Verification and quality gates

FalconSmith does not consider a library complete until all verification steps have passed.

Verification is explicit, deterministic, and enforced automatically. There are no partial successes and no silent fallbacks.

Verification philosophy

FalconSmith focuses on producing correct systems, not just build artifacts.

Correctness in this context means:

• Structural integrity
• Consistency between Python and native layers
• Accurate, generated documentation
• Reproducible behavior across environments

Verification is therefore a mandatory phase of the delivery process.

Verification invariants

• Verification cannot be bypassed
• All checks must pass for delivery to complete
• Failures abort the process immediately
• No fallback or degraded success states exist

A FalconSmith delivery is either fully verified or not produced at all.

What is verified

1. Structural integrity

• Expected directories and files exist
• Engine and project boundaries are preserved
• No unexpected artifacts are introduced

2. Static source analysis

• Public APIs are enumerated
• Module visibility is validated
• Structure and imports are reconciled

Verification does not depend on runtime execution side effects or implicit imports. All checks are performed against explicit structure, manifests, and compiled artifacts.

Analysis is performed without relying on runtime imports or side effects.

3. Native parity validation

• Native modules are correctly exposed to Python
• Documentation is present and aligned with exposed APIs
• Python and native interfaces agree
• Artifacts match declared native sources

4. Inventory and contract validation

FalconSmith maintains an internal inventory describing modules, bindings, interfaces, and engine components.

• Observed project state must match the inventory
• Missing or extraneous components are detected

Verification is performed against deterministic inventory data and exposure manifests, ensuring that structure, native bindings, and documentation remain fully aligned.

5. Test execution

• FalconSmith engine tests
• Client library tests
• Native integration tests (when applicable)

Test failures abort the process.

6. Runtime integrity

• Every embedded component - interpreters, uv, toolchain drivers, wheels - is sha256-pinned in the approved, git-tracked manifest
• Delivered runtime bytes are re-hashed against the manifest before any environment is built on them (verify-on-consume)
• Every environment activation re-checks the live system against the approved fingerprint (forge reconcile, read-only)
• Every reconciliation is retained in an append-only audit history

A tampered or corrupted component does not fail silently - it is named, with the expected and observed hashes, before anything is built on it.

Verification output

Verification results are emitted explicitly in terminal output.

• All verification checks passed
• System state matches validated structure and inventory
• The library is safe to extend within enforced constraints

This output forms part of the delivery record and can be archived or audited independently.

What verification guarantees

When verification succeeds, FalconSmith guarantees that:

• The project structure is intentional and coherent
• Python and native layers are aligned
• Documentation reflects the exposed API
• Tests validate both engine and client behavior

Verification does not guarantee scientific correctness. It guarantees correctness of the engineering system.

What verification is not

• Not advisory or best-effort
• Not runtime monitoring
• Not a substitute for scientific validation
• Not an inference of developer intent

Role in long-lived projects

Most failures in long-running scientific systems occur during maintenance, not initial development.

Verification exists to reduce the risk of:

• Structural drift
• Broken native interfaces
• Undocumented or partially exposed APIs
• Loss of confidence over time

The same checks can be re-run as the project evolves, reasserting the same guarantees enforced at generation time.

Summary

FalconSmith treats verification as a core engineering responsibility.

By enforcing explicit quality gates, the system ensures that delivered libraries remain structurally sound, inspectable, and maintainable over time.
