- migrations: MIGRATION_TABLES now equals POSTGRES_SCHEMA tables
(uploads, task_attachments, task_followups, environments added);
SEQUENCE_TABLES matches IDENTITY tables; task_followups
sender_task_id column ensured before insert; UNMIGRATED_TABLES
and migration_coverage() report tables with no PG schema instead
of silently skipping them; CLI prints the coverage report.
- deploy: DEFAULT_TEST_SUITES gains deploy/tests (discover -s only,
never package path); regression tests pin the default list.
- monitor: MONITOR_SINGLE_HOST=1 makes the server check single-host;
default stays dual to avoid silent downgrade; server_mode is in
the JSON. Optional fail-only alert outlet (webhook or mail,
default off, alert body is pass/fail JSON only, no secrets).
- backup/rollback: README and restore-drill document what is
recoverable (DB, code) vs not (worktrees, traces, uploads, host
configs); rollback.sh shares the server-unit list and dual-port
health success standard with host_deploy.sh (sync test guards it).
- public entry: Caddyfile uses native {$DOMAIN}/{$ACME_EMAIL}
variables plus a caddy.service template; README documents the
steps and the current BT-nginx production status.
