# Tieline → our process (not HVAC, not their product) Source: [knoxgraeme/tieline](https://github.com/knoxgraeme/tieline) (2026-08-18). ICP is agent-coding / product-intent, **not** HVAC owners. Transfer is fleet process. Do not rebuild Tieline. Do not `npx tieline`. ## What we steal | Tieline | Here | |---------|------| | Capability → Story → AC → evidence | `.intent/contract.yaml` | | `tieline check --base` | `node scripts/intent-check.js --base origin/main` | | Graded evidence (`supported` / `partial` / `unsupported`) | Same grades + `broken` for missing paths | | AC-aware blast radius | Changed files → affected AC keys | | Merge is acceptance | YAML travels with the PR | | Do not AC-fill unmapped files | `blast.unclaimed` is a question, not a fail | ## What we do not steal Postgres sync, MCP planning tools, Tree-sitter topology, `npx tieline`, invented SKUs, Cloud-vs-Local as a second paid product, digital-employee stats. ## How this improves *our* system 1. **Silent offer regressions become exit 1.** A deleted `$10/mo` string or a revived "ThumbGate Wake" card fails `OFFER-001` / `START-001` before review. 2. **Agents get a neighborhood, not the whole repo.** `--path HostingSelector.tsx` returns `HOST-001-AC1` instead of grepping 50k lines. 3. **PR closeout names blast radius.** `--base origin/main` lists ACs the diff may have broken. Complements `/grade-completion-claims` (chat claims) and `/check-stale-vault-claims` (vault leases). ## Protocol 1. B
