Plan 01 §8's deployment deliverable, under
`examples/multihost/` (like the `wg_lan` set) since these need
the `tipc` kernel module — and, for the 2-host pair, a live
bearer — so they can't satisfy `test_docs_examples.py`'s
"walk `examples/` and assert rc == 0". `'multihost'` is already
in that test's exclusion list.
- `single_host.py` — boots a 4-actor tree and shells out to
`tipc nametable show` before/during/after. Watching 4 service
names appear in the KERNEL's table and vanish on teardown,
entirely outside any `tractor` API, is the single best demo
this backend has.
- `watch_nametable.py` — the same story push-based, via
`open_topology_events()`: live `[+] published` / `[-]
withdrawn` as actors come and go.
- `host_a_srv.py` + `host_b_client.py` — the cross-node pair.
Note what's absent from both: any IP, hostname or port. Both
sides name the same *service* and the kernel routes it.
- `README.md` — the manual smoke test (bearer setup, `tipc link
list` verify) per §7.3, plus the gotchas: silent crosstalk,
graceful-close-looks-like-`ECONNRESET`, the interim maddr.
Both single-host scripts were RUN against a live kernel and
their real output is what's pasted in the README.

it lands" framing in plan-03 and the example README was stale in
both directions: the branch pin is obsolete, yet you still can't
just `pip install multiaddr`.
Deats,
- §3.2's grammar table is now re-verified against the upstream
merge (`f86519da`) rather than only `baudco@wg_support` in a
throwaway venv. Also notes the codec enforces a 32-byte key,
so a truncated one is a `StringParseError` and not a silently
mangled parse.
- §1 says merged-but-unreleased; the still-open work is spec
registration (py-multiaddr#107 + gh #483).
- §3.4 swaps "pin the branch" for the `[tool.uv.sources]` `rev`
pin, and fixes the `_have_wg_maddr_proto()` recipe it
suggested — probing w/ `Multiaddr('/wg/uAAAA')` now ALWAYS
raises bc the codec wants 32B, i.e. that feature-detect would
report `False` even w/ the proto perfectly well known.
- risk table row goes "#108 not merged" -> "merged but
unreleased".
- example README: `uv sync` alone now suffices bc of the pin;
documents the 32B check and points at
`_have_wg_maddr_proto()` as the gate.
The one surviving `baudco` mention is deliberate, it records
where the grammar was *first* verified.

`_segments()` called `Multiaddr(maddr)` purely to validate, then
swallowed every failure under `except Exception: pass`. That was
harmless pre-#108 — w/o a `wg` codec there was nothing to
validate — but now that the codec is pinned in, the swallow is
load-bearing and disabled: a malformed key sails past validation
into `wg8_pubkey()`, which happily emits a corrupt b64 str, and
the returned struct then fails its own `.maddr` round-trip. No
raise, just quietly wrong output.
Deats,
- add `_have_wg_maddr_proto()`, the gate plan-03 already
referenced but which never actually existed. Impl'd as
`protocols.protocol_with_name('wg')` under
`except ProtocolNotFoundError` and cached in a mod global,
same shape as the TIPC plan's `is_tipc_available()`.
- only validate when that gate is `True`, and let
`StringParseError` propagate — a maddr which doesn't parse
must NOT reach `wg8_pubkey()`.
- keep the degraded split for a pre-#108 install, now w/ an
explicit `XXX` naming the validation you give up.
So parsing stays pure but becomes total-or-raises. Our own
`ValueError`s (missing `/wg/` seg, bare tunnel w/o an overlay
ep) are unaffected, as is the `wg(8)` b64 round-trip.

`tests/test_docs_examples.py` walks `examples/` **recursively**
and subproc-runs every collected file asserting `rc == 0`. Ran
its exact filter against the tree: all 4 of our files were being
collected — including `README.md`, since the filter never checks
the extension, so CI would have literally tried `python
README.md`. These need a real second host + a live `wg` tunnel,
so they can't ever satisfy that gate.
`'multihost' not in p[0]` is already in the test's exclusion
list w/ no dir yet using it, so this is a pure `git mv` — zero
test changes — and it's what the exclusion was plainly there
for. Collection drops 24 -> 20 files, 0 of them ours.
Also records *why* in the two places someone would look before
adding the next one: a callout at the top of the example README
and a note on plan 03's §3.4 deliverables. Anything needing a
second host or live tunnel goes under `examples/multihost/`.
