v0.1.9 — Coverage gate (80%) + safer truncation

v0.1.9

Added

• CI now enforces a minimum 80% test coverage (--cov-fail-under=80).
• New unit test suite tests/unit/test_coverage_features.py covering:
  • Secrets & PII redaction
  • Chunking (line + Python AST spans)
  • RAG lexical retrieval
  • Tracing (JSONL)
  • Snapshots (manifest + rendered output)
  • Few-shot loading
  • Scoring config load + normalization
  • Sources collectors + ignore merging (.gitignore + .ctxengignore)
  • Multi-language AST symbol extraction (with stubbed parser test)
  • Semantic scoring cache logic (stubbed; no downloads)
  • Builder advanced flags plumbing

Fixed

• ctxeng/optimizer.py: prevented a potential infinite loop in _smart_truncate() tail trimming.

Changed

• Coverage config updated to omit non-library wiring from coverage measurement:
  • ctxeng/cli.py, ctxeng/__main__.py, ctxeng/integrations/*, ctxeng/watcher.py
• Tests are CI-safe: no optional sentence-transformers requirement.

Install / Upgrade

pip install -U ctxeng
