Closes the four audit-surfaced concerns from
paper/narrative_audit_v4.md plus the Opus round-2 N5 interpretive
caveat. All five are prose-level consistency polishings; no
empirical or structural changes.
Concern A (Phase 4 line 31 / §I body): "Script 39c" provenance for
the jittered-dHash claim was less precise than the §III line 59
source-of-truth which (post round-5) attributes the non-Big-4
jittered evidence to a codex-verified read-only spike. Updated §I
to: "cosine: Script 39c; jittered-dHash: Script 39d for Big-4
plus codex-verified read-only spike for ten non-Big-4 firms."
Concern B (Phase 4 line 81 / §V-B): same jittered-dHash claim
without precise provenance. Updated §V-B to match Concern A
attribution + §III-I.4 cross-reference.
Concern C (§III-K.4 line 149): cross-reference to "v3.x §IV-I
corpus-wide version" was stale after v4 §IV-I was shrunk to a
reframing stub. Updated to "§III-L.1 (Big-4 v4 sample) and the
inherited corpus-wide v3.x version cited at §IV-I".
Concern D (Spearman precision): standardized §III-K.1 table at
lines 125-127 to 4 decimal places (0.963/0.889/0.879 ->
0.9627/0.8890/0.8794), matching §IV-F Table IX. Prose floor
language "rho >= 0.879" preserved across Abstract/§I/§V/§VI
since 0.8794 still rounds to 0.879 at 3dp.
Opus N5 / §V-H limit 2 nuance: added a sentence interpreting the
firm-dependent within-firm violation - Firm A's per-firm ICCR is
more contaminated by within-firm sharing than B/C/D's, so the
B/C/D rates of 0.09-0.16 are closer to clean specificity, and the
Firm A vs B/C/D contrast reflects both genuine heterogeneity AND
a firm-dependent proxy-contamination gradient.
Audit artifact paper/narrative_audit_v4.md (~200 lines) captures
the full cross-section coherence check across Abstract / §I /
§III / §IV / §V / §VI:
- Abstract -> body mirror audit (12 claims, all aligned)
- §I 8 contributions -> §III/§IV/§V/§VI mapping (all aligned)
- v3->v4 pivot rhetoric thread (5 nodes, all aligned)
- K=3 demotion / ICCR-FAR / numbers consistency: all verified
- Splice-readiness gate: 10/12 pass + 2 splice-time mechanical
Headline assessment: "Mostly Coherent - submission-ready after
2-3 small patches" (now applied).
