`huginn-daemon` serves a mind, so the README and AGENTS say what it serves, over which envelope, in which order it starts, and where its two published schemas live. `eureka-state` is the remaining stub. The command block gains the daemon's own invocation. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# Huginn
|
|
|
|
Huginn is the GameCult memory organ. It owns each agent instance's mind as
|
|
typed state: what an instance remembers, which of that memory is admitted to
|
|
steer its next action, and the provenance of every admitted claim.
|
|
|
|
Upstream: `https://github.com/GameCult/Huginn.git`
|
|
|
|
## Authority
|
|
|
|
- An instance owns its mind; Huginn owns the state. Huginn is the single
|
|
writer of an instance's memory documents. No other service, script, or agent
|
|
writes them.
|
|
- Memory documents are CultCache state. `huginn-mind` persists them through
|
|
CultLib's Rust CultCache into a redb store at
|
|
`<state_root>/minds/<instance>/mind.redb`. `huginn-daemon` serves one such
|
|
mind over CultNet RUDP: admission and the read side ride
|
|
`cultnet.operation_request.v0` and `cultnet.operation_response.v0`, and the
|
|
two wire schemas answer a schema catalog request.
|
|
- Retrieval is to depend on Qdrant directly, refusing loudly when Qdrant is
|
|
unreachable rather than falling back to a second store or a second writer.
|
|
No crate opens that connection yet.
|
|
- Mind state is not version-controlled. It lives in Huginn's store, not in
|
|
any repository.
|
|
|
|
Generic `.cc` inspection is not Huginn's job. CultCache Studio inspects and
|
|
edits `.cc` state. Huginn reads and writes minds.
|
|
|
|
## Layout
|
|
|
|
A Cargo workspace of three crates:
|
|
|
|
- `crates/huginn-mind`: storage, identity, admission, and queries and derived
|
|
status over memory documents.
|
|
- `crates/huginn-daemon`: the CultNet surface. The socket, the sessions, the
|
|
process and the operation envelope, and no rule.
|
|
- `crates/eureka-state`: a stub. It will carry typed state for the Eureka
|
|
pipeline; today it holds none.
|
|
|
|
`huginn-mind` is live: it opens one instance's store (an owned redb CultCache
|
|
at `<state_root>/minds/<instance>/mind.redb`, locked for the mind's lifetime),
|
|
and refuses a store whose `instance` document names another instance, whose
|
|
epoch record is foreign, or whose types are not a mind's. It admits batches
|
|
of pipeline documents through one commit path: the leaf's bounds, formats and
|
|
keys, then the organ's cross-document rules (references, in-force status,
|
|
the resolution matrix, derived resolutions and stewardships), then one
|
|
compare-and-swap that lands the batch whole with a receipt naming the exact
|
|
bytes it read and wrote. An exact replay answers with the stored receipt.
|
|
It reads them back the same way: a document with the facts of its admission
|
|
joined from that receipt and its status derived at read time, typed queries
|
|
over one mind, a campaign's open work, and a subject's or a repo's history.
|
|
Status is never stored, and the views derive it through the same rules
|
|
admission does. Document shape and keys come from `epiphany-pipeline`; the
|
|
store is CultLib's Rust CultCache.
|
|
|
|
`huginn-daemon` opens one mind, binds one UDP socket in that order, and
|
|
answers every frame on the session it arrived on: one operation per `Mind`
|
|
method plus `whoami`, whose payload is the mind's own types as named
|
|
MessagePack. A refusal is an answer with a `rejected` status, never a
|
|
transport error; an envelope that does not decode is answered with a typed
|
|
failure and reaches no mind. The two schemas it publishes live in
|
|
`schemas/cultnet/` and are pinned to their derivation by a test. There is no
|
|
index yet.
|
|
|
|
`eureka-state` is a stub; the campaign's cut map in
|
|
`Epiphany/notes/eureka-pipeline-state-cut.md` owns what each crate must do
|
|
next.
|
|
|
|
```powershell
|
|
cargo check --workspace
|
|
cargo run -p huginn-daemon -- --state-root <abs> --instance <slug> --bind 127.0.0.1:17872
|
|
```
|
|
|
|
## Persona
|
|
|
|
Huginn's legacy repo Persona lives under `.voidbot/`. Its `state/huginn.cc`
|
|
holds legacy `void.*` documents and its `voice/identity.json` names the
|
|
Persona. The two disagree about jurisdiction; that migration belongs to the
|
|
portable-Persona work, not to this workspace, and nothing here reads or writes
|
|
`.voidbot/`.
