title: Roadmap updated: 2026-03-26 #

API: Search Stabilization #

Highest priority. This work blocks further investment in search quality and broader discovery features.

• Stabilize local development around PostgreSQL, with SQLite kept only as a rollback path
• Document backup, restore, and disk-growth procedures for the experimental local DB
• Research production backend options: PostgreSQL, Turso remote/libSQL, and Turso embedded replicas
• Write a production storage decision record with workload and operational tradeoffs, using docs/adr/pg.md and docs/adr/turso.md
• Define the migration path from the experimental local setup to the chosen production backend
• Add a durable read-through indexing job queue for records fetched through the API
• Add API smoke tests for healthz, readyz, search, documents, indexing, and activity in packages/scripts/api/
  • desertthunder.dev DID: did:plc:xg2vq45muivyy3xwatcehspu
  • Twisted AT URI: at://did:plc:xg2vq45muivyy3xwatcehspu/sh.tangled.repo/3mho6hukiei22
  • Profile AT URI: at://did:plc:xg2vq45muivyy3xwatcehspu/sh.tangled.actor.profile/self
  • Follow AT URI (desertthunder.dev follows npmx): at://did:plc:xg2vq45muivyy3xwatcehspu/sh.tangled.graph.follow/3mhofstanru22
  • Star AT URI (desertthunder.dev stars microcosm-rs): at://did:plc:lulmyldiq4sb2ikags5sfb25/sh.tangled.repo/3lvsxzinfz222
• Add just targets for smoke-test runs locally and against a remote base URL directly invoking the scripts is fine.
• Reuse the existing normalization and upsert path for on-demand indexing jobs
• Trigger indexing jobs from repo, issue, PR, profile, and similar fetch handlers
• Add dedupe, retries, and observability for indexing jobs
• Add a JetStream cache consumer with a persisted timestamp cursor
• Seed the JetStream cursor to now - 24h on first boot and rewind slightly on reconnect
• Store and serve bounded recent activity from the local cache
• Keep Tap as the authoritative indexing and bulk backfill path
• Define a controlled backfill and repo-resync playbook for recovery (docs/reference/resync.md)

API: Constellation Integration #

Completed on 2026-03-25

API: Keyword Search Quality #

Improve keyword search quality without external dependencies.

Depends on: API: Search Stabilization

• Synonym expansion at query time (e.g. "repo" matches "repository")
• Stemming and parser tuning for PostgreSQL full-text search
• Prefix search support for autocomplete
• Field weight tuning based on real query patterns
• Recency boost for recently updated content
• Star count ranking signal (via Constellation)
• State filtering defaults (exclude closed issues)
• Better snippets with longer context
• Relevance test fixtures

API: Observability #

Depends on: API: Search Stabilization

• Structured metrics: ingestion rate, search latency, embedding throughput
• Dashboard or log-based monitoring

API: Embedding Adapter #

Depends on: API: Search Stabilization

• Add an embedding provider interface in the API
• Add a llama.cpp HTTP adapter targeting llama-embeddings
• Add PostgreSQL embedding schema and jobs using pgvector
• Define source-code chunking and repo re-embed triggers
• Add embed and reembed operational commands
• Add queue-depth, latency, and throughput metrics for embeddings
• Keep semantic or hybrid retrieval behind a non-default search mode

App: Search & Discovery #

Wire the Explore tab to the search API and add activity feed.

Depends on: API: Constellation Integration

• Search service pointing at Twister API
• Constellation service for star/follower counts
• Debounced search on Explore tab with segmented results
• Recent search history (local)
• Graceful fallback when search API unavailable
• Activity feed data source investigation (Jetstream vs polling)
• Activity tab with filters, infinite scroll, pull-to-refresh
• Home tab: surface recently viewed repos/profiles

App: Authentication & Social #

Bluesky OAuth and authenticated actions.

Depends on: App: Search & Discovery (for Constellation service), API: Constellation Integration

• OAuth setup with @atcute/oauth-browser-client
• Login page, OAuth flow, callback handling
• Capacitor deep link configuration
• Session management (restore, refresh, logout, account switcher)
• Auth-aware XRPC client using dpopFetch
• Star repos (write to PDS, count from Constellation)
• Follow users (write to PDS, count from Constellation)
• React to content (write to PDS, count from Constellation)
• Authenticated profile tab (pinned repos, stats, starred, following)
• Personalized feed ("For You" / "Global" toggle)

App: Write Features #

Depends on: App: Authentication & Social

• Create issue (title + markdown body)
• Comment on issues and PRs (threaded)
• Close/reopen issues
• Edit profile (bio, links, avatar, pinned repos)
• OAuth scope upgrade flow

App: Offline & Performance #

Depends on: App: Search & Discovery (for cache persistence of search/feed data)

• IndexedDB-backed local cache and bookmark storage for first release
• Migrate offline cache and saved-content storage from IndexedDB to SQLite
• TanStack Query persister backed by SQLite or equivalent app-managed store
• Pinned content store (save/unsave files for offline reading)
• Pinned files UI (list, pin/unpin actions on file viewer, last-fetched timestamp)
• Offline detection and banner
• Migrate auth/session data to Ionic secure storage
• Cache eviction (per-type limits and TTL, pinned content exempt)
• List virtualization for large datasets
• Lazy-load avatars, prefetch on hover
• Code splitting and bundle optimization (target <500KB JS)

App: Real-Time & Advanced #

Depends on: App: Authentication & Social, App: Offline & Performance

• Jetstream integration for live sh.tangled.* events
• Live UI indicators (new commits, new feed items, PR status)
• Custom feed presets ("My repos", "Watching", "Team")
• Repo forking
• Labels (display, filter, manage)
• Expanded reactions with emoji picker
• PR interdiff (compare rounds)
• Knot info display

App: Push Notifications #

Depends on: App: Authentication & Social

• Register device token on login
• Subscribe to relevant events
• Deliver via APNs/FCM
• Handle notification taps (deep link to relevant screen)
