US point-in-time universe archives (mirror)

Preservation mirrors of two third-party GitHub repositories that together form the only freely available point-in-time record of the US listed-equity universe. Both are single-owner repos and one is already archived read-only upstream, so deletion is one click by a party nobody controls.

This is a byte-for-byte git mirror, not a derived dataset. No cleaning, no filtering, no interpretation.

Bundle	Upstream	Vintages	Span	Upstream status
US-Stock-Symbols.bundle	rreichel3/US-Stock-Symbols	1,407 per exchange	2021-01-30 → 2026-08-20	active
sec-cik-mapper.bundle	jadchaar/sec-cik-mapper	289	2021-12-11 → 2025-02-28	archived read-only

Restoring

Each file is a git bundle containing the complete history. Clone it like a remote:

git clone US-Stock-Symbols.bundle US-Stock-Symbols
cd US-Stock-Symbols && git log --oneline | tail -5

git bundle verify <file> confirms integrity; both were verified as recording a complete history at upload time.

Measured quality

An independent audit of all 4,219 vintage-files in US-Stock-Symbols found:

• Coverage is complete — no gap in 5.5 years exceeds 4 days.
• symbol, name, lastsale, volume are 0.0% missing across every vintage.
• 22 files fail to parse, all dated 2021-01-30 (the repo's first day). Usable history begins 2021-02-01.
• 2021-05-05 is corrupt: sector and industry are 100% missing across all three exchanges simultaneously while prices are intact — a scrape that failed and was committed anyway.
• sector/industry are 18.3% missing before mid-2023, 9.3% after.

Treat sector and industry as unreliable. Treat identity and price fields as sound.
