v0.4.0 — Production-Ready Hardening Complete

What's New

Phase 5: Extended Diagnostics and Exports

• /sherpa export json|csv — Export lifetime stats as structured JSON or CSV
• Context-aware nudge escalation — Repeated errors trigger progressively stronger nudges
• Structured error fields — Tool errors carry status, error_type, and error_message
• MCP tool repair — Did-you-mean suggestions plus schema repair for all registered tools

Phase 4: Reliability and CI

• Alias handler dispatch fix — Corrected tool-name alias resolution
• Benchmark in lint scope — benchmark.py now passes make lint and make format
• CI fixes — Line endings, model_tools import, flaky log test all resolved

Phase 3: Documentation and Honesty

• Honest benchmark rewrite — Zero-data reports show NO REAL DATA banner instead of fabricated numbers
• README/CONTRIBUTING/docstring sync — All docs now match actual runtime behavior

Phase 2: Stability

• Uniform fail-open wrappers — All 6 hooks swallow exceptions gracefully
• Single-lock _update_state — Eliminated triple-flock pattern
• Windows and profile isolation — HERMES_HOME resolved via get_hermes_home()

Phase 1 and 0: Windows Baseline

• State-dir creation — Auto-creates state directories on Windows
• cd-path corruption fix — Working directory no longer corrupted

Stats

• 194 tests passing
• Cross-platform: Windows (fcntl/msvcrt) and Unix
• Python 3.9+
