The fast-path (PR->release/**) does not run the full unit+integration suites,
so four merged feature PRs shipped with stale/incorrect tests that only surface
on the release PR (PR->main). Repairs (features are correct; align tests to the
new behavior — no assertions weakened):
- #5480 (gate claude adaptive thinking): adaptive thinking is now injected only
for a real Claude Code client (x-app:cli / claude-code UA), not for any bare
Claude OAuth token. claude-thinking-tool-choice-guard + base-thinking-budget-5312
now identify as a Claude Code client to exercise the adaptive path (3 tests).
- #5527 (T02 inflation guard): the guard reverts a stacked body that did not
shrink in tokens. The bail-out/advancement fixtures used growth-appending mock
engines; they now carry a droppable padding message the engines empty, so the
body realistically shrinks and the marker assertions survive. bailout (5),
stacked-async (3), engine-enabled-toggle (2).
- #5427 (render onboarding wizard at /providers/new): integration-wiring asserted
the old redirect stub; now asserts the route renders ProviderOnboardingWizard.
- #5521 (mimocode SOCKS5 per-account proxy): the constructor's default account
omitted the proxy field (undefined), breaking the 'all proxies null' backward
compat guard. Default it to null, mirroring syncAccountsFromCredentials().
