+//! Synchronizes moderation thread messages and dummy queue blockers with the
+//! current computed tech review state of affected projects.
+//!
+//! When a project has a Delphi report submitted for it, or when a moderator
+//! updates one of its issue details' rows (like flagging a detail as *globally*
+//! safe or unsafe), we will need to recheck if the project still belongs in the
+//! tech review queue or if it needs to exit now.
+//!
+//! Side-note: "entering the queue" or "exiting the queue" right now just means
+//! adding a new message to the project's moderation thread which indicates if
+//! it entered/exited. In the future this should be replaced with a more proper
+//! audit log table, or "is project currently in tech review" table.
+//!
+//! A project is considered to need tech review when it has at least one
+//! non-dummy issue detail whose effective status is pending or unsafe, or when
+//! it already has a dummy pending detail blocking the final review submission.
+//! Effective status is just the local detail's verdict (from
+//! `delphi_issue_detail_verdicts`), or if it's null then the global verdict for
+//! the same `drid.key` (from `delphi_global_detail_verdicts`).
+//!
+//! Some examples of how this behavior manifests: let's assume you have projects
+//! _A_ and _B_ currently in tech review. They each have one (unresolved) issue
+//! detail with key _K_.
+//! - If you mark _K_ on _A_ as locally safe/unsafe, then _A_ is fully resolved,
+//!   but we still have the `__dummy` detail, which means it's still in the
+//!   queue until the moderator submits the actual report. _B_ is entirely
+//!   unaffected.
+//! - If you mark _K_ on _A_ as globally safe, then _A_ and _B_ both get fully
+//!   resolved, but both still have the `__dummy` detail, so they also still
+//!   need the final report to be submitted by the moderator.
+//!
+//!   In practice, this means that some projects may have e.g. "100/100 traces
+//!   are safe" reported, but they will just be waiting for final moderator
+//!   approval.
+//!
+//! The logic for checking whether a project is now in tech review or not, and
+//! sending the appropriate message, is complex! That's why this module exists:
+//! to act as a single chokepoint which (correctly) syncs all the state, instead
+//! of having each mutation run its own ad-hoc update logic.
