# Proof of Work
The Amdahl-shrink move from the Orchestration Tax: human review is the serial bottleneck, so don't spend it confirming what a machine can verify. An agent's diff is **review-ready** only when the machine-verifiable battery is green — types, tests, lint (and a screenshot for UI). What a machine can prove shouldn't cost a human's attention.
## The gate
Run the battery on the current working tree:
```bash
PROOF_RUNNER="${CODEX_HOME:-$HOME/.codex}/darkroom/source/src/scripts/proof.ts"
[ -f "$PROOF_RUNNER" ] || PROOF_RUNNER="$HOME/.claude/src/scripts/proof.ts"
bun "$PROOF_RUNNER"
```
This is the portable installed runner — it works in any repo. (`bun run proof` is a shortcut that only exists inside the cc-settings repo itself; don't reach for it in a consumer project.) It detects `typecheck` / `test` / `lint` from the project's `package.json`, runs them cheapest-first, and prints one verdict:
- exit 0 → `review-ready ✓`
- exit 1 → `NOT review-ready ✗` — fix the failing gate before a human looks
Projects can opt into **advisory** probes by depending on the tool — the gate then runs the project's pinned binary: **react-doctor** (React render/quality score, telemetry off) and/or **deslop** (framework-agnostic cross-file dead-code count). Advisory results are reported but never flip the verdict — deterministic signals alongside the hard gates, not blockers. Silent for projects that don't depend on them.
For UI changes, attach a screenshot (`/qa` or the chrome-devtools MCP) as the visual half of the proof — tests can't prove "looks right".
## Standalone Codex semantic probe
Use `spawn_agent` to create a fresh read-only `reviewer`, `send_message` to
deliver context while it runs, `followup_task` to trigger another turn once it
is idle, `wait_agent` to wait, and `interrupt_agent` only to stop its current
turn. Treat findings as advisory beside
the mechanical verdict. Never spawn `codex-verifier` and never run `codex-run.ts` from inside Codex.
Skip the Claude bridge branch below.
Writers share the working tree unless the live host explicitly offers
isolation. Only read-only reviewers may overlap; serialize any implementer and
test-writer remediation with non-overlapping ownership. For UI proof, use the
Chrome MCP only when the user configured it. Otherwise use native/manual
screenshot tooling and state what could not be visually verified. This package
does not auto-run unpinned registry MCP packages.
## Advisory: cross-model semantic probe (when the Codex bridge is available)
The mechanical battery proves the diff is *self-consistent* — it compiles, tests pass, lint is clean. It cannot prove the diff is *correct*: a bug that typechecks and passes the tests you wrote sails straight through. When the Codex bridge is available, add a semantic probe from a different model family on top of the mechanical gate:
```bash
bun "$HOME/.claude/src/scripts/codex-run.ts" review
```
Treat it exactly like react-doctor and deslop: **advisory — reported alongside the verdict, never flips it.** A green mechanical gate stays review-ready even if Codex raises a finding; surface the finding for the human to weigh, don't block on it. The bridge is gated and fails open — silent when Codex isn't installed, authed, or has quota.
Keep it **out of `bun run proof` itself.** That gate is cheapest-first and runs constantly; a remote model call would make every proof slow. Run this probe by default on every diff-producing task when the bridge is available — skip it only for a trivial one-line/typo diff, which also keeps it cheap regardless of how roomy the Codex window is.
## The contract
- A diff-producing agent (implementer, scaffolder, maestro, deslopper) **attaches a proof report before handing back**. "Done" without green proof is not done.
- The human/reviewer spends the lock on judgment — architecture, intent, edge cases — not on re-running what the gate already proved.
- Pairs with the review-queue: backpressure (`the review-queue branch of tool-cadence.ts`) limits how many *unproven* diffs pile up; this gate makes each one cheaper to close.
## When NOT to gate
Pure-research or read-only agent output (explore, oracle) has no diff to prove — proof-of-work is for changes, not findings.
