Bundle 2's OIDC- first-admin will plug in alongside as an alternate Strategy. * BootstrapService.ValidateAndMint: validates the operator's CERTCTL_BOOTSTRAP_TOKEN, mints a 32-byte (64-hex-char) random API key value, persists the SHA-256 hash to api_keys, grants r-admin via actor_roles, AddHashed's the runtime keystore so the just- minted key authenticates the next request without restart, and records bootstrap.consume to the audit trail with category=auth. * internal/auth/keystore.go (new): KeyStore interface + StaticKeyStore (immutable env-var-only path) + MutableKeyStore (env-var keys + DB-loaded api_keys + runtime AddHashed). The auth middleware now consumes a KeyStore so the bootstrap path can extend the lookup table at runtime. * migrations/000031_api_keys.up/down.sql: api_keys table with (id, name UNIQUE, key_hash UNIQUE, tenant_id, admin, created_by, created_at, expires_at, last_used_at). Idempotent. * /v1/auth/bootstrap GET (probe) + POST (mint) — auth-exempt. Both routes documented in api/openapi.yaml + AuthExemptRouterRoutes allowlist updated. The token never leaves internal/auth/bootstrap; the minted plaintext key flows only into the HTTP response body. * Startup warning emitted when CERTCTL_BOOTSTRAP_TOKEN is set AND admin actors already exist (config drift signal). * Tests: 4 strategy invariants (empty token born disabled, wrong token=ErrInvalidToken without consumption, one-shot consumption, admin-exists closes path), 5 service tests (happy path + actor- name validation + propagation of strategy errors + nil-deps guard + 32-byte entropy budget), 8 HTTP-handler tests (status 201/410/401/400 mapping + token-leak hygiene scan of slog + audit details + Location header). Token-leak test redirects slog.Default to a buffer for the test scope. # Phase 7 — API-key migration + scope-down CLI * GET /v1/auth/keys handler + service method ListKeys backed by ActorRoleRepository.ListDistinctActors. Returns one row per (actor_id, actor_type) pair with the slice of role IDs they hold. Permission: auth.role.list. * internal/cli/auth_scope_down.go: AuthListKeys, AuthScopeDown (interactive), AuthScopeDownNonInteractive (JSON config), AuthScopeDownSuggest (--suggest with optional --apply). The synthetic actor-demo-anon is filtered out of every interactive / bulk path; non-interactive flow logs and skips it explicitly. * SuggestRoleFromAuditEvents (pure function): walks 30 days of audit events per actor and returns the narrowest matching role (admin / mcp / viewer / agent / operator) plus a one-line reason. Classification: any admin-shaped action wins; otherwise all-MCP → mcp; all-read-only → viewer; all-agent-shaped → agent; otherwise operator. Test table pins all six classifications. * CLI subcommand tree extended: 'auth keys list' + 'auth keys scope-down [--non-interactive <cfg>] [--suggest [--apply]]'. * CHANGELOG.md leads v2.1.0 with the SECURITY: AUDIT YOUR API KEYS call-out + four flow examples. # Phase 8 — auditor role + event_category column * migrations/000032_audit_category.up/down.sql: ALTER TABLE audit_events ADD COLUMN event_category TEXT NOT NULL DEFAULT 'cert_lifecycle' + CHECK constraint (cert_lifecycle/auth/config) + (event_category) and (event_category, timestamp DESC) indexes for the auditor-filter query path. WORM trigger from migration 000018 continues to enforce append-only at the DB layer (DDL is not blocked). * domain.AuditEvent gains EventCategory string (omitempty); domain.EventCategoryCertLifecycle / Auth / Config constants. * AuditService.RecordEventWithCategory sibling of RecordEvent; legacy callers stay on RecordEvent (defaults to cert_lifecycle). Auth callers (RoleService, ActorRoleService, BootstrapService) switched to RecordEventWithCategory(..., 'auth', ...). * GET /v1/audit?category=<cat>: handler accepts the optional query param, validates against the enum (400 on invalid value), dispatches through ListAuditEventsByCategory. OpenAPI updated with the new query param + AuditEvent.event_category schema. * Postgres AuditRepository.Create now writes event_category; AuditRepository.List filters on it; AuditFilter.EventCategory gates the WHERE clause. * Tests: 5 audit-category-filter HTTP tests (dispatch routing, back-compat fallback, 400 for invalid values, all 3 enum values accepted, page+category combine, JSON output surfaces the field). 3 auditor-role invariants (auditor holds exactly audit.read+audit.export, no mutating perms, disjoint from viewer except audit.read). # Cross-phase wiring * HandlerRegistry.Bootstrap field added; cmd/server/main.go wires the bootstrap service ahead of RegisterHandlers (extracted assembleNamedAPIKeys helper into auth_backfill.go, moved the keystore + bootstrap construction up alongside the auth repos). * AuthCheckResolver / AuthActorRoleService extended with ListKeys to satisfy the Phase 7 surface; existing fakes updated. * fakeAudit + mockAuditService stubs in tests gain RecordEventWithCategory + ListAuditEventsByCategory; existing tests untouched. # Verifications * gofmt -l: clean across every modified file. * go vet ./...: clean. * staticcheck across internal/auth + handler + router + cli + service + repository + cmd + domain: clean. * go test -short -count=1: green across every Bundle-1-touched package — internal/auth (incl. bootstrap), internal/api/handler, internal/api/router, internal/cli, internal/service/auth, internal/service, internal/domain/auth, internal/repository/postgres, cmd/server, cmd/cli, plus internal/scheduler, internal/api/middleware, cmd/agent, internal/mcp.	2026-05-09 20:15:43 +00:00
shankar0123	60a589ab96	auth-bundle-1 Phase 0-5 closure: demo-mode wire, named-key backfill, AuthCheck enrichment, OpenAPI schema, intermediate-ca comment refresh ... Closes the 5 gaps the post-Phase-5 audit flagged on dev/auth-bundle-1. C1: cmd/server/main.go now selects auth.NewDemoModeAuth() when CERTCTL_AUTH_TYPE=none and falls back to auth.NewAuthWithNamedKeys otherwise. Pre-closure, the no-op pass-through that NewAuthWithNamedKeys returns for empty keys would have left ActorIDKey / ActorTypeKey / TenantIDKey unpopulated and 401'd every Phase-3.5 rbacGate-wrapped admin route + every Phase-4 RBAC handler in demo deployments. NewDemoModeAuth injects the synthetic 'actor-demo-anon' actor seeded by migration 000029, which holds r-admin at global scope. C2: backfillNamedKeyActorRoles startup hook (cmd/server/auth_backfill.go) iterates CERTCTL_API_KEYS_NAMED entries (and legacy CERTCTL_AUTH_SECRET synthesized fallbacks) and grants r-admin or r-viewer to each via authActorRoleRepo.Grant before the HTTP server starts accepting requests. Idempotent via ON CONFLICT DO NOTHING in the repo. Failures log a warning but are non-fatal — the server still starts and the operator can fix grants via /v1/auth/keys. Helper extracted from main.go so the role-mapping invariant is pinned by 4 focused unit tests (admin->r-admin, non-admin->r-viewer, empty no-op, grant-error non-fatal, nil-logger safe). M1: HealthHandler.AuthCheck now returns actor_id, actor_type, tenant_id, roles, effective_permissions, and admin_via_role when the optional AuthCheckResolver is wired (production path: authCheckResolverAdapter wraps the postgres ActorRoleRepository in main.go). Nil resolver preserves the legacy {status, user, admin} contract for back-compat with pre-Bundle-1 GUIs and test fixtures. Adds 2 regression tests + 1 fake resolver shim. M2: refreshes the stale 'Admin gate: every method calls auth.IsAdmin first' comment on IntermediateCAHandler — the gate moved to router.go::rbacGate via auth.RequirePermission middleware in Phase 3.5; the new comment block points readers there. M4: 11 RBAC routes (auth/me, auth/permissions, 5 role lifecycle, 2 role-permission grant/revoke, 2 actor-role grant/revoke) added to api/openapi.yaml under the [Auth] tag with operationIds and shared AuthRole / AuthRolePermission schemas. AuthCheck path extended with the Bundle-1 enrichment fields. The 11 entries removed from openapi_parity_test.go::SpecParityExceptions. Tests: go vet + staticcheck + go test -short -count=1 green across cmd/server/, internal/auth/, internal/api/router/, and internal/api/handler/. New tests: 4 backfill unit tests, 2 AuthCheck M1 enrichment tests, 1 demo-mode + rbacGate chain integration test (TestRBACGate_DemoModeChainReachesHandler). Branch SECURITY.md (cowork/auth-bundle-1-SECURITY.md, not part of this commit) captures the full posture of dev/auth-bundle-1 as of this closure for the operator's pre-merge review.	2026-05-09 19:33:07 +00:00
