12	2. **Tag in the same change as the evidence.** When you write the function / test / doc-section that satisfies a stage, add its `[stage->REQ-ID]` tag in *that same commit*. Never "tag later" — this single rule is what stops the trace from drifting.

14	4. **KNOWN-HAZARDS are first-class requirements.** Each invariant is a `REQ-HAZARD-*` requiring `unit` (and `int` where cross-process/cross-node). A hazard cannot be "covered" without a test tagging it — the anti-regression promise becomes mechanical (PRD success criterion #6).
15	5. **Activation, not premature failure.** Every requirement starts `required_stages = []` (inactive) so `check` stays green pre-code.

Two parse errors are prose placeholders `[stage->REQ-ID]` (lines 12, 41) — the scanner reads them as malformed tags. Pre-existing, surfaced now that roots exist. Fix: break the tag-shape with angle brackets so they read as placeholders, not tags.


Edit

When you write the function / test / doc-section that satisfies a stage, add its `[stage->REQ-ID]` tag in *that same commit*.

When you write the function / test / doc-section that satisfies a stage, add its `[<stage>-><REQ-ID>]` tag in *that same commit*.

## Stage A + Spike #1 — done

**Spike #1 (Windows ConPTY, hardest path): PASS.** Broker-owns-handles model validated — child + live client socket survive brain restart, input still routes post-restart. ADR-0004's split survives red-team. Discovered + fixed a real gotcha (ConPTY DSR stall) that would've bitten the terminal layer.

**Findings folded into the corpus:**

| File | Change |
|---|---|
| `docs/reviews/STAGE-A-codex-redteam.md` | 14 findings (5 FATAL, 9 SERIOUS), full dispositions |
| `docs/spikes/SPIKE-01-broker-handoff.md` | spike record, result, 4 open gaps for M3 |
| `docs/adr/0004` | update-class taxonomy, **ownership table**, DSR req, open gaps (resolves 4 FATAL) |
| `docs/adr/0005` | seed epoch+rotation (real revocation), subnet-global rate-limit, transcript binding |
| `docs/adr/0003` | epochs/vector-clocks over wall-clock, registry lease, dormant-warm budget |
| `docs/adr/0002` | fault-injection matrix, broker-kernel-size tradeoff |
| `docs/KNOWN-HAZARDS.md` | +3 hazards: 5.5 ConPTY-DSR, 7.1 api-auth, 7.2 idempotent-delivery |
| `traceable-reqs.toml` | +4 `REQ-HAZARD-*` (inactive) |
| `docs/TRACEABILITY.md` | fixed 2 latent parse errors (placeholder tags) |
| `src/`, `tests/` | `.gitkeep` placeholders so the gate runs pre-code |

**Throwaway spike code** lives in sibling `../spt-spikes/spike-01-broker-handoff` — not in spt-core.

**Open decisions left for you** (not mine to lock): merge model for #7 (vector-clock vs CRDT), seed-rotation protocol shape (#10), and whether to reword locked PRD **R-UPD-3** to scope the no-terminate guarantee to brain-only (ADR-0004 §A flags it).

Next options:
1. **Commit** this Stage-A batch (didn't auto-commit — your call per repo rules).
2. **Spike #2** — Iroh+mDNS smoke test (the other design-threatening unknown; also closes spike-gap #1: live QUIC stream survival).
3. **`plan-eng-review`** — second half of Stage A (interactive architecture pass).

docs: Stage A red-team + Spike #1 (broker/brain handoff validated)

Stage A of the roadmap (red-team before building). Codex adversarial pass
on PRD + 5 ADRs + KNOWN-HAZARDS surfaced 14 findings (5 FATAL, 9 SERIOUS),
all clustered on ADR-0004 (broker/brain no-terminate handoff) + ADR-0005
(pairing revocation). Spike #1 then tested the hardest path empirically.

Spike #1 (Windows ConPTY) PASS: broker owning the sole PTY reader+writer +
child + accepted client sockets lets the brain (logic) die and restart with
no child termination, no client-stream gap, and input still routed after
restart. Validates ADR-0004's split on the high-risk OS path. Throwaway code
lives outside the repo (../spt-spikes/spike-01-broker-handoff).

New hazard discovered by the spike: ConPTY withholds all child output until
the terminal answers its DSR cursor query (ESC[6n -> ESC[1;1R).

Folded findings back into the corpus (roadmap step 3):
- docs/reviews/STAGE-A-codex-redteam.md: all 14 findings + dispositions
- docs/spikes/SPIKE-01-broker-handoff.md: method, result, 4 open gaps for M3
- ADR-0004: update-class taxonomy, normative ownership table, DSR req, gaps
- ADR-0005: seed epoch+rotation (real revocation), subnet-global rate-limit,
  full pairing-transcript binding
- ADR-0003: monotonic epochs over wall-clock (resolution + context merge),
  dormant-warm resource/security budget
- ADR-0002: single-failure-domain fault-injection matrix; broker-size tradeoff
- KNOWN-HAZARDS: +5.5 ConPTY-DSR, +7.1 local api-auth, +7.2 idempotent delivery
- traceable-reqs.toml: +4 REQ-HAZARD-* (inactive until milestone activation)
- TRACEABILITY.md: fix 2 latent placeholder-tag parse errors
- src/, tests/: .gitkeep so the traceability gate runs pre-code

traceable-reqs check: green (95 reqs OK, 0 findings).

Open decisions deferred to the user: merge model for concurrent context
(vector-clock vs CRDT), seed-rotation protocol shape, and whether to reword
locked PRD R-UPD-3 to scope the no-terminate guarantee to brain-only updates.

Question: select:WebFetch,WebSearch


WebFetch

Prompt: Give the exact current API for iroh 0.98. I need: (1) how to build and bind an Endpoint with the n0 discovery and a custom ALPN; (2) how to get this endpoint's own NodeAddr or NodeId for sharing; (3) the accept side: how to accept an incoming connection and open/accept a bidirectional stream; (4) the connect side: how to connect to a NodeAddr/NodeId with an ALPN and open a bidi stream; (5) send/recv bytes on the bi streams and finish. Quote the exact method names and signatures (e.g. bind(), accept(), connect(), open_bi(), accept_bi(), node_addr(), node_id(), online()/home_relay()). Note anything that returns a Watcher vs a direct value.


# Iroh 0.98.2 API Summary

## (1) Build and Bind Endpoint with N0 Discovery and Custom ALPN

```rust
let endpoint = Endpoint::builder(presets::N0)
    .alpns(vec![b"my-alpn".to_vec()])
    .bind()
    .await?;
```

Key methods:
- `Endpoint::builder(preset)` → `Builder`
- `Builder::alpns(Vec<Vec<u8>>)` → `Builder`
- `Builder::bind()` → `Future<Result<Endpoint, BindError>>`

## (2) Get Endpoint's Own Address for Sharing

```rust
let endpoint_id = endpoint.id();  // EndpointId
let endpoint_addr = endpoint.addr();  // EndpointAddr
```

Methods:
- `Endpoint::id()` → `EndpointId` (direct value)
- `Endpoint::addr()` → `EndpointAddr` (direct value, contains relay + addresses)
- `Endpoint::watch_addr()` → `impl Watcher<Value = EndpointAddr>` (monitored value)

For internet dialability, call `endpoint.online().await` first to ensure "at least one relay server has completed its connection handshake."

## (3) Accept Side: Incoming Connection and BiStream

```rust
while let Some(incoming) = endpoint.accept().await {
    let alpn = incoming.alpn();
    let conn = incoming.accept().await?;

    // Accept bidirectional stream
    if let Some((mut send, mut recv)) = conn.accept_bi().await? {
        // Use send/recv...
    }
}
```

Methods:
- `Endpoint::accept()` → `Accept<'_>` (future yielding `Option<Incoming>`)
- `Incoming::accept()` → `Future<Result<Connection, ...>>`
- `Connection::accept_bi()` → `Future<Result<Option<(SendStream, RecvStream)>, ...>>`

## (4) Connect Side: Dial Remote and Open BiStream

```rust
let conn = endpoint.connect(endpoint_addr, b"my-alpn").await?;
let (mut send, mut recv) = conn.open_bi().await?;
```

Methods:
- `Endpoint::connect(EndpointAddr | EndpointId, &[u8])` → `Future<Result<Connection, ConnectError>>`
- `Connection::open_bi()` → `Future<Result<(SendStream, RecvStream), ...>>`

Alternative with more control:
- `Endpoint::connect_with_opts(...)` → `Future<Result<Connecting, ...>>`
- `Connecting::into_0rtt()` or await to get `Connection`

## (5) Send/Recv Bytes and Finish

The documentation shows `SendStream` and `RecvStream` but doesn't detail their exact method signatures here. Typically:
- `SendStream` implements write operations
- `RecvStream` implements read operations
- Both support `.finish()` / `.stop()` and standard async I/O

**Note:** No `node_addr()`, `node_id()`, or `home_relay()` methods are documented in this API surface—use `id()` and `addr()` instead.


iroh 0.98 API captured (`Endpoint::builder(presets::N0)`, `.addr()`/`.id()`, `accept_bi`/`open_bi`). Smoke scope: two in-process endpoints connect + echo round-trip + report setup time + binary size. (Live-QUIC-stream-survival-across-restart = bigger integration spike; noting as deferred, not forcing into smoke.) Writing.

Monitor needs its schema loaded — not worth it; the background task auto-notifies on completion. Quick interim check, then I wait for the notification.


Build still running (output buffered until tail flushes at end). I'll wait for the completion notification rather than poll.


ScheduleWakeup

Fallback heartbeat while the large iroh dependency tree compiles; completion notification is the primary wake.

Prompt: Continue Spike #2: check the iroh smoke-test build result and proceed.


Next wakeup scheduled for 20:18:00 (in 110s). Nothing more to do this turn — the harness re-invokes you when the wakeup fires or a task-notification arrives.


Build compiling (iroh pulls a large tree). Will resume when the build notification fires.

Two real API deltas: `accept_bi()` returns the tuple directly (not `Option`), and `conn_type` doesn't exist on `Endpoint` in 0.98. Fix both — drop the path-classification probe (can't NAT-test on one host anyway).

# Spike #2 — Iroh smoke test

> Date: 2026-05-31. Status: **PASS (smoke scope)** — networking premise not falsified; the real cross-NAT proof is deferred to M4 (needs two machines).
> Throwaway code: `../spt-spikes/spike-02-iroh-smoke` (outside the spt-core repo).
> Drives ROADMAP Stage B Spike #2 + validates ADR-0002 (bake Iroh into the core).

## Question

ADR-0002 makes WAN networking first-class day-one on Iroh. Before committing the whole `spt-net` crate to it: **does Iroh's current API actually give us a clean QUIC connect + bidirectional message exchange, and what footprint does it add?**

## Method

iroh `0.98.2`, tokio. One process, two endpoints (`server`, `client`), each built with the N0 preset + a custom ALPN (`spt-spike/iroh-smoke/0`). Server accepts a connection, accepts a bidi stream, echoes the request. Client connects by `EndpointAddr`, opens a bidi stream, sends `ping`, reads the response. Assert `echo:ping`.

API shape that worked (0.98 — churns every release, pin this):
- `Endpoint::builder(iroh::endpoint::presets::N0).alpns(vec![ALPN.to_vec()]).bind().await`
- own identity: `ep.id()` → `EndpointId`, `ep.addr()` → `EndpointAddr` (direct values, not watchers)
- accept: `incoming.accept()?.await?` → `Connection`; `conn.accept_bi().await?` → `(SendStream, RecvStream)` **directly** (not `Option`)
- connect: `ep.connect(addr, ALPN).await?`; `conn.open_bi().await?`
- streams: `send.write_all(&b).await?; send.finish()?;` · `recv.read_to_end(max).await?`
- `Endpoint::conn_type()` does **not** exist in 0.98 — path classification needs another route.

## Result

```
response       : "echo:ping"
connect time   : 14 ms
total setup    : 99 ms   (two endpoint binds + N0 discovery init + handshake)
binary size    : debug 26.68 MB | release 13.57 MB (optimized, unstripped)
round-trip echo over Iroh QUIC : PASS  →  OVERALL PASS ✅
```

The API is workable and terse; handshake on a single host is sub-15ms. Footprint: **13.57 MB release** vs the research brief's ~8MB estimate — the gap is LTO/`strip`/`opt-level="z"`/`panic="abort"`, none applied here. ~8MB is plausible for the shipped binary with size profile tuning; budget for it.

## What this does NOT prove (the real risks, deferred to their milestones)

1. **Cross-NAT path + direct-vs-relay** — single-host run, so NAT traversal, hole-punching, and n0-relay fallback are **untested**. This is the actual "networking works" proof and the roadmap's M4 real-proof gate; it needs two machines on separate networks. **Highest remaining networking risk.**
2. **mDNS LAN discovery** — not exercised (one host). The N0 preset wires n0-relay discovery; local mDNS discovery is a separate path to smoke on a real LAN.
3. **Live QUIC stream survival across a brain restart** (Spike #1 open-gap #1, codex FATAL #2) — needs the ADR-0004 broker owning the Iroh endpoint while the brain cycles. Integration spike, not smoke.

## Verdict

Iroh `0.98` is a sound foundation for `spt-net`: clean connect/echo, fast local handshake, acceptable footprint. ADR-0002 stands. Promote the cross-NAT/relay measurement and the broker-owned-stream-survival test into M4 planning rather than re-litigating the choice now.

Spike #2 recorded. Update ROADMAP to reflect Stage A + spike progress.


Edit

## Immediate next steps (next session)

1. **Stage A review** — run `plan-eng-review` on the architecture + a `codex` adversarial pass; capture findings.
2. **Spike #1 (broker/brain handoff)** and **#2 (Iroh smoke test)** — the two that most threaten the design. Throwaway repos/branches.
3. Fold review findings + spike results back into the ADRs/CONTEXT (amend if anything breaks).
4. Then start **M0** (workspace + `spt-proto` + `spt-store`).

## Immediate next steps

Progress (2026-05-31):
- ✅ **Stage A — codex adversarial pass** — done. 14 findings (5 FATAL, 9 SERIOUS) in `docs/reviews/STAGE-A-codex-redteam.md`.
- ✅ **Spike #1 (broker/brain handoff)** — PASS on Windows ConPTY. `docs/spikes/SPIKE-01-broker-handoff.md`. Found+fixed the ConPTY DSR-stall hazard. 4 open gaps carried to M3.
- ✅ **Spike #2 (Iroh smoke test)** — PASS (single-host). `docs/spikes/SPIKE-02-iroh-smoke.md`. iroh 0.98 API workable; 13.57 MB release. Cross-NAT/relay proof deferred to M4.
- ✅ **Findings folded** into ADR-0002/0003/0004/0005 + KNOWN-HAZARDS (+3) + traceable-reqs.toml (+4 REQ-HAZARD).

Remaining before M0:
1. **Stage A — `plan-eng-review`** (interactive architecture pass; second half of Stage A).
2. **Spike #4 (manifest-driven lifecycle)** — a manifest drives one real session spawn→bind→commune→signoff. (Spike #3 ConPTY hosting is largely covered by Spike #1.)
3. Resolve the open user decisions logged in the ADR amendments (context-merge model, seed-rotation, R-UPD-3 rewording).
4. Then start **M0** (workspace + `spt-proto` + `spt-store`).

# spt-core Roadmap

> Lightweight-but-structured path from design → fruition. Not a GSD/phase-gated process — a clear sequence with de-risk gates. Planning corpus is complete (PRD + CONTEXT + 5 ADRs + 6 design docs); this is how we build it.

## End goal

A harness-independent core for an agent ecosystem — messaging, live-agent lifecycle, terminal hosting, **first-class P2P networking**, and a runtime-manifest harness contract — shipped as Rust crates + a single `spt` binary. The proof: the same agent runs natively across all of a user's machines with a synced mind, reachable and operable from anywhere, with seamless self-update and zero-config cross-machine messaging. First thing built atop it: a rebuilt `spt` plugin at parity with today's modern SPT.

## Scope decisions (locked)

- **v1 = the full PRD, networking included.** The networked element is the *reason* spt-core exists; it is not deferrable to v1.1.
- **The hard freeze on `claude_skill_owl` is not a clock.** It works today and delivers value as-is while spt-core is built — no schedule pressure from it.
- **Process: lightweight but structured.** GSD is too heavy. This roadmap + the design docs are the structure.

## Path to fruition (sequence)

**Stage A — Red-team review (before building).** Pressure-test the design adversarially. Focus on the riskiest architectural decisions, not bikeshedding. Tools: `plan-eng-review` (architecture) + `codex` (adversarial second opinion). Scope-cutting is *not* a goal (v1 is locked as full PRD), but surfacing contradictions / over-engineering / unproven assumptions is.

**Stage B — De-risk spikes.** Throwaway proofs of the load-bearing unknowns — anything that, if it fails, forces a redesign. Do these before committing to the full build. See *De-risk spikes* below.

**Stage C — Walking skeleton.** Build the killer-quickstart slice end-to-end through the real crate boundaries: **two agents exchange a message** (first local; ultimately cross-node — the real proof). Validates the whole stack early; then thicken.

**Stage D — Phased build (M0–M5).** Dependency-ordered, each milestone ships something usable.

## Milestones (all v1)

- **M0 — Workspace + commodity layer.** Cargo workspace; `spt-proto` (wire envelope grammar, endpoint types, framing, Ed25519 identity, typed+binary payloads) + `spt-store` (spool, perch layout, trust store, registry persistence). Copy-verbatim the stable formats from the sister project (ADR-0001).
- **M1 — Local messaging + binary.** `spt-msg` (delivery TCP+spool, routing, send/ring/ready) + the `spt` binary + CLI. **= the killer quickstart (local): two agents exchange a message.**
- **M2 — Harness contract + lifecycle.** `spt-runtime` (AgentRuntime, ManifestRuntime, manifest schema) + `spt-live` (Psyche/pulse/commune/signoff) + the `api` subcommand surface + both startup topologies. **Rebuild the `spt` plugin to parity** (the stated first sub-project).
- **M3 — Terminal wrapper + daemon + self-update.** `spt-term` (session-surface, PTY, broker) + the consolidated `spt-daemon` (broker/brain split) + peer-propagated signed self-update.
- **M4 — Networking + instances.** `spt-net` (Iroh WAN, mDNS LAN, TOTP-SPAKE2 pairing, subnet registry) + the multi-instance model + cross-node Psyche sync (P2P, opt-in GitHub hub). **= the real proof: cross-node message + drive an agent on machine A from machine B.**
- **M5 — Shells, presence, deferred capabilities.** Shell adapters + sleep/wake, PresenceChannel, and the consent-gated capabilities (remote-exec, instantiate-anywhere) landing into the v1 consent seam.

## De-risk spikes (do early — these can invalidate the architecture)

1. **Broker/brain no-terminate handoff** — prove a PTY child + open socket survive a daemon-*logic* restart (FD-passing or stable-broker shim). The hardest invariant in the design (ADR-0004).
2. **Iroh + mDNS smoke test** — two nodes, separate NATs, one message end-to-end; measure direct-vs-relay + binary size (research brief §5). Validates the whole networking premise.
3. **ConPTY + `portable-pty`** — host and drive a real session in a broker PTY on Windows + Linux.
4. **Manifest-driven lifecycle** — a manifest drives one real Claude Code session through spawn → bind → commune → signoff, proving harness-independence works in practice.

## Immediate next steps (next session)

1. **Stage A review** — run `plan-eng-review` on the architecture + a `codex` adversarial pass; capture findings.
2. **Spike #1 (broker/brain handoff)** and **#2 (Iroh smoke test)** — the two that most threaten the design. Throwaway repos/branches.
3. Fold review findings + spike results back into the ADRs/CONTEXT (amend if anything breaks).
4. Then start **M0** (workspace + `spt-proto` + `spt-store`).

## Tooling: requirement traceability (adopted)

`traceable-reqs` is adopted as the requirement-tracing gate. `traceable-reqs.toml` seeds the `REQ-*` registry from PRD `R-*` + KNOWN-HAZARDS invariants (all inactive until milestone activation). The development contract + enforcement (CI gate, milestone activation, agent rule, quality audit) is `docs/TRACEABILITY.md`; the agent rule lives in `CLAUDE.md`. **M0 task:** install the CLI, validate the seed, wire the CI workflow, activate M0 reqs.

## Open threads carried forward

- New deferred items logged this session (`docs/DEFERRED.md`): block-level OCC context merge; the rebalance / Memory-Health pass; the consent framework's gated capabilities.
- The dual-audience docs strategy (`docs/DOCS-STRATEGY.md`) governs the *shipped* docs, authored as code lands.

-1. **Stage A review** — run `plan-eng-review` on the architecture + a `codex` adversarial pass; capture findings.

-2. **Spike #1 (broker/brain handoff)** and **#2 (Iroh smoke test)** — the two that most threaten the design. Throwaway repos/branches.

-3. Fold review findings + spike results back into the ADRs/CONTEXT (amend if anything breaks).

+- ✅ **Stage A — codex adversarial pass** — done. 14 findings (5 FATAL, 9 SERIOUS) in `docs/reviews/STAGE-A-codex-redteam.md`.

Commit Spike #2 record + roadmap progress.


Bash

cd "C:/Users/decid/Documents/projects/spt-core" && git add -A && git commit -F - <<'EOF'
docs: Spike #2 (Iroh smoke test) PASS + roadmap progress

Spike #2 validates the networking premise (ADR-0002). Two iroh 0.98 endpoints
establish a QUIC connection with a custom ALPN and complete a bidi echo
round-trip; connect 14ms, total setup 99ms on a single host. Release binary
13.57 MB (vs the ~8MB research-brief estimate, reachable with LTO/strip/opt-z).

Smoke scope only: single-host, so cross-NAT traversal + direct-vs-relay path +
mDNS LAN discovery are NOT tested — those are the M4 real-proof gate (need two
machines). Live QUIC stream survival across a brain restart stays an M3/M4
integration spike. Iroh API surface for 0.98 captured in the doc (it churns).

- docs/spikes/SPIKE-02-iroh-smoke.md: method, result, deferred risks, API notes
- ROADMAP.md: Stage-A codex + Spike #1 + Spike #2 marked done; remaining =
  plan-eng-review, Spike #4 (manifest lifecycle), open ADR decisions, then M0

Throwaway code lives outside the repo (../spt-spikes/spike-02-iroh-smoke).

Committed `dbb21e4`. Both recommended steps done.

## Stage B spikes complete — both green

| | Result | Key output |
|---|---|---|
| **Spike #1** broker/brain handoff | ✅ PASS (Win ConPTY) | ADR-0004 split survives; found+fixed DSR-stall hazard |
| **Spike #2** Iroh smoke | ✅ PASS (single-host) | iroh 0.98 workable, 13.57MB release, 14ms connect |

Three commits on `main`: `94ff79d` (Stage A + Spike #1), `dbb21e4` (Spike #2). Tree clean, gate green.

**Neither spike falsified the architecture.** The two design-threatening unknowns held. Real risks now *scoped and scheduled* rather than unknown:
- live QUIC stream survival across brain restart → M3 integration spike
- cross-NAT + direct-vs-relay → M4 (needs a 2nd machine)

**Not pushed** — 2 new commits local on `main` (`origin/main` exists from the sync setup). Say the word to push.

---

Roadmap remaining before M0:
1. **`plan-eng-review`** — second half of Stage A (interactive architecture pass). The one review tool not yet run.
2. **Spike #4** — manifest-driven lifecycle (spawn→bind→commune→signoff through a real session).
3. **Open decisions** you own — context-merge model (vector-clock vs CRDT), seed-rotation protocol, R-UPD-3 rewording.
4. **M0** — cargo workspace + `spt-proto` + `spt-store`.

Recommend: **push**, then **`plan-eng-review`** to close Stage A before any building. Then the open decisions (3) gate cleanly into M0. Want me to push + start the eng-review?

Also — Psyche sync is live now; I can drop a `/spt:commune` to checkpoint this Stage-A milestone cross-machine. Say if you want that.


there's another machine on the vpn, 'enlyzeam' (resolvable IP via vpn DNS), that we can use to smoke test iroh. shall we try it?


Yes — worth it. Caveat up front: two machines on the same VPN = flat routable subnet, so this proves **real cross-machine connect + direct path + message exchange**, but NOT hostile-NAT hole-punching (VPN bypasses that). Still closes Spike #2's biggest gap.

Blocker to sort first: how do we execute on enlyzeam? Checking what's reachable.


echo "=== owl agents ==="; $OWL list 2>&1 | head -30; echo "=== resolve enlyzeam ==="; ping -n 1 enlyzeam 2>&1 | head -4; echo "=== ssh? ==="; (ssh -V 2>&1 | head -1); (command -v ssh >/dev/null && echo "ssh present" || echo "no ssh")

enlyzeam = Tailscale (`100.125.242.88`, 30ms, reachable). No owl agent there — both listed agents are local. ssh present here. Probe whether I can drive enlyzeam non-interactively (BatchMode fails fast if no key, won't hang).


ssh -o BatchMode=yes -o ConnectTimeout=6 enlyzeam "echo SSH_OK; uname -a 2>/dev/null || ver" 2>&1 | head -6; echo "---tailscale ssh?---"; (command -v tailscale >/dev/null && tailscale status 2>&1 | head -8 || echo "no tailscale CLI on PATH")

Probe non-interactive ssh to enlyzeam and tailscale status

Both Windows, both on Tailscale — enlyzeam has a **direct** path. SSH just needs the host key accepted. Retry with `accept-new` (Tailscale SSH should auth as brandon@ without a password).


ssh -o StrictHostKeyChecking=accept-new -o BatchMode=yes -o ConnectTimeout=8 enlyzeam "echo SSH_OK & ver" 2>&1 | head -8

SSH to enlyzeam accepting new host key


Warning: Permanently added 'enlyzeam' (ED25519) to the list of known hosts.
decid@enlyzeam: Permission denied (publickey,password,keyboard-interactive).


OpenSSH needs a key/password I don't have. Try Tailscale-native SSH (auths via tailscale identity).


tailscale ssh -o BatchMode=yes enlyzeam "ver" 2>&1 | head -8; echo "exit ${PIPESTATUS[0]}"

Try tailscale ssh to enlyzeam


flag provided but not defined: -o
SSH to a Tailscale machine

USAGE
  tailscale ssh [user@]<host> [args...]

The 'tailscale ssh' command is an optional wrapper around the system 'ssh'
command that's useful in some cases. Tailscale SSH does not require its use;
exit 2


timeout 12 tailscale ssh enlyzeam "ver" 2>&1 | head -10; echo "exit ${PIPESTATUS[0]}"

Try tailscale ssh wrapper to enlyzeam


No ED25519 host key is known for enlyzeam.gazella-geological.ts.net. and you have requested strict checking.
Host key verification failed.

Can't non-interactively auth into enlyzeam — `decid@enlyzeam: Permission denied (publickey,password)`; Tailscale SSH server isn't enabled there either. So **I can't drive enlyzeam myself** — you'll run the server side.

Two things needed: (1) make the spike cross-machine (server/client subcommands + a shareable address ticket), (2) decide how the server runs on enlyzeam. Prepping (1) now. Checking iroh 0.98's ticket/serialization API.


WebFetch

Prompt: How do I serialize an endpoint's address into a shareable string on one machine and parse it back on another to connect? Is there a ticket type (NodeTicket / EndpointTicket) in iroh 0.98 or iroh-base? Does EndpointAddr implement serde Serialize/Deserialize? What is the exact type name and module path for EndpointAddr and any ticket type, and the methods/From impls to convert EndpointAddr <-> ticket <-> string (Display/FromStr)? Show the minimal code to print a connectable address string from an Endpoint and to connect using a parsed one.


Based on the documentation provided, I can see that `EndpointAddr` exists as a struct in iroh 0.98.2, defined as: "Network-level addressing information for an iroh endpoint."

However, the webpage content does not contain the specific implementation details you're asking about, including:

- Whether `EndpointAddr` implements `serde` traits
- The existence of ticket types (NodeTicket/EndpointTicket)
- The exact serialization/deserialization methods
- Display/FromStr implementations
- Code examples showing string conversion workflows

To find this information, you would need to:

1. Visit the full API documentation at docs.rs for iroh 0.98.2
2. Check the iroh-base crate documentation (referenced as a dependency)
3. Examine the GitHub repository at https://github.com/n0-computer/iroh
4. Review the examples directory mentioned in the documentation

The landing page shown doesn't provide the implementation-level details required to answer your question about serialization patterns and exact type signatures.


Prompt: List the trait implementations for EndpointAddr. Specifically: does it implement serde Serialize and Deserialize? Does it implement Display and FromStr? What are its public fields (endpoint id, relay url, direct addresses)? How is it constructed - is there a constructor like EndpointAddr::new(id) or from_parts, and methods to add direct socket addresses or a relay url? I want to build an EndpointAddr on machine B from an endpoint id string plus a socket address. Quote exact field names, method signatures, and constructors.
