docs(rfc): rfc 0048 — graph operational surfaces (specified) - #711
Conversation
The operational surfaces the RFC 0047 implementation had to choose on its own, promoted to contract with criteria: one tenant id grammar at every boundary (removing the graph's percent-encoding), the graph's identity keys as configuration with the semconv keys as defaults, an operator front door for erasure over the RFC 0047 store marker (CLI verbs), a backfill pass for pre-existing data, formal rejection of the request-carried contextual-tuple bridge, and a loud startup event for the list-timeout / server-deadline coupling. RFC 0047 §7 item closed by reference. Signed-off-by: Jens Holdgaard Pedersen <Jens@holdgaard.org>

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The RFC defines graph identity, erasure, and backfill behavior, but the current text still contains conflicting conversation-ID rules, incomplete request-field semantics, configuration-name mismatches, and backfill/erasure coordination gaps that could lead to rejected valid identifiers, recreated deleted data, or blocked erasure processing. Merge should wait for these contract details to be corrected or explicitly accepted. Possibly related PRs

Pull request overview
Adds RFC 0048 (specified) to formalize operational contracts that RFC 0047’s implementation slices had to decide ad hoc—standardizing tenant ID grammar across boundaries, making identity keys configurable, and defining explicit CLI surfaces for erasure and backfill (while rejecting request-carried contextual tuples).
Changes:
- Adds RFC 0048 spec covering tenant-id grammar, identity-key configuration, erasure/backfill CLI surfaces, and deadline coupling observability.
- Links RFC 0048 into the mdBook SUMMARY.
- Updates RFC 0047 open questions to record that the request-carried contextual tuple bridge is rejected by RFC 0048.

- Around line 139-142: Add a console or text language identifier to the opening
fences for both command-example blocks in the graph operational surfaces
documentation, including the blocks containing the graph erase/erasures commands
and the later command example.
- Around line 163-169: Update the backfill flow described in the graph
operational surfaces RFC to coordinate with erasure using a store-backed
exclusion, lock, or generation fence, preventing tuples for an erased
conversation from being recreated when backfill writes after erasure. Add an
acceptance scenario covering concurrent backfill and erasure, and preserve
resumable idempotent batching for unaffected data.
- Around line 160-164: Update the graph backfill documentation around the
`--from` option to define its boundary semantics: specify whether the date is
inclusive or exclusive, identify the partition timestamp used for filtering, and
state the timezone used to map timestamps to dates. Express the resulting
interval explicitly, including whether it is half-open, so backfill behavior is
reproducible.
- Around line 99-105: Define the conversation-ID grammar explicitly in the RFC,
choosing whether it reuses the object-ID grammar or a separate CLI grammar, and
apply that choice consistently across the emitter, planner, erasure path, and
CLI. Correct the documented byte budget to 127 bytes for the ID with a 128-byte
tenant, or 114 bytes only when the 256-byte cap includes the conversation:
prefix.
- Around line 173-179: Remove arbitrary contextual-tuple inputs from
ListObjectsRequest::contextual_tuples and OpenFgaClient::check, and stop
forwarding caller-supplied tuples to OpenFGA. Build tuples only from verified
OIDC groups using TupleKey with the principal as user, “member” as relation, and
“team:<group>” as object after validating each group as an OpenFGA object ID.

- RFC0048.4 acceptance criteria says “Given an id outside the grammar…”, but the grammar defined in §3.1 is for tenant ids specifically. To keep the criterion precise/testable, it should name the tenant id (or define a conversation-id grammar separately).

- This sentence says contextual tuples reach the graph from “exactly two carriers”, but only lists the OIDC group claim and then says “nothing else in v1”. That’s a contradiction; either list both carriers or change this to “exactly one carrier”.

- §3.3 says both CLI verbs refuse a “tenant or conversation id outside the §3.1 grammar”, but §3.1 only defines the tenant-id grammar. As written, this is internally inconsistent and could be read as applying tenant constraints to conversation ids without ever specifying a conversation-id grammar.

- The acceptance criteria define RFC0048.1 through RFC0048.8 (8 criteria), but the PR description states there are seven (RFC0048.1–.7). To avoid confusion when tracking scenarios, align the stated criteria count (and update the PR description accordingly).

- Backfill lock marker naming is inconsistent with the existing convention that object-store tenant path segments are percent-encoded (RFC 0005 §3.4) and with RFC 0047’s erasure marker (
erasure/tenant_id=<enc>/…). Since the tenant grammar still allows bytes like%, the lock marker should also use the same<enc>encoding to avoid ambiguous/unportable object keys.

- The PR description states there are seven acceptance criteria (RFC0048.1–.7), but this RFC includes RFC0048.8 as well. To avoid confusion for readers and test planning, the acceptance-criteria intro should explicitly reflect the full criterion range used in the document (or the criteria should be renumbered/merged to match the stated count).

Summary
RFC 0048 — Graph operational surfaces (spec-only,
specified). The follow-up to RFC 0047's implementation retrospective (#705–#710): the four surfaces the slices had to decide on their own, promoted to contract with acceptance criteria — or replaced where the slice's choice was a workaround.:#/whitespace) — selector, querier/MCP, token config, OIDC claim, graph object. Removes RFC 0047's percent-encoding of the tenant segment (a smell that said the grammar belonged upstream). Amends RFC 0046 §3.1; pre-production!.visibility.identities.user_columns/agent_columns, defaults = today's semconv keys) next to the already-explicit conversation column.ourios-server graph erase/graph erasuresover the RFC 0047 store marker (the only channel), no HTTP/MCP surface; completion observable via marker, audit kind 9, metric, and one structured event.ourios-server graph backfill --tenant Tfeeds the graph from data stored before the graph was configured (idempotent, never rewrites Parquet).list_timeout_ms/ server-deadline assumption loud at startup.Eight criteria (RFC0048.1–.8); the RFC 0047 container harness carries the integration arms.
