Previously the conversation was resolved *after* the +envelope was rendered and dispatched, so the agent received an envelope with no +`conversation` key despite the message being persisted with a conversation_id. + +The fix hoists sender resolution and Phase 5 conversation resolution above the +delivery-envelope render. A single `effectiveConv` value, computed once, is used +for both the envelope and the persisted `storeMsg.ConversationID`. + +## Tracked Drift + +### 1. Write-deny 409 now fires before dispatch (behaviour change) + +Previously, a conversation-resolution failure under write-deny returned 409 +*after* `dispatchWithBrokerRetry` had already delivered the message — the agent +had the message and the caller had a failure, making client retries unsafe +(double-delivery). + +After the hoist, a 409 means nothing was delivered and a retry is safe. This is +fail-closed, consistent with the standing rule that messaging switches fall back +to refusal (*under-granting is recoverable, over-granting is not*). + +**Impact:** Messages that today are delivered-then-409'd will instead be refused +outright. The direction is strictly safer. + +### 2. Dispatch failure can leave a conversation row with no messages + +Resolution writes a conversation row. Hoisting it above dispatch means a +conversation row may be created for a message that is subsequently never +delivered (dispatch timeout, 502, etc.) and never persisted. + +This is accepted because DM and thread conversations are **resolved by +deterministic key** — the next message from the same user to the same agent +resolves the identical conversation and uses it. An empty conversation is inert +and self-healing, not an orphan requiring cleanup. + +### 3. Broadcasts with surface + external_ref no longer carry a conversation in the envelope + +Base rendered the Phase 11 conversation into the broadcast envelope while +persisting no conversation_id on the row — exactly the envelope/row disagreement +this defect exists to remove. The fix unifies on no-conversation-for-broadcasts, +matching the documented invariant at `handlers_agent_messaging.go:1898` +("broadcasts deliberately skip conversation resolution"). Phase 11 still creates +the conversation row; it is simply not stamped on the broadcast. + +### 4. Tripwire: Phase 11 unification changes which conversation messages persist into + +When both Phase 11 (explicit `surface` + `external_ref`) and Phase 5 (inferred +DM/thread) produce a result, the precedence rule selects Phase 11. Phase 11 +produces a **group** conversation keyed on the external ref; Phase 5 produces a +**direct** conversation keyed on the sender/agent pair. + +No live caller sets `surface` + `external_ref` on this endpoint today, so +nothing changes in practice. **The day anyone enables Phase 11 on a plugin that +also resolves DM conversations, Discord messages will move from DM conversations +into group conversations.** This is Alternative B from the design, which was +explicitly rejected because it splits every user's history at the deploy +boundary. It must not happen as a side effect of enabling Phase 11; it requires a +deliberate product decision and migration plan. diff --git a/cmd/boot_backfill_test.go b/cmd/boot_backfill_test.go new file mode 100644 index 0000000000..ba8f335aa3 --- /dev/null +++ b/cmd/boot_backfill_test.go @@ -0,0 +1,910 @@ +// Copyright 2026 Google LLC +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +//go:build !no_sqlite + +package cmd + +import ( + "bytes" + "context" + "encoding/json" + "errors" + "log/slog" + "testing" + "time" + + "github.com/GoogleCloudPlatform/scion/pkg/store" + "github.com/google/uuid" + "github.com/stretchr/testify/assert" + "github.com/stretchr/testify/require" +) + +// --------------------------------------------------------------------------- +// Store wrappers for fault injection +// --------------------------------------------------------------------------- + +// listProjectsFailStore wraps a real store.Store and overrides ListProjects +// to return an error, simulating a run-level failure in the project +// enumeration step.
