Module temporal 

Temporal Command - Temporal Constraint Mining

Mines temporal constraints (method call sequences) from a codebase.

Algorithm

1. Extract method call sequences from each function
2. Build frequency table of (before, after) pairs (bigrams)
3. Calculate confidence: count(A->B) / count(A)
4. Filter by min_support and min_confidence
5. Optionally mine trigrams (3-method sequences)

TIGER Mitigations

• T05: MAX_TRIGRAMS=10000 with BinaryHeap top-K selection
• E03: –timeout flag (default 60s)

Example

# Mine constraints from a directory
tldr temporal src/ --min-support 2 --min-confidence 0.5

# Filter for specific method
tldr temporal src/ --query open

# Include trigram patterns
tldr temporal src/ --include-trigrams
