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)

J's "let's go" instruction: leave OPEN list behind, push the Go
substrate forward into actual deployment shape. This commit marks
the first time the Go side has run as long-running daemons rather
than per-harness transient processes, and the first time the
shared cross-runtime longitudinal log has carried a Go-emitted
entry alongside the Rust ones.
What landed:
scripts/cutover/start_go_stack.sh — the persistent-stack runbook.
Brings up all 11 daemons (storaged → catalogd → ingestd → queryd
→ embedd → vectord → pathwayd → observerd → matrixd → gateway,
plus chatd-if-not-already-up) in dependency order via nohup +
disown. Anchored pkill per feedback_pkill_scope (never bare
"bin/"). Logs land in /tmp/gostack-logs/<bin>.log, one per daemon.
Verified live state:
- All 11 services healthy on :3110 + :3211-:3220
- gateway → embedd proxy returns nomic-embed-text-v2-moe vectors
- chatd reports 5/5 providers loaded
- No port collision with Rust gateway on :3100
- Daemons stay up after exit of the start script (production shape,
not harness-transient)
audit_baselines.jsonl crosses the runtime boundary:
- 7 Rust-emitted entries (last: ca7375ea 2026-04-27)
- 1 Go-emitted entry (ee2a40c 2026-05-01T07:53:54Z) appended via
./bin/audit_full -append-baseline
- Same envelope shape, same metric set, same drift comparator
semantics — operators running either runtime grow the same log
What this DOES prove:
- Substrate parity at deployment shape (not just unit tests)
- Cross-runtime artifact write-side compatibility (was previously
proven on read side via audit_baselines roundtrip)
- The deploy machinery works end-to-end for the persistent case
What this does NOT prove (still ahead):
- Real coordinator traffic against the Go stack (no nginx flip yet;
devop.live/lakehouse/ still serves through Rust)
- Go-side production materializer (Phase 2 is observer-only)
- Replay tool parity (Phase 7 is observer-only)
- The 5-loop product gate against actual humans
reports/cutover/SUMMARY.md now logs three new rows:
- audit-FULL with 12/12 phases ported
- First Go-emitted audit_baselines entry
- Persistent Go stack live

Closes 4 of the 5 phases the initial audit-FULL port left as
deferred. The pattern: most "deferred" phases didn't actually need
the un-ported Rust pieces — they were observer-mode by design and
just needed to read existing on-disk artifacts.
Phase 1 (schema validators) → ported via exec.Command:
Invokes `go test ./internal/distillation/...` — the Go equivalent
of Rust's `bun test auditor/schemas/distillation/`. New
GoTestModule field on AuditFullOptions controls the package
pattern; empty disables the invocation (test mode, prevents
recursion when audit-full is invoked from inside `go test`).
Phase 2 (evidence materialization) → ported as observer:
Reads data/evidence/ directly and tallies rows + tier-1 source
hits. Doesn't re-run the materializer (which is Rust-side TS).
Emits p2_evidence_rows + p2_evidence_skips metrics matching
Rust shape — drop-in audit_baselines.jsonl entries possible.
Phase 5 (run summary) → ported as observer:
Reads reports/distillation/{run_id}/summary.json + 5 stage
receipts. Validates schema_version=1, run_hash sha256, git_commit
40-char hex, all stage receipts decode as JSON. Full schema
validation (StageReceipt schema) is intentionally NOT ported —
it would require porting the TS schemas/distillation/ validators
in full; basic shape checks catch the load-bearing invariants.
Phase 7 (replay log) → ported as observer:
Reads data/_kb/replay_runs.jsonl, validates last 50 rows parse
as JSON. Skips the live-replay invocation that Rust's phase 7
also does — porting Rust replay.ts is substantial and not in
scope. The "log shape sanity" check is what audit-full actually
needs; the live invocation is a separate concern.
Phase 6 (acceptance gate) — STILL SKIPPED:
Rust acceptance.ts is a TS-only fixture harness with bun-specific
deps. Porting the fixtures (tests/fixtures/distillation/acceptance/)
+ the 22-invariant runner to Go is an ADR-worth undertaking.
Documented in the header comment.
Live-data probe (against /home/profit/lakehouse):
Skips count: 4 → 1 (only phase 6).
Required checks: 6/6 → 12/12 PASS.
New metric: p2_evidence_rows=1055, BYTE-EQUAL to the Rust
pipeline's collect.records_out from the latest summary.json.
Cross-runtime parity now extends across phases 0/1/2/3/4/5/7.
6 new tests:
- TestPhase2_EvidenceTallyFromOnDisk: row + tier-1-hit tallying
- TestPhase5_FullSummaryFlow: complete run-summary fixture passes
- TestPhase5_ShortRunHashCaught: bad run_hash fails required check
- TestPhase7_ReplayLogReadsFromDisk: row-count reporting
- TestPhase7_MalformedTailRowsCaught: structural parse failure
- TestRunAuditFull_FullFixtureFlow updated to seed evidence/ +
reports/distillation/ for the phases now wired.
Cleanup: removed local sortStrings helper (replaced with sort.Strings
now that `sort` is imported for phase 5's mtime-sort).

Same shape of proof as embed_parity.sh for the embed endpoint:
take the just-shipped Go port (ca142b9) and validate it against
the actual production data the Rust legacy emits, not just unit-
test fixtures. Locks the cross-runtime parity that operators
running mixed pipelines depend on.
scripts/cutover/audit_baselines_validate.go:
- Reads /home/profit/lakehouse/data/_kb/audit_baselines.jsonl
- Parses every entry via the Go AuditBaseline struct
- Round-trips the last entry: encode → decode → field-by-field
equality check (catches any silently-dropped JSON keys)
- Calls LoadLastBaseline against the live file (proves the public
API works on real shapes, not just inline parsing)
- Computes BuildAuditDriftTable(first → last) — full-window
lineage drift over the captured baselines
Live-data probe results (reports/cutover/audit_baselines_roundtrip.md):
- 7 entries parse without error
- Round-trip is byte-equal on every metric + every header field
- Drift table fires the expected verdicts:
- p2_evidence_rows 12→82 (+583%) → warn (above 20% threshold)
- p3_accepted/partial/rejected/human 0→non-zero → warn (the
zero-baseline edge case TestBuildAuditDriftTable_ZeroBaseline
was designed to lock — verified now firing on real history)
- p4_* metrics +0% → ok (stable across the window)
What this does NOT prove (documented in the report): the Go-side
audit-FULL pipeline that PRODUCES baselines doesn't exist yet.
Only the load/append/drift substrate is ported. Operators running
audit-full from Go would still need a metric-collection pass —
that's a separate port deliberately not in this wave.
reports/cutover/SUMMARY.md gains a new row alongside the embed
parity entries; cutover-prep verification log keeps the
discipline of "verified against real data, not just fixtures."

5 explicit-negation queries ("Need Forklift Operators in Aurora IL,
NOT in Detroit", "excluding Cornerstone Fabrication roster", etc.)
through the standard playbook_lift harness. Goal: characterize
whether the substrate has negation handling or silently treats
"NOT X" as "X".
Headline: substrate has zero negation handling. Cosine on dense
embeddings tokenizes "NOT in Detroit" identical to "in Detroit"
plus noise — there is no logical-quantifier representation in the
embedding space. This is a structural property of dense embeddings,
not a substrate bug.
Per-query observations:
- Q1 (Aurora IL, NOT Detroit): all top-10 rated 1-2/5 by judge
- Q2 (NOT Beacon Freight): top-1 rated 4/5 — accidentally OK
because role+city signal pulled non-Beacon worker naturally
- Q3 (excluding Cornerstone): unanimous 1/5 across top-10
- Q4 (NOT Detroit-area): all top-10 rated 1-2/5
- Q5 (exclude Heritage Foods): top-1 rated 4/5 — accidentally OK
The judge IS the safety net: when retrieval can't honor the
constraint, the judge refuses to approve any result. That's the
honesty signal — `discovery=0` for the run aggregates it.
No code change. The architectural answer for production is:
- UI surfaces an "exclude" affordance that populates ExcludeIDs
(already supported, added in multi-coord stress 200-worker swap)
- Coordinators don't type natural-language negation — they click
- Substrate's role: surface honesty signal (judge ratings) + don't
pretend to honor unparseable constraints
Adding NL-negation handling at the substrate level would be product
debt — it would let coordinators type sloppier queries that
silently fail when the LLM extractor misses a phrasing. Don't ship
until production traffic demonstrates demand for it.

real_003 left a known-weak hole: shorthand-style queries
("{count} {role} {city} {state} ...") have no separator between
role and city, so a regex can't reliably extract — leaving the
cross-role gate disabled when both record AND query are shorthand.
This commit adds a roleExtractor with regex-first + LLM fallback:
- Regex first (fast, deterministic) — handles need + client_first +
looking from real_003b. ~75% of styles, no LLM cost paid.
- LLM fallback when regex returns empty AND model is configured —
Ollama-shape /api/chat with format=json, schema-tight prompt,
temperature 0. ~1-3s on local qwen2.5.
- Per-process cache — paraphrase + rejudge passes reuse the same
query 4× per run; cache prevents 4× LLM cost.
- Off-by-default — opt-in via -llm-role-extract flag (CLI) and
LLM_ROLE_EXTRACT=1 env var (harness wrapper). real_003b shipping
config unchanged unless explicitly enabled.
8 new tests in scripts/playbook_lift/main_test.go:
- TestRoleExtractor_RegexFirst: LLM not called when regex matches
- TestRoleExtractor_LLMFallback: shorthand goes to LLM
- TestRoleExtractor_LLMOffLeavesEmpty: opt-in default preserved
- TestRoleExtractor_Cache: 3 calls = 1 LLM hit
- TestRoleExtractor_NilSafe: nil receiver runs regex only
- TestExtractRoleViaLLM_HTTPError + _BadJSON: failure paths
- TestRoleExtractor_ClosesCrossRoleShorthandBleed: synthetic
witness for the real_003 scenario — both record + query are
shorthand, regex returns "" for both, LLM produces DIFFERENT
role tokens for CNC vs Forklift, so matrix gate's cross-role
rejection (locked separately in
TestInjectPlaybookMisses_RoleGateRejectsCrossRole) fires
correctly. This is the load-bearing verification.
Reality test real_004 ran the same 40-query stress as real_003 with
LLM extraction on. Cross-style same-role boosts fired correctly
across all 4 styles for Loaders + Packers + Shipping Clerk clusters
(including shorthand → other-style transfer). No cross-role bleed
observed. The reality test alone can't be a clean "with vs without"
comparison (HNSW build is non-deterministic across runs, and
real_004 stochastics didn't trigger a shorthand recording at all),
which is why the unit-test witness exists.
Production note (in real_004_findings.md): LLM extraction is for
reality-test coverage of arbitrary query shapes. Production should
extract role at INGEST time (when the inbox parser already runs an
LLM) and pass already-resolved role through requests — same shape
as multi_coord_stress's existing Demand{Role: ...} model. The hot
path should never need the harness extractor's per-query LLM cost.

Stress-tests the role gate with 40 queries (10 fill_events rows × 4
styles): need, client_first, looking, shorthand. Each row's role +
client + city stays the same; only the surface phrasing changes.
real_003 (original extractor) confirmed the shorthand-vs-shorthand
failure mode: CNC Operator shorthand recording leaked w-2404 onto
Forklift Operator shorthand query within the same Beacon Freight
Detroit cluster. Both record + query had empty role (extractor
returns "" for shorthand because there's no separator between role
and city), gate disabled, distance check passed, bleed fired.
Fix: extended extractRoleFromNeed to handle client_first
("{client} needs N {role} in...") and looking ("Looking for N
{role} at...") patterns. Shorthand left intentionally unmatched —
"Forklift Operator Detroit" is shape-indistinguishable from
"Forklift" + "Operator Detroit" without an LLM extractor or known-
cities lookup.
real_003b (extended extractor) verifies bleed closed across all 4
styles for this dataset. Forklift Operator queries keep w-2136 (the
cold-pass-correct match) regardless of which style the query came
in. Same-role boosts now fire correctly across styles — a CNC
Operator recording made in `looking` style boosts the CNC need-form
query.
scripts/cutover/gen_real_queries.go: added -styles flag with values
need|client_first|looking|shorthand|all (default need preserves
real_001/002 behavior). Tests/reality/real_coord_queries_v2.txt is
the 40-query stress file.
scripts/playbook_lift/main_test.go: 10 sub-tests lock the four
documented patterns + shorthand limitation + lift-suite-style
queries (no clean role, returns empty as expected).
Aggregate metrics:
- real_003 (original): disc=7, lift=7, boost=14, meanΔ=-0.108
- real_003b (extended): disc=11, lift=10, boost=31, meanΔ=-0.202
The growth reflects more LEGITIMATE same-role same-cluster transfer
firing across styles, not bleed (verified by per-cluster bleed
table — Forklift Operator queries unchanged across all 4 styles).
Known limitation documented in real_003_findings.md: same-cluster,
same-role queries in shorthand still embed close enough that a
shorthand recording could bleed onto a different-role shorthand
query if both record + query strip role. Closing this requires
LLM extraction or known-cities lookup at record + query time.

real_001 surfaced same-client+city queries bleeding across roles:
Q#2 (Forklift Operator @ Beacon Freight Detroit) recorded e-6193
in the playbook corpus. Q#5 (Pickers same client+city) and Q#10
(CNC Operator same client+city) embedded within 0.13-0.18 cosine of
Q#2's query — well inside the 0.20 inject threshold — so e-6193
injected on both, demoting the cold-pass-correct workers.
Root cause: the inject distance threshold isn't tight enough on
the same-client+city cluster. Cosine collapses queries that share
city + client + count-token + time-token regardless of role. The
existing judge gate is per-injection at record time and doesn't
fire at retrieve time.
Fix: structural role gate in front of both Shape A boost and
Shape B inject. PlaybookEntry gains Role; SearchRequest gains
QueryRole. When both are non-empty and differ under roleEqual's
case+plural normalization, the entry is rejected before BoostFactor
or judge-gate logic runs.
Backward-compat: empty role on either side disables the gate —
preserves behavior for the lift suite's free-form multi-constraint
queries that have no clean single role. Caller-supplied (not
inferred), so existing recordings unaffected.
Wire-through:
- internal/matrix/playbook.go: Role field, NewPlaybookEntryWithRole,
roleEqual helper with plural+case normalization
- internal/matrix/retrieve.go: QueryRole on SearchRequest, threaded
to both ApplyPlaybookBoost + InjectPlaybookMisses
- cmd/matrixd/main.go: role on POST /matrix/playbooks/record + bulk
- scripts/playbook_lift/main.go: extractRoleFromNeed regex pulls
role from "Need N {role}{s} in" queries (the fill_events shape);
free-form queries fall back to empty (gate disabled)
Tests (5 new):
- TestInjectPlaybookMisses_RoleGateRejectsCrossRole: exact Q#10
scenario (distance 0.135, recorded "Forklift Operator", query
"CNC Operator") — locks the bleed at unit level
- TestInjectPlaybookMisses_RoleGateAllowsSameRole: Forklift Operator
recording fires on Forklift Operators query (plural normalization)
- TestInjectPlaybookMisses_RoleGateBackwardCompat: empty Role on
either side = gate disabled, preserves current behavior
- TestApplyPlaybookBoost_RoleGateRejectsCrossRole: Shape A defense
in depth — boost doesn't fire on cross-role even when answer is
in cold top-K
- TestRoleEqual_PluralAndCase: case + -s + -es plural normalization
Verification (real_002, same query set as real_001):
- Q#5 Pickers @ Beacon Freight: e-6193 → e-8499 (no bleed)
- Q#10 CNC Operator @ Beacon Freight: e-6193 → w-2404 (no bleed)
- Discoveries + lifts unchanged at 2 each (same-role lift still fires)
- Mean Δdist tightens from -0.127 to -0.040 (boosts no longer
pulling distances through the floor on cross-role mismatches)

First retrieval probe with non-synthetic query distribution. Pulls
N rows from /home/profit/lakehouse/data/datasets/fill_events.parquet
(real-shape demand data) and translates each to the natural language
a coordinator would type: "Need {count} {role}s in {city} {state}
starting at {at} for {client}".
Headline: 8/10 cold-pass top-1 = judge-best on real distribution.
Substrate works on queries it was never trained for. v2-moe + workers
corpus carry the load.
Surfaced finding (the real value of running this): same-client+city
queries cluster, and Shape A's distance boost bleeds across roles
within the cluster. Q#2 (Forklift @ Beacon Freight Detroit) records
e-6193 in the playbook corpus. Q#5 (Pickers same client+city) and
Q#10 (CNC Operator same client+city) inherit e-6193 at warm top-1
even though:
- Neither query has its own recorded playbook.
- Neither warm pass triggers a Shape B inject (boosted=0).
- The roles are different staffing categories.
Q#10 specifically demoted the cold-pass-correct w-3759 (judge rating
4 at rank 0) for a worker who was approved by the judge for a
different role on a different query.
Why the lift suite missed it: synthetic queries use 7 disjoint
scenario buckets (forklift+OSHA+WI / CDL+IL / etc.). Real demand
clusters on (client, city). The cluster doesn't exist in the
synthetic distribution.
Why the judge gate doesn't catch it: the gate (5a3364f) is
per-injection at record time. After approval the worker rides Shape A
distance boosts on all later same-cluster queries with no second
gate call.
Becomes new OPEN #1. Fix candidate: role-scoped playbook corpus
metadata + Shape A boost gate on role match. Cheap; doesn't need
new judge calls.

First concrete cutover artifact: scripts/cutover/embed_parity.sh
brings up Go embedd + gateway alongside the live Rust gateway,
hits both /ai/embed and /v1/embed with the same forced model, and
emits a per-date verdict report under reports/cutover/.
Why embed first: the parity invariant is one math identity (cosine
sim of vectors against same input). Retrieve has thousands of edge
cases. If embed parity holds, all downstream vector consumers
inherit confidence; if it doesn't, we catch it in 30s instead of
after a flip.
Verdict 2026-04-30: 5/5 samples cosine=1.000000 with model forced
to nomic-embed-text (v1). Same with nomic-embed-text-v2-moe (both
Ollamas have it loaded). Math is provably equivalent across the
gateway plumbing.
Drift catalog (reports/cutover/SUMMARY.md):
- URL: Rust /ai/embed vs Go /v1/embed
- Wire: Rust {embeddings, dimensions} (plural) vs Go {vectors,
dimension} (singular). Wire-format adapter is the only real
cutover work for this endpoint.
- L2 norm: Rust unit vectors (~1.0); Go raw Ollama (~20-23). Same
direction (cos=1.0); harmless under cosine-distance HNSW (which
is Go vectord's default), but worth fixing in internal/embed/
before extending to euclidean indexes.
reports/cutover/ now tracked (joined the scrum/ + reality-tests/
exemptions in .gitignore).
Next probe: /v1/matrix/retrieve ↔ Rust /vectors/hybrid for the
real user-facing retrieve path. Embed parity gives that probe a
clean foundation.

Phase 1c-only tracing (commit 7e6431e) was the proof-of-concept.
This commit threads tracing through every phase: baseline / fresh-
resume / inbox burst / surge / swap / merge / handover (verbatim +
paraphrase) / split / reissue. Each phase is a parent span; each
matrix.search / LLM call inside is a child span.
Refactor:
- One run-level trace is created at driver startup.
- New startPhase(name, hour, meta) helper emits a phase span as a
child of the run trace; subsequent emitSpan calls nest under it.
- New tracedSearch(spanName, query, corpora, ...) wraps matrixSearch
with span emission. Every search call site replaced with this so
the input/output JSON (query, corpora, k, playbook, exclude_n →
top-K ids, top1 distance, boost/inject counts) lands in Langfuse.
- Phase 4b's paraphrase generation also emits llm.paraphrase spans.
- Phase 1c's existing inline span emission converted to use the new
helpers (no more inboxTraceID variable).

Runs #003-#009 surfaced the same finding: fresh workers added
mid-run to the main 'workers' vectord index (5K items) reliably
*absorbed* (HTTP 200) but failed to *surface* in semantic queries
even with content-matching prompts. Distances on the verify queries
sat at 0.25-0.65 against existing workers; fresh items were beyond
top-K. Better embedder (v2-moe) didn't help — distances got TIGHTER
on existing items, pushing fresh items further out of reach.
Root cause: coder/hnsw incremental adds to a populated graph land
in poorly-connected regions and disappear from search traversal.
Known property of HNSW post-build adds; not a bug.
Fix: two-tier index pattern (canonical NRT search architecture).
Fresh content goes to a small "hot" corpus (fresh_workers); main
queries include it in the corpora list and merge results. Hot corpus
has no recall crowding because it's tiny; periodic batch job (post-
G3) merges it into the main index.
Implementation:
- ensureFreshIndex(hc, gw, name, dim) — idempotent POST
/v1/vectors/index. 409 from re-create treated as "already there."
- ingestFreshWorker now takes idx parameter so callers can target
fresh_workers instead of workers.
- multi_coord_stress phase 1b creates fresh_workers index + ingests
3 fresh workers there + searches verifyCorpora=[workers,
ethereal_workers, fresh_workers].
Run #010 result:
fresh-001 (Senior tower crane rigger NCCCO Chicago)
top-1: fresh-001 from fresh_workers, distance 0.143
fresh-002 (Bilingual Spanish/English OSHA trainer Indianapolis)
top-1: fresh-002 from fresh_workers, distance 0.146
fresh-003 (FAA Part 107 drone surveyor Chicago)
top-1: fresh-003 from fresh_workers, distance 0.129
3/3 fresh workers surface at top-1 — the absorption-but-not-
findable issue from runs #003-#009 is closed.
All other metrics held: diversity 0.007, determinism 1.000,
verbatim handover 4/4, paraphrase handover 4/4, swap Jaccard 0.000,
inbox burst all 6 events accepted + traced to Langfuse.
This is the final structural fix for the multi-coord stress
suite. Phase 3 is feature-complete.

The Rust side has Langfuse tracing already (gateway/v1/langfuse_trace.rs);
this commit lands Go-side parity so the multi-coord stress harness can
emit traces visible at http://localhost:3001.
internal/langfuse/client.go:
- Minimal Trace + Span + Flush API mirroring what the Rust emitter
uses. Auth: Basic over public_key:secret_key.
- Best-effort posture: errors are slog.Warn'd, never block calling
paths. Same fail-open as observerd's persistor (ADR-005 Decision
5.1) — observability is a witness, not a gate.
- Events buffered until 50, then auto-flushed; explicit Flush() at
process exit.
- Each Trace/Span returns its id so callers can build hierarchies.
multi_coord_stress driver wiring:
- New --langfuse-env flag (default /etc/lakehouse/langfuse.env).
Empty / missing / unparseable file → skip tracing with a logged
warning; run still proceeds.
- Phase 1c (inbox burst) now emits one parent trace + 4 spans per
inbox event:
1. observerd.inbox.record (post to /v1/observer/inbox)
2. llm.parse_demand (qwen2.5 → structured fields)
3. matrix.search (parsed query → top-K)
4. llm.judge_top1 (rate top-1 vs original body)
Each span carries input/output JSON + start/end times so the
Langfuse UI shows a full waterfall per event.
Run #009 result:
Trace landed: "multi_coord_stress phase 1c inbox burst"
Observations attached: 24 (= 6 events × 4 spans)
Tags: stress, phase-1c, inbox
Browseable at http://localhost:3001 by tag query.
Other harness metrics: diversity 0.016, determinism 1.000,
verbatim handover 4/4, paraphrase handover 4/4 — all unchanged
by the tracing addition (best-effort post in parallel).
Phase 1c is the proof-of-concept; future commits can wrap other
phases (baseline / merge / handover / split) in traces too. Once
that's done, the entire stress run becomes scrubbable in Langfuse
without grepping the events JSON.

Run #007 surfaced a tradeoff: LLM-parsed inbox queries produce much
tighter cosine distances (0.05-0.10 in three cases) but lose the
"system has no good match" signal that high-distance results give.
A coordinator UI showing only distance can't tell wrong-domain
matches apart from real ones.
Fix: judge re-rates top-1 against the ORIGINAL inbox body (not the
LLM-parsed query). Coordinators see both:
- distance: how close was retrieval in vector space
- rating: does this person actually fit the original ask
The pair tells the honest story.
Run #008 result on the 6 inbox events:
Demand Top-1 Distance Rating Reading
─────────────────────────────────────────────────────────────
Forklift Cleveland w-3573 0.29 4 Strong
Production Indy e-1764 0.41 3 Adjacent
Crane Chicago e-7798 0.23 1 TIGHT BUT WRONG
Bilingual safety Indy w-3918 0.05 5 Perfect
Drone Chicago e-1058 0.06 5 Perfect (verify e-1058)
Warehouse Milwaukee w-460 0.32 4 Strong
The crane-Chicago case is the architectural-honesty signal at work:
distance 0.23 says "tight match" but the judge says rating 1 reading
the original body. A coordinator seeing only distance would ship the
wrong worker; coordinator seeing distance+rating sees the disagreement
and escalates.
Net distribution: 5/6 rated 3+ (acceptable→perfect), 1/6 rated 1
(irrelevant despite tight cosine). The substrate-honesty signal is
recovered without losing the LLM-parse quality wins.
Cost: 6 extra judge calls (~9s on qwen2.5). Production amortizes
when judge runs only on top-1 of high-priority inbox events; the
search-cost-vs-quality tradeoff lives in the priority gate.
Implementation:
- New JudgeRating int field on Event (omitempty so non-judged
events stay clean in JSON)
- New judgeInboxResult helper, reusing the same prompt structure as
playbook_lift's judgeRate. The two could share an internal package
if a third judge consumer appears.

Replaced the hard-coded DemandQuery on inbox events with an actual
LLM call: each email/SMS body is parsed by qwen2.5 (format=json,
schema-anchored) into structured {role, count, location, certs,
skills, shift}. The driver then composes a query string from those
fields and runs matrix.search.
This is the real-product flow that the Phase 3 stress test was
asking for: real bodies → real LLM parsing → real search. Before
this commit, the DemandQuery was my hand-crafted string, which
made the inbox phase trivial.
Run #007 result vs #006 (same bodies, parser swapped):
All 6 inbox events parsed cleanly — qwen2.5 nailed:
"Need 50 forklift operators in Cleveland OH for Monday day
shift. OSHA-30 + active forklift cert required."
→ {role:"forklift operator", count:50, location:"Cleveland, OH",
certs:["OSHA-30","active forklift cert"], skills:[], shift:"day"}
Other 5 similarly faithful (indy stayed as "indy", count
defaulted to 1 when unspecified, no hallucinated fields).
LLM-parsed queries produced TIGHTER matches than hard-coded:
Demand #006 dist #007 dist Δ
Crane Chicago 0.499 0.093 -82%
Drone Chicago 0.707 0.073 -90%
Bilingual safety 0.240 0.048 -80%
Forklift Cleveland 0.330 0.273 -17%
Production Indy 0.260 0.399 +53%
Warehouse Milwaukee 0.458 0.420 -8%
Three matches landed at distance < 0.10 — verbatim-replay-tight
territory. Structured queries embed sharper than conversational
hand-crafted strings.
Other metrics unchanged: diversity 0.000, determinism 1.000,
verbatim handover 4/4, paraphrase handover 4/4.
Tradeoff worth flagging: the drone-Chicago case dropped from
distance 0.71 (clear "we don't have one") to 0.07 (confident match
returned). The OOD honesty signal weakens when LLM-parsed structure
makes any closest-neighbor look tight. Future Phase 4 work: judge
re-rates the top match before surfacing, so coordinators see "your
demand was for X but the closest match scored 2/5" rather than just
the worker ID + distance.
Substrate cost: +6 LLM calls per inbox burst (~9s on qwen2.5).
Production would amortize via a small dedicated parser model.

Phase 3 ask: real-world inbox-style event injection during the stress
test. Coordinators in production receive emails + SMS that trigger
contract responses; the substrate has to RECORD these signals AND
react with a search using the embedded demand. This commit lands the
endpoint and exercises it end-to-end in the stress harness.
observerd surface:
- New POST /observer/inbox route — accepts {type, sender, subject,
body, priority, tag} and records as ObservedOp with
Source=SourceInbox. Type must be email|sms; body required;
priority defaults to medium. The handler ONLY records — downstream
triggers (search, ingest, etc.) are the caller's concern, recorded
separately. Keeps the witness role pure.
- New observer.SourceInbox = "inbox" alongside SourceMCP /
SourceScenario / SourceWorkflow.
- Three contract tests on the new route (happy path / bad type / empty
body), router-mount test extended, all green.
Stress harness phase 1c (Hour 9):
- 6 inbox events fire in priority order (urgent → high → medium):
2 urgent emails (forklift Cleveland, production Indianapolis)
1 high email (crane Chicago)
1 high sms (bilingual safety Indianapolis)
1 medium sms (drone Chicago)
1 medium email (warehouse Milwaukee FYI)
- Each event:
1. POSTs to /v1/observer/inbox (recorded by observerd)
2. Triggers matrix.search using a parsed demand (the demand
extraction is hard-coded for now; production needs a small
LLM to parse from body)
3. Captures both as events in the run JSON
Run #006 result (with v2-moe embedder + all phases including inbox):
Diversity:
Same-role-across-contracts Jaccard = 0.000 (n=9)
Different-roles-same-contract Jaccard = 0.046 (n=18)
Determinism: 1.000
Verbatim handover: 4/4 (100%)
Paraphrase handover: 4/4 (100%)
Inbox burst:
6/6 events accepted by observerd (200 status, all recorded)
6/6 triggered searches produced distinct top-1 worker IDs
distance distribution: 0.24 (Indy production) → 0.71 (Chicago
drone surveyor — honest stretch since drones aren't in the
5K-worker corpus, system surfaces closest neighbor at high
distance rather than fabricating)
The drone-Chicago case is the architectural-honesty signal: when
the demand asks for a specialist NOT in the roster, the system
returns the closest semantic neighbor with a distance that flags
"this is a stretch." Coordinators reading distances see "we don't
have a great match here" rather than a confident wrong answer.
Total events captured: 67 (was 61 pre-inbox).

Local Ollama has three embedding models loaded:
nomic-embed-text:latest 137M 768d (previous default)
nomic-embed-text-v2-moe:latest 475M 768d (this commit's default)
qwen3-embedding:latest 7.6B 4096d (would require dim change)
v2-moe is a drop-in upgrade — same 768 dim, 3.5× more params, MoE
architecture. Workers index doesn't need rebuilding, just future ingests
embed with the stronger model.
Run #005 result on the multi-coord stress suite:
Diversity (same-role-across-contracts): 0.080 → 0.000 (n=9)
→ MoE is more discriminating: zero worker overlap across
Milwaukee / Indianapolis / Chicago for shared role names.
The geo + cert + skill context fully separates worker pools.
Different-roles-same-contract: 0.013 → 0.036 (still ~96% diff)
Determinism: 1.000 (unchanged)
Verbatim handover: 4/4 (100%)
Paraphrase handover: 4/4 (100%)
200-worker swap: Jaccard 0.000 (unchanged — still perfect)
Fresh-resume verify: STILL doesn't surface fresh workers in top-8.
With v2-moe, distances increased (top-1 = 0.43–0.65 vs v1's 0.25–0.39)
— the embedder is MORE discriminating, but the fresh worker's
vector still doesn't outrank the 8th-best existing worker. Now
suspect of being an HNSW post-build add issue (coder/hnsw
incremental adds can land in hard-to-reach graph regions, not an
embedder problem). Better embedder didn't fix it; needs a
different strategy: full index rebuild after fresh adds, or
explicit playbook-layer score boost for fresh workers, or
hybrid (keyword + semantic) retrieval. Phase 3 investigation.
Cost: ingest is ~5× slower (workers 20s→100s; ethereal 35s→112s).
Acceptable for the quality jump on diversity. Real production with
incremental ingest won't pay this once-per-deploy.

Three Phase 2 additions land in this commit:
1. matrix.SearchRequest gains ExcludeIDs ([]string) — filters specific
worker IDs out of results post-retrieval, AND skips them at the
playbook boost+inject step (so excluded answers can't sneak back
via Shape B). Real-world driver: coordinator placed N workers,
client asks for replacements, system needs alternatives, not the
same N. Threaded through retrieve.go after merge but before
metadata filter so excluded IDs don't waste post-filter top-K slots.
2. New harness phase 2b: 200-worker swap simulation. Captures the
top-K from alpha's warehouse query, then re-issues with
exclude_ids=<placed>. Result Jaccard(orig, swap) measures whether
the substrate finds genuine alternatives.
3. New harness phase 1b: fresh-resume mid-run injection. Three new
workers ingested via /v1/embed + /v1/vectors/index/workers/add,
then verified findable via semantic queries matching resume content.
Plus Hour labels on every event (operational narrative: 0/6/12/18/
24/30/36/42/48) and a refactor of captureEvent to take hour as a
param.
Run #003 + #004 results (5K workers + 10K ethereal):
Diversity (#004):
Same-role-across-contracts Jaccard = 0.080 (n=9)
Different-roles-same-contract Jaccard = 0.013 (n=18)
Determinism: 1.000 (#004 unchanged)
Verbatim handover: 4/4 = 100%
Paraphrase handover: 4/4 = 100%
Phase 2b — 200-worker swap (Jaccard 0.000):
8 originally-placed workers fully replaced by 8 alternatives.
ExcludeIDs substrate change works end-to-end — boost AND inject
both honor the exclusion, so excluded workers don't return via
the playbook either.
Phase 1b — fresh-resume injection: REAL PRODUCT FINDING.
Substrate ABSORPTION is fine — 3 /v1/vectors/index/workers/add
calls at 200 status, 3 vectors persisted. But none of the 3
fresh workers surfaced in top-8 even with semantic queries
matching their resume content (e.g. "Senior tower crane rigger
NCCCO Chicago" vs fresh-001's resume "Senior rigger with 12
years tower-crane signaling..." NCCCO + Chicago).
Top-1 came from existing workers at distance ~0.25; fresh
workers' distances must be > 0.25, pushing them past rank 8.
Cause: dense retrieval at 5000+ workers means many existing
profiles cluster near any specific query in cosine space;
nomic-embed-text-v2 (137M) introduces enough noise that a
fresh worker doesn't reliably outrank them just because the
text content overlaps.
Workarounds (Phase 3 work): (a) hybrid retrieval (keyword +
semantic), (b) playbook-layer score boost for fresh adds,
(c) larger embedder. Documented in run #004 report.

Phase 1 had two known gaps: (1) the 3 contracts had zero shared role
names, so same-role-across-contracts Jaccard was vacuous (n=0); (2)
the verbatim handover at 100% was the trivial case, not the hard
learning test (paraphrased queries against another coord's playbook).
Both fixed in this commit.
Contract redesign — all 3 contracts now share warehouse worker /
admin assistant / heavy equipment operator roles, plus a unique
specialist per contract (industrial electrician / bilingual safety
coord / drone surveyor — the "specialist not on the standard roster"
case from J's spec). Counts and skill mixes vary per region.
New driver phase 4b — paraphrase handover. Bob runs qwen2.5-paraphrased
versions of Alice's contract queries against Alice's playbook
namespace. Tests whether institutional memory propagates across
coordinators AND across natural wording variation that Bob would
introduce when running Alice's contract.
Run #002 result (5K workers + 10K ethereal_workers, 4 demand × 3
coords + paraphrase handover):
Diversity (the question J asked: locking or cycling?):
Same-role-across-contracts Jaccard = 0.119 (n=9)
→ 88% of workers DIFFER across regions for the same role name.
Milwaukee warehouse vs Indianapolis warehouse vs Chicago
warehouse pull mostly distinct top-K from the same population.
The system locks into geo+cert+skill context, not cycling.
Different-roles-same-contract Jaccard = 0.004 (n=18)
→ role-specific retrieval works (unchanged from Phase 1).
Determinism: Jaccard = 1.000 (n=12) — unchanged.
Learning:
Verbatim handover 4/4 = 100% (trivial case, expected)
Paraphrase handover 4/4 = 100% (HARD case — passes!)
Of those 4 paraphrase recoveries:
- 2 used boost (Alice's recording was already in Bob's
paraphrase top-K; ApplyPlaybookBoost re-ranked to top-1)
- 2 used Shape B inject (recording wasn't in Bob's
paraphrase top-K; InjectPlaybookMisses brought it in)
The boost/inject mix is healthy — both paths are used and both
produce correct top-1s. Multi-coord institutional memory propagation
is empirically working under wording variation.
Sample warehouse worker top-1s across contracts (proves diversity):
alice / Milwaukee → w-713
bob / Indianapolis → e-8447
carol / Chicago → e-7145
Three different workers from the same 15K-person population,
selected on geo+cert+skill context.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three coordinators (alice / bob / carol) with three contracts
(Milwaukee distribution / Indianapolis manufacturing / Chicago
construction). 7-phase scenario runner: baseline → surge → merge →
handover → split → reissue → analysis. Each coord has a separate
playbook namespace (playbook_{name}) so institutional memory stays
isolated by default but transferable on demand.
Phase 1 deliberately skips the 48-hour clock, email/SMS endpoints,
and Langfuse tracing — those are Phase 2/3.
Run #001 (52 events, 4 queries × 3 coords × 2 demand flavors):
Diversity:
Different-roles-same-contract Jaccard = 0.004 (n=18)
→ role-specific retrieval is working perfectly. Different
roles within one contract pull totally different worker
pools. System is NOT cycling; locks into per-role retrieval.
Same-role-across-contracts Jaccard = N/A (n=0)
→ TEST-DESIGN ISSUE: the 3 contracts use distinct role names
per industry (warehouse worker / production worker / general
laborer), so no exact-name overlaps exist. Phase 2 should
either share at least one role across contracts OR add a
skill-based diversity metric.
Determinism: Jaccard = 1.000 (n=12)
→ HNSW + Ollama retrieval is fully deterministic on identical
query text. coder/hnsw + nomic-embed-text are stable.
Learning: handover hit rate = 4/4 = 100%
→ Bob inherits Alice's recordings perfectly when bob runs
identical queries with alice's playbook namespace. CAVEAT:
this tests the trivial verbatim case, not paraphrase handover.
The harder test (bob runs paraphrased queries with alice's
playbook) is Phase 2 work.
Per-event capture in JSON: every matrix.search response is logged
with phase / coordinator / contract / role / query / top-K IDs +
distances + per-corpus counts + boosted/injected counts. Reviewable
via:
jq '.events[] | select(.phase == "merge")'
jq '.events[] | select(.coordinator == "alice")'
jq '.events[] | select(.role == "warehouse worker")'
Notable finding from per-event: carol's "general laborer" and "crane
operator" queries both surface w-1009 as top-1, with crane operator
at distance 0.098 (very tight) and general laborer at 0.297. The
system found a worker who legitimately covers both roles — realistic
for small construction crews.

The rank-based "lift" metric (warm-top-1 == cold-judge-best) doesn't
distinguish "Shape B surfaced a strictly-better answer" from "Shape B
shuffled ranks but quality is unchanged" from "Shape B replaced a good
answer with a wrong one." This commit adds Pass 4: judge warm top-1
with the same prompt as cold ratings, then bucket the comparison.
Implementation:
- New --with-rejudge driver flag (default off).
- New WITH_REJUDGE harness env (default 1, on for prod runs).
- queryRun gains WarmTop1Metadata (cached during Pass 2 for the
rejudge call) + WarmTop1Rating *int (nil-distinguishable; nil = no
rejudge, 0..5 = rating).
- summary gains RejudgeAttempted, QualityLifted, QualityNeutral,
QualityRegressed (counts of warm-rating > / == / < cold-rating).
- Markdown headline gains a Quality block when rejudge ran.
- ~21 extra judge calls (~30s on qwen2.5).
Run #005 result (split inject threshold 0.20 + paraphrase + rejudge):
Quality lifted 5 / 21 (24%) — 3× +2 rating, 2× +1 rating
Quality neutral 13 / 21 (62%) — includes OOD queries holding 1
Quality regressed 3 / 21 (14%)
Net rating delta +3 across 21 queries (+0.14 average)
The 5 lifts were all rating-2 cold replaced with rating-3 or rating-4
warm — Shape B took mediocre matches and substituted substantively
better ones. The 3 regressions were small (-1, -1, -3).
Q11 is the cautionary tale: cold top-1 "production line worker"
(rating 4) got replaced by Q1's recorded "forklift OSHA-30 operator"
e-5729 (rating 1). Adjacent-domain cross-pollination — production
worker and forklift operator embed within 0.20 cosine because both
are warehouse-adjacent staffing queries, even though the judge
correctly distinguishes them. The split-threshold defense (0.5 boost
/ 0.20 inject) catches OOD cross-pollination (Q19/Q20/Q21 all stayed
neutral at rating 1) but not adjacent-domain cross-pollination.
Net product verdict: working, net-positive on quality, but the worst
case (Q11 4→1) is customer-visible and warrants a tighter inject
threshold OR an additional gate beyond cosine distance. Filed in
STATE_OF_PLAY OPEN as a follow-up.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Run #003 surfaced rampant cross-pollination: Q2's "OSHA-30 forklift
Wisconsin" recording (w-4435) became warm top-1 for Q19 (dental
hygienist), Q20 (RN), Q21 (software engineer), and 6 other unrelated
staffing queries. Cause: InjectPlaybookMisses inherited the same
DefaultPlaybookMaxDistance (0.5) as the boost path, but inject is
structurally riskier than boost — boost only re-ranks results that
already retrieved on their own merits, while inject FORCES a result
into top-K, so a loose match cross-pollinates wrong-domain answers.
Empirical motivation from v3:
Implied playbook hit distances for cross-pollinated cases: 0.20-0.46
Implied distances for the 6/6 paraphrase recoveries: 0.23-0.30
Threshold of 0.20 should keep most paraphrases, kill the OOD bleed.
Implementation:
- New DefaultPlaybookMaxInjectDistance = 0.20 in playbook.go.
- New PlaybookMaxInjectDistance field on SearchRequest (override).
- InjectPlaybookMisses signature gains maxInjectDist param; hits whose
Distance exceeds it are skipped (boost path may still re-rank them).
- TestInjectPlaybookMisses_RespectsInjectThreshold locks the contract
with one tight + one loose hit, asserting only the tight one injects.
- Existing tests pass explicit threshold (0 = default for tight tests,
0.5 for the dedupe test which uses 0.30 hits).
Run #004 result on identical queries with the split threshold:
Verbatim discovery 8 (vs v3's 6 — judge variance, separate)
Verbatim lift 6 / 8 (75%)
Paraphrase top-1 6 / 8 (75%)
Paraphrase any-rank in K 6 / 8
OOD queries Q19/Q20/Q21 ALL show warm top-1 = cold top-1 (no
injection) — cross-pollination eliminated where it was wrong-direction.
Mean Δ top-1 distance dropped from -0.164 (v3, distorted) to -0.071
(v4, comparable to v1's -0.053).
Two paraphrases missed in v4 (Q9, Q15) were ones where qwen2.5
rephrased liberally enough to drift past 0.20 — Q9: "Inventory
specialist..." → "Individual needed for inventory management..." and
Q15: "Engaged warehouse associate..." → "Warehouse associate currently
engaged with a robust history...". The system correctly refusing to
inject when it's not confident is the right product behavior; the
boost path still re-ranks recorded answers when they appear in regular
retrieval.
The Q6 ↔ Q7 cross-pollination ("Forklift-certified loader" ↔
"Hazmat warehouse worker") is legitimate — these are genuinely similar
staffing queries and the judge ranks both directions as plausible.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The v0 boost-only stance documented in internal/matrix/playbook.go:22-27
("the boost only re-ranks results that ALREADY surfaced from the regular
retrieval") couldn't promote recorded answers that dropped out of a
paraphrase's top-K. playbook_lift_002 surfaced exactly that gap: 0/2
paraphrase recoveries because the recorded answers weren't in regular
retrieval at all (rank=-1).
Shape B: when warm-pass retrieval doesn't surface a playbook hit's
answer, inject a synthetic Result for it directly. Distance =
playbook_hit_distance × BoostFactor — same formula as the boost path so
injections land in comparable distance space. Caller re-sorts +
truncates after both boost and inject have run.
Result on playbook_lift_003 (Shape B + paraphrase pass):
Verbatim discovery 6
Verbatim lift 2 / 6
**Paraphrase top-1** **6 / 6**
Paraphrase any-rank in K 6 / 6
Mean Δ top-1 distance -0.1637 (warm closer than cold)
Every paraphrase the judge generated landed the v1-recorded answer at
top-1 of the new query's results. The learning property holds — cosine
on embed(paraphrase) finds the recorded query's vector within
DefaultPlaybookMaxDistance (0.5), and Shape B injects the answer.
Verbatim lift dropped from v1's 7/8 because Shape B cross-pollinates
recorded answers across queries. w-4435 (Q2's recording) appears as
warm top-1 for several other queries because their embeddings are
within the playbook hit threshold of "OSHA-30 forklift Wisconsin." This
is a feature, not a bug — the matrix layer's purpose is to share
knowledge across queries — but the lift metric only counts "warm top-1
== cold judge best," so cross-pollinated lifts don't register. A v3
metric would re-judge warm pass to measure true judge improvement.
Tests:
- TestInjectPlaybookMisses_AddsMissingAnswers — primary claim
- TestInjectPlaybookMisses_SkipsAnswersAlreadyPresent — no double-inject
- TestInjectPlaybookMisses_DedupesPerAnswer — multi-hit same answer
- TestInjectPlaybookMisses_EmptyHits — fast-path no-op
Driver fix: ParaphraseRecordedRank int → *int. The `omitempty` int
silently dropped rank=0 (top-1, the WANTED value) from JSON, making the
v003 report show "null" instead of "0" for every successful recovery.
Pointer keeps nil/rank-0 distinguishable.

Adds an opt-in Pass 3 to the lift driver: for each query whose Pass 1
recorded a playbook, ask the judge to rephrase the query, then re-query
with playbook=true and check whether the recorded answer surfaces in
top-K. This is the test the v1 report's caveat #3 explicitly flagged
as the actual learning-property gate (not the cheap verbatim case).
Implementation:
- New flag --with-paraphrase on the driver (default off).
- New WITH_PARAPHRASE env in the harness (default 1, on for prod runs).
- New paraphrase_* fields on queryRun + summary, // 0 fallback in jq so
re-rendering verbatim-only evidence stays clean.
- generateParaphrase() calls the same judge model with format=json and
a tight schema; temperature=0.5 for variance without domain drift.
- Markdown report adds a paraphrase per-query table (only when the
pass ran) and an honesty caveat about judge-also-rephrases coupling.
Run #002 result (reports/reality-tests/playbook_lift_002.{json,md}):
Verbatim lift 2/2 (100% — Q7 + Q13, both stable from v1)
Paraphrase top-1 0/2
Paraphrase any-rank in K 0/2
Both paraphrases dropped the recorded answer OUT of top-K entirely
(rank=-1). This isn't a paraphrase-quality problem — qwen2.5's outputs
preserved intent ("Hazmat-certified warehouse worker comfortable with
cold storage" → "Warehouse worker with Hazmat certification and
experience in cold storage"). It's the v0 boost-only stance documented
in internal/matrix/playbook.go:22-27: the boost only re-ranks results
that ALREADY surfaced from regular retrieval. If paraphrase's cosine
retrieval doesn't include the recorded answer in top-K, no boost can
promote it.
The "Shape B" upgrade mentioned in the playbook.go comment — inject
playbook hits directly even when they weren't in the top-K — is what
would close this gap. The reality test surfaced exactly the gap the
docs warned about. Worth filing as the next product gate.
Run-to-run variance also visible: v1 had 8 discoveries, v2 had 2.
HNSW insertion order + judge variance both contribute. Stability of
Q7 and Q13 across both runs (lifted in v1 AND v2) is the most reliable
signal in the dataset.

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)

migrate the reality-test harness's judge-model default from a
hardcoded "qwen3.5:latest" string to cfg.Models.LocalJudge.
resolution priority: explicit -judge flag > $JUDGE_MODEL env >
cfg.Models.LocalJudge from lakehouse.toml > hardcoded fallback.
bumping the judge for run #N+1 now means editing one line in
lakehouse.toml [models].local_judge — no Go file or shell script
edits required.
changes:
- scripts/playbook_lift/main.go: -config flag added, judge default
flips to "" so resolution chain runs. Imports internal/shared for
config loader.
- scripts/playbook_lift.sh: JUDGE_MODEL no longer defaulted in bash;
EFFECTIVE_JUDGE resolved by mirror-of-the-Go-chain (env > config
grep > qwen3.5:latest fallback). Used for the Ollama presence
check + report header. Pre-flight grep avoids requiring jq just
to read the toml.
- reports/reality-tests/README.md: documents the 4-step priority
chain.
verified all 4 paths produce the expected judge:
- config (no env): qwen3.5:latest (from lakehouse.toml)
- env override: env wins
- flag override: flag wins over env
- missing config: DefaultConfig fallback still gives qwen3.5:latest
just verify PASS.

First reality test driver. Two-pass design:
- Pass 1 (cold): matrix.search use_playbook=false → small-model judge
rates top-K → record playbook entry pointing at the highest-rated
result (which may NOT be top-1 by distance — that's the discovery).
- Pass 2 (warm): same queries with use_playbook=true → measure
ranking shift. Lift = real if recorded answer becomes top-1.
Files:
- scripts/playbook_lift/main.go driver (391 LoC)
- scripts/playbook_lift.sh stack-bring-up + report gen
- tests/reality/playbook_lift_queries.txt query corpus (5 placeholders;
J writes real 20+)
- reports/reality-tests/README.md framework + interpretation
- .gitignore track reports/reality-tests/
but ignore per-run JSON evidence
This answers the gate from project_small_model_pipeline_vision.md:
"the playbook + matrix indexer must give the results we're looking
for." Without ground-truth labels, the LLM judge is the proxy — the
same small-model thesis applied to evaluation. Honest about that
limitation in the generated reports.
Driver compiles clean; full run requires Ollama + workers/candidates
ingest. Skips cleanly if Ollama absent.

Audited stash-clean c7e3124 (30 commits past rerun-1 4840c10).
3 HIGH risks closed (R-002 internal/shared, R-003 internal/storeclient,
R-008 queryd/db.go). 3 advanced to partial (R-001 via fail-loud-bind +
opt-in auth, R-006 via g2_smoke_fixtures, R-007 via ADR-003 auth.go).
Biggest move: Agent Memory Correctness 4 → 9 — pathway Mem0 ops
(ADD/UPDATE/REVISE/RETIRE/HISTORY) all tested, including cycle-detection
and retired-trace-exclusion. Sprint 2 acceptance criteria are now
verified code, not design-bar work.
Two new findings:
- F1 (MED): cmd/{matrixd,observerd,pathwayd}/main_test.go absent —
reopens R-005 against new daemons.
- F2 (LOW): scripts/staffing_*/main.go flag-defaults reach
/home/profit/lakehouse/data/...
Evidence under reports/scrum/_evidence/rerun2/ (local; per
.gitkeep convention).

Re-runs the SCRUM.md framework against HEAD (4840c10) to score the
delta from the audit baseline at 91edd43. Composite +8.
Scoring deltas:
Reproducibility 7 → 9 (just verify, just doctor, pre-push hook)
Test Coverage 6 → 8 (168 proof harness assertions; Go-test
gaps in shared/storeclient remain)
Trust Boundary 7 → 7 (no code change; R-001/R-007 open)
Memory Correctness 3 → 4 (vectord persistence proven; Mem0
pathway/playbook still not ported)
Deployment Readiness 4 → 5 (just doctor; REPLICATION/systemd open)
Maintainability 8 → 8 (spine unchanged; harness obeys
CLAUDE_REFACTOR_GUARDRAILS)
Risk register changes:
R-004 (smokes not gated) CLOSED — just verify + pre-push hook
R-005 (cmd/main.go untested) partial — proof harness covers wiring
R-012 (empty tests/ dir) CLOSED — populated by harness
R-001/R-002/R-003/R-006/R-007/R-008/R-009/R-010 unchanged
Sprint 0 progress:
S0.1 just doctor DONE
S0.3 just verify + pre-push DONE
S0.6 tests/ dir cleanup DONE
S0.2 just smoke-fixtures open
S0.4 cmd/main_test × 6 partial (harness coverage; go-test gap)
S0.5 shared/storeclient tests open (HIGH risks still unaddressed)
New finding from this rerun (worth recording):
Queryd refresh-tick race in 04_query_correctness — cache-warm
binaries fire SELECTs faster than queryd's 500ms refresh tick.
Caught by integration mode going 104/0/1 → 102/1/1, fixed at
4840c10 with proof_wait_for_sql helper. Exactly the failure-mode
the harness was designed to catch.
Original 5 audit reports preserved as immutable history at
91edd43; this file documents the delta only.

Adapts docs/SCRUM.md framework (originally written for the
matrix-agent-validated repo) to the Go rewrite. Five deliverables:
golang-lakehouse-scrum-test.md top-line + scoring + verdict
risk-register.md 12 findings, R-001..R-012
claim-coverage-table.md claim/test/risk for Sprint 2
sprint-backlog.md 5 sprints, ~2 weeks of work
acceptance-gates.md DoD as runnable commands
Every claim cites file:line, command output, or "missing evidence."
Smoke chain ran clean (33s wall, all 9 PASS) and is captured in
reports/scrum/_evidence/smoke_chain.log (gitignored — runtime artifact).
Scoring:
Reproducibility 7/10 9 smokes deterministic, no just/CI gate
Test Coverage 6/10 internal/ packages tested, 6/7 cmd/ aren't
Trust Boundary 7/10 escapes ok, zero auth, /sql is RCE-eq off-loopback
Memory Correctness 3/10 pathway/playbook/observer not yet ported
Deployment Readiness 4/10 no REPLICATION, no env template, no systemd
Maintainability 8/10 no god-files, 7 lean binaries, ADRs current
Top three risks:
R-001 HIGH queryd /sql + DuckDB + non-loopback bind = RCE-equivalent
R-002 HIGH internal/shared (server.go + config.go) zero tests
R-003 HIGH internal/storeclient zero tests, used by 2 services
R-004 MED 9-smoke chain green but not gated (no justfile/hook)
The audit is the work; refactors come after. Sprint 0 owns coverage
+ CI gating; Sprint 1 owns trust-boundary decisions; Sprints 2-3 are
mostly design-bar work for unbuilt agent components.
.gitignore exception: /reports/* + !/reports/scrum/ keeps reports/
a runtime-artifact directory while exposing reports/scrum/ as
tracked documentation. Mirrors the pattern future audit passes will
land in.
