/perf named a category. Dyno names the thing: a dyno tells you what an engine actually puts down, which is exactly what the page does. It straps the site to the rollers once a night and records a pull. And it belongs on the garage shelf with the other instruments.

The change

• /garage/dyno + /garage/dyno.json, worker-rendered. An exact ROUTES entry beats the /garage/<page> PREFIX, so no static file is involved.
• /perf and /perf.json 301 to them. The old names lived about an hour, so the redirects aren't for humans: agents: true publishes a surface into the MCP resources projection, and _headers caches the well-known cards for 30 days, so an agent can hold the old path long after a deploy could purge it.
• section: garage, kind: content, gallery + sitemap on. It now appears on the garage shelf, in the garage Run sub-palette (19 entries), and in the sitemap. The Explorer chrome nests it properly: aadhar.sh › Garage › Dyno, with "Up to Garage" in the task pane.
• No understanding check. Like /lens it's an instrument rather than an explainer, and check-page-contracts only walks HTML on disk.
• Copy leans on the metaphor where the metaphor is honest. "Recent pulls," and the note on why sampled figures are absent now closes: a dyno with a wandering needle is a decoration.

Two things this turned up, both bigger than the rename

run_worker_first has a hard ceiling of 100 rules, and we're at exactly 100

Adding two paths took it to 102 and wrangler refused to boot:

Error: Too many `run_worker_first` rules were provided;
102 rules provided exceeds max of 100.

Neither npm run build nor wrangler deploy --dry-run catches this. The route harness does, because it starts a real Worker. The two entries turned out to be redundant anyway (/garage/* already covers them), so this ships at 100 unchanged.

The next person to add a worker-first path has zero headroom. The list also carries 7 duplicate entries (/garage/*, /garage, /lens, /lens/, /photos, /photos/, /rn.md each appear twice) which wrangler dedupes away rather than spends — so deduping buys nothing, and real headroom needs consolidation onto wildcards. Flagging rather than fixing here; it deserves its own change.

The rename shipped a ReferenceError past a green test suite

renderPerf got renamed at its declaration but not at its one call site inside handleDyno:

ReferenceError: renderPerf is not defined
    at handleDyno (dyno.js:302:3)

All 200 contract tests passed, because they import and call renderDyno directly and never go through the handler. /garage/dyno.json returned 200 the whole time; only the HTML route 500'd. The route oracle caught it.

A test that exercises a function is not a test that exercises the wiring around it.

Verification

• npm run routes:check — 122 routes, 0 hard failures, including /garage/dyno 200, /garage/dyno.json 200, and both old paths 301
• npm test 200 pass · npm run build invariants ok · typecheck · pages:check · perf-budget green
• Rendered in a real Worker and checked in the browser: chart, breadcrumb, task pane, garage shelf card
