From 0ff7b8614037f0dbb4083f72468f033fd83de6c7 Mon Sep 17 00:00:00 2001 From: "Scion Agent (ca-msg-g1)" Date: Sun, 30 Aug 2026 20:01:28 +0000 Subject: [PATCH 001/105] feat(messaging): add `scion server attribution-report` command (G1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Read-only command that scans all messages and reports conversation attribution completeness with three distinct unattributed buckets: - backfillable: both principals are valid UUIDs, key derivation succeeds - non-UUID principal: at least one principal fails uuid.Parse (federated identities, slugs); permanently unattributable without DEF-32 - unresolvable: both principals are UUIDs but derivation still fails Non-zero non-UUID principal or unresolvable counts are declared flip-blocking in the command output itself. Non-UUID examples enumerate the offending principal IDs for diagnosis. Uses production DeriveConversationKey — no reimplementation. Does not import or reference DivergenceMetrics. Tests: - Mutation guard: seeds messages, runs report, asserts no row changed - DivergenceMetrics dependency guard: parses source, asserts no reference - Production derivation guard: asserts source calls messaging.DeriveConversationKey - Bucket classification, flip-blocking output, unresolvable examples, multi-project aggregation, empty database AC-G-1, AC-G-2, AC-G-3, AC-G-10. --- cmd/server_attribution_report.go | 375 ++++++++++++++++++++++ cmd/server_attribution_report_test.go | 439 ++++++++++++++++++++++++++ 2 files changed, 814 insertions(+) create mode 100644 cmd/server_attribution_report.go create mode 100644 cmd/server_attribution_report_test.go diff --git a/cmd/server_attribution_report.go b/cmd/server_attribution_report.go new file mode 100644 index 0000000000..5ba8a55657 --- /dev/null +++ b/cmd/server_attribution_report.go @@ -0,0 +1,375 @@ +// 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. + +package cmd + +import ( + "context" + "fmt" + "io" + + "github.com/GoogleCloudPlatform/scion/pkg/messaging" + "github.com/GoogleCloudPlatform/scion/pkg/store" + "github.com/google/uuid" + "github.com/spf13/cobra" +) + +var ( + attrReportProject string + attrReportDB string +) + +var serverAttributionReportCmd = &cobra.Command{ + Use: "attribution-report", + Short: "Report on conversation attribution completeness", + Long: `Scan messages and report how many are attributed to a conversation, +how many can be backfilled, how many have non-UUID principals (and therefore +cannot be attributed), and how many are otherwise unresolvable. + +This is a READ-ONLY command: it examines the database and reports findings +without modifying any rows. + +A non-zero 'non-UUID principal' or 'unresolvable' count means the conversation +read switch CANNOT be safely enabled — those messages would become invisible. + +Examples: + # Report for all projects: + scion server attribution-report + + # Report for a specific project: + scion server attribution-report --project `, + RunE: runServerAttributionReport, +} + +func init() { + serverCmd.AddCommand(serverAttributionReportCmd) + serverAttributionReportCmd.Flags().StringVar(&attrReportProject, "project", "", "Report for a specific project ID (default: all)") + serverAttributionReportCmd.Flags().StringVar(&attrReportDB, "db", "", "Database DSN (overrides config/env)") +} + +// AttributionReport holds the results of the attribution completeness scan. +type AttributionReport struct { + // Total is the count of all messages examined. + Total int + // Attributed is the count of messages with a non-empty conversation_id. + Attributed int + // Backfillable is the count of unattributed messages whose sender and + // recipient IDs are both valid UUIDs — these can be attributed by the + // backfill command. + Backfillable int + // NonUUIDPrincipal is the count of unattributed messages where at least + // one principal ID is not a valid UUID (e.g. federated identities, + // slugs).

Content-Transfer-Encoding: 8bit G1-a: Add broadcast bucket. Broadcasts with NULL conversation_id are now a separate flip-blocking bucket ('unattributed — broadcast'). The backfill service skips broadcasts (backfill.go:127), so they are never attributed. All three read-switch sites (handlers_messages.go:70, :259, handlers_chat_v2.go:1782) scope by ConversationID with no broadcast- specific alternative path — broadcasts become invisible at the flip. G1-b: Reconciliation check. On all-projects runs, compare the report's unattributed total against CountUnbackfilledMessages(ctx, ""). Print a loud RECONCILIATION MISMATCH line if they disagree, and treat the mismatch as flip-blocking. G1-c: Behavioral production derivation test. Table of KeyInputs with known-pass and known-fail cases run through the classifier; asserts exact bucket placement.

Unresolved conversations now return HTTP 409 with machine-readable code "conversation_not_resolved" instead of silently falling back to the legacy filter. Fix the DM key parse bug: a key with a part count other than 5 now returns 409 with code "invalid_dm_key" (defense-in-depth; validDMKey's regex already rejects non-5-part keys at the HTTP layer with 400). Sites modified: - S1: handleConversationHistory (handlers_chat_v2.go) - S2: handleMessages (handlers_messages.go) - S3: handleAgentMessages (handlers_messages.go) Switch-OFF behaviour is unchanged.

Remove the postgres-only guard — initOperationalSettings now runs on all drivers. 2. On init failure, log at ERROR with the wrapped error and continue booting (fail-soft) rather than aborting the hub. The messaging switches remain fail-closed (OFF) when OperationalSettings is nil. 3. Update doc comments on OperationalSettings and startSettingsPropagation to reflect driver-agnostic usage. 4.

Unlike the SQLite store, generation is unconditional — Postgres Init() migrations guarantee the conversations table exists, so there is no hasConversationsTable() gate. The legacy path is removed (dead code); the SQLite store retains it because hasConversationsTable() can return false in pre-migration environments. Behavior changes on Postgres (both tightenings): - Empty ConversationID + empty ProjectID: previously succeeded silently via the legacy path (inserting a topic with no project_id). Now fails with "project_id is required" because the auto-generated ConversationID triggers the existing ProjectID guard. The handler always provides ProjectID. - Partially-migrated DB without conversations table: previously succeeded via the legacy path (topic with no conversation). Now fails because the generated ConversationID triggers the dual-write tx, and the INSERT INTO conversations fails. Silent success becomes loud failure. This is intentional — a topic without a conversation is the defect being fixed. NOTE: the Postgres path is unverified by test. No pg test infrastructure exists in this repo (no testcontainers, dockertest, sqlmock, or postgres build tag; zero test files reference pgWebChatStore). The SQLite store's identical logic IS tested.

Both handler call sites updated: - handlers_chat_v2.go S1: passes wcs (already holding the topic) - handlers_messages.go S3: passes s.webChatStore (had no topic lookup) Resolution order: topic lookup first; if store.ErrNotFound (not a native topic), fall through to external_ref. Infrastructure errors do NOT fall through. Non-native surfaces with well-formed external_ref are preserved.

This makes a corrupted hub_settings row invisible to operators. Add a Malformed bool to sectionState, set it at parse time in Refresh and Update via json.Valid, and log the failure at error level ONCE per ingest. Getters can now distinguish "validated document" from "unreadable document" — which is the prerequisite for making default-ON and fail-closed simultaneously expressible (Phase 9a §4.6.2). This commit changes no default values and no getter behaviour. The Malformed field is generic to all sections, not just messaging, so every section benefits from the parse-time detection. --- pkg/hub/operational_settings.go | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) diff --git a/pkg/hub/operational_settings.go b/pkg/hub/operational_settings.go index eeb48a25d8..0f07e1d4ab 100644 --- a/pkg/hub/operational_settings.go +++ b/pkg/hub/operational_settings.go @@ -42,6 +42,13 @@ type sectionState struct { UpdatedAt time.Time UpdatedBy string Origin string + + // Malformed is true when Value is not valid JSON.

Stale keys are rejected on write (additionalProperties: false) and self-clean on first PUT. operational_settings.go: new ConversationEnvelopeSwitch() getter using the three-way sectionState split (absent → ON, malformed → OFF, omitted → ON). Old getters removed. admin_messaging.go: collapse from two fields to one. Explicit-null reset uses DeleteSection so the absent→default (ON) path runs, rather than writing a literal false (the f:=false trap in §4.6.3). server.go, handlers_messages.go, handlers_chat_v2.go: all callers updated to use ConversationEnvelopeSwitch. No data migration. The new key is absent on every existing hub, so every hub takes the compiled default (ON). Stale keys self-clean because handlePutMessaging rebuilds the document from the Go struct. Tests cover AC-9-7 (five stored states), AC-9-7a (stale-keys cutover), AC-9-7b (malformed logged once per refresh), AC-9-7c (PUT cleans stale keys), and AC-9-7d (null reset returns ON, not false). --- pkg/config/opsettings/opsettings_test.go | 3 +- pkg/config/opsettings/registry.go | 12 +- pkg/config/opsettings/sections.go | 16 +- pkg/hub/admin_messaging.go | 88 +++---- pkg/hub/admin_messaging_test.go | 279 +++++++++++++---------- pkg/hub/handlers_chat_v2.go | 4 +- pkg/hub/handlers_chat_v2_test.go | 10 +- pkg/hub/handlers_messages.go | 4 +- pkg/hub/handlers_read_switch_test.go | 6 +- pkg/hub/operational_settings.go | 47 ++-- pkg/hub/operational_settings_test.go | 106 ++++++--- pkg/hub/server.go | 9 +- 12 files changed, 336 insertions(+), 248 deletions(-) diff --git a/pkg/config/opsettings/opsettings_test.go b/pkg/config/opsettings/opsettings_test.go index d01ac166a7..23f60bad36 100644 --- a/pkg/config/opsettings/opsettings_test.go +++ b/pkg/config/opsettings/opsettings_test.go @@ -143,8 +143,7 @@ func TestMaintenanceHasNoOwnedKeys(t *testing.T) { func TestMessagingHasNoOwnedKeys(t *testing.T) { keys := []string{ - "messaging.conversation_read_switch", - "messaging.conversation_write_deny_switch", + "messaging.conversation_envelope_switch", } for _, key := range keys { if sec := OwningSection(key); sec != "" { diff --git a/pkg/config/opsettings/registry.go b/pkg/config/opsettings/registry.go index 2665626f23..71c3d4ffe1 100644 --- a/pkg/config/opsettings/registry.go +++ b/pkg/config/opsettings/registry.go @@ -314,14 +314,16 @@ func compileSchemas() { }, "additionalProperties": false, }, - // messaging schema is hand-written — conversation_read_switch and - // conversation_write_deny_switch are runtime/DB state with no $defs in - // settings-v1.schema.json. + // messaging schema is hand-written — conversation_envelope_switch is + // runtime/DB state with no $defs in settings-v1.schema.json. + // The stale keys (conversation_read_switch, conversation_write_deny_switch) + // are deliberately absent: additionalProperties:false rejects them on + // write, and existing rows carrying them are never validated (Validate + // runs only on write paths).

Without detection, this falls through to the compiled default (ON), silently enabling the switch on a hub where an operator made a typo. Fix: at Refresh/Update time, after json.Valid passes, also unmarshal into the section's typed struct via the registry's New function. If that fails, set Malformed=true and log at ERROR with the unmarshal error. Generic to all sections. (2) nil-ops GET divergence. handleGetMessaging returned ON when OperationalSettings was nil, but enforcement sites read `ops != nil && ops.ConversationEnvelopeSwitch()` → OFF. The admin endpoint was reporting a switch state that was not in effect. Fix: default to false (what enforcement does) when ops is nil. (3) Count accuracy noted — no code change needed. 4 files changed: operational_settings.go (+24), operational_settings_test.go (+31), admin_messaging.go (+4 -3), admin_messaging_test.go (+8 -10). --- pkg/hub/admin_messaging.go | 7 ++++--- pkg/hub/admin_messaging_test.go | 18 +++++++--------- pkg/hub/operational_settings.go | 24 +++++++++++++++++++++ pkg/hub/operational_settings_test.go | 31 ++++++++++++++++++++++++++++ 4 files changed, 67 insertions(+), 13 deletions(-) diff --git a/pkg/hub/admin_messaging.go b/pkg/hub/admin_messaging.go index 830a172a2c..252c23ca15 100644 --- a/pkg/hub/admin_messaging.go +++ b/pkg/hub/admin_messaging.go @@ -53,10 +53,11 @@ type messagingResponse struct { } // handleGetMessaging returns the current messaging switch. -// When no DB row exists (or OperationalSettings is nil), the compiled -// default is returned (ON). +// Reports what enforcement sites would actually do: when OperationalSettings +// is nil (init failed), enforcement reads `ops != nil && ops.…()` → false, +// so the GET must report false too — not the compiled default. func (s *Server) handleGetMessaging(w http.ResponseWriter) { - envelopeSwitch := true // compiled default: ON + envelopeSwitch := false // nil ops → same as enforcement: OFF if ops := s.GetOperationalSettings(); ops != nil { envelopeSwitch = ops.ConversationEnvelopeSwitch() diff --git a/pkg/hub/admin_messaging_test.go b/pkg/hub/admin_messaging_test.go index 4dc2bf5cd1..6590f0c74d 100644 --- a/pkg/hub/admin_messaging_test.go +++ b/pkg/hub/admin_messaging_test.go @@ -317,13 +317,11 @@ func TestHandleAdminMessaging_PutRecordsUpdatedBy(t *testing.T) { // route metadata entry exists below. func TestHandleAdminMessaging_GetNilOperationalSettings(t *testing.T) { - // GET with nil OperationalSettings (init failed) → switch ON (compiled default). - // This is the fail-closed guard for the nil-ops case: if initOperationalSettings - // errors out and the hub boots without OperationalSettings, the GET endpoint - // still returns the compiled default.

(cr-dev-a)" Date: Wed, 2 Sep 2026 03:37:05 +0000 Subject: [PATCH 028/105] feat(hub): stamp DeliveryText at all five send paths behind envelope switch (Phase 9b-iii) Stamp DeliveryText from RenderDeliveryText at each send-path call site, gated behind writeDenyEnabled (the consolidated envelope switch): Path 1 (handleAgentMessage): after persist, before dispatch. Path 2 (deliverToAgent/messagebroker): after persist, before dispatch. Path 3 (handleBrokerInbound): before dispatch (this path dispatches before persist). Pre-generates message UUID so the envelope carries a real identifier. Persist-failure log enriched with message_id, conversation_id, agent_id per Decision 4. Path 4 (handleChatV2): after persist, before dispatch, including mention fan-out with per-recipient stamp. Path 5 (broadcastDirect): inside fan-out loop, ConvResult nil. processMentions: ConvResult deliberately nil. The parent conversation IS resolved in the caller but is NOT propagated because mention targets are not known participants (disclosure concern). Group case unresolved, out of scope for Phase 9b. --- pkg/hub/handlers_agent_messaging.go | 44 +++++++++++++++++++++++++++++ pkg/hub/handlers_broker_inbound.go | 38 ++++++++++++++++++++++--- pkg/hub/handlers_chat_v2.go | 27 ++++++++++++++++++ pkg/hub/messagebroker.go | 17 ++++++++++- 4 files changed, 121 insertions(+), 5 deletions(-) diff --git a/pkg/hub/handlers_agent_messaging.go b/pkg/hub/handlers_agent_messaging.go index 57574b213f..af779cbf33 100644 --- a/pkg/hub/handlers_agent_messaging.go +++ b/pkg/hub/handlers_agent_messaging.go @@ -1120,6 +1120,17 @@ func (s *Server) handleAgentMessage(w http.ResponseWriter, r *http.Request, id s s.events.PublishUserMessage(ctx, storeMsg) messaging.RecordStep(ctx, "sse_published") } + + // Phase 9b(ii): render the delivery envelope from the persisted row + // and conversation result when the envelope switch is ON. + if s.writeDenyEnabled() && persistedMsgID != "" { + structuredMsg.DeliveryText = messaging.RenderDeliveryText(messaging.RenderDeliveryInput{ + MessageID: storeMsg.ID, + ConvResult: convResult, + Msg: structuredMsg, + CreatedAt: storeMsg.CreatedAt, + }) + } } // Managed agent path: deliver message directly via backend, bypass broker. @@ -1803,6 +1814,18 @@ func (s *Server) broadcastDirect(w http.ResponseWriter, r *http.Request, project s.messageLog.Error("Failed to persist broadcast message", "agent_id", agent.ID, "error", err) } + // Phase 9b(ii): render the delivery envelope for this broadcast + // recipient.

PersistedIdentity handles both: MessageID flows through, and empty ReplyToID means omit. - Change convInfo from ConversationInfo value to *ConversationInfo pointer: nil when ConvResult is nil, &convInfo when present. This connects to commit 2's omitempty change so nil ConvResult truly omits the conversation key from the JSON (was emitting zero struct). - Fix doc comment that claimed nil ConvResult omits the conversation key — that was false at 9b's HEAD (value type, no omitempty). Now true. - Update tests: nil-ConvResult tests now verify the key is absent from JSON (not just empty-string fields).

Any round trip through the old format lost the urgent flag. - ConversationID (string) → old.ConversationID: the field exists on both types but the reverse mapper never carried it. The round-trip test (TestRoundTrip_NewToOldToNew) could not catch either gap because every Message field was at its zero value or left unpopulated.

Three changes: 1. Propagate the real error. groupForMessage now returns (*group, error) instead of bare *group. Each result.Errors entry names the actual cause (dm_key_parse, dm_key_not_canonical, thread_no_project, or principal_pair) with the message ID. 2. Fix hazardA classification. The non-UUID principal counter was set AFTER a successful derive, but non-UUID principals cause case-4 (principal_pair) to fail — so the counter structurally could not see the population it existed to measure. Now counted at the derive-failure site. 3. Add per-cause breakdown. DeriveFailures map[string]int on BackfillResult reports how many messages failed for each of the four derivation causes, replacing 11,593 identical strings with four counters. DeriveConversationKey now returns *DeriveError (implements error) with a Cause field. All existing callers use the error interface unchanged. Nothing that currently fails is made to succeed. Nothing is written to the database differently — persistGroup is untouched, and the changes are entirely in the error-reporting branch that skips messages with continue. Attributed counts are identical before and after: verified by running the full backfill and attribution test suites. No build tags needed — all new tests use in-memory mocks and are visible to the blocking gate (go test -tags no_sqlite ./...). --- pkg/messaging/backfill.go | 56 ++++++++-- pkg/messaging/backfill_test.go | 173 ++++++++++++++++++++++++++++++- pkg/messaging/derive_key.go | 30 +++++- pkg/messaging/derive_key_test.go | 82 +++++++++++++++ 4 files changed, 322 insertions(+), 19 deletions(-) diff --git a/pkg/messaging/backfill.go b/pkg/messaging/backfill.go index 01a368d03f..14afe940d4 100644 --- a/pkg/messaging/backfill.go +++ b/pkg/messaging/backfill.go @@ -48,8 +48,12 @@ type BackfillResult struct { Inferred int `json:"inferred"` Skipped int `json:"skipped"` ConversationsCreated int `json:"conversationsCreated"` - HazardAEmailCount int `json:"hazardAEmailCount"` - HazardBSlugCount int `json:"hazardBSlugCount"` + HazardAEmailCount int `json:"hazardAEmailCount"` + HazardBSlugCount int `json:"hazardBSlugCount"` + // DeriveFailures counts refused messages by cause (DEF-114).

Store-level tests (dry-run no-mutate, execute re-key, idempotence, kind-encoded no-op, full flag wiring) require SQLite. --- cmd/server_dm_migration.go | 205 +++++++++++++++++ cmd/server_dm_migration_safety_test.go | 104 +++++++++ cmd/server_dm_migration_test.go | 295 +++++++++++++++++++++++++ 3 files changed, 604 insertions(+) create mode 100644 cmd/server_dm_migration.go create mode 100644 cmd/server_dm_migration_safety_test.go create mode 100644 cmd/server_dm_migration_test.go diff --git a/cmd/server_dm_migration.go b/cmd/server_dm_migration.go new file mode 100644 index 0000000000..1777283aa3 --- /dev/null +++ b/cmd/server_dm_migration.go @@ -0,0 +1,205 @@ +// 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. + +package cmd + +import ( + "context" + "fmt" + "io" + "strings" + + "github.com/GoogleCloudPlatform/scion/pkg/config" + "github.com/GoogleCloudPlatform/scion/pkg/ent/entc" + "github.com/GoogleCloudPlatform/scion/pkg/messaging" + "github.com/GoogleCloudPlatform/scion/pkg/store" + "github.com/GoogleCloudPlatform/scion/pkg/store/entadapter" + "github.com/spf13/cobra" +) + +var ( + dmMigrationExecute bool + dmMigrationBatchSize int + dmMigrationDB string +) + +var serverDMMigrationCmd = &cobra.Command{ + Use: "migrate-dm-keys", + Short: "Migrate DM conversation keys to kind-encoded format", + Long: `Scan direct conversations and migrate old-format external_ref keys +(dm::) to the kind-encoded format +(dm::::). + +By default runs in DRY-RUN mode — scans and reports what would change +without modifying the database.

From 23a2a1160ca7cb5d7c1bfa85bb2b75bfb91b4b78 Mon Sep 17 00:00:00 2001 From: "Scion Agent (cr-dev-a)" Date: Wed, 2 Sep 2026 05:58:59 +0000 Subject: [PATCH 049/105] fix: address review fixes F1-F4 for migration markers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit F1: MarkMigrationComplete now takes a typed MigrationName constant and returns ErrUnknownMigration for unrecognised names, preventing silent livelock from a typo that writes to a wrong key. F2: Internal representation changed from migrationsDoc struct to map[string]json.RawMessage, preserving unknown sibling keys across read-modify-write cycles (forward/backward compatibility for rollback binaries that may write newer markers). F3: TestAdvisoryLockKeys_AllUnique now reads concurrency.go from disk, regex-extracts all AdvisoryLockKey declarations, and asserts both uniqueness and completeness — replacing the hardcoded count that never actually caught drift. F4: Removed ProjectsDone field from migrationMarker (declared but never written by anything). Test changes: - All marker tests updated to use MigrationDMKey/MigrationBackfill constants - Added TestMigrationMarker_UnknownWriteReturnsError (F1 write-path) - Added TestMigrationMarker_PreservesUnknownSiblingKeys (F2 preservation) - Replaced TestMigrationMarker_UnknownMigrationName (read-only) with the write-path test --- cmd/migration_markers.go | 141 ++++++++++++++++++-------------- cmd/migration_markers_test.go | 148 ++++++++++++++++++++++++---------- pkg/store/concurrency_test.go | 74 ++++++++++++----- 3 files changed, 240 insertions(+), 123 deletions(-) diff --git a/cmd/migration_markers.go b/cmd/migration_markers.go index d77b6200e4..30573d5266 100644 --- a/cmd/migration_markers.go +++ b/cmd/migration_markers.go @@ -29,14 +29,16 @@ import ( // the _meta sentinel precedent (cmd/server_foreground.go:2078). const migrationsSectionName = "_migrations" -// migrationsDoc is the JSON structure persisted in the _migrations section. -// Each field is a pointer so that absent keys unmarshal as nil rather than -// zero-value structs, letting IsMigrationComplete distinguish "never run" -// from "run with a zero-time completion." -type migrationsDoc struct { - DMKeyMigration *migrationMarker `json:"dm_key_migration,omitempty"` - MessageBackfill *migrationMarker `json:"message_backfill,omitempty"` -} +// MigrationName is a typed constant for migration identifiers, so that a +// typo in a migration name is a compile error rather than a silent no-op +// that produces a permanent livelock (marker never written, migration +// retries every boot, making no progress). +type MigrationName string + +const ( + MigrationDMKey MigrationName = "dm_key_migration" + MigrationBackfill MigrationName = "message_backfill" +) // migrationMarker records the completion state of a single migration. // @@ -46,9 +48,8 @@ type migrationsDoc struct { // prevent marker creation — M-1' distinguishes "the pass did not happen" // from "the pass happened and some rows are permanent non-participants." type migrationMarker struct { - CompletedAt *time.Time `json:"completed_at"` // nil => not yet complete - Residuals int `json:"residuals,omitempty"` // row-level refusals (permanent, non-retryable) - ProjectsDone []string `json:"projects_done,omitempty"` // backfill only: per-project progress + CompletedAt *time.Time `json:"completed_at"` // nil => not yet complete + Residuals int `json:"residuals,omitempty"` // row-level refusals (permanent, non-retryable) } // IsMigrationComplete returns true if the named migration has a completion @@ -56,17 +57,25 @@ type migrationMarker struct { // a malformed document, or a missing/null CompletedAt are all treated as // "not complete" — which means the migration will be retried, and that is // always the safe direction. -func IsMigrationComplete(ctx context.Context, s store.Store, name string) (bool, error) { - doc, err := loadMigrationsDoc(ctx, s) +func IsMigrationComplete(ctx context.Context, s store.Store, name MigrationName) (bool, error) { + _, raw, err := loadMigrationsDoc(ctx, s) if err != nil { return false, err } - if doc == nil { + if raw == nil { + return false, nil + } + + entry, ok := raw[string(name)] + if !ok { return false, nil } - marker := doc.markerFor(name) - return marker != nil && marker.CompletedAt != nil, nil + var marker migrationMarker + if err := json.Unmarshal(entry, &marker); err != nil { + return false, nil // malformed entry: safe direction is retry + } + return marker.CompletedAt != nil, nil } // MarkMigrationComplete records that the named migration's full pass completed. @@ -79,17 +88,28 @@ func IsMigrationComplete(ctx context.Context, s store.Store, name string) (bool, // deterministic and non-retryable).

"Scion Agent (cr-dev-a)" Date: Wed, 2 Sep 2026 06:53:48 +0000 Subject: [PATCH 052/105] feat(cmd): add boot-time DM key migration hook (M4) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wire the DM key migration into the hub boot sequence via runBootDataMigrations, replacing the maybeWarnUnbackfilledMessages call site at server_foreground.go:1218. The migration runs synchronously under the LockDataMigrations advisory lock, before the hub serves any request, so "migrations done" and "switch on" are not two independently observable states (design §4.1, F3). Marker semantics follow M-1' (not superseded M-1): - Run-level failure (cannot list, cannot write, context cancelled): the pass did not happen. Log ERROR, do NOT write the marker. Next boot retries. - Row-level refusal (deterministic, non-retryable per-row outcome): the pass completed. Count the refusal, persist the count as a residual in the marker, write the marker. Next boot skips. The distinction is load-bearing: on production data the migration produces thousands of deterministic row-level refusals that no retry can change. Blocking the marker on those refusals would create a permanent livelock (design §4.3). The existing backfill warning still fires after the DM migration — re- pointing it is M6, not this commit. No new operator switch is added. Boot is never blocked by a failing migration. Error log output is bounded to maxBootLogErrors (10) entries plus a total count, preventing an unbounded result.Errors list from turning a bad migration into a disk-space incident. --- cmd/boot_data_migrations.go | 149 +++++++ cmd/boot_data_migrations_safety_test.go | 73 ++++ cmd/boot_data_migrations_test.go | 491 ++++++++++++++++++++++++ cmd/server_foreground.go | 2 +- 4 files changed, 714 insertions(+), 1 deletion(-) create mode 100644 cmd/boot_data_migrations.go create mode 100644 cmd/boot_data_migrations_safety_test.go create mode 100644 cmd/boot_data_migrations_test.go diff --git a/cmd/boot_data_migrations.go b/cmd/boot_data_migrations.go new file mode 100644 index 0000000000..8f0dc956c4 --- /dev/null +++ b/cmd/boot_data_migrations.go @@ -0,0 +1,149 @@ +// 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. + +package cmd + +import ( + "context" + "fmt" + "log/slog" + + "github.com/GoogleCloudPlatform/scion/pkg/messaging" + "github.com/GoogleCloudPlatform/scion/pkg/store" +) + +// maxBootLogErrors is the maximum number of per-row error messages logged +// during a boot-time migration. result.Errors holds one entry per refused +// row and is unbounded; logging it whole turns a bad migration into a +// disk-space incident (design §4.3).

The marker was absent because the write was impossible, not because the guard refused it. Removing the `return` after the run-level error check — the exact bug AC-2b exists to catch — still passed. Fix: replace the cancelled-context approach with a store wrapper (listConversationsFailStore) that errors on ListConversations while leaving the marker-writing path (GetHubSetting / UpsertHubSetting) fully functional on a live context. Also add a defensive nil guard on result after the M-1' decision point, so the mutation test exposes a clean assertion failure ("marker must not be written for a pass that did not complete") rather than a nil-pointer panic. Mutation-tested: removing the `return` after the run-level error check now produces: Error: Should be false Messages: M-1': run-level failure must NOT write the marker; next boot must retry The marker IS written for a pass that did not complete, and the test catches it. --- cmd/boot_data_migrations.go | 9 +++++ cmd/boot_data_migrations_test.go | 57 ++++++++++++++++++++++++-------- 2 files changed, 52 insertions(+), 14 deletions(-) diff --git a/cmd/boot_data_migrations.go b/cmd/boot_data_migrations.go index 8f0dc956c4..cec8563aaa 100644 --- a/cmd/boot_data_migrations.go +++ b/cmd/boot_data_migrations.go @@ -97,6 +97,15 @@ func runDMKeyMigration(ctx context.Context, s store.Store) { // The pass completed.

This is the second of two data migrations that auto-run on hub upgrade, per design §4.5. Behaviour: - Enumerate projects exactly as the CLI (cmd/server_backfill.go) does. - Skip projects already in the marker's projects_done list. - Run the backfill per project. On a completed pass (M-1': run-level success; row-level refusals do NOT disqualify), append that project to projects_done and persist immediately. - Check the time budget (default 10 minutes, measured per OQ-1) after each project. If exhausted, stop; the next boot resumes at the first project not in projects_done. - When every enumerated project is done, set completed_at and clear projects_done (bounded growth). Subsequent boots do a single marker read — O(1) with respect to data volume. M-1' is the crux: a run-level failure (could not list projects, store write error, context cancelled) means the pass did not happen — log ERROR, do not record that project as done. Row-level refusals are terminal, correct, permanent outcomes. On gteam the backfill produces 11,593 deterministic refusals against 24,700 messages and attributes 6,476. If row refusals blocked the marker, every boot would re-run a 37-second migration forever, making no progress. That is a livelock, not safety. Also updates two M4 tests whose messages are now attributed by the backfill: seed unattributable messages (non-UUID principals, no ThreadID) so the warning-still-fires assertions remain valid. Mutation results (all captured from real runs): 1. Remove `return` after ListProjects error → test TestBootBackfill_RunLevelFailure_NoMarker FAILS (marker written for a pass that did not happen). Guard effective. 2. Remove `continue` after per-project run-level error → test TestBootBackfill_PerProjectRunLevelFailure PANICS (nil deref on result). Guard effective. 3. Remove `return` after completed_at fast path → test TestBootBackfill_AlreadyComplete FAILS (migration starts when already complete). Guard effective. 4. Disable budget check → test TestBootBackfill_BudgetExhaustion FAILS (all projects complete instead of stopping). Guard effective. --- cmd/boot_backfill_test.go | 675 +++++++++++++++++++++++++++++++ cmd/boot_data_migrations.go | 209 +++++++++- cmd/boot_data_migrations_test.go | 40 +- cmd/migration_markers.go | 64 +++ 4 files changed, 973 insertions(+), 15 deletions(-) create mode 100644 cmd/boot_backfill_test.go diff --git a/cmd/boot_backfill_test.go b/cmd/boot_backfill_test.go new file mode 100644 index 0000000000..a61f126093 --- /dev/null +++ b/cmd/boot_backfill_test.go @@ -0,0 +1,675 @@ +// 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.

Design alternative A2 rejected blocking boot on a data migration failure; an unrecovered panic is a harder version of that outcome. Each migration is wrapped individually — not as a pair — so a panic in the DM key migration does not prevent the backfill from running, and vice versa. On panic, the marker is NOT written: a panicking pass did not complete, which is a run-level failure under M-1'. The recover is a scoped abort, not a rollback. Already-persisted projects_done entries are committed to the store before the panic and remain intact. A subsequent boot resumes from where it left off. Three new tests: - BackfillPanic_Contained: panic in backfill is caught, DM migration still runs and completes, backfill marker absent, DM marker present. - DMKeyPanic_BackfillStillRuns: panic in DM migration is caught, backfill still runs and completes. - PanicPreservesProgress: pre-seed two projects as done, panic on the third.

This count is expected to be stable and does not warrant operator action. - WARN (only when reachable > 0): messages in listed projects that remain unattributed — the only count that operator action can reduce. This replaces the old maybeWarnUnbackfilledMessages which fired a single WARN for all unattributed messages and advertised "scion server backfill --execute" — stale advice after auto-run. Store layer: adds CountUnreachableUnbackfilledMessages to MessageStore, using a NOT EXISTS anti-join against the projects table. The sum-of- per-project-counts approach (design §4.6 original preference) is not viable because M5's per-project resumption skips all projects on a steady-state boot, producing no per-project counts to sum. CONSEQUENCE: the DEF-112 drift concern is now live. The counter's predicate and the backfill's skip predicate must share one expression. This makes M7 required, not optional. Acceptance criterion 9 test covers: - First boot: reachable message attributed, orphan reported as unreachable at INFO, WARN does not fire, no backfill command advertised - Steady-state: second boot with zero backfill work, both counts still correct, WARN still does not fire All four mutations tested and caught (detailed in report to ca-msg-arch). --- cmd/boot_backfill_test.go | 20 ++- cmd/boot_data_migrations.go | 78 ++++++++++- cmd/boot_data_migrations_test.go | 182 +++++++++++++++++++++++-- cmd/server_attribution_report.go | 6 +- cmd/server_foreground.go | 1 - cmd/server_foreground_backfill_test.go | 23 +++- pkg/messaging/backfill_test.go | 6 + pkg/store/entadapter/message_store.go | 28 ++++ pkg/store/store.go | 12 ++ 9 files changed, 323 insertions(+), 33 deletions(-) diff --git a/cmd/boot_backfill_test.go b/cmd/boot_backfill_test.go index d48f4cc188..151c162c4a 100644 --- a/cmd/boot_backfill_test.go +++ b/cmd/boot_backfill_test.go @@ -675,9 +675,17 @@ func TestBackfillMarker_PreservesSiblingKeys(t *testing.T) { // Warning still fires after backfill // --------------------------------------------------------------------------- -// TestBootBackfill_WarningStillFires verifies that the existing backfill -// warning still fires after the backfill completes (re-pointing is M6). -func TestBootBackfill_WarningStillFires(t *testing.T) { +// TestBootBackfill_ReachableWarnFires verifies that the split residual +// report emits a WARN for reachable unattributed messages after the +// backfill completes (M6 re-pointed the old warning).

On gteam the WARN prints ~12,606 — twice the orphan count M6 suppressed — because "everything else" conflates derive refusals and broadcast messages with genuinely actionable failures. M9 separates permanently unattributable messages into their own INFO bucket so the WARN fires only for actionable drift. Design (§4.8 second correction): permanent is measured, not tallied. After each project's backfill pass, CountUnbackfilledMessages(pid) is taken as a pure measurement — no tally subtraction. Transient failures (write + resolution) are accumulated separately and reported as their own WARN line. This prevents the tally/measurement mixing that caused two successive off-by errors during design review. Arithmetic: total = CountUnbackfilledMessages("") unreachable = CountUnreachableUnbackfilledMessages() reachable = total - unreachable permanent = marker.PermanentResidual (measured, persisted) actionable = max(0, reachable - permanent) transient = marker.TransientFailures (tallied, persisted) Report: INFO unreachable, INFO permanent, WARN actionable (only >0), WARN transient (only >0, with retry remedy). Pre-M9 marker handling: a completed marker lacking PermanentResidual triggers a one-time idempotent re-run to write the new format. Accumulator reset: counters reset to zero at the start of a pass beginning with empty projects_done (prevents double-count on repeat).

M9 added a pre-M9 marker upgrade path that clears CompletedAt and re-runs the full pass — over a marker that already has a populated Residuals. This caused total_residuals to double-count: prior pass's residuals plus this pass's residuals. Evidence: on gteam boot 1, reported total_residuals=23,190 which is exactly 11,593 (this pass) + 11,597 (previous pass). The fix gives totalResiduals the same reset semantics as the M9 accumulators: reset at the start of a pass that begins with empty ProjectsDone; carry forward only within a genuinely resumed pass. The shared "resume or reset" predicate is factored into a single boolean.

The resulting short permanent count produces a spurious actionable WARN that no operator action can clear — DEF-111's exact shape. The fix detects this marker shape before building doneSet and promotes it to a fresh pass: clear ProjectsDone and Residuals, re-run all projects. Re-running is safe and cheap (idempotent backfill, ~37s on gteam). M9-format resumption (PermanentResidual present) is preserved. Also updates TestBootBackfill_Resumption_MonotonicProgress and TestBootBackfill_PanicPreservesProgress fixtures to use M9-format markers so they test genuine M9 resumption, not pre-M9 mid-pass. Gate G4: pre-M9 mid-pass marker promotion — permanent equals true still-NULL count, actionable WARN absent, all projects re-run, total_residuals identity holds. --- cmd/boot_backfill_test.go | 25 +++--- cmd/boot_data_migrations.go | 30 +++++-- cmd/boot_m9_test.go | 155 ++++++++++++++++++++++++++++++++++++ 3 files changed, 194 insertions(+), 16 deletions(-) diff --git a/cmd/boot_backfill_test.go b/cmd/boot_backfill_test.go index 3404fbcde6..ba8f335aa3 100644 --- a/cmd/boot_backfill_test.go +++ b/cmd/boot_backfill_test.go @@ -441,10 +441,13 @@ func TestBootBackfill_Resumption_MonotonicProgress(t *testing.T) { pid3, _ := seedBackfillProjectWithMessage(t, ctx, s, "resume-p3") allPIDs := map[string]bool{pid1: true, pid2: true, pid3: true} - // Pre-seed one project as already done. + // Pre-seed one project as already done (M9-format: includes + // PermanentResidual so the marker is not promoted to a fresh pass). + priorPermanent := 0 err := saveBackfillProgress(ctx, s, backfillMarker{ - ProjectsDone: []string{pid1}, - Residuals: 5, + ProjectsDone: []string{pid1}, + Residuals: 5, + PermanentResidual: &priorPermanent, }) require.NoError(t, err) @@ -457,9 +460,9 @@ func TestBootBackfill_Resumption_MonotonicProgress(t *testing.T) { "all projects should be done") // G3 (M9a): exact value — the fixture pre-seeds Residuals=5 with pid1 - // already done. pid2 and pid3 each have one attributable message - // (UUID principals → derive succeeds, row_errors=0).

Mock-level tests assert counters, exact keys, and CheckDMParticipantKey outcomes. SQLite-backed tests assert isDMParticipant authorization outcomes for the security-relevant classes. Production changes: - Add DegeneratePairs counter to DMMigrationResult (observes, does not gate) - Add slog.Warn for degenerate self-DM pairs (preserves evidence) - Add kind-token ordering tripwire comment to golden vector tests FINDING: F-5 (identical UUIDs) reveals the migration has no distinctness check — it produces a self-DM ACL (dm:user:X:user:X) from dm:X:X. The DegeneratePairs counter preserves the evidence. Whether to refuse these rows is an open product question, not addressed here. --- cmd/dm_migration_adversarial_test.go | 358 ++++++++++++++++++++++ pkg/messages/dm_key_test.go | 14 + pkg/messaging/dm_migration.go | 12 + pkg/messaging/dm_migration_test.go | 436 +++++++++++++++++++++++++++ 4 files changed, 820 insertions(+) create mode 100644 cmd/dm_migration_adversarial_test.go diff --git a/cmd/dm_migration_adversarial_test.go b/cmd/dm_migration_adversarial_test.go new file mode 100644 index 0000000000..fd89c10fef --- /dev/null +++ b/cmd/dm_migration_adversarial_test.go @@ -0,0 +1,358 @@ +// 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 ( + "context" + "testing" + + "github.com/GoogleCloudPlatform/scion/pkg/messages" + "github.com/GoogleCloudPlatform/scion/pkg/messaging" + "github.com/GoogleCloudPlatform/scion/pkg/store" + "github.com/google/uuid" + "github.com/stretchr/testify/assert" + "github.com/stretchr/testify/require" +) + +// --------------------------------------------------------------------------- +// Adversarial fixture-class tests — sqlite-backed authorization assertions +// +// These tests exercise the must-NOT-repair and must-repair authorization +// outcomes against a real store.

The old code could never observe a collision. Replaced with exact UUID/email resolution that eliminates the ambiguity vector entirely. P2: `user:` resolution now requires the token to be either a valid UUID (direct GetUser lookup) or contain `@` (exact email lookup, case-folded). Display-name substring matching (`LIKE '%token%'`) is removed — display_name has no uniqueness constraint and the old query silently picked the newest row. P3: Three typed refusal codes — ADDR_UNKNOWN (0 matches), ADDR_AMBIGUOUS (>1 matches, reserved), ADDR_MALFORMED (not UUID, not email) — with error messages that name a working alternative form. OQ-A2: In group[]/set[] sends, any member that fails to resolve refuses the entire send. No partial delivery. AC-A3 mutation gate verified: reverting to `len(Items)==1` compiles and turns AC-A1 red (200 instead of 400).

charset=UTF-8 Content-Transfer-Encoding: 8bit Review item 1: GetUserByEmail uses Only(), which returns NotSingularError when >1 row matches (legacy mixed-case emails). The first revision collapsed this into ADDR_UNKNOWN ("No user exists") — a false statement when two users exist. Now: - mapError maps ent.NotSingular → store.ErrNotSingular (new sentinel) - Email branch checks ErrNotSingular → ADDR_AMBIGUOUS (400) - Test: raw-SQL seeded duplicate-case emails, asserts addr_ambiguous and that neither user received a message. Review item 2: All error branches now distinguish three conditions: - store.ErrNotFound → ADDR_UNKNOWN (400, "No user exists") - store.ErrNotSingular → ADDR_AMBIGUOUS (400, "Multiple users match") - anything else → 500 internal_error, logged at error level Applied uniformly at both call sites (outbound and group handler), on both UUID and email branches. Review item 3 (@agent form measurement): tested against base commit 97c3462ab — same 400 failure: "principal_kind must be user or agent, got system". Pre-existing, not a DEF-126 regression. Root cause: buildPrincipalRef (envelope_compat.go:224-226) — when recipient "@target-agent" has no colon, it defaults to PrincipalRef("system:" + name). This is a separate defect in the legacy envelope conversion; the @ form was never functional through ValidateLegacyMessage's addressee validation path.

S3a (thread path) keeps its 409 — thread conversations are created by the topic system, so absence there is genuine drift.

Participant filter fails open: non-manage + nil UserIdentity left ParticipantID empty → unscoped query. Fixed: deny (403) when the caller is not-manage and no user identity can be resolved. Absence of identity now produces less access, not more. 2. Authorization-denial audit log dropped: replacing s.authorize() with direct CheckAccess lost the logAuthzDenial call. Restored: the read- denial path now calls logAuthzDenial before writing the 403. 3. Privacy filter coupled to LogID: the ParticipantID constraint was conditional on opts.LogID == logging.MessageLogID. An access-control constraint must not be conditional on a log-routing value. Fixed: ParticipantID applies unconditionally when set. Tests added: - TestDEF128b_NonManageNonUser_Denied: synthetic non-user identity gets 403, not an unscoped query - TestDEF128b_ParticipantFilter_Unconditional: ParticipantID emitted for all LogID values including empty - TestDEF128b_MutationTest_Compiling: scoped vs unscoped filter inequality + constraint presence assertions --- pkg/hub/handlers_def127_128_test.go | 120 ++++++++++++++++++++++++++++ pkg/hub/handlers_logs.go | 21 +++-- pkg/hub/logquery.go | 14 ++-- pkg/hub/logquery_test.go | 14 +++- 4 files changed, 156 insertions(+), 13 deletions(-) diff --git a/pkg/hub/handlers_def127_128_test.go b/pkg/hub/handlers_def127_128_test.go index 8384fe80c3..60a881dfab 100644 --- a/pkg/hub/handlers_def127_128_test.go +++ b/pkg/hub/handlers_def127_128_test.go @@ -25,11 +25,14 @@ package hub // DEF-127 — thread path still returns 409 (covered in handlers_read_switch_test.go) import ( + "context" "encoding/json" "net/http" + "net/http/httptest" "strings" "testing" + "github.com/GoogleCloudPlatform/scion/pkg/api" "github.com/GoogleCloudPlatform/scion/pkg/messaging" "github.com/GoogleCloudPlatform/scion/pkg/store" ) @@ -212,3 +215,120 @@ func TestDEF128b_ParticipantFilter_MutationTest(t *testing.T) { t.Errorf("unscoped filter should not contain user-456: %q", withoutParticipant) } } + +// --------------------------------------------------------------------------- +// DEF-128b defect #1: non-manage + no user identity → deny (fail closed) +// --------------------------------------------------------------------------- + +// nonUserIdentity is a minimal Identity that does NOT implement UserIdentity. +// This simulates a caller kind (future or synthetic) that passes basic +// authentication but is not a user — testing the fail-closed guard. +type nonUserIdentity struct { + id string +} + +func (n *nonUserIdentity) ID() string { return n.id } +func (n *nonUserIdentity) Type() string { return "synthetic" } + +func TestDEF128b_NonManageNonUser_Denied(t *testing.T) { + // A non-manage caller with no UserIdentity must be denied (403), not + // served an unscoped query.

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.

Fix: force effectiveConv = nil when req.Message.Broadcasted, after precedence resolution.

P-2: Authorize caller-supplied ConversationID on the outbound handler. Port the DEF-49 authorization block with direction-aware docstrings: the agent is the SENDER (not recipient), so group-case asserts "the conversation belongs to the sending agent's project." Parse failure denies, always. Never normalise a DM key — a differing round-trip is an error, not a rewrite. P-3: deliverToUser honours a pre-resolved ConversationID from the upstream handler instead of re-deriving. This is the edit that makes explicit routing actually take effect — without it the handler's resolution was discarded when the broker was present, producing the inbound/outbound conversation split.

New fields such as `conversation_id` may appear in message metadata but are not yet required for correct agent behavior. +**Conversation routing:** Inbound messages carry a `conversation` field in the delivery envelope that identifies the conversation they belong to.

Fixed by adding a distinct explicit-routing outcome (LogExplicitRouting) with its own counter that bypasses ComputeDivergenceMatch entirely. BLOCKER 2: AC-6 not met — LogDivergence fired twice per outbound reply (once in the handler, once in deliverToUser). Removed the handler's divergence block and consistency check; the broker's deliverToUser handles both at persistence time. Guard expected count updated 7→6. New test: TestDEF138_ExplicitRouting_NeverCountedAsMismatch exercises deliverToUser with a pre-resolved ConversationID and asserts DivergenceMetrics.Mismatches() does not increase. Mutation-verified: replacing LogExplicitRouting body with DivergenceMetrics.Inc(false) keeps the build green but fails the test. --- pkg/hub/consistency_check_guard_test.go | 2 +- pkg/hub/handlers_agent_messaging.go | 27 +--- pkg/hub/handlers_outbound_def138_test.go | 159 ++++++++++++++++++++++- pkg/hub/messagebroker.go | 44 ++++--- pkg/messaging/divergence.go | 33 +++++ 5 files changed, 224 insertions(+), 41 deletions(-) diff --git a/pkg/hub/consistency_check_guard_test.go b/pkg/hub/consistency_check_guard_test.go index 23df267113..497d180ab5 100644 --- a/pkg/hub/consistency_check_guard_test.go +++ b/pkg/hub/consistency_check_guard_test.go @@ -100,7 +100,7 @@ func TestConsistencyCheckReturnConsumed(t *testing.T) { // Assert the expected count of call sites so that a NEW unguarded site // also trips this test — the developer must update this count and // verify the new site consumes the return. - const expectedCallSites = 7 + const expectedCallSites = 6 if totalCallSites != expectedCallSites { t.Errorf("expected %d CheckConversationConsistency call sites in non-test "+ "pkg/hub sources, found %d.

This violates R3. Add ChannelToSurface() as the single mapping function: - Valid surface names (discord, slack, telegram, gchat, teams, native) pass through directly. - "web" maps explicitly to "native" (web-chat is the native surface). - Unknown/empty channels fall back to "native" with a WARN log. - All three call sites now use ChannelToSurface() instead of raw channel.

Main's authorization refactor (a61cddd63) removed the policy concept and renamed createProjectMembersGroupAndPolicy -> createProjectMembersGroup, updating every call site it could see. Tranche-g had three it could not: two in handlers_broker_inbound_test.go and def135_test.go (files both branches edited) and one in a tranche-g-only test file. Git merged both sides cleanly. handlers_broker_inbound_test.go ended up with four call sites on the new name from main's rename and one on the old name from tranche-g, in the same file, with no conflict raised. Pure rename: identical signature (ctx, project *store.Project, callerUserID ...string), same defining file, and all three sites pass only (ctx, project). Why this got through: `go build ./...` passes because only TEST code referenced the old name, and the blocking CI gate is `make test-fast` (-tags no_sqlite), which excludes these files. Verified now with `go vet ./...` over the whole tree, which compiles test files in every package and reports zero errors. --- pkg/hub/handlers_broker_inbound_def135_test.go | 4 ++-- pkg/hub/handlers_broker_inbound_test.go | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/pkg/hub/handlers_broker_inbound_def135_test.go b/pkg/hub/handlers_broker_inbound_def135_test.go index ce627a56cf..ad3688f8cc 100644 --- a/pkg/hub/handlers_broker_inbound_def135_test.go +++ b/pkg/hub/handlers_broker_inbound_def135_test.go @@ -147,7 +147,7 @@ func setupDEF135(t *testing.T) def135Fixture { Updated: time.Now(), } require.NoError(t, s.CreateProject(ctx, project)) - srv.createProjectMembersGroupAndPolicy(ctx, project) + srv.createProjectMembersGroup(ctx, project) msgAuthzAddProjectMember(t, s, user.ID, project.ID, project.Slug, store.GroupMemberRoleMember) agent := &store.Agent{ @@ -500,7 +500,7 @@ func TestDEF135_AC5_WriteDeny409_DispatcherNeverCalled(t *testing.T) { Updated: time.Now(), } require.NoError(t, s2.CreateProject(ctx, project2)) - srv2.createProjectMembersGroupAndPolicy(ctx, project2) + srv2.createProjectMembersGroup(ctx, project2) msgAuthzAddProjectMember(t, s2, user2.ID, project2.ID, project2.Slug, store.GroupMemberRoleMember) agent2 := &store.Agent{ diff --git a/pkg/hub/handlers_broker_inbound_test.go b/pkg/hub/handlers_broker_inbound_test.go index 9b03e2ff44..c6323d138c 100644 --- a/pkg/hub/handlers_broker_inbound_test.go +++ b/pkg/hub/handlers_broker_inbound_test.go @@ -656,7 +656,7 @@ func TestHandleBrokerInbound_ConvResolutionFailure_WriteDenyOff(t *testing.T) { Updated: time.Now(), } require.NoError(t, s.CreateProject(ctx, project)) - srv.createProjectMembersGroupAndPolicy(ctx, project) + srv.createProjectMembersGroup(ctx, project) msgAuthzAddProjectMember(t, s, user.ID, project.ID, project.Slug, store.GroupMemberRoleMember) agent := &store.Agent{ From ffe96f03ec5f859d1f75813e2d0eff05260e6488 Mon Sep 17 00:00:00 2001 From: "Scion Agent (ca-msg-convref)" Date: Mon, 7 Sep 2026 04:16:16 +0000 Subject: [PATCH 101/105] fix(hub): allow conv: and #thread refs without explicit recipient (DEF-152) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The guard at line 210 in handleAgentOutboundMessage rejected any request with an empty recipient BEFORE the conversation_ref resolver at line 334 could run. Since conv:, #, and @ references carry no explicit recipient by design, they were always rejected with "recipient is required." Changes: - Relax the guard: requests with a conversation_ref but no recipient now pass through to the resolver. Requests with NEITHER are still 400 with the original error message. - After conversation resolution + DEF-138 authorization, derive the addressee from the resolved conversation's DM key for direct conversations. For group conversations (no single addressee), refuse explicitly rather than guessing. - Security: the addressee is derived from the conversation's participant set (the DM key), never from request input. Non-user addressees (agent-to-agent DMs) are refused on this user-delivery endpoint. Tests added: 1. conv: with no recipient → 2xx, correct recipient derived from DM key (the missing test that would have caught this). 2. # with no recipient → clear refusal for group conversations. 3. Neither recipient nor conversation_ref → still 400, message unchanged. 4. Conversation the sender is not a participant of → refused, no disclosure of project IDs. 5.

Added: - TestDEF152_SenderOnSideB_DerivedAddresseeStillCorrect: uses a hand-crafted DM key with the user on side A and the agent on side B. Under mutation 1, the test fails (400 instead of 200: "non-user addressee"). - TestDEF152_NonUserAddressee_AgentToAgentDM_Refused: sends conv: pointing to an agent-to-agent DM. Under mutation 2, the test fails (500 instead of 400: user lookup fails for agent ID). --- pkg/hub/handlers_outbound_def152_test.go | 121 +++++++++++++++++++++++ 1 file changed, 121 insertions(+) diff --git a/pkg/hub/handlers_outbound_def152_test.go b/pkg/hub/handlers_outbound_def152_test.go index 357273ef50..71c9338039 100644 --- a/pkg/hub/handlers_outbound_def152_test.go +++ b/pkg/hub/handlers_outbound_def152_test.go @@ -290,3 +290,124 @@ func TestDEF152_ConvRef_WithRecipient_StillWorks(t *testing.T) { require.Equal(t, http.StatusOK, rr.Code, "providing both recipient and conversation_ref must still work") } + +// --------------------------------------------------------------------------- +// DEF-152 mutation coverage 1: sender on the OTHER side of the DM key. +// +// DMConversationKey sorts tokens lexicographically.

The flags remain registered (hidden, using BoolP) so cobra parses them without an "unknown flag" error, but they are no longer bound to package-level variables. Changes: - Remove msgBroadcast/msgAll variables and all conditional branches - Clean up sendMessageViaHub signature: remove dead broadcast/all params - Remove local-mode broadcast dispatch (fan-out, WaitGroup, etc.) - Remove Broadcasted field from buildStructuredMessage (only cmd/broadcast.go and server-side handleProjectBroadcast set it now) - Remove unused imports (state, config) - Reword conv:/# ref error messages to be unmistakably by-design: state the positive case (works inside an agent container where SCION_AGENT_NAME is set) - Update tests: remove broadcast/all test functions, update call signatures, fix Changed state cleanup across test isolation - Update docs (cli.md, messaging.md, SKILL.md) Security: server-side Broadcasted=true forcing in handleProjectBroadcast is untouched (verified by check-security-marker-gates). --- cmd/message.go | 215 ++-------- cmd/message_convref_test.go | 6 +- cmd/message_deprecation_test.go | 134 +++---- cmd/message_test.go | 371 +++--------------- .../src/content/docs/hosted/user/messaging.md | 2 +- docs-site/src/content/docs/reference/cli.md | 4 +- .../platform_skills/scion-messaging/SKILL.md | 2 +- 7 files changed, 135 insertions(+), 599 deletions(-) diff --git a/cmd/message.go b/cmd/message.go index 9721b30fa3..4bbb1301c8 100644 --- a/cmd/message.go +++ b/cmd/message.go @@ -27,9 +27,7 @@ import ( "time" "github.com/GoogleCloudPlatform/scion/pkg/agent" - "github.com/GoogleCloudPlatform/scion/pkg/agent/state" "github.com/GoogleCloudPlatform/scion/pkg/api" - "github.com/GoogleCloudPlatform/scion/pkg/config" "github.com/GoogleCloudPlatform/scion/pkg/hubclient" "github.com/GoogleCloudPlatform/scion/pkg/messages" "github.com/GoogleCloudPlatform/scion/pkg/messaging" @@ -38,8 +36,6 @@ import ( ) var msgInterrupt bool -var msgBroadcast bool -var msgAll bool var msgIn string var msgAt string var msgPlain bool @@ -64,8 +60,6 @@ var deprecationReplacements = []struct { Flag string Message string }{ - {"broadcast", "use 'scion broadcast' instead"}, - {"all", "use 'scion broadcast --all' instead"}, {"raw", "use 'scion keys' instead"}, {"plain", "--plain is deprecated and will be removed"}, {"notify", "use 'scion notifications subscribe' instead"}, @@ -103,8 +97,6 @@ Recipients: conv: Send to a conversation by ID # Send to a named thread -If --broadcast is used, the recipient can be omitted and the message will be sent to all running agents. - Examples: scion message my-agent "Please review the PR" scion message @my-agent "Please review the PR" @@ -123,6 +115,14 @@ Examples: } } + // Refuse removed flags with actionable errors. + if cmd.Flags().Changed("broadcast") { + return fmt.Errorf("--broadcast has been removed from 'scion message';

This replaces the old `--raw` flag on `scion message`. ## Discord diff --git a/docs-site/src/content/docs/reference/cli.md b/docs-site/src/content/docs/reference/cli.md index ab98d19867..63da43cc4f 100644 --- a/docs-site/src/content/docs/reference/cli.md +++ b/docs-site/src/content/docs/reference/cli.md @@ -137,8 +137,6 @@ Sends a message to a running agent or user. - `--plain`: *(Deprecated — will be removed.)* Mark for plain-text delivery. - `--channel `: *(Deprecated — use conversation addressing instead.)* Target a specific message channel (e.g., `telegram`, `gchat`, `teams`, `web`). - `--thread-id `: *(Deprecated — use conversation addressing instead.)* Target a specific thread ID within the channel. - - `-b, --broadcast`: *(Deprecated — use `scion broadcast` instead.)* - - `-a, --all`: *(Deprecated — use `scion broadcast --all` instead.)* - `--raw`: *(Deprecated — use `scion keys` instead.)* Send literal bytes via tmux send-keys with no trailing Enter. - `--in `: *(Deprecated — use `scion schedule create --in` instead.)* Schedule message delivery after a duration. - `--at
