Section titled “std:logging/Level”

Canonical occurrence: protos/lib/logging/Level.protos · Protos revision: e99b712ecf658a527b1fe82c8beba2c1286d8dc9.

Canonical logging severity levels. The five levels, in ascending order of severity, are TRACE, DEBUG, INFO, WARN, and ERROR. Each level is its canonical String value: Level.INFO is exactly "INFO", so a level is immutable, compares with === and ==, and keeps its identity across Actor, Task, and Process boundaries without any shared registry.

There is no FATAL level: logging reports severity and never implies terminating a Process. Severity order is observed only through compare; no numeric rank is part of the public contract.

Observable top-level slots

Section titled “Observable top-level slots”

This page lists the complete mechanically observable top-level slot inventory required by D067. Authored documentation, when present, is canonical D062 prose; mechanical presence alone does not create a stability or compatibility promise.

DEBUG

Section titled “DEBUG”

Detailed diagnostics intended for debugging.

compare

Section titled “compare”

Answers -1, 0, or 1 as level left is less severe than, equal to, or more severe than level right. Both arguments must be canonical levels; any other value signals an Error. Arguments are recognized by String identity only, so no behavior of an argument is invoked.
