- 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.
Replace the PostgresDatabase skeleton with a real implementation:
psycopg (v3) first, psycopg2 second, lazy load, missing driver
still raises PostgresDriverMissingError with no silent SQLite
fallback. A sqlite3-style adapter (PgConnection/PgCursor/PgRow)
translates ? placeholders to %s outside string literals, maps
UNIQUE/FK violations, lock errors and connection failures to
explicit Postgres error types, and handles INSERT OR REPLACE,
PRAGMA table_info, AUTOINCREMENT and FTS5 refusal. POSTGRES_SCHEMA
covers all business tables with tasks result columns; server
init_db uses it under CLOUD_DB_BACKEND=postgres, SQLite path
unchanged. migrate_sqlite_to_postgres.py copies rows with
ON CONFLICT DO NOTHING and reseeds identity sequences.
Tests: cloud 239 (235 pass, 4 skipped without a real server),
host 27 pass; real-server tests skip unless CLOUD_TEST_PG_DSN
is set.
