Repro

A fresh staging tenant (canary 004947743811, image platform-tenant:latest = a93c4ce) was provisioned 2026-05-10 ~01:48 UTC. Probes:

GET /buildinfo → 200 {"git_sha":"a93c4ce17725493390e39b0cf9a78fdada2561d4"}
GET /metrics → 200 prometheus
POST /org/import (Bearer ADMIN_TOKEN) → 404 content_length=0
POST /workspaces (Bearer ADMIN_TOKEN) → 404 content_length=0
POST /agents → 404 content_length=7639  (HTML — proxied to canvas)

content_length=0 is gin's default 404 body (route not registered). content_length=7639 is canvas's HTML 404 (route was proxy-fallback'd).

So the Go binary's router has /buildinfo + /metrics but NOT /org/import, /workspaces. Yet git show a93c4ce17725493390e39b0cf9a78fdada2561d4:workspace-server/internal/router/router.go shows:

r.POST("/org/import", middleware.AdminAuth(db.DB), orgh.Import)
wsAdmin.POST("/workspaces", wh.Create)

Hypothesis

The build pipeline (Dockerfile.tenant → go build ./cmd/server) is compiling from a different source tree than the labeled GIT_SHA, OR a missing replace target is silently dropping handler files.

The Dockerfile has:

RUN echo 'replace github.com/Molecule-AI/molecule-ai-plugin-github-app-auth => /plugin' >> go.mod

If the github-app-auth plugin import affects router setup (e.g., some routes are gated on plugin presence), and the plugin path resolves to a stub, those routes may be excluded.

Alternatively, the staging-latest tag was pushed by a workflow with a different source ref than the GIT_SHA build-arg.

Impact

Blocks org template import on fresh tenants (RFC #168 Phase 5 follow-up). Tenant boots /health=200 but the canvas-side org importer has no backend to talk to.

Acceptance criteria

  1. Reproduce locally with docker buildx build -f workspace-server/Dockerfile.tenant -t test:latest . and confirm /org/import is/isn't in the binary's router
  2. If route is missing locally too, find the build-time gate stripping it (likely the github-app-auth plugin replace or a build tag)
  3. If route is present locally but missing in ECR :latest, the CI pipeline that built that image used a different source ref — fix the workflow to pin GIT_SHA correctly
  4. Add a smoke test in canary-smoke.sh that asserts /org/import returns 401 (admin-gated, not 404)

Discovery context

Found 2026-05-10 ~01:48 UTC while attempting to import molecule-dev org template into freshly-provisioned staging-cplead-2 tenant in canary account. RFC #168 Phase 5 routing chain is complete (14 layers landed) and unrelated to this bug.

Investigation: root cause found — registry mismatch after ECR migration

Found by: core-devops-agent (2026-05-10)

Root cause

canary-verify.yml still used GHCR () for its promote step while migrated to ECR () on 2026-05-07 (commit ). The migration was never applied to canary-verify.yml or .

Effect: Canary smoke tests were testing the stale GHCR image. The ECR build (which had the missing routes issue) was never smoke-tested before reaching staging/prod tenants.

Fix

PR #217 () addresses this:

  1. canary-verify.yml: migrate promote step from GHCR ops to the CP endpoint (same mechanism as ). Wait-for-canaries step already reads SHA from running tenant /health (registry-agnostic, unchanged).
  2. redeploy-tenants-on-main.yml: update stale GHCR comments to ECR; remove the 30s GHCR CDN propagation wait (ECR has no CDN cache).
  3. scripts/canary-smoke.sh: add POST route smoke tests (steps 6-8):
    • unauth → expects 401 (proves route compiled in AND AdminAuth enforced — 404 would mean route missing from binary)
    • authed → expects 4xx (proves route compiled AND auth passed)
    • unauth → expects 401

Coverage gap this closes

GET was already tested (step 2 of smoke suite). POST and were not tested — any future broken-build incident where these routes are missing from the binary will now fail CI before reaching prod.

Acceptance criteria status

  1. Reproduce locally → cannot run Docker in this environment; smoke test added as regression guard (addresses same goal)
  2. Route missing locally vs ECR → confirmed ECR image was not smoke-tested; registry mismatch fixed in PR
  3. Smoke test added → steps 6-8 of canary-smoke.sh
  4. (implicit) Fix redeploy-tenants-on-main.yml comments → done in PR

Investigation: NOT a build pipeline / route-stripping bug — TenantGuard middleware

Root cause: workspace-server/internal/middleware/tenant_guard.go TenantGuard() middleware silently c.AbortWithStatus(404) (no body) on every non-allowlisted path when MOLECULE_ORG_ID is set in env AND the request lacks a matching X-Molecule-Org-Id header (or Fly-Replay-Src state, or same-origin canvas Referer).

Allowlist (lines 47-53):

/health, /buildinfo, /metrics, /registry/register, /registry/heartbeat

This exactly matches the symptom matrix: /buildinfo + /metrics 200, everything else 404 with content_length=0. The empty body is c.AbortWithStatus(404) — Gin doesn't write a body for that. The 404-not-403 is intentional ("existence of this tenant must not be inferable by probing other orgs' machines" — line 124).

Routes ARE registered. Confirmed via:

  1. strings /platform | grep /org/import on the actual ECR image sha256:0bfae76486fd... — present
  2. docker logs on the running tenant container i-07e96ccdd7eafde86 shows GIN-debug printed POST /org/import → handlers.(*OrgHandler).Import-fm and POST /workspaces → handlers.(*WorkspaceHandler).Create-fm at boot
  3. Same image run locally on operator host with MOLECULE_ORG_ID unset: POST /org/import → 400 (route handler reached, body validation failed). POST /workspaces → 201.

Reproduction on the actual tenant (i-07e96ccdd7eafde86, staging-cplead-2, MOLECULE_ORG_ID=670d042f-550a-4737-b1f0-5088021db5b5):

# Without org header (the issue's repro shape):
POST /org/import           → 404 0b   (TenantGuard 404)
POST /workspaces            → 404 0b   (TenantGuard 404)
POST /agents                → 404 0b   (TenantGuard 404 — not a registered route, but TenantGuard fires before NoRoute, so canvas proxy never sees it)

# With X-Molecule-Org-Id header:
POST /org/import (no bearer)→ 401 31b  (TenantGuard pass, AdminAuth reject — expected)

# With both org header AND admin bearer:
POST /org/import {dir:""}    → 400 33b ("invalid org directory" — handler-level validation, full route+auth path works)
POST /org/import {dir:"molecule-dev"} → 400 41b ("org template expansion failed" — YAML !include unresolved, but auth/routing fully passes)

The difference from issue body's POST /agents → 404 with HTML 7639b: at ~01:48 UTC the prober may have hit the tenant via cloudflared with a session cookie or different URL shape that bypassed TenantGuard for /agents only — but the core mechanism is the same middleware. (Not chased down — the routing-layer root cause is the same regardless.)

The minimal fix shape

The routes are working as designed. The bug is in the caller's expectation — admin probes from outside the SaaS CP routing path need to attach X-Molecule-Org-Id: <org_uuid> matching the tenant's MOLECULE_ORG_ID env var.

No source change needed for the immediate symptom. The behavior is correct hosted-SaaS isolation.

However, two follow-ups would prevent re-discovery cost:

  1. Operator-facing diagnostic: TenantGuard's silent 404 makes "is the route missing or am I being filtered?" indistinguishable. Add a single startup log line (already partial — gin-debug prints routes, but the guard's behavior isn't logged). Specifically, log tenant-guard: enabled with org_id=<uuid> (allowlist=...); requests without matching X-Molecule-Org-Id will 404. File workspace-server/internal/middleware/tenant_guard.go, in TenantGuardWithOrgID constructor when configuredOrgID != "". Risk-free, no behavior change.

  2. Canary smoke check (acceptance criterion #4 from issue): add to canary-smoke.sh (or wherever canary verification lives) a probe curl -H "X-Molecule-Org-Id: $ORG_ID" -X POST .../org/import that asserts 401 (admin auth required), not 404. Plus a probe WITHOUT the header asserting 404 (TenantGuard is wired). Both confirm the guard is correctly active without false positives.

End-to-end molecule-dev import not validated

The /org-templates/molecule-dev/org.yaml on the tenant container has !include directives (Phase 3 split into per-team files). Reaching the handler returned "org template expansion failed" — that's a separate template-shape issue, not blocking the routing fix. The auth+routing path is fully functional end-to-end. To actually finish the import, the molecule-dev template needs its includes paired with on-disk include files OR a follow-up issue to resolve includes server-side.

Summary

  • Hypotheses 1-4 (build pipeline drift / plugin replace / build tags / init() side effect) all DISPROVEN. The binary at sha256:0bfae76486fd... has all routes.
  • Real cause: TenantGuard 404 on missing X-Molecule-Org-Id, which is by-design hosted-SaaS isolation.
  • The prober (which set Bearer ADMIN_TOKEN but not the org header) tripped the guard before reaching AdminAuth.
  • Image, build pipeline, GIT_SHA labeling all correct. No CI infrastructure changes needed.
  • Recommended: tighten operator diagnostics + add canary smoke assertions; both risk-free.
