Why:
svc.sh only managed agent-system environments; databases, standalone
frontend serving, per-service tags and reusable start configs were out of
scope, and the user asked for a unified service lifecycle on this host.
Evidence:
- Service model v2: kind=agent|static|postgres registered in
runtime/<name>/svc.env (dotenv, mode 600); legacy entries without kind=
are adopted as agent.
- postgres: "db create <name> --port/--user/--password/--db/--auth-mode/
--tag" runs initdb (scram-sha-256, pwfile 0600), start/stop/restart use
pg_ctl (-m fast, never SIGKILL on postmaster) with pg_isready checks and
first-start database creation; "db dsn <name> [--reveal]" prints a
composable DSN (password masked by default). Verified end to end against
a real postgresql@18 instance: data survives restart, wrong passwords
rejected, stop/restart clean.
- static: "deploy --kind static --from dev[@sha]|local" builds frontend
dist into htdocs/ in an isolated worktree, or "--dir PATH" serves an
existing directory; verified serving HTTP 200, restart, stop, dry-run
plan, and explicit rejection of release sources.
- agent: unchanged three deploy sources plus --tag; bare start/restart now
reuses the persisted exec= from svc.env (verified: same custom port and
args across restart); old binaries lacking --dsn/--auth get those flags
auto-omitted with a warning.
- "list|status [--tag]" shows NAME/KIND/STATE/PID/ADDR/SOURCE/TAGS for all
registered services; "<name> status" gives per-kind detail; "rm <name>
[--purge]" unregisters (and optionally deletes) only runtime/<name>/.
- Fixed during verification: psql arg mangling (-c -c), tags lost because
record_state read svc.env inside its own redirect block, postgres
--version field parsing, unbound vars for unregistered names.
Impact:
Same invariants as before: writes stay under runtime/<name>/ and
runtime/.worktrees/ (only --from local also writes main-checkout build
outputs, all gitignored), stops only own pidfile+cmdline-verified
processes, port conflicts reported not seized. Prompt output moved to
stderr so stdout (tables, DSNs) stays pipeable. Makefile gains svc-list.
