Refresh() POSTed a JSON body with Content-Type: application/json to
/api/auth/oauth/token, but that endpoint is the @node-oauth/oauth2-server token
handler, which REQUIRES application/x-www-form-urlencoded and rejects JSON with
"content must be application/x-www-form-urlencoded". The custom device-flow
endpoints (/device, /device-token) accept JSON, so LOGIN worked — but every
refresh failed, so OAuth auth silently died after the 1h access-token TTL
(observed live: whoami → "device login failed: ... must be
application/x-www-form-urlencoded").

Fix: add postForm() (x-www-form-urlencoded) and send the refresh grant through
it. Verified live: an expired session refreshes cleanly against prod.

The bug slipped #4's tests because TestRefreshRotatesToken's mock decoded the
request body as JSON (accepting the wrong content-type). Hardened it to assert
Content-Type: application/x-www-form-urlencoded + ParseForm — it now FAILS on a
JSON refresh and PASSES on the form-encoded one.

…im that was measured wrong (#204)

The canonical handoff doc on `main` had gone stale in the way that costs the
next session real time: it still listed shipped work as pending, and carried one
confident claim that measurement disproved.

🔴 THE DEDUP ADVICE WAS WRONG AND WOULD HAVE SHIPPED A BROKEN METRIC. The doc
said \"per-mount, so unique views need query-side dedup\". `blockInstanceId` is
NOT per-mount — it is `page_apb_<ULID>`, roughly one per PLACEMENT. Measured on
prod: 124 rows carried 28 distinct `blockInstanceId` across 27 distinct
`appBlockId`, ~1:1 with the app, so deduping on it reports ~1 unique viewer per
app. Corrected in place, with the measurement, because the wrong version was
specific and plausible enough to be followed.

Brought current:

- Follow-ups #6 and #5 marked DONE (civitai#3613 + cli#195, civitai#3626), plus
  cli#193/#194 and civitai#3627. The DONE table goes 8 -> 15 PRs.
- `preview / component-tests` is no longer an open question: it reported success
  on #3606 and every subsequent PR (1259/1259), verified by reading the locator
  at each PR's head SHA rather than inferring from timing.
- Deploy/verify status now records that the feature was verified IN PRODUCTION,
  not merely deployed — with the caveat that 20ms against ~125 rows in one
  partition proves the query is correct today, not that partition pruning holds
  at scale.
- Records how to actually READ the preview component log (it lives in the Tekton
  taskrun, not behind the GitHub status URL), and that the taskrun reports
  Succeeded even when the suite fails because the step is report-only.
- The pins rot recurred within a day exactly as predicted — cli#203 re-bumped
  both pins on 2026-08-05 — so that is now documented as a standing property of
  the repo, not an incident to diagnose a third time.
- Adds the marketplace search-debounce flake (338ms measured against its own
  300ms budget) as a latent issue for whoever owns that test.

A security finding from this stream was reported privately per SECURITY.md. The
mechanism is deliberately NOT in this doc — only the operational consequence,
and a pointer to ask security before changing the ingest path.

Docs-only; `make ci` green and `gofmt -s -l .` prints nothing.
