v0.7.0rc2

Release candidate 2 of v0.7.0

Stabilization over v0.7.0rc1 (19 squash-merged PRs). No breaking API changes. src/ suite: 757 passed, CI green on Python 3.10/3.13.

Oversub benchmark driver (new feature)

• #143 oversub-bench driver + run_summary.json contract (kernel emits raw facts, driver computes validity)
• #147 default output_root under results/
• #148 per-trajectory timing breakdown (12 components) in trajectory-detail.csv
• #149 round_count pass-through + run-to-completion validity (fixes the multi-day never-finishing run)
• #150 flush partial oversub artifacts on interrupt

Replay observability hardening

• #151 / #153 vm_monitor Excel row-overflow guards (Raw_VM_Data + all per-sample timeline sheets)
• #152 guard happy-path trajectory export so a step failure cannot crash the run
• #154 render-OOM root-cause fix: _segment rejects a<=0 (a failed steps zeroed pause_end no longer produces a ~1.8e9-second segment → OOM/hang); plus Gantt/per-step downsampling and a 6h trial_timeout_sec backstop; wait-decomposition refactor + docs
• #157 reap vm_monitor on process exit, not xlsx appearance
• #159 wait-decomposition all-zero bug root-cause fix: attribute the slept think-delay to natural_delay; drop the redundant +delay term in interaction_total (value-preserving: interaction_total stays 568)

CI / tooling / docs

• #139 English bench-core usage guide
• #140 version-independent snapshot_size stub + Python 3.10/3.13 CI matrix
• #142 bump ruff/mypy target to py310 + pyupgrade auto-fix
• #144 remove obsolete fix_scripts
• #145 rename vm_monitor/replay excel outputs
• #146 remove orphaned add_l3_hit_rate_to_excel
• #141 document squash-merge multi-commit PR rule in CLAUDE.md
