Travis Herbranson c92a40bce1 web: dashboard + settings editor (HTMX save) + pipeline observability 
Adds three new routes on the FastAPI web app:
- GET  /dashboard        — pipeline counts by status (per-status drill-down
                           via filtered /?status=… links), recent activity
                           (latest 10 sources), and a settings snapshot
                           card with an "edit →" shortcut.
- GET  /settings         — full editing form for pipeline_settings.
- POST /settings/save    — HTMX endpoint that validates the partial form,
                           upserts the row, and returns the rerendered
                           card with a "Saved." or error flash. The card
                           is its own _settings_card.html partial so the
                           HTMX swap targets only the form region.

Form parsing lives in settings_store helpers (parse_time_or_none,
parse_int_or_none) — keeps the route thin and the empty-string-to-NULL
normalisation in one place. Validation rejects negative counts and
sub-1 GPU concurrency.

The base template grew a Dashboard + Settings nav so the new routes are
reachable without typing URLs. Added python-multipart to deps because
FastAPI's Form(...) raises at app import without it.

README.md

second-brain

A personal knowledge system built on a video/article extraction pipeline and an LLM-maintained wiki (inspired by the Karpathy LLM Wiki pattern).

What it does

  1. Pull — download YouTube videos or fetch web articles
  2. Transcribe — extract transcripts via Whisper (videos) or trafilatura (articles)
  3. Extract — single-shot Claude call produces structured notes per source
  4. Review — web UI to accept or reject extractions
  5. Compile — wiki compiler folds accepted extractions into a living Obsidian vault

Quick start

# Install dependencies
uv sync

# Copy and edit config
cp config/settings.toml config/settings.local.toml

# Queue a source
uv run second-brain add https://www.youtube.com/watch?v=...

# Run the pipeline
uv run second-brain process

# Review in the web UI
uv run second-brain serve

# Compile to wiki
uv run second-brain compile

Domains

Extractions are tagged by domain so the right prompt template is used:

Domain Focus
development Software, programming, systems
content Content creation, video production
business Entrepreneurship, marketing, ops
homelab Self-hosted infra, networking, DevOps

Extractor backends

Two backends, selectable via [extractor].backend in config/settings.toml:

  • cli (default) — shells out to claude -p --output-format json --json-schema .... Runs under your Max OAuth subscription, no per-token billing. The wrapper spawns the CLI in a throwaway tempfile.TemporaryDirectory and strips ANTHROPIC_API_KEY / ANTHROPIC_AUTH_TOKEN from the env so host CLAUDE.md, hooks, and settings don't leak in, and the subscription is used instead of the API key.
  • api — uses the anthropic Python SDK, requires ANTHROPIC_API_KEY. Install with uv sync --extra api (the SDK is an optional dependency).

Requirements

  • Python 3.12+
  • Either the claude CLI on PATH (default backend) or ANTHROPIC_API_KEY (api backend)
  • ffmpeg (for Whisper audio extraction)

In-flight work

  • Postgres + pgvector migration — SQLite is the current backing store but the project is moving to Travis's Postgres instance. Planning questions live in postgres-migration-planning.md; nothing has been migrated yet.
