Clarification requested: historical Spot symbol manifest and daily kline archive boundaries

Hello,

I am documenting a reproducible historical research dataset using Binance Public Data and would appreciate clarification on two archive properties.

1. Historical Spot symbol completeness

Does Binance publish, or retain through an official interface, a complete historical manifest of Binance Spot markets as of a specified date?

Specifically, I need the complete set of Spot markets quoted in USDT as of 2019-09-02 00:00:00 UTC, including symbols that may later have been delisted, renamed, migrated, or removed from current exchangeInfo.

The current exchangeInfo endpoint and the repository’s symbol-discovery helpers appear to return current running symbols. Is there an official dated manifest, historical exchangeInfo snapshot, archive index, or other Binance-controlled record suitable for reconstructing the complete historical symbol set?

2. Daily Spot kline archive containment

For a daily Spot kline archive such as:

data/spot/daily/klines/{SYMBOL}/1d/{SYMBOL}-1d-{YYYY-MM-DD}.zip

is it guaranteed that every included kline has an open timestamp in the half-open UTC interval:

[YYYY-MM-DD 00:00:00 UTC, next day 00:00:00 UTC)

For the 1d interval, is the archive expected to contain exactly one kline whose open timestamp is the named date at 00:00:00 UTC?

I understand that the companion CHECKSUM verifies file integrity. I am asking separately whether the UTC-day containment and one-row 1d semantics are formally guaranteed by the archive-generation process.

A link to authoritative documentation, archive-generation code, or a maintainer statement covering these points would be greatly appreciated.

Thank you.

Start with the current exchangeInfo endpoint, the repository’s symbol-discovery helpers, and the documented data/spot/daily/klines/{SYMBOL}/1d archive path. Check whether the repository exposes archive-generation code or authoritative documentation for historical symbol snapshots, UTC-day containment, and one-row 1d semantics. Done means linking authoritative sources or recording a maintainer-confirmed answer for both questions.
