…ge overview and install instructions The demo corpus flood-* documents all had identical embeddings, which compressed the MAD to near-zero and caused kb-2 (a clean document) to be flagged as a norm outlier (robust z = -4.0). Fixed by giving each flood-* document a slightly different embedding while keeping the texts identical — the duplication detector still catches the flooding attack, and clean kb-* documents now pass the embedding anomaly detector without false positives. Also added a plain-language "What is this?" section and comprehensive install scripts (install.sh + install.ps1) via the enrich pipeline.
- core.load_jsonl: guard IsADirectoryError before open(); improve non-dict error message with actual type name - core.scan_corpus: validate docs is a list (TypeError) and dup_threshold is a float in (0.0, 1.0] (ValueError) before running any detectors - cli.main: validate --dup-threshold range (exit 2 with message); catch IsADirectoryError, PermissionError, OSError from load_jsonl and wrap scan_corpus errors — no raw traceback on bad input; fix getattr guard so no-command path is robust - integrations/webhook.py: validate URL scheme (http/https only); validate --timeout > 0; reject empty or non-JSON stdin; validate header format (Key: Value); distinguish HTTPError/URLError/OSError - tests/test_hardening.py: 24 new tests covering missing file (exit 2), directory path (exit 2), out-of-range threshold (exit 2), malformed JSONL (exit 2), empty corpus, non-list docs, None/missing text fields, non-numeric embeddings, and all-zero severity counts

This PR applies a few small, mechanically-verified hardening fixes found by an automated audit of the Cognis suite:
pip installline(s) in README (package is not on PyPI; use the working git+https install)Each change is deterministic; all touched Python files were confirmed to still compile (
