Three changes to make `pnpm test` reliably minimal and fail gracefully:
- @fusion/core is now a memory-envelope/wide-fan-out package (was unguarded).
It's the hub nearly everything imports (~354 test files), so a core source
edit made `vitest --changed` expand to ~the whole core suite and blow past the
engine's 15-min verification kill -> SIGKILL + task restart. Adding it to
SCOPED_AFFECTED_MEMORY_ENVELOPES applies the wide-fan-out guard (run only
directly-changed core tests, else delegate) and the bounded env. core is NOT
gate-covered, so delegation warns loudly rather than false-greens.
- Lower CLASS_BUDGET_BANDS.changed ceiling 20min -> 13min so the script watchdog
fails a runaway local lane itself (exit 124, no restart) BEFORE the engine's
15-min kill restarts the whole task. A tightening, not a timeout-widening.
Guard test pins ceiling < 900_000ms.
- Raise scoped-affected worker fan-out 1 -> 4 (operator decision). Was 1 only
for OOM safety (FN-6854/FN-6874); the fan-out guard now bounds the set so the
hundreds-of-files OOM driver no longer reaches these workers. Heap stays
6144MB/worker (~4x6GB on the lane) — revisit if a RAM-constrained CI runner
OOMs. Trades FN-5048 worker-knob guidance for throughput, scoped to the
bounded affected lanes only.
Tests: test-changed 117/117, watchdog 15/15, eslint clean.
