ContextLattice v3.11.2 - Sparse Evidence Preservation

v3.11.2 fixes the last-resort Context Pack boundary so constrained output remains useful, not merely schema-valid. When a full pack exceeds its output contract, ContextLattice now preserves a compact kernel of the highest-ranked evidence and builds deterministic synthesis from it.

What changed

• Forced-minimal Context Packs retain up to four compact ranked evidence cards instead of replacing all evidence with an empty list.
• Lower-value and duplicated prompt-section structure is compacted around that evidence kernel.
• The reference prompt is rebuilt from the evidence-preserving sparse pack.
• Compiler and token-budget metadata now distinguish pre-boundary selection counts from the evidence actually returned.
• Added regression coverage proving the sparse pack stays under contract while producing non-empty deterministic synthesis findings and evidence trails.

Boundaries preserved

• Output size, string length, and list limits remain enforced.
• Evidence order remains the impact-ranked order selected by the context allocator.
• Synthesis remains deterministic with llm_used=false.
• No raw logs, provider overflow payloads, secrets, or unbounded artifacts are introduced.
