Docker 29.6.2 is up. Checking host resources, then writing the sandbox images (egress allowlist proxy + non-root sandbox).

SDK shape is clear. Now writing the core modules: config, state DB, spend ledger, tracing, and the LLM client.

No secrets in the hook file. Committing.

While batch a finishes, I'm picking CPU-friendly dev papers for the v2 sanity check. Hand-picking is fine for dev, which exists for tuning. The held-out set will be run strictly in queue order.

Overall status is PARTIAL. Everything I can do is finished and pushed to the now-public repo, https://github.com/isHeSatoshi/paperci. The remaining items need a person: the cfo.ai plan, the demo video, the posts, the trace share links and the final submission. Each has exact steps in HUMAN_TASKS.md.

Held-out results (same 5 papers and sealed claims, v1 baseline vs v2 self-improved builder):

The honest gain is speed, cost and one validated task, not more faithful reproductions. When I checked the v2 builds by hand, 2 of the 3 were not faithful. One replayed a stored results file, and the same paper did this in v1 too. The other scored a formula the agent wrote itself instead of running the repo's code. The verifier now flags both cases. I re-checked every stored run with the stricter rules, and 3 packages were moved to registry/rejected/.

What changed this session:

• Oracle bug: the faithful held-out build first failed its own oracle check. The value it needed was split across two log lines, and a number in a section header was read as the result. After the fix its oracle earned reward 1.0. The v1 build of the same paper still fails its oracle and was rejected.
• Failure and recovery test: I stopped the network proxy on purpose before a repo download. The download failed, the pipeline restarted the proxy, the retry worked, and the failure was recorded as recovered. The agent then correctly gave up in 5 turns for $0.09 because the paper's data isn't released.
• Disk incident: drive C: filled up and Docker died during an oracle run. You freed space and I deleted the stale PaperCI build images. One dev build image alone was 17 GB. The pipeline now removes crashed containers, warns when the disk is low, and retries container crashes instead of counting them against the task.

Deliverables:

• Entire checkpoints (links are in hackathon.md):
  • 01M4KP3DNR0TF8TWQE611MJJYV on commit e70be0f
  • 01M4MKYQ3938RM8FJ5K9ETQ55A on commit e3b748d
• neatlogs traces:
  • Before/after pair on the same paper: 294209f0b2d1b60bfc1509fdbece2f1b (v1) and 4e85d604ac7a5d343950ee923f573502 (v2).
  • Recovery test: 14ed5fe7f083b2b1ff4c98fbbf705223. neatlogs failed to finalize this trace (status dlq), so it may not display. The recovery is also recorded in docs/evidence.md.
• Docs:
  • Generated from measured data: docs/evidence.md, docs/unit-economics.md (includes the cfo.ai entry sheet) and docs/dashboard_public.html (anonymized; no paper is named next to a verdict).
  • Filled in with the measured numbers: docs/posts.md and docs/demo-script.md.
  • Updated: hackathon.md, PROGRESS.md and HUMAN_TASKS.md.
• Spend: $5.44 of the $20 key. My ledger matches the spend the proxy reports.

Checks: the offline unit tests pass. The secret scan found 0 hits across the working tree, the full git history including checkpoint refs, and the session transcript before I attached it to Entire. I made the repo public only after that scan.

Caveats:

• n=5 is a small sample.
• Both validated tasks are reduced-scale runs that Haiku solved 0 of 2 times.
• C: still has only about 10 GB free because Docker's disk file doesn't shrink on its own. Optional steps to reclaim space are in HUMAN_TASKS.md item 0.

I tried to do the neatlogs dashboard work, but your CLI login can only read data, so I couldn't label or share traces. Everything else from this round is committed and pushed. Entire saved this conversation as checkpoint 01M4MNN3X23K0YACPFB290WFRG on commit 13388bd.

neatlogs dashboard

• What worked: I read every trace back through your CLI login. The numbers and trace IDs are in docs/evidence.md.

• Labels and comments: I tried to tag and rename the before/after/recovery traces so they're easy to find. neatlogs answered FORBIDDEN because the login only allows reading.

• Share links: the CLI can only check whether sharing is on, not turn it on. Public share links have to be made on the website. Making traces public would also show verdicts next to real paper names, which is why I didn't plan to publish them.

• neatlogs is having problems right now: its own health check (doctor --probe) passed all 8 checks yesterday and now fails ("stuck at pii_redaction"). 16 traces never finished processing (status dlq), and the newest run's trace hasn't shown up at all.

• What to show judges: you don't need links. Use the trace IDs in docs/evidence.md:

  • Before: 294209f0b2d1b60bfc1509fdbece2f1b
  • After, same paper: 4e85d604ac7a5d343950ee923f573502

  I also wrote docs/neatlogs-feedback.md, a ready-made bug report for the neatlogs Discord. Posting it is good sponsor engagement.

• Second recovery test: I ran the proxy-kill test again on another paper. It recovered again, and this time the failure got the new proxy_unreachable label I added after the first test.

What's built

PaperCI is "CI for arXiv": a bot that checks whether a new paper's code actually reproduces its numbers.

1. Watches new arXiv and Hugging Face papers that link a GitHub repo.
2. Filters out papers a CPU machine can't run: GPU-scale models, paid API keys, huge downloads.
3. Seals the paper's headline numbers, so the agent doing the work never sees what it has to hit.
4. Builds: an agent (Claude Sonnet) gets the repo's code running inside a locked-down Docker sandbox. It runs as a non-root user and can only reach approved package sites.
5. Verifies: a separate model family (Amazon Nova) reruns the code with no network and compares the results to the sealed numbers. It also checks for cheating: typed-in numbers, copied result files, replaying stored results, and code that never uses the repo.
6. Packages each faithful run as a Harbor-format task. A run counts only if its reference solution passes its own hidden test. A cheap model (Haiku) then tries the task to see how hard it is.
7. Improves itself: it learns rules from its own failures, enforces a turn budget, and adds packages it keeps installing to its base image. All of this is gated, and the judge, sealed numbers and held-out papers are off limits to it.
8. Heals itself: it restarts a dead proxy, cleans up crashed containers and retries infrastructure failures. The two recovery tests show this.

What we're pitching

• Problem: most papers' code is never re-run by anyone. Agent benchmarks go stale and leak into training data.
• Product: reproduction becomes a cheap, continuous, auditable signal, and every fresh paper can become a fresh, verified task for testing or training agents.
• Self-improvement:

• Honesty story: I audited our own wins. 2 of the 3 v2 builds were not faithful, so I hardened the verifier and re-judged every run. "Faithful reproductions: 1 → 1" stays in the pitch. Judges tend to trust this more than a perfect number.
• Business: a reproduction attempt costs about $0.21. About $0.18 of that is measured LLM spend; the compute part uses an assumed $0.17/hour CPU price. That's about $0.91 of LLM spend per verified held-out task, from one task, so treat it as rough. Pricing is a hypothesis: you could charge per verified task to labs and eval teams, or offer badges and audits to authors and venues. Possible customers are in docs/buyer-map.md, and the cfo.ai numbers are in docs/unit-economics.md.

Scale and scope (honest)

• Funnel:

• Cost and time: $5.66 of the $20 budget. One machine, CPU only; a run takes minutes per paper.
• Not done yet: GPU papers, full-scale runs and a large sample. The before/after comparison is only 5 papers, so it's evidence, not proof.
• Next: more held-out papers, a GPU worker class, and an improvement generation that learns from the new cheat flags.

Still yours

• cfo.ai plan
• Demo video (script in docs/demo-script.md)
• Posts (drafts in docs/posts.md)
• Final X submission on Mon 12 Oct, 7:00–11:55 PM IST
• Optional: post docs/neatlogs-feedback.md in the neatlogs Discord

PaperCI now works like CodeRabbit for papers: one command takes a paper and produces a pull-request-style review. I tested it end to end on a fresh paper: 11.9 minutes, $0.15. Everything is pushed with an Entire checkpoint (01M4MQWGPTEW7NN60B0TDQ1AZP).

What you get

• One command: python -m paperci review <arxiv-id> --anonymize --open runs the whole pipeline with live, CI-style output in the terminal. You see the paper's claims get sealed, each agent turn and command, the learned controller stepping in ("stop reading, run code"), the dry run with the network off, three offline reruns, the oracle replay and the cheap-solver attempts.
• The review page (HTML plus Markdown):
  • a pipeline strip of pass/fail steps;
  • a walkthrough of how the environment was built;
  • a claims-vs-measured table: what the paper says, what the code produced (mean ± spread over 3 reruns), the tolerance, and a status ("Reproduced", "Reproduced at reduced scale", "Differs", "Not measured", "Run not trusted");
  • CI-style checks, including anti-cheat;
  • suggestions for the authors, such as missing dependencies, data that isn't released, or numbers no script prints;
  • "reproduce it yourself", with the exact run script and every command the agent ran.
• Catches cheating: when a run replays stored results or never calls the paper's code, every claim is marked "Run not trusted". This is a real case from our own agent and makes a strong demo moment.
• For authors: a README badge (SVG) and a GitHub Action template that runs the review on each release. I haven't run the Action on GitHub yet; the file says so.
• README: rewritten around "CodeRabbit for papers", including your vision of moving from deterministic code to GPU work and then simulators (robotics, physics, chemistry). It has real, anonymized screenshots of the review page, the caught-cheating case and the live terminal.
• Browsable reviews: docs/reviews/index.html lists every review as anonymized pages. I checked them for paper IDs and titles and found none.

Stronger numbers

I ran the other 5 held-out papers so the before/after now covers all 10. Both versions are judged by the same strict rules:

The integrity checks threw out 3 runs in each version. Ten papers is still a small sample, so the docs call these signals, not proof.

Also fixed

• Disk: built Docker images are now deleted after each run (one had been 17 GB), and a batch stops if drive C: drops under 5 GB. C: never filled up again this round.

Total spend is $7.77 of the $20 budget.

For you

1. Record the demo with docs/demo-script.md (3:30, rewritten around the review). Run paperci review <fresh dev id> --anonymize --open while recording and speed it up. Pick an ID with python scripts\show_queue.py dev review 5.
2. Show only anonymized pages on screen, so no verdict appears next to a named paper.
3. Optional: turn on GitHub Pages for the docs/ folder so judges can click through the reviews online.
4. Still yours: the cfo.ai plan, the posts (docs/posts.md has a new "CodeRabbit for papers" post) and the X submission on Mon 12 Oct, 7:00–11:55 PM IST.

Dashboard is up and open in your browser (server PID 1960, serving registry/ only, so nothing outside that folder is reachable).

• Dashboard (private): http://127.0.0.1:8765/index.html
• Review index, anonymized (safe for recording): http://127.0.0.1:8765/reviews/index-public.html
• Review index, full: http://127.0.0.1:8765/reviews/index.html

All three pages returned 200. The dashboard was regenerated from the current database just now, so it includes the n=10 held-out comparison, the chaos/self-heal runs and the four validated tasks.

Two notes for the demo: use the index-public.html tab on screen, since the private dashboard shows paper titles next to verdicts. And the server dies with a reboot; restart it with the same command or just open the HTML files directly from disk.

Stop it when you're done:

Before I touch anything I need three inputs, because the flow branches on them (region default vs. the toolkit's fixed us-east-1, and which AWS rules file you get). Two things worth knowing up front: sign-in happens through aws login in your browser, and those credentials last 12 hours and can be renewed for up to 90 days without re-authenticating. I'm also checking prerequisites in parallel (uv, AWS CLI, network to awscli.amazonaws.com).

No AWS credentials on this machine at all (clean slate), so the browser login is the real gate. I also pulled the toolkit README, which gives me the exact MCP server form for agents the wizard doesn't know about — that's how I'll wire Droid, since the toolkit supports Claude Code, Codex, Cursor, Kiro and fx but not Factory.

Setting the Region, then starting the login. Watch for a browser window opening on your desktop — sign in with the account that has the credits (that console session with adityas-macbook-pro).

No credentials landed, so the flow needs to run again from scratch. Region is set (us-east-1 on profile neathack), which is the part that survived.

Starting the sign-in again now. Please:

1. Don't cancel this command — it must stay alive while you authenticate (that's what died last time).
2. Sign in in the tab that opens (close the old "Bad Request" tab).
3. Approve/continue until the browser says you can return to the terminal.

I'll wait up to 10 minutes.

Login is running detached (PID 15632) and it opened your browser. The authorization URL is in runs\logs\aws-login.log if the tab didn't appear — this run's callback is on port 62561.

Complete the sign-in in the browser (Continue with an active session → hackathon-user-009). I'll watch the log.

Sign-in is yours to do; meanwhile I'm not idle — the repo-side wiring needs no credentials. Doing that now: pulling the AWS skills and rules, checking what's tracked in git, and writing the MCP entry for this repo.

Clone exited 128 (checkout hiccup) even though content landed, so let me verify integrity and look at the skills layout before copying anything into the repo.

Fresh URL for your Incognito attempt — login PID 13260, callback port 62795:

Paste into Incognito → Sign into new session → 0822-2915-5562 / hackathon-user-009 / organizers' password.

Skills are installed meanwhile: 114 AWS skills (1,379 files) copied into .factory/skills/ in this repo, frontmatter is name + description, which is what Droid reads. Now checking Factory's exact MCP config contract so I write the AWS server into the right file, and verifying the MCP proxy package actually resolves before wiring it.

Docs confirm the project-level path works and auto-reloads. Verifying the proxy package name against the toolkit's own plugin configs and PyPI before I write the MCP entry, and writing the rules file now.

AWS is connected and proven working. The live test call went through the AWS MCP Server into your account and came back as arn:aws:iam::082229155652:user/hackathon-user-099 — so the whole chain (Droid → MCP proxy → SigV4 signing → AWS MCP Server → STS) is real, not just configured.

What's in place

Eight AWS tools are now live in my tool list: run_script, search_documentation, read_documentation, retrieve_skill, get_presigned_url, get_tasks, list_regions, get_regional_availability. Per the AWS rules I installed, I'll prefer these over shelling out to the CLI.

One thing I deliberately skipped

The setup doc's Step 5 wizard (aws configure agent-toolkit --yes) writes MCP entries and skills into every agent it detects on this machine — ~/.claude, ~/.codex, ~/.cursor, ~/.gemini, ~/.opencode. You said "just this repo", so I wired only this repo by hand using the toolkit's own published config schema instead. If you later want your other agents connected too:

Also worth knowing: the browser sign-in path was never going to work on this account — AWS's own signing-in-to-aws skill says the IAM identity needs the SignInLocalDevelopmentAccess managed policy, and that sandbox user has none. The access key was the correct call.

Security notes

• Those keys are now in this chat and in a screenshot, so treat them as exposed. Rotate them when the hackathon wraps if you care about the account.
• Verified clean: 0 commits in history contain the key, and Entire's captured prompt (.entire/metadata/.../prompt.txt) is gitignored, so it can't be committed by accident.
• .factory/mcp.json, .factory/skills/, and AGENTS.md are currently untracked. Committing them is your call — say the word and I'll commit them, or add .factory/skills/ to .gitignore if you want the public repo to stay lean (that folder is 1,379 files).
• If you ever want a safety switch, the proxy supports --read-only, which makes AWS treat agent calls as read-only via IAM context keys.

Open a new terminal and run aws --version to confirm v2 shows up. Then just ask me for AWS work in this repo — it'll go through the MCP server.

Netlify's config lives elsewhere. Listing existing sites to pick up the account slug, then retrying the create without the --team flag.

You're right, my call — and I've stopped. Cleaning up the Netlify site I just created so your account is back to how it was.

Then pick your host and I'll do it properly.

Both kits are ready and staged outside your repo (under gitignored runs/). Current auth status: you're logged out — vercel whoami says Logged out, so the browser step is still pending on your side.

What's waiting for you

Then, to go live (this is the other agent's or your one command):

What I prepared

Vercel — runs/verifix-live/vercel/

• vercel.json rewrites /(.*) to your Lambda, so page and API share one origin
• public/index.html placeholder that should never be served (rewrite wins)

Cloudflare (alternative) — runs/verifix-live/cloudflare/

• src/index.js Worker that proxies to the Lambda and strips the host header
• wrangler.toml — change name to pick the subdomain label

runs/verifix-live/README.md — the constraint, why it must be a rewrite rather than a redirect, both deploy recipes, verification steps, and rollback commands. Point the other agent at that file; it has everything it needs.

One bonus worth knowing: the CLI also supports vercel deploy --temporary, which produces a live URL with no login at all (you claim it later). Good if you want a working link in front of judges right now, at the cost of it being temporary.

Nothing was deployed by me, the Netlify site is deleted, and your repo has no new tracked files.

Committed and now verifying with a fresh manual run that the workflow ends green.
