Reference implementation; GitLab and Linear follow in separate PRs.
Issue observer loop (poll + ApplyTrackerFacts) is deferred to #35.
Three-layer split mirrors the SCM layout adil is landing in PR #28:
- domain/tracker.go — value types (TrackerProvider, TrackerID,
NormalizedIssueState, Issue)
- ports/tracker.go — the Tracker interface
- adapters/tracker/github/ — REST-backed adapter
v1 is write-mostly: Get, Comment, Transition. No cache, no inflight
dedup, no polling. State mapping is documented in the package doc and
exercised by table-driven tests against an httptest fake — no real
GitHub traffic from CI.
