zeekay 551236b1a5 route: one namespace — everything chat serves lives under /v1/chat
Five things answered outside /v1/chat/. Four of them are chat's; they move.

  /health                -> /v1/chat/health
  POST /oauth/iam/session-> POST /v1/chat/auth/iam/session   (it is auth)
  GET  /oauth/openid[/callback], /oauth/error
                         -> /v1/chat/auth/openid[/callback], /v1/chat/auth/error
  /images/               -> /v1/chat/images/

The fifth — the built assets at / and the SPA catch-all — is the SPA's, and
stays. Every caller moved in the same commit: api-endpoints (health, iamSession),
the metrics + telemetry health filter, the helm probes, the PR-preview workflow,
the PWA nav-fallback denylist. `ErrorController` matched a failed OIDC callback
by the substring '/oauth/', which the move would have silently broken; it now
matches the route.

Images are the one persisted case: a conversation stores the served path, and
history is immutable. New writes emit /v1/chat/images/…; /images/* answers one
permanent redirect; `isServedImage` (data-provider, the one place that knows the
namespace) recognises both. Local deletion maps the served path back to disk.

Two routers were written, tested, advertised to the browser — and never mounted,
so both were a guaranteed 404: skills (types say /v1/chat/skills) and the RUM
OTLP proxy (`rum/proxy` advertises /v1/chat/rum). Mounted where they said.

Deleted, with zero callers: server/experimental.js — a drifted second copy of
the whole mount table, still referencing a router that no longer exists, that
would have silently absorbed this move and diverged again; and nginx.hanzo.conf,
referenced by no compose/Dockerfile/chart, whose own /health shadowed chat's.

Gates collapsed to their one behavior, and the env deleted:

  ALLOW_SOCIAL_LOGIN     IAM is the one identity provider; false produced a
                         server with no way to sign in. socialLogins.js is now
                         iamLogin.js — one name for one thing.
  CONTINUE_ON_UNCAUGHT_EXCEPTION  keeps a process alive in an unknown state
                         instead of letting the kubelet replace it.
  CONFIG_BYPASS_VALIDATION        boots on invalid config, on request.
  MCP_SKIP_CODE_CHALLENGE_CHECK   turns off PKCE verification.
  OPENID_JWKS_URL_CACHE_ENABLED   read as `isEnabled(x) || true` — never off.
                         A second, differently-defaulted read lived in
                         remoteAgentAuth; both are now just on.
  NO_INDEX               a third boolean idiom for a header we always want.
  DISABLE_COMPRESSION, ENABLE_IMAGE_OUTPUT_GZIP_SCAN — we write these images
                         ourselves, as PNG/GIF; none is gzipped on disk.

Tests fail without the change: the auth router spec (6 of 7) against the old
router, the static spec against the old env-gated one, the config spec now sets
CONFIG_BYPASS_VALIDATION=true and still expects the exit, the error spec against
the '/oauth/' matcher, and index.spec asserts the top level serves HTML — so a
probe or caller left behind fails loudly instead of looking green.
