1# Folio F0 baseline

3F0 freezes the current estate and entry-door contract without changing Folio product

4behavior. Run the gate only with the canonical estate as the read-only first argument.

5No-op and mutation probes require a disposable copy.

7```sh

8python3 tools/f0_inventory.py /home/daviwil/Ops/folio \

9 --positive-control --no-op-copy /tmp/folio-f0-copy \

10 --output /tmp/folio-f0-report.json

11```

13The accepted sabotage excludes one known canonical directory:

15```sh

16python3 tools/f0_inventory.py /home/daviwil/Ops/folio \

17 --omit-prefix notes/topics --output /tmp/folio-f0-sabotage.json

18```

20It must exit nonzero and name both the omitted files and denominator mismatch. The

21canonical corpus is never opened for writing by the tool.

23The deployed-product baseline drives the existing Folio binary over MCP with a

24disposable root. It measures cold initialize, status query, full index rebuild, one

25controlled inbox mutation, a warm post-mutation query, wall time, and peak child RSS.

26The source-level `f0_product_baseline.sgl` freezes equivalent library entry doors for a

27fresh build; neither harness is a product behavior change.
