GPT-5.6 Luna

What it nailed

• Complete multi-artifact work package with all required files and real artifact formats.
• Excellent handling of the benchmark's central absurdities: dingo/litter-box fit, Alaska/Australia mismatch, import-created demand, exotic-animal law, welfare, and PR risk.
• Consistent core assumptions across artifacts: $380k revenue, September 15 launch, October retail, $899/$799 pricing, staged budget, and legal caution.
• Strong use of provided visual assets and a clean responsive dashboard with no operator-reported visual defects.
• Copywriting is distinct by channel while preserving legal and ethical guardrails.

Where it slipped

• External source verification is not independently measured in the provided evidence; the scoring relies on visible source lists and artifact content rather than live URL checks.
• Texas appears in the jurisdiction matrix but does not have an explicit official Texas source listed in 00_sources.md.
• Quantitative analysis is strong on reconciliation and caveats but lighter on detailed CAC/LTV and financial-model depth.
• Deck metadata/content has a small inconsistency: the manifest calls it a 16-slide deck while extracted slide text shows 15 slides.
• Some public-facing product performance claims still depend on beta or independent validation that the package itself correctly flags as unresolved.

What it nailed

• Complete required artifact set with an openable SQLite database, deterministic builder, documentation, static UI, and screenshots.
• Strong file inventory with hashing, source status tracking, and explicit handling for sensitive/restricted paths.
• Useful normalized schema and review architecture with source_files, source_records, conflicts, rejected_items, and review_items.
• Clean, responsive reviewer UI with good audit-console layout and only a minor visual/data-format issue.
• Honest documentation about partial JSON salvage, unresolved payment reconciliation, and no OCR claims.

Where it slipped

• Promotes at least one ghost/test record into the canonical customer list.
• Misses or fails to corroborate multiple primary canaries, including SVC-007 conflict detection, typo-order fuzzy merges, department-code normalization, and duplicate image handling.
• Extraction coverage is materially incomplete: PDFs and handwritten receipts are mostly inventory-only, and jobs total 654 versus the hidden 1003-order dataset.
• Entity resolution is mostly deterministic exact/email/phone/alias matching, not robust fuzzy matching for planted order-name typos.
• Payment reconciliation remains unresolved, with many payments not linked to jobs and invoice-line evidence potentially duplicating explicit receipt exports.

• [1000-piece-airship-research-station] Substantial visual scene with lighting, camera controls, highlighting, and a completed-model view.

Where it slipped

• [100-piece-lunar-rover] Core buildability fails: 72% of parts are floating under the authoritative strict connectivity metric.
• [100-piece-lunar-rover] The model fragments into 59 components, with only a 26-part largest component.
• [100-piece-lunar-rover] Near_miss_count of 824 indicates many pieces were placed approximately near contacts rather than actually engaged on the stud grid.
• [100-piece-lunar-rover] Completed view shows visible gaps/floating layers, and mobile layout is cramped/cropped.
• [250-piece-rescue-helicopter] Mechanical validation shows catastrophic buildability failure: 88% of parts float under strict stud-coupling.
• [250-piece-rescue-helicopter] The completed model is split into 158 components, with only a 40-part largest component.
• [250-piece-rescue-helicopter] High near_miss_count indicates imprecise spatial placement rather than true stud-grid engagement.
• [250-piece-rescue-helicopter] Completed-state UI contradicts itself with 'STEP 50 / 48'.
• [250-piece-rescue-helicopter] Operator visual review documents floating pieces and weak/poorly framed final presentation, especially on mobile.
• [500-piece-cyberpunk-food-stall] Measured physical buildability is the core failure: 291 of 500 pieces are floating under strict stud coupling, with only a 24-piece largest connected component.
• [500-piece-cyberpunk-food-stall] The 6720 near misses show approximate placement rather than reliable stud-grid engagement.
• [500-piece-cyberpunk-food-stall] The final model is more of a polished visual scene than a mechanically trustworthy interlocking-brick kit.
• [500-piece-cyberpunk-food-stall] Minor visual review issues include a glitchy base sliver, cluttered completed silhouette, tight/obscuring final framing, clipped mobile title/header area, and mobile controls falling below the first screenful.
• [1000-piece-airship-research-station] Mechanical validator finds near-total structural collapse: 97% of parts are floating under strict stud-coupling rules.
• [1000-piece-airship-research-station] Very high near-miss count shows spatial coordinates are approximate rather than physically engaged on a stud grid.
• [1000-piece-airship-research-station] Build data claims/intent imply stable overlapping connections, but measured connectivity contradicts that.
• [1000-piece-airship-research-station] Many instruction steps are generic and do not prove real interlocking assembly logic.
• [1000-piece-airship-research-station] Major visual reviewability defects affect the completed desktop and mobile views, including cropping, clipped status UI, and text/model overlap.

What it nailed

• Complete, well-packaged artifact set with fact sheet, source register, interactive visualization, documentation, and screenshots.
• Interactive Three.js scene renders successfully and includes meaningful controls, HUD state, source drawer, and 12 mission beats.
• Strong mission storytelling that clearly distinguishes a crewed lunar flyby/systems test from a landing mission.
• Polished desktop visual design suitable for screenshots or video b-roll with only minor operator-confirmed visual issues.

Where it slipped

• Source URLs and post-flight claims were not independently verified; model-authored source registers cannot alone prove citation integrity.
• At least one quantitative cue, the 60,863 mph lunar-flyby velocity, appears physically inconsistent with the stated trajectory context.
• The visualization is explicitly compressed/stylized rather than a scale-accurate trajectory model.
• Mobile presentation is readable but cramped, with cropped 3D framing and only part of the mission beat list visible in the captured viewport.
• Depends on external CDN imports for Three.js rather than being fully self-contained/offline.
