Build and browser-verify the tenant-picker frontend page
web/src/routes/select-tenant now calls enterprise-auth's existing
GET /auth/memberships / POST /auth/select-tenant protocol (built earlier
this phase, previously called only from Go tests) via
fetch(..., {credentials: 'include'}) -- new listMemberships/selectTenant
functions in $lib/api.ts, using a dedicated request helper that reads
plain-text error bodies (loginhandler's http.Error responses), unlike
every other request helper in that file which expects JSON.
Credentialed cross-origin fetch needed CORS enterprise-auth didn't have:
api/httpserver.WithCORS's wildcard-friendly default can't be combined
with a credentialed request at all (browsers refuse to honor
Access-Control-Allow-Origin: "*" on one) -- added WithCredentialedCORS
(literal origin, Access-Control-Allow-Credentials: true) alongside it,
wired into enterprise-auth via a new CORS_ALLOWED_ORIGIN config var
defaulting to POST_LOGIN_REDIRECT_URL (web's own origin, the same
default pattern SELECT_TENANT_REDIRECT_URL already used).
adapter-static's route crawler doesn't discover a page nothing links to
(this one is only ever reached via enterprise-auth's redirect) -- fixed
with select-tenant/+page.ts's `export const prerender = true`, the same
declaration every other route already has.
Genuinely verified in a real browser in this environment, not just
type-checked: a throwaway Node server standing in for enterprise-auth's
exact wire contract (including its plain-text error bodies), driven
through the full flow via mcp__claude-in-chrome -- cross-origin
pending-login cookie set, credentialed preflight + GET/POST round trip,
a real click choosing a tenant, the post-selection redirect, and the
missing/expired-cookie error path rendering the backend's actual
message. No Docker or live Postgres/IdP needed, since the point was
exercising web's own fetch/CORS/cookie wiring, not enterprise-auth's
internals (already covered by loginhandler's own tests).
This closes the tenant-picker as the last named gap in Phase 4. What's
left is the already-disclosed live-verification caveat shared by every
Postgres/ClickHouse-backed piece and both SSO protocols: none of this
has run against a real database, external IdP, or multi-container
deployment in this environment.

Build the tenant-picker backend protocol (no frontend yet, by design)
A multi-membership identity (belongs to more than one tenant) used to
get a flat 501 refusal -- named as undesigned future work across
CLAUDE.md/threat-model.md/the runbook since early Phase 4. Scope for
this change was agreed via AskUserQuestion: backend protocol only,
fully verified via real HTTP round trips, not the actual picker page --
web has zero session/cookie-handling code today (confirmed while
researching this), so building that is separately-scoped, unverifiable
frontend work in this environment (no live backend, no browser).
session.Manager gains IssuePendingLogin/ValidatePendingLogin, a second
JWT token type proving identity without committing to a tenant yet
(10-minute TTL). PendingLoginClaims is deliberately a distinct Go type
from Claims, and -- caught by this change's own test suite before it
shipped -- needed a JSON field name disjoint from Claims.UserID's
"user_id" too: go-jose's unmarshal is happy to populate a struct from
any token whose claims happen to share a key, so a real session token
would otherwise have parsed successfully as a pending login. Fixed via
"pending_user_id" instead; both directions (session-as-pending,
pending-as-session) now have regression tests.
rbacstore.ListMembershipsWithTenantForUser joins tenant_memberships
with tenants, since a picker needs display names, not just IDs.
loginhandler.resolveIdentity's multiple-membership branch no longer
errors -- finishLogin routes it into startTenantSelection instead,
which issues a pending-login cookie (Path=/auth, so it's never sent on
ordinary requests) and redirects to a new configurable
SelectTenantRedirectURL (defaults to {POST_LOGIN_REDIRECT_URL}/select-
tenant). Two new routes complete the round trip: GET /auth/memberships
lists the pending identity's real tenant options, and POST
/auth/select-tenant re-derives the role for the chosen tenant
server-side (never trusts a client-supplied role, refuses a tenant_id
outside the identity's actual memberships with 403) before issuing the
real session -- responding with JSON {"redirect_url": ...}, not a
redirect, since a POST/fetch caller should control its own navigation.
Verified with the same real-fake-IdP tests the rest of this package
uses (coreos/go-oidc's oidctest, crewjam/saml's samlidp): the full
login -> pending cookie -> GET /auth/memberships -> POST
/auth/select-tenant -> real session round trip for both protocols, plus
negative paths (missing/expired pending cookie, a tenant_id outside
membership, a real session token rejected as a pending login and vice
versa). ErrMultipleMemberships is removed -- it's not an error path
anymore.
Docs updated in lockstep: CLAUDE.md, threat-model.md (including its
summary table), phase-4-runbook.md (new §12), enterprise/README.md
(new "Tenant selection" section, explicit about what's still not built
and why: no session handling in web, no CORS on enterprise-auth).

Build SAML login (enterprise/internal/loginhandler), mirroring OIDC
Adds GET /auth/saml/login + POST /auth/saml/acs alongside the existing OIDC pair, both converging on the same upsert-user/resolve-tenant/ issue-session path. loginhandler.New now takes an optional *saml.ServiceProvider, RegisterRoutes registers each protocol's routes independently so either, both, or neither can be configured. SAML's replay/unsolicited-response defense (InResponseTo, standing in for OIDC's state) is carried via a SameSite=None sentry_saml_request cookie -- None because the ACS endpoint receives a cross-site POST from the IdP's origin, which SameSite=Lax cookies are never sent on. enterprise-auth's main.go now fetches+parses SAML_IDP_METADATA_URL at startup (samlsp.FetchMetadata) and wires the result through. Verified to the same bar as OIDC: a real fake IdP (crewjam/saml/samlidp, genuine XML signing/verification) drives the full login->ACS->session-cookie round trip and negative paths (bad InResponseTo, missing request cookie, missing email/NameID, no/multiple tenant memberships), all in loginhandler/saml_test.go, no Docker needed. The login-form HTML is bypassed by pre-seeding a saml.Session directly into samlidp's session store and presenting the matching `session` cookie -- an IdP-supported shortcut (confirmed by reading GetSession), the same "skip the UI, keep the crypto real" approach oidctest gave the OIDC tests. Writing that test caught two real bugs in internal/saml.ParseResponse, both fixed here: it never called r.ParseForm() before reading the POSTed SAMLResponse field, so every real ACS POST would have silently decoded an empty response; and its email-attribute matching missed urn:oid:0.9.2342.19200300.100.1.3 (the standard LDAP "mail" OID), which is what an IdP sends by default absent an explicit AttributeConsumingService request for "email" -- exactly what samlidp's own DefaultAssertionMaker does, and plausibly what real IdPs' default SAML app templates do too. Docs (CLAUDE.md, threat-model.md, architecture.md, enterprise/README.md, phase-4-runbook.md, docker-compose.yml's enterprise-auth comment) updated in lockstep: SAML login moves from "protocol mechanics only" to "built, verified with a real fake IdP, not yet tried against a real external IdP or a running enterprise-auth container" -- the same disclosed gap OIDC already carried. |

Phase 4: real OIDC human login (enterprise/internal/loginhandler)
Closes the other major named gap from this phase: until now, there was no way for a human to actually log in -- only /alerting's RoleService credential could be minted. GET /auth/oidc/login and GET /auth/oidc/callback drive the real coreos/go-oidc flow already wired in enterprise/internal/oidc: CSRF state in a short-lived cookie, code exchange, ID token verification, upserting a users row, resolving tenant/role from exactly one tenant_memberships row (refusing outright on zero or more than one, rather than guessing), and issuing a real session cookie. Unlike everything else built this phase, this one is genuinely verified end to end: the tests spin up coreos/go-oidc's own oidctest fake IdP, which signs real RS256 ID tokens, and drive the full login->callback-> session-cookie round trip through actual signature verification -- no live database or Docker needed, so nothing here is asserted without having actually been run in this session. Also fixes a real bug caught while wiring this into enterprise-auth's main.go: assigning a nil *oidc.Provider to the handler's interface field would have produced a non-nil interface wrapping a nil pointer (Go's classic typed-nil trap), silently breaking the "OIDC not configured" no-op path -- New() now takes the concrete pointer type and checks it before ever converting to the interface, with a regression test pinning the fix down. Still missing: SAML's equivalent (ACS endpoint), a tenant-picker UI for multi-membership identities, and any admin UI to actually create a tenant_memberships row (today that's manual SQL, documented in the runbook's new bootstrap walkthrough). |
