# SCRATCHPAD: Teams Diagnostics + Proactive Test Message

Plan slug: `2026-05-29-teams-diagnostics-test-message`
Created: 2026-05-29

## Why this is the next PR (rationale)

- Observability loop (`2026-05-24-teams-observability-loop`, PR #2562, F001–F050) shipped the data substrate: `teams_notification_deliveries`, `teams_audit_events`, `teams_conversation_references`. Nothing *reads* deliveries or conversation references yet.
- Diagnostics + test message is the natural consumer of that substrate, and it's the gating blocker for charging (admin self-verification without logs).
- The test message is built on the **proactive bot path**, which lights up the dormant `teams_conversation_references` table and validates the exact transport Phase 2 channel delivery will reuse — so a cheap Phase 1 win also de-risks Phase 2.

## Key code discoveries (verified)

### Proactive send already exists
- `ee/packages/microsoft-teams/src/lib/teams/bot/teamsBotConnector.ts`
  - `sendBotActivity({ serviceUrl, conversationId, replyToId?, activity })` — POSTs to `{serviceUrl}/v3/conversations/{id}/activities`. THE proactive primitive. Already used for synchronous bot replies at `teamsBotHandler.ts:1219`.
  - `isBotConnectorConfigured()` / `readBotCredentialsFromEnv()` — creds from env `TEAMS_BOT_APP_ID`, `TEAMS_BOT_APP_TENANT_ID`, `TEAMS_BOT_APP_PASSWORD`.
  - `isTrustedServiceUrl()` — suffix allowlist guard, applied inside sendBotActivity.
  - Token: client-credentials grant, scope `https://api.botframework.com/.default`, cached.
  - Returns `{status:'sent'|'skipped', reason?}`; throws on non-OK HTTP. **Decision:** test message treats `skipped` as a skip outcome and a thrown error as a `failed` delivery row.
- Env vars already wired in `helm/templates/deployment.yaml` and `helm/templates/secret.yaml`.

### Conversation references: written, never read
- `ee/packages/microsoft-teams/src/lib/teams/bot/teamsConversationReferences.ts`
  - `upsertTeamsConversationReference(...)` — only writer. Called from `teamsBotHandler.ts:988` on every inbound activity.
  - Type `TeamsConversationReferenceType = 'personal' | 'groupChat' | 'channel'`.
  - NO reader exists yet → F001 adds it (first consumer of the table).
- Table (`ee/server/migrations/20260524090200_create_teams_conversation_references.cjs`):
  - PK `(tenant, microsoft_user_id, conversation_id)`; cols `service_url`, `conversation_type`, `tenant_id_aad`, `channel_id_bot_framework`, `last_activity_at`, timestamps.
  - Distributed on `tenant`, colocated with `teams_integrations`.

### Deliveries table — reusable, no migration needed
- `ee/server/migrations/20260524090000_create_teams_notification_deliveries.cjs`
  - `category` is **nullable, no CHECK** → `category='test'` is safe.
  - `status` CHECK ∈ {skipped, sent, delivered, failed}. Test uses skipped/sent/failed.
  - `destination_type` free text NOT NULL. Existing real value is `'user_activity'` (`teamsNotificationDelivery.ts:261`). Test uses `'bot_test'`.
  - `error_code` CHECK against `DELIVERY_ERROR_CODES` enum — **check whether 'transient'/existing codes cover test failures, or whether error_code should be left NULL for test sends.** (Recorder: `teamsDeliveryRecorder.ts`.)
  - UNIQUE `(tenant, idempotency_key)` → include attempt nonce for repeated tests (F012/T017).
- Recorder: `ee/packages/microsoft-teams/src/lib/notifications/teamsDeliveryRecorder.ts` — reuse `recordTeamsNotificationDelivery`-style insert; check its exact input shape (`destinationType`, `category`, `status`, `idempotencyKey`).

### Delivery / mapping helpers
- `teamsNotificationDelivery.ts:321 resolveTeamsRecipientLink(tenant, userId)` → `{ providerAccountId }` (the Microsoft account-link `provider_account_id`). Used as the Graph `users/{id}` id.

### Diagnostics pattern to mirror
- `shared/services/email/providers/MicrosoftGraphAdapter.ts:745 runMicrosoft365Diagnostics()`:
  - `runStep(id, title, fn)` → pushes `{id, title, startedAt, durationMs, status, http?, data?, error?}`; statuses `pass|fail|warn|skip`.
  - `recommendations` is a `Set<string>`; report has `createdAt`, `steps[]`, `overallStatus`, recommendations.
  - Reference test: `shared/services/email/providers/__tests__/MicrosoftGraphAdapter.diagnostics.test.ts`.
  - UI reference: `packages/integrations/src/components/email/admin/Microsoft365DiagnosticsDialog.tsx` (badge rendering pattern for steps).

### Availability / entitlement
- `ee/packages/microsoft-teams/src/lib/teams/teamsAvailability.ts`
  - `getTeamsAvailability({isEnterpriseEdition?, tenantId, userId})` → `{enabled, reason}`; reasons `ce_unavailable | tenant_not_configured | addon_required | enabled`.
  - addon check = `tenant_addons` where `addon_key = ADD_ONS.TEAMS` and (`expires_at` null or future).

### Action wiring pattern
- `ee/packages/microsoft-teams/src/lib/actions/integrations/teamsObservabilityActions.ts`: `export const listTeamsDeliveries = withAuth(listTeamsDeliveriesImpl);` (`'use server'`, `@alga-psa/auth/withAuth`). Mirror for `runTeamsDiagnostics` / `sendTeamsTestMessage`.
- Existing teams settings actions: `teamsActions.ts` → `saveTeamsIntegrationSettingsImpl` (line 225). **Confirm its permission check and reuse the same gate.**

### Settings UI
- `packages/integrations/src/components/settings/integrations/TeamsIntegrationSettings.tsx`
  - Uses `Card`/`CardHeader`/`CardContent` from `@alga-psa/ui`. Existing buttons have ids `teams-save-draft`, `teams-reload`, etc. Add new card after the package card (~line 602+).
  - `canPersist` style gating already present → reuse for disabling the new buttons (F032).

## Decisions

- **No new migration.** Reuse `teams_notification_deliveries` + `teams_conversation_references`.
- **Test message = proactive bot path** (`sendBotActivity`), NOT a Graph `sendActivityNotification`. This validates the Phase 2 transport and exercises the conversation-reference table.
- `destination_type='bot_test'`, `category='test'` for test delivery rows.
- Test message degrades to a recorded `skipped` row (with reason) for every unhealthy precondition — never silently no-ops.
- Diagnostics is read-only except for the recommendations it computes; no state mutation.
- Incremental settings panel, NOT the full 4-step wizard (that's a later PR).

## Resolved questions

1. **AAD object id vs bot `from.id` — RESOLVED (verified in code 2026-05-29).** The mapping aligns by design:
   - Write side: `teamsConversationReferences.ts:48-50` stores `microsoft_user_id = from.aadObjectId || from.id`. For a real Teams user, `aadObjectId` (AAD object id GUID) is populated.
   - Link side: `nextAuthOptions.ts:881-882` `extractProviderAccountId` returns `claims.oid` for Microsoft, with an explicit comment (878-883): "oid is the Azure AD object ID — the value Bot Framework sends as activity.from.aadObjectId ... prefer oid". So Microsoft `provider_account_id == oid == aadObjectId == microsoft_user_id`.
   - The bot's existing `resolveTeamsLinkedUser.ts:51` already depends on this (`findOAuthAccountLink('microsoft', aadObjectId)`), and it's shipped.
   - **Consequence:** drop the planned `resolveTeamsMicrosoftUserId` helper. Just reuse `resolveTeamsRecipientLink(tenant, userId).providerAccountId` (export it; currently file-private in `teamsNotificationDelivery.ts:321`) and key the F001 reader by it. (F003 updated.)
   - **Residual edge:** `ssoActions.ts:308` bulk email-backfill sets `provider_account_id = lowerEmail`. Microsoft links created that way won't match a conversation reference — but the bot already can't resolve those users. Diagnostics surfaces this via the F021/F022 warnings; out of scope to fix.

## Open questions (resolve during implementation)

1. **Permission gate** — exact permission enforced by `saveTeamsIntegrationSettingsImpl`; reuse verbatim.
3. **error_code for test failures** — reuse an existing `DELIVERY_ERROR_CODES` value or leave NULL? (CHECK constraint forbids arbitrary codes.)
4. **Where packages/integrations imports EE teams actions** — confirm the existing boundary/registry used so F037 follows it (CE has no EE package; check the stub pattern).

## 2026-05-29 implementation notes

### conversation-reader

- F001: Added `getLatestTeamsConversationReferenceImpl({ tenant, microsoftUserId, conversationType })` in `ee/packages/microsoft-teams/src/lib/teams/bot/teamsConversationReferences.ts`. It scopes through `createTenantKnex`, filters by `tenant`, `microsoft_user_id`, and `conversation_type`, defaults to `personal`, and orders by `last_activity_at DESC`.
- F002: Reader returns a typed `TeamsConversationReferenceRecord | null` and maps missing/blank input, empty result, or read failure to `null` with a warning for read failures.
- F003: Exported existing `resolveTeamsRecipientLink()` and `TeamsRecipientLink` from `teamsNotificationDelivery.ts`; this reuses the verified Microsoft `provider_account_id`/AAD oid as the conversation-reference key.
- F004: No extra barrel change was required for source exports because `ee/packages/microsoft-teams/src/lib/index.ts` already exports both `teamsConversationReferences` and `teamsNotificationDelivery`.
- T001-T004: Extended `server/src/test/unit/lib/teams/bot/teamsConversationReferences.test.ts` to cover newest-row selection, default/explicit conversation-type filtering, tenant scoping, and null return for no match.
- T005-T006: Updated stale checklist wording from the removed `resolveTeamsMicrosoftUserId` helper to `resolveTeamsRecipientLink`, then covered successful Microsoft-link resolution and null when no Microsoft link exists.

### test-message

- F005: Added `sendTeamsTestMessageImpl()` and `sendTeamsTestMessage = withAuth(...)` in `ee/packages/microsoft-teams/src/lib/actions/integrations/teamsDiagnosticsActions.ts`; it uses the same `system_settings:update` gate as `saveTeamsIntegrationSettingsImpl`.
- F006-F010: Implemented precondition skips for inactive add-on, inactive integration, disabled `personal_bot`, missing bot env credentials, missing Microsoft user linkage, and missing personal conversation reference. Each skip records a `teams_notification_deliveries` row before returning.
- F011: Healthy path builds a proactive bot test activity with text/card title `Alga PSA Teams test message` and sends it through `sendBotActivity()` using the stored `serviceUrl` and `conversationId`.
- F012: Extended `writeTeamsDeliveryRow()` to allow `destinationType='bot_test'`, nullable `internalNotificationId`, and an `idempotencyNonce`; test-message rows use `category='test'`, `destination_type='bot_test'`, and a per-click nonce so repeated tests insert distinct rows.
- T007-T018: Added `server/src/test/unit/lib/teams/actions/teamsDiagnosticsActions.test.ts` covering permission denial, every skip reason, happy-path proactive send payload, sent/failed delivery rows, distinct idempotency keys, and tenant-scoped reads/writes.
- Verification: `cd server && npx vitest run src/test/unit/internal-notifications/teamsDeliveryRecorder.test.ts src/test/unit/lib/teams/actions/teamsDiagnosticsActions.test.ts` passed 16 tests.

### diagnostics

- F013-F014: Added `TeamsDiagnosticsStep`, `TeamsDiagnosticsReport`, `TeamsDiagnosticsStatus`, and `runTeamsDiagnosticsImpl()` with ordered `runStep()` capture of status/detail/duration/data/error plus recommendation accumulation.
- F015-F024: Diagnostics now checks Teams add-on availability, integration status, required capabilities, Microsoft profile readiness, package metadata/base URL, bot connector env credentials, current admin Microsoft link, personal conversation reference, and tenant-scoped recent delivery health. Overall status rolls up fail > warn > pass and recommendations are deduped.
- T019-T033: Extended `server/src/test/unit/lib/teams/actions/teamsDiagnosticsActions.test.ts` with diagnostics coverage for permission denial, ordered steps, every required check, recent delivery tenant scoping, status aggregation, recommendation dedupe, and the fully healthy pass case.
- Verification: `cd server && npx vitest run src/test/unit/lib/teams/actions/teamsDiagnosticsActions.test.ts` passed 27 tests; `npm -w @alga-psa/ee-microsoft-teams run typecheck` passed.

### settings-ui

- F025-F032: Added a `Diagnostics & Test Message` card below the package card in `packages/integrations/src/components/settings/integrations/TeamsIntegrationSettings.tsx`. It wires `Run diagnostics` and `Send test message` actions, renders step badges, recommendations, recent delivery summary, mapped test-message results, loading/error state, and disables both buttons unless the integration is active.
- Boundary note: the UI needs the action imports through `packages/integrations/src/actions`; action re-exports and EE action-index export were added while implementing this panel and will be verified/marked in the later `wiring` group.
- T034-T039: Added `TeamsIntegrationSettings.diagnostics.test.tsx` covering step/status rendering, recommendations present/hidden, sent confirmation, missing-conversation-reference guidance, disabled states, and recent delivery summary.
- Verification: `cd server && npx vitest run ../packages/integrations/src/components/settings/integrations/TeamsIntegrationSettings.diagnostics.test.tsx` passed 6 tests (React act warnings emitted by async state updates); `npm -w @alga-psa/integrations run typecheck` passed.

## Out of scope (Phase 2+ — do NOT bundle)

- `teams_channel_mappings`, channel routing/delivery, expanded categories.
- `teams_user_preferences` / quiet hours / mention-only.
- Full setup wizard, configurable channel tab.
- 402/403 entitlement-response standardization.
- Trial flow / metering / billing.
- LLM/fuzzy bot intent, SSO token exchange.

## Suggested commit groups (≈7 commits)

`conversation-reader` → `test-message` → `diagnostics` → `settings-ui` → `i18n` → `wiring` → (tests land in each group's commit).

### i18n

- F033-F035: Added `integrations.teams.settings.diagnostics.*` locale keys to every `server/public/locales/*/msp/integrations.json` file. The diagnostics panel now localizes its section title/description, button labels, status labels, errors, test-message reason text, step titles, and recommendation strings with defaultValue fallbacks.
- T040-T041: Added `TeamsIntegrationSettings.i18n.test.ts` to assert every integrations locale contains the diagnostics keys and every test-message skip/fail reason maps to a defined key, preventing raw key leaks or unmapped reason codes.

### wiring

- F036-F037: Verified the EE action barrel exports `teamsDiagnosticsActions`, and `packages/integrations/src/actions` plus `packages/integrations/src/actions/integrations` re-export `runTeamsDiagnostics`, `sendTeamsTestMessage`, and their result types for `TeamsIntegrationSettings`. Added T042 coverage to `teamsActions.test.ts` so the boundary remains importable.
- F038/T043: Rebuilt `@alga-psa/ee-microsoft-teams` with `npm -w @alga-psa/ee-microsoft-teams run build`. Changed the package tsup config to bundle local source into dist entries because the non-bundled dist action barrel re-exported local paths that were not emitted. Verified `dist/actions/index.mjs` contains `runTeamsDiagnostics`, `sendTeamsTestMessage`, `runTeamsDiagnosticsImpl`, and `sendTeamsTestMessageImpl`. Direct Node import still depends on the broader monorepo package runtime state, so the smoke check is a built-file export check after the successful build.
- Verification: `cd server && npx vitest run ../packages/integrations/src/actions/integrations/teamsActions.test.ts`; `npm -w @alga-psa/integrations run typecheck`; `npm -w @alga-psa/ee-microsoft-teams run typecheck`; `npm -w @alga-psa/ee-microsoft-teams run build`.
