v0.0.1-rc15

Evidence lineage diagnostic release.

Summary

• Add structural evidence lineage diagnostics.
• Add runtime-local user_turn_id to evidence records.
• Add produced_by_phase for known tool-call producer paths.
• Keep producer_model_call_id null for now.
• Preserve existing evidence rendering and selection behavior.
• No prompt, routing, tool loop, cache, final-policy, or evidence compaction behavior changes.

Evidence lineage

This RC adds structural lineage fields to evidence records:

• evidence_sequence
• tool_call_id
• user_turn_id
• produced_by_phase
• producer_model_call_id

producer_model_call_id remains null until a reliable runtime-side producer model-call id exists.

The lineage is diagnostic/structural. It is not used for relevance selection yet.

Smoke findings

Clean-workdir smoke confirmed:

• shell_error: PASS
• dual_shell: PASS
• evidence lineage is populated
• dual_shell still includes both needed cards
• no evidence selection or compaction behavior changed

The earlier evidence-lineage smoke failure was caused by persistent evidence-store contamination plus a tight timeout, not a runtime regression.

Validation

• Targeted unit gates: PASS
• Full unit gate: PASS, 973 tests
• KV/final token reduction smoke: PASS
• MTP strict smoke: PASS
• Timeout/cancel recovery smoke: PASS
• Evidence lineage smoke with clean workdirs:
  • shell_error: PASS
  • dual_shell: PASS
• git diff --check: PASS
