There was a problem hiding this comment.
If the provider sweep fails after beginDisablePublication commits, the row remains disabling. A retry reaches this lease acquisition, but claimVmPublicationOperation rejects both disabled and disabling rows as publication_not_active, so the sweep can never be retried. For a public publication, the Freestyle rule has no forward-auth gate and can therefore remain publicly reachable indefinitely; handle disabling as a resumable deletion state.

For a VM billed to a shared team, normal VM routes authorize it by billingTeamId, but publication reservation instead requires cloudVms.userId to equal the caller. Consequently, a team member can see and operate a team VM through cmux cloud list yet receives vm_publication_not_found when publishing it unless they happen to be the row's original creator. Resolve the selected account scope and authorize the VM by its billing team, as the other VM routes do.

There was a problem hiding this comment.
This call does not actually populate all teams in the current verifyRequest implementation: without a subrouterAuthorizationSignal, authedUserFromStackUser ignores listAllTeams and, when a selected team exists, skips user.listTeams() entirely. Therefore principal.teamIds usually contains only the selected team, and publishing or updating with --team for another team the user belongs to is incorrectly rejected as team_not_allowed. Use the full-team resolution path or resolve the requested policy team explicitly.

Every unauthenticated request to a protected publication inserts a transaction here, but expired or consumed transactions, codes, and sessions are only filtered during reads and are never deleted anywhere except publication/account cascades. Since an unauthenticated caller can repeatedly request a long-lived hostname, these tables grow without bound and provide a straightforward database-exhaustion path. Add bounded expiry cleanup or equivalent lifecycle enforcement.

Inline comments:
In `@CLI/CMUXCLI`+CloudDomains.swift:
- Line 3: Update validatedPublicationAccess to use VMPublicationAccessMode
directly and remove the separate CloudDomainAccessMode type, preserving the
existing validation behavior while allowing all modes supported by the shared
enum.
- Line 252: Update the DNS verification handling around the dnsInstructions
conditional so the verificationRecord fallback is evaluated independently when
verification lacks dnsInstructions. Ensure a verification containing only
verificationRecord still prints the DNS verification record, while preserving
the existing dnsInstructions behavior.
In `@web/app/api/vm/publications/routeShared.ts`:
- Around line 155-157: Update the action messages in the authenticated
publication route’s error response to remove CMUX_VM_PUBLICATION_AUTH_ORIGIN and
CMUX_VM_PUBLICATION_FORWARD_AUTH_SECRET, replacing both with product-level
guidance; retain the configuration names only in server-side logs or internal
telemetry.
- Around line 80-88: Update the forward-auth URL construction to require a
non-empty, valid HTTPS CMUX_VM_PUBLICATION_AUTH_ORIGIN; do not fall back to
request.url or return an empty/malformed URL. In the origin-resolution logic,
throw PublicationConfigurationError with reason "invalid_auth_origin" when the
configured origin is absent, invalid, or non-HTTPS, while preserving the
existing forward-auth path and serviceToken.
- Around line 92-101: Update publicationErrorResponse to resolve the request
locale and load the localized message and action values from web/messages for
every supported locale, replacing the English fields returned by inputErrorCopy.
Preserve the existing error code, reason, field details, and 400 response while
ensuring the locale-aware values are sent to HTTP clients.
In `@web/app/cloud/access/access-card.tsx`:
- Line 86: Update the signed-in message formatting in the component rendering
messages.signedInAs to use a replacement callback returning identity, preserving
identity values containing replacement tokens literally; add a regression test
covering an identity with a replacement-pattern value.
In `@web/app/env.ts`:
- Line 254: Update the CMUX_VM_PUBLICATION_AUTH_ORIGIN schema entry to fail fast
during startup by validating that configured values are HTTPS URLs with no path
component, while preserving its optional behavior.
In `@web/messages/de.json`:
- Around line 65-70: Update the user-facing strings around title, signedOutBody,
and invalidBody in de.json to use formal German address: replace informal “du”
forms with “Sie” forms while preserving the existing meaning and placeholders.
In `@web/services/vm-publications/auth.ts`:
- Line 164: Update the authorization flow around
PublicationViewerResolver.resolve so membership resolution occurs only for team
publications; personal-session decisions should use principal.session.userId
directly and never call resolve. Add a regression test confirming an allowed
personal session does not invoke PublicationViewerResolver.resolve.
In `@web/services/vm-publications/provider.ts`:
- Around line 602-605: Update both TLS rule listing call sites in the provider
flow (the teardown logic around listed/ruleIds and the reconciliation logic
around lines 635-640) to use one shared pagination helper that repeatedly calls
client.tls.rules.list with limit and offset until totalCount is covered, then
filter the complete rule set. Apply the helper at both affected locations in
web/services/vm-publications/provider.ts.
- Around line 345-352: Update publicationTlsRuleOptions to reject a
trimmed-blank spec.forwardAuthId before constructing or reconciling the TLS
rule. Preserve public access only when forwardAuthId is null or undefined, and
ensure protected publications never omit forwardAuth after
ensureSharedForwardAuth returns an invalid blank identifier.
In `@web/services/vm-publications/workflows.ts`:
- Around line 566-571: Update longestCoveringDomain to filter custom domains by
verificationState === "verified" in addition to provider and hostname coverage,
so sorting selects the longest verified covering zone while excluding pending or
failed zones. Preserve the existing null fallback when no verified candidate
exists.
In `@web/tests/vm-publication-access-localization.test.ts`:
- Around line 77-82: Update the translation-difference assertions in the locale
test so the access title and sign-in copy not.toBe checks run only for the
explicitly high-confidence locales, rather than every locale except English.
Keep the existing non-empty and placeholder validations applied to all locales,
using the existing locale or confidence symbols where available.
In `@web/tests/vm-publications-db-behavior.test.ts`:
- Around line 49-55: Update the negative-operation helper so the awaited
operation is caught and matched without allowing the “expected repository
operation to fail” sentinel thrown after a successful operation to enter the
same catch block; place that sentinel throw outside the try/catch while
preserving the existing expected-error assertion.

Prefer a verified covering zone over a longer unverified one.
longestCoveringDomain filters only on provider and kind. It ignores verificationState. If the owner holds a longer covering zone that is pending or failed, that zone wins over a shorter verified zone.
reservePublication then attaches the publication to the unverified zone, because it checks coverage only. provisionReservedPublication rejects the publication at Line 643 with publication_not_active. The owner must complete DNS for the deeper zone, even though a verified covering zone already exists.
Restrict the candidate set to verified zones so the documented wildcard-reuse path is selected.

Scope the translation-difference check to locales that require translated copy.
The locale !== "en" guard makes Line 82 fail when lower-confidence locales such as ar, bs, km, or th legitimately use an English fallback for a new key. Keep the non-empty and placeholder checks for every locale, but run the not.toBe assertions only for the explicitly high-confidence locales.
Based on learnings, lower-confidence locale files may use English fallback, while only explicitly high-confidence locales must contain translated new copy.

…ew findings Generated publication hostnames now live under a CMUX-owned zone, cmux.sh by default and overridable with CMUX_VM_PUBLICATION_GENERATED_DOMAIN, instead of Freestyle's free style.dev zone. The zone is ordinary verified account inventory: its wildcard certificate must be live before a generated name activates. The zone apex, everything below it, and one-label style.dev names are rejected as custom hostnames. Review fixes (Codex, CodeRabbit, and a follow-up audit): - forward-auth: the account-wide Freestyle target only ever derives from CMUX_VM_PUBLICATION_AUTH_ORIGIN, validated as a bare https origin at startup. The request URL is never consulted, and the edge route fails closed with 503 when the origin is unset. - publish authorizes the VM by the caller's billing scope like every other VM route: team members can publish team-billed VMs, ex-members cannot. - the requested teamId is resolved before authentication so --team accepts any current team, not only the selected billing team. - an owner delete resumes a publication left `disabling` by a failed sweep. - Freestyle TLS rule listings are paginated; VM and account teardown sweep every hostname with one listing; account deletion never re-sweeps a disabled publication whose hostname another account may now own. - expired or consumed auth transactions and sessions are retired on the hot path, and pending transactions are capped per publication. - non-navigation requests receive 401 without minting a transaction, the callback only completes for GET/HEAD, personal sessions skip Stack team enumeration, a blank forward-auth id can no longer publish a protected rule, and a verified covering zone wins over a longer pending one. - client error copy no longer names environment variables, the access card renders identities containing `$` patterns literally, the access page honours the proxy-resolved locale, and the CLI drops unreachable legacy DNS fallbacks.

Generated publication names now read like `laughing-green-elephants.cmux.sh` (descriptor, colour, plural animal) instead of a hex label. Users cannot choose a label under the generated zone; custom hostnames come from their own verified domains via `--domain`. When a friendly name collides with another account's claim, the publish mints another one, adding a short random suffix after a few tries, so the database's global hostname claim stays the arbiter and a customer never sees another tenant's random collision. `cmux cloud domains custom` (socket `vm.domain_list`, `GET /api/vm/domains`) lists the custom zones an account owns apart from its publications: the zone's verification and certificate state, the zone-level TXT proof and `_acme-challenge` delegation while verification is pending, and the publications routed through it with a verify hint for the first one that is not yet active. Per-hostname routing records stay on `list`. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QRgeJamB8kV7PH5iCdbLQU
Replace the hand-rolled word lists with the `unique-names-generator` dictionaries (adjective, colour, animal), filtered to lowercase ASCII words at load time so every generated label stays DNS-safe.

Note GitHub couldn't provide a complete incremental comparison for this pull request, so CodeRabbit is performing a full review instead. This review may take a little longer. |
`cmux cloud domains verify <domain>` is now the zone-level verb. The first call mints the Freestyle challenge for a zone the caller owns and prints the TXT proof and `_acme-challenge` delegation; later calls try to complete it, and a rejected completion reports the zone as still pending instead of a provider failure. Once verified, the command requests the zone's wildcard certificate and provisions every publication that was reserved on the zone before it was verified. A name that matches one of the caller's live publications refreshes that publication instead, so generated names use the same verb. `access` and `rm` accept a publication's hostname as well as its id, and a bare generated label is completed with the generated zone. The publication listing is `list`; the zone listing is `zones` (alias `custom`). Every DNS hint in the CLI now names the domain to verify rather than a database id.

Add an edge rate limit for authorization transaction creation.
Unauthenticated GET and HEAD requests reach beginPublicationAuthorization and perform a database insert. The repository caps pending rows at 1,000 per publication by deleting the oldest rows, but repeated requests still cause database churn and can evict unrelated in-flight sign-ins. Apply the rate limit before transaction creation; changing the trim behavior alone does not prevent this.

Validate providers before freezing publications.
freezeVmPublicationsForDeletion durably changes rows to disabling before this branch checks publication.provider. For a non-freestyle row, the function returns before deleting provider TLS rules or calling finishDisablePublication. The provider TLS rules remain in place, and each retry can return the same error. Validate providers before the state update.

`cmux cloud domains verify <domain>` no longer doubles as a publication refresh. It always verifies a zone: a publication hostname or id resolves to the zone it belongs to, and a generated name is rejected with `verification_not_required` because there is nothing to verify. Re-running verify on a verified zone re-checks its certificate and finishes provisioning the publications on it, so the CLI hints point at the zone in both cases. The socket method and REST route answer with the zone only. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QRgeJamB8kV7PH5iCdbLQU

`verify <domain>` and `zones` now print the zone's complete DNS work as an aligned table headed "Add these DNS records for <domain>:", each row labelled ownership, routing, or certificate. The server includes both routing records in the zone's checklist: the apex ALIAS/ANAME record for publishing the domain itself and the `*` CNAME that covers every subdomain, so one DNS session prepares a domain for any publication on it. The per-hostname table printed by `publish` and `list` uses the same format.

Freestyle documents the apex as an ALIAS/ANAME/CNAME-flattening record and lists no stable edge IPs outside its dashboard, so the checklist never offers an A record. Providers without such a record type get the documented fallback instead: publish www.<domain> and redirect the apex to it.

- forward-auth: split request evaluation from transaction minting so the one write an anonymous navigation can cause is gated by a Vercel Firewall rate limit keyed by hostname and the relayed browser address (CMUX_VM_PUBLICATION_SIGN_IN_RATE_LIMIT_ID); allowed session traffic is never limited. - pending sign-in cap: retire abandoned transactions (older than two minutes) first and refuse the newcomer when the cap still holds, instead of evicting someone mid sign-in. - Freestyle rule listing: treat a scan as valid only when every page agreed on totalCount and no id repeated; repeat unstable scans and fail closed after three, so a mid-scan create or delete cannot yield a partial snapshot. Hostname sweeps use set membership. - account deletion: a custom zone drops its verified claim so the next DNS owner can verify it again; generated names stay reserved forever. - verify/zones: keep the checklist visible until the certificate is live; domain-scoped publication query for provisioning and listing; Map grouping for the zone listing; generated zone capped at 200 characters; CLI error copy for a domain response; deterministic friendly-name test.

Add web/scripts/vm-publication-smoke.ts, a read-only-by-default check of the generated zone (ownership, wildcard certificate, rule pagination, certificate resolution) with an opt-in mutation phase that creates and then removes a verification challenge, a forward-auth config, a throwaway VM with a listener, and a TLS rule for a generated hostname fetched over HTTPS. Observed live: a missing TXT proof fails completion with `400 VERIFICATION_FAILED`, so the provider now treats only that code and a withdrawn challenge's 404 as "still pending"; every other rejection is a provider failure. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QRgeJamB8kV7PH5iCdbLQU
Add web/scripts/vm-publication-custom-domain-smoke.ts, which drives the custom-domain flow step by step through the real repository and provider: verify (start, then complete once DNS is in place), publish to a throwaway VM, switch access, list, and clean up. Run against cmux.swerdlow.dev on 2026-09-03: ownership verified on the second `verify`, the `*.cmux.swerdlow.dev` wildcard was issued within a minute, the zone apex activated after its own certificate issued, and a child hostname activated immediately under the wildcard; both served 200 over TLS. A freshly requested wildcard now reports `pending` instead of `missing` while Freestyle's certificate inventory lags the request. Attaching forward-auth to a TLS rule currently fails on Freestyle's side with `503 INTERNAL_ERROR` for both create and update, so `updatePublicationAccess` correctly left the publication public; protected publications are blocked on that until Freestyle fixes it.

…f tooling The hot-path sweep deleted consumed transactions immediately, which cascaded away the authorization code the browser was about to present at the callback. A consumed transaction now lives until it expires; only expired rows are retired. The forward-auth route logs a tagged error's reason instead of the generic message. Add web/scripts/vm-publication-forward-auth-server.ts, which serves the real forward-auth route standalone so Freestyle's edge can be pointed at a development machine through an HTTPS tunnel, and give the custom-domain flow driver `lock`/`unlock` steps plus a configurable authorizer URL. Verified live on 2026-09-03 against cmux.swerdlow.dev: anonymous GET relayed as a 302 with the host-only transaction cookie, POST refused with 401, callback exchanged into a session cookie through the edge, session admitted to the VM (204 -> 200), forged session sent back to sign-in. Smoke timeouts are now 5s per request with 2s retries. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QRgeJamB8kV7PH5iCdbLQU

Attaching forward-auth initially failed with
