Product: brand, licensing, monetization & distribution

What the product is called, what it promises, what it may never do legally, and how it ships. Read before branding, marketing, pricing, licensing or packaging work.

Brand

The UI design standard is DESIGN.md — colours, type scale, spacing, radii and elevation, all normative, implemented by Themes/Tokens.xaml. Accent blue #38bdf8 is the only interactive accent; red #ff5451 means live/record and nothing else. The old brand red #e94560 is retired from app chrome (the wordmark/logo artwork is unchanged).

Marketing palette, official assets and copy live in MARCOM.md (gitignored — read it before any branding or marketing work).

Product name vs repo/assembly branding (2026-09-14)

The product is llamacasty (llamacasty.com, llamachile.tube, llgit.llamachile.tube). The repo path, csproj AssemblyName/RootNamespace, DB/log paths (%APPDATA%\ytLlive\...), and most internal namings are the legacy ytLive/ytLlive — a re-brand that never renamed the internals. Treat the two as separate: external/user-facing language says "llamacasty", code/assembly/repo names stay ytLive. If a full internal re-brand is ever done, this note and the UI locator (Premium/wordmark) are the checklists; it is NOT a goal pre-1.0.

Say "LlamaCasty" when reporting to the creator — never "ytLive" in prose. ytLive is the internal repo/assembly/namespace name only. Exact current split:

surface	name	note
product / site / marketing	LlamaCasty	llamacasty.com, llamachile.tube
repo dir, csproj, RootNamespace	ytLive	230 files: namespace ytLive.*
AssemblyName → shipped exe	ytLive	ytLive.exe
app data dir	%APPDATA%\ytLlive	capital L, drifts from ytLive
Distribution.md tells customers	LlamaCasty.exe	⚠ mismatch vs the real ytLive.exe

Consequences, so nobody re-hunts them:

• Renaming <AssemblyName> to LlamaCasty is the cheap win (the customer-visible exe name matches what Distribution.md already promises; namespaces can stay ytLive.*). It is 4 lines, but it hard-breaks three pack URIs that spell the assembly name: MainWindow.xaml:14 (the window icon — taskbar/Alt-Tab), OverlayHost.xaml:96, RenameRecordingDialog.xaml:5. Miss those and you ship a broken icon. Queued in TASKS.md under the shipping task, not done.
• Renaming the %APPDATA%\ytLlive folder is breaking — it would orphan every existing user's layout DB, Assets and settings. Never do it casually; needs a migration.
• No code compares its own assembly name (no GetExecutingAssembly().GetName().Name checks), so the assembly name is otherwise free to change.

AI transparency

This project is built through AI-assisted pair-programming. All code is generated under the supervision of an experienced developer with decades of coding experience. Architecture decisions, product direction, and quality gates are human-owned; AI accelerates implementation. This is a testimonial to successful human-AI collaboration, not autonomous code generation.

Licensing — proprietary since 2026-10-30

LlamaCasty is closed-source commercial software. LICENSE is the EULA; the paid tier exists because output quality is the paid delta — the free tier is capped at a 720p30 profile (creator ruling 2026-10-30, superseding free-forever). Prices, entitlement and channels: commercial.md.

• Every GPL build already published stays GPL for that snapshot. Attribution/§7 terms (ADDITIONAL-TERMS.md) are deleted and were GPL-only; the files are gone.
• No GPL third-party component may be linked. ffmpeg stays a separate subprocess (LGPL, relinkable via the shared build), OpenH264 ships as Cisco's binary, the rest are MIT/Apache/CC0. Never add a statically linked GPL library — that would make the commercial build undistributable.
• Obligations that still bind (they are third-party, not ours): keep THIRD-PARTY-NOTICES.txt shipped and shown in About, ship full licence texts at v1, keep the ffmpeg pin immutable and lgpl-shared, never use the nonfree variant, keep icon art CC0/public-domain, keep the ML model provenance clean (Google MediaPipe, Apache-2.0 — no model-zoo re-hosts).
• Fonts: Inter + JetBrains Mono are OFL-1.1, bundled as separate files with their licence text — allowed in a commercial product, but the fonts may not be sold on their own and must not be modified under the reserved names.
• Brand artwork (name, icon, logo) is the publisher's property; the EULA grants no trademark rights and forbids implying endorsement.
• No source offer. The GPL §6 source link is gone; the repo is private.

Design Principle

This software is so intuitive that even the most right-brained person can easily intuit and use it.

Apply this to every UI decision:

• One-click go-live with working defaults
• Prefilled YouTube defaults (RTMP URL, bitrate, resolution, latency)
• Visual/drag-and-drop scene building over property panels
• Every action produces a visible outcome — no dead ends
• "We're not them" (2026-09-01): assume the creator's hardware is mediocre, because it is. Every feature spends the machine's budget once — never twice for the same result (record OR stream, not both; one reusable stream; one webcam; two mixer inputs). If a feature only sings on a high-end chassis, it doesn't ship — the OBS escape hatch is open by design.

Monetization — free tier + Pro output quality

Every feature is free and ungated (creator ruling 2026-10-08, TASK 54, kept by the 2026-10-30 freemium ruling): no feature lock, no watermark, and nothing licence-shaped in the output. The paid delta is output quality alone — free is capped at a 720p30 profile, Pro unlocks the higher tiers for both the stream and the recording. Prices, entitlement and channels: commercial.md. Support is email + GitHub issues; an in-app bug reporter is out of product.

The branding credit is retired as a paid delta and stays off. MainViewModel.ShowBrandFlash (internal static, default false) is the master switch; BrandFlashEnabled => ShowBrandFlash && !IsPremium feeds the presenter. The code is kept, not deleted — creator ruling: "don't delete it, just make it conditionally displayed." Entitlement must never enable it. BrandFlashOutputTests opts in by setting the switch before constructing a MainWindow; Credit_IsOffByDefault_EvenOnTheFreeTier guards the default.

If it is ever enabled, the mechanics that matter:

• Full-frame neon "made with LlamaCasty!" at a random position per presentation, held 2s (500ms in / 1000ms full / 500ms out), first ~5s after start then every rand(30s)+30s.
• Published to the frame pump and the preview from the same VideoFrame, so preview and broadcast cannot drift. Deliberately not folded into SceneGraph.GetBakedBase — the bake cache compares element ids and would freeze the credit in place.
• App-lifetime cadence: the presenter is Start()ed once in the MainViewModel ctor, not per go-live, because go-live and local recording share one FramePump. IsPremium's setter therefore restarts the cadence timer when re-enabling (IsCadenceTimerEnabled is the test seam).
• It composites into the recording and the stream (reversed 2026-09-26 — the free tier must be honest advertising). Test arithmetic trap: Advance(5.1) in one call blows through the 2s window (it both opens and ages the presentation) — step in 1/30s increments like BrandFlashOutputTests.
• A mid-credit downgrade cuts the advertisement on the next tick: the presenter re-checks its own Enabled gate every frame rather than letting the credit finish.

Live prices, entitlement and channels: commercial.md. Retired pricing, the Store IAP plan and the rejected alternatives: decisions.md.

Monetization awareness (built-in, ungated, free — 2026-09-01; v1 SCOPE per the complete-v1 ruling — build order: capture → report → journey → Alerts): the app is monetization-aware by design, for every creator, free and ungated. It has three layers, all free — the capability no competitor ships (the positioning order across features lives in MARCOM.md):

• Reward-event capture (the data foundation). The live-chat poll (YouTubeChatService.Poll) receives every reward event over liveChat/messages and — since TASK 43 (2026-09-24) — decodes all six types, not two: superChatEvent, superStickerEvent, newSponsorEvent, membershipGiftingEvent, giftMembershipReceivedEvent, memberMilestoneChatEvent land as ChatMessage.Kind (ChatEventKind) with their payload fields (display string, sticker description, gift count, gifter name, milestone months); free subscriptions emit NO event (API fact — a sub mention is a plain text row). The remaining half of the original capture plan stays open (TASK 3 item 20): persist each event to the canonical SQLite RewardEvents table (broadcastId, type, timestamp, amountMicros, currency, tier...) + superChatEvents.list (30-day lookback) backfill — that persistence is what the session report and the journey tracker read. Alerts did not wait on it: the shipped alert path (TASK 43) renders directly from the in-memory ChatMessage feed.
• Session / broadcast report. A session is created at Go Live; the poll + End roll that session's reward totals (new members, Super Chat , stickers , gifts, milestones). This is the in-app replacement for the emailed external "stream activity report" — the incumbents (Streamlabs et al.) email near-useless post-stream summaries; we track the same data natively and maintain it.
• Journey tracker (TASK 39, slice 1 shipped 2026-09-22). A "YPP" tab below the Stream Settings pull-out (Live screen right edge) shows the connected creator's position toward each YPP tier threshold. Slice 1 = current-scope data only: channels.list?mine=true &part=statistics,contentDetails (subs/views/videos + uploads-playlist id) + playlistItems.list for 90-day public uploads. Every refresh appends a YppSnapshot to SQLite (schema v10) — the history a later slice needs for velocity/ETA. The auditDetails part is OUT (fixed 2026-09-23): readding it 403s the WHOLE request — that part alone requires the youtubepartner-channel-audit scope no app for normal creators should request (the standing flags sat unreadable since slice 1 shipped; the app's youtube + youtube.force-ssl scopes were never sufficient for them — the "no re-consent" slice-1 claim was wrong for that part). Channel standing now deep-links to the Earn page; API stats come from statistics,contentDetails only. YPP/API failures log the response body's error.reason. YPP thresholds are versioned, date-aware DATA, never constants — the Tier-2 bar doubles for new applicants on 2027-02-01 (long-form 4,000 → 8,000 qualified hrs / 365d; Shorts 10M → 20M / 90d), while the Tier-1 fan-funding bar (500 subs / 3,000 hrs / 3M Shorts) is unchanged. Hardcoding the pre-2027 numbers would ship the wrong ETA. Watch-hours / Shorts / velocity / ETA are slice 2: Analytics-API scopes (yt-analytics.readonly, additive yt-analytics-monetary.readonly) behind the IChannelStatsProvider seam (additive capability, requires an OAuth re-consent). Compliance items no API exposes (2FA, AdSense linkage) are in-app self-reported checkboxes with deep links; channel standing (exposed only via the partner-audit scope) deep-links to the Earn page. Slice 2's once-daily refresh gate + snapshot history were baked into slice 1.

Auth gates Go Live, but not exploration

The app is fully usable without authentication: users can build scenes, add sources, compose previews, and audition the software with zero commitment. But going live requires authentication — it's the one capability gated behind YouTube sign-in. The sign-in should never pressure the user ("sign in (optional)", not a modal wall): the two-state top bar shows Start Stream (offline) / End Stream (live), and the Start Stream dialog hosts the account — a saved session appears as the default with "Change Account"; with none saved, a "Sign in to YouTube" button starts OAuth and the Start button stays disabled until signed in.

Account assumption (do not build an account setup flow)

Connecting uses Google OAuth ("Sign in with Google") to link an existing YouTube creator account. ytLlive never creates or sets up accounts — that is YouTube's job. If the creator has no YouTube channel, they go to YouTube first. This assumption is explicit and must never be silently replaced by an in-app account-creation step. Zero state = the Start Stream dialog's "Sign in to YouTube" button; going live is unreachable until an account is connected.

Windows packaging & distribution (winget primary; Steam + Store parked)

Live channel policy, the artifact and signing costs: commercial.md. Build mechanics (publish flags, GitHub Releases, the winget manifest): Distribution.md. Retired routes and cause of death: decisions.md.

The channels, in order: direct download from llamacasty.com (binaries on GitHub Releases) → winget, the primary install path → Steam (parked, $100, lifetime Pro as DLC only) → Microsoft Store (parked, $19 Individual account — the only storefront that bills a subscription natively).

Consequences that are architecture, not packaging detail:

• ⛔ There is no self-updater, by policy as well as by history. Velopack was removed on 2026-10-22 (TASK 48 slice 3) because it downloaded and executed, which Store policy 10.2.2 forbids — and the same rule would close the Store for good if it came back. Updates arrive through the package manager (winget upgrade) plus an in-app "newer version exists" banner read from a version file on GitHub Releases. ytLive.Tests/StorePackagingTests.cs must keep asserting that no self-updater returns.
• The MSIX package stays buildable via scripts/package-msix.sh (TASK 48 slice 2) — publish Release -r win-x64 --self-contained into artifacts/msix-stage, copy Packaging/Package.appxmanifest in as AppxManifest.xml + Packaging/Assets/, then makeappx pack → artifacts/LlamaCasty.msix (159 MB, gitignored; MSIX_PFX signs it for a local install). It is the Store channel's artifact, unsubmitted until that account exists. The manifest is a full-trust packagedClassicApp at mediumIL with runFullTrust + webcam + microphone. Square310x310Logo/Wide150x150Logo traps are in MyMistakes.md. Logos come from the app's own artwork via scripts/make-store-logos.py.
• ⛔ Bundle ffmpeg — no runtime downloads (was Store policy 10.2.2; still right for a direct download, and it fixes the 2026-09-01 404). See output.md → "FFmpeg locator".
• ⛔ 64-bit Windows only (creator ruling 2026-10-09). Both csproj files set <PlatformTarget>x64</PlatformTarget> (the test project too — an AnyCPU test project referencing an x64 app raises MSB3270 and breaks the 0-warning gate). Why: the bundled ffmpeg is the win64 build, ONNX Runtime 1.31 ships no win-x86 native (only win-x64/win-arm64), and a 32-bit address space can't hold the 1080p frame buffers. Windows 11 is 64-bit-only anyway. Public copy says "64-bit Windows 10 or 11".
• Portable mode is the distributable's shape: portable.txt beside the exe keeps the layout DB and settings in .\data\ (hung off LayoutPathOverride), so a USB stick carries someone's scenes. The winget install and the hand-to-a-friend zip are the same artifact.

What does NOT change: no watermark and no feature gating. The free tier is the whole app at a 720p30 profile. Monetization above governs.

⛔ Durable invariant: full trust, or recording silently breaks

MSIX packages run at one of two trust levels. A packaged WPF app declaring rescap:Capability Name="runFullTrust" runs at mediumIL — the same permissions as a standard desktop app, NOT AppContainer — and may spawn child processes, which is why bundling ffmpeg is legal. Writes to user-profile locations (AppData, Downloads, MyVideos) pass through unvirtualized at mediumIL; the package install folder is read-only.

ViewModels/MainViewModel.Recording.cs writes recordings to %USERPROFILE%\Downloads / SpecialFolder.MyVideos (DefaultRecordFolder(), ChooseRecordFolder() via Microsoft.Win32.OpenFolderDialog), and the whole temp-write-then-move lifecycle stays in one directory. That works only because we are full trust. No broadFileSystemAccess capability is needed, and none should be added.

⚠️ If anyone flips the manifest to appContainer, Directory.CreateDirectory and File.Move start resolving to a per-package virtualized location and output vanishes with no error. A comment at DefaultRecordFolder() is owed when the manifest lands (TASK 48 item 6) — not before; a comment describing a manifest that doesn't exist is worse than none.

Signing — Azure Trusted Signing, never EV

Microsoft removed the SmartScreen instant-bypass for EV certificates in March 2024, so EV ($400+/yr) buys what OV ($150–300/yr) buys; both need an HSM or hardware token and renew inside 460 days. The 2026-10-31 ruling is **Azure Trusted Signing ($9.99/month)**: Microsoft-issued, individuals eligible after identity verification, and it accrues reputation without a certificate purchase. Until the profile exists, builds ship unsigned and the "unknown publisher" line is accepted. Signing never clears the warning on day one either way — only download volume does. Signing steps: Distribution.md.

Distribution and licensing are independent — the channel never decides billing

A Store-distributed app may still verify licences with Polar (Store policy 10.8.1 explicitly permits a secure third-party purchase API for non-game PC products), so "which channel?" never implies "which billing?". Polar is the live provider (2026-10-31) because the 2026-10-30 freemium ruling created something to sell; winget has no storefront at all, so the licence path is entirely ours there. The lesson worth keeping: the licensing choice rides on a monetization decision, not on a distribution decision.

⛔ "Only when the user says so" is enforced by Windows, not by us

Camera/mic consent is layered: Store policy 10.6 forbids circumventing OS checks; the Windows desktop-app camera/microphone toggle (Settings → Privacy & security, since Win10 1903) is the gate; hardware lights and tray indicators are the OS's disclosure mechanism. So route everything through the standard MF/DShow/WASAPI paths and we never write that certification ourselves — the OS does it and gets neither our credit nor our blame.

⚠️ Untested: whether that toggle reliably gates a DShow webcam and a capture card. Microsoft's own support page admits desktop apps "might still be able to access your camera or microphone even when these settings are turned off." This is not a certification failure (we declare webcam honestly and use supported APIs) but it is a real user-trust issue — so no privacy-forward marketing copy until it is measured. Guard note added to MARCOM.md.

⛔ Durable invariant: chat is rendered, never stored

TASK 49's profanity filter is local, on-device, opt-in, non-persistent, with a user-supplied word list — never a hardcoded slur list baked into the binary (unpleasant artifact, false positives across dialects, extractable). It must never match the SuperChat amount or any reward field — those are financial data under policy 10.5.5.

The non-persistence half is not just hygiene: it is the load-bearing half of the 11.12 UGC certification answer (mirrored YouTube chat is moderated at industrial scale upstream; ~1.6B comments removed in Q1 2026 alone, child safety the #2 reason at 124.6M). No future feature — chat history, moderation logs, analytics, crash payloads — may quietly break that assumption. If one is ever proposed, the 11.12 position must be re-argued first.

Minors

The operator is 13+ by construction, not by promise: LlamaCasty requires a YouTube account to stream, and YouTube's ToS sets the account floor at 13 (regional variants reach 14; 13–17 need parent/guardian permission; under-13s are on supervised/YouTube Kids accounts). So a COPPA theory premised on collecting PI from under-13s has no purchase against the operator. The residual is viewers — still possible on supervised family accounts — and it is weak: live chat is restricted there, YouTube moderates before we see it, and we persist nothing. COPPA is very unlikely to bind (not child-directed), but note the enforcement trend (FTC Sept 2025 Apitor: operators are responsible for what third-party components collect) — so the answer is a documented inquiry, and ours is "no third-party analytics or ad SDKs, no persisted chat or reward payloads."
