Waiting for evidence

An operative answer is the current selection. Only a resolved status indicates sufficient support under this demo’s configured policy.

Why MoolBase reached this state

PROVENANCE, NOT JUST VOLUME

Evidence ledger

Copies sharing one evidence family do not become independent corroboration. Retired evidence remains visible in this ledger and in nonoperative audit records.

Download MoolBase

Start with the compiled DB. Add the examples to try agent memory, incident investigation and conflicting reports. Cloning the full repository is optional.

v0.6.0-alpha.2 developer preview · Packaging revision 1 · Compiled download: Linux x86_64 only. Use source for other supported build environments.

Compiled database

Linux x86_64. Compiled library, server, CLI, headers and CMake package. No DB implementation source, research or tests.

Run your first application

Download and extract the DB and examples ZIPs in the same directory. With C++20, CMake and Python 3:

export MOOLBASE_PREFIX="$PWD/moolbase-0.6.0-alpha.2-linux-x86_64"
cd moolbase-0.6.0-alpha.2-examples
cmake -S . -B build-showcase -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_PREFIX_PATH="$MOOLBASE_PREFIX"
cmake --build build-showcase -j2
python3 examples/customer_showcase/python_memory.py
python3 examples/customer_showcase/python_http.py \
  --server "$MOOLBASE_PREFIX/bin/graphenedb_server"

Memory correction: EU resolved → no operative answer → US resolved. The HTTP example also checks persisted evidence after restarting the server. Fixtures are synthetic; these are not customer case studies.

Complete install and integration guide GitHub release

The browser demo uses the actual engine with session-local files; refreshing starts fresh. Native examples persist to disk. Applications establish provenance, verification and retirement of stale copies. Prior reasoning state requires separate application persistence.
