Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass Submission 🌿

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass

Apparently, asking a 2B model for evidence was like asking a guy in a group chat for sources.

I showed a small AI on my laptop two photos from a walk and asked how they were connected. It almost always had an answer. In 6 of my 10 test pairs, it invented the answer.

So I changed the rules of my game: the AI can help you notice things, but it doesn't get to decide what's true.

What I Built

UNSEEN is a walking game. You start an expedition, put your phone away, walk, and come back with a photo of something you noticed. A local open-weight vision model describes what you see. Game rules, not the model, decide whether it counts. If it does, it earns materials for your virtual world.

  1. Walk. Choose a duration and put the phone away.
  2. Notice. Find one real thing worth a photo.
  3. Return. The local model describes it.
  4. Discover. An evidence gate accepts or rejects it, and tells you why.

It's for people who like games but want a reason to look up. On my test walk, I spent 25 minutes outside and 2 minutes on the screen.

1. The Story β€” Why UNSEEN Exists

Most digital games are closed loops. They reward you for sitting still, clicking faster, watching screens, and grinding synthetic numbers designed to keep your attention trapped inside an artificial box.

UNSEEN was built on an opposite conviction: the most intricate, surprising, and grounding world ever made is the physical environment…

How I Built It

Before building, I wrote a test and its pass bar: 10 photo pairs (6 related, 4 unrelated), run once through a small local model.

The confidence was there. The receipts were not.

Check Needed Result
Good outputs 6 / 10 2 / 10
Unrelated pairs answered "no relationship" 6 / 7 1 / 7
Invented details stated as fact at most 1 6 / 10
Median latency under 30 s 20.7 s (range 15.7-49.6 s)

The model failed my pass bar. Not a little. It had confidence, creativity, and absolutely no business handing out rewards. The latency numbers are not a clean benchmark because my laptop was swapping heavily.

So the model no longer judges anything. It only describes the photo as structured data, and plain code decides:

The evidence gate is deliberately boring; that's the point. It checks whether the observation contains the required evidence, whether the result is eligible, and whether that observation has already been claimed. It rejects ineligible or duplicate claims instead of letting the model award materials based on a plausible story. The model describes; deterministic code decides.

Stack: Qwen3-VL-2B-Instruct (Q4_K_M) through Ollama, built with Antigravity.

Why Does Open Innovation Matter?

I could run the experiment myself. I could feed the model unrelated photos on purpose, read what it said, measure it, and redesign around the failures. With a hosted API, I would have had a black box and a bill.

Inference here runs locally through Ollama, so photos aren't sent to a hosted AI service, and each photo costs nothing. A stronger hosted model might have judged relationships better, and this small one was slow on my hardware. Open-weight AI made the experiment possible. Careful engineering made the result trustworthy.

My Agent Session

Bro saw two photos and made up lore. This session shows how I traced UNSEEN's zero-reward bug to the evidence gate, fixed the classification logic, and verified the fix against live local inference.

UNSEEN β€” Diagnose Why Every Outdoor Photo Gets 0 DM

The player has tested multiple images, including a new outdoor photograph, but the submission popup still shows:

  • Field Study Record
  • 0 DM
  • Physical exploration unlocks living items

The Sanctuary inventory remains empty.

Our intended gameplay is simple: upload a photograph β†’ receive a discovery and earned rewards β†’ see those rewards in Your Sanctuary. Technical details should stay behind the scenes.

Phase 1 β€” Find the exact cause

Trace the real submission flow through the existing code:

  1. Photo upload and image data passed to local Qwen3-VL through Ollama.
  2. Model response and its parsed output.
  3. Image eligibility classification.
  4. Candidate discovery generation and confirmation.
  5. Reward calculation and claiming.
  6. Persistent inventory update.
  7. Sanctuary inventory rendering and reward popup.

Inspect the exact conditions that produce the "Field Study Record" popup and 0 DM. Determine whether this is an intentional eligibility decision, a classification bug, a missing confirmation step, a failed reward claim, or a state synchronization problem.

Check whether the submitted image's actual eligibility result is preserved through every stage. Do not infer the cause from the popup text.

Phase 2 β€” Reproduce the problem

Use the existing test infrastructure and inspect the real application state. Test:

  • A new outdoor photograph.
  • A screenshot or synthetic/3D-rendered image.
  • A genuine outdoor observation that has already been rewarded.

Inspect the browser console and relevant runtime logs. Do not run unnecessary repeated model inference if existing results are sufficient.

Phase 3 β€” Fix the root cause

Make the smallest targeted fix once the cause is established.

  • A genuinely eligible, unclaimed outdoor observation must be able to earn its configured rewards.
  • Ensure the required confirmation step is actually available and understandable to the player.
  • Save earned materials to persistent state and display them in the Sanctuary.
  • Prevent duplicate rewards for previously claimed observations.
  • Keep digital renderings and synthetic test images ineligible for physical rewards.
  • Do not treat an image as ineligible merely because it is old.
  • Do not award rewards when analysis fails or evidence is insufficient.
  • Do not weaken the existing evidence safeguards just to make the test pass.

Do not redesign the UI, change the core game loop, or introduce new systems.

Phase 4 β€” Verify the complete gameplay loop

Verify the following end to end:

  1. Upload a genuinely eligible outdoor photo.
  2. Receive a clear, enjoyable discovery result.
  3. See the actual earned reward in the result popup.
  4. Open Your Sanctuary and find the earned item in the inventory.
  5. Confirm that refreshing the page does not erase the reward.
  6. Confirm that resubmitting the same already-claimed observation does not duplicate it.
  7. Confirm that a digital test image still receives no physical rewards.

Run the relevant regression tests and npm run build.

Final report

Tell me:
- The exact root cause.
- The files changed.
- The actual eligibility and reward results from testing.
- Whether the item appeared in the Sanctuary after refresh.
- Any remaining limitations.

Do not claim the issue is fixed unless the full reward flow has been verified.

Agent

I will systematically trace and debug the 7-stage photo discovery and reward pipeline:

  1. Inspect Pipeline Components: Check discovery-agent.js (evaluateEvidenceEligibility), dashboard-state.js (claimObservationRewards), and dashboard.js (showDiscoveryReveal).
  2. Run Baseline Regression Tests: Execute existing mock test suites (test_evidence_integrity.js and test_player_journey.js).
  3. Reproduce Live Inference Failure: Test real outdoor photos (test.jpeg), night sample photos (p01_a.jpeg), and multi-angle trees (p05_a.jpeg) through local Ollama (Qwen3-VL-2B) and the evidence gate.
  4. Identify Exact Root Cause: Pinpoint why eligible photos are tagged as 0 DM / Field Study Record.
  5. Apply Targeted Fixes: Safeguard evidence classification, ensure idempotency, decouple technical errors from synthetic rejections, and verify Sanctuary inventory persistence.

The mock test suite passes 50/50 checks because mock fixtures do not include typical epistemic hedges produced by live vision LLMs. Now, let's create a scratch test harness that sends real photograph files directly to local Ollama (Qwen3-VL-2B-Instruct) and evaluates them against evaluateEvidenceEligibility.

Root Cause Discovered

The reproduction output exposes the exact breakdown:

  1. Epistemic Hedge Leakage in evaluateEvidenceEligibility:
    When processing test.jpeg (a genuine outdoor tree), Qwen3-VL-2B correctly sets scene_type: "physical_outdoors". However, in its scientific uncertainty disclosure, it outputs:
    "uncertainties": ["the exact species of the tree is not identifiable", "the photograph may be a digital rendering or a screen capture, but the scene is clearly outdoors"]
    evaluateEvidenceEligibility concatenated structuredAnalysis.uncertainties into allModelText. The synthetic detector matched 'digital rendering' and 'screen capture' against the model's own doubt clause, demoting genuine outdoor photos to status: 'uncertain' with isRewardEligible: false and 0 DM.

  2. Misleading Sample Photo Default:
    #btn-load-sample-photo was hardcoded to p01_a.jpeg, a night street sign set against a pitch-black background. The vision model classifies this as scene_type: 'indoor', which rightfully earns 0 DM, giving testers the false impression that outdoor detection is globally broken.

  3. Popup Error Conflation:
    showDiscoveryReveal in dashboard.js defaulted technical errors and unverified states to the synthetic Field Study Record / 0 DM screen instead of offering a retry.

Now applying minimal, targeted fixes.

Let's rerun our diagnostic script scratch_test_photos.js against the live local Ollama model to verify that genuine outdoor photos now receive full physical rewards and eligibility.

The fix is verified in live inference: test.jpeg and p05_a.jpeg are now classified as status: 'eligible', isRewardEligible: true, allowPhysicalRewards: true. Now running the full regression suite and production build.

Root Cause Analysis

Tracing the 7-stage submission flow identified three compounding causes that caused outdoor photos to produce the "Field Study Record" (0 DM) popup:

[1. Upload Photo] ──> [2. Local Qwen3-VL] ──> [3. Eligibility Gate] ──> [4. Candidates & Claims] ──> [5. Inventory & Sanctuary]
                              β”‚                              β”‚                                             β”‚
                              β–Ό                              β–Ό                                             β–Ό
                     Outputs epistemic hedge        "allModelText" scanned          0 DM awarded; "Field Study Record"
                     under "uncertainties"          uncertainty phrase & demoted    popup shown; backpack left empty
                     ("may be a digital...")        eligible photo to "uncertain"
  1. Epistemic Hedge Leakage into Evidence Classification (discovery-agent.js:L310-375):

    • In Stage 2, Qwen3-VL-2B produces schema-valid JSON where the "uncertainties" key routinely contains standard scientific epistemic hedges (e.g. "the photograph may be a digital rendering or screen capture, but the scene is clearly outdoors").
    • In Stage 3, evaluateEvidenceEligibility concatenated parsed.uncertainties into allModelText alongside affirmative evidence fields.
    • The regex check matched phrases like 'may be a digital' against the model's own doubt statement, misclassifying genuine outdoor photos (test.jpeg, p08_a.jpeg, p03_a.jpeg) as status: 'uncertain' with isRewardEligible: false. Uncorroborated uncertain images were stripped of rewards (suggestedReward: 0, grantsItem: null).
  2. Sample Photo Button Loaded Night Road Signs (dashboard.js:L810-820 & discovery-agent.js:L1855):

    • The sample photo button in the testing drawer was hardcoded to /experiments/kill-test/photos/p01_a.jpeg (a night street sign with a pitch-black background).
    • The vision model classifies this dark background as scene_type: 'indoor', correctly triggering Case B (non-outdoor rejection with 0 DM). Testing the sample photo repeatedly gave the impression that all outdoor photos were broken.
  3. Inference Error & Synthetic Rejection Conflation in Popup (dashboard.js:L980-1010):

    • In Stage 7, showDiscoveryReveal checked isSynthetic = obs.eligibilityStatus === 'ineligible'.
    • When vision inference encountered a timeout, network hiccup, or missing analysis, evaluateEvidenceEligibility defaulted to ineligible, causing technical failures to display the synthetic rejection popup ("Field Study Record" / "Physical exploration unlocks living items") instead of an error state.
  4. Non-Deterministic Observation ID Derivation (discovery-agent.js:L215):

    • IDs were generated via obs_${Date.now()}. Re-uploading the exact same photo bypassed duplicate detection because the ID changed on every submission.

Remaining Limitations

  1. Local Vision Inference Server: Requires Ollama to be running locally (http://[REDACTED]:11434) with hf.co/Qwen/Qwen3-VL-2B-Instruct-GGUF:Q4_K_M. When Ollama is offline or times out, the app preserves the photo in the Field Journal and presents a clear retry button rather than misrepresenting it as an ineligible image.
  2. Extreme Low-Light / Night Photographs: Photos taken in pitch darkness without sky or horizon cues (such as p01_a.jpeg) may be classified as indoor/studio by the 2B vision model. Adding a short field note (e.g. "Night walk along the trail") provides immediate corroboration to unlock full outdoor rewards.

Prize Categories

Render: Try the UNSEEN frontend Render hosts the shareable frontend; the vision model still runs locally through Ollama. The deployed frontend does not, by itself, provide a hosted inference service.

The AI doesn't have to know everything. It just has to help us notice something worth going outside for.

And when it doesn't know, "I don't know" is an honest answer.
