v1.3.22 — Investigation recovery boundaries

Investigation failures now stay tied to the selected question and checkpoint, preserving applicable completed evidence while distinguishing partial capability and precise blocked questions. Recovery follows REA’s existing rules; timeout and retryable flags do not establish absent functionality or justify unchanged retries, broader access, software acquisition or paid analysis fallbacks.

The fixed artifact-capture checker rejects contradictory raw failure/partial fields alongside matching streams and exits. Seven controlled process-failure regressions verify preservation of completed work and failed attempts without false completion.

The existing public CI matrix now verifies and tests the exact extracted release archive as well as source. No new runtime dependency, retry engine or service is introduced. Installer, updater, integration consent and read-only check behavior are unchanged.

Validation uses same-agent source review and bounded fixtures; it does not certify arbitrary prose, model compliance, whole-target equivalence or a universal cause of tool failures. Historical provider observations remain historical.
