Merge Risk: 🔵 Low · up to 7133b
Windows setup remains incomplete, two launch drafts cannot be posted as written, and one launch claim may overstate the published server’s proof enforcement. These are low-risk readiness issues rather than product failures.

Add Windows activation instructions.
source .venv/bin/activate does not work in PowerShell or cmd.exe. Windows contributors cannot complete the documented setup flow. Add the PowerShell and cmd.exe activation commands, or use python -m pip commands that do not require activation.

| Fable Mode is an open-source (MIT) MCP server that puts four gates in front of the workspace: | ||
|
|
||
| 1. **Think** – a hard time-lock. The agent literally cannot write code until the deliberation budget elapses. Trying to unlock early raises a PermissionError, not a warning. | ||
| 2. **Prove** – claims must carry evidence: tool receipts, SHA-256 checksum chains, AST-grounded invariants. Tautologies are filtered out. |

Narrow the proof claims to the published server. fable-engine and fable-v1 map to fable_engine.server:main, which dispatches fable_session without importing the fable_v2 proof validator. The SHA-256, AST, and anti-tautology checks exist under the separate fable-v2-broker path. They do not establish enforcement by the advertised server.
