OuterBrain

OuterBrain is the provider-neutral semantic-runtime gateway above Citadel.

It owns durable semantic-session truth, tool-manifest snapshots, prompt and strategy shaping, semantic quality checkpoints, live session fencing, provider-neutral semantic failure carriers, and restart-safe reply publication. It does not own provider memory, RAG engines, or model-specific cognition as platform truth.

Scope

• raw input normalization
• durable semantic state and journaling
• context assembly
• prompt and strategy shaping
• provider-neutral semantic failure normalization
• normalized semantic activity contracts with bounded routing facts
• semantic context provenance, duplicate suppression, and redaction evidence
• structured action-request synthesis
• provisional and final reply publication
• restart-safe downstream follow-up

Status

Active workspace buildout. The repo uses a non-umbrella workspace layout with core packages, a dedicated raw-Ecto persistence layer, bridges, a host surface, and proving examples.

Development

The project targets Elixir ~> 1.19 and Erlang/OTP 28. The pinned toolchain lives in .tool-versions.

mix deps.get
mix ci

The welded outer_brain_contracts artifact is tracked through the prepared bundle flow:

mix release.prepare
mix release.track
mix release.archive

mix release.track updates the orphan-backed projection/outer_brain_contracts branch so downstream repos can pin a real generated-source ref before any formal release boundary exists.

Temporal developer environment

Temporal runtime development is managed from /home/home/p/g/n/mezzanine through the repo-owned just workflow. Do not start ad hoc Temporal processes or rely on the temporal CLI as the implementation runbook.

Native Temporal development substrate

Temporal runtime development is managed from /home/home/p/g/n/mezzanine through the repo-owned just workflow, not by manually starting ad hoc Temporal processes.

Use:

cd /home/home/p/g/n/mezzanine
just dev-up
just dev-status
just dev-logs
just temporal-ui

Expected local contract: 127.0.0.1:7233, UI http://127.0.0.1:8233, namespace default, native service mezzanine-temporal-dev.service, persistent state ~/.local/share/temporal/dev-server.db.
