1. Database migration

• 1.1 Update Drizzle schema in packages/db/src/schema/journal.ts: rename syncConnections table to connectedServices, add credentialKind (text, NOT NULL) and credentials (jsonb, NOT NULL) and status (text, NOT NULL DEFAULT 'active' with CHECK constraint for active | needs_relink | revoked); drop accessToken, refreshToken, expiresAt.
• 1.2 Generate migration via pnpm db:generate; hand-edit if needed so backfill runs in the same transaction as the column adds (UPDATE connected_services SET credential_kind = 'oauth', credentials = jsonb_build_object('access_token', access_token, 'refresh_token', refresh_token, 'expires_at', expires_at)), then drop the old columns.
• 1.3 Verify the migration on a local database with seeded Wahoo connection rows; verify the inverse rollback restores the columns from JSONB.
• 1.4 Update FK references in sync_imports and sync_pushes if any reference the table name (likely none — both reference users / routes, not connections).

2. ConnectedServiceManager + OAuth CredentialAdapter

• 2.1 Create apps/journal/app/lib/connected-services/types.ts with ConnectedService record type, CredentialKind, Credentials (discriminated union per kind), NeedsRelink error class, Status enum.
• 2.2 Create apps/journal/app/lib/connected-services/credential-adapters/oauth.ts implementing CredentialAdapter with refresh(creds, providerConfig) → Credentials | NeedsRelink and optional revoke.
• 2.3 Create apps/journal/app/lib/connected-services/manager.ts exposing link / unlink / withFreshCredentials / markNeedsRelink. Persistence via Drizzle on the connectedServices table.
• 2.4 Write manager.test.ts: in-memory tests with stub CredentialAdapter covering refresh-on-expired, refresh-fails-→-needs_relink, link/unlink, markNeedsRelink, status short-circuit.
• 2.5 Write credential-adapters/oauth.test.ts: contract tests against a mocked token endpoint (refresh success, refresh 4xx → NeedsRelink).

3. Provider manifest + registry

• 3.1 Create apps/journal/app/lib/connected-services/registry.ts and types.ts capability interfaces (Importer, RoutePusher, WebhookReceiver, ProviderManifest).
• 3.2 Create apps/journal/app/lib/connected-services/providers/wahoo/manifest.ts declaring credentialKind: 'oauth', OAuth config (auth URL, token URL, scopes), and references to capability adapters.
• 3.3 Wire providers/registry.ts to import the Wahoo manifest. Expose getManifest(providerId) and getAllManifests().

4. Wahoo capability adapters

• 4.1 Move and reshape Wahoo importer logic into providers/wahoo/importer.ts implementing the Importer seam (listImportable, importOne). Internally calls withFreshCredentials for any auth'd Wahoo HTTP. Keep FIT→GPX conversion isolated.
• 4.2 Move and reshape Wahoo route push logic into providers/wahoo/pusher.ts implementing RoutePusher (pushRoute(service, route) → {remoteId, version}). Keep FIT-Course conversion, external_id = route:<id>, the PUT-vs-POST decision, and the PUT→POST-on-404 fallback inside the adapter. Read/write sync_pushes per the existing idempotency rules.
• 4.3 Move and reshape Wahoo webhook handling into providers/wahoo/webhook.ts implementing WebhookReceiver (parseWebhook, handle).
• 4.4 Reorganize tests: split existing wahoo.test.ts (285 lines) and pushes.server.test.ts (309 lines) into providers/wahoo/{importer.test.ts, pusher.test.ts, webhook.test.ts} against a fake ConnectedServiceManager that yields stub credentials. Use git mv first, then split, so blame survives.

5. Caller migration

• 5.1 Update OAuth connect routes (/api/sync/connect/wahoo, callback) to call ConnectedServiceManager.link with credentialKind: 'oauth' and the JSONB credentials shape. Remove direct writes to the old token columns.
• 5.2 Update disconnect route (/api/sync/disconnect/wahoo) to call ConnectedServiceManager.unlink.
• 5.3 Update webhook route (/api/sync/webhook/wahoo) to look up the manifest via the registry and dispatch to its WebhookReceiver. Unknown provider_user_id still returns 200.
• 5.4 Update the route push action and any background jobs (apps/journal/app/jobs/) that previously called into apps/journal/app/lib/sync/. Replace direct connections.server.ts reads with withFreshCredentials.
• 5.5 Update the connections settings page (/settings/connections) and any UI surfaces reading granted_scopes to read from the connected_services row directly.
• 5.6 Delete the old apps/journal/app/lib/sync/ directory once all imports are gone. Delete the old SyncProvider interface from types.ts.

6. Verification

• 6.1 Run pnpm typecheck && pnpm lint && pnpm test — all green.
• 6.2 Run pnpm test:e2e with the Wahoo flow specs — all green.
• 6.3 Manual smoke test: connect Wahoo locally, import a workout (manual + webhook simulated), push a route (POST then PUT), disconnect, reconnect — all working.
• 6.4 Check that connected_services migration applies cleanly to a copy of staging data (or local seed reflecting prod).

7. Documentation + follow-up

• 7.1 Update CONTEXT.md if any term was sharpened during implementation.
• 7.2 File a follow-up issue/note to amend openspec/changes/komoot-import/design.md to use connected_services + web-login credential kind instead of the drafted journal.integrations table.
• 7.3 At archive time, apply the spec deltas in specs/connected-services/, specs/wahoo-import/, specs/wahoo-route-push/ to openspec/specs/.
