==================

Bugfixes

• Generating a report no longer crashes when the coverage universe contains a module that shadows #inspect with an incompatible signature. Rendering a method coverage key's receiver calls to_s, and a singleton class's to_s renders its attached object via #inspect — Liquid's Utils module defines inspect(value, max_depth = 2) as a module_function, so any suite whose report included Liquid's files (typically a vendored bundle under the project root, which is why this surfaced only in CI) raised ArgumentError from the at_exit hook and lost its report. The exposure predates 1.0.2's key normalization, which only moved the call. Rendering now recovers by rebuilding the name from Module#name via bound methods, which user code cannot shadow, falling back to an address form that the existing normalization collapses. The external_at_exit workaround is no longer needed. Reported with an exemplary diagnosis by @​bkuhlmann. See #​1236.
• Method coverage entries are now aggregated by source location alone, completing the aggregation introduced in 1.0.2 (which keyed on name and location). Ruby records one method entry per defined method, so a builder looping container.each_key { |key| define_method(key) { ... } } produces an entry per generated name, all at the block's location — and every name whose generated wrapper no test happened to call showed as an uncovered method on a line with full line and branch coverage. A source location is the unit a file-based report can express, and regular defs map one location to one name, so they are unaffected. The same identity is used when merging resultsets across processes. This also covers methods copied into refinements via import_methods, which Ruby records once per importing refinement at the shared module's original location, so exercising the method through any refinement now marks the shared definition covered and the skip workaround for shared refinement modules can be dropped. Reported with exemplary diagnoses by @​bkuhlmann. See #​1234 and #​1237.
• SimpleCov.formatter and SimpleCov.formatters now accept formatter instances in addition to formatter classes, so constructor options can actually be passed — most notably SimpleCov::Formatter::HTMLFormatter.new(silent: true) to suppress the "Coverage report generated" status line. Previously SimpleCov unconditionally called .new on whatever was configured, so passing an instance crashed with NoMethodError at report time. See #​1240.

Performance

• Fix 5x performance regression on report combining (introduced in 1.0.0 as a result of using Ripper#parse in a hot path) by adding parsed key memoisation to RubyDataParser.call.
