SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Establish fixture-based tests covering every `public`/`open` `func`/`var`/`init` declared under `Sources/MachOSwiftSection/Models/`, with cross-reader equality assertions (MachOFile/MachOImage/InProcess + their `ReadingContext` equivalents) and full ABI literal expected values pinned in git. + +**Architecture:** Four pillars. (1) `MachOSwiftSectionFixtureTests` base loads `SymbolTestsCore.framework` from disk *and* `dlopen`s it into the test process, exposing `machOFile`, `machOImage`, three `ReadingContext` instances. (2) Per-method `@Test` Suites under `Tests/MachOSwiftSectionTests/Fixtures/` mirror the `Models/` directory; each `@Test` does cross-reader equality + reference to a baseline literal. (3) `baseline-generator` executable target reads fixture via MachOFile path, emits `__Baseline__/Baseline.swift` literal data files committed to git. (4) `MachOSwiftSectionCoverageInvariantTests` uses SwiftSyntax to scan `Models/` source and reflects all `FixtureSuite`-conforming Suites; missing/extra members fail the build. + +**Tech Stack:** Swift 6.2 / Xcode 26.0+, swift-testing, SwiftSyntax + SwiftParser + SwiftSyntaxBuilder (already a Package.swift dep), MachOKit, dlopen/dlfcn, ArgumentParser. + +**Code generation strategy:** Baseline files are produced via SwiftSyntaxBuilder's string-interpolation form (`SourceFileSyntax(stringLiteral:)` + `\(literal:)` / `\(raw:)`). SwiftSyntax parses the interpolated source, rejecting any malformed syntax at generation time, and `.formatted()` normalizes indentation/whitespace. A small `BaselineEmitter` helper covers cases `\(literal:)` doesn't natively support (hex literals — Int default to decimal in `\(literal:)`). + +**Branch:** `feature/machoswift-section-fixture-tests` (already created from `feature/reading-context-api`). + +**Spec reference:** `docs/superpowers/specs/2026-05-03-machoswift-section-fixture-tests-design.md`. + +**Prerequisites:** Before any task, run `swift package update` from the repo root to ensure SPM dependencies are current (per CLAUDE.md).
