D1: Iroh endpoint + relay + mDNS discovery

Iroh endpoint bound to spt-proto Ed25519 identity (Spike #2 shape). n0 relay default + self-host knob + disclosure (REQ-NET-2). mDNS LAN discovery + connect on net ALPN. Acceptance: two local nodes discover + connect, E2E. Activates REQ-NET-1 impl/unit + REQ-NET-2.


2 pass, mDNS ignored. Now actually validating the mDNS test locally (my comment claims it — must verify). Wrapping in a timeout so a multicast hang can't block.

mDNS LAN discovery + connect-by-id **passes locally** (3.1s) — claim verified. D1 complete (a/b/c). Confirming gate green, then committing D1c.


cd "C:/Users/decid/Documents/projects/spt-core" && traceable-reqs check >/dev/null 2>&1; echo "trace=$?" && git add crates/spt-net && git commit -q -F - <<'EOF'
feat(net): M4-D1c mDNS LAN discovery + connect-by-id

Add mDNS (swarm-discovery) as an extra address-lookup alongside the preset's
n0 DNS, via a LocalDiscovery {Mdns | Off} bind knob. With mDNS on, a node
advertises itself and resolves peers by id on the LAN, so NetEndpoint::
connect_by_id dials a peer knowing only its node id (public key) — no address
ticket, no relay round-trip. This is the "two machines on one LAN find each
other" path the WAN ticket exchange doesn't need.

mDNS test connects server<-client by id alone (relays disabled, mDNS only) and
asserts the echo. It is #[ignore]'d because CI sandboxes don't reliably pass
LAN multicast; validated locally 2026-06-03 (single-host multicast, 3.1s, PASS).
The two hermetic tests (identity-binding, loopback-by-address) stay in CI.

Covered by REQ-NET-1 (impl/unit) already active; no stage change. check green,
non-ignored tests pass, ignored mDNS test passes locally, traceable-reqs green.

**M3 COMPLETE + CI-green (2026-06-03).** M3a + M3b + M3c shipped on `dev-freeform`
(M3c = fe0acce→a14639a, CI run 26901923120). Full ADR-0004 architecture live.

**M4 (`spt-net`) STARTED 2026-06-03** (user gave explicit go). Done so far on
`dev-freeform`:
- **Plan expanded** (commit ca6522b): `M4-PLAN.md` Tasks now a full D0–D9
  breakdown with sub-tasks, requirement→task map, and a binding red-team
  obligations table (pairing #10 seed-rotation / #11 rate-limit / #12 transcript;
  instances #7 merge-clock / #8 epoch-lease / #9 dormant-budget; #6 failure-domain).
- **D0 scaffold** (commit c47d2c6): `crates/spt-net` created, wired into workspace,
  whole transport behind default-on `net` feature (ADR-0002). check green (default
  + `--no-default-features`), layering acyclic, `traceable-reqs check` green. No REQ
  activated yet (rule 5 — scaffold delivers none; REQ-NET-1 lands at D1).

**NEXT = D1** — Iroh endpoint (reuse spt-proto Ed25519 identity, iroh 0.98 / Spike #2
shape) + n0 relay default + self-host knob + disclosure (REQ-NET-2) + mDNS LAN
discovery. Acceptance: two local nodes discover + connect. Then D2 pairing (register
the 3 new REQ-HAZARD-PAIR-* in traceable-reqs.toml FIRST, rule 3). Each D-task is
milestone-sized — expect /self-clear + commune between most.

Not pushed yet (2 local commits ahead of a14639a). CI gotchas in force: spt_home()
writes must create_dir_all the parent; never name a bin/test/staged-update artifact
*update*/*setup*/*install*/*patch* on Windows (UAC os error 740) — see

**M3 COMPLETE + CI-green (2026-06-03).** M3a + M3b + M3c shipped on `dev-freeform`
(M3c = fe0acce→a14639a, CI run 26901923120). Full ADR-0004 architecture live.

**M4 (`spt-net`) STARTED 2026-06-03** (user gave explicit go). Done so far on
`dev-freeform`:
- **Plan expanded** (commit ca6522b): `M4-PLAN.md` Tasks now a full D0–D9
  breakdown with sub-tasks, requirement→task map, and a binding red-team
  obligations table (pairing #10 seed-rotation / #11 rate-limit / #12 transcript;
  instances #7 merge-clock / #8 epoch-lease / #9 dormant-budget; #6 failure-domain).
- **D0 scaffold** (commit c47d2c6): `crates/spt-net` created, wired into workspace,
  whole transport behind default-on `net` feature (ADR-0002). check green (default
  + `--no-default-features`), layering acyclic, `traceable-reqs check` green. No REQ
  activated yet (rule 5 — scaffold delivers none; REQ-NET-1 lands at D1).

**NEXT = D1** — Iroh endpoint (reuse spt-proto Ed25519 identity, iroh 0.98 / Spike #2
shape) + n0 relay default + self-host knob + disclosure (REQ-NET-2) + mDNS LAN
discovery. Acceptance: two local nodes discover + connect. Then D2 pairing (register
the 3 new REQ-HAZARD-PAIR-* in traceable-reqs.toml FIRST, rule 3). Each D-task is
milestone-sized — expect /self-clear + commune between most.

Not pushed yet (2 local commits ahead of a14639a). CI gotchas in force: spt_home()
writes must create_dir_all the parent; never name a bin/test/staged-update artifact

The file C:\Users\decid\.claude\projects\C--Users-decid-Documents-projects-spt-core\memory\MEMORY.md has been updated successfully. (file state is current in your context — no need to Read it back)

# Memory index

- [Cross-machine test rig](cross-machine-test-rig.md) — enlyzeam (Windows, ssh key) for two-host network spikes + Tailscale-down gotcha; gravity-linux (Ubuntu, david/bigscreen pw-auth + askpass shim) as the Linux/forkpty build host.
- [CI traceability gate](ci-traceability-gate.md) — how CI installs traceable-reqs (TRACEABLE_REQS_TOKEN PAT + latest BigscreenVR release); the v0.1.0-stale-binary gotcha + the v0.1.1 fix; I have admin to cut releases.
- [Attractor build harness](attractor-build-harness.md) — attractor+pi/codex setup at ../attractor; codex model = openai-codex/gpt-5.5 (NOT the SPEC's gpt-5.3-codex); viable for bounded single-machine spt-core tasks (SPIKE-07b gix pilot).
- [Windows UAC binary-name 740](windows-uac-binary-name-740.md) — exe names containing update/setup/install/patch trigger UAC elevation (os error 740); name self-update artifacts + test bins to dodge it.
- [M4 resume state](m4-resume-state.md) — M4 (spt-net) STARTED 2026-06-03; plan expanded + D0 scaffold done (commits ca6522b/c47d2c6), next = D1 Iroh endpoint.

+- [M4 resume state](m4-resume-state.md) — M4 (spt-net) in progress 2026-06-03; D0+D1 done (iroh =0.98.2 endpoint, identity-bound, relay policy, mDNS); spt-net = first async crate; next = D2 pairing.


D1 complete — committed `3f726ed` + `51981c4`. Both calls made: **iroh pinned `=0.98.2`** (Spike #2-proven, incl. cross-NAT hole-punch); **merge-model #7 decided** (per-node epoch + version-vector, concurrent=explicit conflict; unifies with #8 — `c49e522`).

**D1 shipped:**
- `NetEndpoint` over iroh 0.98.2, keyed by the node's **own** spt-proto Ed25519 seed → **iroh EndpointId == node pubkey** (address *is* the name, no second identity). ALPN `spt-core/net/0`.
- `RelayPolicy {N0Default | SelfHosted(RelayMap) | Disabled}` + `RELAY_DISCLOSURE` — ADR-0002 relay stance (REQ-NET-2).
- `LocalDiscovery {Mdns | Off}` + `connect_by_id` — LAN discovery, dial-by-id-only.
- `NetEndpoint::iroh()` = the D4 broker-ownership seam.

**Verified:**
| Test | Where | Result |
|---|---|---|
| identity-binding equality | CI (hermetic) | ✅ |
| loopback QUIC bidi echo | CI (hermetic) | ✅ |
| mDNS discover + connect-by-id | local (`#[ignore]`, CI multicast unreliable) | ✅ 3.1s |

`--no-default-features` clean, REQ-NET-1 `[impl,unit]` + REQ-NET-2 `[impl]`, `traceable-reqs check` green.

**Notable:** spt-net is the workspace's **first async crate** (iroh+tokio, `net`-gated) — rest is sync/thread-based. D4 broker must host the tokio runtime.

5 commits ahead of `a14639a`, unpushed.

**Next = D2 pairing** (TOTP-SPAKE2, security-critical: transcript binding #12, seed rotation #10, rate-limit #11; register 3 hazard reqs first). It's milestone-sized + crypto-heavy, and my context is now heavy with iroh research. Recommend `/self-clear` before D2 for a clean slate — memory + plan are updated to resume cleanly.

Want me to **self-clear and continue to D2**, or **push these 5 commits first** / hold for your input on the SPAKE2 crate choice?


surely psyche invocations are thread-based (or external process launches?) and just not implemented yet? because if each psyche or echo commune launch is synchronous, it will prevent all other agents' psyches and echo communes from running on their independent schedules, until the launched one finishes. please confirm.


<owl_reachability_notice>
You have an active owl perch. When spawning subagents or doing work, use run_in_background: true so you stay reachable for incoming messages.
</owl_reachability_notice>


CAVEMAN MODE ACTIVE (full). Drop articles/filler/pleasantries/hedging. Fragments OK. Code/commits/security: write normal.


Good catch — "sync" (no tokio) ≠ "blocking". Different things. Let me verify how Psyche/commune actually launch rather than speculate.

`spawn_psyche` → `runtime.spawn_session` returning an OS pid (separate process); echo-commune spawns a child with a timeout. Need to confirm: detached vs waited, and whether pulse loops are per-agent threads. Reading the spawn primitive + echo body + daemon pulse-hosting.

Clearer now: **Psyche spawn = detached process** (fire-and-forget, pid recorded — non-blocking). **Echo commune = bounded process**: `run_bounded_stdin` spawns the cheap-model child and the caller thread *waits* (with timeout). So echo IS synchronous on its calling thread. The real question = is each agent's pulse loop its own thread? Confirming where `run_pulse_loop` is spawned.

Decisive context: ADR-0004 — "**the daemon is the single brain for a machine** ... and **psyche loops** [plural] together." One daemon hosts N per-agent pulse loops. `run_pulse_loop` is per-agent + killable, but only referenced in its def+test — so the multi-agent thread fan-out may not be wired yet. Confirming whether anything spawns it in production.
