fix(SESF-97): lower the default hybrid recency weight to 0.15 - #102
After deploy: eval_retrieval.py run --env SESSIONFLOW_RECENCY_WEIGHT=0.15 should match the sweep row for 0.15.
Version: 0.9.1 (patch): a default value changes; no tool, parameter or env var changes.
Summary by CodeRabbit
Updates
The default recency weight in hybrid search is now 0.15 when SESSIONFLOW_RECENCY_WEIGHT is not set, down from 0.3. This changes how recency contributes to result ranking; explicitly configured weights are unaffected.
This release is version 0.9.1.
The changelog now includes retrieval-evaluation scores for this release.
The SESF-82 sweep over the 77-query eval set scored the old default 0.3
no better than weight 0 overall (MRR 0.630 against 0.631), and it cost
paraphrase queries most (MRR 0.729 against 0.917 at 0.15). Weight 0.15
scored best overall: MRR 0.654, nDCG@10 0.623.
The default hybrid ranking recency weight changes from 0.3 to 0.15. Test expectations and the stub fixture use the new value. The changelog and package version are updated for release 0.9.1.

Explanation
The title names the primary change: lowering the default hybrid recency weight to 0.15. The raw summary and PR objectives both confirm that RECENCY_WEIGHT_DEFAULT moves from 0.3 to 0.15, with matching test, fixture, changelog, and version updates. The 'fix(SESF-97):' prefix follows a conventional-commit style and adds a ticket reference, which is acceptable.

Test the production default instead of only the stub.
This assertion uses stub_rag_engine, so it can pass even if rag_engine.RECENCY_WEIGHT_DEFAULT remains 0.3. Add a focused test that clears SESSIONFLOW_RECENCY_WEIGHT and calls the real rag_engine.ranking_settings().
As per path instructions, tests must contain meaningful assertions.
