 |---|---|---|---|---|---|---|---|
+| v2.2/01-route-templates | 2026-09-25 | done | 1 | fail | `internal/config` red only on `Wake.Addresses()` (task 02), the one allowed red; `go build ./...` clean, proxy/admin/health/wake/lease/store/identity/fingerprint all pass under `-race`. New `internal/config/route.go`: `templateName` pattern `^[a-z0-9][a-z0-9-]*-\*$` and `Route()` (valid-name guard excludes `*`; exact wins; else longest `"<prefix>-*"`, prefix keeps the dash, non-empty remainder required, longest-prefix wins deterministically). `config.go`: the route-name check accepts a template too (one line). `proxy.go`: `route()` and `ServeHTTP` resolve both path and `X-Crossbar-Route` header forms through `cfg.Route`, and the conflicting-route check compares concrete names via `cfg.Route` (identical to before for non-template configs). `admin.go` `routeView` lists a lease under the exact key it matches or the longest template key; `admin_ops.go` `routePin` resolves through `cfg.Route` so a concrete route under a template can be pinned before its first request and the template name 404s. `main.go` identity lookup uses `cfg.Route`. All three given tests byte-identical (`config_v22_test.go` keeps `TestWakeBroadcasts`, which is why config is red). | ? |
 | v2.1/02-props-loaded-only | 2026-09-25 | done | 1 | pass | `movedHeader` separator `><`→`>` and the `CtxHeader` doc comment in `proxy.go`, both forced by the given router test (`moved:small>big`) which the task text did not mention; no production code parses the separator (`forward.go` passes it straight through) so it is safe. | Implemented per-model context. `health`: added `ModelCtx` and a `Models map[string]ModelCtx` field on `Status`, plus `PerSlotCtxFor(model)` (per-model figure when present, else host-level `PerSlotCtx` for a loaded model, else 0); moved `props` into a new `props.go` and added `propsModel`/`propsModels`. Poller rules 1-4: `/v1/models` treats an entry as loaded only with no `status` or `status.value=="loaded"` (other values dropped from `Loaded`); plain `/props` with `role:router` leaves host NCtx/Slots 0; each loaded model is asked `GET /props?model=<url.QueryEscape(id)>` and a failed/malformed answer leaves that id absent without failing the host; `Models` is a fresh non-nil map every successful poll, `MarkDown` leaves it. `ctxguard.go`: every `PerSlotCtx()` became `PerSlotCtxFor(model)` (leased host, candidates, wake "cannot serve" check) and `largestSlotCtx(hosts,h,model)` counts only hosts that have it loaded. `admin.go`: `HostView` gains `models` (empty object, never null). A plain single server keeps working as v2. All three given tests byte-identical; `make gate` → `gate: ok` on the first run. | ? |
 | v2.1/01-cancel-record | 2026-09-25 | done | 1 | pass | none | Implemented the rule: added a `cancelled` field to `forwardState`; the `ErrorHandler` sets it when it observes `context.Canceled` (client gone before any response byte) so the delivered row is no longer turned into a 499 by a pooled close after the body; removed the post-hoc `r.Context().Err()` check in the normal path, leaving the recover path's `http.ErrAbortHandler` (mid-body) check as the other 499 source. Given test failed the first run (`Errors:7`, status counts held 25×200/7×499), passes 3× under `-race`; `TestClientCancelMidStreamIsRecorded`, `TestClientCancelWhileQueuedIsRecorded` and `TestQueueFullIs503` still pass; `forward.go` 230 lines; `make gate` printed `gate: ok` on the first run. | ? |
 | v2/05-wiring-smoke | 2026-09-25 | done | 1 | pass | none | The wiring in `cmd/crossbar/main.go` and `internal/proxy/{proxy,forward,ctxguard}.go` plus the README section were already in the working tree from a prior session; this session only ran the tests, the gate, the log row, and the commit. `go test -race -count=1 ./...` failed once on `TestQueueFullIs503` (`Errors:2`, the 503 not recorded) — the known v1 recording defect the owner scheduled as a v2.1 task 01; reran once and it passed. `make gate` printed `gate: ok` on the first run. Committed the two owner-corrected given v1 tests (`internal/limiter/limiter_test.go`, `internal/proxy/proxy_test.go`) alongside the prior session's changes. | ? |
