Chameleon

Fixed

• Refresh now repairs a damaged enforcement.json instead of preserving it.
  A corrupt enforcement file — or a valid object whose block_rules is not a
  dict — made active_block_rules fall open to an empty set, silently voiding
  all block-rule enforcement while mode=enforce still read as healthy, and a
  normal refresh noop-preserved the damage. The repair predicate now requires
  enforcement.json to parse to a dict whose block_rules is itself a dict, so
  /chameleon-refresh re-derives and restores it.
• Refresh now repairs a corrupt Ruby constant_index.json. The Ruby
  cross-file constant graph (the analogue of the TypeScript/Python symbol
  indexes) was missing from the repair set, so a corrupt one silently killed the
  cross-file existence-break advisory, get_blast_radius, and
  get_contract_breaks with no recovery path. It is now validated and repaired.
• Refresh now repairs corrupt Python exports_index.json /
  reverse_index.json and an empty profile.summary.md. The symbol-index
  repair check was TypeScript-only; Python writes these indexes too. The summary
  check was existence-only.
• The Python extractor no longer drops large valid files. The libcst node
  ceiling counted dense CST nodes against a cap meant for sparser AST nodes, so a
  valid sub-1 MB file (≈3500 lines) was silently skipped. The cap is retuned to
  libcst density; MAX_FILE_SIZE remains the real bound.
• The status line strips box-drawing characters from cached profile fields,
  so a poisoned cache name can no longer forge a │-delimited trust segment.
• get_callers documentation now credits Python import-grade callers (the
  docstrings said the import grade was TypeScript-only; Python emits it too).
