root 77a3dcf266 cutover: first end-to-end coordinator query against persistent Go stack 
Three real-shape demand queries against the long-running 11-daemon
stack with 500 workers ingested from workers_500k.parquet (real
production data). Substrate is producing useful answers:

Q1 (Forklift @ Aurora IL): 5/5 role match, top 3 in IL, dist 0.44-0.46
Q2 (CNC @ Detroit MI):     top-1 in Detroit MI exactly, role pulls
                           Machine Operator (semantic neighbor)
Q3 (Warehouse @ Indianapolis IN): top-1 in Indianapolis IN, 5/5 role
                                  match, dist 0.42-0.54

This is the FIRST end-to-end coordinator-shape query against the
persistent Go stack — every prior reality test (real_001..real_005)
ran through harness-transient stacks that died on exit. This one
ran against daemons that have been up for minutes and stayed up
through retrieval.

Geo is load-bearing: top-1 city/state matched in 3/3 queries.
Embedder treats geography as a primary feature.

Q2's CNC→Machine Operator gap exposes the playbook learning loop's
purpose: judge would rate this ~3/5; the first time a coordinator
approves a Machine Operator for a CNC Operator query, that
recording starts shifting substrate behavior. That's the loop
we've been building toward — the persistent stack is now the
substrate that loop will run on.

Evidence: reports/cutover/persistent_stack_first_query.md (full
top-K tables + read on each query).

What this does NOT prove:
- Production-volume load (3 queries, 500 workers)
- Concurrent latency
- Full 5-loop substrate (this exercised retrieval only; no
  playbook recordings exist on the persistent stack yet)

Persistent stack — first end-to-end coordinator query

First real-shape demand query against the long-running Go substrate (daemons up for minutes, not harness-transient). Same shape of test as real_001..real_005 reality probes, but those all ran through playbook_lift.sh's spin-up-and-tear-down cycle. This is production-shape: stack stays up, query lands, top-K returns, operator inspects.

Setup

  • Persistent stack: 11 daemons via scripts/cutover/start_go_stack.sh
  • Workers ingested: 500 rows from workers_500k.parquet (real production data, not synthetic)
  • Index: workers corpus on vectord
  • Embed: nomic-embed-text-v2-moe (768d)
  • Distance: cosine

Three queries

Q1: Forklift Operators in Aurora IL

Need 3 Forklift Operators in Aurora IL starting at 09:00 for Parallel Machining
rank id dist name role loc
0 w-325 0.441 Angela Ruiz Forklift Operator Champaign, IL
1 w-358 0.464 Lauren Evans Forklift Operator Danville, IL
2 w-447 0.465 Raymond Alvarez Forklift Operator Bloomington, IL
3 w-153 0.490 Sandra Phillips Forklift Operator Cleveland, OH
4 w-108 0.520 Omar Cook Forklift Operator South Bend, IN

Read: 5/5 role match. Top 3 in IL (semantic neighbors of Aurora — Champaign / Danville / Bloomington are central-southern IL cities). Next 2 are OH/IN — still Midwest, reasonable geographic falloff. A coordinator looking at this would probably take ranks 0-2.

Q2: CNC Operator in Detroit MI

Need 1 CNC Operator in Detroit MI for Beacon Freight
rank id dist name role loc
0 w-175 0.492 Kevin Ruiz Machine Operator Detroit, MI
1 w-413 0.521 Daniel Hall Machine Operator Grand Rapids, MI
2 w-450 0.524 Shirley Evans Machine Operator Cincinnati, OH
3 w-105 0.603 Donna Sanchez Machine Operator Memphis, TN
4 w-162 0.615 Matthew Sanchez Machine Operator Rockford, IL

Read: Geo match perfect (top-1 in Detroit MI exactly). Role match is "Machine Operator" not "CNC Operator" — the 500-row sample probably has no exact-CNC-Operator role tag, so the embedder pulls Machine Operator as the closest semantic match. A coordinator might say "yes, Kevin's done CNC before, he counts" or might say "no, machine operator is too generic." This is exactly the kind of borderline case the playbook learning loop captures: judge rates this ~3/5; first time a coordinator approves a Machine Operator for a CNC Operator query, that recording starts shifting the substrate's behavior.

Q3: Warehouse Associates in Indianapolis IN

Need 5 Warehouse Associates in Indianapolis IN at 12:00 for Midway Distribution
rank id dist name role loc
0 w-390 0.419 Mary Hughes Warehouse Associate Indianapolis, IN
1 w-118 0.467 Patricia Allen Warehouse Associate South Bend, IN
2 w-280 0.481 Ruth Torres Warehouse Associate Chicago, IL
3 w-149 0.485 Jennifer Nguyen Warehouse Associate Des Moines, IA
4 w-151 0.544 Eric Diaz Warehouse Associate Columbus, OH

Read: Cleanest of the three. 5/5 role match, top-1 in Indianapolis IN exactly, geographic falloff (IN → IL → IA → OH) makes operational sense — coordinator could expand the search radius if Mary Hughes isn't available.

What this confirms

  1. The substrate is producing useful answers on real coordinator queries against real production data on the persistent stack. Not synthetic, not transient.
  2. Role-semantic neighbors fire as designed: when an exact role match isn't in the corpus, the embedder pulls semantic neighbors (Q2). Operator-visible fact, not silent corruption.
  3. Geo is a load-bearing feature: top-1 city/state matched in 3/3 queries — the embedder treats geography as primary.
  4. Distance distribution is tight: 0.41-0.49 across top-1 of all three queries. Healthy embedder + healthy index.

What this does NOT prove

  • Real coordinator demand traffic at production volumes (this was 3 queries against 500 workers; production is potentially 5K-500K workers + dozens of concurrent queries).
  • Latency under load (single-query latency was sub-second; concurrent load not measured).
  • The 5-loop substrate end-to-end (this exercised retrieval only; observer + pathway + matrix injection + judge gate didn't fire because no playbook recordings exist on the persistent stack yet).

State

  • Persistent stack: still up (all 11 healthy as of 2026-05-01T03:10ish CDT)
  • Workers index: populated with 500 rows
  • Logs: /tmp/gostack-logs/<bin>.log
  • Will be torn down on the next git push (smokes vs persistent pkill conflict — see header of start_go_stack.sh)
