verdict: READY

summary: |
  The plan is a behavior-preserving split of mempalace_code/miner.py (3995 lines) into a
  new mempalace_code/mining/ package, with miner.py reduced to a compatibility shim. The
  task_contract canvas is complete: requirements, surfaces, invariants, risks, and 8
  verification rows are linked to 8 acceptance rows; regression_plan.applies is true with
  4 concrete pytest/ruff command groups; contract_policy is full_spdd with
  sync_gate=required and verification_path=automated. Every test name cited in the AC/VER
  rows was confirmed present in the current tree (test_miner.py, test_chunking.py,
  test_lang_detect.py, test_language_catalog.py, test_treesitter.py, test_kg_extract.py,
  test_watcher.py, test_convo_miner.py). The compatibility-shim policy correctly absorbs
  unlisted-but-affected consumers (tests/test_e2e.py, tests/test_architecture_extraction.py,
  benchmarks/*.py) that only import re-exported names such as mine, scan_project,
  process_file, and load_config. No backlog metadata or archive files are listed as
  implementation targets. Design notes call out dependency direction, lazy-import
  preservation for CLI/MCP startup, scan-rule precedence, KG empty/malformed input
  behavior, and the chunker_strategy/boundary-regex invariants.
