Legacy-system knowledge pack — {product}
- Product: … Author: … SME validators: … Version: 0.1.0
Context (C4 level 1)
What the system does, who uses it, and the systems it talks to. Mermaid context diagram.
Containers & modules (C4 level 2)
The major parts and how they're deployed. Module and dependency map.
Data flows
How data moves through the system; where PII lives; external integrations (ACORD, feeds).
Deployment reality
The actual path to production — including every manual step, credential, and out-of-band process. Be honest; this is where the risk hides.
Known gotchas
Traps, workarounds and "don't touch that" knowledge — mined from history by the archaeology skill, confirmed by SMEs.
Buried business rules
Domain rules that live only in code (rating quirks, edge-case handling). Cross-reference the domain brief — these often are the domain brief for a legacy product.
Open risks
EOL components, single points of failure, thin test areas — cross-linked to the debt and security registers.
