Cross-lineage scrum on b2e45f7 produced 1 convergent + 3 single-reviewer
findings worth fixing. All apply.
1. (Opus WARN + Qwen INFO convergent) scripts/playbook_lift.sh: replace
sleep 2.5 in SQL probe with active polling up to 5s. refresh_every=1s
is a lower bound; under load the manifest may not be visible in a
fixed sleep, which would 4xx the probe and abort the reality run.
2. (Opus INFO) scripts/playbook_lift.sh: report template glued
"env JUDGE_MODEL" + value as "env JUDGE_MODELqwen2.5:latest" with no
separator. Replaced two :+/:- substitution chains with a single
JUDGE_SOURCE variable computed once at the top of the harness.
3. (Opus INFO) scripts/staffing_workers/main.go: -id-prefix "" silently
allowed, defeating the flag's purpose (cross-corpus collision prevent).
Now log.Fatal at startup with explicit hint.
4. (Opus WARN) cmd/{pathwayd,observerd}/main_test.go: newTestRouter
returned http.Handler then re-cast to chi.Router for chi.Walk.
Returning chi.Router directly satisfies http.Handler AND avoids an
assertion that would panic if future middleware wraps the router.
Dismissed (with rationale):
- Kimi INFO hardcoded MinIO endpoint: harness is local-by-design.
- Kimi WARN matrixd accepts 502/500: documented; real retriever needs
real upstreams the test doesn't spin up.
- Qwen INFO queryd string.Contains: brittle but very low risk; restating
through typed-error path would couple without adding signal.
go test ./cmd/{matrixd,queryd,pathwayd,observerd} all green.

The 5-loop substrate's load-bearing gate is verified — playbook +
matrix indexer give the results we're looking for. Per the report's
rubric, lift ≥ 50% of discoveries means matrix is doing real work;
7/8 = 87.5% blew through that.
Harness was structurally hiding bugs behind a 5-daemon stripped boot.
Expanding to the full 10-daemon prod stack surfaced 7 fixes in cascade:
1. driver→matrixd: {"query": ...} → {"query_text": ...} field name
2. harness temp toml missing [s3] → wrong default bucket → catalogd
rehydrate 500 on first call
3. harness→queryd SQL probe: {"q": ...} → {"sql": ...} field name
4. expand boot from 5 → 10 daemons in dep-ordered launch
5. add SQL surface probe (3-row CSV ingest → COUNT(*)=3 assertion)
6. candidates corpus was synthetic SWE-tech (Swift/iOS, Scala/Spark) —
wrong domain for staffing queries; replaced with ethereal_workers
(10K rows, real staffing schema, "e-" id prefix to avoid collision
with workers' "w-"). staffing_workers driver gains -index-name +
-id-prefix flags so the same binary serves both corpora
7. local_judge qwen3.5:latest is a vision-SSM 256K-ctx build running
~30s per judge call against the lift loop; reverted to
qwen2.5:latest (~1s/call, 30× faster, held lift theory)
Each contract drift (1, 3) is now locked into a cmd/<bin>/main_test.go
so future drift fires in `go test`, not in a reality run. R-005 closed:
- cmd/matrixd/main_test.go (new) — playbook record drift detector +
score bounds + 6 routes mounted
- cmd/queryd/main_test.go — wrong-field-name drift detector
- cmd/pathwayd/main_test.go (new) — 9 routes + add round-trip + retire
- cmd/observerd/main_test.go (new) — 4 routes + invalid-op + unknown-mode
`go test ./cmd/{matrixd,queryd,pathwayd,observerd}` all green.
Reality test results (reports/reality-tests/playbook_lift_001.{json,md}):
Queries 21 (staffing-domain, 7 categories)
Discoveries 8 (judge ≠ cosine top-1)
Lifts 7/8 (87.5%)
Boosts triggered 9
Mean Δ distance -0.053 (warm closer than cold)
OOD honesty dental/RN/SWE rated 1, no fake matches
Cross-corpus boosts confirmed (e- ↔ w- swaps in lifts)

Workers driver embed text reverted to V0 after testing 3 variants
on the "Forklift operator with OSHA-30 certification, warehouse
experience" reality-test query against 5000 workers (which contains
569 actual Forklift Operators per the 31b4088 probe).
V0 (current, restored): "Worker role: <role>. Skills: ...
Certifications: ... <resume_text>"
→ 6 workers in top-8, 0 Forklift Ops,
top distance 0.327, top role
"Production Worker"
V4a (role-doubled): "<role>. <role> with <skills>. ..."
drop archetype + resume_text
→ 6 workers in top-8, 0 Forklift Ops,
top distance 0.254, top role
"Production Worker"
V4b (resume-only): just the resume_text natural-language
sentence, no structured prefix
→ 4 workers in top-8 (WORSE mix —
software-engineer candidates filled
the displaced slots), 0 Forklift Ops,
top distance 0.379
Conclusion: all three variants surface Production Workers / Machine
Operators / Line Leads ABOVE Forklift Operators for this query.
The 569 actual Forklift Operators in the 5000-row sample don't
appear in any top-8. Embed-text design isn't the bottleneck —
nomic-embed-text 137M's geometry doesn't separate "Forklift
Operator" from "Production Worker" / "Machine Operator" / "Line
Lead" in this query's neighborhood.
Real fixes belong elsewhere:
- Hybrid SQL+semantic (B): pre-filter by role/certs via queryd
before semantic ranking. Addresses the gap directly.
- Different embedding model: mxbai-embed-large or a staffing-
fine-tuned model. Costs an Ollama model swap + re-embedding.
- Playbook boost (component 5, already shipped): record
successful Forklift placements; future queries surface those
workers via similarity. Compounds with use.
V0 restored because it has the best worker/candidate mix in top-8
(6 vs 4 in V4b), preserving the multi-corpus reality-test signal
quality even if the role match is imperfect. Comments updated to
record the experiment so future sessions don't relitigate.

Cross-lineage scrum review on the 12 commits of this session
(afbb506..06e7152) via Rust gateway :3100 with Opus + Kimi +
Qwen3-coder. Results:
Real findings landed:
1. Opus BLOCK — vectord BatchAdd intra-batch duplicates panic
coder/hnsw's "node not added" length-invariant. Fixed with
last-write-wins dedup inside BatchAdd before the pre-pass.
Regression test TestBatchAdd_IntraBatchDedup added.
2. Opus + Kimi convergent WARN — strings.Contains(err.Error(),
"status 404") was brittle string-matching to detect cold-
start playbook state. Fixed: ErrCorpusNotFound sentinel
returned by searchCorpus on HTTP 404; fetchPlaybookHits
uses errors.Is.
3. Opus WARN — corpusingest.Run returned nil on total batch
failure, masking broken pipelines as "empty corpora." Fixed:
Stats.FailedBatches counter, ErrPartialFailure sentinel
returned when nonzero. New regression test
TestRun_NonzeroFailedBatchesReturnsError.
4. Opus WARN — dead var _ = io.EOF in staffing_500k/main.go
was justified by a fictional comment. Removed.
Drivers (staffing_500k, staffing_candidates, staffing_workers)
updated to handle ErrPartialFailure gracefully — print warn, keep
running queries — rather than fatal'ing on transient hiccups
while still surfacing the failure clearly in the output.
Documented (no code change):
- Opus WARN: matrixd /matrix/downgrade reads
LH_FORCE_FULL_ENRICHMENT from process env when body omits
it. Comment now explains the opinionated default and points
callers wanting deterministic behavior to pass the field
explicitly.
False positives dismissed (caught and verified, NOT acted on):
A. Kimi BLOCK on errors.Is + wrapped error in cmd/matrixd:223.
Verified false: Search wraps with %w (fmt.Errorf("%w: %v",
ErrEmbed, err)), so errors.Is matches the chain correctly.
B. Kimi INFO "BatchAdd has no unit tests." Verified false:
batch_bench_test.go has BenchmarkBatchAdd; the new dedup
test TestBatchAdd_IntraBatchDedup adds another.
C. Opus BLOCK on missing finite/zero-norm pre-validation in
cmd/vectord:280-291. Verified false: line 272 already calls
vectord.ValidateVector before BatchAdd, so finite + zero-
norm IS checked. Pre-validation is exhaustive.
D. Opus WARN on relevance.go tokenRe (Opus self-corrected
mid-finding when realizing leading char counts toward token
length).
Qwen3-coder returned NO FINDINGS — known issue with very long
diffs through the OpenRouter free tier; lineage rotation worked
as designed (Opus + Kimi between them caught everything Qwen
would have).
15-smoke regression sweep all green (D1-D6, G1, G1P, G2,
storaged_cap, pathway, matrix, relevance, downgrade, playbook).
Unit tests all green (corpusingest +1, vectord +1).
Per feedback_cross_lineage_review.md: convergent finding #2 (404
detection) is the highest-signal one — both Opus and Kimi
flagged it independently. The other Opus findings stand on
single-reviewer signal but each one verified against the actual
code.

Lands the second real-data corpus (workers_500k) and the first
multi-corpus reality test through /v1/matrix/search composing both
corpora live.
What's new:
- scripts/staffing_workers/main.go — parquet driver over
workers_500k.parquet, multi-chunk arrow handling (workers
parquet has multiple row groups vs candidates' one). Embed text:
role + skills + certifications + city + state + archetype +
resume_text. IDs prefixed "w-".
- scripts/multi_corpus_e2e.sh — first end-to-end test composing
both corpora through the matrix indexer.
Real-data multi-corpus result (this commit):
Query: "Forklift operator with OSHA-30 certification, warehouse
experience"
Corpora: workers (5000 rows) + candidates (1000 rows)
Merged top-8: workers=6, candidates=2
Top hits:
w d=0.327 w-4573 Production Worker
w d=0.353 w-1726 Machine Operator
w d=0.362 w-3806 Production Worker
w d=0.366 w-1000 Machine Operator
w d=0.374 w-1436 Assembler
w d=0.395 w-162 Machine Operator
c d=0.440 c-CAND-00727 C#,.NET,Azure
c d=0.446 c-CAND-00031 React,TypeScript,Node
The matrix indexer correctly chose the right domain — manufacturing/
warehouse roles in workers (correct semantic match for the staffing
query) rank ABOVE software-engineer candidates from the candidates
corpus. 0.11 gap between the worst worker (0.395) and the best
candidate (0.440) — clean distance separation.
Compared to the candidates-only e2e run from 0d1553c:
candidates-only top: c-CAND-00727 at d=0.4404
multi-corpus top: w-4573 at d=0.3265 (a Production Worker)
That's the matrix indexer's whole point made visible: composing
domain-distinct corpora surfaces better matches than single-corpus
search. Without workers in the search space, the staffing query
returned software engineers (wrong domain). With workers, it
returns roles in the right ballpark.
What's still imperfect (signal for component 5 + future work):
- No top-6 worker actually has "Forklift" or "OSHA-30" visible in
metadata; "Production Worker" is semantically nearest in this
sample. Likely needs a larger workers ingest (5000 from 500K)
or skill-keyword boost.
- Status/availability still not gated. The staffing-side
structured filtering gap from 0d1553c persists; relevance filter
(CODE-aware) doesn't address it.
Pipeline timings:
workers ingest: 5000 rows / 19.2s = 260/sec end-to-end
candidates ingest: 1000 rows / 3.1s = 322/sec
multi-corpus query (text → embed → 2 parallel vectord → merge): 14ms
14-smoke regression sweep all green (D1-D6, G1, G1P, G2,
storaged_cap, pathway, matrix, relevance, downgrade).
