## Authoritative User Request
MANDATORY: Read the authoritative user request at:
c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md (specifically section ## 2026-10-01T19:19:13Z - R4).
Also read c:\Projects\FreeExile\GEMINI.md, c:\Projects\FreeExile\AGENTS.md, and c:\Projects\FreeExile\.agents\teamwork\worker_m4_1\handoff.md.

## Minimap & Render Stress Instructions
Empirically stress-test the Minimap HUD and visual renderer:
1. Minimap Aspect-Ratio & Centering: Verify non-square maps (60x45, 120x90, 80x80) maintain proportional aspect ratio without squishing or stretching on the 120x80 canvas.
2. Throttling & Offscreen Cache: Verify terrain does not re-bake during normal movement when fog is unchanged. Verify redraws cap at 30 Hz. Verify 0 updates occur when `window.isGamePaused = true`.
3. Landmark & Entity Suppression: Verify that undiscovered POIs, waypoints, and locked Boss Gates do not render markers on the minimap or sprites on the world canvas.
4. Non-Regression Verification:
   - `pytest tests/unit/test_fog_and_minimap.py -v`
   - `pytest tests/unit/test_tile_collision.py -v`
   - `node tools/perf/map_render_benchmark.js` (Must PASS with 0 stationary re-bakes)
   - `pytest tests/unit/ -q` (all unit tests must PASS)

Provide an explicit verdict: APPROVE or REQUEST_CHANGES in handoff.md and notify parent when complete.

You are challenger_m4_2 in the FreeExile development studio.

Working Directory: c:\Projects\FreeExile\.agents\teamwork\challenger_m4_2\
Original Request File: c:\Projects\FreeExile\.agents\teamwork\ORIGINAL_REQUEST.md (MUST read section `## 2026-10-02T02:00:04Z` before starting work).
Project Scope Document: c:\Projects\FreeExile\.agents\teamwork\orchestrator_14\PROJECT.md
QA Worker Handoff: c:\Projects\FreeExile\.agents\teamwork\worker_m4_qa\handoff.md

Your Mission:
Adversarially stress-test the test suites, memory limits, and engine invariants:
1. Run the entire pytest suite:
   `pytest tests/unit/test_map_styles_db.py tests/unit/test_map_styles_catalog_sync.py tests/unit/test_map_style_assets_integrity.py tests/e2e/test_30_biomes_generation_e2e.py tests/security_fuzzing/test_map_styles_adversarial.py tests/unit/test_map_styles_adversarial.py tests/unit/test_map_styles_adversarial_stress.py -v`
   Verify 100% pass (379/379).
2. Run Node.js unit and stress suites:
   `node tests/unit/test_biome_texture_manager.js`
   `node tests/security_fuzzing/test_challenger_biome_texture_stress.js`
   `node tests/security_fuzzing/test_challenger_lru_thrashing_stress.js`
   `node tests/security_fuzzing/test_challenger_tile_grid_stress.js`
3. Challenge memory invariants:
   - Prove that LRU chunk caching strictly bounds OffscreenCanvas instances to 8 slots.
   - Prove that total renderer memory does not exceed 16.5 MB under rapid zone and biome switching.
   - Verify that non-existent biome codes (e.g. 0, 31, 999) trigger graceful fallback without throwing unhandled exceptions.
4. Deliver your verdict (APPROVE or REJECT) in `c:\Projects\FreeExile\.agents\teamwork\challenger_m4_2\handoff.md`.
5. Notify orchestrator via `send_message`.
