The Sink port carries only a Summary, so video title/url/published_at would never reach the store. UpsertVideo (new file, store.go untouched) persists them and returns the durable videos.id UUID, idempotent on (user_id, provider, provider_video_id). The run loop uses that id as v.ID, so it equals summaries.video_id and SeenVideoIDs dedup survives restarts. subscription_id stays NULL: the YouTube resource id is not a UUID (Stage 0).

tapir
Watches a user's YouTube/Vimeo subscriptions and, when a subscribed channel posts a new video, summarizes it into highlights and takeaways using a local-first AI stack with an optional, per-user BYO-AI fallback. Standalone-first; feeding a personal knowledge base ("brain") is one optional sink, not the reason Tapir exists. Written in Go.
Status
Pre-code. The repository currently holds the guardrail documentation — vision, decisions, architecture, data model, and behavior specs — committed before implementation so the design intent is version-controlled and the build has something to be checked against.
Read these first (the guardrails)
| Doc | What it is |
|---|---|
VISION.md |
Product vision, principles, and the staged Definition of Success. Stage 0 ("useful to me") is the gate before any multi-user work. |
DECISIONS.md |
Architecture Decision Records (append-only). Why Go, why no Supabase, standalone-first, captions-first, etc. |
docs/architecture/architecture.md |
C4 context + container diagrams, key sequence diagrams, and the Clean Architecture layering (Mermaid). |
docs/data-model.md |
Entities and the per-user isolation model (Stage 0 / Stage 1 scope). |
docs/use-cases/ |
Gherkin .feature files — the BDD behavior spec that seeds the test suite. |
Approach
- Clean Architecture / ports & adapters. A provider- and sink-agnostic engine depends only
on interfaces (
VideoSource,Summarizer,Sink,SecretStore). YouTube, Vimeo, the AI router, the user store, and the brain sink are adapters. "Standalone vs homelab" is a wiring choice, not two codebases. - TDD/BDD. The
.featurefiles are the living behavior spec; the use-case core is tested through fake adapters. Behavior is specified as executable scenarios, not prose that drifts. - Trunk-Based Development. Commit directly to
main, one logical change per commit, every commit deployable (see ADR-009). CI is the quality gate.
Conventions
Reuses homelab conventions: Go, Dex for identity, ESO + 1Password for secrets, Postgres for persistence. No new auth or secrets system (ADR-002).
Next
First implementation step: scaffold the Go service (engine + interfaces + the copied llm
package), captions-first, with the store and brain sink adapters — decomposable into
independent units suitable for a Claude Code swarm. Tracked as the first build issue.
