+# Debug Surfaces External Integration
+
+## Audience
+Engine consumers, sample/game maintainers, and tool integrators that need to adopt the debug platform safely without coupling to internals.
+
+## Public Integration Path
+Use sample/game composition-level wiring only:
+1. Resolve debug flags/mode at entry (`dev|qa|prod`).
+2. Initialize debug integration only when debug is enabled.
+3. Pass integration into the scene layer as an optional dependency.
+4. Invoke update/render hooks only when integration exists.
+5. Dispose integration on scene exit/teardown.
+
+Reference implementation:
+- `samples/Phase 12 - Demo Games/Demo 1205 - Multi-System Demo/main.js`
+- `samples/Phase 12 - Demo Games/Demo 1205 - Multi-System Demo/MultiSystemDemoScene.js`
+
+## Production-Safe Contract
+- Debug is opt-in.
+- `prod` defaults to disabled.
+- Runtime query override is explicit (`?debug=1`).
+- No debug integration object means no console/overlay update or render overhead.
+
+## Build/Config Flags
+Entry-level build/config flags:
+- `BUILD_DEBUG_MODE`
+- `BUILD_DEBUG_ENABLED`
+
+Runtime overrides:
+- `debug` query param (`0|1|true|false|on|off|yes|no`)
+- `debugMode` query param (`dev|qa|prod`)
+
+## Performance-Safe Overlay Rules
+- Overlay and console are not initialized when debug is disabled.
+- Scene update/render checks remain guarded by optional integration presence.
+- Debug surfaces render last only when enabled.
+
+## Boundaries
+- No engine-core mutation required for adoption.
+- No direct access to private runtime state from integration consumers.
+- Track G (network) and Track H (3D) extensions are intentionally outside this contract.

-Executed PLAN + BUILD + APPLY for PERFORMANCE_BENCHMARKS in one scoped bundle.
+Executed PLAN + BUILD + APPLY for BIG_PICTURE_REMAINDER_COMPLETION.
 
-Implemented:
-- Added shared benchmark suite contract runtime in `tools/shared/performanceBenchmarks.js`.
-- Added automated benchmark suite coverage in `tests/tools/PerformanceBenchmarks.test.mjs`.
-- Wired benchmark test into `tests/run-tests.mjs`.
-- Updated performance benchmark PR docs and engine maturity performance rules.
-- Updated Track J roadmap bracket state for Performance benchmarks.
+Completed in-scope roadmap closure:
+- Track E reconciliation: BUILD_PR_DEBUG_SURFACES_ADVANCED_UX -> [x]
+- Track F completion:
+  - Sample game uses full debug platform -> [x]
+  - Toggle debug in production-safe mode -> [x]
+  - Performance-safe overlays -> [x]
+  - Build-time debug flags -> [x]
+- Track J completion:
+  - External documentation -> [x]
 
-Scope controls preserved:
-- No engine core API changes.
-- No destructive changes.
-- No unrelated runtime feature expansion.
+Implementation highlights:
+- Added production-safe debug gating and build/runtime debug flags in Demo 1205 sample entry.
+- Kept debug integration optional so overlays/console are off-cost when disabled.
+- Added external integration guide and linked it from architecture and docs indexes.
+- Applied roadmap bracket-only edits with no wording changes.
+
+Out of scope preserved:
+- Track G unchanged
+- Track H unchanged
+- No engine core API changes

+# BUILD_PR_BIG_PICTURE_REMAINDER_COMPLETION
+
+## Purpose
+Build and implement closure for remaining achievable roadmap work outside Track G/H, with docs-first and surgical scope control.
+
+## Workflow
+PLAN_PR -> BUILD_PR -> APPLY_PR
+
+## Implemented Build Scope
+
+### Track E Reconciliation
+- Confirmed roadmap mismatch existed (`BUILD_PR_DEBUG_SURFACES_ADVANCED_UX` was `[.]` while APPLY was `[x]`).
+- Reconciled status to complete through bracket-only roadmap update in APPLY.
+
+### Track F Game Integration Completion
+- Updated sample integration reference path only:
+  - `samples/Phase 12 - Demo Games/Demo 1205 - Multi-System Demo/main.js`
+  - `samples/Phase 12 - Demo Games/Demo 1205 - Multi-System Demo/MultiSystemDemoScene.js`
+  - `samples/Phase 12 - Demo Games/Demo 1205 - Multi-System Demo/index.html`
+
+Implemented contract outcomes:
+1. Full debug platform sample wiring remains active when enabled.
+2. Production-safe toggle is explicit (`prod` defaults safe/off unless forced).
+3. Overlay/render overhead remains performance-safe when debug is disabled (no integration object created).
+4. Build/config flags are explicit:
+   - `BUILD_DEBUG_MODE`
+   - `BUILD_DEBUG_ENABLED`
+   - runtime overrides via `?debug=` and `?debugMode=`
+
+### Track J External Documentation Finalization
+- Added durable external integration guide:
+  - `docs/architecture/debug-surfaces-external-integration.md`
+- Wired discoverability via:
+  - `docs/architecture/README.md`
+  - `docs/README.md`
+  - `README.md`
+  - `docs/dev/ENGINE_MATURITY_DOCUMENTATION_MAP.md`
+
+## Guardrails Preserved
+- No Track G edits.
+- No Track H edits.
+- No engine core API changes.
+- No unrelated restructuring.
+- Roadmap wording untouched.
+
+## Apply Handoff
+APPLY should set only approved bracket states in Track E/F/J and package only this PR scope.

+# PLAN_PR_BIG_PICTURE_REMAINDER_COMPLETION
+
+## Goal
+Execute a single PLAN+BUILD+APPLY bundle that closes all remaining achievable roadmap items outside Track G and Track H.
+
+## Workflow
+PLAN_PR -> BUILD_PR -> APPLY_PR
+
+## In Scope
+- Track E reconciliation:
+  - `BUILD_PR_DEBUG_SURFACES_ADVANCED_UX` -> `[x]`
+- Track F completion:
+  - `Sample game uses full debug platform` -> `[x]`
+  - `Toggle debug in production-safe mode` -> `[x]`
+  - `Performance-safe overlays` -> `[x]`
+  - `Build-time debug flags` -> `[x]`
+- Track J completion:
+  - `External documentation` -> `[x]`
+
+## Out of Scope
+- Track G (network/multiplayer)
+- Track H (3D support)
+- Engine-core redesign
+- Unrelated repo restructuring
+
+## Implementation Plan
+1. Validate and reconcile Track E state mismatch via roadmap status alignment.
+2. Complete Track F in sample-level integration only:
+   - add explicit debug gating in `Demo 1205` sample entry
+   - ensure debug integration is optional and disabled-safe
+   - define build/config debug flags and runtime overrides
+3. Finalize Track J external docs with a stable architecture-level integration guide.
+4. Apply bracket-only roadmap status edits with no wording changes.
+5. Update docs/dev control files + reports and package final bundle.
+
+## Validation Plan
+- Syntax checks for touched sample JS files.
+- Verify sample debug gating path is deterministic and optional.
+- Verify external documentation references are wired in docs index/architecture map.
+- Verify roadmap edits are bracket-only and limited to Track E/F/J items.
