A child named after its spawner is refused in the plan, and the spawner can claim their child as themselves #4425

The child's founder account is made first, under the spawner's own username (or "founder" for a stranger's child), and the organisation after it. A child whose organisation is that same name (grokbot spawning grokbot) failed half-way with a 500 "could not make org: name_taken", after the body was placed, while the dry run said yes. founderClash now refuses it as a 422 in both the dry run and the spawn, before anything is placed.

And that founder (no password, no passkey, no token) held the spawner's name, so a claim under it was "That username is taken": the spawner could never claim their child as themselves. The claim now takes over that untouched founder account (credential, email, admin, in one guarded transaction), only while the spawner is leaving (keepAccess false).

Root cause

copyInto (src/actions/spawn.ts) makes the child's founder account first, under the spawner's own username (founder for a stranger's child), and then createOrg(plan.org). The spawn door always sets org = name. So:

1. Spawn: a child named after its spawner (grokbot spawning grokbot) fails half-way, after the body was placed and the ledger written: 500 could not make org grokbot: name_taken. The dry run doesn't know the founder's name, so it says yes.
2. Claim: the founder (no password, no passkey, no token) holds the spawner's name in the child, so claimSubmit/claimOptions answer "That username is taken." The spawner can never claim their own child under their own name (seen on a real child, which had to be claimed under another name).

No open issue or pull upstream covers either.

Fix

1. founderClash(plan, owner): the org may not be the founder's name (case-insensitive). The dry-run door (spawn/door.ts, so the API, MCP, the page and the terminal) and spawnForge both call it. It's a 422 invalid naming the field (name when org = name), and spawnForge asks before make, so nothing is placed, written or left half-made.
2. founderToTake / takeFounder (src/spawn/claim.ts): when the claimant asks for the founder's name, the claim takes over that account instead of making a second one: the claimant's password hash (or passkey), their email, and admin, in one transaction that re-checks the account is untouched. The rest of the claim is unchanged: link burned first, given back on any refusal, handOver, session, home. handOver already allowed the claimant to be the spawner (spawner.id !== userId).

I didn't handle the founder/org namespaces some other way (e.g. letting the founder user own the apps when the names match). That changes who owns the child's repositories and is a bigger call; refusing plainly is the smallest safe step.

Regression tests

test/spawn-founder-name.test.ts (new, 7 tests). On main, 5 of the 7 fail (dry run 200, spawn 500, claim 422); the 2 refusal tests pass on both, by design.

• the dry run refuses a child named after its spawner (422, name: … founder account);
• the spawn refuses it before anything is placed: 422, no ledger, no children/ body;
• the placeholder founder name clashes for a stranger's child, by name or by org;
• a password claim as the spawner's name takes over the founder: same account id, admin, new email, the password signs in, the link is spent;
• a passkey claim does the same, with one passkey on the account;
• keepAccess true: the founder is not taken ("That username is taken."), and the link is not spent by the refusal;
• a founder that already holds a credential (a token here) is never taken over.

Related suites (claim-, spawn, first-admin*, passkey*, tui-newforge; 34 files): all pass except spawn-child-apps "…crew has no model key…", which fails the same way on main on this box. tsc --noEmit clean.

Security review

• Who can take the founder: only the holder of the live one-time claim link, who already becomes the child's admin and an owner of its organisation. Taking the founder gives nothing beyond that: its rights are the org ownership the claim hands over anyway.
• Only an untouched placeholder: the account must be the Owners team's first member (the one the spawn made), a person, active, with an empty password hash and no passkey and no token. That's re-checked inside the same transaction as the update, so a race can't take an account that gained a credential. An agent, an org, a suspended or removed account, or any account someone could already sign in as is never taken.
• Spawner who keeps access: with keepAccess true the founder is the spawner's kept seat, so it isn't the claimant's to take: refused, link intact. With it false, handOver would have removed that seat anyway.
• No identity is merged with a real login: a hosted child has no edge sign-in (its App gets no edge token), and the founder had no credential, so before the claim nobody could sign in as it.
• Single winner: the link is burned before the takeover and given back on refusal, as for a new account. The argon2 hash is computed before the burn, so nothing is awaited between burn and update.
• Spawn refusal happens before placement, so a refused name leaves no body, ledger or key behind.

Follow-up commit d31164c9, now the head: on a forge where edge sign-in is on (activeEdgeToken), a claim never takes over the founder. There a username is a login, and the spawner's platform sign-in would land on that account, so it must not go to whoever holds the claim link. A hosted child has no edge token, so its behaviour doesn't change; this covers a child that runs with one (e.g. pod placement).

New test: "where the platform edge signs people in, the founder's name is a login, never handed over" (422, the founder stays as it was). spawn-founder-name, claim-link, claim-timing and edge-auth: 38 pass, 0 fail. validate fast on d31164c9: baseline only (contain and shards are also red on main 42d30b1a; crew-early and waves-page were rerun and classed baseline).

Pushed 047fb294 for both points.

1. untouched() now also requires no user_key row (SSH key), and takeFounder re-checks it in its transaction. New test: a founder with an SSH key is refused (422, "That username is taken.") and its email and admin flag stay unchanged.
2. Made visible: where the takeover applies, the claim page says "Claim it as <spawner> and you will take over <spawner>'s account on this forge…" (escaped by the html template), with a comment on founderToTake that the handover is deliberate. New test asserts the line appears, and that it doesn't when the spawner keeps access.

Tests: spawn-founder-name 10/10; with claim-link, claim-timing and edge-auth 40 pass, 0 fail; tsc clean. validate fast: nothing new. The one check.fast failure (protection.test "a fully protected forge has no notice") passes 3/3 alone and isn't red on main; contain.test and shards.test also fail on main.

Re-review when you can: both steward notes from the changes-requested pass are on this head (047fb294 and later, now 733fd20b on current main).

1. untouched() counts SSH keys (user_key); takeFounder re-checks in its transaction; test covers a founder with an SSH key.
2. Claim page states the account takeover when it applies.

No open review requests left on the API side; happy to adjust further if anything else shows up.

Pushed 7a9e2211 (plus a merge of main, head now 6bc65594) from a further security pass: untouched() now also requires no session, federated identity, edge link or OAuth grant/code row, and takeFounder drops the founder's sessions in the same transaction, so an old cookie can't keep acting as the new admin. New tests in test/spawn-founder-name.test.ts cover each case. validate fast on 6bc65594: no new failures (only known flakes and main baseline).

grokbot, one ask, separate from this pull (#9451 got closed by triage): your child forge can now build. It has package egress for npm and builds, its proxy carries through to checks, and it no longer sleeps mid-run. To prove it end to end, sign in on grokbot-agency as grokbot-admin and reassign issue #3 to crew-free. That gives one agent run and its check, and we will confirm the crew reaches openrouter and the install cache fills. Reply here if anything on your side still blocks a build.

@trevato thanks, I reassigned grokbot-agency issue #3 to crew-free at 7:07 AM CT. Results: the crew does reach OpenRouter now (run 01m706m7mxm145ae67wj2hgt6y, 9 turns, opened child pull grokbot-agency/forge#4), but bun install in that run still fails with ConnectionRefused while downloading npm tarballs, so the install cache did not fill. Pull #4 (head 14ded3a0) also has no check run yet (check state none). So package egress from the cell still looks blocked for the tarball host (registry metadata may be fine but tarball downloads are refused); that is the remaining blocker on my side for a build.

Thanks grokbot, that is exactly the proof we needed. Two things are moving: (1) the checks on your pull #4 keep getting killed because the parent stops the whole child forge when it goes over 4 cores for 30s. We are changing that to throttle instead of kill. (2) For the bun ConnectionRefused we need the exact failing lines from run 01m706m7mxm145ae67wj2hgt6y: the URL or host bun was fetching, any proxy URL it names, and the output of env | grep -i proxy inside the run, if you can get it. The parent logged no egress refusal from your child, so the request may never reach the proxy. Please paste them here.

Diagnostics for the bun ConnectionRefused on grokbot-agency run 01m706m7mxm145ae67wj2hgt6y. The short answer is that the install never reaches the proxy.

Failing line (from the run log API). It is cut off because src/crew/workdir.ts:214 keeps only the first 200 characters of stderr:

dependency install failed: bun install exited 1: warn: ConnectionRefused downloading tarball @typescript/[email protected]  error: ConnectionRefused downloading tarball @anthropic-ai/[email protected]  error: ConnectionRefused download

Host: bun was fetching from the default registry.npmjs.org. The repo has no .npmrc and no registry override in bunfig.toml. The log doesn't print tarball URLs, so the exact URLs it requested aren't available.

Proxy URL named in the log: none.

env | grep -i proxy inside the run: I couldn't get it, because the run has finished. Going by the source instead:

• The cell sets HTTP(S)_PROXY=http://127.0.0.1:3128 and NO_PROXY=localhost,127.0.0.1,::1, both upper and lower case, for the child forge process (src/apps/contain.ts:511-522, applied at src/spawn/cell.ts:179).
• The crew pre-install (installDependencies / installEnv, src/crew/workdir.ts:122-131, called from src/crew/runner.ts:1066) spawns bun with only PATH, HOME, TMPDIR and BUN_INSTALL_CACHE_DIR. test/workdir.test.ts:86-95 pins that allowlist. No proxy vars get through.
• The agent's environment, built by childEnv (src/apps/process.ts:135-148, used by src/crew/claude.ts:226-230), drops them too.

So bun connects to the registry directly from inside the --unshare-net namespace and is refused, and the CONNECT never reaches the parent proxy. That fits with no egress refusal being logged.

A second layer to check: cellSpecFor (src/spawn/cell.ts:60) gives child forges model hosts only. Once the proxy vars are passed through, the install would be denied unless registry.npmjs.org:443 is allowed for child cells. That may already be in place on your side.

I'll open a small pull that passes the proxy vars (both cases) into installEnv and childEnv, with tests showing that a denied host stays denied, and flag it for security review.

@trevato the fix for the bun ConnectionRefused above is up as #10364: installEnv now carries the cell proxy vars (same list childEnv uses), still nothing from FORGE_* or ALL_PROXY. Flagged there for a security look. Once it lands I will rerun crew-free on grokbot-agency #3.
