PITO/DIDO is the narrative compression layer over the four-pillar matrix, not a replacement
Attribution
Prior state
Tomas proposed structuring the Fab City Index around PITO and DIDO
sub-indices. Open question: do they replace the four-pillar ×
five-scale matrix, or compress it?
Change
PITO and DIDO are the narrative compression layer on top of the
four-pillar × five-scale matrix — not a replacement.
PITO (Products In, Trash Out) — metabolic signature of linear-extractive
city; throughput, imports, waste outflows. Operationalises H₀-T.
DIDO (Data In, Data Out) — metabolic signature of regenerative-distributed
city; open data, fab-lab capacity, transparency, distributed
manufacturing.
Formula: FCI_t = DIDO_t · (1 − PITO_t) · κ_t (snapshot);
ΔFCI/Δt is the trajectory PLANETAI actually measures.
κ = coupling coefficient, operationalises H₀-A (action latency).
Reasoning
Mayors and ministers cannot hold 20 cells in their head; the
four-pillar × five-scale matrix is the calculator, not the
dashboard. PITO/DIDO is canonical Fab City vocabulary from Tomas
Diez's founding-period writing (Fab City Whitepaper, 2016). Using
it as the narrative axis preserves methodological resolution
(matrix as instrument) while making the story carryable.
Boeing's 37/100 (2024) and Utopies' 37.58/100 (2018) for the best
Western city are both recovered as the single-cell
(Economic × Region/City), snapshot, κ-implicit projection of the
full FCI. Same instrument, less resolution. This recovery is the
lineage defence for v18.
Bali under PITO/DIDO is high-DIDO / partial-PITO — a feature, not
a Metroverse-coverage liability. The DIDO side is computable from
Smart Citizen, fab labs, and community-council infrastructure
without customs data.
