getWebhookEndpointUrl now returns { url, clientState }; msGraphSubscribe uses
that shared clientState instead of a random per-subscription one, so every
tenant's Graph subscription carries the value Hub's verifyMsGraph checks — fixing
multi-tenant 'bad signature'. Falls back to a random clientState only when Hub
doesn't supply one (pre-fix Hub).

This plugin PR changes shared Corsair files outside packages/teams and the permitted exceptions. The repository requires plugin PRs to remain inside one packages/<plugin>/ directory. The same violation occurs in packages/corsair/core/webhooks/ms-graph-subscribe.ts, packages/corsair/hub/webhook-endpoint-client.ts, and other changed packages/corsair files.

channelSubscription is captured from the shared Teams plugin options and passed to every tenant's subscription. In a multi-tenant instance, all accounts therefore try to subscribe with the same tenant-specific Graph team and channel IDs. Tenants that do not own those resources receive an authorization or not-found failure, so their channel webhooks are not armed.

The new outer if (accessToken) also guards the local deletion branch. If a deletion notification arrives after the account token is missing or revoked, deleteByEntityId is never called even though it requires no Graph request. The deleted channel message consequently remains in local storage; the sibling Teams handlers correctly require a token only for hydration.

Reject malformed clientState values.
If Hub returns a non-string clientState, getWebhookEndpointUrl forwards it. msGraphSubscribe preserves any truthy value, sends it to Graph, and stores it through the string-typed set_webhook_signature contract. Validate clientState before returning it and add a malformed-payload test.

Process deletion notifications without an access token.
If get_access_token() returns no token while ctx.db.messages is configured, the current guard skips the loop. A deleted notification cannot call deleteByEntityId, so the persisted message can remain stale. Process deletions independently of hydration, and add a no-token deletion regression test.
Proposed fix

try {
for (const { resourceData, resource, changeType } of notifications) {

What
Makes Microsoft Graph (Teams) channel-message webhooks work in multi-tenant apps, end to end. Pairs with the Hub change corsairdev/hub#101 (merged + deployed): Hub now serves one shared endpoint
clientStatefor MS Graph plugins, and the SDK threads it onto every subscription soverifyMsGraphaccepts notifications from every tenant.Proven end to end on a live Slack↔Teams bridge: Teams→Slack and Slack→Teams, root + reply + thread, echo-suppressed, over a real tenant.
Why
Two independent bugs blocked multi-tenant Teams webhooks:
Random per-subscription clientState (core). Each tenant's subscribe minted its own random
clientState, but Hub verifies every inbound notification against a single shared endpoint secret — last-writer-wins meant all but one tenant failedbad signature. Fix: the SDK reads Hub's sharedclientState(H1 endpoint) and stamps it on every Graph subscription; falls back to a random one only when Hub doesn't supply it (pre-fix Hub / non-managed).Double verification (teams). After Hub verifies a delivery it sets
request.hubVerifiedand, by contract, withholdsctx.key— but the teams handlers unconditionally re-verifiedclientState, 401-ing every Hub-delivered notification with "clientState is required". Fix:verifyTeamsWebhookskips the app-side check whenhubVerified, keeping it for the direct (no-Hub) path.Also hardens subscription renewal: it enumerates every credentialed account, so it routinely meets not-connected ones (tenant connected another plugin, or revoked) — those now skip quietly instead of warn-spamming an
AuthMissingErrorstack trace every pass.Changes
