+The installer, PowerShell, and manual Claude registration fixes are now combined

+exemptions and PowerShell enforcement, plus Claude settings locking and installer
+ownership/checkpoint protections. Focused combined suites pass.

+Claude settings pathname checks detect observed parent swaps and concurrent
+edits; they are not a native filesystem isolation boundary. The residual race
+between a final check and rename remains a follow-up, not a race-free claim.
+Successful managed-file upgrades retain their existing replacement semantics.

 # ECC 2.2.1
 
-ECC 2.2.1 is the signed ECC 2.2 patch release. It keeps the published `v2.2.0`
-history immutable while shipping the reviewed release-surface hardening that
-landed after the original 2.2.0 tag.
+ECC 2.2.1 is a bug and security patch for ECC 2.2. It keeps the published
+`v2.2.0` history immutable. These notes describe the prepared patch; publication
+and signing evidence are tracked separately in the release checklist.
+
+## Security and data protection
+
+- GateGuard and governance capture recognize destructive PowerShell commands,
+  including the native PowerShell tool path. Dynamic command handling prevents
+  later variable assignments from concealing earlier unresolved invocations
+  ([#2961](https://github.com/affaan-m/ECC/pull/2961)).
+- Relative GateGuard exemption globs stay within the project root. Explicit
+  absolute exemptions remain supported
+  ([#2921](https://github.com/affaan-m/ECC/issues/2921)).
+- Installer writes reject collisions with untracked user-owned files. Failed
+  installs checkpoint only files they actually wrote, preserving the previous
+  ownership hashes of untouched managed files
+  ([#2964](https://github.com/affaan-m/ECC/issues/2964)).
+- Uninstall respects `ECC_DRY_RUN=1`, including legacy Codex paths, and rejects
+  invalid dry-run values instead of silently allowing deletion
+  ([#2952](https://github.com/affaan-m/ECC/issues/2952)).
+- Observer analysis retains observations on unsuccessful or unconfirmed
+  processing. Exit code zero alone no longer permits archival
+  ([#2971](https://github.com/affaan-m/ECC/pull/2971)).
+- The Yarn lockfile updates `toml` to 4.3.0, matching the npm lockfile and
+  removing the affected older resolution.
+
+## Hooks and installation
+
+- Manual Claude installs register ECC-owned hook entries in Claude settings.
+  Repair, consent changes, and uninstall reconcile those entries while
+  preserving unrelated settings. Atomic settings updates check directory
+  identity and retry detected concurrent edits
+  ([#2992](https://github.com/affaan-m/ECC/pull/2992)).
+- Direct hook entrypoints handle larger JSON payloads with bounded, UTF-8-safe
+  reads instead of silently truncating valid inputs. Existing production
+  wrapper limits remain unchanged
+  ([#2924](https://github.com/affaan-m/ECC/issues/2924)).
+- The Pi adapter selects an actual Node runtime instead of recursively
+  executing a compiled OMP host as Node
+  ([#2909](https://github.com/affaan-m/ECC/issues/2909)).
+- Installer listing and control-pane help avoid eager third-party dependency
+  loading. Features that require absent runtime packages report the missing
+  dependency explicitly
+  ([#2994](https://github.com/affaan-m/ECC/pull/2994)).
+- Autonomous harness setup documentation replaces nonexistent package names
+  and unsupported CLI flags with documented interfaces, and distinguishes
+  session scheduling from a durable external scheduler
+  ([#2957](https://github.com/affaan-m/ECC/issues/2957)).

+## Scope and limitations
+
+- Plugin dependency handling does not bundle or automatically install missing
+  modules. Database and schema-validation features require their declared
+  runtime dependencies.
+- Ownership protection covers untracked collisions and failed-install
