Testing & Quality
View on GitHub

Investigate and fix PokeSwift gameplay parity regressions against `pret/pokered` using the repo's source-driven pipeline. Use when a user reports behavior drift from Pokemon Red, asks for parity work in battle/progression/maps/save/load/audio/UI, needs tracing from pokered assembly and data through `PokeExtractCLI`, `Content/Red`, and `PokeCore` or `PokeUI`, or wants a PokeSwift parity review or fix instead of generic Swift refactoring.

Pokeswift Parity Fix

Read AGENTS.md and SWIFT_PORT.md before changing milestone-sensitive behavior.

Prefer source-driven fixes. Do not patch runtime behavior if the real defect lives in extraction, generated content, or a broken contract between modules.

Workflow

  1. Define the exact parity target. Capture the user-visible behavior that should match Red. If the report is vague, anchor it to a concrete flow: map transition, trainer battle, move effect, blackout, evolution, audio cue, save/load path, or UI presentation beat.

  2. Reproduce before editing. Start with git status --short. Read the owning implementation instead of guessing. Use the smallest reproduction that proves the bug: focused tests, telemetry traces, or a native app run.

  3. Trace the ownership chain. Use this order whenever behavior originates from Red: pret/pokered asm/data -> PokeExtractCLI -> Content/Red -> PokeContent/PokeDataModel -> PokeCore -> PokeUI/PokeMac. Stop at the first layer that diverges from expected behavior and fix that layer.

  4. Patch the narrowest correct boundary. Change extractor code if generated content is wrong. Regenerate Content/Red/** instead of hand-editing generated artifacts. Change PokeDataModel first if a shared schema contract is wrong. Keep PokeCore headless; keep host/UI concerns out of simulation code.

  5. Validate at the correct level. Use focused extraction/content tests for extractor changes. Use focused runtime or UI tests for consumer changes. Run the native app when milestone-sensitive behavior is involved. Update SWIFT_PORT.md in the same change set when scope, milestone status, or a meaningful parity boundary changes.

Ownership Guide

  • PokeExtractCLI Own parser, normalization, and generated manifest bugs. Search here first for missing trainer text, wrong warps, map scripts, item data, encounter tables, audio metadata, and battle templates.

  • Content/Red Treat as generated evidence, not authoring surface. Diff it to confirm extraction output, but fix the extractor and regenerate.

  • PokeDataModel and PokeContent Own schema and loading contracts. Use this layer when extraction is correct but runtime sees missing or mis-modeled fields.

  • PokeCore Own gameplay simulation, battle rules, progression flags, persistence, and telemetry production. Fix here when the manifest is correct but runtime semantics drift from Red.

  • PokeUI and PokeMac Own native presentation, rendering, app shell, and input/host behavior. Fix here only when the underlying runtime state is correct and the visible behavior is wrong.

File Checklist

Validation Matrix

  • If Tuist manifests or source moves changed: Run tuist generate --no-open.

  • If extractor logic or generated content changed: Run ./scripts/extract_red.sh. Then run focused PokeExtractCLITests and PokeContentTests.

  • If runtime logic changed: Prefer workspace xcodebuild over swift test. Use the smallest relevant test slice first, then broaden as needed.

  • If UI or rendering changed: Run focused PokeUITests or PokeRenderTests, then build PokeMac.

  • If the bug is only credible through native execution: Use POKESWIFT_WATCH_MODE=0 ./scripts/launch_app.sh. Probe telemetry endpoints such as /health and /quit when relevant.

Failure Shields

  • Do not introduce runtime .asm parsing.
  • Do not hand-edit Content/Red/**.
  • Do not classify compile success as parity proof.
  • Do not use swift test at repo root; this repo validates through the workspace.
  • Do not rewrite broad runtime/UI areas when a single extractor or contract bug explains the issue.
  • Do not ignore dirty files; work around unrelated changes and keep your diff scoped.

Review Mode

When asked to review a parity patch instead of fixing it:

  • Start from git status --short and git diff --stat.
  • Prioritize regressions that break Red behavior, extraction fidelity, schema contracts, or native validation.
  • Cross-check suspicious behavior against pret/pokered assembly/data before calling it a bug.
  • Prefer findings with a concrete ownership path: wrong extractor output, wrong generated artifact, wrong runtime rule, wrong presentation contract, or missing test coverage.

Output Expectations

Report these points clearly:

  • expected Red behavior
  • first diverging layer
  • files changed and why
  • validation run
  • whether SWIFT_PORT.md was updated or intentionally left unchanged
