Round-7 claude-review (no blockers):
- 🟡 query_token_count/query_embedding were class-level defaults on
SearchAlgorithm, relying on each subclass's __init__ to shadow them. Added
SearchAlgorithm.__init__ that sets both as instance attributes and had
BM25HybridSearchAlgorithm + SemanticSearchAlgorithm call super().__init__(),
so per-request concurrency isolation is structural, not by convention.
- 🟡 Documented the v1 search-path billing gap: record_search_usage fires only
on a fully successful search, so if the query embed succeeded (provider billed
+ Prometheus recorded) but a later step (Qdrant/verify) raised, no
tokens_embedded billing row is written. Added a NOTE at the call site.
Left as-is (reasons in PR reply): deployment sequencing (CP METRIC_EVENT_NAMES
already renamed; pipeline inert); Ollama _detect_dimension double dimension-set
(idempotent, same value); SonarQube issues — 1 is the deliberate TODO(#282)
(INFO), 4 are S7503 false positives on async test stubs that must be awaitable
(gate green).
Deck #284.
