adminandClaude Fable 5 effff53f99 feat(wgtunnel): render operator OOB /32 into wg-felhom AllowedIPs (H1 Part 1, [OF-1]) 
renderConf appends a validated, deterministically-SORTED oob_peer_ip /32 so the
operator peer survives self-heal/restart (a runtime wg set was wiped by self-heal).
WireWireguard gains oob_peer_ip (omitempty — absent = byte-identical pre-H1 conf).
Non-hollow tests: sorted+byte-stable, lower-IP-sorts-first, absent-identical,
invalid/v6 rejected.

adminandClaude Opus 4.8 734f45c422 wgtunnel: v4-pin + re-resolve watchdog; FELHOM_WG Critical flips (S4 agent half) 
v4-pin (doc 06 §4.2): renderConf takes a pre-resolved IPv4 literal and writes
Endpoint=<ip>:<port> — never the DNS name, never AAAA. Resolver seam (A records
only, LookupNetIP "ip4"); multiple A → lowest (deterministic fleet-wide);
renderConf stays pure. Resolved IP cached: steady-state Apply = zero DNS + zero
execs. DNS failure keeps the last conf (never a teardown).

Watchdog (loop-only, so Apply's zero-exec steady state is untouched): handshake
age > wg_tunnel.stale_after_seconds (default 180) → re-resolve; IP changed →
re-render + restart (endpoint re-IP recovery); IP same → no churn (throttled
warn). Staleness read reuses wg show latest-handshakes (never dump).

Capability: wg-conf-install/enable/restart/handshake-read flipped Critical=true
(backups ride the tunnel from S4); apt-install + disable stay non-critical.
TestWGCapabilityCriticality pins the set.

Tests + red-proofs a/b/d all fire. No new sudoers grant; no wire/JSON change.

adminandClaude Opus 4.8 312fd5ee29 wgtunnel: client MTU 1420 → 1280 (S3.1, resolve §4.3 open decision) 
The 2026-07-04 CGNAT smoke test found MTU 1420 silently black-holes bulk TCP
on sub-~1480 paths (mobile ~1400, DS-Lite ~1452): handshake+ping stay healthy,
PBS TLS page (and at S4 the backup itself) drops. Set a fleet-wide, permanent,
family-agnostic client MTU of 1280 (RFC 8200 IPv6-minimum floor; outer 1340 v4
/ 1360 v6 fits every realistic path).

Client-only by construction — interface MTU caps box→PBS, advertised MSS caps
PBS→box; the endpoint's wg0 is untouched (zero live-endpoint risk). New const
clientMTU=1280 as the single home; golden pins exact "MTU = 1280" (red-proofed
against a 1420 flip). Stale report.go comment updated. No wire/JSON change.

adminandClaude Fable 5 fb248961c6 wgtunnel: S3 Part 2 — manager state machine + loop + desired raw-consumer seam 
Manager: one-shot registration (marker gate; backoff cap 15m), adopt-lost-marker,
re-key-on-mismatch, REVOKED-STAYS-REVOKED teardown (marker kept, zero execs on
later ticks), no-teardown-on-absent-data, hash-gated apply (zero execs steady
state), restart-not-reload on conf change, self-heal enable. Status stanza with
latest-handshakes-ONLY wg read. Collector WireguardReporter seam. desired.Syncer
AddConsumer fan-out with panic containment. Red-proofs a/b/d run + reverted;
no-key-material-in-logs asserted.
