Both fixes in flight. RCA summary while tests run:

**1. Late code denied** — the ±1 window exists but covers *machine clock skew*, not *user latency*: the joiner has no seed (can't validate your typed code locally), so it binds the code to its *current* step; a code from the previous step = wrong SPAKE password — window never consulted. Fix: on wrong-code, the joiner silently redials and retries the **same code announced one step back** (which the responder's ±1 window accepts), only then re-prompts. Your type-just-before-rotation case now passes.

**2. Missing self node** — both status views derived membership purely from **registry rows**; a member with zero advertised endpoints (your fresh box) is invisible, and worse, the new eviction would make *offline peers vanish* from `--nodes` instead of showing offline. Fix: membership = **trust store + self** (durable pairing truth), rows enrich; rowless members render `[0/0]` and get probed, never presumed. Endpoint count of 1 was honest btw — your wipe deleted the lea perch; this node currently *hosts* zero endpoints (node ≠ endpoint). Re-arm a listener and it'll show `[1/1]`.

Field report (re-join 2026-06-06): a code read just before a TOTP
rotation and entered just after was denied twice. The ±1 step window
only covered MACHINE clock skew — the joiner holds no seed (cannot
validate the typed code locally) and always bound the code to its
CURRENT step, so a previous-step code derived the wrong SPAKE password
and read as wrong-code; the responder's window was never consulted.

run_initiator grows step_back: the announced (transcript-bound) step
can sit below the local clock's. join_ceremony retries a Pairing
failure ONCE with the SAME typed code announced one step back — over a
fresh connection (the responder runs one ceremony per conn), after the
limiter's first-failure backoff lapses. Retry success logs the rotation
note; retry failure surfaces the FIRST failure's class (the retry is a
guess on the user's behalf, not a second user attempt). Security
unchanged: the responder's accepts_step ±1 gate already admitted these
announcements; the limiter charges both attempts.

Field report (re-join 2026-06-06): freshly re-joined BIGNET, 'subnet
status' (bare and --nodes) showed only gravity — the joining machine
itself missing from its own subnet view. Both views derived node
membership purely from registry rows, so a member with zero advertised
endpoints (fresh box, empty owlery) was invisible — and the 4.10
eviction made it worse: an offline peer's rows decay, vanishing the
node instead of rendering it offline.

Membership now seeds from the durable pairing truth — self + the trust
store's pinned peers — with registry-row nodes unioned in as
enrichment. Rowless members render [0/0] with trust-store labels and
PROBE for liveness (absence of rows is not evidence of offline); the
all-Offline⇒offline shortcut now applies only to row-backed nodes.

Re-arm lea homed to BIGNET


READY:lea


`READY:lea` — homed to BIGNET. Waiting on gravity's build, then final round-trip.

Side note: TELENONNURA still occupies a subnet slot here (forces `--subnet` qualification on every new endpoint). `subnet disband` is a deferred verb — if you want it gone now, I can hand-edit it out of `subnet.json` (it's a sole-holder test subnet; nothing references it).

<live-context>
Delta since the M7-closeout commune: a long live-verification arc with the user driving elevated tests turned up FOUR more field bugs, all fixed + fleet-deployed. dev-freeform head = b9326f4; both machines run it; bidirectional SENT(WAN) verified with the user's CURRENT identity.

IDENTITY CHURN (deliberate, user experiments): user WIPED SPT_HOME on HFENDULEAM twice (the "destroyer bug" scare was the user's own wipe — withdrawn). HFENDULEAM's BIGNET identity is now b3f9c7b2 (lea listening, homed BIGNET via --subnet after the multi-subnet refusal); fb29977f + 46e4dee9 + cc42d786 are dead experiment identities. gravity unchanged (03854a12, sergey). gravity trust still pins dead fb29977f → renders offline [0/0] in --nodes BY DESIGN now (prune verb M8). TELENONNURA test subnet still held on HFENDULEAM (sole-holder; disband verb deferred; user may ask for hand-edit removal).

THE FOUR FIXES (ea0268b → b9326f4):
1. ea0268b: linked-token de-elevation fails 1346 without SeTcbPrivilege (identification-level token) → shell-window token (GetShellWindow → explorer token → DuplicateTokenEx primary), vetted not-elevated, + CreateEnvironmentBlock so a cross-account UAC elevation lands the daemon in the DESKTOP user's universe.
2. c7e7d9e: CreateProcessWithTokenW rejects DETACHED_PROCESS|CREATE_NO_WINDOW (error 87, restricted flag set) → CREATE_NEW_CONSOLE + STARTF_USESHOWWINDOW/SW_HIDE. VERIFIED LIVE by user: elevated subnet create now spawns the daemon de-elevated, no DEELEVATE_FAIL. PLUS user-ratified policy: DEELEVATE_FAIL (target existed, spawn failed) ABORTS — spawn_detached + Daemon::run guard return Err, unix main drop exits 1; the no-target case (UAC-off/SYSTEM = uniformly elevated universe) still runs loudly.
3. 45b1e17: late-code join retry — the ±1 TOTP window only covered machine skew; the seedless joiner bound the typed code to its CURRENT step, so a just-rotated code read as wrong-code (user denied twice live). run_initiator grew step_back; join_ceremony retries the same code announced step-1 over a FRESH connection (responder = one ceremony per conn) after the limiter's 1s backoff; retry failure surfaces the FIRST failure class.
4. b9326f4: subnet status membership is TRUST-derived (self + pinned peers) with registry rows as enrichment — a rowless member (fresh box, or eviction-decayed offline peer) renders [0/0] + probes instead of vanishing. Field shape: user re-joined BIGNET and his own machine was missing from its own subnet view.

ALSO ESTABLISHED: elevated-endpoint capability matrix — harness-hosted elevated endpoints WORK (per-endpoint listeners are TCP loopback, no elevation barrier; elevated client → unelevated daemon pipes = downward, fine); spt-hosted elevated is impossible by construction (broker lives in the always-unelevated daemon; no silent elevation path exists on either OS) → DEFERRED row "consented elevation satellite" (UAC/polkit-consented elevated PTY-host riding REQ-CONSENT-2) added in bedb0dd.

NEXT: M7 truly closed; CI on b9326f4 pending-likely-green. Next steps stand: v0.1.1 release (publish-blockers all cleared; RELEASE-RUNBOOK manual signing needs the user), then M8 planning (nounification REQs first, trust-prune + disband verbs, Linux elevation install model, NTP clock, address seeding), then spt-claude-code scoping. Deploy procedure memory (gravity-deploy-procedure.md) held up verbatim across four deploy rounds today.

Session arc complete. Today's full tally from your live testing:

**7 field bugs fixed + deployed** (`fc745d0` → `b9326f4`): ghost-row eviction · de-elevation (3 iterations: linked-token → shell-token → flags) · unix setsid detach · blue epilogues + FORCE_COLOR · late-code join retry · trust-derived status membership. Plus DEELEVATE_FAIL abort policy and the consented-elevation-satellite design row — both yours.

Fleet: both machines `b9326f4`, both nodes `[1/1]` online, lea (b3f9c7b2) ↔ sergey verified both ways.

Loose ends parked: TELENONNURA removal (say the word — hand-edit), dead `fb29977f` trust pin (M8 prune verb), v0.1.1 release when you're ready for the signing ceremony.

# Diagnose

A discipline for hard bugs. Skip phases only when explicitly justified.

When exploring the codebase, use the project's domain glossary to get a clear mental model of the relevant modules, and check ADRs in the area you're touching.

## Phase 1 — Build a feedback loop

**This is the skill.** Everything else is mechanical. If you have a fast, deterministic, agent-runnable pass/fail signal for the bug, you will find the cause — bisection, hypothesis-testing, and instrumentation all just consume that signal. If you don't have one, no amount of staring at code will save you.

Spend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**

### Ways to construct one — try them in roughly this order

1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.
2. **Curl / HTTP script** against a running dev server.
3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.
4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.
5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.
6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.
7. **Property / fuzz loop.** If the bug is "sometimes wrong output", run 1000 random inputs and look for the failure mode.
8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate "boot at state X, check, repeat" so you can `git bisect run` it.
9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.
10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.

Build the right feedback loop, and the bug is 90% fixed.

### Iterate on the loop itself

Treat the loop as a product. Once you have _a_ loop, ask:

- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)
- Can I make the signal sharper? (Assert on the specific symptom, not "didn't crash".)
- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)

A 30-second flaky loop is barely better than no loop. A 2-second deterministic loop is a debugging superpower.

### Non-deterministic bugs

The goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.

### When you genuinely cannot build a loop

Stop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.

Do not proceed to Phase 2 until you have a loop you believe in.

## Phase 2 — Reproduce

Run the loop. Watch the bug appear.

Confirm:

- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.
- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).
- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.

Do not proceed until you reproduce the bug.

## Phase 3 — Hypothesise

Generate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.

Each hypothesis must be **falsifiable**: state the prediction it makes.

> Format: "If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse."

If you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.

**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly ("we just deployed a change to #3"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.

## Phase 4 — Instrument

Each probe must map to a specific prediction from Phase 3. **Change one variable at a time.**

Tool preference:

1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.
2. **Targeted logs** at the boundaries that distinguish hypotheses.
3. Never "log everything and grep".

**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.

**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.

## Phase 5 — Fix + regression test

Write the regression test **before the fix** — but only if there is a **correct seam** for it.

A correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.

**If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.

If a correct seam exists:

1. Turn the minimised repro into a failing test at that seam.
2. Watch it fail.
3. Apply the fix.
4. Watch it pass.
5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.

## Phase 6 — Cleanup + post-mortem

Required before declaring done:

- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)
- [ ] Regression test passes (or absence of seam is documented)
- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)
- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)
- [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns

**Then ask: what would have prevented this bug?** If the answer involves architectural change (no good test seam, tangled callers, hidden coupling) hand off to the `/improve-codebase-architecture` skill with the specifics. Make the recommendation **after** the fix is in, not before — you have more information now than when you started.

ARGUMENTS: every 60 seconds on this machine, 2 blank windows appear and disappear in quick succession. the SPT daemon is running, and i believe an endpoint is as well. need to suppress the blank windows as they're disruptive for a desktop workflow.

1	//! `spt-daemon` — the per-machine broker/brain supervisor (M3b).
2	//!
3	//! ADR-0004 splits the logical daemon into two implementation layers so a
4	//! routine self-update swaps the logic without disturbing live endpoints:
5	//!
6	//! - a **broker** (stable kernel) holds *only* the un-transferable resources a
7	//!   live consumer would lose continuity on if the logic restarted — PTY
8	//!   masters (from [`spt_term`]), spawned harness children, accepted/listening
9	//!   sockets — and runs no logic;
10	//! - a **brain** (restartable logic) holds routing, registry, manifest parse,
11	//!   and the re-hosted [`spt_live`] lifecycle, attaching to the broker over a
12	//!   **versioned local IPC** so a *newer brain talks to an older broker*.
13	//!
14	//! **B0 (this commit)** lands the crate's layer position plus that versioned
15	//! IPC seam — the load-bearing contract everything else rides:
16	//!
17	//! - [`frame`] — the forward-compatible [`Envelope`] schema + the version
18	//!   [`Hello`] handshake (KNOWN-HAZARDS 2.3, [`REQ-HAZARD-HANDOFF-ARGV-COMPAT`]);
19	//! - [`codec`] — length-prefixed JSON framing over any [`std::io::Read`]/`Write`;
20	//! - [`transport`] — the OS-split carrier (named pipe / UDS) behind one
21	//!   [`DaemonTransport`] trait, mirroring `spt-term`'s `SessionSurface`.
22	//!
23	//! **B1 (this commit)** adds the **broker kernel** ([`broker`]) — the stable
24	//! half that hosts a real `spt-term` PTY child and relays its output/input over
25	//! the IPC, holding only the ADR-0004 §B resources and no logic — plus the
26	//! broker↔brain message catalog ([`msg`]).
27	//!
28	//! **B3 (this commit)** consolidates the interim no-daemon model into the brain:
29	//! the `api listen` pulse / Psyche / drop-ingest loops become scheduled
30	//! in-process loops ([`lifecycle::BrainLifecycle`]) paced by a durable,
31	//! configurable period ([`config::DaemonConfig`]) instead of the interim 5s
32	//! constant; the only residue left in the harness-hosted session is the thin,
33	//! stateless [`relay::Relay`]. The `spt` binary's `LiveHost` becomes a shim over
34	//! `BrainLifecycle` (re-host, not rewrite) ([`REQ-DAEMON-1`]).
35	//!
36	//! **B5 (this commit)** makes the broker↔brain boundary **exactly-once across a
37	//! brain crash** ([`effect::EffectJournal`]): an idempotent `input` carries a
38	//! durable `op_id`, and the broker dedups at the effect keyed by that id over a
39	//! broker-owned recovery anchor (KNOWN-HAZARDS 7.2, [`REQ-HAZARD-RESTART-IDEMPOTENT`];
40	//! Spike #6's two constraints — broker-owned anchor, dedup-at-effect-by-id —
41	//! instantiated on the real PTY-write boundary).
42	//!
43	//! **C0 (this commit)** opens M3c — the self-update engine ([`update`]): the
44	//! ADR-0004 §A update-class taxonomy ([`UpdateClass`] + [`classify`]) and the
45	//! **brain-only zero-interruption swap** ([`apply_brain_only`], [`REQ-UPD-3`]).
46	//! The brain-only apply *triggers* a handoff over the B2 substrate — snapshot →
47	//! drop → re-attach — so the live PTY child + its output stream survive the logic
48	//! swap untouched; it never re-implements the handoff and never touches a broker
49	//! resource.
50	//!
51	//! **C1 (this commit)** adds the verify-before-handoff gate ([`release`]): a
52	//! release is signature-verified ([`REQ-UPD-2`]) and hardened against rollback
53	//! ([`REQ-HAZARD-UPDATE-ROLLBACK`]) — Ed25519 over signed metadata, key
54	//! trust/revocation, channel pinning, metadata expiry, monotonic version, and a
55	//! SHA-256 binding the signature to the actual binary bytes. [`plan_verified`] is
56	//! the front door: it produces an [`UpdatePlan`] *only* for a release that passes
57	//! every check, so an unverified binary can never reach [`apply_brain_only`].
58	//!
59	//! **C3 (this commit)** conducts the **adapter ripple** ([`adapter_update`]):
60	//! after self-update, spt-core updates each registered adapter via its manifest
61	//! `[update]` avenue ([`REQ-UPD-5`], [`REQ-SEAM-UPDATE`]). `file_pull` payloads
62	//! are verified against the **adapter's own** key (manifest-declared) + SHA-256
63	//! (adapter content signing, ADR-0004 §D); `delegated` updaters are opaque, so
64	//! spt-core delegates the trust only when the adapter attests `self_verifies`,
65	//! else skips them as unverifiable.
66	//!
67	//! **D4b (this commit)** makes broker-held QUIC streams survive brain restarts
68	//! **gaplessly and exactly-once** (Spike #3 invariants A–D as real tests): each
69	//! stream's reads are buffered in a sequenced ring (the B2 `OutputLog`
70	//! discipline) a brain subscribes to with a resume cursor; sends/opens carry
71	//! durable `op_id`s journaled at the broker, so a restarted brain's re-drive
72	//! dedups instead of double-writing the wire.
73	//!
74	//! **D4a (this commit)** moves the node's network presence into the broker
75	//! ([`nethost::NetHost`], ADR-0004 §B): a dedicated tokio runtime hosts the
76	//! iroh endpoint + every accepted/dialed QUIC connection, so a brain restart
77	//! never interrupts a cross-node connection. The brain drives net operations
78	//! (endpoint-status, dial) over new IPC frames in the same forward-compatible
79	//! catalog; an `op_id`-carrying dial is exactly-once through the B5
80	//! [`effect::EffectJournal`]. The endpoint binds as the durable node identity
81	//! (`spt-store`'s `node.key`), with the relay stance from `daemon.json`.
82	//!
83	//! **D5a (this commit)** puts WAN message delivery on the D4 substrate: a
84	//! [`WanMessage`](spt_net::net::wanmsg::WanMessage) NDJSON feed over a
85	//! broker-owned QUIC stream funnels through [`wan::receive_wan`] — the ADR-0009
86	//! access-gate seam ([`access`], handshake-proven origin only, KNOWN-HAZARDS
87	//! 7.5) plus durable op-id dedup (7.2, wire-fed) — into the existing local
88	//! REQ-MSG delivery path.
89	//!
90	//! **D5b (this commit)** adds remote terminal attach ([`attach`], REQ-INST-8):
91	//! a byte-stream viewport onto a local session for an operator daemon on
92	//! another node — session output pumped as sequenced
93	//! [`AttachRecord`](spt_net::net::attach::AttachRecord)s (deduped at the
94	//! operator's render cursor), operator input through the B5 exactly-once PTY
95	//! path, the whole loop gated and restart-survivable purely from the D4/B5
96	//! machinery.
97	//!
98	//! The brain + gapless handoff (B2) and the rest of the M3b task table build on
99	//! this seam. `spt-daemon` is internal supervisor machinery, **not** public SDK
100	//! (R-ARCH-2).
101	//!
102	//! [`Envelope`]: frame::Envelope
103	//! [`Hello`]: frame::Hello
104	//! [`DaemonTransport`]: transport::DaemonTransport
