RISK PATTERNS (actionable only):
- [Action Required] 3 patterns:
* when CI builds and code changes happen together, novelty of file pairings and build time tend to move together.
* when deployments and code changes happen together, novelty of file pairings tends to move together.
* when CI builds and code changes happen together, novelty of file pairings tends to move together.
Impact: Files that don't normally change together are being modified in the same commits. This indicates novel, untested interactions that may introduce bugs. Escalated from Needs Attention — multiple correlated patterns converge on the same signal families.
Action: Investigate which files are being combined unexpectedly. Prioritize testing these changes.
- [Action Required] when deployments and code changes happen together, change focus and release frequency tend to move together.
Impact: Time between releases is increasing. This could indicate a bottleneck in the release process or accumulating risk in larger releases. Escalated from Worth Monitoring — multiple correlated patterns converge on the same signal families.
Action: Check if process changes or staffing issues are delaying releases.
- [Action Required] when CI builds and code changes happen together, change focus and build time tend to move together.
(3 independent confirmations)
Impact: Builds are taking longer. Slower CI feedback loops reduce developer productivity and delay catching issues. Escalated from Worth Monitoring — multiple correlated patterns converge on the same signal families.
Action: Profile the build pipeline to identify bottlenecks. Check for newly added expensive tests or build steps.
- [Action Required] 4 patterns:
* when deployments and code changes happen together, code spread and release frequency tend to move together.
* when CI builds and code changes happen together, code spread and build time tend to move together.
* when deployments and code changes happen together, code spread tends to move together.
* when CI builds and code changes happen together, code spread tends to move together.
Impact: Changes are spreading across unrelated parts of the codebase. This makes reviews harder and increases the chance of unexpected side effects. Escalated from Worth Monitoring — multiple correlated patterns converge on the same signal families.
Action: Review recent PRs for scope creep. Consider breaking large changes into focused commits.

Impact: Commits are touching more files than usual, increasing review burden and risk of regressions. Escalated from Worth Monitoring — multiple correlated patterns converge on the same signal families.
Action: Monitor PR sizes. If this persists, investigate whether large refactors need better decomposition.
- [Action Required] when CI builds and code changes happen together, change focus tends to move in opposite directions.
Impact: Changes span files that don't normally change together, suggesting cross-cutting concerns that may be harder to test. Escalated from Worth Monitoring — multiple correlated patterns converge on the same signal families.
Action: Review whether these cross-cutting changes have adequate test coverage.
- [Worth Monitoring] when dependency changes and deployments happen together, dependency count and release frequency tend to move together.
(2 independent confirmations)
Impact: The dependency count is growing, expanding the supply-chain attack surface and potential for version conflicts.
Action: Audit new dependencies for necessity, maintenance status, and known vulnerabilities.

TASKS:
1. ROOT CAUSE: For each deviation, identify the commit(s) that caused it.
Focus on [Action Required] and [Needs Attention] items first.
2. FIXES: Provide concrete fixes with file paths and code changes.
Goal: bring metrics back toward baseline without disrupting velocity.
3. PRIORITY: Rank fixes by urgency (immediate vs. next sprint).
4. AFTER FIXING: Run `evo analyze . --verify` to confirm deviations decreased.
If a change was intentional, accept it: `evo accept . <N>`.
5. FINDING SUMMARIES: At the end, include a section like this:
