The "Deploying the Scheduler" section predated scheduler-core and only
covered normal-mode startup. Adds session recording (--record-dir,
xceadmin scheduler record start|stop|status, filename validation),
xceadmin scheduler dump for offline .replay inspection, and simulation
mode (--sim, --sim-speed, --sim-verify, --sim-alt-events, --sim-output,
--interactive REPL) — all verified against the actual argp help output
and xceadmin cli.py source, not assumed.

trim_wal_segments + rotate_snapshots run on every checkpoint --
operators don't need to manually purge data/. Documents the
snap_keep_n=2 default and that it's a cluster-config field, not a CLI
flag.
--system-site-packages means pip skips vendoring click/pycapnp/pyyaml/
jsonschema since nix already provides them -- deliberate, to keep
pycapnp's ABI-sensitive build pinned to the exact capnproto C library
nix built it against. Activating the venv outside nix develop (or the
AppImage) hits ModuleNotFoundError immediately; not a packaging bug.
rshen/Letmein was a live, checked-in cluster_admin credential in
auth.yaml. Renamed to a non-identifying username with a clearly-marked
placeholder password.
docs: add full ops deployment guide (src/docs/deployment.md)
Covers building and running all four daemons plus xceadmin, based on
direct source verification (CLI flags, config file shapes, TLS posture)
and a live single-node deploy. Documents real production gaps (no
process supervision, plaintext non-controller traffic, exposed dev
creds) rather than treating the repo as a finished runbook.
