Source maps are draw.io XML, embedded here live rather than as flat images — the diagram you see below renders straight from the same file that's checked into git, so there's nothing to keep in sync between the map and the page.
The cloud delivery value stream: code moves from DEV to UAT to PROD, gated by SLIs, SLOs, and SLAs, with error budgets marking the handoff from feature work to reliability work. DevOps practices cover the non-prod stages; SRE practices take over once something reaches PROD, with a shared band in between where both are accountable.
A dependency map for the DEV stage of the value stream above: what it takes to get a verified local dev environment. bash and linux sit as commodity — not worth building, just depended on. The interesting work is the custom-built-to-product band above them: greenTest's bootstrap scripts and notebook, verified against vanilla compost or whichever repo you're actually working on.
