docs(lessons): explain current state only; rename API title to 'Script Studio'#182

Conversation
Per the updated framing, the teaching series should describe the system as it is today — design decisions, architecture, tools, and how they work — without narrating prior versions. Also aligns the API metadata with the public-facing 'Script Studio' rename. Lessons touched - 01 Why This System Exists: drop the V1→V2 change table; refresh the product description to today's artifact (ten short-form video scripts, 42 personas, 260 LLM calls). - 02 Deployed Architecture: drop the 'Gemini → Kimi' and 'OpenAI → Anthropic' migration narratives; keep the current Kimi wiring and the docs-drift meta-point. - 14 Provider Abstraction: reframe around why the ReasoningProvider Protocol shape exists today (domain-dictated interface, churn confinement). Remove the 'payoff story' narrating the past swap. - 15 Kimi chapter: rewrite from 'two-migrations' arc into 'how the Kimi provider is wired today' — Anthropic Messages API endpoint, base_url quirks, UA allowlist, content-block responses, lazy client, retry separation. - 23 Frontend Stack: drop the 'V1 design language PR narrative', explain the current design-tokens / Tailwind split instead. Keep the crypto.randomUUID fallback with the actual fallback code. - README: update the lesson 15 index row to match the new title. Backend - backend/app/main.py: rename FastAPI title from 'AI Campaign Studio' to 'AI Script Studio' so the OpenAPI metadata (shown at /docs) matches the product rename already applied to the frontend and deck. Verification - backend: 157 passed, 32 skipped; ruff clean on app/main.py. - grep: no 'Campaign Studio' or V1/V2 comparison phrases remain in backend/ or docs/lessons/.

Pull request overview
Updates the Flair2 teaching series to describe the system strictly in its current (April 2026) state, and aligns the backend FastAPI OpenAPI metadata with the shipped “Script Studio” product rename.
Changes:
- Rewrites multiple lessons to remove V1/V2 migration narratives and focus on current architecture, tooling, and provider wiring.
- Renames the FastAPI app title from “AI Campaign Studio” to “AI Script Studio” (impacts
/docsand OpenAPI spec). - Updates the lessons index row for lesson 15 to match its new framing/title.

| The docstring on the provider file calls this out for anyone reading the code cold: | ||
|
|
||
| ```python | ||
| """Kimi (Moonshot AI) reasoning provider via the Anthropic Messages API. | ||
|
|
||
| Kimi's coding endpoint migrated to an Anthropic-compatible schema | ||
| (see /coding/v1/messages). The legacy OpenAI /chat/completions shim | ||
| now returns a misleading "only 0.6 is allowed for this model" error | ||
| for every request, regardless of temperature — a dead surface. | ||
| Kimi's coding endpoint uses an Anthropic-compatible schema | ||
| (see /coding/v1/messages). Requires a coding-agent User-Agent | ||
| on the allowlist, or the endpoint returns 403. | ||
| """ |

The lesson says “The docstring on the provider file calls this out…” and then quotes a docstring that mentions the UA allowlist requirement. In the current backend/app/providers/kimi.py docstring (lines 1–7), it instead discusses the legacy OpenAI /chat/completions shim and doesn’t mention the UA allowlist at all. Please update this quoted docstring (and/or the real provider docstring) so the lesson matches the repository’s actual current-state documentation.

| ## The `crypto.randomUUID` fallback | ||
|
|
||
| ## The `crypto.randomUUID` fix (PR #121) | ||
| The frontend generates client-side session IDs with `crypto.randomUUID()`. That API is only available in **secure contexts** (HTTPS or `localhost`). S3 static website hosting serves over plain HTTP unless you put CloudFront in front of it — so on the deployed site, `crypto.randomUUID` is `undefined`. | ||
|
|
||
| A fun edge case: the frontend used `crypto.randomUUID()` to generate session IDs. This API is only available in **secure contexts** (HTTPS or localhost). S3 static website hosting serves over HTTP, not HTTPS (unless you add CloudFront). On HTTP, `crypto.randomUUID()` is undefined. | ||
| The client-side code guards for that: | ||
|
|
||
| PR #121 added a fallback: check if `crypto.randomUUID` exists, and if not, generate a UUID using `Math.random()`. This is less cryptographically secure but sufficient for session IDs in a prototype. | ||
| ```typescript | ||
| function generateSessionId(): string { | ||
| if (typeof crypto !== "undefined" && crypto.randomUUID) { | ||
| return crypto.randomUUID(); | ||
| } | ||
| // Fallback for non-secure contexts (S3 over HTTP) | ||
| return "sess_" + Math.random().toString(36).slice(2) + Date.now().toString(36); | ||
| } | ||
| ``` |

The crypto.randomUUID section shows a generateSessionId() implementation that doesn’t match the actual code in frontend/src/lib/api-client.ts (getSessionId() persists to localStorage and uses crypto.randomUUID?.() + a Math.random()+Date.now() fallback without the sess_ prefix). Since this lesson claims to show the real deployed fix, please update the code block and surrounding description to mirror the current implementation (including the SESSION_KEY/persistence behavior).
