Package baseline tracks codefit's view of a project's audited surface across scans.

Package cache defines the content-hash finding cache (PRD section 15, optimization 2).

Package context defines AuditContext, the immutable struct that carries everything a sensor needs about the project under audit: where it lives, its language and framework, the parsed config, and the run modifiers (incremental ref, no-LLM mode).

Package coverage models codefit's coverage manifest (PRD section 10, RF-07): the explicit, per-language declaration of what codefit detects and what it does not.

Package crossrules is codefit's family of deterministic checks that reason over BOTH neutral inputs at once — the schema (db.Schema) AND the code's query filters (query.QueryFilter) — the code↔schema cross that index-vs-query needs (ADR 0029).

Package cve checks project dependencies against known vulnerabilities via OSV.dev (PRD section 18, RF-09).

Package db is codefit's neutral, format-agnostic model of a database's structure — the schema a DB-dimension rule reasons over, blind to where it came from (Prisma or SQL-DDL — both parsers ship today).

Package dbcoverage holds the DB dimension's coverage prose — what the rules in core/dbrules actually detect, in the same plain-prose form the coverage manifest uses (PRD §10, RF-07).

Package dbrules holds codefit's deterministic database-structure rules.

Package dwrules is the paradigm-aware DW (data-warehouse) rule family: a SEPARATE two-argument Rule family from dbrules.Rule (schema-only), mirroring how internal/core/crossrules solved "a rule needs a fact beyond the bare schema" (ADR 0029) without mutating dbrules.Rule.

Package findings defines the universal, language-agnostic vocabulary of an audit: the Finding hallazgo, its Severity and Dimension, the ConsentRecord that authorizes suppressing a critical security finding, and the SensorResult every sensor returns.

Package paradigm computes a database schema's analytic-vs-transactional paradigm and each table's warehouse role, as a pure function over the neutral internal/core/db model.

Package pipeline defines the filtering pyramid (PRD section 15): cheap layers run first and only what they cannot conclude is escalated to the next, more expensive layer.

Package query is codefit's neutral, format-agnostic model of a database query filter issued from application code — the CODE side of the code↔schema cross (index-vs-query), mirroring how internal/core/db models the SCHEMA side.

Package report defines the canonical audit report and the renderers that present it.

Package ruleengine is codefit's own matcher for a subset of the Semgrep rule format (PRD section 17).

Package scoring computes the per-dimension scores (0-100) and the weighted global score from a set of findings, using the configurable weights from .codefit.yaml (PRD RF-07).

Package sourcetext decodes the RAW BYTES of a file codefit was asked to read into the UTF-8 text every layer above it assumes it already has.

Package surface is the core framework for surface mapping (PRD section 10): the language-agnostic home for surface categories and, in Fase 1, the SurfaceQuery format (codefit's own declarative format for enumerating auditable structural surface, distinct from the Semgrep-format rules used for deterministic findings — PRD section 17).

Package syntax is codefit's parser-agnostic AST boundary.
