Greptile SummaryThe PR adds typed reconnect errors, persisted tenant-scoped connect requests, token-freshness handling, and a React connection flow. The popup-close flow can currently report cancellation when a successful final status request completes after its fixed grace period.
Confidence Score: 4/5The PR needs the popup-close race fixed before merging because a completed connection can be returned to the caller as a cancellation. A final status request may begin before popup-close detection but resolve after the 1500 ms grace; the grace invalidates its attempt first, causing the confirmed connection to be discarded and preventing the caller's action from resuming.

Ignore status polls from a closed or superseded connection attempt via an attempt-id guard, so a late poll can no longer settle the wrong promise. Drop the postMessage fast-path. The connect success page cannot pin a target origin to an arbitrary customer app, and the status poll plus popup-close watch already detect completion everywhere, including self-hosted and custom connect pages.
When a tool call raises auth-missing, the binding writes a per-tenant row to corsair_connect_requests with the plugin and its connect link; the management handler exposes it (GET /connect/request, POST /connect/request/clear), tenant-scoped so end-user mode can't read across tenants. Registered in REQUIRED_TABLES so a missing table warns to run migrations instead of 500ing.
Wrap the app once in <CorsairProvider>: an auth-missing failure surfaces a connect dialog and resumes the failed work once connected, with no per-call code at the call sites. <CorsairBoundary> covers server-rendered reads; useConnect exposes the proactive connect() and the call() mutation wrapper. Splits a browser bundle so the dialog renders inside any host app.
Document the connect-request table across the SQLite, Postgres, Drizzle, and Prisma migrations and the core-tables reference.

The status poll and connect-request clear now use the tenant the link was minted for, so a proactive connect for a non-default tenant no longer watches the default one. A settled attempt bumps its id before running effects, so a slower poll from the same attempt can't refresh the router twice, and unmount tears down the popup, timers, and any waiting promise. PluginIcon resets its source when the domain changes so a reused mark never shows the prior brand.
…tore responses recordConnectRequestBestEffort now keys on the error's own tenantId — the tenant the scoped connectUrl belongs to — and falls back to the binding's tenant, so the owner can read its own pending request instead of it landing under `default`. The connect-request GET is served Cache-Control: no-store so a shared cache can't hand one tenant's connect link to another browser.
rm -rf isn't available under cmd.exe, so the pre-tsup clean broke Windows builds. Use node's fs.rmSync, which runs on every platform.

window.open returns null when the browser blocks the popup; the watcher then never settles because there is no window to observe, so connect() hung. Guard it — end the attempt so the promise resolves and the caller can retry. Also correct the call() contract docs: it retries whenever a connect-request is pending (the server records that across the RSC boundary where the typed error is lost), so it is documented for connect-gated or retry-safe mutations.

When the popup closes after a successful connection but the final status request takes longer than the 1500 ms grace, this callback invalidates the attempt and settles it as cancelled. The eventual connected response is then rejected by the attempt guard, so connect() resolves false or call() returns null even though the account connected.

Fixed in 719c807 — when the grace fires it now runs one authoritative status check and settles on the result, so a slow final poll after popup-close confirms success instead of discarding it as a cancel.
…cancel The success page closes the popup only after the connection persists, but the confirming status poll can outrun the grace window. The grace timeout used to settle cancelled outright, so a slow final poll discarded a real success — connect() resolved false though the account connected. It now runs one authoritative status check when the grace fires and settles on the result. Extracted finishConnected/finishCancelled to share that path with the poll.
Publishes Corsair Connect (provider, boundary, dialog) and the reconnect error.
Add a Corsair Connect section to the React adapter page (CorsairProvider, CorsairBoundary, useConnect, and the React-only caveat), and note the typed AuthMissingError / ReconnectRequiredError under error handling. Rebuild both llms.txt files against the current docs: the index had drifted — the Frameworks, Use cases, Workflows, Management, and LLM-gateway sections were missing and one MCP path (openai-agents) no longer exists. Regenerated from the live nav and page frontmatter, with every link verified to resolve.
