After phase3_one_shot_runner produces synth netlist + DEF + GDS + STA + DRC reports, AI spot-checks design quality. Triggers on /vibe-ic-phase3 / /vibe-ic-phase23 PASS or phrases like "review backend", "check tapeout readiness", "verify GDS".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Phase 3 Backend Verification
> **Doctrine (v0.1.50):** 把修法寫進工具，而非寫進 prompt.
> Programs first; AI is the backstop on residual narrative.
## Mandatory Deterministic Preflight
```bash
python3 plugins/vibe-ic/programs/phase3_verify_aggregate.py \
<project_dir> \
--out-md /tmp/phase3_verify.md \
--out-json /tmp/phase3_verify.json --strict
```
The aggregator runs the shipped `phase23_completion_self_audit_check --json`,
`drc_report_check --mode drc --signoff --under reports/phase3/drc_signoff.rpt`,
`lvs_report_check --mode lvs --under reports/phase3/lvs.rpt`, and
`sta_report_check --mode sta --under phase3/stage3/sta/post_route_timing.rpt`.
It retains child stderr and unmeasured outcomes, reads canonical artifacts
before legacy aliases, and checks six required files. **Refuse to claim tape-out-ready
without DRC=0 AND WNS≥0 AND all backing checks PASS.**
**Purpose**: phase3 runner is a thin orchestrator over yosys / OpenROAD / KLayout / Netgen. PASS just means the tools didn't error. Whether the resulting silicon is FAB-ready is a separate question.
## Verification checklist
1. **Synth quality**:

How to install
mdr add vibeic/vibe-ic/phase3-backend-verify@sha256:bafa7cba32cec59cThe line at the top of this page pins the label git:20261015.359d5d4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
