For reviewers

TODO: Tag the decision-makers. List strategic decisions with links to specific lines (use branch URL, not commit URL, so links stay current: ?plain=1#Lstart-Lend). List technical decisions separately if different audience. Point to the “Proposed JIRAs” section for JIRA review.

Doc structure note: The decision and JIRA sections of the spike doc are where your input is needed. They link to background sections later in the doc — read those if you need more context on a specific point, but it is optional.
