v1 plan: leases, limiter, chooser, fingerprint, SQLite store, accounting, admin — acceptance tests first, no reference

Every given test compiled against a panic-only interface skeleton (go vet clean); nothing was
implemented. modernc.org/sqlite v1.59.0 vetted in a scratch module (WAL works); go.sum given.

+# v1 task 07: the smoke run and the README
+
+**Branch:** `v1` (run `git switch v1`; `git status --short` must be empty, otherwise stop)
+**Commit subject:** `Smoke run for v1; README for leases, admin and accounting`
+
+## Goal
+
+Prove v1 end to end with the given `tools/smoke.sh` — leases, header route, pin, queue, drain,
+failover and recovery, streaming with the usage chunk intact, usage and metrics — and bring the
+README up to date.
+
+## Files
+
+- Copy (**replaces** v0's): `tools/smoke.sh`, `cmd/fakeupstream/main.go`
+- Modify: `README.md`, `docs/implementer-log.md`
+
+## Steps
+
+- [ ] **1. Copy and run.**
+
+```sh
+git switch v1
+cp docs/plans/v1/_files/tools/smoke.sh tools/
+cp docs/plans/v1/_files/cmd/fakeupstream/main.go cmd/fakeupstream/
+make smoke
+```
+
+Expected last line: `smoke: ok (stream spread N ms)`, N ≥ 600. The script prints which numbered
+check failed and crossbar's log. A failure is a defect in tasks 01–06 **or in the script**: fix
+code only when a rule from an earlier task was broken; if the script's expectation contradicts a
+task rule, stop and report which.
+
+- [ ] **2. Update `README.md`.** Keep the seven v0 sections; change: the intro (leases, not "first
+  healthy host"); `## Configure` gets `db`, `lease_idle`, `retention`, `queue_max` in the table and
+  the new `example.toml`; `## Point clients at it` adds the `X-Crossbar-Route` header
+  alternative; `## Inspect` becomes `## Operate` and documents all six endpoints with one example
+  each (`GET hosts`, `GET routes`, `POST routes/{route}` pin and release, `POST hosts/{host}`
+  drain, `GET usage` JSON and text, `GET metrics`), taken from the smoke run; `## What v1 does not
+  do`: context-size guard, wake-on-LAN, Tailscale identity, `/slots` — see `PLAN.md` v2.
+- [ ] **3. Run the gate.** `make gate`. **4. Log and commit.** Row `v1/07-smoke-readme`, with the smoke line in Notes.
+
+```sh
+git add tools/smoke.sh cmd/fakeupstream/main.go README.md docs/implementer-log.md
+git commit
+```
+
+## Done when
+
+- `make smoke` prints `smoke: ok (…)`; `make gate` prints `gate: ok`; both copied files byte-identical.
+
+## Stop and report if
+
+- `make smoke` fails twice in the same way.
