gramps efe88b8a0b fix(compositor): keep straight alpha in the paste-cache raster — the web widget's recording black box

The element-space raster builds on a TRANSPARENT base but BlitContentRaw's
partial-alpha branch applied the opaque-dst source-over blend: color premultiplied
by the sampled alpha, then alpha forced to 255. Pasting that raster saw a==255 and
straight-copied darkened ink over the scene — a recording box that the raw-bitmap
preview (correct alpha) never showed. Transparent margins and opaque content were
unaffected, which is why every take looped on the page/CSS while the capture was
transparent all along (15:51 dumps: alpha max 255, mean ~19, zero 57%).

BlitContentRaw now takes transparentDst; the raster call passes true and writes
straight color + straight alpha so the paste rows (BlendRowOpaque/Weighted) do the
real source-over onto the opaque master. Master paths byte-identical.

ONE integration test PasteCache_SemiTransparentLayer_RevealsBackdrop_NotOpaqueInk:
50%-blue over red reads (127,0,128) fixed vs (0,0,128) buggy — proven both ways
(verified by stashing the fix: fails before, passes after). Clean build, 0 warnings;
22/23 compositor-class tests pass, the sole failure the documented pre-existing
Composite_FullScene_MasterPixels pixel (1380,700).

Alpha-compositing model: standard source-over with producer-cached surfaces, the
OBS/libyuv paste model already cited in ai.md/MyMistakes (rawvideo recipe, row-blit
BLEND_NONE / straight-alpha branches); full story in MyMistakes (RESOLVED entry).

Per the good-dog rule: one integration test, memory updates (MyMistakes/ai.md/
HANDOFF) in the same commit.

AboutHubTests.cs

Monetization policy locked + dev pause recorded (docs changeset, 2026-08-14): the one paid line becomes an annual subscription — early access $49.99/yr → $99/yr list at GA, grandfather-while-subscribed with lapse → list on renewal (no escalation matrix); free tier unchanged (branding flash is the free tier's billboard + no Alerts, which is the one paid feature); billing NOT locked to itch.io (hunted fact: itch.io has no native subscription billing — candidates Gumroad, whose native affiliate program is the tiebreaker, and Lemon Squeezy); support = in-app bug-report → git issues with a when-I-get-around-to-it cadence + emergency patches. ai.md Monetization section rewritten + stale paid-unlock seams fixed (L115 subscription-entitlement wording, the About hub's tabled billing PremiumUrl seam); TASKS.md gains TASK 23 (Monetization — billing provider decision, unlock mechanism with lapse→flash-returns enforcement, in-app bug-report loop, Unlock Premium seam lighting, Alerts gating, and line-item pointers for the early-access strategy, affiliate/ads phase 2, and the channel revival); HANDOFF.md records the decisions + the development pause (resume streaming = pair-programming dev streams via OBS + The Division 2 under the gramps/GOAT persona, 67 and gaming since 1981, 3D-printing content retired; dogfood switch to ytLlive once TASK 5 lands; resume point = TASK 5). Stale itch.io assertions corrected across comments and indexes (MainViewModel.cs PremiumUrl/IsPremium seams, MainWindow.xaml tooltip, AboutHubTests comment, ViewModels/index.md, TASK 9 out-of-scope note). Build 0 warnings, 196 tests passing

AudioMixerTests.cs

TASK 8 meter scaling: +10 dB input amplification in AudioLevelMeter.ToDisplay so the meters use the full bar — speech peaks (~0.2 RMS, -14 dBFS) read ~0.93 (red zone) and normal speech (~0.05, -26 dBFS) ~0.73 (yellow) at maxed volume, instead of hovering at the red edge; ≤0.001 linear still reads zero so the meter never idles on background noise; one knob shared by the mic bar and the game bar (× MicVolume gain-on-noise untouched); tests updated + new ToDisplay_Pushes_Speech_Peaks_Into_Red_At_Maxed_Volume — 171 tests passing, 0 warnings

AudioPipelineTests.cs

TASK 25: master limiter on the live mix (2026-08-15, queued from the TRAX discussion) — the review confirmed two of the creator's three instincts were already satisfied (MediaFoundationReader streams from disk so file size needs no guard; the MusicPlayer 0.20 bed rides the same loopback gain as the game, so music is always exactly 20% of the desktop volume by construction) and found one real gap: AudioMixer.FillAndMix summed mic + loopback with no output ceiling, so hot gains could pass 0 dBFS and clip the AAC encode. New pure Services/Audio/MasterLimiter.cs: -1 dBFS ceiling (Ceiling = 0.891), instant attack per frame (a hot frame is scaled exactly to the ceiling — no overshoot), smoothed release toward unity so loud passages don't pump, gain never exceeds 1. Applied at the end of FillAndMix right before the pipe write. 3 unit tests (trim-to-ceiling, never-boost, recovery) + ONE integration test (MasterLimiter_CapsTheLiveMix_OnThePipe: a 0.95 loopback bed capped to exactly 0.891 on the wire while staying audible). Docs in the same commit: ai.md go-live audio section, Services/index.md new row, TASKS.md TASK 25 record, HANDOFF.md shipped state. Build 0 warnings, 193 tests passing (189 + 4 new)
