Teo already refused event creation in code for people without permission, but the check let in anyone with Discord's own event or administrator permission and five roles (Admin, ATR Alchemist, Professor, Researcher, ATR lab staff). Now only the Researcher role counts.

• may_create_events checks only TEO_EVENT_ROLE_IDS, now just the Researcher role (809299070137008158). Administrator and event permissions no longer count. If no roles are set, nobody can create events.
• create_event fetches the member from Discord again just before creating the event, so a role removed partway through a conversation still counts.
• The prompt, README and refusal text say "Researcher role". The model can't get around this, because the tool refuses no matter what the model asks.
• Tests: role only, admin alone refused, empty config refused, DMs and other servers refused, the re-check before creating, and the deployed settings.

Walkthrough

Scheduled-event creation now requires a configured role in the configured guild. The deployed setting names the Researcher role. Before creating an event, the bot fetches the member’s current guild record and checks eligibility again.

Changes: Scheduled-event role eligibility

Layer / File(s)	Summary
Configure and enforce role eligibility teo/config.py, deploy/settings.env, teo/bot.py, README.md, teo/prompt.md, teo/actions.py, tests/test_bot_helpers.py	Event eligibility requires a configured role in the configured guild. The deployed setting names the Researcher role. The documentation and denial message describe this requirement. Tests cover eligible and ineligible members, empty role settings, DMs, other guilds, and the deployed setting.
Recheck membership before event creation teo/bot.py, tests/test_bot_helpers.py	Before processing event details, create_event fetches the current guild member record. It raises a ValueError if membership cannot be confirmed or the member no longer meets the role rule. A test verifies that scheduled-event creation is not called when the role is missing.

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: Minimal · up to 03cb4

Event creation is now limited to the Researcher role and is re-checked right before the event is created. Documentation and settings match the new rule. No merge-blocking risk remains.

Security architecture risk: Low · up to 7d197

The change narrows event-creation authority and adds a fresh membership check. No new authorization bypass was identified in the inspected path. The live role identity and deployed configuration were not independently verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The inspected privileged operation affects scheduled events in one configured guild. Documentation also describes a lab board that displays Deadline:-prefixed server events, so that documented downstream display inherits the event-creation gate. The board implementation and its effective deployment were not inspected.

Security Findings and Attack Paths

• observed — In the inspected event-tool path, tool arguments cannot replace the requester or override authorization. The dispatcher rejects an ineligible action context, and the creation method independently checks freshly fetched membership before either sink branch. This supports rejection of an introduced argument-driven authorization bypass in this path, not a claim about uninspected surfaces.

Trust Boundaries and Controls

• observed — The application separates requester identity, configured policy, and event payload. Discord membership supplies current roles; environment-derived role IDs define authorization; event arguments supply content and location. Authority is enforced in code rather than relying on instructional text.

Resilience and Maintainability Implications

• observed — Unavailable guild, membership-fetch failure, failed authorization, and input-validation failures precede event creation. The membership check is nevertheless a point-in-time check, not atomic authorization at Discord's write. As in the base, creation has no application-level idempotency key or reconciliation after ambiguous completion; concurrency or retries can therefore produce multiple events. These limitations were not introduced or worsened by this PR.

Hardening Proposals

• proposed — Verify that the selected ID still identifies the intended Researcher role in the configured guild, and verify the effective role list alongside the code version during deployment or rollback. This would address the remaining operational policy uncertainty without treating it as an observed vulnerability.

Pre-merge checks: 4

Check name	Status	Explanation
Title check		The title clearly and concisely describes the main change: restricting server-event creation to the Researcher role.
Description check		The description explains the changes and lists test coverage. It does not complete the template checkboxes or confirm that the diff contains no secrets, but it is mostly complete.
Linked Issues check		Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check		Check skipped because no linked issues were found for this pull request.

Add a test for the fetch_member failure path.

The re-check test covers only a member who lost the role. It does not cover fetch_member raising discord.HTTPException. That path must refuse the request and must not call create_scheduled_event. Add a test for it.
