The DAG-level idiom pass in src/ops/idiom.c walks `inputs[]` only, which never reaches the aggregator subtrees that live in OP_GROUP's ext->agg_ins[]. As a result, (first (asc v)) / (last (asc v)) / (count (asc|desc|reverse v)) survived into the per-group dispatcher, which can't run a sort-wrapper inside an aggregator slot — domain error. Mirror match_count_distinct's pattern: add simplify_agg_idiom that runs at the AST stage in the select-by planner, before agg_ins[] is built.

When the inner expression returns a RAY_LAZY (e.g. (reverse v) wraps a fresh lazy chain), the cell is a deferred DAG node. Symptom: full-table display works (table-level fmt_obj walks each cell, calling ray_lazy_materialize), but extracting the column via (at table 'col) returns a LIST whose cells all read as `error: nyi`. Root cause: ray_lazy_materialize takes ownership of the graph — even if the lazy ray_t survives via shared refs, the graph itself is freed. After the first fmt of the whole table consumed the graph, every subsequent re-read of any cell hits a half-dead lazy whose execute fails inside the DAG VM with "nyi". Fix: materialise lazy cells eagerly in nonagg_eval_per_group_core before storing. Each cell is now a concrete typed-vec / atom — safe to read any number of times. Repro / regression test: test/rfl/query/list_col_at_extraction.rfl verifies both (a) full-table display and (b) repeated column-cell reads via (at (at table 'col) i) return the same concrete vec.

Three findings documented inline (no test-routing-around). - rfl/group/reprobe_stress.rfl (30 assertions) Tests the per-group dispatch reprobe path that activates only when n_groups > 65536 (commit 91531da8 fix(group): per-group dispatch survives n_groups > 65536). Covers ray_median_per_group_buf, ray_topk_per_group_buf at >= 65k groups, reprobe_rows_fn, group_ht_insert_empty_group, group_rows_range_existing, group_probe_existing_entry. Multi-key (k1+k2) wide-key SYM arm also exercised. Single-thread baseline (~50k groups) confirms the smaller path still works. - rfl/datalog/graph_algos_advanced.rfl (48 assertions) PageRank (hub-dominance, rank-sum normalisation, 1/2/3-arg variants), Louvain (community detection), var-expand realloc paths (frontier 256->2048, out_count 1024->2048). Finding (documented inline, NOT routed around): Louvain returns 4 communities of size 2 for the canonical K4+K4+bridge fixture, not 2 — src/ops/traverse.c:1166 self-documents this as "Pass 1 only (no graph contraction)". Assertions encode the observed 4-communities output + the cross-cluster invariant that still holds; any future phase-2 addition will trip these and force a re-evaluation. Finding (out of scope): exec_astar is implemented at src/ops/traverse.c:2213 but has no RFL binding (no ray_graph_astar_fn, no .graph.astar registration). SCC has zero implementation in the tree. Both unreachable from RFL — needs source wiring before a regression test makes sense. - rfl/temporal/cross_cast_period.rfl (106 assertions) Cast matrix DATE/TIME/TIMESTAMP -> each other (atom + vector), boundary dates (epoch, Y2K, leap day, pre-Y2K, century-non-400 2100), DOW grid Mon-Sun, DOY for leap + non-leap. Covers ray_temporal_truncate atom + vec branches (int32 + int64 input), pre-epoch us<0 floor-toward-negative-inf arithmetic, rte_us_to_ts_raw, ray_*_clock_fn temporal-argument overload, cross-temporal casts in builtins.c (DATE<->TIMESTAMP, TIMESTAMP->TIME, String->DATE/TIME). Note: HAS_NULLS arm not reachable from literal vectors (needs csv load); date_trunc MINUTE/HOUR/MONTH/YEAR arms are dead at surface per ray_temporal_trunc_from_sym registering only DAY+SECOND. - rfl/strop/like_patterns.rfl (71 assertions) exec_like / exec_ilike compiled-shape branches: EXACT, PREFIX, SUFFIX, CONTAINS, ANY, GLOB (? char-class [...] multi-* mixed) x STR-vec + SYM-vec x like + ilike + scalar. Edge cases: empty pattern, empty input rows, pattern longer than every input, case-insensitive ilike on both pattern cases. Drives the SYM dict-cache branch (seen[]/lut[] first-touch + reuse). - rfl/query/where_and_chain.rfl (59 assertions, 1 XFAIL) Chained-filter compiler (commits 5205265d cost-based reorder, b406422d compile chained, 7f1d46e0 fused rgid_probe selection). 3- and 4-conjunct AND over 50k rows, cost reorder, reorder_safe=0 short-circuit-preserving guard, mixed agg+non-agg projection over a filtered rowsel, predicate pushdown past projection, semijoin via (in col ...), single-conjunct AND. Finding (XFAIL, Bug 4): `(and X)` single-conjunct returns error: domain. src/ops/query.c:4060 chained-filter branch requires ray_len(where_expr) >= 3 (and-head + >= 2 conjuncts), so degenerate (and X) falls through to compile_expr_dag which returns NULL. Planner should fold (and X) -> X before compile. Marked with !- domain and a paired (> v 100) form proving the un-wrapped predicate works. Tests: `make clean && make test` -> 2528 of 2530 passed (2 skipped, 0 failed).
