feat(auth): rfc 0047 slice 2 — planner two-step + visibility (RFC0047.4–.8) - #706
Merged
Conversation
auth.openfga.visibility (objects[type,column] — conversation only in v1, self_principal_column, content_columns with the GenAI default set, max_objects, list_timeout_ms strictly below server_list_objects_deadline_ms) and OpenFgaResolver::visibility: Check(can_read_content) → TenantWide, Check(can_read_metadata) → MetadataOnly, else the streamed enumeration filtered to the tenant prefix, counting only tenant ids toward the bound (BoundExceeded / Incomplete fail closed, never cached); the two checks cache with the session TTL. Principal ids are validated as object ids (InvalidPrincipal, 401-class). Fake-backed unit tests cover RFC0047.4/.5/ .7/.8 at the resolver. Signed-off-by: Jens Holdgaard Pedersen <Jens@holdgaard.org>
…dden columns QueryOptions::visibility carries the caller's two-step decision into the plan: Scoped becomes an IN (ids) over the promoted conversation column OR'd with the self fast path (an ordinary predicate, so it prunes; an empty scope is an empty result); Masked returns every row with the content columns nulled (LogBody::Masked, attribute values unset) and rejects a filter/aggregation on them (QueryError::Forbidden, naming the column, before any IO); TenantWide is today's plan. Engine it tests over real Parquet with promoted columns cover RFC0047.5/.6/.8's engine half. Signed-off-by: Jens Holdgaard Pedersen <Jens@holdgaard.org>
After the tenant gate the querier and MCP query_logs ask the graph
resolver which branch the principal takes inside the tenant and hand
the engine the matching Visibility: tenant-wide (today's plan),
metadata-masked (content columns null, filters/aggregations on them
403 column_forbidden), or scoped (streamed, tenant-filtered, bounded
IN + self fast path; 403 visibility_bound past max_objects, 503
visibility_incomplete on a cut-off stream). Template-level surfaces
(drift, list_templates, template_drift) need tenant-wide content read.
The branch is recorded on ourios.query.visibility{ourios.query.
visibility.branch} (registry + weaver regen) and the request span.
AuthBinding carries the graph principal + groups; auth.openfga.
visibility.* and server_list_objects_deadline_ms parse and map.
RFC0047.4–.8 pass on the served binary against a real OpenFGA container
over Parquet with promoted columns (openfga-resolver CI job runs both
container tests); guides + RFC updated (slice-2 decisions; the
request-carried contextual-tuple arm of RFC0047.5 deferred as a
self-grant, §3.3/§7).

Pull request overview
Implements RFC 0047 slice 2 (layer-2 visibility within a tenant): a two-step OpenFGA decision (tenant-wide vs metadata-masked vs scoped enumeration), query-plan rewrite for scoped principals, and response-time masking + “forbidden column” rejection for metadata-only readers. This extends the slice-1 OpenFGA resolver to enforce conversation-level visibility at plan time (no per-record checks) across both the HTTP query endpoint and MCP tools.
Changes:
- Add layer-2 visibility plumbing end-to-end: OpenFGA two-step + bounded enumeration → querier plan rewrite (
IN (...)/ self fast path) + masking/forbidden-column enforcement. - Add observability for the visibility branch (
ourios.query.visibility{ourios.query.visibility.branch}) and record the branch on request spans. - Add unit + integration coverage, including served-binary E2E tests against a real OpenFGA container, plus docs/RFC updates.

- Around line 132-160: Validate visibility content-column names at configuration
loading so only body, attr.<key>, and resource.<key> are accepted; make the
loader return a configuration error for unknown entries, document that guarantee
near Visibility::mask in crates/ourios-querier/src/visibility.rs:132-160, and
otherwise keep mask unchanged. In crates/ourios-server/src/visibility.rs:64-70,
replace unwrap_or_default() with an explicit no-conversation-object
representation so scoped configurations never pass an empty column to
promoted_expr.
In `@crates/ourios-server/src/visibility.rs`:
- Around line 64-70: Update the GraphVisibility::Scoped handling to keep missing
conversation-object configuration consistent with OpenFgaClient::visibility: do
not construct a scoped visibility with an empty column, and ensure the empty
conversation set bypasses promoted_expr and filtering. Replace the
unwrap_or_default fallback in the column resolution with explicit absent-object
handling.
- Around line 95-142: Add a unit-test module next to reject and
require_tenant_wide. Test every OpenFgaError variant handled by reject,
asserting the response status, stable kind, error_type, and relevant message
context, and test both allowed require_tenant_wide outcomes plus a refused
masked or scoped visibility with its forbidden permission-denied response.
In `@docs/guides/configuration.md`:
- Around line 81-89: Update the configuration example’s documentation to
explicitly state that setting visibility.content_columns replaces the default
content-column set rather than extending it, including the masking implications
for omitted columns.
In `@docs/rfcs/0047-rebac-resolver-and-graph-visibility.md`:
- Around line 358-373: Update the §3.4 configuration example and surrounding
prose to consistently use list_timeout_ms and server_list_objects_deadline_ms,
replacing the obsolete list_timeout and
auth.openfga.server_list_objects_deadline spellings while preserving the

scalar_vec_optintentionally preserves the difference between an absent list and a present-but-empty list, but forauth.openfga.visibility.content_columnsan empty list is invalid (core validation rejects it). Rejecting[]here will produce a clearer schema error and avoids allowing a configuration that can only fail later during core validation.
/// [`scalar_vec`] for an optional list — absent and explicitly empty
/// differ (an empty `content_columns` disables masking; an absent one takes
/// the default set).
fn scalar_vec_opt<'de, D>(deserializer: D) -> Result<Option<Vec<String>>, D::Error>
crates/ourios-server/src/config/file.rs:1531
- This config-parsing test currently treats
content_columns: []as valid, but core OpenFGA config validation rejects an emptycontent_columnslist. Ifscalar_vec_optis updated to reject empty lists (or if runtime validation remains the source of truth), this test input should not use[]as a “valid” example.
"auth:\n tokens:\n - name: a\n token: ${env:CONV}\n tenants: [x]\n openfga:\n api_url: http://fga:8080\n store_id: s\n server_list_objects_deadline_ms: 3000\n visibility:\n objects:\n - type: conversation\n column: ${env:CONV}\n self_principal_column: attr.user.hash\n content_columns: []\n max_objects: 100\n list_timeout_ms: 500\n",
crates/ourios-server/src/config/file.rs:1558
- After switching the test input away from
content_columns: [], the assertion should also validate the non-empty list. Keeping the “explicit empty” assertion here would no longer match the intended (and core-validated) contract thatcontent_columnsmust be non-empty when present.
assert_eq!(
visibility.content_columns.as_deref(),
Some(&[][..]),
"explicit empty"
);
crates/ourios-server/src/config/file.rs:1580
- Once empty lists are rejected for
auth.openfga.visibility.content_columns, this test should also assert thatcontent_columns: []fails schema validation (similar to the existing typo/unknown-key checks). That keeps the “masking can’t be disabled” contract pinned at the config boundary instead of only in core validation.
let err = parse(
"auth:\n openfga:\n visibility:\n objects:\n - kind: conversation\n",
&lookup,
)
.expect_err("typo");
crates/ourios-server/src/config/file.rs:496
- The doc comment implies an explicit empty
content_columnslist “disables masking”, but core OpenFGA validation rejects an empty list (auth.openfga.visibility.content_columns must not be empty). This is misleading for operators reading the config schema in this file.
This issue also appears in the following locations of the same file:
- line 870
- line 1531
- line 1554
- line 1576
/// The content columns a metadata-only reader may not read. `None` =
/// the `GenAI` default set; an explicit empty list disables masking.
crates/ourios-server/src/visibility.rs:55
ourios.query.visibilityis specified so that thescopedbranch counts every streamed conversation enumeration issued, butmetrics.record_visibility()is only called afterresolver.visibility(...)returnsOk. When the scoped enumeration fails closed (BoundExceeded/Incomplete), the enumeration still happened but the metric/span never recordscoped, which undercounts and makes the “no enumeration” assertion harder to validate from telemetry.
let decision = resolver

… failed scoped enumerations Copilot's follow-ups on #706: the config schema no longer says an empty content_columns disables masking (it is rejected at startup; the parse test uses a real list), and the scoped branch is recorded on ourios.query.visibility / the span even when the enumeration fails closed (BoundExceeded / Incomplete) — 'scoped' means a stream was issued.

OpenFgaError::InvalidTenantis raised when the tenant string cannot form an authorization-graph object id, but the rejection message currently claims the tenant is outside the token’s allowed set (which is a different failure and is already handled by the tenant gate). This makes 403s for invalid tenant IDs misleading to operators.

Visibility::validatecurrently treatsprojectas a forbidden “read” of masked columns. That is stricter than the documented contract (reject filters/aggregations on masked columns, but allow returning them as null/masked), and it blocks queries that merely projectbody/content fields without using them for filtering/aggregation.
Stage::Project(projected) => fields.extend(projected.iter()),
… projection is not a read Copilot follow-ups: an InvalidTenant refusal is 403 tenant_unaddressable naming the object-id rule (not the tenant-set message, which is a different failure); Visibility::validate no longer treats a projected content column as a forbidden read — projections come back masked.

ourios.query.visibilityis documented as “scopedcounts every streamed conversation enumeration issued” (semconv/registry/metrics.yaml:419–423), but this error-path only records thescopedbranch forBoundExceeded/Incomplete. A streamed enumeration that fails withOpenFgaError::Unavailable(e.g. HTTP non-2xx, timeout, NDJSON decode, or server error frame fromOpenFgaClient::streamed_list_objects) will not be counted asscoped, even though a stream was issued.
Err(e) => {
// A scoped enumeration that failed closed still happened —
// count it, so `scoped` on `ourios.query.visibility` is exactly
// "a stream was issued".

TenantObjects::newvalidates the raw tenant id withis_object_id, but then percent-encodes%//for the conversation/tool prefixes. That encoding can expand the tenant segment and make the resulting object-id half (<enc(T)>/…) exceed OpenFGA’s 256-byte limit even when the raw tenant passed validation, which will make all tenant-scoped objects for that tenant unnameable at runtime.
let encoded = encode_tenant_segment(tenant);

Summary
RFC 0047 implementation slice 2 of 4 — layer-2 visibility inside a tenant (RFC0047.4–.8): the planner two-step, masking, and the bounded scoped enumeration. Follows #705 (layer-1 resolver).
auth.openfga.visibility.*(objects[type,column]—conversationonly in v1;self_principal_column;content_columnswith the GenAI default set;max_objects;list_timeout_msstrictly belowserver_list_objects_deadline_ms) andOpenFgaResolver::visibility:Check(can_read_content)→ tenant-wide;Check(can_read_metadata)→ metadata-only; else the streamedListObjects(can_read_content, conversation)filtered to theconversation:T/prefix, counting only tenant ids toward the bound —BoundExceeded/Incompletefail closed and are never cached; the two checks cache with the session TTL. Principal ids are validated as object ids (Copilot's carry-over from feat(auth): rfc 0047 slice 1 — openfga resolver (RFC0047.1–.3) #705).QueryOptions::visibility→Plan:Scopedisattr.gen_ai.conversation.id IN (…)OR the self fast path (an ordinary promoted-column predicate, so it prunes; empty scope = empty result);Maskednulls the content columns on returned rows (LogBody::Masked, attribute values unset) and rejects a filter/aggregation on them (QueryError::Forbidden, naming the column, before any IO);TenantWideis today's plan./v1/queryand MCPquery_logs;403 visibility_bound("ask for tenant-wide read"),503 visibility_incomplete,403 column_forbidden; template-level surfaces (drift,list_templates,template_drift) require tenant-wide content read (403 visibility_scoped) — templates are mined from bodies. Branch recorded onourios.query.visibility{ourios.query.visibility.branch}(registry + weaver regen) and the request span.AuthBindingnow carries the graph principal + groups.openfga/openfgacontainer (pre-written Parquet, OIDC fixture issuer, agent claim, delegation revoked past the TTL, bound-per-tenant, masking) — theopenfga-resolverCI job now runs both container tests. Green locally.Decision to flag (RFC-level, deferred not built)
RFC §3.3 bridge (b) / one arm of RFC0047.5 lets the request carry
{conversation:T/<id>#participant@<principal>}as a contextual tuple. That tuple is asserted by the very principal it grants — any scoped caller could name any conversation id and read it, a self-granted escalation the graph never checked (contextual tuples are an application-trusted input; the IdP-minted group claim is one, a caller-supplied tuple is not). This PR implements the data-verified self fast path (a) only, marks that RFC0047.5 arm deferred with the question in §7, and leaves the RFC atred. If you want the bridge anyway (e.g. behind a trusted-carrier rule), say so and I'll add it as a follow-up.Invariants / hazards touched
body: {"kind":"masked"},"value": null), never an indistinguishable absence.auth.openfga; with it, one or two ~1 msChecks per query (session-cached) and a streamed enumeration only for scoped principals.Remaining slices: MCP tool gate (RFC0047.9), emitter + erasure (.10–.11), then the green flip.
