Addresses the repository-controlled parts of #65.

• Generation reports expose structural validation, screenshot generation, visual review, and native review independently. A blocked preview provides a machine-readable action and the verified PPTX path. The runner retains the failed exit status and the preview error details.
• A nonretryable checkpoint requires explicit --retry-preview after host capability is confirmed. Changing browser or extraction settings alone cannot cause the runner to replay a blocked preview.
• Compact PPTX creation includes an executable image operation with a local file. The managed log analyzer distinguishes named probes from formal operation-file milestones.

The installed-package regression exercises native image insertion, a policy-denied preview with a wrapper-masked child exit, and resume with altered environment settings. Focused tests cover the operation milestone, generation recovery, and write receipts.

The public report has no final PPTX, raw events, or specified WorkBuddy environment. The full host cold/warm benchmark and host-wrapper lifecycle verification remain open. No end-to-end time reduction is inferred from these regressions.
