Summary

Stacked on #1406. An unclaimed developer's page now shows how many members are waiting to follow them, and members can join with a Follow button. When the developer signs up, everyone waiting follows them. That's the FOMO #648 was after: "14 members are waiting to follow you here".

Who's waiting:

• the members who followed the developer on GitHub when the page was looked up;
• the members who clicked Follow on the page. The button then reads Waiting, and clicking it again stops waiting.

Members also see the people they follow among those waiting. Guests only see the count, since who follows whom is for members.

Changes

• One table for every pending follow: pending_organization_follows (user_id, github_id, created_at), in production since 2026-11-01, is renamed pending_follows, keys included. It now holds the waits toward developers as well as organizations, by GitHub ID.
  • Why: it holds the waiting count and the follows to create when the account shows up.
  • Who sees it: everyone sees the count; members see the people they follow among the waiting; the user sees their own rows in their export.
  • When it's deleted: when the account shows up (the rows become follows), when the member stops waiting, or with the member, through the existing cascade.
  • Rows are keyed by GitHub ID, so a removed unclaimed profile keeps its waiting members for its next lookup.
  • During the deploy, code still running against the old table name fails briefly. The import job retries.
• At lookup time, for a new unclaimed profile: CreateGitHubProfile reads the developer's GitHub followers (up to 10 pages) before the profile exists, so a sign-in can't slip in between. It keeps only the members as pending follows.
• At sign-up: CreateFollowsFromPendingFollows turns pending follows into follows, each with the usual follow notification. It runs in UpdateOrCreateUser, only for a new user.
• Follow button: PendingFollowController store and destroy, which answer 404 unless the profile is unclaimed. The button is optimistic and rolls back on failure. Right after a click it doesn't turn into "Stop waiting" under the pointer.
• Deleting and exporting:
  • The member's rows go with them, through the existing cascade.
  • The export's pending_organization_follows becomes pending_follows: the GitHub IDs of every account the member waits for.
  • The knowledge base and privacy policy mention it.

Decisions

From the /interview, plus three follow-ups while building:

• Where do the waiting members come from? From the developer's GitHub followers, read when they're looked up, plus the Follow button. This replaces the plan to store every member's GitHub followings and backfill them:
  • nothing is stored about people nobody looked up;
  • no backfill;
  • it misses members beyond a very popular developer's first 1,000 followers.
• Notification at sign-up? The usual follow notifications. The inbox already groups a day's follows into one row ("@sam and 39 others followed you"), so no new notification type is needed.
• One table or two? One: the organization waits and the developer waits are the same thing, a follow waiting for an account to show up, so they share pending_follows and the export's pending_follows.
• Where does your own pending follow show? Only on their page. It isn't in your Following list or count.

Device verification

Phone layouts were checked with 390×844 viewport emulation in Playwright Chromium, not on a device. The member view on mobile wasn't captured, since only the button changes there.

Limitations

• Looking up a new developer now makes up to 10 more GitHub calls to read their followers, under the same rate-limit floor. If one fails, the lookup fails, and the member tries again from the page.
• The waiting count from GitHub is fixed when the developer is looked up. Members who follow them on GitHub later don't count, unless they click Follow.

Summary by CodeRabbit

• New Features
  • Members can wait to follow developers who haven’t joined yet, see how many people are waiting, and cancel their request.
  • Profile pages can show followed members who are also waiting.
  • GitHub follows can be imported as pending follows for developers who haven’t joined.
• Improvements
  • When a developer joins, waiting members automatically follow them and receive a notification.
  • Data exports include pending follows for developers and organizations, and pending follows are removed when the associated member account is deleted.

Walkthrough

The change adds pending follows for unclaimed developer profiles. Members can start or cancel a wait, and profile pages show waiting counts and selected waiting members. GitHub follower matches become pending follows and convert to follows with notifications when a developer signs up. Exports and account cleanup use the generalized pending-follows data.

Merge Risk: Low · up to d216e

Pending-follow cancellation has a narrow race, and canceled requests can leave stale button state; these should be addressed as follow-up fixes.

Security architecture risk: Moderate · up to d216e

A cancellation overlapping signup can succeed while the canceled wait still becomes a real follow. Because follows influence direct-message acceptance, this affects member consent rather than just the displayed waiting count. Authentication, ownership checks, and export filtering otherwise limit exposure.

Retained concerns

• Medium · security · inferred: Cancellation does not participate in the signup conversion transaction or a shared serialization protocol. Signup can select a member's pending row, cancellation can delete it and return success while the new account remains uncommitted, and signup can then attach and notify that member from its earlier selection. This also affects manual waits with no GitHub-follow relationship, so the new conversion path introduces exposure beyond the existing GitHub importer. The resulting follow can satisfy follow-based messaging acceptance despite the member's withdrawal.

Security review details

Security Blast Radius

• inferred — The identified race affects pending members for a developer signing up during cancellation. A developer controlling that GitHub account may benefit from an unintended service follow and its messaging-policy effects. Exploitation requires an existing wait and overlapping withdrawal; it does not provide arbitrary cross-user row creation, administrative access, or credentials.

Security Findings and Attack Paths

• inferred — A reachable ordering is: signup reads the pending member; a cancellation request still observes an unclaimed profile, deletes the pending row, and succeeds; signup attaches the member from its earlier collection and commits. The signup caller adds no outer lock that makes cancellation participate in the conversion protocol. This schedule has not been exercised in a concurrent runtime test.

Trust Boundaries and Controls

• observed — Pending-follow mutation routes require authentication and use follow throttling. Requests authorize only unclaimed developer profiles, controllers supply the current user, and cancellation filters by that user's ID. Export remains authenticated and bound to the current user, with pending rows filtered by the same owner ID.

Resilience and Maintainability Implications

• observed — The pre-existing post-signup GitHub importer is another follow writer: on its initial people import it fetches current GitHub followers and attaches matching members independently of pending rows. Deleting a pending row is therefore not a durable exclusion from that importer. This import behavior and its exposure already existed at the base and are not counted as a separate PR-introduced security finding.

Hardening Proposals

• proposed — Define one authoritative ordering for cancellation and conversion so a successful withdrawal cannot later commit as a follow. If conversion wins that ordering, return or reconcile the claimed-account state rather than reporting a completed cancellation. Separately define whether withdrawal must survive GitHub re-import; if so, represent that decision explicitly rather than relying on absence of a pending row.

Serialize cancellation with profile claim.

If a member stops waiting while the developer signs in, conversion can read the pending row before this deletion commits. Conversion can then attach the follow and notify the developer after the member’s cancellation succeeds. Lock the same profile during deletion. If conversion wins the lock, handle the newly created follow instead of deleting zero pending rows. PostgreSQL row locks do not block the conversion’s current plain read. (raw.githubusercontent.com)

Review comment at @app/Actions/DeletePendingFollow.php at line 18:
Update DeletePendingFollow to serialize cancellation with profile conversion by
acquiring the same profile lock before deleting the pending follow; ensure
conversion also uses a lock that blocks this claim, since its current plain read
is insufficient on PostgreSQL. If conversion acquires the lock first and creates
the follow, make cancellation handle that follow rather than treating a zero-row
pending deletion as success.

Not changing this. The window needs the member to stop waiting in the same few milliseconds as the developer's sign-up, and the worst outcome is that the member follows someone they meant to stop waiting for, which one click undoes. Closing it fully would also mean deleting the follow the conversion just made, a lot of code for that case. CreatePendingFollow locks because the opposite race left a row that was never converted.

[coderabbitai]

@mnapoli Understood. You accept the cancellation race because the member can undo the resulting follow. The CreatePendingFollow lock prevents a different outcome: a pending row that never converts. I won’t press for this change.

Roll back the optimistic state when the visit is canceled.

WaitButton updates the state and count before router.visit(...). A canceled visit does not use the HTTP or network-error rollback, so the button can remain Waiting with an incorrect count. Add the cancellation rollback used by the existing follow implementation.
