ontoref-derive: #[onto_mcp_tool] attribute macro registers MCP tool unit-structs in
the catalog at link time via inventory::submit!; annotated item is emitted unchanged,
ToolBase/AsyncTool impls stay on the struct. All 34 tools migrated from manual wiring
(net +5: ontoref_list_projects, ontoref_search, ontoref_describe,
ontoref_list_ontology_extensions, ontoref_get_ontology_extension).
validate modes (ADR-018): reads level_hierarchy from workflow.ncl and checks every
.ncl mode for level declared, strategy declared, delegate chain coherent, compose
extends valid. mode resolve <id> shows which hierarchy level handles a mode and why.
--self-test generates synthetic fixtures in a temp dir for CI smoke-testing.
validate run-cargo: two-step Cargo.toml resolution — workspace layout first
(crates/<check.crate>/Cargo.toml), single-crate fallback by package name or repo
basename. Lets the same ADR constraint shape apply to workspace and single-crate repos.
ontology/schemas/manifest.ncl: registry_topology_type contract — multi-registry
coordination, push targets, participant scopes, per-namespace capability.
reflection/requirements/base.ncl: oras ≥1.2.0, cosign ≥2.0.0, sops ≥3.9.0, age
≥1.1.0, restic declared as Hard/Soft requirements with version_min, check_cmd, and
install_hint (ADR-017 toolchain surface).
ADR-019: per-file recipient routing for tenant isolation without multi-vault. Schema
additions: sops.recipient_groups + sops.recipient_rules in ontoref-project.ncl.
secrets-bootstrap generates .sops.yaml from project.ncl in declarative mode. Three
new secrets-audit checks: recipient-routing-coherent, recipient-routing-coverage,
no-multi-vault. Adoption templates: single-team/, multi-tenant/, agent-first/.
Integration templates: domain-producer/, mode-producer/, mode-consumer/.
UI: project_picker surfaces registry badge (⟳ participant) and vault badge
(⛁ vault_id · N, green=declarative / amber=legacy) per project card. Expanded panel
adds collapsible Registry section with namespace, endpoint, and push/pull capability.
manage.html gains Runtime Services card — MCP and GraphQL toggleable without restart
via HTMX POST /ui/manage/services/{service}/toggle.
describe.nu: capabilities JSON includes registry_topology and vault_state per project.
sync.nu: drift check extended to detect //! absence on newly registered crates.
qa.ncl: six entries — credential-vault-best-practice (layered data-flow diagram),
credential-vault-templates (paths A/B/C), credential-vault-troubleshooting (15 named
errors), integration-what-and-why (ADR-042 OCI federation), integration-how-to-implement,
integration-troubleshooting.
on+re: core.ncl + manifest.ncl updated to reflect OCI, MCP, and mode-hierarchy nodes.
Deleted stale presentation assets (2026-02 slides + voice notes).

ontoref is a protocol specification and tooling layer for structured self-knowledge in software projects. It provides schemas, Nushell automation, and Rust crates so that projects can describe what they are, record architectural decisions, track operational state, and execute formalized procedures — all as typed, queryable artifacts.
Axioms
| Axiom | Meaning |
|---|---|
| Protocol, Not Runtime | Never a runtime dependency. Projects adopt the protocol; ontoref provides the schemas and modules to do so. |
| Self-Describing | Consumes its own protocol: .ontology/, adrs/, reflection/ in this repo ARE ontoref running against itself. |
| No Enforcement | ontoref defines contracts. There is no enforcement mechanism. Coherence is voluntary and emerges from justified adoption. |
| DAG-Formalized Knowledge | Concepts, tensions, decisions, state — encoded as DAGs. Enables transversal queries and impact analysis. |
Layers
ontology/ Protocol specification — Nickel schemas for nodes, edges, ADRs, state, gates
adrs/ Architecture Decision Records — typed NCL with constraints and ontology checks
reflection/ Operational tooling — Nushell modules, DAG modes, forms, and schemas
crates/ Rust implementation — typed struct loaders and mode executors
.ontology/ Self-description — ontoref's own ontology, state, gate, and manifest
Crates
| Crate | Purpose |
|---|---|
ontoref-ontology |
.ontology/ NCL → typed Rust structs: Node, Edge, Dimension, Gate, Membrane. Node carries artifact_paths and adrs (Vec<String>, both serde(default)). Graph traversal, invariant queries. Zero deps. |
ontoref-reflection |
NCL DAG contract executor with guards (pre-flight Block/Warn checks) and convergence loops (RetryFailed/RetryAll). ADR lifecycle, step dep resolution, config seal. stratum-graph + stratum-state required. |
ontoref-daemon |
HTTP UI (11 pages), actor registry, notification barrier, MCP (34 tools), search engine, search bookmarks, SurrealDB, NCL export cache, per-file ontology versioning, annotated API catalog, Agent Task Composer. |
ontoref-derive |
Proc-macro crate. #[onto_api(...)] annotates HTTP handlers — description is optional when a /// doc comment exists (first line used as fallback). #[onto_mcp_tool(name, description, input_schema)] registers MCP tool unit-structs in the catalog at link time via inventory::submit!(McpToolEntry{...}); the annotated item is emitted unchanged and ToolBase/AsyncTool impls remain on the struct. #[derive(OntologyNode)] + #[onto(id, name, paths, description, adrs)] auto-registers nodes via inventory::submit! at link time, merged into Core by merge_contributors(). #[derive(ConfigFields)] + #[config_section(id, ncl_file)] registers config struct fields. All four aggregate via inventory::collect!. |
ontoref-daemon caches nickel export results (keyed by path + mtime), reducing full sync
scans from ~2m42s to <30s. The daemon is always optional — every module falls back to direct
subprocess when unavailable.
Daemon Capabilities
Unified Auth Model — all surfaces (CLI, UI, MCP) exchange a key for a UUID v4 session token
via POST /sessions. Token lifetime: 30 days, O(1) lookup. Project keys carry role
(admin|viewer) and label for audit trail. Daemon-level admin via ONTOREF_ADMIN_TOKEN_FILE.
GET /sessions and DELETE /sessions/{id} for session visibility and revocation. Key rotation
invalidates all sessions for the rotated project. CLI injects ONTOREF_TOKEN as Bearer
automatically.
Q&A Knowledge Store — accumulated Q&A entries persist to reflection/qa.ncl (typed NCL,
git-versioned). Not localStorage. Any actor — developer, agent, CI — reads the same store.
MCP Server — 34 tools over stdio and streamable-HTTP, all registered at link time via
#[onto_mcp_tool] (no manual catalog wiring). Categories: discovery, retrieval, project
state, ontology, backlog, validation, Q&A, bookmarks, API surface. Representative subset:
| Tool | What it does |
|---|---|
ontoref_guides |
Full project context on cold start: axioms, practices, gate, actor policy |
ontoref_api_catalog |
Annotated HTTP surface — all routes with auth, actors, params, tags |
ontoref_file_versions |
Per-file reload counters — detect which ontology files changed |
ontoref_validate_adrs |
Run typed ADR constraint checks; returns pass/fail per constraint |
ontoref_validate |
Full project validation: ADRs, content assets, connections, gate consistency, manifest coverage |
ontoref_impact |
BFS impact graph from a node, optionally across project connections |
ontoref_qa_list |
List Q&A entries with optional filter |
ontoref_qa_add |
Append a new Q&A entry to reflection/qa.ncl |
ontoref_action_list |
List quick actions from .ontoref/config.ncl |
ontoref_action_add |
Create a reflection mode + register as a quick action |
Search Bookmarks — search results persist to reflection/search_bookmarks.ncl (typed NCL,
BookmarkEntry schema). Same atomic-write pattern as Q&A. IDs are sequential sb-NNN.
Concurrency-safe via NclWriteLock. Add and remove from the daemon search UI.
Personal Ontology Schemas — ontology/schemas/career.ncl, personal.ncl, project-card.ncl
provide typed contract layers for career and content artifacts (Skills, WorkExperience, Talks,
Content lifecycle, Opportunities, PublicationCards). All types carry linked_nodes referencing
core ontology node IDs — bridging career artifacts into the DAG. Five content/career reflection
modes (draft-application, draft-email, generate-article, update-cv, write-cfp) query
these schemas to ground output in declared project artifacts rather than free-form prose.
API Catalog — every HTTP handler carries #[onto_api(method, path, auth, actors, params, tags)].
description is sourced from the first /// doc line above the handler — no duplication with doc comments.
At link time inventory::submit! registers each route. GET /api/catalog returns the full annotated
surface as JSON. The /ui/{slug}/api page renders it with client-side filtering (method, auth, path).
describe api [--actor] [--tag] [--fmt] renders the catalog in the CLI. ontoref_api_catalog exposes
it to MCP agents.
Semantic Diff — describe diff [--file <ncl>] [--fmt json|text] computes a node- and edge-level
diff of .ontology/ files against the last git commit. Reports added/removed/changed nodes by id and
edges by from→to[kind] key — not a text diff.
Per-File Versioning — each ontology file tracked in ProjectContext.file_versions: DashMap<PathBuf, u64>.
Counter increments on every watcher-triggered reload. GET /projects/{slug}/ontology/versions and
ontoref_file_versions MCP tool expose the map. Dashboard surfaces the counters.
ADR–Node Linkage — nodes declare which ADRs validate them via adrs: Array String.
describe surfaces a Validated by section per node (CLI and --fmt md). The graph UI
renders each ADR as a clickable link that opens the full ADR content via GET /api/adr/{id}.
Browser-Style Panel Navigation — graph, search, and api_catalog UI pages carry a
back/forward history stack (cursor-into-array model). Clicking nodes, ADRs, or search results
pushes to history; clicking artifacts opens the source file in the configured repository or
docs. card.repo in card.ncl resolves to {repo}/src/branch/main/{path} (Gitea format).
For .rs files, card.docs redirects to the cargo docs URL instead. insert_brand_ctx
injects both as card_repo/card_docs into every Tera template.
Passive Drift Observation — background file watcher that detects divergence between Yang
code artifacts and Yin ontology. Watches crates/, .ontology/, adrs/, reflection/modes/.
After a 15s debounce runs sync scan + sync diff; emits an ontology_drift notification when
MISSING/STALE/DRIFT/BROKEN items are found. Never applies changes — apply is always deliberate.
Quick Actions — runnable shortcuts over reflection modes, configured as quick_actions in
.ontoref/config.ncl. Accessible from HTTP (/actions), CLI (ontoref), and MCP
(ontoref_action_list/add).
Config Surface — per-project config introspection, coherence verification, and documented
mutation. Rust structs annotated with #[derive(ConfigFields)] + #[config_section(id, ncl_file)]
register their field names at link time via inventory::submit!(ConfigFieldsEntry{...}). The daemon
queries inventory::iter::<ConfigFieldsEntry>() at startup to build a zero-maintenance registry of
which Rust fields each struct reads from each NCL section. Multi-consumer coherence
(GET /projects/{slug}/config/coherence) compares the inventory registry against NCL export keys,
Nu script accessor patterns, and CI fields declared in manifest.ncl — any NCL field claimed by no
consumer is flagged unclaimed. GET /projects/{slug}/config/quickref generates living documentation
(rationales, override history, coherence status) on demand.
Config mutation never modifies source NCL files. PUT /projects/{slug}/config/{section} writes a
{section}.overrides.ncl file with only the changed fields plus a _overrides_meta audit record
(actor, reason, timestamp, previous value), then appends a single idempotent import line to the
entry-point NCL using the & merge operator. nickel export validates the merged result against the
section's declared contract before committing; contract violations revert the override file and return
the nickel error verbatim. NCL contracts (std.contract.from_validator) are the single validation
gate — Rust structs are contract-trusted readers with #[serde(default)].
Ontoref demonstrates the pattern on itself: .ontoref/contracts.ncl applies LogConfig and
DaemonConfig contracts to .ontoref/config.ncl. (ADR-008)
Protocol Migration System — protocol upgrades for consumer projects expressed as ordered NCL files
in reflection/migrations/NNN-slug.ncl. Each migration declares a typed check (FileExists | Grep | NuCmd) whose result IS the applied state — no state file, fully idempotent. migrate list shows all
migrations with applied/pending status; migrate pending lists only what is missing; migrate show <id>
renders runtime-interpolated instructions (project_root and project_name auto-detected). NuCmd checks are
valid Nushell (no bash &&, $env.VAR not $VAR). Grep checks targeting ADR files scope to
adr-[0-9][0-9][0-9]-*.ncl to exclude schema/template infrastructure files. 12 migrations shipped;
0012-rust-doc-authoring-pattern adds the /// → //! → node description three-layer doc convention
and optional pre-commit hooks (docs-links, docs-drift) to consumer CLAUDE.md. (ADR-010)
Manifest Self-Interrogation — manifest_type gains three typed arrays that answer self-knowledge
queries agents and operators need on cold start: capabilities[] (what the project does, why it was
built, how it works — with explicit nodes[] and adrs[] cross-references into the DAG),
requirements[] (prerequisites classified by environment: 'Production | 'Development | 'Both and
kind: 'Tool | 'Service | 'EnvVar | 'Infrastructure), critical_deps[] (external dependencies with
required failure_impact and optional mitigation). describe requirements surfaces these; describe guides and ontoref_guides include all three arrays in their output. (ADR-009)
Domain Extension System — CLI commands conditional on repo_kind. The ontoref bash wrapper
resolves the first argument against $ONTOREF_ROOT/domains/{id}/repo_kinds.txt before delegating to
the Nu dispatcher; if the project's repo_kind matches, the domain's commands.nu is dispatched
directly. Each domain ships domain.ncl (typed contract: commands, pages, short_alias, repo_kinds),
commands.nu (Nu entry point), and repo_kinds.txt (grep-readable, sub-1ms dispatch). Two domains
shipped: personal (PersonalOntology — cfp, career, content, opportunities) and provisioning
(DevWorkspace/Mixed — state, connections, gates, card, backlog). Short aliases (personal, prov)
work as both ore prov <cmd> and standalone prov <cmd>. ore help and describe capabilities
surface the active domain automatically. New domains require only three files — no changes to the Nu
dispatcher. (ADR-012)
Mode Hierarchy Validation — validate modes [--check] reads reflection/defaults/workflow.ncl::level_hierarchy
and checks every .ncl mode file for: level declared, strategy declared, delegate chain coherent,
compose extends references valid. mode resolve <id> prints which hierarchy level handles the
given mode and why. validate modes --self-test generates synthetic fixtures in a temp dir for
fast CI smoke-testing of the validator itself. (ADR-018)
Project Picker — vault and registry badges — each project card surfaces OCI state inline:
registry participant badge (⟳ <participant>) when registry_provides is declared; vault badge
(⛁ <vault_id> · N) coloured green (declarative) or amber (legacy) when sops.enabled is true.
Expanded project panel shows a collapsible Registry section with namespace, endpoint, and
push/pull capability. The manage page adds Runtime Services toggles — MCP and GraphQL can be
switched without a daemon restart via HTMX POST /ui/manage/services/{service}/toggle.
VCS Abstraction Layer — reflection/modules/vcs.nu exposes a uniform API over jj and git:
detect, show-committed, restore-file, remote-url, current-branch, uncommitted-files,
commit-count. All ontoref modules consume vcs.nu — never hardcoded ^git. Detection is
filesystem-based (.jj/ vs .git/), no config required. jj is opt-in: all operations degrade to
git when .jj/ is absent. reflection/bin/jjw.nu wraps jj workspaces, ontoref runs, and optional
Radicle patch submission into a single jjw agent create|step|publish|merge|discard lifecycle for
agent-driven development. jjw-ncl-merge.nu is a jj merge tool for .ontology/ NCL conflicts,
registered manually in ~/.config/jj/config.toml. jj and Radicle are not protocol requirements —
consumer projects use plain git without any configuration change.
Install
just install-daemon # build + install binary, bootstrapper, CLI, UI assets, config skeleton
ontoref config-edit # browser form → ~/.config/ontoref/config.ncl
ontoref-daemon-boot # NCL pipe bootstrap: nickel export config.ncl | daemon --config-stdin
ontoref-daemon-boot --dry-run # preview composed JSON without starting
Installed layout (~/.local/bin/):
| Binary | Role |
|---|---|
ontoref |
Global CLI dispatcher — all reflection modes, ADR lifecycle, daemon control |
ontoref-daemon |
Bootstrapper (public entrypoint) — validates config via Nickel, pipes JSON to binary |
ontoref-daemon.bin |
Compiled Rust binary — never called directly |
Global config at ~/.config/ontoref/config.ncl (type-checked Nickel). Global NATS stream topology at
~/.config/ontoref/streams.json. Project-local topology override via nats/streams.json +
nats_events.streams_config in .ontoref/config.ncl.
Onboarding a project
cd /path/to/my-project
ontoref setup # idempotent; kind: Service by default
ontoref setup --kind Library # Library | Service | DevWorkspace | PublishedCrate | AgentResource | Mixed | PersonalOntology
ontoref setup --parent /path/to/fw # implementation child: adds framework layer + browse mode
ontoref setup --gen-keys ["admin:dev" "viewer:ci"] # bootstrap auth keys (no-op if keys already exist)
ontoref setup creates .ontoref/project.ncl, .ontoref/config.ncl (with logo auto-detection),
.ontology/ scaffold, adrs/, reflection/modes/, backlog.ncl, qa.ncl, git hooks, and
registers the project in ~/.config/ontoref/projects.ncl.
For existing projects that predate setup, or to bring an already-adopted project up to the
current protocol version (adds manifest.ncl and connections.ncl):
ontoref --actor developer adopt_ontoref # first-time adoption
ontoref run update_ontoref # bring existing project to protocol v2
The update_ontoref mode detects missing v2 files, adds them idempotently, validates both with
nickel export, scans ADRs for deprecated check_hint fields, and prints a protocol update
report. The reusable reflection/templates/update-ontology-prompt.md guides an agent through
full ontology enrichment in 8 phases.
ONTOREF_PROJECT_ROOT is set by the consumer wrapper — one ontoref checkout serves multiple projects.
Credential vault and registry federation
ontoref ships a credential model for projects publishing or consuming OCI artifacts (domain contracts and integration modes) on a self-hosted registry like ZOT. The model is layered, declarative, and avoids ambient docker config:
- Layer 0 — master age private key (
.kage) per actor, declared in~/.config/ontoref/config.ncl::vault.master_key_path(override per-project in<project>/.ontoref/project.ncl::sops.master_key_path) - Layer 1 —
access.sops.yamlper project, multi-recipient encrypted; carrieszot_username,zot_password,vault_key,cosign_password - Layer 2 — operation credentials (RO/RW per registry entry) under
src-vault/registry/, referenced bymanifest.ncl::registry_provides[].credential_sops*
Tenant isolation within a single vault uses sops creation_rules driven by
sops.recipient_groups + sops.recipient_rules in project.ncl — different
clients/agents get disjoint recipient sets per file, all in one vault. Multi-vault
is explicitly out of scope (ADR-019).
Adoption — copy a template from install/resources/templates/sops/:
| Template | When to use |
|---|---|
single-team/ |
One team, no tenant separation |
multi-tenant/ |
Multiple clients with isolated credentials |
agent-first/ |
AI agents (MCP) read a single read-only credential |
For integration artifacts (publishing domain contracts or consuming someone's mode),
templates in install/resources/templates/integration/: domain-producer/,
mode-producer/, mode-consumer/.
Day-to-day:
ore secrets bootstrap # create vault for a new project (admin only)
ore secrets sync # pull latest src-vault from ZOT
ore secrets open # acquire OCI lock + edit access.sops.yaml
ore secrets close # impact report → push → release lock
ore secrets describe # full inventory: groups, rules, scopes, ops
ore secrets audit # 6 ADR-017 + ADR-019 constraint checks
See FAQ entries in reflection/qa.ncl for diagrams, troubleshooting, and the
15 named errors. ADRs: 017
(vault model) and 019
(per-file recipient routing).
Prerequisites
- Nushell >= 0.110.0
- Nickel (for schema evaluation)
- Rust toolchain (for building crates)
- Just (for CI recipes)
- age + sops (credential vault, ADR-017/019)
- oras + cosign ≥ 2 (OCI artifact federation)
- restic or kopia (vault snapshots)
To build ontoref-daemon and ontoref-reflection with NATS/SurrealDB support, the
stratumiops repo must be checked out at ../../../stratumiops. Without it, build without
default features:
cargo build -p ontoref-daemon --no-default-features
cargo build -p ontoref-ontology # always standalone
Development
cargo check-all # check all targets + features
cargo test-all # run full test suite
just ci-lint # clippy + TOML + Nickel + Markdown
just ci-docs # rustdoc broken intra-doc link check
just ci-full # all CI checks
nu --ide-check 50 reflection/modules/<file>.nu # validate a Nushell module
./ontoref --actor developer <mode> # run a reflection mode
./ontoref sync diff --docs # crate //! drift against ontology nodes
./ontoref describe workspace # per-crate doc coverage + drift status
Doc authoring convention
Three canonical layers — no duplication across them:
| Layer | Where | Read by |
|---|---|---|
/// first line |
handlers, structs, types | #[onto_api], #[derive(OntologyNode)], MCP |
//! first sentence |
lib.rs |
describe features, mdBook crates chapter, drift check |
node description |
.ontology/core.ncl |
UI graph, describe project, CLI |
sync diff --docs --fail-on-drift (used by pre-commit docs-drift hook) enforces that //! first
sentence stays aligned with the practice node description (Jaccard ≥ 0.20 threshold).
