SDLC Phase-by-Phase Transformation
Planning and Design
Traditional Approach
Design happens in docs, diagrams, and meetings. The relationship between design and code is loose and often diverges over time.
With Ananke
Design decisions can be expressed as constraints that directly shape implementation. An Architectural Decision Record (ADR) isn't just documentation. Braid can extract constraints from it.
Example ADR: "We're adopting an event-driven architecture where services communicate via Kafka topics, not direct HTTP calls."
This becomes encoded constraints:
- Service-to-service HTTP calls trigger warnings
- Event schemas are validated at compile time
- Message patterns are checked for consistency
Design and implementation stay aligned because design is a constraint program.
High-Level Design Reviews
Instead of reviewing static documents, teams can review constraint programs:
- What invariants are we committing to?
- Which constraints are strict versus flexible?
- What's the intent model for this feature?
The design review outputs constraints that immediately guide implementation.
Development
We've covered individual and collaborative development above, but worth emphasizing the workflow compression:
- Traditional: design → implement → test → find violations → fix → retest
- With Ananke: design → implement under constraints → test (mostly passes) → ship
The "fix violations" loop that typically consumes 30-50% of development time shrinks dramatically because violations are prevented upfront.
Testing
Test Generation
Developers write tests manually today, often missing edge cases or failing to test the properties that actually matter.
Ananke can synthesize property-based tests from:
- Type signatures and contracts
- Intent (what should this do?)
- Telemetry (what actually happens in production?)
- Past incidents (what went wrong before?)
You get property-based tests that explore the behavior space instead of writing example-based tests. Not "assert that f(3) == 5" but "assert that this handler completes in under 200ms for all valid inputs."
Test Maintenance
Tests break for two reasons: actual regressions or refactoring. Ananke can distinguish between them because it has provenance:
- If constraints are satisfied and intent is unchanged, update tests automatically
- If constraints are violated or intent shifted, flag for human review
Test suites become more maintainable because they're generated from intent rather than manually crafted.
Code Review
Covered in detail above, but the key transformation: code review shifts from mechanical constraint checking to strategic design discussion. Review time per PR can drop 40-60% while review quality improves.
Deployment and Release
Pre-Deployment Validation
Traditional CI/CD checks syntax, tests, and maybe some static analysis. But most production issues come from violating implicit operational constraints like performance regressions, protocol incompatibilities, resource exhaustion under load, or unexpected interaction patterns.
Ananke's telemetry-informed constraints mean pre-deployment checks can:
- Predict performance impact based on observed traffic patterns
- Validate against production failure modes
- Ensure new code respects operational patterns
Progressive Rollouts
During progressive rollout, Ananke can:
- Compare telemetry against predicted behavior
- Automatically tighten constraints if anomalies appear
- Generate targeted tests based on production traffic
If a canary deployment shows unexpected behavior, Ananke can capture that as a new constraint and prevent similar issues in future deployments.
Operations and Incident Response
Faster Diagnosis
When an incident occurs, Ananke provides:
- Which constraints existed in the affected code path
- What intent guided its implementation
- What telemetry patterns were expected
- What changed recently in related systems
SREs and engineers can quickly determine: Is this a violation of known constraints (regression) or a missing constraint (new failure mode)?
Learning from Incidents
Post-incident reviews traditionally produce:
- A postmortem document (rarely read later)
- Maybe some documentation updates
- Hopefully some monitoring improvements
With Ananke, incident learnings become new constraints:
- The failure mode gets encoded as a constraint
- Future code generation avoids the pattern
- Similar code paths get flagged for review
- Tests are generated to prevent recurrence
The organization learns in a machine-actionable way.
Operational Pattern Enforcement
SRE teams develop operational wisdom: circuit breaker patterns, retry strategies, graceful degradation. Today this lives in runbooks and tribal knowledge.
With Ananke, these patterns become constraints:
- "Always wrap external calls in circuit breakers"
- "Use exponential backoff with jitter for retries"
- "Degrade gracefully when cache is unavailable"
New code automatically conforms to operational best practices.
Maintenance and Evolution
Dependency Updates
Updating dependencies today is risky. You upgrade a library and hope nothing breaks. Testing helps but can't catch all compatibility issues.
With Ananke:
- Existing constraints validate against the new dependency
- Breaking changes are detected at the constraint level
- Necessary adaptations are generated under constraints
- Migration can be partially automated while respecting system invariants
Refactoring
Large refactorings are terrifying because you might break subtle invariants. With Ananke:
- Extract constraints from the code being refactored
- Apply those constraints to the new structure
- Validate that semantic behavior is preserved
- Generate tests that verify equivalence
Refactoring becomes safer and more common, keeping codebases healthy.
Technical Debt
Technical debt accumulates when taking shortcuts that violate best practices. With Ananke:
- Debt can be explicitly flagged as "relaxed constraints for this component"
- You can see which parts of the system have tight constraints versus loose
- Paying down debt means tightening constraints and validating
- The system can prioritize debt based on risk (telemetry impact)
