// Regression tests for ConfigTab Provider override (Option B PR-5).
//
// What this pins: a free-text Provider combobox in the Runtime section
// that lets the operator override the model→provider derivation hermes-
// agent does internally. Without this UI, a fresh signup whose Hermes
// workspace defaults to a model with no clean vendor prefix (e.g.
// `nousresearch/hermes-4-70b`) hits the runtime's own preflight error:
// "No LLM provider configured. Run `hermes model` to select a
// provider, or run `hermes setup` for first-time configuration."
// — even though tasks #195-198 wired the entire downstream pipe so a
// non-empty provider WOULD flow through canvas → workspace-server →
// CP user-data → workspace config.yaml → hermes adapter.
//
// Hongming Wang hit this on hongming.moleculesai.app at signup
// 2026-05-01T17:35Z. Backend PRs were green, the gap was the missing
// UI to set the value.
//
// Each test pins one invariant. If any fails, the bug is back.

be treated as a publish artifact only. It can be archived or used as a
read-only mirror.
## Where to make changes
**All runtime edits land in `molecule-monorepo/workspace/`. Period.**
The GitHub repo `Molecule-AI/molecule-ai-workspace-runtime` is **mirror-only**.
It exists so external consumers (template repos, downstream operators) have a
git-cloneable artifact that mirrors the PyPI wheel — nothing more.
- **Direct PRs against `molecule-ai-workspace-runtime` are auto-rejected by
the `mirror-guard` CI check.** The check fails any push that did not come
from the publish pipeline. There is no opt-out — file the change against
`molecule-monorepo/workspace/` instead.
- **The mirror + the PyPI wheel both auto-regenerate on every push to
`staging`** via `.github/workflows/publish-runtime.yml` (which calls
`scripts/build_runtime_package.py`, builds wheel + sdist, smoke-imports,
uploads to PyPI via Trusted Publisher, and force-pushes the rewritten tree
to the mirror repo). You never touch the mirror by hand.
If you have an old local clone of the mirror and try to push a fix to it
directly, expect a CI failure with a message pointing you here. Re-open the
change against `molecule-monorepo/workspace/` and let the publish workflow
do the rest.

# Demo-day runbook
Pre-, during-, and post-demo operational procedures for the molecule
production stack. Updated 2026-05-01 ahead of the funding-demo on
~2026-05-06.
The whole stack:
```
Vercel canvas (app.moleculesai.app)
→ Railway controlplane (api.moleculesai.app)
→ CloudFront/Cloudflare per-tenant edge (<slug>.moleculesai.app)
→ EC2 tenant instance running platform container
→ Docker workspaces pulled from
ghcr.io/molecule-ai/workspace-template-<runtime>:latest
```
Every layer has its own deploy/rollback story. This runbook indexes
them in the order an operator would touch them during an incident.
## Pre-demo (T-48h to T-1h)
### 1. Freeze the runtime + template image cascade
A merge to `molecule-core/staging` that touches `workspace/**` triggers
`publish-runtime.yml` → PyPI bump → repository_dispatch → 8 template
repos rebuild and re-tag `:latest`. A merge to any template repo's
`main` triggers the same final re-tag directly. Either path means a
new workspace provision during the demo pulls whatever `:latest`
resolved to seconds earlier.
Capture current good digests + disable both cascade vectors:
```bash
# Dry-run first — verifies digests can be fetched and tooling is set up
scripts/demo-freeze.sh
# Apply
scripts/demo-freeze.sh --execute
```
The script writes two receipts to `scripts/demo-freeze-snapshots/`:
- `digests-<TS>.txt` — current `:latest` digest per template (rollback target if needed)
- `disabled-workflows-<TS>.txt` — workflow paths to re-enable post-demo
Verify the freeze landed:
```bash
gh workflow list -R Molecule-AI/molecule-core | grep publish-runtime
# expect: status = disabled_manually
```
If a critical fix MUST ship during the freeze window:
1. `gh workflow enable publish-runtime.yml -R Molecule-AI/molecule-core`
2. Merge the fix
3. Watch the cascade through to GHCR:latest manually
4. Smoke-verify against a staging tenant (`scripts/api-smoke.sh` or
manual canvas walkthrough)
5. `gh workflow disable publish-runtime.yml -R Molecule-AI/molecule-core` to re-freeze
Don't auto-promote during the freeze — the value of the freeze is that
nothing happens automatically.
### 2. Confirm production CP is on the expected SHA
```bash
gh run list -R Molecule-AI/molecule-controlplane --branch main --limit 5
# Last `ci` run should be SUCCESS with the SHA you intend to demo on
```
Railway auto-deploys from main. Spot-check `api.moleculesai.app`:
```bash
curl -fsS -H "Authorization: Bearer $CP_ADMIN_API_TOKEN" \
https://api.moleculesai.app/cp/admin/orgs?limit=1
# Expect: 200 + a JSON {"orgs": [...]}
```
### 3. Confirm production canvas (Vercel) is on main
Vercel auto-deploys `main`. Verify in the Vercel dashboard the most
recent prod deploy ran from the expected commit SHA.
### 4. Pre-warm the demo tenant
Cold-start times on workspace-template images:
| Runtime | Cold-start (first boot) |
|---|---|
| claude-code | ~30-60s |
| openclaw | ~1-2 min |
| langgraph | ~1 min |
| hermes | **~7 min** (large image) |
If the demo will use `hermes`, provision the demo workspace at least
10 min before. The cold-start clock starts when the workspace is
created, not when it's used.
## During demo — emergency rollback levers
### Lever A: Platform-image rollback (canvas/CP layer regression)
If the canvas or platform container shipped a regression, retag
`:latest` to a prior staging SHA without rebuilding:
```bash
# Find a known-good SHA from staging history
gh run list -R Molecule-AI/molecule-core --workflow=publish-canvas-image.yml --limit 5
# Roll both platform + tenant images
GITHUB_TOKEN=$(gh auth token) scripts/rollback-latest.sh <good-sha>
```
`rollback-latest.sh` retags both `ghcr.io/molecule-ai/platform:latest`
and `ghcr.io/molecule-ai/platform-tenant:latest`. Existing tenants
auto-pull `:latest` every 5 min — rollback propagates without manual
restart.
### Lever B: Workspace-template image rollback
If a specific runtime template (claude-code, hermes, etc.) shipped a
broken `:latest`:
```bash
# Get the demo's snapshotted-good digest from the freeze receipt
grep claude-code scripts/demo-freeze-snapshots/digests-<TS>.txt
# Retag :latest back to the snapshotted digest using crane
crane auth login ghcr.io -u "$(gh api user --jq .login)" \
--password-stdin <<< "$(gh auth token)"
crane tag \
ghcr.io/molecule-ai/workspace-template-claude-code@sha256:<digest> \
latest
```
The next workspace provision pulls the rolled-back image. Existing
workspaces are unaffected (their image is already loaded into Docker).
### Lever C: Wedged demo tenant — redeploy
If the demo tenant's EC2 instance is wedged (boot succeeded but app
not responding, or a stuck workspace), the controlplane has an admin
redeploy endpoint:
```bash
# AWS-side: forces a fresh EC2 launch with current image. ~3 min.
curl -fsS -X POST \
-H "Authorization: Bearer $CP_ADMIN_API_TOKEN" \
https://api.moleculesai.app/cp/admin/orgs/<slug>/redeploy
```
WARNING per memory: this triggers real EC2 + SSM actions on production.
Double-check `<slug>` against the demo tenant's slug before pressing
return. The `/redeploy` endpoint is idempotent on the EC2 side but
WILL drop active SSH sessions.
### Lever D: Specific bad workspace — delete
If a single workspace inside the demo tenant is misbehaving (e.g.
hermes wedged on cold-start, claude-code returning the generic
"Agent error (Exception)" message), kill it:
```bash
# Get the demo tenant's per-tenant ADMIN_TOKEN
TENANT_ADMIN=$(curl -fsS -H "Authorization: Bearer $CP_ADMIN_API_TOKEN" \
https://api.moleculesai.app/cp/admin/orgs/<slug>/admin-token \
| jq -r .admin_token)
ORG_ID=$(curl -fsS -H "Authorization: Bearer $CP_ADMIN_API_TOKEN" \
https://api.moleculesai.app/cp/admin/orgs?limit=20 \
| jq -r '.orgs[] | select(.slug=="<slug>") | .id')
# Delete the bad workspace
curl -fsS -X DELETE \
-H "Origin: https://<slug>.moleculesai.app" \
-H "Authorization: Bearer $TENANT_ADMIN" \
-H "X-Molecule-Org-Id: $ORG_ID" \
https://<slug>.moleculesai.app/workspaces/<workspace-id>
```
Then re-provision a fresh workspace from the canvas. Faster than
debugging the wedged one.
### Lever E: Railway production rollback (CP regression)
If the last Railway deploy of CP introduced a regression that lever A
can't fix (e.g. a logic bug, not a container issue):
1. Open Railway dashboard → molecule-platform → controlplane → Deployments
2. Find the previous-known-good deployment
3. Click **Rollback to this deployment**
Manual step — no CLI equivalent built. Takes ~30s to redeploy from
the prior image. Note: rollback restores the prior code AND prior env
var snapshot; don't expect any env var changes made since to persist.
### Lever F: Vercel production rollback (canvas regression)
If the canvas ships a regression:
1. Open Vercel dashboard → molecule-app → Deployments
2. Find the previous prod deployment
3. **Promote to Production**
Same pattern as Railway — fast revert, no rebuild.
## Tenant-level read-only diagnostics (not actions)
Useful during a "is this working?" moment without touching anything:
```bash
# Tenant infra state
curl -fsS -H "Authorization: Bearer $CP_ADMIN_API_TOKEN" \
"https://api.moleculesai.app/cp/admin/orgs?limit=20" \
| jq '.orgs[] | select(.slug=="<slug>")'
# Tenant boot events (debug a stuck provision)
curl -fsS -H "Authorization: Bearer $CP_ADMIN_API_TOKEN" \
"https://api.moleculesai.app/cp/admin/tenants/<slug>/boot-events?limit=50" \
| jq
# Workspace activity (debug an unresponsive agent)
curl -fsS \
-H "Origin: https://<slug>.moleculesai.app" \
-H "Authorization: Bearer $TENANT_ADMIN" \
-H "X-Molecule-Org-Id: $ORG_ID" \
"https://<slug>.moleculesai.app/workspaces/<workspace-id>/activity?limit=20" \
| jq
```
## Post-demo (T+30m to T+24h)
### 1. Thaw the cascades
```bash
# Find the freeze receipt
ls scripts/demo-freeze-snapshots/
# Thaw — pass the timestamp suffix
scripts/demo-thaw.sh 20260506-180000
```
The next merge to `molecule-core/staging` (workspace/**) or any
template repo's `main` will resume the auto-rebuild cascade.
### 2. Audit what was held back
If any merges queued during the freeze:
```bash
gh pr list -R Molecule-AI/molecule-core --base staging --state merged \
--search "merged:>=$(date -u -v-7d +%Y-%m-%d)"
```
Verify each merge's CI is green and dispatch the runtime cascade once
to ensure all templates rebuild against the post-freeze HEAD.
### 3. File a post-mortem if anything fired
If any rollback lever was used during the demo, file a brief doc:
- Which lever (A through F)
- Which SHA was rolled back FROM and TO
- Did the rollback fully resolve the issue or was a follow-up needed
- Whether the underlying regression should have been caught by CI
## Common issues + first-line fix
| Symptom | First lever to try |
|---|---|
| Workspace boots but agent always errors | Lever D (delete + reprovision) |
| Whole tenant unreachable | Lever C (redeploy) |
| Canvas crashes on load | Lever F (Vercel rollback) |
| Login broken / API errors | Lever E (Railway rollback) |
| Specific runtime broken across tenants | Lever B (template image rollback) |
| Platform container regression | Lever A (rollback-latest.sh) |
| Mid-demo stray PR auto-published a bad image | Lever B + investigate why freeze didn't catch it |
## Auth fingerprint (rotate post-demo)
The freeze + rollback procedures assume:
- `CP_ADMIN_API_TOKEN` available via `railway variables --kv --environment production`
- `gh auth token` returns a working PAT with `workflow:write` + `write:packages`
- `crane` installed (`brew install crane`)
After the demo, **rotate** `CP_ADMIN_API_TOKEN` (it's the keys-to-the-kingdom
token for production) — it likely got copy-pasted into shells during
the demo.
```bash
# Generate a new admin token
NEW_TOKEN=$(openssl rand -hex 32)
# Update Railway production env var (and optionally staging)
railway variables --set CP_ADMIN_API_TOKEN="$NEW_TOKEN" --environment production
# Restart CP service to pick up the change
# (Railway auto-restarts on env var change)
# Verify
curl -fsS -H "Authorization: Bearer $NEW_TOKEN" \
https://api.moleculesai.app/cp/admin/orgs?limit=1
```

"""Tests for scripts/build_runtime_package.py — the wheel-build import rewriter.
Run locally: ``python3 -m unittest scripts/test_build_runtime_package.py -v``
Why this exists: PR #2433 shipped ``import inbox as _inbox_module`` inside
the workspace runtime, and the rewriter expanded it to
``import molecule_runtime.inbox as inbox as _inbox_module`` — invalid
Python. The wheel-smoke gate caught it post-merge but couldn't block
the merge (not a required check yet — see PR #2439). PR #2436 added a
build-time gate that raises ``ValueError`` on this pattern; this file
locks the rewriter's documented contract under unit test so the gate
itself can't silently regress.
Coverage:
- ``import X`` → ``import molecule_runtime.X as X``
- ``import X.sub`` → ``import molecule_runtime.X.sub``
- ``import X`` + trailing comment is preserved
- ``from X import Y`` → ``from molecule_runtime.X import Y``
- ``from X.sub import Y`` → ``from molecule_runtime.X.sub import Y``
- ``from X import Y, Z`` → ``from molecule_runtime.X import Y, Z``
- ``import X as Y`` → raises ValueError (the rewriter would
produce ``import molecule_runtime.X as X as Y``, syntax error)
- non-allowlist module names → not rewritten (regex anchors on the closed set)
- Indented imports (inside def/class) keep their indentation.

# Production-shape local harness
The harness brings up the SaaS tenant topology on localhost using the
same `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 — including TenantGuard middleware,
the `/cp/*` reverse proxy, the canvas reverse proxy, and a
Cloudflare-tunnel-shape header rewrite layer.
same `Dockerfile.tenant` image that ships to production. Tests target
the cf-proxy on `http://localhost:8080` and pass the tenant identity
via a `Host:` header — exactly the way production CF tunnel routes by
Host header. The cf-proxy nginx then rewrites headers and proxies to
the right tenant container, exercising the SAME code path a real tenant
takes including TenantGuard middleware, the `/cp/*` reverse proxy, the
canvas reverse proxy, and a Cloudflare-tunnel-shape header rewrite
layer.
Since Phase 2 the harness runs **two tenants in parallel** (alpha and
beta) with their own Postgres instance and distinct
`MOLECULE_ORG_ID`s — same shape as production, where each tenant gets
its own EC2 + DB. This is what cross-tenant isolation replays need to
prove TenantGuard actually 404s a misrouted request.
`tests/harness/_curl.sh` is the helper sourced by every replay. Per
tenant: `curl_alpha_anon` / `curl_alpha_admin` / `curl_beta_anon` /
`curl_beta_admin` / `psql_exec_alpha` / `psql_exec_beta`. Plus
deliberately-wrong cross-tenant negative-test helpers for isolation
replays: `curl_alpha_creds_at_beta` / `curl_beta_creds_at_alpha`.
Legacy single-tenant aliases (`curl_anon`, `curl_admin`, `psql_exec`)
default to alpha so pre-Phase-2 replays continue to work. New replays
should source `_curl.sh` rather than rolling their own curl.

Each tenant runs the production `Dockerfile.tenant` image with its own
admin token, org id, and Postgres instance — identical isolation
boundaries to production where each tenant gets a dedicated EC2 + DB.
cp-stub and redis are shared because they model the per-region
multi-tenant CP and a single Redis cluster.
## Quickstart

cd tests/harness
./up.sh # builds + starts all services
./seed.sh # mints admin token, registers two sample workspaces
./replays/peer-discovery-404.sh
./replays/buildinfo-stale-image.sh
./up.sh # builds + starts all services (both tenants)
./seed.sh # registers parent+child workspaces in BOTH tenants

First-time setup needs an `/etc/hosts` entry so `harness-tenant.localhost`
resolves to the local cf-proxy:
No `/etc/hosts` edit required — replays use the cf-proxy's loopback
port and pass the per-tenant `Host:` header (`_curl.sh` handles this
automatically). This matches how production CF tunnel routes: the URL
is the public CF endpoint, the Host header carries the per-tenant
identity. Quick check:
```bash
echo "127.0.0.1 harness-tenant.localhost" | sudo tee -a /etc/hosts
curl -H "Host: harness-tenant-alpha.localhost" http://localhost:8080/health
curl -H "Host: harness-tenant-beta.localhost" http://localhost:8080/health
```
(macOS resolves `*.localhost` automatically in some setups; Linux
typically does not.)
(If you have a legacy `/etc/hosts` entry from older docs, it still
works — `BASE`, `ALPHA_HOST`, `BETA_HOST` all honor env-var overrides.
The legacy `harness-tenant.localhost` host alias maps to alpha.)

## Roadmap
- **Phase 1 (shipped):** harness + cp-stub + cf-proxy + 2 replays + `run-all-replays.sh` runner.
- **Phase 2:** convert `tests/e2e/test_api.sh` to run against the
harness instead of localhost. Make harness-based E2E a required CI
check (a workflow that invokes `run-all-replays.sh` on every PR).
- **Phase 3:** config-coherence lint that diffs harness env list
against production CP's env list, fails CI on drift.
- **Phase 1 (shipped):** harness + cp-stub + cf-proxy + 4 replays + `run-all-replays.sh` runner. No-sudo `Host`-header path via `_curl.sh`. Per-replay psql seeding for tests that need DB-side fixtures.
- **Phase 2 (shipped):** multi-tenant — `tenant-alpha` + `tenant-beta` with their own Postgres instances and distinct `MOLECULE_ORG_ID`s; cf-proxy nginx routes by Host header (prod CF tunnel parity); `seed.sh` registers parent+child workspaces in both tenants; `_curl.sh` exposes per-tenant + cross-tenant-negative helpers; new replays cover TenantGuard isolation (`tenant-isolation.sh`) and per-tenant independence under concurrent load (`per-tenant-independence.sh`). `harness-replays.yml` runs `run-all-replays.sh` as a required check on every PR touching `workspace-server/**`, `canvas/**`, `tests/harness/**`, or the workflow itself.
- **Phase 3:** replace `cp-stub/` with the real `molecule-controlplane` Docker build. Add a config-coherence lint that diffs harness env list against production CP's env list and fails CI on drift. Convert `tests/e2e/test_api.sh` to target the harness instead of localhost.
- **Phase 4 (long-term):** Miniflare in front of cf-proxy for real CF emulation (WAF, BotID, rate-limit, cf-tunnel headers). LocalStack for the EC2 provisioner. Anonymized prod-traffic recording/replay for SaaS-scale regression detection.

# Production-shape harness for local E2E.
# Production-shape harness for local E2E. Multi-tenant.
#
# Reproduces the SaaS tenant topology on localhost using the SAME
# images that ship to production:
#
# client → cf-proxy (nginx, mimics CF tunnel headers)
# → tenant (workspace-server/Dockerfile.tenant — combined platform + canvas)
# → cp-stub (control-plane stand-in) for /cp/* and CP-callback paths
# → postgres + redis (same versions as production)
# client → cf-proxy (nginx, mimics CF tunnel headers, routes by Host)
# ├─ Host: harness-tenant-alpha.localhost → tenant-alpha
# │ ↓ (CP_UPSTREAM_URL=http://cp-stub:9090)
# │ tenant-alpha (workspace-server/Dockerfile.tenant)
# │ ↓
# │ postgres-alpha (per-tenant DB, matches prod)
# ├─ Host: harness-tenant-beta.localhost → tenant-beta
# │ ↓
# │ tenant-beta + postgres-beta
# └─ cp-stub + redis (shared infra; CP is Railway-singleton in prod,
# redis is shared cluster)
#
# Why this matters: the workspace-server binary IS identical between
# local and production. The bugs that survive local E2E are topology
# bugs — env-gated middleware (TenantGuard, CP proxy, Canvas proxy),
# auth state, header rewrites, real production image. This harness
# activates ALL of them.
# The two-tenant topology catches:
# - TenantGuard cross-tenant escape (alpha-org token shouldn't see
# beta-tenant data even with a valid bearer)
# - cf-proxy Host-header routing correctness
# - Per-tenant DB isolation (workspaces table, activity_logs)
# - Concurrent multi-tenant operation (no shared mutable state)
#

# Replay for the channel envelope peer_id trust-boundary fix
# (PR #2481, follow-up to PR #2471). Verifies that the PUBLISHED wheel
# installed on this machine — not local source — gates malformed peer_id
# at both the envelope builder and the agent_card_url builder.
#
# Why this matters:
# - Unit tests in workspace/tests/ run against local source. They
# prove the fix works in source. They DO NOT prove the published
# wheel contains the fix.
# - The wheel rewriter (scripts/build_runtime_package.py) renames
# symbols + paths. Any rewrite drift could silently strip the
# guard from the shipped artifact.
# - This replay imports from `molecule_runtime.a2a_mcp_server` (the
# wheel-rewritten path), exercises the actual published code, and
# asserts the envelope shape. If the wheel build ever ships without
# the guard, this fails — even if unit tests on local source pass.
#
# Phases:
# A. Confirm an installed molecule-runtime version that contains the
# #2481 fix (>= 0.1.78).
# B. Call `_build_channel_notification` with peer_id="../../foo" and
# assert (1) meta["peer_id"] == "", (2) no agent_card_url field,
# (3) no peer_name/peer_role.
# C. Symmetric case: peer_id with embedded XML-attribute injection
# bytes — assert the same scrubbing.
# D. Happy path: a valid UUID peer_id is preserved (proves we didn't
# regress legitimate enrichment).
# E. Direct check on the URL builder — `_agent_card_url_for("../../foo")`
# must return "" and never an unsanitised URL.

# What this catches that unit tests don't:

# - JSON encoding of created_at across the wire (timezone, precision).
#
# Phases:
# A. Seed three a2a_receive rows for alpha with peer_id=beta, spread
# across distinct timestamps.
# B. Basic peer_id filter: GET ?type=a2a_receive&peer_id=beta&limit=10
# → assert 3 rows DESC.
# C. Limit cap: limit=2 → assert 2 newest rows.
# D. before_ts paging: take the 2nd-newest's created_at, GET with

# E. OR clause (target side): seed an a2a_send row where source=alpha,

# Replay for per-tenant independence — each tenant runs the same
# workflow concurrently with no cross-bleed in workspaces table or
# activity_logs.
#
# What this proves that tenant-isolation.sh doesn't:
# tenant-isolation.sh proves that REQUESTS get rejected at the
# middleware layer when they target the wrong tenant. THIS replay
# proves that even when both tenants are doing legitimate work
# simultaneously, the back-end state stays partitioned: no row in
# alpha's activity_logs ever shows up in beta's, no FK-resolution
# ever crosses tenants, etc.
#
# Test shape: seed activity_logs in BOTH tenants in parallel using
# distinct row counts (3 vs 5) so we can distinguish them. Then
# fetch each tenant's history and assert the count + content match
# the seed exactly — proves no leak in either direction.
#
# Phases:
# A. Seed alpha tenant: 3 a2a_receive rows (parent ← child).
# B. Seed beta tenant: 5 a2a_receive rows (parent ← child).
# C. GET alpha history → exactly 3 rows, all alpha-summary.
# D. GET beta history → exactly 5 rows, all beta-summary.
# E. Direct DB sanity — alpha PG has only alpha rows, beta PG only beta.
# F. Concurrent write race — both tenants take turns INSERTing
# simultaneously; each tenant's count after the race matches what
# it INSERTed. Catches "shared cache poison" / "shared connection
# pool" failure modes that don't show up in single-tenant tests.

#!/usr/bin/env bash
# Replay for cross-tenant isolation — TenantGuard middleware MUST 404
# any request whose X-Molecule-Org-Id (or Fly-Replay state, or
# same-origin Canvas trust) doesn't match the tenant container's
# configured MOLECULE_ORG_ID.
#
# Why this matters in production:
# - One Cloudflare tunnel front-doors every tenant subdomain.
# - DNS/routing layer can mis-direct a request (CF cache poisoning,
# misconfigured CNAME, internal traffic mirror).
# - TenantGuard is the last-line defense — it 404s any request whose
# declared org doesn't match what the tenant binary was provisioned
# with. Returning 404 (not 403) is intentional: the existence of a
# tenant on this machine must not be probable by an outsider.
#
# What this replay catches:
# - A regression where TenantGuard accidentally allows requests with
# a different org id (e.g. someone removes the strict equality check).
# - cf-proxy routing-by-Host bug that sends alpha's request to beta's
# container (the negative test would suddenly succeed).
# - Allowlist drift — if /workspaces is added to tenantGuardAllowlist
# it would silently be cross-tenant readable.
#
# Phases:
# A. Positive controls — each tenant accepts its own valid creds.
# B. Org-header mismatch — alpha-org header at beta's URL → 404.
# C. Reverse — beta-org header at alpha's URL → 404.
# D. Right URL, wrong org header (typo) → 404.
# E. Bearer present but no org header → 404 (TenantGuard rejects).
# F. Per-tenant DB isolation — alpha's /workspaces enumerates only
# alpha workspaces; beta's only beta. Confirms cf-proxy + TenantGuard
# really did partition the request to the right backing DB.
# G. Allowlisted /health stays public on both tenants (sanity check —
# a regression that put /health behind the guard would 404 too).

// 1. Every provision goroutine produces ONE entry log line ("CPProvisioner:

// 2. Every goroutine reaches its registered exit path (cpProv.Start),

//
// If the silent-drop class is present in current head code, this test
// fails because either (a) the entry-log count is < 7 (meaning one or

"""MCP initialize handshake result.
Three fields together expose a dual-path inbound delivery contract
so push UX works on hosts that support it and polling falls in
cleanly everywhere else — universal by design, no per-client
branching:
1. ``capabilities.experimental.claude/channel`` — declares the
Claude Code channel capability. When the host is Claude Code
AND launched with ``--dangerously-load-development-channels``
(or this server name is on Claude Code's approved allowlist),
the MCP runtime registers a listener for our
``notifications/claude/channel`` emissions and routes them as
inline ``<channel>`` conversation interrupts. When the host is
any other MCP client (Cursor, Cline, opencode, hermes-agent,
codex) or Claude Code without the flag, this capability is
a no-op — the host simply ignores the notification method,
and the poll path below carries the load.
2. ``instructions`` — non-empty, describes BOTH delivery paths
(push tag and poll-on-every-turn via ``wait_for_message``)
converging on the same ``inbox_pop`` ack. The instructions
field is read by every spec-compliant MCP client and surfaced
to the agent's system prompt automatically, so the polling
contract reaches every host without any per-client wiring.
Required for the channel to be usable per
code.claude.com/docs/en/channels-reference.md.
3. ``protocolVersion`` — pinned to the version negotiated with
Claude Code at task #46 implementation; bumping it changes
what fields the host expects.
Mirrors the contract used by the official telegram channel plugin
(claude-plugins-official/telegram/server.ts:370-396) for the push
half. The poll half is universal MCP — no client-specific
extensions.
Why both paths instead of picking one:
- Push-only: silently regresses on every non-Claude-Code client
and on standard Claude Code launches without the dev-channels
flag (verified live 2026-05-01 — a canvas message landed in
the inbox but never reached the agent loop until manual
`inbox_peek`).
- Poll-only: works everywhere but stalls 0–N seconds per turn
even on hosts that could push. Push is strictly better when
available.
- Both: poll covers the floor universally; push promotes to
zero-stall delivery when the host opts in. Same `inbox_pop`
dedupes the race.

"""Resolve the configs directory used by the workspace runtime.
The runtime persists per-workspace state to a single directory:
``.auth_token`` (platform_auth), ``.platform_inbound_secret``
(platform_inbound_auth), ``.mcp_inbox_cursor`` (inbox). Inside a
workspace EC2 container that directory is ``/configs`` — a tmpfs/EBS
mount owned by the agent user, populated by the provisioner before
runtime boot.
Outside a container — operators running ``molecule-mcp`` on a laptop
for the external-runtime path — ``/configs`` doesn't exist (or, if it
does, isn't writable by an unprivileged user). The default would
silently fail on the first heartbeat: ``.platform_inbound_secret``
write hits ``Read-only file system: '/configs'``, the heartbeat thread
logs and dies, the workspace flips offline within a minute. The
operator sees no actionable error.
This module is the single resolution point. Resolution order:
1. ``CONFIGS_DIR`` env var, if set — explicit operator override.
2. ``/configs`` — used iff the path exists AND is writable. This
preserves the in-container default for every existing deployment.
3. ``$HOME/.molecule-workspace`` — the non-container fallback,
created with mode 0700 so per-file 0600 perms aren't undermined
by a world-readable parent.
Not cached: callers (heartbeat thread, MCP tools) hit this at most a
few times per second; reading the env var + one ``stat()`` call is
cheap, and the existing call sites read ``os.environ`` live so tests
that monkeypatch ``CONFIGS_DIR`` between cases keep working.

"""Boot smoke mode — exercises the executor's full import tree without touching real platforms.
Why this exists (issue #2275): the existing `wheel_smoke.py` only IMPORTS
`molecule_runtime.main` at module scope. Lazy imports buried inside
`async def execute(...)` bodies (e.g. `from a2a.types import FilePart`)
NEVER evaluate at static-import time — they crash at first message
delivery in production.
The 2026-04-2x v0→v1 a2a-sdk migration shipped 5 such regressions in
templates that all looked fine at module-load smoke. This module fills
the gap by actually invoking `executor.execute(stub_ctx, stub_queue)`
once with a short timeout. If the import-tree is healthy the call
proceeds far enough to hit a network boundary (LLM call, etc.) and
times out — that's a *pass*. If a lazy import is broken, the call
raises `ImportError` / `ModuleNotFoundError` from inside the executor
body — that's a *fail*.
Universal wedge gate (task #131): timeout-as-pass alone misses init
wedges where the SDK process spins for 60s+ on a malformed argv
(claude-agent-sdk PR #25 class). After every result path, the smoke
consults `runtime_wedge.is_wedged()` — adapters opt-in by calling
`runtime_wedge.mark_wedged(reason)` from their executor's wedge catch
arm, and the smoke upgrades the provisional PASS to FAIL when the
flag is set. Non-opt-in adapters keep working as before — the check
is additive.
Activated by setting `MOLECULE_SMOKE_MODE=1` in the env. Wired into
`main.py` after `executor = await adapter.create_executor(...)` so the
full adapter setup path runs first; the smoke just adds one more
exercise step before exit.
CI usage (intended for `molecule-ci/.github/workflows/publish-template-image.yml`):
docker run --rm \
-e WORKSPACE_ID=fake -e MOLECULE_SMOKE_MODE=1 \
-e MOLECULE_SMOKE_TIMEOUT_SECS=90 \
"$IMAGE" molecule-runtime
The 90s timeout is calibrated to claude-agent-sdk's 60s
`initialize()` handshake — adapters with shorter init can lower it.

### inbox_pop
Standalone-runtime ONLY. Call after you've replied to a message returned from wait_for_message or inbox_peek to drop it from the queue. Idempotent — popping a missing id reports removed=false without erroring.
### chat_history
Call this when a peer_agent push lands and you need context from prior turns with that workspace — e.g. "what task did this peer assign me last hour?" or "what did I tell them?". Both sides of the conversation appear in chronological order, so the agent reads the log top-down. Cheaper than re-deriving context from memory because the platform already audits every A2A turn into activity_logs. Pair with `agent_card_url` from the channel envelope when you also need the peer's capabilities.
Always use list_peers first to discover available workspace IDs. Access control is enforced — you can only reach siblings and parent/children. If a delegation returns a DELEGATION FAILED message, do NOT forward the raw error to the user. Instead: (1) try a different peer, (2) handle the task yourself, or (3) tell the user which peer is unavailable and provide your own best answer.
