  - Revert unnecessary changes that don't affect behavior or security controls
  - Document review results in progress.md and commit message

  ### Commit Message Format
  - First line: `Step <x>: <title> - Compile: <result> | Tests: <pass>/<total> passed`
  - Body: Changes summary + concise known issues/limitations (≤5 lines)
  - **When `GIT_AVAILABLE=false`**: Skip commits entirely. Record `N/A - not version-controlled` in the **Commit** field.

  ### Efficiency (IMPORTANT)
  - **Targeted reads**: Use `grep` over full file reads; read specific sections, not entire files. Template files are large - only read the section you need.
  - **Quiet commands**: Use `-q`, `--quiet` for build/test commands when appropriate
  - **Progressive writes**: Update progress.md incrementally after each step, not at end

## Step Details

<!--
  For each step in plan.md, track progress using this bullet list format:

  - **Step N: <Step Title>**
    - **Status**: <status emoji>
      - 🔘 Not Started - Step has not been started yet
      - ⏳ In Progress - Currently working on this step
      - ✅ Completed - Step completed successfully
      - ❗ Failed - Step failed after exhaustive attempts
    - **Changes Made**: (≤5 bullets, keep each ≤20 words)
      - Focus on what changed, not how
    - **Review Code Changes**:
      - Sufficiency: ✅ All required changes present / ⚠️ <list missing changes added, short and concise>
      - Necessity: ✅ All changes necessary / ⚠️ <list unnecessary changes reverted, short and concise>
        - Functional Behavior: ✅ Preserved / ⚠️ <list unavoidable changes with justification, short and concise>
        - Security Controls: ✅ Preserved / ⚠️ <list unavoidable changes with justification and equivalent protection, short and concise>
    - **Verification**:
      - Command: <actual command executed>
      - JDK: <JDK path used>
      - Build tool: <Path of build tool used>
      - Result: <SUCCESS/FAILURE with details>
      - Notes: <any skipped checks, excluded modules, known issues>
    - **Deferred Work**: List any deferred work, temporary workarounds (or "None")
    - **Commit**: <commit hash> - <commit message first line>  <!-- use "N/A - not version-controlled" when GIT_AVAILABLE=false -->

## Notes

<!--
  Additional context, observations, or lessons learned during execution.
  Use this section for:
  - Unexpected challenges encountered
  - Deviation from original plan
  - Performance observations
  - Recommendations for future upgrades

  SAMPLE:
  - OpenRewrite's jakarta migration recipe saved ~4 hours of manual work
  - Hibernate 6 query syntax changes were more extensive than anticipated
  - JUnit 5 migration was straightforward thanks to Spring Boot 2.7.x compatibility layer
