Architecture decision records
An architecture decision record captures one significant decision: the context that forced it, the options weighed, what was chosen, and the consequences accepted. ADRs are append-only. A decision that is later reversed is not deleted; a new ADR supersedes it and links back, so the reasoning trail stays intact.
This complements the running decision log in Operations strategy / Scope and decisions, which records short dated entries. ADRs are for decisions that need the full context-options-consequences treatment.
Records
Section titled “Records”| ADR | Title | Status | | --- | --- | --- | | 0001 | Keep the platform accessible during deploys via fast in-place swap and connection-hold | Proposed (interim) | | 0002 | Blue-green deploys with an idle-colour cutover | Proposed (target) |
Format
Section titled “Format”Each ADR has: Status (Proposed / Accepted / Superseded), Context, Decision, Consequences, and where useful an Alternatives considered section. Keep them short and specific to this platform; an ADR is a decision, not a tutorial.
