improvement

Diagnostics and privacy cleanup

Import diagnostics, clean JSON export metadata, and local-first privacy notices make upload results easier to inspect and safer to share.

  • Added parser-diagnostics JSON exports for failed imports.
  • Kept exports privacy-safe by omitting raw CSV rows and full uploaded file contents.
  • Clarified the local-first browser flow and localStorage summary behavior.
feature

Lot breakdown transparency

The placeholder FIFO-style simulator now exposes a read-only lot breakdown so users can see how gains and losses were derived.

  • Shows the first matched BUY lots behind SELL transactions.
  • Adds a dedicated lot breakdown CSV export for transparency.
feature

Coinbase parser foundation

Coinbase parser foundation is available for early testing while unsupported rows remain warnings instead of hidden assumptions.

  • Supports basic Coinbase BUY/SELL transaction CSVs.
  • Adds a Coinbase sample CSV and concise parser guidance.
feature

Binance parser foundation

Binance parser foundation is ready for basic Spot trade CSV testing, with Generic CSV still recommended as the fallback.

  • Supports common Binance Spot trade CSV columns.
  • Adds a Binance sample CSV and conservative parser guidance.
feature

Export actions expanded

Users can export simulation-only results, parser diagnostics, summaries, and lot details from the upload flow.

  • Downloads full upload results as JSON.
  • Downloads compact summary CSV and lot-level CSV exports.
feature

Generic CSV upload flow

The core Generic CSV upload flow now runs browser-side parsing, placeholder simulation, and saved summary history for the MVP.

  • Parses the preferred Generic CSV format and legacy sample aliases.
  • Adds upload validation, import quality reporting, normalized previews, and local summary history.
