0.8.8 EXP-OBS (Slice 5) — query-level retrieval trace. Reuses the existing search_reranked knobs + the active embedder identity; timings are coarse per-stage wall-clock (monotonic) captured only on the explain path.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

query_chars: u32

Query LENGTH only (chars) — never the query text (privacy; ADR §C).

k: u32

Final result limit (SEARCH_RERANK_LIMIT-derived final_limit).

rerank_depth: u32

pool_n: u32

alpha: f64

use_graph_arm: bool

recency: bool

Recency reweight (the dedicated G12 flag) was applied.

embedder_id: String

Active embedder identity name@revision (+ dim), or empty when none.

ce_active: bool

The CE cross-encoder actually reranked the pool (model loaded + depth>0).

vector_hits: u32

Per-arm input hit counts (pre-fusion).

text_hits: u32

graph_hits: u32
