Postgres stores only keys and metadata. - -Key layout (`app/services/storage.py::keys`): - -``` -ws/{workspace_id}/sources/{source_id}/documents/{document_id}/raw.html -ws/{workspace_id}/corpus/manifest.json path -> sha256 of every corpus file -ws/{workspace_id}/corpus/INDEX.md one line per post -ws/{workspace_id}/corpus/sources/{site}/{date}-{slug}.md clean post as markdown -ws/{workspace_id}/uploads/{upload_id}/{filename} -ws/{workspace_id}/artifacts/{artifact_id}/{variant}.{ext} audio, video, stills -ws/{workspace_id}/tts-cache/{sha256(script|voice|settings)}.mp3 -system/dspy/{module}/{version}.json compiled programs -``` - -Flows: - -1. **Server writes** (ingestion, TTS, compiled programs): worker calls `storage.put_bytes()`. -2. **Browser uploads** (logos, voice consent samples): `POST /api/storage/uploads` returns a presigned - PUT URL and an `upload_id`; the browser PUTs directly to R2; `POST /api/storage/uploads/{id}/complete` - verifies with a HEAD request and records size and content type. -3. **Renderer writes**: renderer receives a presigned PUT URL in the render request, so it never holds - R2 credentials. -4. **Reads**: `GET /api/storage/objects/{key}` checks workspace ownership and 302 redirects to a - presigned GET (default 1 hour). Public stills (quote cards) can later move to a public bucket with - a custom domain. - -The storage service is an S3 client with R2's endpoint, so MinIO in docker-compose stands in for R2 -locally with zero code changes. - -### 3.2 Research corpus: file system instead of embeddings - -Each post is one markdown file (front matter, `# Title`, `## Section` headings) and the workspace -has an `INDEX.md` with one line per post. Research is an agent loop (`dspy.ReAct`, -`app/pipeline/research.py`) with three tools scoped to the notebook's files (`app/corpus.py`): - -| Tool | Does | -| --- | --- | -| `list_files(contains)` | Index lines for the notebook's posts: date, path, title, headings | -| `search(pattern, path)` | Case insensitive regex grep, returns `path:line: text` | -| `read(path, start_line, end_line)` | Numbered lines, 160 per call | - -The model searches with several phrasings, reads around the hits, and answers with citations of -the form `(path, line_start, line_end)`. Before anything reaches the writer, every citation is read -back from the file: citations that point outside the notebook, past the end of a file or at empty -lines are dropped, markers are renumbered, and an answer left with no verified citation is replaced -by "not in your posts". The UI streams each step ("Searching for pricing|paid tier", "Reading On -pricing, lines 1 to 40"). - -Why this over embeddings: -- One vendor. Z.ai's international API has no embedding model, and there is no second key, - re-embedding job or dimension lock-in. -- Citations are exact line ranges the model actually read, which is stronger grounding than - nearest-neighbour chunks. -- Writers' archives are small (hundreds to a few thousand posts, a few MB of text), so grep over - local files takes milliseconds. -- The corpus is plain markdown, so the same files feed podcast scripts, launch kits and a future - MCP server without conversion. - -Trade offs: each question costs several LLM steps instead of one (mitigated by -`LLM_REASONING_EFFORT=low` and the `RESEARCH_MAX_STEPS` cap), and paraphrase matching depends on -the model trying synonyms. If quality or latency needs it later, a Postgres full text index can be -added as a fourth tool without changing the corpus. - -Storage and sync: R2 holds the corpus under `ws/{id}/corpus/` with a `manifest.json` of file hashes. -The worker writes files to R2 and its own cache in one pass. The API calls `Corpus.sync()` before -each research run, which reads the manifest and downloads only changed files into -`CORPUS_CACHE_DIR`. Containers share nothing but R2. - -Brief items that assumed embeddings: voice similarity uses the LLM judge alone; the topic map is -built from LLM extracted entities per post (Phase 2); resurfacing and SEO internal links search the -corpus with the same tools. - -### 3.3 LLM layer - -`app/llm/provider.py` builds a `dspy.LM` from env: - -``` -LLM_MODEL=openai/glm-5.3 # any LiteLLM model string -LLM_FAST_MODEL=openai/glm-5.3-flash # judges, cleanup, cheap passes -LLM_API_BASE=https://api.z.ai/api/paas/v4 -LLM_API_KEY=... -LLM_REASONING_EFFORT=low # low | high | max -``` - -Z.ai considerations baked in: -- OpenAI compatible chat endpoint, so the `openai/` LiteLLM prefix plus `api_base` works. -- GLM-5.x always reasons (thinking cannot be disabled). Every call sends `thinking: enabled` with - `reasoning_effort=low` by default; modules that benefit (the groundedness judge) ask for - `main_lm("high")`. Reasoning tokens count against `max_tokens`, so the default is 16K to leave - room for the structured answer. Z.ai recommends temperature 1.0 for GLM-5.x. -- 1M token context on GLM-5.3 means whole-notebook prompts (summaries, podcast scripts) can read - the files directly; chat uses the research agent to keep citations tight and cost low. -- Tool calling runs through DSPy ReAct, so it works with any provider, not only ones with native - function calling. -- Token usage from every call is written to `usage_events` (metering from day one). - -Swapping to Anthropic, OpenAI, Gemini or a local model is only an env change. - -### 3.4 Jobs and progress (Postgres, no Redis) - -The `jobs` table is the queue, the progress record and the SSE source. - -- **Enqueue:** the API inserts a `queued` row (`create_job`). Nothing else. -- **Claim:** `python -m app.worker` polls every `WORKER_POLL_SECONDS` and takes the oldest runnable - row with `SELECT ... FOR UPDATE SKIP LOCKED`, so any number of workers can share the table without - double running a job. Up to `WORKER_CONCURRENCY` jobs run at once in threads. -- **Retry:** a handler that raises is requeued with backoff (30s, 60s, 120s... capped at 15 min) - until `max_attempts` (default 3), then marked `failed`. -- **Heartbeat:** every progress update stamps `heartbeat_at`. A `running` job silent for - `JOB_STALE_SECONDS` (worker crashed, renderer died) is requeued by the stale sweeper. -- **Hand off:** render jobs return `HANDED_OFF`; the renderer's progress callbacks keep the row - alive and mark it done. -- **Progress to the browser:** `GET /api/jobs/{id}/events` re-reads the row about once a second and - sends only changes. Latency is at most a second, which is fine for progress bars. -- **Schedules:** the worker runs the stale sweep (1 min), update email batch (5 min, gated to the - campaign send hour) and daily cleanup. Each takes a Postgres advisory lock, so with several - workers only one runs a given task. - -No request blocks for more than a few seconds. Add Redis back only if job volume makes polling a -measurable load on Postgres; the handler code would not change. - -## 4. Data model - -Implemented in `backend/app/models` and `alembic/versions/0001_initial.py`. - -- users, workspaces, workspace_members, subscriptions -- email_verification_codes, update_emails, update_email_sends -- sources, documents (with corpus `path`), notebooks, notebook_documents -- voice_profiles, voice_consents -- chats, messages, citations (document, path, line range, verified quote) -- artifacts, jobs (covers render_jobs and tts_jobs via `kind`), uploads -- calendar_items, tracked_links, engagement_events -- dspy_traces, usage_events - -## 5. DSPy program design - -See brief Section 6. Signatures live in `backend/app/llm/signatures.py` with Pydantic output models. -Phase 1 ships CleanAndSegment, ResearchArchive (the file research agent) and BuildVoiceProfile. All grounded outputs cite `SourceRef(path, line_start, line_end)`. The rest are stubs with typed -signatures so the schema contract is fixed early. - -## 6. Plans - -| | Free | Writer | Studio | -| --- | --- | --- | --- | -| Price (when billing turns on) | $0 | $24.99/mo ($18.99/mo billed annually) | $48.99/mo ($36.99/mo billed annually) | -| Sources | 1 | 3 | 10 | -| Indexed posts | 5 | 500 | 5,000 | -| Audio overview minutes / mo | 3 | 60 | 240 | -| Video render minutes / mo | 1 | 30 | 120 | -| Launch Kits / mo | 2 | 50 | unlimited | -| Voice profile | yes | yes | yes | -| Voice cloning (with consent) | no | yes | yes | -| Brand kit, no watermark | no | yes | yes | - -While `BILLING_ENABLED=false`, every workspace resolves to Studio limits. - -## 7. Design system - -Strict palette: `#000000`, `#217cff`, `#FFFFFF` and opacity variants only. Tokens in -`frontend/src/styles/tokens.css`. Landing page is a night sky: canvas starfield with slow parallax, -small twinkling sparkles, a soft blue nebula haze and a neon horizon line. `prefers-reduced-motion` -renders a static sky. Logo slot (``) is a white tile that holds the black silhouette mark; -drop the final file at `frontend/public/logo.svg`. - -Copy rule: no em dashes anywhere in UI, email or generated output.
