1. f675500: aria-hidden="true" on decorative SVG icons in
DeleteCascadeConfirmDialog warning icon and Toolbar stop/restart
/search/help icons. All have adjacent aria-label text or parent
button aria-label — correct.
2. eb87737: session cookie auth fallback for /registry/:id/peers
SaaS canvas path. verifiedCPSession() checked after bearer token
in validateDiscoveryCaller, allowing canvas to hit the Peers tab
via session cookie rather than bearer token. Self-hosted bypass
logic preserved.
3. 80fedd6: MissingKeysModal dialog semantics — role="dialog",
aria-modal="true", aria-labelledby="missing-keys-title",
requestAnimationFrame focus management. Also removes stale
aria-describedby={undefined} from CreateWorkspaceDialog.

PR #1229 sed command had no capture groups but used $1 in the
replacement, committing the literal string "defer func() { _ = \$1 }()"
instead of "defer func() { _ = resp.Body.Close() }()". Go does not
compile — $1 is not a valid identifier.
Fixed with: sed -i 's/defer func() { _ = \$1 }()/defer func() { _ = resp.Body.Close() }()/g'

Issue #1196: golangci-lint errcheck flags bare resp.Body.Close()
calls because Body.Close() can return a non-nil error (e.g. when the
server sent fewer bytes than Content-Length). All occurrences fixed:
defer resp.Body.Close() → defer func() { _ = resp.Body.Close() }()
resp.Body.Close() → _ = resp.Body.Close()
12 files affected across all Go packages — channels, handlers,
middleware, provisioner, artifacts, and cmd. The body is already fully
consumed at each call site, so the error is always safe to discard.

Addresses three Critical findings from today's code review of the
SaaS-canvas routing stack.
## Critical-1: session verification scoped to the current tenant
session_auth.go previously verified via GET /cp/auth/me, which
only answers "is someone logged in" — NOT "is this user in the
org they're targeting." Every WorkOS-authed user (including folks
who only signed up via app.moleculesai.app with no tenant
relationship) could call /workspaces, /approvals/pending,
/bundles/import, /org/import etc. on ANY tenant they could reach.
Cross-tenant read: user at acme.moleculesai.app could hit
bob.moleculesai.app/workspaces with their cookie and get Bob's
workspaces.
Fix:
- CP gains GET /cp/auth/tenant-member?slug=<slug> which joins
org_members × organizations and only returns member:true when
the authenticated user is actually in that org.
- Tenant sets MOLECULE_ORG_SLUG at boot via user-data.
- session_auth now calls tenant-member (not /me), passing its
own slug. Cache key includes slug so one tenant's cached
positive never satisfies another's check.
## Critical-2: cp_proxy path allowlist (lateral-movement fix)
cp_proxy.go forwarded any /cp/* path upstream with the cookie
and bearer attached. Since /cp/admin/* accepts sessions as one
of its auth tiers, a tenant-authed user could curl
/cp/admin/tenants/other-slug/diagnostics through their tenant
and the CP would honor it — turning any tenant into a lateral
hop into admin surface.
Fix: explicit allowlist of paths the canvas browser bundle
actually needs (/cp/auth, /cp/orgs, /cp/billing, /cp/templates,
/cp/legal). Everything else 404s at the tenant before cookies
leave. Fail-closed: future UI paths require explicit entries.
## Important-1,2: bounded session cache + split positive/negative TTL
Previous sync.Map cache grew unbounded (one entry per unique
Cookie header for process lifetime) and cached failures for 30s,
meaning a 3s CP blip locked users out for the full window.
Fix:
- Bounded map with batch random eviction at cap (10k entries ×
~100 bytes = 1 MB ceiling). Random eviction is O(1)
expected; we don't need precise LRU.
- Periodic sweeper goroutine (2 min) reclaims expired entries
even when they're not re-hit.
- Positive TTL 30s, negative TTL 5s — short negative so CP
flakes self-heal fast.
- Transport errors NOT cached (would otherwise trap every
user during a multi-second upstream outage).
- Cache key = sha256(slug + cookie) so raw session tokens
don't sit in process memory, and cross-tenant isolation is
structural not policy.
## Important-3: TenantGuard /cp/* bypass documented
Added a security note to the bypass explaining why it's safe
only under the current setup (cp_proxy allowlist + tunnel-only
ingress), and what would require revisiting (SG opens :8080
inbound to the VPC).
## Tests
- session_auth_test.go: 12 new tests — empty cookie, missing
slug, no CP, member:true happy path with cache hit, member:
false, 401 upstream, malformed JSON, transport error not
cached, cross-tenant isolation (same cookie different
tenants hit upstream separately), bounded eviction, expired
entries, cache key collision resistance.
- cp_proxy_test.go: new — isCPProxyAllowedPath covers 17
allow/block cases, forwarding preserves Cookie+Auth, Host
rewritten, blocked paths 404 without calling upstream.
All platform tests pass. CP provisioner tests pass after
threading cfg.OrgSlug into the container env.

Canvas (SaaS tenant UI) runs in the browser and authenticates the
user via a WorkOS session cookie scoped to .moleculesai.app. It
has no bearer token — the token-based ADMIN_TOKEN scheme is for
CLI + server-to-server callers, not end users.
Adds a session-verification tier to AdminAuth that runs BEFORE the
bearer check:
1. If Cookie header present AND CP_UPSTREAM_URL configured →
GET /cp/auth/me upstream with the same cookie. 200 + valid
user_id → grant admin access. Non-200 → fall through.
2. Else (no cookie, or no CP configured, or CP said no) →
existing bearer-only path unchanged.
Positive verifications are cached 30s keyed by the raw Cookie
header, so a burst of canvas admin-page renders doesn't DDoS
the CP. Revocations propagate within that window.
Self-hosted / dev deploys without CP_UPSTREAM_URL: feature
disabled, behavior unchanged. So this is strictly additive for
the SaaS case.
