fix(hub): single-owner httpServer construction in NewHub (closes 187) (#188)
TigerStyle: eliminate the shared mutable state instead of guarding it. Move mux + http.Server construction from ServeHTTP into NewHub. After NewHub returns, h.httpServer and h.httpListener are immutable for the hubs lifetime — single writer (NewHub), many readers (ServeHTTP, Stop). No mutex, no atomic, no sync.Once required: the race is gone by construction. Add a hub package-private assert helper and positive invariants at entry to ServeHTTP and Stop, surfacing programmer-bugs loudly instead of silently UB-ing on a nil httpServer. Fixes the 3 data races in TestCrossSessionAutosync and the 3 in TestScope_Project_ConcurrentCommits under -race; hub package suite green at -race -count=3.

fix(hub): resolve TestNotifyCLIPairAndDevices flake (closes #170) (#186)
* fix(hub): resolve TestNotifyCLIPairAndDevices flake (closes #170) Each of the 4 tests in cmd/edgesync/notify_test.go independently invoked `go build` for the edgesync binary inside its own body. Under cold build cache or parallel test load, this build storm pushed the package's total runtime past `go test -short -timeout=30s ./...` (the pre-push hook gate) and the suite-level timeout fired — surfacing as a hang on os/exec.Wait since the inner `go build` child was still running when the supervisor killed the test process. Move the build into TestMain so the binary is built once and reused. With -timeout=30s on cold cache, cmd/edgesync drops from ~9s to ~3s and the target test from ~2.8s to ~0.07s — comfortably clear of the timeout. No production-code change. No sleep band-aids. Verified 200/200 passes (50× per test in the package) and 80/80 under -race. * fix(test): clean up temp dir before os.Exit (Ousterhout follow-up to PR 186) --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> check-in: 37780572c3 user: [email protected] tags: trunk, main | |

feat(hub): Hub.EnsureUser — idempotent user-table registration (closes #183) (#184)
Add Hub.EnsureUser(login, caps string) error as an idempotent counterpart to Hub.AddUser. Consumers (sesh, others) need "register if absent" semantics; AddUser errors on duplicate, forcing each consumer to write check-then-act + race-recheck wrappers. The user-table layer is the right place to own that idempotency. Implementation choice (a) — GetUser → CreateUser, serialized by a Repo- level mutex. Picked over (b) "catch CreateUser's already-exists error" because libfossil's CreateUser surfaces a wrapped SQLite UNIQUE-constraint error with no sentinel or typed shape — string-matching would be brittle. A defensive GetUser retry after CreateUser failure absorbs the rare cross- process race where the in-process mutex doesn't apply. Contract: existing caps are PRESERVED on duplicate (documented). Callers wanting replace-on-conflict use SetUserCaps explicitly. Tests cover first-time registration, duplicate no-op, caps-change-on- duplicate (preservation), 5-goroutine concurrent race (exactly one row lands), and empty-login rejection. Full hub package + leaf + bridge + CLI suites pass; go vet clean; gofmt clean.
