WHAT THE COMPANY ALREADY HOLDS
Four systems that are mostly reasoning
A software business generates this without trying. It is the working residue of building and running a product.
Repositories
Commits, branches, and the review discussion attached to each — years of technical judgement with its justification inline.
Incidents
Alerts, timelines, and post-mortems. A complete diagnostic narrative from symptom through cause to fix.
Design and planning
RFCs, architecture docs, Jira and Linear histories showing how scope was argued and what got cut.
Support and success
Ticket threads and escalations, where the product's real behaviour is described by the people hitting it.
