+# Phase 1B installation registry evidence
+
+- Date: 2026-07-18
+- Requirement IDs: R-009, R-024, R-027
+- Phase/gate: phase 1 / durable installation identity registry
+- Scope: exact adapter-fingerprint matching, persistent UUID generation, move aliases,
+  XDG state resolution, bounded strict JSON, locking, atomic replacement, and backup
+- Exclusions: adapters, launch plans, configuration precedence, providers, CLI changes,
+  and process execution
+- Commands: `make verify`; `make audit`; human and JSON `kiln doctor` smoke paths
+- Expected result: identity survives reloads and moves; ambiguous, corrupted, oversized,
+  and unsafe state fails closed without mutation; concurrent resolution creates one entry
+- Observed result: 20 unit, contract, adversarial, persistence, and concurrency tests
+  passed; Rustfmt, workspace/all-target compilation, Clippy with warnings denied, and
+  cargo-deny advisories/bans/licenses/sources passed
+- Result: pass
