tool_delegate_task was POSTing directly to peer["url"], which is
the Docker-internal hostname (e.g. http://ws-X-Y:8000) for in-
container peers. External callers — the standalone molecule-mcp
wrapper running on an operator's laptop — get [Errno 8] nodename
nor servname every single delegation, breaking the universal-MCP
path's last "ride the same code as in-container" claim.
The platform's /workspaces/:peer-id/a2a proxy endpoint already
handles internal forwarding for in-container peers AND is the only
path external runtimes can use. Unify on it: in-container callers
pay one extra HTTP hop on the same Docker bridge (microseconds);
external callers get a working delegation path for the first time.
discover_peer is still called for access-control + online-status
detection — only the routing target changes. Verified live on

CodeQL flagged the bare `assert state.pop(...) is None` — under
`python -O` asserts are stripped, which would skip the call entirely
and the test would silently pass without exercising the code. Bind
the result first so the call always runs.

The universal MCP server (a2a_mcp_server.py) was outbound-only — agents
in standalone runtimes (Claude Code, hermes, codex, etc.) could
delegate, list peers, and write memories, but never observed the
canvas-user or peer-agent messages addressed to them. This blocked
"constantly responding" loops without forcing operators back onto a
runtime-specific channel plugin.
This PR closes the inbound gap with a poller-fed in-memory queue and
three new MCP tools:
- wait_for_message(timeout_secs?) — block until next message arrives
- inbox_peek(limit?) — list pending messages (non-destructive)
- inbox_pop(activity_id) — drop a handled message
A daemon thread polls /workspaces/:id/activity?type=a2a_receive every
5s, fills the queue from the cursor (since_id), and persists the cursor
to ${CONFIGS_DIR}/.mcp_inbox_cursor so a restart doesn't replay backlog.
On 410 (cursor pruned) we fall back to since_secs=600 for a bounded
recovery window. Activity-row → InboxMessage extraction mirrors the
molecule-mcp-claude-channel plugin's extractText (envelope shapes #1-3
+ summary fallback).
mcp_cli.main starts the poller alongside the existing register +
heartbeat threads. In-container runtimes (which have push delivery via
canvas WebSocket) skip activation, so inbox tools return an
informational "(inbox not enabled)" message instead of double-delivery.

Critical:
- ExternalConnectModal.tsx: filledUniversalMcp substitution searched
for WORKSPACE_AUTH_TOKEN but the snippet's placeholder is now
MOLECULE_WORKSPACE_TOKEN (changed in the previous polish commit
876c0bfc). Operators copy-pasting the MCP tab would have gotten a
literal "<paste from create response>" instead of the token. Fix
the substitution to match the new placeholder name.
Important:
- mcp_cli._platform_register: 401/403 from initial register now hard-
exits with code 3 + an actionable stderr message pointing the
operator at the canvas Tokens tab. Pre-fix: warning log + continue,
which made a bad-token startup silently fail (heartbeat 401's
forever, every tool call also 401's, no clear surfacing in the
operator's MCP client). 500/503 still log + continue (transient
platform blips shouldn't abort the MCP loop).
- a2a_mcp_server.cli_main docstring: removed stale claim that this is
the wheel's console-script entry-point target. The actual target is
mcp_cli.main since 2026-04-30. Wheel-smoke pins both names so the
functionality was correct, but the doc was lying.
Test coverage: 3 new mcp_cli tests:
- register 401 exits code=3 + stderr mentions canvas Tokens tab
- register 403 (C18 hijack rejection) takes same path
- register 500/503 does NOT exit — only auth errors hard-fail
Findings deferred to follow-up (acceptable per review rubric):
- Code dedup across mcp_cli / heartbeat.py / molecule_agent SDK
- Pooled httpx.Client for connection reuse
- Heartbeat exponential backoff
- Token-resolution ordering parity (env-first vs file-first)
between mcp_cli.main and platform_auth.get_token

The canvas tab snippet for the Universal MCP path was written before
this PR added the built-in register + heartbeat thread. Earlier wording
described it as "outbound-only — pair with the Claude Code or Python SDK
tab for heartbeat + inbound messages" — that's stale. molecule-mcp now
handles register + heartbeat itself; the only thing it doesn't yet do is
inbound A2A delivery.
Updated:
- externalUniversalMcpTemplate header comment + body — describes
standalone behavior, points operators at SDK/channel only when they
need INBOUND (not heartbeat).
- Drops the now-redundant curl-register step from the snippet — the
binary registers itself on startup.
- Canvas modal label likewise updated.
No runtime / behavior change; pure docs polish so a copy-pasting
operator's mental model matches what the binary actually does.

Two paired fixes that together let an external operator run a single
process (molecule-mcp) and see their workspace come up online in the
canvas — the bug surfaced live when status stuck at "awaiting_agent /
OFFLINE" despite an active MCP server.
Platform side (workspace-server/internal/handlers/registry.go):
Heartbeat handler already auto-recovers offline → online and
provisioning → online, but NOT awaiting_agent → online. Healthsweep
flips stale-heartbeat external workspaces TO awaiting_agent, and
with no recovery path the workspace stays "OFFLINE — Restart" in the
canvas forever. Add the symmetric branch: if currentStatus ==
"awaiting_agent" and a heartbeat arrives, flip to online + broadcast
WORKSPACE_ONLINE. Mirrors the existing offline/provisioning patterns
exactly. Test: TestHeartbeatHandler_AwaitingAgentToOnline asserts
the SQL UPDATE fires with the awaiting_agent guard clause.
Wheel side (workspace/mcp_cli.py):
molecule-mcp was outbound-only — operators had to run a separate
SDK process to register + heartbeat. Now mcp_cli.main():
1. Calls /registry/register at startup (idempotent upsert flips
status awaiting_agent → online via the existing register path).
2. Spawns a daemon thread that POSTs /registry/heartbeat every
20s. 20s is comfortably under the healthsweep stale window so
a single missed beat doesn't cause status churn.
3. Runs the MCP stdio loop in the foreground.
Both calls set Origin: ${PLATFORM_URL} so the SaaS edge WAF accepts
them. Threaded heartbeat (not asyncio) chosen because it doesn't
need to share an event loop with the MCP stdio server — daemon=True
cleanly dies when the operator's runtime exits.
MOLECULE_MCP_DISABLE_HEARTBEAT=1 escape hatch lets in-container
callers (which have heartbeat.py running already) reuse the entry
point without double-heartbeating. Default is enabled.
End-to-end verification (live, against
hongmingwang.moleculesai.app, workspace 8dad3e29-...):
pre-fix: status=awaiting_agent → canvas shows OFFLINE forever
post-fix: ran `molecule-mcp` for 5s standalone → canvas state:
status=online runtime=external agent=molecule-mcp-8dad3e29
Test coverage: 7 new mcp_cli tests (register-at-startup, heartbeat-
thread-spawned, disable-env-skips-both, env-and-file token resolution,
register payload shape, heartbeat endpoint + headers); 1 new platform
test (awaiting_agent → online recovery). Full workspace + handlers
suites green: 1355 Python, full Go handlers passing.

The "Connect your external agent" dialog already covered Claude Code,
Python SDK, curl, and raw fields. This adds a Universal MCP tab that
documents the new \`molecule-mcp\` console script — the runtime-
agnostic baseline shipped by PR #2413's workspace-runtime changes.
Surface area:
- New \`externalUniversalMcpTemplate\` constant in workspace-server.
Three-step snippet: pip install runtime → one-shot register via curl
→ wire molecule-mcp into agent's MCP config (Claude Code example,
notes that hermes/codex/etc. take the same env-var contract).
- Workspace create response now includes \`universal_mcp_snippet\`
alongside the existing curl/python/channel snippets.
- Canvas modal renders the tab when \`universal_mcp_snippet\` is
present; backward-compatible with older platform builds (tab hides
when empty).
Origin/WAF coverage (the user explicitly asked for this):
- The runtime wheel handles Origin automatically (this PR's earlier
commit on platform_auth.auth_headers).
- The curl tab now sets \`Origin: {{PLATFORM_URL}}\` preemptively
with an explanatory comment; \`/registry/register\` is currently
WAF-allowed without it but adding now keeps the snippet working
if WAF rules expand. The comment also explains why
\`/workspaces/*\` paths return empty 404 without Origin — the
exact failure mode I hit while smoke-testing this PR live.
- The MCP snippet's footer notes that the wheel auto-handles
Origin so operators don't think about it.
End-to-end verification (against live tenant
hongmingwang.moleculesai.app, freshly registered workspace):
- get_workspace_info → full JSON
- list_peers → "Claude Code Agent (ID: 97ac32e9..., status: online)"
- recall_memory → "No memories found."
all returned by the molecule-mcp binary speaking MCP stdio to
this Claude Code session.

Discovered while smoke-testing the molecule-mcp external-runtime path
against a live tenant (hongmingwang.moleculesai.app). Every tool call
that hit /workspaces/* or /registry/*/peers returned 404 — but
/registry/register and /registry/heartbeat returned 200. Diagnosis:
the tenant's edge WAF requires a same-origin header. Without it,
unhandled paths get silently rewritten to the canvas Next.js app,
which has no /workspaces or /registry/:id/peers route and returns an
empty 404. The molecule-mcp-claude-channel plugin already sets this
header (server.ts:271-276); the workspace runtime never did because
in-container PLATFORM_URLs (Docker network) aren't behind the WAF.
Fix: extend platform_auth.auth_headers() to include
Origin: ${PLATFORM_URL} whenever PLATFORM_URL is set. Inside-container
behavior is unchanged (the WAF is path-irrelevant for the internal
hostnames). External-runtime calls now thread the WAF correctly.
Verification (live, against a freshly-registered external workspace):
pre-fix: get_workspace_info → "not found", list_peers → 404
post-fix: get_workspace_info → full workspace JSON,
list_peers → "Claude Code Agent (ID: 97ac32e9..., status: online)"
This is the kind of bug unit tests can never catch — caught only by
running the wheel against the real tenant. Memory:
feedback_always_run_e2e.md.
Test coverage: 4 new tests in test_platform_auth.py — Origin alone
when no token + Origin + Authorization both, no-PLATFORM_URL falls
through to original empty-dict behavior, env-token path with Origin.

Ship the baseline universal MCP path that any external runtime (Claude
Code, hermes, codex, anything that speaks MCP stdio) can use, before
optimizing per-runtime channels. Today the workspace MCP server only
spins up inside the container; external operators have no way to call
the 8 platform tools (delegate_task, list_peers, send_message_to_user,
commit_memory, etc.) from outside.
Three additive changes:
1. **`platform_auth.get_token()` env-var fallback** — adds
`MOLECULE_WORKSPACE_TOKEN` as a fallback when no
`${CONFIGS_DIR}/.auth_token` file exists. File-first preserves
in-container behavior unchanged. External operators (no /configs
volume) now have a way to supply the token without faking the
filesystem layout.
2. **`molecule-mcp` console script** — adds a new entry point in the
published `molecule-ai-workspace-runtime` PyPI wheel. Operators run
`pip install molecule-ai-workspace-runtime`, set 3 env vars
(WORKSPACE_ID, PLATFORM_URL, MOLECULE_WORKSPACE_TOKEN), and register
the binary in their agent's MCP config. `mcp_cli.main` is a thin
validator wrapper — it checks env BEFORE importing the heavy
`a2a_mcp_server` module so a misconfigured first-run gets a friendly
3-line error instead of a 20-line module-level RuntimeError
traceback.
3. **Wheel smoke gate** — extends `scripts/wheel_smoke.py` to assert
`cli_main` and `mcp_cli.main` are importable. Same regression class
as the 0.1.16 main_sync incident: a silent rename or unrewritten
import here would break every external operator on the next wheel
publish (memory: feedback_runtime_publish_pipeline_gates.md).
Test coverage:
- `tests/test_platform_auth.py` — 8 new tests for the env-var fallback:
file-priority, env-fallback, whitespace handling, cache, header
construction, empty-env-as-unset.
- `tests/test_mcp_cli.py` — 8 new tests for the validator: each
required var separately, file-or-env satisfies token requirement,
whitespace-only env treated as missing, help mentions canvas Tokens
tab.
- Full `workspace/tests/` suite green: 1346 passed, 1 skipped.
- Local end-to-end: built wheel, installed in venv, ran `molecule-mcp`
with no env → friendly error; with env → MCP server starts.
Why now / why this shape: user redirect was "support the baseline
first so all runtimes can use, then optimize". A claude-only MCP
channel leaves hermes/codex/third-party operators broken on
runtime=external. This PR ships the runtime-agnostic baseline; per-
runtime polish (claude-channel push delivery, hermes-native
bindings) is a follow-up PR. PR #2412 fixed the partner bug where
canvas Restart silently revoked the operator's token — the two
together unblock the external-runtime story end-to-end.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
POST /workspaces/:id/restart on a runtime=external workspace ran the full
re-provision pipeline (Stop → provisionWorkspace*), which calls
issueAndInjectToken → RevokeAllForWorkspace. For external workspaces
(operator-driven, no container/EC2) that silently destroyed the operator's
local bearer token on every "Restart" click in the canvas — the local
poller would then 401-spam against /activity until the operator manually
regenerated from the Tokens tab.
The auto-restart path (runRestartCycle, line 436) already short-circuits
runtime=external. This patch mirrors that for the manual handler so the
two paths agree, and surfaces a 200 OK with a clear message so the
canvas can tell the operator the fix is on their side rather than
silently no-op'ing.
Test coverage: TestRestartHandler_ExternalRuntimeNoOps asserts the
short-circuit fires *before* any DB write or provision call. sqlmock's
"unexpected query" failure mode would catch a regression that
re-introduced the token revoke or the status=provisioning UPDATE.

peer-discovery-404 imports workspace/a2a_client.py which depends on
httpx; the runner's stock Python doesn't have it, so the replay's
PARSE assertion (b) fails with ModuleNotFoundError on every run. The
WIRE assertion (a) — pure curl — passes, so the failure was masking
just enough to make the replay LOOK partially-broken when the tenant
side is fine.
Adding tests/harness/requirements.txt with only httpx instead of
sourcing workspace/requirements.txt: that file pulls a2a-sdk,
langchain-core, opentelemetry, sqlalchemy, temporalio, etc. — ~30s
of install for one replay's PARSE step. The harness's deps surface
should grow when a new replay introduces a new import, not by
default.
Workflow gains one step (`pip install -r tests/harness/requirements.txt`)
between the /etc/hosts setup and run-all-replays. No other changes.
Replaces the hardcoded base64 sentinel (630dd0da) with a per-run
generation in up.sh, exported into compose's interpolation environment.
Why:
- Hardcoding a 32-byte base64 string in the repo, even one labelled
"test-only", sets a bad muscle-memory pattern. The next agent or
contributor copies the shape into another harness — or worse, into a
staging .env — and the test-only sentinel turns into something
someone treats as a real key.
- Secret scanners flag key-shaped values regardless of the surrounding
comment claiming intent. Avoiding the literal entirely sidesteps the
false-positive.
- A fresh key per harness lifetime more closely mimics prod's
per-tenant isolation, exercising the same code paths without any
pretense of stable encrypted-data fixtures (which the harness wipes
on every ./down.sh anyway).
Implementation:
- up.sh: `openssl rand -base64 32` if SECRETS_ENCRYPTION_KEY isn't
already set in the caller's env. Honoring a pre-set value lets a
debug session pin a key for reproducibility (e.g. when investigating
encrypted-row corruption).
- compose.yml: `${SECRETS_ENCRYPTION_KEY:?…}` makes a misuse loud —
running `docker compose up` directly bypassing up.sh fails fast with
a clear error pointing at the right entry point, rather than a 100s
unhealthy-tenant timeout.
Both paths verified via `docker compose config`:
- with key exported: value interpolates cleanly
- without it: "required variable SECRETS_ENCRYPTION_KEY is missing a
value: must be set — run via tests/harness/up.sh, which generates
one per run"
Found via the first run of the harness-replays-required-check workflow
(#2410): the tenant container failed its healthcheck after 100s with
"refusing to boot without encryption in production". This is the
deferred CRITICAL flagged on PR #2401 — `crypto.InitStrict()` requires
SECRETS_ENCRYPTION_KEY when MOLECULE_ENV=production, and the harness
sets prod-mode but never seeded a key.
Fix: add a clearly-test 32-byte base64 value (encoding the literal
string "harness-test-only-not-for-prod!!") inline. Keeping
MOLECULE_ENV=production preserves the harness's value as a production-
shape replay surface — it now exercises the full encryption boot path
including the strict check, rather than skirting it via dev-mode.
Why inline rather than .env:
- The harness compose file is meant to be self-contained and
reproducible from a clean clone. An external .env would split the
config across two files for one synthetic value.
- The value is intentionally a sentinel; there's no operator decision
here to gate behind a per-deployment file.
After this lands the harness boots clean and `run-all-replays.sh` can
exercise the buildinfo + peer-discovery replays as designed. The
required-check workflow itself (#2410) needs no change.
First run on PR #2410 failed with 'container harness-tenant-1 is unhealthy'
but the dump-compose-logs step printed empty tenant logs because
run-all-replays.sh's trap-on-EXIT had already torn down the harness.
Setting KEEP_UP=1 leaves containers in place; the always-run Force
teardown step at the end owns cleanup explicitly. Now we'll actually
see why the tenant didn't become healthy.

Iterates a list of tenant slugs (default canary set on production,
operator-supplied on staging), curls each tenant's /buildinfo plus
canvas's /api/buildinfo, compares to origin/main's HEAD SHA, prints a
table with one of {current, stale, unreachable} per surface. Returns
non-zero if any surface is stale, so it can be wired into a periodic
alert later.
Why this exists: every "is the fix live?" question used to be
answered with a one-off curl + git rev-parse + manual diff. This
script does that uniformly across every public surface (workspace
tenants + canvas) and is parseable. The redeploy verifier (#2398)
covers the deploy moment; this covers any-time-after.
Reads EXPECTED_SHA from `gh api repos/Molecule-AI/molecule-core/
commits/main` so it always reflects the actual upstream tip, not
local working-copy state. Falls back to local origin/main with a
WARN if `gh` isn't logged in — debugging is still useful even if
the comparison may lag.
Depends on:
- #2409 (TenantGuard /buildinfo allowlist) — without it every
tenant looks "unreachable" because the route 404s before the
handler. Already merged on staging; will hit production after
the next staging→main fast-forward + redeploy.
- #2407 (canvas /api/buildinfo) — already on main + Vercel.
Usage:
./scripts/ops/check-prod-versions.sh # production canary set
TENANT_SLUGS="a b c" ./scripts/ops/check-prod-versions.sh # custom set
ENV=staging TENANT_SLUGS="..." ./scripts/ops/check-prod-versions.sh

Closes the gap between "the harness exists" and "the harness blocks bugs."
Phase 2 of the harness roadmap (per tests/harness/README.md): make
harness-based E2E a required CI check on every PR touching the tenant
binary or the harness itself.
Trigger: push + pull_request to staging+main, paths-filtered to
workspace-server/**, canvas/**, tests/harness/**, and this workflow.
merge_group support included so this becomes branch-protectable.
Single-job-with-conditional-steps pattern (matches e2e-api.yml). One
check run regardless of paths-filter outcome; satisfies branch
protection cleanly per the PR #2264 SKIPPED-in-set finding.
Why this exists: 2026-04-30 we shipped a TenantGuard allowlist gap
(/buildinfo added to router.go in #2398, never added to the allowlist)
that the existing buildinfo-stale-image.sh replay would have caught.
The harness was wired correctly; nobody ran it. Replays as a discipline
beat replays as a memory item.
The CI pipeline:
detect-changes (paths filter)
└ harness-replays (always)
├ no-op pass when paths-filter says no relevant change
└ otherwise: checkout + sibling plugin checkout +
/etc/hosts entry + run-all-replays.sh +
compose-logs-on-failure + force-teardown
Compose logs from tenant/cp-stub/cf-proxy/postgres are dumped on
failure so a CI red is debuggable without re-reproducing locally.
The trap in run-all-replays.sh handles teardown; the always-run
down.sh step is a belt-and-suspenders against trap-bypass kills.
Follow-ups (not in this PR):
- Add this check to staging branch protection once it's been green
for a few PRs (the new-workflow-instability hedge that other gates
followed).
- Eventually wire the buildx GHA cache to speed up tenant image
builds — currently every PR rebuilds the full Dockerfile.tenant
(Go + Next.js + template clones) from scratch. Acceptable for now;
optimize when the timeout-minutes:30 ceiling becomes painful.

The /buildinfo route added in #2398 to verify each tenant runs the
published SHA was 404'd by TenantGuard on every production tenant —
the allowlist had /health, /metrics, /registry/register,
/registry/heartbeat, but not /buildinfo. The redeploy workflows
curl /buildinfo from a CI runner with no X-Molecule-Org-Id header,
TenantGuard 404'd them, gin's NoRoute proxied to canvas, canvas
returned its HTML 404 page, jq read empty git_sha, and the verifier
silently soft-warned every tenant as "unreachable" — which the
workflow doesn't fail on.
Confirmed externally:
curl https://hongmingwang.moleculesai.app/buildinfo
→ HTTP 404 + Content-Type: text/html (Next.js "404: This page
could not be found.") even though /health on the same host
returns {"status":"ok"} from gin.
The buildinfo package's own doc already declares /buildinfo public
by design ("Public is intentional: it's a build identifier, not
operational state. The same string is already published as
org.opencontainers.image.revision on the container image, so no new
info is exposed.") — the allowlist just missed it.
Pin the alignment in tenant_guard_test.go:
TestTenantGuard_AllowlistBypassesCheck now asserts /buildinfo
returns 200 without an org header alongside /health and /metrics,
so a future allowlist edit can't silently regress the verifier
again.
Closes the silent-success failure mode: stale tenants will now
show up as STALE (hard-fail) rather than UNREACHABLE (soft-warn).

Pre-fix, cmd/server/main.go gated the entire health-sweep goroutine on
`prov != nil`. On SaaS tenants (`MOLECULE_ORG_ID` set) the local Docker
provisioner is never initialized — only `cpProv`. So the goroutine
never started, and `sweepStaleRemoteWorkspaces` (which transitions
runtime='external' workspaces from 'online' to 'awaiting_agent' when
their last_heartbeat_at goes stale) never ran.
Net effect on production: every external-runtime workspace on SaaS
that lost its agent stayed 'online' indefinitely instead of falling
back to 'awaiting_agent' (re-registrable). The drift gate (#2388)
caught the migration side and #2382 fixed the SQL writes, but this
orchestration-side gate slipped through both because there was no
SaaS-mode E2E coverage on the heartbeat-loss → awaiting_agent
transition.
Caught by #2392 (live staging external-runtime regression E2E)
failing at step 6 — 180s with no heartbeat, expected
status=awaiting_agent, got online.
Fix: drop the `if prov != nil` gate. `StartHealthSweep` already
handles nil checker correctly (healthsweep.go:50-71): the Docker
sweep is gated inside the loop, the remote sweep always runs. Test
coverage already exists at TestStartHealthSweep_NilCheckerRunsRemoteSweep.
After this lands and tenants redeploy, #2392 step 6 passes and the
regression coverage closes.

Workspace-server has GET /buildinfo (PR #2398) — `curl https://<slug>.
moleculesai.app/buildinfo` returns the live git SHA. Canvas had no
parallel: debugging "is this the deployed code?" required reading
Vercel's UI or response headers (deployment ID, not git SHA).
Add canvas /api/buildinfo returning {git_sha, git_ref, vercel_env}
sourced from VERCEL_GIT_COMMIT_SHA / _REF / VERCEL_ENV — Vercel injects
these at build time from the deploying commit. Outside Vercel (local
`next dev`, harness) all three are unset and the endpoint returns
`git_sha: "dev"`, the same sentinel workspace-server uses pre-ldflags-
injection.
Now both surfaces speak the same vocabulary:
curl https://<slug>.moleculesai.app/buildinfo
curl https://canvas.moleculesai.app/api/buildinfo
3 tests cover dev-fallback, Vercel-injected SHA pass-through, and JSON
content type.

Boots the harness, runs every script under replays/, tracks pass/fail,
and tears down on exit. Closes the README's TODO for the harness runner
that the per-replay-registration comment referenced.
Usage:
./run-all-replays.sh # boot, run, teardown
KEEP_UP=1 ./run-all-replays.sh # leave harness running on exit
REBUILD=1 ./run-all-replays.sh # rebuild images before booting
Trap-on-EXIT teardown ensures partial-failure runs don't leak Docker
resources. Returns non-zero if any replay failed; CI can adopt this as
a single command without per-replay registration. Phase 2 picks this up
to wire harness-based E2E as a required check.

publish-runtime.yml had a broad smoke (AgentCard call-shape, well-known
mount alignment, new_text_message) inline as a heredoc. runtime-prbuild-
compat.yml had a narrow inline smoke (just `from main import main_sync`).
Result: a PR could introduce SDK shape regressions that pass at PR time
and only fail at publish time, post-merge.
Extract the broad smoke into scripts/wheel_smoke.py and invoke it from
both workflows. PR-time gate now matches publish-time gate — same script,
same assertions. Eliminates the drift hazard of two heredocs that have
to be kept in lockstep manually.
Verified locally:
* Built wheel from workspace/ source, installed in venv, ran smoke → pass
* Simulated AgentCard kwarg-rename regression → smoke catches it as
`ValueError: Protocol message AgentCard has no "supported_interfaces"
field` (the exact failure mode of #2179 / supported_protocols incident)
Path filter for runtime-prbuild-compat extended to include
scripts/wheel_smoke.py so smoke-only edits get PR-validated. publish-
runtime path filter intentionally NOT extended — smoke-only edits should
not auto-trigger a PyPI version bump.
Subset of #131 (the broader "invoke main() against stub config" goal
remains pending — main() needs a config dir + stub platform server).

Self-review of #2403 caught a regression: with a 1-tenant fleet (the
exact case the original #2402 fix targeted), the new floor would
re-introduce the flake. Trace:
TOTAL=1, UNREACHABLE=1, $((1/2))=0
if 1 -gt 0 → TRUE → exit 1
The 50%-rule only meaningfully distinguishes "real outage" from
"teardown race" when the fleet is large enough that "half down" is
statistically meaningful. With 1-3 tenants, canary-verify is the
actual gate (it runs against the canary first and aborts the rollout
if the canary fails to come up).
Gate the floor on TOTAL_VERIFIED >= 4. Truth table:
TOTAL UNREACHABLE RESULT
1 1 soft-warn (original e2e flake case)
4 2 soft-warn (exactly half)
4 3 hard-fail (75% — real outage)
10 6 hard-fail (60% — real outage)
Mirrored across staging.yml + main.yml.

Belt-and-suspenders sanity floor on top of the unreachable-soft-warn
introduced earlier in this PR. Addresses the residual gap noted in
review: if a new image crashes on startup, every tenant ends up
unreachable, and the soft-warn alone would let that ship as a green
deploy. Canary-verify catches it on the canary tenant first, but this
guard is a fallback for canary-skip dispatches and same-batch races.
Threshold is 50% of healthz_ok-snapshotted tenants — comfortably above
the typical e2e-* teardown rate (5-10/hour, ~1 ephemeral tenant per
batch) but below any plausible real-outage scenario.
Mirrored across staging.yml + main.yml for shape parity.

Three findings from re-reviewing PR #2401 with fresh eyes:
1. Critical — port binding to 0.0.0.0
compose.yml's cf-proxy bound 8080:8080 (default 0.0.0.0). The harness
uses a hardcoded ADMIN_TOKEN so anyone on the local network or VPN
could hit /workspaces with admin privileges. Switch to 127.0.0.1:8080
so admin access is loopback-only — safe for E2E and prevents the
known-token leak.
2. Required — dead code in cp-stub
peersFailureMode + __stub/mode + __stub/peers were declared with
atomic.Value setters but no handler ever READ from them. CP doesn't
host /registry/peers (the tenant does), so the toggles couldn't
drive responses. Removed the dead vars + handlers; kept
redeployFleetCalls counter and __stub/state since those have a real
consumer in the buildinfo replay.
3. Required — replay's auth-context dependency
peer-discovery-404.sh's Python eval ran a2a_client.get_peers_with_
diagnostic() against the live tenant. Without a workspace token
file, auth_headers() yields empty headers — so the helper might
exercise a 401 branch instead of the 404 branch the replay claims
to test.
Split the assertion into (a) WIRE — direct curl proves the platform
returns 404 from /registry/<unregistered>/peers — and (b) PARSE —
feed the helper a mocked 404 via httpx patches, no network/auth.
Each branch tests exactly what it claims.
Also added a graceful skip when the workspace runtime in the
current checkout pre-dates #2399 (no get_peers_with_diagnostic
yet) — replay falls back to wire-only verification with a clear
message instead of an opaque AttributeError. After #2399 lands on
staging, both branches will run.
cp-stub still builds clean. compose.yml validates. Replay's bash
syntax + Python eval both verified locally.

The /buildinfo verify step (PR #2398) was treating "no /buildinfo response"
the same as "tenant returned wrong SHA" — both bumped MISMATCH_COUNT and
hard-failed the workflow. First post-merge run on staging caught a real
edge case: ephemeral E2E tenants (slug e2e-20260430-...) get torn down by
the E2E teardown trap between CP's healthz_ok snapshot and the verify step
running, so the verify step would dial into DNS that no longer resolves
and hard-fail on a benign condition.
The bug class we actually care about is STALE (tenant up + serving old
code, the #2395 root). UNREACHABLE post-redeploy is almost always a benign
teardown race; real "tenant up but unreachable" is caught by CP's own
healthz monitor + the alert pipeline, so double-counting it here was
making this workflow flaky on every staging push that overlapped E2E.
Wire:
- Split MISMATCH_COUNT into STALE_COUNT + UNREACHABLE_COUNT.
- STALE → hard-fail the workflow (the bug class we're guarding).
- UNREACHABLE → :⚠️:, don't fail. Reachable-mismatch still hard-fails.
- Job summary surfaces both lists separately so on-call can tell at a
glance which class fired.
Mirror in redeploy-tenants-on-main.yml for shape parity (prod has fewer
ephemeral tenants but identical asymmetry would be a gratuitous fork).

The harness brings up the SaaS tenant topology on localhost using the
SAME workspace-server/Dockerfile.tenant image that ships to production.
Tests run against http://harness-tenant.localhost:8080 and exercise the
same code path a real tenant takes:
client
→ cf-proxy (nginx; CF tunnel + LB header rewrites)
→ tenant (Dockerfile.tenant — combined platform + canvas)
→ cp-stub (minimal Go CP stand-in for /cp/* paths)
→ postgres + redis
Why this exists: bugs that survive `go run ./cmd/server` and ship to
prod almost always live in env-gated middleware (TenantGuard, /cp/*
proxy, canvas proxy), header rewrites, or the strict-auth / live-token
mode. The harness activates ALL of them locally so #2395 + #2397-class
bugs can be reproduced before deploy.
Phase 1 surface:
- cp-stub/main.go: minimal CP stand-in. /cp/auth/me, redeploy-fleet,
/__stub/{peers,mode,state} for replay scripts. Catch-all returns
501 with a clear message when a new CP route appears.
- cf-proxy/nginx.conf: rewrites Host to <slug>.localhost, injects
X-Forwarded-*, disables buffering to mirror CF tunnel streaming
semantics.
- compose.yml: one service per topology layer; tenant builds from
the actual production Dockerfile.tenant.
- up.sh / down.sh / seed.sh: lifecycle scripts.
- replays/peer-discovery-404.sh: reproduces #2397 + asserts the
diagnostic helper from PR #2399 surfaces "404" + "registered".
- replays/buildinfo-stale-image.sh: reproduces #2395 + asserts
/buildinfo wire shape + GIT_SHA injection from PR #2398.
- README.md: topology, quickstart, what the harness does NOT cover.
Phases 2-3 (separate PRs):
- Phase 2: convert tests/e2e/test_api.sh to target the harness URL
instead of localhost; make harness-based replays a required CI gate.
- Phase 3: config-coherence lint that diffs harness env list against
production CP's env list, fails CI on drift.
Verification:
- cp-stub builds (go build ./...).
- cp-stub responds to all stubbed endpoints (smoke-tested locally).
- compose.yml passes `docker compose config --quiet`.
- All shell scripts pass `bash -n` syntax check.

Closes#2397. Today, every empty-peer condition (true empty, 401/403, 404,
5xx, network) collapses to a single message: "No peers available (this
workspace may be isolated)". The user has no way to tell whether they need
to provision more workspaces (true isolation), restart the workspace
(auth), re-register (404), page on-call (5xx), or check network (timeout) —
five different operator actions, one ambiguous string.
Wire:
- new helper get_peers_with_diagnostic() in a2a_client.py returns
(peers, error_summary). error_summary is None on 200; a short
actionable string on every other branch.
- get_peers() now shims through it so non-tool callers (system-prompt
formatters) keep the bare-list contract.
- tool_list_peers() switches to the diagnostic helper and surfaces the
actual reason. The "may be isolated" string is removed; true empty
now reads "no peers in the platform registry."
Tests:
- TestGetPeersWithDiagnostic: 200, 200-empty, 401, 403, 404, 5xx,
network exception, 200-but-non-list-body, and the bare-list-shim
regression guard.
- TestToolListPeers: each diagnostic branch surfaces its reason +
explicit assertion that "may be isolated" is gone.
Coverage 91.53% (floor 86%). 122 a2a tests pass.

Closes the gap that let issue #2395 ship: redeploy-fleet workflows reported
ssm_status=Success based on SSM RPC return code alone, while EC2 tenants
silently kept serving the previous :latest digest because docker compose up
without an explicit pull is a no-op when the local tag already exists.
Wire:
- new buildinfo package exposes GitSHA, set at link time via -ldflags from
the GIT_SHA build-arg (default "dev" so test runs without ldflags fail
closed against an unset deploy)
- router exposes GET /buildinfo returning {git_sha} — public, no auth,
cheap enough to curl from CI for every tenant
- both Dockerfiles thread GIT_SHA into the Go build
- publish-workspace-server-image.yml passes GIT_SHA=github.sha for both
images
- redeploy-tenants-on-main.yml + redeploy-tenants-on-staging.yml curl each
tenant's /buildinfo after the redeploy SSM RPC and fail the workflow on
digest mismatch; staging treats both :latest and :staging-latest as
moving tags; verification is skipped only when an operator pinned a
specific tag via workflow_dispatch
Tests:
- TestGitSHA_DefaultDevSentinel pins the dev default
- TestBuildInfoEndpoint_ReturnsGitSHA pins the wire shape that the
workflow's jq lookup depends on

Two related fixes after self-review of #2396:
1. workspace_bootstrap.go:62 — `SET status = 'failed'` was missed in the
initial sweep. Now parameterized as $3 with models.StatusFailed.
Test fixed with the additional WithArgs sentinel.
2. Drift gate now scans production .go AST for hard-coded
`UPDATE workspaces … SET status = '<literal>'` and fails with
file:line. This catches the kind of miss the first commit just
fixed — the original migration-vs-codebase axis only verified
AllWorkspaceStatuses ⊆ enum, not "no raw literals in writes."
Verified the gate fires: dropped a synthetic 'failed' literal into
internal/handlers/_drift_sanity.go and confirmed the gate flagged
"internal/handlers/_drift_sanity.go:6 → SET status = 'failed'".

Eliminate raw 'awaiting_agent'/'hibernating'/'failed'/etc string literals
from production status writes. Adds models.WorkspaceStatus typed alias and
models.AllWorkspaceStatuses canonical slice; every UPDATE workspaces SET
status = ... now passes a parameterized $N typed value rather than a
hard-coded SQL literal.
Defense-in-depth follow-up to migration 046 (#2388): the Postgres enum
type was missing 'awaiting_agent' + 'hibernating' for ~5 days because
sqlmock regex matching cannot enforce live enum constraints. The drift
gate is now a proper Go AST + SQL parser (no regex), asserting the
codebase ⊆ migration enum and every const appears in the canonical
slice. With status as a parameterized typed value, future enum mismatches
fail at the SQL layer in tests, not silently in prod.
Test coverage: full suite passes with -race; drift gate green.

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.

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.

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.
