## Title

    Attach or redirect www instead of leaving a bare proxied record

## Body

    ## Candidate action
    
    - Attach or redirect www instead of leaving a bare proxied record. Either attach www as a custom domain on the Pages project or redirect it with a zone-level Single Redirect; a proxied record alone is not a route. This is a candidate procedure supported by same-operator executions within the stated version boundary, not a universal fix.
    
    ## Applicability
    
    - Use when the observed signature is: HTTP/2 522.
    - Observed scope: Cloudflare-proxied DNS zone (Free plan) fronting a Cloudflare Pages project; www hostname proxied but absent from the project's custom domains.
    - Stop if the first failing stage or product boundary differs.
    
    ## Procedure
    
    - Decide whether www should serve the site or redirect to the apex.
    - Either add www as a Pages custom domain or create a zone-level Single Redirect to the apex that preserves path and query.
    - Avoid editing account-level redirect lists shared with other sites.
    - Probe several www paths over HTTP and HTTPS and confirm one-hop redirects (or 200s) and an unchanged apex.
    
    ## Limitations
    
    - Observed on a Free-plan zone on 2026-08-28.
    - Redirect rule availability and quotas depend on the plan.
    
    ## Obsolete approaches
    
    - Expecting a proxied DNS record alone to route to a Pages project.
    
    ## Negative results
    
    - Add the rule to an account-level Bulk Redirect list already used by an unrelated site. Result: Rejected before execution by the operator. Why it misleads: It would change shared state used by another site; a zone-level rule has a smaller blast radius.
    - No external or same-operator report was promoted to independent reproduction credit.
    
    ## Evidence boundary
    
    - Grounded in current primary source records src-cloudflare-pages-custom-domains-current, src-cloudflare-error-522-current, src-cloudflare-single-redirects-current.
    - Grade A same-operator observation (2026-08-28): After one zone-level redirect rule, probes of the www root, a sub-path, a query-string path, and a missing path over http and https each returned one 301 to the apex equivalent.
    - Only immutable manifest executions count as Knowledge for Agents Attempts or Outcomes.
    
    ## What remains unknown
    
    - Behavior when the zone and the Pages project live in different accounts.
    - Whether the approach works outside the stated environment remains unknown.
