 > **Merged-main canary update (2026-07-23, run `30018289898`):** the new structured report correctly recorded evaluated tree `c24f2e8f2d30d0c59fc1eba025d3dcd63478137e`, run/attempt identity and `cross-region-runner` latency context. Golden retrieval remained 36/36 with document/content recall 1.0 and no failed cases. The 44-case answer gate had grounded-supported and unsupported-correct rates of 1.0, but failed because `neuroleptic-side-effect-escalation` again returned one citation where two are required (citation-failure rate 0.0227). `admission-discharge-comparison` again omitted the specific AKG admission document after `comparison_source_extractive_fallback`; `admission-discharge-coverage-paraphrase` was advisory-only at 24,870 ms. Answer cost was reported as `$0.234736`. Do not retry immediately: retain this as the first structured datapoint, compare it with the scheduled 2026-07-26 report, and keep retrieval/ranking unchanged.

+> **Scheduled comparison preflight (2026-07-24, read-only):** GitHub run inventory confirms the requested Sunday 2026-07-26 18:00 UTC artifacts do not exist yet. The latest scheduled Eval Canary is run `29699878841` (2026-07-19), the latest scheduled CI/browser matrix is run `29700014531` (2026-07-19), and the prior structured baseline artifact from run `30018289898` remains available. Rereading that baseline confirms 36/36 retrieval, document/content recall 1.0/1.0, MRR@10 0.8921, irrelevant-source-rate@10 0.0917, answer p95 18,591 ms, one blocking provider citation failure, the post-retrieval admission-source loss tracked by #019, and one advisory cross-region latency case. There is no second datapoint, so no deterministic/provider/latency delta or residual disposition is valid yet. Keep #023/#051 open and Groups F-H no-go; do not dispatch, spend, tune RAG, or substitute the later branch dispatch for the scheduled-main datapoint.

 > **RAG reconciliation correction (2026-07-23):** fresh current-main live evidence supersedes the broad diagnosis in #018. The three named misses are not one composer defect. Lithium reproduced an unrelated-table retrieval fast-path defect; ADHD still retrieves a relevant chart-heavy CAMHS source but exhausts the extractive route budget; metabolic retrieves the correct AKG source but selects schedule-free prose; #019 remains post-retrieval comparison source selection. A narrow lithium subject-evidence guard improved its targeting result from 0 to 1 with golden recall 1.0 and no reciprocal-rank regressions, but was reverted and rejected because the required full canary failed. Keep #029 open for the remaining fallback-stub cases. Do not combine these residuals or change ranking scores, comparator ordering, aliases, clamps, or semantic reranking without a separate reproducer and passing canary pair.
