+# 2026-02-13 - DevPlan Bug Fixes Session
+
+## Summary
+Working through batch of bugs from testing (#137-#143, #146). PR #144 merged with 7 fixes.
+
+## Completed Today
+- PR #144 merged: #130, #125, #126, #137, #138, #141 fixes
+- Branch `fix/feature-grouping-146` created - fixes feature grouping regression
+- #146 root cause: `groupRelatedFeatures` only pushed groups that had items (endpoints), but features without endpoints are valid phases too
+
+## Active Work
+- **Branch:** `fix/feature-grouping-146` (builds pass, ready for PR)
+- **Remaining bugs:** #139, #140, #142
+
+## Bug Analysis
+### #139 - CLAUDE.md ignores detected language
+- `getLanguageDefaults` imported at line 12, called at line 222
+- Language param passed but defaults not applied correctly
+- Need to trace how language flows through generator pipeline
+
+### #140 - Nonsensical file paths
+- `.txt` extensions, Python naming conventions for Java projects
+- Same root cause as #139 - language defaults not propagating
+
+### #142 - Irrelevant lessons in plans
+- Graph API/Cargo/RocksDB lessons appearing in Java plans
+- Decision: Infer language from lesson content rather than add `languages` field
+
+## Key Files
+- `src/generators.ts` - main plan generation logic
+- `src/language-defaults.ts` - language-specific defaults
+- `src/adapters/claude.ts` - CLAUDE.md generator
+- `src/templates.ts` - template system
+
+## Next Session
+1. Create PR for #146 fix
+2. Fix language propagation in generators (#139, #140)
+3. Filter lessons by inferred language (#142)
