Independent AI code review (not external peer review)

No theorem-invalidating implementation defect found. Fresh full reproduction and independent exact checks pass. Two minor robustness/coverage findings were fixed in reviewed candidate.

Fresh reproduction: PASS_FRESH_REPRODUCTION. Own exact arithmetic checks: 1019 PASS.

mesh-progress: Original arbitrary --width below Decimal resolution could leave x unchanged and loop indefinitely. Published 0.00002 mesh unaffected. Reviewed candidate requires end>x. Executed width1e-100 and confirmed immediate ArithmeticError with no output certificate.

auxiliary-evidence-binding: Original wrapper did not check second witness and no-quintic outputs, locator source hashes, or explicit witness center/polynomial bindings. Underlying examples pass actual rerun. Reviewed candidate now checks all three locator center/status/source bindings, negativity/positivity signs, and explicit ordered-pair polynomial metadata. Inspected exact source additions.

Analytic inspection:
- Directed Decimal add/multiply/division use separate ROUND_FLOOR/ROUND_CEILING contexts; unary sign uses exact copy_negate. Fraction grid encloses both endpoints.
- Exponential omitted Taylor terms have positive ratio bounded by u/(L+2); reciprocal and squaring preserve inclusion. All current certified arguments are below512.
- R recursion reproduces differentiated factor; C formula is x derivative of B. Largest n power is26 for C10; common geometric ratio bounds all omitted terms n>=8 on x in[3,4].
- Moment normalization, signs, mixed tails and tail-tail products are retained. E and G minors enforce lower-degree positivity.
- Schur derivative and expanded determinant derivative agree algebraically. Rational replay shares B/C assembly and does not count as independent derivation. Ordered-pair pointwise code independently expands finite product coefficients.
- Fresh source-only reproduction under Python -B -O passes 1000-cell Decimal certificate, 1000-cell Fraction replay, both rational root endpoints, witness examples, and printed claim checks.

Limitations:
- Arithmetic fuzz tests are finite checks, not a replacement for analytic inspection.
- The exact rational replay intentionally shares analytic moments with primary verifier.
- General termination theorem requires adaptive exponential range reduction once truncation grows beyond fixed scaling; reviewed mathematical author handles wording.
- AI subagents are not human referees; no worldwide originality priority finding made by this code audit.
Cleanup: exact own scratch E:/luminary-scratch/riemann-c-independent-code-20261017 remains; tool rejected deletion as blocked by policy. All unique evidence was byte-verified on D. No deletion occurred and no retry/bypass was attempted.
