Make my forge ends signed in on the new forge: no code to copy #8040

A stranger who makes a forge from /forges/new now gets a 303 to /forges/<name>/waiting#<token> in the same answer that shows the claim link. The waiting page sends them on to the child's claim form once the child is up. The new test passes; the ~46 related spawn and claim test files pass too. The suite is not run in full here.

• Redirect: in newForgeSubmit (src/web/pages/new-forge.ts), only a stranger (no signed-in user) gets the 303. The response keeps cache-control: no-store and its body still shows the link once. The token is in the fragment only.
• Waiting page: GET /forges/:name/waiting is static and never holds the code. A few lines of script read the code from location.hash, clear it from the address bar, and poll /forges/:name/ready. When that says ready, the browser goes to the child's /claim#<token>. The code arrives already filled in from the claim form (#2924), which I did not touch. Without JavaScript, the page tells them to open the claim link they were given.
• Readiness check: GET /forges/:name/ready has the parent ask the child's /healthz, so the browser never reaches a child that is still booting. It uses the existing probe, which tests can replace. It rejects names that are not valid child names with 404, and rate-limits strangers per request.
• Supporting changes: src/spawn/door.ts gains a small childLive helper. NAME in src/spawn/plan.ts is now exported for the name check. The two routes are registered in src/http/server.ts.
• Test: test/claim-redirects.test.ts follows the flow from the form to the 303, the waiting page and the ready check, then claims on a real child app. It asserts that:

- the fragment is the only place the code appears; - nothing under the spawn directory contains the code; - the waiting page carries no secret; - the first admin is signed in and sees their username.

The issue says the child's /health. I used /healthz, the probe the repo already has. I also did not add a visible "waiting" state beyond the one status line.

Checks: gate.ts, tsc --noEmit and design-lint printed no errors. bun scripts/fast.ts said the diff was too broad to name tests, so I ran the new test and the spawn, claim and new-forge files instead. Network calls to *--forge.test hosts were denied by the sandbox during the run, with no test failing.

To try it, submit /forges/new as a signed-out visitor. You land on the waiting page, and when the child answers you are on its claim form with the code filled in.

A stranger who makes a forge now lands on a waiting page, and from there reaches the new forge's claim form with the code in the URL fragment only. I fixed one of the two failing checks and could not reproduce the other, which isn't in this repository.

What changed

• POST /forges/new from a stranger answers 303 to /forges/<name>/waiting#<code>, with cache-control: no-store. The body still shows the claim link once.
• The waiting page holds no secret. It asks /forges/<name>/ready whether the child is up, then sends the visitor to the child's /claim, with the code read from location.hash.
• A name that isn't a valid child name gets 404 from both routes.
• The new pieces are src/web/pages/forge-waiting.ts and childLive in src/spawn/door.ts. NAME in src/spawn/plan.ts is now exported so the routes can validate with it.

The two failures

• "from the form to a signed-in admin on the child…" (test/claim-redirects.test.ts): it passed alone for me and I never saw the shard failure, so the cause below is my best reading. The test let the spawn boot a hosted child in the background, while the test opened its own app on the same data directory. I think those raced under the shard's load. The test now places the child with a stub, as test/spawn-anon.test.ts does, so nothing boots behind it. It passes on three repeat runs here. No source changed.
• "the proxy adds under 5 ms (median) and 20 ms (p95) with the toolbar rewrite": this test isn't in this repository; I searched test/ and src/ for its name and wording and found nothing. It is a timing assertion, and I read it as load noise in a 59-shard run. I didn't touch it. If it fails again on this push, a person should look at it.

Not run

• bun x tsc --noEmit and bun scripts/gate.ts printed nothing, so I take them as clean, but I didn't confirm an exit code.
• I ran only test/claim-redirects.test.ts. I left the full suite to the forge's check on this push.

To try it: open /forges/new signed out, make a forge, and follow the waiting page. test/claim-redirects.test.ts covers the whole path from the form to a signed-in admin on the child.

Parked by the crew: the check stayed red through 2 automatic tries

A new forge's creator now lands on the waiting page, which sends them to the child's claim form with the code already in the fragment. The red check came from a stale test, and I fixed that.

What was red: after I merged main, test/claim-redirects.test.ts looked for location.hash in the waiting page's HTML. On main, page scripts are served as hashed /assets/page-*.js files instead of inline, so the assertion failed. The page code (src/web/pages/forge-waiting.ts) was fine. The test was wrong, not the code, so I changed only the test. It now reads the script the page names, using the existing test/helpers/page-script.ts.

What I ran:

• bun scripts/gate.ts and bun x tsc --noEmit: clean.
• bun scripts/design-lint.ts: clean.
• test/claim-redirects.test.ts passes (2 tests), and so do test/web-budget.test.ts and the new-forge tests.
• I did not run bun scripts/fast.ts and the tests it names. The command timed out at 120 seconds in the sandbox and I didn't retry it, so the forge's full check on this push is the first full run.

What's on the branch: the earlier commits are unchanged. The short door answers 303 to /forges/<name>/waiting#<code>. That page holds no secret and polls /forges/<name>/ready until the child answers. It then goes to https://<child>/claim#<code>. The link is shown once, in that first answer, and the test checks that nothing under the spawn directory holds it.

To try it, open /forges/new, make a forge, and watch the redirects. The test follows them from the form to a signed-in first admin on the child.

The two failing tests are green locally and the fix is pushed. I haven't seen the forge's re-run of the check yet. The pull itself changes nothing in the terminal; both failures came from other changes landing on main while it was open.

• Private destinations in the terminal (test/tui-egress.test.ts): main had since fixed this one. Merging origin/main into the branch cleared it, and I changed nothing for it.
• Upstream in the terminal (test/tui-upstream.test.ts): the new b default branch hint (#8302) lengthened the About card's footer. The test's 120-column terminal truncated the line before it reached "check upstream now". I widened that test's headless terminal from 120 to 220 columns. The test was wrong, not the code.

I did not touch src/tui/screens/about.ts, so the footer still truncates at 120 columns. That limit is why the hints can fall off the end, and a separate change could address it if you want it fixed.

Locally, both TUI test files pass (8 tests), as does test/claim-redirects.test.ts after the merge, and bun x tsc --noEmit is clean. I did not run scripts/gate.ts.

I merged main into the branch and pushed it. The merge had one conflict, in test/tui-upstream.test.ts.

main had fixed the same footer-truncation problem I fixed earlier by widening the test terminal. I widened it to 220 columns and main widened it to 300, so I kept main's version and my 220-column change is gone.

Locally, test/tui-upstream.test.ts and test/claim-redirects.test.ts pass (5 tests) and bun x tsc --noEmit is clean. I did not run scripts/gate.ts or the rest of the suite. The forge's check runs on the push.

The pull has one "changes requested" review, but I couldn't find its text, so I changed nothing and pushed nothing. The reviews, threads and comments endpoints return no review text. The only other comment is the crew's "parked" note on the red check, which has since been fixed. I won't guess at what to change.

The branch is unchanged and the forge's check on head 9171d243 passed in 510s.

A stranger who makes a forge from /forges/new gets a 303 to /forges/<name>/waiting#<code>. That page holds no secret. It polls /forges/<name>/ready, which has the parent ask the child's /healthz. When the child answers, it sends the visitor to https://<child>/claim#<code>, and the code stays in the URL fragment the whole way. Nothing under the spawn directory holds the code. A name that isn't a valid child name gets 404 from both routes.

The issue says /health, but I used the existing /healthz probe.

To try it, open /forges/new signed out and make a forge. test/claim-redirects.test.ts follows the whole path from the form to a signed-in first admin on the child.

What I need: the reviewer's feedback, either as a pull comment or as a pointer to where it is. I'll address it as soon as I can read it.

Handed to a person by the crew: two follow-up runs on the review's changes ended without a push, so no more start here until you say what to try. (The forge posts this under the reviewer's name; the reviewer did not write it.)

Merged main into the branch and pushed; the forge's check will now run on it.

Conflict: the only one was in src/spawn/plan.ts. My side exported NAME. main added a PLAN_KEY constant next to it. I kept both, with NAME still exported.

Tests: the ten spawn and new-forge test files I ran pass (76 tests). I did not run the full suite. scripts/fast.ts could not name a smaller set, because the diff reaches 1891 of 2706 files.

tsc: it fails here, but only on @vscode/ripgrep missing from three test files. That comes from the sandbox's missing module, not from this merge.

Gate: scripts/gate.ts and the pre-push hook wanted Try:, No door: and Direction: lines in a commit message. I added them in an empty commit. The No door line says the terminal already prints the claim link; I took that from the existing spawn flow and did not re-check it.

Try it: open /new on the preview as a stranger, make a forge, and the waiting page should send you to the child's claim form.

The waiting page no longer re-arms a fetch with setTimeout, so the two failing no-polling tests should now pass. They passed locally along with the claim-redirects tests, and the type check and scripts/gate.ts were clean. The forge's full check hasn't run on the new push yet.

What changed

• Cause: src/web/pages/forge-waiting.ts polled /forges/:name/ready on a 1–2 s setTimeout. The no-polling test flags that as an interval by another name.
• Fix: /forges/:name/ready?wait=1 now holds the request open for up to about 15 s while the parent probes the child's /healthz once a second. The page asks again as soon as an answer comes back, so it has no timer. It stops after 60 asks and tells the person to reload. A failed fetch counts as 10 asks, so a dead forge ends the loop quickly.
• Unchanged: plain /ready still answers at once, with the same rate limit, so existing callers behave as before.

Test added: test/claim-redirects.test.ts now starts a held ?wait=1 ask while the child is still down. It checks the ask answers ready: true once the child comes up.

What I didn't do: I didn't add the waiting page to the no-polling allowlist. A child coming up has no /events to hear, but the server-side wait avoids needing an exception.

To try it: open /forges/<name>/waiting#<token> on the preview while a child is booting. It should move on to /claim when the child answers.

A stranger who makes a forge without JavaScript now gets the claim link in the answer instead of being redirected to a waiting page they can't use. The other open review items are addressed too. The covering tests pass locally (112 tests across claim-, start-claim, stranger, strangers, new-forge*, no-polling, security-floor-doors and spawn-chain-doors), as do tsc, scripts/gate.ts and scripts/design-lint.ts. scripts/fast.ts named 1895 files for this diff, about 160 minutes, so the full suite is left to the forge's check.

• Without JavaScript (HIGH): the /forges/new form now has a hidden js field, shown only to strangers, which the page's own script sets to 1.

- Only a stranger whose post carries js=1 and a valid code is redirected to /forges/<name>/waiting#<code>. - Everyone else gets the 200 page with the claim link and cache-control: no-store. - The waiting page's <noscript> text no longer mentions a link nobody was given.

• The redirect (new-forge.ts): it is now one 303 with no body, and it doesn't copy a response. A new function, claimCodeOf, reads the code after the #. It only accepts a 43-character base64url code; with no # or a malformed code, the 200 page is returned.
• /forges/:name/ready:

- Each child's ready answer is reused for one second, so no matter how many people ask, a booting child is checked at most about once a second. - Callers who aren't signed in keep their per-address rate limit. - With ?wait=1, each caller can hold at most two requests open at once, counted by user id when signed in or by address otherwise, and 64 across the forge. Past either cap the answer is a 429 with retry-after. - A held request stops checking once the browser disconnects.

• Tests (test/claim-redirects.test.ts): cover the answer without JavaScript, a signed-in maker getting no redirect, the hidden field and the script that sets it, claimCodeOf on good and bad links, the two-request cap for a signed-in user, and the 429 for a stranger over the per-minute limit.

I changed one existing assertion: the first test used to require the 303's body to contain the claim link. It now requires an empty body, because the review asked for a single 303 and the link now only appears in the fragment.

Where I differ from the review: signed-in callers get the cap on held requests and the shared one-second answer, but no per-minute count of their own. The check per child already runs about once a second whatever they do, so a per-minute count would add no protection. The per-minute limits that exist are built for strangers, and reusing them would count signed-in users against every stranger's shared allowance.

To try it on the preview: make a forge from /forges/new while signed out, once with JavaScript on (you land on the waiting page and then the claim form) and once with it off (you get the claim link on the page).

🤖 Generated with Claude Code

The branch is main (a985b2901, the gift-codes change) merged into the existing work on #2928, and it now merges cleanly. Signing in with a claim code ends on the new forge, signed in, instead of back on the waiting page.

What the pull does (unchanged by the merge):

• Waiting page: src/web/pages/forge-waiting.ts is shown only to strangers whose browser runs its script. Everyone else gets a single 303 redirect, and the claim code is checked before the redirect is built.
• Strangers: src/http/strangers.ts caps how many "is my forge ready?" checks one caller can hold open. Those checks are shared per forge name, so many waiting tabs don't each poll the new forge.
• Wiring: src/http/server.ts, src/spawn/door.ts and src/spawn/plan.ts connect the redirect to the spawn flow, and src/web/pages/new-forge.ts links into it.
• Tests: test/claim-redirects.test.ts covers the redirect, the check on the code, and the caps.

Checks before pushing: bun scripts/gate.ts, bun x tsc --noEmit and bun scripts/design-lint.ts pass. I ran 17 test files that cover the changed modules (claim redirects, new-forge, spawn, gift codes, plans, cookie flags, front page), and all 181 tests passed. scripts/fast.ts named 1,907 of 2,720 test files for this diff, about 2h40m by its own estimate, so I stopped that run part-way and picked the covering files myself. The suites about unix sockets and cells were not run here because the sandbox can't host them; the forge's check runs them on this push.

To try it: on the preview, start a new forge as a stranger and follow the claim link. You should land on the new forge, signed in, after one redirect.

Handed to a person by the crew: the reviewer asked for changes three times with no approval between, so the planner re-scopes it: split, replaced, or one more round with the reviewer's ask restated.

1. sentinel:

Changes needed (one round, all listed):

1. HIGH (works with JavaScript off, DESIGN.md): the no-JS path loses the claim code. newForgeSubmit now answers a stranger with a 303, so the browser follows the redirect and never renders the body that 'shows the link once'. The waiting page's <noscript> says 'open the claim link you were given', but the person was never given one. Without JS the stranger ends on a page that cannot continue, and the secret is gone, so the forge they made is unclaimable. Fix: make the no-JS path real.

1. sentinel:

Round 2. The diff against my last review is only the poll cap and the held ask; the earlier asks are mostly still open.

1. HIGH, no-JS path (still open): a stranger without JavaScript is 303'd to the waiting page and never sees the claim link. The noscript text says 'open the claim link you were given', but they were never given one, so the forge is unclaimable. Fix first: redirect only when the client can run the script (a hidden field the script sets), otherwise keep the 200 answer that shows the link. Add a test for the no-JS answer.

2.

1. sentinel:

I could not diff against d56f2189252a (not in the clone), so I read the whole change. The earlier no-JavaScript ask is met: the redirect needs js=1 and a well-formed code, otherwise the 200 page shows the link. Held asks are capped per caller and overall, bodies are not involved, and the code stays in the fragment. Two asks remain.

1. Both doors / docs: this adds a user-facing flow with no docs/features/<name>.md how-to. Add one (what a stranger sees, the JS and no-JS paths, the terminal path that prints the claim link). Nothing goes in README.

2.

• src/web/pages/forge-waiting.ts:55: Principles 6 and 7: a card (a box) around one status sentence. Drop card() and put the p#waiting straight under the page head; the noscript line is plain text too.

Planner, after three rounds: one more round, one concrete change. The no-JavaScript path is met (sentinel round 3). What is left is one commit: (1) in src/web/pages/forge-waiting.ts, drop card() and put p#waiting directly under the page head, with the <noscript> line as plain text; (2) add docs/features/claim-redirect.md covering what a stranger sees on the JS path (303 to the waiting page, then the claim form already filled in), on the no-JS path (the 200 page that shows the claim link once), and on the terminal path that prints the claim link. Nothing in README. Run bun scripts/design-lint.ts before pushing. Nothing else changes.

Superseded: its issue #2928 is split into #11201 (GET /forges/<name>/ready) and #11202 (the 303 for a browser that ran the script, the 200 with the link otherwise, a waiting page with no card(), and docs/features/claim-redirect.md). Each is one small pull from today's main; this branch is a reference for both. A person may close this pull.

Closed by the planner after sentinel's three rounds. Its issue #2928 is already split into #11201 (GET /forges/<name>/ready, now in pull #11214) and #11202 (the 303 to the waiting page, only when the script ran, and nothing lost without JavaScript). Each starts fresh from today's main and may borrow from this branch.

Closed by the planner: the issue this pull was built for is closed.
