Samudra Intelligence Ledger — Entry #2 (Statewide, all 67 Florida counties)

Public ledger of record for Samudra Intelligence's Florida commercial-real-estate prediction program. This version adds Entry #2, the first statewide freeze.

Entry #2 — 617,943 predictions across all 67 Florida counties.
SHA-256 246c32420bb5c07f8a2723d98d1402b7ab2bc2c5c09940f234306c013b0a1f42
Frozen 2026-10-18 and independently timestamped the same day (OpenTimestamps). Window: 18 months. Grades on or after 2028-04-18, against recorded deeds.

What is deposited, and what is not. The digest, metadata, the OpenTimestamps proof, the input manifest and the per-county roll vintage are published here. The frozen prediction CSV is not: it carries raw propensity values, and a live book is product. On grading day it is published verbatim, and shasum -a 256 on it must reproduce the digest above. If it does not, the book was altered and every claim built on it should be discarded.

On the 2026P roll vintage. Florida DOR deletes preliminary tax rolls from its portal once Final is posted. At freeze time, 2026 Final existed for only 48 of 67 counties — and not for Miami-Dade or Broward — so the only way to freeze a uniform statewide book was the preliminary vintage, which the source has since withdrawn. A third party therefore cannot re-download our inputs. So the inputs were hashed instead: all 134 input files are listed with their SHA-256 digests in INPUTS_SHA256SUMS_2, archived under object-lock storage, and verified 134 of 134 by re-download and re-hash. Per-county vintage is in PER_COUNTY_VINTAGE_2026P.json.

What this book cannot claim. Deed history is not uniform across Florida. Thirteen counties have records back to 2015; the other 54 begin 2025-01-01. Walk-forward backtest folds before 2024 are therefore observable in only those 13 counties, and any lift quoted from them is a 13-county figure, not a statewide one. The first substantially statewide fold is 2025-01-01, at 17 of 18 months observable. Entry #2 has not been graded. Nothing in this deposit is a result.

Entry #1 (Founding Book) remains in this deposit unaltered: 323,522 predictions, 11 counties, frozen 2026-08-20, SHA-256 036c4c5d4bc71793569e67f0b1697663cfc42211c467304a16e14756512a82d6, grading on or after 2028-02-20. Entries are append-only; no entry is ever edited or removed.
