TASK 5 items 1-3: reusable stream, health banner, docs refresh

- Reusable stream: GetOrCreateReusableStreamAsync, cached via LayoutStore, bound at broadcast insert
- Health monitoring: GetStreamHealthAsync polls liveStreams.status, report-by-exception banner
- Go-live order: ensure stream → create broadcast → then start pump (URL must exist first)
- Full broadcast form scoped (TASK 5 items 6-7) in TASKS.md + ai.md
- TASK 23 trimmed to technical scope, TASK 26 added (marcom/launch kit)
- Confidential files: MONETIZATION.md + MARCOM.md (gitignored, not committed)
- .gitignore updated for confidential business files
- HANDOFF.md updated with session state and next steps

+1. ☑ **Broadcast creation** — title/description/privacy/scheduledStartTime via API, with the v3 flags above (SHIPPED: `CreateBroadcast` sends `enableAutoStart/Stop`, `enableMonitorStream=false`, `latencyPreference=low`, `selfDeclaredMadeForKids=false`)
+2. ☑ **Reusable stream** — create once, cache + reuse; bind to broadcast (SHIPPED: `GetOrCreateReusableStreamAsync` lists-then-inserts the `variable`/`isReusable` stream, cached via `LayoutStore` Settings, bound at broadcast insert via `boundStreamId`; `_rtmpUrlProvider` yields the ingest URL so go-live actually encodes + pushes)
+3. ☑ **Health monitoring** — poll `liveStreams.list` `healthStatus` + `configurationIssues[]`, surface banner only on warning/error (SHIPPED: `GetStreamHealthAsync(streamId)` 30s while live; pure `StreamHealthReporter.BannerFor` = report-by-exception; banner strip under the top bar, amber warning / dark-red error, via `HealthIssueBanner`/`HealthIssueBackground`; poll failures log-only; ONE integration test `GetStreamHealthAsync_Report_By_Exception_Banner_Only_On_Warning_Or_Error`)
 4. ☐ Live chat — poll `liveChat/messages`, render in right panel, support Super Chat + membership badges
 5. ☐ Error handling — the YouTube error codes: `errorStreamInactive`, `invalidTransition`, `redundantTransition`, `liveStreamDeletionNotAllowed`, `liveStreamModificationNotAllowed`, `liveBroadcastBindingNotAllowed`
+6. ☐ **Visibility picker** — remove temporary "always Private" enforcement (shipped as test-only; now unlocked for v1). User picks Private/Unlisted/Public from the go-live dialog. Trivial: remove the hardcoded override in `YouTubeStreamService.CreateBroadcast` (currently `privacyStatus = "private"` regardless of dialog selection)
+7. ☐ **Full broadcast form** — expose all YouTube API-supported fields in the go-live dialog. Core tab: title, description, visibility, made-for-kids, schedule (start + optional end). Advanced tab (expandable, sane defaults): latency (Normal/Low/Ultra-Low), DVR, embed, record-from-start, projection (rectangular/360°), closed captions, auto-start, auto-stop, monitor stream, region restrictions. Monetization via `liveBroadcasts.update` (insert-only on that resource) — separate step after broadcast creation. Remove unsupported `categoryId` (not a `liveBroadcast` field, silently ignored)

-**Decisions already locked (2026-08-14, creator):** one paid line = **annual subscription** (early
-access **$49.99/yr** → **$99/yr list at GA**; grandfather-while-subscribed, lapse → list on renewal;
-no escalation matrix). Free tier unchanged (branding flash + no Alerts; the flash is the free tier's

+### Status: 🔶 Scoped — nothing built
 
-1. ☐ **Billing provider decision** — Gumroad vs Lemon Squeezy (annual subs + license-key verification
-   APIs; Gumroad's native affiliate program is the tiebreaker if the TASK 23 affiliate line-item matters)
-2. ☐ **Unlock mechanism** — license-key entry + online/offline verification + persisted entitlement
-   (extends `LayoutStore`, schema bump) + renewal/lapse handling (**lapse → branding flash returns** —
-   the flash is the enforcement and the billboard)
-3. ☐ **In-app bug-report → git issues** — a built-in report control that files an issue (title/body/
-   log attachment) into the creator's git repo; the support loop, per the settled support model
-4. ☐ **"Unlock Premium" seam** — the About hub's greyed button (TASK 21; `PremiumUrl` is the tabled
-   billing URL) lights up and routes to the billing page / unlock dialog
-5. ☐ **Alerts gating** — the Super Chat pop-ins (TASK 3 item 18 / minimal source set item 7) are the
-   one paid feature; subscription state gates them
-6. **Line-item pointers (their own big tasks — do NOT start here):**
-   - ☐ **Early-access strategy** — the 90-day funnel (founder window $49.99 → GA $99), waitlist,
-     testimonials/QA, clips → Shorts. Separate planning effort.
-   - ☐ **Affiliate & ads (phase 2)** — own-channel gear affiliates from day one (organic), a
-     ytLlive referral program gated behind GA + happy users, YPP as the channel's ad revenue, paid
-     ads deferred.
-   - ☐ **Channel revival (the prequel to both)** — **resume streaming**: pair-programming dev
-     streams via **OBS** (ytLlive can't go live yet — private-only + `_rtmpUrlProvider` null) +
-     **The Division 2** gaming streams under the **"gramps/GOAT"** persona (67, gaming since 1981).
-     3D-printing content retired (printer hard down, novelty gone). **Dogfood switch** — once TASK 5 +
-     go-live capability land, stream *with* ytLlive; Division 2 (loud game + voice) is the demo for the
-     ducking/voice-filter story. The flash billboard + the grandfather promise are the monetization
-     hooks this line-item feeds.
