 | Task | Date | Status | Gate runs | First gate | Deviations | Notes | Model |
 |---|---|---|---|---|---|---|---|
+| v1/07-main | 2026-09-25 | done | 1 | pass | none | Wired store, limiter and lease table into `cmd/crossbar/main.go`: `store.Open` before the health table, `limiter.Configure` per (host, model) from `cfg.Hosts`, `lease.New` with `proxy.Chooser`, `Candidates` for every route, three background goroutines (idle expiry per minute, prune per hour logging the count, host-health recording per `poll_interval`), and `st.Close` via `defer`. The 3s SIGTERM run exits 0 with `listening`/`shutting down`; the missing-config run exits 1. | ? |
 | v1/06-admin | 2026-09-25 | done | 2 | fail | Split `internal/admin/admin.go` (196 lines) + `admin_ops.go` (366 lines) to stay under 400. Updated `cmd/crossbar/main.go`'s `admin.Handler` call from the committed 2-arg `(cfg, table)` to the task's 6-arg signature, passing the health table for `hosts` and `nil` for the not-yet-wired `leases`/`limiter`/`store`/`drainer` (task 07 wires them); this was a compile fix required for `go vet`/`go test ./...` on `cmd/crossbar` to pass — the full wiring is task 07. | First `make gate` failed on `go vet` (`admin.Handler` called with 2 args in `main.go` after the signature changed); fixed `main.go` and the gate passed on the second run. `admin_test.go` and `example.toml` verified byte-identical to `docs/plans/v1/_files/`; `internal/lease` and `internal/store` left untouched except the already-present `Candidates`/`StatusCounts`. | ? |
 | v1/05-proxy | 2026-09-25 | done | 2 | fail | Split `internal/proxy/proxy.go` (411 lines) into `proxy.go` + `forward.go` by moving `forward`, `newReverseProxy`, `forwardState`, `statusRecorder`, `leaseState`, `ttfbMs` and the `writeError`/`writeRecord` helpers to `forward.go`; the one `recorder_test.go` `proxy.New` call changed to `proxy.New(cfg, h, nil, nil, nil, nil)` per the task; `cmd/crossbar/main.go` passes `nil, nil, nil` for the new `leases`/`lim`/`rec` args (task 06 wires them). | The tee in `tee.go` already read the final SSE chunk's (streamed) and the JSON body's (non-streamed) usage/timings, so `TestAccountingRowsFromUsageAndTimings` passed on the first run — the only gate blocker was `proxy.go` at 411 lines. | ? |
 | v1/04-lease | 2026-09-25 | done | 1 | pass | The given `TestPinAndUnpin` was wrong and replaced by the owner mid-task; the corrected `internal/lease/lease_test.go` is byte-identical to `docs/plans/v1/_files/internal/lease/lease_test.go`. A `fmt.Printf("DEBUG …")` line the prior session left in `event` was removed before the gate. | `Acquire` order (pinned, existing, inherit, choose) with memory rolled back only after a successful save; `Pin` writes a pin event, then the pin row, then deletes other-host leases, so the pin event always precedes the unpin's release event in the log. | ? |
