# U3 sqlite-tier task fixture (spec §5). The official reference `sqlite`
# server is not currently present in github.com/modelcontextprotocol/servers
# (checked at commit d31124c, 2026-07-06) — see servers/sqlite_server.py's
# module docstring for the disclosed fallback used instead.
# Fixture: u3_sqlite/fixture.db — two tables, "employees" (3 rows) and
# "inventory" (2 rows), deterministic content.
# {root} is substituted at runtime with the sandboxed copy's absolute path;
# every tool operates on {root}/fixture.db via $QUANTMCP_U3_ROOT, so no task
# instruction actually needs to mention the path (unlike the filesystem/git
# tiers, whose tools take an explicit path argument).
# Instructions are phrased naturalistically and never name the tool to
# call, for the same reason as the U1/U2 tasks.
# `tool:` on each task (Phase 7) declares which tool that task is designed
# to exercise, for the per-tool SCI-vs-Δ regression (H2) -- all 4 sqlite
# tools already had task coverage, so no new tasks were added here; only
# the tool metadata is new.
