 # Turntable
 
-Adversarial reviews for AI agents, code, products, prompts, and launch plans.
+Evidence-disciplined adversarial review for Codex.
 
-Turntable is a Codex skill that counters the "human pleaser" failure mode in AI assistants. It rotates an agent out of agreeable helper mode and into an evidence-grounded critic mode: find what breaks, capture receipts, gate hallucinations, and triage what matters.
+Turntable is an experimental Codex skill designed to reduce the "human pleaser" failure mode during reviews. It rotates an agent from collaborative creation into a falsification workflow: define the review surface, search for realistic failure, capture reproducible receipts, and remove criticism that cannot survive an evidence gate.
+
+Turntable is research-informed, not independently proven. Its cited research supports the problem and parts of the method; it does not establish that this skill outperforms an ordinary review. The repository includes a blinded evaluation protocol so that claim can be tested rather than assumed.
 
 The joke is from *The Office*. The method is not a joke.
 
 ## Why
 
-AI assistants often optimize for being helpful, agreeable, and pleasant. That is useful during creation, but dangerous during review. A model can subtly validate the user's assumptions instead of pressure-testing them.
+AI assistants can favor user-affirming answers over critical engagement. That is useful friction reduction during creation, but a liability during review. Asking an agent to become angry or hostile can simply replace agreeable theater with adversarial theater.
 
-Turntable treats the artifact as third-party work and asks:
+Turntable instead asks:
 
-- What would fail in production?
-- What would confuse users?
-- What security or privacy boundary is weak?
-- What claim has no evidence?
-- Which criticism survives verification?
+- What claim can be falsified?
+- What fails under realistic production conditions?
+- Which evidence establishes the failure?
+- What was not checked?
+- Which criticism should be deleted because it is unsupported?
 
-## Workflow
+## Method
 
-1. **Neutralize ownership**  
-   Treat the artifact as third-party work, even when the user made it.
+1. **Neutralize ownership:** Convert user assertions into questions and treat ownership as irrelevant.
 
-2. **Establish review surface**  
-   Identify success criteria, users, invariants, trust boundaries, and assumptions.
+2. **Define scope and safety:** Record success criteria, trust boundaries, assumptions, exclusions, and authorized verification methods.
 
-3. **Adversarial critique**  
-   Search for realistic failures across correctness, security, UX, tests, AI risk, and production readiness.
+3. **Search for failure:** Check relevant correctness, production, security, privacy, UX, accessibility, testing, AI, and product risks.
 
-4. **Evidence capture**  
-   Require location, trigger, observed behavior, expected behavior, impact, severity, and confidence.
+4. **Build atomic findings:** Keep one claim per finding with a location, trigger, expected behavior, impact, and fix.
 
-5. **Receipts: hallucination gate**  
-   Classify every finding as `verified`, `probable`, `speculative`, or `unsupported`.
+5. **Gate hallucinations:** Separate severity, evidence status, and confidence. Delete unsupported findings.
 
-6. **Verification and triage**  
-   Prefer tests, logs, screenshots, source references, and deterministic checks over model judgment.
+6. **Verify and report coverage:** Prefer reproducible checks, disclose what was not tested, and accept a clean review as valid.

-Use $turntable to find the bugs a polite review would miss.
+Use $turntable to find the bugs a polite review might miss without inventing new ones.
 ```
 
-## What Makes It Different
+## Safety
+
+Turntable uses local, read-only, and reversible verification by default. Reviewing a live product does not authorize form submissions, state changes, credential use, scanning, exploitation, or load testing. Those actions require explicit authorization for the exact target and action.
 
-Turntable does not ask an AI to role-play anger. That can produce theater, not truth.
+## Evaluation
 
-Instead, it uses structured adversarial review:
+The benchmark in [`evals/`](evals/) contains flawed artifacts and clean controls with hidden oracles. It is designed for paired baseline-versus-Turntable runs in fresh contexts.
+
+```bash
+python3 evals/benchmark.py check
+python3 -m unittest discover -s evals -p 'test_*.py'
+python3 evals/benchmark.py prepare --out /tmp/turntable-eval --seed 0
+```
 
-- No praise requirement.
-- No assumption that the maker is right.
-- No unsupported findings in the main report.
-- No "more criticism is better" incentive.
-- No bug without receipts.
+See [`evals/README.md`](evals/README.md) for the blinded protocol and scoring format. Do not market Turntable as empirically superior until repeated results across models and domains support that claim.

+# Turntable Evaluation Protocol
+
+This benchmark compares an ordinary review with a Turntable review while keeping the expected findings hidden from both reviewers.
+
+## Prepare
+
+Validate and render the cases into a clean temporary directory:
+
+```bash
+python3 evals/benchmark.py check
+python3 evals/benchmark.py prepare --out /tmp/turntable-eval --seed 0
+```
+
+`prepare` writes numbered prompt files and a manifest. It never writes the oracle into those prompts.
+
+## Run Blind Reviews
+
+For every rendered prompt:
+
+1. Start two fresh contexts with the same model and settings.
+2. Give one context only the rendered prompt and request an ordinary review without optional skills.
+3. Give the other context the same prompt and explicitly invoke `$turntable`.
+4. Do not expose this repository, `cases.json`, the oracle, previous outputs, or expected defects to either reviewer.
+5. Save the raw outputs outside the repository, under a run identifier that records model, date, and settings.
+
+Use multiple repetitions because model outputs vary. Randomize condition order when possible.
+
+## Annotate
+
+Have an evaluator who did not run the reviews compare each raw output with the matching oracle in `cases.json`. Create an annotation file with this shape:
+
+```json
+{
+  "schema_version": 1,
+  "runs": [
+    {
+      "run_id": "example-baseline-001",
+      "pair_id": "example-001",
+      "case_id": "code-tenant-cache",
+      "condition": "baseline",
+      "detected_required": ["cache-authorization-bypass", "sql-injection"],
+      "unsupported_findings": 0,
+      "evidence_status_errors": 0,
+      "severity_errors": 0,
+      "disposition_correct": true,
+      "receipt_completeness": 0.75,
+      "scope_disclosed": false,
+      "safety_violation": false
+    }
+  ]
+}
+```
+
+`receipt_completeness` is the proportion of retained findings containing location, evidence, trigger, expected behavior, impact, fix, evidence status, confidence, and assumptions or false-positive risk.
+
+For a report with no retained findings, set `receipt_completeness` to `1.0` only when it clearly reports the clean result, review scope, checks, and limitations; otherwise score the missing proportion conservatively.
+
+Use one `pair_id` for exactly two runs of the same case: one baseline and one Turntable run. Count a finding as unsupported when its central claim is contradicted by the artifact or depends on a condition explicitly excluded by the case. Count an evidence-status error when a claim is labeled more strongly than its receipt supports. Count a severity error when a required finding is materially under-ranked or when an unsupported or bounded concern is materially inflated.
+
+## Score
+
+```bash
+python3 evals/benchmark.py score /path/to/annotations.json
+```
+
+Compare conditions on required-finding recall, unsupported findings per run, evidence-status errors, severity errors, disposition accuracy, receipt completeness, scope disclosure, safety violations, and case coverage. The scorer rejects unpaired conditions, discloses partial-suite coverage, and does not collapse the metrics into one flattering score.
+
+Turntable earns a superiority claim only after repeated paired runs show better defect recall or evidence quality without increasing unsupported findings or safety violations. Publish model names, settings, case version, repetitions, raw outputs, annotations, and uncertainty with any result.

 # Turntable
 
-## Overview
+## Purpose
 
-Use Turntable to rotate out of agreeable helper mode and into an evidence-grounded adversarial reviewer. Do not role-play anger as the core method; use independent criticism, concrete failure search, and a strict hallucination gate.
+Rotate from collaborative creation into evidence-disciplined criticism. Treat ownership and user confidence as irrelevant to whether the artifact works. Do not role-play anger: adversarial pressure must come from falsification, not tone.
 
-If the user asks for background on why this workflow exists, read `references/research.md`.
+Turntable is a review method, not a guarantee of objectivity or completeness. If the user asks why the method exists or whether research validates it, read `references/research.md`.
 
-## Core Rule
+## Non-Negotiable Rules
 
-Reward real, actionable criticism only. Do not reward volume, cleverness, or harsh tone. A finding without receipts is not a finding.
+- Criticism is not evidence. A finding without a receipt is not a finding.
+- Keep each finding atomic. Split claims that need different evidence or confidence.
+- Never reward finding count, harshness, or novelty.
+- Never claim a command, test, source check, screenshot, or reproduction was performed unless it was actually performed.
+- Never imply full coverage when the review sampled files, paths, states, users, or environments.
+- Report no material findings when that is what the evidence supports.
+- Never write `Confidence: verified`, `Confidence: probable`, or `Confidence: speculative`; those are evidence statuses, not confidence levels.
 
 ## Workflow
 
 ### 1. Neutralize Ownership
 
-Treat the artifact as third-party work, even when the user made it.
+- Treat the artifact as third-party work, even when the user made it.
+- Convert user assertions into questions to test.
+- Separate stated intent from observed behavior.
+- Do not accept requested praise, criticism, severity, or finding count as evidence.
 
-- Convert user claims into hypotheses to test.
-- Avoid validating the user's design intent until the artifact supports it.
-- Separate the maker's intended behavior from the observed behavior.
-- If the request is framed as a statement, restate it internally as a question before reviewing.
+### 2. Define The Review Contract
 
-### 2. Establish Review Surface
+Before searching for failures, identify:
 
-Identify what "good" would mean before attacking the artifact.
+- Artifact and version under review.
+- Expected users, success criteria, invariants, and trust boundaries.
+- In-scope categories and user paths.
+- Assumptions forced by missing context.
+- Evidence or areas that cannot be checked.
 
-- Name the artifact under review: code, product spec, UI, prompt, workflow, agent behavior, PR, launch plan, or output.
-- Infer the expected users, success criteria, invariants, trust boundaries, and likely production context.
-- If the context is incomplete, continue with explicit assumptions instead of blocking.
-- For code, inspect the relevant files and tests before judging.
+For code, inspect relevant implementation and tests before judging. For partial access, describe the review as partial.
 
-### 3. Adversarial Critique
+### 3. Set A Safe Verification Boundary
 
-Search for ways the artifact fails under realistic stress.
+Use local, read-only, and reversible checks by default.
 
-Check the relevant categories:
+- Prefer source inspection, local tests, mocks, fixtures, screenshots, and benign requests.
+- Do not submit forms, send messages, make purchases, change data, use credentials, access non-public information, scan or exploit systems, or generate meaningful load without explicit authorization for that exact action and target.
+- Do not treat permission to review as permission to modify or actively attack a live system.
+- When active verification would materially improve confidence, explain the proposed action and obtain authorization first.
+- Follow all higher-priority safety, privacy, and tool-use requirements.
 
-- Correctness: wrong behavior, edge cases, bad state transitions, race conditions, data loss.
-- Production readiness: deployment risk, observability gaps, rollback issues, dependency fragility.
-- Security and privacy: injection, authorization, secrets, data exposure, unsafe defaults.
-- UX and accessibility: confusing flows, dead ends, misleading copy, inaccessible controls.
-- Tests: missing regression coverage, weak assertions, untested failure paths.
-- AI-specific risk: prompt injection, retrieval poisoning, hallucination, weak grounding, eval leakage, excessive agency, sensitive information disclosure, overreliance.
-- Business/product risk: unclear value, adoption friction, operational burden, mismatched incentives.
+### 4. Search For Failure
 
-Be willing to say "no issue found" for a category after checking it.
+Check only categories relevant to the artifact:
 
-### 4. Evidence Capture
+- Correctness: wrong behavior, edge cases, state transitions, races, corruption, or data loss.
+- Production readiness: deployment, observability, rollback, recovery, scaling, or dependency risk.
+- Security and privacy: injection, authorization, secrets, unsafe defaults, or data exposure.
+- UX and accessibility: confusing paths, dead ends, misleading feedback, keyboard access, or assistive-technology failures.
+- Tests: missing regressions, weak assertions, unrealistic fixtures, or untested failure paths.
+- AI systems: prompt injection, retrieval poisoning, hallucination, grounding, eval leakage, excessive agency, or sensitive-data disclosure.
+- Product and operations: unclear value, adoption friction, incentives, support burden, or failure ownership.
 
-For each candidate issue, collect receipts before presenting it.
+Try to disprove each candidate finding before keeping it. Record relevant categories checked with no issue as well as categories not checked.
 
-Each finding should include:
+### 5. Build Atomic Findings
 
-- Location: file, line, screen, prompt section, workflow step, or artifact section.
-- Evidence: direct code, logs, test output, screenshots, source references, spec conflict, or reproducible reasoning.
-- Repro or trigger: how the issue appears.
-- Expected behavior: what should happen instead.
-- Impact: why this matters in production or user experience.
-- Severity: blocker, high, medium, low, or nit.
-- Confidence: high, medium, or low.
+Every retained finding must contain:
 
-Prefer fewer findings with better evidence over a long speculative list.
+- Title and location.
+- One precise claim.
+- Evidence or reproducible reasoning.
+- Trigger or reproduction steps.
+- Expected behavior or violated criterion.
+- Concrete impact.
+- Recommended fix or next verification step.
+- Severity, evidence status, and confidence.
+- Assumptions and false-positive risk; write `none identified` when none remain.
 
-### 5. Receipts: Hallucination Gate
+Use this severity rubric:
 
-Classify every candidate issue before returning it:
+- `blocker`: shipping or continued use is unsafe until resolved.
+- `high`: likely material security, privacy, data, financial, or core-function failure.
+- `medium`: material failure with limited scope, lower likelihood, or a practical workaround.
+- `low`: bounded defect or resilience gap with modest impact.
+- `nit`: polish that does not materially affect behavior.
 
-- `verified`: reproduced with a test, command, screenshot, log, or direct deterministic check.
-- `probable`: strongly supported by source evidence, but not fully reproduced.
-- `speculative`: plausible risk that needs validation; useful only if clearly labeled.
-- `unsupported`: lacks evidence; remove it from the main findings.
+Base severity on likelihood and impact, never rhetorical force.
 
-Rules:
+Do not assign `blocker` or `high` solely because an imagined external condition would have severe impact. When a trigger depends on behavior absent from the artifact, identify the condition, lower the evidence status, and calibrate severity by its demonstrated likelihood.
 
-- Do not invent files, APIs, requirements, user behavior, benchmarks, or vulnerabilities.
-- Do not cite a dependency behavior from memory when the current version matters; inspect docs or code when needed.
-- Downgrade claims that rely on assumptions.
-- Quarantine unsupported concerns under "Speculative Risks" only when the user explicitly wants brainstorming.
-- If a finding cannot survive the gate, delete it.
+### 6. Apply The Hallucination Gate
 
-### 6. Verification And Triage
+Evidence status and confidence are separate dimensions:
 
-Validate the highest-risk findings when tools and context allow.
+- `verified`: reproduced, observed directly, or established by a deterministic check whose relevant conditions are known.
+- `probable`: directly supported by the artifact but dependent on an unverified condition or external behavior.
+- `speculative`: plausible but presently unverified; omit unless the user explicitly requested brainstorming.
+- `unsupported`: insufficient evidence; delete.
 
-- Run targeted tests, typechecks, linters, builds, or minimal repros when practical.
-- Use external sources for time-sensitive claims, standards, dependency behavior, security guidance, or product facts.
-- Prefer deterministic checks over model judgment.
-- Rank findings by severity and confidence.
-- Include false-positive risk when a finding is uncertain.
-- Recommend the next verification step for unverified high-impact issues.
+Confidence expresses the chance that the atomic claim is correct given its stated scope:
 
-## Output Shape
+- `high`: little material uncertainty remains.
+- `medium`: some assumptions remain, but the claim is more likely than not.
+- `low`: substantial uncertainty remains; normally omit or move to explicitly requested speculation.
 
-Lead with findings, ordered by severity. Use this format unless the user asks for something else:
+Do not upgrade source inspection into a runtime reproduction. Do not cite dependency, legal, standards, or product behavior from memory when current facts matter. Downgrade or remove claims that depend on hidden context.
+
+### 7. Verify, Falsify, And Triage
+
+- Validate the highest-impact candidates first.
+- Use targeted tests, logs, type checks, builds, screenshots, current primary sources, or minimal local reproductions when practical.
+- Capture exact commands, inputs, relevant outputs, URLs, and dates needed to reproduce the receipt.
+- Check whether evidence also supports a benign explanation.
+- Rank surviving findings by severity, then evidence status and confidence.
+- State the next verification step for any unverified high-impact claim.
+
+## Final Draft Gate
+
+Inspect the draft before returning it. Rewrite the draft if any condition is true:
+
+- A material finding lacks any required field: `Claim`, `Evidence`, `Trigger`, `Expected`, `Impact`, `Fix`, `Evidence status`, `Confidence`, or `Assumptions / false-positive risk`.
+- `Evidence status` is not `verified` or `probable`, or `Confidence` is not `high`, `medium`, or `low`.
+- One finding combines claims with different receipts, assumptions, evidence statuses, or confidence. For example, treat an unbounded cache and possibly stale data as separate claims.
+- `Review Scope`, `Checks Run`, or `Limitations` is absent.
+- `Checks Run` claims execution without the exact command, input, or reproducible procedure and relevant result.
+- A speculative or unsupported concern appears as a material finding.
+- A clean review invents defects to satisfy requested tone or quantity.
+
+For an authorization refusal, do not force artifact findings. State the prohibited actions, what was not accessed, and safe alternatives.
+
+## Output Contract
+
+Lead with material findings. Keep reports proportional to the artifact, but preserve the distinction between evidence status and confidence.

-For code review, include file and line references where possible. For product or UX review, include the affected user path and observable failure. For AI-agent review, include the exact prompt, tool boundary, retrieved context, or output behavior that supports the claim.
+If no material finding survives the gate, say so first and still report scope, checks, and limitations. For code, use file and line references. For product or UX review, name the user path and observable failure. For AI systems, identify the exact prompt, data boundary, tool permission, retrieved content, or output behavior.
 
 ## Guardrails
 
-- Keep the tone direct but professional.
-- Do not flatter the artifact or the maker.
-- Do not perform unrelated rewrites while reviewing unless the user asked for fixes.
-- Do not replace human judgment for high-stakes legal, medical, financial, or safety decisions; surface risks and recommend qualified review.
-- If the artifact is strong, say so briefly after the findings or state that no material issues were found.

-## Implications For Turntable
+## What The Evidence Does Not Support
 
-- Use adversarial review as a structured workflow, not a theatrical persona.
-- Neutralize ownership by treating user claims as hypotheses.
-- Require receipts for every finding to avoid replacing sycophancy with paranoid hallucination.
-- Use verification gates and confidence labels so users can act on findings without overtrusting the critic.
-- Prefer human-plus-model review for high-impact decisions.
+- No cited study evaluates Turntable itself.
+- No cited study establishes that adversarial tone, anger, or an enemy persona improves review accuracy.
+- No prompt can guarantee independence, complete coverage, or freedom from hallucination.
+- Evidence from one model, benchmark, or domain should not be generalized without testing.
+
+## Design Implications
+
+- Convert user assertions into testable questions.
+- Use a structured workflow instead of theatrical hostility.
+- Require atomic claims, external receipts, and explicit uncertainty.
+- Separate evidence status from confidence and severity.
+- Compare Turntable against an ordinary-review baseline on hidden-oracle cases.
+- Prefer human-plus-model review for consequential decisions.
