The fixture gap (the 4.7.1 / 5.6.1 precedent): no existing large seed builds reporting-shaped data. A scripts/seed-reporting.ts (+ pnpm db:seed:reporting) constructing the corpus through the shipped services (the no-raw-inserts rule, doubling as a bulk smoke test of every Epic-6 write path), with ONE recorded deviation: a documented timestamp back-dating pass (created/resolved/revision timestamps are server-set and no service accepts them; the pass is confined to this script, touches timestamps only, and the self-check asserts the resulting spread).
The corpus: 10k issues (cap-parameterised env var; the CI lane runs reduced — the board-at-scale cap precedent) spread across ~26 weeks of created/resolved history with realistic weekly variance (the created-vs-resolved report needs real buckets), full spread over status/priority/assignee/kind, label + component + all five custom-field types valued on meaningful subsets (the 6.1 predicates need selective matches, not all-or-nothing), a long-tail of resolved issues for the status-distribution report. Plus the Epic-6 entities: 5+ named saved filters (6.2) spanning enum/negation/date-window/CF predicates, one populated dashboard (6.3) whose widgets consume them, and 3+ enabled automation rules (6.6) over the built-in action set. Deterministic (the FNV-hash convention — no Date.now/random; stable across reseeds). Fixture helpers (tests/e2e/_helpers/reporting.ts): accessors for the corpus counts AND the expected aggregates (weekly created-vs-resolved buckets, the status distribution) computed independently from the deterministic spread — the values the 6.7.3 report asserts compare against.
pnpm db:seed:reporting builds the corpus + saved filters + dashboard + rules idempotently through the shipped services (re-run converges; any service error fails loudly), deterministic, cap-parameterised with the CI lane reduced.pnpm test:coverage holds on shared helpers.db:seed:large (2.5.16), seedLargeBoard (3.5.1), the 4.7.1 sprint seed, db:seed:collab (5.6.1) — the cap/CI-lane + determinism patterns
