"""Chaos mode — EAM-inspired zero-config auto-ingest.

arXiv insight (EAM / HeatherDB): the UX is "dump text in, intelligence
emerges." EAM conflates storage with inference — we reject that as
a black box. But the UX itself is the right default: most users
shouldn't have to tune patterns, configure idiolect dictionaries,
or wire bridges. They should just dump text in.

This module provides a one-call auto-ingest path:

    chaos_ingest(mem, list_of_texts, user_id="default")

That runs the FULL pipeline with sensible defaults:
    - per-user idiolect normalizer (built-in text-speak escape hatch)
    - DisSim recursive simplification (splits compound sentences so
      the pattern extractor sees one fact per clause)
    - pattern extractor (μ=0, deterministic)
    - lifecycle / contradiction / palace encoding / edges

The user can LATER opt into deterministic mode (call mem.add()
directly) when they want explicit control over the pipeline. This
matches EAM's "magic" UX without inheriting EAM's opacity — every
fact has full provenance, the Memory Git ancestry is preserved,
and the audit log records which sub-module extracted what.

Why the name: "chaos mode" because raw chaotic text → structured
facts, no user configuration required. Let EAM sell the magic;
Context-M keeps the receipts.
