From ad1ff1281f9a18d1bae4f4443319ba81008fe0a4 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 27 Apr 2026 08:52:34 +0000 Subject: [PATCH 1/8] docs: spec for optional stream bootstrap across services Seven services unconditionally call CreateOrUpdateStream at startup; in prod, streams are pre-provisioned by ops/IaC.

Extend that convention to the seven services above. + +## Goals + +- Local dev (`docker-compose` against the local NATS container) continues to create streams automatically so a developer can stand up any service in isolation. +- Production deployments do not call `CreateOrUpdateStream` at all.

Gating preserves current "any service starts standalone in dev" behavior. A future cleanup can collapse to owner-only bootstrap, matching `search-sync-worker`'s stated philosophy. +- Changing how `search-sync-worker` works — it already has the pattern. +- Pre-flight checks that warn if a stream is missing before consumer creation. If `BOOTSTRAP_STREAMS=false` and the stream doesn't exist, `CreateOrUpdateConsumer` will fail at startup with the underlying NATS error. That fail-fast behavior is desired — it surfaces a missing IaC provision step. + +## Design + +### Config struct + +Each of the seven services adds the following to its `config` (in `main.go`): + +```go +// bootstrapConfig groups every field that is ONLY meaningful when the +// service is being stood up in dev or integration tests against a NATS +// instance where the streams it consumes do not yet exist. In +// production streams are pre-provisioned by ops/IaC and Bootstrap.Enabled +// must remain false; the service only creates its own durable consumer. +type bootstrapConfig struct { + // Enabled (BOOTSTRAP_STREAMS) toggles whether the service calls + // CreateOrUpdateStream at startup for the streams it consumes. + // Leave false in production. + Enabled bool `env:"STREAMS" envDefault:"false"` +} + +type config struct { + // ...existing fields... + Bootstrap bootstrapConfig `envPrefix:"BOOTSTRAP_"` +} +``` + +Env var: `BOOTSTRAP_STREAMS`. Default: `false`. + +### Gated stream creation + +Each existing `js.CreateOrUpdateStream` call is wrapped in a check on `cfg.Bootstrap.Enabled`. To make the gate independently unit-testable, extract a small helper per service: + +```go +// bootstrapStreams creates the streams this service consumes from. +// In production this is a no-op (cfg.Bootstrap.Enabled is false) — streams +// are owned by ops/IaC. In dev/integration the local docker-compose sets +// BOOTSTRAP_STREAMS=true so a developer can stand the service up in +// isolation against a fresh NATS instance. +func bootstrapStreams(ctx context.Context, js streamCreator, siteID string, enabled bool) error { + if !enabled { + return nil + } + canonicalCfg := stream.MessagesCanonical(siteID) + if _, err := js.CreateOrUpdateStream(ctx, jetstream.StreamConfig{ + Name: canonicalCfg.Name, + Subjects: canonicalCfg.Subjects, + }); err != nil { + return fmt.Errorf("create MESSAGES_CANONICAL stream: %w", err) + } + return nil +} + +// streamCreator is the minimal interface the helper depends on, kept +// service-local so we don't pollute pkg/ with a one-method type. +type streamCreator interface { + CreateOrUpdateStream(ctx context.Context, cfg jetstream.StreamConfig) (jetstream.Stream, error) +} +``` + +`main.go` calls the helper before consumer creation: + +```go +if err := bootstrapStreams(ctx, js, cfg.SiteID, cfg.Bootstrap.Enabled); err != nil { + slog.Error("bootstrap streams failed", "error", err) + os.Exit(1) +} + +cons, err := js.CreateOrUpdateConsumer(ctx, canonicalCfg.Name, jetstream.ConsumerConfig{ ... }) +``` + +The shape of `bootstrapStreams` varies per service: + +- `message-gatekeeper` creates two streams (`MESSAGES`, `MESSAGES_CANONICAL`) — both gated together. +- `broadcast-worker`, `message-worker`, `notification-worker` each create `MESSAGES_CANONICAL`. +- `room-worker`, `room-service` each create `ROOMS`. +- `inbox-worker` creates `INBOX`. + +Each helper lives in the same `package main` as the service and uses the service-local `streamCreator` interface. This keeps the test seam minimal and avoids any new shared package. + +### Consumer creation is unaffected + +`CreateOrUpdateConsumer` calls remain unconditional. A service always owns its consumer regardless of who owns the stream. + +### Local dev — docker-compose + +Each of the seven services has `deploy/docker-compose.yml`. Add `BOOTSTRAP_STREAMS=true` to the service's `environment:` block: + +```yaml +services: + : + environment: + # ...existing env vars... + BOOTSTRAP_STREAMS: "true" +``` + +Production manifests stay unchanged — the absent env var means default `false`. + +### Tests (TDD) + +Per CLAUDE.md, every change follows Red-Green-Refactor. + +For each of the seven services, add a unit test in `main_test.go` (creating the file if it does not exist) that table-tests the new helper: + +```go +func TestBootstrapStreams(t *testing.T) { + tests := []struct { + name string + enabled bool + wantCreated []string // stream names expected to be created + }{ + {"disabled - skips creation", false, nil}, + {"enabled - creates expected streams", true, []string{"MESSAGES_CANONICAL_test"}}, + } + for _, tc := range tests { + t.Run(tc.name, func(t *testing.T) { + fake := &fakeStreamCreator{} + err := bootstrapStreams(t.Context(), fake, "test", tc.enabled) + require.NoError(t, err) + require.Equal(t, tc.wantCreated, fake.created) + }) + } +} +``` + +The fake `streamCreator` records which stream names it was asked to create. No mockgen-generated mock is needed — the interface has one method and the helper is service-local. + +For `bootstrapStreams` calls that fail, add an additional table case where the fake returns an error and assert the helper wraps it with `fmt.Errorf("create stream: %w", err)`. + +Coverage target per CLAUDE.md: ≥80% for the helper. The helper has only two paths (enabled false, enabled true with each stream) plus error wrapping, so reaching the threshold is straightforward. + +### Doc updates + +Add a short subsection to `CLAUDE.md` under "JetStream Streams": + +> **Stream bootstrap is opt-in.** Services that consume from a stream do NOT create it in production — streams are owned by ops/IaC. Each service's `config` includes `Bootstrap bootstrapConfig` with `BOOTSTRAP_STREAMS` (default `false`). Local docker-compose files set it to `true` so any service can stand up against a fresh NATS in dev. New services that consume from JetStream MUST follow this convention. + +## Migration + +No data migration. The change is config-only. Rollout per service: + +1. Land code change with default `false`. +2. Verify prod manifests do not set `BOOTSTRAP_STREAMS=true` (they shouldn't, since they don't reference it today). Streams are already provisioned in prod, so the effective behavior shift is "service no longer touches the stream config" — strictly safer. +3. Local dev compose files are updated in the same PR so `make` workflows continue to function. + +## Open Questions + +None. Decisions confirmed: + +- `room-service` is in scope (publisher-only, but same prod concern). +- Test strategy is unit-only via the extracted helper; integration tests already cover the `Enabled=true` end-to-end path indirectly. +- Existing redundant stream creations (`MESSAGES_CANONICAL` in three workers, `ROOMS` in two services) are preserved and gated; collapsing to owner-only bootstrap is a future cleanup.

From d90a962e4370b47c0ca15d8b474f4e52ba8b4d40 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 27 Apr 2026 10:01:00 +0000 Subject: [PATCH 3/8] feat: gate JetStream stream creation behind BOOTSTRAP_STREAMS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Streams in production are pre-provisioned by ops/IaC. Services should only create their own consumers, not the streams themselves. Extend the existing search-sync-worker BOOTSTRAP_STREAMS convention to every service that calls CreateOrUpdateStream at startup. Each affected service grows a service-local bootstrap.go with: - bootstrapConfig{ Enabled bool } env:"STREAMS" envDefault:"false" - streamCreator interface (one method, oteljetstream.Stream return) - bootstrapStreams(ctx, js, siteID, enabled) error helper main.go wraps the existing CreateOrUpdateStream call(s) inside the helper and gates them on cfg.Bootstrap.Enabled. Consumer creation is unchanged and stays unconditional.

From 153eaa02e8a828da998cba33fa522c70b638e4c0 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 27 Apr 2026 12:03:18 +0000 Subject: [PATCH 6/8] refactor(streams): inbox-worker owns INBOX schema; remove search-sync-worker scaffolding inbox-worker is now the sole owner of INBOX_{siteID} schema bootstrap. Its bootstrapStreams helper passes Name + Subjects from pkg/stream.Inbox, matching the canonical schema. Federation (Sources + SubjectTransforms) remains owned by ops/IaC and never appears in app code. search-sync-worker stops bootstrapping INBOX. The dead scaffolding inboxBootstrapStreamConfig (originally added with PR #109 and flagged in its own doc comment as a temporary stand-in until inbox-worker migrated) is deleted along with its dedicated unit-test file. The RemoteSiteIDs config field is removed since its only consumer was the deleted function. The service's bootstrap loop now skips INBOX while continuing to create consumers for INBOX-based collections (spotlight, user-room). CLAUDE.md gains an explicit ownership rule under "JetStream Streams" documenting that app code owns Name + Subjects and ops/IaC owns Sources + SubjectTransforms. Tests: inbox-worker bootstrap test now asserts Subjects matches pkg/stream.Inbox(siteID).Subjects and Sources is empty (regression guard against re-introducing federation in app code). https://claude.ai/code/session_015Cu3UPeWDU4DaJwP7JZtvc --- CLAUDE.md | 1 + inbox-worker/bootstrap.go | 18 +++++----- inbox-worker/bootstrap_test.go | 17 +++++---- search-sync-worker/inbox_stream.go | 47 ++----------------------- search-sync-worker/inbox_stream_test.go | 47 ------------------------- search-sync-worker/main.go | 47 ++++++++++--------------- 6 files changed, 43 insertions(+), 134 deletions(-) delete mode 100644 search-sync-worker/inbox_stream_test.go diff --git a/CLAUDE.md b/CLAUDE.md index 74f68a690..3a2cfe0d6 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -216,6 +216,7 @@ All commands are wrapped in the root Makefile.

When BOOTSTRAP_STREAMS=false (production path), the helper calls js.Stream() to verify each stream exists. A missing stream returns an error that main.go converts to a clean exit with a log line, so a misprovisioned deploy surfaces at startup instead of at first publish. The streamCreator interface is widened to streamManager (adds Stream method). The fake test double is renamed to fakeStreamManager and gains an existing map so tests can simulate "stream not found" cleanly. Each service's TestBootstrapStreams gains a "disabled - verifies existing stream" case (replacing the old "skips creation" case) and a "disabled - fails when stream missing" case asserting both the wrap message and errors.Is(err, jetstream.ErrStreamNotFound). https://claude.ai/code/session_015Cu3UPeWDU4DaJwP7JZtvc --- broadcast-worker/bootstrap.go | 43 ++++++++++++-------- broadcast-worker/bootstrap_test.go | 38 ++++++++++++++---- inbox-worker/bootstrap.go | 39 ++++++++++-------- inbox-worker/bootstrap_test.go | 38 ++++++++++++++---- message-gatekeeper/bootstrap.go | 58 +++++++++++++++++---------- message-gatekeeper/bootstrap_test.go | 50 ++++++++++++++++++----- message-worker/bootstrap.go | 43 ++++++++++++-------- message-worker/bootstrap_test.go | 38 ++++++++++++++---- notification-worker/bootstrap.go | 43 ++++++++++++-------- notification-worker/bootstrap_test.go | 38 ++++++++++++++---- room-service/bootstrap.go | 43 ++++++++++++-------- room-service/bootstrap_test.go | 38 ++++++++++++++---- room-worker/bootstrap.go | 43 ++++++++++++-------- room-worker/bootstrap_test.go | 38 ++++++++++++++---- 14 files changed, 415 insertions(+), 175 deletions(-) diff --git a/broadcast-worker/bootstrap.go b/broadcast-worker/bootstrap.go index 560a764f3..b63ba7f56 100644 --- a/broadcast-worker/bootstrap.go +++ b/broadcast-worker/bootstrap.go @@ -23,28 +23,39 @@ type bootstrapConfig struct { Enabled bool `env:"STREAMS" envDefault:"false"` } -// streamCreator is the minimal JetStream surface bootstrapStreams depends on. -// Kept service-local so we don't pollute pkg/ with a one-method type and so +// streamManager is the minimal JetStream surface bootstrapStreams depends on. +// Kept service-local so we don't pollute pkg/ with a multi-method type and so // tests can inject a fake without mockgen. -type streamCreator interface { +type streamManager interface { CreateOrUpdateStream(ctx context.Context, cfg jetstream.StreamConfig) (oteljetstream.Stream, error) + Stream(ctx context.Context, name string) (oteljetstream.Stream, error) } -// bootstrapStreams creates the JetStream streams this service consumes from. -// No-op when enabled is false (the production path) — streams are owned by -// ops/IaC.
