Document space.fast defaults and retained view.fast URLs

[batuhan]

New Spaces use space.fast; existing Spaces on view.fast keep their addresses. Update the default-hostname guidance and new-publish examples, explain retained version and branch URLs, and include both managed domains in sandbox allowlists and domain-protection guidance. Existing-space examples remain on view.fast.

Refresh the complete exporter-owned public snapshot, including the API, CLI, errors, setup instructions, changelogs, and redirects. Keep its files verbatim. The snapshot now includes 435 API operations, 415 platform API operations, and 673 error codes, including configuration-only publishing and its missing-artifact recovery guidance.

Keep validation accurate for the refreshed contracts: distinguish UUID literals from short commit hashes, allow exact external protocol terms only in compatibility API fields, recognize the current product vocabulary and quoted enum identifiers, and preserve historical release-note terminology. Behavioral tests exercise both checkers and their rejection paths. Remove 65 stale platform-reference aliases whose session-only destinations are outside the current platform API reference; retained aliases continue to resolve.

Ship these docs after the production default has changed and a publish on the new domain succeeds.

Validation: Bun 1.3.11 frozen install; exporter freshness check; generated snapshot verification; command examples; strict type checks and link validation; static build; built-site audit; public safety; Vale prose checks; route verification; and both checker regression tests passed. Route verification covers all 90 authored routes and 3,186 compatibility URLs.

Issues

2 potential issues found:

• The sf spaces claim and sf continue sample outputs still print docs.view.fast. Only unclaimed anonymous Spaces can be claimed, and after the cutover those are on space.fast, so the samples contradict the updated anonymous-and-claim page. See content/cli/spaces.mdx:250 and content/cli/agent-commands.mdx:165.
  _{Found by Indent Review Agent}
• The refresh deletes the space_quota_exceeded, deploy_quota_exceeded and build_minutes_quota_exceeded reference pages, but hand-written pages (api/errors.mdx, usage.mdx, limits.mdx, anonymous-and-claim.mdx) still tell readers to match on those codes. The docs now contradict their own error reference.

1 issue already resolved

• The refreshed OpenAPI snapshots give immutableUrl as https://v1--marketing-site.space.fast/ (10 occurrences), the legacy prefix format on the new apex. urls.mdx says new Spaces use {label}--v{number}.space.fast, so the API reference shows a hostname that never resolves. (fixed by commit d7bfb12)

📝 Walkthrough

Walkthrough

The documentation now describes space.fast hostnames for new Spaces and updated version and branch URL formats. It also documents that existing Spaces retain their hostname formats and updates publish examples, troubleshooting guidance, and hostname evaluation expectations.

Changes

Managed Space hostname documentation

Layer / File(s)	Summary
Hostname and URL rules content/(concepts)/spaces.mdx, content/(concepts)/versions.mdx, content/(serve)/urls.mdx, content/(serve)/domains.mdx, content/quickstart.mdx, content/troubleshooting.mdx, evals.yaml	The guides describe space.fast for new Spaces, updated version and branch URL formats, and continued support for existing hostnames. They also document hostname reservation, renaming, custom-domain behavior, and allowlist guidance. The hostname evaluation expectations now reflect the updated formats.
Publish examples and receipts content/(publish)/anonymous-and-claim.mdx, content/(publish)/recipes/*, content/api/index.mdx, content/cli/publish.mdx, content/index.mdx, content/quickstart.mdx	Publish receipts and examples use space.fast live URLs and the updated version URL format. The claim comparison refers to the Space’s managed hostname. The quickstart states that the managed hostname continues to work after a custom domain becomes the Live URL.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🔵 Low · up to f5b65

One hostname evaluation may mis-score a correct answer about existing Spaces. The issue is limited to evaluation reliability and straightforward to correct, so overall merge risk is low.
