Curated market prints
Point-in-time daily ledger of Curated market prints — every move dated and sourced.
- Coverage window
- 2026-09-17 → 2026-09-17 (43 rows)Computed from the backing series at page-render time — never typed by hand.
- History honesty
- History accrues in place from the ledger start (2026-06-06) — append-only, never backfilled; depth before the start cannot exist.
- Cadence
- Ledger snapshots daily at 08:00 UTC; movements appear only when a value actually moves. Empty window = nothing moved.
- Revision policy
- Append-only: a frozen day is never edited or deleted (database-enforced). Corrections are registered in data_corrections and served alongside; restatements surface via /api/v1/changes.

- Known gaps
- Known-gaps review pending — the coverage boundaries above are computed and current, but the curator’s qualitative gaps assessment has not been written yet. We state that rather than inventing one.
