databasev2 3, task 2.
- wo_wal_open removes `<log>.compact` before reading anything. The only
way one exists is a crash before the rename, which means its records
were never authoritative
- deleted rather than ignored, deliberately: a file full of well-formed
records sitting beside the log is exactly what a future reader mistakes
for data
Test uses PLAUSIBLE content, not garbage — a byte copy of a real log —
because garbage would be rejected by the CRC anyway and would prove
nothing. It asserts the temp is present before the open, gone after, and
that the live log still replays to exactly what it said.
RED was an assertion failure (`access(tmp, F_OK) != 0` unmet), not a
compile error, so the test was proven to exercise the behaviour before the
behaviour existed.
Verified: just wovm-test — 36 suites 0 fail, test_wal 340 pass, cli_smoke OK.
