Same fix as v2.31.13's paper §6 ¶3 and the protocol.py docstring sync:
the README's "0.05-0.18 / 0.43-0.99" calibration ranges were the
same loose values that v2.31.13 corrected. Updated to match the actual
audit data: BP/EP in [-0.04, +0.12], degenerate up to +0.99 with 5/9
above the 0.30 cutoff.

Now the paper §6 ¶3, protocol.py docstring, and protocol/README.md
all agree on the (c) calibration ranges.

Codex round 15 #1 priority for the E&D-track paper:
  - protocol/protocol.py: 4 diagnostics (residual norms, BP grad norms,
    cross-batch direction stability, and a frozen-baseline comparator)
  - protocol/report.py: DiagnosticReport with per-diagnostic verdicts and
    pretty-printer
  - protocol/smoke_test.py: validates BP/DFA/EP checkpoints produce the
    expected verdicts (BP/EP trustworthy; DFA walked back via residual
    explosion + BP grad at floor)
  - protocol/README.md: usage, audit cases, threshold rationale
  - protocol/CHECKLIST.md: 6 evaluation pipeline pitfalls (norm(-1),
    cosine_similarity eps clamp, fp16 underflow, Bs reproducibility,
    aggregation, layer-0 dominance)
  - protocol/REPORTING_TEMPLATE.md: per-method fillable form for FA papers
