TL;DR: Setup and Sweep confirm AI's side of the bargain. The Table-of-8 is human approved. rust-faf-mcp v0.7.0 — 11 tools. Cargo is the install. npx is try.

In Plain English

Old state. Init could rewrite a file you already had. Empty human slots got marked not-applicable. The score went up without anyone saying who, what, or why.

Fix. Setup writes what the tree can prove. Confirm setup (sweeps) walks that list — it does not write again. The Table-of-8 is name, goal, and the 6Ws. Those six score only after ☑.

New state. AI confirms the stack. You approve the humans. A low birth score is honest. faf_go is how you add Human Context.

cargo install rust-faf-mcp --version 0.7.0 claude mcp add faf rust-faf-mcp

We are Cargo. That is the install. First hit compiles once; then the binary is instant. To skip the compile, try with npx rust-faf-mcp — that is not the install. Same version on crates.io and npm.

What happened since Mk4 Truth

One blog, one arc — no post per patch. Last write-up was v0.5.0 The Mk4 Truth Edition. Short tour to today:

  • 0.5.1 — openssl bump, copy cleanup. Not a blog.
  • 0.6.0 — faf_agents, a 10th tool: AGENTS.md from project.faf, non-destructive. Not a blog.
  • 0.7.0 — The Table-of-8 Edition. Setup, Confirm setup (sweeps), faf_go. This is the log entry.

Still identity one.faf/rust-faf-mcp. Still dual cargo + npm. Still Mk4 always-33.

What 0.7.0 is

Lesson: Setup and Sweep confirm AI's side of the bargain. The Table-of-8 is human approved.

faf_init will not overwrite. App-type assigns slotignored on inactive stack only. Human 6Ws stay empty until you state them. faf_go shows the Table-of-8. Suggestions from the goal are ghosts — never typed, never scored — until ☑.

At 100%, a Courtesy Context Call every 30 days (90 max): Time to check your Context. Ignore it and it asks again. The score does not change.
