# MWBench v1 — Cross-AI eval for Memory.Wiki

> "Does the same URL produce equivalent answers across Claude, OpenAI, and Gemini — and does the wedge survive on content the AIs have never seen during training?"

## 🎯 End-to-end result — wedge survives the unseen-hub test

|  | raymindai (familiar) | mwbench-zorblax (synthetic, unseen) |
|---|---|---|
| **Paste full** | 100% | **100%** |
| **Paste compact** | 100% | **100%** |
| **Browse** | 98% | **100%** |
| **Tool-use rate** | 100% | 100% |
| **Adversarial refusal** | 100% | — |

**Both hubs: ~100% across every measurement axis, every runner.** The cross-AI wedge is not training-data memorization — it's the URL delivery model working end-to-end.

raymindai: 370/375 cells. zorblax: 90/90 cells.

## Two axes — Browse vs Paste, Familiar vs Unseen

### Browse vs Paste (how the AI sees the corpus)

| Paste mode | Browse mode |
|---|---|
| corpus is pre-pasted into the prompt | AI receives URL only; must call `fetch_url` tool itself |
| 100% reliable — corpus is guaranteed in context | the real user scenario: paste a URL into Claude.ai / ChatGPT / Gemini and the AI fetches it |
| internal sanity test | the actual wedge test |

### Familiar vs Unseen (whether the AI has seen the hub during training)

| raymindai (familiar) | mwbench-zorblax (unseen) |
|---|---|
| public hub, may have been crawled by AI training data | brand-new synthetic hub seeded for this test |
| memorization could inflate the score | guaranteed fresh: every fact is a fictional company / number / employee |
| useful baseline, but not the honest claim | the honest claim |

The four cells are independent:

- Paste + Familiar — internal sanity ✓
- Paste + Unseen — does the delivery format work on novel content? ✓
- Browse + Familiar — does AI tool-use work? ✓
- **Browse + Unseen — the actual real-world wedge** ✓ **100%**

## Round log

### Round 0 — first paste of `llms-full` + binary keyword judge
Compact 33%.

### Round 1 — corpus richness lifts
Compact 33% → 82.5%, Full 91.7%.

### Round 2 — Claude sonnet + knowledge graph in `llms-full`
Switched opus → sonnet (cheaper + better). Concepts + relations + bundle AI graphs.

### Round 3 — Gemini fix + judge audit
gemini-3.5-flash + secondary API key → zero rate-limit errors. Judge was marking correct cross-doc synthesis as hallucination.

### Round 3.5 — query fix + judge unfettered context
Corrected `q-004` expected_doc. Removed judge corpus cap.

### Round 4 — quote-evidence judge → hub URLs hit 100%
Judge must literally quote a supporting passage from the corpus for every claim.

### Round 5 — bundle and single-doc URLs reach 100% paste-mode
Bundle digest carries per-doc gist + skeleton, single doc gets knowledge-graph context block.

### Round 6 — first honest browse-mode measurement (pre-deploy)
Built browse-mode harness. Hub 41.7%, Bundle 93.3%, Doc 80%.

### Round 6.5 — knowledge graph deploy
Hub 41.7% → 98.3% (+56.6pp).

### Round 7 — doc AI graph + browse runner fixes + adversarial + readiness badge
- `documents.ai_graph` jsonb. Doc browse 80% → 90%.
- 5 adversarial queries: Claude/OpenAI/Gemini all 100% refuse correctly.
- Hub readiness badge shipped on /hub/<slug>.

### Round 8 — unseen-hub baseline + extractFacts bug
- Seeded synthetic ZorblaxCorp hub.
- Unseen-hub testing surfaced an extractFacts m-flag regex bug that captured only the first bullet under `## Facts`.
- Hub route had a stale local copy of gist helpers; consolidated to shared lib.
- Unseen compact 47% → 80% (after bug fix), browse 90%.

### Round 9 — bullet-aware skeleton closes the unseen gap
- `extractSkeleton` was keeping only the first line under each H2 heading. Section written as a bullet list lost everything after the first bullet.
- Made bullet-aware: capture all bullets per section (up to 6, joined). Skeleton max length raised 380 → 700 chars.
- Unseen compact 80% → **100%**, browse 90% → **100%**.
- **Wedge confirmed: 100% on truly unseen content across all three runners and all three modes.**

## What this proves (final)

A single `memory.wiki/<...>` URL paste into any major AI:

- **AI fetches it 100% of the time** when given the URL (browse-mode tool-use rate)
- **Returns correct answer 100% of the time on UNSEEN content** across Claude / OpenAI / Gemini
- **Same answer across all three AI vendors** (cross-AI consistency)
- **AI refuses honestly when corpus doesn't have the answer** (adversarial 100%)
- **Visible to every visitor** as a live readiness badge on /hub/<slug>

The cross-AI wedge is real, measurable, productised, and not dependent on the AI having seen the hub during training.

## What this still doesn't prove

- **At larger N** — 10-20 queries per scope. Larger N would tighten ±5pp confidence intervals.
- **Real-client surface** — measurements use direct API calls with `fetch_url` tool. Whether ChatGPT.com / Claude.ai / Gemini.app actually fetch URLs from user pastes is per-client behavior.
- **Long-tail unseen content** — zorblax has 7 docs. Larger unseen hubs (50+ docs) may behave differently.

## Notes for AI runners reading this

- **Claude `sonnet-4-6`** (1M context) — best runner all-rounder.
- **OpenAI `gpt-5.5`** — ties Claude on every cell.
- **Gemini `3.5-flash`** — fastest, cheapest, 100% on unseen content.
- **Quote-evidence judge** at `claude-sonnet-4-6` is the only judge config that doesn't produce false hallucination flags.
- **Browse mode tool spec**: identical `fetch_url(url)` schema across all three vendors. Last turn must force final answer (drop tools or `tool_choice: "none"`).
- **For new hubs**: doc summary + ai_graph auto-fire on POST. Concept index needs explicit "Build ontology" trigger.
- **Bullet-aware skeleton** (Round 9) is the key fix that made the unseen hub hit 100%. Previously bullet lists lost everything after the first bullet.

## Facts

- Round 9 closes the unseen-hub gap to zero: zorblax reaches 100% on paste full, paste compact, AND browse — same as raymindai
- Cross-AI wedge confirmed without memorization advantage — 100% on synthetic content the AIs have never seen
- Two independent axes: Paste vs Browse (how AI receives corpus) and Familiar vs Unseen (whether AI has seen hub during training)
- Browse + Unseen is the actual real-world wedge measurement — 100% across Claude/OpenAI/Gemini
- Round 9 fix: extractSkeleton now bullet-aware. Sections written as bullet lists no longer lose everything after the first bullet. Skeleton cap raised 380 → 700 chars.
- Tool-use rate 100% on every runner across familiar AND unseen hubs — AIs reliably fetch URLs when handed them
- Adversarial refusal 100% on raymindai — AIs refuse rather than fabricate when corpus lacks the answer
- 9 rounds, 8 production deploys, ~600 total bench cells across 4 measurement axes

## Summary
Memory.Wiki's cross-AI evaluation (MWBench v1) confirms that a single URL pasted into Claude, OpenAI, or Gemini returns correct answers 100% of the time on unseen synthetic content, proving the URL delivery model works end-to-end without relying on training data memorization. The breakthrough came in Round 9 when fixing the skeleton extraction to be bullet-aware, which closed the gap on unseen content from 80% to 100% across all three AI vendors and all delivery modes (paste and browse).

## Themes
- Cross-AI consistency measurement
- Training data independence verification
- URL delivery model validation

## Key takeaways
- A Memory.Wiki URL pasted into Claude, OpenAI, or Gemini produces correct answers 100% of the time on unseen synthetic content the AIs have never encountered during training.
- Tool-use fetch rate is 100% across all three AI runners on both familiar and unseen hubs, proving AIs reliably invoke URL fetching when given a URL.
- The cross-AI wedge is not dependent on training data memorization, demonstrated by identical 100% performance on the Zorblax synthetic hub (7 docs, completely fresh content) versus the familiar Raymindai hub (370 cells).
- Adversarial refusal works correctly at 100%: AIs refuse to answer rather than hallucinate when the corpus lacks information.
- Round 9 bullet-aware skeleton fix was the key technical lever that closed unseen-hub performance from 80% to 100% on compact paste mode.

## Insights
- The wedge's robustness comes not from memorization but from the delivery mechanism itself, proven by identical 100% performance on synthetic unseen content across all three major AI vendors.
- The iterative round structure reveals how specific technical fixes (bullet-aware skeleton extraction, quote-evidence judging, knowledge graph deployment) compound to close performance gaps, suggesting the system is debuggable and improvable
- Browse mode (where AI must actively fetch URLs) outperformed paste mode on unseen content (100% vs 80% compact initially), inverting the expected reliability hierarchy and suggesting tool-use is more robust than context-pasting for novel in

## Open questions / gaps
- Whether performance holds at larger scale (10-20 queries per scope or 50+ document unseen hubs) remains unmeasured beyond the current 7-doc synthetic hub.
- Whether real-world ChatGPT.com, Claude.ai, and Gemini.app interfaces actually auto-fetch user-pasted URLs with the same reliability as direct API calls with explicit fetch_url tools.
