Reading the record
What the seed record supports.
This project is part of the fifteen-record exploratory sample used to test SPICE’s protocol, evidence hierarchy, and provisional codebook.
Inclusion in the matrix means an eligible source was identified for that code. It does not, by itself, establish a single cause or assign responsibility.
Recorded codes
6 provisional patterns in this record.
Each code is a documentary signal, not a stand-alone causal conclusion.
Baseline optimism / strategic presentation
Favourable baseline assumptions or presentation are recorded only where supported by inquiry, audit, regulatory, or equivalent documentary evidence.
P03Site or geotechnical uncertainty
Ground, site, or subsurface conditions materially differed from the knowledge available to the project baseline.
P06Indigenous rights, consultation, litigation
Rights, jurisdiction, consultation, accommodation, or litigation are recorded as project-definition and legitimacy questions, never as a generic delay cause.
P10Weather or natural hazards
Weather or natural hazards materially affected work, access, safety, schedule, or cost.
P13Regulatory, permitting or compliance
Regulatory review, permitting, approvals, or compliance obligations materially shaped the project.
P14Scope or late-design change
Scope evolution, immature definition, or design change materially affected delivery and is traced to its upstream conditions.
Provenance
A record that shows its limits.
