## Direction-2a agent-plane immediate-sync — poke sender + ep0 felhom-poke surface (hub v0.59.0) — 2026-07-16

**Baseline:** hub v0.58.0 → **v0.59.0** (LIVE on prod, ArgoCD Synced/Healthy). Pairs with felhom-agent
v0.89.0 (the poke listener). Green gate `go build ./... && go vet ./... && go test ./...` passes.
Design contract: `documentation/audits/SPIKE-immediate-sync-transport-2026-07-16.md` option (a).

### What shipped
- **`internal/poke`** — the SSH poke SENDER (third sibling of `internal/wgsync`/`internal/tenantsync`):
  a pinned-host-key (algorithm-pinned `ssh.FixedHostKey`) in-process client reusing the peersync
  endpoint + host key, its OWN forced-command key. `Client.Poke(ctx, boxWGIP)` refuses any target
  outside `10.77.0.0/24` BEFORE dialing, then SSHes to ep0's `felhom-poke` with the box WG /32 as the
  command string (→ `$SSH_ORIGINAL_COMMAND`) which sends one empty UDP datagram to `<ip>:51822`.
  `Notifier.PokeHost`/`PokeAllHosts` are fire-and-forget (detached goroutine, nil-receiver-safe) — a
  poke never blocks or fails the operator save; a missing peer / SSH error is logged, the report cycle
  reconciles. Tests: resolved-IP send, no-peer / store-error no-send, nil no-op, `Poke` pre-dial
  non-WG refusal.
- **Wiring:** `Server.SetPoke`; `applyPBSDR` fires `PokeHost(host.HostID)` after each generation-bumping
  descriptor save; `handleSetArtifacts` (MinAgent-floor save) fires `PokeAllHosts()`. `cmd/hub/main.go`
  env-configures the sender (`POKE_SSH_KEY_FILE`, reusing `WG_ENDPOINT_SSH_ADDR`/`_HOSTKEY`/user).
- **ep0 surface:** `scripts/felhom-poke.sh` v1.0.0 — a NON-root (`felhom-peersync`, no sudoers grant)
  forced command that validates `$SSH_ORIGINAL_COMMAND` to the WG /24 and sends one empty datagram
  from wg0. Contentless + confined (the WG kernel refuses non-peer /32s — spike P1 EKEYREJECTED).
  Runbook `documentation/runbooks/offsite-endpoint.md` §11. Port **51822** = shared cross-repo constant.
- **`manifests/hub.yaml`:** `POKE_SSH_KEY_FILE` env + optional `Secret/agent-poke` mounted 0400; image
  tag `0.58.0`→`0.59.0`.

### Landmarks as found at source
- **Poke wiring is host-keyed** (`store.GetWGPeerForHost` → the box WG /32), the sibling of the
  customer-keyed `internal/intent` long-poll (Direction-2b / controller plane). `SetHostDesired` bumps
  the poked host's generation; the poked immediate report carries the advanced envelope generation →
  the agent fetches the new descriptor.
- **Spec-vs-source note (source wins):** the MinAgent-floor / artifact-manifest save
  (`handleSetArtifacts`) does NOT itself bump per-host desired generation — the agent self-update
  dispatches via signed-ops on the next report — so `PokeAllHosts()` there accelerates the next report
  cycle where the floor is applied, rather than delivering a desired-state delta. Kept the poke there
  (the spec names this handler) and documented the semantics.

### Live validation
- **Deployed:** hub 0.59.0 built + pushed on 180, manifest tag bumped + ArgoCD synced (Synced/Healthy,
  rollout complete, image `:0.59.0`); after the Secret was created it logs `agent-plane poke enabled`.
- **ep0 poke surface installed live** (additive; `felhom-peersync` authorized_keys 2→3 lines,
  peersync/tenantsync UNCHANGED; `/usr/local/bin/felhom-poke` 0755; `Secret/agent-poke` holds the
  private key, the build-server copy shredded).
- **ep0 leg live-validated with the poke key:** a valid WG target (`10.77.0.2`) → `poke-fired`;
  `8.8.8.8` AND `rm -rf /` as the SSH command → `refused non-WG target` (the forced command NEVER
  executes client input, only reads it as an IP candidate). This proves the full hub→ep0→box datagram
  path and the credential-theft blast radius (≤ "make a registered box tick").
- **Fired end-to-end from a REAL operator save (2026-07-17):** the operator's Day-0 manifest save
  (`Artifact manifest set: agent=0.89.0 … min_agent=0.89.0`) immediately logged `poke: sync-poke
  delivered to 10.77.0.2 via 167.233.158.164:22` + `fleet nudge sent to 1/2 WG peers` — the
  `handleSetArtifacts`→`PokeAllHosts()` wiring proven live to the box (the 2nd peer is offline). The
  MinAgent-floor coupling also fired: `managed floor HELD for demo-felhom: agent 0.88.0 < MinAgent 0.89.0`.
- **Scenario 3 box-side latency measured** once the demo reached v0.89.0: a poke ep0→box delivered in
  **~31 ms** and fired the immediate desired-state cycle (see the felhom-agent REPORT). Full save→tick
  ≈ ~0.45 s (SSH-dominated), well under the ≤2–3 s target. All three live legs (Scenario 4 A/B train,
  Scenario 1 R-22 self-heal, Scenario 3 latency) are proven-live; the capability-map poke + F4 rows are
  upgraded to PROVEN-LIVE.
