# Epiphany Model Atlas vertical slice
|
|
|
|
Updated: 2026-08-14
|
|
|
|
## Objective
|
|
|
|
Let one repository notice a provider change, understand its direct and
|
|
transitive consequences, and wake its own Modeling lane without an operator
|
|
typing `Continue`. The Atlas carries evidence between local minds. It does not
|
|
become a shared mind and it never grants Hands authority.
|
|
|
|
## Authority map
|
|
|
|
| Concern | Owner | Inputs | Output |
|
|
| --- | --- | --- | --- |
|
|
| Offered surface | Provider Modeling and local Mind | Current Body basis and semantic offer intent | `gamecult.model.surface_offer.v0` |
|
|
| Dependency claim | Consumer Modeling and local Mind | Current Body basis and semantic claim intent | `gamecult.model.dependency_claim.v0` |
|
|
| Edge verification | Consumer Soul and local Mind | Exact signed claim/offer versions and exact evidence artifact | `gamecult.model.dependency_verification.v0` |
|
|
| Publication | Repository publisher | Only its local Mind documents and exact Mind receipts | Signed `gamecult.model.atlas_publication.v0` events |
|
|
| Discovery and transport | Odin | Registered typed records | Opaque persisted/queryable publications and projections |
|
|
| Join, compatibility, cycles, blast radius | Atlas projector | Signed publications visible to one trusted audience | `gamecult.model.entanglement_projection.v0` |
|
|
| Local impact | Consumer Self and local Mind | Exact local claim plus exact projection/source set | `epiphany.model.dependency_impact.v0` |
|
|
| Lane wake | Consumer Resident Self | Admitted local impact and local lane lifecycle | Modeling or Soul pressure with no Hands grant |
|
|
| Presentation | Eve | One provider-owned retained tree | GUI and TUI lowerings of the same projection |
|
|
|
|
Nobody owns a shared edge. The projector derives each edge from a
|
|
provider-owned offer and a consumer-owned claim. Odin stores and serves those
|
|
facts but cannot normalize them into dependency truth. Eve renders them but
|
|
cannot mutate them.
|
|
|
|
## Data flow
|
|
|
|
```text
|
|
provider Mind offer -------+ +--> Eve retained tree
|
|
| |
|
|
consumer Mind claim -------+--> signed publication --> Odin --> projector
|
|
| |
|
|
consumer Soul verification + v
|
|
signed projection
|
|
|
|
|
consumer impact ingress
|
|
|
|
|
local Mind impact CAS
|
|
|
|
|
local Resident Self wake
|
|
```
|
|
|
|
No organ opens another repository's Mind store. Publishers read only their own
|
|
runtime Mind store. The projector reads Odin. Impact ingress reads the
|
|
projection plus its own local claims.
|
|
|
|
## Modeling authoring and Body evidence
|
|
|
|
Ordinary Modeling is the sole production authoring path for offers and claims.
|
|
Its model output names only semantic operations: create, deprecate, withdraw,
|
|
or retire. Creation includes a human label, a closed contract shape, and a
|
|
non-empty sorted set of repository-relative source paths. It cannot supply
|
|
UUIDs, source digests, causal identifiers, Body bases, CAS reads, timestamps,
|
|
receipts, or writes.
|
|
|
|
The runtime constructs `epiphany.repo_model.mutation_proposal.v2` from the
|
|
exact worker request, exact result, ordered evidence identifiers, and the Body
|
|
basis sealed into the launch. The keyed planner re-reads the current Body
|
|
basis, authenticates the manifest, resolves every requested source path to its
|
|
raw SHA-256, derives opaque UUIDv5 identities, and produces the exact Mind CAS.
|
|
An old Body observation or changed source refuses before any document is
|
|
written.
|
|
|
|
The publisher repeats the Body check at the federation boundary. It refuses to
|
|
publish an offer or claim unless every stored source path and digest still
|
|
matches the current authenticated Body manifest. The projector retains those
|
|
endpoint labels, contracts, lifecycle states, and Body references alongside
|
|
the exact applicable Soul evidence. Eve can therefore show why an edge exists,
|
|
not merely that the projector drew one.
|
|
|
|
## Invariants
|
|
|
|
- Repository identity is
|
|
`gamecult://swarm/{swarm_id}/workspace/{workspace_id}`. Runtime and Body
|
|
incarnation are evidence, not stable identity.
|
|
- Surface and claim identity are opaque UUIDs. Labels and paths cannot own
|
|
identity.
|
|
- Contract compatibility is closed: SemVer, exact schema ID, or exact SHA-256
|
|
digest. Scheme mismatch is incompatible. Natural language has no vote.
|
|
- The real repository Body digest is canonical 64-character lowercase SHA-256
|
|
hex. Atlas publication digests use the explicit `sha256-` transport form.
|
|
These are deliberately separate wire contracts.
|
|
- A source-version digest seals the exact compact MessagePack bytes in the
|
|
owning CultCache record. `canonicalPayloadMsgpackSha256` separately seals the
|
|
named canonical MessagePack published across the federation. Neither digest
|
|
may substitute for the other.
|
|
- Local offer, claim, verification, and impact writes use dedicated typed
|
|
planners and exact CultCache CAS. A stale Body or source version refuses the
|
|
entire mutation.
|
|
- Model-authored offer and claim operations contain semantic intent and source
|
|
paths only. Runtime-owned proposal v2 binds exact cause, evidence, current
|
|
Body basis, resolved source digests, derived identities, and CAS authority.
|
|
- Publications bind repository, runtime incarnation, Body basis, Verse,
|
|
source schema/key/version/digest, Mind receipt, canonical payload digest,
|
|
publication time, and service signature.
|
|
- Publisher status is emitted every 30 seconds and becomes stale after 90
|
|
seconds. A partition retains last-known edges and marks them unknown; absence
|
|
never impersonates safety.
|
|
- Verification applies only to the exact current claim and offer versions.
|
|
- Build, deployment, and infrastructure-control cycles are blocked. Runtime,
|
|
data, and schema cycles require declared failure semantics, remain
|
|
review-required, and do not propagate autonomously. Informational
|
|
governance/lore/persona cycles remain visible.
|
|
- Atlas may wake Modeling or Soul. Every pressure carries the explicit clause
|
|
`This wake grants no Hands authority.`
|
|
- `atlas.publish`, `atlas.project`, and `atlas.impact_ingress` brakes stop writes
|
|
and scheduling while retaining the last projection read-only.
|
|
|
|
## Live organs
|
|
|
|
- `epiphany-atlas-publisher` reads a local Mind store, publishes immutable
|
|
events to its publisher CultCache/CultMesh store, and transports them to
|
|
Odin. Its signing identity lives in a separate private `.cc` store.
|
|
- `epiphany-model-entanglement-projector` pins repository trust anchors, queries
|
|
Odin, verifies publications, derives a deterministic projection, and
|
|
publishes the canonical Eve provider and surface documents.
|
|
- `epiphany-atlas-impact-ingress` compares a projection with locally owned
|
|
claims, admits exact impact documents, and asks local Resident Self to
|
|
schedule permitted pressure.
|
|
|
|
Each organ has its own store. The local Mind, private identity, publisher
|
|
events, CultMesh publication, Odin catalog, projection, and impact scheduler
|
|
state are never collapsed into a writable mega-graph.
|
|
|
|
## Starfire pilot topology
|
|
|
|
The pilot uses three independent repository identities and state roots:
|
|
|
|
| Repository Body | Repository identity | Locally owned Atlas facts |
|
|
| --- | --- | --- |
|
|
| `F:\Projects\Eve` | one Starfire Eve workspace identity | Offers `gamecult.eve.surface.v1` |
|
|
| `F:\Projects\Odin` | one Starfire Odin workspace identity | Claims Eve surface; offers `cultmesh://odin/rendezvous/provider-catalog` |
|
|
| `F:\Projects\Epiphany` | one Starfire Epiphany workspace identity | Claims Odin provider catalog |
|
|
|
|
The Odin claim marks its catalog offer as affected. The projector therefore
|
|
derives `Epiphany -> Odin`, `Odin -> Eve`, and Epiphany's two-hop blast-radius
|
|
membership when Eve changes.
|
|
|
|
Do not invent deterministic IDs from repository paths. Each local Modeling
|
|
organ creates and retains its opaque surface and claim UUIDs. Trust anchors are
|
|
pinned by exact repository coordinates; key rotation is operator-gated.
|
|
|
|
## Rollout gates
|
|
|
|
1. Keep impact ingress absent. Let ordinary Modeling admit the three local seed
|
|
facts into isolated Mind stores, then run the publishers and projector until
|
|
signed publications, exact watermarks, and the retained Eve tree exist.
|
|
Engage `atlas.publish`, `atlas.project`, and `atlas.impact_ingress`, run one
|
|
more publisher/projector cycle plus the first ingress cycle, and prove every
|
|
write/schedule is held while the last projection remains visibly stale and
|
|
read-only. A brake cannot both forbid the first publication and prove that a
|
|
publication exists; ordering is part of the invariant.
|
|
2. Release Atlas scopes for Modeling and Soul while leaving existing Hands
|
|
authorization unchanged. A temporary Eve contract change must wake Odin
|
|
Modeling and then Epiphany Modeling without an operator prompt.
|
|
3. Place the organs under the existing daemon supervisor. Sustain the pilot
|
|
while observing publisher/projector lag, per-publisher watermarks,
|
|
rejection count, cycles, and pending impacts through CultMesh/Eve.
|
|
4. Only after sustained local proof, register topology and recovery runbooks in
|
|
`gamecult-ops`. Yggdrasil and the public Verse remain outside V1.
|
|
|
|
The implementation and isolated proofs close the code slice. All four rollout
|
|
gates are operational evidence, not claims that can be manufactured by unit
|
|
tests.
|
|
|
|
## Verification
|
|
|
|
The focused proofs cover:
|
|
|
|
- no production `RepoModelPatch`, aggregate RepoModel store, aggregate
|
|
admission reader/writer, or aggregate memory-graph key;
|
|
- runtime-owned proposal-v2 construction from exact request, result, evidence,
|
|
and launch Body basis; models provide semantic operations only;
|
|
- local offer/claim admission through current authenticated Body manifests,
|
|
resolved source digests, derived UUIDs, exact reasoning bases, and Mind CAS;
|
|
- publisher refusal after local Body evidence drifts;
|
|
- signature tamper, trust-coordinate substitution, rollback, replay,
|
|
watermark, and payload-size refusal;
|
|
- order-independent projection digests, closed compatibility, verification
|
|
invalidation, visibility-before-join, cycle classes, partition staleness, and
|
|
deterministic transitive blast radius;
|
|
- the exact Epiphany -> Odin -> Eve chain and direct/transitive Modeling
|
|
pressure after an Eve schema change;
|
|
- impact dedupe, pending lane locks, cooldown after completion, brake behavior,
|
|
informational visibility without wake, and absence of Hands authority;
|
|
- Odin persistence of only the registered Atlas/projection/Eve schemas without
|
|
Odin-authored edges;
|
|
- Eve conformance for one canonical GUI/TUI tree with endpoint contracts,
|
|
source evidence, exact Soul evidence, publisher age/watermarks, cycles, blast
|
|
radius, and presentation-only select/filter commands.
|
|
|
|
Current counts are Epiphany core 555/555, OpenAI Modeling ingress 23/23,
|
|
coordinator 18/18, Odin Node 1/1 plus Rust 15/15, and Eve Atlas 4/4 plus Eve
|
|
contracts 6/6. The ordinary Epiphany all-target workspace check also passes.
|
|
|
|
Current verification commands:
|
|
|
|
```powershell
|
|
$env:CARGO_TARGET_DIR='C:\Users\Meta\.cargo-target-codex'
|
|
cargo test -p epiphany-core --lib
|
|
cargo test -p epiphany-openai-runtime --lib
|
|
cargo test -p epiphany-release-bundle --features coordinator-runtime --bin epiphany-mvp-coordinator
|
|
cargo check --workspace --all-targets
|
|
|
|
Set-Location F:\Projects\Odin
|
|
node --test test/model-atlas-documents.test.cjs
|
|
cargo test -p odin-core
|
|
|
|
Set-Location F:\Projects\Eve
|
|
node --test web/model-atlas-conformance.test.mjs
|
|
node --test packages/eve-contracts/test/contracts.test.mjs
|
|
```
|
|
|
|
`cargo check --workspace --all-targets --all-features` still reaches the older
|
|
feature-gated `epiphany-workspace-coverage-recovery-smoke`, which imports
|
|
`current_workspace_coverage_recovery_target` and
|
|
`WorkspaceCoverageRecoveryTarget`; those symbols were already absent before
|
|
this slice. Do not restore them as an Atlas compatibility shim. The ordinary
|
|
all-target workspace and all Atlas-bearing targets compile.
