Add opt-in bounded OpenTelemetry diagnostics across host preparation, scoped files, repository checkpoints, transport phases, and native execution. Preserve context parentage and stream cleanup, and retain diagnostic batches without per-file log writes.
Build qualification packs through the canonical frozen provider stage so lockfile, interpreter, and compiled bytes match the sandbox image. Keep ignored untracked repository files out of durable checkpoints.
