What shipped in the second half of August

Self-serve sign-up and payments now work end to end, in pre-production, with invites gating who gets in. We spent the rest of the window on the parts that get people through that door reliably: the GitHub connect step, saved documents, and orgs that get stuck partway through setup.

• Self-serve sign-up and payments now work end to end, in pre-production, gated by invites.
• The GitHub connect step is more reliable now, with a longer-lived cookie and a permission list that matches what GitHub actually asks for.
• A directory with more than 50 files no longer gets cut off; the doc tree keeps loading as you scroll.
• We fixed a bug that could silently drop a write with no warning.
• Title generation now retries instead of failing silently.
• Orgs that never finished setting up can now be deleted.
• Org data now stays scoped to the org it belongs to.
• We fixed a race where a billing refresh could overwrite details from a sign-up in progress.
• We fixed a bug that could take search down for an account, and repaired the accounts it had already hit.
• We retired the old promo site.
