ql-intent-check — intent-drift audit

Purpose

Long pipelines (brainstorm → spec → plan → execute → review) paraphrase. Each stage re-reads an upstream artifact and rewrites it in its own format. Over 5 stages and 20+ agent invocations, the user's original intent can drift significantly — ACs silently reinterpreted, non-goals forgotten, constraints softened.

Academic backing:

• Semantic Consensus Framework (SCF, arXiv:2604.16339): formally names "Semantic Intent Divergence" as the root cause of multi-agent SWE failures. Prescribes per-agent Semantic Intent Graph + Drift Monitor.
• Agent Drift (arXiv:2601.04170): introduces Agent Stability Index (ASI) and shows all models drift under pressure.
• Goal Drift in LM Agents (arXiv:2505.02709): Claude 3.5 Sonnet holds goals for 100K tokens but drifts under competing objectives.

ql-intent-check operationalizes a lean version of SCF's Drift Monitor for quantum-loop's pipeline.

Immutable intent snapshot

The first time /ql-brainstorm runs, it MUST store the user's verbatim first-message text at quantum.json.userIntent:
