TK-10993: track read-only Track-C roll-leak enumerator (produced the already-committed data/genuine-rollleaks.json in d3daab6)

51a533bf4119dac179d66feb8a7c00482e2a4d0a · 2026-09-03 14:00:53 -0700 · Steve Abrams

Resolves the 'unknown-owner dirty enumerator' blocker that held TK-10993:
the file is the READ-ONLY enumerator whose output was committed by the
auto-data-snapshot job on 2026-08-31 but whose source was never added.
No behavior change; nothing external touched.
