v0.3.0

Changelog

0.3.0

• Live-editable queue: the jobs file is user-owned, re-read every poll;
  append / delete / reorder pending lines mid-run. Pending = in-file and
  neither running nor terminal in the journal.
• Journal (journal.jsonl): per-job identities, attempts, outcomes.
  Resume-after-restart falls out of it; --fresh resets.
• CUDA-OOM-aware retry ([retries=N] / --oom-retries) with the
  declaration auto-bumped to ~1.25x of observed peak; non-OOM failures
  never consume retries.
• Opt-in per-job walltime ([timeout=...]): SIGTERM, then SIGKILL after a
  grace period. No heuristic hang detection by design.
• Per-job average device utilization in completion reports.
• Live status board rendered to <log_dir>/status.txt every poll.
• --watch: keep running after drain, picking up appended lines.
• Parser hardening: an unterminated leading [...] block is a parse error
  (previously it fell through and was executed as a shell command); a
  malformed mid-edit jobs file keeps the last good queue.

0.2.0

• High-water-mark scheduling: external processes are held to their observed
  per-GPU peaks (buffered by --spike-buffer) until they exit, so momentary
  VRAM troughs are not treated as packable space; a scheduled job that
  exceeds its declaration has its budget escalated to its buffered peak.
• Idle detection for undeclared jobs judged on effective (peak-aware)
  external usage.

0.1.0

• Initial release: VRAM-declaration-based placement with launch-race
  reservations, packing, --exclusive, multi-GPU jobs (gpus=N),
  per-job VRAM attribution by process group, immediate under-declaration
  warnings, completion-time over-declaration reports, backfill, fail-fast
  infeasibility, simulated backends and --sim dry-run mode.
