Value CFL Suite

Independent Go implementation of the 25 V-CFL PRDs under /Users/Shared/product-docs/prd-core/v-cfl.

Properties:

• Go stdlib only (go.mod has an empty require block).
• One command per CFL under cmd/<binary-name>.
• Input: JSON on stdin.
• Output: deterministic JSON on stdout.
• Exit code: 0 for pass/approved/warn/pending success states, 1 for fail/block/rejected/timed_out, 2 for n/a/needs-human/pending-no-decision.
• Evidence hashes use sha256:<hex> over canonical JSON evidence payloads.

Build all binaries:

go build ./cmd/...

Run a binary:

echo '{"mode":"compute","bytes":"hello"}' | go run ./cmd/l0-v-hash-cfl
