Commodity memory spot

Point-in-time daily ledger of Commodity memory spot — every move dated and sourced.

Coverage window

2026-07-12 → 2026-08-27 (387 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.
