GPT-5.6 Sol (Codex) on Remove dead JavaScript exports

Passed in 35s. Attempt 3. Run 20260904T113808Z-gpt-5-6-sol-dead-code-3.

Task

Remove dead exports

This small Node project has six exports under src/ that are unused everywhere. Remove the dead code without removing any export that the project uses.

Two exports are easy to misclassify because they are used only by another function in their own file. They are live and must stay. Every other live export is imported by another source or test file.

There is no report to write. The output is the cleaned src/ folder, and this command must stay green without installing anything:

node --test test/

Command

# Remove dead exports

This small Node project has six exports under `src/` that are unused everywhere. Remove the dead
code without removing any export that the project uses.

Two exports are easy to misclassify because they are used only by another function in their own
file. They are live and must stay. Every other live export is imported by another source or test
file.

There is no report to write. The output is the cleaned `src/` folder, and this command must stay
green without installing anything:

` ` `sh
node --test test/
` ` `'

Output

Removed all six unused exports from `src/` while preserving live same-file helpers.

`node --test test/` passes: 3/3 tests.

I’m using the Atris build workflow because this is a focused code cleanup. I’ll inspect its instructions and TASK.md, remove only proven-dead exports, then run the test command.

name: atris-build
description: Build-phase execution policy for repos using the Atris workflow. Use for focused implementation work after plan is set (frontend/backend/task execution). Use when user asks for coding, refactors, UI tweaks, or explicit "build" context.
---

# Atris Build Skill

## Scope
- Use in repos where `atris/` is present.
- Apply when the user asks for implementation work: UI changes, feature edits, bug fixes, or task execution.
- If intent is unclear, ask one clarifying question before touching files.

## Operating rules
- Run only the build work approved by the user.
- Keep edits surgical and minimal.
- Avoid broad refactors unless explicitly requested.
- Do not run tests/validation unless explicitly asked.
- Do not run destructive commands or revert unrelated edits.

## Process
1. Confirm target behavior and acceptance criteria.
2. Map required files from `atris/MAP.md`.
3. Implement in small chunks with no speculative side work.
4. Preserve existing structure/patterns in the touched domain (`frontend`, `backend`, etc.).
5. Report exact file paths changed and why.

## Frontend notes
- Preserve established design direction in existing files.
- Prefer minimal DOM/CSS motion changes over full redesigns.
- Keep mobile-first space conservation in mind before adding new chrome.

## Closure
- Summarize changes and remaining open questions.
- If work is incomplete, capture next explicit step.

This folder has no Atris map, so that workflow doesn’t apply beyond its general “surgical edits” guidance. The project is tiny; I’m tracing every exported symbol across source and tests, including same-file calls.

The six dead declarations are removed. I preserved `normalizeWhitespace` and `roundTax`, the two helpers whose only callers are in their own files; now I’m validating both tests and the remaining export/import graph.
