Closes the two mechanism-lens and blast-lens dual reviews of Campaign OP
slice OP1 (86c0a7e0): docs/research/2026-08-10-op1-review-mechanism.md and
docs/research/2026-08-10-op1-review-blast.md.
MUST-FIX M1 (blast): RuntimeCharacterOptionsState gains a HasServerSeed
latch, set by Replace (the PlayerDescription seed) and cleared by
ResetSession. TryFlush/TryFlushIfAutoSaveDue now refuse before the seed
arrives — closing the window where a bot (or, after this commit, the
timer/logout triggers) could flush client-default option words over a
character's real server-side options before any PlayerDescription ever
landed.
MUST-FIX 1 (mechanism): the 480 s auto-save timer and the pre-logoff
flush are now wired into production, closing TS-71 (retired). Both ride
LiveSessionController's own tick/stop transaction via two new hooks
(ConfigureAutoSaveTick/ConfigurePreLogoffFlush), wired once by
GameRuntime's constructor — a Runtime-internal change requiring zero
host edits, exactly as the review identified. The flush body talks to
WorldSession directly rather than through App's LiveSessionCommandRouter,
which is what keeps this off the S2 lock-order hazard (below). Filed
TS-73 for the two OnChanged side-effect cases (weather/day/combat-
target/fog) TrySetOption still doesn't model — pre-anchored to OP4's
Group B consumer binds.
SHOULD-FIX S2 (blast, prerequisite for MUST-FIX 1): TryFlush/
TryFlushIfAutoSaveDue no longer invoke the flush callback while holding
_dirtyGate — the decision is made and cleared under the lock, but the
callback itself runs outside it, closing the lock-inversion hazard the
natural timer wiring would have hit (Runtime tick's _dirtyGate-then-
_gate vs the router's _gate-then-_dirtyGate).
SHOULD-FIX MF-2 (mechanism): TrySetOption now ports the two
PlayerModule-state-mutating cases of CPlayerModule::OnChanged's local
side-effect switch — turning ON IgnoreFellowshipRequests or
FellowshipAutoAcceptRequests clears the other through a real recursive
TrySetOption call, reproducing retail's second 0x0005 (the clear's send
reaches the wire before the primary option's own send, matching the
nested-call order in the decomp). The signature widened from
Action sendAutoSave to Action<uint,bool> so the recursion can send a
different (id, value) than the caller's own; every production call site
now passes WorldSession.SendSetSingleCharacterOption directly.
SHOULD-FIX MF-3 (mechanism): a hand-transcribed 53-row (id, isOptions1,
mask) theory in CharacterOptionTableTests, independently re-derived from
acclient.h's PlayerOption/CharacterOption/CharacterOptions2 enums rather
than copied from CharacterOptionTable.cs — closes the one column with no
id-by-id pin. Also added the pairwise-distinctness check blast NOTE N7
named.
SHOULD-FIX S1 (blast): LiveSessionCommandRouterTests' CH3/CH4 regression
test now drives the REAL TrySetOption binding instead of a hand-rolled
SetOptionBit substitute that had silently drifted from production after
OP1.
SHOULD-FIX S3 (blast): RuntimeCharacterOwnershipSnapshot gains
OptionsAreClean (!Options.IsDirty), included in IsConverged — a module
whose two words happen to cycle back to their default bit pattern while
still dirty is now caught by the combined ownership ledger, not just by
OptionsAreDefaults.
SHOULD-FIX S4 (blast): SaveOptions no longer encodes "did it actually
flush" as PrimaryObjectId 1u/0u (which read as object guid 0x00000001 in
the K2 event stream). Both host adapters now report the identical shape
(Accepted, objectId 0) — the graphical host never could report this
anyway (LiveCommandBus.Publish has no return channel).
SHOULD-FIX S5 (blast): Replace (the server-seed arrival) now also clears
IsDirty/FirstDirtiedAt — a wholesale re-seed supersedes any pending
batched-but-unflushed local intent (retail's own PlayerModule has no
partial-merge path either), documented at the member.
SHOULD-FIX S6 (blast): a cross-check theory asserting CharacterOptionTable's
masks equal PlayerDescriptionParser.CharacterOptions1/2's independently
(the write path vs the read path TurbineChatMembershipGate/
RuntimeSettingsController consume) — guards the exact CH3 failure class.
Also fixed a real allocation regression found while landing MUST-FIX 1:
the naive per-tick flush closure would have allocated on EVERY
LiveSessionController.Tick() call regardless of dirty state, which broke
the K4 headless 30-session resource-envelope gate. GameRuntime.
FlushCharacterOptions now pre-checks Options.IsDirty (itself retail-
faithful — CPlayerModule::UseTime opens with the identical m_bDirty byte
compare) before allocating the flush closure, so the allocation only
happens on the rare tick that might actually flush.
Dispositions on findings not changed this round:
- Mechanism NOTE 6 / not independently re-flagged: a re-entrant MarkDirty
from inside a flush callback can still be erased by the trailing
"_isDirty = false" — pre-existing, unchanged by the S2 lock restructure
(same outcome whether the callback runs inside or outside the lock),
not reachable from any current caller, not a one-liner to close
correctly (needs a per-dirty-period generation token). Left as documented
in the review; worth closing before the Options panel ever flushes from
inside a change handler.
- Mechanism NOTE 9, blast N2/N3/N4/N5/N6/N8: informational or require
touching files this round doesn't otherwise edit (SocialActions.cs,
CharacterOptionsBlobSource.cs, GameRuntimeContractTests.cs) — left per
the "one-liner in a file already being edited" instruction.
Register: TS-71 retired (both remaining SetCharacterOptions flush
triggers now production-wired); TS-73 filed (the two unmodeled OnChanged
presentation-binding cases, pre-anchored to OP4).
Quality bar: Release build green; full solution suite 12,853 passed / 4
skipped / 0 failed (baseline 12,770/4/0 post-OP2 — 83 new tests added,
zero regressions).

The retail Options panel (Campaign OP) needs a Runtime-owned option map
covering all 53 PlayerOption ids and the real batched SetCharacterOptions
(0x01A1) blob before any UI can be built on top of it. Today's surface only
modeled 6 ListenTo*Chat ids and the 0x01A1 builder was a malformed 16-byte
stub (deleted at Campaign CH slice CH3, docs/research/2026-08-09-chat-side-
channels-vs-ace.md).
- CharacterOptionTable.cs: the ONE typed table, PlayerOption id (0x00..0x34)
-> (Options1/Options2 word, mask, IsAutoSave, ClientDefault), transcribed
from acclient.h's verbatim CharacterOption/CharacterOptions2/PlayerOption
enums and byte-verified against IsAutoSaveOption @0x0059A600 (the 21-id
auto-save table) and GetDefaultOptionValue @0x005D2A30 (the Defaults-
button table). Reconstructing CharacterOptions1/2 defaults from the
ClientDefault column independently reproduces 0x50C4A54A / 0x00008700,
cross-confirming the id-mask mapping. CharacterOptionId (SocialActions.cs)
widened from 6 to all 53 ids to match.
- RuntimeCharacterOptionsState: SetOptionBit now resolves through the full
table (was a 6-case switch). New TrySetOption is the ONE shared local-
write-then-send/dirty seam — mirrors CPlayerModule::OnChanged exactly:
write the bit locally first, then either send 0x0005 immediately (auto-
save ids) or MarkDirty for the batched blob, no-op on an unchanged value
(retail's own early-return) or an unmodeled id. New dirty model (IsDirty/
FirstDirtiedAt/MarkDirty/TryFlush/TryFlushIfAutoSaveDue) uses an injected
TimeProvider so it's fully unit-testable without a live clock.
- Both IRuntimeCharacterCommands.SetSingleOption adapters (Direct + Current)
now route through TrySetOption instead of duplicating the write; this
fixes the headless local-write gap the OP1 research flagged (the direct
adapter previously sent the wire message without writing the bit first,
same class of bug CH4 fixed for the graphical host). Both also reject an
id outside the table instead of silently accepting it. LiveSessionRuntime
Factory's SendSingleCharacterOption closure now delegates to the same
seam instead of duplicating write-then-send inline.
- New IRuntimeCharacterCommands.SaveOptions(generation) — the explicit
blob-flush verb (retail's SaveToServer(force: 0)) — wired end-to-end in
both adapters, including a new SaveCharacterOptionsRuntimeCmd on the
graphical router.
- SocialActions.BuildSetCharacterOptions + WorldSession.SendSetCharacterOptions:
the real PlayerModule::Pack body per the wire research's field-by-field
layout — header always 0x460 OR'd with 0x001/0x008 when shortcuts/desired
comps are non-empty, favorite spells always 8 lists, never sets 0x100 or
0x200. Echoes last-parsed shortcuts/favorites/desired-comps/spellbook
filters (via new CharacterOptionsBlobSource) instead of zeroing them.
Conformance: a hand-computed golden byte vector (not generated by the
builder under test — the CH3 builder died of tests that pinned a wrong
shape and looked green) plus a round-trip through PlayerDescriptionParser.
Contract deviation: the 480 s auto-save timer and the flush-before-logout
trigger are implemented as fully-tested pure state-machine logic
(TryFlushIfAutoSaveDue) but are NOT wired into either host's live per-frame
loop or graceful-shutdown sequence in this slice — only the explicit
SaveOptions verb is production-wired. Wiring the timer touches App's
UpdateFrameOrchestrator graph and Headless's tick loop (outside this
slice's Runtime/wire-layer scope); wiring logout risks the already-fragile
graceful-shutdown sequence CLAUDE.md flags. Filed as TS-71 per the plan's
own escape valve ("target: not deferred" with a register row if deferred).
Also filed: AP-193 (the 0x34 HearPKDeathMessages id/mask is ACE-sourced,
unverifiable against the 2013 binary) and AP-194 (GetDefaultOptionValue's
table disagrees with the constructor default for ConfirmVolatileRareUse/
ShowHelm/ShowCloak — retail's own quirk, reproduced not fixed).
Tests: table completeness x53, auto-save/client-default split pinned
id-by-id against the byte-verified tables, unknown/reserved-id rejection
(0x35/0x36 landmines), local-write-then-send on both adapters + the router,
the dirty/flush state machine, SaveOptions, and the wire golden vector +
PlayerDescriptionParser round-trip. Full Release suite: 12,745 passed / 4
skipped / 0 failed (baseline 12,611/4/0 — slice adds 134 passing tests,
zero regressions).
