Squash-merge the cloudflare-migration branch (7 commits by Kai ki) into
staging with conflict resolution, feature integration, and bug fixes.
Engine:
- Paradigm D: single-stream Writer replacing dual-phase Plan/Beats
- Delete Architect agent; story bible generated via Writer <plan> tag
- Modular prompt architecture (segments/registry/builder)
- StreamRouter for tagged stream splitting (<plan>/<story>/<choices>)
Infrastructure:
- Cloudflare Workers deployment (wrangler.jsonc, OpenNext adapter)
- D1 database schema + Drizzle ORM (scaffolded, not yet active)
- R2 storage helpers (scaffolded, not yet active)
- Story persistence API routes + client-side persistence
BYOK (Bring Your Own Key):
- /api/llm/user-proxy with SSRF-protected LLM proxy (+ requireUser auth)
- CORS-aware fetch in ai-client: auto-detect CORS failure, fallback to
server proxy transparently via OpenAI SDK custom fetch
- BYO config support added to classify-freeform and vision routes
- SettingsModal CORS privacy notice (keys never logged/stored)
SSE streaming:
- engineClient.ts: fetchSSE helper for progressive scene events
- startSession/requestScene accept optional emit callback
- Fix SSE error event field name (error → message) in scene/start routes
i18n integration:
- Wire buildLanguageDirective into paradigm D's prompt builder
- Update corsNotice i18n keys (zh-CN/en/ja) with CORS proxy privacy text
- Preserve Session.language + LanguageSwitcher from i18n commit

Make homepage cards and live sessions produce sound when the server is
configured for StepFun TTS, instead of silently failing (the prebaked
Xiaomi voice was useless on a StepFun server, and wasted ~220KB/beat in
Fast Origin Transfer).
Three coordinated changes:
1. CharacterDesigner now picks a StepFun preset voice id directly from the
32-entry catalog in the SAME LLM call that designs the character — zero
extra latency, LLM-grade match quality. The Xiaomi prompt path is
byte-identical to history (verified programmatically) so cache hit rate
and voice quality are preserved. pickStepfunVoiceId (keyword scorer)
remains the fallback for orphan speakers / invalid LLM picks.
2. The 32-preset catalog moves to lib/tts-client/stepfun-voices.json as the
single source of truth, shared by the scorer, the CharacterDesigner
prompt, /api/tts-provider, and the offline enrich script.
3. A new GET /api/tts-provider endpoint lets the client probe the server's
TTS provider at /play mount. fetchBeatAudio then shapes its request body:
on a StepFun server it sends the lightweight stepfunVoiceId /
voiceDescription and omits the ~220KB Xiaomi reference audio (FOT saving
~13MB per protagonist per session on prebaked cards). requestBeatAudio
re-provisions on a provider mismatch before synth, so audio never goes
silent on a cross-provider replay or mid-session provider flip.
New type fields are all optional and backward-compatible: Character.stepfunVoiceId,
BeatAudioRequest.voiceDescription/characterName/stepfunVoiceId, voice made
optional. AGENTS.md updated for the new route, type fields, dependency map,
and StepFun voice-selection flow.
IMAGE_TIMEOUT_MS sets a per-attempt hard deadline (AbortSignal.timeout);
IMAGE_HEDGE_MS races a second identical scene-paint request when the
first is still pending past the threshold. Both default to OFF when
unset, preserving historical behavior for self-hosted deploys.

- Hash the lowercased description (matching the case-insensitive scoring)
so the same archetype text picks the same preset regardless of case.
- Thread the character name through provisionVoice -> stepfunProvision as
the hash salt, so two characters that share archetype keywords spread
across the top-N candidate presets instead of collapsing on one voice.
Xiaomi path is unaffected (voicedesign mints a unique clip per call).
Eliminate the dual code path (raw fetch vs AI SDK) for text and vision.
All providers now go through createLanguageModel() + generateText(),
removing chatOpenAiCompatible/analyzeOpenAiCompatible, the manual Usage
type, summarizeUsage, and responseFormat plumbing from 8 call sites.
Key fix: @ai-sdk/openai v3 defaults to the Responses API (/responses);
DeepSeek only supports Chat Completions, so we use .chat() explicitly.

Add a `tag` option to chat() and have it print one `[cache] <tag>
hit=X miss=Y rate=Z%` line per call. Three Usage-shape variants are
probed in order so the same logger works across providers:
- DeepSeek (v3+): usage.prompt_cache_hit_tokens / *_miss_tokens
- OpenAI / o-series: usage.prompt_tokens_details.cached_tokens
- Anthropic: usage.cache_read_input_tokens / *_creation_*
When none of them are present (MiMo / local Ollama / others) we still
print prompt + completion totals so the cost baseline is visible.
Tag every callsite so the log is greppable:
architect / writer / character-designer / cinematographer / insert-beat
This is the prerequisite for the prefix-cache reordering work that
follows — without per-agent visibility there's no way to tell if a
prompt rearrangement actually moved the needle.

Flatten the pnpm monorepo (apps/web + packages/*) into a single web package at the repo root.
- Move app/lib/components/scripts/public to root; drop apps/web and packages/* wrappers
- Rewrite tsconfig paths (@infiplot/*) to ./lib/*; turbopack.root = __dirname
- Update Vercel (no root-directory) and Cloudflare (pnpm build:cf at root) deploy paths
- Regenerate pnpm-lock.yaml to drop stale workspace importers
- Bump engines.node to >=22 to match wrangler
