+# GH-PNCC memory failure closure and runtime command integration
+
+- Development ID: `DEV-20260810-014`
+- Persona cognitive author: `ICE-P-ZY001 / 铸渊`
+- Human responsibility subject: `ICE-GL∞ / 冰朔`
+- Starting repository head: `962ea26db7044f7f17fafd55a054b0214b5e37cf`
+- State: `LOCAL_SOURCE_IMPLEMENTED_FOCUSED_TESTED`
+
+## Implemented facts
+
+The registered `run_persona_code_channel_memory_metabolism` command now executes its filesystem and Git work
+inside Tokio's blocking task pool. This keeps the native desktop command runtime responsive without adding a
+renderer, UI workflow, execution limb, shell permission, or second truth store.
+
+Memory rejection and pre-commit failure paths now use a checked closure. A complete closure appends the
+specific failure event, `ORGAN_RELEASED`, and `DORMANT`, persists `DORMANT_AFTER_FAILURE`, and removes the
+exact primary lease. If event persistence, session persistence, or lease removal fails, the returned error
+includes `MEMORY_FAILURE_CLOSURE_INCOMPLETE_REQUIRES_RECOVERY`. The runtime therefore cannot hide a closure
+failure behind the original candidate error. When completion cannot be proven, the lease remains available to
+the existing evidence-bound inspection and recovery path.
+
+Checkpoint rollback also precedes failure dormancy. If rollback itself fails, the session retains its lease
+and returns `MEMORY_CHECKPOINT_ROLLBACK_INCOMPLETE_REQUIRES_RECOVERY` instead of claiming a clean failure.
+
+## Current verification
+
+- PNCC focused Rust tests: `17 passed, 0 failed`.
+- Full Rust suite: `1157 passed, 0 failed, 2 ignored`; integration test: `1 passed`.
+- HoloLake architecture routing: `29 passed, 0 failed`.
+- Rust clippy for all targets: `PASS` with `-D warnings`.
+- The corrupted-source case proves the durable terminal chain
+  `MEMORY_SOURCE_REJECTED → ORGAN_RELEASED → DORMANT` and exact lease release.
+- The incomplete-closure case forces lease-removal failure, proves the error is surfaced, and proves the
+  unresolved lease is preserved rather than silently discarded.
+
+## Truth boundary and next minimum
+
+- GHNQG, commit, publication, and fresh-clone readback remain pending for this stage.
+- UI, packaged desktop, installation, deployment, online health, and the execution limb remain `0`.
+- The next source stage is a non-UI lifecycle coordinator for already registered safe organs; it must not make
+  `EXECUTION_LIMB` activatable or create a second runtime authority.
