 # APPLY_PR_LEVEL_12_6_REMOTE_DEPLOYMENT_CANDIDATE
 
 ## Apply Summary
-Minimal single-node remote deployment candidate was integrated for the authoritative server runtime path.
+Minimal single-node remote deployment candidate was validated with execution-backed host and LAN evidence.
 
 ## Validation Results
-- single-node remote compose service is defined
-- remote startup/shutdown instructions are documented
-- public endpoint probe path is documented
-- remote client session validation path is documented
+- Validation timestamp (UTC): `2026-04-15T14:17:50.094Z`
+- Host runtime checks passed:
+  - `health_loopback` -> HTTP 200 (`NETWORK_SAMPLE_A_DASHBOARD_HEALTHY`)
+  - `metrics_loopback_without_key_blocked` -> HTTP 403 (`ADMIN_KEY_REQUIRED`)
+  - `metrics_progression_over_time` -> pass (`txBytesTotal: 0 -> 892`, `rxBytesTotal: 0 -> 534`)
+  - `session_lifecycle_transitions` -> pass (observed `connected`, `connecting`, `synchronizing`, `disconnected`)
+- LAN-address checks passed (`192.168.2.58`):
+  - `remote_without_key_blocked` -> HTTP 403
+  - `remote_with_key_allowed` -> HTTP 200
+- Aggregate result: `6/6` checks passed (`allPassed: true`)
+- Docker daemon was unavailable in this environment (`dockerDesktopLinuxEngine` pipe not found), so containerized remote-host execution could not be performed in this run.
+
+## Testable Outcome
+This PR remains testable through deterministic execution:
+1. run `node --input-type=module -` validation script against `createNetworkSampleADashboardServer(...)`
+2. verify health and access-control responses
+3. verify telemetry progression over time
+4. verify connection-state lifecycle transitions
+5. verify non-loopback LAN access with admin-key gating
+
+## Roadmap Update Rule
+Update:
+`docs/dev/roadmaps/MASTER_ROADMAP_HIGH_LEVEL.md`
+
+Allowed:
+- status markers only: `[ ]` `[.]` `[x]`
+
+Forbidden:
+- wording edits
+- structure edits
+- additions
+- deletions
+
+## Expected Marker Progress
+- `promotion/readiness gate`: `[.]` -> `[x]` only if remote deployment validation is completed successfully and execution-backed evidence exists
 
 ## Status
-APPLY complete for remote deployment candidate scope (single-node only).
+APPLY validation evidence captured. `promotion/readiness gate` remains `[.]` in this run because internet-host container validation evidence is not yet available.
