dispatcher — so `COMMAND COUNT` was advertising verbs Moon could not run.

### Fixed
- **Five Rust SDK helpers sent wire forms Moon rejects on every call; two server-side gaps that
hid them are closed.** `moondb` 0.2.1 → **0.3.0** (breaking: five `pub` methods removed).

Each removed method failed on its first round trip, always, for the whole published lifetime of
the crate — so no caller can have depended on its behaviour, only on it compiling. Two named
commands Moon does not have, and three named real commands with the wrong arguments, which is
why a name-level audit had already cleared them:

| Removed | Sent | Server answered | Use instead |
| --- | --- | --- | --- |
| `MqClient::push_partitioned` | `MQ.PUSH` (a command name) | `unknown command` | `MqClient::push` |
| `MqClient::pop_partitioned` | `MQ.POP` (a command name) | `unknown command` | `MqClient::pop` |
| `VectorClient::upsert` | `FT.UPSERT` | `unknown FT.* command` | `FT.CREATE`, then `HSET` the index's vector field |
| `TemporalClient::snapshot_at_packed` | `TEMPORAL.SNAPSHOT_AT <hlc>` | `wrong number of arguments` | `snapshot_at` (the server captures the timestamp) |
| `TemporalClient::release_snapshot` | `TEMPORAL.INVALIDATE` (no args) | `wrong number of arguments` | nothing — delete the call |

`upsert` was not reimplemented over the real wire form because there is no faithful one: Moon
indexes a vector by `HSET`-ing a hash whose vector FIELD NAME comes from the index definition,
and the signature never carried it. Guessing would trade a loud error for a silent wrong write.
`release_snapshot` has no replacement because its premise was false: `TEMPORAL.SNAPSHOT_AT` never
pinned the connection to a snapshot view — it records a shard-global `wall_ms → LSN` binding that
`AS_OF` resolves later — so no pin is taken and none can be dropped. Callers can simply delete
the call; their reads were already live. `snapshot_at`'s documentation, which described the
imaginary pin, is corrected.

**`TXN` was NOT removed** — `txn_begin` / `txn_commit` / `txn_abort` are correct and stay. An
earlier shell probe appeared to show `TXN` dead; the probe was wrong (zsh does not word-split an
unquoted parameter expansion, so the server received one argument literally named `TXN BEGIN`).

Server-side, two commands were unreachable through introspection because they are served by
intercepts that run *before* the metadata table: `TXN` and `FT.AGGREGATE` are now registered, so
`COMMAND INFO` and `COMMAND COUNT` (265 → 267) report them. Registration is metadata only and
does not reroute either command. Separately, a bare `TXN` or an unrecognised subcommand answered
`unknown command 'TXN'`, which is false — the command exists — and misleads a driver into
concluding Moon has no cross-store transactions. It now answers an arity/subcommand error, the
shape Redis uses for container commands and the one driver error handling keys on.

The SDK tree had no CI of any kind, which is how all five shipped. Three guards now run:
a command-NAME sweep over the SDK sources (`tests/sdk_wire_forms.rs`), a live round trip through
every one of the 52 public Rust helpers (`sdk/rust/tests/round_trip.rs`), and a Python
`__version__` derivation check. The round trip is what found `release_snapshot`, after review had
already passed the file — and mutating a helper's argument order fails it while the name sweep
stays green, which is the point of having both.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Correct the reported Rust helper coverage.

The changelog says the round trip covered 52 public Rust helpers. .add/tasks/sdk-wire-form-fixes/TASK.md records 168/168 helpers driven in Lines 463-468 and 507-508. If 52 is a narrower subset, name that subset. Otherwise, change the release note to 168.

- **`moondb.__version__` reported a release the package had not been for two versions.** The Python
SDK published as `0.1.1` while `__version__` was a hand-maintained literal still answering
`"0.1.0"`, and the test covering it asserted the same stale literal — so the suite stayed green
while every caller reading `__version__`, every bug report quoting it, and anything gating on
"SDK >= x" got the wrong number. It is now derived from installed distribution metadata (falling
back to `pyproject.toml` for an uninstalled source checkout), so it cannot drift again, and the
test asserts the derivation rather than restating the value.
- **Remote panic on the cluster bus: a truncated v3 gossip header killed the process.** The gossip
wire v3 (#493) appended a 40-byte `sender_master_id`, but the deserializer's length guard still
admitted any frame of at least the v2 header size so that a genuine v2 peer would still parse —

PEP 440 version specification local version identifier plus sign 0.0.0+unknown invalid version

💡 Result:

The version string 0.0.0+unknown is a valid PEP 440 version [1][2][3]. According to PEP 440, a local version identifier is constructed by appending a plus sign (+) followed by a local version label to a public version identifier [4][5]. In the string 0.0.0+unknown: - 0.0.0 is the public version identifier. - + indicates the start of the local version identifier. - unknown is the local version label. The local version label "unknown" consists of ASCII letters, which is permitted under PEP 440's requirements for local version labels (which must consist of ASCII letters, digits, and periods, and must start and end with an ASCII letter or digit) [4][5][6]. Because 0.0.0+unknown conforms to these syntactic rules, it is a valid PEP 440 version string. It is commonly used by Python developers as a sentinel value in code to provide a fallback version when a package's metadata cannot be retrieved—for instance, when the package is imported from a source checkout that has not been installed [1][2][3]. While 0.0.0+unknown is a valid PEP 440 version, local version identifiers themselves are generally not permitted when publishing packages to public index servers like PyPI [4][7]. However, this restriction applies to the publication of distributions, not to the validity of the version string format itself or its use in local code environments [4][8].

Citations:


Use a PEP 440-compatible fallback and test the fallback path. 0.0.0.unknown is not PEP 440-compatible, while 0.0.0+unknown is. The current regex accepts the invalid value and rejects the valid replacement. Use a PEP 440 parser in sdk/python/tests/test_version.py. Add a focused test that forces both metadata and pyproject.toml lookup to fail, because the current test reads pyproject.toml and does not exercise the final fallback.

"""ADD task `sdk-wire-form-fixes` — GUARD 3: the version a caller reads is the
version that was published.

`moondb.__version__` was a hand-maintained string literal, and it drifted: the
package shipped to PyPI as 0.1.1 while `__version__` still answered "0.1.0".
Anything that keys on it — a bug report, a server-side compatibility check, a
user pinning a workaround to "SDK >= x" — was reading a number that had not
been true since the previous release. The test that covered it asserted the
same stale literal, so the suite stayed green through two releases.

Asserting the two are equal would only catch the drift AFTER it happened, and
would then be "fixed" by hand-editing the same literal that caused it. So the
fix is structural: `__version__` is derived from the installed distribution
metadata, which is `pyproject.toml`'s `version` by construction. These tests
guard the derivation, not a snapshot of the number.

Written as `unittest.TestCase` deliberately, so it needs NOTHING beyond the
standard library: the CI runner (Ubuntu 24.04 / Python 3.14) has no pytest, and
PEP 668 blocks `pip install --user` while `python3-venv` is not installed —
