BASELINE · JANUARY 2024
Holly was quiet. For a decade.
A stretch of East Austin sat at composite 41 — below every fund’s screen. Blue-collar bungalows, two corner stores, no new permits filed in eighteen months.
Score 41 · stable for eighteen months.
STAGE 1 · EARLY 2024
Three independent cafés opened. Within 800 meters.
Pioneer-cohort businesses are the canary: a coffee roaster, a second-wave café, an indie bakery. We tag them automatically from new business filings and license records. Three of them inside one corridor — the first hint.
Three pioneers detected within 800 meters.
STAGE 2 · MID 2024
The council repeatedly mentions “mixed-use corridor.”
We parse every municipal hearing transcript across 22 metros. The phrase entered four East Austin hearings in three months. The city’s legislative language always shifts before its zoning does.
The council says it four times in three months.
STAGE 3 · LATE 2024
Eleven permits filed. 2.4× the area baseline.
Demo and interior permits cluster before redevelopment. Eleven along the corridor in ninety days, against an eighteen-month trailing average of 4.5. The signal is now structural, not noise.
Eleven permits in ninety days.
STAGE 4 · MAR 14, 2025
The cascade flipped. A Stage 4 fires.
When all four sub-signals confirm and the composite crosses 85, the cell flips to Stage 4. Pioneer cohort, council language, permit cluster, parcel geometry — all aligned on a single H3 cell in East Austin. The rezoning hearing was already on the docket. Nobody else was watching.
Composite 91 · Stage 4 confirmed.
OUTCOME · MAY 19, 2025
Identified at $3.2M. Sold at $11M.
The council re-upzoned the corridor on May 19 — exactly the language the cascade had been tracking since July. The parcel identified at $3.2M traded at an implied valuation of $11.0M against the new entitlement. 67 days from signal to sale.
$3.2M → $11.0M · 67 days.
