Adopt settled-reach's Q&D record convention. Confirmed decisions
live under decisions/<domain>.md as D-NNN; open questions under
questions-<domain>.md as Q-NNN; rejected alternatives in rejected.md
as R-NNN. Markdown is source of truth; .pql/pql.db (added later) is a
query index.
Backlog captured from the Tier-0 Flutter planning sessions: bare
WidgetsApp, theme pipeline, kernel admission rule, feature-first
layout, a11y + i18n as Tier-0 contracts, test pyramid, kanban over
Scrum, pql-owns-planning, Python stopgap sunset clause.
ADR migration (D-001, D-003-D-006 confirmed, R-002 rejected) is
staged for the next commit so the diff stays readable.
