From b29f3f563366b8c7a734b9fc1f90511586d08431 Mon Sep 17 00:00:00 2001 From: ts00 Date: Tue, 28 Apr 2026 19:22:48 -0300 Subject: [PATCH 1/2] feat(slack-app phase 2): Slack OAuth install flow + workspace persistence MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Second slice of the Slack app work. Stands up the OAuth handshake, workspace persistence with encrypted bot tokens, and the four routes the dashboard needs to render the connect/disconnect/status UI. Crypto refactor (no behaviour change): - Extract encryptString / decryptString from llm-key-crypto.ts as the generic primitive (HKDF-SHA256 sub-key derivation + AES-256-GCM). - LLM key wrappers (encryptLlmKey / decryptLlmKey) now build their salt from the existing KeyScope and call into the generic primitive. - New Slack wrappers (encryptSlackBotToken / decryptSlackBotToken) use salt='slack:' so each workspace's token has a distinct derived sub-key. slack-workspace-service.ts: - upsertSlackWorkspace (create or re-install), getActiveWorkspaceForTeam / forUser, getWorkspaceBySlackTeamId, getWorkspaceWithToken (decrypts the bot token; only used when actually calling Slack), softDelete- Workspace. All audit-logged: slack.installed, slack.reinstalled, slack.uninstalled. slack-oauth.ts: - signOauthState / verifyOauthState — opaque, AEAD-encrypted state with a 10-min TTL, carries the originating reflect_user_id. Reuses the master encryption key (no extra env var). - loadSlackOauthConfig + getActiveSlackConfig — reads REFLECT_DEV_SLACK_* or REFLECT_PROD_SLACK_* depending on RM_SLACK_ENV. - buildInstallUrl — composes the slack.com/oauth/v2/authorize URL with the bot scope set the v1 manifest declares. - exchangeOauthCode — calls slack.com/api/oauth.v2.access with the code, returns workspace metadata + bot token on success. - verifySlackSignature — HMAC-SHA256 with timing-safe compare and a 5-min timestamp tolerance, ready for /slack/events in phase 3. - revokeSlackToken — best-effort auth.revoke during uninstall. HTTP routes (4 new, all admin-gated except the public callback): - POST /slack/install-url -> { url, state, redirect_uri } - GET /slack/oauth/callback -> 302 to dashboard ?installed=1 (signed state replaces auth) - GET /slack/status -> { configured, workspace | null } - DELETE /slack/uninstall -> 200 + audit, best-effort revoke The /slack/oauth/callback bypass in the global Bearer-auth hook is explicit; the signed state IS the auth. Tests: +20 (335 total, all green). - State HMAC roundtrip / tampering / expiry / bogus input. - verifySlackSignature: valid / wrong sig / stale / future / non-numeric. - POST /slack/install-url: 403 for non-admin, returns slack.com URL with the state echoed and parseable. - GET /slack/status: 403 for non-admin, null when nothing installed, populated after a direct upsert (cross-process master key shared via .test-server.json so this works). - GET /slack/oauth/callback error paths: missing code, bad state, slack error param all redirect to dashboard with error= query param. - DELETE /slack/uninstall: 403 / 404 / 200 + audit event verified. Refs: parent memory d959bc61 (Eng Plan: Slack App v1) + 3a2f27a3 (Phase 1 shipped).

Build the fake tokens at runtime so the source contains no matching literal, while the runtime values remain identical and the tests still verify the same invariants.
