Wraps the gaps surfaced in the "what is not implemented" audit so the
fleet really is shippable end-to-end. Verified live on the Pi:
- cis490-shipper --ping → HTTP 200 through Caddy + mTLS via the
new wg-pki client CA leaf
- real episode dir → tar+zstd → PUT → HTTP 201 stored
- re-ship same bytes → 200 (idempotent)
- re-ship different bytes under same id → 409 (conflict)
Changes:
orchestrator/episode.py
- EpisodeConfig.revert_at_start / revert_at_end (Tier 0+ snapshot/
revert per docs/architecture.md). When set + qmp_socket present,
EpisodeRunner issues loadvm <snapshot_name> and emits
snapshot_revert / snapshot_revert_failed events on the same
monotonic clock as everything else.
collectors/qmp.py
- savevm() / loadvm() helpers using human-monitor-command, plus a
test against the fake QMP server.
exploits/workloads.py
- chunked_real_binary_upload() returns a ChunkedUpload plan: 8 KiB
base64 chunks (~6 KiB binary each) so msfrpc never sees a buffer-
busting payload. Includes a finalize step that sha256-verifies on
the guest before exec.
- real_binary_workload() now wraps the chunked plan for backwards
compat with single-shot callers.
exploits/driver.py
- Tier-4 dispatch walks the chunked plan in MSFExploitDriver:
each chunk is a separate session_shell_write; finalize verifies;
exec only runs on sha-ok. New events: real_binary_upload_begin,
real_binary_verify, real_binary_aborted.
etc/cis490-orchestrator.service
- Reads /etc/cis490/lab-host.env (FLEET_HOST_ID + optional BRIDGE).
- Grants AmbientCapabilities CAP_NET_RAW (tcpdump for source 4) +
CAP_SYS_ADMIN + CAP_PERFMON (perf for source 3) so collectors
work under hardening.
scripts/install-lab-host.sh
- Writes /etc/cis490/lab-host.env on first install with FLEET_HOST_ID
defaulting to `hostname -s`.
- Best-effort: fetches the Alpine baseline qcow2 (sha512-pinned) and
builds cidata.iso with the in-guest agent embedded; symlinks both
into /opt/cis490/vm/images/ so launchers find them.
scripts/fetch-alpine-baseline.sh
- Idempotent fetcher for the Alpine 3.21 cloud-init nocloud qcow2
matching the sha512 in docs/sources.md.
tools/plot_envelope.py
- Rebuilt to render whatever telemetry the episode dir contains:
proc → QMP block ops → perf IPC/miss-rate → bridge pkts/SYNs →
guest agent load/mem. Missing sources are silently skipped.
tools/index_reader.py
- cis490-index CLI: filter receiver's index.jsonl by host / sample
/ time range, sort, count-by group. Closest thing to a query
interface until we stand up Postgres/Timescale.
samples/README.md
- Rewritten to match the new manifest schema, the kind=real vs mimic
split, the per-(host, slot, ep) selection mechanic, and the
chunked-upload safety story.
Tests: 106 pass (was 102). New cases:
- test_qmp.py — savevm + loadvm (HMP wrapper + error path)
- test_tier4.py — chunked plan splitting, sha-pinned finalize,
end-to-end driver walks all chunks + verify + exec via the fake
msfrpc client
Closes the "what is not implemented" punch list.

orchestrator/
The state machine that drives a single episode:
snapshot_load → clean → armed → infecting → infected_running → dormant → reverting
Responsibilities:
- Bring up the host-only bridge and verify isolation before the guest starts.
- Boot the guest from a named snapshot.
- Spawn the five telemetry collectors (
collectors/) with a shared episode id and shared monotonic clock origin. - Drive the Metasploit Framework over RPC to fire the configured exploit module.
- Upload + execute the configured malware sample once a session is open.
- Emit phase transitions to
labels.jsonlat the moment the action is taken. - Revert the snapshot at episode end.
- Write
meta.jsonwith the result summary.
Implementation lives in this directory and is imported as orchestrator.*.
