Root cause for the lingering mulligan failure: the inline conditional
expression in MsgEnvelope.ToObject
JsonValueKind.Number => el.TryGetInt64(out var l) ? l : el.GetDouble(),
unified its branches to the common implicit-convertible type. long→double
is implicit, so both branches collapsed to double and the integer value
silently widened. Inside an array (idxList:[2]), each element came back
as boxed double; OfType<long> in ExtractIdxList then filtered every
entry out, so swapIndices arrived empty and BuildSwapResponse echoed
the unchanged hand — exactly the diff-against-Deal mismatch the client
flagged as "Card swap failed: AbandonCards[2]/DrawCards[]".
Extract a ParseNumber helper that returns object explicitly so each
branch boxes its own runtime type. Also harden ExtractIdxList to accept
any boxed numeric type (long/int/double/decimal/string) so a future
JSON-parser drift can't silently regress this path again.
Two regression tests:
- FromJson_NumericArray_PreservesLongTypeOnEachElement: confirms the
fix at the JSON-parse layer with a hardcoded "{\"idxList\":[2,3]}".
- Swap_WithIdxListContainingTwo_ProducesHandWithFreshIdxAtPosition1:
exercises the dispatch end-to-end with a Body holding a real boxed
long; asserts position 1 of the response hand is the fresh deck idx 4.

Two issues caught during v1 smoke at the mulligan / first-turn boundary:
1) BuildSwapResponse ignored the player's idxList and echoed the same
3-card hand back. The client diffs the new self[] against the Deal
to compute "drawn cards" — empty diff against the same hand throws
"Card swap failed: AbandonCards[X]/DrawCards[]". Replace swapped
idxs with fresh deck idxs (initial hand was 1/2/3, deck has 4..30
still available). Same hand must flow into Ready since the client
diffs again there. Move the hand computation into a new helper
ComputeHandAfterSwap and have ComputeResponses thread it through
both BuildSwapResponse and BuildReady.
2) The client doesn't transition to the "Opponent's turn…" display
on its own after sending TurnEnd — it waits for the server to push
an opponent TurnStart (per prod TK2 capture line 14). Without it
the UI just sits on the end-of-turn frame. Add a TurnEnd handler
that pushes a minimal TurnStart{spin} and transitions to a new
OpponentTurn phase, which IS the documented v1 stopping point.

Pushing Matched in response to InitNetwork lands it before
MatchingInitBattle() finishes wiring up the OnReceivedEvent handler
and setting status=Connect. The client's Matched-case in
ReactionReceiveUri only transitions to StartLoad when status is
Connect at the moment of receipt; otherwise the frame is silently
dropped at the state machine and the matchmaking UI never advances.
The real connect-handshake sequence (per MatchingNetworkConnectChecker
+ Matching.cs):
1. WS opens.
2. Client emits InitNetwork (cat=general).
3. Server replies InitNetwork ack → _initNetworkSuccess = true.
4. MatchingInitBattle: status=Connect; emit InitBattle; subscribe
OnReceivedEvent matching handler.
5. Server replies Matched → status=StartLoad, StartBattleLoad.
6. Asset load done → client emits Loaded.
7. Server replies BattleStart + Deal → status=Prepared, GotoBattle.
Add AwaitingInitBattle phase, gate Matched on InitBattle receipt, and
gate BattleStart+Deal on Loaded receipt. Update dispatch and
integration tests to walk the new sequence; InitBattle's wire cat is
Matching(2), not Battle(1).
Caught during v1 smoke walkthrough — battle-traffic.ndjson showed the
client receiving Matched/BattleStart at sub-millisecond gaps after
InitNetwork ack, but never advancing past matchmaking.

GameStart already detects the Steam-vs-UDID mismatch produced by
wipe-and-resignup; it now also reclaims the orphan. New
ViewerRepository.MergeAnonymousViewerInto transfers the fresh UDID
from V_new onto V_old in one save (freeing the unique-index slot),
then deletes V_new in a second save. Partial-failure mode is a
benign null-UDID viewer; two rows never contend for the same UDID.
Side benefit: future GetViewerByUdid lookups now short-circuit to
V_old without going through the Steam handler.

The client's OnReceived routing drops any synchronize push whose
resultCode != Success(1) — and absent counts as 0(None), which is
also dropped. Our InitNetwork ack and BattleFinish already included
resultCode=1, but the five lifecycle bodies (Matched, BattleStart,
Deal, Swap response, Ready) didn't, so the client silently dropped
every one of them.
Symptom: battle-traffic.ndjson capture showed the client receiving
InitNetwork/Matched/BattleStart, but the UI stayed at the matchmaking
screen until timeout — Matched/BattleStart were dropped at the
routing layer before they ever reached the state machine. Move the
resultCode injection into the shared EnvelopeForPush helper so every
scripted push gets it.

Wipe-and-resignup left the client stuck with the blank V_new's id in
Certification.ViewerId. /tool/signup is anonymous, so it can't see the
Steam ticket and creates a fresh anonymous viewer keyed on the new UDID;
the Steam handler on the next request resolves to V_old and serves its
data, but no normal-response hook overwrites Certification.ViewerId.
GameStart now compares the UDID-keyed viewer to the auth-resolved one
and emits rewrite_viewer_id when they differ, which Cute/GameStartCheckTask
writes back into Certification.ViewerId.

Engine.IO v3 frames over WebSocket prepend the packet-type byte (0x04
for Message) to BINARY frames, the binary analog of the leading digit
on text frames. The real client honors this and our session was
treating the entire binary frame as the Socket.IO attachment payload —
the msgpack decoder saw 0x04 as a positive fixint and failed
deserialization on every inbound msg event.
Symmetric fix: strip 0x04 from inbound binary frames in
BattleSession.RunAsync, prepend 0x04 to outbound binary frames in
EncodeAndSendAsync. RawSocketIoTestClient gets the same on both
directions so the integration test still exercises the same wire
shape as a real client.
Caught during v1 smoke walkthrough, after the WS upgrade started
succeeding (101 Switching Protocols).

Previous fix used Context.WebSockets.IsWebSocketRequest, but that
requires UseWebSockets() to have already run — and UseBattleNode
(which calls UseWebSockets) is registered AFTER UseAuthentication
in Program.cs, so the WS feature isn't installed when auth runs.
Switch to reading the raw Upgrade header, which works regardless
of middleware order.
Also split the WS handler's "Unknown battle/viewer pair" warning
into two distinct cases so we can tell unknown-BattleId from
viewer-id-mismatch (which lets us see whether the bridge stored
the right viewer or the client is encrypting a different id).

Two issues caught in the real-client smoke:
1) BestHTTP's SocketOptions.AdditionalQueryParams puts BattleId and
viewerId on HTTP request HEADERS for WebSocket-only transport
(NOT on the URL query string as the in-battle/transport.md spec
says). Real clients therefore send them as headers; our handler
was reading from query and rejecting every connect with "Unknown
battle/viewer pair: <bid>/<garbage>". Fix: header-first, query-
fallback (so the integration test still works against TestServer).
2) The Steam auth handler was running on every WS upgrade and
throwing NotSupportedException on Request.Body.Seek (Kestrel's
HttpRequestStream doesn't support Seek, and a WS upgrade is GET
with Content-Length: 0 anyway). It flooded logs and added no
value — the battle node has its own per-connection credentials.
Skip auth when IsWebSocketRequest is true.
Spec correction for in-battle/transport.md to follow.

Prod do_matching captures (data_dumps/captures/traffic_prod_tk2_*) send
the node URL as host:port/socket.io/ with no scheme prefix —
e.g. "node06.shadowverse.jp:13560/socket.io/". BestHTTP's SocketManager
expects this exact shape; the leading ws:// we were sending plus the
missing /socket.io/ path was preventing the client from completing the
post-do_matching connect (eventually times out with "connection timed
out").
Update BattleNodeOptions default, Program.cs override, and both
controller and bridge tests to use "localhost:5148/socket.io/".

The decompiled client's DoMatchingBase.SettingCardMasterId calls
jsonData["card_master_id"].ToInt() with no Keys.Contains guard when
matching_state ∈ {3004, 3007, 3011}. Omitting the field crashes the
client with KeyNotFoundException at Cute.NetworkManager+Connect.

BattlePassRepository._curveCache and MissionCatalogRepository._maxLevelCache
were private-static fields populated lazily on first read from whatever
DbContext happened to be in scope. In production "one DbContext lineage
per process" makes that fine. Under parallel test execution each
SVSimTestFactory owns its own SQLite :memory: DB, so the first reader's
DB (often empty, in tests that don't seed BP) poisoned the cache for
concurrent readers from a seeded DB — assertions like "BP level info
must be present after seeding" failed because the process-static cache
returned an empty list populated by the other test's empty DB.
The first patch attempted a `BypassCacheForTests` static flag, which is
exactly the kind of test-only seam that rots the production code: future
caches get the same flag, repos accumulate hidden knobs, and the
underlying invariant ("a cache populated from arbitrary scope serves
arbitrary scope") goes unaddressed.
Instead, move both caches into the DI-registered IMemoryCache.
AddMemoryCache() registers it as singleton-per-service-provider:
production has one provider → one IMemoryCache → identical caching
semantics to before. Each WebApplicationFactory builds its own
provider → its own IMemoryCache → cache is naturally scoped per fixture,
no cross-test bleed possible.
The ResetLevelCurveCache() method and its three call sites
(SVSimTestFactory.SeedGlobalsAsync, BattlePassServiceTests,
LoadControllerTests) are deleted — a fresh factory owns a fresh empty
cache, no manual invalidation needed.
With this and the previous StoryService fixture-instance fix in place,
ParallelScope.All works: 776/776 in 57s wall clock (down from 59s on
Fixtures, 2m13s pre-parallelism).

NUnit's default FixtureLifeCycle is SingleInstance — every test in a
class shares one fixture instance, so [SetUp]-initialised fields like
_master / _viewer / _service are reset on every test against the same
object. Under serial execution that's fine; under parallel execution
concurrent SetUps wipe each other's Mock setups and the service code
NREs trying to dereference unconfigured stubs.
Compounding it, NewInMemoryDb was being called with nameof(SetUp) which
is the literal string "SetUp", so every test in the fixture also shared
the same EF InMemory database (the provider keys stores by name).
Two fixes:
- [FixtureLifeCycle(LifeCycle.InstancePerTestCase)] on StoryServiceTests
so each test gets its own instance with its own Mocks.
- Suffix the InMemoryDb name with a Guid so concurrent callers never
share a store.

The full-catalog regression test hardcoded "35 active packs as of
2026-05-23" but the controller filters by DateTime.UtcNow against each
pack's commence/complete dates. When two packs (99047, 80047) crossed
their complete_date of 2026-06-01 01:59:59 UTC, the test started
failing with Expected: 35 / But was: 33 — which had been masked all
along by NUnit's trx serializer OOMing on a different test.
The hardcoded count conflated three things that happened to be equal
on the day the test was written: packs in the seed file, packs active
right now, and 35. The test's real intent (per its class docstring) is
"every pack the importer ingests round-trips through /pack/info";
pinning the clock with TimeProvider would solve today's drift but
re-break the moment someone regenerates the seed or retires a pack.
Expected count now derives from the seed file at test time, filtered
by the same predicate the controller uses (PackRepository
.GetActivePacks: IsEnabled && commence <= now <= complete) via the
shared ImporterBase.ParseWireDateTime parser so any date-string quirk
parses identically on both sides. Spot-check on pack 99047 swapped for
"any pack with non-default pack_category" — same schema-fidelity
coverage (non-zero category survives JSON round trip) without pinning
to an id that rotates.

The unit-test suite was spending most of its wall clock writing logs.
NUnit captures stdout per test and embeds it in the trx; with HttpLogging
emitting full request/response per controller call, EF Core SQL at
Information level, and ReferenceDataImporter banners running ~500x
(once per factory construction), the trx grew to 3.2 GB and the NUnit
result-XML serializer OOMed in StringBuilder.ToString() — which the
runner reported as one mysteriously failed test, masking a real
date-dependent failure underneath.
Three sources silenced under environment "Testing":
- appsettings.Testing.json drops Default + Microsoft.AspNetCore +
HttpLoggingMiddleware + EntityFrameworkCore to Warning.
- Program.cs skips app.UseHttpLogging() entirely (avoids the
middleware overhead, not just the log emission).
- ReferenceDataImporter takes optional TextWriters; the test factory
passes TextWriter.Null. Per-importer helpers become instance methods
so they can use the injected writer.
Result on a fresh run with ParallelScope.Fixtures already in place:
- Test duration: 1m46s -> 59s
- Wall clock: 2m23s -> 1m00s
- trx size: 3.2 GB -> 1.7 MB
The previously-masked date-dependent failure (PackControllerFullCatalog
.Info_returns_full_35_pack_catalog_from_production_seed asserting 35
active packs as of 2026-05-23 against a live clock) is now visible and
can be addressed separately.

NUnit's default ParallelScope is Self (serial). With ~736 tests each
constructing its own SVSimTestFactory (full ASP.NET host + SQLite :memory:
+ ReferenceDataImporter seeding 7270 rows from CSVs), the suite was
running ~2m13s serial. ParallelScope.Fixtures drops it to ~1m46s — a
~20% wall-clock reduction with zero new failures.
Stayed at Fixtures rather than All because ParallelScope.All exposes
the process-static BattlePassRepository._curveCache (and likely other
similar caches) to races inside heavy-globals fixtures (LoadController,
PackControllerFullCatalog, StoryService — all consistent failures
under All, flaky 3-7 fails across runs). Within-fixture parallelism
is blocked on cleaning those up first.

Boots SVSimTestFactory (in-memory SQLite + reference-data CSV import),
mints a battle via IMatchingBridge, opens a raw Socket.IO v2 client
against the in-process TestServer, drives InitNetwork → Loaded → Swap,
and asserts the right scripted frames come back in order.
Verifies the full transport stack end-to-end: EIO3+SIO2 framing,
encryptForNode codec, MsgPayloadCodec roundtrip, InboundTracker
pubSeq dedup + ack echo, OutboundSequencer playSeq assignment, and
ScriptedLifecycle's Path-A frame builders.
Note: RawSocketIoTestClient.DisposeAsync skips the graceful CloseAsync
handshake — TestServer's in-process WebSocket implementation can hang
on it. Abrupt Dispose is fine: the server's ReceiveAsync throws
WebSocketException, BattleSession.RunAsync returns, and the handler
completes.

Replace inaccurate GenerateKey docstring (it claimed to port Cryptographer.generateKeyString
