 ### Phase 6 — SUnit + corpus to 200+
 - [x] Port SUnit (`lib/smalltalk/sunit.sx`). Written in Smalltalk source via `smalltalk-load`. Provides `TestCase` (with `setUp` / `tearDown` / `assert:` / `assert:description:` / `assert:equals:` / `deny:` / `should:raise:` / `shouldnt:raise:` / `runCase` / class-side `selector:` and `suiteForAll:`), `TestSuite` (`init`, `addTest:`, `addAll:`, `tests`, `run`, `runTest:result:`), `TestResult` (`passes`/`failures`/`errors`, counts, `allPassed`, `summary` using `String>>format:`), `TestFailure` (Error subclass raised by assertion failures and caught by the runner). 19 tests in `lib/smalltalk/tests/sunit.sx` exercise pass/fail counts, mixed suites, setUp threading, and should:raise:. test.sh now loads `lib/smalltalk/sunit.sx` in the bootstrap chain (nested SX `(load …)` from a test file does not reliably propagate top-level forms).
-- [ ] Vendor a slice of Pharo `Kernel-Tests` and `Collections-Tests`
+- [x] Vendor a slice of Pharo `Kernel-Tests` and `Collections-Tests`. `lib/smalltalk/tests/pharo/kernel.st` (IntegerTest / StringTest / BooleanTest, ~50 methods) and `tests/pharo/collections.st` (ArrayTest / DictionaryTest / SetTest, ~35 methods) hold the canonical Smalltalk source. `lib/smalltalk/tests/pharo.sx` carries the same source as strings (the `(load …)`-from-tests-files limitation we hit during SUnit), runs each test method through SUnit, and emits one st-test row per Smalltalk method — 91 in total.

+- 2026-04-25: Pharo Kernel-Tests + Collections-Tests slice + 91 pharo-style tests (`tests/pharo/{kernel,collections}.st` + `tests/pharo.sx`). Each Smalltalk test method runs as its own SUnit case and counts as one st-test toward the scoreboard. 751/751 total — past the Phase 6 "200+ green tests" target.
 - 2026-04-25: SUnit port (`lib/smalltalk/sunit.sx`, `lib/smalltalk/tests/sunit.sx`) — TestCase/TestSuite/TestResult/TestFailure all written in Smalltalk source via `smalltalk-load`. Full assert family + should:raise: + setUp/tearDown threading. 19 tests verify the framework. test.sh now bootstraps SUnit alongside runtime/eval. 660/660 total.
 - 2026-04-25: String>>format: + universal printOn: + 18 tests (`lib/smalltalk/tests/printing.sx`). `format:` does Pharo {N}-substitution; `printOn:` routes through user `printString` and coerces to a String for iteration. Phase 5 complete. 638/638 total.
 - 2026-04-25: Number tower + Fraction class + 47 tests (`lib/smalltalk/tests/numbers.sx`). 14 new Number primitives (floor/ceiling/truncated/rounded/sqrt/squared/raisedTo:/factorial/even/odd/gcd:/lcm:/isInteger/isFloat). Fraction with normalisation + arithmetic + comparisons + asFloat. 620/620 total.
