+name: Canary — staging SaaS smoke (every 30 min)
+
+# Minimum viable health check: provisions one Hermes workspace on a fresh
+# staging org, sends one A2A message, verifies PONG, tears down. ~8 min
+# wall clock. Pages on failure by opening a GitHub issue; auto-closes the
+# issue on the next green run.
+#
+# The full-SaaS workflow (e2e-staging-saas.yml) covers the broader surface
+# but runs only on provisioning-critical pushes + nightly — this one
+# catches drift in the 30-min window between those runs (AMI health, CF
+# cert rotation, WorkOS session stability, etc.).
+#
+# Lean mode: E2E_MODE=canary skips the child workspace + HMA memory +
+# peers/activity checks. One parent workspace + one A2A turn is enough
+# to signal "SaaS stack end-to-end is alive."

+# A green run means:

+#   - The trap fired teardown
+#   - The leak-detection poll found zero orphan orgs

+# compromised until it's fixed).
+#

+# CrewAI Competitive Proof Points — Sales Counter-Narrative Brief
+
+**Source:** GH#1398 CrewAI Enterprise Strategy
+**Author:** Research Lead
+**Date:** 2026-04-21
+**Purpose:** Equip Sales with credible counter-narrative in enterprise conversations while case study clearance is pending
+**Classification:** Internal — Sales / Marketing use only
+
+---
+
+## The Gap
+
+CrewAI has **18 named enterprise logos** (IBM, PwC, NTT DATA, PepsiCo, RBC, DocuSign + 12 others).
+Molecule AI has **zero named enterprise case studies**.
+
+This is a real GTM credibility gap. Enterprise buyers ask "who else is using this?" and CrewAI has a ready answer. Molecule AI needs a credible counter — not fabricated case studies, but a clear articulation of **why** the enterprise buyers who *are* evaluating Molecule AI chose (or would choose) it over CrewAI.
+
+This brief gives Sales that narrative.
+
+---
+
+## What CrewAI Is Winning On
+
+**1. Enterprise brand recognition** — IBM, PwC, NTT DATA are recognizable enterprise logos that signal "safe to buy." This is a perception advantage, not a technical one.
+
+**2. Agent marketplace ecosystem** — CrewAI's agent marketplace gives buyers a catalog of pre-built agents to deploy. Low friction, fast time-to-value on day one.
+
+**3. Agent portability (proprietary)** — CrewAI's agent export-as-MCP-server is technically interesting, but it also creates vendor lock-in (agents only work in CrewAI's ecosystem). Buyers may not recognize this as a cost until they're deep in the platform.
+
+**4. Dedicated VPC deployment (AMP Factory)** — Enterprise procurement wants isolated, dedicated infrastructure. CrewAI offers this; it's a real enterprise requirement.
+
+---
+
+## Where CrewAI Is Vulnerable
+
+**1. Data residency is impossible** — CrewAI AMP runs on CrewAI's cloud (or dedicated VPC on their infrastructure). Enterprise buyers with GDPR, data sovereignty, or internal security requirements cannot put sensitive data on CrewAI's infrastructure without significant legal review.
+
+**2. No org-scoped governance** — CrewAI's agent marketplace and execution model are developer-tool oriented. Org-level API keys, audit logs, MCP plugin allowlists, and compliance reporting are not primary features.
+
+**3. Enterprise lock-in is real** — Proprietary agent repos, export-as-MCP-server (which only works within CrewAI), VPC-baked deployment — these are switching costs dressed up as features. Enterprise buyers who understand agent portability will see through this.
+
+---
+
+## Molecule AI's Three Open Differentiators
+
+### 1. Remote Runtime — Agent Compute Where Data Lives
+
+**The argument:** "CrewAI AMP runs on their infrastructure. Molecule AI Remote Workspaces lets your agents run on your AWS account, your on-prem server, or your data center. Your raw data never touches our platform."
+
+**When to use it:** Any enterprise buyer with data residency requirements, GDPR concerns, financial services regulation, or internal security policies that prohibit sending data to third-party AI infrastructure.
+
+**Proof point available:** The AWS data engineering team is already using this deployment model — raw data never touches Molecule AI.
+
+**Competitive response to "but CrewAI has dedicated VPC":** "AMP Dedicated VPC is still CrewAI's infrastructure. Remote Runtime on your own AWS account means your data never leaves your environment — not even their 'dedicated' cloud."
+
+---
+
+### 2. Org-Scoped API Keys + Audit Logs — Governance Without Sacrifice
+
+**The argument:** "Molecule AI was built for platform teams. Org-scoped API keys mean you can give each team autonomous agent access without giving them cross-org visibility. Audit logs give you a full trace of every agent action. MCP plugin allowlists let you control which tools are available to which agents."
+
+**When to use it:** VP Engineering, Director of Developer Productivity, Head of Platform Engineering — the people responsible for AI governance, not just AI adoption.
+
+**Key comparison:**
+
+| Feature | CrewAI | Molecule AI |
+|---------|--------|-------------|
+| Org-level API keys | No | Yes |
+| Audit logs | Basic | Full trace |
+| MCP plugin allowlists | No | Yes |
+| Workspace-level isolation | No | Yes |
+| Cross-team visibility controls | No | Yes |
+
+**Competitive response to "we can build governance ourselves":** "You can — but Molecule AI ships governance on day one. Building org-scoped auth and audit logging on top of CrewAI takes months. With Molecule AI it's already there."
+
+---
+
+### 3. Multi-Tenant SaaS + Docker Portability — Platform Day One
+
+**The argument:** "Molecule AI is a multi-tenant SaaS platform. You can be up and running in hours. But because we use the A2A protocol and Docker as the agent runtime, your agents are portable. If you want to move to self-hosted later, you can — your agents run in Docker containers, not in proprietary CrewAI primitives."
+
+**Key comparison:**
+
+| Feature | CrewAI | Molecule AI |
+|---------|--------|-------------|
+| Time to first agent | Hours | Hours |
+| Self-hosted option | AMP Dedicated VPC (their infra) | Remote Runtime (your infra) |
+| Agent portability | Proprietary export | Docker / A2A standard |
+| Mixed fleet (cloud + self-hosted) | No | Yes — same Canvas, same auth |
+| Platform team maintenance | High | Low (platform manages uptime) |
+
+**The lock-in reversal:** "CrewAI's agent marketplace is impressive — but those agents only run on CrewAI. Molecule AI's .bundle.json format and A2A protocol mean your agents can run anywhere the protocol is implemented. That's portability, not vendor lock-in."
+
+---
+
+## Counter-Narrative for Each CrewAI Win
+
+### When the buyer says: "CrewAI has IBM and PwC"
+
+**Say:** "Those are great enterprise logos — CrewAI has done a good job landing big names. Who did they replace, and does that match your situation? Enterprise logos don't always mean enterprise-ready for your specific use case. We'd love to understand your requirements and show you what Molecule AI's Remote Runtime and org governance look like for your team's profile."
+
+**Why this works:** You acknowledge the competitor's strength without contesting it. You redirect to the buyer's actual problem.
+
+---
+
+### When the buyer says: "CrewAI's agent marketplace gives us ready-to-deploy agents"
+
+**Say:** "The marketplace is a good fast-start — low friction on day one. But pre-built agents are a starting point, not a destination. The question is: what happens when you need to customize, extend, or move those agents? With Molecule AI, your agents are Docker containers running the A2A protocol — they're portable by design. With CrewAI's marketplace, you're building on their agent format."
+
+**Why this works:** You reframe the marketplace as a short-term convenience vs. long-term flexibility.
+
+---
+
+### When the buyer says: "CrewAI's dedicated VPC is good enough for our security requirements"
+
+**Say:** "AMP Dedicated VPC is dedicated — but it's still on CrewAI's infrastructure. Your data is logically isolated, not geographically isolated. If your security team requires that agent compute runs in your own AWS account — not just a 'dedicated' partition on CrewAI's cloud — Remote Runtime is the only option that actually delivers that. And you get the same Canvas, the same auth, the same A2A coordination."
+
+**Why this works:** You distinguish logical isolation from actual data residency control.
+
+---
+
+## The Narrative Frame for Enterprise Buyers
+
+> "CrewAI is winning on enterprise logos and a good developer experience. That's real — they're a strong competitor. Where Molecule AI is purpose-built for the enterprise platform team: agents that run where your data lives, governance that ships on day one, and portability that protects you from lock-in. If those are your priorities — and for platform teams, they usually are — let's look at what that looks like for your specific use case."
+
+---
+
+## Proof Points to Have Ready
+
+**Differentiator 1 (Remote Runtime):**
+> "A data engineering team is running Molecule AI agents on their own AWS account right now. Raw data never touches our platform. That's the deployment model, not a workaround."
+
+**Differentiator 2 (Org Governance):**
+> "Org-scoped API keys, audit logs, and MCP plugin allowlists are in the product today. Your platform team can control which teams have access to which tools, and audit every agent action — without building it yourselves."
+
+**Differentiator 3 (Portability):**
+> "Our agents run as Docker containers using the A2A protocol. That's not a proprietary format — it's a standard. If you want to move to self-hosted, your agents come with you."
+
+---
+
+## Status of Named Case Studies
+
+Molecule AI is actively pursuing enterprise reference customers. Named case studies are in clearance — Legal review expected to complete within 2–4 weeks. Anonymized references are available immediately upon request.
+
+**Sales action:** If a named reference would close a specific deal, flag to Marketing Lead — we can prioritize clearance for high-value opportunities.

+# Legal Reference Clearance Brief — Enterprise Case Study
+
+**Prepared by:** Research Lead / Marketing Lead
+**For:** Legal / Contracts Review
+**Date:** 2026-04-21
+**Reference:** GH#1405 — Ship 2–3 named enterprise case studies before Phase 30 GTM launch
+**Timeline:** Clearance requested — 2–4 week process; start immediately
+
+---
+
+## Purpose
+
+Molecule AI is preparing enterprise case studies for Phase 30 GTM launch. This brief requests Legal review to determine what reference information can be used publicly, with what attribution, and under what constraints.
+
+**This is a blocking dependency for GH#1405.** Legal clearance timelines (2–4 weeks) mean outreach must begin this week to close before Phase 30 GTM.
+
+---
+
+## Request to Legal
+
+Please advise on:
+
+1. What reference information can be used publicly?
+2. What attribution is approved (named company, anonymized role/industry, fully anonymous)?
+3. Does the customer need to provide written approval, or does our contract govern reference rights?
+4. Are there any industries or contract tiers where reference is prohibited or restricted?
+
+---
+
+## Reference Candidate A — Data Engineering Team (AWS)
+
+**This candidate is the preferred starting point** — the use case is already referenced (anonymously) in our sales materials, suggesting the customer may be open to expanded reference rights.
+
+### Customer Profile
+- **Anonymized name:** "A data engineering team at a US-based enterprise"
+- **Industry:** Data / analytics (exact vertical on file with CS)
+- **Contact role:** Data Engineering Lead (name on file with CS)
+
+### What Was Deployed
+
+| Component | Detail |
+|-----------|--------|
+| **Platform** | Molecule AI Remote Workspaces |
+| **Backend** | AWS (customer-managed EC2/ECS compute) |
+| **MCP stack** | MCP-compatible data tools (specific integrations on file) |
+| **Agent count** | [TBD — request from CS] |
+| **Auth model** | Org-scoped API keys |
+
+### Use Case Summary
+
+The team deployed autonomous pipeline agents that run on their own AWS account. Raw data never touches the Molecule AI platform — the platform handles orchestration and coordination; agent compute runs in the customer's AWS environment.
+
+**Deployment model:** Remote Runtime (self-hosted compute, platform-managed orchestration)
+
+### Outcome
+
+> "A data engineering team is currently using this for a pipeline agent running in their own AWS account — raw data never touches the Molecule AI platform."
+— Phase 30 Sales Enablement Materials
+
+*[CS to confirm: Is this quote attributable or directional? Can we publish this verbatim or paraphrase?]*
+
+### What We're Asking Legal to Approve
+
+**Minimum viable clearance (anonymous):**
+- Publish use case description (anonymized: "a data engineering team at a US enterprise")
+- Describe deployment model (Remote Runtime on AWS)
+- Reference outcome (data residency advantage)
+- **Do not** include company name, contact name, or specific metrics
+
+**Preferred clearance (named):**
+- Named company + contact name + title
+- Quote from contact (1–2 sentences)
+- Specific outcome metric if available
+
+**If named clearance fails:**
+- Approve anonymized version above
+- Proceed with publication; revisit named clearance in Q2
+
+---
+
+## Reference Candidate B — Enterprise Platform Team (Governance)
+
+*To be surfaced by CS from pipeline contacts — see enterprise-case-study-pipeline-targeting-brief.md*
+
+| Field | Value |
+|-------|-------|
+| **Company** | [TBD — CS to identify from pipeline] |
+| **Industry** | [TBD] |
+| **Contact** | [TBD] |
+| **Deployment** | [TBD] |
+| **Use case** | Agent fleet governance, MCP plugin allowlists |
+| **Outcome** | [TBD] |
+| **Quote** | [TBD] |
+
+**CS action:** Identify 1–2 Tier 1 candidates from pipeline targeting brief. Route to Legal for clearance within 5 business days.
+
+---
+
+## Reference Candidate C — Financial Services (Competitive Displacement)
+
+*Longer timeline — 6–8 weeks expected clearance. Start outreach now, plan for Q2 publication.*
+
+Matches CrewAI's confirmed enterprise profile (IBM, PwC, RBC). Highest competitive narrative value. Lowest near-term clearance probability.
+
+**CS action:** Identify any financial services or regulated enterprise contacts currently in active deployment (not pilot). Begin relationship-building for future case study.
+
+---
+
+## Standard Contract Clause to Check
+
+*[Legal to confirm whether the following applies to relevant contract tiers:]*
+
+> **Reference Rights:** Customer agrees that Molecule AI may reference Customer's use of the Platform in marketing materials, including but not limited to: company name, contact name, use case description, and quoted statements. Molecule AI will obtain Customer's written approval before any public reference, which approval shall not be unreasonably withheld.
+
+*If this clause exists in the AWS data engineering team's contract, named reference may already be contractually pre-approved — Legal to confirm.*
+
+---
+
+## Publication Channels
+
+Upon clearance, the approved content will be published to:
+- Molecule AI website (case studies page)
+- Phase 30 sales enablement materials (updated)
+- GTM collateral (one-pager, competitive battlecard)
+- LinkedIn / social (with customer approval for named attribution)
+
+---
+
+## Timeline
+
+| Week | Action |
+|------|--------|
+| **Week 1** | CS identifies Tier 1 candidates; sends initial outreach |
+| **Week 1–2** | Legal reviews reference rights clause; confirms minimum clearance path |
+| **Week 2–4** | Customer calls; draft brief submitted to Marketing |
+| **Week 3–5** | Legal reviews final brief; approves publication format |
+| **Week 4–6** | Brief published; Phase 30 GTM collateral updated |
+
+**If named clearance fails:** Publish anonymized version at Week 4–5; revisit named at Q2.
+
+---
+
+## Contact for This Request
+
+- **Marketing Lead:** [on file — GH#1405 assignee]
+- **Research Lead:** [this brief]
+- **CS escalation:** [CS team lead — to be identified]

+# Enterprise Case Study Pipeline Targeting Brief
+
+**Source:** GH#1398 CrewAI Enterprise Strategy + GH#1405 Enterprise Case Studies
+**Author:** Research Lead
+**Date:** 2026-04-21
+**Status:** DRAFT — for Sales/CS review
+
+---
+
+## Purpose
+
+Identify which existing Molecule AI pipeline contacts to prioritize for enterprise case study reference clearance outreach. Based on: (1) CrewAI enterprise target verticals and roles, (2) Molecule AI's existing pipeline signals, (3) reference clearance likelihood by segment.
+
+---
+
+## What We're Competing Against
+
+**CrewAI's 18 named enterprise logos** (GH#1398):
+IBM, PwC, NTT DATA, PepsiCo, RBC, DocuSign + 12 others
+
+**CrewAI's target enterprise profile:**
+- **Verticals:** Financial services, enterprise software, manufacturing, professional services
+- **Roles:** VP Engineering, Director of Developer Productivity, Chief AI Officer, Head of Platform Engineering
+- **Use case:** Multi-agent pipelines for internal tooling, code generation at scale, document processing, customer service automation
+- **Deployment:** Dedicated VPC (AMP Factory), SSO-gated, enterprise procurement
+
+---
+
+## Molecule AI's Counter-Positioning Advantage
+
+For each CrewAI target persona, identify Molecule AI's differentiation:
+
+| CrewAI Target | Molecule AI Advantage | Who to Approach |
+|---------------|----------------------|-----------------|
+| **VP Engineering / Platform** | Remote runtime: agent compute where data lives, not on CrewAI's cloud | Platform engineering leads with data residency concerns |
+| **Director of Developer Productivity** | Org-scoped API keys + audit logs: governance without sacrificing autonomy | Dev productivity teams at regulated enterprises |
+| **Head of AI / CAIO** | Multi-tenant SaaS: no infra to manage, A2A protocol works across fleet | AI offices evaluating build-vs-buy |
+| **Enterprise Sales (inbound)** | Docker + Remote mixed fleet: same Canvas, same auth, two runtimes | Companies already running self-hosted AI infra |
+
+---
+
+## Priority Outreach Segments
+
+### Tier 1 — Highest clearance likelihood, strongest narrative
+
+**1. Data engineering teams on AWS/GCP using Remote Workspaces**
+- *Why:* Already referenced in Phase 30 sales enablement ("raw data never touches Molecule AI platform")
+- *Use case:* Data pipeline agents, ETL automation, data processing
+- *Deployment:* Remote Runtime (self-managed AWS/GCP compute)
+- *Clearance likelihood:* HIGH — customer self-selected as security-conscious; likely contractually clear for technical reference
+- *Approach:* Ask for technical reference call + use case quote. Anonymize if named clearance fails.
+
+**2. Enterprise platform teams evaluating AI governance**
+- *Why:* Org-scoped API keys + audit logs are a differentiator vs. CrewAI's developer-tool model
+- *Use case:* Agent fleet governance, MCP plugin allowlists, compliance reporting
+- *Deployment:* Hybrid (Canvas + Remote)
+- *Clearance likelihood:* MEDIUM-HIGH — governance buyers are often more comfortable with references
+
+**3. AI-first startups / mid-market companies with active dev teams**
+- *Why:* Faster sales cycle, more likely to have named contacts willing to go on record
+- *Use case:* Multi-agent development pipelines, autonomous code review, CI/CD integration
+- *Deployment:* Molecule AI Cloud or self-hosted
+- *Clearance likelihood:* MEDIUM — faster to close, but may lack enterprise legal process
+
+### Tier 2 — Valuable but harder to clear
+
+**4. Financial services / regulated enterprises (matching CrewAI's IBM/PwC/RBC profile)**
+- *Why:* Same vertical as CrewAI's confirmed wins — strongest competitive displacement narrative
+- *Use case:* Compliance automation, document processing, internal tooling
+- *Clearance likelihood:* LOW in near term (FedRAMP, SOC 2, internal legal review) — start outreach now but expect 6–8 weeks
+
+---
+
+## Recommended First Move
+
+**Approach the AWS data engineering team first** (Tier 1, #1 above):
+- Anonymized reference already exists in sales materials — customer is presumably aware they may be referenced
+- Technical use case is documented (pipeline agents, AWS, Remote Runtime)
+- Self-selected for data security narrative — strongest Molecule AI proof point
+- Clearance: start with CS contact asking for "technical reference call" before mentioning public use
+
+**Script for CS initial outreach:**
+> "We're preparing a technical case study for our Phase 30 launch and we'd love to feature the work your team is doing with [use case]. This would be a short [named/anonymized — their choice] overview of what you deployed and the outcome. Legal clearance typically takes 2–3 weeks — we're starting now so we're ready for launch. Would your contact be open to a 20-minute call with our marketing team?"
+
+---
+
+## What to Capture on the Call
+
+For each reference candidate, collect:
+1. **Named customer** (company + contact name + title) OR explicit anonymization approval
+2. **Use case:** What problem, what Molecule AI features, how many agents/users
+3. **Deployment model:** Cloud / self-hosted / hybrid; backend infrastructure
+4. **Outcome metric:** Even directional ("reduced X by ~70%") is useful
+5. **Quote:** 1–2 sentences on what problem they solved and why they chose Molecule AI
+6. **Approval:** Email confirmation from legal or contact for marketing to reference
+
+---
+

+# Staging SaaS E2E — runbook
+
+Four workflows + a shared bash harness that together cover the SaaS stack end to end against live staging. Every workflow provisions a fresh org per run and tears it down; leaks are CI failures.
+
+## Coverage
+
+| Workflow | Cadence | Wall time | Scope |
+|---|---|---|---|
+| `e2e-staging-saas.yml` | push + nightly 07:00 UTC | ~20 min | Full API: org → tenant → 2 workspaces → A2A → HMA → delegation → leak check |
+| `canary-staging.yml` | every 30 min | ~8 min | Minimum smoke + self-managed alert issue |
+| `e2e-staging-canvas.yml` | push + weekly Sunday 08:00 | ~25 min | All 13 canvas workspace-panel tabs via Playwright |
+| `e2e-staging-sanity.yml` | weekly Monday 06:00 | ~10 min | Intentional-failure: teardown safety-net self-check |
+
+`tests/e2e/test_staging_full_saas.sh` is the shared harness all workflows invoke (with `E2E_MODE={full|canary}` and `E2E_INTENTIONAL_FAILURE={0|1}` toggles).
+
+### Full-SaaS checklist (sections)
+
+| # | What |
+|---|---|
+| 0 | CP preflight |
+| 1 | `POST /cp/admin/orgs` — org create without WorkOS session |
+| 2 | Wait for tenant status = running |
+| 3 | `GET /cp/admin/orgs/:slug/admin-token` — fetch per-tenant bearer |
+| 4 | Tenant TLS readiness on `/health` |
+| 5 | Provision parent workspace |
+| 6 | Provision child workspace (full mode) |
+| 7 | Wait both online |
+| 8 | A2A round-trip on parent — expect agent response |
+| 9 | HMA memory write + read, peers smoke, activity log (full mode) |
+| 10 | Delegation mechanics: parent → child via proxy + activity assertion (full mode) |
+| 11 | EXIT trap — teardown + leak detection |
+
+### Canvas tabs
+
+Opens all 13 workspace-panel tabs against the freshly-provisioned org:
+
+```
+chat, activity, details, skills, terminal, config, schedule,
+channels, files, memory, traces, events, audit
+```
+
+Per tab: visible, panel renders, no "Failed to load" toast, screenshot captured. Known SaaS-mode gaps (Files empty, Terminal disconnect, Peers 401) are whitelisted — see issue #1369.
+
+### Sanity self-check
+
+Runs the harness with `E2E_INTENTIONAL_FAILURE=1`, which poisons the tenant admin token after the org is provisioned. The workspace-provision step then fails and the script exits non-zero; the EXIT trap + teardown + leak assertion must still run clean. If they don't, the sanity workflow files a `priority-high` issue with label `e2e-safety-net`.
+
+## Required secret (exactly one)
+
+Set in **Settings → Secrets and variables → Actions → Repository secrets**:
+
+### `MOLECULE_STAGING_ADMIN_TOKEN`
+
+The `CP_ADMIN_API_TOKEN` env currently set on the Railway staging molecule-platform → controlplane service.
+
+```
+railway variables --environment staging --service controlplane --kv | grep CP_ADMIN_API_TOKEN
+```
+
+This **one** secret drives everything:
+
+- `POST /cp/admin/orgs` — provision org (no WorkOS session needed)
+- `GET /cp/admin/orgs/:slug/admin-token` — fetch per-tenant bearer
+- `DELETE /cp/admin/tenants/:slug` — teardown
+- `GET /cp/admin/orgs` — leak detection post-teardown
+
+The per-tenant admin token (short-lived, per-org) drives every tenant-side call (`POST /workspaces`, `/memories`, `/a2a`, etc.).
+
+**No WorkOS session cookie needed** — admin endpoints bypass session auth via `AdminGate` (bearer + rate-limit only). CI provision + teardown collapse to one credential.
+
+## Running locally
+
+```
+export MOLECULE_ADMIN_TOKEN="…"
+# Optional: keep the org for post-mortem inspection
+export E2E_KEEP_ORG=1
+bash tests/e2e/test_staging_full_saas.sh
+```
+
+`E2E_KEEP_ORG=1` skips teardown so you can poke at the provisioned tenant yourself. **Never set this in CI** — staging will fill with orphans.
+
+## Cost
+
+- Full run: ~20 min, ~$0.007
+- Canary (48/day): ~$0.06/day
+- Canvas (few/week): ~$0.01/day
+- Sanity (weekly): ~$0.002/week
+- **Total staging burn: < $0.15/day** at expected CI load
+
+Hard per-workflow timeouts (15–40 min) cap runaway cost. Three teardown layers:
+
+1. Bash `trap cleanup_org EXIT INT TERM` in the harness
+2. Playwright `globalTeardown` for the canvas workflow
+3. `if: always()` step in every workflow that greps today's `e2e-*` orgs and force-deletes them
+
+## Exit codes
+
+| Code | Meaning |
+|---|---|
+| 0 | Happy path |
+| 1 | Generic failure (agent didn't respond, provisioning hung, etc.) |
+| 2 | Missing required env |
+| 3 | Provisioning timed out |
+| 4 | Teardown left orphan resources (**leak detected — sanity workflow catches this**) |
+
+## Known gaps (tracked elsewhere)
+
+- [#1369](https://github.com/Molecule-AI/molecule-core/issues/1369): SaaS canvas Files / Terminal / Peers tabs — architecturally broken; whitelisted in the spec
+- LLM-driven delegation (autonomous `delegate_task` tool use) — probabilistic, not in v1; proxy mechanics covered

+Scrubbing
+---------
+Every text field passes through scrub_snapshot before being written.

+Storage
+-------
