Architectural Smells and Anti-Patterns in Modular Monolith Applications: A Multivocal Literature Review

Replication package for the paper "Architectural Smells and Anti-Patterns in Modular Monolith Applications: A Multivocal Literature Review" (Carvalho, Bezerra, Fook and Neto), accepted at the 22nd International Conference on Web Information Systems and Technologies (WEBIST 2026). The paper reports a multivocal literature review across six digital libraries and the grey literature (32 included sources: 19 primary studies and 13 grey sources) and proposes a catalog of seventeen architectural smells for modular monolith applications, each classified against the consolidated microservices anti-pattern catalogs as inherited, transformed, or novel, and paired with a build-time detection mechanism expressed as an architectural fitness function. This package supports the transparency and reproducibility of the review. It contains: the registered review protocol with its amendment log (protocol.md); the per-database search strings, dates, and hit counts feeding the PRISMA flow (search-strings.md, prisma-search-log.md); the coded source corpus with screening decisions, grey-literature quality tiers, per-smell supporting sources, and the record-level inclusion status reproducing the 19+13 included set (corpus.xlsx); the seventeen-smell catalog with counterparts, relations, and detections (catalog.md); the two inter-coder reliability instruments and the agreement computation for both coding rounds, including Cohen's kappa (coding-form-round1.xlsx, coding-form-round2.xlsx, kappa-scoring.xlsx); and the executable rule configurations for the fitness functions of the paper's worked example: boundary lint, module cycle gate, schema-scoped accessor rule, and the table-to-module ownership manifest (checks/).
