Validation PipelineTiered Validation Pipeline

Information

See the finished result in a secure preview before you merge, not only a passing check, with Production-Grade.

Foundry's validation is designed to be highly deterministic and cheap, falling back to AI only when necessary.1. Deterministic Pre-ValidationFast, local, non-AI checks.

Rules: Strict rules including catastrophic regex guards, file/byte caps (MAX_FILES_SCANNED: 2000), semver matching, and safe extension filtering.

Outcome: If HIGH confidence, the pipeline stops here and marks the task as complete.

2. Interrogation PhaseIf deterministic checks yield MEDIUM or UNCERTAIN confidence, a cached helper AI session is invoked. It generates shell commands (grep, cat) to gather actual evidence from the disk.3. AST ValidationDeep structural analysis checking for:

Classes, Functions, Exports, Imports, Interfaces, Decorators.

4. Result CachingTo improve performance, validation results are cached in Redis.

Key: Hash of Project ID + Criterion + File Content (SHA-256).

If file content hasn't changed, the previous validation result is reused instantly.

Confidence Levels

Level

Action

HIGH

Explicit evidence found. Done.

MEDIUM

Evidence inferred. Invoke helper.

UNCERTAIN

Evidence weak. Trigger Interrogation.

LOW

Interrogation failed. Trigger Retry.
