GET /api/charts/workloads-summary has had no first-party caller since
the v6 import: ChartsAPI.getWorkloadsSummaryCharts arrived with it and
nothing ever called it. GET /api/charts/storage-summary lost its last
reader when storageSummaryTrendCache.ts was deleted on 2026-05-26.
Both still cost something. The workloads route carried a payload cache,
an SLO test in the release latency gate and a benchmark, and mock mode
rebuilt the 24-hour storage aggregate on every sampler tick for a cache
nothing read.
No stable release ever requested either route from the browser: v6.0.0
and later carry no caller, and the storage trend reader shipped only in
v6.0.0-rc.1 to rc.5. Neither route is in docs/API.md (a list of common
endpoints, not a complete one), and pulse-pro, pulse-mobile and
pulse-dev-infra never call them. A monitoring:read token could reach
them, so a private script may notice, but nothing known depends on
them. pulse-enterprise names the SLO test only as fixture data, and its
latency gate passes a test that is absent from the candidate as
removed. So the routes go with their clients:
handlers, response types, the monitor trend helpers, the mock aggregate
and its prewarm, the SLO budget, the benchmark, and the ChartsAPI
methods and types. Requests to either path now get 404.
buildMockWorkloadMetricHistorySeries goes too, because the
workloads-summary handler was its only production caller.
A TypeScript reference graph from src/index.tsx finds no production
reference to the removed methods or types. The production build loses
only the two static methods from the ChartsAPI chunk (326 B raw, 49 B
gzip); every other file differs only by chunk hashes and SRI values.
deadcode ./cmd/pulse and golangci unused report nothing newly
unreachable. On private mock stacks the Proxmox overview in Trends, a
guest History drawer and the storage page make the same chart requests
before and after at 1440 and 390 px, and neither build requested the
removed routes.
Contract prose that still described either route as live now records
the retirement, and the workload chart guard pins the per-type metric
sets the surviving /api/charts/workloads route requests.
Contract-Neutral: Storage history behavior is documented in the staged API and storage contracts and covered by staged focused regressions; shared router references do not change agent-lifecycle, performance, or security contracts, and the proof allowlists do not yet name the focused test files.
