feat(pair): diagnosable subnet join — progress, detail, --verbose (v0.17.0 W3)

REQ-JOIN-DIAGNOSTICS (ADR-0030). The field incident showed NO output at all on a
failed WAN join. Four fixes so a join never fails silently:

(a) Live search progress: the CLI runs a tick thread during the (daemon-blocking)
    meet, printing elapsed/deadline every ~3s — silence no longer reads as a hang.
(b) Detailed meet failure: meet_seed_holder composes a diagnosable failure via the
    pure meet_failure_detail — concise (the last concrete error, never swallowed)
    by default, and under --verbose a structured trace: bound IP families (from the
    W1 per-family gate, via NetEndpoint::bound_families), the rendezvous ±1 window,
    attempts vs the 75s deadline, and the last error. Surfaced BEFORE any code
    prompt (a dead subnet must not make the user fetch a code).
(c) Terminal-event propagation: the old single pair_join `_ => continue` swallow
    (why the user saw nothing) is GONE — W2's two-phase returns MetOutcome::Failed
    → render_join_failure on the CLI. Tagged on that real path.
(d) `--verbose` flag on `spt subnet join` (PairMeetReq.verbose, additive
    serde-default) → the failure-detail dump.

Deferred (noted, doyle ok): the SUCCESS-path "what took so long" trace on a
slow-but-ok join — there is no daemon tracing facility (SPT_LOG) to hang it on
yet, and a per-probe frame protocol isn't worth it for v1.

- unit: meet_failure_detail concise-vs-verbose + the --verbose arg parse.
- reference.md regenerated (xtask gen) for the new flag; no internal codes.

Activated REQ-JOIN-DIAGNOSTICS impl+unit (doc was ADR-0030).

be1f4d6 feat(pair): diagnosable subnet join — progress, detail, --verbose (v0.17.0 W3)


W3 committed @be1f4d6. Reporting to doyle.


printf '%s' "doyle — W3 LANDED @be1f4d6: diagnosable join (REQ-JOIN-DIAGNOSTICS impl+unit).
(a) CLI live-progress tick thread during the daemon-blocking meet (elapsed/deadline every ~3s — silence != hang).
(b) meet_failure_detail (pure, unit-tested): concise = last concrete error (never swallowed); --verbose = structured trace (bound families via NetEndpoint::bound_families ← ties W1 / rendezvous ±1 window / attempts-vs-75s-deadline / last error). Surfaced BEFORE the code prompt.
(c) terminal-event propagation — confirmed the old _=>continue swallow is GONE (W2's MetOutcome::Failed→render_join_failure); tagged on that real path, no stub.
(d) --verbose flag (PairMeetReq.verbose, additive serde-default) → failure dump.
DEFERRED per your ok: SUCCESS-path 'what took so long' SPT_LOG trace — no daemon tracing facility exists to hang it on, per-probe frame protocol not worth v1. Noted in REQ + commit.

GATES: spt-net 126 / spt-daemon 383 / spt 261; +new tests; clippy --workspace clean; traceable exit 0; xtask check OK; reference.md regen (xtask gen, --verbose flag, no internal codes).

Now starting W5 (subnet display parity + palette, REQ-SUBNET-DISPLAY-PARITY) — the last build wave: gossip additive Instance fields (bound/controlled+driver/harness_only), remove picker remote-reduction, EpDisplay rework (drop UnboundControlled / Unbound→red-filled / HarnessOnly→amber-hollow / +Suspended gray-filled). Will report when it lands → then W6 fold (twohost ON for W2 seam) + counter-36." | $OWL send doyle todlando 2>&1 | tail -1

Updating memory, then grounding W5 (the final build wave).

Now grounding W5 — the picker `EpDisplay` model + `display_status` + `local_rows` derivation (to mirror for subnet rows).
