Implements the ratified #295 design (PR1, server-only, backward compatible). The
/api surface now accepts a valid X-Api-Key (machine) OR an authenticated session
(browser cookie, local login or OIDC), gated by the evolved ApiAuthorizationFilter
(renamed from ApiKeyAuthorizationFilter; same fail-closed EndpointRequiresKey
predicate). Machine/key behavior is byte-identical and the SPA keeps working via
its stored key — the SPA login flow lands in PR2.
- ApiAuthorizationFilter: key-first (CSRF-immune) then session; session-authed
mutations require the X-CSRF header (403 otherwise). Attributes renamed
[RequiresApiKey]->[RequiresAuthentication], [SkipApiKeyAuthorization]->[SkipApiAuthorization].
- Cookie scheme ctv-session always registered (Lax/SameAsRequest/14d sliding, 401 not
redirect for /api); OIDC handler revived when configured (profile scope, userinfo,
auth-method claim); UseAuthentication/UseAuthorization/UseRateLimiter revived in the
legacy MapWhen branch.
- Local admin = single credential in ConfigElement rows (username / PBKDF2 hash via
Microsoft.Extensions.Identity.Core / rotating security stamp) — NO DB migration.
Password change rotates the stamp; CookieSecurityStampValidator revokes stale local
sessions. Env-seed recovery (Auth:LocalAdmin:*) via LocalAdminSeedService.
- AuthController /api/auth/{config,session,setup,login,logout,password} + browser-nav
GET /auth/oidc/login; excluded from OpenAPI (machine-audience spec). Per-IP rate limit
on login/setup/password; dummy-hash verify (no user enumeration).
- ForwardedHeaders now strict opt-in: X-Forwarded-* ignored unless KnownProxies/Networks
configured (rate-limiter IP + cookie-Secure integrity). Deployment: operators behind a
proxy must set ForwardedHeaders:KnownProxies.
- Tests: session/CSRF filter cases + 17 Application/Auth handler tests; full ErsatzTV.Tests
green (1499). No OpenAPI/generated-artifact drift.
- Docs: api-conventions section 9 rewritten; decisions.md entry (supersedes #206 inert-OIDC note).

Adversarial-review follow-ups:
- OpenApiSerializerContractTests: add a fifth case, a fully-populated
ChannelResponseModel — the only DTO with a [JsonProperty("ffmpegProfile")]
override, i.e. the attribute path of NewtonsoftSchemaNamingTransformer that
the existing four cases never exercised.
- NewtonsoftSchemaNamingTransformer: a rename colliding with an existing schema
key now throws InvalidOperationException (naming the type and keys) instead of
silently overwriting/dropping a property — the generator must never emit a
lossy spec.

The OpenAPI document is generated from System.Text.Json metadata, whose
camelCase drifted from the runtime MVC serializer (Newtonsoft via
CustomContractResolver/CustomNamingStrategy): the spec said "fFmpegProfileId"
and "fFmpegProfile" while the wire emits "ffmpegProfileId" (naming-strategy
special case) and "ffmpegProfile" (ChannelResponseModel's [JsonProperty]
override). That fed the SPA the wrong keys.
Add NewtonsoftSchemaNamingTransformer, an OpenAPI schema transformer registered
on all three documents that renames each object schema's Properties (and
Required) keys through the SAME Newtonsoft contract resolver the runtime uses,
so the spec matches the wire format by construction. Regenerate v1.json.
Guard with OpenApiSerializerContractTests: serializes fully-populated DTOs
through the runtime Newtonsoft settings and pins the v1.json schema property
sets to the emitted keys, failing if generation drifts again.
