Card: the full archive's tables, joins, scale and licence

Adds what researchers asked after reading the sample: the other tables (events, signatures, holder balance changes, the completeness receipt), the (slot, idx) join, block time only, a month's size, and what the licence allows for the full files. No prices.

+## The full archive
+
+This sample is one day of the trades table. The full archive has every day since pump.fun's first day, as daily Parquet, and four more tables beside it:
+
+| table | one row per | columns |
+|---|---|---|
+| events | a create, completion, migration or pool | `slot`, `idx`, `ts`, `kind`, and per kind: for a create, the mint, the creator field, the paying wallet, name, symbol and supply; for a migration, the mint, pool, tokens and SOL |
+| signatures | a transaction | `slot`, `idx`, `signature` |
+| holder balance changes | a change in any wallet's balance of a pump.fun coin, by trade or transfer | `slot`, `idx`, `mint`, `owner`, `after`, `delta` |
+| completeness receipt | a UTC day | first and last slot, blocks, slots the chain skipped, rows per table |
+
+- **Joins:** every table carries `slot` and `idx`, and the signatures table joins all of them on that pair, this sample's trades included. Several trades in one transaction share its signature.
+- **No first-seen time:** the archive is read from Solana's ledger, not recorded from a stream, so block time is the only time.
+- **Scale:** September 2026 was 821.1 million landed trades (about 30 GB), 358.0 million failed trades (2.8 GB), 2.0 million events (0.2 GB), 1.09 billion signatures (74 GB) and 941.6 million balance changes (17 GB), across 8,828,944 blocks.
+- **Licence of the full files:** internal research use; aggregate results (statistics, charts, backtest results, findings) are yours to publish, but not the rows, or datasets that could stand in for them. This sample stays CC BY 4.0.
