Entroly — Production Edge-Case Test Suite
==========================================

Focus: gaps NOT covered by existing tests/test_functional.py.

Tests added here:
  P-01  CONTEXT EFFICIENCY METRIC    stats() exposes correct key + math
  P-02  SLIDING WINDOW RECALL        window caps, 0=disabled, window > N
  P-03  MCP SERVER TOOL LAYER        ingest_fragment / optimize_context / recall_tool via Python layer
  P-04  GC FREEZE STATE              gc is disabled after engine __init__; re-enabled after optimize
  P-05  AUTOTUNE CONFIG I/O          json round-trip, weight normalization, bounds
  P-06  DAEMON CONTROL               enabled / disabled flag respected
  P-07  UNICODE + BINARY-LIKE        non-ASCII content ingested and recalled
  P-08  EMPTY CONTENT                empty string ingest handled gracefully
  P-09  ZERO TOKEN BUDGET            optimize(0, ...) returns valid response
  P-10  ALL DUPLICATES CORPUS        100% dupe corpus → still optimize works
  P-11  RAPID CONCURRENT INGESTS     threading doesn't corrupt fragment count
  P-12  RECALL WINDOW > CORPUS       window larger than N fragments = same as no window
  P-13  EFFICIENCY MATH EXACTNESS    cumulative_information / tokens = context_efficiency
  P-14  PRISM DRIFT GUARD            10 feedbacks → weights still in (0,1) simplex
  P-15  BENCH EVALUATE CONFIG        bench/evaluate reads updated tuning_config correctly
  P-16  MAX_FRAGMENTS EVICTION       fragment_count never exceeds max_fragments
  P-17  EXPORT/IMPORT ROUNDTRIP      export → import restores engine state faithfully
