Phase 32 foundation. The SaaS control plane (private molecule-controlplane
repo) provisions one platform instance per customer org on Fly Machines
and sets MOLECULE_ORG_ID=<uuid> on the machine. Its subdomain router
forwards requests with X-Molecule-Org-Id=<uuid>.
TenantGuard:
- When MOLECULE_ORG_ID is set → every non-allowlisted request must carry a
matching X-Molecule-Org-Id header. Mismatched/missing header → 404 (not
403 — don't leak tenant existence by letting probers distinguish "wrong
org" from "route doesn't exist").
- When unset → passthrough. Self-hosted / dev / CI behavior unchanged.
- Allowlist is exact-match, not prefix — /health and /metrics only.
No orgs table, no signup, no billing, no Fly provisioning in this repo —
all that lives in the private control plane. The public repo's SaaS
surface is exactly this one middleware.
6 tests covering: unset-is-passthrough, matching header, mismatched
header 404 (with empty body), missing header 404, allowlist bypass, and
allowlist-is-exact-match.

Three unauthenticated routes allowed arbitrary read/write/delete of all
global platform secrets (API keys, provider credentials) with zero auth:
- GET/PUT/POST /settings/secrets
- DELETE /settings/secrets/:key
- GET/POST/DELETE /admin/secrets (legacy aliases)
Fix: new AdminAuth middleware with same lazy-bootstrap contract as
WorkspaceAuth — fail-open when no tokens exist (fresh install / pre-Phase-30
upgrade), enforce once any workspace has a live token. Any valid workspace
bearer token grants access (platform-wide scope, no workspace binding needed).
Changes:
wsauth/tokens.go — HasAnyLiveTokenGlobal + ValidateAnyToken functions
wsauth/tokens_test.go — 5 new tests covering both new functions
middleware/wsauth_middleware.go — AdminAuth middleware
router/router.go — global secrets routes now registered under adminAuth group

Fix A — platform/internal/middleware/wsauth_middleware.go (NEW):
WorkspaceAuth() gin middleware enforces per-workspace bearer-token auth on
ALL /workspaces/:id/* sub-routes. Same lazy-bootstrap contract as
secrets.Values: workspaces with no live token are grandfathered through.
Blocks C2, C3, C4, C5, C7, C8, C9, C12, C13 simultaneously.
Fix A — platform/internal/router/router.go:
Reorganised route registration: bare CRUD (/workspaces, /workspaces/:id)
and /a2a remain on root router; all other /workspaces/:id/* sub-routes
moved into wsAuth = r.Group("/workspaces/:id", middleware.WorkspaceAuth(db.DB)).
CORS AllowHeaders updated to include Authorization so browser/agent callers
can send the bearer token cross-origin.
Fix B — workspace-template/heartbeat.py:
_check_delegations(): validate source_id == self.workspace_id before
accepting a delegation result. Attacker-crafted records with a foreign
source_id are silently skipped with a WARNING log (injection attempt).
trigger_msg no longer embeds raw response_preview text; references
delegation_id + status only — removes the prompt-injection vector.
Fix C — workspace-template/skill_loader/loader.py:
load_skill_tools(): before exec_module(), verify script is within
scripts_dir (path traversal guard) and temporarily scrub sensitive env
vars (CLAUDE_CODE_OAUTH_TOKEN, ANTHROPIC_API_KEY, OPENAI_API_KEY,
WORKSPACE_AUTH_TOKEN, GITHUB_TOKEN, GH_TOKEN) from os.environ; restore
in finally block. Defence-in-depth even if /plugins auth gate is bypassed.
Fix D — platform/internal/handlers/socket.go:
HandleConnect(): agent connections (X-Workspace-ID present) validated via
wsauth.HasAnyLiveToken + wsauth.ValidateToken before WebSocket upgrade.
Canvas clients (no X-Workspace-ID) remain unauthenticated.
Fix D — workspace-template/events.py:
PlatformEventSubscriber._connect(): include platform_auth bearer token in
WebSocket upgrade headers alongside X-Workspace-ID.
Fix E — workspace-template/executor_helpers.py:
recall_memories() and commit_memory() now pass platform_auth bearer token
in Authorization header so WorkspaceAuth middleware allows access.
Fix F — workspace-template/a2a_client.py:
send_a2a_message(): timeout=None → httpx.Timeout(connect=30, read=300,
write=30, pool=30). Resolves H2 flagged across 5 consecutive audits.
Tests: 149/149 Python tests pass (test_heartbeat + test_events updated to
assert new source_id validation behaviour and allow Authorization header).
