feat(server): rfc 0048 slice 2 — graph identity keys are configuration - #715
Conversation
visibility.identities.user_columns / agent_columns name the promoted columns whose values become user:/agent: principals in the emitter's tuples; unset lists take the semconv defaults (attr.user.hash + attr.enduser.pseudo.id / attr.gen_ai.agent.id — verified current against the OTel registry), so a deployment that says nothing gets the same graph. Explicit empty or duplicated lists are refused naming the key; self_principal_column must be one of user_columns; every graph-bound column (object, identity, self) must be in the effective promoted set — a startup error, not an empty graph. Scenario RFC0048.3. Signed-off-by: Jens Holdgaard Pedersen <Jens@holdgaard.org>

📝 WalkthroughWalkthroughOpenFGA visibility now supports configurable user and agent identity columns. The server parses and validates these mappings, applies RFC 0048 defaults, and passes them to graph emission. Graph identities can come from log or resource attributes. ChangesOpenFGA identity column configuration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Partial identity configuration can currently reject valid deployments at startup because the unset identity list is still validated against its defaults; the documentation also needs clearer validation guidance. The PR should not merge until the validation behavior is corrected and the documentation is built and verified. Sequence Diagram(s)sequenceDiagram

Pull request overview
Implements RFC 0048 slice 2 by making OpenFGA graph identity keys configurable, while preserving the existing tuple-derivation semantics and introducing fail-closed startup validation when graph-bound columns aren’t in the effective promoted set.
Changes:
- Adds
visibility.identities.{user_columns,agent_columns}configuration (with semconv defaults) and wires it through server config → core OpenFGA config → ingester graph emitter. - Introduces startup validation ensuring object/identity/self columns are in the effective promoted set, producing key-named errors instead of silently yielding an empty graph.
- Updates docs and expands tests to cover identity configuration, substitution, and startup error arms.

…s only The semconv defaults are the RFC 0047 constants and never required promotion (the emitter reads record attributes, not the projection); enforcing the check on a defaulted list made every deployment that does not promote enduser.pseudo.id / gen_ai.agent.id fail startup — the container suite included. identities_configured on VisibilityConfig scopes the check to operator-listed columns (RFC 0048 §3.2 'every listed column').

- The configuration example now implies identities columns must be ‘promoted columns’, but it doesn’t mention that these also need to be present in storage.promoted_attributes (otherwise the server will fail startup once OpenFGA visibility is enabled). Adding an explicit note here would prevent a confusing misconfiguration for operators.
# Optional (RFC 0048 §3.2). Which promoted columns carry the

identities_configured()is a single boolean (true if eitheruser_columnsoragent_columnswas explicitly set), butvalidate_graph_columns()uses it to gate validation of bothvisibility.user_columns()andvisibility.agent_columns(). This means a partial configuration (e.g. operator sets onlyuser_columnsand leavesagent_columnsunset) will still require the default agent identity columns to be present instorage.promoted_attributes, contradicting the stated rule that defaulted identity lists are exempt from the promoted-set startup check.
if visibility.identities_configured() {
for column in visibility.user_columns() {
check("identities.user_columns", column)?;
}
for column in visibility.agent_columns() {
check("identities.agent_columns", column)?;

- Around line 620-623: Update the identity configuration state near
validate_graph_columns to track user_columns and agent_columns independently
instead of using one combined identities_configured flag. Ensure partial
overrides validate only the explicitly configured identity list while preserving
defaults for the other list, and add regression coverage for user-only and
agent-only configurations.
In `@docs/guides/configuration.md`:
- Around line 86-92: Update the identities configuration documentation to
clarify that omitted user_columns and agent_columns use semconv defaults and are
exempt from promoted-column validation, while explicitly configured entries must
be promoted columns; document that self_principal_column, when set, must be
promoted and included in user_columns. Build the documentation with mdbook build

- The configuration guide describes defaults and the promoted-column requirement, but it doesn’t mention that explicitly empty
identities.*_columnslists (and duplicates) are rejected. Without this, an operator may reasonably tryuser_columns: []to disable principals and only learn via a startup error.
Consider documenting the "empty list is invalid; omit for defaults" and "duplicates are invalid" rules alongside the existing comment.
# principals in a conversation. An omitted list takes the semconv
# default shown here and is exempt from the promoted-column check;
# every EXPLICITLY listed entry must be a promoted column (startup
# error otherwise). self_principal_column, when set, must be a
# promoted column AND one of user_columns.
Summary
RFC 0048 implementation, slice 2: identity keys as configuration (§3.2) — RFC0048.3.
visibility.identities.user_columns/agent_columnsname the promoted columns whose values becomeuser:/agent:principals in the emitter's tuples (participant + binding, actor + binding, unchanged mechanics). Unset lists take the semconv defaults —attr.user.hash,attr.enduser.pseudo.id/attr.gen_ai.agent.id, verified current against the OTel registry via the docs MCP — so a deployment that says nothing gets the same graph (RFC0047.10 unchanged).self_principal_columnmust be one ofuser_columns,self_principal_columnmust be one ofuser_columns, and the object, self and every operator-listed identity column must be in the effective promoted set — a startup error, not an empty graph (defaulted lists are exempt: the RFC 0047 constants never required promotion).USER_KEYS/AGENT_KEYconstants are gone; identity columns parse into the same log/resource column-key form as the conversation column (aresource.-family identity column reads resource attributes).identitiesblock with${env:…}substitution; documented in the configuration guide.Invariants / hazards
Hazard #1-adjacent (graph correctness): derivation semantics are unchanged — only which columns feed it becomes explicit configuration with the previous constants as defaults. Fail-closed posture preserved: misconfiguration is a startup error; off-object-id values are skipped exactly as before.
