fix(collab): allow hosted app origins - #2011
Conversation
The production web and studio hosts were missing from the relay defaults, causing session creation to fail with HTTP 403. Keep both relay implementations aligned and cover the hosted origins with a regression test.

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The PR broadens collaboration session creation to hosted origins and aligns relay defaults, but the documentation still omits the exact accepted preview host patterns. This is a bounded follow-up risk requiring owner awareness; the PR is otherwise mergeable. Possibly related PRs

Code reviewReviewed the diff adding Bugs: None found. The origin check uses exact Security: None found. The three added domains are verified as legitimate hosted origins elsewhere in the repo ( Performance: No concerns; the allowlist is a small fixed array checked linearly, unaffected by this change. Quality: The two relay implementations ( CLAUDE.md: No violations. No inline comments were posted — this is a small, well-scoped, low-risk change with adequate test coverage on the side that has tests. |

Note GitHub Pages built this preview successfully, but its serving edge returned HTTP 403 when checked. The links may still be propagating. |
PR previews run on the project-owned Cloudflare Pages hostname and opengeos.org, so the production relay must accept those origins too. Keep custom operator allowlists authoritative and reject look-alike preview domains.
- Document every default collaboration origin category so the operator note matches the relay policy.

In `@docs/collaboration.md`:
- Around line 260-263: Update the browser-origin filtering documentation near
the hosted app origins to explicitly allow the HTTPS opengeos.org host and the
one-level *.geolibre-preview.pages.dev preview-host pattern, while retaining the
existing hosted, localhost, Cloudflare, and GitHub Pages origin descriptions.
Apply the same fix in `@docs/collaboration.md` around lines 260 - 263.
In `@workers/collab-node/test/relay.test.ts`:
- Around line 128-132: Extend the negative origin test around
rejectedPreviewLookalike to submit a request from the nested host
a.b.geolibre-preview.pages.dev and assert HTTP 403, while preserving the
existing outside-suffix case.
In `@workers/collab/src/index.ts`:
- Around line 67-73: Restrict preview-host matching to exactly one subdomain
label before geolibre-preview.pages.dev instead of accepting any host that
merely ends with that suffix. Apply the same host-depth validation in the host
checks of workers/collab/src/index.ts (lines 67-73) and
workers/collab-node/src/server.ts (lines 81-87); retain the existing
opengeos.org and HTTPS conditions.
- Around line 67-73: Make the configured ALLOWED_ORIGINS allowlist take
precedence over the local-origin bypass in both relay implementations: update
workers/collab/src/index.ts lines 67-73 and workers/collab-node/src/server.ts
lines 81-87 so the local exception is evaluated only when using default origin
rules, while preserving allowlist evaluation for custom configuration.

- Remove blanket trust for the shared opengeos.org preview origin. - Restrict Cloudflare previews to one label, HTTPS, and the default port. - Make custom ALLOWED_ORIGINS settings authoritative over local defaults. - Cover nested, custom-port, shared-host, and configured-origin cases. - Document the exact default preview-origin policy and exclusions.

Unbalanced parentheses: the outer (defaults to the hosted origins …) parenthetical already closes right after `tauri://localhost`). The ) at the end of this line has no matching (, so the sentence reads oddly (… not trusted) as browser-origin filtering). Confidence: high (verified by counting the parens through this whole note).
