Write SPT_TWO_HOST=1 gated int tests (D9b ladder)

tests gated on SPT_TWO_HOST=1 + role/peer-addr env, silent skip otherwise. Ladder: pair → register → cross-node message → remote-drive → Psyche sync → update self-heal + notif cross-node leg (insert A→fires B; dismiss B→replicates A). Int tags [int->REQ-NET-1], [int->REQ-INST-5], [int->REQ-UPD-1], [int->REQ-NOTIF-1] + pairing/registry as touched. Stages NOT activated until rig run green.

Write docs/TWO-HOST-RUNBOOK.md

Exact rig procedure HFENDULEAM ↔ gravity-linux: env setup, run order, what green looks like. Evidence appendix filled after real run. Consider [twohost] commit-message CI gate for gravity leg (no SSH from HFENDULEAM).

Run two-host proof on rig, capture evidence

Execute runbook on HFENDULEAM + gravity (likely via [twohost] CI gate for gravity leg). Capture run output into runbook appendix. Then activate int stages on touched reqs in traceable-reqs.toml. Flake-ledger discipline for any rig flake.

Retire gh-repo interim sync (CONTEXT.md note)

After proof green: note in CONTEXT.md — sister gh-repo-sync skill stands down; psyche-sync-setup remains for hub-mode seam but no longer THE sync path.

feat(net,daemon,ci,docs): M4-D9-6-1 two-host rig ladder — env-gated int tests + runbook

The M4-PLAN §D9b ladder as SPT_TWO_HOST=1-gated tests (silent skip
otherwise): pair (real cross-host SPAKE2/TOTP) -> register -> WAN message
-> remote-drive (fetch + attach echo + push) -> Psyche sync both directions
-> update self-heal under the verify gate (consent-notified, REQ-UPD-4
posture) -> notif insert-fires/dismiss-replicates. All identities and
addresses derive from a shared secret + static env, so both legs run
non-interactively; the [twohost] commit-message CI gate runs role A on
hfenduleam and role B on gravity in one tagged push (needs: test releases
them together). BindScope::Port gives a node a fixed dialable UDP port
(static ip:port tickets, no relay/discovery). Full ladder proven green
locally as two processes over 127.0.0.1; int stages activate only after
the real rig run (TRACEABILITY rule: evidence first).

Slice D9-6-1 pushed (107240e), CI in progress. State:

**Done**
- `twohost.rs` — full §D9b ladder, env-gated, both roles. **Proven green locally** (two processes, 127.0.0.1): pair (real SPAKE2) → register → message → remote-drive → sync×2 → update+consent → notif dismiss-replication. Smoke caught + fixed one real bug (test op-ids colliding with pump's journaled ops).
- `BindScope::Port` — fixed-port production bind for static ip:port tickets.
- `docs/TWO-HOST-RUNBOOK.md` — rig procedure, tailscale addressing (HFENDULEAM `100.68.35.65` ↔ gravity `100.100.62.43`, 23ms), evidence appendix pending.
- CI `[twohost]` gate — both rig hosts are the runners; `needs: test` releases roles together.

**Next** (on CI green): empty `[twohost]` commit → rig proof → evidence appendix + int-stage activation (9 reqs ready) + gh-interim retirement note.

**Notes**: no SSH to gravity (key auth denied, tailscale-ssh not enabled — CI gate stays the drive path). Firewall rule needs elevation I lack; stateful UDP 4-tuple reuse should suffice, rig run will tell.

(M4-D9-6 proof run). docs/FLAKE-LEDGER.md makes the flake ledger durable
(digest_parses_a_real_pty_stream hit its second gravity occurrence on the
previous push; entry upgraded with a next-occurrence hardening plan).

Traceability green with int active. Prepping CONTEXT.md retirement note (task 4):


425	**cross-instance context freshness** (two-tier):
426	When a dormant instance is activated again, it is unobtrusively fed the latest Psyche context — newest-among-peers *and* newer than its own. Scoped by the existing Psyche-context split:
427	- **live context** (per-agent, project-independent — the agent's general mind): synced to **all** instances of the endpoint, regardless of project.
428	- **project context** (per-agent-per-project — project-specific detail): synced **only** to instances sharing the **same project**.
429
430	So all `ling` instances catch up on live context; only same-project `ling` instances catch up on project context. This resolves the "divergent simultaneous work" concern (two instances on different projects don't clobber each other's project detail) without losing the "mind follows everywhere" property.
431
432	The precedence/freshness guard (KNOWN-HAZARDS 6.5) — with node identity in the marker — keeps a dormant instance's stale context from clobbering the active authoritative one.
433
434	**Authoring directives + memformat** (full design: `docs/CONTEXT-MEMORY.md`): the live/project split is made stable by (1) a per-*topic* cross-project discriminator with default-to-project bias, (2) **commune-source asymmetry** — echo communes are project-primary and live-conservative (the leak fix), and (3) **deep memformat integration** — memformat becomes the load-bearing, self-evolving, **tier-tagged** schema (each topic tagged `live`/`project`, decided once at creation, re-tiering migrates content), whose topics are containers of **structured blocks** (id + Concepts/Aliases/Applies-to + Source + timestamps + Hash + Pinned). A generated **Retrieval Map (INDEX)** per project + per agent realizes cross-agent synthesis + query-routing. **Start-injection** is dense on the working set (live + current-project hot/`Pinned` blocks → immediate productivity) and sparse on the tail (other projects, cross-agent synthesis, cold blocks → pointer + INDEX, on-demand), tunable via a density knob. Several patterns adapted from `BigscreenVR/pi-agent-memory`.
435
436	### Off-node reach-back
437
438	When the user is driving an instance from off-node, the agent should be able to:
439	- **detect** that it is being driven remotely (and from which node) — observable from the `spt-daemon`, which knows whether the driving session-surface stream is local or network-attached; (v1)
440	- **transfer files** to/from the user's (driving) node — file payloads over the messaging substrate; (v1)
441	- **run commands** on the user's node — remote command execution, **deferred + security-gated** (shares the consent model with instantiate-anywhere; arbitrary cross-node exec is the highest-risk capability in the system). Deferred partly because workarounds exist: the remote-node agent can message a local-node agent to run the command, or the user can interact with a local-node agent directly. (deferred)
442
443	### v1 scope line (V1-mid)
444
445	- **In v1:** the endpoint-ID / instance data-model split; the subnet registry; resolution policy; remote-drive of *already-running* instances (network session-surface); cross-node Psyche sync (full — replaces gh-repo-sync); cross-instance context-freshness auto-feed; off-node file transfer; off-node remote-drive detection.
446	- **Seam-compatible but deferred:** instantiate-anywhere + its consent gate; remote command execution + its security gate (workarounds: remote agent messages a local agent, or user interacts with a local agent directly).
447	- **Rationale:** the data-model split and registry are foundations — deferring them forces a later rewrite, so they are in regardless. Remote-drive of a running instance is the highest-value slice and exercises the whole networking+daemon stack end-to-end. Instantiate-anywhere and remote-exec carry consent/security design that should not gate v1.
448
449	## Workspace & versioning
450
451	The crate-boundary design is the rebuild's main value (ADR-0001) — honest decoupling that prevents the sister project's tangle from re-forming. Principle: **many small, acyclically-layered crates** (not a few fat ones).
452
453	Layering (bottom → top): `spt-proto` (wire envelope grammar, endpoint types, message framing, Ed25519 identity types, typed+binary payload schema — pure types, no I/O) → `spt-store` (spool, perch layout, trust store, registry persistence) → `spt-msg` (delivery TCP+spool-fallback, routing, send/ring) → `spt-net` (Iroh, mDNS, SPAKE2/TOTP pairing, subnet-registry distribution; `net` feature-flagged) and `spt-term` (session-surface trait, PTY impl, broker) and `spt-runtime` (`AgentRuntime` trait, `ManifestRuntime`, manifest schema) → `spt-live` (Psyche/pulse/commune/signoff) → `spt-daemon` (the brain: ties all, hosts broker, update orchestration, instance registry) → `spt` (the `spt.exe` binary; thin CLI).
454
455	**public SDK surface** (semver-committed): `spt-proto` (the wire contract — anyone speaking SPT depends on it), `spt-runtime` (the trait third-party harnesses implement), `spt-msg` (the deeper messaging-integration path). Everything else (`spt-store`, `spt-net`, `spt-term`, `spt-live`, `spt-daemon`) is internal/unstable pre-1.0 — reachable, but no stability promise. The *integration* crates are stable; the *machinery* churns.
456
457	**wire-protocol version vs crate semver** (orthogonal, never conflated): `spt-proto` carries an explicit **wire-protocol version** independent of crate semver. Two nodes — or a node and a linked library consumer — interoperate iff their proto versions are compatible, with a documented **N-1 compat window**. Crate semver governs *API* stability; proto version governs *wire* stability.
458
459	## Pairing & trust
460
461	How a single user's own nodes come to trust each other and form a subnet. Cross-*user* subnet (two *different* users' subnets interoperating) is explicitly deferred (the sister project's "cross-subnet contract" — very-early future concept), but the model is **built with the seam for it** (see *subnet membership*).
462
463	**subnet membership (multi-subnet)**:
464	A node may be a member of **multiple subnets at once** — but, for v1, only multiple subnets *of the same user* (e.g. a `home` fleet and a `work` fleet, each cryptographically its own TOTP seed + trust context). A node simply holds *N* seeds / trust-contexts rather than one. The per-subnet trust boundary is unchanged: within each subnet, all nodes are the one user's own mutually-trusted nodes (no stranger-auth). **Cross-*user* membership (joining another person's subnet) stays deferred**, but the membership model is multiplicity-ready so it can drop in later without re-architecture. An **external subnet** (relative to a given subnet) means *another subnet the node also belongs to* — in v1, always another of the user's own.

**cross-instance context freshness** (two-tier):
When a dormant instance is activated again, it is unobtrusively fed the latest Psyche context — newest-among-peers *and* newer than its own. Scoped by the existing Psyche-context split:
- **live context** (per-agent, project-independent — the agent's general mind): synced to **all** instances of the endpoint, regardless of project.
- **project context** (per-agent-per-project — project-specific detail): synced **only** to instances sharing the **same project**.

So all `ling` instances catch up on live context; only same-project `ling` instances catch up on project context. This resolves the "divergent simultaneous work" concern (two instances on different projects don't clobber each other's project detail) without losing the "mind follows everywhere" property.

The precedence/freshness guard (KNOWN-HAZARDS 6.5) — with node identity in the marker — keeps a dormant instance's stale context from clobbering the active authoritative one.

**Authoring directives + memformat** (full design: `docs/CONTEXT-MEMORY.md`): the live/project split is made stable by (1) a per-*topic* cross-project discriminator with default-to-project bias, (2) **commune-source asymmetry** — echo communes are project-primary and live-conservative (the leak fix), and (3) **deep memformat integration** — memformat becomes the load-bearing, self-evolving, **tier-tagged** schema (each topic tagged `live`/`project`, decided once at creation, re-tiering migrates content), whose topics are containers of **structured blocks** (id + Concepts/Aliases/Applies-to + Source + timestamps + Hash + Pinned). A generated **Retrieval Map (INDEX)** per project + per agent realizes cross-agent synthesis + query-routing. **Start-injection** is dense on the working set (live + current-project hot/`Pinned` blocks → immediate productivity) and sparse on the tail (other projects, cross-agent synthesis, cold blocks → pointer + INDEX, on-demand), tunable via a density knob. Several patterns adapted from `BigscreenVR/pi-agent-memory`.

### Off-node reach-back

When the user is driving an instance from off-node, the agent should be able to:
- **detect** that it is being driven remotely (and from which node) — observable from the `spt-daemon`, which knows whether the driving session-surface stream is local or network-attached; (v1)
- **transfer files** to/from the user's (driving) node — file payloads over the messaging substrate; (v1)
- **run commands** on the user's node — remote command execution, **deferred + security-gated** (shares the consent model with instantiate-anywhere; arbitrary cross-node exec is the highest-risk capability in the system). Deferred partly because workarounds exist: the remote-node agent can message a local-node agent to run the command, or the user can interact with a local-node agent directly. (deferred)

- **In v1:** the endpoint-ID / instance data-model split; the subnet registry; resolution policy; remote-drive of *already-running* instances (network session-surface); cross-node Psyche sync (full — replaces gh-repo-sync); cross-instance context-freshness auto-feed; off-node file transfer; off-node remote-drive detection.
- **Seam-compatible but deferred:** instantiate-anywhere + its consent gate; remote command execution + its security gate (workarounds: remote agent messages a local agent, or user interacts with a local agent directly).
- **Rationale:** the data-model split and registry are foundations — deferring them forces a later rewrite, so they are in regardless. Remote-drive of a running instance is the highest-value slice and exercises the whole networking+daemon stack end-to-end. Instantiate-anywhere and remote-exec carry consent/security design that should not gate v1.

## Workspace & versioning

The crate-boundary design is the rebuild's main value (ADR-0001) — honest decoupling that prevents the sister project's tangle from re-forming. Principle: **many small, acyclically-layered crates** (not a few fat ones).

Layering (bottom → top): `spt-proto` (wire envelope grammar, endpoint types, message framing, Ed25519 identity types, typed+binary payload schema — pure types, no I/O) → `spt-store` (spool, perch layout, trust store, registry persistence) → `spt-msg` (delivery TCP+spool-fallback, routing, send/ring) → `spt-net` (Iroh, mDNS, SPAKE2/TOTP pairing, subnet-registry distribution; `net` feature-flagged) and `spt-term` (session-surface trait, PTY impl, broker) and `spt-runtime` (`AgentRuntime` trait, `ManifestRuntime`, manifest schema) → `spt-live` (Psyche/pulse/commune/signoff) → `spt-daemon` (the brain: ties all, hosts broker, update orchestration, instance registry) → `spt` (the `spt.exe` binary; thin CLI).

**public SDK surface** (semver-committed): `spt-proto` (the wire contract — anyone speaking SPT depends on it), `spt-runtime` (the trait third-party harnesses implement), `spt-msg` (the deeper messaging-integration path). Everything else (`spt-store`, `spt-net`, `spt-term`, `spt-live`, `spt-daemon`) is internal/unstable pre-1.0 — reachable, but no stability promise. The *integration* crates are stable; the *machinery* churns.

**wire-protocol version vs crate semver** (orthogonal, never conflated): `spt-proto` carries an explicit **wire-protocol version** independent of crate semver. Two nodes — or a node and a linked library consumer — interoperate iff their proto versions are compatible, with a documented **N-1 compat window**. Crate semver governs *API* stability; proto version governs *wire* stability.

## Pairing & trust

How a single user's own nodes come to trust each other and form a subnet. Cross-*user* subnet (two *different* users' subnets interoperating) is explicitly deferred (the sister project's "cross-subnet contract" — very-early future concept), but the model is **built with the seam for it** (see *subnet membership*).

**subnet membership (multi-subnet)**:
A node may be a member of **multiple subnets at once** — but, for v1, only multiple subnets *of the same user* (e.g. a `home` fleet and a `work` fleet, each cryptographically its own TOTP seed + trust context). A node simply holds *N* seeds / trust-contexts rather than one. The per-subnet trust boundary is unchanged: within each subnet, all nodes are the one user's own mutually-trusted nodes (no stranger-auth). **Cross-*user* membership (joining another person's subnet) stays deferred**, but the membership model is multiplicity-ready so it can drop in later without re-architecture. An **external subnet** (relative to a given subnet) means *another subnet the node also belongs to* — in v1, always another of the user's own.
