Signum — Evidence-Driven Development Pipeline

Name: signum
Author: heurema

Run a CONTRACT → EXECUTE → AUDIT → PACK pipeline for any implementation task.

When to Use

User asks to "implement X" and you want verifiable correctness
Task requires multi-model code review
Changes need proof artifacts for CI/CD gates
Risk is medium-high and ad hoc coding is insufficient

Pipeline

CONTRACT — Turn the request into a verifiable contract with acceptance criteria
EXECUTE — Implement against the contract, not a vague prompt
AUDIT — Deterministic checks (lint, test, scope) + optional multi-model review
PACK — Package into a proofpack artifact with verdict (AUTO_OK / HUMAN_REVIEW / AUTO_BLOCK)

Core Rules

Do not start implementation before a contract exists
If the contract is vague, stop and improve it
Check against deterministic criteria, not just model opinion
Keep active run/pipeline artifacts under .signum/contracts/<contractId>/
Treat root .signum/ as the registry/state/archive/compatibility namespace, not the canonical per-run artifact root
If reduced audit coverage on medium/high-risk task → HUMAN_REVIEW, not AUTO_OK
