release: v1.108.177 — an omitted match is not an absent match #126

	name: Replay

	# Retrieval-quality regression gate. Indexes this repo, replays a fixed set of
	# golden queries through search_symbols, and fails if nDCG / MRR / Recall@k drop
	# more than 2% (relative) below the committed golden baseline. This is the gate
	# that lets ranking-affecting changes (fusion weights, BM25 normalization, parser
	# extraction) land with a proof they did not regress retrieval quality.
