do_seed now enforces value uniqueness and derives enum values:
- Uniqueness groups (D10): the user-fillable PK, compound UNIQUE
constraints, and single-column UNIQUE / identifier columns stay
distinct across the batch and against existing rows (retry per row).
Junction distinct-combos fall out of PK-tuple uniqueness and cap at
the available parent combinations (logged when capped; the
user-facing note arrives with the advisory in P1.3c).
- Identifier-int columns get a monotonic sequence past MAX(col) (D10),
so they never collide.
- IN-CHECK derivation (D17): a simple `col IN ('a','b')` CHECK becomes
the value source via the new, unit-tested seed::parse_in_check_values,
so the enum-as-CHECK pattern just works.
8 parser unit tests + 4 integration tests (unique column, identifier
sequencing, junction cap, IN-check enum). 2343 pass / 0 fail / 0 skip,
clippy all-targets clean.
Deferred to P1.3c: dedicated SeedResult + capped preview (D18) + the
enum/CHECK advisory incl. the cap note (D12/D13); P1.3d: multi-row path.
The pure generation half of `seed` — no command wiring yet:
- src/seed/: ColumnSpec + Generator model and a seeded StdRng; the
type-gated name-heuristic catalogue (D7) with documented
false-positive guards; table-context name disambiguation (D11);
identifier (D10) and enum-ish (D12) detection; per-type + bounded-date
generators (D8); the hand-rolled product generator (D9); and PickFrom
for IN-CHECK / enum lists.
- Adds the `fake` crate (v5, default features). Verified: single rand
0.10.1 (no duplication), determinism via one seeded StdRng driving
both fake and the hand-rolled generators, security-clean across
osv/grype/trivy.
- ADR-0048 D3 updated to record the dependency verification.
32 Tier-1 tests (exact-value via fixed --seed); 1673 lib tests pass,
clippy all-targets clean.
