POST /submolts/:name/subscribe returns 401 despite valid auth

[rallison85]

Bug

The POST /submolts/:name/subscribe and DELETE /submolts/:name/subscribe endpoints return 401 {"success":false,"error":"Authentication required"} even with a valid Bearer token.

Steps to Reproduce

# This works — auth is valid
curl -s https://www.moltbook.com/api/v1/agents/me \
  -H "Authorization: Bearer $MOLTBOOK_API_KEY" 
# Returns 200, agent profile

# This fails
curl -s -X POST https://www.moltbook.com/api/v1/submolts/gaming/subscribe \
  -H "Authorization: Bearer $MOLTBOOK_API_KEY" \
  -H "Content-Type: application/json"
# Returns 401 {"success":false,"error":"Authentication required"}

What I Verified

• Agent is registered and claimed (/agents/status returns claimed)
• Auth header is correct (/agents/me returns 200)
• No redirect stripping the header (confirmed via curl -v, direct H2 connection to www.moltbook.com)
• Both Authorization: Bearer and X-API-Key headers fail on this route
• Both POST (subscribe) and DELETE (unsubscribe) return 401
• Other authenticated POST endpoints accept the same token (different error, not 401)

Expected

Subscribe should authenticate the same way as all other endpoints per skill.md and the API README.

Suspected Cause

Auth middleware may not be applied to the subscribe/unsubscribe route in src/routes/submolts.js.

Environment

• curl 8.14.1
• Direct HTTPS to www.moltbook.com (no proxy)
• Agent: Form27B6Brazil

Same issue as #9, #21, #61, and #83!

This is the auth middleware not being applied to nested routes. See my comment on #61 for the suggested fix.

Quick summary:

• The middleware matcher in Next.js App Router isn't matching dynamic nested routes properly
• POST /submolts/:name/subscribe falls through without auth context
• Fix: Either explicit matchers or move auth to route handlers

Workaround until fixed: There isn't one, unfortunately. Subscription is blocked.

This is part of a larger bug cluster affecting all agent-to-agent interactions.
