Adds 5 new pattern files covering the core Ecto APIs, each with real
source citations at commit fd2ec52b, before/after examples, anti-patterns,
and decision trees.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Every source reference now links to elixir-lang/elixir at commit f4e1b34.
122 hyperlinks across 11 topic files. Added PATTERN_COMPLETE sentinels.
Removed from-source.md (326 lines, shallow) — covered by existing files.
Using codebase-analysis skill (patterns mode) on the language source.
Real examples from the repo, not invented. Each pattern has:
- Rule, Example, Why, When NOT to use, Source file.
Topics: module org, protocol design, error handling, testing,
documentation, naming, process design, smells.
Extracted patterns, conventions, and code smells directly from the
Elixir and Phoenix source code with file path and line number citations.
Covers: GenServer, error handling, data transforms, process design,
testing, documentation, typespecs, macros, behaviours, module organization,
Phoenix-specific patterns, framework deviations, and anti-patterns.
