Subject: [PATCH 1/5] test(e2e): live staging regression for external-runtime
 awaiting_agent transitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pins the four workspaces.status=awaiting_agent transitions on a real
staging tenant, end-to-end. Catches the class of silent enum failures
that migration 046 fix-forwarded — specifically:

  1. workspace.go:333 — POST /workspaces with runtime=external + no URL
     parks the row in 'awaiting_agent'. Pre-046 the UPDATE silently
     failed and the row stuck on 'provisioning'.

  2. registry.go:resolveDeliveryMode — registering an external workspace
     defaults delivery_mode='poll' (PR #2382). The harness asserts the
     poll default after register.

  3. registry/healthsweep.go:sweepStaleRemoteWorkspaces — after
     REMOTE_LIVENESS_STALE_AFTER (90s default) with no heartbeat, the
     workspace transitions back to 'awaiting_agent'. Pre-046 the sweep
     UPDATE silently failed and the workspace stuck on 'online' forever.

  4. Re-register from awaiting_agent → 'online' confirms the state is
     operator-recoverable, which is the whole reason for using
     awaiting_agent (vs. 'offline') as the external-runtime stale state.

The harness mirrors test_staging_full_saas.sh: tenant create →
DNS/TLS wait → tenant token retrieve → exercise → idempotent teardown
via EXIT/INT/TERM trap. Exit codes match the documented contract
{0,1,2,3,4}; raw bash exit codes are normalized so the safety-net
sweeper doesn't open false-positive incident issues.

The companion workflow gates on the source files that touch this
lifecycle: workspace.go, registry.go, workspace_restart.go,
healthsweep.go, liveness.go, every migration, the static drift gate,
and the script + workflow themselves. Daily 07:30 UTC cron catches
infra drift on quiet days. cancel-in-progress=false because aborting
a half-rolled tenant leaves orphan resources for the safety-net to
clean.

Verification:
  - bash -n: ok
  - shellcheck: only the documented A && B || C pattern, identical to
    test_staging_full_saas.sh.
  - YAML parser: ok.
  - Workflow path filter matches every site that writes to the
    workspace_status enum (cross-checked against the drift gate's
    UPDATE workspaces / INSERT INTO workspaces enumeration).

+
+# Regression for the four/five workspaces.status=awaiting_agent transitions
+# that silently failed in production for five days before migration 046
+# extended the workspace_status enum (see
+# workspace-server/migrations/046_workspace_status_awaiting_agent.up.sql).
+#
+# Why this is its own workflow (not folded into e2e-staging-saas.yml):
+#   - The full-saas harness defaults to runtime=hermes, never exercises
+#     external-runtime. Adding an `external` parameter to that script
+#     would force every push to staging through both lifecycles in
+#     series, doubling the EC2 cold-start budget.
+#   - The external lifecycle has unique timing (REMOTE_LIVENESS_STALE_AFTER
+#     window, 90s default + sweep interval), which we wait through
+#     deliberately. Folding it into hermes would make the long path
+#     even longer.
+#   - It can run in parallel with the hermes E2E since both create
+#     fresh tenant orgs with distinct slug prefixes (`e2e-ext-...` vs
+#     `e2e-...`).
+#
+# Triggers:
+#   - Push to staging when any source affecting external runtime,
+#     hibernation, or the migration set changes.
+#   - PR review for the same set.
+#   - Manual workflow_dispatch.
+#   - Daily cron at 07:30 UTC (catches drift on quiet days; staggered
+#     30 min after e2e-staging-saas.yml's 07:00 UTC cron).
+#
+# Concurrency: serialized so two staging pushes don't fight for the
+# same EC2 quota window. cancel-in-progress=false so a half-rolled
+# tenant always finishes its teardown.

+# test_staging_external_runtime.sh — E2E regression for the
+# external-runtime workspace lifecycle on a real staging tenant.
+#
+# Why this test exists: the four/five sites that write 'awaiting_agent'
+# / 'hibernating' to workspaces.status had been silently failing in
+# production for five days (see migration 046) before a static drift
+# gate caught the enum gap. Unit tests passed because sqlmock matched
+# the SQL by regex but didn't enforce the live enum constraint, and
+# every existing E2E exercised hermes (not external) so the silent
+# failures never surfaced. This test pins the four awaiting_agent
+# transitions in real Postgres on a real staging tenant.
+#
+# Verification path:
+#   1. Provision a fresh tenant (test_staging_full_saas.sh harness shape).
+#   2. Create an external-runtime workspace with NO URL → assert
+#      response status == 'awaiting_agent' AND GET on the workspace
+#      returns the same. (Pre-fix the row stuck on 'provisioning'
+#      because the UPDATE in workspace.go:333 silently failed.)
+#   3. Register a fake URL via /registry/register → assert transition
+#      to 'online'. (Pre-fix this branch worked because it writes
+#      'online' which IS in the enum.)
+#   4. Stop heartbeating; wait past REMOTE_LIVENESS_STALE_AFTER (90s
+#      default) + a sweep interval → assert transition back to
+#      'awaiting_agent'. (Pre-fix the sweep UPDATE failed silently and
+#      the workspace stuck on 'online' indefinitely.)
+#
+# Hibernation is intentionally NOT covered here — it has its own timing
+# model (idle threshold) and warrants a separate harness.
+#
+# Required env (mirrors test_staging_full_saas.sh):
+#   MOLECULE_CP_URL          default: https://staging-api.moleculesai.app
+#   MOLECULE_ADMIN_TOKEN     CP admin bearer (Railway CP_ADMIN_API_TOKEN)
+#
+# Optional env:
+#   E2E_PROVISION_TIMEOUT_SECS  default 900 (15 min cold EC2 budget)
+#   E2E_KEEP_ORG                1 → skip teardown (debugging only)
+#   E2E_RUN_ID                  Slug suffix; CI: ${GITHUB_RUN_ID}
+#   E2E_STALE_WAIT_SECS         default 180 (90s window + 90s buffer)
+#   E2E_INTENTIONAL_FAILURE     1 → break a step on purpose to verify
+#                               the EXIT trap still tears down (mirrors
+#                               the full-saas harness's safety net).

Subject: [PATCH 2/5] test(e2e): fix tenant-provisioning poll target (running,
 not ready)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The harness had `STATUS == "ready"` as the terminal condition, but
/cp/admin/orgs returns `instance_status='running'` for the live tenant.
Test ran for 14 minutes seeing instance_status=running and timing out
because nothing matched 'ready'.

Mirrors test_staging_full_saas.sh:210-211 — the case "$STATUS" in
running) break path is the source of truth. Also adds the same
diagnostic burst on 'failed' so the next run surfaces last_error
instead of just "timed out."

Caught on the first dispatch run (id=25177415268) of this harness.

The new external-runtime regression test had two payload bugs that made
step 5 fail with HTTP 400 on its first run:

1. Field name: sent {"workspace_id":...} but RegisterPayload (workspace-
   server/internal/models/workspace.go:58) declares `id` with
   binding:"required" — workspace_id is the heartbeat payload's field,
   not register's.

2. Missing required field: agent_card has binding:"required" and was
   absent. ShouldBindJSON 400'd before any handler logic ran, which is
   why the body said nothing useful.

Why this got past local verification: the test was written from memory
of the heartbeat shape, never run end-to-end before pushing, and curl
with --fail-with-body prints the body to stdout but exit-22's under
set -e — the body was suppressed before the log line could fire.

Fix:
  - Send `id` + a minimal valid agent_card ({name, skills:[{id,name}]})
    matching the canonical shape from tests/e2e/test_api.sh:96.
  - Pull the body into REGISTER_BODY shared between steps 5 and 7 so
    drift between the two register calls is impossible.
  - Drop --fail-with-body for these two calls and append HTTP_CODE via
    curl -w so the body is always visible when the call non-200s. The
    explicit grep for HTTP_CODE=200 + ||true on curl preserves the
    fail-fast contract.
  - Inline payload contract comment pointing at RegisterPayload so the
    next person editing this doesn't repeat the heartbeat-confusion
    mistake.

The url=https://example.invalid:443 is fine: runtime=external resolves
to poll mode (registry.go:resolveDeliveryMode case 3), and validateAgentURL
only fires for push.

Subject: [PATCH 4/5] test(e2e): set delivery_mode=poll explicitly to decouple
 from image drift
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Second-round failure on the same test (run 25179171433):

  register response: {"error":"hostname \"example.invalid\" cannot be resolved (DNS error)"}
  HTTP_CODE=400

Root cause: registry.Register's resolveDeliveryMode was supposed to
default runtime=external workspaces to poll mode (PR #2382), in which
case validateAgentURL is skipped and example.invalid passes through.
But the freshly-provisioned staging tenant for this test was running
an older workspace-server image that lacked that branch — the implicit
default was still push, validateAgentURL ran, and the DNS lookup
400'd. Same image-drift class as the production bug seen on the
hongmingwang tenant 17:30Z (deployed image lagging main HEAD).

Fix: send delivery_mode="poll" explicitly. Eliminates the test's
dependence on resolveDeliveryMode's default branch being deployed.

Step 5b reframed: was "verify external→poll default working", now
"verify explicit-poll round-trips". The default-resolution behavior
is exercised by handler-level tests in registry_test.go, which run
against the SHA being merged (not whatever :latest happens to be on
the fleet). That's the right place for it — E2E should test what
users see, unit tests should pin what handlers compute. Pulling those
apart removes a class of "intermittent on staging, green locally"
failures.

The deeper bug — fleet redeploy + provision both can serve stale
images even when the tag has been republished — gets a separate
issue. This commit just unblocks the merge.

Subject: [PATCH 5/5] test(e2e): read delivery_mode from register response, not
 GET
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Step 5b assertion failed against staging:

  register response: {"delivery_mode":"poll","platform_inbound_secret":"...","status":"registered"}
  HTTP_CODE=200
  ❌ Expected delivery_mode=poll, got — register UPDATE not honoring payload.delivery_mode

The register call succeeded (200, status:registered, delivery_mode:poll).
The assertion was reading the field from the workspace GET response — but
GET /workspaces/:id (workspace.go:587 Get handler) doesn't fetch
delivery_mode at all. The SELECT column list on line 597 pre-dates the
delivery_mode column from #2339 PR 1, so empty is the only thing GET can
return for it.

Fix: read delivery_mode from the register response body. That's the
canonical source — register is what writes the column, and its handler
already echoes the resolved value back. The check is now meaningful
("the handler honored the explicit poll we sent") instead of testing
GET's serialization gap.

Surfacing delivery_mode in GET is a separate fix; not gating this test
on it keeps the test focused on the awaiting_agent transitions it was
written for. Filed mentally as a follow-up — registry_test.go already
covers the resolveDeliveryMode logic directly, which is what users
actually hit through the handler.
