Gittensory Orb is a separate, lightweight GitHub App (pull_requests:read + metadata:read) that records gate verdict + PR outcome (merged/closed) locally for calibration and optional aggregate telemetry. Nothing is sent without explicit ORB_ENABLED=true. - Setup wizard at GET /orb/setup — one-click GitHub App manifest flow creates the Orb App and writes credentials to /data/gittensory-orb.env - /orb/webhook handler — HMAC-SHA256 verified; handles pull_request.closed (records outcome + gate verdict from review_targets) and installation events (tracks which repos have the Orb App installed) - orb-collector.ts — local DB store (orb_events) + hourly export batch with HMAC-signed payload; ORB_ANONYMIZE=true (default) HMAC-hashes repo names; ORB_AIR_GAP=true keeps all data local - Migrations 0056 (orb_events) + 0057 (orb_installations) with UNIQUE constraints for idempotent event recording - Hourly export cron wired into server.ts; also flushes on startup - Grafana Orb row: recorded/exported/error/installs stats + event rate + pending vs exported timeseries (dashboard v3) - 56 tests across orb-collector, orb-setup, orb-webhook modules
…w selfhost modules - Fix TS2352 in selfhost-qdrant-vectorize.test.ts: all mock.calls[0] casts now use `as unknown as [...]` to satisfy the strict mock type - orb-collector: cover both sides of `GITHUB_WEBHOOK_SECRET ?? ""` (delete env var to trigger empty-string fallback) and `ORB_ANONYMIZE ?? "true"` (unset → defaults to anonymize=true) - orb-webhook: cover timingSafeEqual throw path (malformed hex sig → catch returns false), null closed_at/created_at (time_to_close_ms = null), repositories_removed ?? [] fallback, repositories ?? [] fallback on deleted event, and if(repos.length) false branch when install list is empty All five new src/selfhost modules now at 100% statements, branches, functions and lines.

…nt Host-header redirect attack Same class of vulnerability as the main setup wizard fix: the Orb wizard derived the manifest origin from PUBLIC_API_ORIGIN ?? request.url.origin, allowing an attacker to spoof the Host header and redirect the App-creation callback to an attacker-controlled domain to steal the Orb App credentials. Remove the request.url fallback from both setup wizards; return 400 when PUBLIC_API_ORIGIN is unset.

…rop AUTOINCREMENT from Orb migrations Use the Orb-specific env vars (ORB_WEBHOOK_SECRET, ORB_APP_ID) in exportOrbBatch and instanceId() instead of the main app's GITHUB_WEBHOOK_SECRET/GITHUB_APP_ID — prevents empty-string HMAC signing when only the Orb secret is set. Drop AUTOINCREMENT from orb_events/orb_installations DDL so the Postgres migration adapter accepts both tables (it translates INTEGER PRIMARY KEY but not AUTOINCREMENT).

The pg-dialect translator handles CURRENT_TIMESTAMP and strftime('%f') variants
but not strftime('%S', ...) — the Orb migrations used the latter, breaking the
Postgres integration test. Align with the existing migration convention.

Summary
Adds Gittensory Orb — a separate, lightweight GitHub App (read-only:
pull_requests:read+metadata:read) that records gate verdict + PR outcome locally for self-hosted calibration and opt-in aggregate telemetry. Completely off by default (ORB_ENABLED=false). Nothing leaves the instance without explicit opt-in.Architecture (inspired by entrius/das-github-mirror):
