CodeMetricsConfig.txt

# Thresholds for the CA15xx code-metrics rules (CA1501, CA1502, CA1505, CA1506).
#
# This file MUST be named exactly "CodeMetricsConfig.txt" - the analyzer matches on the
# file name of the AdditionalFiles item, not on item metadata. It is wired up for every
# project by the <AdditionalFiles> entry in Directory.Build.props.
#
# The .editorconfig key `dotnet_code_quality.CA1502.threshold` does NOT exist; setting it
# has no effect and the rule silently keeps its default of 25. Verified empirically
# against the analyzers in SDK 10.0.301.
#
# Format:  <RuleId>: <threshold>
# Optional symbol-kind scoping: <RuleId>(Method|NamedType|Namespace|Assembly): <threshold>
# A malformed entry is reported as CA1509 rather than silently ignored.
#
# Semantics (measured, not assumed):
#   CA1501 / CA1502 / CA1506 fire when the value is STRICTLY GREATER than the threshold.
#   CA1505 is inverted: it fires when the maintainability index is STRICTLY LESS THAN it.

# ---- Cyclomatic complexity -------------------------------------------------------------
# 15 means "a method may have a complexity of at most 15"; the first value that reports
# is 16. Confirmed with a probe containing methods of complexity 11..21: complexity 15
# stayed silent, complexity 16 reported.
CA1502: 15

# ---- Maintainability index -------------------------------------------------------------
# Microsoft's bands: 0-9 red, 10-19 yellow, 20-100 green. The analyzer default is 10,
# which only trips on already-catastrophic code. 20 puts the gate on the green/yellow
# boundary instead, so "moderate maintainability" is a failure rather than a shrug.
# Costs nothing today: the worst maintainability index anywhere in the repo is 32.
CA1505: 20

# ---- Depth of inheritance / class coupling ----------------------------------------------
# Left at the analyzer defaults (CA1501 > 5, CA1506 > 95 for types / > 40 for members).
# CA1501 is switched off for src/WhisperNotes.App/Views in .editorconfig, where the depth
# comes entirely from Avalonia's own control hierarchy and cannot be refactored away.
# CA1501: 5
# CA1506: 95
