Decision Log
ChimeraMiND records architectural decisions as immutable, numbered entries (DEC-NNN) in an internal decision log, not as tribal knowledge held by one person. As of this writing the log holds decisions numbered into the DEC-100s, spanning infrastructure, security, and product-architecture calls.
This is the mechanism that lets a new engineer — or an investor's technical diligence team — answer "why does the system work this way?" without a call to the founder.
Representative decisions
| ID | Decision |
|---|---|
| DEC-084 | Non-custodial exchange vault: credentials are encrypted client-side (desktop), never held in plaintext by the backend. See Security & Compliance. |
| DEC-082 | Redis access requires HMAC authentication — internal cache traffic is not implicitly trusted. |
| DEC-078 | ML production pipeline overhaul — model serving decoupled from training, with drift monitoring as a first-class production concern. |
| DEC-077 | Single-session enforcement for authenticated users, closing a class of session-fixation risk. |
How the log is maintained
Every decision entry states the constraint that forced the choice, the alternative considered, and the blast radius if reversed — the same discipline applied to every production change under this platform's engineering rules (INVERT / SENTINEL checks: name what breaks if a change is wrong, and audit both the upstream and downstream of anything touching more than one system boundary).
Why this matters for continuity
A decision log turns "how the system got this way" from a memory into a written, dated record. Anyone with repository access can reconstruct the reasoning behind every non-local architectural call the platform has made — that reconstruction does not require the original decision-maker.
