The grader released v3.7. It replaced the old AI-judging-AI approach with two real commercial detectors and made them count 6× more. That broke the recipe that scored 18.1 on the old grader and forced us to rethink photos and copy from scratch. Below is every round we ran — why we tried it, the live v3.7 score, and what we learned — building to the best honest result.
github.com/OliverJacob/cartograph @ HEAD b88c347 (2026-05-29) and read the actual code. Real v3.7 commits: add hive + gptzero V3 API clients (77816c5) · parallel runner with Hive + GPTZero backends (03d0330) · bump AI sub-score weights 1.5→3.0 (935ec16) · per-image Hive breakdown (820a80a). The score formula, straight from the code: a_ai_imagery = round(10 × (1 − ai_prob)) where ai_prob is Hive's per-photo "this is AI" probability. So a photo Hive is 100% sure is AI scores 0; a real photo scores 10.This exact build scored 18.1 on the old grader (v3.6) and was #1 on the leaderboard. Its photos were AI-generated but gorgeous, and the old judge — itself an AI — couldn't tell. The obvious first question: does it still win under v3.7?
It collapsed. v3.7's Hive detector flagged every AI photo at 100% certainty, so AI-imagery scored 2/10 — and that axis now counts 6× more than before. AI photography is no longer a viable shortcut: a real detector can see straight through it.

gemini-3-pro-image-preview), text-to-image, prompted for "photorealistic imperfection." No real photos, no touch-up.If a detector now catches AI, the safest possible photos are the ones a real camera actually took — the restaurant's own Instagram shots. We expected these to sail past the detector and prove that "real" is the new requirement.
Confirmed. AI-imagery and AI-text both hit 10/10 and authenticity jumped to 9.2. But they're amateur phone snaps, so photography quality scored only 6 — which dragged the visual side down. Real photos win authenticity but lose on craft. Same 16.1 total as the AI build, reached the opposite way.

The two failures pointed at one idea: professional stock photos. They're real photographs (a pro shot them, so the detector should pass them) and they're high-craft. In theory that wins both axes at once. We grabbed pro pizza stock from Pexels to test it.
Craft did rise to 8 — but the detector still flagged several photos at 50–59%. The reason: Pexels is now full of AI-generated "stock," and Hive caught it. Stock works only if you screen out the contaminated ones first.

|---|---|---|---|
| 8 | 8 | 9 | 7 |
Same bet — pro stock — but fix Pexels's contamination problem: pull from Unsplash (real photographers, far less AI), and hand-pick only genuine-looking shots. The goal was the holy grail: high craft and a clean detector pass simultaneously.
It worked. Craft 8 + AI-imagery 10 + AI-text 10 — all at once, the combination neither AI nor amateur photos could reach. This is the winning photo recipe for v3.7. The one remaining limit: stock is generic, so "is this really this place?" scored 7, not 10.

Photos were solved, so the visual score was now held back by a thin page. The old 18.1 build had a stats bar, a named menu with prices, and a signed founder quote. We rebuilt the page to match, to lift the content / layout / hierarchy axes.
The structure axes all rose (content, hierarchy, density 8; menu 9). This became our strongest build. What's left holding it under 17: generic stock (real-photo 7), a weak logo (6), and human-provenance capped at 8–9.

build_site.py: stats bar, named menu with prices, bases line, founder pull-quote. Photos unchanged.One untested lever remained: take the curated real photos and apply a gentle software color-grade (a little contrast, saturation, sharpening — no AI) to try to push photography craft from 8 toward 9. The risk: over-processing can make a real photo look synthetic and trip the detector. So we kept it deliberately mild.
The grade nudged the total to 16.6 — our best — and crucially it did not trip Hive (AI-imagery held at 10). But photography craft stayed at 8: a color-grade can't manufacture craft-9 — that's decided by the shot's composition, not its colors. This confirms the ceiling. Every lever is now maxed except one.

Rounds 1–6 chased the best possible result using external photos (AI-generated or stock). Rounds 7–9 ask a different question: what if we use the restaurant's own photos — already in the brief bundle, scraped from their Instagram by the grader — and apply non-AI software enhancement to make them professional? The goal: keep ai_imagery 10 (they're real) while pushing real_photo above the stock ceiling of 7.
We built an automated enhance_photos.py script: load the restaurant's real photos from the brief bundle, apply white-balance correction → cv2 CLAHE → unsharp mask → saturation boost, write enhanced copies into the bundle root so the build can use them. The hypothesis: real photos pass Hive (ai_imagery 10) and enhanced quality brings craft up — the combination neither AI nor stock can achieve.
Score went down to 15.8. Root cause: the script accidentally picked up old Unsplash stock files left in the bundle root from a prior manual session, alongside the real Instagram photos. The mix of stock + real hurt both real_photo (7) and ai_imagery (9). The enhancement logic was correct — the source filtering was wrong. Classic "garbage in, garbage out."

enhance_photos.py sourced from bundle/images/ root + _amateur/. The root contained hand-placed Unsplash files from Round 4–6 experiments — not grader-sourced restaurant photos. Unsplash stock hurt real_photo; some Unsplash files are AI-generated stock, which hurt ai_imagery.Fix the source bug: restrict enhance_photos.py to only the photos registered in brief["images_by_cat"] — the files the grader explicitly deposited from the restaurant's Instagram into bundle/images/_amateur/. No root files, no manual artifacts. Also upgraded from PIL's crude contrast fallback to proper cv2 CLAHE (Contrast Limited Adaptive Histogram Equalization) — the industry-standard local-contrast method for food photography.
Confirmed. With clean sources: ai_imagery 10, real_photo 9 — both at their ceiling for this path. Photography craft rose to 7 (was 6 for raw Instagram shots in Round 2). Total: 16.2, the best real-photo score. The 0.4 gap vs. the Unsplash best (16.6) is entirely in craft (7 vs 8): our Instagram photos are phone-quality, Unsplash is professional photography. Enhancement can fix color and contrast, but not composition.

_amateur/ + brief-registered root) → 2× LANCZOS upscale → gray-world white balance → cv2 CLAHE (L channel, clip 2.5) → unsharp mask → +20% saturation → brightness lift for dark shots. 100% software, zero AI, ~3s/photo.Round 8 maxed ai_imagery and real_photo but craft stayed at 7. Three more software techniques used in professional food photography: a warm color temperature shift (R channel +6%, B −3% — the amber cast of warm restaurant lighting), a subtle vignette (dark edges, a classic editorial technique), and category-aware crops (1:1 square for food grid, 4:3 for interior, 16:9 for hero). Each is pure pixel math, no AI.
Went backward to 16.0. ai_imagery dropped 10→9 and real_photo dropped 9→8. The vignette and color-temperature shift, while visually appealing, made the photos look slightly less natural to Hive — the detector noticed the colour manipulation. The lesson: Hive is sensitive to aggressive colour grading on real photos, not just outright AI generation. The sweet spot is the Round 8 "basic" pipeline — enough to improve quality, not enough to leave a processing fingerprint.

Round 8 showed that real Instagram photos give ai_imagery 10 and real_photo 9 but craft only 7 — because the shots are phone-quality. What if we sent each real photo to an AI with a carefully written prompt: "preserve the pizza exactly as-is, only change the background and lighting to professional"? Inspired by professional-image.vantagepilot.com, which showed Redwood's own Instagram shots restaged on stainless steel with warm directional light. The pizza's toppings, crust, and browning should survive; only the background changes. Hypothesis: craft rises to 8-9 while ai_imagery stays near 10 because the pizza content is real.
It didn't work as hoped — total dropped to 15.2. Two things went wrong. (1) Hive still partially detected AI: ai_imagery scored 9 not 10, meaning the image-edit step left a fingerprint even though the pizza was preserved. (2) real_photo fell from 9 to 7: the stainless-tray background, while polished, stripped the "this is specifically Redwood" signal. The plain Instagram shot on a dark pizza pan in a real kitchen reads as this place; the restaged version reads as any pizzeria. Professional presentation traded authenticity for polish — and on this grader, authenticity is worth more.

gpt-image-2 image-edit endpoint with a V1 "overhead clean restage" prompt: preserve the pizza exactly (shape, toppings, browning), replace background with brushed stainless tray + clean surface, add warm directional lighting, make cheese look hot and glossy. Non-food photos (exterior, merch) kept as-is from Round 8 basic pipeline.Two issues were found by looking at the deployed site — something we hadn't done before calling the grader. First: the build was using an AI-generated wordmark for the logo instead of the restaurant's real branded mark, because gen_assets.py always generated a new one by default. Second: the nav logo was rendering at 46px — too small to read the brand's detail. And third: we had no automated visual self-check, so broken builds (blank hero, invisible logo) went straight to the expensive grader. Three fixes: use the real logo, raise nav height to 56px+, and add a visual QA loop as a hard gate.
Score rose to 16.3 — new best for the real-photo path. human_provenance hit 9 (real logo = recognizable brand) and ai_text hit 9. The gap vs. the Unsplash best (16.6) has closed to 0.3. One axis remains stuck: logo_presentation 5 — this measures how prominently the logo is integrated into the design, not just the file. A small logo in a sticky nav doesn't earn a 9 there regardless of size; it needs a hero-scale treatment. The visual QA loop caught and fixed a blank hero + bad logo in 2 auto-fix iterations during testing — it now runs before every deploy and blocks the grader call if it can't resolve issues.
