From 74e269c8737661f7d0b3d7cbd82b80da3f97a1d4 Mon Sep 17 00:00:00 2001 From: Muhammad Ahmed Cheema Date: Sun, 26 Apr 2026 22:37:25 -0700 Subject: [PATCH 1/4] agent: tenancy heartbeat + synthetic first DM (B.1.4) Adds two best-effort POSTs the in-VM Phantom fires to phantomd's metadata gateway after the boot's key milestones: 1. After router.register(slackChannel) in src/index.ts, POST /v1/tenant_status/agent_ready with the configured transport. phantom-control's WaitTenantReady RPC unblocks; the wizard advances out of the waiting_for_agent_ready phase. 2. After SlackHttpChannel.connect() succeeds, send the synthetic introduction DM to the installer (the user moment the canary is gated on), then POST /v1/tenant_status/first_dm_sent with the Slack message_ts. phantomd persists tenants.first_dm_at so phantom-control can flip applications.status=active. Wire shape matches phantomd's tenant_status_handler.go exactly: agent_ready accepts only { transport: "..." }; first_dm_sent accepts only { slack_message_ts: "..." }. Source-IP authn is enforced by the gateway, so we do not sign or pass any tenant identifier. Best-effort posture per architect plan section 8.3 / 8.4: a network or non-2xx failure logs and continues. METADATA_BASE_URL gates both heartbeats so self-host installs (where there is no listener) skip silently. The first DM is gated by an instance-level firstDmSent flag, so a transient disconnect+reconnect on the same channel object does not re-introduce the agent. A process restart resets the flag; the canary's worse-case is a duplicate intro DM after a hard restart, preferable to silent UX failure when the user never sees a first message. The introduction copy + send logic lives in src/channels/slack-introduction.ts (separate module so slack-http-receiver.ts stays close to its 300-line budget; mirrors slack-egress.ts factoring). Tests added (~397 LoC): - src/tenancy/__tests__/heartbeat.test.ts (8 tests): URL shape, body shape, trailing-slash handling, non-2xx swallow, fetch rejection swallow, empty-ts skip. - src/channels/__tests__/slack-introduction.test.ts (9 tests): text composition, sendDm wiring, heartbeat ack, METADATA_BASE_URL gate, sendDm-returns-null path, sendDm-throws path, token redaction. - src/channels/__tests__/slack-http-receiver.test.ts (4 tests): end-to-end DM on connect, reconnect dedup, failure does not break connect, retry on fresh connect after first send returned no ts. --- .../__tests__/slack-http-receiver.test.ts | 69 +++++++ .../__tests__/slack-introduction.test.ts | 170 ++++++++++++++++++ src/channels/slack-http-receiver.ts | 20 +++ src/channels/slack-introduction.ts | 94 ++++++++++ src/index.ts | 15 ++ src/tenancy/__tests__/heartbeat.test.ts | 158 ++++++++++++++++ src/tenancy/heartbeat.ts | 112 ++++++++++++ 7 files changed, 638 insertions(+) create mode 100644 src/channels/__tests__/slack-introduction.test.ts create mode 100644 src/channels/slack-introduction.ts create mode 100644 src/tenancy/__tests__/heartbeat.test.ts create mode 100644 src/tenancy/heartbeat.ts diff --git a/src/channels/__tests__/slack-http-receiver.test.ts b/src/channels/__tests__/slack-http-receiver.test.ts index 74727f3..babce2d 100644 --- a/src/channels/__tests__/slack-http-receiver.test.ts +++ b/src/channels/__tests__/slack-http-receiver.test.ts @@ -624,6 +624,71 @@ describe("lifecycle and bot user discovery", () => { }); }); +// ----- synthetic first DM (Phase B.1.4) ----------------------------------- + +describe("synthetic first DM on connect", () => { + test("opens a DM with the installer and posts the introduction text", async () => { + const channel = new SlackHttpChannel(baseConfig); + channel.setPhantomName("Maple"); + await channel.connect(); + + // installerUserId is U_INSTALLER per baseConfig; conversations.open is + // called once for the introduction.

SLACK_TRANSPORT === "http" is the actual signal that the agent is in an HTTP-transport deployment with a host metadata gateway listening; METADATA_BASE_URL alone misses the case where the channel factory falls back to the link-local default. Fixed both call sites in src/index.ts and src/channels/slack-introduction.ts; both now also fall back to DEFAULT_METADATA_BASE_URL so an unset env is not a gating failure. Section B: heartbeat.test.ts refactored away from the mock(...) as unknown as FetchImpl cast pattern. The wrapper carries internal reset state that has shifted across Bun minor versions and broke a single sibling test on Bun 1.3.13 (passes locally on 1.3.5). Replaced makeFetchOk / makeFetchStatus / makeFetchThrows with plain async functions typed directly as FetchImpl. No mock() involvement, no cast, no per-runtime state. Should pass on every Bun release. Section D: dashboard URL is now parameterized. composeIntroductionText accepts an optional dashboardUrl, dropping the "manage me" line entirely when unset. sendIntroductionDm reads PHANTOM_DASHBOARD_URL via a resolveDashboardUrl helper that validates with new URL(...) and drops a malformed value with a warning rather than injecting unparseable text into the user-facing DM. Caller in phantom-rootfs sets the env var so cloud deployments get the cloud URL; self-hosters with no env var see a shorter, valid DM. Section D (continued): scrubbed internal milestone references from every comment new in the diff. "Phase B.1.4" prefixes dropped, "the canary user" rephrased to "the user", "phantomd" replaced with "the host metadata gateway" or "the host gateway", "architect plan section 12 (option A)" replaced with an inline description of the contract. The diff against main now matches zero internal-data leak patterns under the orchestrator's grep. Tests: - New slack-introduction tests assert the SLACK_TRANSPORT-based gate: unset / socket = no heartbeat, http = heartbeat with default URL when METADATA_BASE_URL is unset, http = heartbeat with set URL when both are set. Plus three new dashboard-URL tests covering valid URL, unset, and malformed. - New heartbeat tests exercise the same FetchImpl signature without mock(); existing assertions intact. Gates: bun lint clean, bun typecheck clean, 1957 / 1957 tests pass. --- .../__tests__/slack-http-receiver.test.ts | 10 +- .../__tests__/slack-introduction.test.ts | 120 ++++++++++++++++-- src/channels/slack-http-receiver.ts | 24 ++-- src/channels/slack-introduction.ts | 90 ++++++++----- src/index.ts | 24 ++-- src/tenancy/__tests__/heartbeat.test.ts | 35 +++-- src/tenancy/heartbeat.ts | 52 ++++---- 7 files changed, 251 insertions(+), 104 deletions(-) diff --git a/src/channels/__tests__/slack-http-receiver.test.ts b/src/channels/__tests__/slack-http-receiver.test.ts index babce2d..5d0568b 100644 --- a/src/channels/__tests__/slack-http-receiver.test.ts +++ b/src/channels/__tests__/slack-http-receiver.test.ts @@ -624,7 +624,7 @@ describe("lifecycle and bot user discovery", () => { }); }); -// ----- synthetic first DM (Phase B.1.4) ----------------------------------- +// ----- synthetic first DM on connect --------------------------------------- describe("synthetic first DM on connect", () => { test("opens a DM with the installer and posts the introduction text", async () => { @@ -673,10 +673,10 @@ describe("synthetic first DM on connect", () => { test("retries the introduction on a fresh connect after first send returned null", async () => { // First connect: chat.postMessage returns no ts (rate-limit, archived - // channel). firstDmSent stays false; the wizard's failed_first_dm + // channel). firstDmSent stays false; the caller's failed_first_dm // path is what surfaces this externally.

F-B14-E (P2): index.ts read process.env.SLACK_TRANSPORT verbatim before the agent_ready heartbeat. readSlackTransportFromEnv() trims its input, so a whitespace-padded SLACK_TRANSPORT=" http " booted the HTTP receiver while the gate skipped reportAgentReady, leaving the operator's readiness RPC waiting indefinitely. The factory and the gate now share the same normalized transport via the helper. F-B14-F (P2): slack-introduction.ts had the same raw-env mismatch on the first_dm_sent gate. Same helper applied here so a successful Slack DM is always paired with the audit signal in HTTP-transport boots. CI test: heartbeat.test.ts "POSTs to ..." tests for both reportAgentReady and reportFirstDmSent rewritten to use a globalThis.fetch override with scalar locals (no closure-captured array). The previous pattern passed on Bun 1.3.5 locally but failed on Bun 1.3.13 in CI; the rewrite is Bun-version-agnostic and the try/finally restore is mandatory so a mid-test failure does not leak the override into sibling tests. Tests: 1959 pass, 10 skip, 0 fail.
