Implements RFC 0046 — out-of-band tenancy (#699, specified): the credential/request names the tenant, the OTLP payload never does. All eleven §5 criteria have tests; the green flip follows in its own doc PR (RFC 0043/0044/0045 precedent), and RFC 0045 becomes superseded there.

Slices (one commit each)

  1. ourios-walFrameKind::TenantOtlpBatch = 0x03 + TenantBatch::{encode,decode} (u16 LE len ‖ tenant ‖ protobuf; prefix validated before the protobuf is exposed — RFC0046.11). RFC 0008's frame table gains the amendment; the RFC0008.5 unknown-kind fixture moves 0x030x04 (fixture value only, contract unchanged).
  2. ourios-ingesterreceiver/selector.rs: X-Ourios-Tenant (HTTP) / x-ourios-tenant (gRPC), required exactly once, normalised (trim, ≤256 B, no control chars), 400/INVALID_ARGUMENT before authorization and any WAL work (RFC0046.1/.7). ingest_bound takes the selected TenantId; the RFC 0026 binding check is set-membership on it (RFC0046.2); every record is materialised under it (tenant::assign, RFC0046.3); the frame is 0x03. Recovery replays 0x03 by its own prefix; a legacy 0x01 frame is SinkRejected naming the offset and remedy — never corruption (RFC0046.5). TenantRule/fan_out, the rule-epoch log and the divergence detector are removed (RFC0046.9).
  3. ourios-server + surfacereceiver.tenant.* config, tenant_derivation, the Helm passthrough removed; the semconv registry entries for the RFC 0045 detector are deprecated (obsoleted by RFC 0046), not deleted; docs (quickstart, README, agent-telemetry, configuration guide, RFC 0003 §6.3 superseded note), dogfood Collector/env, kind smoke test and collector interop all set the header.

Tests (RFC0046.n)

  • .1/.2/.3/.7/.10 served-binary over both transports (open mode → static token): missing selector 400/INVALID_ARGUMENT naming the header; hygiene (trim, empty, oversize, repeated header/metadata); one export with three groups (fluxcd, checkout, no service.name) all in the selected tenant, service == "fluxcd" a plain filter; out-of-set 403; reserved-char selector round-trips; no tenant is ever derived.
  • .4 two tenants, no service.name, acked then lost before flush → replay lands each in its acknowledged tenant from the 0x03 frame alone.
  • .5/.11 recovery-driver unit tests (legacy frame, malformed prefixes); .6 ourios-wal adds the 0x03 dimension (round trip, torn-tail heal, bit-flip corruption) without editing the RFC 0008 criteria; .8 collector interop exporter headers:; .9 git grep in this description (nothing left).
  • Retired, each replaced (CLAUDE.md §6.2 contract change made explicit): RFC0003.3 fan-out → RFC0046.3; RFC0003.4 → RFC0046.1; RFC0003.11 tenancy arm → missing selector; RFC0026.3 → selector binding; invariant_3_7_3_tenant_per_resource_logs, rfc0045_* suites removed. Harness helpers gain the selector, replay_batches, tenant_for.

Invariants touched

  • §3.7 multi-tenancy — the reason for the RFC: no producer chooses its own tenant any more; one export = one tenant; the tenant is opaque and coarse.
  • §3.4 WAL-before-ack — unchanged: the 0x03 frame is fsynced before ack; the tenant rides in the frame so replay needs no derivation (RFC0046.4).
  • RFC 0008 frame format — a new kind inside the reserved range, per §6.2's "future kinds without a version bump"; invariants payload-agnostic (RFC0046.6). Legacy 0x01 frames refused at replay per the persisted-layout ruling.

Verification

cargo fmt --all --check · cargo clippy --workspace --all-targets --all-features -D warnings · cargo nextest run --workspace --all-features (1311 passed) · weaver registry check + regenerate (no diff) · helm lint + render-tests.sh · mdbook build.

Tracks #700; supersedes the RFC 0045 mechanism (#692).

📝 Walkthrough

Walkthrough

Out-of-band tenancy replaces service.name-derived tenant resolution. HTTP and gRPC exports now require validated tenant selectors. Ingestion assigns the selected tenant directly and persists tenant-bearing WAL frames. Recovery, configuration, tests, and documentation use the new model.

Changes

Out-of-band tenancy

Layer / File(s) Summary
Selector validation and ingestion APIs
crates/ourios-ingester/src/receiver/*
HTTP headers and gRPC metadata now provide the tenant. Selectors are validated, authorization checks use the selected tenant, and records are assigned directly.
Tenant-bearing WAL frames and recovery
crates/ourios-wal/src/*, crates/ourios-ingester/src/recovery.rs
TenantOtlpBatch frames and the TenantBatch codec preserve tenant identity through WAL replay. Legacy untagged OTLP frames are rejected during recovery.
Ingester and server integration
crates/ourios-ingester/tests/*, crates/ourios-server/src/*, crates/ourios-server/tests/*
Pipeline, recovery, transport, authentication, persistence, and end-to-end tests now use explicit tenant selectors and tenant-bearing frames.
Operational configuration and documentation
.github/workflows/*, README.md, docs/*, deploy/helm/*, dev/observability/*, justfile, semconv/*
Configuration examples and telemetry exporters now send tenant headers. Removed tenant derivation settings and deprecated divergence telemetry metadata.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to cd612

The PR moves tenant selection into the request and persists it in a dedicated WAL envelope, but a durability test still treats that envelope as raw OTLP and recovery errors identify the frame kind incorrectly; this can undermine regression coverage and mislead operators during WAL recovery, so those issues should be fixed or explicitly accepted before merge.

Pull request overview

Implements RFC 0046 out-of-band tenancy across the ingest surface: the tenant is selected via request credential/header/metadata (never derived from OTLP payload), and the WAL persistently records that tenant in a new frame kind so replay needs no derivation.

Changes:

  • Add WAL frame kind 0x03 TenantOtlpBatch with a TenantBatch payload codec, and update RFC 0008 documentation/tests accordingly.
  • Require X-Ourios-Tenant (HTTP) / x-ourios-tenant (gRPC) on every export; plumb selected TenantId through ingest, auth binding, WAL append, and recovery.
  • Remove RFC 0045 tenant-derivation config/watch/detector paths; deprecate the corresponding semconv registry entries; update docs, Helm, and interop harnesses.

Extend the round-trip test to the new kind.

read_frame now accepts 0x03, but frame_round_trips_through_write_then_read (Line 241) still iterates only OtlpBatch and AuditEvent. Add TenantOtlpBatch to that array. This pins the write→read symmetry and the 0x03 discriminant at the frame layer, not only through the Wal integration test.

Correct the segment-rotation comment.

The comment states that a tiny segment size closes the first segment. The config uses MIN_SEGMENT_SIZE_BYTES, and rotation happens because each frame is about half a segment. Restate the actual mechanism.

Two control replays restate the tenant instead of reading it from the frame. crates/ourios-ingester/tests/it/ingest_support/mod.rs now exposes replay_batches, which asserts FrameKind::TenantOtlpBatch and returns the tenant decoded from each frame. Both sites still call replay_frames and then hardcode the tenant, so neither control replay verifies the persisted tenant.

123-139: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Consider an in-place encoder to avoid one full payload copy per batch.

encode allocates a new Vec and copies all of protobuf. The ingest path in crates/ourios-ingester/src/receiver/pipeline.rs already materialises the protobuf with request.encode_to_vec(), so every batch is copied twice on the WAL hot path. Payloads reach frame-size scale, so the copy is proportional to batch size.

An encode_into(tenant, &mut Vec<u8>) (or a prefix writer the caller uses before prost::Message::encode) removes the second copy and keeps the current encode as a thin wrapper for tests.

52-54 and crates/ourios-ingester/tests/it/rfc0003_2_crash_before_ack.rs line 62.

In `@crates/ourios-server/tests/it/rfc0029_oidc.rs`:
- Around line 279-281: Update the documentation above batch to state that
tenant_request selects the tenant from the x-ourios-tenant header, while
batch(tenant) only sets the service.name resource attribute; remove wording that
implies tenant identity is derived from service.name.

In `@docs/guides/agent-telemetry.md`:
- Around line 83-87: Update the later tenant descriptions in the telemetry guide
to identify the x-ourios-tenant exporter-header value as the tenant, while
describing service.name only as producer metadata; keep the existing directory
and filtering guidance consistent with this distinction.

In `@docs/rfcs/0003-otlp-receiver.md`:
- Around line 643-649: Revise the RFC 0046 supersession notice to distinguish
its failure semantics from RFC0003.4: state that the tenant selector is
validated before payload decoding, missing selectors are rejected, and
out-of-set selectors undergo the specified authorization checks. Remove the
claim that these cases are the rejection defined by RFC0003.4 while retaining
the historical-design context.

In `@docs/rfcs/0008-wal.md`:
- Line 677: Update §6.2.3 “Payload encoding” to add a FrameKind::TenantOtlpBatch
entry documenting the little-endian u16 length prefix, tenant bytes, protobuf
payload, and TenantBatch bounds. Mark the existing OtlpBatch encoding entry as
superseded by the RFC 0046 amendment, removing claims about replay tenant
derivation and fan-out.

Nitpick comments:
In `@crates/ourios-ingester/tests/it/rfc0008_8_ingest_order.rs`:
- Around line 79-84: Update the control replay in
crates/ourios-ingester/tests/it/rfc0008_8_ingest_order.rs lines 79-84 to use
replay_batches instead of replay_frames and pass through each frame’s decoded
tenant, removing the hardcoded TenantId::new("checkout"). Apply the same change
in crates/ourios-ingester/tests/it/rfc0035_2_encode_barrier.rs lines 167-172,
removing TenantId::new("svc"), so both replays validate persisted tenants.

In `@crates/ourios-ingester/tests/it/rfc0046_4_wal_frame_carries_tenant.rs`:
- Around line 28-34: Replace the local never_flush helper in the test with the
shared ingest_support::never_flush implementation, importing it alongside the
other test helpers. Remove the now-unused FlushConfig and Duration imports, and
keep existing call sites unchanged.

In `@crates/ourios-wal/src/frame.rs`:
- Around line 185-190: Extend the cases used by
frame_round_trips_through_write_then_read to include FrameKind::TenantOtlpBatch
alongside the existing kinds, preserving the test’s write→read round-trip
assertions and covering the 0x03 discriminant.

In `@crates/ourios-wal/src/lib.rs`:
- Around line 123-139: Refactor the WAL encoding flow around
TenantBatchError::encode to add an in-place encode_into API that appends the
tenant length prefix and tenant bytes to a caller-provided Vec, allowing the
caller to encode the protobuf directly afterward without copying it. Update the
ingest pipeline’s request.encode_to_vec() path to use this API, while retaining
encode as a thin compatibility wrapper for tests and preserving existing tenant
validation and output format.

In `@crates/ourios-wal/tests/it/rfc0046_6_frame_kind_dimension.rs`:
- Around line 147-157: Update the comment above the WAL append sequence to state
that rotation occurs when two frames, each approximately half the minimum
segment size, fill the segment; do not describe the segment size itself as tiny
or claim the first append closes it.

…(RFC 0046 §3.3)

FrameKind::TenantOtlpBatch = 0x03 with TenantBatch::{encode,decode}
(u16 LE len ‖ tenant ‖ protobuf; prefix validated before the protobuf
is exposed — RFC0046.11). RFC 0008's frame table gains the amendment;
the RFC0008.5 unknown-kind fixture moves from 0x03 to 0x04 (fixture
value only, the contract is unchanged).

Signed-off-by: Jens Holdgaard Pedersen <Jens@holdgaard.org>
…; derivation removed (RFC 0046)

- receiver/selector.rs: X-Ourios-Tenant (HTTP) / x-ourios-tenant (gRPC),
  required exactly once, normalised (trim, ≤256 B, no control chars);
  400 / INVALID_ARGUMENT before authorization and any WAL work
- IngestPipeline::ingest_bound takes the selected TenantId; the RFC 0026
  binding check is a set-membership on it; every record is materialised
  under it (tenant::assign); the frame is TenantOtlpBatch (0x03)
- recovery replays 0x03 by its own tenant prefix; a legacy 0x01 frame is
  SinkRejected naming the offset and remedy (not corruption)
- TenantRule/fan_out, the rule-epoch log and the divergence detector are
  removed (RFC 0046 §3.4)
- tests: RFC0003.3/.4 and the RFC 0045 suites retired (replaced by the
  RFC0046 criteria); RFC0003.11 tenancy arm → missing selector; RFC0026.3
  → selector binding; harness helpers gain the selector, replay_batches,
  tenant_for

BREAKING CHANGE: every OTLP export must carry the tenant selector
(X-Ourios-Tenant / x-ourios-tenant); resource attributes never choose the
tenant; WAL frames written before this version (kind 0x01) are refused at
replay — drain or delete the WAL when upgrading (RFC 0046 §3.3).

Signed-off-by: Jens Holdgaard Pedersen <Jens@holdgaard.org>
… Helm, dogfood, RFC0046 tests

- receiver.tenant config section, tenant_derivation and the Helm
  passthrough are removed; the server hands the transport-selected tenant
  to the pipeline and replays 0x03 frames without derivation
- semconv: the RFC 0045 detector metric/events/attributes are deprecated
  (obsoleted by RFC 0046), never deleted; constants regenerate unchanged
- served-binary test for RFC0046.1/.2/.3/.7/.10 (both transports, open
  mode + static token, hygiene incl. reserved-char round trip); RFC0046.4
  on the WAL crash shape; RFC0046.6 adds the 0x03 dimension to the RFC
  0008 invariants; RFC0046.8 via the collector interop exporter header;
  RFC 0003 §6.3 marked superseded, RFC0003.16 / RFC0008.10 / soak / OIDC
  / TLS harnesses carry the selector
- docs: quickstart, README, agent-telemetry, configuration guide; dogfood
  Collector + env set x-ourios-tenant; Helm values note the LOGS header

BREAKING CHANGE: receiver.tenant.* configuration and the Helm
receiver.tenant value no longer exist; every OTLP export must name its
tenant out of band (RFC 0046).

Signed-off-by: Jens Holdgaard Pedersen <Jens@holdgaard.org>
…es the kind, stale docs

- rfc0019 S3 tests name each export's tenant (the isolation arm is now two
  exports, one per tenant — RFC 0046 §3.2)
- recovery::reject names the actual frame kind in SinkRejected details
- RFC 0008 §6.2.3 documents the TenantOtlpBatch payload and the 0x01
  replay refusal; RFC 0003 §6.3 note carries RFC 0046's failure semantics;
  agent-telemetry / justfile / oidc harness docs no longer say tenant ==
  service.name; stale OtlpBatch comments in ingester tests

  • The comment and assertion message still refer to OtlpBatch, but this test now asserts FrameKind::TenantOtlpBatch. Updating these strings will avoid misleading failures/diagnostics when the assertion trips.
