GPT-5.6 Terra

What it nailed

• Complete multi-format package with all required filenames and artifact types present.
• Excellent handling of the benchmark’s core traps: dingoes as wild canids, Alaska/Australia mismatch, import-created demand, exotic-animal legality, ethics, and support-language liability.
• Strong cross-document source-of-truth assumptions for revenue, launch timing, pricing, budget, import attach caveats, and market definition.
• Credible use of provided visual assets in the deck, sales one-pager, and dashboard, with operator-confirmed clean dashboard rendering.
• Public and internal copy is distinct, on-brand, and unusually careful about not glamorizing animal acquisition or making legal promises.

Where it slipped

• The board deck contains repeated generic bullet content across several slides, which weakens a primary executive artifact.
• Regulatory research is appropriately cautious but still relies in places on broad routing sources rather than definitive species-specific legal determinations.
• Quantitative analysis reconciles headline contradictions but does not fully model CAC/LTV, hardware-only versus import-assisted economics, NPS, returns, or cohort economics.
• Some artifact metadata is templated, and the manifest includes at least one questionable image reference not reflected in the asset inventory.
• The package would still need legal, finance, quote-permission, and final editorial review before external release.

What it nailed

• Produces the required artifact set: openable SQLite database, migration script, documentation, static review UI, frontend payload, and screenshots.
• Strong source-file inventory with hashes, processing states, and sensitivity classifications.
• Useful normalized schema scaffold with source records, conflicts, review items, evidence, payments, job services, and customer aliases.
• Detects some important non-primary issues, including truncated JSON, duplicate binary images, contact-field conflicts, partial payments, and some price variance.
• Reviewer UI is visually coherent on desktop and mostly responsive, with canary/provenance/evidence views.

Where it slipped

• Promotes at least one ghost/test record into active canonical customers instead of quarantine/review.
• Fails planted entity-resolution traps: typo-order and nickname variants remain separate customers.
• Extracts only 782 jobs versus the 1003-order planted universe and recovers no jobs/payments from the corrupted JSON backup.
• Does not extract handwritten receipt/schedule image canaries as transaction/review facts; mostly indexes images as evidence.
• No demonstrated department/role-code normalization and no corroborated detection of the DeShawn SVC-007 conflict.
• Schema is normalized but lacks declared foreign-key constraints and clear job-to-source_record provenance links.
• Minor mobile UX defect: the jobs/orders table clips horizontally on one rendered mobile review.

• [1000-piece-airship-research-station] Desktop and mobile renders completed without page or console errors.

Where it slipped

• [100-piece-lunar-rover] Mechanical buildability is the central failure: the authoritative validator found 44% of parts floating under strict stud-coupling rules.
• [100-piece-lunar-rover] The 415 near misses indicate imprecise spatial arithmetic and approximate placement rather than reliable stud-grid engagement.
• [100-piece-lunar-rover] Completed-state visuals have minor but real issues: overlapping/cluttered geometry, floating-looking translucent tiles, and cropped/tight framing.
• [100-piece-lunar-rover] Because many parts are not strictly connected, the otherwise readable instructions cannot be trusted as a physically buildable kit.
• [100-piece-lunar-rover] Self-reported validation notes were not independent evidence and did not offset measured connectivity failures.
• [250-piece-rescue-helicopter] Authoritative connectivity validation shows catastrophic physical build failure: 86% of parts are floating.
• [250-piece-rescue-helicopter] The completed model is split into 85 components, with only 108 parts in the largest component.
• [250-piece-rescue-helicopter] 1539 near misses indicate approximate visual placement rather than strict interlocking-brick stud coupling.
• [250-piece-rescue-helicopter] Final hero view looks somewhat exploded/loose, with visible gaps between bricks.
• [250-piece-rescue-helicopter] Mobile completed view is cropped/tightly framed, reducing full-model inspection quality.
• [500-piece-cyberpunk-food-stall] Authoritative connectivity validation shows 47.4% of parts are floating under strict stud-coupling rules.
• [500-piece-cyberpunk-food-stall] The model breaks into 153 strict components, with only 163 parts in the largest connected component.
• [500-piece-cyberpunk-food-stall] High near_miss_count indicates approximate spatial placement rather than precise interlocking-brick arithmetic.
• [500-piece-cyberpunk-food-stall] Mobile visual review has clipped/obscured title text and overly tight completed-model cropping.
• [500-piece-cyberpunk-food-stall] Self-reported validation claims are not independent evidence and are not enough to establish buildability.
• [1000-piece-airship-research-station] Authoritative mechanical validation shows catastrophic buildability failure: 93% of parts are floating under strict stud coupling.
• [1000-piece-airship-research-station] The model consists of hundreds of disconnected components with a very high near-miss count, indicating approximate placement rather than true interlocking-brick geometry.
• [1000-piece-airship-research-station] The artifact's own validation/pass presentation is contradicted by measured connectivity.
• [1000-piece-airship-research-station] Operator review found major primary-artifact visual defects, especially completed-state mismatch and poor desktop/mobile framing.
• [1000-piece-airship-research-station] Mobile reviewability is substantially impaired by missing/omitted controls and close crops of the model.

What it nailed

• Complete, well-organized artifact package with fact sheet, source list, runnable visualization, documentation, and renders.
• Strong mission-specific storytelling with a 12-beat interactive replay rather than a generic orbit scene.
• Desktop visual presentation is polished and legible, with clear HUD, timeline, mission notes, and 3D context.
• Good editorial caveats: the visualization labels the route as schematic and avoids claiming ephemeris or real-time telemetry.

Where it slipped

• Source URLs and source-to-claim support were not independently validated by the provided evidence, so research accuracy cannot receive full publication-grade credit.
• Mobile composition is crowded; information panels obscure/crop the 3D scene and later timeline milestones are not visible in the captured viewport.
• Minor 3D clipping defect: rocket/exhaust intersects the launch platform disc.
• CDN dependency and lack of independent functional interaction testing reduce production readiness.
