+## Background
+
+`investigator` was introduced by prior AI-driven Ticket orchestration design as a fixed Ticket role alongside `intake`, `orchestrator`, `coder`, and `reviewer`. It was not part of the current desired role profile set, and the former TUI `:ticket investigate` surface has already been removed.
+
+Investigation/read-only research remains useful, but it should be modeled as a task-specific helper Pod spawned by Intake/Orchestrator/preflight when needed, not as a permanent fixed Ticket role with workspace config/profile slots.
+
+## Goal
+
+Remove `investigator` as a fixed Ticket role and clean up user/project-facing references while preserving the ability for Orchestrator/preflight flows to spawn read-only investigation helper Pods as ordinary task-specific Pods.
+
+## Requirements
+
+- Remove `TicketRole::Investigator` from the fixed role model.
+- Update Ticket config parsing/scaffold/defaults so `.yoi/ticket.config.toml` only requires/advertises:
+  - `intake`
+  - `orchestrator`
+  - `coder`
+  - `reviewer`
+- Treat `[roles.investigator]` in current config according to the project’s desired compatibility policy; prefer a clear config error or documented migration over silently using an unsupported role.
+- Update launcher/client/TUI tests and prompt generation that currently mention or branch on `Investigator`.
+- Remove docs/workflow wording that presents `investigator` as a fixed role or configured role slot.
+- Preserve wording/behavior that allows Orchestrator/preflight to create read-only helper Pods for investigation when explicitly useful.
+- Do not reintroduce the removed TUI `:ticket investigate` command surface.
+- Do not add a generic arbitrary role registry as part of this cleanup.
+
+## Acceptance criteria
+
+- No runtime fixed-role enum/config/scaffold path exposes `investigator` as a Ticket role.
+- `yoi ticket init` no longer emits `[roles.investigator]`.
+- Project docs describe investigation as an optional helper-Pod activity under Intake/Orchestrator/preflight, not a configured Ticket role.
+- Existing Ticket role launch flows for intake/orchestrator/coder/reviewer still work.
+- Focused tests for `ticket::config`, `client::ticket_role`, and any affected TUI role-launch/panel paths pass.
+- `target/debug/yoi ticket doctor`, `cargo fmt --check`, and `git diff --check` pass.
