Five named tiers (JUDGE 120s / CAPTURE 300s / CAPTURE_LONG 600s /
PTY 900s / PTY_LONG 1200s) replace hand-ratcheted sprawl (46x300s,
46x120s, 44x360s, 44x180s, 27x240s, 19x150s, 13x420s, 12x600s...),
much of it inflated to paper over the old 40-way in-shard concurrency
that the sharded runner's 1-file-per-shard model kills. Policy test
pins: every tier fits the shard wall minus 120s overhead (the
structural fix for budgets-above-the-wall fiction), tiers stay ordered,
and no paid literal exceeds PTY_LONG x1.25 — oversized tests get split,
not budgeted past the wall.
