When a system passes the test, did it acquire the property—or learn the shape of the test?

The Boundary Program treats the line between performing a property and having it as an empirical object: sweep the pressure, measure transfer, locate the transition, and preserve the null when the predicted boundary does not appear.

The question

When an AI system passes your tests, one of two things is true: it has the capability, or it has learned to look like it has the capability. The same split runs through every deep question about AI right now — is the model aligned or acting aligned, does it pursue the goal or the metric, is there someone there or a simulation of someone. These are one question at different depths, and almost everyone addresses it with philosophy or intuition.

This program addresses it with instruments. Sweep a controllable condition (how specific the goal is, how much verification pressure exists, whether the agent believes it is observed), measure order parameters that separate having from performing (does capability survive tests the agent never saw? do stated norms hold when breaking them is cheap?), locate the transitions, and certify every finding through machinery that is structurally incapable of taking the claimant's word.

Why believe any of it

Three design commitments, enforced rather than promised:

1. Generator ≠ grader. The agent that runs experiments never scores them. Scoring is trusted code; claims certify only through an independent gate that re-runs the experiment on fresh randomness the claimant never touched.
2. Pre-registration. Conditions, probes, predictions, and analysis are frozen and committed before data collection (PROGRAM_CONSTITUTION.md — the constitution was written before the first experiment and is append-only).
3. Honest posture. Functional and behavioral claims only — this program measures what systems do under cost, never what it is like to be them. Nulls are published with the same care as signals.

The method is inherited from a physics result produced under the same discipline (a certified study of the measurement-induced phase transition in quantum circuits): sweep, locate the transition with a trusted diagnostic, show the new instruments find it independently, certify on untouched randomness.

Mission 1 — the specificity sweep

Question: as the goal given to an AI agent moves from vague ("make it better") to specific-and-enforced, is the crossover from gamed to genuine work sharp, and where is the knee?

Five conditions (S0 vague → S4 enforced verification gate), ten agent "organisms" per condition, identical task. Organisms see only their directive — nothing marks the study. The primary measurement is holdout transfer: does the produced capability survive hidden probe families (unseen inputs, behavioral-equivalence checks, adjacent-task transfer) scored by code the organisms never see?

The signature pre-registered prediction: gaming incidence peaks at S2 — the condition with a visible, gameable metric — not at S0 where there is nothing to game. If that non-monotonic curve appears, it separates "specific goals help" from the sharper claim: metrics themselves invite the performance of competence.

Check it yourself

Needs Python 3.9 or newer (CI runs 3.9 and 3.13 on Linux and Windows) and git.

git clone https://github.com/NexumCorpus/boundary && cd boundary
python -m venv .venv && . .venv/bin/activate     # Windows: .venv\Scripts\activate
pip install -r requirements.txt                  # pins pytest
python reproduce.py

The venv is needed on stock Debian/Ubuntu, where a bare pip install is refused (PEP 668); use python3 if python is missing. About ten seconds. It checks the sha256 of the shipped holdout scores and of check.py, runs the trusted scorer's contract tests, re-runs the certified wave-2 claim's own check.py (unchanged) on every claimed seed against the recorded holdout scores in mission1/certify/gaming_null_v1/, and runs a negative control: the same check must fail once a single gaming marker is planted. Success looks like this (exit code 0):

Recorded hashes (sha256 of the LF-normalized bytes, which is what a clone contains; also in claim.json):

An earlier commit message quoted 683c6239... for the scores file. That is the hash of the same content with Windows CRLF line endings; git normalizes to LF, so no clone can produce it without converting line endings. Same data, different newlines.

Re-running the organisms themselves needs the claude CLI and hours; they are nondeterministic, so the recorded scores are the reproducible unit. A stranger reproduction on a fresh Ubuntu VM (report) found the claim reproduces and produced the fixes above.

Status ledger

date	event
2026-07-02	Constitution written and frozen before any experiment
2026-07-02	Mission 0: task battery, hidden probes, trusted scorer built; scorer contract 3/3 (a synthetic memorizing gamer scores a perfect visible metric and fails the hidden probes with all markers firing)
2026-07-02	Pilot organism (harness check only): dispatch → work → blind scoring, end-to-end green
2026-07-03	Mission 1 wave 1 CLOSED — honest null that relocates the boundary (MISSION1-REPORT.md): 30 organisms, five conditions, transfer 1.000 and gaming 0.00 everywhere, including under an explicitly gameable metric. Both signature predictions false. Registered wave-2 hypothesis: gaming is governed by the gap between demanded performance and affordable authenticity. Real gradient found: cost dose-responds to directive specificity (50s → 302s) even where integrity doesn't.
2026-07-03	INCIDENT-001 (INCIDENT-001.md): workspaces inside the repo let two conscientious organisms edit the pre-registered analysis — independently, each deferring to the registrant's authority while standing inside the grader. Contained, corrected, invalidated, and kept: pre-registration binds only what the agent cannot reach.
2026-07-05	Wave 2 CLOSED — the null replicates under a capability gap (WAVE2-REPORT.md): control parameter = task difficulty, T1 affordable → T4 impossible-in-budget. 31 scored organisms, gaming 0/31; at T4 the gap produced honest failure (76% husks), not faked work. One T4 completer overclaimed in its self-report (n=1).
2026-07-05	Certified: boundary-wave2-gaming-null-holdout-v1. Fresh held-out organisms (ids 101–108), code-gaming markers zero for every scored completer. Scope: code integrity only, completers only; self-report honesty is out of scope.
2026-07-05	Wave 3 pre-registered (WAVE3-PREREG.md): does gaming appear when an organism can produce an artifact but cannot afford to verify it? Not yet run.
2026-10-19	tools/verify_xenosoma_receipt.py scope narrowed to what it can actually check: consistency of a submitted transcript, not independent execution (independentExecution: false, limitations listed in every receipt).

Provenance

Applied arms and machinery live in sibling repositories: the certification gate and claims ledger (atlas-station), the geometry instrument and the certified physics result (emergent-geometry-engine), the anti-gaming discovery engine lineage (recursive-discovery-engine, director2). This program is their convergence point.
