Identical copies of _set_db_vars() and _strip_block() existed in phase1, phase2, and phase8. Moved to lib/common.sh as set_db_vars() and strip_template_block() (public API, no underscore prefix). Removed dead _strip_block definition from phase8 (defined but never called). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# This is the "go live" script — after this, Gitea is the primary git host.

# Caddy handles TLS automatically. TLS_MODE from .env controls how:

# "cloudflare" → DNS-01 via Cloudflare API (wildcard cert)
|

# "existing" → user provides cert/key paths
|
|
#
|
|
# After HTTPS is live, GitHub repos are marked as offsite mirrors.
