+# M03-RND-INTERNAL-ACCESS-GATE-001 — Streamer internal access gate
+
+<!-- OPENWC_CLAIM:M03-RND-INTERNAL-ACCESS-GATE-001:sindo-main-codex:2026-07-18 -->
+
+## Ownership
+
+- Target: M03
+- Program: RND
+- Owner/Agent ID: sindo-main-codex
+- Branch: `work/sindo-main-codex/m03-streamer-internal-access-gate`
+- Lease expires UTC: 2026-07-18
+- Integrator: M03 milestone integrator
+
+## Outcome
+
+Add an automated repository boundary gate proving gameplay code and Godot
+`EditorPlugin` implementations do not access `StreamingWorldLoader` private
+queue, task, cache or tile-state fields.
+
+## Non-goals
+
+- Change renderer behavior, queues, jobs, cache formats or facade contracts.
+- Ban scene composition references to the loader script or facade adapter path.
+- Migrate renderer-only diagnostic probes that inspect internal readiness/terrain;
+  those require the later metrics/ground-query facade contract.
+- Mark M03 complete.
+
+## Paths
+
+- Exclusive: `src/tools/verify_renderer_internal_access.gd`, this claim
+- Shared/hotspots: `docs/modules/world-renderer.md`, `RENDER.md`,
+  `targets/03-renderer-facade.md`
+- Read-only scan scope: `src/gameplay/**/*.gd`, Godot `EditorPlugin` scripts under
+  `src/**/*.gd` and `addons/**/*.gd`, and the streamer field declarations
+
+## Contracts and data
+
+- Input: repository GDScript source and actual private streamer declarations
+- Output: deterministic pass/fail diagnostics with consumer path and symbol
+- Runtime, scene, cache, coordinate and asset contracts: unchanged
+
+## Dependencies
+
+- Requires: integrated facade and scheduler master `a023d76`
+- Blocks: safe service extraction and M03 dependency regression acceptance
+- External state: none
+
+## Verification
+
+- Commands: dedicated internal-access gate, facade regression, coordination,
+  documentation and diff gates
+- Fixtures: gameplay source discovery, EditorPlugin discovery and synthetic
+  forbidden symbol detection
+- Fidelity evidence: source-only enforcement; no runtime or visual code changes
+- Performance budget: one bounded repository source scan in a headless test process
+
+## Documentation deliverables
+
+- World-renderer boundary/verification/known-gap/source-map updates
+- Renderer implementation note documenting diagnostic-tool exception
+- No new module spec because this package adds a verifier to the existing renderer module
+
+## Simplicity and naming
+
+- Important name: `verify_renderer_internal_access.gd`
+- Simplest approach: derive forbidden fields from the current streamer instead
+  of maintaining a second hand-written queue list
+- Rejected complexity: language plugin, custom linter framework or runtime proxy
+- Unavoidable complexity: recursive source discovery distinguishes actual
+  `EditorPlugin` scripts from renderer/import addons
+
+## Status
+
+- State: active
+- Done: scope and exception boundary defined
+- Next: implement gate, prove current consumers clean and document enforcement
+- Blocked by:
