- every build off macOS has been silent since the 09-02 snapshot (B356): the non-macOS device layer was a stub that opened nothing, and nothing had ever compiled the client for another target; that layer is now the same output stream over cpal — one seam, not two stacks: the ring, the render thread and the rebuild-on-device-change loop are one code on every platform, only the device file differs; the audio thread never allocates, a lost or changed default device is noticed at kira's own cadence, and realtime is `SCHED_FIFO` on unix and MMCSS "Pro Audio" on Windows, either refusable, the ring turning a refusal into a degradation; and the two instruments this bug says were missing exist — a Linux and Windows cross-compile under `clippy -D warnings`, and a live output test that opens the real device and asserts the ring never ran dry, because compiling is not sounding (1920)
- an emote that requires standing still now refuses on the move: `CheckEmoteEligible`'s `0x4000` arm writes an out-param that `DoEmote` turns into a red "You can't do that while moving!" and aborts; 20 emotes of 78 can raise the line, read off the shipped `Emotes.dbc`; SWIMMING is not in the mask, so a swimmer holding still emotes fine, and `IsSelfControlled` is TRUE for an ordinary player, so a feared or confused player emotes away happily (1904); and the cast path gains its equipped-item rung — the button greyed and pressing it still sent: the reference short-circuits to "fits" on four gates, not one, the miss being a zero `EquippedItemSubClassMask`, which means no item required at all, and the rung sits above the crowd-control validator, so a player both stunned and missing the weapon is told about the weapon; that ladder has six arms, not three — CHARMED, FLEEING and CONFUSED join (1925)
- the quest reward's money is the reference's own widget: the tail of the shared `QuestFrameItems_Update` drives `questState.."MoneyFrame"` through `MoneyFrame_Update`, and the two hand-built coin trios become one `MoneyFrameTemplate` instance each at the reference's anchors, which our coins already used; the progress panel stays on coins, being the required-money flow, not the reward one (1928); and the flight master's `!` joins the questgiver sweep, because the green `!` and the gold `!` are the SAME slot, `unit+0xb2c`, torn down once before both queries re-issue; the mouseover re-ask is refuted — the only taxi-status sender has one live caller — and the two queries are not symmetric: the questgiver's goes out on every sweep, the taxi one only when the unit's key moves or on a full sweep, as the wire shows at Dungar Longdrink: 68 questgiver status queries against 1 taxi-node one (1918)
- `GetSpellTabInfo` out of range answers `nil, nil, 0, 0` — the reference returns four values on every path that returns (`0x4b3ce0`), and ours answered a single nil copied from another binding's shape; it matters because stock `SpellBookFrame_OnLoad` calls it unconditionally and then does `id > (offset + numSpells)`, which a nil raises on and (0+0) makes true, hiding every button on the page — the behaviour to match; the argument raises the reference's usage string when absent, and the index truncates toward zero THEN decrements (1931); the perf probe gains a `WOW_PROBE_UNCAP=vsync` arm, because the uncapped present mode is a request, not a schedule — measured, it taxes the number it was meant to pin (11.80 `cpu_ms` uncapped against 14.65 under it), so the default stays uncapped; and the last three test temp paths are keyed on the pid, after concurrent runs raced on one fixed shared file
