Two fixes from the wedge-hunt endgame: 1. Full-suite mode switches from one 'bun test --parallel' invocation to N concurrent shard PROCESSES, serial within each (the paid runner's proven model; N = min(6, cpus-2)). The single-invocation strategy hit three distinct Bun 1.3.13 worker pathologies in one day — a segfault whose crashed-worker retry wedged the run, a quarantined file's still-running file-level hooks stalling a worker, and spawn-heavy files hanging under load — and each one stalled the WHOLE invocation. Process shards isolate any wedge to its own shard. First full run under this model: no wedge, six epilogues, one real failure named. WORKER_HOSTILE stays as the paper trail; --parallel remains available per-shard for a future Bun. 2. That one real failure: spec-template-sync regenerates SKILL.md via a child that inherited the shard process's env — an earlier test's GSTACK_*/GBRAIN_* mutations changed generator output (failed in-suite, passed solo on an identical tree). The child now gets a scrubbed env: generator output must be a function of the templates, not of whichever test ran before. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
