Cracking the new grader: a round-by-round log

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.

✓ Verified from the live grader source — not guessed. We pulled 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.

The rounds

1 · AI-generated photos (the old 18.1 winner)
16.1V 8.5 / A 7.6
Why we tried this

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?

What we learned

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.

2 · The restaurant's own real photos
16.1V 6.9 / A 9.2
Why we tried this

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.

What we learned

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.

3 · Professional stock photos — Pexels, unscreened
16.0V 7.7 / A 8.3
Why we tried this

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.

What we learned

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.

16.3V 7.6 / A 8.7
Why we tried this

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.

What we learned

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.

5 · Curated photos + proper page structure
~16.5est. from sub-scores
Why we tried this

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.

What we learned

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.

6 · + tasteful software color-grade ★ BEST (stock path)
16.6V 7.8 / A 8.8
Why we tried this

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.

What we learned

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.

How we made it
Round 5 build + a consistent, mild Pillow grade (autocontrast, +6% saturation, +5% contrast, light unsharp) applied identically to all photos. Pure software, no AI, reversible.

New direction: the restaurant's own photos + enhancement pipeline

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.

7 · Restaurant's own Instagram photos + enhancement — first attempt
15.8V 7.6 / A 8.2
Why we tried this

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.

What we learned

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."

Photo craftAI imageryAI textReal photo

What went wrong
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.
8 · Source-fixed: brief-only photos + cv2 CLAHE ★ BEST (real-photo path)
16.2V 7.5 / A 8.7
Why we tried this

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.

What we learned

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.

9 · Pro enhancement: + color temperature warmth + editorial vignette + smart crops
16.0V 7.7 / A 8.3
Why we tried this

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.

What we learned

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.

What hurt the score
Color-temperature shift (R/B channel scaling) + vignette (gaussian dark-edge composite) left a processing fingerprint Hive detected. Mild Pillow grade in Round 6 (Unsplash path) didn't trip it because those photos started as professionally-lit shots — the grade was cosmetic. Here it was corrective, and the delta was larger.
10 · AI restage — real photo in, professionally restaged out
15.2V 7.0 / A 8.2
Why we tried this

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.

What we learned

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.

How we made it
Each Instagram food photo → OpenAI 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.
The verdict on AI restage
It's the worst of all real-photo approaches. It costs authenticity (real_photo 7) without gaining craft (still 7). The plain enhanced photos (Round 8) beat it by a full point. The restaging prompt is interesting for showing customers what their photos could look like with professional gear — but not for maximizing grader scores.
11 · Real logo + visual QA loop gate + larger nav ★ BEST (real-photo path)
16.3V 7.5 / A 8.8
Why we tried this

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.

What we learned

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.

The bottom line

Three paths, one ceiling. After 11 rounds: curated Unsplash (16.6), real Instagram + enhancement + real logo (16.3), and AI restage (15.2). The two real contenders are within 0.3 of each other. The gap is craft (7 vs 8) and logo presentation (5 in both) — neither fixable in software.

The one unlocking input: a modest photo shoot of this restaurant — even the owner with a decent phone, the oven lit, a few pies on the counter. That simultaneously flips craft → 9, real_photo → 10, ai_imagery → 10. Every round has confirmed this is the single thing no pipeline can fake.
